Colliers (NASDAQ: CIGI) lifts Q1 revenue 15% and plans $700M Ayesa deal

Rhea-AI Filing Summary

Colliers International Group Inc. reported first-quarter 2026 revenue of $1.31 billion, up 15% year over year (12% in local currency), driven by 7% internal growth and recent acquisitions. GAAP diluted net loss per share widened to $(0.47) from $(0.08), mainly due to a larger non-controlling interest redemption increment, higher acquisition-related expenses, and higher income taxes.

Adjusted EPS rose modestly to $0.91 from $0.87, and Adjusted EBITDA increased to $124.8 million from $116.0 million as higher revenue and equity earnings offset increased investment spending. Commercial Real Estate revenue grew 14% to $841.2 million, with Capital Markets up 47% and Leasing up 11%. Engineering revenue rose 23% to $336.8 million, and Investment Management revenue grew 7% to $135.3 million, though segment Adjusted EBITDA declined on planned growth investments.

Colliers agreed to acquire Ayesa Engineering for about $700 million, with expected closing in Q2 2026, and issued C$550 million of 4.73% senior notes due 2033 while extending its $2.25 billion revolving credit facility to 2031. Net cash used in operating activities was $187.4 million, reflecting seasonal working-capital outflows, and net indebtedness was $1.67 billion with a leverage ratio of 2.3x and $1.30 billion of undrawn revolver capacity. Management reiterated its 2026 outlook for mid-teens percentage growth in revenue, Adjusted EBITDA and Adjusted EPS, including the anticipated Ayesa closing.

Insights

Equity research analyst

Colliers posts solid Q1 revenue growth and funds a major engineering acquisition while leverage remains moderate.

Colliers delivered Q1 2026 revenue of $1.31 billion, up 15%, with both Commercial Real Estate and Engineering contributing double-digit growth. Adjusted EBITDA rose to $124.8 million, although the margin eased to 9.5% as the company increased investment, particularly in Investment Management.

GAAP results showed a diluted loss of $(0.47) per share, driven mainly by a higher non-controlling interest redemption increment, acquisition-related costs and a 43.4% effective tax rate. Adjusted EPS still improved slightly to $0.91, reflecting underlying earnings resilience despite these non-operating and non-cash items.

Strategically, Colliers agreed to acquire Ayesa Engineering for about $700 million, after Ayesa generated roughly $370 million of 2025 revenue. The company supported this expansion by placing C$550 million of 4.73% senior notes due 2033 and extending its $2.25 billion revolver to 2031. Net debt of $1.67 billion and a 2.3x leverage ratio sit below the covenant ceiling, and the revolver now includes a temporary step-up mechanism to 4.0x following large deals, providing additional headroom.

6 terms

Adjusted EBITDA financial

"Adjusted EBITDA of $124.8 million was up 8% versus $116.0 million"

Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.

Adjusted EPS financial

"Adjusted earnings per share (see “Reconciliation of non-GAAP financial measures” below) were $0.91"

Adjusted earnings per share (adjusted eps) is a measure of a company's profit per share that has been modified to exclude certain one-time or unusual items, such as costs from restructuring or asset sales. It provides a clearer picture of the company’s core performance by removing events that may distort the usual earnings. Investors use adjusted eps to better understand a company's ongoing profitability and compare it more accurately over time.

redeemable non-controlling interests financial

"The minority equity positions in the Company’s subsidiaries are referred to as redeemable non-controlling interests (“RNCI”)."

Redeemable non-controlling interests are ownership stakes in a company’s unit held by outside investors that can be forced to be bought back by the parent company for cash or a set value. Think of it like a part-owner who has the contractual right to ‘cash out’ their share; for investors this matters because it can create a future cash obligation, change reported equity versus debt, and affect earnings and ownership percentages.

AR Facility financial

"Under the accounts receivable facility (the “ Facility”), certain of the Company's subsidiaries continuously sell trade accounts receivable"

Science-Based Targets initiative financial

"For 2025, the target was to reduce greenhouse gas emissions consistent with the Science-Based Targets initiative."

An organization that helps companies set greenhouse gas reduction goals that align with climate science and the limits needed to avoid dangerous warming. For investors, a company with these validated targets is like a traveler following a reliable map: it signals a clear plan to cut emissions, lower regulatory and physical climate risks, and improve long-term resilience and credibility, which can affect valuations, access to capital, and reputation.

cash flow hedges financial

"All interest rate swaps list in the table above ... are being accounted for as cash flow hedges"

A cash flow hedge is an accounting label companies use when they enter financial contracts—like currency or interest-rate agreements—to protect expected future cash payments or receipts from unpredictable moves. For investors, it signals that the company is trying to smooth out future cash variability (think of locking in a price to avoid surprises), which can reduce reported profit swings but also means the company has exposure to derivative instruments and their associated risks.

Colliers International Group Inc.

Notes to Consolidated Financial Statements

(in thousands of US dollars, except share and per share amounts)

1. Description of the business

Colliers International Group Inc. (“Colliers” or the “Company”) is a global diversified professional services and investment management company providing services to corporate and institutional clients in 33 countries around the world (70 countries including affiliates and franchisees). Operationally, Colliers is organized into three distinct segments: Commercial Real Estate, Engineering and Investment Management (“IM”).

2. Summary of presentation

These unaudited Interim Consolidated Financial Statements (the “Financial Statements”) have been prepared by the Company in accordance with disclosure requirements for the presentation of interim financial information. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles (“GAAP”) in the United States of America have been condensed or omitted in accordance with such disclosure requirements. These Financial Statements should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, 2025.

These Financial Statements follow the same accounting policies as the most recent audited consolidated financial statements, except as noted below:

Change to reportable segments

The Company has realigned its Commercial Real Estate and Engineering segments to reflect the new management reporting lines into the Chief Operating Decision Maker (“CODM”) effective in the first quarter of 2026. Accordingly, the project management operations, which primarily serve leasing and occupier clients, are now reported to the CODM within the Commercial Real Estate segment for all periods presented. Commencing in the first quarter of 2026, the CODM reviews financial information and evaluates the overall business on this revised basis. The project management operations previously included in the Engineering segment represent approximately 14% of the Commercial Real Estate segment’s revenue for the three months ended March 31, 2025.

Prior year segment comparatives have been recast to reflect this change to reportable segments. The Investment Management reportable segment remains unchanged.

Goodwill

In conjunction with the changes in financial information reviewed by the CODM, the Company reassessed its reporting units and reassigned goodwill to reflect the updated segment structure using a relative fair value approach. The change in reporting units is not considered a triggering event for goodwill impairment testing as the excess fair value over carrying value of the affected reporting units substantially exceeds the goodwill reallocation.

In the opinion of management, the Financial Statements contain all adjustments necessary to a fair statement of the financial position of the Company as at March 31, 2026 and the results of operations and its cash flows for the three months ended March 31, 2026 and 2025. All such adjustments are of a normal recurring nature. The results of operations for the three-month period ended March 31, 2026, are not necessarily indicative of the results to be expected for the year ending December 31, 2026.

3. Impact of recently issued accounting standards

Recently adopted accounting guidance

Financial Instruments-Credit Losses for Accounts Receivable and Contract Assets

In July 2025, FASB issued ASU 2025-05, Financial Instruments: Credit Losses (Topic 326) which provides a practical expedient that permits entities to assume that current economic conditions will persist over the remaining life of current accounts receivable and contract assets when developing forecasts used to estimate expected credit losses. The amendments are effective for fiscal years and interim periods beginning after December 15, 2025. The Company adopted the ASU prospectively in the current annual financial statements. The adoption did not have a material impact on the Company's consolidated financial statements and related disclosures.

Recently issued accounting guidance, not yet adopted

Reporting Comprehensive Income – Expense Disaggregation Disclosures

In November 2024, FASB issued ASU No. 2024-03 Expense Disaggregation Disclosures which requires disaggregated disclosure of income statement expenses. The ASU does not require changes to the expense captions an entity presents on the face of the income statement, rather, it requires disaggregation of certain expense captions within the footnotes to the financial statements. This ASU is effective for annual periods beginning after December 15, 2026 with early adoption permitted. The Company is currently assessing the impacts of this ASU on its disclosures.

