DISCLOSURE CONTROLS AND PROCEDURES

The Registrant’s Chief Executive Officer and Chief Financial Officer have evaluated the effectiveness of the Registrant’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this annual report (the “Evaluation Date”). Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that, as of the Evaluation Date, the Registrant’s disclosure controls and procedures were effective to ensure that information required to be disclosed by the Registrant in reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission (the “SEC”) and (ii) accumulated and communicated to the Registrant’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management is responsible for establishing and maintaining adequate internal control over financial reporting for the Registrant. 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.

Due to its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of its 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.

Management has excluded eleven entities – Ethos Urban Pty Ltd., Triovest Inc., Astris Infrastructure, LLC, Greystone Sales Group, LLC, Terra Consulting, Higher Ground Consulting, Herold Engineering, Cambium Inc., LRL Associates Ltd., Greenhill Engineers Pty Ltd., RoundShield Partners LLP - acquired by the Company during the last fiscal period from its assessment of internal control over financial reporting as at December 31, 2025. The total assets and total revenues of the eleven majority-owned entities represent 1.7% and 2.3%, respectively of the related consolidated financial statement amounts as at and for the year ended December 31, 2025.

Management has assessed the effectiveness of the Registrant’s internal control over financial reporting as at December 31, 2025, based on the criteria set forth in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management has concluded that, as at December 31, 2025, the Registrant’s internal control over financial reporting was effective.

The effectiveness of the Registrant’s internal control over financial reporting as at December 31, 2025 has been audited by PricewaterhouseCoopers LLP, the Registrant’s independent registered public accounting firm, as stated in their report filed in Exhibit 2 of this Annual Report on Form 40-F.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

During the year ended December 31, 2025, there were no changes in the Registrant’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Registrant’s internal control over financial reporting.

NOTICES PURSUANT TO REGULATION BTR

There were no notices required by Rule 104 of Regulation BTR that the Registrant sent during the year ended December 31, 2025 concerning any equity security subject to a blackout period under Rule 101 of Regulation BTR.

AUDIT COMMITTEE FINANCIAL EXPERTS

The Registrant’s board of directors (the “Board of Directors”) has determined that it has one audit committee financial expert (as such term is defined in the note to paragraph 8(a) of General Instruction B to Form 40-F) serving on its audit & risk committee (the “Audit Committee”). Mr. L. Frederick Sutherland has been determined by the Board of Directors to be an audit committee financial expert and is independent (as such term is defined by the corporate governance standards of the NASDAQ Stock Market (“NASDAQ”) applicable to the Registrant).

Mr. Sutherland was the Executive Vice President and Chief Financial Officer of Aramark Corporation, Philadelphia, PA, a leading global provider of food services, facilities management and uniform and career apparel, from 1997 to 2015. Prior to joining Aramark in 1980, Mr. Sutherland was Vice President, Corporate Banking, at Chase Manhattan Bank, New York, NY. Mr. Sutherland is a director of Consolidated Edison, Inc. and a former director of Sterling Check Corp. Mr. Sutherland is a trustee, executive committee member and audit committee chair of Duke University, and a trustee and financial committee chair of the National Constitution Center.  Mr. Sutherland is also a former director and Chair of the Board of WHYY, Philadelphia’s public broadcast affiliate, a former trustee and chair of Episcopal Community Services, a Philadelphia-based anti-poverty agency and a former trustee and chair of People’s Light, a professional non-profit theater. Mr. Sutherland holds an MBA Degree in Finance from the Katz School of the University of Pittsburgh and a Bachelors in Physics and Mathematics from Duke University.

The SEC has indicated that the designation of Mr. Sutherland as an audit committee financial expert does not make him an “expert” for any purpose, impose on him any duties, obligations or liability that are greater than the duties, obligations or liability imposed on him as a member of the Audit Committee and the Board of Directors in absence of such designation, or affect the duties, obligations or liability of any other member of the Audit Committee or Board of Directors.

ANNUAL INFORMATION FORM

February 20, 2026

All amounts referred to in this Annual Information Form (“AIF”) are in United States dollars unless otherwise indicated. All financial and statistical data in this AIF is presented as at December 31, 2025 unless otherwise indicated.

Corporate structure

Colliers International Group Inc. (“we,” “us,” “our,” “Colliers,” or the “Company”) was formed under the Business Corporations Act (Ontario) by Articles of Arrangement dated June 1, 2015. The predecessor to the Company, FirstService Corporation (“Old FSV”), was formed by Articles of Incorporation dated February 25, 1988. Old FSV amalgamated with Coloma Resources Limited pursuant to Articles of Amalgamation dated July 31, 1988, and the amalgamated corporation continued as Old FSV.

By Articles of Amendment dated April 2, 1990, Old FSV: (i) consolidated each of its Class A Subordinate Voting Shares on a 30 to 1 basis and changed the designation of that class of shares to “Subordinate Voting Shares”, each such share carrying one vote; and (ii) consolidated each of its Class B shares on a 30 to 1 basis and changed the designation of that class of shares to “Multiple Voting Shares”, each such share carrying 20 votes. All of the Multiple Voting Shares have been controlled by Jay S. Hennick, our Chairman and Chief Executive Officer, from 1990 to present.

By Certificate of Amendment dated June 27, 2007, the first series of Preference Shares of Old FSV were created and designated as 7% cumulative preference shares, series 1 (the “Preferred Shares”), with each Preferred Share having a stated value of US$25.00 and carrying a fixed cumulative annual dividend of US$1.75. All outstanding Preferred Shares were eliminated on May 3, 2013 by way of a partial redemption for cash of $39.2 million immediately followed by a mandatory conversion of all then remaining Preferred Shares into Subordinate Voting Shares, which resulted in the issuance of 2.9 million new Subordinate Voting Shares.

On June 1, 2015, Old FSV completed a plan of arrangement (the “Spin-off”) which separated Old FSV into two independent publicly traded companies – Colliers, a global leader in diversified professional commercial real estate services and new FirstService Corporation (“FirstService”), the North American leader in residential property management and related services. The Spin-off was designed to enhance long-term value for shareholders by creating two independent and sustainable companies, each with the ability to pursue and achieve greater success by employing independent value creation strategies best suited to its core businesses and customers. Under the Spin-off, Old FSV shareholders received one Colliers share and one FirstService share of the same class as each Old FSV share previously held, Old FSV amalgamated with a wholly-owned subsidiary and changed its name to Colliers and FirstService adopted the name “FirstService Corporation”.

On April 16, 2021, after receiving approval from 95% of disinterested shareholders, the Company completed a transaction to settle the Management Services Agreement, including the Long Term Incentive Arrangement (“LTIA”), between Colliers, Mr. Hennick and Jayset Management CIG Inc., a corporation controlled by Mr. Hennick. This transaction also established a timeline for the orderly elimination of our dual class voting structure by no later than September 1, 2028.

On July 23, 2025, the Company announced the rebranding of its Investment Management division to Harrison Street Asset Management (“HSAM”). The Company also expanded HSAM’s leadership team, appointing co-founder Christopher Merrill as Global CEO of HSAM, along with Zachary Michaud and Stephen Gordon as Managing Partners & Global CFO and COO of HSAM, respectively.

Our Subordinate Voting Shares are publicly traded on both the Toronto Stock Exchange (“TSX”) (symbol: CIGI) and the NASDAQ Stock Market (“NASDAQ”) (symbol: CIGI). Our head and registered office is located at 1140 Bay Street, Suite 4000, Toronto, Ontario, M5S 2B4. Our fiscal year-end is December 31.

Intercorporate Relationships

We have the following principal subsidiaries which have total assets or revenues which exceed 10% of our total consolidated assets or revenues as at and for the year ended December 31, 2025:

The above table does not include all of the subsidiaries of Colliers.

General development of the business

Our origins date back to 1972 when Mr. Hennick started a Toronto commercial swimming pool and recreational facility management business, which became the foundation of Old FSV. In 1993, we completed our initial public offering on the TSX, raising C$20 million. In 1995, our shares were listed on NASDAQ. In 1997, a second stock offering was completed in Canada and the United States raising US$20 million. In December 2004, a stock dividend was declared effectively achieving a 2-for-1 stock split for all outstanding Subordinate Voting Shares and Multiple Voting Shares. In 2009, Old FSV issued $77 million of convertible unsecured subordinate debentures, which were subsequently converted into 2.7 million Subordinate Voting Shares in 2014. In 2020, the Company issued $230 million of Convertible Senior Subordinate Notes (“Convertible Notes”), which were subsequently converted into 4.0 million Subordinate Voting Shares in 2023. In 2024, the Company completed a $300 million public offering of equity, issuing 2.5 million Subordinate Voting Shares.

In 2004, we established a commercial real estate services division under the “Colliers International” brand with the acquisition of Colliers Macaulay Nicolls Inc. (“CMN”). Since that time, we have strengthened this business across markets and acquired numerous businesses within existing and new markets, greatly expanding its geographic scope, services and talent. Today, Colliers is one of the world’s largest commercial real estate services providers offering a full range of commercial real estate services in the United States, Canada, Australia, the United Kingdom, Germany, New Zealand, China and several other countries in Asia, Europe and Latin America.

In 2015, we completed the Spin-off, creating two independent publicly traded companies: Colliers in commercial real estate services and FirstService in residential property management and related services. Commencing at such time, Colliers began a transformation with a focus on becoming a global, diversified professional services and investment management company. Since 2016, the Company has invested in two new high-value and resilient platforms – Engineering and Investment Management – both with significant growth potential.

Commercial Real Estate (previously named Real Estate Services)

At the time of the Spin-off, Colliers was one of the fastest growing global commercial real estate services companies. The Company has since completed multiple acquisitions, including certain licensee affiliates, as well as entered new geographies and service lines.

