Information Applicable to Our Business

International Operations

 

The Company has several operations located outside of the United States. These operations manufacture, assemble and/or procure and market Hubbell products and services for both the Utility Solutions and Electrical Solutions segments.

 

See Note 21 — Industry Segments and Geographic Area Information in the Notes to Consolidated Financial Statements and Item 1A. Risk Factors relating to manufacturing in and sourcing from foreign countries.

Customers

We have an extensive customer base of distributors, wholesalers, electric utilities, OEMs, electrical contractors, telecommunications companies and retail and hardware outlets. We are not dependent on a single customer, however, our top ten customers account for approximately 43% of our Net sales.

Raw Materials

Raw materials used in the manufacture of Hubbell products primarily include steel, aluminum, brass, copper, bronze, zinc, nickel, plastics, phenolics, elastomers and petrochemicals. Hubbell also purchases certain electrical and electronic components, including solenoids, lighting ballasts, printed circuit boards, integrated circuit chips and cord sets, from a number of suppliers. Hubbell is not materially dependent upon any one supplier for raw materials used in the manufacture of its products and equipment however the cost and supply of these materials may be affected by disruptions in availability of raw materials, components or sourced finished goods. See also Item 7A. Quantitative and Qualitative Disclosures about Market Risk. 

Patents

 

Hubbell has approximately 3,000 active United States and foreign patents covering a portion of its products, which expire at various times. While Hubbell deems these patents to be of value, it does not consider its business to be dependent upon patent protection. Hubbell also licenses products under patents owned by others, as necessary, and grants licenses under certain of its patents. 

Working Capital

 

Inventory, accounts receivable and accounts payable levels, payment terms and, where applicable, return policies are in accordance with the general practices of the electrical products industry and standard business procedures. See also Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. 

Backlog

 

Substantially all of the backlog existing at December 31, 2022 in the Electrical Solutions segment is expected to be shipped to customers in 2023. In the Utility Solutions segment, the backlog existing at December 31, 2022 includes backlog expected to be shipped during 2023, along with $320 million of backlog of contracts that span multiple years, primarily related to long-term contracts of the Aclara business to deliver and install meters and grid monitoring sensor technology. The backlog of orders believed to be firm at December 31, 2022 was $2,463.4 million compared to $1,848.0 million at December 31, 2021. Although this backlog is important, the majority of Hubbell’s revenues result from sales of inventoried products or products that have short periods of manufacture.

Competition

 

Hubbell experiences substantial competition in all categories of its business, but does not compete with the same companies in all of its product categories. The number and size of competitors vary considerably depending on the product line. Hubbell cannot specify with precision the number of competitors in each product category or their relative market position. However, some of its competitors are larger companies with substantial financial and other resources. Hubbell considers product performance, reliability, quality and technological innovation as important factors relevant to all areas of its business and considers its reputation as a manufacturer of quality products to be an important factor in its business. In addition, product price, service levels and other factors can affect Hubbell’s ability to compete.

Environment

 

The Company is subject to various federal, state and local government requirements relating to the protection of employee health and safety and the environment. The Company believes that, as a general matter, its policies, practices and procedures are properly designed to prevent unreasonable risk of environmental damage and personal injury to its employees and its customers’ employees and that the handling, manufacture, use and disposal of hazardous or toxic substances are in accordance with environmental laws and regulations.

 

Like other companies engaged in similar businesses, the Company has incurred or acquired through business combinations, remedial response and voluntary cleanup costs for site contamination, and is a party to product liability and other lawsuits and claims associated with environmental matters, including past production of products containing toxic substances. Additional lawsuits, claims and costs involving environmental matters are likely to continue to arise in the future. However, considering past experience and reserves, the Company does not anticipate that these matters will have a material adverse effect on earnings, capital expenditures, financial condition or competitive position. See also Item 1A. Risk Factors and Note 16 — Commitments and Contingencies in the Notes to Consolidated Financial Statements. 

Human Capital

Our commitment to developing our employees is one of four pillars that guide Hubbell as a company. We recruit, hire, and develop talent that meets and anticipates the ever-changing needs of our enterprise, while fostering an inclusive and diverse workplace. Hubbell provides market competitive compensation, health and well-being programs, and retirement benefits based on the countries and markets in which we operate to motivate market-leading performance.

As of December 31, 2022, Hubbell had approximately 16,300 salaried and hourly employees of whom approximately 9,800, or 60% are located in the United States. Approximately 1,800 of these U.S. employees are represented by 8 labor unions. Hubbell considers its labor relations to be satisfactory and regularly engages with its labor unions.

Hubbell is committed to fostering an environment that respects and encourages individual differences, diversity of thought, and talent. We strive to create a workplace where employees feel that their contributions are welcomed and valued, allowing them to fully engage their talents and training in their work, while generating personal satisfaction in their role within Hubbell. Hubbell has created a multi-year, enterprise-wide strategy dedicated to evolving our inclusive culture while addressing underrepresentation where it exists across our company. As of December 31, 2022, 32% of our employees identify as female, and within the United States, 30% identify as female and 45% are racially diverse.

Across the enterprise, there are a variety of ways we invest in our people to learn - on the job, in the classroom, through self-directed learning, or through leadership programs. We have expanded our learning management system (known as Hubbell University) to make new content and training available to our employees. The Company has also expanded leadership development programs to provide career development to employees at all levels and continues to expand its Campus Programs to foster a pipeline of early career talent at Hubbell.

The Company also fosters and encourages its employees to give back to their communities. The Company supports employees’ spirit of volunteerism in their communities throughout the year with its Volunteer Paid Time Off policy, which provides all employees with up to 8 hours of paid time off a year to volunteer with an eligible 501(c)(3) charity of their choice.

As a manufacturing company we focus on protecting the health and safety of our employees. We dedicate resources to track and monitor safety and recordable incidents using an enterprise-wide data management system. Through the Company’s myLife program, the Company provides comprehensive, competitive benefits that retain and support our employees supporting their health, wealth and peace of mind.

In October 2022, as a showing of appreciation to our employees continued excellence, the Company provided all employees globally with a Global Recharge Day. This paid day off provided all employees an opportunity to relax, refresh and recharge.

In 2022, Hubbell conducted an enterprise-wide employee survey, the Elevate Employee Experience Survey to better understand the voices of our employees worldwide. Elevate was the largest survey conducted by the Company and over 80% of Hubbell’s employees responded, providing insights that the Company is translating into action plans.

ITEM 1A    Risk Factors

 

Our business, operating results, financial condition, and cash flows may be affected by a number of factors including, but not limited to those set forth below. Any one of these factors could cause our actual results to vary materially from recent results or future anticipated results. See also Item 7. Management’s Discussion and Analysis — “Executive Overview of the Business” and “Results of Operations”.

 

COVID-19 Pandemic Risks

Our business and operations, and the operations of our suppliers, have been, and may in the future be adversely affected by epidemics or pandemics such as the COVID-19 pandemic outbreak. 

We may face risks related to health epidemics and pandemics or other outbreaks of communicable diseases.

A public health epidemic or pandemic, such as the COVID-19 pandemic, poses the risk that our employees, contractors, suppliers, customers and other business partners may be prevented from conducting business activities for an indefinite period of time, including due to shutdowns that may be requested or mandated by governmental authorities, or that such epidemic may otherwise interrupt or impair business activities.

The COVID-19 pandemic continues to cause disruption to the global economy, including in all of the regions in which we, our suppliers, distributors, business partners, and customers do business. We continue to monitor the pandemic, and while periodic local increases and decreases in COVID-19 cases are likely, generally the restrictions due to and in response to the pandemic continue to relax in most locations. However, the COVID-19 pandemic and efforts to manage it, including those by governmental authorities, have had, and could continue to have, an adverse effect on the economy and our business in many ways. This includes, but is not limited to, global supply chain shortages for materials and component parts used in our products and associated escalating prices. In addition to supply shortages, constrained transportation capacities have led to significant price increases in transportation costs. We expect to continue to be affected by supply chain issues due to factors largely beyond our control, including, a global shortage of semi-conductors, chips and components used in our products, a strain on raw materials and cost inflation, all of which could escalate in future quarters.

Although economic conditions have generally improved since the height of the pandemic, the strength of the economic recovery is uncertain and may vary across industries, customers and from country to country. The ultimate extent and robustness of any economic recovery from the impact of the pandemic imposes a significant degree of uncertainty and complexity, and may adversely affect our operations, customer demand and our costs of production. Failure of economic recovery to continue and adverse or weakening economic conditions may also result in deterioration in the collection of customer accounts receivable, as well as a reduction in sales.

Industry and Economic Risks

Inflation and other adverse conditions may adversely affect our business results of operations and financial condition.

Our operating results can be sensitive to changes in general economic conditions, inflation, economic slowdowns, stagflation and recessions. Our sales are subject to market conditions that may cause customer demand for our products to be volatile and unpredictable, particularly in our Electrical Solutions segment. Product demand can be affected by fluctuations in domestic and international economic conditions, as well as currency fluctuations, commodity costs, and a variety of other factors.

We have recently experienced significant inflationary pressure across much of our business. Global supply chains continue to struggle to keep up with increasing demand due to the lingering impact of the COVID-19 pandemic. The resulting supply chain issues and increased demand have also led to increased freight, labor and commodity costs. In addition, various factors, including the level of economic activity in China and the conflict in Ukraine, has added to the volatility in energy costs. We have had to take various pricing actions to cover the higher costs and protect our margin profile. There can be no assurance that we will be able to maintain our margins in response to further changes in inflationary pressures.

In addition, macroeconomic effects such as increases in interest rates and other measures taken by central banks and other policy makers could have a negative effect on overall economic activity that could reduce our customers’ demand for our products. Adverse changes in demand could impact our business, collection of accounts receivable and our expected cash flow generation from current and acquired businesses, which may adversely impact our financial condition and results of operations.

We operate in markets that are subject to competitive pressures that could affect selling prices or demand for our products.

 

We compete on the basis of product performance, quality, service and/or price. Competitors' behavior related to these areas could potentially have significant impacts on our financial results. Our competitive strategy is to design and manufacture high quality products at the lowest possible cost. Our strategy is to also increase selling prices to offset rising costs of raw materials and components. Competitive pricing pressures may not allow us to offset some or all of our increased costs through pricing actions. Alternatively, if raw material and component costs decline, the Company may not be able to maintain current pricing levels. Competition could also affect future selling prices or demand for our products which could have an adverse impact on our results of operations, financial condition and cash flows.

---

Volatility in currency exchange rates may adversely affect our financial condition, results of operations and cash flows.

 

Our international operations accounted for approximately 8% of our Net sales in 2022. We are exposed to the effects (both positive and negative) that fluctuating exchange rates have on translating the financial statements of our international operations, most of which are denominated in local currencies, into the U.S. dollar. Fluctuations in exchange rates may affect product demand and reported profits in our international operations. In addition, currency fluctuations may affect the prices we pay suppliers for materials used in our products, along with other local costs incurred in foreign countries for foreign entities with U.S. dollar functional currency. As a result, fluctuating exchange rates may adversely impact our results of operations and cash flows.

Uncertainty about the future of the London Interbank Offer Rate ("LIBOR") may adversely affect our business and financial results.

Our 2021 Credit Facility uses LIBOR as a reference rate, such that the interest due pursuant to such borrowings may be calculated using LIBOR plus an applicable margin (determined by reference to a ratings based grid) or the alternate base rate. In March 2021, the UK’s Financial Conduct Authority, which regulates LIBOR, announced that for most tenors of the USD LIBOR, rates would cease to be published after June 30, 2023, and one-week and two-month LIBOR ceased being published as of December 31, 2021. It is not possible to predict the effect of this announcement, including what alternative reference rates may replace LIBOR in use going forward, and how LIBOR will be determined for purposes of loans, securities and derivative instruments currently referencing it when it ceases to exist. Once LIBOR is no longer available, if lenders have increased costs due to such changes, we may suffer from potential increases in interest rates on our floating rate debt. These uncertainties or their resolution also could negatively impact our funding costs, loan and other asset values, asset-liability management strategies, and other aspects of our business and financial results.

Business and Operational Risks

  

Our ability to effectively develop and introduce new products could adversely affect our ability to compete.

 

New product introductions and enhancement of existing products and services are key to the Company’s competitive strategy. The success of new product introductions is dependent on a number of factors, including, but not limited to, timely and successful development of new products, including software development, market acceptance of these products and the Company’s ability to manage the risks associated with these introductions. These risks include development and production capabilities, management of inventory levels to support anticipated demand, the risk that new products may have quality defects in the early stages of introduction, and obsolescence risk of existing products. The Company cannot predict with certainty the ultimate impact new product introductions could have on our results of operations, financial condition or cash flows.

We manufacture and source products and materials from various countries throughout the world. A disruption in the availability, price or quality of these products or materials could adversely affect our operating results.

Our business is subject to risks associated with global manufacturing and sourcing. We use a variety of raw materials in the production of our products including steel, aluminum, brass, copper, bronze, zinc, nickel, plastics, phenolics, elastomers and petrochemicals. We also purchase certain electrical and electronic components, including solenoids, lighting ballasts, printed circuit boards, integrated circuit chips and cord sets from a number of suppliers. Significant shortages in the availability of these materials or significant price increases could increase our operating costs and adversely impact the competitive positions of our products, which could adversely impact our results of operations. See also Risk Factor, “Significant developments from the recent and potential changes in U.S. trade policies could have a material adverse effect on us.”

 

We rely on materials, components and finished goods that are sourced from or manufactured in foreign countries including Mexico, China, and other international countries. Political instability in any country where we do business could have an adverse impact on our results of operations.

 

We rely on our suppliers to produce high quality materials, components and finished goods according to our specifications, including timely delivery. There is a risk that products may not meet our quality control procedure specifications which could adversely affect our ability to ship quality products to our customers on a timely basis and, could adversely affect our results of operations.

We may be required to recognize impairment charges for our goodwill and other intangible assets.

 

As of December 31, 2022, the net carrying value of our goodwill and other intangible assets totaled approximately $2,640.4 million. As required by generally accepted accounting principles, we periodically assess these assets to determine if they are impaired. Impairment of intangible assets may be triggered by developments both within and outside the Company’s control. Deteriorating economic conditions, technological changes, disruptions to our business, inability to effectively integrate acquired businesses, unexpected significant changes or planned changes in use of the assets, intensified competition, divestitures, market capitalization declines and other factors may impair our goodwill and other intangible assets. Any charges relating to such impairments could adversely affect our results of operations in the periods an impairment is recognized.

HUBBELL INCORPORATED - Form 10-K			9

---

We engage in acquisitions and strategic investments and may encounter difficulty in obtaining appropriate acquisitions and in integrating these businesses.

 

Part of the Company’s growth strategy involves acquisitions. We have pursued and will continue to seek acquisitions and other strategic investments to complement and expand our existing businesses. The rate and extent to which acquisitions become available may affect our growth rate. The success of these transactions will depend on our ability to integrate these businesses into our operations and realize the planned synergies. We may encounter difficulties in integrating acquisitions into our operations and in managing strategic investments and foreign acquisitions and joint ventures may also present additional risk related to the integration of operations across different cultures and languages. Failure to effectively complete or manage acquisitions may adversely affect our existing businesses as well as our results of operations, financial condition and cash flows.

We may not be able to successfully implement initiatives, including our restructuring activities that improve productivity and streamline operations to control or reduce costs.

 

Achieving our long-term profitability goals depends significantly on our ability to control or reduce our operating costs. Because many of our costs are affected by factors completely, or substantially outside our control, we generally must seek to control or reduce costs through productivity initiatives. If we are not able to identify and implement initiatives that control or reduce costs and increase operating efficiency, or if the cost savings initiatives we have implemented to date do not generate expected cost savings, our financial results could be adversely affected. Our efforts to control or reduce costs may include restructuring activities involving workforce reductions, facility consolidations and other cost reduction initiatives. If we do not successfully manage our current restructuring activities, or any other restructuring activities that we may undertake in the future, expected efficiencies and benefits may be delayed or not realized, and our operations and business could be disrupted, which could have an adverse effect on our results of operations, financial condition and cash flows.

We are subject to risks surrounding our information technology systems failures, network disruptions, breaches in data security and compliance with data privacy laws or regulations.

 

We are highly dependent on various software and information technology systems to record and process operational, human resources and financial transactions. The proper functioning of Hubbell’s information technology systems is critical to the successful operation of our business. Our information technology systems are susceptible to cyber threats, malware, phishing attacks, break-ins and similar events, breaches of physical security or tampering and manipulation of these systems by employees or unauthorized third parties. Information security risks also exist with respect to the use of portable electronic devices, such as smartphones and laptops, which are particularly vulnerable to loss and theft. Hubbell may also be subject to disruptions of any of our systems and our vendor's systems arising from events that are wholly or partially beyond our control, such as natural disasters, acts of terrorism, cyber-attacks, computer viruses, and electrical/telecommunications outages or failures. All of these risks are also applicable where Hubbell relies on outside vendors to provide services, which may operate in an online, or “cloud,” environment. A failure of our information technology systems could adversely affect our ability to process orders, maintain proper levels of inventory, collect accounts receivable and pay expenses; all of which could have an adverse effect on our results of operations, financial condition and cash flows. In addition, security breaches could result in unauthorized disclosure of confidential information that may result in financial or reputational damage to the Company, as well as expose the Company to litigation and regulatory enforcement actions.

Hubbell also provides customers with solutions that include software components that allow for the control and/or the communication of data from those solutions to Hubbell or customer systems. In addition to the risks noted above, there are other risks associated with these solutions. For example, control and/or data from these solutions may be integral to a customer's operations. A failure of our technology to operate as designed or as a result of cyber threats could impact those operations, including by loss or destruction of data. Likewise, a customer’s failure to properly configure its own network are outside of the Company’s control and could result in a failure in functionality or security of our technology.

Hubbell is also subject to an increasing number of evolving data privacy and security laws and regulations that impose requirements on the Company and our technology prior to certain use or transfer, storing, processing, disclosure, and protection of data and prior to sale or use of certain technologies. Failure to comply with such laws and regulations could result in the imposition of fines, penalties and other costs. For example, the European Union’s implementation of the General Data Protection Regulation in 2018, the European Union’s pending ePrivacy Regulation and the implementation of the ePrivacy Directive by the various European Union member states, and California’s implementation of its Consumer Privacy Act of 2018 and Connected Device Privacy Act of 2018, as well as data privacy statutes implemented by other states, could all disrupt our ability to sell products and solutions or use and transfer data because such activities may not be in compliance with applicable law in certain jurisdictions.

 

We have continued to work on improving our utilization of our enterprise resource planning system, expanding standardization of business processes and performing implementations at our remaining businesses, as well as acquired businesses. We expect to incur additional costs related to future implementations, process reengineering efforts as well as enhancements and upgrades to the system. These system modifications and implementations could result in operating inefficiencies which could adversely impact our operating results and/or our ability to perform necessary business transactions.

System failures, ineffective system implementation or disruptions, failure to comply with data privacy and security laws or regulations, IT system risk arising from the Company's acquisition activity or the compromise of security with respect to internal or external systems or portable electronic devices could damage the Company’s systems or infrastructure, subject us to liability claims, or regulatory fines, penalties, or intervention, harm our reputation, interrupt our operations, disrupt customer operations, and adversely affect the Company’s internal control over financial reporting, business, financial condition, results of operations, or cash flows.

Our ability to access capital markets or failure to maintain our credit ratings may adversely affect our business.

 

Our ability to invest in our business and make strategic acquisitions may require access to the capital markets. If general economic and capital market conditions deteriorate significantly, it could impact our ability to access capital. Failure to maintain our credit ratings could also impact our ability to access credit markets and could increase our cost of borrowing. The capital and credit markets could deteriorate and market conditions could make it more difficult for us to access capital to finance our investments and acquisitions, which could adversely affect our results of operations, financial condition and cash flows.

Deterioration in the credit quality of our customers could have a material adverse effect on our operating results and financial condition.

 

We have an extensive customer base of distributors, wholesalers, electric utilities, OEMs, electrical contractors, telecommunications companies and retail and hardware outlets. We are not dependent on a single customer, however, our top ten customers account for approximately 43% of our Net sales. Deterioration in the credit quality of several major customers could adversely affect our results of operations, financial condition and cash flows.

We have outstanding indebtedness; our indebtedness will increase if we incur additional indebtedness in the future and do not retire existing indebtedness.

We have outstanding indebtedness and other financial obligations and significant unused borrowing capacity. Our indebtedness level and related debt service obligations could have negative consequences, including (i) requiring us to dedicate significant cash flow from operations to the payment of principal and interest on our indebtedness, which would reduce the funds we have available for other purposes, (ii) reducing our flexibility in planning for or reacting to changes in our business and market conditions and (iii) exposing us to interest rate risk since a portion of our debt obligations are at variable rates.

We may incur significantly more indebtedness in the future. If we add new indebtedness and do not retire existing indebtedness, the risks described above could increase.

If the underlying investments of our defined benefit plans do not perform as expected, we may have to make additional contributions to these plans.

 

We sponsor certain pension and other postretirement defined benefit plans. The performance of the financial markets and interest rates impact these plan expenses and funding obligations. Significant changes in market interest rates, investment losses on plan assets and reductions in discount rates may increase our funding obligations and could adversely impact our results of operations, cash flows, and financial condition. Furthermore, there can be no assurance that the value of the defined benefit plan assets will be sufficient to meet future funding requirements.

Legal, Tax and Regulatory Risks

Changes in tax law relating to multinational corporations could adversely affect our tax position.

Government agencies, and the Organisation for Economic Co-operation and Development (“OECD”) have focused on issues related to the taxation of multinational corporations. One example is in the area of “base erosion and profit shifting,” for which the OECD has released several components of its comprehensive plan that have been adopted and expanded by many taxing authorities to address perceived tax abuse and inconsistencies between tax jurisdictions. As a result, the tax laws in countries in which we do business could change on a prospective or retroactive basis, and any such changes could adversely affect our business and financial statements.

Because tax laws and regulations are subject to interpretation and uncertainty, tax payments may ultimately differ from amounts currently recorded by the Company.

 

We are subject to income taxes as well as non-income based taxes, in both the United States and numerous foreign jurisdictions. The determination of the Company's worldwide provision for income taxes and other tax liabilities requires judgment and is based on diverse legislative and regulatory structures that exist in the various jurisdictions where the company operates. The ultimate tax outcome may differ from the amounts recorded in the Company's financial statements and may adversely affect the Company's financial results for the period when such determination is made. We are subject to ongoing tax audits in various jurisdictions. Tax authorities may disagree with certain positions we have taken and assess additional taxes. We regularly assess the likely outcomes of these audits in order to determine the appropriateness of our tax provisions. However, there can be no assurance that we will accurately predict the outcomes of these audits, and the future outcomes of these audits could adversely affect our results of operations, financial condition and cash flows.

Significant developments from the recent and potential changes in U.S. trade policies could have a material adverse effect on us.

Over the last five years, the U.S. government has announced and, in some cases, implemented a new approach to trade policy, including renegotiating, or potentially terminating, certain existing bilateral or multi-lateral trade agreements, such as the North American Free Trade Agreement ("NAFTA"), which was replaced by the U.S.-Mexico-Canada Agreement, on July 1, 2020, and proposed trade agreements, like the Trans-Pacific Partnership ("TPP"), from which the United States has formally withdrawn, as well as implementing the imposition of additional tariffs on certain foreign goods, including finished products and raw materials such as steel and aluminum. Changes in the U.S. trade policy, U.S. social, political, regulatory and economic conditions or in laws and policies governing foreign trade, manufacturing, development and investment in the territories and countries where we currently manufacture and sell products, and any resulting negative sentiments towards the United States as a result of such changes, could have an adverse effect on our business. In addition, we cannot predict what changes to trade policy will be made by the current presidential administration and Congress, including whether existing tariff policies will be maintained or modified or whether the entry into new bilateral or multilateral trade agreements will occur, nor can we predict the effects that any conceivable changes would have on our business.

 

We rely on materials, components and finished goods, such as steel and aluminum, that are sourced from or manufactured in foreign countries, including China and Mexico. Import tariffs and potential import tariffs have resulted or may result in increased prices for these imported goods and materials and, in some cases, may result or have resulted in price increases for domestically sourced goods and materials. Changes in U.S. trade policy have resulted and could result in additional reactions from U.S. trading partners, including adopting responsive trade policies making it more difficult or costly for us to export our products or import goods and materials from those countries. These measures could also result in increased costs for goods imported into the U.S. or may cause us to adjust our worldwide supply chain. Either of these could require us to increase prices to our customers which may reduce demand, or, if we are unable to increase prices, result in lowering our margin on products sold.

In recent years, various countries, and regions, including, without limitation, China, Mexico, Canada and Europe, have announced plans or intentions to impose or have imposed tariffs on a wide range of U.S. products in retaliation for new U.S. tariffs. These actions could, in turn, result in additional tariffs being adopted by the U.S. These conditions and future actions could have a significant adverse effect on world trade and the world economy. To the extent that trade tariffs and other restrictions imposed by the United States increase the price of, or limit the amount of, raw materials and finished goods imported into the United States, the costs of our raw materials may be adversely affected and the demand from our customers for products and services may be diminished, which could adversely affect our revenues and profitability.

12			HUBBELL INCORPORATED - Form 10-K

---

We cannot predict future trade policy or the terms of any renegotiated trade agreements and their impacts on our business. The adoption and expansion of trade restrictions, the occurrence of a trade war, or other governmental action related to tariffs or trade agreements or policies has the potential to adversely impact demand for our products, our costs, our customers, our suppliers, and the U.S. economy, which in turn could adversely impact our business, financial condition and results of operations.

Our business and results of operations may be materially adversely effected by compliance with import and export laws.

We must comply with various laws and regulations relating to the import and export of products, services and technology from the U.S. and other countries having jurisdiction over our operations, which may affect our transactions with certain customers, business partners and other persons. In certain circumstances, export control and economic sanctions regulations may prohibit the export of certain products, services and technologies and in other circumstances, we may be required to obtain an export license before exporting a controlled item. The length of time required by the licensing processes can vary, potentially delaying the shipment of products or performance of services and the recognition of the corresponding revenue. In addition, failure to comply with any of these regulations could result in civil and criminal, monetary and non-monetary penalties, disruptions to our business, limitations on our ability to import and export products and services and damage to our reputation. Moreover, any changes in export control or sanctions regulations may further restrict the export of our products or services, and the possibility of such changes requires constant monitoring to ensure we remain compliant. Any restrictions on the export of our products or product lines could have a material adverse effect on our competitive position, results of operations, cash flows or financial condition.

The uncertainty surrounding the implementation and effect of Brexit and related negative developments in the European Union and elsewhere could adversely affect our business, financial condition and results of operations.

In 2020, the United Kingdom exited the European Union (“EU”) (commonly referred to as “Brexit”). The long-term effects of Brexit, including the UK's relationship with the EU and other countries, including the U.S., remains unclear. We conduct business in both the UK and EU and shipments from our UK subsidiaries represented 3% of our total Net sales in both 2022 and 2021. Brexit could adversely affect European or worldwide political, regulatory, economic or market conditions and could contribute to instability in political institutions and regulatory agencies. Brexit could also have the effect of disrupting the free movement of goods, services, and people between the UK, the EU and elsewhere. There can be no assurance that any or all of these events, or others that we cannot anticipate at this time, will not have a material adverse effect on our business, financial condition and results of operations.

We could incur significant and/or unexpected costs in our efforts to successfully avoid, manage, defend and litigate intellectual property matters.

 

The Company relies on certain patents, trademarks, copyrights, trade secrets and other intellectual property of which the Company cannot be certain that others have not and will not infringe upon. Intellectual property litigation could be costly and time consuming and the Company could incur significant legal expenses pursuing these claims against others.

 

From time to time, we receive notices from third parties alleging intellectual property infringement. Any dispute or litigation involving intellectual property could be costly and time-consuming due to the complexity and the uncertainty of intellectual property litigation. Our intellectual property portfolio may not be useful in asserting a counterclaim, or negotiating a license, in response to a claim of infringement or misappropriation. In addition, as a result of such claims, the Company may lose its rights to utilize critical technology or may be required to pay substantial damages or license fees with respect to the infringed rights or be required to redesign our products at a substantial cost, any of which could negatively impact our operating results. Even if we successfully defend against claims of infringement, we may incur significant costs that could adversely affect our results of operations, financial condition and cash flow. See Item 3 “Legal Proceedings” for a discussion of our legal proceedings.

We are subject to litigation and environmental regulations that may adversely impact our operating results.

We are a party to a number of legal proceedings and claims, including those involving product liability, intellectual property and environmental matters, which could be significant. It is not possible to predict with certainty the outcome of every claim and lawsuit. In the future, we could incur judgments or enter into settlements of lawsuits and claims that could have a materially adverse effect on our results of operations, cash flows, and financial condition. In addition, we maintain insurance coverage with respect to certain claims, which insurance may not provide adequate coverage against such claims. We establish reserves based on our assessment of contingencies, including contingencies related to legal claims asserted against us. Subsequent developments in legal proceedings may affect our assessment and estimates of the loss contingency recorded as a reserve and require us to make additional payments, which could have a materially adverse effect on our results of operations, financial condition and cash flow.

We are also subject to various laws and regulations relating to environmental protection and the discharge of materials into the environment, and we could incur substantial costs as a result of the noncompliance with or liability for clean up or other costs or damages under environmental laws. In addition, we could be affected by future laws or regulations, including those imposed in response to climate change concerns. Environmental laws and regulations have generally become stricter in recent years. Compliance with any future laws and regulations could result in a materially adverse effect on our business and financial results. See Item 3 “Legal Proceedings” for a discussion of our legal proceedings.

Our reputation and our ability to conduct business may be impaired by improper conduct by any of our employees, agents or business partners.

 

We cannot provide absolute assurance that our internal controls and compliance systems will always protect us from acts committed by our employees, agents or business partners that would violate U.S. and/or non-U.S. laws, including the laws governing payments to government officials, bribery, fraud, anti-kickback and false claims rules, competition, export and import compliance, money laundering and data privacy. In particular, the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act, and similar anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments to government officials for the purpose of obtaining or retaining business, and we operate in parts of the world that have experienced governmental corruption to some degree. Despite meaningful measures that we undertake to facilitate lawful conduct, which include training and internal control policies, these measures may not always prevent reckless or criminal acts by our employees or agents. Any such improper actions could damage our reputation and subject us to civil or criminal investigation in the United States and in other jurisdictions, could lead to substantial civil and criminal, monetary and non-monetary penalties and could cause us to incur significant legal and investigative fees.

Regulations related to conflict-free minerals may cause us to incur additional expenses and may create challenges with our customers.

 

The Dodd-Frank Wall Street Reform and Consumer Protection Act contains provisions to improve transparency and accountability regarding the use of “conflict” minerals mined from the Democratic Republic of Congo and adjoining countries (“DRC”). The SEC has established annual disclosure and reporting requirements for those companies who use “conflict” minerals sourced from the DRC in their products. These new requirements could limit the pool of suppliers who can provide conflict-free minerals and as a result, we cannot ensure that we will be able to obtain these conflict-free minerals at competitive prices. Compliance with these new requirements may also increase our costs. In addition, we may face challenges with our customers if we are unable to sufficiently verify the origins of the minerals used in our products.

General Risk Factors

We face the potential harms of natural disasters, terrorism, acts of war, international conflicts or other disruptions to our operations.

Natural disasters, the economic uncertainty resulting from the spread of global pandemics, acts or threats of war or terrorism, international conflicts, and the actions taken by the United States and other governments in response to such events could cause damage to or disrupt our business operations, our suppliers or our customers, and could create political or economic instability, any of which could have an adverse effect on our business. For example, increases in energy demand and supply disruptions caused by the conflict in Ukraine have resulted in significantly higher energy prices, particularly in Europe. Persistent high energy prices and the potential for further supply disruptions, may have an adverse impact on our business. Although it is not possible to predict such events or their consequences, these events could decrease demand for our products, make it difficult or impossible for us to deliver products, or disrupt our supply chain.

Global economic uncertainty could adversely affect us.

 

During periods of prolonged slow growth, or a downturn in conditions in the worldwide or domestic economies, we could experience reduced orders, payment delays, supply chain disruptions or other factors caused by economic challenges faced by our customers, prospective customers and suppliers. Depending upon their severity and duration, these conditions could have an adverse impact on our results of operations, financial condition and cash flows.

Our success depends on attracting and retaining qualified personnel.

 

Our ability to sustain and grow our business requires us to hire, retain and develop a highly skilled and diverse management team and workforce. Failure to ensure that we have the depth and breadth of personnel with the necessary skill set and experience, or the loss of key employees, could impede our ability to deliver our growth objectives and execute our strategy.

ITEM 7    Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with the consolidated financial statements and accompanying notes included in Part II, Item 8 of this Annual Report on Form 10-K. This section of this Form 10-K generally discusses 2022 and 2021 items and year-to-year comparisons between 2022 and 2021. Discussions of 2020 items and year-to-year comparisons between 2021 and 2020 are not included in this Form 10-K and can be found in "Management's Discussion and Analysis of Financial Condition and Results of Operations" in Part II, Item 7 of the Company's Annual Report on Form-10-K for the fiscal year ended December 31, 2021 filed with the Securities and Exchange Commission on February 11, 2022.

Executive Overview of the Business

 

Hubbell is a global manufacturer of quality electrical products and utility solutions for a broad range of customer and end market applications. We provide utility and electrical solutions that enable our customers to operate critical infrastructure reliably and efficiently, and we empower and energize communities through innovative solutions supporting energy infrastructure In Front of the Meter, on The Edge, and Behind the Meter. In Front of the Meter is where utilities transmit and distribute energy to their customers. The Edge connects utilities with owner/operators and allows energy and data to be distributed back and forth. Behind the Meter is where owners and operators of buildings, industrial facilities and other critical infrastructure consume energy. Products are either sourced complete, manufactured or assembled by subsidiaries in the United States, Canada, Puerto Rico, Mexico, China, the UK, Brazil, Australia, Spain and Ireland. The Company also participates in joint ventures in Hong Kong and the Philippines, and maintains offices in Singapore, Italy, China, India, Mexico, South Korea, Chile, and countries in the Middle East. The Company employed approximately 16,300 individuals worldwide as of December 31, 2022.

Our reporting segments consist of the Utility Solutions segment, that has leading position in Front of the Meter and at The Edge and the Electrical Solutions segment that is positioned Behind the Meter.

 

Our long-term strategy is to serve our customers with reliable and innovative electrical and related infrastructure solutions with desired brands and high-quality service, delivered through a competitive cost structure; to complement organic revenue growth with acquisitions that enhance its product offerings; and to allocate capital effectively to create shareholder value.

Our strategy to complement organic revenue growth with acquisitions is focused on acquiring assets that extend our capabilities, expand our product offerings, and present opportunities to compete in core, adjacent or complementary markets. Our acquisition strategy also provides the opportunity to advance our revenue growth objectives during periods of weakness or inconsistency in our end-markets.

Our strategy to deliver products through a competitive cost structure has resulted in past and ongoing restructuring and related activities. Our restructuring and related efforts include the consolidation of manufacturing and distribution facilities, and workforce actions, as well as streamlining and consolidating our back-office functions. The primary objectives of our restructuring and related activities are to optimize our manufacturing footprint, cost structure, effectiveness and efficiency of our workforce.

Productivity improvement also continues to be a key area of focus for the Company and efforts to drive productivity complement our restructuring and related activities to minimize the impact of rising material costs and other administrative cost inflation. Because material costs are approximately two thirds of our cost of goods sold, volatility in this area can significantly impact profitability. Our goal is to have pricing and productivity programs that offset material and other inflationary cost increases as well as pay for investments in key growth areas.

Productivity programs affect virtually all functional areas within the Company by reducing or eliminating waste and improving processes. We continue to expand our efforts related to global product and component sourcing and supplier cost reduction programs. Value engineering efforts, product transfers and the use of lean process improvement techniques are expected to continue to increase manufacturing efficiency. In addition, we continue to build upon the benefits of our enterprise resource planning system across all functions.

Our sales are also subject to market conditions that may cause customer demand for our products to be volatile and unpredictable, particularly in our Electrical Solutions segment. Product demand can be affected by fluctuations in domestic and international economic conditions, as well as currency fluctuations, commodity costs, and a variety of other factors. We have recently experienced significant inflationary pressure across much of our business. We have had to take various pricing actions to cover the higher costs and protect our margin profile. Because we expect inflation to remain a factor for the foreseeable future, we expect to continue these pricing actions subject, however, to demand and market conditions. Accordingly, there can be no assurance that we will be able to maintain our margins in response to the continuation or worsening of inflationary pressures. In addition, macroeconomic effects such as increases in interest rates and other measures taken by central banks and other policy makers could have a negative effect on overall economic activity that could reduce our customers’ demand for our products.

Discontinued Operations

On February 1, 2022, the Company completed the sale of the Commercial and Industrial Lighting business (the "C&I Lighting business") to GE Current, a Daintree Company. The disposal of the C&I Lighting business met the criteria set forth in ASC 205-20 to be presented as a discontinued operation. The C&I Lighting businesses' results of operations and the related cash flows have been reclassified to income from discontinued operations in the Consolidated Statements of Income and cash flows from discontinued operations in the Consolidated Statement of Cash Flows, respectively, for all periods presented. For additional information regarding this transaction and its effect on our financial reporting, see Note 2 – Discontinued Operations, in the accompanying Consolidated Financial Statements, which note is incorporated herein by reference.

Impact of the COVID-19 Pandemic

Notwithstanding a general improvement in conditions and reduction of adverse effects from the COVID-19 pandemic that began in the first quarter of 2020, as of December 31, 2022 there continues to be significant uncertainty around the scope, severity, and duration of the pandemic, as well as the breadth and duration of business disruptions related to it and the overall impact on the U.S., global economies, and our operating results in future periods.

Additionally, as economies have re-opened, global supply chains have struggled to keep up with increasing demand, and the resulting supply chain disruptions have, in certain cases, affected our ability to ship finished products in a timely manner. These supply chain disruptions and the increase in demand have also led to increased freight, labor and commodity costs, which are expected to persist into 2023.

Results of Operations

Our operations are classified into two reportable segments: Utility Solutions and Electrical Solutions. For a complete description of the Company’s segments, see Part I, Item 1 of this Annual Report on Form 10-K. Within these segments, Hubbell serves customers in five primary end markets: utility T&D components, utility communications and controls, non-residential, residential, and industrial.

In 2022, Net sales increased by 18.0% or $754 million and organic Net sales(1) increased by 17.5% or $732 million on favorable price realization along with higher volumes, as further discussed in segment results below. Operating margin increased in 2022, by 160 basis points and adjusted operating margin(1) increased by 140 basis points, driven by price realization that exceeded material cost inflation, higher unit volume and savings from our restructuring and related actions, partially offset by higher freight, logistics and manufacturing costs, as well as other inflationary cost increases in excess of productivity and increased investment in our business. Net income from Continuing Operations attributable to Hubbell increased by 40.1% in 2022 compared to the prior year and diluted earnings per share from Continuing Operations increased by 41.6%. Adjusted net income from continuing operations attributable to Hubbell(1) increased by 30.3% in 2022 compared to the prior year and adjusted diluted earnings per share from continuing operations(1) increased by 31.9% in 2022.

Free cash flow(2) was higher in 2022 at $506.9 million as compared to $423.5 million in the prior year. In 2022 we paid $229.6 million in shareholder dividends, an increase of 5.9% as compared to the prior year, while also repurchasing $182 million of shares in 2022.

(1) Organic Net sales, adjusted operating margin, adjusted net income from continuing operations attributable to Hubbell and adjusted diluted earnings per share from continuing operations are non-GAAP financial measures. See "Adjusted Operating Measures" below for a reconciliation to the comparable GAAP financial measures.

(2) Free cash flow is a non-GAAP financial measure. See "Adjusted Operating Measures" and "Financial Condition, Liquidity and Capital Resources - Cash Flow" below for a reconciliation to the comparable GAAP financial measure.

Adjusted Operating Measures

In the following discussion of results of operations, we refer to "adjusted" operating measures. We believe those adjusted measures, which exclude the impact of certain costs, gains and losses, may provide investors with useful information regarding our underlying performance from period to period and allow investors to understand our results of operations without regard to items we do not consider a component of our core operating performance.

Adjusted operating measures exclude amortization of all intangible assets associated with our business acquisitions, including inventory step-up amortization associated with those acquisitions. The intangible assets associated with our business acquisitions arise from the allocation of the purchase price using the acquisition method of accounting in accordance with Accounting Standards Codification 805, “Business Combinations.” These assets consist primarily of customer relationships, developed technology, trademarks and tradenames, and patents, as reported in Note 7 – Goodwill and Other Intangible Assets, under the heading “Total Definite-Lived Intangibles" within the Notes to Consolidated Financial Statements.

The Company believes that the exclusion of these non-cash expenses (i) enhances management’s and investors’ ability to analyze underlying business performance, (ii) facilitates comparisons of our financial results over multiple periods, and (iii) provides more relevant comparisons of our results with the results of other companies as the amortization expense associated with these assets may fluctuate significantly from period to period based on the timing, size, nature, and number of acquisitions. Although we exclude amortization of these acquired intangible assets and inventory step-up from our non-GAAP results, we believe that it is important for investors to understand that revenue generated, in part, from such intangibles is included within revenue in determining adjusted net income from continuing operations.

Adjusted operating measures also exclude the following:

•2022 - Pension settlement charges of $7.0 million.

•2021 - A $16.8 million pre-tax loss on the early extinguishment of long-term debt from the redemption of all of the Company's outstanding 3.625% Senior Notes due 2022 in the aggregate principal amount of $300 million and a $6.9 million loss on the disposal of a business.

