ROSWELL, Ga. — (BUSINESS WIRE) — SiteOne Landscape Supply, Inc. (the “Company” or “SiteOne”) (NYSE: SITE) announced earnings for its fourth quarter and full fiscal year ended January 1, 2017 (“Fiscal 2016”).

“We are very pleased with the performance and growth that we delivered to finish 2016, despite a difficult comparison to the fourth quarter of 2015. Overall, during our first year as a public company, we built a significant foundation for the future while achieving double digit net sales growth, solid expansion of our gross margin and Adjusted EBITDA margin, excellent Adjusted EBITDA growth and strong cash flow,” said Doug Black, SiteOne Chief Executive Officer. “We are off to a good start for 2017 as our market drivers remain healthy, our organic growth initiatives gain momentum and our acquisition efforts continue with four transactions completed so far this year. We are still in the early innings of our development as a company and we remain excited about the long-term opportunity for SiteOne to create significant value for all of our stakeholders.”

Fourth Quarter 2016 Results

Net sales for the fourth quarter of 2016 increased to $361.8 million, or 6%, compared to $339.8 million for the prior-year period. Organic Sales decreased 3% overall, but increased 3% after adjusting for the four fewer Selling Days during the quarter in 2016 compared to the prior year period. Acquisitions contributed approximately $30 million in sales or 9% to our overall growth for the quarter.

Gross profit increased to $111.8 million, or 7%, compared to $104.6 million for the prior-year period. Gross margin improved by 10 bps to 30.9% for the fourth quarter 2016.

Selling, general and administrative expenses (“SG&A”) in the fourth quarter increased to $116.2 million from $110.7 million in the same period last year, primarily reflecting the impact from acquisitions. SG&A as a percent of net sales decreased to 32.1%, an improvement of 50 basis points compared to the same period last year.

Net loss for the fourth quarter was $5.6 million, compared to a net loss of $5.9 million during the same period from the prior year.    

Adjusted EBITDA decreased to $11.2 million for the fourth quarter, compared to $11.9 million for the prior-year period.

Full Year 2016 Results

Net sales for Fiscal 2016 increased to $1.65 billion, or 14%, compared to $1.45 billion for the prior fiscal year (“Fiscal 2015”). Organic Sales increased 3% for Fiscal 2016 compared to Fiscal 2015, 4% after adjusting for the fewer Selling Days in Fiscal 2016. Organic Sales growth was driven by the irrigation, nursery, outdoor lighting, hardscapes and landscape accessories categories, which together grew over 7% on an Organic Daily Sales basis. These products continue to benefit from strength in residential and commercial construction. Organic Sales for agronomic products like fertilizer and control products were flat on a daily basis. Acquisitions contributed $157 million in net sales or 11% to our overall growth for Fiscal 2016.

Gross profit for Fiscal 2016 increased to $515.7 million, or up 20%, compared to $429.1 million for the prior year. Gross margin for the year improved by 170 bps to 31.3% compared to 29.6% in Fiscal 2015. Operational improvements in category management and pricing were the primary contributors.

Selling, general and administrative expenses (“SG&A”) for the year increased to $446.5 million from $373.3 million in Fiscal 2015. SG&A as a percent of net sales increased to 27.1% from 25.7% in Fiscal 2015. The increase in SG&A was attributable to our acquisitions, transition costs associated with the IPO, secondary and debt refinancing, and investments in personnel to support our growth.

Net income for Fiscal 2016 was $30.6 million, compared to net income of $28.9 million for Fiscal 2015. The increase in net income for the year was attributable to the sales growth both organically and through acquisition, and gross margin expansion offset by increased interest expense and higher SG&A costs.

For the year, Adjusted EBITDA increased 26% to $134.3 million, compared to $106.5 million in Fiscal 2015. The Adjusted EBITDA margin expanded by 80 basis points to 8.1%, compared to Fiscal 2015.

Net debt, calculated as long-term debt (net of issuance costs and discounts) plus capital leases, net of cash and cash equivalents on our balance sheet as of January 1, 2017, was $370.2 million. Net debt to Adjusted EBITDA for the last twelve months was 2.8 times, a reduction from 3.3 times last year as reported on a pro-forma basis in our Form S-1 Registration Statement filed in connection with our IPO.