In May 2020, we acquired a controlling interest in four subsidiaries of Dougherty Financial Group LLC – Dougherty Mortgage LLC, Dougherty & Company LLC, Dougherty Funding LLC and Dougherty Insurance Agency LLC (together “Dougherty”). Dougherty’s mortgage banking operations were rebranded as “Colliers Debt & Structured Finance” which provides specialty debt financing through its relationships with US government agencies while all brokerage, investment banking, capital markets and public finance services are carried on through “Colliers Securities” which is licensed under the Securities and Exchange Commission and is a member of the Financial Industry Regulatory Authority (“FINRA”).

With continued investments in talent and capabilities, strong operational leadership and strategic acquisitions, the Company continues to serve a wide range of clients across diverse asset classes worldwide.

Investment Management (Harrison Street Asset Management)

Colliers established its Investment Management division in 2016 with the acquisition of ICADE Asset Management and ICADE Conseil (“ICADE”), an asset management and investor advisory services platform in France with €2 billion of assets under management (“AUM"- see “Reconciliation of non-GAAP financial measures”) in Europe.

In 2018, we acquired a controlling interest Harrison Street Real Estate Capital, LLC (“Harrison Street”), a real estate investment firm dedicated to demographic-themed direct private investing with $15.6 billion in AUM as of June 30, 2018. The senior management team of Harrison Street holds the balance of the equity. Headquartered in Chicago, with offices in New York, San Francisco, Washington, D.C., Toronto, Tokyo and London. Harrison Street is a pioneer in demographic-themed real estate investing.

In April 2022, we completed the acquisition of controlling interests in Antirion SGR S.p.A. (“Antirion”), a real estate investment management firm in Italy, and its commercial real estate services affiliate, Colliers Italy. Antirion was subsequently rebranded as Colliers Global Investors.

In June 2022, we acquired a controlling interest in Basalt Infrastructure Partners LLP (“Basalt”), a London-based transatlantic infrastructure investment management firm. Basalt is focused on private direct mid-market investments in the utility, transportation, energy/renewables and communications sectors.

In July 2022, we completed the acquisition of a controlling interest in Rockwood Capital, LLC (“Rockwood”), a US real estate investment management firm. Rockwood specializes in equity and credit investments across multifamily, office, mixed use, life science, hospitality, and retail asset classes in North America.

In October 2022, we acquired a controlling interest in Versus Capital (“Versus”), a US alternative real asset management firm with private wealth distribution capabilities and a series of perpetual funds targeted at this investor class.

In July 2025, the Company acquired a controlling interest in RoundShield Partners LLP, a European credit investment management firm with $5.4 billion in AUM.

Under the HSAM umbrella, the Company has further expanded its global distribution capabilities, targeting new strategies, geographies and platforms, while leveraging the strength, breadth and global recognition of the Harrison Street brand. As part of the HSAM rebranding and internal restructuring of this business, our economic interest in HSAM is presently 82%. As of December 31, 2025, the Company had $108 billion in AUM, driven by both internal growth and acquisitions.

Engineering

In 2020, we acquired a controlling interest in Maser Consulting P.A. (“Maser”), a multi-disciplinary engineering design and consulting firm operating in the US Mid-Atlantic region, which was our entry into the engineering sector. The operation was rebranded as “Colliers Engineering & Design” in 2021. We followed this with several acquisitions in the US to enhance our technical service capabilities and expand geographically.

In August 2022, we acquired a controlling interest in PeakUrban Pty Limited (“PeakUrban”), a civil engineering, infrastructure, planning and urban design company in Australia, thereby establishing an engineering service line in the country. The business has rebranded as Colliers Engineering & Design and has since completed several additional business acquisitions.

In July 2024, we added engineering capabilities in Canada with the acquisition of a controlling interest in Englobe Corporation (“Englobe”), a multi-discipline engineering, environmental and inspection services firm with 2,800 employees.

Effective in the third quarter of 2024, the Company combined its existing project management operations with engineering under a new reporting segment – “Engineering” – to better reflect the nature of the technical professional services, operating characteristics, clients and growth of this platform.

The company completed the acquisition of seven tuck-in operations in 2025 and two in 2026, primarily in the US, Canada and Australia to enhance service capabilities as well as to expand market share.

In February 2026, the Company entered into a definitive agreement to acquire Ayesa Engineering S.A.U. (“Ayesa Engineering”), a 3,200-person multi-discipline engineering and project management firm headquartered in Spain. The transaction is expected to close in the second quarter of 2026, subject to customary closing conditions, including various regulatory approvals.

Narrative description of Colliers

History

CMN traces its roots back to 1898 when Macaulay Nicolls was founded in Vancouver, Canada as a property management and insurance agency. Colliers originated in 1976 in Australia through the merger of three commercial property services firms. In 1984, Colliers joined forces with Macaulay Nicolls to form CMN. Over the years, CMN continued to grow as other commercial real estate service providers joined the group. In 2004, Old FSV acquired a controlling interest in CMN. At the time of the acquisition by Old FSV, CMN was the largest affiliate of Colliers International generating approximately $250 million in annual revenue.

With the financial and strategic support of Old FSV, CMN accelerated its growth by expanding into complementary service areas and growing into other geographic regions. By 2010, Old FSV had unified all operations under the “Colliers International” brand name with one mission and standardized business practices delivered consistently globally.

Following the 2015 Spin-off, Colliers, as an independent public company, began to pursue a strategy of diversifying its business with a focus on adding complimentary high-value professional services. In 2016, we entered the Investment Management sector and in 2020 we entered the Engineering sector.

A summary of Colliers’ history and growth initiatives to date is as follows:

Segment Descriptions

The Company’s financial results are segmented under three segments: (i) Commercial Real Estate; (ii) Engineering and (iii) Investment Management.

Global diversified professional services and investment management company

Commercial Real Estate

We are one of the top global providers of professional commercial real estate services to owners, occupiers and investors. From essential transaction and debt finance services to outsourcing in Property Management, Valuation & Advisory and Loan Servicing, our services span the commercial real estate spectrum. Our 4,600 professional advisors in Capital Markets and Leasing, and 4,200 professionals in Outsourcing work with all asset classes, including office, industrial, data centers, retail, multi-family, hospitality, health care and mixed-use properties. In 2025, we completed 44,000 sale and lease transactions for a total transaction value of $112 billion and managed 2.0 billion square feet.

Capital Markets

Our Capital Markets services include property sales brokerage for commercial clients as well as debt finance services related to the origination and sale/placement of mortgage loans. Our advisors assist buyers and sellers with the acquisition or disposition process and assist borrowers and lenders with the financing process. Our advisors typically perform their services for commissions calculated based on the value of a transaction. We execute transactions across a diverse client base, including corporations, financial institutions, pension funds, sovereign wealth funds, insurance companies, governments and individuals.

Capital Markets Revenues by Asset Class

We provide Capital Markets services in the following areas:

Leasing

We provide Lease brokerage services to owners and occupiers of commercial real estate across all major asset classes. We have long-standing relationships with both large and medium-sized occupiers and owners. Our services are engaged on a repeat basis for lease renewals and relocations.

Outsourcing

Our Outsourcing services include Property Management, Valuation & Advisory and Loan Servicing. In addition, we consult with large occupiers in managing their overall real estate portfolios and transactions, providing corporate and workplace solutions to reduce costs, improve execution across multiple markets and increase operational efficiency. Professional staff combine proprietary technology with high level strategic planning, portfolio management, lease administration and facilities management to deliver bespoke solutions to our clients. Outsourcing services revenues are derived from fees which are typically contractual, both fixed and fee for service, and contract terms are often multi-year providing recurring or repeat revenues.

Outsourcing Revenues by Service

Our Outsourcing services include:

Engineering

We are a rapidly growing player in the engineering design and consulting, project management, architectural and environmental services sector, with more than 9,600 employees globally. Backed by strong infrastructure renewal, energy transition and urbanization tailwinds, the engineering sector is a large and highly fragmented market with opportunities to grow internally and consolidate through acquisitions.

Since we first established Colliers Engineering & Design in 2020 with the acquisition of Maser, we have grown to become one of the top 50 global design firms based on Engineering News Record’s annual ranking. Our vision is to lead the industry with proven expertise and innovative, sustainable solutions through exceptional work and client experience. Our client base is diversified with a balanced mix of both public and private sector clients. Our client-centered approach enables us to foster long-term relationships which translate to repeat work from our clients. As a result of our focus on service and client diversification, our business is resilient, allowing us the ability to respond to changing market conditions quickly and effectively.

Engineering Revenues by Geography

We offer a full range of consulting and engineering design services for four end markets: property & buildings, infrastructure & transportation, environmental services and water. Our professionals include licensed engineers, project managers, planners, surveyors, architects and environmental scientists. Colliers works across a variety of engineering disciplines, including, civil, surveying, design, inspection, planning, project management, program management and other adjacencies.

Engineering End Markets Exposure

Property & Buildings: We work with owners throughout the building lifecycle, including conducting highest and best use studies, feasibility assessments, detailed design and construction management. We are a full-service firm, providing expertise in commercial, industrial, government and education buildings. We offer land development and monitoring services, including for residential, commercial, industrial and renewable energy sectors.

Infrastructure & Transportation: Our professionals engage with public and private clients to plan, design and project manage their assets, including bridges & structures, highway and traffic planning and engineering, construction engineering and inspection, power generation and transmission, mining, marine and rail. We have long-standing relationships with federal, state/provincial and municipal government agencies as well as large utility, telecom and rail firms.

Environmental Services: Our environmental experts offer a range of service to our public and private sector clients, including air quality assessments, brownfield redevelopment, environmental impact assessments, ground water resource development, site remediation, and noise studies, among others. We also have geotechnical capabilities, including geotechnical engineering, geo-structural design, construction observation and testing, as well as laboratory material testing services.