•Income tax effects of the above adjustments which are calculated using the statutory tax rate, taking into consideration the nature of the item and the relevant taxing jurisdiction, unless otherwise noted.

These items are reported in Total other expense (below Operating income) in the Consolidated Statement of Income. The Company excludes these non-core items because we believe it enhances management's and investors' ability to analyze underlying business performance and facilitates comparisons of our financial results over multiple periods. Refer to the reconciliation of non-GAAP measures presented below, Note 4 – Business Acquisitions and Dispositions, Note 12 – Retirement Benefits, and Note 13 – Debt in the Notes to Consolidated Financial Statements, for additional information.

Organic Net sales, a non-GAAP measure, represents Net sales according to U.S. GAAP, less Net sales from acquisitions and divestitures during the first twelve months of ownership or divestiture, respectively, less the effect of fluctuations in Net sales from foreign currency exchange. The period-over-period effect of fluctuations in Net sales from foreign currency exchange is calculated as the difference between local currency Net sales of the prior period translated at the current period exchange rate as compared to the same local currency Net sales translated at the prior period exchange rate. We believe this measure provides management and investors with a more complete understanding of the underlying operating results and trends of established, ongoing operations by excluding the effect of acquisitions, dispositions and foreign currency as these activities can obscure underlying trends. When comparing Net sales growth between periods excluding the effects of acquisitions, business dispositions and currency exchange rates, those effects are different when comparing results for different periods. For example, because Net sales from acquisitions are considered inorganic from the date we complete an acquisition through the end of the first year following the acquisition, Net sales from such acquisition are reflected as organic Net sales thereafter.

There are limitations to the use of non-GAAP measures. Non-GAAP measures do not present complete financial results. We compensate for this limitation by providing a reconciliation between our non-GAAP financial measures and the respective most directly comparable financial measure calculated and presented in accordance with GAAP. Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies’ non-GAAP financial measures having the same or similar names. These financial measures should not be considered in isolation from, as substitutes for, or alternative measures of, reported GAAP financial results, and should be viewed in conjunction with the most comparable GAAP financial measures and the provided reconciliations thereto. We believe, however, that these non-GAAP financial measures, when viewed together with our GAAP results and related reconciliations, provide a more complete understanding of our business. We strongly encourage investors to review our consolidated financial statements and publicly filed reports in their entirety and not rely on any single financial measure.

2022 Compared to 2021

Net Sales

Net sales of $4,947.9 million in 2022 increased by $753.8 million, or 18.0%, compared to 2021 driven by Organic net sales growth of 17.5% due to favorable price realization along with higher unit volume. Net sales also increased by 1.0% from acquisitions, partially offset by 0.4% from foreign exchange.

Cost of Goods Sold

Cost of goods sold was 70.3% of Net sales in 2022 as compared to 72.5% in 2021. The decrease was primarily driven by favorable price realization that was in excess of material cost inflation and higher unit volume, partially offset by higher freight, logistics and manufacturing costs, as well as other inflationary cost increases in excess of productivity and higher investments in our business.

Gross Profit

The gross profit margin in 2022 was 29.7% of Net sales as compared to 27.5% in 2021. Excluding amortization of acquisition-related intangible assets, the adjusted gross profit margin was 30.4% in 2022 as compared to 28.1% in 2021. The increase in gross profit and adjusted gross profit margin was primarily driven by favorable price realization that was in excess of material cost inflation and higher unit volume, partially offset by higher freight, logistics and manufacturing costs, as well as other inflationary cost increases in excess of productivity and higher investments in our business.

Selling & Administrative Expenses

S&A expense in 2022 was $762.5 million and increased by $143.3 million compared to the prior year period. S&A expense as a percentage of Net sales increased by 60 basis points to 15.4% in 2022. Excluding amortization of acquisition-related intangible assets, adjusted S&A expense as a percentage of Net sales increased by 80 basis points to 14.4% in 2022. The increase in S&A expense and adjusted S&A expense as a percentage of Net sales is primarily due to the impact of higher personnel cost and other cost inflation that was partially offset by a benefit from an increase in Net sales volume.

Operating Income

Operating income in 2022 was $709.1 million, an increase of 33.2% compared to 2021, and operating margin increased by 160 basis points to 14.3%. Excluding amortization of acquisition-related intangible assets, adjusted operating income increased by 29.1% in 2022 to $787.7 million and adjusted operating margin increased by 140 basis points to 15.9% in 2022. The increase in operating margin and adjusted operating margin is primarily due to favorable price realization that was in excess of material cost inflation and higher unit volume, partially offset by higher freight, logistics and manufacturing costs, as well as other inflationary cost increases in excess of productivity and higher investments in our business.

Total Other Expense

Total other expense decreased by $20.9 million in 2022 to $52.1 million compared to the prior year, primarily due to a $16.8 million pre-tax loss on the early extinguishment of long-term debt recognized in the second quarter of 2021 from the redemption of the Company's $300 million long-term notes, which were scheduled to mature in 2022, and by a $5.1 million reduction in interest expense.

Income Taxes

The effective tax rate was 21.3% in 2022 as compared to 19.2% in 2021. The increase in the effective tax rate is primarily due to favorable tax effects from stock-based compensation in 2021 that were higher as compared to 2022, as well as increased earnings in higher taxed jurisdictions in 2022.

Net Income From Continuing Operations Attributable to Hubbell and Earnings Per Diluted Share From Continuing Operations

Net income from continuing operations attributable to Hubbell was $511.3 million in 2022 and increased 40.1% as compared to 2021. Adjusted net income from continuing operations attributable to Hubbell was $575.5 million in 2022 and increased 30.3% as compared to 2021. The increase in net income from continuing operations and adjusted net income from continuing operations is primarily the result of higher operating income, driven by higher Net sales, and operation margin expansion, partially offset by an increase in the effective tax rate. As a result, earnings per diluted share from continuing operations in 2022 increased 41.6% compared to 2021. Adjusted earnings per diluted share from continuing operations in 2022 increased 31.9% as compared to 2021.

Income From Discontinued Operations, Net of Tax

The operating results of the Commercial and Industrial Lighting business have been reflected as discontinued operations. Income from discontinued operations, net of tax was $34.6 million in 2022 as compared to income of $34.5 million in 2021. Income from discontinued operations, net of taxes for the year ended December 31, 2022 and December 31, 2021 includes pre-tax transaction and separation costs of $8.8 million and $7.0 million, respectively. The provision for income taxes from discontinued operations in 2021 includes a one-time tax benefit of $25.1 million related to book-to-tax basis differences that was recognized in the period the business was classified as held-for-sale. The provision for income taxes from discontinued operations in 2022 reflects the tax effect of the book gain on sale.

Net sales in the Utility Solutions segment in 2022 were $2.9 billion, an increase of 23.0% as compared to 2021, due to a 22.9% increase in Organic Net sales driven by favorable price realization and higher unit volume, partially offset by the impact of a commercial resolution in the fourth quarter of 2022. Acquisitions, net of divestitures contributed 0.2% to Net sales growth in 2022 and foreign exchange was slightly unfavorable by 0.1%.

Operating income in the Utility Solutions segment in 2022 increased by 54.2% to $438.2 million as compared to 2021. Operating margin in 2022 increased to 15.3% as compared to 12.2% in 2021. Excluding amortization of acquisition-related intangibles the adjusted operating margin in 2022 increased by 230 basis points to 17.2% as compared to the prior year. The year-over-year increase in operating margin and adjusted operating margin was primarily driven by favorable price realization that was in excess of material cost inflation and higher unit volume, partially offset by higher freight, logistics and manufacturing costs, as well as other inflationary costs increases in excess of productivity, higher investments in our business and the impact of a commercial resolution in the fourth quarter of 2022.

Organic Net sales in 2022 increased by 10.6% as compared to the prior year primarily due to favorable price realization and higher unit volume. Net sales also increased by 1.7% from acquisitions and decreased by 0.6% from foreign exchange.

Operating income of the Electrical Solutions segment in 2022 was $270.9 million and increased approximately 9.1% compared to 2021, while operating margin in 2022 decreased by 30 basis points as compared to the prior year to 13.0%. Excluding amortization of acquisition-related intangibles, adjusted operating margin was 14.1% in 2022, which was flat compared to prior year. Operating margin in 2022 was impacted primarily due to favorable price realization that was in excess of material cost inflation and higher unit volume, partially offset by higher freight, logistics and manufacturing costs, as well as other inflationary costs increases in excess of productivity, and higher intangible amortization expense.

Financial Condition, Liquidity and Capital Resources

The current and prior period results presented below represent the results of our continuing operations, and exclude the results of the C&I Lighting business which are presented within cash provided by discontinued operations. See Note 2 - Discontinued Operations, in the Notes to the Consolidated Financial Statements for further details.

Cash Flow

			For the Year Ended December 31,
(in millions)			2022			2021
Net cash provided by (used in):
Operating activities from continuing operations			$	636.2		$	513.7
Investing activities from continuing operations			18.1			(72.1)
Financing activities (used in) from continuing operations			(437.1)			(433.0)

Effect of foreign currency exchange rate changes on cash and cash equivalents			(8.8)			(3.0)
NET CHANGE IN CASH AND CASH EQUIVALENTS			$	153.7		$	30.0

The following table reconciles our cash flows from operating activities to free cash flows for 2022 and 2021:

			For the Year Ended December 31,
(in millions)			2022			2021
Net cash provided by operating activities - Continuing Operations (GAAP measure)			$	636.2		$	513.7
Less: Capital expenditures - Continuing Operations			(129.3)			(90.2)
Free cash flow - Continuing Operations			$	506.9		$	423.5
Free cash flow as a percent of net income - continuing operations attributable to Hubbell			99.2		%	116.0		%

Free cash flow is a non-GAAP measure that we define as cash flow from operations less capital expenditures. Management believes that free cash flow provides useful information regarding Hubbell’s ability to generate cash without reliance on external financing. In addition, management uses free cash flow to evaluate the resources available for investments in the business, strategic acquisitions and further strengthening the balance sheet.

2022 Compared to 2021

 

Cash provided by operating activities from continuing operations was $636.2 million in 2022 compared to $513.7 million in 2021. The increase compared to the prior year is primarily due to higher net income, partially offset by changes in the components of working capital, as we invested in working capital to serve customer demand and growth in our order backlog.

Cash provided by investing activities was $18.1 million in 2022 compared to cash used of $72.1 million in 2021. That change was driven by $332.8 million in net proceeds from the disposal of the C&I Lighting business, partially offset by cash used of $177.1 million to acquire PCX Holdings LLC ("PCX"), Ripley Tools, LLC and Nooks Hill Road, LLC (collectively, "Ripley Tools") and REF Automation Limited and REF Alabama Inc. (collectively "REF") during 2022 and additional capital expenditures as we continue to invest in capacity expansion, automation and productivity initiatives.

Cash used in financing activities was $437.1 million in 2022 as compared to cash used of $433.0 million in 2021. The change in cash flows from financing activities primarily reflects an increase of $170.8 million of the Company's share repurchases in 2022 compared to 2021, partially offset by change in net borrowings.

The unfavorable impact of foreign currency exchange rates on cash was $8.8 million in 2022 as compared to a unfavorable effect of $3.0 million in 2021. The unfavorable impact in 2022 was primarily related to a weaker Canadian Dollar and British Pound compared to the U.S. Dollar.

Investments in the Business 

Investments in our business include cash outlays for the acquisition of businesses as well as expenditures to maintain the operation of our equipment and facilities and invest in restructuring activities.

In July 2022, the Company acquired all of the issued and outstanding membership interests of PCX for a cash purchase price of approximately $112.8 million, net of cash acquired. PCX is a leading designer and manufacturer of factory built modular power solutions for applications in the data center market. This business is reported in the Electrical Solutions segment. In July 2022, the Company also acquired all of the issued and outstanding membership interests of Ripley Tools for a cash purchase price of approximately $50.1 million, net of cash acquired. Ripley Tools is a leading manufacturer of cable and fiber prep tools and test equipment that serves both the utility and communications markets. This business is reported in the Utility Solutions segment.

In November 2022, the Company acquired all of the issued and outstanding equity interests of REF for a cash purchase price of $14.1 million. REF designs and manufactures electrical power components utilizing high-volume precision machining, as well as custom fabricated structural products and assemblies for the OEM, industrial and renewables markets. This business is reported in the Electrical Solutions segment.

We continue to invest in restructuring and related programs to maintain a competitive cost structure, to drive operational efficiencies and to mitigate the impact of rising material costs and administrative cost inflation. We expect our investment in restructuring and related activities to continue in 2023 as we continue to invest in previously initiated actions and initiate further footprint consolidation and other cost reduction initiatives.

In connection with our restructuring and related actions, we have incurred restructuring costs as defined by U.S. GAAP, which are primarily severance and employee benefits, asset impairments, accelerated depreciation, as well as facility closure, contract termination and certain pension costs that are directly related to restructuring actions. We also incurred restructuring-related costs, which are costs associated with our business transformation initiatives, including the consolidation of back-office functions and streamlining of our processes, and certain other costs and gains associated with restructuring actions. We refer to these costs on a combined basis as "restructuring and related costs", which is a non-GAAP measure. We believe this non-GAAP measure provides investors with useful information regarding our underlying performance from period to period. Restructuring costs are predominantly settled in cash from our operating activities and are generally settled within one year, with the exception of asset impairments, which are non-cash.

The table below presents the restructuring and related costs incurred in 2022, additional expected costs, and the expected completion date of restructuring actions that have been initiated as of December 31, 2022 and in prior years (in millions):

			Costs Incurred in 2022			Additional Expected Costs			Expected Completion Date
2022 Restructuring Actions			$	11.2		$	4.0		2023
2021 and Prior Restructuring Actions			(0.9)			2.6			2023
Restructuring cost (GAAP measure)			$	10.3		$	6.6
Restructuring-related costs			6.7			1.0
Restructuring and related costs (Non-GAAP measure)			$	17.0		$	7.6

During 2022, we invested $129.3 million in capital expenditures, an increase of $39.1 million as compared to 2021 as we increased capital investments to expand capacity, optimize footprint and implement automation and productivity initiatives.

 

Stock Repurchase Program

On October 23, 2020 the Board of Directors approved a stock repurchase program (the “October 2020 program”) that authorized the repurchase of up to $300 million of common stock and expires in October 2023. At December 31, 2022 our remaining share repurchase authorization under the October 2020 program is $106.7 million. On October 21, 2022 the Board of Directors approved a new stock repurchase program that authorized the repurchase of up to $300 million of common stock and expires in October 2025. The Company repurchased $182.0 million and $11.2 million of shares of common stock, in 2022 and 2021, respectively. When combined with the $106.7 million of remaining share repurchase authorization under the October 2020 program, we have a total share repurchase authorization remaining of approximately $406.7 million as of December 31, 2022. Subject to numerous factors, including market conditions and alternative uses of cash, we may conduct discretionary repurchases through open market or privately negotiated transactions, which may include repurchases under plans complying with Rules 10b5-1 and 10b-18 under the Securities Exchange Act of 1934, as amended.

Debt to Capital

At December 31, 2022 and 2021, the Company had $1,437.9 million and $1,435.5 million, respectively, of long-term debt outstanding, net of unamortized discount and the unamortized balance of capitalized debt issuance costs. At December 31, 2022 and December 31, 2021 the Company had no long-term debt with maturities due within the next twelve months.

Borrowings under Revolving Credit Facility

On March 12, 2021, the Company, as borrower, and its subsidiaries Hubbell Power Holdings S.à r.l. and Harvey Hubbell Holdings S.à r.l., each as a subsidiary borrower (collectively, the “Subsidiary Borrowers”) entered into a new five-year credit agreement with a syndicate of lenders and JPMorgan Chase Bank, N.A., as administrative agent, that provides a $750 million committed revolving credit facility (the “2021 Credit Facility"). Commitments under the 2021 Credit Facility may be increased to an aggregate amount not to exceed $1.25 billion. The 2021 Credit Facility includes a $50 million sub-limit for the issuance of letters of credit. The sum of the dollar amount of loans and letters of credits to the Subsidiary Borrowers under the 2021 Credit Facility may not exceed $75 million. There were no borrowings outstanding under the 2021 Credit Facility at December 31, 2022 or December 31, 2021.

The interest rate applicable to borrowings under the 2021 Credit Facility is (i) either the alternate base rate (as defined in the 2021 Credit Facility) or (ii) the adjusted LIBOR rate (as defined in the 2021 Credit Facility) plus an applicable margin based on the Company’s credit ratings. All revolving loans outstanding under the 2021 Credit Facility will be due and payable on March 12, 2026.

The 2021 Credit Facility contains a financial covenant requiring that, as of the last day of each fiscal quarter, the ratio of total indebtedness to total capitalization shall not be greater than 65%. The Company was in compliance with this covenant as of December 31, 2022.

Unsecured Senior Notes

On March 12, 2021, the Company completed a public offering of $300 million aggregate principal amount of its 2.300% Senior Notes due 2031 (the “2031 Notes” and collectively with those described below, the "Notes"). The net proceeds from the offering were approximately $295.5 million after deducting the underwriting discount and estimated offering expenses payable by the Company. The 2031 Notes bear interest at a rate of 2.300% per annum from March 12, 2021. Interest on the 2031 Notes is payable semi-annually in arrears on March 15 and September 15 of each year, beginning on September 15, 2021. The 2031 Notes will mature on March 15, 2031.

The Company used the net proceeds from the offering of the 2031 Notes, together with cash on hand, on April 2, 2021 to redeem in full all of the Company’s outstanding 3.625% Senior Notes due in 2022 for an aggregate principal amount of $300 million, which had a stated maturity date of November 15, 2022, and to pay the premium and accrued interest in respect thereof. The redemption of the 2022 Notes resulted in a $16.8 million loss on extinguishment that was recognized in the second quarter of 2021.

At December 31, 2021 and 2022 respectively, the Company had outstanding unsecured, senior notes in principal amounts of $400 million due in 2026, $300 million due in 2027, $450 million due in 2028 and $300 million due in 2031.

The carrying value of the Notes, net of unamortized discount and the unamortized balance of capitalized debt issuance costs, was $1,437.9 million and $1,435.5 million at December 31, 2022 and December 31, 2021, respectively.

The Notes are callable at any time at specified prices and are only subject to accelerated payment prior to maturity upon customary events of default, or upon a change in control triggering event as defined in the indenture governing the Notes, as supplemented. The Company was in compliance with all covenants (none of which are financial) as of December 31, 2022.

Short-term Debt

At December 31, 2022 and 2021, the Company had no commercial paper borrowings outstanding and had $4.7 million and $9.7 million, respectively, of short-term debt outstanding composed of:

◦$2.8 million at December 31, 2022 and $1.6 million at December 31, 2021, respectively, of borrowings to support our international operations in China as well as $1.9 million and $8.1 million of other short term debt at December 31, 2022 and December 31, 2021, respectively, to support other operations.

Liquidity 

We measure liquidity on the basis of our ability to meet short-term and long-term operational funding needs, to fund additional investments, including acquisitions, and to make dividend payments to shareholders. Significant factors affecting the management of liquidity are cash flows from operating activities, capital expenditures, cash dividend payments, stock repurchases, access to bank lines of credit and our ability to attract long-term capital with satisfactory terms.

In 2022, we returned capital to our shareholders through dividends and share repurchases. These activities were funded primarily with cash flows from operations.

◦In 2022, cash used for share repurchases was $182.0 million.

◦Dividends paid on our Common Stock in 2022 were $229.6 million.

We also require cash outlays to fund our operations, capital expenditures, and working capital requirements to accommodate anticipated levels of business activity, as well as our rate of cash dividends and potential future acquisitions. We have contractual obligations for long-term debt, operating leases, purchase obligations, and certain other long-term liabilities, including defined benefit retirement obligations and other benefits. Refer to Note 13 - Debt and Note 24 - Leases in the Notes to the Consolidated Financial Statements for further details on anticipated cash outflows. As a result of the Tax Cuts and Jobs Act ("TCJA"), we also have an obligation to fund, by annual installments through 2025, the Company's liability for the transition tax on the deemed repatriation of foreign earnings. Contractual purchase obligations for years subsequent to December 31, 2022 include approximately, $590 million in 2023. Contractual purchase obligations beyond 2023 are not significant.

Our purchase obligations include amounts committed under legally enforceable contracts or purchase orders for goods and services with defined terms as to price, quantity, delivery and termination liability. These obligations primarily consist of inventory purchases made in the normal course of business to meet operational requirements and commitments for equipment purchases. As of December 31, 2022, we have $42.1 million of uncertain tax positions reflected in our Consolidated Balance Sheet. We are unable to make a reasonable estimate regarding the timing of settlement of these uncertain tax positions and, as a result, they have been excluded from the disclosure. See Note 14 — Income Taxes in the Notes to Consolidated Financial Statements.

Our sources of funds and available resources to meet these funding needs are as follows:

◦Cash flows from operating activities and existing cash resources: In addition to our cash flows from operating activities, we also had $440.5 million of cash and cash equivalents at December 31, 2022, of which approximately 35% was held inside the United States and the remainder held internationally.

◦Our 2021 Credit Facility provides a $750.0 million committed revolving credit facility and commitments under the 2021 Credit Facility may be increased (subject to certain conditions) to an aggregate amount not to exceed $1.250 billion. Annual commitment fees to support availability under the 2021 Credit Facility are not material. Although not the principal source of liquidity, we believe our 2021 Credit Facility is capable of providing significant financing flexibility at reasonable rates of interest and is an attractive alternative source of funding in the event that commercial paper markets experience disruption. However, an increase in usage of the 2021 Credit Facility related to growth or a significant deterioration in the results of our operations or cash flows could cause our borrowing costs to increase and/or our ability to borrow could be restricted. We have not entered into any guarantees that could give rise to material unexpected cash requirements. The full $750.0 million of borrowing capacity under the 2021 Credit Facility was available to the Company at December 31, 2022.

◦In addition to our commercial paper program and existing revolving credit facility, we also have the ability to obtain additional financing through the issuance of long-term debt. Considering our current credit rating, historical earnings performance, and financial position, we believe that we would be able to obtain additional long-term debt financing on attractive terms.

 

◦The Company also maintains other lines of credit that are primarily used to support the issuance of letters of credit. Interest rates and other terms of borrowing under these lines of credit vary from country to country, depending on local market conditions. At December 31, 2022 and 2021, total availability under these lines was $55.8 million and $30.0 million, respectively, of which $31.7 million and $23.2 million was utilized to support letters of credit and the remaining amount was unused. The annual commitment fees associated with these lines of credit are not material.

Pension Funding Status

We have a number of funded and unfunded non-contributory U.S. and foreign defined benefit pension plans. Benefits under these plans are generally provided based on either years of service and final average pay or a specified dollar amount per year of service. The funded status of our qualified, defined benefit pension plans is dependent upon many factors including future returns on invested pension assets, the level of market interest rates, employee earnings and employee demographics.

In 2022, the Company recognized a settlement loss within continuing operations relating to retirees that elected to receive lump-sum distributions from the Company's defined benefit pension plans of $7.0 million. This charge was the result of lump-sum payments which exceeded the threshold for settlement accounting under U.S. GAAP in such year.

Changes in the value of the defined benefit plan assets and liabilities will affect the amount of pension expense ultimately recognized. Although differences between actuarial assumptions and actual results are no longer deferred for balance sheet purposes, deferral is still permitted for pension expense purposes. Unrecognized gains and losses in excess of an annual calculated minimum amount (the greater of 10% of the projected benefit obligation or 10% of the market value of assets) have been amortized and recognized in net periodic pension cost. Effective January 1, 2020, the amortization of unrecognized gains and losses of all of the Company's qualified defined benefit pension plans is recognized over the remaining life expectancy of participants, as all participants are considered inactive as a result of plan amendments. During 2022 and 2021, we recorded $10.8 million and $10.8 million, respectively, of pension expense related to the amortization of these unrecognized losses.

In 2022 and 2021, we contributed $12.5 million and $0.1 million, respectively, to our qualified foreign and domestic defined benefit pension plans. These contributions have improved the funded status of those plans. Although not required by ERISA and the Internal Revenue Code, the Company may elect to make a voluntary contribution to its qualified domestic defined benefit pension plan in 2023. The anticipated level of pension funding in 2023 is not expected to have a significant impact on our overall liquidity.

Assumptions 

The following assumptions were used to determine projected pension and other benefit obligations at the measurement date and the net periodic benefit costs for the year:

			Pension Benefits									Other Benefits
			2022			2021						2022			2021
Weighted-average assumptions used to determine benefit obligations at December 31,
Discount rate			5.46		%	2.79		%				5.50		%	2.90		%
Rate of compensation increase			0.08		%	0.08		%				3.93		%	3.87		%
Weighted-average assumptions used to determine net periodic benefit cost for years ended December 31,
Discount rate			2.79		%	2.47		%				2.90		%	2.50		%
Expected return on plan assets			4.59		%	4.66		%				N/A			N/A
Rate of compensation increase			0.08		%	0.24		%				3.87		%	3.99		%

 

At the end of each year, we estimate the expected long-term rate of return on pension plan assets based on the strategic asset allocation for our plans. In making this determination, we utilize expected rates of return for each asset class based upon current market conditions and expected risk premiums for each asset class. A one percentage point change in the expected long-term rate of return on pension fund assets would have an impact of approximately $5.2 million on 2023 pretax pension expense. The expected long-term rate of return is applied to the fair market value of pension fund assets to produce the expected return on fund assets that is included in pension expense.

The difference between this expected return and the actual return on plan assets was recognized at December 31, 2022 for balance sheet purposes, but continues to be deferred for expense purposes. The net deferral of past asset gains (losses) ultimately affects future pension expense through the amortization of gains (losses) with an offsetting adjustment to Hubbell shareholders’ equity through Accumulated other comprehensive loss.

 

At the end of each year, we determine the discount rate to be used to calculate the present value of our pension plan liabilities. For our U.S. and Canadian pension plans, this discount rate is determined by matching the expected cash flows associated with our benefit obligations to the expected cash flows of a hypothetical portfolio of high quality, fixed income debt instruments with maturities that closely match the expected funding period of our pension liabilities. As of December 31, 2022, we used a discount rate of 5.50% for our U.S. pension plans compared to a discount rate of 2.90% used in 2021. For our Canadian pension plan, we used a discount rate of 5.01% in 2022, compared to a 2.98% discount rate used in 2021.

 

For our UK pension plan the discount rate was derived using a full yield curve and uses plan specific cash flows. The derived discount rate is the single discount rate equivalent to discounting these liability cash flows at the term-dependent spot rates of AA corporate bonds. This methodology resulted in a December 31, 2022 discount rate for the UK pension plan of 5.00% as compared to a discount rate of 1.80% used in 2021. 

A decrease of one percentage point in the discount rate would increase our 2023 pretax pension expense by approximately $0.3 million. A discount rate increase of one percentage point would decrease our 2023 pretax pension expense by $0.5 million.

In 2021 and 2022 we used the Pri-2012 mortality table to calculate the present value of our pension plan liabilities and adopted the MP-2021 projection scale. The Pri-2012 mortality table with adjustment for collar as appropriate and generational projection from 2012 using Scale MP-2021 was chosen as the best estimate based on the observed and anticipated experience of the plans after considering alternative tables.

Other Post-Employment Benefits (“OPEB”) 

The Company also has a number of health care and life insurance benefit plans covering eligible employees who reached retirement age while working for the Company. These benefits have been discontinued for substantially all future retirees. These plans are not funded and, therefore, no assumed rate of return on assets is required. We use a similar methodology to derive the discount rate for our post employment benefit plan obligations that we use for our pension plans. As of December 31, 2022, the Company used a discount rate of 5.50% to determine the projected benefit obligation compared to a discount rate of 2.90% used in 2021.

In accordance with the accounting guidance for retirement benefits, we recorded to Accumulated other comprehensive loss, within Hubbell shareholders’ equity, a benefit, net of tax, of $5.5 million in 2022 and $3.4 million in 2021, respectively, related to the annual remeasurement of the OPEB plans and the amortization of prior service credits and net actuarial gains.

Off-Balance Sheet Arrangements

Off-balance sheet arrangements are defined as any transaction, agreement or other contractual arrangement to which an entity that is not included in our consolidated results is a party, under which we, whether or not a party to the arrangement, have, or in the future may have: (1) an obligation under a direct or indirect guarantee or similar arrangement, (2) a retained or contingent interest in assets transferred to an unconsolidated entity or similar arrangement that serves as credit, liquidity or market risk support to such entity for such assets, (3) an obligation or liability, including a contingent obligation or liability, under a contract that would be accounted for as a derivative instrument, except that it is excluded from the scope of FASB ASC Topic 815, or (4) an obligation, including a contingent obligation, arising out of a variable interest in an unconsolidated entity that is held by, and material to, the Company, where such entity provides financing, liquidity, market risk or credit risk support to, or engages in leasing, hedging or research and development services with, the Company.

We do not have any off-balance sheet arrangements as defined above which have or are likely to have a current or future material effect on our financial condition, results of operations, liquidity, capital expenditures, capital resources or cash flows.

Critical Accounting Estimates 

Note 1 — Significant Accounting Policies in the Notes to Consolidated Financial Statements describes the significant accounting policies used in the preparation of our financial statements.

 

Use of Estimates

We are required to make assumptions and estimates and apply judgments in the preparation of our financial statements that affect the reported amounts of assets and liabilities, revenues and expenses and related disclosures. We base our assumptions, estimates and judgments on historical experience, current trends and other factors deemed relevant by management, such as projections of future performance. We continually review these estimates and their underlying assumptions to ensure they are appropriate for the circumstances. Changes in estimates and assumptions used by us could have a material impact on our financial results, and actual results could differ significantly from those estimates. We believe that the following estimates are among the most critical in fully understanding and evaluating our reported financial results. These items utilize assumptions and estimates about the effect of future events that are inherently uncertain and are based on our judgment.

Revenue Recognition

 

The Company recognizes revenue when performance obligations identified under the terms of contracts with its customers are satisfied, which generally occurs, for products, upon the transfer of control in accordance with the contractual terms and conditions of the sale. The majority of the Company’s revenue associated with products is recognized at a point in time when the product is shipped to the customer, with a relatively small amount of transactions in the Utility Solutions segment recognized upon delivery of the product at the contractually specified destination. Revenue from service contracts and post-shipment performance obligations is approximately two percent of total annual consolidated net revenue and those service contracts and post-shipment obligations are primarily within the Utility Solutions segment. Revenue from service contracts and post-shipment performance obligations is recognized when or as those obligations are satisfied. The Company primarily offers assurance-type standard warranties that do not represent separate performance obligations and on occasion will separately offer and price extended warranties that are separate performance obligations for which the associated revenue is recognized over-time based on the extended warranty period. The Company records amounts billed to customers for reimbursement of shipping and handling costs within revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as fulfillment costs and are included in cost of goods sold. Sales taxes and other usage-based taxes are excluded from revenue.

The Company has certain arrangements that require us to estimate at the time of sale the amounts of variable consideration that should not be recorded as revenue as certain amounts are not expected to be collected from customers, as well as an estimate of the value of the product to be returned. The Company principally relies on historical experience, specific customer agreements and anticipated future trends to estimate these amounts at the time of shipment and to reduce the transaction price. These arrangements include sales discounts and allowances based on sales volumes, specific programs and special pricing allowances, and returned goods, as are customary in the electrical products industry. Customer returns have historically been approximately one percent of gross sales.

Inventory Valuation

 

Inventories in the U.S. are primarily valued at the lower of LIFO cost or market, while non-U.S. inventories are valued at the lower of FIFO cost or market. We routinely evaluate the carrying value of our inventories to ensure they are carried at the lower of LIFO or FIFO cost or market value. Such evaluation is based on our judgment and use of estimates, including sales forecasts, gross margins for particular product groupings, planned dispositions of product lines, technological events and overall industry trends. In addition, the evaluation is based on changes in inventory management practices which may influence the timing of exiting products and method of disposing of excess inventory.

 

Excess inventory is generally identified by comparing future expected inventory usage to actual on-hand quantities. Inventory values are reduced for on-hand inventory in excess of pre-defined usage forecasts. Forecast usage is primarily determined by projecting historical (actual) sales and inventory usage levels forward to future periods. Changes in these estimates may necessitate future adjustments to inventory values.

 

Employee Benefits Costs and Funding

 

We sponsor domestic and foreign defined benefit pension, defined contribution and other postretirement plans. Significant assumptions used in the accounting for these employee benefit plans include the discount rate, expected return on the pension fund assets, rate of increase in employee compensation levels and health care cost increase projections. These assumptions are determined based on Company data and appropriate market indicators, and are evaluated each year as of the plans’ measurement dates. Further discussion of the assumptions used in 2022 and 2021 are included above under “Pension Funding Status” and in Note 12 — Retirement Benefits in the Notes to Consolidated Financial Statements.

HUBBELL INCORPORATED - Form 10-K			35

---

Taxes

 

We account for income taxes in accordance with the applicable accounting guidance which requires that deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between the book and tax basis of recorded assets and liabilities. Additionally, deferred tax assets are required to be reduced by a valuation allowance if it is more-likely-than-not that some portion or all of a deferred tax asset will not be realized. The factors used to assess the likelihood of realization of deferred tax assets are the forecast of future taxable income, available tax planning strategies that could be implemented to realize the net deferred tax assets, and future reversals of deferred tax liabilities. Failure to achieve forecasted taxable income can affect the ultimate realization of net deferred tax assets.

We operate within multiple taxing jurisdictions and are subject to audit in these jurisdictions. The Internal Revenue Service (“IRS”) and other tax authorities routinely review our tax returns. These audits can involve complex issues, which may require an extended period of time to resolve. The Company records uncertain tax positions when it has determined that it is more-likely-than-not that a tax position will not be sustained upon examination by taxing authorities based on the technical merits of the position. The Company uses the criteria established in the accounting guidance to determine whether an item meets the definition of more-likely-than-not. The Company’s policy is to recognize these uncertain tax positions when the more-likely-than-not threshold is met, when the statute of limitations has expired or upon settlement. In management’s opinion, adequate provision has been made for potential adjustments arising from any examinations. See Note 14 — Income Taxes in the Notes to Consolidated Financial Statements.

Valuation of Long-Lived Assets, Goodwill, and Indefinite-Lived Intangible Assets

 

Our long-lived assets include land, buildings, equipment, molds and dies, software, goodwill and other intangible assets. Long-lived assets, other than land, goodwill and indefinite-lived intangibles, are depreciated over their estimated useful lives. The assets and liabilities of acquired businesses are recorded under the acquisition method of accounting at their estimated fair values at the dates of acquisition. Goodwill represents purchase price in excess of fair values assigned to the underlying identifiable net assets of acquired businesses. Intangible assets primarily consist of patents, tradenames, developed technology and customer related intangibles.

Goodwill and indefinite-lived intangible assets are reviewed annually for impairment unless circumstances dictate the need for more frequent assessment. We perform our annual goodwill impairment testing as of April 1st of each year. The accounting guidance provides entities an option of performing a qualitative assessment (the "Step-zero" test) before performing a quantitative analysis. If the entity determines, on the basis of certain qualitative factors, that it is more-likely-than-not that the goodwill is not impaired, the entity would not need to proceed to the quantitative goodwill impairment testing process as prescribed in the guidance. If the Company does not elect to complete the qualitative assessment, the Company completes the quantitative assessment whereby the estimated fair value of each reporting unit is compared to its carrying value.

The organizational changes within Electrical Solutions effective January 1, 2022 resulted in a change in the Company’s reporting units. As a result, the Company performed an interim goodwill impairment assessment as of January 1, 2022. For the three reporting units within the Electrical Solutions segment, the Company elected to utilize the quantitative goodwill impairment testing process, as permitted in the accounting guidance, by comparing the estimated fair value of the reporting units to their carrying values. The Company did not have any reporting units at risk of failing the quantitative impairment test as the excess of the implied fair value exceeded the carrying value of each of the reporting units. Additionally, the Company did not have any reporting units with zero or negative carrying amounts.

The Company also completed its annual goodwill impairment test as of April 1, 2022. The Company applied the Step-zero test to one of its four reporting units. Based on the qualitative assessment, the Company concluded that it was more likely than not that the fair value of this reporting unit substantially exceeded its carrying value and, therefore, further quantitative analysis was not required. For the other three reporting units, the Company elected to utilize the quantitative goodwill impairment testing process, as permitted in the accounting guidance, by comparing the estimated fair value of the reporting units to their carrying values. As of April 1, 2022, the impairment testing resulted in implied fair values of our reporting units that exceeded the reporting unit’s carrying value, including goodwill. The range of fair value in excess of carrying value, including goodwill, of the reporting units was 57% to 308%. The Company did not have any reporting units with zero or negative carrying amounts.

36			HUBBELL INCORPORATED - Form 10-K

---

The goodwill impairment test requires judgment, including the identification of reporting units, assigning assets and liabilities to reporting units, and determining the fair value of each reporting unit. Significant judgments required to estimate the fair value of reporting units include estimating future discounted cash flows, determining appropriate discount rates and other assumptions, including assumptions about secular economic and market conditions, such as increases in interest rates, the potential continuing effects of the COVID-19 pandemic, impacts to the supply chain and higher inflation. We use internal discounted cash flow models to estimate fair value. These cash flow estimates are derived from historical experience, third-party end market data, and future long-term business plans and include assumptions of future sales growth, gross margin, operating margin, terminal growth rate, and the application of an appropriate discount rate. Changes in these estimates and assumptions could materially affect the determination of fair value and/or goodwill impairment for each reporting unit. We corroborate the values determined from our discounted cash flow models by reconciling the sum of the estimated fair values of each reporting unit to our market capitalization at the testing date, including consideration of a control premium. We have not recorded any goodwill impairments since the initial adoption of the accounting guidance in 2002.

 

The identification and measurement of impairment of indefinite-lived intangible assets involves either an assessment of qualitative factors to determine whether events or circumstances indicate that it is more-likely-than-not that an indefinite-lived intangible asset is impaired or a quantitative assessment whereby the estimated fair value of each indefinite-lived intangible asset is compared to its carrying value. If it is more-likely-than-not that the asset is impaired, the fair value of the indefinite lived intangibles will be determined using discounted cash flow estimates. If the carrying value of these assets exceeds the estimated fair value, the carrying value will be reduced to the estimated fair value. For the Company’s annual impairment test as of April 1, 2022, the Company elected to utilize the quantitative impairment testing process as permitted in the accounting guidance. The fair value was determined utilizing an income approach (relief from royalty method). Significant judgment is required to estimate the fair value of the indefinite-lived intangible assets including assumptions for future revenues, discount rates, royalty rates, and other assumptions, including assumptions about secular economic and market conditions, such as the potential continuing effects of the COVID-19 pandemic. Significant changes in these estimates and assumptions could affect the determination of fair value and/or impairment for each indefinite-lived intangible asset. As of April 1, 2022, the impairment testing resulted in fair values for each indefinite-lived intangible asset that significantly exceeded the carrying values and there were no indefinite-lived intangible assets at risk of failing the quantitative impairment test. We did not record any impairments related to indefinite-lived intangible assets in 2022, 2021, or 2020.

Any such forward-looking statements are not guarantees of future performances and actual results, developments and business decisions may differ from those contemplated by such forward-looking statements. The Company disclaims any duty to update any forward-looking statement, all of which are expressly qualified by the foregoing, other than as required by law.

ITEM 7A    Quantitative and Qualitative Disclosures about Market Risk

In the operation of our business, we have various exposures to areas of risk related to factors within and outside the control of management. Significant areas of risk and our strategies to manage the exposure are discussed below.

 

In 2022, we manufactured and/or assembled products in the United States, Canada, Puerto Rico, Mexico, China, the UK, Brazil, Spain and Australia and sold products in those markets as well as through offices in Singapore, Italy, China, Mexico, and South Korea and countries in the Middle East. In 2022, Hubbell also participated in joint ventures in Hong Kong and the Philippines. As a percentage of the Company’s total Net sales, shipments from foreign operations directly to third parties were 8% in 2022, 9% in 2021 and 9% in 2020, with the Canadian and UK operations representing approximately 32% and 31%, respectively, of 2022 total international Net sales. As such, our operating results could be affected by changes in foreign currency exchange rates or weak economic conditions in the foreign markets in which we sell our products. To manage this exposure, we closely monitor the working capital requirements of our international units and may enter into forward foreign exchange contracts.

 

Product purchases representing approximately 15% of our Net sales are sourced from unaffiliated suppliers located outside the United States, primarily in Mexico, China and other Asian countries, Europe, India and Brazil. Foreign sourcing of products may result in unexpected fluctuations in product cost or increased risk of business interruption due to lack of product or component availability due to any one of the following:

 

•Political or economic uncertainty in the source country

•Fluctuations in the rate of exchange between the U.S. dollar and the currencies of the source countries

•Changes in U.S. laws and policies governing foreign trade

•Increased logistical complexity including supply chain interruption or delay, port of departure or entry disruption and overall time to market

•Loss of proprietary information

•Product quality issues outside the control of the Company

HUBBELL INCORPORATED - Form 10-K			39

---

We have developed plans that address many of these risks. Such actions include careful selection of products to be outsourced and the suppliers selected; ensuring multiple sources of supply; limiting concentrations of activity by port, broker, freight forwarder, etc.; processes related to quality control; and maintaining control over operations, technologies and manufacturing deemed to provide a competitive advantage. Many of our businesses have a dependency on certain basic raw materials needed to produce their products including steel, aluminum, brass, copper, bronze, zinc, nickel, plastics, phenols, elastomers and petrochemicals as well as purchased electrical and electronic components. Our financial results could be affected by the availability and changes in prices of these materials and components.