Improvements to the Accounting for Internal-Use Software

In September 2025, FASB issued ASU No. 2025-06 Targeted Improvements to the Accounting for Internal-Use Software. The amendments in this update accommodates changes to software development approaches by removing reference to development stages and requiring the capitalization of software costs when both i) management has authorized and committed funding a software project, and ii) when it is probable that the project will be completed and used to perform the function intended. The improvements will provide for greater consistency in capitalization of development costs as they relate to internal-use software. The amendments are effective for annual periods beginning after December 15, 2027, with early adoption permitted at the beginning of an annual reporting period. The Company is currently assessing the impacts of this ASU on its financial statements.

During the three months ended March 31, 2026, the Company acquired controlling interests in six businesses, one in Commercial Real Estate and five in Engineering.

Commercial Real Estate

The Company acquired a controlling interest in Colliers Progedil S.r.l., a full-service project marketing business in Italy.

Engineering

The Company closed five tuck-in acquisitions of engineering and design firms, three in Canada (BESTECH Canada Limited, Tetranex Solutions Inc. and Applied Aquatic Research Ltd.), one in the United States (Ramos Consulting Services, Inc.) and one in Australia (LocationiQ).

The acquisition date fair values of consideration transferred in relation to these acquisitions consisted of $45,042 in cash (net of cash acquired of $4,822), $2,890 in subsidiary equity consideration and $17,404 of deferred consideration. The Company acquired $9,162 of net assets, excluding cash and recognized goodwill of $29,142 and finite life intangible assets of $35,215. The Company also recognized redeemable non-controlling interest of $2,247 and deferred income tax of $5,936 on the consolidated balance sheets.

As of March 31, 2026, the Company has not completed its analysis to assign fair values to all identifiable tangible and intangible assets acquired in 2026, therefore, the purchase price allocations for the acquired businesses are provisional and subject to change within the respective measurement period which will not extend beyond one year from the acquisition date.

Page 9 of 24

During three months ended March 31, 2026, the Company made no significant adjustments to the provisional fair values allocated to acquired assets and liabilities for acquisitions completed in 2025.

The purchase price allocation of acquisitions result in the recognition of goodwill. The primary factors contributing to goodwill acquired in the three months ended March 31, 2026 are assembled workforces, synergies with existing operations and future growth prospects. Specifically, the synergies in the Company’s acquisitions primarily relate to diversifying the Company’s client base and service offerings, cross-sell opportunities, increasing market share, and geographic expansion. Future growth prospects in the acquired businesses are consistent with long-term growth trends in the commercial real estate services and engineering businesses. For acquisitions completed during the three months ended March 31, 2026, goodwill in the amount of $8,987 is deductible for income tax purposes.

2025 acquisitions

During the three months ended March 31, 2025, the Company acquired one business in Engineering. The acquisition date fair value of consideration transferred consisted of $9,485 in cash (net of cash acquired of $2,164).

Deferred acquisition consideration

Deferred acquisition consideration refers to a portion of the purchase price where payment is a fixed amount determined at the acquisition date but where payment is deferred until a future date ranging from one to ten years following the dates of the acquisition. The present value of the deferred consideration recorded on the balance sheet as at March 31, 2026, was $41,296 (December 31, 2025 - $23,356).

Contingent acquisition consideration

The Company typically structures its business acquisitions to include deferred consideration which is typically subject to contingencies. Certain vendors, at the time of acquisition, are entitled to receive a contingent consideration payment if the acquired businesses achieve specified earnings levels during the one- to five-year periods following the dates of acquisition. The ultimate amount of payment is determined based on a formula, the key inputs to which are (i) a contractually agreed maximum payment; (ii) a contractually specified earnings level and (iii) the actual earnings for the contingency period. If the acquired business does not achieve the specified earnings level, the maximum payment is reduced for any shortfall, potentially to nil.

Unless it contains an element of compensation, contingent consideration is recorded at fair value each reporting period. The fair value recorded on the consolidated balance sheet as at March 31, 2026, was $9,672 (December 31, 2025 - $8,533). See note 17 for discussion on the fair value of contingent consideration. Contingent consideration where the seller is required to remain employed to be entitled to payment is considered to have a compensatory element and is revalued at each reporting period and recognized on a straight-line basis over the term of the contingent consideration arrangement. The liability recorded on the balance sheet for the compensatory element of contingent consideration arrangements as at March 31, 2026, was $33,791 (December 31, 2025 - $33,259). The estimated range of outcomes (undiscounted) for all contingent consideration arrangements, including those with an element of compensation is determined based on the likelihood of achieving specified earnings levels over the contingency period, and ranges from an estimated $79,523 to a maximum contractual amount of $351,782. These contingencies will expire during the period extending to August 2030.

5. Business disposals

During the three months ended March 31, 2026, the Company sold two Commercial Real Estate operations, (i) a portion of its operations in Belgium and (ii) its operations in Peru. Concurrent with the disposal of Peru, the purchaser entered into an agreement to use the Colliers brand in Peru going forward. The net proceeds received on disposal were $201 and the Company recognized a loss of $531.

6. Warehouse fund assets

During the three months ended March 31, 2026, the Company did not divest any Investment Management warehouse fund assets which were held on December 31, 2025. There was no significant impact on net earnings related to warehouse fund assets in the three months ended March 31, 2026, or 2025.

The MSR assets are evaluated quarterly for impairment by stratifying the servicing portfolio according to predominant risk characteristics, primarily investor type and interest rate. An impairment is recorded if the carrying value of an individual stratum exceeds its estimated fair value. There was no impairment recorded in the three months ended March 31, 2026, or 2025.

The following table summarizes activity related to the Company’s mortgage servicing rights for the three months ended March 31, 2026:

9. Long-term debt

On February 20, 2026 the Company amended and extended the multi-currency, sustainability-linked senior unsecured revolving credit facility (the “Revolving Credit Facility”). The Revolving Credit Facility remains at $2,250,000 and the final maturity date was extended to February 20, 2031. The amendment provides for a temporary step-up to the financial leverage ratio from 3.5x to 4.0x for up to four consecutive quarters following the completion of an acquisition where the purchase price exceeds $200,000. After the four quarters, the maximum allowable leverage ratio returns to 3.5x. The Revolving Credit Facility bears interest at an applicable margin of 1.125% to 2.5% over floating reference rates, depending on financial leverage ratios. The applicable margin may be adjusted, annually, plus or minus 0.05% subject to achieving certain sustainability metrics. For the three months ended March 31, 2026, the weighted average interest rate on borrowings under the Revolving Credit Facility was 5.3% (2025 – 6.3%). The Revolving Credit Facility had $1,297,589 of available undrawn credit as at March 31, 2026 ($1,159,419 as at December 31, 2025). As at March 31, 2026, letters of credit in the amount of $28,566 were outstanding against the Revolving Credit Facility ($18,324 as at December 31, 2025). The Revolving Credit Facility requires a commitment fee of 0.11% to 0.35% of the unused portion, depending on financial leverage ratios.

The Company has outstanding senior unsecured notes (“Senior Notes”) with a carrying value of $928,300. A summary of the unsecured senior notes is provided in the table below:

				Maturity						Interest
		Term		Date		Carrying Value				Fixed Rate
Senior Notes due 2028 - €210,000		10-year		May 30, 2028		$	241,962				2.23	%
Senior Notes due 2031 - €125,000		10-year		October 7, 2031			143,954				1.52	%
Senior Notes due 2031 - $150,000		10-year		October 7, 2031			149,439				3.02	%
Senior Notes due 2033 - C$550,000		7-year		April 7, 2033			392,945				4.73	%
						$	928,300

On March 25, 2026, the Company completed a private placement of C$550,000 of Senior Notes. The Senior Notes due 2028, 2031 and 2033 are each held by a group of institutional investors.

The Revolving Credit Facility, Senior Notes due 2028, Senior Notes due 2031 and Senior Notes due 2033 rank equally in terms of seniority and have similar financial covenants, including leverage and interest coverage. The Company was in compliance with all covenants as of March 31, 2026. The Company is limited from undertaking certain mergers, acquisitions and dispositions without prior approval.