Water: We offer expertise in water, storm and wastewater management in all areas of feasibility, design and master planning. Our services span from capital improvements and system planning, to design of municipal and industrial treatment plants, water distribution systems, distribution system modeling, wastewater collection and treatment, hydrogeologic investigations and environmental assessments.

We provide project management services for a wide range of projects globally, typically acting as the owner’s representative, across our four end markets. These services stretch from conception to the final commissioning of the asset. Services include bid document review, construction monitoring and delivery management, contract administration and integrated cost control, development management, facility and engineering functionality, milestone and performance monitoring, quality assurance, risk management and strategic project consulting.

The majority of our contracts are medium to long-term in duration. Clients generally have a portfolio of assets which leads to opportunities for repeat business and the development of long-term relationships. Contracts are structured on a fixed price or cost-plus basis. Our Engineering business strives to maintain a backlog of contracted work spanning approximately one year, which provides visibility and predictability for future revenues and enables efficient workforce planning.

Investment Management

Our Investment Management segment is a global alternative asset manager with long-standing, cycle-tested expertise across high growth and defensive sectors within real assets. Our differentiated approach focuses on long-duration, demographic, needs-based and essential real assets; middle-market infrastructure like communications, transport, energy, and utilities; real asset private credit; and core and opportunistic real estate strategies. We invest capital for the long-term through our differentiated strategies that have strong tailwinds, are resilient through cycles, and are designed to deliver top-tier risk-adjusted returns. We serve more than 1,200 investors across the globe, including institutions, sovereign wealth funds, public and corporate pension funds, endowments, insurance companies, foundations and family offices, with the majority invested in more than one fund.

Since 2016, when we first established Investment Management operations in Europe, with the acquisition of ICADE, our platform has grown substantially, fueled by strong fundraising across all our products and investment vehicles. In 2018, we acquired Harrison Street and established our Investment Management segment.

In 2022, the Company significantly expand its investment management capabilities, acquiring majority ownership interests in four firms (Antirion, Basalt, Rockwood and Versus) across curated product types, including infrastructure, alternatives, traditional real estate and credit in North America and Europe, with a specific focus on long-duration funds. In 2025, the Company acquired a controlling interest in RoundShield to further enhance its capabilities in the private credit sector.

As of December 31, 2025, the Company had $108.2 billion of AUM, with 86% in perpetual or long-dated investment strategies. We deploy capital across four main investments strategies, namely, alternative real estate, infrastructure, traditional real estate and credit, with more than 71% deployed in highly defensive alternative real estate and infrastructure asset classes. The Company’s fee-paying assets under management (“FPAUM”) (See “Reconciliation of non-GAAP financial measures”) were $54.2 billion as of December 31, 2025.

Long Duration, Highly Differentiated AUM

The Company’s investment products consist of (i) perpetual funds, (ii) long-dated funds and (iii) separately managed accounts. We generate contractual management fee revenue from each of the funds and separately managed accounts under our management and have an opportunity to generate performance fee revenues on long-dated funds under our management.

Perpetual (open-end) funds

In our perpetual funds, management fees are based on net asset value (“NAV”). NAV is calculated quarterly using data from third party valuation advisors to determine the current market value of the private real estate and real assets in the funds.

Investors in our perpetual funds may invest on a quarterly basis at the then-current NAV. Investors can also request to have their interests redeemed on a periodic basis, at the then-current NAV. There are typically restrictions around redemption requests, including lock-up periods and gating provisions that restrict the amount that can be redeemed in any quarterly period in order to preserve fund liquidity and to ensure the efficient operation of the fund for the benefit of all investors. We also have flexibility in the timing of funding redemptions given the underlying illiquid nature of the funds’ private real estate and real assets.

Long-dated (closed-end) funds

Our long-dated funds typically have a ten-year term with two one-year extensions, at the option of the manager.

We generate management fees based on committed capital or invested capital in these funds. Committed capital is used to calculate fees during the investment period, which typically comprises the first 3 years of a fund’s life. Management fees commence on the date of a fund’s “first close”, which is the date that the initial investors legally commit to invest in the fund. Additional investors may commit to invest in the fund during the investment period, however they are required to pay management fees from the “first close” date. This results in our recognition of “catch-up” management fees when such investors make commitments after the first close date. After the end of the investment period, the management fee is calculated based on invested capital, which is typically 90-95% of the committed capital amount.

In addition to the contractual management fee, we are also entitled to earn performance fees (sometimes referred to as carried interest) on long-dated funds, provided that we meet or exceed certain contractually agreed preferred return targets. Carried interest revenue is recognized when it is highly probable that such return targets will be exceeded, typically when the fund is near the end of its life and the underlying fund assets have been sold or are in the process of being sold. Colliers is only entitled to receive carried interest on funds established on or after acquisition dates of its Investment Management firms. Historical carried interest on funds established prior to acquisition dates is structured as a pass-through to the prior owners with no impact on the Company’s earnings.

Management fee revenue is expected to be relatively stable and recurring due to: (i) historically consistent fund financial performance at or exceeding industry benchmarks, which we anticipate will continue in the future; (ii) the generally defensive nature of the sectors being invested in by the funds; and (iii) management fees for long-dated funds based on committed capital or invested capital rather than marked-to-market NAV, providing for revenue stability throughout the life of the funds.

Separately managed accounts

The Company also has separately managed accounts (“SMAs”) where we agree to provide investment management services to individual institutional investors to fulfill their specific long-term investment objectives, investing directly in private real estate and real assets. SMAs are subject to contractual management agreements, with management fees earned based on NAV and/or as a transaction fee in connection with the acquisition or disposition of assets.

Focus on recurring service lines

Over the last ten years, Colliers has focused on growing its high-value recurring revenue streams – Outsourcing, Engineering and Investment Management. These services represent medium to long-term duration revenue streams that are contractual or repeatable in nature. Recurring services are not only more resilient, given the nature of the underlying contracts, but also provide visibility for operational planning and for identifying growth areas. As of December 31, 2025, we generated more than 70% of our earnings from recurring revenue sources (see “Reconciliation of non-GAAP financial measures”).

Our growth strategy

Our long-standing growth strategy, which we refer to as “The Colliers Way” is the foundation of our success. The key principles of The Colliers Way are described below:

Sustainability strategy

In 2021, the Company announced its ‘Elevate the Built Environment’ strategic framework designed to embed sustainability best practices across the organization. In addition, Colliers committed to setting a science-based target through the Science-Based Targets initiative’s (SBTi) Business Ambition for 1.5°C program as well as achieving Carbon Neutrality for the Company’s own operations by 2030. The Company refreshed its sustainability framework strategy, ‘Built to Last’, in conjunction with an updated materiality study in 2025. The key components of the strategy are detailed below:

Governance structures and working groups have been established to execute on each of these objectives. The Company publishes an annual Global Impact Report outlining its commitments, performance, and progress. This report is released in June each year and can be found on the Company’s website.

Geographic locations

We deliver services from 493 offices in 33 countries (not including non-owned licensee/affiliates). Operationally, we have organized our business and report our results through three segments. For the year ended December 31, 2025:

Below is a map reflecting the geographic location of our company-owned and affiliate offices:

Operating segments

Seasonality

The Company historically generates peak revenues and earnings in the month of December followed by a low in January and February as a result of the seasonal timing of closings on Capital Markets transactions. Revenues and earnings during the balance of the year are relatively even. The Capital Markets operations comprised 16% of our 2025 annual consolidated revenues. Variations can also be caused by business acquisitions or dispositions which alter the consolidated service mix.

Trademarks

Our trademarks are important for the advertising and brand awareness of our businesses. We take precautions to defend the value of our trademarks by maintaining legal registrations and by litigating against alleged infringements, if necessary.

In certain Real Estate Services markets where we do not have company-owned operations, independent affiliates operate using the “Colliers International” and “Colliers” brands and trademarks under license from us. To ensure brand unity and service quality, all affiliates are subject to brand and performance guidelines that are monitored and enforced by Colliers. We currently have affiliates in 37 countries around the world who together generated approximately $494 million in revenue in 2025, which not included in the Company’s consolidated results. In 2025, our affiliates completed 13,000 sales and lease transactions for a total transaction value of $16 billion.

Employees

We currently have approximately 24,000 employees worldwide as follows:

Non-controlling interests

Creating strong employee engagement and alignment through our “partnership philosophy” (the ownership of equity in the business) is one of our key operating principles.

^{_________________________________________}

¹  Adjusted EBITDA is a financial measure that is not calculated in accordance with GAAP. For a reconciliation of this and other non-GAAP financial measures, see “Reconciliation of non-GAAP financial measures” in this AIF.

In many cases, operating management teams of our majority-owned subsidiaries own minority equity stakes in the businesses they operate day-to-day. This structure was designed to maintain control at Colliers while providing significant risks and rewards of equity ownership to management at the operating businesses. In almost all cases, we have the right to “call” management’s shares, usually payable at our option with any combination of Subordinate Voting Shares or cash. We may also be obligated to acquire certain of these non-controlling interests in the event of death, disability or cessation of employment or if the shares are “put” by the holder, subject to annual limitations on these puts imposed by the relevant shareholder agreements. These arrangements provide significant flexibility to us in connection with management succession planning and shareholder liquidity matters.

Dividends and dividend policy

Dividend policy

Following the 2015 Spin-off, our Board of Directors approved a dividend policy for the Company, which was a dividend of $0.08 per Subordinate Voting Share and Multiple Voting Share per annum, payable semi-annually. On May 31, 2016, the Board of Directors increased the semi-annual dividend from $0.04 to $0.05 per Subordinate Voting Share and Multiple Voting Share ($0.10 per annum). On December 7, 2021, the Board of Directors further increased the semi-annual dividend from $0.05 to $0.15 per Subordinate Voting Share and Multiple Voting Share ($0.30 per annum). These dividends are paid in cash after the end of the second and fourth quarters. All dividend payments are subject to the discretion of our Board of Directors. For the purposes of the Income Tax Act (Canada) and any similar provincial legislation, all dividends on the Subordinate Voting Shares and Multiple Voting Shares will be eligible dividends unless indicated otherwise.