 

Certain of these materials are sourced from a limited number of suppliers. These materials are also key source materials for many other companies in our industry and within the universe of industrial manufacturers in general. As such, in periods of rising demand for these materials, we may experience both increased costs and/or limited supply. These conditions can potentially result in our inability to acquire these key materials on a timely basis to produce our products and satisfy our incoming sales orders. Similarly, the cost of these materials can rise suddenly and result in materially higher costs of producing our products. We believe we have adequate primary and secondary sources of supply for each of our key materials and that, in periods of rising prices, we expect to recover a majority of the increased cost in the form of higher selling prices. However, recoveries typically lag the effect of cost increases due to the nature of our markets.

 

Our financial results are subject to interest rate fluctuations to the extent there is a difference between the amount of our interest-earning assets and the amount of interest-bearing liabilities. The principal objectives of our investment management activities are to preserve capital while earning net investment income that is commensurate with acceptable levels of interest rate, default and liquidity risk taking into account our funding needs. As part of our investment management strategy, we may use derivative financial products such as interest rate hedges and interest rate swaps.

From time to time or when required, we issue commercial paper, which exposes us to changes in interest rates. Our cash position includes amounts denominated in foreign currencies. We manage our worldwide cash requirements by considering available funds held by our subsidiaries and the cost effectiveness with which these funds can be accessed.

As of December 31, 2022, the long-term debt outstanding related to the fixed-rate senior notes was $1,450.0 million. The senior notes are not exposed to interest rate risk as the bonds are at a fixed-rate until maturity.

 

We continually evaluate risk retention and insurance levels for product liability, property damage and other potential exposures to risk. We devote significant effort to maintaining and improving safety and internal control programs, which are intended to reduce our exposure to certain risks. We determine the level of insurance coverage and the likelihood of a loss and believe that the current levels of risk retention are consistent with those of comparable companies in the industries in which we operate. There can be no assurance that we will not incur losses beyond the limits of our insurance. However, our liquidity, financial position and profitability are not expected to be materially affected by the levels of risk retention that we accept. 

The following table presents cost and weighted average interest rate information related to financial instruments that are sensitive to changes in interest rates, by maturity at December 31, 2022 (dollars in millions):

Reports of Management

 

Report on Management’s Responsibility for Financial Statements

 

Our management is responsible for the preparation, integrity and fair presentation of our published financial statements. The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America and include amounts based on informed judgments made by management.

 

We believe it is critical to provide investors and other users of our financial statements with information that is relevant, objective, understandable and timely, so that they can make informed decisions. As a result, we have established and maintain systems and practices and internal control processes designed to provide reasonable, but not absolute, assurance that transactions are properly executed and recorded and that our policies and procedures are carried out appropriately. Management strives to recruit, train and retain high quality people to ensure that controls are designed, implemented and maintained in a high-quality, reliable manner.

 

Our independent registered public accounting firm audited our financial statements and the effectiveness of our internal control over financial reporting in accordance with standards established by the Public Company Accounting Oversight Board (United States). Their report appears on the next page within this Annual Report on Form 10-K.

 

Our Board of Directors normally meets at least eight times per year to provide oversight, to review corporate strategies and operations, and to assess management’s conduct of the business. The Board of Directors also schedules additional meetings on an as needed basis. The Audit Committee of our Board of Directors is composed of at least three individuals all of whom must be “independent” under current New York Stock Exchange listing standards and regulations adopted by the SEC under the federal securities laws. The Audit Committee meets regularly with our internal auditors and independent registered public accounting firm, as well as, management to review, among other matters, accounting, auditing, internal controls and financial reporting issues and practices. Both the internal auditors and independent registered public accounting firm have full, unlimited access to the Audit Committee.

Management’s Annual Report on Internal Control over Financial Reporting

 

Management is responsible for establishing and maintaining adequate systems of internal control over financial reporting as defined by Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with generally accepted accounting principles in the United States of America. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Management has assessed the effectiveness of our internal control over financial reporting as of December 31, 2022.

During the year ended December 31, 2022, the Company acquired PCX Holdings LLC, Ripley Tools, LLC and Nooks Hill Road, LLC, and REF Automation Limited and REF Alabama Inc. for an aggregate purchase price of $177.1 million. Because the Company has not yet fully incorporated the internal controls and procedures of the acquired entities into the Company's internal control over financial reporting, management excluded these businesses from its assessment of the effectiveness of internal control over financial reporting as of December 31, 2022. These entities accounted for 2% of the Company's total assets excluding intangibles and goodwill as of December 31, 2022 and less than 1% of the Company's net sales for the year then ended December 31, 2022.

In making this assessment, management used the criteria set forth in Internal Control-Integrated Framework (2013 framework) issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). Based on this assessment, management concluded that our internal control over financial reporting was effective at a reasonable assurance level as of December 31, 2022.

 

The effectiveness of our internal control over financial reporting as of December 31, 2022 has been audited by PricewaterhouseCoopers LLP, our independent registered public accounting firm as stated in their report which is included below within this Annual Report on Form 10-K.

Report of Independent Registered Public Accounting Firm

  

To the Board of Directors and Shareholders of Hubbell Incorporated

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Hubbell Incorporated and its subsidiaries (the “Company”) as of December 31, 2022 and 2021, and the related consolidated statements of income, of comprehensive income, of changes in equity and of cash flows for each of the three years in the period ended December 31, 2022, including the related notes and schedule of valuation and qualifying accounts for each of the three years in the period ended December 31, 2022 appearing under Item 15 (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Annual Report on Internal Control over Financial Reporting appearing under Item 8. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

As described in Management’s Annual Report on Internal Control over Financial Reporting, management has excluded PCX Holdings LLC, Ripley Tools, LLC and Nooks Hill Road, LLC, and REF Automation Limited and REF Alabama Inc. from its assessment of internal control over financial reporting as of December 31, 2022 because they were acquired by the Company in a purchase business combination during 2022. We have also excluded PCX Holdings LLC, Ripley Tools, LLC and Nooks Hill Road, LLC, and REF Automation Limited and REF Alabama Inc. from our audit of internal control over financial reporting. PCX Holdings LLC, Ripley Tools, LLC and Nooks Hill Road, LLC, and REF Automation Limited and REF Alabama Inc. are wholly-owned subsidiaries whose total assets and total revenues excluded from management’s assessment and our audit of internal control over financial reporting represent 2% and 1%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2022.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

HUBBELL INCORPORATED - Form 10-K			43

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Goodwill Impairment Assessments – One of the Reporting Units Subject to a Quantitative Assessment

As described in Notes 1 and 7 to the consolidated financial statements, the Company’s consolidated goodwill balance was $1,970.5 million as of December 31, 2022. Goodwill represents purchase price in excess of fair values of the underlying net assets of acquired companies. Goodwill is subject to annual impairment testing. Management performs its goodwill impairment testing as of April 1st of each year, unless circumstances dictate the need for more frequent assessments. On January 1, 2022, the Company reorganized certain businesses within the Electrical Solutions segment to simplify the organization structure and align the organization to better serve their customers. As a result of the change in reporting units, management performed an interim goodwill impairment assessment prior to the change, for reporting units within the Electrical Solutions segment. As disclosed by management, management also completed its annual goodwill impairment assessment as of April 1, 2022. For three of its reporting units, management elected to utilize the quantitative goodwill impairment testing process, as permitted in the accounting guidance, by comparing the estimated fair value of the Company's reporting units to their carrying values for both assessments. If the estimated fair value of the reporting unit exceeds its carrying value, no impairment exists. Goodwill impairment testing requires judgment by management, including the identification of reporting units, assigning assets and liabilities to reporting units and determining the fair value of each reporting unit. Management uses internal discounted cash flow models to estimate fair value. Significant judgments required by management to estimate the fair value of reporting units include estimating future cash flows, determining appropriate discount rates and other assumptions, including assumptions about secular economic and market conditions, such as the potential continuing effects of the COVID-19 pandemic, impacts to the supply chain and higher inflation. These cash flow estimates are derived from historical experience, third party end market data, and future long-term business plans and include assumptions of future sales growth, gross margin, operating margin, terminal growth rate and the application of an appropriate discount rate.

The principal considerations for our determination that performing procedures relating to the goodwill impairment assessment for one of the reporting units subject to a quantitative assessment is a critical audit matter are (i) the significant judgment by management when estimating the fair value of the reporting unit and (ii) the high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management’s significant assumptions related to future sales growth, gross margin, and operating expenses.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s quantitative goodwill impairment assessment, including controls over the estimation of the fair value of the reporting unit. These procedures also included, among others, (i) testing management’s process for estimating the fair value of the reporting unit; (ii) evaluating the appropriateness of the discounted cash flow model; (iii) testing the completeness and accuracy of the underlying data used in the model; and (iv) evaluating the reasonableness of significant assumptions used by management related to future sales growth, gross margin, and operating expenses. Evaluating management’s assumptions related to the future sales growth, gross margin, and operating expenses involved evaluating whether the assumptions used by management were reasonable considering (i) the current and past performance of the reporting unit; (ii) the consistency with industry and third party data; and (iii) whether these assumptions were consistent with evidence obtained in other areas of the audit.

(1) For accounting purposes, the Company treats repurchased shares as constructively retired when acquired and accordingly charges the purchase price against Common Stock par value, Additional paid-in capital, to the extent available, and Retained earnings. The change in Retained earnings of $170.5 million, $15.8 million and $34.1 million in 2022, 2021 and 2020, respectively, reflects this accounting treatment.

Notes to Consolidated Financial Statements

NOTE 1    Significant Accounting Policies

 

Basis of Presentation

 

The accompanying consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”).

On February 1, 2022, the Company completed the sale of the Commercial and Industrial Lighting business (the "C&I Lighting business") to GE Current, a Daintree Company, for total net cash consideration of $332.8 million. The C&I Lighting business had sales of $509.4 million in 2021 as part of the Electrical Solutions segment and designs, manufactures, and sells LED lighting and control solutions for commercial and industrial customers. As a result of the agreement, the C&I Lighting business met the criteria set forth in ASC 205-20 to be presented as a discontinued operation. The C&I Lighting business' results of operations and the related cash flows have been presented as income from discontinued operations in the Consolidated Statements of Income and cash flows from discontinued operations in the Consolidated Statements of Cash Flows, respectively, for all periods presented. See Note 2, Discontinued Operations, to the Consolidated Financial Statements for further information.

Principles of Consolidation

 

The Consolidated Financial Statements include all wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated. The Company participates in two joint ventures that have been consolidated in accordance with the consolidation accounting guidance. An analysis is performed to determine which reporting entity, if any, has a controlling financial interest in a variable interest entity (“VIE”) with a primarily qualitative analysis. The qualitative analysis is based on identifying the party that has both the power to direct the activities that most significantly impact the VIE’s economic performance (the “power criterion”) and the obligation to absorb losses from or the right to receive benefits of the VIE that could potentially be significant to the VIE (the “losses/benefit criterion”). The party that meets both these criteria is deemed to have a controlling financial interest. The party with the controlling financial interest is considered to be the primary beneficiary and as a result is required to consolidate the VIE. The Company has a 50% interest in a joint venture in Hong Kong, established as Hubbell Asia Limited (“HAL”). The principal objective of HAL is to manage the operations of its wholly-owned manufacturing company in China. Under the accounting guidance, the Company is the primary beneficiary of HAL and as a result consolidates HAL.

This determination is based on the fact that HAL’s sole business purpose is to manufacture product exclusively for the Company (the power criterion) and the Company is financially responsible for ensuring HAL maintains a fixed operating margin (the losses/benefit criterion). The consolidation of HAL is not material to the Company’s consolidated financial statements.

Use of Estimates

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts in the Consolidated Financial Statements and accompanying Notes to Consolidated Financial Statements. Actual results could differ from the estimates that are used.

Impact of the COVID-19 Pandemic

During March 2020, a global pandemic was declared by the World Health Organization related to the rapidly growing outbreak of a novel strain of coronavirus (COVID-19). The pandemic has had, and may continue to have, a significant effect on global economic conditions. U.S. Federal, state, local, and foreign governments have reacted to the public health crisis with mitigation measures, creating significant uncertainties in the U.S. and global economies. The extent to which the coronavirus pandemic will continue to affect our business, operations, supply chains, and our financial results will depend on numerous evolving factors that we may not be able to accurately predict and which may cause the actual results to differ from the estimates and assumptions we are required to make in the preparation of financial statements according to GAAP.

Assets and Liabilities Held for Sale

The Company classifies assets and liabilities (disposal groups) to be sold as held for sale in the period in which all of the following criteria are met: management, having the authority to approve the action, commits to a plan to sell the disposal group; the disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such disposal groups; an active program to locate a buyer and other actions required to complete the plan to sell the disposal group have been initiated; the sale of the disposal group is probable, and transfer of the disposal group is expected to qualify for recognition as a completed sale within one year, except if events or circumstances beyond the Company's control extend the period of time required to sell the disposal group beyond one year; the disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.

---

The Company initially measures a disposal group that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a disposal group until the date of sale. The Company assesses the fair value of a disposal group, less any costs to sell, each reporting period it remains classified as held for sale and reports any subsequent changes as an adjustment to the carrying value of the disposal group, as long as the new carrying value does not exceed the carrying value of the disposal group at the time it was initially classified as held for sale.

Upon determining that a disposal group meets the criteria to be classified as held for sale, the Company reports the assets and liabilities of the disposal group, if material, in the line items assets held for sale and liabilities held for sale in the consolidated statements of financial position. Refer to Note 2, "Discontinued Operations," of the notes to Consolidated Financial Statements for further information. In conjunction with the C&I Lighting Business being classified as held for sale, depreciation and amortization ceased.

 

Revenue Recognition

 

The Company recognizes revenue when performance obligations identified under the terms of contracts with its customers are satisfied, which generally occurs, for products, upon the transfer of control in accordance with the contractual terms and conditions of the sale. The majority of the Company’s revenue associated with products is recognized at a point in time when the product is shipped to the customer, with a relatively small amount of transactions in the Utility Solutions segment recognized upon delivery of the product at the contractually specified destination. Revenue from service contracts and post-shipment performance obligations is approximately two percent of total annual consolidated net revenue and those service contracts and post-shipment obligations are primarily within the Utility Solutions segment. Revenue from service contracts and post-shipment performance obligations is recognized when or as those obligations are satisfied. The Company primarily offers assurance-type standard warranties that do not represent separate performance obligations and on occasion will separately offer and price extended warranties that are separate performance obligations for which the associated revenue is recognized over-time based on the extended warranty period. The Company records amounts billed to customers for reimbursement of shipping and handling costs within revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as fulfillment costs and are included in cost of goods sold. Sales taxes and other usage-based taxes are excluded from revenue.

Within the Electrical Solutions segment, certain businesses require a portion of the transaction price to be paid in advance of transfer of control. Advance payments are not considered a significant financing component as they are received less than one year before the related performance obligations are satisfied. In addition, in the Utility Solutions segment, certain businesses offer annual maintenance service contracts that require payment at the beginning of the contract period. These payments are treated as a contract liability and are classified in Other accrued liabilities in the Consolidated Balance Sheet. Once control transfers to the customer and the Company meets the revenue recognition criteria, the deferred revenue is recognized in the Consolidated Statement of Income. The deferred revenue relating to the annual maintenance service contracts is recognized in the Consolidated Statement of Income on a straight line basis over the expected term of the contract.

The Company has certain arrangements that require us to estimate at the time of sale the amounts of variable consideration that should not be recorded as revenue as certain amounts are not expected to be collected from customers, as well as an estimate of the value of the product to be returned. The Company principally relies on historical experience, specific customer agreements and anticipated future trends to estimate these amounts at the time of shipment and to reduce the transaction price. These arrangements include sales discounts and allowances based on sales volumes, specific programs and special pricing allowances, and returned goods, as are customary in the electrical products industry. Customer returns have historically been approximately 1% of gross sales.

Shipping and Handling Costs

 

The Company records shipping and handling costs as part of Cost of goods sold in the Consolidated Statement of Income.

 

Foreign Currency Translation

 

The assets and liabilities of international subsidiaries are translated to U.S. dollars at exchange rates in effect at the end of the year, and income and expense items are translated at average exchange rates in effect during the year. The effects of exchange rate fluctuations on the translated amounts of foreign currency assets and liabilities are included as translation adjustments in Accumulated other comprehensive loss within Hubbell shareholders’ equity. Gains and losses from foreign currency transactions are included in results of operations.

 

Cash and Cash Equivalents

 

The carrying value of cash equivalents approximates fair value. Cash equivalents consist of highly liquid investments with original maturities to the Company of three months or less.

 

HUBBELL INCORPORATED - Form 10-K			51

---

Investments

 

Investments in debt and equity securities are classified by individual security as available-for-sale, held-to-maturity or trading securities. Our available-for-sale securities, consisting of municipal bonds, are carried on the balance sheet at fair value with current period adjustments to carrying value recorded in Accumulated other comprehensive loss within Hubbell shareholders’ equity, net of tax. Realized gains and losses are recorded in income in the period of sale. The Company’s trading securities are carried on the balance sheet at fair value and consist primarily of debt and equity mutual funds. Gains and losses associated with these trading securities are reflected in the results of operations. The Company did not have any investments classified as held-to-maturity as of December 31, 2022 and 2021.

 

Accounts Receivable and Allowances

 

Trade accounts receivable are recorded at the invoiced amount and generally do not bear interest. The allowance for doubtful accounts is based on an estimated amount of probable credit losses in existing accounts receivable. The allowance is calculated based upon a combination of historical write-off experience, fixed percentages applied to aging categories and specific identification based upon a review of past due balances and problem accounts. Account balances are charged off against the allowance when it is determined that internal collection efforts should no longer be pursued. The Company also maintains a reserve for credit memos and cash discounts which are principally calculated based upon historical experience, specific customer agreements, as well as anticipated future trends.

 

Inventories

 

Inventories are stated at the lower of cost or market value. Approximately 60% of total net inventory value is determined utilizing the last-in, first-out (LIFO) method of inventory accounting. The cost of foreign inventories and certain domestic inventories is determined utilizing average cost or first-in, first-out (FIFO) methods of inventory accounting. Reserves for excess and obsolete inventory are provided based on current assessments about future demand compared to on-hand quantities.

Property, Plant, and Equipment

 

Property, plant, and equipment values are stated at cost less accumulated depreciation. Maintenance and repair expenditures that do not significantly increase the life of an asset are charged to expense when incurred. Property, plant, and equipment placed in service prior to January 1, 1999 are depreciated over their estimated useful lives, principally, using accelerated methods. Assets placed in service subsequent to January 1, 1999 are depreciated over their estimated useful lives, using straight-line methods. Leasehold improvements are amortized over the shorter of their economic lives or the lease term. Gains and losses arising on the disposal of property, plant and equipment are included in Operating income in the Consolidated Statement of Income.

 

Capitalized Computer Software Costs

 

Capitalized computer software costs, net of amortization, were $7.0 million and $10.8 million at December 31, 2022 and 2021, respectively. This balance is reflected in Other long-term assets in the Consolidated Balance Sheet. Capitalized computer software is for internal use and costs primarily consist of purchased materials, external services and salary costs for personnel dedicated to the projects. Software is amortized on a straight-line basis over appropriate periods, generally between three and five years. The Company recorded amortization expense of $6.6 million in 2022, $9.6 million in 2021 and $10.0 million in 2020 relating to capitalized computer software.

 

Goodwill and Other Intangible Assets

 

Goodwill represents purchase price in excess of fair values of the underlying net assets of acquired companies. Indefinite-lived intangible assets and goodwill are subject to annual impairment testing using the specific guidance and criteria described in the accounting guidance. The Company performs its goodwill impairment testing as of April 1st of each year, unless circumstances dictate the need for more frequent assessments. The accounting guidance provides entities an option of performing a qualitative assessment (a "step-zero" test) before performing a quantitative analysis. If the entity determines, on the basis of certain qualitative factors, that it is more-likely-than-not that the goodwill is not impaired, the entity would not need to proceed to quantitative goodwill impairment testing process as prescribed in the guidance. The Company applied the "step-zero" test to one of its four reporting units. Based on that qualitative assessment, the Company concluded it was more-likely-than-not that the fair value of this reporting unit exceeded its carrying value and therefore, further quantitative analysis was not required. For the other three reporting units the Company has elected to utilize the quantitative goodwill impairment testing process as permitted in the accounting guidance, by comparing the estimated fair value of the Company's reporting units to their carrying values. If the fair value of the reporting unit exceeds its carrying value, no impairment exists.

 

Goodwill impairment testing requires judgment, including the identification of reporting units, assigning assets and liabilities to reporting units and determining the fair value of each reporting unit. Significant judgments required to estimate the fair value of reporting units include estimating future discounted cash flows, determining appropriate discount rates and other assumptions, including assumptions about secular economic and market conditions, such as the potential continuing effects of the COVID-19 pandemic, impacts to the supply chain and higher inflation. We use internal discounted cash flow models to estimate fair value. These cash flow estimates are derived from historical experience, third party end market data, and future long-term business plans and include assumptions on future sales growth, gross margin, operating margin, terminal growth rate, and the application of an appropriate discount rate. Changes in these estimates and assumptions could affect the determination of fair value and/or goodwill impairment for each reporting unit. The Company believes that its estimated aggregate fair value of its reporting units is reasonable when compared to the Company's market capitalization on the valuation date.

---

On January 1, 2022, we internally reorganized certain businesses within our Electrical Solutions segment to simplify the organization structure and align the organization to better serve our customers. This change had no impact to our reportable segments. As a result of the change in reporting units, the Company performed an interim goodwill impairment assessment prior to the change, for the reporting units within the Electrical Solutions segment. Because the changes did not affect the Utility Solutions segment, no interim goodwill impairment assessment was required for that segment.

As of April 1, 2022, the impairment testing resulted in implied fair values of our reporting units that exceeded the reporting unit's carrying value, including goodwill. The range of fair value in excess of carrying value, including goodwill, of the reporting units was 57% to 308%. Additionally, the Company did not have any reporting units with zero or negative carrying amounts. The Company has not recorded any goodwill impairments since the initial adoption of the accounting guidance in 2002.

The Company’s intangible assets consist primarily of customer relationships, tradenames, developed technology and patents. Intangible assets with definite lives are amortized over periods generally ranging from 5-30 years. The Company amortizes intangible assets with definite lives using either an accelerated method that reflects the pattern in which economic benefits of the intangible assets are consumed and results in higher amortization in the earlier years of the assets' useful life, or using a straight line method. Approximately 80% of the gross value of definite-lived intangible assets follow an accelerated amortization method. These definite lived intangibles are tested for impairment whenever events or circumstances indicate that the carrying amount of an asset (asset group) may not be recoverable. An impairment loss is recognized when the carrying amount of an asset exceeds the estimated undiscounted cash flows used in determining the fair value of the asset. The Company did not record any material impairments related to its definite lived intangible assets in 2022, 2021 or 2020. The Company also has some tradenames that are considered to be indefinite-lived intangible assets. These indefinite-lived intangible assets are not amortized and are tested for impairment annually, unless circumstances dictate the need for more frequent assessment.

 

The identification and measurement of impairment of indefinite-lived intangible assets involves either an assessment of qualitative factors to determine whether events or circumstances indicate that it is more-likely-than-not that an indefinite-lived intangible asset is impaired or a quantitative assessment whereby the estimated fair value of each indefinite-lived intangible asset is compared to its carrying value. If it is more-likely-than-not that the asset is impaired, the fair value of the indefinite lived intangibles will be determined using discounted cash flow estimates. If the carrying value of these assets exceeds the estimated fair value, the carrying value will be reduced to the estimated fair value. For the Company’s annual impairment test as of April 1, 2022, the Company elected to utilize the quantitative impairment testing process as permitted in the accounting guidance. The fair value was determined utilizing an income approach (relief from royalty method). Significant judgment is required to estimate the fair value of the indefinite-lived intangible assets including assumptions for future revenues,

discount rates, royalty rates, and other assumptions, including assumptions about secular economic and market conditions, such as the potential continuing effects of the COVID-19 pandemic. Significant changes in these estimates and assumptions could affect the determination of fair value and/or impairment for each indefinite-lived intangible asset. As of April 1, 2022, the impairment testing resulted in fair values for each indefinite-lived intangible asset that significantly exceeded the carrying values and there were no indefinite-lived intangible assets at risk of failing the quantitative impairment test. The Company did not record any impairments related to indefinite-lived intangible assets in 2022, 2021 and 2020.

 

Other Long-Lived Assets

 

The Company reviews depreciable long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. If such a change in circumstances occurs, the related estimated future undiscounted cash flows expected to result from the use of the asset group and its eventual disposition is compared to the carrying amount. If the sum of the expected cash flows is less than the carrying amount, an impairment charge is recorded. The impairment charge is measured as the amount by which the carrying amount exceeds the fair value of the asset. The fair value of impaired assets is determined using expected cash flow estimates, quoted market prices when available and appraisals as appropriate. The Company did not record any material impairment charges in 2022, 2021 or 2020.

 

Leases

 

We determine if an arrangement is a lease at inception. Operating leases are included as ROU assets within other long-term assets, other accrued liabilities, and other non-current liabilities in our Consolidated Balance Sheets. Finance leases are included in property, plant, and equipment, net, other accrued liabilities, and other non-current liabilities. The Company's finance leases are immaterial.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. We use an implicit rate when readily determinable. For leases existing as of January 1, 2019, we have elected to use the remaining lease term as of the adoption date in determining the incremental borrowing rate. Our determination of the lease term may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option.

We have lease agreements with lease and non-lease components, which are generally accounted for separately. Additionally, for our vehicle leases, we apply a portfolio approach regarding the assumed lease term.

Accrued Insurance 

The Company retains a significant portion of the risks associated with workers’ compensation, medical, automobile and general liability insurance. The Company estimates self-insurance liabilities using a number of factors, including historical claims experience, demographic factors, and other actuarial assumptions. The accrued liabilities associated with these programs are based on the Company’s estimate of the ultimate costs to settle known claims as well as claims incurred but not reported as of the balance sheet date. The Company periodically reviews the assumptions with a third party actuary to determine the adequacy of these self-insurance reserves.

Accrued Warranty

The Company offers product warranties which cover defects on most of its products. These warranties primarily apply to products that are properly installed, maintained and used for their intended purpose. The Company accrues estimated warranty costs at the time of sale. Estimated warranty expenses, recorded in cost of goods sold, are based upon historical information such as past experience, product failure rates, or the estimated number of units to be repaired or replaced. Adjustments are made to the product warranty accrual as claims are incurred, additional information becomes known or as historical experience indicates.

Income Taxes

 

The Company operates within multiple taxing jurisdictions and is subject to audit in these jurisdictions. The IRS and other tax authorities routinely examine the Company’s tax returns. These audits can involve complex issues which may require an extended period of time to resolve. The Company makes adequate provisions for best estimates of exposures on previously filed tax returns. Deferred income taxes are recognized for the tax consequence of differences between financial statement carrying amounts and the tax basis of assets and liabilities by applying the currently enacted statutory tax rates in accordance with the accounting guidance for income taxes. The effect of a change in statutory tax rates is recognized in the period that includes the enactment date. Additionally, deferred tax assets are required to be reduced by a valuation allowance if it is more-likely-than-not that a portion or all of the deferred tax asset will not be realized. The Company uses factors to assess the likelihood of realization of deferred tax assets such as the forecast of future taxable income and available tax planning that could be implemented to realize the deferred tax assets.

 

In addition, the accounting guidance prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of the tax position taken or expected to be taken in a tax return. For any amount of benefit to be recognized, it must be determined that it is more-likely-than-not that a tax position will be sustained upon examination by taxing authorities based on the technical merits of the position. The amount of benefit to be recognized is based on the Company’s assertion of the most likely outcome resulting from an examination, including resolution of any related appeals or litigation processes. Companies are required to reflect only those tax positions that are more-likely-than-not to be sustained. See Note 14 — Income Taxes for additional information.

 

Research and Development

 

Research and development expenditures represent costs to discover and/or apply new knowledge in developing a new product, process, or in bringing about a significant improvement to an existing product or process. Research and development expenses are recorded as a component of Cost of goods sold. Expenses for research and development were approximately 2% of Net Sales in each of 2022 and 2021 and 3% in 2020.

 

Government Assistance

 

We have adopted Accounting Standards Update ("ASU") 2021-10, Government Assistance (Topic 832) Disclosures by Business Entities about Government Assistance, which requires footnote disclosure of assistance received from government entities. We record amounts received from government entities as a reduction of the associated expense. Amounts received related to depreciable assets are recognized as a reduction to depreciation expense. The total impact of government assistance was not material to the Company in 2022, and prior periods presented.

Retirement Benefits

The Company maintains various defined benefit pension plans for some of its U.S. and foreign employees. The accounting guidance for retirement benefits requires the Company to recognize the funded status of its defined benefit pension and postretirement plans as an asset or liability in the Consolidated Balance Sheet. Gains or losses, prior service costs or credits, and transition assets or obligations that have not yet been included in net periodic benefit cost as of the end of the year are recognized as components of Accumulated other comprehensive loss, net of tax, within Hubbell shareholders’ equity. The Company’s policy is to fund pension costs within the ranges prescribed by applicable regulations. In addition to providing defined benefit pension benefits, the Company provides health care and life insurance benefits for some of its active and retired employees. The Company’s policy is to fund these benefits through insurance premiums or as actual expenditures are made. See also Note 12 — Retirement Benefits.

Earnings Per Share

 

Restricted stock granted by the Company is considered a participating security since it contains a non-forfeitable right to dividends. As a result, the earnings per share accounting guidance requires the Company to use the two-class method for calculating earnings per share. The two-class method is an earnings allocation formula that determines earnings per share for common stock and participating securities. Basic earnings per share is calculated as net income available to common shareholders divided by the weighted average number of shares of common stock outstanding. Earnings per diluted share is calculated as net income available to common shareholders divided by the weighted average number of shares outstanding of common stock plus the incremental shares outstanding assuming the exercise of dilutive stock options, stock appreciation rights and performance shares. See also Note 19 — Earnings Per Share.

 

Stock-Based Compensation

 

The Company recognizes the grant-date fair value of all stock-based awards on a straight-line basis over their respective requisite service periods (generally equal to an award’s vesting period). A stock-based award is considered vested for expense attribution purposes when the retention of the award is no longer contingent on providing subsequent service. Accordingly, the Company generally recognizes compensation cost immediately for awards granted to retirement-eligible individuals or over the period from the grant date to the date retirement eligibility is achieved, if less than the stated vesting period. The expense is recorded in Cost of goods sold and S&A expense in the Consolidated Statement of Income based on the recipients’ respective functions within the organization.

 

The Company records deferred tax assets for awards that will result in deductions on its tax returns, based upon the amount of compensation cost recognized and the statutory tax rate in the jurisdiction in which it will receive a deduction. See also Note 18 — Stock-Based Compensation.

Recently Issued Accounting Pronouncements

In March 2020, the FASB issued ASU No. 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting", which provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments are effective for all entities beginning on March 12, 2020 through December 31, 2022. The Company may elect to apply the amendments prospectively through December 31, 2022.

In December 2022, the FASB issued ASU No. 2022-06 Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which extends the temporary accounting rules under Topic 848 to December 31, 2024. The Company is currently assessing the impact of adopting this standard on its financial statements and the timing of adoption.

NOTE 2 Discontinued Operations

 

On February 1, 2022, the Company completed the sale of the C&I Lighting business to GE Current, a Daintree Company, for total net cash consideration of $332.8 million. We have concluded the divestiture of this business represents a strategic shift that will have a major effect on our operations and financial results, and as a result, is reported as a discontinued operation in our Consolidated Financial Statements for all periods presented. The assets and liabilities of this business are also presented as held for sale in the Consolidated Balance Sheets for the year ended December 31, 2021. The C&I Lighting business was previously included in the Electrical Solutions segment.

Under the terms of the transaction, Hubbell and the buyer entered into a transition services agreement ("TSA"), pursuant to which the Company provides certain administrative and operational services for a period of 12 months or less. Furthermore, we entered into a short-term supply agreement whereby the Company acts as a supplier of finished goods and component parts to the C&I Lighting business after the completion of the sale. Income from the TSA and supply agreement was $13.3 million for the year ended December 31, 2022 and was recorded in Other Income in the Consolidated Financial Statements.

NOTE 3 Revenue

 

The Company recognizes revenue when performance obligations identified under the terms of contracts with its customers are satisfied, which generally occurs, for products, upon the transfer of control in accordance with the contractual terms and conditions of the sale. Approximately three-fourths of the Company's Net sales are to distributors who then sell directly into our end markets. Within the Utility Solutions segment, our businesses sell to distributors, with the majority of sales to the utility end markets and also directly into transmission and distribution utility markets. The majority of the Company’s revenue associated with products is recognized at a point in time when the product is shipped to the customer, with a relatively small amount of transactions, primarily in the Utility Solutions segment, recognized upon delivery of the product at the destination. Revenue from service contracts and post-shipment performance obligations is recognized when or as those obligations are satisfied. The Company primarily offers assurance-type standard warranties that do not represent separate performance obligations and on occasion will separately offer and price extended warranties that are separate performance obligations for which the associated revenue is recognized over-time based on the extended warranty period. The Company records amounts billed to customers for reimbursement of shipping and handling costs within revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as fulfillment costs and are included in cost of goods sold. Sales taxes and other usage-based taxes are excluded from revenue.

Within the Electrical Solutions segment, certain businesses require a portion of the transaction price to be paid in advance of transfer of control. Advance payments are not considered a significant financing component as they are received less than one year before the related performance obligations are satisfied. In addition, in the Utility Solutions segment, certain businesses offer annual maintenance service contracts that require payment at the beginning of the contract period. These payments are treated as a contract liability and are classified in Other accrued liabilities in the Consolidated Balance Sheets. Once control transfers to the customer and the Company meets the revenue recognition criteria, the deferred revenue is recognized in the Consolidated Statements of Income. The deferred revenue relating to the annual maintenance service contracts is recognized in the Consolidated Statements of Income on a straight-line basis over the expected term of the contract.

The following table presents disaggregated revenue by business group. On January 1, 2022, we internally reorganized certain businesses within our Electrical Solutions segment to simplify the organization structure and align the organization to better serve our customers. This change had no impact to our reportable segments. In conjunction with this change, prior period amounts have been reclassified to conform to the organizational changes within the Electrical Solutions segment.

Contract Balances

Our contract liabilities consist of advance payments for products as well as deferred revenue on service obligations and extended warranties. The current portion of deferred revenue is included in Other accrued liabilities and the non-current portion of deferred revenue is included in Other non-current liabilities in the Consolidated Balance Sheet.

Contract liabilities were $45.8 million as of December 31, 2022 compared to $16.7 million as of December 31, 2021. The $29.1 million increase in our contract liabilities balance was primarily due to a $21.8 million net increase in current year deferrals primarily due to timing of advance payments on certain orders and a $20.1 million increase due to acquisitions, partially offset by the recognition of $12.8 million in revenue related to amounts that were recorded in contract liabilities at January 1, 2022. The Company has an immaterial amount of contract assets relating to performance obligations satisfied prior to payment that is recorded in Other long-term assets in the Condensed Consolidated Balance Sheets. Impairment losses recognized on our receivables and contract assets were immaterial in the twelve months ended December 31, 2022. See Note 1 – Significant Accounting Policies in the Notes to Consolidated Financial Statements for additional information.

Unsatisfied Performance Obligations

The Company has elected the practical expedient to disclose only the value of unsatisfied performance obligations for contracts with an original expected length greater than one year. As of December 31, 2022, the Company had approximately $320 million of unsatisfied performance obligations for contracts with an original expected length of greater than one year, primarily relating to long-term contracts of the Aclara business (within the Utility Solutions segment) to deliver and install meters, metering communications and grid monitoring sensor technology. The Company expects that a majority of the unsatisfied performance obligations will be completed and recognized over the next 2 years.

NOTE 4    Business Acquisitions and Dispositions

 

2022 Acquisitions

In the third quarter of 2022, the Company acquired all of the issued and outstanding membership interests of PCX Holdings LLC ("PCX") for a cash purchase price of approximately $112.8 million, net of cash acquired. PCX is a leading designer and manufacturer of factory built modular power solutions for applications in the data center market. This business is reported in the Electrical Solutions segment. We have recognized intangible assets of $49.1 million and goodwill of $77.4 million as a result of this acquisition. The intangible assets of $49.1 million consist primarily of customer relationships, backlog and a tradename and will be amortized over a weighted average period of approximately 11 years. All of the goodwill is expected to be deductible for tax purposes.

In the third quarter of 2022, the Company also acquired all of the issued and outstanding membership interests of Ripley Tools, LLC and Nooks Hill Road, LLC, collectively referred to as Ripley Tools, for a cash purchase price of approximately $50.1 million, net of cash acquired. Ripley Tools is a leading manufacturer of cable and fiber prep tools and test equipment that services both the utility and communications markets. This business is reported in the Utility Solutions segment. We have recognized intangible assets of $18.2 million and goodwill of $23.8 million as a result of this acquisition. The intangible assets of $18.2 million consist primarily of customer relationships and a tradename, and will be amortized over a weighted average period of approximately 17 years. Substantially all of the goodwill is expected to be deductible for tax purposes.

In the fourth quarter of 2022, the Company also acquired all of the issued and outstanding equity interests of REF Automation Limited and REF Alabama Inc. (collectively "REF") for a cash purchase price of $14.1 million, net of cash acquired, subject to customary purchase price adjustments. REF designs and manufactures electrical power components utilizing high-volume precision machining, as well as custom fabricated structural products and assemblies for the OEM, industrial and renewables markets. This business is reported in the Electrical Solutions segments. We have recognized goodwill of $10.2 million as a result of the acquisition. None of the goodwill associated with this acquisition is expected to be deductible for tax purposes.

These business acquisitions have been accounted for as business combinations and have resulted in the recognition of goodwill. The goodwill relates to a number of factors implied in the purchase prices, including the future earnings and cash flow potential of the businesses as well as the complementary strategic fit and resulting synergies that such business acquisitions bring to the Company’s existing operations.

Allocation of Consideration Transferred to Net Assets Acquired

The following table presents the determination of the fair value of identifiable assets acquired and liabilities assumed from the Company's 2022 acquisitions. Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact the Company's results of operations.

The following table summarizes the fair values of the assets acquired and liabilities assumed as of the respective date of acquisition for all transactions (in millions):

Tangible assets acquired			$	41.4
Intangible assets			67.3
Goodwill			111.4
Other liabilities assumed			(43.0)
Total Estimate of Consideration Transferred, Net of Cash Acquired			177.1

The Consolidated Financial Statements include the results of operations of the acquired businesses from their respective dates of acquisition. Net sales and earnings related to these acquisitions for the year ended December 31, 2022 were not significant to the consolidated results. Pro forma information related to these acquisitions has not been included because the impact to the Company's consolidated results of operations was not material.

Dispositions

In June of 2021, the Company completed the sale of the Consumer Analytics Solutions business for $9.8 million. The Consumer Analytics Solutions business was part of Aclara and was previously included in the Utility Solutions segment. Upon disposition, the Consumer Analytics Solutions business had assets of $15.9 million, including definite-lived intangibles of $8.7 million (primarily customer relationships and developed technology), goodwill of $1.9 million and total liabilities of $1.5 million (primarily composed of deferred revenue). As a result of the sale of the Consumer Analytics Solutions business, we recognized a pre-tax loss of $6.9 million that is included in Total other expense in the Consolidated Statement of Income.

Amortization expense associated with these definite-lived intangible assets was $75.7 million, $75.7 million and $72.1 million in 2022, 2021 and 2020, respectively. Amortization expense associated with these intangible assets is expected to be $71.2 million in 2023, $66.0 million in 2024, $63.6 million in 2025, $60.0 million in 2026 and $54.5 million in 2027. The Company amortizes intangible assets with definite lives using either an accelerated method that reflects the pattern in which economic benefits of the intangible assets are consumed and results in higher amortization in the earlier years of the assets' useful life, or using a straight line method. Approximately 80% of the gross value of definite-lived intangible assets follow an accelerated amortization method.

NOTE 12    Retirement Benefits

 

The Company has funded and unfunded non-contributory U.S. and foreign defined benefit pension plans. Benefits under these plans are generally provided based on either years of service and final average pay or a specified dollar amount per year of service. The U.S. defined benefit pension plan has been closed to new participants since 2004, while the Canadian and UK defined benefit pension plans have been closed to new entrants since 2006 and 2007, respectively. These U.S., Canadian and UK employees are eligible instead for defined contribution plans.

 

The Company also has a number of health care and life insurance benefit plans covering eligible employees who reached retirement age while working for the Company. These benefits have been discontinued for substantially all future retirees. The Company anticipates future cost-sharing charges for its discontinued plans that are consistent with past practices. The Company uses a December 31 measurement date for all of its plans.

In 2020 and 2022, the Company recognized a settlement loss in continuing operations relating to retirees that elected to receive lump-sum distributions from the Company's defined benefit pension plans of $7.6 million and $7.0 million, respectively. This charge was the result of lump-sum payments which exceeded the threshold for settlement accounting under U.S. GAAP in each year.

In 2019, the Company approved amendments to one of its domestic qualified defined benefit pension plans, which froze service accruals for nearly all active participants within the plan effective January 1, 2020. As a result of the amendment, the Company recognized a $0.3 million curtailment charge, net of tax. Effective January 1, 2020, the amortization of unrecognized gains and losses of all of the Company's qualified defined benefit pension plans is recognized over the remaining life expectancy of participants, as nearly all participants are considered inactive as a result of plan amendments.

The Company's U.S. defined benefit pension plans were approximately 90% of the $670.8 million total pension benefit obligations at December 31, 2022.

