Colliers International Reports First Quarter Results

Solid start to 2019 paves the way for another strong year of growth

Operating highlights:

(in millions of US$, except EPS)	2019		2018
Revenues	$	635.1	$	552.5
Adjusted EBITDA (note 1)		43.6		36.1

TORONTO, April 26, 2019 (GLOBE NEWSWIRE) -- Colliers International Group Inc. (NASDAQ: CIGI) (TSX: CIGI) today reported operating and financial results for its first quarter ended March 31, 2019. All amounts are in US dollars.

Revenues for the seasonally slow first quarter were $635.1 million, a 15% increase (19% in local currency) relative to the same quarter in the prior year, Adjusted EBITDA (note 1) was $43.6 million, up 21% (22% in local currency) and Adjusted EPS (note 2) was $0.51, a 13% increase versus the prior year quarter. First quarter adjusted EPS would have been approximately $0.01 higher excluding foreign exchange impacts. GAAP operating earnings were $13.4 million, relative to $15.7 million reported in the prior year period, primarily because of significant incremental amortization of intangible assets related to the acquisition of Harrison Street Real Estate Capital, LLC (“Harrison Street”) in July 2018. GAAP diluted net earnings per common share was $0.04 for the quarter, versus $0.13 per share for the same quarter a year ago. First quarter GAAP EPS would have been approximately $0.01 higher excluding foreign exchange impacts.

“Colliers delivered a solid start to 2019. We remain confident in our outlook for 2019 and are pleased with the impact Harrison Street is having on the growth and diversification of our business,” said Jay S. Hennick, Chairman and CEO of Colliers International. “Following a record year of acquisitions last year, we have completed three acquisitions so far this year, adding the market leader in Virginia with 340 professionals, our former affiliate and one of the top players in the vibrant growth market of Charlotte, North Carolina as well as our former affiliate in Sweden, further strengthening our European platform. Finally, earlier this month, we extended our $1 billion revolving credit facility to 2024 and established a structured accounts receivable facility, diversifying our capital structure and reducing borrowing costs. With a strong balance sheet, disciplined growth strategy, proven track record and greater diversification, Colliers is well positioned to deliver another strong year of growth in 2019,” he concluded.

Consolidated Revenues by Line of Service

	Three months ended
(in thousands of US$)	March 31				Growth		Growth
(LC = local currency)	2019		2018		in US$ %		in LC %
Outsourcing & Advisory	$	258,384	$	239,771	8	%	13	%
Lease Brokerage		181,783		167,691	8	%	11	%
Sales Brokerage		151,865		142,277	7	%	10	%
Investment Management		43,091		2,734	NM		NM
Total revenues	$	635,123	$	552,473	15	%	19	%

Consolidated revenues for the first quarter grew 19% on a local currency basis, with a significant contribution from Harrison Street in Investment Management, solid internal growth and recent acquisitions. Consolidated internal revenue growth in local currencies was 8% (note 3), led by Outsourcing & Advisory in the EMEA and Asia Pacific regions.

Segmented First Quarter Results
Americas region revenues totalled $358.8 million for the first quarter compared to $328.5 million in the prior year quarter, up 11% on a local currency basis. Revenue growth was comprised of 7% contribution from recent acquisitions and 4% internal growth primarily in Lease Brokerage and Outsourcing & Advisory. Adjusted EBITDA was $26.2 million, relative to $26.5 million in the prior year quarter with the margin impacted by investments in recruiting relative to the prior year as well as revenue mix. GAAP operating earnings were $16.2 million, relative to $20.0 million in the prior year quarter.

EMEA region revenues totalled $120.5 million for the first quarter compared to $113.0 million in the prior year quarter, up 15% on a local currency basis, comprised of 13% internal growth and 2% from recent acquisitions. Outsourcing & Advisory, especially project management, as well as Sales Brokerage, contributed significantly to internal revenue growth. Adjusted EBITDA was a loss of $2.5 million, versus breakeven in the prior year quarter, impacted by incremental planned investments in additional revenue producers. The GAAP operating loss was $10.1 million for the quarter, relative to a loss of $9.1 million in the prior year quarter.

