1.Description of Business and Basis of Presentation

Description of Business

Orion Group Holdings, Inc. and subsidiaries (hereafter collectively referred to as the “Company”), is a leading specialty construction company serving the infrastructure, industrial, and building sectors, providing services both on and off the water in the continental United States, Alaska, Hawaii, Canada and the Caribbean Basin through our marine segment and our concrete segment. Our marine segment provides construction and dredging services including marine transportation facility construction, marine pipeline construction, marine environmental structures construction, dredging of waterways, channels and ports, environmental dredging, design, and specialty services related to marine construction, fabrication, and dredging. Our concrete segment provides turnkey concrete construction services including concrete surface place and finish, site preparation, layout, forming, and rebar placement for large commercial, structural and other associated business areas. We are headquartered in Houston, Texas with regional offices throughout our operating areas.

Although we describe the business in this report in terms of the services the Company provides, its base of customers and the areas in which it operates, the Company has determined that its operations currently comprise two reportable segments pursuant to Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 280, Segment Reporting.

The tools used by the chief operating decision maker (“CODM”) to allocate resources and assess performance are based on two reportable and operating segments: marine and concrete, which operate under the Orion brand and logo.

In making this determination, the Company considered the similar economic characteristics of its operations that comprise its marine segment. For the marine segment, the methods used, and the internal processes employed, to deliver marine construction services are similar throughout the segment, including standardized estimating, project controls and project management. This segment has the same customers with similar funding drivers and are subject to similar regulatory regimes driven through Federal agencies such as the U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, U.S. Environmental Protection Agency and U.S. Occupational Safety and Health Administration (“OSHA”), among others. Additionally, the segment is driven by macro-economic considerations including the level of import/export seaborne transportation, development of energy-related infrastructure, cruise line expansion and operations, marine bridge infrastructure development, waterway pipeline crossings and the maintenance of waterways. These considerations, and others, are key catalysts for future prospects and are similar across the segment.

For the concrete segment, the Company also considered the similar economic characteristics of these operations. The methods used, and the internal processes employed, to deliver concrete construction services are similar throughout the segment, including standardized estimating, project controls and project management. The projects of this segment are subject to similar regulatory regimes such as OSHA. Additionally, this segment is driven by macro-economic considerations, including movements in population, commercial real estate development, institutional funding and expansion, and recreational development,

specifically in metropolitan areas of Texas. These considerations, and others, are key catalysts for current operations and future prospects and are similar across the segment.

Basis of Presentation

The accompanying condensed consolidated financial statements and financial information included herein have been prepared pursuant to the interim period reporting requirements of Form 10-Q. Consequently, certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted. For the periods presented, there were no items of other comprehensive income, and therefore comprehensive loss is equal to net loss. Readers of this report should also read the Company’s consolidated financial statements, and the notes thereto included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (“2024 Form 10-K”) as well as Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations also included in its 2024 Form 10-K.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments considered necessary for a fair presentation of the Company’s financial position, results of operations, and cash flows for the periods presented. Such adjustments are of a normal recurring nature. Interim results of operations for the three months ended March 31, 2025 are not necessarily indicative of the results realizable for the year ending December 31, 2025.

In connection with preparing consolidated financial statements for each annual and interim reporting period, the Company is required to evaluate whether there are conditions or events, considered in aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within the one year period following the date that the financial statements are issued.

The assessment of the liquidity and going concern requires the Company to make estimates of future activity and judgments about whether the Company is compliant with financial covenant calculations under its debt and other agreements and has adequate liquidity to operate (See Note 9). Significant assumptions used in the Company's forecasted model of liquidity include forecasted sales, costs, our ability to manage spending on capital expenditures, our ability to complete certain asset sales and collect claims and unapproved change order revenue. Based on an assessment of these factors, management believes that the Company will have adequate liquidity for its operations for at least the next 12 months.

2.Summary of Significant Accounting Policies

The Company’s significant accounting policies are detailed in "Note 2. Summary of Significant Accounting Policies" of its 2024 Annual Report on Form 10-K.

Recent Accounting Pronouncements

The Financial Accounting Standards Board (“FASB”) issues accounting standards and updates (each, an “ASU”) from time to time to its Accounting Standards Codification (“ASC”), which is the primary source of U.S. GAAP. The Company regularly monitors ASUs as they are issued and considers applicability to its business. All ASUs are adopted by their respective due dates and in the manner prescribed by the FASB.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments require disclosure of specific categories in the rate reconciliation and

Table of Contents

provides additional information for reconciling items that meet a quantitative threshold and further disaggregation of income taxes paid for individually significant jurisdictions. The ASU is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. This will not impact our financial position or results of operations, but is expected to result in expanded tax disclosures in the full year financial statements for the year ended December 31, 2025.

In January 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures. The amendments require entities to provide enhanced disaggregation of certain expense categories presented in the income statement, including details on significant components within those categories, to provide greater transparency and decision-useful information to users of financial statements. The ASU is effective for fiscal years beginning after December 15, 2025, with early adoption permitted. The Company is currently evaluating the impact that this guidance will have on the disclosures within its consolidated financial statements.

3.Revenue

Contract revenues are recognized when control of the promised goods or services is transferred to the customer in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The following table represents a disaggregation of the Company’s contract revenues by service line for the marine and concrete segments:


	Three months ended March 31,
	2025		2024
Marine Segment
Construction	$	104,482	$	88,789
Dredging		16,911		14,670
Specialty services		5,770		2,866
Marine segment contract revenues	$	127,163	$	106,325

Concrete Segment
Structural	$	13,721	$	11,573
Light commercial		47,769		42,774
Concrete segment contract revenues	$	61,490	$	54,347

Total contract revenues	$	188,653	$	160,672

The Company has determined that it has two reportable segments pursuant to FASB ASC Topic 280, Segment Reporting, but has disaggregated its contract revenues in the above chart in terms of services provided within such segments. In making this determination, the Company considered the similar characteristics of its operations as discussed in Note 1. Additionally, as discussed, both the marine and concrete segments have limited contracts with multiple performance obligations. The Company’s contracts are often estimated and bid as one project and evaluated as to performance as one project, not by individual services performed by each. Both the marine and concrete segments have a single individual responsible for managing the entire segment, not by service lines of the segments. Resources are allocated by segment and financial and budgetary information is compiled and reviewed by segment, not service line.

Table of Contents

Marine Segment

Construction services include construction, restoration, maintenance, dredging and repair of marine transportation facilities, marine pipelines, bridges and causeways and marine environmental structures. Dredging services generally enhance or preserve the navigability of waterways or the protection of shorelines through the removal or replenishment of soil, sand or rock. Specialty services include design, salvage, demolition, surveying, towing, diving and underwater inspection, excavation and repair.

Concrete Segment

Structural services include elevated concrete pouring for products such as columns, elevated beams and structural walls. Light commercial services include horizontally poured concrete for products such as slabs, sidewalks, ramps and tilt walls. Other services comprise labor related to concrete pouring such as rebar installation and pumping services and typically support the Company’s structural and light commercial services.

4.Concentration of Risk and Enterprise-Wide Disclosures

In both reportable segments accounts receivable include amounts billed to governmental agencies and private customers and do not bear interest. Balances billed to customers but not paid pursuant to retainage provisions generally become payable upon contract completion and acceptance by the owner.