The terms of the dividend policy remain, among other things, at the discretion of our Board of Directors. Future dividends, if any, will depend on the results of Colliers’ operations, cash requirements, financial condition, contractual restrictions, business opportunities, provisions of applicable law and other relevant factors. Under the terms of the Company’s debt agreements, the Company is not permitted to pay dividends, whether in cash or in specie, in the circumstances of an event of default thereunder occurring and continuing or an event of default occurring as a consequence thereof. See “Material contracts” below.

Dividend history

The aggregate cash dividends declared per Subordinate Voting Share and Multiple Voting Share in respect of each of the years ended December 31, 2025, 2024 and 2023 were $0.30 per year.

Capital structure

Share capital

The authorized capital of the Company consists of an unlimited number of preference shares (the “Preference Shares”), issuable in series, an unlimited number of Subordinate Voting Shares and an unlimited number of Multiple Voting Shares.

Colliers may purchase its Subordinate Voting Shares, from time to time, if it believes that the market price of its Subordinate Voting Shares is attractive and that the purchase would be an appropriate use of corporate funds and in the best interests of the Company. The Company did not repurchase any shares in 2025. As of February 20, 2026, there were 49,778,127 Subordinate Voting Shares and 1,325,694 Multiple Voting Shares issued and outstanding.

Subordinate Voting Shares and Multiple Voting Shares

The Subordinate Voting Shares and Multiple Voting Shares rank junior to the Preference Shares or series thereof ranking in priority with respect to the payment of dividends, return of capital and distribution of assets in the event of liquidation, dissolution or any distribution of the assets of Colliers for the purpose of winding-up its affairs. The holders of outstanding Subordinate Voting Shares and Multiple Voting Shares are entitled to receive dividends and other distributions on a share-for-share basis (or, in the discretion of the directors, in a greater amount per Subordinate Voting Share than per Multiple Voting Share) out of the assets legally available therefor at such times and in such amounts as our Board of Directors may determine, but without preference or distinction between the Multiple Voting Shares and the Subordinate Voting Shares. The Subordinate Voting Shares carry one vote per share and the Multiple Voting Shares carry 20 votes per share. The holders of Subordinate Voting Shares and the holders of Multiple Voting Shares are entitled to receive notice of any meeting of shareholders and to attend and vote thereat as a single class on all matters to be voted on by the shareholders, except at meetings where the holders of shares of one class or of a particular series of shares are entitled to vote separately.

The rights, privileges, conditions and restrictions attaching to the Subordinate Voting Shares and the Multiple Voting Shares may be respectively modified if the amendment is authorized by at least two-thirds of the votes cast at a meeting of the holders of Subordinate Voting Shares and the holders of Multiple Voting Shares duly held for that purpose. However, if the holders of Subordinate Voting Shares, as a class, or the holders of Multiple Voting Shares, as a class, are to be affected in a manner different from the other classes of shares, such amendment must, in addition, be authorized by at least two-thirds of the votes cast at a meeting of the holders of the class of shares which is affected differently.

Each outstanding Multiple Voting Share is convertible at any time, at the option of the holder and without further consideration, into one Subordinate Voting Share. The Subordinate Voting Shares are not convertible into any other class of shares, except in certain circumstances relating to a take-over bid, as described in the section entitled “Certain Rights of Holders of Subordinate Voting Shares” contained in the most recent Management Information Circular filed on Colliers’ SEDAR+ profile at www.sedarplus.ca. No subdivision, consolidation, reclassification or other change of the Multiple Voting Shares or the Subordinate Voting Shares may be made without, concurrently, having the Multiple Voting Shares or Subordinate Voting Shares, as the case may be, subdivided, consolidated, reclassified or other change made under the same conditions. The Subordinate Voting Shares and Multiple Voting Shares are not redeemable nor retractable but are able to be purchased for cancelation by Colliers in the open market, by private contract or otherwise. Upon the liquidation, dissolution or any distribution of the assets of Colliers for the purpose of winding-up its affairs, the holders of Subordinate Voting Shares and Multiple Voting Shares are entitled to participate equally, on a share-for-share basis, in the remaining property and assets of Colliers available for distribution to such holders.

In accordance with the terms and conditions of a trust agreement entered into by Mr. Hennick and Henset Capital Inc. (the “Multiple Voting Shareholder”) on April 16, 2021 (the “New Trust Agreement”) (see “Material Contracts” below), the Multiple Voting Shares will convert into Subordinate Voting Shares on a one-for-one basis and for no additional consideration or premium upon the earliest to occur of: (a) the date that the sum of the number of Multiple Voting Shares and Subordinate Voting Shares held by Mr. Hennick and the Multiple Voting Shareholder, together with their associates and affiliates, is less than 4,000,000 (subject to adjustment and including ownership of securities convertible into Subordinate Voting Shares); (b) 24 months after the termination of the New MSA (as defined below) as a result of Mr. Hennick’s death, disability, voluntary resignation or the occurrence of certain other specific events set out in the New MSA; and (c) September 1, 2028. Additionally, the New Trust Agreement provides that Mr. Hennick and the Multiple Voting Shareholder will not sell any Multiple Voting Shares at a price greater than the market price of the Subordinate Voting Shares on the date of the agreement to sell such shares unless through the facilities of the NASDAQ or TSX, pursuant to a take-over bid, or similar transaction, where there is a concurrent offer made to, or acquisition from, the holders of all of the Subordinate Voting Shares on terms that are at least as favorable to the holders of Subordinate Voting Shares as those made to Mr. Hennick or the Multiple Voting Shareholder, pursuant to an issuer bid or pursuant to the granting of a permitted security interest.

Preference Shares

The Preference Shares are issuable, from time to time, in one or more series, as determined by our Board of Directors. Our Board of Directors will determine, before the issue of any series of Preference Shares, the designation, preferences, rights, restrictions, conditions, limitations, priorities as to payment of dividends and/or distribution on liquidation, dissolution or winding-up, or prohibitions attaching to such series. The Preference Shares, if issued, will rank prior to the Subordinate Voting Shares and Multiple Voting Shares with respect to the payment of dividends and in the distribution of assets in the event of liquidation, dissolution or winding-up of Colliers or any other distribution of assets of Colliers among its shareholders for the purpose of winding-up its affairs, and may also be given such other preferences over the Subordinate Voting Shares and Multiple Voting Shares as may be determined with respect to the respective series authorized and issued. Except as required by law, the Preference Shares will not carry voting rights.

Certain rights of holders of Subordinate Voting Shares

A summary of the rights attaching to the Subordinate Voting Shares in the event that a take-over bid is made for Multiple Voting Shares is set out in the section entitled “Certain Rights of Holders of Subordinate Voting Shares” contained in our most recent Management Information Circular, which is incorporated by reference herein and is available on SEDAR+ at www.sedarplus.ca. Reference should be made to our articles for the full text of these provisions.

Option Plan

Colliers has a stock option plan (the “Option Plan”) pursuant to which options to acquire Subordinate Voting Shares may be granted to directors, officers and full-time employees of Colliers or its subsidiaries (other than Mr. Hennick). A summary of the terms of the Option Plan is set out in the section entitled “Executive Compensation – Incentive Award Plans of Colliers – Stock Option Plan” contained in the 2026 Circular, which shall be incorporated by reference herein and will be available on SEDAR+ at www.sedarplus.ca. The maximum number of Subordinate Voting Shares subject to grants of options under the Option Plan is limited to 12,100,000, which reflects the cumulative number of options approved by shareholders since the Option Plan’s inception in 2004. Options exercisable for 3,430,780 Subordinate Voting Shares have been granted and are outstanding as at the date hereof; and options which were exercisable for 6,830,395 Subordinate Voting Shares have been exercised or expired as at the date hereof, leaving options yet to be granted which would be exercisable for 1,838,825 Subordinate Voting Shares.

Market for securities

The outstanding Subordinate Voting Shares are listed for trading on the TSX and NASDAQ under the symbol “CIGI”. The Multiple Voting Shares are not listed and do not trade on any public market or quotation system.

The following table sets forth the reported high and low trading prices and the aggregate volume of trading of the Subordinate Voting Shares on NASDAQ (in United States dollars) and on the TSX (in Canadian dollars) for each month in 2025.

Escrowed securities and securities subject to contractual restriction on transfer

To the knowledge of Colliers, as of the date hereof, no securities of any class of securities of Colliers are held in escrow or subject to contractual restrictions on transfer or are anticipated to be held in escrow or subject to contractual restrictions on transfer.

Ownership

As of February 20, 2026, the directors and executive officers of the Company, as a group, owned, or controlled or directed, directly or indirectly, 5,920,538 Subordinate Voting Shares and 1,325,694 Multiple Voting Shares, which represent 11.9% of the total Subordinate Voting Shares and 100.0% of the total Multiple Voting Shares, in each case, outstanding on such date. The directors and executive officers, as a group, controlled 42.5% of the total voting rights as of such date when all Multiple Voting Shares and Subordinate Voting Shares are considered. Mr. Hennick controls all of the Multiple Voting Shares.

Legal proceedings and regulatory actions

There are no legal proceedings to which Colliers is a party to, or in respect of which, any of the property of Colliers is the subject of, which is or was material to Colliers during 2025, and Colliers is not aware of any such legal proceedings that are contemplated. In the normal course of operations, Colliers is subject to routine immaterial claims and litigation incidental to its business. Litigation currently pending or threatened against Colliers includes disputes with former employees and commercial liability claims related to services provided by Colliers. Colliers believes resolution of such proceedings, combined with amounts set aside, will not have a material impact on the Company’s financial condition or the results of operations.