During 2022, the Company recognized $7.0 million of settlement losses in continuing operations and $1.8 million of settlement losses in discontinued operations. Those settlement losses are the result of lump-sum distributions from the Company's defined benefit pension plans which exceeded the threshold for settlement accounting under U.S. GAAP for the year.

The Company also maintains four primary defined contribution pension plans. The total cost of the Company's defined contribution plans was $25.8 million in 2022, $23.3 million in 2021 and $21.0 million in 2020, excluding the employer match for the 401(k) plan. This cost is not included in the above net periodic benefit cost for the defined benefit pension plans.

 

In 2020, 2021 and 2022 the Company participated in one multi-employer defined benefit pension plan. The Company’s total contributions while participating in this plan was $0.2 million in each of these years.

The risks of participating in multi-employer plans are different from single-employer plans in that assets contributed are pooled and may be used to provide benefits to employees of other participating employers. If a participating employer stops contributing to the plan, the unfunded obligations of the plan may have to be assumed by the remaining participant employers. If we choose to stop participating in a multi-employer plan we may be required to pay those plans a withdrawal liability based on the unfunded status of the plan.

Assumptions

 

The following assumptions were used to determine the projected benefit obligations at the measurement date and the net periodic benefit cost for the year:

			Pension Benefits												Other Benefits
			2022			2021			2020						2022			2021			2020
Weighted-average assumptions used to determine benefit obligations at December 31,
Discount rate			5.46		%	2.79		%	2.47		%				5.50		%	2.90		%	2.50		%
Rate of compensation increase			0.08		%	0.08		%	0.24		%				3.93		%	3.87		%	3.99		%
Weighted-average assumptions used to determine net periodic benefit cost for years ended December 31,
Discount rate			2.79		%	2.47		%	3.17		%				2.90		%	2.50		%	3.30		%
Expected return on plan assets			4.59		%	4.66		%	4.69		%				N/A			N/A			N/A
Rate of compensation increase			0.08		%	0.24		%	2.94		%				3.87		%	3.99		%	4.00		%

 

At the end of each year, the Company determines the appropriate expected return on assets for each plan based upon its strategic asset allocation (see discussion below). In making this determination, the Company utilizes expected returns for each asset class based upon current market conditions and expected risk premiums for each asset class.

 

The Company also determines the discount rate to be used to calculate the present value of pension plan liabilities at the end of each year. The discount rate for the Company’s U.S. and Canadian pension plans is determined by matching the expected cash flows associated with its benefit obligations to the expected cash flows of a hypothetical portfolio of high quality, fixed income debt instruments with maturities that closely match the expected funding period of its pension liabilities. As of December 31, 2022, the Company used a discount rate of 5.50% for its U.S. pension plans compared to a discount rate of 2.90% used in 2021. For its Canadian pension plan, the Company used a discount rate of 5.01% as of December 31, 2022 compared to a 2.98% discount rate used in 2021.

For its UK pension plan the discount rate was derived using a full yield curve and uses plan specific cash flows. The derived discount rate is the single discount rate equivalent to discounting these liability cash flows at the term-dependent spot rate of AA corporate bonds. This methodology resulted in a December 31, 2022 discount rate for the UK pension plan of 5.00% as compared to a discount rate of 1.80% used in 2021.

In 2020 we used the Pri-2012 mortality table to calculate the present value of our pension plan liabilities and adopted the MP-2020 projection scale, and in 2021 and 2022 we used the Pri-2012 mortality table and adopted the MP-2021 projection scale The Pri-2012 mortality table with adjustment for collar as appropriate and generational projection from 2012 using Scale MP-2021 was chosen as the best estimate based on the observed and anticipated experience of the plans after considering alternative tables. These changes did not have a material impact to the projected benefit obligation of our U.S. plans upon remeasurement.

 

The rate of compensation increase assumption reflects the Company’s actual experience and best estimate of future increases.

The assumed health care cost trend rates used to determine the projected postretirement benefit obligation are as follows: 

			Other Benefits
			2022			2021			2020
Assumed health care cost trend rates at December 31,
Health care cost trend assumed for next year			7.0		%	6.2		%	6.4		%
Rate to which the cost trend is assumed to decline			5.0		%	5.0		%	5.0		%
Year that the rate reaches the ultimate trend rate			2031			2028			2028

Plan Assets

 

The Company’s combined targeted 2023 weighted average asset allocation for domestic and foreign pension plans and the actual weighted average asset allocation for domestic and foreign pension plans at December 31, 2022 and 2021 by asset category are as follows: 

			Percentage of Plan Assets
			Target			Actual
Asset Category			2023			2022			2021
Equity securities			32		%	23		%	22		%
Debt securities & Cash			68		%	77		%	77		%
Alternative Investments			—		%	—		%	1		%
TOTAL			100		%	100		%	100		%

 

At the end of each year, the Company estimates the expected long-term rate of return on pension plan assets based on the strategic asset allocation for its plans. In making this determination, the Company utilizes expected rates of return for each asset class based upon current market conditions and expected risk premiums for each asset class. The Company has written investment policies and asset allocation guidelines for its domestic and foreign pension plans. In establishing these policies, the Company has considered that its various pension plans are a major retirement vehicle for most plan participants and has acted to discharge its fiduciary responsibilities with regard to the plans solely in the interest of such participants and their beneficiaries. The goal underlying the establishment of the investment policies is to provide that pension assets shall be invested in a prudent manner and so that, together with the expected contributions to the plans, the funds will be sufficient to meet the obligations of the plans as they become due.

 

To achieve this result, the Company conducts a periodic strategic asset allocation study to form a basis for the allocation of pension assets between various asset categories. Specific policy benchmark percentages are assigned to each asset category with minimum and maximum ranges established for each. The assets are then tactically managed within these ranges. Derivative investments include futures contracts used by the plan to adjust the level of its investments within an asset allocation category. The actual and target percentages reported in the preceding table reflect the economic exposure to each asset category, including the impact of derivative positions. All futures contracts are 100% supported by cash or cash equivalent investments. At no time may derivatives be utilized to leverage the asset portfolio. At December 31, 2022 and 2021, there were no holdings of Company stock in pension plan assets.

 

The Company’s other post-employment benefits are unfunded; therefore, no asset information is reported.

On March 12, 2021, the Company, as borrower, and its subsidiaries Hubbell Power Holdings S.à r.l. and Harvey Hubbell Holdings S.à r.l., each as a subsidiary borrower (collectively, the “Subsidiary Borrowers”), entered into a new five-year credit agreement with a syndicate of lenders and JPMorgan Chase, N.A., as administrative agent, that provides a $750 million committed revolving credit facility (the "2021 Credit Facility"). Commitments under the 2021 Credit Facility may be increased to an aggregate amount not to exceed $1.25 billion. The 2021 Credit Facility includes a $50 million sub-limit for the issuance of letters of credit. The sum of the dollar amount of loans and letters of credits to the Subsidiary Borrowers under the 2021 Credit Facility may not exceed $75 million.

The interest rate applicable to borrowings under the 2021 Credit Facility is either (i) the alternate base rate (as defined in the Revolving Credit Agreement) or (ii) the adjusted LIBOR rate (as defined in the 2021 Credit Facility) plus, in the case of this clause (ii), an applicable margin based on the Company’s credit ratings. All revolving loans outstanding under the 2021 Credit Facility will be due and payable on March 12, 2026.

The 2021 Credit Facility contains a financial covenant requiring that, as of the last day of each fiscal quarter, the ratio of total indebtedness to total capitalization shall not be greater than 65%.

On March 12, 2021, the Company completed a public offering of $300 million aggregate principal amount of its 2.300% Senior Notes due 2031 (the “2031 Notes”). The net proceeds from the offering were approximately $295.5 million after deducting the underwriting discount and estimated offering expenses payable by the Company. The Company used the net proceeds from the offering of the 2031 Notes, together with cash on hand, to redeem in full all of the Company’s outstanding 3.625% Senior Notes due 2022 in an aggregate principal amount of $300 million, which had a stated maturity date of November 15, 2022 (the “2022 Notes”), and to pay any premium and accrued interest in respect thereof, which redemption was completed on April 2, 2021. The redemption resulted in a $16.8 million loss on extinguishment of indebtedness that was recognized in the second quarter of 2021. The loss on extinguishment includes a cash premium of $16.0 million paid upon redemption in accordance with the terms of the 2022 Notes.

The 2031 Notes bear interest at a rate of 2.300% per annum from March 12, 2021. Interest on the 2031 Notes is payable semi-annually in arrears on March 15 and September 15 of each year, beginning on September 15, 2021. The 2031 Notes will mature on March 15, 2031.

The 2031 Notes are callable at any time with a make whole premium and are only subject to accelerated payment prior to maturity in the event of a default (including as a result of the Company's failure to meet certain non-financial covenants) under the indenture governing the notes or upon a change in control triggering event as defined in such indenture. The Company was in compliance with all non-financial covenants as of December 31, 2022.

In February 2018, the Company completed a public offering of $450 million of senior, unsecured, notes maturing in February 2028 and bearing interest at a fixed rate of 3.50% (the "2028 Notes"). Net proceeds from the issuance of the 2028 Notes were $442.6 million after deducting the discount on such notes and offering expenses paid by the Company. The 2028 Notes are callable at any time at specified prices and are only subject to accelerated payment prior to maturity upon customary events of a default under the indenture governing the 2028 Notes, as modified by the supplemental indenture creating such notes, or upon a change in control triggering event as defined in such indenture.

In August 2017, the Company completed a public debt offering of $300 million of long-term unsecured, unsubordinated notes maturing in August 2027 and bearing interest at a fixed rate of 3.15% (the "2027 Notes"). Net proceeds from the issuance were $294.6 million after deducting the discount on the notes and offering expenses paid by the Company.

In March 2016, the Company completed a public debt offering of $400 million of long-term unsecured, unsubordinated notes maturing in March 2026 and bearing interest at a fixed rate of 3.35% (the "2026 Notes"). Net proceeds from the issuance were $393.4 million after deducting the discount on the notes and offering expenses paid by the Company.

The 2026 Notes, 2027 Notes, 2028 Notes and 2031 Notes, are all fixed rate indebtedness, are callable at any time with a make whole premium and are only subject to accelerated payment prior to maturity in the event of a default (including as a result of the Company's failure to meet certain non-financial covenants) under the indenture governing the notes, as modified by the supplemental indentures creating such notes, or upon a change in control triggering event as defined in such indenture. The Company was in compliance with all non-financial covenants as of December 31, 2022.

 

At December 31, 2022 and 2021, the Company had no commercial paper borrowings outstanding and had $4.7 million and $9.7 million, respectively, of short-term debt outstanding composed of:

◦$2.8 million at December 31, 2022 and $1.6 million at December 31, 2021, respectively, of borrowings to support our international operations in China as well as $1.9 million and $8.1 million of other short term debt at December 31, 2022 and December 31, 2021, respectively, to support operations.

As of December 31, 2022, the Company had a total of $22.8 million of U.S. federal, state (net of federal benefit) and foreign tax credit carryforwards, available to offset future income taxes. As of December 31, 2022, $1.9 million of the tax credits may be carried forward indefinitely while the remaining $20.9 million will begin to expire at various times in 2023 through 2051. As of December 31, 2022, the Company had recorded tax benefits totaling $14.0 million for U.S. federal, state and foreign net operating loss carryforwards (“NOLs”). As of December 31, 2022, $5.5 million of NOLs may be carried forward indefinitely while the remaining $8.5 million will begin to expire at various times in 2023 through 2052. The tax benefit related to a portion of these NOLs has been adjusted to reflect an “ownership change” pursuant to Internal Revenue Code Section 382, which imposes an annual limitation on the utilization of pre-acquisition operating losses. The Company has recorded a net valuation allowance of $32.2 million on certain deferred tax assets including a portion of foreign and state tax credit carryforwards, capital loss carryforwards and NOLs that the Company anticipates will expire prior to utilization.

During 2022, the Company repatriated certain of its foreign earnings. As of December 31, 2022, the Company also anticipates repatriating certain of its foreign earnings in the future. The accompanying financial statements reflect the income tax expense associated with actual and anticipated remittances related to certain of our outside basis differences. The Company has not provided for the income tax effects of distributing the remaining approximately $400 million of undistributed foreign earnings as those amounts are either permanently reinvested or intended to be reinvested in our international operations. It is not practicable to estimate the tax cost associated with a remittance of such earnings.

Cash payments of income taxes were $168.0 million, $84.0 million and $96.2 million in 2022, 2021, and 2020, respectively.

The Company operates within multiple taxing jurisdictions and is subject to audit in these jurisdictions. The IRS and other tax authorities routinely audit the Company’s tax returns. These audits can involve complex issues which may require an extended period of time to resolve. In January 2023 the Company completed its 2018 U.S. federal tax examination with no material adjustments. With few exceptions, the Company is no longer subject to state, local, or income tax examinations by tax authorities for years prior to 2018.

The following tax years, by major jurisdiction, are still subject to examination by taxing authorities: 

Jurisdiction			Open Years
United States			2019-2022
UK			2021-2022
Puerto Rico			2018-2022
Canada			2018-2022

 

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in millions): 

			2022			2021			2020
Unrecognized tax benefits at beginning of year			$	41.2		$	47.6		$	41.9
Additions based on tax positions relating to the current year			12.1			6.1			7.4
Reductions based on expiration of statute of limitations			(4.8)			(10.3)			(6.2)
Additions/(Subtractions) to tax positions relating to previous years			(6.2)			(2.2)			4.5
Settlements			(0.2)			—			—
TOTAL UNRECOGNIZED TAX BENEFITS			$	42.1		$	41.2		$	47.6

 

Included in the balance at December 31, 2022 are approximately $33.9 million of tax positions which, if in the future are determined to be recognizable, would affect the annual effective income tax rate. Additionally, there are $4.3 million of tax positions for which the ultimate deductibility is highly certain but for which there is uncertainty as to the timing of such deductibility. Because of the impact of deferred tax accounting, other than interest and penalties, the disallowance of the shorter deductibility period would not affect the annual effective tax rate but would accelerate the payment of cash to the applicable taxing authority to an earlier period. It is reasonably possible that in the next twelve months, because of changes in facts and circumstances, the unrecognized tax benefits may increase or decrease.

The Company estimates a possible decrease of approximately $5 million to $11 million within the next twelve months due to the expiration of the statute of limitations and audit resolutions.

 

The Company’s policy is to record interest and penalties associated with the underpayment of income taxes within Provision for income taxes in the Consolidated Statement of Income. The Company recognized (benefit) expense, before federal tax impact, related to interest and penalties of $(1.0) million in 2022, $0.3 million in 2021 and $0.2 million in 2020. The Company had $6.7 million and $7.6 million accrued for the payment of interest and penalties as of December 31, 2022 and December 31, 2021, respectively.

 

The consolidated effective income tax rate varied from the United States federal statutory income tax rate of continuing operations for the years ended December 31, as follows:

			2022			2021			2020
Federal statutory income tax rate			21.0		%	21.0		%	21.0		%
State income taxes, net of federal benefit			2.4			2.5			2.9
Foreign income taxes			(0.2)			(0.5)			(0.2)
Federal R&D Credit			(0.8)			(1.4)			(1.3)
Other, net			(1.1)			(2.4)			(1.2)
CONSOLIDATED EFFECTIVE INCOME TAX RATE			21.3		%	19.2		%	21.2		%

 

The foreign income tax benefit shown is primarily due to lower statutory rates in foreign jurisdictions compared to the United States federal statutory income tax rate.

NOTE 15    Financial Instruments and Fair Value Measurement

 

Financial Instruments

Concentrations of Credit Risk: Financial instruments which potentially subject the Company to significant concentrations of credit risk consist of trade receivables, cash equivalents and investments. The Company grants credit terms in the normal course of business to its customers. Due to the diversity of its product lines, the Company has an extensive customer base including electrical distributors and wholesalers, electric utilities, equipment manufacturers, electrical contractors, telecommunication companies and retail and hardware outlets. We are not dependent on a single customer, however, the Company’s top ten customers account for approximately 43% of its Net sales. As part of its ongoing procedures, the Company monitors the credit worthiness of its customers. Bad debt write-offs have historically been minimal. The Company places its cash and cash equivalents with financial institutions and limits the amount of exposure in any one institution.

At December 31, 2022 our accounts receivable balance was $741.6 million, net of allowances of $14.3 million. The allowance for doubtful accounts has not materially changed since December 31, 2021.

Fair Value: The carrying amounts reported in the Consolidated Balance Sheet for cash and cash equivalents, short-term investments, receivables, bank borrowings, accounts payable and accruals approximate their fair values given the immediate or short-term nature of these items. See also Note 8 — Investments.

Fair value measurements

At December 31, 2022 and 2021 the Company had $80.2 million and $78.5 million respectively, of investments carried on the balance sheet at fair value. Fair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The FASB fair value measurement guidance established a fair value hierarchy that prioritizes the inputs used to measure fair value. Refer to Note 8 — Investments for more information about these investments.

The three broad levels of the fair value hierarchy are as follows:

 

Level 1 -     Quoted prices (unadjusted) in active markets for identical assets or liabilities

Level 2 -     Quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly

Level 3 -     Unobservable inputs for which little or no market data exists, therefore requiring a company to develop its own assumptions

The following tables show, by level within the fair value hierarchy, the Company’s financial assets and liabilities that are accounted for at fair value on a recurring basis at December 31, 2022 and 2021 (in millions):

Asset (Liability)			Quoted Prices in Active Markets for Identical Assets (Level 1)			Quoted Prices in Active Markets for Similar Assets (Level 2)			Unobservable inputs for which little or no market data exists (Level 3)			Total

Forward exchange contracts-Assets (b)			—			0.5			—			0.5
BALANCE AT DECEMBER 31, 2021			$	58.5		$	54.5		$	—		$	113.0

(a)Money market funds and time deposits are included in Cash and cash equivalents in the Consolidated Balance Sheet.

(b)Forward exchange contracts-Assets are reflected in Other current assets in the Consolidated Balance Sheet.

The methods and assumptions used to estimate the Level 2 fair values were as follows:

 

Forward exchange contracts – The fair value of forward exchange contracts were based on quoted forward foreign exchange prices at the reporting date.

Available-for-sale municipal bonds classified in Level 2 – The fair value of available-for-sale investments in municipal bonds is based on observable market-based inputs, other than quoted prices in active markets for identical assets. 

Deferred compensation plan

The Company offers certain employees the opportunity to participate in non-qualified deferred compensation plans. A participant’s deferrals are invested in a variety of participant-directed debt and equity mutual funds that are classified as trading securities. During 2022 and 2021, the Company purchased $2.2 million and $2.7 million, respectively, of trading securities related to these deferred compensation plans. As a result of participant distributions, the Company sold $4.2 million and $3.6 million of these trading securities in 2022 and 2021 respectively. The unrealized gains and losses associated with these trading securities are directly offset by the changes in the fair value of the underlying deferred compensation plan obligation.

Long-term Debt

 

As of December 31, 2022 and December 31, 2021, the carrying value of long-term debt, net of unamortized discount and debt issuance costs, was $1,437.9 million and $1,435.5 million, respectively. The estimated fair value of the long-term debt as of December 31, 2022 and December 31, 2021 was $1,306.5 million and $1,524.5 million, respectively, using quoted market prices in active markets for similar liabilities (Level 2).

NOTE 16    Commitments and Contingencies

Legal and Environmental

 

The Company is subject to various legal proceedings arising in the normal course of its business. These proceedings include claims for damages arising out of use of the Company’s products, intellectual property, workers’ compensation and environmental matters. The Company is self-insured up to specified limits for certain types of claims, including product liability and workers’ compensation, and is fully self-insured for certain other types of claims, including environmental and intellectual property matters. The Company recognizes a liability for any contingency that in management’s judgment is probable of occurrence and can be reasonably estimated. We continually reassess the likelihood of adverse judgments and outcomes in these matters, as well as estimated ranges of possible losses based upon an analysis of each matter which includes advice of outside legal counsel and, if applicable, other experts.

The Company is subject to environmental laws and regulations which may require that it investigate and remediate the effects of potential contamination associated with past and present operations as well as those acquired through business combinations. Environmental liabilities are recorded when remedial efforts are probable and the costs can be reasonably estimated. The Company continues to monitor these environmental matters and revalues its liabilities as necessary. Total environmental liabilities were $6.3 million and $6.4 million as of December 31, 2022 and 2021, respectively.

The Company accounts for conditional asset retirement and environmental obligations in accordance with the applicable accounting guidance. The accounting guidance defines “conditional asset retirement obligation” as a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the Company. Accordingly, an entity is required to recognize a liability for the fair value of a conditional asset retirement obligation if the fair value of the liability can be reasonably estimated. Asset retirement obligations were not material as of December 31, 2022 and 2021.

NOTE 18    Stock-Based Compensation

 

As of December 31, 2022, the Company had various stock-based awards outstanding which were issued to executives and other key employees. The Company recognizes the grant-date fair value of all stock-based awards to employees over their respective requisite service periods (generally equal to an award’s vesting period), net of estimated forfeitures. A stock-based award is considered vested for expense attribution purposes when the employee’s retention of the award is no longer contingent on providing subsequent service. For those awards that vest immediately upon retirement eligibility, the Company recognizes compensation cost immediately for retirement-eligible individuals or over the period from the grant date to the date retirement eligibility is achieved, if less than the stated vesting period.

 

The Company’s long-term incentive program for awarding stock-based compensation includes a combination of restricted stock, stock appreciation rights (“SARs”), and performance shares of the Company’s common stock pursuant to the Award Plan. Under the Award Plan, the Company may authorize up to 9.7 million shares of common stock to settle awards of restricted stock, performance shares, or SARs. The Company issues new shares to settle stock-based awards. In 2022, the Company's grant of stock-based awards included restricted stock, SARs and performance shares.

Stock-based compensation expense recognized by the Company was $24.5 million in 2022, $17.5 million in 2021 and $21.9 million in 2020. The total income tax benefit recognized was $3.9 million in 2022, $3.2 million in 2021, and $3.2 million in 2020. The net tax windfall recorded as a result of exercise or vesting (depending on the type of award) was $3.2 million, $6.8 million, and $3.4 million in 2022, 2021 and 2020, respectively. As of December 31, 2022, there was $18.1 million, pretax, of total unrecognized compensation cost related to non-vested share-based compensation arrangements. This cost is expected to be primarily recognized through 2025.

Stock-based compensation expense is recorded in S&A expense as well as Cost of goods sold. Of the total 2022 expense, $23.2 million was recorded to S&A expense and $1.3 million was recorded to Cost of goods sold. In 2021 and 2020, $15.8 million and $20.4 million, respectively, was recorded to S&A expense and $1.7 million and $1.5 million, respectively, was recorded to Cost of goods sold. Stock-based compensation costs capitalized to inventory was $0.4 million in each of 2022, 2021 and 2020.

Each of the compensation arrangements is discussed below.

Restricted Stock  

The Company issues various types of restricted stock awards all of which are considered outstanding at the time of grant, as the award holders are entitled to dividends and voting rights. Unvested restricted stock awards are considered participating securities when computing earnings per share. Restricted stock grants are not transferable and are subject to forfeiture in the event of the recipient’s termination of employment prior to vesting.

Restricted Stock Issued to Employees - Service Condition

 

Restricted stock awards that vest based upon a service condition are expensed on a straight-line basis over the requisite service period. These awards generally vest either in three equal installments on each of the first three anniversaries of the grant date or on the third year anniversary of the grant date. The fair value of these awards is measured by the average of the high and low trading prices of the Company’s common stock on the most recent trading day immediately preceding the grant date (“measurement date”).

Restricted Stock Issued to Non-employee Directors

 

In 2022, 2021 and 2020, each non-employee director received a restricted stock grant. These grants are made on the date of the annual meeting of shareholders and vest at the following year’s annual meeting of shareholders, or upon certain other events. The grant is subject to forfeiture if the director’s service terminates prior to the date of the next regularly scheduled annual meeting of shareholders. During 2022, 2021 and 2020, the Company granted 5,952 shares, 6,741 shares, and 7,413 shares, respectively, to non-employee directors.

Restricted Stock Issued to Employees and Non-employee Directors

Activity related to both employee and non-employee restricted stock for the year ended December 31, 2022 is as follows (in thousands, except per share amounts):

			Shares			Weighted Average Grant Date Fair Value/Share
RESTRICTED STOCK AT DECEMBER 31, 2021			184			$	141.99
Shares granted			64			187.07
Shares vested			(56)			148.93
Shares forfeited			(13)			163.54
RESTRICTED STOCK AT DECEMBER 31, 2022			179			$	154.09

 

The weighted average fair value per share of restricted stock granted in 2022, 2021 and 2020 was $187.07, $166.46 and $145.48, respectively. The total fair value of restricted stock vested in 2022, 2021 and 2020 was $8.4 million, $12.6 million and $7.8 million, respectively.

 

Stock Appreciation Rights

SARs grant the holder the right to receive, once vested, the value in shares of the Company's common stock equal to the positive difference between the grant price, as determined using the mean of the high and low trading prices of the Company’s common stock on the measurement date, and the fair market value of the Company’s common stock on the date of exercise. This amount is payable in shares of the Company’s common stock. SARs vest and become exercisable in three equal installments during the first three years following the grant date and expire ten years from the grant date.

 

Activity related to SARs for the year ended December 31, 2022 is as follows (in thousands, except per share amounts):

			Number of Rights			Weighted Average Exercise Price			Weighted Average Remaining Contractual Term			Aggregate Intrinsic Value
OUTSTANDING AT DECEMBER 31, 2021			907			$	132.78
Granted			143			186.62
Exercised			(245)			122.49
Forfeited			(26)			170.12
Canceled			—			—
OUTSTANDING AT DECEMBER 31, 2022			779			$	144.66		6.8 years			$	70,146
EXERCISABLE AT DECEMBER 31, 2022			452			$	127.44		5.7 years			$	48,506

 

The aggregated intrinsic value of SARs exercised during 2022, 2021 and 2020 was $21.0 million, $46.8 million and $20.2 million, respectively.

 

The fair value of each SAR award was measured using the Black-Scholes option pricing model.

The following table summarizes the weighted-average assumptions used in estimating the fair value of the SARs granted during the years 2022, 2021 and 2020:

Grant Date			Expected Dividend Yield			Expected Volatility			Risk Free Interest Rate			Expected Term			Weighted Avg. Grant Date Fair Value of 1 SAR
2022			2.1		%	27.4		%	1.9		%	4.9 years			$	39.68
2021			2.4		%	26.5		%	0.6		%	5.5 years			$	29.58
2020			2.5		%	23.5		%	1.3		%	5.5 years			$	24.52

 

The expected dividend yield was calculated by dividing the Company’s expected annual dividend by the average stock price for the past three months. Expected volatilities are based on historical volatilities of the Company’s stock for a period consistent with the expected term. The expected term of SARs granted was based upon historical exercise behavior of SARs. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the award.

Performance Shares

Performance shares represent the right to receive a share of the Company’s common stock subject to the achievement of certain market or performance conditions established by the Company’s Compensation Committee and measured over a three year period. Partial vesting in these awards may occur after separation from the Company for retirement eligible employees. Shares are not vested until approved by the Company’s Compensation Committee.

Performance Shares - Performance and Market Conditions

In February 2020 and December 2018, the Company granted performance share awards with a target payout of 63,868 and 60,008 shares, respectively, that will vest subject to a performance condition and service requirement. The number of shares vested is then modified by a market condition as described below.

Thirty-four percent of the award granted will vest based on Hubbell’s compounded annual growth rate of Net sales as compared to that of the companies that comprise the S&P Capital Goods 900 index. Thirty-three percent of the award granted will vest based on achieved operating margin performance as compared to internal targets, and thirty-three percent of the award granted will vest based on achieved trade working capital as a percent of Net sales as compared to internal targets. Each of these performance conditions is measured over the same three-year performance period. The cumulative result of these performance conditions can result in a number of shares earned in the range of 0% - 200% of the target number of shares subject to the award. That cumulative performance achieved is then further modified based on the Company's three year TSR relative to the companies that constitute the S&P Capital Goods 900 index, to potentially increase or reduce the shares earned by a multiple of up to 1.5 or 1.2, depending on the award year.

The fair value of the award was determined based upon a lattice model. The Company expenses these awards on a straight-line basis over the requisite service period which includes an assessment of the performance achieved to date. The weighted average fair value per share was $151.78 for the awards granted in 2020 and $98.80 for the awards granted in 2018.

Grant Date			Shares Outstanding at 12/31/2022			Fair Value			Performance Period						Payout Range
2020			43,949			$	151.78		Jan 2020-Dec 2022						0-200% + up to a multiple of 150x
2018			—			$	98.80		Jan 2019-Dec 2021						0-200% + up to a multiple of 120x

During 2022, approximately 38,000 shares from the 2018 awards vested as a result of the cumulative achievement of the performance metrics, and the fair value of the awards at vesting was approximately $7.3 million.

Performance Shares - Market Condition

 

In February 2022 and 2021, the Company granted performance share awards with a target payout of 14,076 and 15,741 shares, respectively, that will vest subject to a market condition and service condition through the performance period. The market condition associated with the awards is the Company's total shareholder return ("TSR") compared to the TSR generated by the companies that comprise the S&P Capital Goods 900 index over a three year performance period. Performance at target will result in vesting and issuance of the number of performance shares subject to the award, equal to 100% payout. Performance below or above target can result in issuance in the range of 0%-200% of the number of shares subject to the award. Expense is recognized irrespective of the market condition being achieved.

The fair value of the performance share awards with a market condition for these grants was determined based upon a lattice model. The following table summarizes the related assumptions used to determine the fair values of the performance share awards with a market condition granted during February 2022 and 2021:

Grant Date			Stock Price on Measurement Date			Dividend Yield			Expected Volatility			Risk Free Interest Rate			Expected Term			Weighted Avg. Grant Date Fair Value
February 2022			$185.87			2.3%			39.7%			1.6%			2.9 years			$221.94
February 2021			$163.26			2.4%			40.6%			0.2%			3 years			$198.89

Expected volatilities are based on historical volatilities of the Company's and members of the peer group's stock over the expected term of the award. The risk free interest rate is based on the U.S. Treasury yield curve in effect at the time of the grant for the expected term of the award.

Performance Shares - Performance Condition

In February 2022 and 2021, the Company granted performance share awards with a target payout of 28,628 and 31,543 shares, respectively, that will vest subject to an internal Company-based performance condition and service requirement.

HUBBELL INCORPORATED - Form 10-K			81

---

Fifty percent of these performance shares subject to the award will vest based on Hubbell's compounded annual growth rate of Net sales as compared to that of the companies that comprise the S&P Capital Goods 900 index. Fifty percent of these performance shares subject to the award will vest based on achieved operating profit margin performance as compared to internal targets. Each of these performance conditions is measured over the same three-year performance period. The cumulative result of these performance conditions can result in a number of shares earned in the range of 0%-200% of the target number of shares subject to the award.

The fair value of the award is measured based upon the average of the high and low trading prices of the Company's common stock on the measurement date reduced by the present value of dividends expected to be paid during the requisite service period. The Company expenses these awards on a straight-line basis over the requisite service period and including an assessment of the performance achieved to date. The weighted average fair value per share was $174.48 and $151.92 for the awards granted in 2022 and 2021, respectively.

NOTE 19    Earnings Per Share

 

The Company computes earnings per share using the two-class method, which is an earnings allocation formula that determines earnings per share for common stock and participating securities. Restricted stock granted by the Company is considered a participating security since it contains a non-forfeitable right to dividends.

NOTE 22    Guarantees

 

The Company records a liability equal to the fair value of guarantees in the Consolidated Balance Sheet in accordance with the accounting guidance for guarantees. When it is probable that a liability has been incurred and the amount can be reasonably estimated, the Company accrues for costs associated with guarantees. The most likely costs to be incurred are accrued based on an evaluation of currently available facts and, where no amount within a range of estimates is more likely, the minimum is accrued.

 

As of December 31, 2022, the fair value and maximum potential payment related to the Company’s guarantees were not material.

 

The Company offers product warranties which cover defects on most of its products. These warranties primarily apply to products that are properly installed, maintained and used for their intended purpose. The Company accrues estimated warranty costs at the time of sale. Estimated warranty expenses, recorded in cost of goods sold, are based upon historical information such as past experience, product failure rates, or the estimated number of units to be repaired or replaced. Adjustments are made to the product warranty accrual as claims are incurred, additional information becomes known or as historical experience indicates.

 

Changes in the accrual for product warranties in 2022 are set forth below (in millions):

BALANCE AT DECEMBER 31, 2020			$	72.7
Provision			8.8
Expenditures/other			(15.4)

NOTE 23    Restructuring Costs

During 2022, we incurred costs for restructuring actions initiated in 2022 as well as costs relating to restructuring actions initiated in the prior year. Our restructuring actions are associated with cost reduction efforts that include the consolidation of manufacturing and distribution facilities, as well as, workforce reductions and the sale or exit of business units we determine to be non-strategic. Restructuring costs are primarily severance and employee benefits, asset impairments, as well as facility closure, contract termination and certain pension costs that are directly related to restructuring actions. These costs are predominantly settled in cash from our operating activities and are generally settled within one year, with the exception of asset impairments, which are non-cash.

NOTE 24    Leases

Our operating leases primarily consist of office space, certain manufacturing facilities, and vehicles. Our finance leases are not material. The term of our operating leases is generally 10 years or less, in some cases, with options to extend the term for up to 5 years, or options to terminate after one year without penalty. In general, our vehicle lease payments contain a monthly base rent payment which is adjusted based on changes to the LIBOR rate over the lease term. Certain other lease agreements contain variable payments related to a consumer price index or similar metric. Any change in payment amounts as a result of a change in a rate or index are considered variable lease payments and recognized as profit or loss when incurred.

Rent expense for operating leases in the Consolidated Statements of Income for the years ended December 31, 2022, December 31, 2021, and December 31, 2020 were $35.7 million, $34.1 million, and $35.5 million, respectively. Cash paid for operating leases for the year ended December 31, 2022 and December 31, 2021 were $36.3 million and $36.7 million reported as cash outflows from operating activities in the Consolidated Statements of Cash Flows. Right-of-use ("ROU") assets obtained in exchange for lease obligations for the year ended December 31, 2022 and December 31, 2021 were $58.9 million and $17.8 million, respectively, which includes $7.4 million related to acquisitions in 2022.

Amounts recognized for operating leases in the Consolidated Balance Sheets is as follows (in millions):

						December 31, 2022			December 31, 2021
Operating lease right-of-use assets						$	108.0		$	81.3
TOTAL ASSETS						$	108.0		$	81.3
Other accrued liabilities						$	30.5		$	27.1
Other non-current liabilities						84.9			58.3
TOTAL LIABILITIES						$	115.4		$	85.4

The weighted average remaining lease term as of December 31, 2022 and December 31, 2021 for operating leases were 5.5 and 4 years, respectively. The weighted average discount rate used to measure the ROU asset and lease liability for operating leases was 3.2% as of December 31, 2022 and 2.7% as of December 31, 2021.

Future maturities of our operating lease liabilities as of December 31, 2022 are as follows (in millions):

ITEM 9    Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

Not applicable.

ITEM 9A    Controls and Procedures

 

The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Management necessarily applied its judgment in assessing the costs and benefits of such controls and procedures which, by their nature, can provide only reasonable assurance that the controls and procedures will meet their objectives.

During the year ended December 31, 2022, the Company acquired PCX Holdings LLC, Ripley Tools, LLC and Nooks Hill Road, LLC, and REF Automation Limited and REF Alabama Inc. for an aggregate of $177.1 million. Because the Company has not yet fully incorporated the internal controls and procedures of the acquired entities into the Company's internal control over financial reporting, management excluded these business from its assessment of the effectiveness of internal control over financial reporting as of December 31, 2022. These entities accounted for 2% of the Company's total assets excluding intangibles and goodwill as of December 31, 2022 and less than 1% of the Company's net sales for the year then ended December 31, 2022.

The Company carried out an evaluation, under the supervision and with the participation of management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as defined in Exchange Act Rules 13a-15(e) and 15d-15(e), as of the end of the period covered by this report on Form 10-K. Based upon that evaluation, each of the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures are effective at a reasonable assurance level. Management’s annual report on internal control over financial reporting and the independent registered public accounting firm’s audit report on the effectiveness of our internal control over financial reporting as of December 31, 2022 are included in Item 8 of this Annual Report on Form 10-K.

There has been no change in the Company’s internal control over financial reporting that occurred during the fiscal year ended December 31, 2022 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

HUBBELL INCORPORATED

PERFORMANCE SHARE AWARD

HUBBELL INCORPORATED 2005 INCENTIVE AWARD PLAN,

AS AMENDED AND RESTATED

Grant Date: [Grant Date]
Performance Period: January 1, 2020 – December 31, 2022

As noted in your Award notification letter, effective on the Grant Date, Hubbell Incorporated (the “Company”) has granted to you an award (the “Award”) of Performance Shares (the “Performance Shares”) in the amount set forth in your Award notification letter, which is your “target.” Each Performance Share represents the right to receive a share of the Company’s Common Stock (the “Common Stock”) subject to the fulfillment of the conditions set forth below. This Award is made pursuant to the terms of the Hubbell Incorporated 2005 Incentive Award Plan, as amended and restated (the “Plan”) and is subject to all of the terms and conditions contained therein. By electronically acknowledging and accepting this Award, you agree to be bound by the terms and conditions herein, the Plan, and any and all conditions established by the Company in connection with Awards issued under the Plan. Defined terms used herein shall have the meaning set forth in the Plan, unless otherwise defined herein.

On any date, one Performance Share has a value equal to the Fair Market Value of one share of Common Stock. Unless and until a Performance Share is earned, you will have no right to any shares of Common Stock. Prior to actual payment, vested Performance Shares represent only an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company.

The number of Performance Shares actually earned, and therefore the number of shares of Common Stock to be delivered will be measured as of the last day of the Performance Period according to Exhibit A hereto; provided, however, that no Performance Shares shall become earned and payable unless and until the Compensation Committee of the Board of Directors of the Company certifies that the performance criteria set forth on Exhibit A hereto have been met. Notwithstanding the foregoing, the target number of Performance Shares will be considered earned and Common Stock equivalent to the target will be payable upon your death or Permanent Disability while employed with the Company during the Performance Period. “Permanent Disability” as used in this Agreement means that you are unable to perform your duties by reason of any medically determined physical or mental impairment which can be expected to result in death or which has lasted or is expected to last for a continuous period of at least 12 months such that you are “disabled” within the meaning of Section 1.409A-3(i)(4) of the Treasury regulations, as reasonably determined by the Board of Directors in its discretion. In the case of a Change in Control, the number of Performance Shares actually earned and therefore the number of shares of Common Stock to be delivered will be determined in accordance with Section 10.2 of the Plan.

If during the Performance Period your termination of employment is (a) other than by reason of death, following your Permanent Disability or for Cause and (b) on or after age 55 and the sum

---

of your age and service with the Company equals or exceeds 70 (a “Retirement”) you will be eligible to receive the number of Performance Shares you would have received if you had not retired prior to the end of the Performance Period multiplied by a fraction, the denominator of which is 36 and the numerator of which is the number of months elapsed during the Performance Period to the date of your Retirement. For this purpose “Cause” means (i) misconduct which is reasonably deemed to be prejudicial to the interest of the Company, (ii) utilization or disclosure of confidential information of the Company (or of any other entity learned in the course of your job) for reasons unrelated to your employment with the Company, (iii) willful failure to perform the material duties of your job, (iv) fraud in connection with the business affairs of the Company regardless of whether said conduct is designed to defraud the Company or otherwise, (v) violation of the code of conduct or material policies of the Company including, but not limited to, written policies related to discrimination, harassment, performance of illegal or unethical activities, or conflicts of interest, (vi) violation of any fiduciary duty owed to the Company, or (vii) conviction of, plea of no contest or guilty to a felony or other crime involving moral turpitude. Cause shall be determined by the Committee (or such officer of the Company as the Committee may delegate such authority) in its sole and exclusive discretion.

In the event of the termination of your employment or service with the Company and all of its Subsidiaries for any reason other than your death or Retirement or following your Permanent Disability, whether such termination is occasioned by you, by the Company or any of its Subsidiaries, with or without Cause or by mutual agreement prior to the last day of the Performance Period, you will forfeit all rights to the Performance Shares.

Once a Performance Share is considered earned and payable, the Company will cause to be issued the appropriate number of shares of Common Stock payable thereunder. Such shares will be issued in book form, unless you request the shares be issued in certificate form. Shares of Common Stock shall be issued, including in the event of your Retirement, during the calendar year following the calendar year in which the Performance Period ends, generally within the first 120 days of such calendar year, other than in the case of your death or Permanent Disability, in which case the shares of Common shall be issued within thirty (30) days following such event. In the case of a Change in Control, payment of earned and payable Performance Shares will be determined in accordance with Section 10.2 of the Plan.

The Company has the authority to deduct or withhold, or require you to remit to the Company, an amount sufficient to satisfy applicable federal, state, local and foreign taxes (including your FICA obligation) required by law to be withheld with respect to any taxable event arising from this Award. You may satisfy your tax obligation, in whole or in part, by either: (i) electing to have the Company withhold shares of Common Stock otherwise to be delivered with a Fair Market Value equal to the minimum amount of the tax withholding obligation, (ii) surrendering to the Company previously owned shares of Common Stock with a Fair Market Value equal to the minimum amount of the tax withholding obligation, (iii) withholding from other cash compensation, (iv) paying the amount of the tax withholding obligation directly to the Company in cash, or (v) a combination of the foregoing; provided, however, that if the tax obligation arises during a period in which you are prohibited from trading under any policy of the Company or by reason of the Exchange Act, then the tax withholding obligation shall automatically be satisfied

---

by the Company withholding shares of Common Stock otherwise to be delivered with a Fair Market Value equal to the minimum amount of the tax withholding obligation.