The table below presents the concentrations of current receivables (trade and retainage) at March 31, 2025 and December 31, 2024, respectively:


	March 31, 2025				December 31, 2024
Federal Government	$	43,336	24	%	$	19,874	14	%
State Governments		16,835	10	%		9,553	7	%
Local Governments		28,977	16	%		24,641	17	%
Private Companies		89,005	50	%		88,424	62	%
Gross receivables		178,153	100	%		142,492	100	%
Allowance for credit losses		(787)				(555)
Net receivables	$	177,366			$	141,937

At March 31, 2025, the United States Navy, which is included in the Federal Government category, accounted for 21.8% of total current receivables. At December 31, 2024, the United States Navy, accounted for 11.1% of total current receivables.

Table of Contents

Additionally, the table below represents concentrations of contract revenue by type of customer for the three months ended March 31, 2025 and 2024, respectively:


	Three months ended March 31,
	2025		%		2024		%
Federal Government	$	41,884	22	%	$	53,382	33	%
State Governments		28,961	15	%		13,984	9	%
Local Government		37,037	20	%		28,973	18	%
Private Companies		80,771	43	%		64,333	40	%
Total contract revenues	$	188,653	100	%	$	160,672	100	%

For the three months ended March 31, 2025, the United States Navy, which is included in the Federal Government category, accounted for 17.7% of total contract revenues. For the three months ended March 31, 2024, the United States Navy, which is included in the Federal Government category, accounted for 23.7% of total contract revenues.

With the exception of the Unites States Navy, the Company does not believe that the loss of any one of its customers would have a material adverse effect on the Company or its subsidiaries and affiliates since no single specific customer sustains such a large portion of receivables or contract revenue over time. On March 10, 2023, the United States Navy awarded the Dragados/Hawaiian Dredging/Orion Joint Venture a $2.8 billion contract to complete the construction of a dry dock at Pearl Harbor Naval Shipyard. The Company’s portion of work as a dedicated subcontractor totals $454.5 million. For the three months ended March 31, 2025 and 2024, the Company’s revenue related to the joint venture subcontract was approximately $33.3 million and $38.0 million, respectively

The concrete segment primarily purchases concrete from select suppliers. The loss of any one of these suppliers could adversely impact short-term operations.

Contract revenues generated outside the United States totaled 6.3% and 6.0% of total revenues for the three months ended March 31, 2025 and 2024, respectively, and were primarily located in the Caribbean Basin.

5.Contracts in Progress

Contracts in progress are as follows at March 31, 2025 and December 31, 2024:


	March 31,		December 31,
	2025		2024
Costs incurred on uncompleted contracts	$	1,509,260	$	1,561,338
Estimated earnings		204,590		211,439
		1,713,850		1,772,777
Less: Billings to date		(1,693,026)		(1,735,741)
	$	20,824	$	37,036
Included in the accompanying Consolidated Balance Sheets under the following captions:
Contract assets	$	63,580	$	84,407
Contract liabilities		(42,756)		(47,371)
	$	20,824	$	37,036

Table of Contents

Included in contract assets is approximately $17.1 million and $19.8 million at March 31, 2025 and December 31, 2024, respectively, related to claims and unapproved change orders. See Note 2 to the Company’s consolidated financial statements for discussion of the accounting for these claims.

Remaining performance obligations represent the transaction price of firm orders or other written contractual commitments from customers for which work has not been performed or is partially completed and excludes unexercised contract options and potential orders. As of March 31, 2025, the aggregate amount of the remaining performance obligations was approximately $839.7 million. Of this amount, the current expectation of the Company is that it will recognize $644.7 million, or 77%, in the next 12 months and the remaining balance thereafter.

6.Property and Equipment

The following is a summary of property and equipment at March 31, 2025 and December 31, 2024:

7.Fair Value

Recurring Fair Value Measurements

The fair value of financial instruments is the amount at which the instrument could be exchanged in a current transaction between willing parties. Due to their short-term nature, the Company believes that the carrying value of its accounts receivable, other current assets, accounts payable and other current liabilities approximate their fair values.

Table of Contents

The Company classifies financial assets and liabilities into the following three levels based on the inputs used to measure fair value in the order of priority indicated:

●

Level 1- fair values are based on observable inputs such as quoted prices in active markets for identical assets or liabilities;

●

Level 2 - fair values are based on pricing inputs other than quoted prices in active markets for identical assets and liabilities and are either directly or indirectly observable as of the measurement date; and

●

Level 3 - fair values are based on unobservable inputs in which little or no market data exists.

Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value requires judgment and may affect the placement of assets and liabilities within the fair value hierarchy levels.

The following table sets forth by level within the fair value hierarchy the Company’s recurring financial assets and liabilities that were accounted for at fair value on a recurring basis as of March 31, 2025 and December 31, 2024:


			Fair Value Measurements
	Carrying Value		Level 1	Level 2	Level 3
March 31, 2025
Assets:
Cash surrender value of life insurance policy	$	1,203	—	1,203	—
December 31, 2024
Assets:
Cash surrender value of life insurance policy	$	1,222	—	1,222	—

Our concrete segment has life insurance policies with a combined face value of $11.1 million as of March 31, 2025. The policies are invested in mutual funds and the fair value measurement of the cash surrender balance associated with these policies is determined using Level 2 inputs within the fair value hierarchy and will vary with investment performance. These assets are included in the "Other non-current" asset section in the Company’s Condensed Consolidated Balance Sheets.

Other Fair Value Measurements

The fair value of the Company’s debt at March 31, 2025 and December 31, 2024 approximated its carrying value of $26.7 million and $26.8 million, respectively, as interest is based on current market interest rates for debt with similar risk and maturity. If the Company’s debt was measured at fair value, it would have been classified as Level 2 in the fair value hierarchy.

9.Debt

On May 15, 2023, the Company entered into a Credit Agreement (the “Credit Agreement”) with White Oak ABL, LLC and White Oak Commercial Finance, LLC, providing for a $65.0 million asset-based revolving credit facility (the “Revolver”) and a $38.0 million fixed asset term loan (the “Term Loan”). The Credit Agreement, as subsequently amended, matures on May 15, 2028 and is secured by substantially all of the assets of the Company and its subsidiaries, including fixed assets and accounts receivable.

The Credit Agreement is used to finance working capital and general corporate purposes, capital expenditures, permitted acquisitions and associated transaction fees, and to refinance existing indebtedness. Borrowings under the Revolver may be repaid and reborrowed, subject to the borrowing base and other conditions.

As amended, the Revolver and Term Loan bear interest at rates based on 30-day SOFR plus applicable margins, subject to a SOFR floor. As of the date of this filing, the applicable margin is 4.25% for the Revolver and 6.50% for the Term Loan, with a 4.00% SOFR floor.

The Credit Agreement contains customary affirmative and negative covenants, including limitations on indebtedness, liens, investments, asset sales, and dividends, as well as financial maintenance covenants. The financial covenants, as amended, include a minimum Consolidated Fixed Charge Coverage Ratio and/or Consolidated EBITDA thresholds and a minimum liquidity requirement, each tested periodically.

The quarterly weighted average interest rate for the Credit Agreement, as of March 31, 2025 and March 31, 2024 was 11.25% and 13.09%, respectively.