During 2025, there have not been any penalties or sanctions imposed against Colliers by a court relating to provincial and territorial securities legislation or by a securities regulatory authority, nor have there been any other penalties or sanctions imposed by a court or regulatory body against Colliers, and Colliers has not entered into any settlement agreements before a court relating to provincial and territorial securities legislation or with a securities regulatory authority.

Properties

As at December 31, 2025, the Company leased 4,065,000 square feet of office space across the world, which included:

In addition, the Company owns 20,000 square feet of office space for its corporate headquarters.

Reconciliation of non-GAAP financial measures

In this AIF, we make reference to certain financial measures that are not calculated in accordance with GAAP.

Adjusted EBITDA is defined as net earnings, adjusted to exclude: (i) income tax; (ii) other income; (iii) interest expense; (iv) loss on disposal of operations; (v) depreciation and amortization, including amortization of mortgage servicing rights (“MSRs”); (vi) gains attributable to MSRs; (vii) acquisition-related items (including contingent acquisition consideration fair value adjustments, contingent acquisition consideration-related compensation expense and transaction costs); (viii) restructuring costs and (ix) stock-based compensation expense, including related to the CEO’s performance-based long-term incentive plan (“LTIP”). We use Adjusted EBITDA to evaluate our own operating performance and our ability to service debt, as well as an integral part of our planning and reporting systems. Additionally, we use this measure in conjunction with discounted cash flow models to determine the Company’s overall enterprise valuation and to evaluate acquisition targets. We present Adjusted EBITDA as a supplemental measure because we believe such measure is useful to investors as a reasonable indicator of operating performance because of the low capital intensity of the Company’s service operations. We believe this measure is a financial metric used by many investors to compare companies, especially in the services industry. This measure is not a recognized measure of financial performance of the consolidated Company under GAAP in the United States, and should not be considered as a substitute for operating earnings, net earnings or cash flow from operating activities, as determined in accordance with GAAP. Our method of calculating Adjusted EBITDA may differ from other issuers and accordingly, this measure may not be comparable to measures used by other issuers. A reconciliation of net earnings to Adjusted EBITDA appears below

Adjusted EPS is defined as diluted net earnings per share adjusted for the effect, after income tax, of: (i) the non-controlling interest redemption increment; (ii) loss on disposal of operations; (iii) amortization expense related to intangible assets recognized in connection with acquisitions and MSRs; (iv) gains attributable to MSRs; (v) acquisition-related items; (vi) restructuring costs and (vii) stock-based compensation expense, including related to the CEO’s LTIP. We believe this measure is useful to investors because it provides a supplemental way to understand the underlying operating performance of the Company and enhances the comparability of operating results from period to period. Adjusted EPS is not a recognized measure of financial performance under GAAP, and should not be considered as a substitute for diluted net earnings per share from continuing operations, as determined in accordance with GAAP. Our method of calculating this non-GAAP measure may differ from other issuers and, accordingly, this measure may not be comparable to measures used by other issuers. A reconciliation of net earnings to adjusted net earnings and of diluted net earnings per share to adjusted EPS appears below

We believe that the presentation of adjusted EBITDA and adjusted earnings per share, which are non-GAAP financial measures, provides important supplemental information to management and investors regarding financial and business trends relating to the Company’s financial condition and results of operations. We use these non-GAAP financial measures when evaluating operating performance because we believe that the inclusion or exclusion of the items described above, for which the amounts are non-cash or non-recurring in nature, provides a supplemental measure of our operating results that facilitates comparability of our operating performance from period to period, against our business model objectives, and against other companies in our industry. We have chosen to provide this information to investors so they can analyze our operating results in the same way that management does and use this information in their assessment of our core business and the valuation of the Company. Adjusted EBITDA and adjusted earnings per share are not calculated in accordance with GAAP, and should be considered supplemental to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. Non-GAAP financial measures have limitations in that they do not reflect all of the costs or benefits associated with the operations of our business as determined in accordance with GAAP. As a result, investors should not consider these measures in isolation or as a substitute for analysis of our results as reported under GAAP.

Adjusted EBITDA from recurring revenue percentage is computed on a trailing twelve-month basis and represents the proportion of Adjusted EBITDA that is derived from Engineering, Outsourcing and Investment Management service lines. All these service lines represent medium to long-term duration revenue streams that are either contractual or repeatable in nature. Adjusted EBITDA for this purpose is calculated in the same manner as for our debt agreement covenant calculation purposes, incorporating the expected full year impact of business acquisitions and dispositions.

Free cash flow is defined as net cash flow from operating activities plus contingent acquisition consideration paid, less purchases of fixed assets, plus cash collections on AR Facility deferred purchase price less distributions to non-controlling interests. We use free cash flow as a measure to evaluate and monitor operating performance as well as our ability to service debt, fund acquisitions and pay dividends to shareholders. We present free cash flow as a supplemental measure because we believe this measure is a financial metric used by many investors to compare valuation and liquidity measures across companies, especially in the services industry. This measure is not a recognized measure of financial performance under GAAP in the United States, and should not be considered as a substitute for operating earnings, net earnings or cash flow from operating activities, as determined in accordance with GAAP. Our method of calculating free cash flow may differ from other issuers and accordingly, this measure may not be comparable to measures used by other issuers. A reconciliation of net cash flow from operating activities to free cash flow appears below.

We use the term assets under management (“AUM”) as a measure of the scale of our Investment Management operations. AUM is defined as the gross market value of operating assets and the projected gross cost of development assets of the funds, partnerships and accounts to which we provide management and advisory services, including capital that such funds, partnerships and accounts have the right to call from investors pursuant to capital commitments. Our definition of AUM may differ from those used by other issuers and as such may not be directly comparable to similar measures used by other issuers.

We use the term fee paying assets under management (“FPAUM”) to represent only the AUM on which the Company is entitled to receive management fees. We believe this measure is useful in providing additional insight into the capital base upon which the Company earns management fees. Our definition of FPAUM may differ from those used by other issuers and as such may not be directly comparable to similar measures used by other issuers.

Risk factors

Readers should carefully consider the following risks, as well as the other information contained in this AIF and our management’s discussion and analysis for the year ended December 31, 2025. If any of the following risks actually occurs, our business could be materially harmed. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties, including those of which we are currently unaware or we currently deem immaterial, may also adversely affect our business.

Risks relating to our business

Economic conditions, especially as they relate to interest rates, credit conditions and business spending

During periods of rising interest rates, economic, fiscal or political uncertainty, market volatility, disruption to global capital or credit markets our operations may be negatively affected. Tighter credit conditions impact commercial real estate transaction volumes, which may materially reduce demand for our Capital Markets services. Continued uncertainty in the market can also impact Leasing volumes, with occupiers opting either for smaller than optimal space or shorter lease terms. Moreover, lower business spending directly impacts our Outsourcing & Advisory revenues, with some services potentially being conducted in-house. These factors could also lead to payment delays or defaults from customers, which negatively impacts our operating revenues, profitability and cash flow.

Commercial real estate property values, vacancy rates and general conditions of financial liquidity for real estate transactions

Property values have a direct impact on the commissions earned on sales transactions. Vacancy rates affect market lease rates and the duration of lease commitments, which are the basis of leasing commissions earned. Both property values and vacancy rates influence the number of sales and leasing transactions that occur, which may materially impact our revenues, financial condition, results of operations and cash flows.

Economic deterioration impacting our ability to recover goodwill and other intangible assets

Expectations of future earnings drive the recoverability of goodwill and other intangible assets, which are tested, at least, on an annual basis. A future deterioration of operating performance may necessitate non-cash impairment charges.

As a result of the changes in the current economic environment, geopolitical uncertainty, inflation and rising interest rates, management has performed asset impairment testing across our reporting units. Management has concluded that no impairment loss is required to be recognized as of December 31, 2025. The testing considered a range of scenarios, but is subject to significant estimation uncertainty given the factors noted above. If there are future adverse developments, impairment losses may be required to be recognized.

The effects of changes in foreign exchange rates in relation to the US dollar on our Euro, Canadian dollar, Australian dollar and UK pound sterling denominated revenues and expenses

We generate approximately 52% of our revenues outside the United States. Consequently, our consolidated results are impacted by fluctuations in the relative strength of the US dollar against foreign currencies, including the Euro, Canadian dollar, Australian dollar and UK pound sterling.

Any imposed tariffs can materially impact foreign exchange rates, which are closely tied to international trade flows. Moreover, political events, including elections and referenda, among other things, could also impact foreign exchange rates in relation to the US dollar. In addition, we expect to acquire additional international operations in the future. As a consequence, foreign currency exchange rate fluctuations may be material in the future.

Competition, economic conditions, and reputational risks may hamper our ability to fundraise in Investment Management

Our ability to raise capital is dependent on multiple factors, including fund performance, macroeconomic environment, and fundraising by our competitors. In certain cases, investors may decrease allocations to the asset classes we invest in, either to maintain portfolio allocations; to make a macro shift away from the asset class; or to invest in our competitors’ funds. Continued competition in the industry may also impact or ability to generate management fees and carried interest at historical levels.

Moreover, in our Investment Management operations, our reputation could be negatively impacted by various factors including poor performance; actual, potential or perceived conflicts of interest; misconduct by employees; rumors; or underperformance in our investments or strategies relative to benchmark, which may have significant impact on our fundraising initiatives.

Failure to meet threshold returns in our long-dated funds

There is no certainty that we will be able to meet contractually defined threshold returns, which are highly dependent on macroeconomic conditions and a fund’s ability to identify suitable investment opportunities. Failure to generate threshold returns could lead to lower, or the absence of, carried interest revenues, related profitability and also adversely impact our future fundraising efforts.

