Colliers Reports First Quarter Results

2026 starts with solid momentum across all service lines

TORONTO, Canada, May 5, 2026 - Colliers International Group Inc. (NASDAQ and TSX: CIGI) ("Colliers" or the "Company") today announced financial results for the first quarter ended March 31, 2026. All amounts are in US dollars.

First quarter consolidated revenues were $1.31 billion, up 15% (12% in local currency), net revenues were $1.15 billion, up 16% (12% in local currency) and Adjusted EBITDA (note 2) was $124.8 million, up 8% (8% in local currency) compared to the prior year

quarter. Consolidated internal revenue growth measured in local currencies was 7% (note 5) versus the prior year quarter. Adjusted EPS (note 3) was $0.91, an increase of 5% over the prior year quarter. Adjusted EPS was not significantly impacted by changes in foreign exchange rates. GAAP operating earnings were $35.0 million compared to $31.6 million in the prior year quarter. The GAAP diluted net loss per share was $0.47, compared to $0.08 in the prior year quarter. First quarter GAAP diluted net loss per share was not significantly impacted by changes in foreign exchange rates.

The Company generated approximately 70% of its earnings from resilient businesses - Engineering, Project Management, Investment Management, Property Management, Loan Servicing, and Valuation & Advisory (note 8). Free cash flow (note 4) was

$246.7 million for the trailing twelve-month period, slightly below the Company's target range, as a result of working capital movements during the first quarter.

"Colliers delivered a strong start to 2026, demonstrating the strength and durability of our diversified professional services and investment management platform. We executed to plan in a still-uneven operating environment, with continued momentum in our resilient businesses and ongoing improvement in Commercial Real Estate transaction activity. Importantly, our results underscore the platform we've built - a global business designed to perform through every stage of the economic cycle. During the quarter, we strengthened our leadership team to capitalize on expanding opportunities across Commercial Real Estate and Engineering. We enhanced our financial flexibility with $400 million of long-term debt financing and we extended our revolving credit facility - positioning us to integrate the acquisition of Ayesa Engineering, which we expect will close later this quarter. Our world-class leadership team remains focused on delivering durable growth and long-term shareholder value," said Jay S. Hennick, Global Chairman and CEO.

The Company has realigned its Commercial Real Estate and Engineering segments to reflect the new management reporting lines under Christian Mayer and Elias Mulamoottil 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. Institutional project management operations remain in the Engineering segment. Recast historical segment data can be found at corporate.colliers.com. There were no changes to the Investment Management or Corporate segments.

Commercial Real Estate revenues for the seasonally slow first quarter totalled $841.2 million, up 14% (up 11% in local currency) versus the prior year quarter. Net revenues were $736.3 million, up 16% (up 13% in local currency). 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 on continued strength in industrial and office asset classes. Taken together, transactional services were up 25% over the prior year showing meaningful recovery. Outsourcing revenues (including property management, valuation & advisory, loan servicing and local project management) were up modestly. Adjusted EBITDA was $46.2 million, up 18% (20% in local currency) versus the prior year quarter. The net margin increased on operating leverage from higher transactional revenues, partially offset by continued strategic investments in recruiting across the segment. The GAAP operating earnings were $16.5 million, relative to

$13.8 million in the prior year quarter.

Engineering revenues totalled $336.8 million, up 23% (18% in local currency) compared to the prior year quarter. Net revenues (excluding subconsultant and other pass-through costs) were $284.3 million, up 18% (13% in local currency) driven by a combination of recent acquisitions and solid internal growth. Adjusted EBITDA was $26.9 million, up 12% (9% in local currency) over the prior year quarter, with the net margin down slightly on lower utilization in certain end-markets. The GAAP operating earnings were $2.5 million relative to a loss of $3.3 million in the prior year quarter.

Investment Management revenues were $135.3 million, up 7% (6% in local currency) relative to the prior year quarter. Net revenues (excluding pass-through performance fees) 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% (9% in local currency) compared to the prior year quarter, reflecting planned ongoing investments in global fundraising as well as streamlining and integration initiatives to unify the business under the Harrison Street Asset Management ("HSAM") brand, which are expected to continue for the next two quarters. These initiatives are intended to support the continued growth and scaling of HSAM, with long-standing, cycle-tested expertise and a consistent track record of success across its diverse investment strategies. GAAP operating earnings were $15.4 million in the quarter versus $32.9 million in the prior year quarter. Total assets under management were $109.3 billion as of March 31, 2026, up 9% from March 31, 2025.

Unallocated global corporate Adjusted EBITDA was $1.2 million, compared to a cost of $2.2 million in the prior year quarter. The corporate GAAP operating earnings were $0.7 million compared to a cost of $11.9 million in the prior year quarter.

The Company's outlook for 2026 remains unchanged and includes the impact of Ayesa Engineering, which is expected to close in late May. The outlook drivers by segment are also unchanged and are described in the accompanying earnings call presentation.

The financial outlook is based on the Company's best available information as of the date of this press release, and remains subject to change based on numerous macroeconomic, geopolitical, international trade, health, social and related factors.

Non-GAAP Measures

2. Reconciliation of net earnings to Adjusted EBITDA

   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.

   Adjusted EBITDA	$	124,803	$	116,044

3. Reconciliation of net earnings and diluted net earnings per common share to adjusted net earnings and Adjusted EPS

   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.

4. Reconciliation of net cash flow from operations to free cash flow

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

   Three months ended
   March 31
   (in thousands of US$)		2026		2025
   Net cash used by operating activities	$	(187,426)	$	(84,476)
   Contingent acquisition consideration paid		2,970		2,268
   Purchases of fixed assets		(18,296)		(14,654)
   Cash collections on AR Facility deferred purchase price		51,315		48,421
   Distributions paid to non-controlling interests	(11,122)		(8,458)
   Free cash flow	$	(162,559)	$	(56,899)

   Add: Free cash flow for three months ended March 31, 2026		(162,559)
   Less: Free cash flow for three months ended March 31, 2025	56,899
   Trailing twelve months ended March 31, 2026 free cash flow	$	246,666

5. Local currency revenue and Adjusted EBITDA growth rate and internal revenue growth rate measures

   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.

6. Assets under management

   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.

7. Fee paying assets under management

   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.

8. Adjusted EBITDA from resilient revenue percentage

Adjusted EBITDA from resilient revenue percentage is computed on a trailing twelve-month basis and represents the proportion of Adjusted EBITDA (note 2) that is derived from Engineering, Outsourcing and Investment Management service lines. All these service lines represent medium to long-term duration revenue streams that are either contractual or repeatable in nature. Adjusted EBITDA for this purpose is calculated in the same manner as for our debt agreement covenant calculation purposes, incorporating the expected full year impact of business acquisitions and dispositions.