In addition, the Credit Agreement contains events of default that are usual and customary for similar arrangements, including non-payment of principal, interest or fees; breaches of representations and warranties that are not timely cured; violation of covenants; bankruptcy and insolvency events; and, events constituting a change of control.

The Company was in compliance with all financial covenants under the amended agreement as of March 31, 2025.

Other debt

The Company has entered into debt agreements with Mobilease for the purpose of financing equipment purchased. As of March 31, 2025 and December 31, 2024, the carrying value of this debt was $1.3 million and $1.4 million, respectively. The agreements are secured by the financed equipment assets and the debt is included as a component of current debt and long-term debt on the Condensed Consolidated Balance Sheets.

On June 23, 2023, the Company closed on a land-sale leaseback contract for the Company’s Port Lavaca South Yard property located in Port Lavaca, Texas for a purchase price of $12.0 million.

Sale-Leaseback Arrangements

On May 15, 2023, the Company entered into a $13.0 million sale-leaseback of certain equipment in which the Company leased-back the equipment for terms ranging from one to three years. The transaction above was recorded as a failed sale-leaseback.

Concurrent with the sale of Company’s Port Lavaca South Yard property, the Company entered into a twenty-year lease agreement whereby the Company will lease back the property at an annual rental rate of approximately $1.1 million, subject to annual rent increases of 2.5%. Under the lease agreement, the Company

Table of Contents

has four consecutive options to extend the term of the lease by five years for each such option. The portion of the above transaction related to the building was recorded as a failed sale-leaseback.

On September 27, 2019, the Company entered into a purchase and sale agreement (the “Purchase and Sale Agreement”). Pursuant to the terms of the Purchase and Sale Agreement, the Company sold its 17300 and 17140 Market Street location in Channelview, Texas for a purchase price of $19.1 million. Concurrent with the sale of the property, the Company entered into a fifteen-year lease agreement whereby the Company will lease back the property at an annual rental rate of approximately $1.5 million, subject to annual rent increases of 2.0%. Under the lease agreement, the Company has two consecutive options to extend the term of the lease by ten years for each such option. The transaction above was recorded as a failed sale-leaseback.

Related to the failed sale-leasebacks, the Company recorded liabilities for the amounts received, will continue to depreciate the non-land portion of the assets, and has imputed an interest rate so that the net carrying amount of the financial liability and remaining assets will be zero at the end of the initial lease terms.

11.Income Taxes

Income tax expense (benefit) included in the Company’s accompanying Condensed Consolidated Statements of Operations was as follows (in thousands, except percentages):


	Three months ended
	March 31,
		2025			2024
Income tax expense (benefit)	$	140		$	(352)
Effective tax rate		(11.0)	%		5.5	%

The effective rate for the three months ended March 31, 2025 differed from the Company’s statutory federal rate of 21% primarily due to the tax impact from the valuation allowance for current year activity, state income taxes and the non-deductibility of other permanent items.

The Company's effective tax rate is typically based on expected income for the calendar year, statutory rates and tax planning opportunities available. This estimated annual effective tax rate is then applied to year-to-date operations. A small change in the year-to-date operations could result in a large change to the estimated annual effective tax rate. Therefore, the Company’s effective tax rate for the period ending March 31, 2025, is based off actual year-to-date operations.

The Company assessed the realizability of its deferred tax assets and determined that it was more likely than not that some portion or all the deferred tax assets would not be realized and therefore recorded a valuation allowance on the net deferred tax assets. The Company assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. The Company considers the scheduled reversal of deferred tax liabilities, available carryback periods, and tax-planning strategies in making this assessment. For the period ended March 31, 2025 the Company evaluated all positive and negative evidence in determining the amount of deferred tax assets more likely than not to be realized. Based on the review of available evidence, management believes that a valuation allowance on the net deferred tax assets at March 31, 2025 remains appropriate.

12.Earnings Per Share

Basic earnings per share is based on the weighted average number of common shares outstanding during each period. Diluted earnings per share is based on the weighted average number of common shares outstanding as well as the effect of all dilutive common stock equivalents during each period net income is generated. For the three months ended March 31, 2025 and 2024, the Company had 55,302 and 222,075 securities, respectively, that were potentially dilutive in earnings per share calculations. Such dilution is dependent on the excess of the market price of our stock over the exercise price and other components of the treasury stock method. The exercise price for certain stock options awarded by the Company exceeded the average market price of the Company’s common stock for the three months ended March 31, 2025 and 2024. Such stock options are antidilutive and are not included in the computation of earnings per share for those periods. The Company reported a net loss for the three months ended March 31, 2025 and March 31, 2024; therefore, all potentially dilutive securities are antidilutive and are excluded from the computation of diluted loss per share for such periods.

The following table reconciles the denominators used in the computations of both basic and diluted earnings per share:


	Three months ended March 31,
	2025	2024
Basic:
Weighted average shares outstanding	39,056,396	32,553,750

13.Share-Based Compensation

The Compensation Committee of the Company’s Board of Directors is responsible for the administration of the Company’s stock incentive plans, which include the balance of shares remaining under the 2022 Long Term Incentive Plan (the “2022 LTIP”), which was approved by shareholders in May of 2022 and amended in May of 2024 and authorizes 3,735,000 shares, the maximum aggregate number to be issued, plus any shares available for grant under prior long term incentive plans as of the date the 2022 LTIP was approved, and any shares subject to awards granted under the prior plans that expire or are cancelled, forfeited, exchanged, settled in cash or otherwise terminated. In general, the Company’s 2022 LTIP provides for grants of restricted stock and performance-based awards to be issued with a per-share price not less than the fair market value of a share of common stock on the date of grant. The Company accounts for forfeitures of awards as they are incurred.

In May 2024 shareholders approved the ESPP, which became effective on September 16, 2024. The Company has reserved a total of 1,000,000 shares under the ESPP, all of which are authorized and available for future issuance under the ESPP. The ESPP provides a means by which eligible employees of the Company are given an opportunity to purchase shares of common stock at a discount as permitted under the Internal Revenue Code of 1986, as amended. During the three months ended March 31, 2025, there were 71,133 shares issued under the ESPP generating proceeds to the Company of $0.3 million. The Company has an outstanding liability

A maximum of 1.6 million common shares could be awarded based upon the Company’s achievement of set performance-metrics.

On March 20, 2025, the Company granted certain executives a total of 293,073 performance-based units. The performance-based units will potentially vest 100% if the target is met, with 50% of the units to be earned based on the achievement of an absolute adjusted EBITDA target, measured over a three-year performance period and 50% of the units to be earned based on the achievement of an objective, tiered return on relative total shareholder return, measured over a three-year performance period. The Company evaluates the probability of achieving this each reporting period. The fair value of the grants awarded related to the adjusted EBITDA target was $5.89 per share and the fair value of the grants awarded related to the relative total shareholder return was $8.45 valued using a Monte Carlo simulation model.

The following table presents the assumptions related to the performance share units granted in 2025 related to the relative total shareholder return, as indicated in the previous summary table:


		2025
Grant-date fair value	$	5.89
Risk-free interest rate		3.86	%
Volatility factor		65.52	%
Contractual term (years)		2.78

ITEM 2.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

Unless the context otherwise indicates, all references in this Quarterly Report on Form 10-Q to “Orion,” “the Company,” “we,” “our,” or “us” are to Orion Group Holdings, Inc. and its subsidiaries as a whole.