Seeding new funds require temporary investments which may impact liquidity

We periodically enter into arrangements to temporarily own assets on behalf of a new fund with the expectation that the assets will be subsequently transferred to the fund. However, in certain cases, we may be unable to transfer the assets to the fund and may be required to keep ownership of the assets for longer than expected. This could impact our available liquidity and potential to fund other internal or acquisition growth initiatives. A general lack of liquidity on our balance sheet could inhibit us from seeding new funds and thus limit growth in our Investment Management operations.

A decline in our ability to fundraise, or an increase in redemptions from our perpetual funds and separately managed accounts could adversely impact our Investment Management operations

The success of our Investment Management operations is dependent on our ability to fundraise. Failure to do so could severely constrain growth in our assets under management, and consequently profitability. Higher than expected redemption requests could also adversely impact management fees in our perpetual funds and separately managed accounts and may also create reputational risks which could impact subsequent fundraising efforts.

A decline in performance in our Investment Management operations

The revenue, net earnings and cash flow generated by our Investment Management operations may fluctuate, primarily due to the changes in management fees as a result of market movements from one period to another in our perpetual funds. In the event that any of the funds that we manage were to perform poorly, our revenue, net earnings and cash flow could be materially impacted. Investors and potential investors in our funds continually assess our performance, and our ability to raise capital for existing and future funds and maintaining our current fee structure will depend on our continued satisfactory performance.

Risks associated with Colliers Debt & Structured Finance operations

Our Colliers Debt & Structured Finance operations have certain key risk factors unique to the services provided, including:

Rising inflation could materially impact our profitability

In our Outsourcing & Advisory and Investment Management operations, we provide contractual services to clients, typically for multi-year durations. The contracts typically include price escalation for inflation. However, should inflation rise more than anticipated, it could severely impact our ability to recover certain cost from our clients. Moreover, compensation represents our largest expense. Rising wage costs could impact not only our profitability but also our ability to recruit and retain talent.

A decline in our ability to generate cash from our businesses to fund future acquisitions and meet our debt obligations

We rely on our businesses to generate the necessary cash to service our financial obligations. As at December 31, 2025, we have $1.43 billion of debt outstanding, net of cash, of which $542.0 million that will be required to be refinanced or repaid over the next five years. To date, we have met all of our debt obligations. However, a decline in business performance may impact our ability to service outstanding debt, and/or raise capital at favourable terms.

Competition in the markets served by the Company

We operate in highly competitive markets. Changes in the source and intensity of competition in the markets served by us impact the demand for our services and may result in additional pricing pressures. The relatively low capital cost of entry to certain of our businesses has led to strong competitive markets, including regional and local owner-operated companies. Regional and local competitors operating in a limited geographic area may have lower labour, benefits and overhead costs. The principal methods of competition in our businesses include name recognition, quality and speed of service, pricing, customer satisfaction and reputation. No assurance can be given that we will be able to compete successfully against current or future competitors and that the competitive pressures that we face will not result in reduced market share or negatively impact our financial performance.

A decline in our ability to attract, recruit and retain talent

Our ability to attract and recruit talent is an important determinant of revenue growth. While the Company makes significant efforts in attracting, recruiting and mobilizing talent, it is possible that we are unable to hire sufficiently skilled investment professionals, engineers, property managers, and real estate sales/leasing advisors, which can impact our ability to sustain or increase our internal revenue growth.

Labour shortages or increases in wage and benefit costs

As a services company, our primary asset is the human capital that comprises our workforce to generate revenues. A shortage, or increase in wage and benefit costs, of this human capital could reduce our revenues and profitability.

Reliance on subcontractors

For certain of our services, we rely on external subcontractors for timely delivery and execution. Failure to manage subcontractor performance may result in higher costs and potential loss of clients.

The effects of changes in interest rates on our cost of borrowing

The Company uses its Revolving Credit Facility and Accounts Receivable Facility, which are at variable interest rates (except for borrowings swapped to fixed), as primary sources of funding for its operations, acquisitions and other general proceeds. As a result, changes in base rates, such as SOFR, affect our interest expense as these base rates fluctuate.

A decline in our performance impacting our continued compliance with the financial covenants under our debt agreements, or our ability to negotiate a waiver of certain covenants with our lenders

A decline in our earnings performance may cause our financial leverage to increase, which results in a higher applicable margin on our Revolving Credit Facility, thereby increasing our interest costs. A decline in earnings performance may also cause us to be non-compliant with certain financial covenants, leading to a potential default on our debt obligations.

Unexpected increases in operating costs, such as insurance, workers’ compensation, and health care

As a services company, the costs of providing services to our customers can fluctuate. Certain operating costs, such as insurance, workers’ compensation and health care are based on market rates which we cannot control and, absent an offsetting price increase in our services, have a direct impact on our operating margins.

Changes in the frequency or severity of insurance incidents relative to our historical experience

Adverse changes in claims experience could increase our insurance costs and/or increase the risk of being unable to renew insurance coverage at our operations. In each of our operating segments, we effectively self-insure certain risks, with a layer of third-party insurance for catastrophic claims. An increase in the frequency or severity of claims in these areas could materially affect our financial position and results of operations. There can be no assurance that we will be able to obtain insurance coverage on favourable economic terms in the future.

A decline in the availability of suitable acquisition targets

Although the diversified professional services market remains highly fragmented, ongoing consolidation activity may limit our ability to find suitable acquisition targets. It is possible that irrational buyer behavior in the market could drive valuations higher than before, which can significantly impact our ability to close transactions on mutually favorable terms.

A decline in our ability to successfully integrate acquired operations

Failure to successfully integrate acquisitions into our existing operations can be disruptive to our business and may have a material adverse impact on our operating results. Challenges in integrating operations and information technology systems acquired from other companies may also limit our ability to achieve anticipated synergies. We may experience difficulties in the assimilation of different cultures and practices, integration of systems, including accounting systems, as well as in maintaining controls, including internal control over financial reporting required by applicable securities laws and related procedures and policies. It is possible that the integration process could result in a loss of key management personnel and clients, which can severely impact profitability. In addition, we may also expose ourselves to unforeseen liabilities which may have not been identified during the due diligence process.

Changes in laws, regulations and government policies at the federal, state/provincial or local level that may adversely impact our businesses

As a multinational company, changes in laws and regulation at the different jurisdictional levels can have a direct effect on our operations. It is difficult to predict the future impact of a change in legislative and regulatory requirements affecting our businesses. The laws and regulations applicable to our businesses will likely change in the future and affect our operations and financial performance. In addition, if we were to fail to comply with any applicable law or regulation, we could be subject to substantial fines or damages, be involved in litigation, suffer losses to our reputation and suffer the loss of licenses or penalties that may affect how our business is operated, which, in turn, would have a material adverse effect on our business, financial condition and results of operations.

Risks arising from any regulatory review and litigation

The commencement of any formal regulatory reviews or investigations could result in the diversion of significant management attention and resources and, if securities or other regulators determine that a violation of securities or other laws may have occurred, or has occurred, the Company or its officers and directors may receive notices regarding potential enforcement action or prosecution and could be subject to civil or criminal penalties or other remedies. For example, the Company or its officers could be required to pay substantial damages, fines or other penalties, the regulators could seek an injunction against the Company or seek to ban an officer or director of the Company from acting as such, any of which actions would have a material adverse effect on the Company.

Risks associated with intellectual property and other proprietary rights that are material to our business

Our ability to compete effectively depends in part on our rights to service marks, trademarks, trade names and other intellectual property rights we own or license (including “Colliers”). We have not sought to register every one of our marks in every country in which they are used. Furthermore, because of the differences in foreign trademark, patent and other intellectual property or proprietary rights laws, we may not receive the same protection in other countries as we would in Canada or the United States. If we are unable to protect our proprietary information and brand names, we could suffer a material adverse effect on our business, financial condition or results of operations. Litigation may be necessary to enforce our intellectual property rights and protect our proprietary information, or to defend against claims by third parties that our products or services infringe their intellectual property rights. Any litigation or claims brought by or against us could result in substantial costs and diversion of our resources. A successful claim of trademark, patent or other intellectual property infringement against us, or any other successful challenge to the use of our intellectual property, could subject us to damages or prevent us from providing certain services under our recognized brand names, which could have a material adverse effect on our business, financial condition or results of operations.

Reputational risk

The Company operates in multiple global jurisdictions and is subject to various local laws and regulations. We train employees to comply with anti-bribery and workplace violence and harassment laws along with clear company-wide guidelines, internal controls and policies in place to prohibit any non-compliant behaviours. However, despite our best efforts, it is possible that violations may occur, either through our own employees or through our external partners/subcontractors, which may expose the Company to potential litigation and lawsuits and significantly harm our reputation. Reputational losses may also arise from any negative publicity, failure to meet client expectations and negative market perception.

Disruptions or security failures in our data governance

Our information technology systems facilitate our ability to monitor, operate and control our operations. While we have disaster recovery plans in place, any disruption in these plans or the failure of our data governance to operate as expected could, depending on the magnitude of the problem, adversely affect our operating results by limiting, among other things, our capacity to monitor, operate and control our operations effectively. In addition, because our systems contain information about individuals and businesses, our failure to maintain the security of the data we hold, whether the result of our own error or the malfeasance or errors of others, could harm our reputation or give rise to legal liabilities relating to violations of privacy laws or otherwise, which may lead to lower revenues, increased costs and other material adverse effects on our results of operations.

