TORONTO, April 25, 2018 (GLOBE NEWSWIRE) --  FirstService Corporation (TSX:FSV) (NASDAQ:FSV) today reported strong results for its first quarter ended March 31, 2018. All amounts are in US dollars.

Revenues for the first quarter were $426.5 million, up 12% relative to the same quarter in the prior year, Adjusted EBITDA (note 1) increased 26% to $25.4 million, and Adjusted EPS (note 2) was $0.25, representing 56% growth over the prior year quarter. GAAP Operating Earnings were $11.1 million, relative to $9.0 million in the prior year period. GAAP diluted earnings per share was $0.17 per share in the quarter, versus $0.12 in the same quarter a year ago.

“We are pleased to report very strong financial results for the first quarter, reflecting a continuation of the focused execution and healthy market fundamentals that have driven our performance for the past several quarters,” said Scott Patterson, Chief Executive Officer of FirstService. “With a favourable housing and home improvement outlook and recent tuck-under acquisition activity, we have solid momentum towards achieving our growth objectives for the year.”

Impact of New Revenue Recognition Standard
On January 1, 2018, as a result of required changes under U.S. GAAP, FirstService adopted the new accounting standard ASC 606, Revenue from Contracts with Customers and all the related amendments (“New Revenue Standard”) to all contracts using the full retrospective method. Our prior year 2017 financial results as reported herein have been recast in accordance with the New Revenue Standard to provide a consistent comparison to current year results. The impact is confined to our franchised operations within our FirstService Brands segment, particularly as it relates to the timing and recognition of franchise fees, as well as the gross revenue recognition of marketing fund fees. As a result, the effect of the New Revenue Standard on the prior year first quarter results was an increase of $4.4 million to our consolidated revenues, a decrease of $0.6 million to our consolidated Adjusted EBITDA, resulting in a 20 basis points decrease to our consolidated Adjusted EBITDA margin, and a decrease of $0.01 to our Adjusted EPS. The same $4.4 million increase to our FirstService Brands revenues and $0.6 million decrease to our FirstService Brands Adjusted EBITDA resulted in an 80 basis point decrease to our FirstService Brands Adjusted EBITDA margin for our recast segmented 2017 first quarter results.

Segmented Quarterly Results
FirstService Residential revenues were $284.1 million for the first quarter, up 7% versus the prior year quarter. Organic growth accounted for half of this increase, with performance relatively balanced across our services and geographies. Adjusted EBITDA for the quarter was $17.5 million, up from $14.4 million in the prior year period. GAAP Operating earnings were $11.4 million, up from $9.1 million versus the prior year period. Operating margin expansion was partially driven by ongoing efficiencies, and further amplified during our seasonally weakest first quarter by the contribution of recent acquisitions with a non-seasonal cash flow profile.

FirstService Brands revenues for the first quarter totalled $142.3 million, up 24% relative to the prior year period. The revenue increase was comprised of 10% organic growth, with the balance coming from tuck-under acquisitions within the past year at our California Closets and Paul Davis Restoration company-owned platforms. During the quarter, organic growth was robust and broad-based across all of our company-owned platforms and franchised operations. Adjusted EBITDA was $11.2 million, a significant increase over the $8.3 million in the prior year quarter. GAAP Operating Earnings were $5.1 million, versus $3.9 million in the prior year quarter. Margin improvement was attributable to the addition of recent, non-seasonal company-owned operations in our seasonally lowest quarter, as well as operating leverage from certain service lines which benefited from strong top-line growth.

Corporate costs, as presented in Adjusted EBITDA, were $3.2 million in the first quarter, relative to $2.6 million in the prior year period. On a GAAP basis, corporate costs for the quarter were $5.4 million, relative to $4.1 million in the prior year period.

Notes
1. Reconciliation of net earnings to Adjusted EBITDA:

Adjusted EBITDA is defined as net earnings, adjusted to exclude: (i) income tax; (ii) other (income) expense; (iii) interest expense; (iv) depreciation and amortization; (v) acquisition-related items; and (vi) stock-based compensation expense. The Company uses adjusted EBITDA to evaluate its own operating performance, its ability to service debt, and as an integral part of its planning and reporting systems. Additionally, this measure is used in conjunction with discounted cash flow models to determine the Company’s overall enterprise valuation and to evaluate acquisition targets. Adjusted EBITDA is presented as a supplemental measure because the Company believes such a measure is useful to investors as a reasonable indicator of operating performance, due to the low capital intensity of the Company’s service operations. The Company believes 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. The Company’s 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 (loss) to adjusted EBITDA appears below.

2. Reconciliation of net earnings and net earnings per 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) acquisition-related items; (iii) amortization expense related to intangible assets recognized in connection with acquisitions; (iv) stock-based compensation expense; and (v) a stock-based compensation tax adjustment related to a US GAAP change. The Company believes 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, as determined in accordance with GAAP. The Company’s 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.