Certain information in this Quarterly Report on Form 10-Q, including but not limited to Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”), may constitute forward-looking statements as such term is defined within the meaning of the “safe harbor” provisions of Section 27A of the Securities Act of 1933, as amended and Section 21E of the Securities Exchange Act of 1934, as amended.

All statements other than statements of historical facts, including those that express a belief, expectation, or intention are forward-looking statements. The forward-looking statements may include projections and estimates concerning the timing and success of specific projects and our future production, our pipeline of opportunities, conversion of backlog, revenues, income and capital spending. Our forward-looking statements are generally accompanied by words such as “estimate,” “project,” “predict,” “believe,” “expect,” “anticipate,” “potential,” “plan,” “goal” or other words that convey the uncertainty of future events or outcomes.

We have based these forward-looking statements on our current expectations and assumptions about future events. While our management considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which are difficult to predict and many of which are beyond our control, including unforeseen productivity delays and other difficulties encountered in project execution, challenges incurred by virtue of our position as a substantial subcontractor that reports to a significantly larger project contractor, levels of government funding or other governmental budgetary constraints, contract modifications and changes, including change orders and contract cancellation at the discretion of the customer, and the general economic impact of tariffs and trade wars. These and other important factors, including those described under “Risk Factors” in Part 1, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2024 may cause our actual results, performance- or achievements to differ materially from any future results, performance or achievements expressed or implied by these forward-looking statements. The forward-looking statements in this Quarterly Report on Form 10-Q speak only as of the date of this report; we disclaim any obligation to update these statements unless required by securities law, and we caution you not to rely on them unduly.

MD&A provides a narrative analysis explaining the reasons for material changes in the Company’s (i) financial condition since the most recent fiscal year-end, and (ii) results of operations during the current fiscal year-to-date period and current fiscal quarter as compared to the corresponding periods of the preceding fiscal year. In order to better understand such changes, this MD&A should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in our 2024 Form 10-K, Part II, Item 7 Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our 2024 Form 10-K and with our unaudited condensed consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q.

Overview

Orion Group Holdings, Inc. and subsidiaries (hereafter collectively referred to as the “Company”), is a leading specialty construction company serving the infrastructure, industrial, and building sectors, providing services both on and off the water in the continental United States, Alaska, Hawaii, Canada and the Caribbean Basin through our marine segment and our concrete segment. Our marine segment provides construction and dredging services, including marine transportation facility construction, marine pipeline construction, marine environmental structures construction, dredging of waterways, channels and ports, environmental dredging, design, and specialty services related to marine construction, fabrication, and dredging. Our concrete segment provides turnkey concrete construction services, including concrete surface place and finish, site preparation, layout, forming, and rebar placement for large commercial, structural and other associated business areas. We are headquartered in Houston, Texas with regional offices throughout our operating areas.

Our contracts are obtained primarily through competitive bidding in response to “requests for proposals” by federal, state and local agencies and through negotiation and competitive bidding with private parties and general contractors. Our bidding activity and strategies are affected by factors such as our backlog, current utilization of equipment and other resources, job location, our ability to obtain necessary surety bonds and competitive considerations. The timing and location of awarded contracts may result in unpredictable fluctuations in the results of our operations.

Most of our revenue is derived from fixed-price contracts. We record revenue on construction contracts over time, measured by the percentage of actual contract costs incurred to date to total estimated costs for each contract. There are a number of factors that can create variability in contract performance and therefore impact the results of our operations. The most significant of these include the following:

●

completeness and accuracy of the original bid;

●

increases in commodity prices such as concrete, steel and fuel;

●

customer delays, work stoppages, and other costs due to weather and environmental restrictions;

●

subcontractor performance;

●

unforeseen site conditions;

●

availability and skill level of workers; and

●

a change in availability and proximity of equipment and materials.

All of these factors can have a negative impact on our contract performance, which can adversely affect the timing of revenue recognition and ultimate contract profitability. We plan our operations and bidding activity with these factors in mind and they generally have not had a material adverse impact on the results of our operations in the past.

Consolidated Results of Operations

Backlog Information

Our contract backlog represents our estimate of the revenues we expect to realize under the portion of contracts remaining to be performed. Given the typical duration of our contracts, which is generally less than a year, our backlog at any point in time usually represents only a portion of the revenue that we expect to realize during a

Table of Contents

twelve-month period. We have not been adversely affected by contract cancellations or modifications in the past, however we may be in the future, especially in periods of economic uncertainty.

Backlog as of the periods ended below are as follows (in millions):


	March 31, 2025		December 31, 2024		September 30, 2024		June 30, 2024		March 31, 2024
Marine segment	$	607.4	$	582.8	$	537.0	$	567.1	$	569.9
Concrete segment		232.3		146.3		153.5		191.3		186.7
Consolidated	$	839.7	$	729.1	$	690.5	$	758.4	$	756.6

We are optimistic in our end-markets and in the opportunities that are emerging across our various marketplaces as evidenced by the $1.3 billion of quoted bids outstanding at quarter end, of which over $51 million were awarded but not fully contracted as of or awarded subsequent to March 31, 2025.

These estimates are subject to fluctuations based upon the scope of services to be provided, as well as factors affecting the time required to complete the project. Backlog is not necessarily indicative of future results. In addition to our backlog under contract, we also have a substantial number of projects in negotiation or pending award at any given time. Delays in decisions on pending awards also have a negative impact on the timing and amount by which we are able to increase backlog.

Contract Revenues. Contract revenues for the three months ended March 31, 2025 of $188.7 million increased $28.0 million or 17.4% as compared to $160.7 million in the prior year period. The increase was primarily due to an increase in revenue from large marine construction contracts and new concrete projects.

Gross Profit. Gross profit was $23.0 million for the three months ended March 31, 2025 compared to $15.5 million in the prior year period, an increase of $7.5 million, or 48.1%. Gross profit in the quarter was 12.2% of total contract revenues as compared to 9.7% in the prior year period. The increases in gross profit dollars and

Table of Contents

margin were primarily driven by an improvement in indirect expenses in the marine segment as a result of a higher volume of work, partially offset by lower margins in the concrete segment which were primarily driven by normal seasonally lower productivity.

Selling, General and Administrative Expense. Selling, general and administrative (“SG&A”) expenses were $22.5 million for the three months ended March 31, 2025 compared to $19.0 million in the prior year period, an increase of $3.5 million or 18.7%. As a percentage of total contract revenues, SG&A expenses increased to 12.0% from 11.8%. The increases in SG&A dollars and percentage reflect an increase in compensation expense and operating lease expense.

Gain on Disposal of Assets, net. During the three months ended March 31, 2025 and 2024 we realized $0.4 million and $0.3 million, respectively, of net gains on disposal of assets.

Other Income, net of Expense. Other expense primarily reflects interest on our borrowings, partially offset by interest income and non-operating gains or losses.

Income Tax Expense (Benefit). We recorded tax expense of $0.1 million in the three months ended March 31, 2025, compared to tax benefit of $0.4 million in the prior year period. We expect near break-even operations for the full year ended December 31, 2025, such that a small change in the year-to-date operations could result in a large change to the estimated annual effective tax rate. Therefore, our effective tax rate for the period ending March 31, 2025, is based off actual year-to-date operations.