11. AR Facility

Under the accounts receivable facility (the “AR Facility”), certain of the Company's subsidiaries continuously sell trade accounts receivable and contract assets (the “Receivables”) to wholly owned special purpose entities at fair market value. The special purpose entities in turn sell the Receivables to third-party financial institutions (the “Purchasers”). All transactions under the AR Facility are accounted for as a true sale in accordance with ASC 860, Transfers and Servicing (“ASC 860”) and accordingly sold receivables are derecognized from the consolidated balance sheet.

On March 18, 2026, the Company renewed its AR Facility with two third-party financial institutions, with a term extending to March 18, 2028 and a capacity of $250,000. As of March 31, 2026, the Company’s draw under the AR Facility was $226,535.

The Company continues to service the Receivables sold. As of March 31, 2026, the servicing liability was nil.

Under the AR Facility, the Company receives a cash payment and a deferred purchase price (“Deferred Purchase Price” or “DPP”) for sold Receivables. The DPP is paid to the Company in cash on behalf of the Purchaser as the Receivables are collected. As at March 31, 2026, the DPP was $92,491 (December 31, 2025 - $121,980) and was included in Prepaid expenses and other current assets on the Consolidated Balance Sheets. For the three months ended March 31, 2026, Receivables sold under the AR Facility were $531,203 and cash collections from customers on Receivables sold were $542,308, all of which were reinvested in new Receivables purchases and are included in cash flows from operating activities in the consolidated statement of cash flows. As of March 31, 2026, the outstanding principal on trade accounts receivable, net of expected credit losses, sold under the AR Facility was $217,970; and the outstanding principal on contract assets, current and non-current, sold under the AR Facility was $138,158. See note 17 for fair value information on the DPP.

For the three months ended March 31, 2026, the Company recognized a gain related to Receivables sold of $18 (2025 - $14) that was recorded in other income in the consolidated statement of earnings. The fair value of the Receivables sold subsequent to the initial sale approximates carrying value.

The non-cash investing activities associated with the DPP for the three months ended March 31, 2026, were $22,083.

12. Variable interest entities

The Company holds variable interests in certain Variable Interest Entities (“VIE”) in its Investment Management segment which are not consolidated as it was determined that the Company is not the primary beneficiary. The Company’s involvement with these entities is in the form of advisory fee arrangements and equity co-investments (typically 1%-2%). Equity co-investments are included in Other non-current assets on the consolidated balance sheets.

The following table provides the maximum exposure to loss related to these non-consolidated VIEs:

		March 31,				December 31,
		2026				2025
Non-consolidated investments		$	67,106			$	60,601
Co-investment commitments			22,231				23,546
Maximum exposure to loss		$	89,337			$	84,147

Page 14 of 24

13. Redeemable non-controlling interests

The minority equity positions in the Company’s subsidiaries are referred to as redeemable non-controlling interests (“RNCI”). The RNCI are considered to be redeemable securities. Accordingly, the RNCI is recorded at the greater of (i) the redemption amount or (ii) the amount initially recorded as RNCI at the date of inception of the minority equity position. This amount is recorded in the “mezzanine” section of the balance sheet, outside of shareholders’ equity. Changes in the RNCI amount are recognized immediately as they occur. The following table provides a reconciliation of the beginning and ending RNCI amounts:

		2026
Balance, January 1		$	1,285,046
RNCI share of earnings			4,295
RNCI redemption increment			30,518
Distributions paid to RNCI			(11,229	)
Purchase of interests from RNCI			(25,602	)
Sale of interests to RNCI			8,328
RNCI recognized on business acquisitions			5,137
Balance, March 31		$	1,296,493

The Company has shareholders’ agreements in place at each of its non-wholly owned subsidiaries. These agreements allow the Company to “call” the RNCI at a price determined with the use of a formula price, which is usually equal to a fixed multiple of average annual net earnings before income taxes, interest, depreciation, and amortization. The agreements also have redemption features which allow the owners of the RNCI to “put” their equity to the Company at the same price subject to certain limitations. The formula price is referred to as the redemption amount and may be paid in cash or in Subordinate Voting Shares. The redemption amount as of March 31, 2026, was $1,081,918 (December 31, 2025 - $1,068,617). The redemption amount is lower than that recorded on the balance sheet as the formula price of certain RNCI are lower than the amount initially recorded at the inception of the minority equity position. If all put or call options were settled with Subordinate Voting Shares as at March 31, 2026, approximately 9,900,000 such shares would be issued.

Increases or decreases to the formula price of the underlying shares are recognized in the statement of earnings as the NCI redemption increment.

14. Net earnings per common share

Stock options were anti-dilutive for the three months ended March 31, 2026 and the three months ended March 31, 2025.

The following table reconciles the basic and diluted common shares outstanding:

		Three months ended
		March 31
(in thousands)		2026				2025

Weighted average common shares - Basic			51,104				50,615
Exercise of stock options			-				-
Weighted average common shares - Diluted			51,104				50,615

15. Stock-based compensation

Corporate stock option plan

The Company has a stock option plan for certain officers, key full-time employees and directors of the Company and its subsidiaries. Options are granted at the market price for the underlying shares on the day immediately prior to the date of grant. Each option vests over a four-year term, expires five years from the date granted and allows for the purchase of one Subordinate Voting Share. All Subordinate Voting Shares issued are new shares. As at March 31, 2026, there were 1,838,825 options available for future grants.

Grants under the Company’s stock option plan are equity-classified awards.

Stock option activity for the three months ended March 31, 2026 was as follows:

										Weighted average
						Weighted				remaining				Aggregate
		Number of				average				contractual life				intrinsic
		options				exercise price				(years)				value
Shares issuable under options -
December 31, 2025			3,420,780			$	125.11
Granted			10,000				110.16
Shares issuable under options -
March 31, 2026			3,430,780			$	125.06				2.7			$	9,868
Options Vested - March 31, 2026			1,680,378			$	119.64				1.9			$	6,829

The amount of compensation expense recorded in the statement of earnings for the three months ended March 31, 2026 was $7,451 (2025 - $8,085). As of March 31, 2026, there was $47,043 of unrecognized compensation cost related to non-vested awards which is expected to be recognized over the next 4 years. As at March 31, 2026, the fair value of options vested was $299 (December 31, 2025 - $32,341).

Performance Stock Units (“PSUs”)

On October 1, 2024, Colliers extended the existing management service agreement with its Chairman and Chief Executive Officer, Jay S. Hennick, to January 1, 2029. In connection with this extension, a performance-based long term incentive plan was created. Under this arrangement, Mr. Hennick was granted a total of 428,174 cash-settled PSUs that are subject to the satisfaction of certain performance-based vesting conditions during the period ending January 1, 2029. To the extent incentives are earned, the Company will be obligated to make a one-time cash payment equal to the number of vested PSUs multiplied by the twenty-day volume-weighted average trading price of the Subordinate Voting Shares at such time. The performance units cannot be share settled and do not give Mr. Hennick any rights as a shareholder.

The amount of stock-based compensation expense related to the PSUs recorded in the statement of earnings for the three months ended March 31, 2026 was a recovery of $10,532 (2025 – recovery of $1,433).

As at March 31, 2026, the estimated fair value of the PSUs is $19,986 and there is approximately $4,267 of total estimated unrecognized compensation expense related to the arrangement which are expected to be expensed over the next four years. As at March 31, 2026, the performance vesting criteria related to 107,043 PSUs has been satisfied. The PSU plan is a liability classified stock-based compensation plan and as at March 31, 2026, $15,719 is reported in Other liabilities on the Company’s consolidated balance sheets.

Subsidiary stock-based compensation plans

The Company has established stock-based compensation plans with certain employees granting them awards in the Company’s Investment Management segment. Awards granted under these plans require continued service over three to five-year vesting periods. Settlement of these awards will occur in the subsidiary’s stock. Since the subsidiary’s stock is redeemable by the holder, they are treated in a manner consistent with liability-classified options, with initial measurement at the fair value on the grant date and subsequent remeasurement at the end of each reporting period. As the awards are subject to vesting conditions, the graded attribution method is applied and compensation expense is recognized over the vesting period.