Cybersecurity risks

Cybersecurity incidents, in the form of malware, computer viruses, cyber threats, malfeasance and other types of data breaches, continue to rise. With our employees relying heavily on our information systems, some managed by third parties, we make significant efforts to maintain the security of our information systems as well as to monitor for cybersecurity threats. However, there can be no assurance that we will be able to prevent all cybersecurity incidents, which could have a material adverse impact on our operations. This could be in the form of lost revenues, unauthorized access to client and employee data, damage to our reputation, significant corrective costs and as well as material legal liabilities.

Risks associated with artificial intelligence, machine learning and other emerging technology

We are increasingly utilizing artificial intelligence (AI) and machine learning technologies to enhance our service offerings, improve operational efficiency, and gain strategic insights. However, our adoption and use of AI present a number of risks to our business, operations, and financial performance.

The rapid evolution of AI technologies may intensify our exposure to cybersecurity threats, including sophisticated data breaches and cyber-attacks. The data used to train and operate our AI models could be targeted, and any failure to protect the security and privacy of our client and corporate data could result in financial liability, regulatory penalties, and reputational harm.

Our AI systems may produce inaccurate, biased, or flawed outputs, or they may be misused, which could lead to poor business decisions, financial loss, or damage to our brand and client relationships. Furthermore, the successful implementation of our AI strategy is highly dependent on our ability to attract, train, and retain a sufficient number of employees with specialized skills in AI and data science. Increased competition for this talent could adversely affect our ability to innovate and execute our business strategy.

The legal and regulatory landscape governing AI is uncertain and rapidly evolving. Changes in laws or the interpretation of existing regulations could increase our compliance costs, limit our ability to use AI, or subject us to unforeseen liabilities. If we fail to effectively navigate these risks or keep pace with our competitors' advancements in AI, our business, financial condition, and results of operations could be materially adversely affected.

Our competitors or other third parties may incorporate AI into their product and service offerings more quickly or more successfully than us, which could impair our ability to compete effectively and adversely affect our business, financial condition and results of operations.

Exposure to global tax laws

Given our global footprint, we are subject to income tax laws in various jurisdictions. While we continuously manage and provision for income tax, any changes in effective tax rates within local jurisdictions can have a material impact on our net earnings.

Political conditions or events, including escalation of hostilities, outbreak of war, elections, referenda, changes to international trade and immigration policies, terrorism, disruption of supply chains (particularly energy) and the impact thereof on our business

Political events, uncertainties and situations can have an effect on our Company because of our global operations. Events could occur that may hamper our ability to manage operations, repatriate cash and implement Colliers’ policies in certain regions, particularly in developing countries that have had a recent history of political and economic instability.

Risks relating to our shares

Volatility of market price of the Subordinate Voting Shares

The market price of the Subordinate Voting Shares may be volatile and subject to wide fluctuations in response to numerous factors, many of which are beyond our control, including the following:

The volatility may affect the ability of holders of Subordinate Voting Shares to sell the Subordinate Voting Shares at an advantageous price.

Financial markets have, at times, experienced significant price and volume fluctuations that have particularly affected the market prices of securities of companies and that have, in many cases, been unrelated to the operating performance, underlying asset values or prospects of such companies. Accordingly, the market price of the Subordinate Voting Shares may decline even if our operating results, underlying asset values or prospects have not changed. Additionally, these factors, as well as other related factors, may cause decreases in asset values that are deemed to be other than temporary, which may result in impairment losses. As well, certain institutional investors may base their investment decisions on consideration of our environmental, governance and social practices and performance against such institutions’ respective investment guidelines and criteria, and failure to meet such criteria may result in a limited or no investment in the Subordinate Voting Shares by those institutions, which could adversely affect the trading price of the Subordinate Voting Shares. There can be no assurance that fluctuations in price and volume will not occur. If such increased levels of volatility and market turmoil occur, our operations could be adversely impacted and the trading price of the Subordinate Voting Shares may be adversely affected.

The impact of our dual class share structure

As agreed in the New Trust Agreement, the Multiple Voting Shares shall convert on a one-for-one basis into Subordinate Voting Shares upon the occurrence of certain specified events and in any event by not later than September 1, 2028. However, the Multiple Voting Shares shall remain issued and outstanding until any such conversion event. Our Multiple Voting Shares have twenty votes per share and our Subordinate Voting Shares have one vote per share. As at February 20, 2026, Mr. Hennick beneficially owns and controls all of the Multiple Voting Shares, and holds approximately 41.6% of the voting power of all of our issued and outstanding Subordinate Voting Shares and Multiple Voting Shares and therefore has significant influence over our management and affairs and over all matters requiring shareholder approval, including the election of directors and significant corporate transactions. As a result, the holder of Multiple Voting Shares has the ability to influence many matters affecting us and actions may be taken that the holders of the Subordinate Voting Shares may not view as beneficial. The market price of the Subordinate Voting Shares could be adversely affected due to the significant influence and voting power of the holder of Multiple Voting Shares. Additionally, the significant voting interest of the holder of Multiple Voting Shares may discourage transactions involving a change of control, including transactions in which an investor, as a holder of the Subordinate Voting Shares, might otherwise receive a premium for the Subordinate Voting Shares over the then-current market price, or discourage competing proposals if a going private transaction is proposed by the holder of Multiple Voting Shares.

A decline in our performance impacting our ability to pay dividends on our shares

Although we intend to make cash dividends to shareholders in accordance with our existing dividend policy, these dividends are not assured. Future dividends on the Subordinate Voting Shares and Multiple Voting Shares will depend on our results of operations, financial condition, capital requirements, general business conditions and other factors that our board of directors may deem relevant. Additionally, under the Company’s debt agreements, the Company is not permitted to pay dividends, whether in cash or in specie, in the circumstances of an event of default thereunder occurring and continuing or an event of default occurring as a consequence thereof. The market value of the Subordinate Voting Shares and Multiple Voting Shares may deteriorate if we are unable to pay dividends pursuant to our existing dividend policy in the future.

Potential future dilution to the holders of the Subordinate Voting Shares

We are authorized to issue an unlimited number of Subordinate Voting Shares for consideration and terms and conditions as established by our board of directors, in many cases, without any requirement for explicit shareholder approval, and shareholders have no pre-emptive rights in connection with such further issuances. We may issue additional Subordinate Voting Shares in share offerings (including through the sale of securities convertible into or exchangeable for Subordinate Voting Shares) and pursuant to the exercise of options under our Option Plan. We cannot predict the size of future issuances of Subordinate Voting Shares or the effect that future issuances and sales of Subordinate Voting Shares will have on the market price of the Subordinate Voting Shares. Issuances of a substantial number of additional Subordinate Voting Shares, or the perception that such issuances could occur, may adversely affect prevailing market prices for the Subordinate Voting Shares. With any additional issuance of Subordinate Voting Shares, holders of Subordinate Voting Shares will suffer dilution and we may experience dilution in our earnings per share.

The existence of our right to issue blank cheque preference shares

The Company has the right to issue so-called “blank cheque” preference shares which may affect the voting and liquidation rights of holders of Subordinate Voting Shares and Multiple Voting Shares. The Company’s Board of Directors is authorized, without any further shareholder approval, to issue one or more additional series of preference shares in an unlimited number and to set the rights, privileges, restrictions and conditions attached thereto.

Risks related to our qualification as a foreign private issuer

We are a “foreign private issuer”, as such term is defined in Rule 405 under the United States Securities Act of 1933, as amended, and are permitted, under a multijurisdictional disclosure system adopted by the United States and Canada, to prepare our disclosure documents filed under the United States Securities Exchange Act of 1934, as amended (“US Exchange Act”), in accordance with Canadian disclosure requirements. Under the US Exchange Act, we are subject to reporting obligations that, in certain respects, are less detailed and less frequent than those of US domestic reporting companies. As a result, we do not file the same reports that a US domestic issuer would file with the Securities and Exchange Commission (“SEC”), although we are required to file or furnish to the SEC the continuous disclosure documents that we are required to file in Canada under Canadian securities laws. In addition, our officers, directors, and principal shareholders are exempt from the reporting and short swing profit liability provisions of Section 16 of the US Exchange Act. Therefore, our shareholders may not know on a timely basis when our officers, directors and principal shareholders purchase or sell shares, as the reporting deadlines under the corresponding Canadian insider reporting requirements are generally longer.

As a foreign private issuer, we are exempt from the rules and regulations under the US Exchange Act related to the furnishing and content of proxy statements. We are also exempt from Regulation FD, which prohibits issuers from making selective disclosures of material non-public information. While we will comply with the corresponding requirements relating to proxy statements and disclosure of material non-public information under Canadian securities laws, these requirements differ from those under the US Exchange Act and Regulation FD, and shareholders should not expect to receive the same information at the same time as such information is provided by US domestic companies.

In addition, as a foreign private issuer, we have the option to follow certain Canadian corporate governance practices, except to the extent that such laws would be contrary to US securities laws, and provided that we disclose the requirements we are not following and describe the Canadian practices we follow instead. We currently rely on this exemption with respect to requirements regarding the quorum for any meeting of our shareholders, the requirement to obtain shareholder approval prior to an issuance of securities in certain circumstances and certain responsibilities of the Executive Compensation Committee of our board of directors. We may in the future elect to follow home country practices in Canada with regard to other matters. As a result, our shareholders may not have the same protections afforded to shareholders of US domestic companies that are subject to all corporate governance requirements.

Risks relating to sustainability

Risks related to global climate change

As global climate change policy continues to evolve and attract considerable public, scientific and regulatory attention, it could have both tangible and intangible impact on our operations, employees and clients. Moreover, we may be subject to litigation on certain properties, projects or assets that we manage that have a direct impact on the environment from governments, shareholders and environmental activists. A loss of management fee revenues as well as any litigation could materially impact our profitability, reputation as well as financial condition.