Marine Segment

Revenues for our marine segment for the three months ended March 31, 2025 were $127.2 million compared to $106.3 million for the three months ended March 31, 2024, an increase of $20.9 million, or 19.6%. The increase was primarily due to an increase in revenue from large marine construction contracts.

Operating income for our marine segment for the three months ended March 31, 2025 was $4.8 million, compared to operating loss of $4.9 million for the three months ended March 31, 2024, an increase of $9.7 million. The increase in operating income was primarily related to an improvement in indirect expenses and more disciplined execution and bidding standards to exclude lower margin contracts.

Concrete Segment

Revenues for our concrete segment for the three months ended March 31, 2025 were $61.5 million compared to $54.3 million for the three months ended March 31, 2024, an increase of $7.2 million, or 13.1%. This increase was primarily due to new projects.

Operating loss for our concrete segment for the three months ended March 31, 2025 was $3.9 million, compared to operating income of $1.7 million for the three months ended March 31, 2024, a decrease of $5.6 million. This decrease was primarily driven by lower margins which were primarily driven by normal seasonally lower productivity.

Liquidity and Capital Resources

Changes in working capital are normal within our business given the varying mix in size, scope, seasonality and timing of delivery of our projects. At March 31, 2025, our working capital was $73.4 million, as compared to $78.2 million at December 31, 2024. As of March 31, 2025, we had unrestricted cash on hand of $13.0 million. Our borrowing availability under our revolving portion of our Credit Agreement at March 31, 2025 was approximately $40.7 million.

Our primary liquidity needs are to finance our working capital and fund capital expenditures. Historically, our sources of liquidity have been cash provided by our operating activities, sale of underutilized assets, and borrowings under our credit facilities. The assessment of our liquidity requires us to make estimates of future activity and judgments about whether we are compliant with financial covenant calculations under our debt and other agreements and have adequate liquidity to operate. Significant assumptions used in our forecasted model of liquidity include forecasted sales, costs, and capital expenditures, as well as expected timing and proceeds of planned real estate transactions. As of March 31, 2025, management believes the Company will have adequate liquidity for its operations for at least the next 12 months.

Cash flows used in financing activities	$	(3,225)	$	(1,902)

Capital expenditures (included in investing activities above)	$	(9,033)	$	(1,853)

Operating Activities. During the three months ended March 31, 2025 we used approximately $3.4 million of cash in our operating activities. The net cash outflow was comprised of $11.3 million of outflows related to changes in net working capital, partially offset by $7.9 million of cash inflows from net income, after adjusting for non-cash items. The changes in net working capital, which are reflected as changes in operating assets and liabilities in our Condensed Consolidated Statements of Cash Flows, were primarily driven by a $27.7 million cash outflow related to a decrease in our net position of accounts receivable and accounts payable plus accrued liabilities during the period and a $1.2 million decrease in operating lease liabilities, partially offset by $16.2 million of cash inflows pursuant to the relative timing and significance of project progression and billings during the period, a $1.3 million inflow related to a decrease in prepaid expenses and other, and $0.1 million of other inflows.

Investing Activities. During the three months ended March 31, 2025, we used approximately $8.7 million of cash in our investing activities. Capital asset additions and betterments to our fleet were $9.0 million and $1.9 million in the three months ended March 31, 2025 and 2024, respectively. Proceeds from the sale of property and equipment were $0.3 million in both the three months ended March 31, 2025 and March 31, 2024.

Financing Activities. During the three months ended March 31, 2025, we used approximately $3.2 million of cash in our financing activities. During the three months ended March 31, 2025, we had borrowings and repayments of $3.0 million on the White Oak revolving credit line, payments on finance lease liabilities of $2.5 million, payments made on failed sale-leaseback arrangements of $0.7 million, loan costs of $0.3 million and repayments of $0.1 million on other debt, partially offset by inflows of $0.3 million from proceeds from issuance of common stock under the employee stock purchase plan and $0.1 million from proceeds from stock option exercises.

Sources of Capital

On May 15, 2023, we entered into a new three-year $103.0 million Credit Agreement with White Oak which includes a $65.0 million asset based revolving credit line and a $38.0 million fixed asset term loan. Please see “Note 9 – Debt” in our unaudited condensed consolidated financial statements for a more detailed description of the Credit Facility.

Table of Contents

We were in compliance with all financial covenants under the amended agreement as of March 31, 2025.

Bonding Capacity

We are often required to provide various types of surety bonds that provide additional security to our customers for our performance under certain government and private sector contracts. Our ability to obtain surety bonds depends on our capitalization, working capital, past performance and external factors, including the capacity of the overall surety market. At March 31, 2025, the capacity under our current bonding arrangement was at least $1.1 billion, with approximately $535 million of projects being bonded. While we believe that our current bonding capacity is sufficient to satisfy current demand for our services, any new major project opportunities may require us to seek additional bonding capacity in the future. We believe our balance sheet and working capital position will allow us to access additional bonding capacity as needed in the future.

Effect of Inflation

We are subject to the effects of inflation through increases in the cost of raw materials, and other items such as fuel, concrete and steel. Due to the relative short-term duration of our projects, we are generally able to include anticipated cost increases in the pricing of our bids.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

In the normal course of business, our results of operations are subject to risks related to fluctuations in commodity prices and fluctuations in interest rates. Historically, our exposure to foreign currency fluctuations has not been material and has been limited to temporary field accounts located in foreign countries where we perform work. Foreign currency fluctuations were immaterial in this reporting period.

Commodity price risk

We are subject to fluctuations in commodity prices for concrete, steel products and fuel. Although we routinely attempt to secure firm quotes from our suppliers, we generally do not hedge against increases in prices for commodity products. Commodity price risks may have an impact on our results of operations due to the fixed-price nature of many of our contracts, although the short-term duration of our projects may allow us to include cost increases to the pricing of our bids.

Interest rate risk

At March 31, 2025, we had $23.0 million in outstanding borrowings under our Credit Agreement, with a weighted average ending interest rate of 10.94%. Based on the amounts outstanding under our Credit Agreement as of March 31, 2025, a 100 basis-point increase in SOFR (or an equivalent successor rate) would increase the Company’s annual interest expense by approximately $0.2 million.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As required, the Company’s management, with the participation of its Chief Executive Officer and Chief Financial Officer, have conducted an evaluation of the effectiveness of the Company’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective as of March 31, 2025.