Page 16 of 24

Consistent with RNCI arrangements (see note 13), the fair values of the awards are based upon a fixed multiple of average annual net earnings before income taxes, interest, depreciation and amortization of the subsidiary with adjustments for debt. The calculated value also reflects a 25% discount to incorporate forfeiture risk and limitations on the timing and extent of redemption of the subsidiary’s stock.

In relation to subsidiary stock-based compensation plans, the Company incurred stock-based compensation expense of $4,256 during the three months ended March 31, 2026 (2026 – nil). As at March 31, 2026, there was $41,082 of unrecognized compensation cost related to non-vested plans which is expected to be recognized over the next five years. As at March 31, 2026, the fair value of options vested under subsidiary stock-based compensation plans was $4,308.

16. Income tax

Income tax expense for the three months ended March 31, 2026, reflected an effective tax rate of 43.4% (2025 - 34.6%) relative to the Canadian federal statutory corporate income tax rate of 15% (2025 - 15%). The tax rates of both the current period and prior period were impacted by Canadian provincial income taxes, foreign tax effects, valuation allowances and permanent non-deductible expenses. The increase in effective tax rate compared to the prior period is primarily due to valuation allowance recorded on losses incurred by certain European entities.

The 15% Canadian federal statutory corporate income tax rate is derived from the 38% Part I federal tax rate, net of the 10% federal tax abatement and the 13% general rate reduction.

17. Financial instruments

Fair values of financial instruments

The following table provides the financial assets and liabilities carried at fair value measured on a recurring basis as of March 31, 2026:

		Level 1				Level 2				Level 3
Assets
Equity securities		$	13,426			$	3			$	-
Debt securities			21,110				21,757				-
Mortgage derivative assets			-				-				7,075
Mortgage warehouse receivables			-				203,511				-
Interest rate swap assets			-				2,203				-
Deferred Purchase Price on AR Facility			-				-				92,491
Total assets		$	34,536			$	227,474			$	99,566
Liabilities
Interest rate swap liabilities		$	-			$	396			$	-
Deferred acquisition consideration			-				41,296				-
Contingent acquisition consideration			-				-				9,672
Total liabilities		$	-			$	41,692			$	9,672

Equity securities, debt securities, mortgage derivative assets, interest rate swap assets and the deferred purchase price on the AR Facility are included in prepaid expenses and other current assets or other assets if greater than one year. Interest rate swap assets are included in other liabilities on the consolidated balance sheets. Other than the assets and liabilities acquired in relation to business combinations (see note 4), there were no significant non-recurring fair value measurements recorded during the period ended March 31, 2026.

Page 17 of 24

Debt and equity securities

The Company records debt and equity securities at fair value on the consolidated balance sheets. These financial instruments are valued based on observable market data that may include quoted market prices, dealer quotes, market spreads, cash flows, the US Treasury yield curve, trading levels, market consensus prepayment speeds, credit information and the instruments’ terms and conditions and are classified as Level 2 of the fair value hierarchy.

Investments in debt and equity securities where quoted prices are readily available are classified as Level 1 in the fair value hierarchy. The Company increases or decreases its investment each reporting period by the change in the fair value of the investment reported in net earnings on the consolidated statements of earnings.

Mortgage-related derivatives

Interest rate lock commitments and forward sale commitments are derivative instruments which use a discounted cash flow model and consider observable market data in determining their fair values, particularly changes in interest rates. In the case of interest rate lock commitments, the fair value measurement also considers the expected net cash flows associated with the servicing of the loans. The Company also considers the impact of unobservable inputs related to counterparty non-performance risk when measuring the fair value of these derivatives. Therefore, these mortgage-related derivatives are categorized as Level 3. The mortgage-related derivative assets and liabilities are included in Prepaid expenses and other current assets and Accounts payable and accrued expenses, respectively, on the consolidated balance sheets.

Given the credit quality of the Company’s counterparties, the short duration of interest rate lock commitments and forward sale commitments and the Company’s historical experience, management does not believe the risk of non-performance is significant. An increase in counterparty non-performance risk assumptions would result in a lower fair value measurement.

Changes in the fair value of the net mortgage derivative assets and liabilities comprise the following:

		2026
Balance, January 1		$	5,475
Settlements			(18,602	)
Realized gains recorded in earnings			13,127
Unrealized gains recorded in earnings			7,075
Balance, March 31		$	7,075

Mortgage warehouse receivables

As at March 31, 2026, all warehouse facility liabilities are supported by mortgage warehouse receivables which are under commitment to be purchased by a qualifying investor. These assets are classified as Level 2 in the fair value hierarchy as most of the inputs are readily observable.

AR Facility deferred purchase price (“DPP”)

The Company recorded a DPP under its AR Facility. The DPP represents the difference between the fair value of the Receivables sold and the cash purchase price and is recognized at fair value as part of the sale transaction. The DPP is remeasured each reporting period in order to account for activity during the period, including the seller’s interest in any newly transferred Receivables, collections on previously transferred Receivables attributable to the DPP and changes in estimates for credit losses. Changes in the DPP attributed to changes in estimates for credit losses are expected to be immaterial, as the underlying Receivables are short-term and of high credit quality. The DPP is valued using Level 3 inputs, primarily discounted cash flows, with the significant inputs being discount rates ranging from 5.0% to 7.0% depending upon the aging of the Receivables. See note 11 for information on the AR Facility.

Changes in the fair value of the DPP comprises the following:

		2026
Balance, January 1		$	121,980
Additions to DPP			22,083
Collections on DPP			(51,315	)

Balance, March 31		$	92,491

Financial derivatives

The Company has entered into interest rate swap agreements (“IRS”) to convert floating interest on US dollar denominated debt to fixed interest rates. The interest rate swaps are measured at fair value and are included in Other assets on the consolidated balance sheets. The table below summarizes the details of the interest rate swaps in place as at March 31, 2026.

	Effective	Maturity		Notional Amount			Interest rates
	Date	Date		of US dollar debt			Floating		Fixed
2022 IRS A	July 15, 2022	May 27, 2027		$	150,000		SOFR		2.8020%
2022 IRS B	December 21, 2022	May 27, 2027		$	250,000		SOFR		3.5920%
2023 IRS A	April 28, 2023	May 27, 2027		$	100,000		SOFR		3.7250%
2023 IRS B	December 5, 2023	May 27, 2027		$	100,000		SOFR		4.0000%
2025 IRS A	May 27, 2027	November 29, 2029		$	200,000		SOFR		3.4340%
2025 IRS B	May 27, 2027	November 29, 2029		$	200,000		SOFR		3.4460%
2025 IRS C	May 27, 2027	November 29, 2029		$	200,000		SOFR		3.4800%

All interest rate swaps list in the table above (collectively the “Designated IRSs”) are being accounted for as cash flow hedges and are measured at fair value on the consolidated balance sheets. Gains or losses on the Designated IRSs, which are determined to be effective as hedges, are reported in accumulated other comprehensive income (“AOCI”). As at March 31, 2026, unrealized gain of $1,807 (December 31, 2025 - loss of $2,538) on the Designated IRSs were included in AOCI.

Deferred acquisition consideration

The fair value of deferred acquisition consideration is determined based upon inputs that are readily observable, primarily interest rates, and are classified as Level 2 in the fair value hierarchy.

Contingent acquisition consideration

The inputs to the measurement of the fair value of contingent consideration related to acquisitions are Level 3 inputs. The fair value measurements were made using a discounted cash flow model; significant model inputs were expected future operating cash flows (determined with reference to each specific acquired business) and discount rates (which range from 3.5% to 10.1%, with a weighted average of 9.6%). The wide range of discount rates is attributable to the level of risk related to economic growth factors combined with the length of the deferred payment periods; and the dispersion was driven by unique characteristics of the businesses acquired and the respective terms for these contingent payments. A 5% increase in the weighted average discount rate would reduce the fair value by $1,200. See note 4 for discussion on contingent acquisition consideration.

Page 19 of 24

Changes in the fair value of the contingent acquisition consideration liability comprises the following:

		2026
Balance, January 1		$	8,533
Fair value adjustments (note 7)			1,139
Balance, March 31		$	9,672
Non-current portion		$	9,672

The carrying amounts for cash, restricted cash, accounts receivable, accounts payable, advisor loans, other receivables and accrued liabilities approximate their estimated fair values due to the short-term nature of these instruments, unless otherwise indicated. The carrying value of the Company’s Revolving Credit Facility and other short-term borrowings approximate their estimated fair value due to their short-term nature and variable interest rate terms.