The Performance Shares or any right or interest therein or part thereof are not transferable except by will or the laws of descent and distribution. Until delivery of the Common Stock upon payment of the Performance Shares, you have no rights or privileges of a stockholder of the Company by reason of this Award. Nothing in the Plan or this Agreement shall be interpreted to interfere with or limit in any way the right of the Company or any Subsidiary to terminate your services at any time, nor confer upon you the right to continue in the service of the Company or any Subsidiary.

This Award of Performance Shares is granted under and governed by the terms and conditions of the Plan. You acknowledge and agree that the Plan has been introduced voluntarily by the Company and in accordance with its terms it may be amended, cancelled, or terminated by the Company, in its sole discretion, at any time. The grant of this Award of Performance Shares under the Plan is a one-time benefit and does not create any contractual or other right to receive awards of performance shares or other benefits in lieu of performance shares in the future. Future awards of performance shares, if any, will be at the sole discretion of the Company, including, but not limited to, the timing of the award, the number of shares and vesting provisions.

You acknowledge and agree to comply with the following covenants (the “Restrictive Covenants”), each of which is individually a material term of this Award and is a condition precedent to the Company making this Award, and is in addition to, and not in lieu of, any other restrictive covenants between you and the Company or any of its affiliates:

(i) You acknowledge that you have and will have possession of or access to apparatus, equipment, drawings, reports, manuals, invention records, customer lists, computer programs, or other material embodying trade secrets or confidential technical or business information of the Company (“Confidential Information”). You agree (a) not to use any such Confidential Information or material for yourself or others, and (b) not to take any such Confidential Information or reproductions of all or any portion thereof from Company facilities, in any case at any time during or after your employment by or service to the Company, except as required in your duties to the Company. You agree immediately to return all such Confidential Information and reproductions thereof in your possession to the Company upon request and in any event, upon termination of employment or service. Except with prior written authorization by the Company, you further agree not to disclose or publish any trade secret or Confidential Information of the Company or of another party to whom the Company owes an obligation of confidence, at any time during or after your employment by or service to the Company.

(ii) You agree that while providing services to the Company, you had and/or will have contact with and become aware of some, most or all of the customers of the Company, representatives of those customers, their names and addresses, specific customer and supplier needs and requirements, and leads and references to prospective customers. You agree that during the period of your employment or service with the Company and for the period beginning on the date of your termination of employment or service with the Company for any reason (the “Date

---

of Termination”) and ending on the twelve-month anniversary thereof (such period, the “Restricted Period”), you will not directly or indirectly (a) solicit any person or entity to whom the Company has provided products or services, or any person or entity whom the Company is actively soliciting to provide products or services as of the Date of Termination, for the purpose of providing any product or service that is competitive with any product or service then offered by the Company or (b) accept business from any person or entity to whom the Company has provided products or services in the two (2) years immediately prior to the Date of Termination, where such acceptance of business concerns any product or service that is competitive with any product or service then offered by the Company. The restrictions set forth in this paragraph shall only apply to any person or entity with whom you had contact or about whom you received confidential information during the two (2) years immediately prior to the Date of Termination. For purposes of this paragraph, “contact” means interaction between you and the person or entity which takes place to further the business relationship with the Company, or performing services for the person or entity on behalf of the Company.

(iii) You agree that during the Restricted Period, you will not directly or indirectly solicit, recruit, hire or attempt to recruit or hire any other employee of the Company with whom you had contact during your employment with the Company. For purposes of this paragraph, “contact” means any interaction whatsoever between you and the other employee related to the Company.

(iv) You agree to the following restrictions: (a) during the Restricted Period, you will not, within the defined “geographic region,” directly or indirectly own, manage, operate, join or control or participate in the ownership management, operation or control of, or become a director or employee of, or a consultant to, any person, firm, or entity selling or distributing products that are competitive with the products you worked on during the two years immediately prior to the Date of Termination (each, a “Competitor”). For the purposes of this paragraph, if you were assigned a geographic territory while employed by or providing services to the Company, the term “geographic region” shall mean the countries, states, provinces, and/or cities within any geographic territory assigned to you within the two years immediately prior to the Date of Termination. For the purposes of this paragraph, if you were not assigned a geographic territory (such as for engineers or management personnel) the term “geographic region” shall mean (i) any countries, states, provinces, and/or cities where the Company sold or distributed the products you worked on or for which you were responsible during the two years immediately prior to the Date of Termination, or, if a court deems this geographic region overly broad, then (ii) the United States, or if a court deems this geographic region overly broad, then (iii) the state state(s) in which you regularly worked during the two years immediately prior to the Date of Termination.

(v) In the event you believe your activity in violation of these Restrictive Covenants would not harm the Company’s legitimate business interests, you may request that the Company waive the restrictions contained in this paragraph. Any such request shall be made in writing to the Company, c/o Hubbell Incorporated, 40 Waterview Drive, Shelton, CT 06484-1000, Attention: General Counsel, and shall identify the business with whom/which you seek to associate and describe the duties that you seek to perform. The Company has the sole discretion whether to

---

grant such a waiver and no waiver of any restrictions under this provision shall be effective unless in writing and signed by an authorized representative of the Company.

(vi) You agree that the time, geographic, and scope limitations of the Restrictive Covenants are reasonable and necessary to protect the Company’s confidential information, trade secrets, and goodwill.

(vii) The terms of the Restrictive Covenants are severable. Any term or provision of the Restrictive Covenants that is held to be invalid or unenforceable shall be ineffective to the extent of that invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of the Restrictive Covenants or affecting the validity or enforceability of any of the terms or provisions of the Restrictive Covenants. If any provisions of the Restrictive Covenants are deemed to exceed the time, geographic, or scope limitations permitted by applicable law, then such provisions shall be reformed to the maximum time, geographic, or scope limitations permissible. The Company expressly reserves the right to limit the scope of those covenants unilaterally.

(viii) The Restricted Period shall not expire, and shall be tolled, during any period in which you are in violation of any of the Restrictive Covenants set forth above.

(ix) You acknowledge and agree that (i) any breach or threatened breach of the Restrictive Covenants would cause irreparable harm to the Company, and (ii) monetary damages alone would not be an adequate remedy because they would be difficult or impossible to measure. Therefore, you further acknowledge and agree that in the case of any breach or threatened breach of the Restrictive Covenants, the Company shall be entitled to extraordinary relief, such as a temporary restraining order or injunction, in addition to any other available rights and remedies, including, but not limited to, any forfeiture or recoupment of any Award as described below.

(x) You agree that, if at any time following the date hereof you are found to have breached any Restrictive Covenant, you will pay the Company, in addition to any damages that may be awarded by the court or any forfeiture or recoupment of any Award, reasonable attorneys’ fees incurred by the Company to establish that breach, to obtain injunctive relief, and/or otherwise to enforce the Restrictive Covenants. You acknowledge that the Company shall be entitled to recover from you its reasonable attorneys’ fees if you unsuccessfully challenge the enforceability of the Restricted Covenants.

(xi) You agree that references to the Company in the Restrictive Covenants includes the “Company and its Subsidiaries” and that the scope of the foregoing and referenced agreements is reasonable and necessary in order to protect the interests of the Company and its Subsidiaries, and that the consideration to you with respect to the Restrictive Covenants was sufficient.

You agree and acknowledge that in addition to any injunctive relief to the Company, and notwithstanding anything in the Plan or this Agreement to the contrary, the Company may cause this Award to be forfeited and/or recouped (that is, returned to) the Company if you, during employment or service, or during the Restricted Period, engage in certain specified conduct,

---

including but not limited to breach of (x) any of the Restrictive Covenants set forth above, (y) any non-solicitation, non-competition, confidentiality or other restrictive covenant agreement with the Company or any of its Subsidiaries, or (z) any other conduct by you that is determined by the Company to be detrimental to the business or reputation of the Company or any affiliate. In addition, without limiting the effect of the foregoing, as a condition to the grant of the Award or to the applicable restrictions lapsing or any other benefit under the Award, you agree to abide by any compensation recovery policy and/or other policies adopted by the Company, Subsidiary, or an affiliate, each as in effect from time to time and to the extent applicable to you. Further, you shall be subject to such compensation recovery, recoupment, forfeiture or other similar provisions as may apply under applicable law.

By electronically acknowledging and accepting this Award, you agree that your right to the applicable restrictions on the Award lapsing or any other benefit under the Award, or any portion thereof, is subject to you not having violated the foregoing Restrictive Covenants at any time during the term of the Award, and your acceptance of the applicable restrictions of the Award lapsing shall constitute your certification to the Company that you have not violated and will not violate the Restrictive Covenants at any time during the term of the Award.

Nothing in the Plan or this Agreement shall be interpreted to interfere with or limit in any way the right of the Company or any Subsidiary to terminate your employment or services at any time, nor confer upon you the right to continue in the employ or service of the Company or any Subsidiary.

HUBBELL INCORPORATED

PERFORMANCE SHARE AWARD

HUBBELL INCORPORATED 2005 INCENTIVE AWARD PLAN,

AS AMENDED AND RESTATED

Grant Date: [Grant Date] Performance Period: January 1, 2021 – December 31, 2023

As noted in your Award notification letter, effective on the Grant Date, Hubbell Incorporated (the “Company”) has granted to you an award (the “Award”) of Performance Shares (the “Performance Shares”) in the amount set forth in your Award notification letter, which is your “target.” Each Performance Share represents the right to receive a share of the Company’s Common Stock (the “Common Stock”) subject to the fulfillment of the conditions set forth below. This Award is made pursuant to the terms of the Hubbell Incorporated 2005 Incentive Award Plan, as amended and restated (the “Plan”) and is subject to all of the terms and conditions contained therein. By electronically acknowledging and accepting this Award, you agree to be bound by the terms and conditions herein, the Plan, and any and all conditions established by the Company in connection with Awards issued under the Plan. Defined terms used herein shall have the meaning set forth in the Plan, unless otherwise defined herein.

On any date, one Performance Share has a value equal to the Fair Market Value of one share of Common Stock. Unless and until a Performance Share is earned, you will have no right to any shares of Common Stock. Prior to actual payment, vested Performance Shares represent only an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company.

The number of Performance Shares actually earned, and therefore the number of shares of Common Stock to be delivered will be measured as of the last day of the Performance Period according to Exhibit A hereto; provided, however, that no Performance Shares shall become earned and payable unless and until the Compensation Committee of the Board of Directors of the Company certifies that the performance criteria set forth on Exhibit A hereto have been met. Notwithstanding the foregoing, the target number of Performance Shares will be considered earned and Common Stock equivalent to the target will be payable upon your death or Permanent Disability while employed with or providing services to the Company during the Performance Period. “Permanent Disability” as used in this Agreement means that you are unable to perform your duties by reason of any medically determined physical or mental impairment which can be expected to result in death or which has lasted or is expected to last for a continuous period of at least 12 months such that you are “disabled” within the meaning of Section 1.409A-3(i)(4) of the Treasury regulations, as reasonably determined by the Board of Directors in its discretion. In the case of a Change in Control, the number of Performance Shares actually earned and therefore the number of shares of Common Stock to be delivered will be determined in accordance with Section 10.2 of the Plan.

---

If during the Performance Period you experience a termination of employment or service with the Company (a) other than by reason of death, following your Permanent Disability or by the Company for Cause and (b) on or after age 55 when the sum of your age and service with the Company equals or exceeds 70 (such termination, a “Retirement”) you will be eligible to receive the number of Performance Shares you would have received if you had not retired prior to the end of the Performance Period multiplied by a fraction, the denominator of which is 36 and the numerator of which is the number of months elapsed during the Performance Period to the date of your Retirement. For this purpose “Cause” means (i) misconduct which is reasonably deemed to be prejudicial to the interest of the Company, (ii) utilization or disclosure of confidential information of the Company (or of any other entity learned in the course of your job) for reasons unrelated to your employment or service with the Company, (iii) willful failure to perform the material duties of your job, (iv) fraud in connection with the business affairs of the Company regardless of whether said conduct is designed to defraud the Company or otherwise, (v) violation of the code of conduct or material policies of the Company including, but not limited to, written policies related to discrimination, harassment, performance of illegal or unethical activities, or conflicts of interest, (vi) violation of any fiduciary duty owed to the Company, or (vii) conviction of, plea of no contest or guilty to a felony or other crime involving moral turpitude. Cause shall be determined by the Committee (or such officer of the Company as the Committee may delegate such authority) in its sole and exclusive discretion.

In the event of the termination of your employment or service with the Company and all of its Subsidiaries for any reason other than your death or Retirement or following your Permanent Disability, whether such termination is occasioned by you, by the Company or any of its Subsidiaries, with or without Cause or by mutual agreement prior to the last day of the Performance Period, you will forfeit all rights to the Performance Shares.

Once a Performance Share is considered earned and payable, the Company will cause to be issued the appropriate number of shares of Common Stock payable thereunder. Such shares will be issued in book form, unless you request the shares be issued in certificate form. Shares of Common Stock shall be issued, including in the event of your Retirement, during the calendar year following the calendar year in which the Performance Period ends, generally within the first 120 days of such calendar year, other than in the case of your death or Permanent Disability, in which case the shares of Common shall be issued within thirty (30) days following such event. In the case of a Change in Control, payment of earned and payable Performance Shares will be determined in accordance with Section 10.2 of the Plan.

The Company has the authority to deduct or withhold, or require you to remit to the Company, an amount sufficient to satisfy applicable federal, state, local and foreign taxes (including your FICA obligation) required by law to be withheld with respect to any taxable event arising from this Award. You may satisfy your tax obligation, in whole or in part, by either: (i) electing to have the Company withhold shares of Common Stock otherwise to be delivered with a Fair Market Value equal to the minimum amount of the tax withholding obligation, (ii) surrendering to the Company previously owned shares of Common Stock with a Fair Market Value equal to the minimum amount of the tax withholding obligation, (iii) withholding from other cash compensation, (iv) paying the amount of the tax withholding obligation directly to the Company in cash, or (v) a combination of the foregoing; provided, however, that if the tax obligation arises during a period in which you are prohibited from trading under any policy of the Company or by reason of the Exchange Act, then the tax withholding obligation shall automatically be satisfied

---

by the Company withholding shares of Common Stock otherwise to be delivered with a Fair Market Value equal to the minimum amount of the tax withholding obligation. By electronically acknowledging and accepting this Award, you hereby authorize that Hubbell may automatically satisfy the withholding obligation in any manner it chooses consistent with the preceding sentence.

The Performance Shares or any right or interest therein or part thereof are not transferable except by will or the laws of descent and distribution. Until delivery of the Common Stock upon payment of the Performance Shares, you have no rights or privileges of a stockholder of the Company by reason of this Award. Nothing in the Plan or this Agreement shall be interpreted to interfere with or limit in any way the right of the Company or any Subsidiary to terminate your services at any time, nor confer upon you the right to continue in the service of the Company or any Subsidiary.

This Award of Performance Shares is granted under and governed by the terms and conditions of the Plan. You acknowledge and agree that the Plan has been introduced voluntarily by the Company and in accordance with its terms it may be amended, cancelled, or terminated by the Company, in its sole discretion, at any time. The grant of this Award of Performance Shares under the Plan is a one-time benefit and does not create any contractual or other right to receive awards of performance shares or other benefits in lieu of performance shares in the future. Future awards of performance shares, if any, will be at the sole discretion of the Company, including, but not limited to, the timing of the award, the number of shares and vesting provisions.

You acknowledge and agree to comply with the following covenants (the “Restrictive Covenants”), each of which is individually a material term of this Award and is a condition precedent to the Company making this Award, and is in addition to, and not in lieu of, any other restrictive covenants between you and the Company or any of its affiliates:

(i) You acknowledge that you have and will have possession of or access to apparatus, equipment, drawings, reports, manuals, invention records, customer lists, computer programs, or other material embodying trade secrets or confidential technical or business information of the Company (“Confidential Information”). You agree (a) not to use any such Confidential Information or material for yourself or others, and (b) not to take any such Confidential Information or reproductions of all or any portion thereof from Company facilities, in any case at any time during or after your employment by or service to the Company, except as required in your duties to the Company. You agree immediately to return all such Confidential Information and reproductions thereof in your possession to the Company upon request and in any event, upon termination of employment or service. Except with prior written authorization by the Company, you further agree not to disclose or publish any trade secret or Confidential Information of the Company or of another party to whom the Company owes an obligation of confidence, at any time during or after your employment by or service to the Company.

(ii) You agree that while providing services to the Company, you had and/or will have contact with and become aware of some, most or all of the customers of the Company, representatives of those customers, their names and addresses, specific customer and supplier needs and requirements, and leads and references to prospective customers. You agree that during the period of your employment or service with the Company and for the period beginning on the date of your termination of employment or

---

service with the Company for any reason (the “Date of Termination”) and ending on the twelve-month anniversary thereof (such period, the “Restricted Period”), you will not directly or indirectly (a) solicit any person or entity to whom the Company has provided products or services, or any person or entity whom the Company is actively soliciting to provide products or services as of the Date of Termination, for the purpose of providing any product or service that is competitive with any product or service then offered by the Company or (b) accept business from any person or entity to whom the Company has provided products or services in the two (2) years immediately prior to the Date of Termination, where such acceptance of business concerns any product or service that is competitive with any product or service then offered by the Company. The restrictions set forth in this paragraph shall only apply to any person or entity with whom you had contact or about whom you received confidential information during the two (2) years immediately prior to the Date of Termination. For purposes of this paragraph, “contact” means interaction between you and the person or entity which takes place to further the business relationship with the Company, or performing services for the person or entity on behalf of the Company.

(iii) You agree that during the Restricted Period, you will not directly or indirectly solicit, recruit, hire or attempt to recruit or hire any other employee of the Company with whom you had contact during your employment or service with the Company. For purposes of this paragraph, “contact” means any interaction whatsoever between you and the other employee related to the Company.

(iv) You agree to the following restrictions: (a) during the Restricted Period, you will not, within the defined “geographic region,” directly or indirectly own, manage, operate, join or control or participate in the ownership management, operation or control of, or become a director or employee of, or a consultant to, any person, firm, or entity selling or distributing products that are competitive with the products you worked on during the two years immediately prior to the Date of Termination (each, a “Competitor”). For the purposes of this paragraph, if you were assigned a geographic territory while employed by or providing services to the Company, the term “geographic region” shall mean the countries, states, provinces, and/or cities within any geographic territory assigned to you within the two years immediately prior to the Date of Termination. For the purposes of this paragraph, if you were not assigned a geographic territory (such as for engineers or management personnel) the term “geographic region” shall mean (i) any countries, states, provinces, and/or cities where the Company sold or distributed the products you worked on or for which you were responsible during the two years immediately prior to the Date of Termination, or, if a court deems this geographic region overly broad, then (ii) the United States, or if a court deems this geographic region overly broad, then (iii) the state state(s) in which you regularly worked during the two years immediately prior to the Date of Termination.

(v) In the event you believe your activity in violation of these Restrictive Covenants would not harm the Company’s legitimate business interests, you may request that the Company waive the restrictions contained in this paragraph. Any such request shall be made in writing to the Company, c/o Hubbell Incorporated, 40 Waterview Drive, Shelton, CT 06484-1000, Attention: General Counsel, and shall identify the business with whom/which you seek to associate and describe the duties that you seek to perform. The Company has the sole discretion whether to grant such a waiver and no waiver of any restrictions under this provision shall be effective unless in writing and signed by an authorized representative of the Company.

---

(vi) You agree that the time, geographic, and scope limitations of the Restrictive Covenants are reasonable and necessary to protect the Company’s confidential information, trade secrets, and goodwill.

(vii) The terms of the Restrictive Covenants are severable. Any term or provision of the Restrictive Covenants that is held to be invalid or unenforceable shall be ineffective to the extent of that invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of the Restrictive Covenants or affecting the validity or enforceability of any of the terms or provisions of the Restrictive Covenants. If any provisions of the Restrictive Covenants are deemed to exceed the time, geographic, or scope limitations permitted by applicable law, then such provisions shall be reformed to the maximum time, geographic, or scope limitations permissible. The Company expressly reserves the right to limit the scope of those covenants unilaterally.

(viii) The Restricted Period shall not expire, and shall be tolled, during any period in which you are in violation of any of the Restrictive Covenants set forth above.

(ix) You acknowledge and agree that (i) any breach or threatened breach of the Restrictive Covenants would cause irreparable harm to the Company, and (ii) monetary damages alone would not be an adequate remedy because they would be difficult or impossible to measure. Therefore, you further acknowledge and agree that in the case of any breach or threatened breach of the Restrictive Covenants, the Company shall be entitled to extraordinary relief, such as a temporary restraining order or injunction, in addition to any other available rights and remedies, including, but not limited to, any forfeiture or recoupment of any Award as described below.

(x) You agree that, if at any time following the date hereof you are found to have breached any Restrictive Covenant, you will pay the Company, in addition to any damages that may be awarded by the court or any forfeiture or recoupment of any Award, reasonable attorneys’ fees incurred by the Company to establish that breach, to obtain injunctive relief, and/or otherwise to enforce the Restrictive Covenants. You acknowledge that the Company shall be entitled to recover from you its reasonable attorneys’ fees if you unsuccessfully challenge the enforceability of the Restricted Covenants.

(xi) You agree that references to the Company in the Restrictive Covenants includes the “Company and its Subsidiaries” and that the scope of the foregoing and referenced agreements is reasonable and necessary in order to protect the interests of the Company and its Subsidiaries, and that the consideration to you with respect to the Restrictive Covenants was sufficient.

You agree and acknowledge that in addition to any injunctive relief to the Company, and notwithstanding anything in the Plan or this Agreement to the contrary, the Company may cause this Award to be forfeited and/or recouped (that is, returned to) the Company if you, during employment or service, or during the Restricted Period, engage in certain specified conduct, including but not limited to breach of (x) any of the Restrictive Covenants set forth above, (y) any non-solicitation, non-competition, confidentiality or other restrictive covenant agreement with the Company or any of its Subsidiaries, or (z) any other conduct by you that is determined by the Company to be detrimental to the business or reputation of the Company or any affiliate. In addition, without limiting the effect of the foregoing, as a condition to the grant of the Award or to the applicable restrictions lapsing or any other benefit under the Award, you agree to abide by any compensation recovery policy and/or other policies adopted by the Company, Subsidiary, or an affiliate, each as in effect from time to time and to the extent applicable to you. Further,

---

you shall be subject to such compensation recovery, recoupment, forfeiture or other similar provisions as may apply under applicable law.

By electronically acknowledging and accepting this Award, you agree that your right to the applicable restrictions on the Award lapsing or any other benefit under the Award, or any portion thereof, is subject to you not having violated the foregoing Restrictive Covenants at any time during the term of the Award, and your acceptance of the applicable restrictions of the Award lapsing shall constitute your certification to the Company that you have not violated and will not violate the Restrictive Covenants at any time during the term of the Award.

Nothing in the Plan or this Agreement shall be interpreted to interfere with or limit in any way the right of the Company or any Subsidiary to terminate your employment or services at any time, nor confer upon you the right to continue in the employ or service of the Company or any Subsidiary.

This Award is granted under and governed by the terms and conditions of the Plan. You acknowledge and agree that the Plan has been introduced voluntarily by the Company and in accordance with its terms it may be amended, cancelled, or terminated by the Company, in its sole discretion, at any time. This Award under the Plan is a one-time benefit and does not create any contractual or other right to receive a Performance Share Award or benefits in lieu of such Award in the future. Future awards, if any, will be at the sole discretion of the Company, including, but not limited to, the timing of the award, the number of shares and vesting provisions.

This Award shall be governed by Connecticut law without regard to choice of law principles.

HUBBELL INCORPORATED

PERFORMANCE SHARE AWARD

HUBBELL INCORPORATED 2005 INCENTIVE AWARD PLAN,

AS AMENDED AND RESTATED

Grant Date: [Grant Date] Performance Period: January 1, 2022 – December 31, 2024

As noted in your Award notification letter, effective on the Grant Date, Hubbell Incorporated (the “Company”) has granted to you an award (the “Award”) of Performance Shares (the “Performance Shares”) in the amount set forth in your Award notification letter, which is your “target.” Each Performance Share represents the right to receive a share of the Company’s Common Stock (the “Common Stock”) subject to the fulfillment of the conditions set forth below. This Award is made pursuant to the terms of the Hubbell Incorporated 2005 Incentive Award Plan, as amended and restated (the “Plan”) and is subject to all of the terms and conditions contained therein. By electronically acknowledging and accepting this Award, you agree to be bound by the terms and conditions herein, the Plan, and any and all conditions established by the Company in connection with Awards issued under the Plan. Defined terms used herein shall have the meaning set forth in the Plan, unless otherwise defined herein.

On any date, one Performance Share has a value equal to the Fair Market Value of one share of Common Stock. Unless and until a Performance Share is earned, you will have no right to any shares of Common Stock. Prior to actual payment, vested Performance Shares represent only an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company.

The number of Performance Shares actually earned, and therefore the number of shares of Common Stock to be delivered will be measured as of the last day of the Performance Period according to Exhibit A hereto; provided, however, that no Performance Shares shall become earned and payable unless and until the Compensation Committee of the Board of Directors of the Company certifies that the performance criteria set forth on Exhibit A hereto have been met. Notwithstanding the foregoing, the target number of Performance Shares will be considered earned and Common Stock equivalent to the target will be payable upon your death or Permanent Disability while employed with or providing services to the Company during the Performance Period. “Permanent Disability” as used in this Agreement means that you are unable to perform your duties by reason of any medically determined physical or mental impairment which can be expected to result in death or which has lasted or is expected to last for a continuous period of at least 12 months such that you are “disabled” within the meaning of Section 1.409A-3(i)(4) of the Treasury regulations, as reasonably determined by the Board of Directors in its discretion. In the case of a Change in Control, the number of Performance Shares actually earned and therefore the number of shares of Common Stock to be delivered will be determined in accordance with Section 10.2 of the Plan.

If during the Performance Period you experience a termination of employment or service with the Company (a) other than by reason of death, following your Permanent Disability or by the

---

Company for Cause and (b) on or after age 55 when the sum of your age and service with the Company equals or exceeds 70 (such termination, a “Retirement”) you will be eligible to receive the number of Performance Shares you would have received if you had not retired prior to the end of the Performance Period multiplied by a fraction, the denominator of which is 36 and the numerator of which is the number of months elapsed during the Performance Period to the date of your Retirement. For this purpose “Cause” means (i) misconduct which is reasonably deemed to be prejudicial to the interest of the Company, (ii) utilization or disclosure of confidential information of the Company (or of any other entity learned in the course of your job) for reasons unrelated to your employment or service with the Company, (iii) willful failure to perform the material duties of your job, (iv) fraud in connection with the business affairs of the Company regardless of whether said conduct is designed to defraud the Company or otherwise, (v) violation of the code of conduct or material policies of the Company including, but not limited to, written policies related to discrimination, harassment, performance of illegal or unethical activities, or conflicts of interest, (vi) violation of any fiduciary duty owed to the Company, or (vii) conviction of, plea of no contest or guilty to a felony or other crime involving moral turpitude. Cause shall be determined by the Committee (or such officer of the Company as the Committee may delegate such authority) in its sole and exclusive discretion.

In the event of the termination of your employment or service with the Company and all of its Subsidiaries for any reason other than your death or Retirement or following your Permanent Disability, whether such termination is occasioned by you, by the Company or any of its Subsidiaries, with or without Cause or by mutual agreement prior to the last day of the Performance Period, you will forfeit all rights to the Performance Shares.

Once a Performance Share is considered earned and payable, the Company will cause to be issued the appropriate number of shares of Common Stock payable thereunder. Such shares will be issued in book form, unless you request the shares be issued in certificate form. Shares of Common Stock shall be issued, including in the event of your Retirement, during the calendar year following the calendar year in which the Performance Period ends, generally within the first 120 days of such calendar year, other than in the case of your death or Permanent Disability, in which case the shares of Common shall be issued within thirty (30) days following such event. In the case of a Change in Control, payment of earned and payable Performance Shares will be determined in accordance with Section 10.2 of the Plan.

The Company has the authority to deduct or withhold, or require you to remit to the Company, an amount sufficient to satisfy applicable federal, state, local and foreign taxes (including your FICA obligation) required by law to be withheld with respect to any taxable event arising from this Award. You may satisfy your tax obligation, in whole or in part, by either: (i) electing to have the Company withhold shares of Common Stock otherwise to be delivered with a Fair Market Value equal to the minimum amount of the tax withholding obligation, (ii) surrendering to the Company previously owned shares of Common Stock with a Fair Market Value equal to the minimum amount of the tax withholding obligation, (iii) withholding from other cash compensation, (iv) paying the amount of the tax withholding obligation directly to the Company in cash, or (v) a combination of the foregoing; provided, however, that if the tax obligation arises during a period in which you are prohibited from trading under any policy of the Company or by reason of the Exchange Act, then the tax withholding obligation shall automatically be satisfied by the Company withholding shares of Common Stock otherwise to be delivered with a Fair Market Value equal to the minimum amount of the tax withholding obligation. By electronically acknowledging and accepting this Award, you hereby authorize that Hubbell may automatically satisfy the withholding obligation in any manner it chooses consistent with the preceding sentence.

---

The Performance Shares or any right or interest therein or part thereof are not transferable except by will or the laws of descent and distribution. Until delivery of the Common Stock upon payment of the Performance Shares, you have no rights or privileges of a stockholder of the Company by reason of this Award. Nothing in the Plan or this Agreement shall be interpreted to interfere with or limit in any way the right of the Company or any Subsidiary to terminate your services at any time, nor confer upon you the right to continue in the service of the Company or any Subsidiary.

This Award of Performance Shares is granted under and governed by the terms and conditions of the Plan. You acknowledge and agree that the Plan has been introduced voluntarily by the Company and in accordance with its terms it may be amended, cancelled, or terminated by the Company, in its sole discretion, at any time. The grant of this Award of Performance Shares under the Plan is a one-time benefit and does not create any contractual or other right to receive awards of performance shares or other benefits in lieu of performance shares in the future. Future awards of performance shares, if any, will be at the sole discretion of the Company, including, but not limited to, the timing of the award, the number of shares and vesting provisions.

You acknowledge and agree to comply with the following covenants (the “Restrictive Covenants”), each of which is individually a material term of this Award and is a condition precedent to the Company making this Award, and is in addition to, and not in lieu of, any other restrictive covenants between you and the Company or any of its affiliates:

(i) You acknowledge that you have and will have possession of or access to apparatus, equipment, drawings, reports, manuals, invention records, customer lists, computer programs, or other material embodying trade secrets or confidential technical or business information of the Company (“Confidential Information”).

You agree immediately to return all such Confidential Information and reproductions thereof in your possession to the Company upon request and in any event, upon termination of employment or service. Except with prior written authorization by the Company, you further agree not to disclose or publish any trade secret or Confidential Information of the Company or of another party to whom the Company owes an obligation of confidence, at any time during or after your employment by or service to the Company.

(ii) You agree that while providing services to the Company, you had and/or will have contact with and become aware of some, most or all of the customers of the Company, representatives of those customers, their names and addresses, specific customer and supplier needs and requirements, and leads and references to prospective customers. You agree that during the period of your employment or service with the Company and for the period beginning on the date of your termination of employment or service with the Company for any reason (the “Date of Termination”) and ending on the twelve-month anniversary thereof (such period, the “Restricted Period”), you will not directly or indirectly (a) solicit any person or entity to whom the Company has provided products or services, or any person or entity whom the Company is actively soliciting to provide products or services as of the Date of Termination, for the purpose of providing any product or service that is competitive with any product or service then offered by the Company or (b) accept business from any person or entity to whom the Company has provided products or services in the two (2) years immediately prior to the Date of

---

Termination, where such acceptance of business concerns any product or service that is competitive with any product or service then offered by the Company. The restrictions set forth in this paragraph shall only apply to any person or entity with whom you had contact or about whom you received confidential information during the two (2) years immediately prior to the Date of Termination. For purposes of this paragraph, “contact” means interaction between you and the person or entity which takes place to further the business relationship with the Company, or performing services for the person or entity on behalf of the Company.

(iii) You agree that during the Restricted Period, you will not directly or indirectly solicit, recruit, hire or attempt to recruit or hire any other employee of the Company with whom you had contact during your employment or service with the Company. For purposes of this paragraph, “contact” means any interaction whatsoever between you and the other employee related to the Company.

(iv) You agree to the following restrictions: (a) during the Restricted Period, you will not, within the defined “geographic region,” directly or indirectly own, manage, operate, join or control or participate in the ownership management, operation or control of, or become a director or employee of, or a consultant to, any person, firm, or entity selling or distributing products that are competitive with the products you worked on during the two years immediately prior to the Date of Termination (each, a “Competitor”). For the purposes of this paragraph, if you were assigned a geographic territory while employed by or providing services to the Company, the term “geographic region” shall mean the countries, states, provinces, and/or cities within any geographic territory assigned to you within the two years immediately prior to the Date of Termination. For the purposes of this paragraph, if you were not assigned a geographic territory (such as for engineers or management personnel) the term “geographic region” shall mean (i) any countries, states, provinces, and/or cities where the Company sold or distributed the products you worked on or for which you were responsible during the two years immediately prior to the Date of Termination, or, if a court deems this geographic region overly broad, then (ii) the United States, or if a court deems this geographic region overly broad, then (iii) the state state(s) in which you regularly worked during the two years immediately prior to the Date of Termination.

(ix) You acknowledge and agree that (i) any breach or threatened breach of the Restrictive Covenants would cause irreparable harm to the Company, and (ii) monetary damages alone would not be an adequate remedy because they would be difficult or impossible to measure. Therefore, you further acknowledge and agree that in the case of any breach or threatened breach of the Restrictive Covenants, the Company shall be entitled to extraordinary relief, such as a temporary restraining order or injunction, in addition to any other available rights and remedies, including, but not limited to, any forfeiture or recoupment of any Award as described below.

(x) You agree that, if at any time following the date hereof you are found to have breached any Restrictive Covenant, you will pay the Company, in addition to any damages that may be awarded by the court or any forfeiture or recoupment of any Award, reasonable attorneys’ fees incurred by the Company to establish that breach, to obtain injunctive relief, and/or otherwise to enforce the Restrictive Covenants. You acknowledge that the Company shall be entitled to recover from you its reasonable attorneys’ fees if you unsuccessfully challenge the enforceability of the Restricted Covenants.

(xi) You agree that references to the Company in the Restrictive Covenants includes the “Company and its Subsidiaries” and that the scope of the foregoing and referenced agreements is reasonable and necessary in order to protect the interests of the Company and its Subsidiaries, and that the consideration to you with respect to the Restrictive Covenants was sufficient.

You agree and acknowledge that in addition to any injunctive relief to the Company, and notwithstanding anything in the Plan or this Agreement to the contrary, the Company may cause this Award to be forfeited and/or recouped (that is, returned to) the Company if you, during employment or service, or during the Restricted Period, engage in certain specified conduct, including but not limited to breach of (x) any of the Restrictive Covenants set forth above, (y) any non-solicitation, non-competition, confidentiality or other restrictive covenant agreement with the Company or any of its Subsidiaries, or (z) any other conduct by you that is determined by the Company to be detrimental to the business or reputation of the Company or any affiliate. In addition, without limiting the effect of the foregoing, as a condition to the grant of the Award or to the applicable restrictions lapsing or any other benefit under the Award, you agree to abide by any compensation recovery policy and/or other policies adopted by the Company, Subsidiary, or an affiliate, each as in effect from time to time and to the extent applicable to you. Further, you shall be subject to such compensation recovery, recoupment, forfeiture or other similar provisions as may apply under applicable law.

By electronically acknowledging and accepting this Award, you agree that your right to the applicable restrictions on the Award lapsing or any other benefit under the Award, or any portion thereof, is subject to you not having violated the foregoing Restrictive Covenants at any time during the term of the Award, and your acceptance of the applicable restrictions of the Award lapsing shall constitute your certification to the Company that you have not violated and will not violate the Restrictive Covenants at any time during the term of the Award.

(i) You acknowledge that you have and will have possession of or access to apparatus, equipment, drawings, reports, manuals, invention records, customer lists, computer programs, or other material embodying trade secrets or confidential technical or business information of the Company (“Confidential Information”). You agree (a) not to use any such Confidential Information or material for yourself or others, and (b) not to take any such Confidential Information or reproductions of all or any portion thereof from Company facilities, in any case at any time during or after your employment by or service to the Company, except as required in your duties to the Company.

Any such request shall be made in writing to the Company, c/o Hubbell Incorporated, 40 Waterview Drive, Shelton, CT 06484-1000, Attention: General Counsel, and shall identify the business with whom/which you seek to associate and describe the duties that you seek to perform.

By electronically acknowledging and accepting this Award, you agree that your right to the applicable restrictions on the Award lapsing or any other benefit under the Award, or any portion thereof, is subject to you not having violated the foregoing Restrictive Covenants at any time during the term of the Award, and your acceptance of the applicable restrictions of the Award lapsing shall constitute your certification to the Company that you have not violated and will not violate the Restrictive Covenants at any time during the term of the Award.

You may satisfy your tax obligation, in whole or in part, by either: (i) electing to have the number of shares of your Restricted Stock that are vesting with a Fair Market Value equal to the minimum amount of the tax withholding obligation (the “Tax Withholding Shares”) returned to the Company, (ii) surrendering to the Company previously owned shares with a Fair Market Value equal to the minimum amount of the tax withholding obligation, (iii) withholding from other cash compensation, (iv) paying the amount of the tax withholding obligation directly to the Company in cash, or (v) a combination of the foregoing; provided, however, that if the tax obligation arises during a period in which you are either an officer of the Company subject to Section 16(a) of the Exchange Act or prohibited from trading under any policy of the Company or by reason of the Exchange Act, then the tax withholding obligation shall automatically be satisfied by the Tax Withholding Shares being returned to the Company (i.e., by the number of shares of unrestricted stock previously issued to you as Restricted Stock in certificated or book entry form being reduced by the Tax Withholding Shares). By electronically acknowledging and accepting this Award, you hereby authorize that Hubbell may automatically satisfy the withholding obligation in any manner it chooses consistent with the preceding sentence.

Nothing in the Plan or this Agreement shall be interpreted to interfere with or limit in any way the right of the Company or any Subsidiary to terminate your employment or services at any time, nor confer upon you the right to continue in the employ or service of the Company or any Subsidiary.

This Award of Restricted Stock is granted under and governed by the terms and conditions of the Plan. You acknowledge and agree that the Plan has been introduced voluntarily by the Company and in accordance with its terms it may be amended, cancelled, or terminated by the Company, in its sole discretion, at any time.

---

Restricted Stock in the future. Future awards of Restricted Stock, if any, will be at the sole discretion of the Company, including, but not limited to, the timing of the award, the number of shares and vesting provisions.

This Award of Restricted Stock shall be governed by Connecticut law without regard to choice of law principles.

You acknowledge that the Company shall be entitled to recover from you its reasonable attorneys’ fees if you unsuccessfully challenge the enforceability of the Restricted Covenants.

(xi) You agree that references to the Company in the Restrictive Covenants includes the “Company and its Subsidiaries” and that the scope of the foregoing and referenced agreements is reasonable and necessary in order to protect the interests of the Company and its Subsidiaries, and that the consideration to you with respect to the Restrictive Covenants was sufficient.

You agree and acknowledge that in addition to any injunctive relief to the Company, and notwithstanding anything in the Plan or this Agreement to the contrary, the Company may cause this Award to be forfeited and/or recouped (that is, returned to) the Company if you, during employment or service, or during the Restricted Period, engage in certain specified conduct, including but not limited to breach of (x) any of the Restrictive Covenants set forth above, (y) any non-solicitation, non-competition, confidentiality or other restrictive covenant agreement with the Company or any of its Subsidiaries, or (z) any other conduct by you that is determined by the Company to be detrimental to the business or reputation of the Company or any affiliate. In addition, without limiting the effect of the foregoing, as a condition to the grant of the Award of Restricted Stock or to the applicable restrictions lapsing or any other benefit under the Award, you agree to abide by any compensation recovery policy and/or other policies adopted by the Company, Subsidiary, or an affiliate, each as in effect from time to time and to the extent applicable to you. Further, you shall be subject to such compensation recovery, recoupment, forfeiture or other similar provisions as may apply under applicable law.

---

By electronically acknowledging and accepting this Award, you agree that your right to the applicable restrictions on the Award lapsing or any other benefit under the Award, or any portion thereof, is subject to you not having violated the foregoing Restrictive Covenants at any time during the term of the Award, and your acceptance of the applicable restrictions of the Award lapsing shall constitute your certification to the Company that you have not violated and will not violate the Restrictive Covenants at any time during the term of the Award. The Company has the authority to deduct or withhold, or require you to remit to the Company, an amount sufficient to satisfy applicable federal, state, local and foreign taxes (including your FICA obligation) required by law to be withheld with respect to any taxable event arising from this Restricted Stock Award. You may satisfy your tax obligation, in whole or in part, by either: (i) electing to have the number of shares of your Restricted Stock that are vesting with a Fair Market Value equal to the minimum amount of the tax withholding obligation (the “Tax Withholding Shares”) returned to the Company, (ii) surrendering to the Company previously owned shares with a Fair Market Value equal to the minimum amount of the tax withholding obligation, (iii) withholding from other cash compensation, (iv) paying the amount of the tax withholding obligation directly to the Company in cash, or (v) a combination of the foregoing; provided, however, that if the tax obligation arises during a period in which you are either an officer of the Company subject to Section 16(a) of the Exchange Act or prohibited from trading under any policy of the Company or by reason of the Exchange Act, then the tax withholding obligation shall automatically be satisfied by the Tax Withholding Shares being returned to the Company (i.e., by the number of shares of unrestricted stock previously issued to you as Restricted Stock in certificated or book entry form being reduced by the Tax Withholding Shares). By electronically acknowledging and accepting this Award, you hereby authorize that Hubbell may automatically satisfy the withholding obligation in any manner it chooses consistent with the preceding sentence.