Asia Pacific region revenues totalled $112.3 million for the first quarter compared to $107.8 million in the prior year quarter, up 11% on a local currency basis. Revenue growth was comprised of 9% internal growth primarily in Outsourcing & Advisory, and 2% growth from recent acquisitions. Adjusted EBITDA was $10.9 million versus $11.2 million in the prior year quarter, with the margin impacted by revenue mix favouring lower margin recurring services. GAAP operating earnings were $9.2 million for the first quarter, relative to $9.4 million in the prior year quarter.

The Investment Management segment is comprised of Harrison Street (acquired in July 2018), and the Company’s existing European investment management business which was previously reported within the EMEA segment. Investment Management revenues for the first quarter were $43.1 million, of which $11.2 million represented pass-through revenue from historical carried interest. The carried interest recognized was payable to former owners of Harrison Street and certain long-serving employees, affecting reported margin but having no impact on earnings. Adjusted EBITDA was $10.2 million. Operating earnings were $3.6 million in the quarter because of the significant increase in acquisition-related intangible asset amortization. Assets under management stood at $26.7 billion as of March 31, 2019.

Global corporate costs as reported in Adjusted EBITDA were $1.3 million in the first quarter, relative to $1.1 million in the prior year period. The corporate GAAP operating loss for the first quarter was $5.5 million, relative to a loss of $4.1 million in the prior year period.

Conference Call
Colliers will be holding a conference call on Friday, April 26, 2019 at 11:00 a.m. Eastern Time to discuss the quarter’s results. The call, as well as a supplemental slide presentation, will be simultaneously web cast and can be accessed live or after the call at corporate.colliers.com the Events section.

Adoption of New Lease Accounting Standard
On January 1, 2019, the Company adopted FASB Accounting Standard Codification Topic 842, Leases (“ASC 842”). ASC 842 requires the recognition of operating lease right-of-use assets and lease liabilities for virtually all premise and equipment leases on the consolidated balance sheet, with no impact on earnings. The Company adopted ASC 842 effective January 1, 2019 without adjusting comparative periods and recorded a $278.7 million right-of-use asset and corresponding $316.9 million lease liability as of March 31, 2019.

The recognition of the lease liability did not impact the Company’s financial covenants under its revolving credit facility or its senior notes, since the underlying debt agreements include provisions that nullify the impact of changes in accounting standards.

Structured Accounts Receivable Facility
In April 2019, the Company entered into a structured accounts receivable facility (the “AR Facility”) with committed availability of US$125 million to further diversify its capital structure and reduce borrowing costs. Proceeds from the AR Facility will be used to repay outstanding indebtedness under the Company’s revolving credit facility. The Company expects that the AR Facility will be off-balance sheet, resulting in a reduction in accounts receivable and long-term debt.

Notes
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) depreciation and amortization; (v) acquisition-related items; (vi) restructuring costs and (vii) 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.

Adjusted EBITDA	$	43,571		$	36,140

2. Reconciliation of net earnings and diluted net earnings (loss) per common share to adjusted net earnings and adjusted earnings per share:

Adjusted earnings per share is defined as diluted net earnings (loss) per common share, adjusted for the effect, after income tax, of: (i) the non-controlling interest redemption increment; (ii) amortization expense related to intangible assets recognized in connection with acquisitions; (iii) acquisition-related items; (iv) restructuring costs and (v) 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 earnings per share is not a recognized measure of financial performance under GAAP, and should not be considered as a substitute for diluted net earnings per share, 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 (loss) per share to adjusted earnings per share appears below.

3. Local currency revenue growth rate and internal revenue growth

Percentage revenue 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 acquired entities were owned for the entire current period as well as the entire prior period. Revenue from acquired entities is estimated based on the operating performance of each acquired entity for the year prior to the acquisition date. Revenue from pass-through carried interest is excluded. 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, acquisitions and pass-through carried interest. The consolidated local currency internal revenue growth rate for the quarter ended March 31, 2019 would have been 9% if carried interest were included. Since these revenue growth rate measures are not calculated under GAAP, they may not be comparable to similar measures used by other issuers.

4. 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 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.