The carrying amount and the estimated fair value of Senior Notes is presented in the table below. Interest rate yield curves, interest rate indices and market prices (Level 2 inputs within the fair value hierarchy) are used in determining the fair value of the Senior Notes.

		March 31, 2026								December 31, 2025
		Carrying				Fair				Carrying				Fair
		amount				value				amount				value
Senior Notes		$	928,300			$	875,754			$	542,044			$	500,019

18. Commitments and Contingencies

Acquisition

On February 3, 2026, the Company announced it has entered into a definitive agreement to acquire Ayesa Engineering S.A.U. (“Ayesa Engineering”). Ayesa Engineering is a multidiscipline engineering and project management firm headquartered in Seville, Spain that provides technical consulting services across four continents. The transaction is expected to close in the second quarter of 2026 for total cash consideration of approximately $700,000.

Claims and Litigation

In the normal course of operations, the Company is subject to routine claims and litigation incidental to its business. Litigation currently pending or threatened against the Company includes disputes with former employees and commercial liability claims related to services provided by the Company. The Company believes resolution of such proceedings, combined with amounts accrued, will not have a material impact on the Company’s financial condition or the results of operations.

Contingencies associated with US government sponsored enterprises

Colliers Debt & Structured Finance is a lender in the Fannie Mae DUS Program. Commitments for the origination and subsequent sale and delivery of loans to Fannie Mae represent those mortgage loan transactions where the borrower has locked an interest rate and scheduled closing and the Company has entered into a mandatory delivery commitment to sell the loan to Fannie Mae. As discussed in note 17, the Company accounts for these commitments as derivatives recorded at fair value.

Colliers Debt & Structured Finance is obligated to share in losses, if any, related to mortgages originated under the DUS Program. These obligations expose the Company to credit risk on mortgage loans for which the Company is providing underwriting, servicing, or other services under the DUS Program. Net losses on defaulted loans are shared with Fannie Mae based upon established loss-sharing ratios, and typically, the Company is subject to sharing up to one-third of incurred losses on loans originated under the DUS Program. As of March 31, 2026, the Company has funded and sold loans subject to such loss sharing obligations with an aggregate unpaid principal balance of approximately $7,718,782. (December 31, 2025 - $7,196,000) As at March 31, 2026, the loss reserve was $13,646 (December 31, 2025 - $12,655) and was included within Other liabilities on the consolidated balance sheets.

Page 20 of 24

Pursuant to its licenses with Fannie Mae, Ginnie Mae and the Department of Housing and Urban Development, Colliers Debt & Structured Finance is required to maintain certain standards for capital adequacy which include minimum net worth and liquidity requirements. If it is determined at any time that Colliers Debt & Structured Finance fails to maintain appropriate capital adequacy, the licensor reserves the right to terminate their servicing authority for all or some of the portfolio. As at March 31, 2026, Colliers Debt & Structured Finance was in compliance with all such requirements.

19. Revenue

Disaggregated revenue

Colliers has disaggregated its revenue from contract with customers by type of service and reportable segment as presented in the following table. See Note 2 for additional information on a change to the Company’s reportable segments. The three months ended March 31, 2025 have been recast for comparability.

		Three months

		2026				2025
Commercial Real Estate
Leasing		$	250,980			$	227,007
Capital Markets			219,315				149,152

Total			135,266				126,202
Corporate			188				122
Total Revenue		$	1,313,472			$	1,141,170

Revenue associated with the Company’s debt finance and loan servicing operations are outside the scope of ASC 606, Revenue from Contracts with Customers (“ASC 606”). For the three months ended March 31, 2026, $22,342 of Capital Markets revenue (2025 - $8,815) and $12,435 of Other Revenue (2025 - $11,474) respectively, was excluded from the scope of ASC 606. Substantially all of these revenues were included within the Commercial Real Estate segment.

Contract balances

As at March 31, 2026, the Company had contract assets totaling $196,825 of which $173,320 was current ($178,276 as at December 31, 2025 - of which $161,016 was current). During 2026, approximately 64% of the current contract assets were moved to accounts receivable or sold under the AR Facility (Note 11).

As at March 31, 2026, the Company had contract liabilities (all current) totaling $80,950 ($80,350 as at December 31, 2025). $50,589 of the contract liability balance at the beginning of the year was recognized to revenue in 2026, respectively (2025 - $42,301).

Page 21 of 24

Certain constrained revenues may arise from services that began in a prior reporting period. Consequently, a portion of the revenue the Company recognizes in the current period may be partially related to the services performed in prior periods. Typically, less than 5% of Leasing and Capital Markets revenue recognized in a prior period had previously been constrained and substantially all investment management incentive fees recognized in the year were previously constrained.

20. Segmented information

REPORTABLE SEGMENTS

Colliers has identified three reportable operating segments: Commercial Real Estate, Engineering and Investment Management. Corporate represents unallocated costs of global administrative functions and the corporate head office. The groupings are based on the manner in which the segments are managed. See Note 2 for additional information on a change to the Company’s reportable segments.

The Chief Operating Decision Maker (“CODM”) of the Company uses Adjusted EBITDA to compare each segments current performance against prior periods and previous forecasts which is used to guide strategy and make decisions about the allocation of resources. The Chief Executive Officer is determined to be the Company’s CODM.

Segment 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, optimization and integration costs and (ix) stock-based compensation expense.

Indirect operating costs includes the selling, general and administration expenses of the Company excluding stock-based compensation and restructuring, optimization and integration costs. It also includes an adjustment to remove the impact of gains attributable to MSRs.

The CODM is not provided with total asset information by segment and does not consider total assets in determining the performance of the segments nor in determining resource allocation. Therefore, total assets by segment is not disclosed.

The three months ended March 31, 2025 have been recast for comparability.

COLLIERS INTERNATIONAL GROUP INC.

Management’s discussion and analysis

For the three months ended March 31, 2026

(in US dollars)

May 8, 2026

The following management’s discussion and analysis (“MD&A”) should be read together with the unaudited interim consolidated financial statements and the accompanying notes of Colliers International Group Inc. (“we,” “us,” “our,” the “Company” or “Colliers”) for the three months ended March 31, 2026, and the Company’s audited consolidated financial statements and MD&A for the year ended December 31, 2025. The consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). All financial information herein is presented in United States dollars.

The Company has prepared this MD&A with reference to National Instrument 51-102 – Continuous Disclosure Obligations of the Canadian Securities Administrators (the “CSA”). Under the U.S./Canada Multijurisdictional Disclosure System, the Company is permitted to prepare this MD&A in accordance with the disclosure requirements of Canada, which requirements are different from those of the United States. This MD&A provides information for the three months ended March 31, 2026 and up to and including May 8, 2026.

Additional information about the Company can be found on SEDAR+ at www.sedarplus.ca and on EDGAR at www.sec.gov.

This MD&A includes references to “internal revenue growth rate”, “adjusted EBITDA”, “local currency revenue and adjusted EBITDA growth rate”, “adjusted EPS”, “free cash flow,” “assets under management (“AUM”)” and fee paying AUM (“FPAUM”), which are financial measures that are not calculated in accordance with GAAP. For a reconciliation of these non-GAAP measures to the most directly comparable GAAP financial measures, see “Reconciliation of non-GAAP financial measures”.

Consolidated review

Our consolidated revenues for the three months ended March 31, 2026 were $1.31 billion, an increase of 15% versus the prior year quarter (12% in local currency) with solid growth across all segments. The GAAP diluted net loss per share was $0.47 compared to a loss of $0.08 in the prior year quarter. The greater net loss per share was primarily due to (i) higher non-controlling interest redemption increment, (ii) higher acquisition-related expenses, and (iii) higher income taxes in the period. Adjusted earnings per share (see “Reconciliation of non-GAAP financial measures” below) were $0.91 relative to $0.87 in the prior year. The increase was primarily attributable to higher revenues from a combination of internal growth and acquisitions. GAAP diluted net earnings per share and adjusted earnings per share for the three months ending March 31, 2026 were not significantly impacted by changes in foreign exchange rates.