Nothing in the Plan or this Agreement shall be interpreted to interfere with or limit in any way the right of the Company or any Subsidiary to terminate your employment or services at any time, nor confer upon you the right to continue in the employ or service of the Company or any Subsidiary.

This Award of Restricted Stock is granted under and governed by the terms and conditions of the Plan. You acknowledge and agree that the Plan has been introduced voluntarily by the Company and in accordance with its terms it may be amended, cancelled, or terminated by the Company, in its sole discretion, at any time. This Award of Restricted Stock under the Plan is a one-time benefit and does not create any contractual or other right to receive an award of Restricted Stock or benefits in lieu of Restricted Stock in the future. Future awards of Restricted Stock, if any, will be at the sole discretion of the Company, including, but not limited to, the timing of the award, the number of shares and vesting provisions.

This Award of Restricted Stock shall be governed by Connecticut law without regard to choice of law principles.

HUBBELL INCORPORATED

STOCK APPRECIATION RIGHTS AGREEMENT

HUBBELL INCORPORATED 2005 INCENTIVE AWARD PLAN,

AS AMENDED AND RESTATED

Base Price: [FMV of Common Stock on Grant Date] Grant Date: [Grant Date]

As noted in your Award notification letter, effective on the Grant Date you have been granted the number of Stock Appreciation Rights (the “Rights”) set forth in the Award notification letter. Each Right entitles you to the positive difference, if any, between the “Base Price” designated in the Award notification letter and the Fair Market Value of a share of Common Stock, par value $0.01 per share (the “Common Stock”) of Hubbell Incorporated (the “Company”) on the date of exercise (the “Spread”), in accordance with the provisions of the Award notification letter, this Agreement setting forth terms and conditions to the Award, and the Hubbell Incorporated 2005 Incentive Award Plan, as amended and restated (the “Plan”). By electronically acknowledging and accepting this Award, you agree to be bound by the terms and conditions herein, the Plan, and any and all conditions established by the Company in connection with Awards issued under the Plan. Defined terms used herein shall have the meaning set forth in the Plan, unless otherwise defined herein.

Upon exercise of the Rights, the Spread will be paid in whole shares of Common Stock with a Fair Market Value equal to the Spread. You may only exercise a Right once it is vested, and will forfeit all unvested Rights in the event of the termination of your employment or service with the Company and all of its Subsidiaries for any reason other than Retirement, whether such termination is occasioned by you, by the Company or any of its Subsidiaries, with or without cause or by mutual agreement (“Termination of Service”).

The Rights will vest and may be exercised in one-third increments on each anniversary of the Grant Date. Notwithstanding the foregoing, the Rights shall be fully vested and exercisable upon your Termination of Service by reason of death or Permanent Disability. Upon a Change in Control, the Rights will vest and may be exercised in accordance with Section 10.2 of the Plan. The Rights shall continue to vest and be exercisable on each anniversary of the Grant Date following your Termination of Service by reason of Retirement; provided that in the event of your death within 90 days following your Termination of Service by reason of Retirement, the outstanding Rights shall be fully vested upon your death.

Once vested, Rights may be exercised in whole or any part, at any time. However, vested Rights must be exercised, if at all, prior to the earlier of:

(a) one year following Termination of Service by reason of death;

(b) 90 days following Termination of Service for any reason other than death or Retirement; provided however if Termination of Service is by reason of Retirement or by reason of Permanent Disability and you die within 90 days following such Termination of Service, then the vested Rights may be exercised until one year following your Termination of Service;

(c) Termination of Service for Cause;

(d) violation of any Restrictive Covenants; and

---

(e) the tenth anniversary of the Grant Date (including in the event of Termination of Service by reason of Retirement);

and if not exercised prior thereto, the Rights shall terminate and no longer be exercisable.

“Permanent Disability” means that you are unable to perform your duties by reason of any medically determined physical or mental impairment which can be expected to result in death or which has lasted or is expected to last for a continuous period of at least 12 months, as reasonably determined by the Board of Directors in its discretion. Additionally, “Retirement” means your Termination of Service other than by reason of termination for death, Permanent Disability or Cause on or after age 55 when the sum of your age and service with the Company equals or exceeds 70. “Cause” means (i) misconduct which is reasonably deemed to be prejudicial to the interest of the Company, (ii) utilization or disclosure of confidential information of the Company (or of any other entity learned in the course of your job) for reasons unrelated to your employment with the Company, (iii) willful failure to perform the material duties of your job, (iv) fraud in connection with the business affairs of the Company regardless of whether said conduct is designed to defraud the Company or otherwise, (v) violation of the code of conduct or material policies of the Company including, but not limited to, written policies related to discrimination, harassment, performance of illegal or unethical activities, or conflicts of interest, (vi) violation of any fiduciary duty owed to the Company, or (vii) conviction of, plea of no contest or guilty to a felony or other crime involving moral turpitude. Cause shall be determined by the Committee (or such officer of the Company as the Committee may delegate such authority) in its sole and exclusive discretion.

Notwithstanding anything contained herein to the contrary, the Rights will terminate and no longer be exercisable in the event that you are in Competition with the Company (the “Restrictive Covenant”). For this purpose, “Competition” shall mean that you, directly or indirectly, anywhere in the United States or outside of the United States in a jurisdiction in which the Company operates or otherwise sells its products in a competitive market, own, manage, operate, join or control, or participate in the ownership, management, operation or control of, or become a director or an employee of, or a consultant to, any person, firm or corporation which competes with the products and services of the Company; provided, however, that you shall not be in Competition with the Company as a result of investments in shares of stock traded on a national securities exchange or on the national over-the-counter market with an aggregate market value, at the time of acquisition, of less than two percent (2%) of the outstanding shares of such stock. By electronically acknowledging and accepting this Award, you agree that your right to exercise the Award, or any portion thereof, is subject to you not having been in Competition with the Company at any time during the term of the Award, and your exercise of the Award, or any portion thereof, shall constitute your certification to the Company that you have not been in Competition with the Company at any time during the term of the Award.

By electronically acknowledging and accepting this Award, you agree that your right to exercise the Award, or any portion thereof, is subject to you not having violated the foregoing Restrictive Covenant at any time during the term of the Award, and your exercise of the Award, or any portion thereof, shall constitute your certification to the Company that you have not violated and will not violate the Restrictive Covenant at any time during the term of the Award.

The Rights may be exercised pursuant to such procedures as the Company may establish and communicate to you from time to time. The Spread shall be determined by reference to the Fair

    

---

Market Value of Common Stock on the date all required steps to exercise the Rights as established by the Company have been completed by you. Rights are not transferable except by will or the laws of descent and distribution.

The Company has the authority to deduct or withhold, or require you to remit to the Company, an amount sufficient to satisfy applicable federal, state, local and foreign taxes (including your FICA obligation) required by law to be withheld with respect to any taxable event arising from the exercise of any vested Rights. You may satisfy your tax obligation, in whole or in part, by either: (i) electing to have the Company withhold shares of Common Stock otherwise to be delivered with a Fair Market Value equal to the minimum amount of the tax withholding obligation, (ii) surrendering to the Company previously owned shares with a Fair Market Value equal to the minimum amount of the tax withholding obligation, (iii) withholding from other cash compensation,(iv) paying the amount of the tax withholding obligation directly to the Company in cash or (v) a combination of the foregoing; provided, however, that if the tax obligation arises during a period in which you are prohibited from trading under any policy of the Company or by reason of the Exchange Act, then the tax withholding obligation shall automatically be satisfied by the Company withholding shares of Common Stock otherwise to be delivered with a Fair Market Value equal to the minimum amount of the tax withholding obligation. By electronically acknowledging and accepting this Award, you hereby authorize that Hubbell may automatically satisfy the withholding obligation in any manner it chooses consistent with the preceding sentence.

Nothing in the Plan or this Agreement shall be interpreted to interfere with or limit in any way the right of the Company or any Subsidiary to terminate your employment or services at any time, nor confer upon you the right to continue in the employ or service of the Company or any Subsidiary.

The Rights are granted under and governed by the terms and conditions of the Plan. You acknowledge and agree that the Plan has been introduced voluntarily by the Company and in accordance with its terms it may be amended, cancelled, or terminated by the Company, in its sole discretion, at any time. The grant of the Rights is a one-time benefit and does not create any contractual or other right to receive additional Stock Appreciation Rights or other benefits in lieu of stock appreciation rights in the future. Future awards of Stock Appreciation Rights, if any, will be at the sole discretion of the Company, including, but not limited to, the timing of the award, the number of shares subject to such award and vesting provisions.

You acknowledge and agree to comply with the following covenants (the “Restrictive Covenants”), each of which is individually a material term of this Award and is a condition precedent to the Company making this Award, and is in addition to, and not in lieu of, any other restrictive covenants between you and the Company or any of its affiliates:

(i) You acknowledge that you have and will have possession of or access to apparatus, equipment, drawings, reports, manuals, invention records, customer lists, computer programs, or other material embodying trade secrets or confidential technical or business information of the Company (“Confidential Information”). You agree (a) not to use any such Confidential Information or material for yourself or others, and (b) not to take any such Confidential Information or reproductions of all or any portion thereof from Company facilities, in any case at any time during or after your employment by or service to the Company, except as required in your duties to the Company. You agree immediately to return all such Confidential Information and reproductions thereof in your

    

---

possession to the Company upon request and in any event, upon Termination of Service. Except with prior written authorization by the Company, you further agree not to disclose or publish any trade secret or Confidential Information of the Company or of another party to whom the Company owes an obligation of confidence, at any time during or after your employment by or service to the Company.

(ii) You agree that while providing services to the Company, you had and/or will have contact with and become aware of some, most or all of the customers of the Company, representatives of those customers, their names and addresses, specific customer and supplier needs and requirements, and leads and references to prospective customers. You agree that during the period of your employment or service with the Company and for the period beginning on the date of your Termination of Service (the “Date of Termination”) and ending on the twelve-month anniversary thereof (such period, the “Restricted Period”), you will not directly or indirectly (a) solicit any person or entity to whom the Company has provided products or services, or any person or entity whom the Company is actively soliciting to provide products or services as of the Date of Termination, for the purpose of providing any product or service that is competitive with any product or service then offered by the Company or (b) accept business from any person or entity to whom the Company has provided products or services in the two (2) years immediately prior to the Date of Termination, where such acceptance of business concerns any product or service that is competitive with any product or service then offered by the Company. The restrictions set forth in this paragraph shall only apply to any person or entity with whom you had contact or about whom you received confidential information during the two (2) years immediately prior to the Date of Termination. For purposes of this paragraph, “contact” means interaction between you and the person or entity which takes place to further the business relationship with the Company, or performing services for the person or entity on behalf of the Company.

(iii) You agree that during the Restricted Period, you will not directly or indirectly solicit, recruit, hire or attempt to recruit or hire any other employee of the Company with whom you had contact during your employment or service with the Company. For purposes of this paragraph, “contact” means any interaction whatsoever between you and the other employee related to the Company.

(iv) You agree to the following restrictions: (a) during the Restricted Period, you will not, within the defined “geographic region,” directly or indirectly own, manage, operate, join or control or participate in the ownership management, operation or control of, or become a director or employee of, or a consultant to, any person, firm, or entity selling or distributing products that are competitive with the products you worked on during the two years immediately prior to the Date of Termination (each, a “Competitor”). For the purposes of this paragraph, if you were assigned a geographic territory while employed by or providing services to the Company, the term “geographic region” shall mean the countries, states, provinces, and/or cities within any geographic territory assigned to you within the two years immediately prior to the Date of Termination. For the purposes of this paragraph, if you were not assigned a geographic territory (such as for engineers or management personnel) the term “geographic region” shall mean (i) any countries, states, provinces, and/or cities where the Company sold or distributed the products you worked on or for which you were responsible during the two years immediately prior to the Date of Termination, or, if a court deems this geographic region overly broad, then (ii) the United States, or if a court deems this geographic region overly broad, then (iii) the state state(s) in which you regularly worked during the two years immediately prior to the Date of Termination.

    

---

(v) In the event you believe your activity in violation of these Restrictive Covenants would not harm the Company’s legitimate business interests, you may request that the Company waive the restrictions contained in this paragraph. Any such request shall be made in writing to the Company, c/o Hubbell Incorporated, 40 Waterview Drive, Shelton, CT 06484-1000, Attention: General Counsel, and shall identify the business with whom/which you seek to associate and describe the duties that you seek to perform. The Company has the sole discretion whether to grant such a waiver and no waiver of any restrictions under this provision shall be effective unless in writing and signed by an authorized representative of the Company.

(vi) You agree that the time, geographic, and scope limitations of the Restrictive Covenants are reasonable and necessary to protect the Company’s confidential information, trade secrets, and goodwill.

(vii) The terms of the Restrictive Covenants are severable. Any term or provision of the Restrictive Covenants that is held to be invalid or unenforceable shall be ineffective to the extent of that invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of the Restrictive Covenants or affecting the validity or enforceability of any of the terms or provisions of the Restrictive Covenants. If any provisions of the Restrictive Covenants are deemed to exceed the time, geographic, or scope limitations permitted by applicable law, then such provisions shall be reformed to the maximum time, geographic, or scope limitations permissible. The Company expressly reserves the right to limit the scope of those covenants unilaterally.

(viii) The Restricted Period shall not expire, and shall be tolled, during any period in which you are in violation of any of the Restrictive Covenants set forth above.

(ix) You acknowledge and agree that (i) any breach or threatened breach of the Restrictive Covenants would cause irreparable harm to the Company, and (ii) monetary damages alone would not be an adequate remedy because they would be difficult or impossible to measure. Therefore, you further acknowledge and agree that in the case of any breach or threatened breach of the Restrictive Covenants, the Company shall be entitled to extraordinary relief, such as a temporary restraining order or injunction, in addition to any other available rights and remedies, including, but not limited to, any forfeiture or recoupment of any Award as described below.

(x) You agree that, if at any time following the date hereof you are found to have breached any Restrictive Covenant, you will pay the Company, in addition to any damages that may be awarded by the court or any forfeiture or recoupment of any Award, reasonable attorneys’ fees incurred by the Company to establish that breach, to obtain injunctive relief, and/or otherwise to enforce the Restrictive Covenants. You acknowledge that the Company shall be entitled to recover from you its reasonable attorneys’ fees if you unsuccessfully challenge the enforceability of the Restricted Covenants.

(xi) You agree that references to the Company in the Restrictive Covenants includes the “Company and its Subsidiaries” and that the scope of the foregoing and referenced agreements is reasonable and necessary in order to protect the interests of the Company and its Subsidiaries, and that the consideration to you with respect to the Restrictive Covenants was sufficient.

You agree and acknowledge that in addition to any injunctive relief to the Company, and notwithstanding anything in the Plan or this Agreement to the contrary, the Company may cause this Award to be forfeited and/or recouped (that is, returned to) the Company if you, during employment or service, or during the Restricted Period, engage in certain specified conduct,

    

---

including but not limited to breach of (x) any of the Restrictive Covenants set forth above, (y) any non-solicitation, non-competition, confidentiality or other restrictive covenant agreement with the Company or any of its Subsidiaries, or (z) any other conduct by you that is determined by the Company to be detrimental to the business or reputation of the Company or any affiliate. In addition, without limiting the effect of the foregoing, as a condition to the grant of the Award or to the applicable restrictions lapsing or any other benefit under the Award, you agree to abide by any compensation recovery policy and/or other policies adopted by the Company, Subsidiary, or an affiliate, each as in effect from time to time and to the extent applicable to you. Further, you shall be subject to such compensation recovery, recoupment, forfeiture or other similar provisions as may apply under applicable law.

By electronically acknowledging and accepting this Award, you agree that your right to the applicable restrictions on the Award lapsing or any other benefit under the Award, or any portion thereof, is subject to you not having violated the foregoing Restrictive Covenants at any time during the term of the Award, and your acceptance of the applicable restrictions of the Award lapsing shall constitute your certification to the Company that you have not violated and will not violate the Restrictive Covenants at any time during the term of the Award.

Nothing in the Plan or this Agreement shall be interpreted to interfere with or limit in any way the right of the Company or any Subsidiary to terminate your employment or services at any time, nor confer upon you the right to continue in the employ or service of the Company or any Subsidiary.

This Award is granted under and governed by the terms and conditions of the Plan. You acknowledge and agree that the Plan has been introduced voluntarily by the Company and in accordance with its terms it may be amended, cancelled, or terminated by the Company, in its sole discretion, at any time. This Award under the Plan is a one-time benefit and does not create any contractual or other right to receive an award of Stock Appreciation Rights or benefits in lieu of such Award in the future. Future awards, if any, will be at the sole discretion of the Company, including, but not limited to, the timing of the award, the number of shares and vesting provisions.

This Award shall be governed by Connecticut law without regard to choice of law principles.

This excludes temporary equity and is sometimes called permanent equity. + References Reference 1: http://www.xbrl.org/2009/role/commonPracticeRef -Publisher FASB -Name Accounting Standards Codification -Topic 235 -SubTopic 10 -Section S99 -Paragraph 1 -Subparagraph (SX 210.4-08(g)(1)(ii)) -URI https://asc.fasb.org/extlink&oid=120395691&loc=d3e23780-122690 Reference 2: http://www.xbrl.org/2003/role/exampleRef -Publisher FASB -Name Accounting Standards Codification -Topic 852 -SubTopic 10 -Section 55 -Paragraph 10 -URI https://asc.fasb.org/extlink&oid=84165509&loc=d3e56426-112766 Reference 3: http://fasb.org/us-gaap/role/ref/legacyRef -Publisher FASB -Name Accounting Standards Codification -Topic 310 -SubTopic 10 -Section S99 -Paragraph 2 -Subparagraph (SAB Topic 4.E) -URI https://asc.fasb.org/extlink&oid=122038336&loc=d3e74512-122707 Reference 4: http://fasb.org/us-gaap/role/ref/legacyRef -Publisher FASB -Name Accounting Standards Codification -Topic 210 -SubTopic 10 -Section S99 -Paragraph 1 -Subparagraph (SX 210.5-02(31)) -URI https://asc.fasb.org/extlink&oid=120391452&loc=d3e13212-122682 Reference 5: http://fasb.org/us-gaap/role/ref/legacyRef -Publisher FASB -Name Accounting Standards Codification -Topic 210 -SubTopic 10 -Section S99 -Paragraph 1 -Subparagraph (SX 210.5-02(29)) -URI https://asc.fasb.org/extlink&oid=120391452&loc=d3e13212-122682 Reference 6: http://fasb.org/us-gaap/role/ref/legacyRef -Publisher FASB -Name Accounting Standards Codification -Topic 210 -SubTopic 10 -Section S99 -Paragraph 1 -Subparagraph (SX 210.5-02(30)) -URI https://asc.fasb.org/extlink&oid=120391452&loc=d3e13212-122682 Reference 7: http://www.xbrl.org/2009/role/commonPracticeRef -Publisher FASB -Name Accounting Standards Codification -Topic 825 -SubTopic 10 -Section 50 -Paragraph 28 -Subparagraph (f) -URI https://asc.fasb.org/extlink&oid=123596393&loc=d3e14064-108612 Reference 8: http://www.xbrl.org/2009/role/commonPracticeRef -Publisher FASB -Name Accounting Standards Codification -Topic 323 -SubTopic 10 -Section 50 -Paragraph 3 -Subparagraph (c) -URI https://asc.fasb.org/extlink&oid=114001798&loc=d3e33918-111571 + Details Name: us-gaap_StockholdersEquity Namespace Prefix: us-gaap_ Data Type: xbrli:monetaryItemType Balance Type: credit Period Type: instant

Significant Accounting Policies	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies   Basis of Presentation   The accompanying consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). On February 1, 2022, the Company completed the sale of the Commercial and Industrial Lighting business (the "C&I Lighting business") to GE Current, a Daintree Company, for total net cash consideration of $332.8 million. The C&I Lighting business had sales of $509.4 million in 2021 as part of the Electrical Solutions segment and designs, manufactures, and sells LED lighting and control solutions for commercial and industrial customers. As a result of the agreement, the C&I Lighting business met the criteria set forth in ASC 205-20 to be presented as a discontinued operation. The C&I Lighting business' results of operations and the related cash flows have been presented as income from discontinued operations in the Consolidated Statements of Income and cash flows from discontinued operations in the Consolidated Statements of Cash Flows, respectively, for all periods presented. See Note 2, Discontinued Operations, to the Consolidated Financial Statements for further information. Principles of Consolidation   The Consolidated Financial Statements include all wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated. The Company participates in two joint ventures that have been consolidated in accordance with the consolidation accounting guidance. An analysis is performed to determine which reporting entity, if any, has a controlling financial interest in a variable interest entity (“VIE”) with a primarily qualitative analysis. The qualitative analysis is based on identifying the party that has both the power to direct the activities that most significantly impact the VIE’s economic performance (the “power criterion”) and the obligation to absorb losses from or the right to receive benefits of the VIE that could potentially be significant to the VIE (the “losses/benefit criterion”). The party that meets both these criteria is deemed to have a controlling financial interest. The party with the controlling financial interest is considered to be the primary beneficiary and as a result is required to consolidate the VIE. The Company has a 50% interest in a joint venture in Hong Kong, established as Hubbell Asia Limited (“HAL”). The principal objective of HAL is to manage the operations of its wholly-owned manufacturing company in China. Under the accounting guidance, the Company is the primary beneficiary of HAL and as a result consolidates HAL. This determination is based on the fact that HAL’s sole business purpose is to manufacture product exclusively for the Company (the power criterion) and the Company is financially responsible for ensuring HAL maintains a fixed operating margin (the losses/benefit criterion). The consolidation of HAL is not material to the Company’s consolidated financial statements. Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts in the Consolidated Financial Statements and accompanying Notes to Consolidated Financial Statements. Actual results could differ from the estimates that are used. Impact of the COVID-19 Pandemic During March 2020, a global pandemic was declared by the World Health Organization related to the rapidly growing outbreak of a novel strain of coronavirus (COVID-19). The pandemic has had, and may continue to have, a significant effect on global economic conditions. U.S. Federal, state, local, and foreign governments have reacted to the public health crisis with mitigation measures, creating significant uncertainties in the U.S. and global economies. The extent to which the coronavirus pandemic will continue to affect our business, operations, supply chains, and our financial results will depend on numerous evolving factors that we may not be able to accurately predict and which may cause the actual results to differ from the estimates and assumptions we are required to make in the preparation of financial statements according to GAAP. Assets and Liabilities Held for Sale The Company classifies assets and liabilities (disposal groups) to be sold as held for sale in the period in which all of the following criteria are met: management, having the authority to approve the action, commits to a plan to sell the disposal group; the disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such disposal groups; an active program to locate a buyer and other actions required to complete the plan to sell the disposal group have been initiated; the sale of the disposal group is probable, and transfer of the disposal group is expected to qualify for recognition as a completed sale within one year, except if events or circumstances beyond the Company's control extend the period of time required to sell the disposal group beyond one year; the disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. The Company initially measures a disposal group that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a disposal group until the date of sale. The Company assesses the fair value of a disposal group, less any costs to sell, each reporting period it remains classified as held for sale and reports any subsequent changes as an adjustment to the carrying value of the disposal group, as long as the new carrying value does not exceed the carrying value of the disposal group at the time it was initially classified as held for sale. Upon determining that a disposal group meets the criteria to be classified as held for sale, the Company reports the assets and liabilities of the disposal group, if material, in the line items assets held for sale and liabilities held for sale in the consolidated statements of financial position. Refer to Note 2, "Discontinued Operations," of the notes to Consolidated Financial Statements for further information. In conjunction with the C&I Lighting Business being classified as held for sale, depreciation and amortization ceased.   Revenue Recognition   The Company recognizes revenue when performance obligations identified under the terms of contracts with its customers are satisfied, which generally occurs, for products, upon the transfer of control in accordance with the contractual terms and conditions of the sale. The majority of the Company’s revenue associated with products is recognized at a point in time when the product is shipped to the customer, with a relatively small amount of transactions in the Utility Solutions segment recognized upon delivery of the product at the contractually specified destination. Revenue from service contracts and post-shipment performance obligations is approximately two percent of total annual consolidated net revenue and those service contracts and post-shipment obligations are primarily within the Utility Solutions segment. Revenue from service contracts and post-shipment performance obligations is recognized when or as those obligations are satisfied. The Company primarily offers assurance-type standard warranties that do not represent separate performance obligations and on occasion will separately offer and price extended warranties that are separate performance obligations for which the associated revenue is recognized over-time based on the extended warranty period. The Company records amounts billed to customers for reimbursement of shipping and handling costs within revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as fulfillment costs and are included in cost of goods sold. Sales taxes and other usage-based taxes are excluded from revenue. Within the Electrical Solutions segment, certain businesses require a portion of the transaction price to be paid in advance of transfer of control. Advance payments are not considered a significant financing component as they are received less than one year before the related performance obligations are satisfied. In addition, in the Utility Solutions segment, certain businesses offer annual maintenance service contracts that require payment at the beginning of the contract period. These payments are treated as a contract liability and are classified in Other accrued liabilities in the Consolidated Balance Sheet. Once control transfers to the customer and the Company meets the revenue recognition criteria, the deferred revenue is recognized in the Consolidated Statement of Income. The deferred revenue relating to the annual maintenance service contracts is recognized in the Consolidated Statement of Income on a straight line basis over the expected term of the contract. The Company has certain arrangements that require us to estimate at the time of sale the amounts of variable consideration that should not be recorded as revenue as certain amounts are not expected to be collected from customers, as well as an estimate of the value of the product to be returned. The Company principally relies on historical experience, specific customer agreements and anticipated future trends to estimate these amounts at the time of shipment and to reduce the transaction price. These arrangements include sales discounts and allowances based on sales volumes, specific programs and special pricing allowances, and returned goods, as are customary in the electrical products industry. Customer returns have historically been approximately 1% of gross sales. Shipping and Handling Costs   The Company records shipping and handling costs as part of Cost of goods sold in the Consolidated Statement of Income.   Foreign Currency Translation   The assets and liabilities of international subsidiaries are translated to U.S. dollars at exchange rates in effect at the end of the year, and income and expense items are translated at average exchange rates in effect during the year. The effects of exchange rate fluctuations on the translated amounts of foreign currency assets and liabilities are included as translation adjustments in Accumulated other comprehensive loss within Hubbell shareholders’ equity. Gains and losses from foreign currency transactions are included in results of operations.   Cash and Cash Equivalents   The carrying value of cash equivalents approximates fair value. Cash equivalents consist of highly liquid investments with original maturities to the Company of three months or less.   Investments   Investments in debt and equity securities are classified by individual security as available-for-sale, held-to-maturity or trading securities. Our available-for-sale securities, consisting of municipal bonds, are carried on the balance sheet at fair value with current period adjustments to carrying value recorded in Accumulated other comprehensive loss within Hubbell shareholders’ equity, net of tax. Realized gains and losses are recorded in income in the period of sale. The Company’s trading securities are carried on the balance sheet at fair value and consist primarily of debt and equity mutual funds. Gains and losses associated with these trading securities are reflected in the results of operations. The Company did not have any investments classified as held-to-maturity as of December 31, 2022 and 2021.   Accounts Receivable and Allowances   Trade accounts receivable are recorded at the invoiced amount and generally do not bear interest. The allowance for doubtful accounts is based on an estimated amount of probable credit losses in existing accounts receivable. The allowance is calculated based upon a combination of historical write-off experience, fixed percentages applied to aging categories and specific identification based upon a review of past due balances and problem accounts. Account balances are charged off against the allowance when it is determined that internal collection efforts should no longer be pursued. The Company also maintains a reserve for credit memos and cash discounts which are principally calculated based upon historical experience, specific customer agreements, as well as anticipated future trends.   Inventories   Inventories are stated at the lower of cost or market value. Approximately 60% of total net inventory value is determined utilizing the last-in, first-out (LIFO) method of inventory accounting. The cost of foreign inventories and certain domestic inventories is determined utilizing average cost or first-in, first-out (FIFO) methods of inventory accounting. Reserves for excess and obsolete inventory are provided based on current assessments about future demand compared to on-hand quantities. Property, Plant, and Equipment   Property, plant, and equipment values are stated at cost less accumulated depreciation. Maintenance and repair expenditures that do not significantly increase the life of an asset are charged to expense when incurred. Property, plant, and equipment placed in service prior to January 1, 1999 are depreciated over their estimated useful lives, principally, using accelerated methods. Assets placed in service subsequent to January 1, 1999 are depreciated over their estimated useful lives, using straight-line methods. Leasehold improvements are amortized over the shorter of their economic lives or the lease term. Gains and losses arising on the disposal of property, plant and equipment are included in Operating income in the Consolidated Statement of Income.   Capitalized Computer Software Costs   Capitalized computer software costs, net of amortization, were $7.0 million and $10.8 million at December 31, 2022 and 2021, respectively. This balance is reflected in Other long-term assets in the Consolidated Balance Sheet. Capitalized computer software is for internal use and costs primarily consist of purchased materials, external services and salary costs for personnel dedicated to the projects. Software is amortized on a straight-line basis over appropriate periods, generally between three and five years. The Company recorded amortization expense of $6.6 million in 2022, $9.6 million in 2021 and $10.0 million in 2020 relating to capitalized computer software.   Goodwill and Other Intangible Assets   Goodwill represents purchase price in excess of fair values of the underlying net assets of acquired companies. Indefinite-lived intangible assets and goodwill are subject to annual impairment testing using the specific guidance and criteria described in the accounting guidance. The Company performs its goodwill impairment testing as of April 1st of each year, unless circumstances dictate the need for more frequent assessments. The accounting guidance provides entities an option of performing a qualitative assessment (a "step-zero" test) before performing a quantitative analysis. If the entity determines, on the basis of certain qualitative factors, that it is more-likely-than-not that the goodwill is not impaired, the entity would not need to proceed to quantitative goodwill impairment testing process as prescribed in the guidance. The Company applied the "step-zero" test to one of its four reporting units. Based on that qualitative assessment, the Company concluded it was more-likely-than-not that the fair value of this reporting unit exceeded its carrying value and therefore, further quantitative analysis was not required. For the other three reporting units the Company has elected to utilize the quantitative goodwill impairment testing process as permitted in the accounting guidance, by comparing the estimated fair value of the Company's reporting units to their carrying values. If the fair value of the reporting unit exceeds its carrying value, no impairment exists.   Goodwill impairment testing requires judgment, including the identification of reporting units, assigning assets and liabilities to reporting units and determining the fair value of each reporting unit. Significant judgments required to estimate the fair value of reporting units include estimating future discounted cash flows, determining appropriate discount rates and other assumptions, including assumptions about secular economic and market conditions, such as the potential continuing effects of the COVID-19 pandemic, impacts to the supply chain and higher inflation. We use internal discounted cash flow models to estimate fair value. These cash flow estimates are derived from historical experience, third party end market data, and future long-term business plans and include assumptions on future sales growth, gross margin, operating margin, terminal growth rate, and the application of an appropriate discount rate. Changes in these estimates and assumptions could affect the determination of fair value and/or goodwill impairment for each reporting unit. The Company believes that its estimated aggregate fair value of its reporting units is reasonable when compared to the Company's market capitalization on the valuation date. On January 1, 2022, we internally reorganized certain businesses within our Electrical Solutions segment to simplify the organization structure and align the organization to better serve our customers. This change had no impact to our reportable segments. As a result of the change in reporting units, the Company performed an interim goodwill impairment assessment prior to the change, for the reporting units within the Electrical Solutions segment. Because the changes did not affect the Utility Solutions segment, no interim goodwill impairment assessment was required for that segment. As of April 1, 2022, the impairment testing resulted in implied fair values of our reporting units that exceeded the reporting unit's carrying value, including goodwill. The range of fair value in excess of carrying value, including goodwill, of the reporting units was 57% to 308%. Additionally, the Company did not have any reporting units with zero or negative carrying amounts. The Company has not recorded any goodwill impairments since the initial adoption of the accounting guidance in 2002. The Company’s intangible assets consist primarily of customer relationships, tradenames, developed technology and patents. Intangible assets with definite lives are amortized over periods generally ranging from 5-30 years. The Company amortizes intangible assets with definite lives using either an accelerated method that reflects the pattern in which economic benefits of the intangible assets are consumed and results in higher amortization in the earlier years of the assets' useful life, or using a straight line method. Approximately 80% of the gross value of definite-lived intangible assets follow an accelerated amortization method. These definite lived intangibles are tested for impairment whenever events or circumstances indicate that the carrying amount of an asset (asset group) may not be recoverable. An impairment loss is recognized when the carrying amount of an asset exceeds the estimated undiscounted cash flows used in determining the fair value of the asset. The Company did not record any material impairments related to its definite lived intangible assets in 2022, 2021 or 2020. The Company also has some tradenames that are considered to be indefinite-lived intangible assets. These indefinite-lived intangible assets are not amortized and are tested for impairment annually, unless circumstances dictate the need for more frequent assessment.   The identification and measurement of impairment of indefinite-lived intangible assets involves either an assessment of qualitative factors to determine whether events or circumstances indicate that it is more-likely-than-not that an indefinite-lived intangible asset is impaired or a quantitative assessment whereby the estimated fair value of each indefinite-lived intangible asset is compared to its carrying value. If it is more-likely-than-not that the asset is impaired, the fair value of the indefinite lived intangibles will be determined using discounted cash flow estimates. If the carrying value of these assets exceeds the estimated fair value, the carrying value will be reduced to the estimated fair value. For the Company’s annual impairment test as of April 1, 2022, the Company elected to utilize the quantitative impairment testing process as permitted in the accounting guidance. The fair value was determined utilizing an income approach (relief from royalty method). Significant judgment is required to estimate the fair value of the indefinite-lived intangible assets including assumptions for future revenues, discount rates, royalty rates, and other assumptions, including assumptions about secular economic and market conditions, such as the potential continuing effects of the COVID-19 pandemic. Significant changes in these estimates and assumptions could affect the determination of fair value and/or impairment for each indefinite-lived intangible asset. As of April 1, 2022, the impairment testing resulted in fair values for each indefinite-lived intangible asset that significantly exceeded the carrying values and there were no indefinite-lived intangible assets at risk of failing the quantitative impairment test. The Company did not record any impairments related to indefinite-lived intangible assets in 2022, 2021 and 2020.   Other Long-Lived Assets   The Company reviews depreciable long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. If such a change in circumstances occurs, the related estimated future undiscounted cash flows expected to result from the use of the asset group and its eventual disposition is compared to the carrying amount. If the sum of the expected cash flows is less than the carrying amount, an impairment charge is recorded. The impairment charge is measured as the amount by which the carrying amount exceeds the fair value of the asset. The fair value of impaired assets is determined using expected cash flow estimates, quoted market prices when available and appraisals as appropriate. The Company did not record any material impairment charges in 2022, 2021 or 2020.   Leases   We determine if an arrangement is a lease at inception. Operating leases are included as ROU assets within other long-term assets, other accrued liabilities, and other non-current liabilities in our Consolidated Balance Sheets. Finance leases are included in property, plant, and equipment, net, other accrued liabilities, and other non-current liabilities. The Company's finance leases are immaterial. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. We use an implicit rate when readily determinable. For leases existing as of January 1, 2019, we have elected to use the remaining lease term as of the adoption date in determining the incremental borrowing rate. Our determination of the lease term may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. We have lease agreements with lease and non-lease components, which are generally accounted for separately. Additionally, for our vehicle leases, we apply a portfolio approach regarding the assumed lease term. Accrued Insurance  The Company retains a significant portion of the risks associated with workers’ compensation, medical, automobile and general liability insurance. The Company estimates self-insurance liabilities using a number of factors, including historical claims experience, demographic factors, and other actuarial assumptions. The accrued liabilities associated with these programs are based on the Company’s estimate of the ultimate costs to settle known claims as well as claims incurred but not reported as of the balance sheet date. The Company periodically reviews the assumptions with a third party actuary to determine the adequacy of these self-insurance reserves. Accrued Warranty The Company offers product warranties which cover defects on most of its products. These warranties primarily apply to products that are properly installed, maintained and used for their intended purpose. The Company accrues estimated warranty costs at the time of sale. Estimated warranty expenses, recorded in cost of goods sold, are based upon historical information such as past experience, product failure rates, or the estimated number of units to be repaired or replaced. Adjustments are made to the product warranty accrual as claims are incurred, additional information becomes known or as historical experience indicates. Income Taxes   The Company operates within multiple taxing jurisdictions and is subject to audit in these jurisdictions. The IRS and other tax authorities routinely examine the Company’s tax returns. These audits can involve complex issues which may require an extended period of time to resolve. The Company makes adequate provisions for best estimates of exposures on previously filed tax returns. Deferred income taxes are recognized for the tax consequence of differences between financial statement carrying amounts and the tax basis of assets and liabilities by applying the currently enacted statutory tax rates in accordance with the accounting guidance for income taxes. The effect of a change in statutory tax rates is recognized in the period that includes the enactment date. Additionally, deferred tax assets are required to be reduced by a valuation allowance if it is more-likely-than-not that a portion or all of the deferred tax asset will not be realized. The Company uses factors to assess the likelihood of realization of deferred tax assets such as the forecast of future taxable income and available tax planning that could be implemented to realize the deferred tax assets.   In addition, the accounting guidance prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of the tax position taken or expected to be taken in a tax return. For any amount of benefit to be recognized, it must be determined that it is more-likely-than-not that a tax position will be sustained upon examination by taxing authorities based on the technical merits of the position. The amount of benefit to be recognized is based on the Company’s assertion of the most likely outcome resulting from an examination, including resolution of any related appeals or litigation processes. Companies are required to reflect only those tax positions that are more-likely-than-not to be sustained. See Note 14 — Income Taxes for additional information.   Research and Development   Research and development expenditures represent costs to discover and/or apply new knowledge in developing a new product, process, or in bringing about a significant improvement to an existing product or process. Research and development expenses are recorded as a component of Cost of goods sold. Expenses for research and development were approximately 2% of Net Sales in each of 2022 and 2021 and 3% in 2020.   Government Assistance   We have adopted Accounting Standards Update ("ASU") 2021-10, Government Assistance (Topic 832) Disclosures by Business Entities about Government Assistance, which requires footnote disclosure of assistance received from government entities. We record amounts received from government entities as a reduction of the associated expense. Amounts received related to depreciable assets are recognized as a reduction to depreciation expense. The total impact of government assistance was not material to the Company in 2022, and prior periods presented. Retirement Benefits The Company maintains various defined benefit pension plans for some of its U.S. and foreign employees. The accounting guidance for retirement benefits requires the Company to recognize the funded status of its defined benefit pension and postretirement plans as an asset or liability in the Consolidated Balance Sheet. Gains or losses, prior service costs or credits, and transition assets or obligations that have not yet been included in net periodic benefit cost as of the end of the year are recognized as components of Accumulated other comprehensive loss, net of tax, within Hubbell shareholders’ equity. The Company’s policy is to fund pension costs within the ranges prescribed by applicable regulations. In addition to providing defined benefit pension benefits, the Company provides health care and life insurance benefits for some of its active and retired employees. The Company’s policy is to fund these benefits through insurance premiums or as actual expenditures are made. See also Note 12 — Retirement Benefits.   Earnings Per Share   Restricted stock granted by the Company is considered a participating security since it contains a non-forfeitable right to dividends. As a result, the earnings per share accounting guidance requires the Company to use the two-class method for calculating earnings per share. The two-class method is an earnings allocation formula that determines earnings per share for common stock and participating securities. Basic earnings per share is calculated as net income available to common shareholders divided by the weighted average number of shares of common stock outstanding. Earnings per diluted share is calculated as net income available to common shareholders divided by the weighted average number of shares outstanding of common stock plus the incremental shares outstanding assuming the exercise of dilutive stock options, stock appreciation rights and performance shares. See also Note 19 — Earnings Per Share.   Stock-Based Compensation   The Company recognizes the grant-date fair value of all stock-based awards on a straight-line basis over their respective requisite service periods (generally equal to an award’s vesting period). A stock-based award is considered vested for expense attribution purposes when the retention of the award is no longer contingent on providing subsequent service. Accordingly, the Company generally recognizes compensation cost immediately for awards granted to retirement-eligible individuals or over the period from the grant date to the date retirement eligibility is achieved, if less than the stated vesting period. The expense is recorded in Cost of goods sold and S&A expense in the Consolidated Statement of Income based on the recipients’ respective functions within the organization.   The Company records deferred tax assets for awards that will result in deductions on its tax returns, based upon the amount of compensation cost recognized and the statutory tax rate in the jurisdiction in which it will receive a deduction. See also Note 18 — Stock-Based Compensation. Recently Issued Accounting Pronouncements In March 2020, the FASB issued ASU No. 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting", which provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments are effective for all entities beginning on March 12, 2020 through December 31, 2022. The Company may elect to apply the amendments prospectively through December 31, 2022. In December 2022, the FASB issued ASU No. 2022-06 Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which extends the temporary accounting rules under Topic 848 to December 31, 2024. The Company is currently assessing the impact of adopting this standard on its financial statements and the timing of adoption.

