TORONTO, Feb. 08, 2024 (GLOBE NEWSWIRE) -- Colliers International Group Inc. (NASDAQ and TSX: CIGI) (“Colliers” or the “Company”) today announced operating and financial results for the fourth quarter and year ended December 31, 2023. All amounts are in US dollars.

For the seasonally strong fourth quarter ended December 31, 2023, revenues were $1.24 billion, up 1% (flat in local currency) and adjusted EBITDA (note 1) was $198.4 million, down 2% (down 3% in local currency) versus the prior year quarter. Adjusted EPS (note 2) was $2.00, relative to $2.31 in the prior year quarter. Fourth quarter adjusted EPS would have been approximately $0.02 lower excluding foreign exchange impacts. GAAP operating earnings were $132.6 million as compared to $103.8 million in the prior year quarter. GAAP diluted net earnings per share were $1.42 versus $0.51 in the prior year quarter on a reduction in acquisition-related costs and lower non-controlling interest. The fourth quarter GAAP diluted net earnings per share would have been approximately $0.02 lower excluding changes in foreign exchange rates.

For the full year ended December 31, 2023, revenues were $4.34 billion, down 3% (3% in local currency) and adjusted EBITDA (note 1) was $595.0 million, down 6% (6% in local currency) versus the prior year. Adjusted EPS (note 2) was $5.35, relative to $6.99 in the prior year. Adjusted EPS for the year would have been approximately $0.02 lower excluding foreign exchange impacts. GAAP operating earnings were $300.9 million as compared to $332.5 million in the prior year. GAAP diluted net earnings per share were $1.41 compared to earnings per share of $1.05 in the prior year, with the prior year impacted by a loss on disposal of certain operations including Russia. The 2023 GAAP diluted net earnings per share would have been approximately $0.02 lower excluding changes in foreign exchange rates.

“In the fourth quarter, Colliers experienced robust revenue growth in its high-value recurring service lines. Outsourcing & Advisory and Investment Management delivered increases of 10% and 6%, respectively. Over the course of the year, these services achieved even greater growth, with respective increases of 11% and 28%,” said Jay S. Hennick, Chairman & CEO of Colliers.

“Colliers has strategically transformed into a highly diversified professional services company by expanding its operations to include additional recurring revenue streams such as Investment Management and Engineering and Design. Today, more than 70% of our earnings come from recurring services, which provide our business greater stability and predictability, setting us apart from our competitors.”

“Throughout the year, we observed industry-wide declines in transaction volumes, which had an impact on our Capital Markets and, to a lesser extent, Leasing revenues. However, we anticipate a return to higher transaction velocity in the latter half of 2024 as interest rates and credit conditions stabilize.”

“With our nearly 30-year track record of creating substantial shareholder value, coupled with the expectation of increased transactional revenue later this year and a robust pipeline of new opportunities, we are more excited about the future than ever,” he concluded.

(1) Investment Management local currency revenues, excluding pass-through carried interest, were up 4% and 38% for the three and twelve months ended December 31, 2023, respectively.

For the fourth quarter, consolidated revenues were flat on a local currency basis. The market-driven transaction slowdown in Capital Markets and, to a lesser extent, Leasing was offset by solid growth in Outsourcing & Advisory and Investment Management. Consolidated internal revenues measured in local currencies declined 2% (note 3) versus the prior year quarter.

For the year ended December 31, 2023, consolidated revenues decreased 3% on a local currency basis on lower Capital Markets and, to a lesser extent, Leasing activity partly offset by strong growth in Investment Management and Outsourcing & Advisory. Consolidated internal revenues measured in local currencies were down 8% (note 3).

Segmented Fourth Quarter Results
Revenues in the Americas region totalled $677.9 million, flat (down 1% in local currency) versus $678.9 million in the prior year quarter. The decline was driven by lower Capital Markets and Leasing activity partly offset by higher Outsourcing & Advisory revenues as well as the favourable impact of recent acquisitions. Adjusted EBITDA was $78.8 million, down 5% (5% in local currency) relative to the prior year quarter due to declines in higher margin transactional revenues. GAAP operating earnings were $53.3 million, relative to $52.0 million in the prior year quarter.