In February 2026, the Company entered into an agreement to acquire Ayesa Engineering S.A.U. (Ayesa Engineering), a 3,200-person multidiscipline engineering firm, headquartered in Seville, Spain. The acquisition is expected to close in late May 2026, subject to customary closing conditions, with a purchase price of approximately $700 million. Ayesa Engineering generated approximately $370 million in revenues in 2025.

In March 2026, the Company named Christian Mayer to an expanded role as Global Chief Financial Officer & CEO of Commercial Real Estate, and Elias Mulamoottil to an expanded role as Global Chief Investment Officer & CEO of Engineering (see “Segment Reporting Change” below).

In March 2026, the Company completed a private placement of approximately $400 million of 4.73% fixed rate senior unsecured notes due 2033, and negotiated an extension of its revolving credit facility (“Revolving Credit Facility”).

Page 3 of 13

Segment Reporting Change

The Company has realigned its Commercial Real Estate and Engineering segments to reflect the new management reporting lines effective in the first quarter of 2026. Accordingly, the legacy local project management operations, which primarily serve leasing and occupier clients, are now reported in the Commercial Real Estate segment for all periods presented. The Chief Operating Decision Maker (“CODM”) reviews financial information and evaluates the overall business on this revised basis.

The operating segment change impacts the presentation in note 19 and note 20 of our consolidated financial statements without any impact on the consolidated balance sheet, consolidated statement of earnings or the consolidated statement of cash flows. Prior year segment comparatives have been recast to improve comparability. The Investment Management segment remains unchanged.

Results of operations – three months ended March 31, 2026

For the three months ended March 31, 2026, revenues were $1.31 billion, up 15% relative to the prior year quarter (12% in local currency) led by internal growth of 7% from an uptick in Commercial Real Estate transactional activity as well as business acquisitions which contributed the remainder of the growth.

The GAAP operating earnings for the first quarter were $35.0 million versus $31.6 million in the prior year quarter. The operating earnings margin was 2.7% as compared to 2.8% in the prior year quarter. The decline in margin was attributable to (i) higher acquisition-related expenses and (ii) higher intangible asset amortization expense related to recent acquisitions, partly offset by higher revenues from both internal growth and acquisitions. Adjusted EBITDA (see “Reconciliation of non-GAAP financial measures” below) of $124.8 million was up 8% versus $116.0 million in the prior year quarter, on higher revenues, higher equity earnings from non-consolidated entities, and the favourable impact of acquisitions. The Adjusted EBITDA margin was 9.5% in the quarter, down compared to 10.2% in the prior year quarter and was impacted by continued investments in Investment Management.

Depreciation expense was $20.3 million relative to $18.6 million in the prior year quarter with the increase attributable to technology investments and the impact of recent business acquisitions.

Amortization expense was $47.7 million, versus $44.8 million recorded in the prior year quarter, primarily driven by intangible assets added through recent acquisitions.

Net interest expense was $22.9 million, versus $22.6 million recorded in the prior year quarter. The increase in the interest expense was attributable to a higher average balance in our Revolving Credit Facility which was partially offset by lower floating reference rates. The average interest rate on debt during the period was 4.2%, relative to 4.6% in the prior year quarter.

Consolidated income tax expense for the quarter was $8.3 million, relative to $4.7 million in the prior year quarter. The current quarter’s effective tax rate was 43.4% versus 34.6% in the prior year quarter. The higher rate was due to higher-than-expected tax rates in certain jurisdictions due to inability to recognize deferred tax benefits.

Net earnings for the quarter were $10.8 million versus $8.9 million in the prior year quarter.

Commercial Real Estate revenues totalled $841.2 million, up 14% (up 11% in local currency) versus the prior year quarter. Capital Markets revenues were up 47% with strong growth across all geographies, led by the US and EMEA. Leasing generated solid growth, up 11% largely driven by the US in industrial and office asset classes. Outsourcing revenues (including property management, valuation, mortgage servicing, advisory and local project management) were up modestly. Adjusted EBITDA was $46.2 million, up 18% (20% in local currency) with operating leverage from higher transactional revenues largely offset by continued strategic investments in recruiting across the segment.

Engineering revenues totalled $336.8 million, up 23% (18% in local currency) compared to the prior year quarter driven by the favourable impact of recent acquisitions and internal growth. Adjusted EBITDA was $26.9 million, up 12% (9% in local currency) over the prior year quarter, with margins down slightly on lower utilization in certain end-markets.

Page 4 of 13

Investment Management revenues were $135.3 million, up 7% (6% in local currency) relative to the prior year quarter. Excluding pass-through performance fees, revenues were $129.3 million, up 8% (8% in local currency) driven by the favourable impact of a recent acquisition. Adjusted EBITDA was $50.6 million, down 8% (down 9% in local currency) compared to the prior year quarter, reflecting planned investments in global fundraising and ongoing streamlining and integration initiatives to unify the business under the Harrison Street Asset Management brand. AUM was $109.3 billion as of March 31, 2026, up 9% from March 31, 2025. FPAUM was $53.5 billion as of March 31, 2026, up 7% from March 31, 2025.

Unallocated global corporate Adjusted EBITDA was $1.2 million relative to a cost of $2.2 million in the prior year quarter.

Summary of quarterly results

The following table sets forth our quarterly consolidated results of operations data. The information in the table below has been derived from unaudited interim consolidated financial statements that, in management’s opinion, have been prepared on a consistent basis and include all adjustments necessary for a fair presentation of information. The information below is not necessarily indicative of results for any future quarter.

Seasonality and quarterly fluctuations

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 timing of closings on Capital Markets transactions. Revenues and earnings during the balance of the year are relatively even. Capital Markets operations comprised 16% of consolidated annual revenues for 2025. Variations can be caused by business acquisitions which alter the consolidated service mix.

2026 Outlook

The Company’s outlook for 2026 remains unchanged and includes the impact of the acquisition of Ayesa Engineering, which is expected to close in late May. On a consolidated basis, the Company expects to generate mid-teens percentage growth in each of revenues, Adjusted EBITDA and Adjusted EPS for the full year.

The financial outlook is based on the Company’s best available information as of the date of this MD&A, and remains subject to change based on numerous macroeconomic, geopolitical, international trade, health, social and related factors. The outlook includes the anticipated impact of the closing of Ayesa Engineering in the second quarter, subject to customary closing conditions being met. The outlook does not include any further acquisitions.

Liquidity and capital resources

Net cash used in operating activities for the three months ended March 31, 2026 was $187.4 million, versus usage of $84.5 million in the prior year, with the increase in usage primarily attributable to greater seasonal outflows of working capital in the first quarter. We believe that cash from operations and other existing resources, including our $2.25 billion multi-currency Revolving Credit Facility, will continue to be adequate to satisfy the ongoing working capital needs of the Company.

For the three months ended March 31, 2026, capital expenditures were $18.3 million (March 31, 2025 - $14.7 million). Capital expenditures for the year ending December 31, 2026 are expected to be between $90-$100 million and expected to be funded by (i) cash on hand and (ii) landlord inducements, in the case of certain office leases.

Net indebtedness is considered a supplementary financial measure and as of March 31, 2026 was $1.67 billion ($1.43 billion as of December 31, 2025). Net indebtedness is calculated as the current and non-current portion of long-term debt (excluding warehouse credit facilities, in accordance with our debt agreements) less cash and cash equivalents. As of March 31, 2026, the Company’s financial leverage ratio expressed in terms of net debt to pro forma Adjusted EBITDA, as defined in our debt agreements, was 2.3x (2.0x as of December 31, 2025), relative to a maximum of 3.5x permitted under our debt agreements. We were in compliance with the covenants contained in our debt agreements as of March 31, 2026 and, based on our outlook for 2026, we expect to remain in compliance with these covenants. On February 20, 2026, the Company amended its Revolving Credit Facility to a new five-year term, maturing on February 20, 2031. The amendment provides for a temporary step-up to the financial leverage ratio from 3.5x to 4.0x for up to four consecutive quarters following the completion of an acquisition where the purchase price exceeds $200 million. After the four quarters, the maximum allowable leverage ratio returns to 3.5x.