Discontinued Operations	12 Months Ended
	Dec. 31, 2022
Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations   On February 1, 2022, the Company completed the sale of the C&I Lighting business to GE Current, a Daintree Company, for total net cash consideration of $332.8 million. We have concluded the divestiture of this business represents a strategic shift that will have a major effect on our operations and financial results, and as a result, is reported as a discontinued operation in our Consolidated Financial Statements for all periods presented. The assets and liabilities of this business are also presented as held for sale in the Consolidated Balance Sheets for the year ended December 31, 2021. The C&I Lighting business was previously included in the Electrical Solutions segment. Under the terms of the transaction, Hubbell and the buyer entered into a transition services agreement ("TSA"), pursuant to which the Company provides certain administrative and operational services for a period of 12 months or less. Furthermore, we entered into a short-term supply agreement whereby the Company acts as a supplier of finished goods and component parts to the C&I Lighting business after the completion of the sale. Income from the TSA and supply agreement was $13.3 million for the year ended December 31, 2022 and was recorded in Other Income in the Consolidated Financial Statements. The following table presents the summarized components of income from discontinued operations, net of income taxes, for the Commercial and Industrial Lighting business:   Year Ended December 31, (in millions) 2022 2021 2020 Net sales $ 29.1  $ 509.4  $ 503.5  Cost of goods sold 27.8  403.4  385.6  Gross profit 1.3  106.0  117.9  Selling & administrative expenses 17.3  88.5  85.1  Operating (Loss) income (16.0) 17.5  32.8  Gain on disposal of business 73.9  —  —  Other expense (1.5) (4.1) (4.0) Income from discontinued operations before income taxes 56.4  13.4  28.8  Provision (benefit) for income taxes 21.8  (21.1) 7.6  Income from discontinued operations, net of taxes $ 34.6  $ 34.5  $ 21.2  Income from discontinued operations, net of taxes for the year ended December 31, 2022 and December 31, 2021 includes pre-tax transaction and separation costs of $8.8 million and $7.0 million, respectively. The provision for income taxes on discontinued operations in 2022 includes a correction of $19 million of income tax expense recognized in the fourth quarter of 2022 that should have been recognized in the first quarter of 2022. The Company evaluated the materiality of the adjustment to prior-period financial statements and concluded the effect of the adjustment was immaterial. In addition, a one-time tax benefit of $25.1 million related to book-to-tax basis differences of the business was recorded in the year ended December 31, 2021. The following table presents balance sheet information for assets and liabilities held for sale: At December 31, (in millions) 2021 Cash and cash equivalents $ 0.7  Accounts receivable 83.1  Inventories, net 89.8  Other current assets 5.9  Assets held for sale - current $ 179.5  Property, Plant, and Equipment, net 77.7  Goodwill 50.2  Other Intangible assets, net 37.3  Other long-term assets 11.9  Assets held for sale - non-current $ 177.1  Accounts payable 50.2  Accrued salaries, wages and employee benefits 8.5  Accrued insurance 3.9  Other accrued liabilities 28.7  Liabilities held for sale - current $ 91.3  Other Non-Current Liabilities 18.8  Liabilities held for sale - non-current $ 18.8

Revenue	12 Months Ended
	Dec. 31, 2022
Revenue from Contract with Customer [Abstract]
Revenue	Revenue   The Company recognizes revenue when performance obligations identified under the terms of contracts with its customers are satisfied, which generally occurs, for products, upon the transfer of control in accordance with the contractual terms and conditions of the sale. Approximately three-fourths of the Company's Net sales are to distributors who then sell directly into our end markets. Within the Utility Solutions segment, our businesses sell to distributors, with the majority of sales to the utility end markets and also directly into transmission and distribution utility markets. The majority of the Company’s revenue associated with products is recognized at a point in time when the product is shipped to the customer, with a relatively small amount of transactions, primarily in the Utility Solutions segment, recognized upon delivery of the product at the destination. Revenue from service contracts and post-shipment performance obligations is recognized when or as those obligations are satisfied. The Company primarily offers assurance-type standard warranties that do not represent separate performance obligations and on occasion will separately offer and price extended warranties that are separate performance obligations for which the associated revenue is recognized over-time based on the extended warranty period. The Company records amounts billed to customers for reimbursement of shipping and handling costs within revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as fulfillment costs and are included in cost of goods sold. Sales taxes and other usage-based taxes are excluded from revenue. Within the Electrical Solutions segment, certain businesses require a portion of the transaction price to be paid in advance of transfer of control. Advance payments are not considered a significant financing component as they are received less than one year before the related performance obligations are satisfied. In addition, in the Utility Solutions segment, certain businesses offer annual maintenance service contracts that require payment at the beginning of the contract period. These payments are treated as a contract liability and are classified in Other accrued liabilities in the Consolidated Balance Sheets. Once control transfers to the customer and the Company meets the revenue recognition criteria, the deferred revenue is recognized in the Consolidated Statements of Income. The deferred revenue relating to the annual maintenance service contracts is recognized in the Consolidated Statements of Income on a straight-line basis over the expected term of the contract. The following table presents disaggregated revenue by business group. On January 1, 2022, we internally reorganized certain businesses within our Electrical Solutions segment to simplify the organization structure and align the organization to better serve our customers. This change had no impact to our reportable segments. In conjunction with this change, prior period amounts have been reclassified to conform to the organizational changes within the Electrical Solutions segment. Twelve Months Ended December 31, in millions 2022 2021 2020 Net sales    Utility T&D Components $ 2,218.8  $ 1,679.8  $ 1,445.1     Utility Communications and Controls 652.3  654.6  634.3  Total Utility Solutions $ 2,871.1  $ 2,334.4  $ 2,079.4     Electrical Products 902.4  809.6  663.9     Connection and Bonding 608.7  525.3  430.2     Industrial Controls 337.7  257.8  236.2     Retail and Builder 228.0  267.0  272.8  Total Electrical Solutions $ 2,076.8  $ 1,859.7  $ 1,603.1  TOTAL $ 4,947.9  $ 4,194.1  $ 3,682.5  The following table presents disaggregated third-party Net sales by geographic location (on a geographic basis, the Company defines "international" as operations based outside of the United States and its possessions): Twelve Months Ended December 31, in millions 2022 2021 2020 Net sales      United States $ 2,715.8  $ 2,204.9  $ 1,967.9       International 155.3  129.5  111.5  Total Utility Solutions $ 2,871.1  $ 2,334.4  $ 2,079.4  United States 1,820.6  1,604.9  1,389.0  International 256.2  254.8  214.1  Total Electrical Solutions $ 2,076.8  $ 1,859.7  $ 1,603.1  TOTAL $ 4,947.9  $ 4,194.1  $ 3,682.5  Contract Balances Our contract liabilities consist of advance payments for products as well as deferred revenue on service obligations and extended warranties. The current portion of deferred revenue is included in Other accrued liabilities and the non-current portion of deferred revenue is included in Other non-current liabilities in the Consolidated Balance Sheet. Contract liabilities were $45.8 million as of December 31, 2022 compared to $16.7 million as of December 31, 2021. The $29.1 million increase in our contract liabilities balance was primarily due to a $21.8 million net increase in current year deferrals primarily due to timing of advance payments on certain orders and a $20.1 million increase due to acquisitions, partially offset by the recognition of $12.8 million in revenue related to amounts that were recorded in contract liabilities at January 1, 2022. The Company has an immaterial amount of contract assets relating to performance obligations satisfied prior to payment that is recorded in Other long-term assets in the Condensed Consolidated Balance Sheets. Impairment losses recognized on our receivables and contract assets were immaterial in the twelve months ended December 31, 2022. See Note 1 – Significant Accounting Policies in the Notes to Consolidated Financial Statements for additional information. Unsatisfied Performance Obligations The Company has elected the practical expedient to disclose only the value of unsatisfied performance obligations for contracts with an original expected length greater than one year. As of December 31, 2022, the Company had approximately $320 million of unsatisfied performance obligations for contracts with an original expected length of greater than one year, primarily relating to long-term contracts of the Aclara business (within the Utility Solutions segment) to deliver and install meters, metering communications and grid monitoring sensor technology. The Company expects that a majority of the unsatisfied performance obligations will be completed and recognized over the next 2 years.

Business Acquisitions and Dispositions	12 Months Ended

Business Combination and Asset Acquisition [Abstract]
Business Acquisitions and Dispositions	Business Acquisitions and Dispositions  2022 Acquisitions In the third quarter of 2022, the Company acquired all of the issued and outstanding membership interests of PCX Holdings LLC ("PCX") for a cash purchase price of approximately $112.8 million, net of cash acquired. PCX is a leading designer and manufacturer of factory built modular power solutions for applications in the data center market. This business is reported in the Electrical Solutions segment. We have recognized intangible assets of $49.1 million and goodwill of $77.4 million as a result of this acquisition. The intangible assets of $49.1 million consist primarily of customer relationships, backlog and a tradename and will be amortized over a weighted average period of approximately 11 years. All of the goodwill is expected to be deductible for tax purposes. In the third quarter of 2022, the Company also acquired all of the issued and outstanding membership interests of Ripley Tools, LLC and Nooks Hill Road, LLC, collectively referred to as Ripley Tools, for a cash purchase price of approximately $50.1 million, net of cash acquired. Ripley Tools is a leading manufacturer of cable and fiber prep tools and test equipment that services both the utility and communications markets. This business is reported in the Utility Solutions segment. We have recognized intangible assets of $18.2 million and goodwill of $23.8 million as a result of this acquisition. The intangible assets of $18.2 million consist primarily of customer relationships and a tradename, and will be amortized over a weighted average period of approximately 17 years. Substantially all of the goodwill is expected to be deductible for tax purposes. In the fourth quarter of 2022, the Company also acquired all of the issued and outstanding equity interests of REF Automation Limited and REF Alabama Inc. (collectively "REF") for a cash purchase price of $14.1 million, net of cash acquired, subject to customary purchase price adjustments. REF designs and manufactures electrical power components utilizing high-volume precision machining, as well as custom fabricated structural products and assemblies for the OEM, industrial and renewables markets. This business is reported in the Electrical Solutions segments. We have recognized goodwill of $10.2 million as a result of the acquisition. None of the goodwill associated with this acquisition is expected to be deductible for tax purposes. These business acquisitions have been accounted for as business combinations and have resulted in the recognition of goodwill. The goodwill relates to a number of factors implied in the purchase prices, including the future earnings and cash flow potential of the businesses as well as the complementary strategic fit and resulting synergies that such business acquisitions bring to the Company’s existing operations. Allocation of Consideration Transferred to Net Assets Acquired The following table presents the determination of the fair value of identifiable assets acquired and liabilities assumed from the Company's 2022 acquisitions. Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact the Company's results of operations. The following table summarizes the fair values of the assets acquired and liabilities assumed as of the respective date of acquisition for all transactions (in millions): Tangible assets acquired $ 41.4  Intangible assets 67.3  Goodwill 111.4  Other liabilities assumed (43.0) Total Estimate of Consideration Transferred, Net of Cash Acquired 177.1  The Consolidated Financial Statements include the results of operations of the acquired businesses from their respective dates of acquisition. Net sales and earnings related to these acquisitions for the year ended December 31, 2022 were not significant to the consolidated results. Pro forma information related to these acquisitions has not been included because the impact to the Company's consolidated results of operations was not material. Dispositions In June of 2021, the Company completed the sale of the Consumer Analytics Solutions business for $9.8 million. The Consumer Analytics Solutions business was part of Aclara and was previously included in the Utility Solutions segment. Upon disposition, the Consumer Analytics Solutions business had assets of $15.9 million, including definite-lived intangibles of $8.7 million (primarily customer relationships and developed technology), goodwill of $1.9 million and total liabilities of $1.5 million (primarily composed of deferred revenue). As a result of the sale of the Consumer Analytics Solutions business, we recognized a pre-tax loss of $6.9 million that is included in Total other expense in the Consolidated Statement of Income.

Retirement Benefits	12 Months Ended
	Dec. 31, 2022
Pension and Other Postretirement Benefits Cost (Reversal of Cost) [Abstract]
Retirement Benefits	Retirement Benefits   The Company has funded and unfunded non-contributory U.S. and foreign defined benefit pension plans. Benefits under these plans are generally provided based on either years of service and final average pay or a specified dollar amount per year of service. The U.S. defined benefit pension plan has been closed to new participants since 2004, while the Canadian and UK defined benefit pension plans have been closed to new entrants since 2006 and 2007, respectively. These U.S., Canadian and UK employees are eligible instead for defined contribution plans.   The Company also has a number of health care and life insurance benefit plans covering eligible employees who reached retirement age while working for the Company. These benefits have been discontinued for substantially all future retirees. The Company anticipates future cost-sharing charges for its discontinued plans that are consistent with past practices. The Company uses a December 31 measurement date for all of its plans. In 2020 and 2022, the Company recognized a settlement loss in continuing operations relating to retirees that elected to receive lump-sum distributions from the Company's defined benefit pension plans of $7.6 million and $7.0 million, respectively. This charge was the result of lump-sum payments which exceeded the threshold for settlement accounting under U.S. GAAP in each year. In 2019, the Company approved amendments to one of its domestic qualified defined benefit pension plans, which froze service accruals for nearly all active participants within the plan effective January 1, 2020. As a result of the amendment, the Company recognized a $0.3 million curtailment charge, net of tax. Effective January 1, 2020, the amortization of unrecognized gains and losses of all of the Company's qualified defined benefit pension plans is recognized over the remaining life expectancy of participants, as nearly all participants are considered inactive as a result of plan amendments. The Company's U.S. defined benefit pension plans were approximately 90% of the $670.8 million total pension benefit obligations at December 31, 2022.  The following table sets forth the reconciliation of beginning and ending balances of the benefit obligations and the plan assets for the Company’s defined benefit pension and other benefit plans at December 31, (in millions):    Pension Benefits Other Benefits   2022 2021 2022 2021 Change in benefit obligation         Benefit obligation at beginning of year $ 937.7  $ 994.2  $ 18.9  $ 23.2  Service cost 0.9  1.0  —  —  Interest cost 28.0  23.8  0.5  0.6  Plan participants’ contributions —  —  —  —  Amendments —  3.6  —  —  Actuarial loss/(gain) (214.2) (22.0) (2.2) (4.2) Curtailment gain —  —  —  —  Settlements (22.5) (0.1) —  —  Currency impact (10.5) (0.9) —  —  Other (0.5) (0.3) —  —  Benefits paid (48.1) (61.6) (1.3) (0.7) Benefit obligation at end of year $ 670.8  $ 937.7  $ 15.9  $ 18.9  Change in plan assets Fair value of plan assets at beginning of year $ 765.6  $ 805.1  $ —  $ —  Actual return on plan assets (186.6) 15.6  —  —  Employer contributions 19.8  7.9  1.3  0.7  Plan participants’ contributions —  —  —  —  Settlements (22.5) (0.1) —  —  Currency impact (12.8) (1.3) —  —  Benefits paid (48.1) (61.6) (1.3) (0.7) Fair value of plan assets at end of year $ 515.4  $ 765.6  $ —  $ —  FUNDED STATUS $ (155.4) $ (172.1) $ (15.9) $ (18.9) Amounts recognized in the consolidated balance sheet consist of: Prepaid pensions (included in Other long-term assets) $ 6.8  $ 24.8  $ —  $ —  Accrued benefit liability (short-term and long-term) (162.2) (196.9) (15.9) (18.9) NET AMOUNT RECOGNIZED IN THE CONSOLIDATED BALANCE SHEET $ (155.4) $ (172.1) $ (15.9) $ (18.9) Amounts recognized in Accumulated other comprehensive loss (income) consist of: Net actuarial loss (gain) $ 244.4  $ 263.1  $ (5.5) $ (3.4) Prior service cost (credit) 6.3  6.9  —  —  NET AMOUNT RECOGNIZED IN ACCUMULATED OTHER COMPREHENSIVE LOSS $ 250.7  $ 270.0  $ (5.5) $ (3.4)   The accumulated benefit obligation for all defined benefit pension plans was $670.8 million and $937.7 million at December 31, 2022 and 2021, respectively. Information with respect to plans with accumulated benefit obligations in excess of plan assets is as follows, (in millions):   2022 2021 Projected benefit obligation $ 468.0  $ 817.7  Accumulated benefit obligation $ 468.0  $ 817.7  Fair value of plan assets $ 305.8  $ 620.7     The following table sets forth the components of pension and other benefit costs for the years ended December 31, (in millions):   Pension Benefits Other Benefits   2022 2021 2020 2022 2021 2020 Components of net periodic benefit cost:             Service cost $ 0.9  $ 1.0  $ 1.2  $ —  $ —  $ —  Interest cost 28.0  23.8  28.0  0.5  0.6  0.7  Expected return on plan assets (30.8) (36.5) (33.9) —  —  —  Amortization of prior service cost (credit) 0.4  0.2  0.2  —  —  (0.4) Amortization of actuarial losses (gains) 10.8  10.8  9.8  (0.2) (0.1) (0.1) Curtailment and settlement losses 8.8  —  7.5  —  —  —  Net periodic benefit cost $ 18.1  $ (0.7) $ 12.8  $ 0.3  $ 0.5  $ 0.2  Changes recognized in other comprehensive loss (income), before tax: Current year net actuarial loss (gain) $ 2.6  $ (1.4) $ 28.6  $ (2.2) $ (4.1) $ 0.1  Current year prior service credit —  3.6  —  —  —  —  Amortization of prior service (cost) credit (0.4) (0.2) (0.2) —  —  0.4  Amortization of net actuarial (losses) gains (10.8) (10.8) (9.8) 0.2  0.1  0.1  Currency impact (2.0) (0.2) 0.1  —  —  —  Settlement adjustment (8.8) —  (7.6) —  —  —  Curtailment adjustments —  —  0.1  —  —  —  Total recognized in other comprehensive loss (19.4) (9.0) 11.2  (2.0) (4.0) 0.6  TOTAL RECOGNIZED IN NET PERIODIC PENSION COST AND OTHER COMPREHENSIVE LOSS $ (1.3) $ (9.7) $ 24.0  $ (1.7) $ (3.5) $ 0.8    During 2022, the Company recognized $7.0 million of settlement losses in continuing operations and $1.8 million of settlement losses in discontinued operations. Those settlement losses are the result of lump-sum distributions from the Company's defined benefit pension plans which exceeded the threshold for settlement accounting under U.S. GAAP for the year. The Company also maintains four primary defined contribution pension plans. The total cost of the Company's defined contribution plans was $25.8 million in 2022, $23.3 million in 2021 and $21.0 million in 2020, excluding the employer match for the 401(k) plan. This cost is not included in the above net periodic benefit cost for the defined benefit pension plans.   In 2020, 2021 and 2022 the Company participated in one multi-employer defined benefit pension plan. The Company’s total contributions while participating in this plan was $0.2 million in each of these years. The risks of participating in multi-employer plans are different from single-employer plans in that assets contributed are pooled and may be used to provide benefits to employees of other participating employers. If a participating employer stops contributing to the plan, the unfunded obligations of the plan may have to be assumed by the remaining participant employers. If we choose to stop participating in a multi-employer plan we may be required to pay those plans a withdrawal liability based on the unfunded status of the plan. Assumptions   The following assumptions were used to determine the projected benefit obligations at the measurement date and the net periodic benefit cost for the year:   Pension Benefits Other Benefits   2022 2021 2020 2022 2021 2020 Weighted-average assumptions used to determine benefit obligations at December 31,           Discount rate 5.46  % 2.79  % 2.47  % 5.50  % 2.90  % 2.50  % Rate of compensation increase 0.08  % 0.08  % 0.24  % 3.93  % 3.87  % 3.99  % Weighted-average assumptions used to determine net periodic benefit cost for years ended December 31, Discount rate 2.79  % 2.47  % 3.17  % 2.90  % 2.50  % 3.30  % Expected return on plan assets 4.59  % 4.66  % 4.69  % N/A N/A N/A Rate of compensation increase 0.08  % 0.24  % 2.94  % 3.87  % 3.99  % 4.00  %   At the end of each year, the Company determines the appropriate expected return on assets for each plan based upon its strategic asset allocation (see discussion below). In making this determination, the Company utilizes expected returns for each asset class based upon current market conditions and expected risk premiums for each asset class.   The Company also determines the discount rate to be used to calculate the present value of pension plan liabilities at the end of each year. The discount rate for the Company’s U.S. and Canadian pension plans is determined by matching the expected cash flows associated with its benefit obligations to the expected cash flows of a hypothetical portfolio of high quality, fixed income debt instruments with maturities that closely match the expected funding period of its pension liabilities. As of December 31, 2022, the Company used a discount rate of 5.50% for its U.S. pension plans compared to a discount rate of 2.90% used in 2021. For its Canadian pension plan, the Company used a discount rate of 5.01% as of December 31, 2022 compared to a 2.98% discount rate used in 2021. For its UK pension plan the discount rate was derived using a full yield curve and uses plan specific cash flows. The derived discount rate is the single discount rate equivalent to discounting these liability cash flows at the term-dependent spot rate of AA corporate bonds. This methodology resulted in a December 31, 2022 discount rate for the UK pension plan of 5.00% as compared to a discount rate of 1.80% used in 2021. In 2020 we used the Pri-2012 mortality table to calculate the present value of our pension plan liabilities and adopted the MP-2020 projection scale, and in 2021 and 2022 we used the Pri-2012 mortality table and adopted the MP-2021 projection scale The Pri-2012 mortality table with adjustment for collar as appropriate and generational projection from 2012 using Scale MP-2021 was chosen as the best estimate based on the observed and anticipated experience of the plans after considering alternative tables. These changes did not have a material impact to the projected benefit obligation of our U.S. plans upon remeasurement.   The rate of compensation increase assumption reflects the Company’s actual experience and best estimate of future increases. The assumed health care cost trend rates used to determine the projected postretirement benefit obligation are as follows:    Other Benefits   2022 2021 2020 Assumed health care cost trend rates at December 31,       Health care cost trend assumed for next year 7.0  % 6.2  % 6.4  % Rate to which the cost trend is assumed to decline 5.0  % 5.0  % 5.0  % Year that the rate reaches the ultimate trend rate 2031 2028 2028   Plan Assets   The Company’s combined targeted 2023 weighted average asset allocation for domestic and foreign pension plans and the actual weighted average asset allocation for domestic and foreign pension plans at December 31, 2022 and 2021 by asset category are as follows:    Percentage of Plan Assets   Target Actual Asset Category 2023 2022 2021 Equity securities 32  % 23  % 22  % Debt securities & Cash 68  % 77  % 77  % Alternative Investments —  % —  % 1  % TOTAL 100  % 100  % 100  %   At the end of each year, the Company estimates the expected long-term rate of return on pension plan assets based on the strategic asset allocation for its plans. In making this determination, the Company utilizes expected rates of return for each asset class based upon current market conditions and expected risk premiums for each asset class. The Company has written investment policies and asset allocation guidelines for its domestic and foreign pension plans. In establishing these policies, the Company has considered that its various pension plans are a major retirement vehicle for most plan participants and has acted to discharge its fiduciary responsibilities with regard to the plans solely in the interest of such participants and their beneficiaries. The goal underlying the establishment of the investment policies is to provide that pension assets shall be invested in a prudent manner and so that, together with the expected contributions to the plans, the funds will be sufficient to meet the obligations of the plans as they become due.   To achieve this result, the Company conducts a periodic strategic asset allocation study to form a basis for the allocation of pension assets between various asset categories. Specific policy benchmark percentages are assigned to each asset category with minimum and maximum ranges established for each. The assets are then tactically managed within these ranges. Derivative investments include futures contracts used by the plan to adjust the level of its investments within an asset allocation category. The actual and target percentages reported in the preceding table reflect the economic exposure to each asset category, including the impact of derivative positions. All futures contracts are 100% supported by cash or cash equivalent investments. At no time may derivatives be utilized to leverage the asset portfolio. At December 31, 2022 and 2021, there were no holdings of Company stock in pension plan assets.   The Company’s other post-employment benefits are unfunded; therefore, no asset information is reported.   The fair value of the Company’s pension plan assets at December 31, 2022 and 2021, by asset category are as follows (in millions): Quoted Prices in Active Markets for Identical Assets Quoted Prices in Active Market for Similar Asset Significant Unobservable Inputs Investments Priced Using Net Asset Value Asset Category Total (Level 1) (Level 2) (Level 3) Cash and cash equivalents $ 9.8  $ 3.5  $ 6.3  $ —  $ —  Equity securities:      Equity Mutual Funds 21.5  21.5  —  —  —     Common Pooled Equity Funds (a) 84.5  —  84.5  —  —  Fixed Income Securities:      U.S. Treasuries 47.2  —  47.2  —  —     State and Local Municipal Bonds 6.4  —  6.4  —  —     Sovereign Debt 4.9  —  4.9  —  —     Corporate Bonds (b) 105.5  —  105.5  —  —     Fixed Income Mutual Funds 41.8  41.8  —  —  —     Common Pooled Fixed Income Funds (c) 174.2  —  148.7  —  25.5  Alternative Investment Funds (d) 2.1  —  —  —  2.1  Common Pooled Funds (e) 17.5  0.4  17.1  —  —  BALANCE AT DECEMBER 31, 2022 $ 515.4  $ 67.2  $ 420.6  $ —  $ 27.6    Quoted Prices in Active Markets for Identical Assets Quoted Prices in Active Market for Similar Asset Significant Unobservable Inputs Investments Priced Using Net Asset Value Asset Category Total (Level 1) (Level 2) (Level 3) Cash and cash equivalents $ 8.9  $ 8.9  $ —  $ —  $ —  Equity securities:      Equity Mutual Funds 31.7  31.7  —  —  —     Common Pooled Equity Funds (a) 123.3  —  123.3  —  —  Fixed Income Securities:      U.S. Treasuries 55.0  —  55.0  —  —     State and Local Municipal Bonds 6.2  —  6.2  —  —     Sovereign Debt 7.1  —  7.1  —  —     Corporate Bonds (b) 141.6  —  141.6  —  —     Fixed Income Mutual Funds 55.5  55.5  —  —  —     Common Pooled Fixed Income Funds (c) 306.3  —  275.2  —  31.1  Alternative Investment Funds (d) 7.1  —  —  —  7.1  Common Pooled Funds (e) 22.9  0.5  22.4  —  —  BALANCE AT DECEMBER 31, 2021 $ 765.6  $ 96.6  $ 630.8  $ —  $ 38.2  (a)Investments in Common Pooled Equity Funds, including funds and fund products investing in various equity securities.

The objective of these funds is to achieve the desired capital appreciation or fixed income as applicable with lower volatility than either traditional equity or fixed income securities. Contributions   In 2021, there were no contributions to the Company's U.S. qualified plans required by the Pension Protection Act of 2006. The Company contributed $10.0 million and $2.5 million to its U.S. and foreign qualified plans, respectively, in 2022. The Company entered into a settlement agreement with a multi-employer pension plan in December of 2019 and, pursuant to that agreement, made a $6.0 million cash payment in 2020, and $5.0 million cash payment in 2021, according to the terms of that settlement agreement. Estimated Future Benefit Payments   The following domestic and foreign benefit payments, which reflect future service, as appropriate, are expected to be paid as follows (in millions):  Pension Benefits Other Benefits 2023 $ 53.4  $ 1.7  2024 $ 53.6  $ 1.6  2025 $ 53.8  $ 1.6  2026 $ 53.9  $ 1.5  2027 $ 53.2  $ 1.4  2028-2031 $ 255.0  $ 6.0

Debt Disclosure [Abstract]
Debt	Debt   The following table sets forth the Company’s long-term debt at December 31, (in millions):   Maturity 2022 2021 Senior notes at 3.35% 2026 $ 397.9  $ 397.2  Senior notes at 3.15% 2027 297.5  297.0  Senior notes at 3.50% 2028 446.2  445.5  Senior notes at 2.300% 2031 296.3  295.8  TOTAL LONG-TERM DEBT(a)         $ 1,437.9  $ 1,435.5  (a) Long-term debt is presented net of debt issuance costs and unamortized discounts. On March 12, 2021, the Company, as borrower, and its subsidiaries Hubbell Power Holdings S.à r.l. and Harvey Hubbell Holdings S.à r.l., each as a subsidiary borrower (collectively, the “Subsidiary Borrowers”), entered into a new five-year credit agreement with a syndicate of lenders and JPMorgan Chase, N.A., as administrative agent, that provides a $750 million committed revolving credit facility (the "2021 Credit Facility"). Commitments under the 2021 Credit Facility may be increased to an aggregate amount not to exceed $1.25 billion. The 2021 Credit Facility includes a $50 million sub-limit for the issuance of letters of credit. The sum of the dollar amount of loans and letters of credits to the Subsidiary Borrowers under the 2021 Credit Facility may not exceed $75 million. The interest rate applicable to borrowings under the 2021 Credit Facility is either (i) the alternate base rate (as defined in the Revolving Credit Agreement) or (ii) the adjusted LIBOR rate (as defined in the 2021 Credit Facility) plus, in the case of this clause (ii), an applicable margin based on the Company’s credit ratings. All revolving loans outstanding under the 2021 Credit Facility will be due and payable on March 12, 2026. The 2021 Credit Facility contains a financial covenant requiring that, as of the last day of each fiscal quarter, the ratio of total indebtedness to total capitalization shall not be greater than 65%. The Company was in compliance with this covenant as of December 31, 2022. As of December 31, 2022 and December 31, 2021, the 2021 Credit Facility was undrawn. In connection with entry into the 2021 Credit Facility, the Company terminated all commitments under the existing credit facility dated as of January 31, 2018. On March 12, 2021, the Company completed a public offering of $300 million aggregate principal amount of its 2.300% Senior Notes due 2031 (the “2031 Notes”). The net proceeds from the offering were approximately $295.5 million after deducting the underwriting discount and estimated offering expenses payable by the Company. The Company used the net proceeds from the offering of the 2031 Notes, together with cash on hand, to redeem in full all of the Company’s outstanding 3.625% Senior Notes due 2022 in an aggregate principal amount of $300 million, which had a stated maturity date of November 15, 2022 (the “2022 Notes”), and to pay any premium and accrued interest in respect thereof, which redemption was completed on April 2, 2021. The redemption resulted in a $16.8 million loss on extinguishment of indebtedness that was recognized in the second quarter of 2021. The loss on extinguishment includes a cash premium of $16.0 million paid upon redemption in accordance with the terms of the 2022 Notes. The 2031 Notes bear interest at a rate of 2.300% per annum from March 12, 2021. Interest on the 2031 Notes is payable semi-annually in arrears on March 15 and September 15 of each year, beginning on September 15, 2021. The 2031 Notes will mature on March 15, 2031. The 2031 Notes are callable at any time with a make whole premium and are only subject to accelerated payment prior to maturity in the event of a default (including as a result of the Company's failure to meet certain non-financial covenants) under the indenture governing the notes or upon a change in control triggering event as defined in such indenture. The Company was in compliance with all non-financial covenants as of December 31, 2022. In February 2018, the Company completed a public offering of $450 million of senior, unsecured, notes maturing in February 2028 and bearing interest at a fixed rate of 3.50% (the "2028 Notes"). Net proceeds from the issuance of the 2028 Notes were $442.6 million after deducting the discount on such notes and offering expenses paid by the Company. The 2028 Notes are callable at any time at specified prices and are only subject to accelerated payment prior to maturity upon customary events of a default under the indenture governing the 2028 Notes, as modified by the supplemental indenture creating such notes, or upon a change in control triggering event as defined in such indenture. In August 2017, the Company completed a public debt offering of $300 million of long-term unsecured, unsubordinated notes maturing in August 2027 and bearing interest at a fixed rate of 3.15% (the "2027 Notes"). Net proceeds from the issuance were $294.6 million after deducting the discount on the notes and offering expenses paid by the Company. In March 2016, the Company completed a public debt offering of $400 million of long-term unsecured, unsubordinated notes maturing in March 2026 and bearing interest at a fixed rate of 3.35% (the "2026 Notes").

Income Taxes	12 Months Ended
	Dec. 31, 2022
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes   The following table sets forth selected data with respect to the Company’s income tax provisions of continuing operations for the years ended December 31, (in millions):    2022 2021 2020 Income before income taxes:       United States $ 528.9  $ 347.5  $ 340.7  International 128.1  111.8  83.8  TOTAL INCOME BEFORE INCOME TAXES $ 657.0  $ 459.3  $ 424.5  Provision for income taxes — current: Federal $ 120.3  $ 43.3  $ 56.3  State 24.2  13.0  15.1  International 23.5  22.7  17.0  Total provision — current 168.0  79.0  88.4  Provision for income taxes — deferred:   Federal (26.2) 8.8  1.5  State (3.9) 1.9  0.2  International 2.3  (1.5) (0.3) Total provision — deferred (27.8) 9.2  1.4  TOTAL PROVISION FOR INCOME TAXES $ 140.2  $ 88.2  $ 89.8    Deferred tax assets and liabilities result from differences in the basis of assets and liabilities for tax and financial statement purposes. The components of the deferred tax assets/(liabilities) of continuing operations at December 31, were as follows (in millions):   2022 2021 Deferred tax assets:     Inventories $ 9.6  $ 10.2  Lease liabilities 27.4  20.5  Income tax credits 22.8  22.8  Accrued liabilities 40.8  38.5  Pension 38.9  43.1  Basis difference in subsidiary —  25.1  Post retirement and post employment benefits 4.5  4.9  Stock-based compensation 6.9  6.7  Loss carryforwards 14.2  17.3  Capitalized research expenditures 18.4  —  Miscellaneous other 16.4  17.0  Gross deferred tax assets 199.9  206.1  Valuation allowance (32.2) (32.6) Total deferred tax assets, net of valuation allowance 167.7  173.5  Deferred tax liabilities:   Liability on undistributed foreign earnings (7.0) (7.9) Goodwill and intangibles (185.0) (205.2) Right-of-use assets (26.1) (19.5) Property, plant, and equipment (57.9) (50.4) Total deferred tax liabilities (276.0) (283.0) TOTAL NET DEFERRED TAX LIABILITY $ (108.3) $ (109.5) Deferred taxes are reflected in the Consolidated Balance Sheet as follows:   Non-current tax assets (included in Other long-term assets) $ 5.5  $ 5.2  Non-current tax liabilities (included in Other Non-Current Liabilities) (113.8) (114.7) TOTAL NET DEFERRED TAX LIABILITY $ (108.3) $ (109.5)   As of December 31, 2022, the Company had a total of $22.8 million of U.S. federal, state (net of federal benefit) and foreign tax credit carryforwards, available to offset future income taxes. As of December 31, 2022, $1.9 million of the tax credits may be carried forward indefinitely while the remaining $20.9 million will begin to expire at various times in 2023 through 2051. As of December 31, 2022, the Company had recorded tax benefits totaling $14.0 million for U.S. federal, state and foreign net operating loss carryforwards (“NOLs”). As of December 31, 2022, $5.5 million of NOLs may be carried forward indefinitely while the remaining $8.5 million will begin to expire at various times in 2023 through 2052. The tax benefit related to a portion of these NOLs has been adjusted to reflect an “ownership change” pursuant to Internal Revenue Code Section 382, which imposes an annual limitation on the utilization of pre-acquisition operating losses. The Company has recorded a net valuation allowance of $32.2 million on certain deferred tax assets including a portion of foreign and state tax credit carryforwards, capital loss carryforwards and NOLs that the Company anticipates will expire prior to utilization. During 2022, the Company repatriated certain of its foreign earnings. As of December 31, 2022, the Company also anticipates repatriating certain of its foreign earnings in the future. The accompanying financial statements reflect the income tax expense associated with actual and anticipated remittances related to certain of our outside basis differences. The Company has not provided for the income tax effects of distributing the remaining approximately $400 million of undistributed foreign earnings as those amounts are either permanently reinvested or intended to be reinvested in our international operations. It is not practicable to estimate the tax cost associated with a remittance of such earnings. Cash payments of income taxes were $168.0 million, $84.0 million and $96.2 million in 2022, 2021, and 2020, respectively. The Company operates within multiple taxing jurisdictions and is subject to audit in these jurisdictions. The IRS and other tax authorities routinely audit the Company’s tax returns. These audits can involve complex issues which may require an extended period of time to resolve. In January 2023 the Company completed its 2018 U.S. federal tax examination with no material adjustments. With few exceptions, the Company is no longer subject to state, local, or income tax examinations by tax authorities for years prior to 2018. The following tax years, by major jurisdiction, are still subject to examination by taxing authorities:  Jurisdiction Open Years United States 2019-2022 UK 2021-2022 Puerto Rico 2018-2022 Canada 2018-2022   A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in millions):    2022 2021 2020 Unrecognized tax benefits at beginning of year $ 41.2  $ 47.6  $ 41.9  Additions based on tax positions relating to the current year 12.1  6.1  7.4  Reductions based on expiration of statute of limitations (4.8) (10.3) (6.2) Additions/(Subtractions) to tax positions relating to previous years (6.2) (2.2) 4.5  Settlements (0.2) —  —  TOTAL UNRECOGNIZED TAX BENEFITS $ 42.1  $ 41.2  $ 47.6    Included in the balance at December 31, 2022 are approximately $33.9 million of tax positions which, if in the future are determined to be recognizable, would affect the annual effective income tax rate. Additionally, there are $4.3 million of tax positions for which the ultimate deductibility is highly certain but for which there is uncertainty as to the timing of such deductibility. Because of the impact of deferred tax accounting, other than interest and penalties, the disallowance of the shorter deductibility period would not affect the annual effective tax rate but would accelerate the payment of cash to the applicable taxing authority to an earlier period. It is reasonably possible that in the next twelve months, because of changes in facts and circumstances, the unrecognized tax benefits may increase or decrease. The Company estimates a possible decrease of approximately $5 million to $11 million within the next twelve months due to the expiration of the statute of limitations and audit resolutions.   The Company’s policy is to record interest and penalties associated with the underpayment of income taxes within Provision for income taxes in the Consolidated Statement of Income. The Company recognized (benefit) expense, before federal tax impact, related to interest and penalties of $(1.0) million in 2022, $0.3 million in 2021 and $0.2 million in 2020. The Company had $6.7 million and $7.6 million accrued for the payment of interest and penalties as of December 31, 2022 and December 31, 2021, respectively.   The consolidated effective income tax rate varied from the United States federal statutory income tax rate of continuing operations for the years ended December 31, as follows:   2022 2021 2020 Federal statutory income tax rate 21.0  % 21.0  % 21.0  % State income taxes, net of federal benefit 2.4  2.5  2.9  Foreign income taxes (0.2) (0.5) (0.2) Federal R&D Credit (0.8) (1.4) (1.3) Other, net (1.1) (2.4) (1.2) CONSOLIDATED EFFECTIVE INCOME TAX RATE 21.3  % 19.2  % 21.2  %   The foreign income tax benefit shown is primarily due to lower statutory rates in foreign jurisdictions compared to the United States federal statutory income tax rate.

Financial Instruments and Fair Value Measurement	12 Months Ended
	Dec. 31, 2022
Fair Value Disclosures [Abstract]
Financial Instruments and Fair Value Measurement	Financial Instruments and Fair Value Measurement   Financial Instruments Concentrations of Credit Risk: Financial instruments which potentially subject the Company to significant concentrations of credit risk consist of trade receivables, cash equivalents and investments. The Company grants credit terms in the normal course of business to its customers. Due to the diversity of its product lines, the Company has an extensive customer base including electrical distributors and wholesalers, electric utilities, equipment manufacturers, electrical contractors, telecommunication companies and retail and hardware outlets. We are not dependent on a single customer, however, the Company’s top ten customers account for approximately 43% of its Net sales. As part of its ongoing procedures, the Company monitors the credit worthiness of its customers. Bad debt write-offs have historically been minimal. The Company places its cash and cash equivalents with financial institutions and limits the amount of exposure in any one institution. At December 31, 2022 our accounts receivable balance was $741.6 million, net of allowances of $14.3 million. The allowance for doubtful accounts has not materially changed since December 31, 2021. Fair Value: The carrying amounts reported in the Consolidated Balance Sheet for cash and cash equivalents, short-term investments, receivables, bank borrowings, accounts payable and accruals approximate their fair values given the immediate or short-term nature of these items. See also Note 8 — Investments. Fair value measurements At December 31, 2022 and 2021 the Company had $80.2 million and $78.5 million respectively, of investments carried on the balance sheet at fair value. Fair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The FASB fair value measurement guidance established a fair value hierarchy that prioritizes the inputs used to measure fair value. Refer to Note 8 — Investments for more information about these investments. The three broad levels of the fair value hierarchy are as follows:   Level 1 -     Quoted prices (unadjusted) in active markets for identical assets or liabilities Level 2 -     Quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly Level 3 -     Unobservable inputs for which little or no market data exists, therefore requiring a company to develop its own assumptions The following tables show, by level within the fair value hierarchy, the Company’s financial assets and liabilities that are accounted for at fair value on a recurring basis at December 31, 2022 and 2021 (in millions): Asset (Liability) Quoted Prices in Active Markets for Identical Assets (Level 1) Quoted Prices in Active Markets for Similar Assets (Level 2) Unobservable inputs for which little or no market data exists (Level 3) Total Money market funds (a) $ 147.9  $ —  $ —  $ 147.9  Time Deposits (a) —  4.8  —  4.8  Available for sale investments —  61.4  —  61.4  Trading securities 18.8  —  —  18.8  Deferred compensation plan liabilities (18.8) —  —  (18.8) Derivatives: Forward exchange contracts-Assets (b) —  1.1  —  1.1  BALANCE AT DECEMBER 31, 2022 $ 147.9  $ 67.3  $ —  $ 215.2  Asset (Liability) Quoted Prices in Active Markets for Identical Assets (Level 1) Quoted Prices in Active Markets for Similar Assets (Level 2) Unobservable inputs for which little or no market data exists (Level 3) Total Money market funds (a) $ 58.5  $ —  $ —  $ 58.5  Available-for-sale investments —  54.0  —  54.0  Trading securities 24.5  —  —  24.5  Deferred compensation plan liabilities (24.5) —  —  (24.5) Derivatives:     Forward exchange contracts-Assets (b) —  0.5  —  0.5  BALANCE AT DECEMBER 31, 2021 $ 58.5  $ 54.5  $ —  $ 113.0  (a)Money market funds and time deposits are included in Cash and cash equivalents in the Consolidated Balance Sheet. (b)Forward exchange contracts-Assets are reflected in Other current assets in the Consolidated Balance Sheet. The methods and assumptions used to estimate the Level 2 fair values were as follows:   Forward exchange contracts – The fair value of forward exchange contracts were based on quoted forward foreign exchange prices at the reporting date. Available-for-sale municipal bonds classified in Level 2 – The fair value of available-for-sale investments in municipal bonds is based on observable market-based inputs, other than quoted prices in active markets for identical assets.  Deferred compensation plan The Company offers certain employees the opportunity to participate in non-qualified deferred compensation plans. A participant’s deferrals are invested in a variety of participant-directed debt and equity mutual funds that are classified as trading securities. During 2022 and 2021, the Company purchased $2.2 million and $2.7 million, respectively, of trading securities related to these deferred compensation plans. As a result of participant distributions, the Company sold $4.2 million and $3.6 million of these trading securities in 2022 and 2021 respectively. The unrealized gains and losses associated with these trading securities are directly offset by the changes in the fair value of the underlying deferred compensation plan obligation. Long-term Debt   As of December 31, 2022 and December 31, 2021, the carrying value of long-term debt, net of unamortized discount and debt issuance costs, was $1,437.9 million and $1,435.5 million, respectively. The estimated fair value of the long-term debt as of December 31, 2022 and December 31, 2021 was $1,306.5 million and $1,524.5 million, respectively, using quoted market prices in active markets for similar liabilities (Level 2).