EMEA region revenues totalled $235.7 million, up 3% (down 2% in local currency) compared to $228.3 million in the prior year quarter, attributable to lower Capital Markets activity, particularly in Germany and the Nordics, partly offset by growth in Outsourcing & Advisory. Adjusted EBITDA was $35.7 million, flat (down 5% in local currency) compared to $35.9 million in the prior year quarter. GAAP operating earnings were $28.9 million compared to $30.4 million in the prior year quarter.

Revenues in the Asia Pacific region totalled $192.4 million compared to $193.6 million in the prior year quarter, down 1% (flat in local currency), due to lower Capital Markets activity offset by recent acquisitions. Adjusted EBITDA was $32.3 million, down 6% (5% in local currency) primarily on changes in service mix. GAAP operating earnings were $26.0 million, versus $29.0 million in the prior year quarter.

Investment Management revenues were $129.1 million relative to $121.3 million in the prior year quarter, up 6% (6% in local currency). Passthrough revenues (from historical carried interest) were $6.2 million versus $3.6 million in the prior year quarter. Excluding the impact of carried interest, revenue was up 5% (4% in local currency) driven by management fee growth from increased assets under management (“AUM”). Adjusted EBITDA was $53.8 million, up 1% (1% in local currency) compared to the prior year quarter. GAAP operating earnings were $41.5 million in the quarter, versus a GAAP operating loss of $18.8 million in the prior year quarter which was impacted by contingent acquisition consideration expense related to recent acquisitions. AUM was $98.2 billion as of December 31, 2023 compared to $97.7 billion as of December 31, 2022.

Unallocated global corporate costs as reported in Adjusted EBITDA were $2.4 million in the fourth quarter, relative to $3.5 million in the prior year quarter. The corporate GAAP operating loss for the quarter was $17.1 million, versus earnings of $11.2 million in the fourth quarter of 2022.

Segmented Full Year Results
Revenues in the Americas region totalled $2.51 billion for the year compared to $2.76 billion in the prior year, down 9% (9% in local currency). The revenue decline was largely driven by market conditions in Capital Markets and, to a lesser extent, Leasing. The decline was partly offset by internal growth in Outsourcing & Advisory revenues and the favourable impact of recent acquisitions. Adjusted EBITDA was $270.9 million, down 18% (18% in local currency) from $332.3 million in the prior year, impacted by (i) changes in service mix; and (ii) an $11.4 million gain on the termination of a lease which favourably impacted the prior year. GAAP operating earnings were $174.6 million, versus $254.4 million in 2022.

EMEA region revenues were $726.9 million for the full year compared to $715.1 million in the prior year, up 2% (down 1% in local currency). Local currency revenue mix shifted significantly, with Capital Markets and Leasing lower due to difficult macroeconomic conditions, almost fully offset by growth in Outsourcing & Advisory (including recent acquisitions). Adjusted EBITDA was $38.4 million, down 44% (50% in local currency) versus $68.5 million in the prior year on significantly lower higher-margin Capital Markets revenues. GAAP operating earnings were $5.5 million as compared to $9.9 million in 2022.

The Asia Pacific region generated revenues of $610.3 million for the year, which were flat (up 4% in local currency) compared to $608.5 million in the prior year. Both Leasing and Outsourcing & Advisory revenues (including recent acquisitions) were up, partly offset by a continued decline in Capital Markets activity consistent with the market conditions in the region. Adjusted EBITDA was $79.2 million, down 7% (4% in local currency) versus $85.1 million in the prior year. GAAP operating earnings were $62.7 million, versus $72.3 million in the prior year.

Investment Management revenues were $487.5 million compared to $378.9 million in the prior year, up 29% (28% in local currency). Pass-through revenue from historical carried interest was $6.8 million in the current year, versus $30.3 million in the prior year. Excluding the impact of pass-through revenue, revenues were up 38% (38% in local currency) and were positively impacted by (i) acquisitions and (ii) fundraising across all investment strategies which led to increased management fees. Adjusted EBITDA was $213.9 million, up 47% (46% in local currency), relative to $146.0 million in the prior year. GAAP operating earnings were $103.1 million, versus $37.1 million in 2022.

Unallocated global corporate costs as reported in Adjusted EBITDA were $7.4 million in 2023, relative to $1.4 million in the prior year, with the difference primarily attributable to foreign exchange gains in the prior year. The corporate GAAP operating loss was $45.0 million, relative to $41.1 million in 2022.