Changes in client preferences and requirements for low-carbon and climate-resilient properties

As climate policy continues to evolve and demand for low-carbon and climate-resilient properties increases, it may impact our operations with respect to deal sourcing as well as product availability. Should the company be unable to meet client needs, it may also lead to deterioration of relationship with the client and a loss of revenue.

Reputational risk should our efforts to mitigate climate change not keep pace with peers and societal expectations

We are making dedicated efforts towards reducing our carbon footprint, promoting social initiatives and implementing strong governance policies. However, there can be no assurance that we will be able to achieve all of our targets. In the unlikely event of the Company failing to meet its target or falling short of societal expectations, there could be a material adverse impact on our operations. This could be in the form of lost revenues, damage to our reputation, decreased attractiveness to investors, as well as significant operating costs.

Risks related to measurement and compliance

We need to invest in various technologies to accurately manage and comply with the environmental regulatory policies of the local and global jurisdictions. In addition, in certain cases, we may purchase carbon offsets or could be exposed to carbon tax on our owned operations. Compliance costs, in some regions, could also force us to discontinue managing certain properties or exit the business altogether. This could lead to a significant deterioration in profitability.

Physical and transition risks related to climate-related changes

Rapid changes in client preferences and requirements for low-carbon and climate-resilient properties, ahead of our ability to deliver related solutions, could lead to customer attrition and consequently lower revenues and profitability. Our operating costs could also increase marginally with increasing carbon pricing, should we fail to transition our operations to lower-carbon energy sources in time. Lastly, our invested assets in our Investment Management business and the properties we manage are susceptible to physical damages due to climate-related changes.

Interest of management and others in material transactions

Except as described below or elsewhere in this AIF, no director of Colliers, executive officer of Colliers, or person or company that beneficially owns, or controls or directs more than 10% of any class or series of voting securities of Colliers, or any associate or affiliate of any of the foregoing persons, has or has had any material interest in any transaction within the last three years, or during the current year, that has materially affected or is reasonably expected to materially affect Colliers or any of its subsidiaries.

On April 16, 2021, the Company completed a transaction with Mr. Hennick and certain related entities pursuant to which: (a) the LTIA that had been previously granted to Mr. Hennick was terminated, for effective consideration of $96.2 million and the issuance of 3,572,858 Subordinate Voting Shares (such consideration having been determined with reference to the formula set out in the previously issued LTIA); (b) Mr. Hennick and certain related entities entered into the New MSA with respect to the provision of Mr. Hennick’s services as Chief Executive Officer and/or Executive Chairman of the Company, as his option; and (c) the New Trust Agreement was entered into, resulting in a clear timeline for the orderly elimination of the Subordinate Voting Shares and the Company’s dual class share structure, without payment of any premium. Full details regarding this transaction are set out in the Management Information Circular of the Company dated March 9, 2021, which is available on SEDAR+ at www.sedarplus.ca.

Material contracts

The only contracts that can reasonably be regarded as material to us, other than contracts entered into in the ordinary course of business, are as follows:

Cease trade orders, bankruptcies, penalties or sanctions

To the best of the knowledge of the Company:

except for Benjamin Stein, who served as a director of GTT Communications, Inc. (“GTT”) from May 2019 until December 2021. GTT commenced Chapter 11 bankruptcy proceedings in the United States in October 2021 which were subsequently completed in December 2022.

Conflicts of interest

Certain directors and officers of the Company are engaged in and will continue to engage in activities outside the Company, and as a result, certain directors and officers of the Company may become subject to conflicts of interest. The Business Corporations Act (Ontario) provides that in the event that a director or officer has an interest in a contract or proposed contract or agreement, the director or officer shall disclose his or her interest in such contract or agreement and, in the case of directors, shall refrain from voting on any matter in respect of such contract or agreement unless otherwise provided under the Business Corporations Act (Ontario). To the extent that conflicts of interest arise, such conflicts will be resolved in accordance with the provisions of the Business Corporations Act (Ontario).

As at the date hereof, the Company is not aware of any existing or potential material conflicts of interest between the Company and a director or officer of the Company.

Independent registered public accounting firm

The Company’s independent registered public accounting firm is PricewaterhouseCoopers LLP, Chartered Professional Accountants, who has issued a Report of Independent Registered Public Accounting Firm dated February 20, 2026 on the Company’s consolidated financial statements as of December 31, 2025 and 2024 and for each of the years in the two-year period ended December 31, 2025 and on the effectiveness of the Company’s internal control over financial reporting as at December 31, 2025. PricewaterhouseCoopers LLP has advised that they are independent with respect to the Company within the meaning of the Chartered Professional Accountants of Ontario CPA Code of Professional Conduct and the rules and regulations of the SEC and the Public Company Accounting Oversight Board (“PCAOB”).

Audit & Risk Committee

The Audit & Risk Committee (the “ARC”) is comprised of three members who are each “independent” and “financially literate” as required by Multilateral Instrument 52-110 Audit Committees (the “Audit Committee Rule”). The ARC has the resources and the authority to discharge its responsibilities, including the authority to engage, at the expense of Colliers, outside consultants, independent legal counsel and other advisors as it determines necessary to carry out its duties, without seeking approval our Board of Directors or management. The ARC also has the authority to conduct any investigation necessary and appropriate to fulfilling its responsibilities and has direct access and authority to communicate directly with the external auditors, legal counsel and officers and employees of Colliers. The ARC meets six times annually, or more frequently as circumstances dictate.

The ARC reviews the annual and interim financial statements intended for circulation among shareholders and reports upon these to the Board prior to their approval by our Board of Directors. The ARC is also responsible for reviewing the integrity of Colliers’ financial reporting process, both internal and external, and any major issues as to the adequacy of the internal controls and any special audit procedures adopted in light of any material control deficiencies. The ARC communicates directly with Colliers’ external auditors in order to discuss audit and related matters whenever appropriate. In addition, our Board of Directors may refer to the ARC such matters and questions relating to the financial position and operations of Colliers and its subsidiaries. All reports made to Colliers’ ethics hotline are reviewed by the Chair of the ARC and then by the entire ARC at its next meeting. Our Board of Directors has adopted an ARC mandate, a copy of which is annexed as Exhibit “A” to this AIF.

The education and related experience of each of the members of the ARC that is relevant to the performance by such members of their responsibilities on such committee is described below.

EXHIBIT “A”

AUDIT & RISK COMMITTEE MANDATE

Purpose

The Audit & Risk Committee (the "Committee") is appointed by and shall assist the Board of Directors (the "Board") of Colliers International Group Inc. (the "Company") in fulfilling its oversight responsibilities in the following principal areas: (i) accounting policies and practices, (ii) the financial reporting process, (iii) financial statements provided by the Company to the public, (iv) risk identification, management and processes, including systems of internal accounting and financial controls, internal systems reviews and remediation, information technology and cyber-security risks and controls, (v) reviewing the Company's insurance policies and consideration of the extent of any uninsured exposure and the adequacy of coverage, (vi) appointing, overseeing and evaluating the work and independence of the external auditors and overseeing and evaluating the work of the Company's internal audit personnel (including by way of regular interaction and review at all Committee meetings and periodic meetings with the Company’s Director of Internal Audit at in camera sessions), (vii) compliance with applicable legal and regulatory requirements (including the Sarbanes-Oxley Act of 2002 and all applicable laws relating to environmental, social and governance matters), (viii) review of contractual arrangements involving related parties, conflicts of interest or material risks (other than employment related contracts), and (ix) overseeing and evaluating compliance with the Company's Code of Ethics and Conduct, Ethics Hotline Policy and other Company policies involving ethics and/or conflicts of interest. In addition to the responsibilities specifically enumerated in this Mandate, the Board may refer to the Committee such matters and questions relating to the financial position and operations of the Company and its subsidiaries as the Board may from time to time see fit.

Membership

The Committee shall consist of at least three directors appointed annually by the Board and shall be selected based upon the following, in accordance with applicable laws, rules and regulations:

Independence. Each member shall be independent in accordance with applicable legal and regulatory requirements, including, without limitation, the independence requirements set forth in Rule 10A-3(b)(1) under the Securities Exchange Act of 1934, as amended (the “Act”) (subject to the exemptions provided in Rule 10A-3(c) under the Act) and National Instrument 52-110 – Audit Committees of the Canadian Securities Administrators, and shall have no direct or indirect material relationship with the Company which could, in the view of the Board, reasonably interfere with the exercise of a member's independent judgment.

Financially Literate. Each member shall be financially literate or must become financially literate within a reasonable period of time after his or her appointment to the Committee. For these purposes, an individual is financially literate if he or she has the ability to read and understand a set of financial statements that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of the issues that can reasonably be expected to be raised by the Company's financial statements.

Commitment. In addition to being a member of the Committee, if a member is also on the audit committee or board of directors of other public companies or organizations, the Board shall determine that such simultaneous service does not impair the ability of such member to serve effectively on the Committee.

Chair and Secretary

The Chair of the Committee shall be selected by the Board. If the Chair is not present, the members of the Committee may designate a Chair for the meeting by majority vote of the members present. The Secretary of the Company shall be the Secretary of the Committee, provided that if the Secretary is not present, the Chair of the meeting may appoint a secretary for the meeting with the consent of the other Committee members who are present.

Meetings

The times and locations of meetings of the Committee and the calling of and procedures at such meetings, shall be determined from time to time by the Chair of the Committee, in consultation with management when necessary, provided that there shall be a minimum of four meetings per year. The Committee shall have sufficient notice in order to prepare for each meeting. Notice of each meeting shall also be given to the external auditors of the Company, and meetings shall be convened whenever requested by the external auditors or any member of the Committee in accordance with applicable law.

Meeting Agendas

Agendas for meetings of the Committee shall be developed by the Chair of the Committee in consultation with management and the corporate secretary, and shall be circulated to the Committee members prior to any meetings.