Table of Contents

Changes in Internal Control over Financial Reporting

During the quarter ended March 31, 2025, we implemented new reporting systems and made changes to related internal controls. There have been no other changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended March 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Description of Business and Basis of Presentation
1.Description of Business and Basis of Presentation
Description of Business
Orion Group Holdings, Inc. and subsidiaries (hereafter collectively referred to as the “Company”), is a leading specialty construction company serving the infrastructure, industrial, and building sectors, providing services both on and off the water in the continental United States, Alaska, Hawaii, Canada and the Caribbean Basin through our marine segment and our concrete segment. Our marine segment provides construction and dredging services including marine transportation facility construction, marine pipeline construction, marine environmental structures construction, dredging of waterways, channels and ports, environmental dredging, design, and specialty services related to marine construction, fabrication, and dredging. Our concrete segment provides turnkey concrete construction services including concrete surface place and finish, site preparation, layout, forming, and rebar placement for large commercial, structural and other associated business areas. We are headquartered in Houston, Texas with regional offices throughout our operating areas.
Although we describe the business in this report in terms of the services the Company provides, its base of customers and the areas in which it operates, the Company has determined that its operations currently comprise two reportable segments pursuant to Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 280, Segment Reporting.
The tools used by the chief operating decision maker (“CODM”) to allocate resources and assess performance are based on two reportable and operating segments: marine and concrete, which operate under the Orion brand and logo.
In making this determination, the Company considered the similar economic characteristics of its operations that comprise its marine segment. For the marine segment, the methods used, and the internal processes employed, to deliver marine construction services are similar throughout the segment, including standardized estimating, project controls and project management. This segment has the same customers with similar funding drivers and are subject to similar regulatory regimes driven through Federal agencies such as the U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, U.S. Environmental Protection Agency and U.S. Occupational Safety and Health Administration (“OSHA”), among others. Additionally, the segment is driven by macro-economic considerations including the level of import/export seaborne transportation, development of energy-related infrastructure, cruise line expansion and operations, marine bridge infrastructure development, waterway pipeline crossings and the maintenance of waterways. These considerations, and others, are key catalysts for future prospects and are similar across the segment.
For the concrete segment, the Company also considered the similar economic characteristics of these operations. The methods used, and the internal processes employed, to deliver concrete construction services are similar throughout the segment, including standardized estimating, project controls and project management. The projects of this segment are subject to similar regulatory regimes such as OSHA. Additionally, this segment is driven by macro-economic considerations, including movements in population, commercial real estate development, institutional funding and expansion, and recreational development,
specifically in metropolitan areas of Texas. These considerations, and others, are key catalysts for current operations and future prospects and are similar across the segment.
Basis of Presentation
The accompanying condensed consolidated financial statements and financial information included herein have been prepared pursuant to the interim period reporting requirements of Form 10-Q. Consequently, certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted. For the periods presented, there were no items of other comprehensive income, and therefore comprehensive loss is equal to net loss. Readers of this report should also read the Company’s consolidated financial statements, and the notes thereto included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (“2024 Form 10-K”) as well as Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations also included in its 2024 Form 10-K.
In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments considered necessary for a fair presentation of the Company’s financial position, results of operations, and cash flows for the periods presented. Such adjustments are of a normal recurring nature. Interim results of operations for the three months ended March 31, 2025 are not necessarily indicative of the results realizable for the year ending December 31, 2025.
In connection with preparing consolidated financial statements for each annual and interim reporting period, the Company is required to evaluate whether there are conditions or events, considered in aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within the one year period following the date that the financial statements are issued.
The assessment of the liquidity and going concern requires the Company to make estimates of future activity and judgments about whether the Company is compliant with financial covenant calculations under its debt and other agreements and has adequate liquidity to operate (See Note 9). Significant assumptions used in the Company's forecasted model of liquidity include forecasted sales, costs, our ability to manage spending on capital expenditures, our ability to complete certain asset sales and collect claims and unapproved change order revenue. Based on an assessment of these factors, management believes that the Company will have adequate liquidity for its operations for at least the next 12 months.

Accounting Policies [Abstract]

Summary of Significant Accounting Principles
2.Summary of Significant Accounting Policies
The Company’s significant accounting policies are detailed in "Note 2. Summary of Significant Accounting Policies" of its 2024 Annual Report on Form 10-K.
Recent Accounting Pronouncements
The Financial Accounting Standards Board (“FASB”) issues accounting standards and updates (each, an “ASU”) from time to time to its Accounting Standards Codification (“ASC”), which is the primary source of U.S. GAAP. The Company regularly monitors ASUs as they are issued and considers applicability to its business. All ASUs are adopted by their respective due dates and in the manner prescribed by the FASB.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments require disclosure of specific categories in the rate reconciliation and
provides additional information for reconciling items that meet a quantitative threshold and further disaggregation of income taxes paid for individually significant jurisdictions. The ASU is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. This will not impact our financial position or results of operations, but is expected to result in expanded tax disclosures in the full year financial statements for the year ended December 31, 2025.
In January 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures. The amendments require entities to provide enhanced disaggregation of certain expense categories presented in the income statement, including details on significant components within those categories, to provide greater transparency and decision-useful information to users of financial statements. The ASU is effective for fiscal years beginning after December 15, 2025, with early adoption permitted. The Company is currently evaluating the impact that this guidance will have on the disclosures within its consolidated financial statements.

Contract revenues are recognized when control of the promised goods or services is transferred to the customer in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The following table represents a disaggregation of the Company’s contract revenues by service line for the marine and concrete segments:

The Company has determined that it has two reportable segments pursuant to FASB ASC Topic 280, Segment Reporting, but has disaggregated its contract revenues in the above chart in terms of services provided within such segments. In making this determination, the Company considered the similar characteristics of its operations as discussed in Note 1. Additionally, as discussed, both the marine and concrete segments have limited contracts with multiple performance obligations. The Company’s contracts are often estimated and bid as one project and evaluated as to performance as one project, not by individual services performed by each. Both the marine and concrete segments have a single individual responsible for managing the entire segment, not by service lines of the segments. Resources are allocated by segment and financial and budgetary information is compiled and reviewed by segment, not service line.
Marine Segment
Construction services include construction, restoration, maintenance, dredging and repair of marine transportation facilities, marine pipelines, bridges and causeways and marine environmental structures. Dredging services generally enhance or preserve the navigability of waterways or the protection of shorelines through the removal or replenishment of soil, sand or rock. Specialty services include design, salvage, demolition, surveying, towing, diving and underwater inspection, excavation and repair.
Concrete Segment
Structural services include elevated concrete pouring for products such as columns, elevated beams and structural walls. Light commercial services include horizontally poured concrete for products such as slabs, sidewalks, ramps and tilt walls. Other services comprise labor related to concrete pouring such as rebar installation and pumping services and typically support the Company’s structural and light commercial services.

For the three months ended March 31, 2025, the United States Navy, which is included in the Federal Government category, accounted for 17.7% of total contract revenues. For the three months ended March 31, 2024, the United States Navy, which is included in the Federal Government category, accounted for 23.7% of total contract revenues.
With the exception of the Unites States Navy, the Company does not believe that the loss of any one of its customers would have a material adverse effect on the Company or its subsidiaries and affiliates since no single specific customer sustains such a large portion of receivables or contract revenue over time. On March 10, 2023, the United States Navy awarded the Dragados/Hawaiian Dredging/Orion Joint Venture a $2.8 billion contract to complete the construction of a dry dock at Pearl Harbor Naval Shipyard. The Company’s portion of work as a dedicated subcontractor totals $454.5 million. For the three months ended March 31, 2025 and 2024, the Company’s revenue related to the joint venture subcontract was approximately $33.3 million and $38.0 million, respectively
The concrete segment primarily purchases concrete from select suppliers. The loss of any one of these suppliers could adversely impact short-term operations.
Contract revenues generated outside the United States totaled 6.3% and 6.0% of total revenues for the three months ended March 31, 2025 and 2024, respectively, and were primarily located in the Caribbean Basin.