The Company’s Revolving Credit Facility is sustainability-linked and includes pricing adjustments tied to achievements of performance targets over time aligned with Colliers’ Built to Last framework available on corporate.colliers.com. For 2025, the target was to reduce greenhouse gas emissions consistent with the Science-Based Targets initiative. The Company expects to meet its target for 2025 and, if successful, will achieve a five-basis point reduction in the borrowing cost on the Revolving Credit Facility. As of March 31, 2026, the Company had $1.30 billion of unused credit under the Revolving Credit Facility.

On March 25, 2026, the Company completed a private placement of C$550 million of 4.73% fixed rate senior unsecured notes due 2033. The payment obligations under the notes rank equally with all other unsecured and unsubordinated indebtedness and have similar financial covenants with respect to leverage and interest coverage. The Company used the proceeds to repay outstanding C$ denominated borrowings under its Revolving Credit Facility and for general corporate purposes.

Colliers Mortgage utilizes warehouse credit facilities for the purpose of funding warehouse receivables. Warehouse receivables represent mortgage loans receivable, the majority of which are offset by borrowings under warehouse credit facilities which fund loans that financial institutions have committed to purchase. The warehouse credit facilities are excluded from the financial leverage calculations under our debt agreements.

On March 18, 2026, the Company renewed its accounts receivable facility (“AR Facility”) with two third-party financial institutions, with a term extending to March 18, 2028 and a capacity of $250 million (previously $200 million). The AR Facility is recorded as a sale of accounts receivable, and accordingly sold receivables are derecognized from the consolidated balance sheet. The AR Facility results in a decrease in our borrowing costs. As of March 31, 2026, the Company’s draw under the AR Facility was $226.5 million.

During the first quarter of 2026, the Company did not acquire or divest any assets in relation to seeding new Investment Management funds. The Company recorded existing assets and liabilities in relation to seeding new funds on the consolidated balance sheet (see note 6 in our consolidated financial statements). We expect to enter into such transactions from time to time to facilitate the formation of new funds.

The Company pays semi-annual dividends in cash after the end of the second and fourth quarters to shareholders of record on the last business day of the quarter. The Company’s policy is to pay dividends on its common shares in the future, subject to the discretion of our Board of Directors. On December 2, 2025, the Company’s Board of Directors declared a semi-annual dividend of $0.15 per share to shareholders of record on December 31, 2025, paid on January 14, 2026. Total common share dividends paid by the Company during the three months ended March 31, 2026 were $7.7 million (March 31, 2025 - $7.6 million).

During the three months ended March 31, 2026, the Company invested cash in acquisitions as follows: $45.0 million in acquisition of new businesses, $24.3 million in purchases of redeemable non-controlling interest and $3.0 million in contingent consideration payments. All acquisitions during the period were funded from borrowings on the Revolving Credit Facility and cash on hand (see note 4 in our consolidated financial statements). The Company expects to fund future acquisitions, including Ayesa Engineering, with borrowings on the Revolving Credit Facility and cash on hand.

Unless it contains an element of compensation, contingent consideration in relation to acquisitions is recorded at fair value each reporting period. The fair value recorded on the consolidated balance sheet as at March 31, 2026 was $9.7 million (December 31, 2025 - $8.5 million). Contingent consideration with a compensatory element is revalued at each reporting period and recognized on a straight-line basis over the term of the contingent consideration arrangement. The liability recorded on the consolidated balance sheet for the compensatory element of contingent consideration arrangements as at March 31, 2026 was $33.8 million (December 31, 2025 - $33.3 million). The contingent consideration is based on achieving specified earnings levels and is paid or payable after the end of the relevant contingency periods. As at March 31, 2026, the Company expects to make earnout payments in the range of $79.5 million to a contractual maximum of $351.8 million (December 31, 2025 - $346.8 million) through August 2030.

The following table summarizes our contractual obligations as at March 31, 2026:

(1) Figures do not include interest payments for borrowings under the Revolving Credit Facility. Assuming the Revolving Credit Facility is held until maturity, using current interest rate, we estimate that we will make $241,200 of interest payments, $49,000 of which will be made in the next 12 months.

(2) On February 3, 2026, the Company announced it has entered into a definitive agreement to acquire Ayesa Engineering S.A.U. for total cash consideration of approximately $700,000. The acquisition is expected to close in late May.

(3) Estimated fair value as at March 31, 2026.

As at March 31, 2026, we had commercial commitments totaling $28.6 million comprised of letters of credit outstanding.

Redeemable non-controlling interests

In most operations where managers or employees are also non-controlling owners, the Company is party to shareholders’ agreements. These agreements allow us to “call” the redeemable non-controlling interests (“RNCI”) at a value determined with the use of a formula price, which is in most cases equal to a multiple of trailing two-year average earnings, less debt. Non-controlling owners may also “put” their interest to the Company at the same price, with certain limitations including (i) the inability to “put” more than 25% to 50% of their holdings in any twelve-month period and (ii) the inability to “put” any holdings for at least one year after the date of our initial acquisition of the business or the date the non-controlling shareholder acquired their interest, as the case may be.

The total value of the RNCI (the “redemption amount”), as calculated in accordance with shareholders’ agreements, was $1.08 billion as of March 31, 2026 (December 31, 2025 - $1.07 billion). The amount recorded on our balance sheet under the caption “redeemable non-controlling interests” is the greater of (i) the redemption amount (as above) or (ii) the amount initially recorded as RNCI at the date of inception of the minority equity position. As at March 31, 2026, the RNCI recorded on the balance sheet was $1.30 billion (December 31, 2025 - $1.29 billion). The purchase prices of the RNCI may be paid in cash or in Subordinate Voting Shares of Colliers.

Critical accounting estimates

Critical accounting estimates are those that we deem to be most important to the portrayal of our financial condition and results of operations, and that require management’s most difficult, subjective or complex judgments due to the need to make estimates about the effects of matters that are inherently uncertain. We have identified six critical accounting estimates, which are discussed below.

1. Revenue recognition. We earn revenues from Leasing and Capital Markets brokerage transaction commissions, advisory fees, debt finance fees, property management fees, project management fees, engineering and design fees, loan servicing fees and investment management fees (including carried interest). Some of the contractual terms related to the process of earning revenue from these sources, including potentially contingent events, can be complex and may require us to make judgments about the timing of when we should recognize revenue and whether revenue should be reported on a gross basis or net basis. Changes in judgments could result in a change in the period in which revenues are reported, or in the amounts of revenue and cost of revenue reported.

2. Goodwill. Goodwill impairment testing involves assessing whether events have occurred that would indicate potential impairment and making estimates concerning the fair values of reporting units and then comparing the fair value to the carrying amount of each unit. The determination of what constitutes a reporting unit requires significant management judgment. We have three reporting units, consistent with our three operating segments. Goodwill is attributed to the reporting units at the time of acquisition. Estimates of fair value can be impacted by changes in the business environment, prolonged economic downturns or declines in the market value of the Company’s own shares and therefore require significant management judgment in their determination. When events have occurred that would suggest a potential decrease in fair value, the determination of fair value is calculated with reference to a discounted cash flow model which requires management to make certain estimates. The most sensitive estimates are estimated future cash flows and the discount rate applied to future cash flows. Changes in these assumptions could result in a materially different fair value (see note 2 in our consolidated financial statements).

3. Business combinations. The determination of fair values of assets acquired and liabilities assumed in business combinations requires the use of estimates and management judgment, particularly in determining fair values of intangible assets acquired. For example, if different assumptions were used regarding the profitability and expected attrition rates of acquired customer relationships or forecasted committed capital and assets under management related to asset management contracts, different amounts of intangible assets and related amortization could be reported.

Page 8 of 13

4. Contingent acquisition consideration. Contingent consideration is required to be measured at fair value at the acquisition date and at each balance sheet date until the contingency expires or is settled. The fair value at the acquisition date is a component of the purchase price; subsequent changes in fair value are reflected in earnings. Most acquisitions made by us have a contingent consideration feature, which is usually based on the acquired entity’s profitability (measured in terms of Adjusted EBITDA) during a one to five year period after the acquisition date. Significant estimates are required to measure the fair value of contingent consideration, including forecasting profits for the contingency period and the selection of an appropriate discount rate.

