Notes to Consolidated Financial Statements

(unaudited)

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

Colliers International Group Inc. (“Colliers” or the “Company”) provides commercial real estate professional services and investment management to corporate and institutional clients in 35 countries around the world (70 countries including affiliates and franchisees). Operationally, Colliers is organized into three distinct segments: Real Estate Services, Engineering and Investment Management (“IM”).

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, 2024.

These Financial Statements follow the same accounting policies as the most recent audited consolidated financial statements, except as noted in Note 3. 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 June 30, 2025 and the results of operations and its cash flows for the three and six months ended June 30, 2025 and 2024. All such adjustments are of a normal recurring nature. The results of operations for the six months ended June 30, 2025, are not necessarily indicative of the results to be expected for the year ending December 31, 2025.

Recently issued accounting guidance, not yet adopted

Improvements to Income Tax Disclosures

In December 2023, FASB issued ASU No. 2023-09 Improvements to Income Tax Disclosures. The amendments in this update encourage transparency in income tax disclosures by requiring consistent categories and greater disaggregation of information in the rate reconciliation and income taxes paid disclosures. The amendments are effective for annual periods beginning after December 15, 2024 with early adoption permitted. The Company is currently assessing the impacts of this ASU on its annual tax disclosures.

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.

4.	Acquisitions

During the six months ended June 30, 2025, the Company acquired controlling interests in five businesses, one in Real Estate Services and four in Engineering.

Real Estate Services

In June 2025, the Company acquired a controlling interest in Triovest Inc., a provider of asset management, property management and advisory services in Canada.

Engineering

In March 2025, the Company acquired a controlling interest in Ethos Urban Pty Ltd., an engineering firm in Australia.

In May 2025, the Company acquired three engineering and design firms. Terra Consulting in the United States and Higher Ground Consulting and Herold Engineering in Canada.

The acquisition date fair values of consideration transferred consisted of $59,703 in cash (net of cash acquired of $5,726). The Company acquired $1,204 of net assets, excluding cash and recognized goodwill of $34,749 and intangible assets of $28,548. The Company also recognized redeemable non-controlling interest of $4,797 on the consolidated balance sheets.

As of June 30, 2025, the Company has not completed its analysis to assign fair values to all identifiable tangible and intangible assets acquired in 2025 and, 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.

During the period ended June 30, 2025, the Company made no significant adjustments to the provisional fair values allocated to acquired assets and liabilities for acquisitions completed in 2024.

The purchase price allocation of acquisitions result in the recognition of goodwill. The primary factors contributing to goodwill acquired in the six months ended June 30, 2025 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 six months ended June 30, 2025, goodwill in the amount of $2,126 is deductible for income tax purposes.

2024 acquisitions

During the six months ended June 30, 2024, the Company acquired a controlling interest in one business in the Americas, Lanard & Axilbund, LLC (operating as Colliers Philadelphia), a commercial real estate services firm in the United States. The acquisition date fair value of consideration transferred consisted of $17,772 in cash (net of cash acquired of $1,397).

Contingent acquisition consideration

The Company typically structures its business acquisitions to include contingent consideration. 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 June 30, 2025, was $11,977 (December 31, 2024 - $36,695). See note 16 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 June 30, 2025, was $47,327 (December 31, 2024 - $44,280). 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 $110,672 to $241,081, relative to a maximum contractual amount of $321,024. These contingencies will expire during the period extending to March 2029.

During the six months ended June 30, 2025, the Company acquired real estate assets in the US in relation to seeding new funds. In addition, the Company divested two real estate asset portfolios in Europe which were held at December 31, 2024. There was no significant impact on net earnings related to warehouse fund assets in the three and six months ended June 30, 2025, or 2024.

The following table summarizes the warehouse fund assets:

7.	Intangible assets

The following table summarizes the gross carrying value, accumulated amortization and net carrying value of the Company’s indefinite life and finite life intangible assets:

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 for the six months ended June 30, 2025, or 2024.