Remaining performance obligations represent the transaction price of firm orders or other written contractual commitments from customers for which work has not been performed or is partially completed and excludes unexercised contract options and potential orders. As of March 31, 2025, the aggregate amount of the remaining performance obligations was approximately $839.7 million. Of this amount, the current expectation of the Company is that it will recognize $644.7 million, or 77%, in the next 12 months and the remaining balance thereafter.

Fair Value Disclosures [Abstract]

Fair Value
7.Fair Value
Recurring Fair Value Measurements
The fair value of financial instruments is the amount at which the instrument could be exchanged in a current transaction between willing parties. Due to their short-term nature, the Company believes that the carrying value of its accounts receivable, other current assets, accounts payable and other current liabilities approximate their fair values.
The Company classifies financial assets and liabilities into the following three levels based on the inputs used to measure fair value in the order of priority indicated:
● Level 1- fair values are based on observable inputs such as quoted prices in active markets for identical assets or liabilities;
● Level 2 - fair values are based on pricing inputs other than quoted prices in active markets for identical assets and liabilities and are either directly or indirectly observable as of the measurement date; and
● Level 3 - fair values are based on unobservable inputs in which little or no market data exists.
Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value requires judgment and may affect the placement of assets and liabilities within the fair value hierarchy levels.
The following table sets forth by level within the fair value hierarchy the Company’s recurring financial assets and liabilities that were accounted for at fair value on a recurring basis as of March 31, 2025 and December 31, 2024:

Our concrete segment has life insurance policies with a combined face value of $11.1 million as of March 31, 2025. The policies are invested in mutual funds and the fair value measurement of the cash surrender balance associated with these policies is determined using Level 2 inputs within the fair value hierarchy and will vary with investment performance. These assets are included in the "Other non-current" asset section in the Company’s Condensed Consolidated Balance Sheets.
Other Fair Value Measurements
The fair value of the Company’s debt at March 31, 2025 and December 31, 2024 approximated its carrying value of $26.7 million and $26.8 million, respectively, as interest is based on current market interest rates for debt with similar risk and maturity. If the Company’s debt was measured at fair value, it would have been classified as Level 2 in the fair value hierarchy.

Debt
9.Debt
On May 15, 2023, the Company entered into a Credit Agreement (the “Credit Agreement”) with White Oak ABL, LLC and White Oak Commercial Finance, LLC, providing for a $65.0 million asset-based revolving credit facility (the “Revolver”) and a $38.0 million fixed asset term loan (the “Term Loan”). The Credit Agreement, as subsequently amended, matures on May 15, 2028 and is secured by substantially all of the assets of the Company and its subsidiaries, including fixed assets and accounts receivable.
The Credit Agreement is used to finance working capital and general corporate purposes, capital expenditures, permitted acquisitions and associated transaction fees, and to refinance existing indebtedness. Borrowings under the Revolver may be repaid and reborrowed, subject to the borrowing base and other conditions.
As amended, the Revolver and Term Loan bear interest at rates based on 30-day SOFR plus applicable margins, subject to a SOFR floor. As of the date of this filing, the applicable margin is 4.25% for the Revolver and 6.50% for the Term Loan, with a 4.00% SOFR floor.
The Credit Agreement contains customary affirmative and negative covenants, including limitations on indebtedness, liens, investments, asset sales, and dividends, as well as financial maintenance covenants. The financial covenants, as amended, include a minimum Consolidated Fixed Charge Coverage Ratio and/or Consolidated EBITDA thresholds and a minimum liquidity requirement, each tested periodically.
The quarterly weighted average interest rate for the Credit Agreement, as of March 31, 2025 and March 31, 2024 was 11.25% and 13.09%, respectively.

Sale-Leaseback Arrangements
On May 15, 2023, the Company entered into a $13.0 million sale-leaseback of certain equipment in which the Company leased-back the equipment for terms ranging from one to three years. The transaction above was recorded as a failed sale-leaseback.
Concurrent with the sale of Company’s Port Lavaca South Yard property, the Company entered into a twenty-year lease agreement whereby the Company will lease back the property at an annual rental rate of approximately $1.1 million, subject to annual rent increases of 2.5%. Under the lease agreement, the Company
has four consecutive options to extend the term of the lease by five years for each such option. The portion of the above transaction related to the building was recorded as a failed sale-leaseback.
On September 27, 2019, the Company entered into a purchase and sale agreement (the “Purchase and Sale Agreement”). Pursuant to the terms of the Purchase and Sale Agreement, the Company sold its 17300 and 17140 Market Street location in Channelview, Texas for a purchase price of $19.1 million. Concurrent with the sale of the property, the Company entered into a fifteen-year lease agreement whereby the Company will lease back the property at an annual rental rate of approximately $1.5 million, subject to annual rent increases of 2.0%. Under the lease agreement, the Company has two consecutive options to extend the term of the lease by ten years for each such option. The transaction above was recorded as a failed sale-leaseback.
Related to the failed sale-leasebacks, the Company recorded liabilities for the amounts received, will continue to depreciate the non-land portion of the assets, and has imputed an interest rate so that the net carrying amount of the financial liability and remaining assets will be zero at the end of the initial lease terms.

Effective tax rate

(11.0)
%

%

The effective rate for the three months ended March 31, 2025 differed from the Company’s statutory federal rate of 21% primarily due to the tax impact from the valuation allowance for current year activity, state income taxes and the non-deductibility of other permanent items.
The Company's effective tax rate is typically based on expected income for the calendar year, statutory rates and tax planning opportunities available. This estimated annual effective tax rate is then applied to year-to-date operations. A small change in the year-to-date operations could result in a large change to the estimated annual effective tax rate. Therefore, the Company’s effective tax rate for the period ending March 31, 2025, is based off actual year-to-date operations.
The Company assessed the realizability of its deferred tax assets and determined that it was more likely than not that some portion or all the deferred tax assets would not be realized and therefore recorded a valuation allowance on the net deferred tax assets. The Company assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. The Company considers the scheduled reversal of deferred tax liabilities, available carryback periods, and tax-planning strategies in making this assessment. For the period ended March 31, 2025 the Company evaluated all positive and negative evidence in determining the amount of deferred tax assets more likely than not to be realized. Based on the review of available evidence, management believes that a valuation allowance on the net deferred tax assets at March 31, 2025 remains appropriate.