Outlook

For 2017, we expect Adjusted EBITDA to be in the range of $155 million to $165 million.

Reconciliation for the forward-looking full-year 2017 Adjusted EBITDA outlook is not being provided, as the Company does not currently have sufficient data to accurately estimate the variables and individual adjustments for such reconciliation.

Forward-Looking Statements

This release contains “forward-looking statements” within the meaning of the Federal Private Securities Litigation Reform Act of 1995. Forward-looking statements may include, but are not limited to, statements relating to our 2017 Adjusted EBITDA outlook. Some of the forward-looking statements can be identified by the use of terms such as “may,” “intend,” “might,” “will,” “should,” “could,” “would,” “expect,” “believe,” “estimate,” “anticipate,” “predict,” “project,” “potential,” or the negative of these terms, and similar expressions. You should be aware that these forward-looking statements are subject to risks and uncertainties that are beyond our control. Further, any forward-looking statement speaks only as of the date on which it is made, and we undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which it is made or to reflect the occurrence of anticipated or unanticipated events or circumstances. New factors emerge from time to time that may cause our business not to develop as we expect, and it is not possible for us to predict all of them. Factors that may cause actual results to differ materially from those expressed or implied by the forward-looking statements include, but are not limited to, the following: cyclicality in residential and commercial construction markets; general economic and financial conditions; weather conditions, seasonality and availability of water to end-users; laws and government regulations applicable to our business that could negatively impact demand for our products; public perceptions that our products and services are not environmentally friendly; competitive industry pressures; product shortages and the loss of key suppliers; product price fluctuations; inventory management risks; ability to implement our business strategies and achieve our growth objectives; acquisition and integration risks; increased operating costs; and other risks, as described in Item 1A, “Risk Factors,” and elsewhere in our Annual Report on Form 10-K for the fiscal year ended January 1, 2017.

Non-GAAP Financial Information

This release includes certain financial information, not prepared in accordance with U.S. GAAP. Because not all companies calculate non-GAAP financial information identically (or at all), the presentations herein may not be comparable to other similarly titled measures used by other companies. Further, these measures should not be considered substitutes for the information contained in the historical financial information of the Company prepared in accordance with U.S. GAAP that is set forth herein.

We present Adjusted EBITDA in order to evaluate the operating performance and efficiency of our business. Adjusted EBITDA represents EBITDA as further adjusted for items permitted under the covenants of our credit facilities. EBITDA represents our net income (loss) plus the sum of income tax (benefit), depreciation and amortization and interest expense, net of interest income. Adjusted EBITDA is further adjusted for stock-based compensation expense, related party advisory fees, (gain) loss on sale of assets and other non-cash items, other non-recurring (income) and loss. Adjusted EBITDA does not include pre-acquisition acquired Adjusted EBITDA. Adjusted EBITDA is not a measure of our liquidity or financial performance under GAAP and should not be considered as an alternative to net income, operating income or any other performance measures derived in accordance with GAAP, or as an alternative to cash flow from operating activities as a measure of our liquidity. The use of Adjusted EBITDA instead of net income has limitations as an analytical tool. Because not all companies use identical calculations, our presentation of Adjusted EBITDA may not be comparable to other similarly titled measures of other companies, limiting its usefulness as a comparative measure. Net debt is defined as long-term debt (net of issuance costs and discounts) plus capital leases, net of cash and cash-equivalents on our balance sheet. Leverage Ratio is defined as Net Debt to trailing twelve months Adjusted EBITDA. Free Cash Flow is defined as Cash Flow from Operating Activities, less capital expenditures. We define Organic Daily Sales as Organic Sales divided by the number of Selling Days in the relevant reporting period. We define Organic Sales as Net sales, including Net sales from newly-opened greenfield stores, but excluding Net sales from acquired stores until they have been under our ownership for at least four full fiscal quarters at the start of the fiscal year. Selling Days are the number of business days, excluding Saturdays, Sundays and holidays, that SiteOne branches are open during the relevant reporting period.