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal and Environmental   The Company is subject to various legal proceedings arising in the normal course of its business. These proceedings include claims for damages arising out of use of the Company’s products, intellectual property, workers’ compensation and environmental matters. The Company is self-insured up to specified limits for certain types of claims, including product liability and workers’ compensation, and is fully self-insured for certain other types of claims, including environmental and intellectual property matters. The Company recognizes a liability for any contingency that in management’s judgment is probable of occurrence and can be reasonably estimated. We continually reassess the likelihood of adverse judgments and outcomes in these matters, as well as estimated ranges of possible losses based upon an analysis of each matter which includes advice of outside legal counsel and, if applicable, other experts. The Company is subject to environmental laws and regulations which may require that it investigate and remediate the effects of potential contamination associated with past and present operations as well as those acquired through business combinations. Environmental liabilities are recorded when remedial efforts are probable and the costs can be reasonably estimated. The Company continues to monitor these environmental matters and revalues its liabilities as necessary. Total environmental liabilities were $6.3 million and $6.4 million as of December 31, 2022 and 2021, respectively. The Company accounts for conditional asset retirement and environmental obligations in accordance with the applicable accounting guidance. The accounting guidance defines “conditional asset retirement obligation” as a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the Company. Accordingly, an entity is required to recognize a liability for the fair value of a conditional asset retirement obligation if the fair value of the liability can be reasonably estimated. Asset retirement obligations were not material as of December 31, 2022 and 2021.

Stock-Based Compensation	12 Months Ended
	Dec. 31, 2022
Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation   As of December 31, 2022, the Company had various stock-based awards outstanding which were issued to executives and other key employees. The Company recognizes the grant-date fair value of all stock-based awards to employees over their respective requisite service periods (generally equal to an award’s vesting period), net of estimated forfeitures. A stock-based award is considered vested for expense attribution purposes when the employee’s retention of the award is no longer contingent on providing subsequent service. For those awards that vest immediately upon retirement eligibility, the Company recognizes compensation cost immediately for retirement-eligible individuals or over the period from the grant date to the date retirement eligibility is achieved, if less than the stated vesting period.   The Company’s long-term incentive program for awarding stock-based compensation includes a combination of restricted stock, stock appreciation rights (“SARs”), and performance shares of the Company’s common stock pursuant to the Award Plan. Under the Award Plan, the Company may authorize up to 9.7 million shares of common stock to settle awards of restricted stock, performance shares, or SARs. The Company issues new shares to settle stock-based awards. In 2022, the Company's grant of stock-based awards included restricted stock, SARs and performance shares. Stock-based compensation expense recognized by the Company was $24.5 million in 2022, $17.5 million in 2021 and $21.9 million in 2020. The total income tax benefit recognized was $3.9 million in 2022, $3.2 million in 2021, and $3.2 million in 2020. The net tax windfall recorded as a result of exercise or vesting (depending on the type of award) was $3.2 million, $6.8 million, and $3.4 million in 2022, 2021 and 2020, respectively. As of December 31, 2022, there was $18.1 million, pretax, of total unrecognized compensation cost related to non-vested share-based compensation arrangements. This cost is expected to be primarily recognized through 2025. Stock-based compensation expense is recorded in S&A expense as well as Cost of goods sold. Of the total 2022 expense, $23.2 million was recorded to S&A expense and $1.3 million was recorded to Cost of goods sold. In 2021 and 2020, $15.8 million and $20.4 million, respectively, was recorded to S&A expense and $1.7 million and $1.5 million, respectively, was recorded to Cost of goods sold. Stock-based compensation costs capitalized to inventory was $0.4 million in each of 2022, 2021 and 2020. Each of the compensation arrangements is discussed below. Restricted Stock   The Company issues various types of restricted stock awards all of which are considered outstanding at the time of grant, as the award holders are entitled to dividends and voting rights. Unvested restricted stock awards are considered participating securities when computing earnings per share. Restricted stock grants are not transferable and are subject to forfeiture in the event of the recipient’s termination of employment prior to vesting. Restricted Stock Issued to Employees - Service Condition   Restricted stock awards that vest based upon a service condition are expensed on a straight-line basis over the requisite service period. These awards generally vest either in three equal installments on each of the first three anniversaries of the grant date or on the third year anniversary of the grant date. The fair value of these awards is measured by the average of the high and low trading prices of the Company’s common stock on the most recent trading day immediately preceding the grant date (“measurement date”). Restricted Stock Issued to Non-employee Directors   In 2022, 2021 and 2020, each non-employee director received a restricted stock grant. These grants are made on the date of the annual meeting of shareholders and vest at the following year’s annual meeting of shareholders, or upon certain other events. The grant is subject to forfeiture if the director’s service terminates prior to the date of the next regularly scheduled annual meeting of shareholders. During 2022, 2021 and 2020, the Company granted 5,952 shares, 6,741 shares, and 7,413 shares, respectively, to non-employee directors.   Restricted Stock Issued to Employees and Non-employee Directors Activity related to both employee and non-employee restricted stock for the year ended December 31, 2022 is as follows (in thousands, except per share amounts): Shares Weighted Average Grant Date Fair Value/Share RESTRICTED STOCK AT DECEMBER 31, 2021 184  $ 141.99  Shares granted 64  187.07  Shares vested (56) 148.93  Shares forfeited (13) 163.54  RESTRICTED STOCK AT DECEMBER 31, 2022 179  $ 154.09    The weighted average fair value per share of restricted stock granted in 2022, 2021 and 2020 was $187.07, $166.46 and $145.48, respectively. The total fair value of restricted stock vested in 2022, 2021 and 2020 was $8.4 million, $12.6 million and $7.8 million, respectively.   Stock Appreciation Rights SARs grant the holder the right to receive, once vested, the value in shares of the Company's common stock equal to the positive difference between the grant price, as determined using the mean of the high and low trading prices of the Company’s common stock on the measurement date, and the fair market value of the Company’s common stock on the date of exercise. This amount is payable in shares of the Company’s common stock. SARs vest and become exercisable in three equal installments during the first three years following the grant date and expire ten years from the grant date.   Activity related to SARs for the year ended December 31, 2022 is as follows (in thousands, except per share amounts): Number of Rights Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value OUTSTANDING AT DECEMBER 31, 2021 907  $ 132.78      Granted 143  186.62      Exercised (245) 122.49      Forfeited (26) 170.12      Canceled —  —  OUTSTANDING AT DECEMBER 31, 2022 779  $ 144.66  6.8 years $ 70,146  EXERCISABLE AT DECEMBER 31, 2022 452  $ 127.44  5.7 years $ 48,506    The aggregated intrinsic value of SARs exercised during 2022, 2021 and 2020 was $21.0 million, $46.8 million and $20.2 million, respectively.   The fair value of each SAR award was measured using the Black-Scholes option pricing model. The following table summarizes the weighted-average assumptions used in estimating the fair value of the SARs granted during the years 2022, 2021 and 2020: Grant Date Expected Dividend Yield Expected Volatility Risk Free Interest Rate Expected Term Weighted Avg. Grant Date Fair Value of 1 SAR 2022 2.1  % 27.4  % 1.9  % 4.9 years $ 39.68  2021 2.4  % 26.5  % 0.6  % 5.5 years $ 29.58  2020 2.5  % 23.5  % 1.3  % 5.5 years $ 24.52    The expected dividend yield was calculated by dividing the Company’s expected annual dividend by the average stock price for the past three months. Expected volatilities are based on historical volatilities of the Company’s stock for a period consistent with the expected term. The expected term of SARs granted was based upon historical exercise behavior of SARs. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the award.   Performance Shares Performance shares represent the right to receive a share of the Company’s common stock subject to the achievement of certain market or performance conditions established by the Company’s Compensation Committee and measured over a three year period. Partial vesting in these awards may occur after separation from the Company for retirement eligible employees. Shares are not vested until approved by the Company’s Compensation Committee. Performance Shares - Performance and Market Conditions In February 2020 and December 2018, the Company granted performance share awards with a target payout of 63,868 and 60,008 shares, respectively, that will vest subject to a performance condition and service requirement. The number of shares vested is then modified by a market condition as described below. Thirty-four percent of the award granted will vest based on Hubbell’s compounded annual growth rate of Net sales as compared to that of the companies that comprise the S&P Capital Goods 900 index. Thirty-three percent of the award granted will vest based on achieved operating margin performance as compared to internal targets, and thirty-three percent of the award granted will vest based on achieved trade working capital as a percent of Net sales as compared to internal targets. Each of these performance conditions is measured over the same three-year performance period. The cumulative result of these performance conditions can result in a number of shares earned in the range of 0% - 200% of the target number of shares subject to the award. That cumulative performance achieved is then further modified based on the Company's three year TSR relative to the companies that constitute the S&P Capital Goods 900 index, to potentially increase or reduce the shares earned by a multiple of up to 1.5 or 1.2, depending on the award year. The fair value of the award was determined based upon a lattice model. The Company expenses these awards on a straight-line basis over the requisite service period which includes an assessment of the performance achieved to date. The weighted average fair value per share was $151.78 for the awards granted in 2020 and $98.80 for the awards granted in 2018. Grant Date Shares Outstanding at 12/31/2022 Fair Value Performance Period Payout Range 2020 43,949 $ 151.78  Jan 2020-Dec 2022 0-200% + up to a multiple of 150x 2018 — $ 98.80  Jan 2019-Dec 2021 0-200% + up to a multiple of 120x During 2022, approximately 38,000 shares from the 2018 awards vested as a result of the cumulative achievement of the performance metrics, and the fair value of the awards at vesting was approximately $7.3 million. Performance Shares - Market Condition   In February 2022 and 2021, the Company granted performance share awards with a target payout of 14,076 and 15,741 shares, respectively, that will vest subject to a market condition and service condition through the performance period. The market condition associated with the awards is the Company's total shareholder return ("TSR") compared to the TSR generated by the companies that comprise the S&P Capital Goods 900 index over a three year performance period. Performance at target will result in vesting and issuance of the number of performance shares subject to the award, equal to 100% payout. Performance below or above target can result in issuance in the range of 0%-200% of the number of shares subject to the award. Expense is recognized irrespective of the market condition being achieved. The fair value of the performance share awards with a market condition for these grants was determined based upon a lattice model. The following table summarizes the related assumptions used to determine the fair values of the performance share awards with a market condition granted during February 2022 and 2021: Grant Date Stock Price on Measurement Date Dividend Yield Expected Volatility Risk Free Interest Rate Expected Term Weighted Avg. Grant Date Fair Value February 2022 $185.87 2.3% 39.7% 1.6% 2.9 years $221.94 February 2021 $163.26 2.4% 40.6% 0.2% 3 years $198.89 Expected volatilities are based on historical volatilities of the Company's and members of the peer group's stock over the expected term of the award. The risk free interest rate is based on the U.S. Treasury yield curve in effect at the time of the grant for the expected term of the award. Performance Shares - Performance Condition In February 2022 and 2021, the Company granted performance share awards with a target payout of 28,628 and 31,543 shares, respectively, that will vest subject to an internal Company-based performance condition and service requirement. Fifty percent of these performance shares subject to the award will vest based on Hubbell's compounded annual growth rate of Net sales as compared to that of the companies that comprise the S&P Capital Goods 900 index. Fifty percent of these performance shares subject to the award will vest based on achieved operating profit margin performance as compared to internal targets. Each of these performance conditions is measured over the same three-year performance period. The cumulative result of these performance conditions can result in a number of shares earned in the range of 0%-200% of the target number of shares subject to the award. The fair value of the award is measured based upon the average of the high and low trading prices of the Company's common stock on the measurement date reduced by the present value of dividends expected to be paid during the requisite service period. The Company expenses these awards on a straight-line basis over the requisite service period and including an assessment of the performance achieved to date. The weighted average fair value per share was $174.48 and $151.92 for the awards granted in 2022 and 2021, respectively. Grant Date Fair Value Performance Period Payout Range February 2022 $174.48 Jan 2022 - Dec 2024 0-200% February 2021 $151.92 Jan 2021 - Dec 2023 0-200%

Standard Product Warranty Disclosure [Abstract]
Guarantees	Guarantees   The Company records a liability equal to the fair value of guarantees in the Consolidated Balance Sheet in accordance with the accounting guidance for guarantees. When it is probable that a liability has been incurred and the amount can be reasonably estimated, the Company accrues for costs associated with guarantees. The most likely costs to be incurred are accrued based on an evaluation of currently available facts and, where no amount within a range of estimates is more likely, the minimum is accrued.   As of December 31, 2022, the fair value and maximum potential payment related to the Company’s guarantees were not material.   The Company offers product warranties which cover defects on most of its products. These warranties primarily apply to products that are properly installed, maintained and used for their intended purpose. The Company accrues estimated warranty costs at the time of sale. Estimated warranty expenses, recorded in cost of goods sold, are based upon historical information such as past experience, product failure rates, or the estimated number of units to be repaired or replaced. Adjustments are made to the product warranty accrual as claims are incurred, additional information becomes known or as historical experience indicates.   Changes in the accrual for product warranties in 2022 are set forth below (in millions): BALANCE AT DECEMBER 31, 2020 $ 72.7  Provision 8.8  Expenditures/other (15.4) BALANCE AT DECEMBER 31, 2021 $ 66.1  Provision 12.7  Expenditures/other (32.6) BALANCE AT DECEMBER 31, 2022(a) $ 46.2  (a) Refer to Note 10 – Other Accrued Liabilities and Note 11 – Other Non-Current Liabilities for a breakout of short-term and long-term warranties.

Restructuring and Related Activities [Abstract]
Restructuring Costs	Restructuring Costs During 2022, we incurred costs for restructuring actions initiated in 2022 as well as costs relating to restructuring actions initiated in the prior year. Our restructuring actions are associated with cost reduction efforts that include the consolidation of manufacturing and distribution facilities, as well as, workforce reductions and the sale or exit of business units we determine to be non-strategic. Restructuring costs are primarily severance and employee benefits, asset impairments, as well as facility closure, contract termination and certain pension costs that are directly related to restructuring actions. These costs are predominantly settled in cash from our operating activities and are generally settled within one year, with the exception of asset impairments, which are non-cash. Pre-tax restructuring costs incurred in each of our segments and the location of the costs in the Consolidated Statement of Income for the years ended December 31, 2022, 2021 and 2020 are as follows (in millions): Twelve Months Ended December 31, 2022 Twelve Months Ended December 31, 2021 Twelve Months Ended December 31, 2020 Utility Solutions Electrical Solutions Total Utility Solutions Electrical Solutions Total Utility Solutions Electrical Solutions Total Restructuring costs Cost of goods sold $ 4.5  $ 5.4  $ 9.9  $ 1.3  $ 1.1  $ 2.4  $ 9.2  $ 7.1  $ 16.3  S&A expense (0.5) 0.9  0.4  1.1  0.4  1.5  1.2  2.9  4.1  Total restructuring costs $ 4.0  $ 6.3  $ 10.3  $ 2.4  $ 1.5  $ 3.9  $ 10.4  $ 10.0  $ 20.4  The following table summarizes the accrued liabilities for our restructuring actions (in millions): Beginning Accrued  Restructuring Balance 1/1/22 Pre-tax Restructuring Costs Utilization and Foreign Exchange Ending Accrued  Restructuring Balance 12/31/22 2022 Restructuring Actions Severance $ —  $ 6.9  $ (1.3) $ 5.6  Asset write-downs —  0.8  (0.8) —  Facility closure and other costs —  3.5  (3.2) 0.3      Total 2022 Restructuring Actions $ —  $ 11.2  $ (5.3) $ 5.9  2021 and Prior Restructuring Actions Severance $ 4.1  $ (0.4) $ (1.8) $ 1.9  Asset write-downs —  —  —  —  Facility closure and other costs 0.1  (0.5) 0.5  0.1      Total 2021 and Prior Restructuring Actions $ 4.2  $ (0.9) $ (1.3) $ 2.0  Total Restructuring Actions $ 4.2  $ 10.3  $ (6.6) $ 7.9  The actual and expected pre-tax costs for our restructuring actions are as follows (in millions): Expected Costs Costs incurred in 2020 Costs incurred in 2021 Costs incurred in 2022 Remaining costs at 12/31/22 2022 Restructuring Actions Utility Solutions $ 5.0  $ —  $ —  $ 4.7  $ 0.3  Electrical Solutions 10.2  —  —  6.5  3.7      Total 2022 Restructuring Actions $ 15.2  $ —  $ —  $ 11.2  $ 4.0  2021 Restructuring Actions Utility Solutions $ 3.7  $ —  $ 1.8  $ (0.7) $ 2.6  Electrical Solutions 0.4  —  0.6  (0.2) —      Total 2021 Restructuring Actions $ 4.1  $ —  $ 2.4  $ (0.9) $ 2.6  2020 and Prior Restructuring Actions Utility Solutions $ 11.0  $ 10.4  $ 0.6  $ —  $ —  Electrical Solutions 10.9  10.0  0.9  —  —      Total 2020 and Prior Restructuring Actions $ 21.9  $ 20.4  $ 1.5  $ —  $ —  Total Restructuring Actions $ 41.2  $ 20.4  $ 3.9  $ 10.3  $ 6.6

Leases [Abstract]
Leases	Leases Our operating leases primarily consist of office space, certain manufacturing facilities, and vehicles. Our finance leases are not material. The term of our operating leases is generally 10 years or less, in some cases, with options to extend the term for up to 5 years, or options to terminate after one year without penalty. In general, our vehicle lease payments contain a monthly base rent payment which is adjusted based on changes to the LIBOR rate over the lease term. Certain other lease agreements contain variable payments related to a consumer price index or similar metric. Any change in payment amounts as a result of a change in a rate or index are considered variable lease payments and recognized as profit or loss when incurred. Rent expense for operating leases in the Consolidated Statements of Income for the years ended December 31, 2022, December 31, 2021, and December 31, 2020 were $35.7 million, $34.1 million, and $35.5 million, respectively. Cash paid for operating leases for the year ended December 31, 2022 and December 31, 2021 were $36.3 million and $36.7 million reported as cash outflows from operating activities in the Consolidated Statements of Cash Flows. Right-of-use ("ROU") assets obtained in exchange for lease obligations for the year ended December 31, 2022 and December 31, 2021 were $58.9 million and $17.8 million, respectively, which includes $7.4 million related to acquisitions in 2022.

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation   The accompanying consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). On February 1, 2022, the Company completed the sale of the Commercial and Industrial Lighting business (the "C&I Lighting business") to GE Current, a Daintree Company, for total net cash consideration of $332.8 million. The C&I Lighting business had sales of $509.4 million in 2021 as part of the Electrical Solutions segment and designs, manufactures, and sells LED lighting and control solutions for commercial and industrial customers. As a result of the agreement, the C&I Lighting business met the criteria set forth in ASC 205-20 to be presented as a discontinued operation. The C&I Lighting business' results of operations and the related cash flows have been presented as income from discontinued operations in the Consolidated Statements of Income and cash flows from discontinued operations in the Consolidated Statements of Cash Flows, respectively, for all periods presented.
Principles of Consolidation	Principles of Consolidation   The Consolidated Financial Statements include all wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated. The Company participates in two joint ventures that have been consolidated in accordance with the consolidation accounting guidance. An analysis is performed to determine which reporting entity, if any, has a controlling financial interest in a variable interest entity (“VIE”) with a primarily qualitative analysis. The qualitative analysis is based on identifying the party that has both the power to direct the activities that most significantly impact the VIE’s economic performance (the “power criterion”) and the obligation to absorb losses from or the right to receive benefits of the VIE that could potentially be significant to the VIE (the “losses/benefit criterion”). The party that meets both these criteria is deemed to have a controlling financial interest. The party with the controlling financial interest is considered to be the primary beneficiary and as a result is required to consolidate the VIE. The Company has a 50% interest in a joint venture in Hong Kong, established as Hubbell Asia Limited (“HAL”). The principal objective of HAL is to manage the operations of its wholly-owned manufacturing company in China. Under the accounting guidance, the Company is the primary beneficiary of HAL and as a result consolidates HAL. This determination is based on the fact that HAL’s sole business purpose is to manufacture product exclusively for the Company (the power criterion) and the Company is financially responsible for ensuring HAL maintains a fixed operating margin (the losses/benefit criterion). The consolidation of HAL is not material to the Company’s consolidated financial statements.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts in the Consolidated Financial Statements and accompanying Notes to Consolidated Financial Statements. Actual results could differ from the estimates that are used.
Impact of the COVID-19 Pandemic	Impact of the COVID-19 Pandemic During March 2020, a global pandemic was declared by the World Health Organization related to the rapidly growing outbreak of a novel strain of coronavirus (COVID-19). The pandemic has had, and may continue to have, a significant effect on global economic conditions. U.S. Federal, state, local, and foreign governments have reacted to the public health crisis with mitigation measures, creating significant uncertainties in the U.S. and global economies. The extent to which the coronavirus pandemic will continue to affect our business, operations, supply chains, and our financial results will depend on numerous evolving factors that we may not be able to accurately predict and which may cause the actual results to differ from the estimates and assumptions we are required to make in the preparation of financial statements according to GAAP.
Assets and Liabilities Held for Sale	Assets and Liabilities Held for Sale The Company classifies assets and liabilities (disposal groups) to be sold as held for sale in the period in which all of the following criteria are met: management, having the authority to approve the action, commits to a plan to sell the disposal group; the disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such disposal groups; an active program to locate a buyer and other actions required to complete the plan to sell the disposal group have been initiated; the sale of the disposal group is probable, and transfer of the disposal group is expected to qualify for recognition as a completed sale within one year, except if events or circumstances beyond the Company's control extend the period of time required to sell the disposal group beyond one year; the disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. The Company initially measures a disposal group that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a disposal group until the date of sale. The Company assesses the fair value of a disposal group, less any costs to sell, each reporting period it remains classified as held for sale and reports any subsequent changes as an adjustment to the carrying value of the disposal group, as long as the new carrying value does not exceed the carrying value of the disposal group at the time it was initially classified as held for sale.Upon determining that a disposal group meets the criteria to be classified as held for sale, the Company reports the assets and liabilities of the disposal group, if material, in the line items assets held for sale and liabilities held for sale in the consolidated statements of financial position.
Revenue Recognition	Revenue Recognition   The Company recognizes revenue when performance obligations identified under the terms of contracts with its customers are satisfied, which generally occurs, for products, upon the transfer of control in accordance with the contractual terms and conditions of the sale. The majority of the Company’s revenue associated with products is recognized at a point in time when the product is shipped to the customer, with a relatively small amount of transactions in the Utility Solutions segment recognized upon delivery of the product at the contractually specified destination. Revenue from service contracts and post-shipment performance obligations is approximately two percent of total annual consolidated net revenue and those service contracts and post-shipment obligations are primarily within the Utility Solutions segment. Revenue from service contracts and post-shipment performance obligations is recognized when or as those obligations are satisfied. The Company primarily offers assurance-type standard warranties that do not represent separate performance obligations and on occasion will separately offer and price extended warranties that are separate performance obligations for which the associated revenue is recognized over-time based on the extended warranty period. The Company records amounts billed to customers for reimbursement of shipping and handling costs within revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as fulfillment costs and are included in cost of goods sold. Sales taxes and other usage-based taxes are excluded from revenue. Within the Electrical Solutions segment, certain businesses require a portion of the transaction price to be paid in advance of transfer of control. Advance payments are not considered a significant financing component as they are received less than one year before the related performance obligations are satisfied. In addition, in the Utility Solutions segment, certain businesses offer annual maintenance service contracts that require payment at the beginning of the contract period. These payments are treated as a contract liability and are classified in Other accrued liabilities in the Consolidated Balance Sheet. Once control transfers to the customer and the Company meets the revenue recognition criteria, the deferred revenue is recognized in the Consolidated Statement of Income. The deferred revenue relating to the annual maintenance service contracts is recognized in the Consolidated Statement of Income on a straight line basis over the expected term of the contract. The Company has certain arrangements that require us to estimate at the time of sale the amounts of variable consideration that should not be recorded as revenue as certain amounts are not expected to be collected from customers, as well as an estimate of the value of the product to be returned. The Company principally relies on historical experience, specific customer agreements and anticipated future trends to estimate these amounts at the time of shipment and to reduce the transaction price. These arrangements include sales discounts and allowances based on sales volumes, specific programs and special pricing allowances, and returned goods, as are customary in the electrical products industry. Customer returns have historically been approximately 1% of gross sales. Shipping and Handling Costs   The Company records shipping and handling costs as part of Cost of goods sold in the Consolidated Statement of Income.
Foreign Currency Translation	Foreign Currency Translation   The assets and liabilities of international subsidiaries are translated to U.S. dollars at exchange rates in effect at the end of the year, and income and expense items are translated at average exchange rates in effect during the year. The effects of exchange rate fluctuations on the translated amounts of foreign currency assets and liabilities are included as translation adjustments in Accumulated other comprehensive loss within Hubbell shareholders’ equity. Gains and losses from foreign currency transactions are included in results of operations.
Cash and Cash Equivalents	Cash and Cash Equivalents   The carrying value of cash equivalents approximates fair value. Cash equivalents consist of highly liquid investments with original maturities to the Company of three months or less.
Investments	Investments   Investments in debt and equity securities are classified by individual security as available-for-sale, held-to-maturity or trading securities. Our available-for-sale securities, consisting of municipal bonds, are carried on the balance sheet at fair value with current period adjustments to carrying value recorded in Accumulated other comprehensive loss within Hubbell shareholders’ equity, net of tax. Realized gains and losses are recorded in income in the period of sale. The Company’s trading securities are carried on the balance sheet at fair value and consist primarily of debt and equity mutual funds. Gains and losses associated with these trading securities are reflected in the results of operations.
Accounts Receivable and Allowances	Accounts Receivable and Allowances   Trade accounts receivable are recorded at the invoiced amount and generally do not bear interest. The allowance for doubtful accounts is based on an estimated amount of probable credit losses in existing accounts receivable. The allowance is calculated based upon a combination of historical write-off experience, fixed percentages applied to aging categories and specific identification based upon a review of past due balances and problem accounts. Account balances are charged off against the allowance when it is determined that internal collection efforts should no longer be pursued. The Company also maintains a reserve for credit memos and cash discounts which are principally calculated based upon historical experience, specific customer agreements, as well as anticipated future trends.
Inventories	Inventories   Inventories are stated at the lower of cost or market value. Approximately 60% of total net inventory value is determined utilizing the last-in, first-out (LIFO) method of inventory accounting. The cost of foreign inventories and certain domestic inventories is determined utilizing average cost or first-in, first-out (FIFO) methods of inventory accounting. Reserves for excess and obsolete inventory are provided based on current assessments about future demand compared to on-hand quantities.
Property, Plant and Equipment	Property, Plant, and Equipment   Property, plant, and equipment values are stated at cost less accumulated depreciation. Maintenance and repair expenditures that do not significantly increase the life of an asset are charged to expense when incurred. Property, plant, and equipment placed in service prior to January 1, 1999 are depreciated over their estimated useful lives, principally, using accelerated methods. Assets placed in service subsequent to January 1, 1999 are depreciated over their estimated useful lives, using straight-line methods. Leasehold improvements are amortized over the shorter of their economic lives or the lease term. Gains and losses arising on the disposal of property, plant and equipment are included in Operating income in the Consolidated Statement of Income.
Capitalized Computer Software Costs	Capitalized Computer Software Costs   Capitalized computer software costs, net of amortization, were $7.0 million and $10.8 million at December 31, 2022 and 2021, respectively. This balance is reflected in Other long-term assets in the Consolidated Balance Sheet. Capitalized computer software is for internal use and costs primarily consist of purchased materials, external services and salary costs for personnel dedicated to the projects. Software is amortized on a straight-line basis over appropriate periods, generally between three and five years. The Company recorded amortization expense of $6.6 million in 2022, $9.6 million in 2021 and $10.0 million in 2020 relating to capitalized computer software.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets   Goodwill represents purchase price in excess of fair values of the underlying net assets of acquired companies. Indefinite-lived intangible assets and goodwill are subject to annual impairment testing using the specific guidance and criteria described in the accounting guidance. The Company performs its goodwill impairment testing as of April 1st of each year, unless circumstances dictate the need for more frequent assessments. The accounting guidance provides entities an option of performing a qualitative assessment (a "step-zero" test) before performing a quantitative analysis. If the entity determines, on the basis of certain qualitative factors, that it is more-likely-than-not that the goodwill is not impaired, the entity would not need to proceed to quantitative goodwill impairment testing process as prescribed in the guidance. The Company applied the "step-zero" test to one of its four reporting units. Based on that qualitative assessment, the Company concluded it was more-likely-than-not that the fair value of this reporting unit exceeded its carrying value and therefore, further quantitative analysis was not required. For the other three reporting units the Company has elected to utilize the quantitative goodwill impairment testing process as permitted in the accounting guidance, by comparing the estimated fair value of the Company's reporting units to their carrying values. If the fair value of the reporting unit exceeds its carrying value, no impairment exists.   Goodwill impairment testing requires judgment, including the identification of reporting units, assigning assets and liabilities to reporting units and determining the fair value of each reporting unit. Significant judgments required to estimate the fair value of reporting units include estimating future discounted cash flows, determining appropriate discount rates and other assumptions, including assumptions about secular economic and market conditions, such as the potential continuing effects of the COVID-19 pandemic, impacts to the supply chain and higher inflation. We use internal discounted cash flow models to estimate fair value. These cash flow estimates are derived from historical experience, third party end market data, and future long-term business plans and include assumptions on future sales growth, gross margin, operating margin, terminal growth rate, and the application of an appropriate discount rate. Changes in these estimates and assumptions could affect the determination of fair value and/or goodwill impairment for each reporting unit. The Company believes that its estimated aggregate fair value of its reporting units is reasonable when compared to the Company's market capitalization on the valuation date. On January 1, 2022, we internally reorganized certain businesses within our Electrical Solutions segment to simplify the organization structure and align the organization to better serve our customers. This change had no impact to our reportable segments. As a result of the change in reporting units, the Company performed an interim goodwill impairment assessment prior to the change, for the reporting units within the Electrical Solutions segment. Because the changes did not affect the Utility Solutions segment, no interim goodwill impairment assessment was required for that segment. As of April 1, 2022, the impairment testing resulted in implied fair values of our reporting units that exceeded the reporting unit's carrying value, including goodwill. The range of fair value in excess of carrying value, including goodwill, of the reporting units was 57% to 308%. Additionally, the Company did not have any reporting units with zero or negative carrying amounts. The Company has not recorded any goodwill impairments since the initial adoption of the accounting guidance in 2002. The Company’s intangible assets consist primarily of customer relationships, tradenames, developed technology and patents. Intangible assets with definite lives are amortized over periods generally ranging from 5-30 years. The Company amortizes intangible assets with definite lives using either an accelerated method that reflects the pattern in which economic benefits of the intangible assets are consumed and results in higher amortization in the earlier years of the assets' useful life, or using a straight line method. Approximately 80% of the gross value of definite-lived intangible assets follow an accelerated amortization method. These definite lived intangibles are tested for impairment whenever events or circumstances indicate that the carrying amount of an asset (asset group) may not be recoverable. An impairment loss is recognized when the carrying amount of an asset exceeds the estimated undiscounted cash flows used in determining the fair value of the asset. The Company did not record any material impairments related to its definite lived intangible assets in 2022, 2021 or 2020. The Company also has some tradenames that are considered to be indefinite-lived intangible assets. These indefinite-lived intangible assets are not amortized and are tested for impairment annually, unless circumstances dictate the need for more frequent assessment.   The identification and measurement of impairment of indefinite-lived intangible assets involves either an assessment of qualitative factors to determine whether events or circumstances indicate that it is more-likely-than-not that an indefinite-lived intangible asset is impaired or a quantitative assessment whereby the estimated fair value of each indefinite-lived intangible asset is compared to its carrying value. If it is more-likely-than-not that the asset is impaired, the fair value of the indefinite lived intangibles will be determined using discounted cash flow estimates. If the carrying value of these assets exceeds the estimated fair value, the carrying value will be reduced to the estimated fair value. For the Company’s annual impairment test as of April 1, 2022, the Company elected to utilize the quantitative impairment testing process as permitted in the accounting guidance. The fair value was determined utilizing an income approach (relief from royalty method). Significant judgment is required to estimate the fair value of the indefinite-lived intangible assets including assumptions for future revenues, discount rates, royalty rates, and other assumptions, including assumptions about secular economic and market conditions, such as the potential continuing effects of the COVID-19 pandemic. Significant changes in these estimates and assumptions could affect the determination of fair value and/or impairment for each indefinite-lived intangible asset. As of April 1, 2022, the impairment testing resulted in fair values for each indefinite-lived intangible asset that significantly exceeded the carrying values and there were no indefinite-lived intangible assets at risk of failing the quantitative impairment test. The Company did not record any impairments related to indefinite-lived intangible assets in 2022, 2021 and 2020.
Other Long-Lived Assets	Other Long-Lived Assets   The Company reviews depreciable long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. If such a change in circumstances occurs, the related estimated future undiscounted cash flows expected to result from the use of the asset group and its eventual disposition is compared to the carrying amount. If the sum of the expected cash flows is less than the carrying amount, an impairment charge is recorded. The impairment charge is measured as the amount by which the carrying amount exceeds the fair value of the asset. The fair value of impaired assets is determined using expected cash flow estimates, quoted market prices when available and appraisals as appropriate. The Company did not record any material impairment charges in 2022, 2021 or 2020.
Leases	Leases   We determine if an arrangement is a lease at inception. Operating leases are included as ROU assets within other long-term assets, other accrued liabilities, and other non-current liabilities in our Consolidated Balance Sheets. Finance leases are included in property, plant, and equipment, net, other accrued liabilities, and other non-current liabilities. The Company's finance leases are immaterial. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. We use an implicit rate when readily determinable. For leases existing as of January 1, 2019, we have elected to use the remaining lease term as of the adoption date in determining the incremental borrowing rate. Our determination of the lease term may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. We have lease agreements with lease and non-lease components, which are generally accounted for separately. Additionally, for our vehicle leases, we apply a portfolio approach regarding the assumed lease term.
Accrued Insurance	Accrued Insurance  The Company retains a significant portion of the risks associated with workers’ compensation, medical, automobile and general liability insurance. The Company estimates self-insurance liabilities using a number of factors, including historical claims experience, demographic factors, and other actuarial assumptions. The accrued liabilities associated with these programs are based on the Company’s estimate of the ultimate costs to settle known claims as well as claims incurred but not reported as of the balance sheet date. The Company periodically reviews the assumptions with a third party actuary to determine the adequacy of these self-insurance reserves.
Accrued Warranty	Accrued Warranty The Company offers product warranties which cover defects on most of its products. These warranties primarily apply to products that are properly installed, maintained and used for their intended purpose. The Company accrues estimated warranty costs at the time of sale. Estimated warranty expenses, recorded in cost of goods sold, are based upon historical information such as past experience, product failure rates, or the estimated number of units to be repaired or replaced. Adjustments are made to the product warranty accrual as claims are incurred, additional information becomes known or as historical experience indicates.
Income Taxes	Income Taxes   The Company operates within multiple taxing jurisdictions and is subject to audit in these jurisdictions. The IRS and other tax authorities routinely examine the Company’s tax returns. These audits can involve complex issues which may require an extended period of time to resolve. The Company makes adequate provisions for best estimates of exposures on previously filed tax returns. Deferred income taxes are recognized for the tax consequence of differences between financial statement carrying amounts and the tax basis of assets and liabilities by applying the currently enacted statutory tax rates in accordance with the accounting guidance for income taxes. The effect of a change in statutory tax rates is recognized in the period that includes the enactment date. Additionally, deferred tax assets are required to be reduced by a valuation allowance if it is more-likely-than-not that a portion or all of the deferred tax asset will not be realized. The Company uses factors to assess the likelihood of realization of deferred tax assets such as the forecast of future taxable income and available tax planning that could be implemented to realize the deferred tax assets.   In addition, the accounting guidance prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of the tax position taken or expected to be taken in a tax return. For any amount of benefit to be recognized, it must be determined that it is more-likely-than-not that a tax position will be sustained upon examination by taxing authorities based on the technical merits of the position. The amount of benefit to be recognized is based on the Company’s assertion of the most likely outcome resulting from an examination, including resolution of any related appeals or litigation processes. Companies are required to reflect only those tax positions that are more-likely-than-not to be sustained. See Note 14 — Income Taxes for additional information.
Research and Development	Research and Development   Research and development expenditures represent costs to discover and/or apply new knowledge in developing a new product, process, or in bringing about a significant improvement to an existing product or process. Research and development expenses are recorded as a component of Cost of goods sold.
Government Assistance	Government Assistance   We have adopted Accounting Standards Update ("ASU") 2021-10, Government Assistance (Topic 832) Disclosures by Business Entities about Government Assistance, which requires footnote disclosure of assistance received from government entities. We record amounts received from government entities as a reduction of the associated expense. Amounts received related to depreciable assets are recognized as a reduction to depreciation expense. The total impact of government assistance was not material to the Company in 2022, and prior periods presented.
Retirement Benefits	Retirement Benefits The Company maintains various defined benefit pension plans for some of its U.S. and foreign employees. The accounting guidance for retirement benefits requires the Company to recognize the funded status of its defined benefit pension and postretirement plans as an asset or liability in the Consolidated Balance Sheet. Gains or losses, prior service costs or credits, and transition assets or obligations that have not yet been included in net periodic benefit cost as of the end of the year are recognized as components of Accumulated other comprehensive loss, net of tax, within Hubbell shareholders’ equity. The Company’s policy is to fund pension costs within the ranges prescribed by applicable regulations. In addition to providing defined benefit pension benefits, the Company provides health care and life insurance benefits for some of its active and retired employees. The Company’s policy is to fund these benefits through insurance premiums or as actual expenditures are made. See also Note 12 — Retirement Benefits.
Earnings Per Share	Earnings Per Share   Restricted stock granted by the Company is considered a participating security since it contains a non-forfeitable right to dividends. As a result, the earnings per share accounting guidance requires the Company to use the two-class method for calculating earnings per share. The two-class method is an earnings allocation formula that determines earnings per share for common stock and participating securities. Basic earnings per share is calculated as net income available to common shareholders divided by the weighted average number of shares of common stock outstanding. Earnings per diluted share is calculated as net income available to common shareholders divided by the weighted average number of shares outstanding of common stock plus the incremental shares outstanding assuming the exercise of dilutive stock options, stock appreciation rights and performance shares. See also Note 19 — Earnings Per Share.
Stock-Based Compensation	Stock-Based Compensation   The Company recognizes the grant-date fair value of all stock-based awards on a straight-line basis over their respective requisite service periods (generally equal to an award’s vesting period). A stock-based award is considered vested for expense attribution purposes when the retention of the award is no longer contingent on providing subsequent service. Accordingly, the Company generally recognizes compensation cost immediately for awards granted to retirement-eligible individuals or over the period from the grant date to the date retirement eligibility is achieved, if less than the stated vesting period. The expense is recorded in Cost of goods sold and S&A expense in the Consolidated Statement of Income based on the recipients’ respective functions within the organization.   The Company records deferred tax assets for awards that will result in deductions on its tax returns, based upon the amount of compensation cost recognized and the statutory tax rate in the jurisdiction in which it will receive a deduction. See also Note 18 — Stock-Based Compensation.
Recent Accounting Pronouncements	Recently Issued Accounting Pronouncements In March 2020, the FASB issued ASU No. 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting", which provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments are effective for all entities beginning on March 12, 2020 through December 31, 2022. The Company may elect to apply the amendments prospectively through December 31, 2022. In December 2022, the FASB issued ASU No. 2022-06 Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which extends the temporary accounting rules under Topic 848 to December 31, 2024. The Company is currently assessing the impact of adopting this standard on its financial statements and the timing of adoption.