Outlook for 2024
For 2024, the Company expects Capital Markets and Leasing conditions to remain challenging in the first half of the year followed by year-over-year growth in the second half, with market sentiment improving and interest rates and credit conditions stabilizing. Outsourcing & Advisory revenue growth is expected to remain resilient. Investment Management revenues are expected to grow in line with fundraising, which is expected to improve relative to 2023.

The outlook for 2024 is as follows:

Measure	Actual 2023	Outlook for 2024
Revenue growth	-3%	+5% to +10%
Adjusted EBITDA growth	-6%	+5% to +15%
Adjusted EPS growth	-23%	+10% to +20%

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, health, social and related factors. Continued interest rate volatility and/or lack of credit availability for commercial real estate transactions could materially impact the outlook.

Notes
Non-GAAP Measures
1. Reconciliation of net earnings to adjusted EBITDA

Adjusted EBITDA is defined as net earnings, adjusted to exclude: (i) income tax; (ii) other expense (income); (iii) interest expense; (iv) loss on disposal of operations; (v) depreciation and amortization, including amortization of mortgage servicing rights (“MSRs”); (vi) gains attributable to MSRs; (vii) acquisition-related items (including contingent acquisition consideration fair value adjustments, contingent acquisition consideration-related compensation expense and transaction costs); (viii) restructuring costs and (ix) stock-based compensation expense. 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 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.

2. 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 as calculated under the “if-converted” method, adjusted for the effect, after income tax, of: (i) the non-controlling interest redemption increment; (ii) loss on disposal of operations; (iii) amortization expense related to intangible assets recognized in connection with acquisitions and MSRs; (iv) gains attributable to MSRs; (v) acquisition-related items; (vi) restructuring costs and (vii) stock-based compensation expense. 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.

Similar to GAAP diluted EPS, Adjusted EPS is calculated using the “if-converted” method of calculating earnings per share in relation to the Convertible Notes, which were issued on May 19, 2020 and fully converted or redeemed by June 1, 2023. As such, the interest (net of tax) on the Convertible Notes is added to the numerator and the additional shares issuable on conversion of the Convertible Notes are added to the denominator of the earnings per share calculation to determine if an assumed conversion is more dilutive than no assumption of conversion. The “if-converted” method is used if the impact of the assumed conversion is dilutive. The “if-converted” method is dilutive for the adjusted EPS calculation for all periods where the Convertible Notes were outstanding.

3. 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 of 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.

4. 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. Percentage revenue variances presented on an internal growth basis are 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.

5. 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.

6. Adjusted EBITDA from recurring revenue percentage

Adjusted EBITDA from recurring revenue percentage is computed on a trailing twelve-month basis and represents the proportion of adjusted EBITDA (note 1) that is derived from Outsourcing & Advisory and Investment Management service lines. Both 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.

Notes to Condensed Consolidated Statements of Earnings
(1)	Acquisition-related items include contingent acquisition consideration fair value adjustments, contingent acquisition consideration-related compensation expense and transaction costs.
(2)	Diluted EPS is calculated using the “if-converted” method of calculating earnings per share in relation to the Convertible Notes, which were issued on May 19, 2020 and fully converted or redeemed by June 1, 2023. As such, the interest (net of tax) on the Convertible Notes is added to the numerator and the additional shares issuable on conversion of the Convertible Notes are added to the denominator of the earnings per share calculation to determine if an assumed conversion is more dilutive than no assumption of conversion. The “if-converted” method is used if the impact of the assumed conversion is dilutive. The “if-converted” method was anti-dilutive for the year ended December 31, 2022.
(3)	See definition and reconciliation above.

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. Percentage revenue variances presented on an internal growth basis are 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. 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. 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. Recurring revenue percentage Recurring revenue percentage is computed on a trailing twelve - month basis and represents the proportion that is derived from Outsourcing & Advisory and Investment Management service lines. Both these service lines represent medium to long - term duration revenue streams that are either contractual or repeatable in nature. Revenue for this purpose incorporates the expected full year impact of acquisitions and dispositions. Adjusted EBITDA from recurring revenue percentage Adjusted EBITDA from recurring revenue percentage is computed on a trailing twelve - month basis and represents the proportion of adjusted EBITDA that is derived from Outsourcing & Advisory and Investment Management service lines. Both 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 calculated for our debt agreement covenant calculation purposes, incorporating the expected full year impact of business acquisitions and dispositions.