The following table summarizes activity related to the Company’s mortgage servicing rights for the six months ended June 30, 2025:

The following is the estimated future expense for amortization of the finite life intangible assets for each of the next five years and thereafter:

On November 29, 2024 the Company amended and extended the multi-currency, sustainability-linked senior unsecured revolving credit facility (the “Revolving Credit Facility”). The Company increased the Revolving Credit Facility from $1,750,000 to $2,250,000 and extended for a 5-year term maturing November 29, 2029. 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 six months ended June 30, 2025, the weighted average interest rate on borrowings under the Revolving Credit Facility was 6.1% (2024 – 6.9%). The Revolving Credit Facility had $1,062,095 of available undrawn credit as at June 30, 2025 ($1,235,898 as at December 31, 2024). As at June 30, 2025, letters of credit in the amount of $19,219 were outstanding against the Revolving Credit Facility ($18,582 as at December 31, 2024). 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 with a carrying value of $543,127. A summary of the unsecured senior notes is provided in the table below:

The Senior Notes due 2028 and the Senior Notes due 2031 are each held by a group of institutional investors.

The Revolving Credit Facility, Senior Notes due 2028, and Senior Notes due 2031 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 June 30, 2025. The Company is limited from undertaking certain mergers, acquisitions and dispositions without prior approval.

9.	Mortgage warehouse credit facilities

The following table summarizes the Company’s mortgage warehouse credit facilities:

(1) SOFR in Facility B has a floor of 0.25%

Colliers Mortgage LLC (“Colliers Mortgage”) has warehouse credit facilities which are used exclusively for the purpose of funding warehouse mortgages receivable. The mortgage warehouse credit facilities are recourse only to Colliers Mortgage, are revolving and are secured by warehouse mortgages financed on the facilities.

On May 19, 2025, the Company amended Facility B to increase the borrowing capacity to $225,000.

In 2019, the Company entered into a structured accounts receivable facility (the “AR Facility”). Under 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 a third-party financial institution (the “Purchaser”).

On June 27, 2025, the Company renewed its AR Facility with two third-party financial institutions, with a term extending to June 26, 2026 and a capacity of $200,000. As of June 30, 2025, the Company’s draw under the AR Facility was $199,988.

All transactions under the AR Facility are accounted for as a true sale in accordance with ASC 860, Transfers and Servicing (“ASC 860”). Following the sale of the Receivables to the Purchaser, the Receivables are legally isolated from the Company and its wholly owned special purpose entities. The AR Facility is recorded as a sale of accounts receivable, and accordingly sold receivables are derecognized from the consolidated balance sheet. The Company continues to service, administer and collect the Receivables on behalf of the Purchaser, and recognizes a servicing liability in accordance with ASC 860. The Company has elected the amortization method for subsequent measurement of the servicing liability, which is assessed for changes in the obligation at each reporting date. As of June 30, 2025, 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; however, due to the revolving nature of the AR Facility, cash collected from the Company's customers is reinvested by the Purchaser monthly in new Receivable purchases under the AR Facility. As at June 30, 2025, the DPP was $116,616 (December 31, 2024 - $126,082) and was included in Prepaid expenses and other current assets on the Consolidated Balance Sheets. For the six months ended June 30, 2025, Receivables sold under the AR Facility were $884,887 and cash collections from customers on Receivables sold were $894,868, 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 June 30, 2025, the outstanding principal on trade accounts receivable, net of expected credit losses, sold under the AR Facility was $205,413; and the outstanding principal on contract assets, current and non-current, sold under the AR Facility was $147,378. See note 16 for fair value information on the DPP.

For the six months ended June 30, 2025, the Company recognized a loss related to Receivables sold of $20 (2024 - $71) 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 six months ended June 30, 2025, were $73,343.

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:

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:

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 June 30, 2025, was $958,240 (December 31, 2024 - $958,558). 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 June 30, 2025, approximately 7,530,000 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.

