ROSWELL, Ga. — (BUSINESS WIRE) —

SiteOne Landscape Supply, Inc. (the “Company” or “SiteOne”) (NYSE: SITE) announced earnings for its second

quarter ended June 28, 2026 (“Second Quarter 2026”).

“We delivered a solid second quarter

performance with 5% growth in Net sales and Adjusted EBITDA despite softer end markets,” said Doug Black, Chairman and CEO of SiteOne.

“Our teams executed well throughout the quarter, managing through the market challenges, delivering value to our customers and suppliers,

achieving operational improvements, and managing our spending to the reduced demand. Additionally, our acquisitions, led by Reinders,

continue to perform well while our pipeline of additional deals remains active. We repurchased nearly $104 million of shares during the

quarter and in July, reflecting the strength of our balance sheet, our belief in the business, and our commitment to shareholder returns.

While market conditions remain challenging, we are confident in our 2026 outlook and our ability to continue executing our strategy to

drive sustainable long-term performance and growth.”

Second Quarter 2026 Results

Net sales for the Second Quarter 2026 increased 5% to $1,530.7

million, compared to $1,461.6 million for the prior year period. Organic Daily Sales increased 1% compared to the prior year period,

driven primarily by price inflation in response to rising costs and our commercial initiatives, partially offset by softer demand in

the new residential construction and repair and upgrade end markets. Acquisitions contributed $49.2 million, or 3%, to Net sales

growth during the quarter.

Gross profit increased 6% to $564.5 million for the Second

Quarter 2026, compared to $531.4 million for the prior year period. Gross margin improved 50 basis points to 36.9%, driven primarily

by higher price realization and continued benefits from commercial initiatives, partially offset by higher freight and distribution

costs as well as deflation in certain commodity products.

Selling, general and administrative expenses (“SG&A”)

for the Second Quarter 2026 increased to $370.7 million from $349.1 million for the prior year period. SG&A as a percentage of Net

sales increased 30 basis points to 24.2% due primarily to the modest Organic Daily Sales growth and higher fuel cost during the quarter,

partially offset by our operational initiatives and continued cost control.

Net income attributable to SiteOne for the Second Quarter 2026

increased 8% to $139.3 million compared to $129.0 million for the prior year period, reflecting gross margin expansion,

partially offset by lower sales volume and higher SG&A.

Adjusted EBITDA1 for the Second Quarter 2026 increased 5%

to $237.2 million, compared to $226.7 million for the prior year period. Adjusted EBITDA margin of 15.5% was flat compared to the prior

year period.

Net debt, calculated as long-term debt (net of issuance costs and discounts)

plus finance leases, net of Cash and cash equivalents on our balance sheet as of June 28, 2026, was $555.6 million compared to $531.6

million as of June 29, 2025. Net debt to Adjusted EBITDA1 for the last twelve months was 1.3 times, which was unchanged

compared to the prior year period.

As of June 28, 2026, Cash and cash equivalents

were $87.4 million and available capacity under the ABL Facility was $443.0 million.

1. Adjusted EBITDA includes contribution from non-controlling interest of $1.3 million for the Second Quarter 2026.

Outlook

“Our end markets continue to be

challenging and we estimate new residential construction is down high-single digits with repair and upgrade also down mid-single

digits, more than offsetting modest growth in maintenance and flat new commercial construction,” Doug Black continued.

“Given the ongoing macroeconomic uncertainty, we expect these trends to continue through the full year. Pricing was up 3% in

the quarter and we expect this also to continue through the remainder of the year. With the benefit of our commercial initiatives

and price inflation, we expect Organic Daily Sales growth to be flat to up 1% for the full year. We expect to also expand our Gross

margin through continued price realization and execution of our commercial initiatives. We expect SG&A as a percentage of Net

sales to be approximately flat for the full year as our operational initiatives offset the effect of lower sales volume and the

negative effect of the extra week in December. Overall, including contributions from acquisitions, we expect to continue expanding

our Adjusted EBITDA margin in 2026.”

In fiscal year 2026, our results include an

extra week compared to the prior year period. The extra week occurs in December of our fiscal fourth quarter during a historically

slower sales period and, as a result, is expected to reduce Adjusted EBITDA for the year by approximately $4 million to $5 million.

With all these factors in mind and including

the negative effect of the 53rd week, we continue to expect Adjusted EBITDA for fiscal year 2026 to be in the range of $425

million to $455 million. Our guidance does not include any contributions from unannounced acquisitions.

Reconciliation for the forward-looking full

year 2026 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.

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 business, economic, and financial market conditions, the level of new home sales and construction

activity, geopolitical conflicts, trade disputes, inflationary pressures, capital markets volatility, and declines in consumer confidence;

severe weather and climate conditions; seasonality of our business and its impact on demand for our products; volatility in the prices

for the products we purchase and the costs required to operate our business; laws and regulations governing our operations; hazardous

materials and related materials; laws and government regulations applicable to our business that could negatively impact demand for our

products; competitive industry pressures; supply chain disruptions (including as a result of geopolitical conflicts, the imposition of

U.S. tariffs or any changes affecting tariffs resulting from the U.S. Supreme Court decision), product or labor shortages, and

the loss of key suppliers; inventory management risks; ability to implement our business strategies and achieve our growth objectives;

acquisition and integration risks, including increased competition for acquisitions; risks associated with our large labor force and our

customers’ labor force, as well as labor market disruptions; public perceptions that our products and services are not environmentally

friendly or that our practices are not sustainable; retention of key personnel; construction defect and product liability claims; impairment

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 Net income (loss) plus the sum of income tax expense (benefit), interest expense, net of interest income,

and depreciation and amortization. Adjusted EBITDA represents EBITDA as further adjusted for stock-based compensation expense, (gain)

loss on sale of assets and termination of finance leases not in the ordinary course of business, financing fees, as well as other fees

and expenses related to acquisitions, and other non-recurring (income) loss. Adjusted EBITDA includes Adjusted EBITDA attributable to

non-controlling interest. Adjusted EBITDA does not include pre-acquisition acquired Adjusted EBITDA. Adjusted EBITDA is not a measure

of our liquidity or financial performance under U.S. GAAP and should not be considered as an alternative to Net income, operating income

or any other performance measures derived in accordance with U.S. 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 finance

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. Base Business is defined as SiteOne

operations excluding acquired branches that have not been under our ownership for at least four full fiscal quarters at the start of the

fiscal year. 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 branches, but excluding Net sales from acquired branches

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.