Earnings Per Share [Abstract]

Earnings Per Share
12.Earnings Per Share
Basic earnings per share is based on the weighted average number of common shares outstanding during each period. Diluted earnings per share is based on the weighted average number of common shares outstanding as well as the effect of all dilutive common stock equivalents during each period net income is generated. For the three months ended March 31, 2025 and 2024, the Company had 55,302 and 222,075 securities, respectively, that were potentially dilutive in earnings per share calculations. Such dilution is dependent on the excess of the market price of our stock over the exercise price and other components of the treasury stock method. The exercise price for certain stock options awarded by the Company exceeded the average market price of the Company’s common stock for the three months ended March 31, 2025 and 2024. Such stock options are antidilutive and are not included in the computation of earnings per share for those periods. The Company reported a net loss for the three months ended March 31, 2025 and March 31, 2024; therefore, all potentially dilutive securities are antidilutive and are excluded from the computation of diluted loss per share for such periods.
The following table reconciles the denominators used in the computations of both basic and diluted earnings per share:

Share-Based Compensation
13.Share-Based Compensation
The Compensation Committee of the Company’s Board of Directors is responsible for the administration of the Company’s stock incentive plans, which include the balance of shares remaining under the 2022 Long Term Incentive Plan (the “2022 LTIP”), which was approved by shareholders in May of 2022 and amended in May of 2024 and authorizes 3,735,000 shares, the maximum aggregate number to be issued, plus any shares available for grant under prior long term incentive plans as of the date the 2022 LTIP was approved, and any shares subject to awards granted under the prior plans that expire or are cancelled, forfeited, exchanged, settled in cash or otherwise terminated. In general, the Company’s 2022 LTIP provides for grants of restricted stock and performance-based awards to be issued with a per-share price not less than the fair market value of a share of common stock on the date of grant. The Company accounts for forfeitures of awards as they are incurred.
In May 2024 shareholders approved the ESPP, which became effective on September 16, 2024. The Company has reserved a total of 1,000,000 shares under the ESPP, all of which are authorized and available for future issuance under the ESPP. The ESPP provides a means by which eligible employees of the Company are given an opportunity to purchase shares of common stock at a discount as permitted under the Internal Revenue Code of 1986, as amended. During the three months ended March 31, 2025, there were 71,133 shares issued under the ESPP generating proceeds to the Company of $0.3 million. The Company has an outstanding liability
pertaining to the ESPP of less than $0.1 million as of March 31, 2025, included in accrued expenses, for employee contributions to the ESPP, pending issuance at the end of the offering period.

On March 20, 2025, the Company granted certain executives a total of 293,073 performance-based units. The performance-based units will potentially vest 100% if the target is met, with 50% of the units to be earned based on the achievement of an absolute adjusted EBITDA target, measured over a three-year performance period and 50% of the units to be earned based on the achievement of an objective, tiered return on relative total shareholder return, measured over a three-year performance period. The Company evaluates the probability of achieving this each reporting period. The fair value of the grants awarded related to the adjusted EBITDA target was $5.89 per share and the fair value of the grants awarded related to the relative total shareholder return was $8.45 valued using a Monte Carlo simulation model.

Summary of Significant Accounting Principles (Policies)

Mar. 31, 2025

Accounting Policies [Abstract]

Basis of Presentation
Basis of Presentation
The accompanying condensed consolidated financial statements and financial information included herein have been prepared pursuant to the interim period reporting requirements of Form 10-Q. Consequently, certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted. For the periods presented, there were no items of other comprehensive income, and therefore comprehensive loss is equal to net loss. Readers of this report should also read the Company’s consolidated financial statements, and the notes thereto included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (“2024 Form 10-K”) as well as Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations also included in its 2024 Form 10-K.
In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments considered necessary for a fair presentation of the Company’s financial position, results of operations, and cash flows for the periods presented. Such adjustments are of a normal recurring nature. Interim results of operations for the three months ended March 31, 2025 are not necessarily indicative of the results realizable for the year ending December 31, 2025.
In connection with preparing consolidated financial statements for each annual and interim reporting period, the Company is required to evaluate whether there are conditions or events, considered in aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within the one year period following the date that the financial statements are issued.
The assessment of the liquidity and going concern requires the Company to make estimates of future activity and judgments about whether the Company is compliant with financial covenant calculations under its debt and other agreements and has adequate liquidity to operate (See Note 9). Significant assumptions used in the Company's forecasted model of liquidity include forecasted sales, costs, our ability to manage spending on capital expenditures, our ability to complete certain asset sales and collect claims and unapproved change order revenue. Based on an assessment of these factors, management believes that the Company will have adequate liquidity for its operations for at least the next 12 months.

Recent Accounting Pronouncements
Recent Accounting Pronouncements
The Financial Accounting Standards Board (“FASB”) issues accounting standards and updates (each, an “ASU”) from time to time to its Accounting Standards Codification (“ASC”), which is the primary source of U.S. GAAP. The Company regularly monitors ASUs as they are issued and considers applicability to its business. All ASUs are adopted by their respective due dates and in the manner prescribed by the FASB.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments require disclosure of specific categories in the rate reconciliation and
provides additional information for reconciling items that meet a quantitative threshold and further disaggregation of income taxes paid for individually significant jurisdictions. The ASU is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. This will not impact our financial position or results of operations, but is expected to result in expanded tax disclosures in the full year financial statements for the year ended December 31, 2025.
In January 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures. The amendments require entities to provide enhanced disaggregation of certain expense categories presented in the income statement, including details on significant components within those categories, to provide greater transparency and decision-useful information to users of financial statements. The ASU is effective for fiscal years beginning after December 15, 2025, with early adoption permitted. The Company is currently evaluating the impact that this guidance will have on the disclosures within its consolidated financial statements.

Summary of Significant Accounting Principles (Policies)	Mar. 31, 2025
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements and financial information included herein have been prepared pursuant to the interim period reporting requirements of Form 10-Q. Consequently, certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted. For the periods presented, there were no items of other comprehensive income, and therefore comprehensive loss is equal to net loss. Readers of this report should also read the Company’s consolidated financial statements, and the notes thereto included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (“2024 Form 10-K”) as well as Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations also included in its 2024 Form 10-K. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments considered necessary for a fair presentation of the Company’s financial position, results of operations, and cash flows for the periods presented. Such adjustments are of a normal recurring nature. Interim results of operations for the three months ended March 31, 2025 are not necessarily indicative of the results realizable for the year ending December 31, 2025. In connection with preparing consolidated financial statements for each annual and interim reporting period, the Company is required to evaluate whether there are conditions or events, considered in aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within the one year period following the date that the financial statements are issued. The assessment of the liquidity and going concern requires the Company to make estimates of future activity and judgments about whether the Company is compliant with financial covenant calculations under its debt and other agreements and has adequate liquidity to operate (See Note 9). Significant assumptions used in the Company's forecasted model of liquidity include forecasted sales, costs, our ability to manage spending on capital expenditures, our ability to complete certain asset sales and collect claims and unapproved change order revenue. Based on an assessment of these factors, management believes that the Company will have adequate liquidity for its operations for at least the next 12 months.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The Financial Accounting Standards Board (“FASB”) issues accounting standards and updates (each, an “ASU”) from time to time to its Accounting Standards Codification (“ASC”), which is the primary source of U.S. GAAP. The Company regularly monitors ASUs as they are issued and considers applicability to its business. All ASUs are adopted by their respective due dates and in the manner prescribed by the FASB. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments require disclosure of specific categories in the rate reconciliation and provides additional information for reconciling items that meet a quantitative threshold and further disaggregation of income taxes paid for individually significant jurisdictions. The ASU is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. This will not impact our financial position or results of operations, but is expected to result in expanded tax disclosures in the full year financial statements for the year ended December 31, 2025. In January 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures. The amendments require entities to provide enhanced disaggregation of certain expense categories presented in the income statement, including details on significant components within those categories, to provide greater transparency and decision-useful information to users of financial statements. The ASU is effective for fiscal years beginning after December 15, 2025, with early adoption permitted. The Company is currently evaluating the impact that this guidance will have on the disclosures within its consolidated financial statements.