Stock options were anti-dilutive for the six months ended June 30, 2025 and dilutive for all other periods presented.

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

On February 28, 2024, the Company issued 2,479,500 Subordinate Voting Shares for gross proceeds of $300,019. The total proceeds, net of commissions and fees, were recorded in common shares.

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 June 30, 2025, there were 962,575 options available for future grants.

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

Stock option activity for the six months ended June 30, 2025 was as follows:

The amount of compensation expense recorded in the statement of earnings for the three and six months ended June 30, 2025 was $7,877 and $15,962 (2024 - $7,446 and $14,134). As of June 30, 2025, there was $44,503 of unrecognized compensation cost related to non-vested awards which is expected to be recognized over the next 4 years. During the six months ended June 30, 2025, the fair value of options vested was $440 (2024 - $759).

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.

During the three-month period ended June 30, 2025, the Company recorded stock-based compensation expense related to the PSUs of $1,276, and a recovery of $157 for the six-month period ended June 30, 2025. As at June 30, 2025, the estimated fair value of the PSUs is $34,146 and there is approximately $20,864 of total estimated unrecognized compensation expense related to the arrangement which are expected to be expensed over the next four years. As at June 30, 2025, 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 June 30, 2025, $13,282 is reported in Other liabilities on the Company’s consolidated balance sheets.

Income tax expense for the six months ended June 30, 2025, reflected an effective tax rate of 29.1% (2024 - 28.5%). The tax rates of both the current period and prior period were impacted by valuation allowances on losses incurred by certain subsidiaries and permanent non-deductible expenses.

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 June 30, 2025:

Equity securities, debt securities, mortgage derivative assets, interest rate swap assets and the deferred purchase price on the AR Facility were included in prepaid expenses and other current assets 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 six months ended June 30, 2025.

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 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:

Mortgage warehouse receivables

Mortgage warehouse receivables represent mortgage loans originated by the Company with commitments to sell to third party investors. Principal funded on mortgage loans plus gains attributable to the fair value of mortgage premiums and origination fees increase mortgage warehouse receivables and proceeds received from the sale of mortgage loans to third party investors reduce mortgage warehouse receivables. As at June 30, 2025, 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 a substantial majority 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 10 for information on the AR Facility.

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

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 June 30, 2025.

2022 IRS A, 2022 IRS B, 2023 IRS A and 2023 IRS B (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 June 30, 2025, unrealized loss of $95 (December 31, 2024 - $7,455) on the Designated IRSs were included in AOCI.

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 10.3%, with a weighted average of 9.8%). The wide range of discount rates is attributable to the level of risk related to economic growth factors combined with the length of the contingent payment periods; and the dispersion was driven by unique characteristics of the businesses acquired and the respective terms for these contingent payments. A 2% increase in the weighted average discount rate would reduce the fair value of contingent consideration by $500. See note 4 for discussion on contingent acquisition consideration.

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

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.

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 Mortgage 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 16, the Company accounts for these commitments as derivatives recorded at fair value.

Colliers Mortgage 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 June 30, 2025, the Company has funded and sold loans subject to such loss sharing obligations with an aggregate unpaid principal balance of approximately $6,196,000. (December 31, 2024 - $5,584,000) As at June 30, 2025, the loss reserve was $13,152 (December 31, 2024 - $13,556) and was included within Other liabilities on the consolidated balance sheets.

Pursuant to its licenses with Fannie Mae, Ginnie Mae and the Department of Housing and Urban Development, Colliers Mortgage 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 Mortgage fails to maintain appropriate capital adequacy, the licensor reserves the right to terminate the Company’s servicing authority for all or some of the portfolio. As at June 30, 2025, Colliers Mortgage was in compliance with all such requirements.

Disaggregated revenue

Colliers has disaggregated its revenue from contract with customers by type of service and reporting segment as presented in the following table. Engineering revenue includes engineering, design and project management activities.