5. Mortgage servicing rights (“MSRs”). MSRs, or the rights to service mortgage loans for others, result from the sale or securitization of loans originated by the Company and are recognized as intangible assets on the consolidated balance sheet. The Company initially recognizes MSRs based on the fair value of these rights on the date the loans are sold. Subsequent to initial recognition, MSRs are amortized and carried at the lower of amortized cost or fair value. They are amortized in proportion to and over the estimated period that net servicing income is expected to be received based on projections and timing of estimated future net cash flows.

6. Allowance for credit loss reserves. Colliers Mortgage is obligated to share in losses, if any, related to mortgages originated under the Fannie Mae Delegated Underwriting and Servicing (“DUS”) Program. These obligations expose the Company to credit risk on mortgage loans for which the Company is providing underwriting, servicing, or other services under the DUS Program. Net losses on defaulted loans are shared with Fannie Mae based upon established loss-sharing ratios, and typically, the Company is subject to sharing up to one-third of incurred losses on loans originated under the DUS Program. As of March 31, 2026, the Company has funded and sold loans subject to such loss sharing obligations with an aggregate unpaid principal balance of approximately $7.7 billion. As at March 31, 2026, the loss reserve was $13.6 million (December 31, 2025 - $12.7 million) and was included within Other liabilities on the consolidated balance sheet.

Reconciliation of non-GAAP financial measures

In this MD&A, 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, optimization and integration 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.

Stock-based compensation expense			1,175				6,652
Adjusted EBITDA		$	124,803			$	116,044

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, optimization and integration 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.

Percentage revenue and Adjusted EBITDA variances presented on a local currency basis are calculated by translating the current period results of our non-US dollar denominated operations to US dollars using the foreign currency exchange rates from the periods against which the current period results are being compared. Internal growth, presented as percentage revenue variance, is calculated assuming no impact from acquired entities in the current and prior periods. Revenue from acquired entities, including any foreign exchange impacts, are treated as acquisition growth until the respective anniversaries of the acquisitions. We believe that these revenue growth rate methodologies provide a framework for assessing the Company’s performance and operations excluding the effects of foreign currency exchange rate fluctuations and acquisitions. Since these revenue growth rate measures are not calculated under GAAP, they may not be comparable to similar measures used by other issuers.

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.

Recently adopted accounting guidance

Financial Instruments-Credit Losses for Accounts Receivable and Contract Assets

In July 2025, FASB issued ASU 2025-05, Financial Instruments: Credit Losses (Topic 326) which provides a practical expedient that permits entities to assume that current economic conditions will persist over the remaining life of current accounts receivable and contract assets when developing forecasts used to estimate expected credit losses. The amendments are effective for fiscal years and interim periods beginning after December 15, 2025. The Company adopted the ASU prospectively in the current annual financial statements. The adoption did not have a material impact on the Company's consolidated financial statements and related disclosures.

Recently issued accounting guidance, not yet adopted

Reporting Comprehensive Income – Expense Disaggregation Disclosures

In November 2024, FASB issued ASU No. 2024-03 Expense Disaggregation Disclosures which requires disaggregated disclosure of income statement expenses. The ASU does not require changes to the expense captions an entity presents on the face of the income statement, rather, it requires disaggregation of certain expense captions within the footnotes to the financial statements. This ASU is effective for annual periods beginning after December 15, 2026 with early adoption permitted. The Company is currently assessing the impacts of this ASU on its disclosures.

Improvements to the Accounting for Internal-Use Software

In September 2025, FASB issued ASU No. 2025-06 Targeted Improvements to the Accounting for Internal-Use Software. The amendments in this update accommodates changes to software development approaches by removing reference to development stages and requiring the capitalization of software costs when both i) management has authorized and committed funding a software project, and ii) when it is probable that the project will be completed and used to perform the function intended. The improvements will provide for greater consistency in capitalization of development costs as they relate to internal-use software. The amendments are effective for annual periods beginning after December 15, 2027, with early adoption permitted at the beginning of an annual reporting period. The Company is currently assessing the impacts of this ASU on its financial statements.

Financial instruments

We use financial instruments as part of our strategy to manage the risk associated with interest rates and currency exchange rates. We do not use financial instruments for trading or speculative purposes.

In 2022 and 2023, the Company entered into interest rate swap agreements (the “existing swaps”) to convert SOFR floating interest rates to fixed rates to hedge $600 million US dollar borrowings under the Revolving Credit Facility at fixed interest rates ranging from 2.802% and 4.000% with a maturity date of May 2027. In 2025, the Company entered into swap agreements (the “new swaps”) to hedge an additional $600 million of US dollar borrowings under the Revolving Credit Facility, effective May 2027 with fixed interest rates ranging from 3.434% to 3.480% and a maturity date of November 2029. Both the existing and new swaps are measured at fair value on the consolidated balance sheet. Gains or losses on the existing and new swaps which are determined to be effective as hedges, are reported in other comprehensive income.

Financial instruments involve risks, such as the risk that counterparties may fail to honor their obligations under these arrangements. If we have financial instruments outstanding and such events occur, our results of operations and financial position may be adversely affected.

Transactions with related parties

As at March 31, 2026, the Company had $18.7 million of loans receivable from shareholders of subsidiaries (December 31, 2025 - $18.8 million). The majority of the loans receivable represent amounts to finance the sale of non-controlling interests in subsidiaries to senior managers. The loans are of varying principal amounts and interest rates which range from nil to 6.0%. These loans are due on demand or mature on various dates up to 2030 but are open for repayment without penalty at any time.

Outstanding share data

The authorized capital of the Company consists of an unlimited number of preference shares, issuable in series, an unlimited number of Subordinate Voting Shares and an unlimited number of Multiple Voting Shares. The holders of Subordinate Voting Shares are entitled to one vote in respect of each Subordinate Voting Share held at all meetings of the shareholders of the Company. The holders of Multiple Voting Shares are entitled to twenty votes in respect of each Multiple Voting Share held at all meetings of the shareholders of the Company. Each Multiple Voting Share is convertible into one Subordinate Voting Share at any time at the election of the holders thereof.

As of the date hereof, the Company has outstanding 49,778,127 Subordinate Voting Shares and 1,325,694 Multiple Voting Shares. In addition, as at the date hereof 3,430,780 Subordinate Voting Shares are issuable upon exercise of options granted under the Company’s stock option plan. On May 7, 2025, the Company announced a normal course issuer bid (“NCIB”) effective from May 9, 2025 to May 8, 2026. The Company is entitled to repurchase up to 4,300,000 Subordinate Voting Shares on the open market pursuant to the NCIB.

Canadian tax treatment of common share dividends

For the purposes of the enhanced dividend tax credit rules contained in the Income Tax Act (Canada) and any corresponding provincial and territorial tax legislation, all dividends (and deemed dividends) paid by us to Canadian residents on our Subordinate Voting Shares and Multiple Voting Shares are designated as “eligible dividends”. Unless stated otherwise, all dividends (and deemed dividends) paid by us hereafter are designated as “eligible dividends” for the purposes of such rules.

Disclosure controls and procedures

Disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed in reports filed or submitted by us under U.S. and Canadian securities legislation is recorded, processed, summarized and reported within the time periods specified in those rules, and include controls and procedures designed to ensure that information required to be disclosed in reports filed or submitted by us under U.S. and Canadian securities legislation is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to permit timely decisions regarding required disclosure. The Chief Executive Officer and Chief Financial Officer have evaluated the effectiveness of the design and operation of our disclosure controls and procedures, as defined in the rules of the U.S. Securities and Exchange Commission and the Canadian Securities Administrators, as at March 31, 2026. Based on this evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as at March 31, 2026.

Changes in internal control over financial reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Any system of internal control over financial reporting, no matter how well-designed, has inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Management has used the Committee of Sponsoring Organizations of the Treadway Commission (COSO) 2013 framework to evaluate the effectiveness of our internal control over financial reporting.

During the three months ended March 31, 2026, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Legal proceedings

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 2026, 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.
