ROSWELL, Ga. — (BUSINESS WIRE) —

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

ended September 27, 2026 (“Third Quarter 2026”).

“We delivered a solid third quarter

performance with 8% growth in Adjusted EBITDA and 60 basis points of Adjusted EBITDA margin expansion despite the continued softness

in underlying market demand and a delayed fall season due to hot and dry weather in key markets,” said Doug Black, Chairman and

CEO of SiteOne. “Our teams made good progress on our commercial and operational initiatives while maintaining disciplined cost control

in the face of lower sales volume. We also completed one acquisition during the quarter and have a very active pipeline of potential deals.

While we expect market conditions to be challenging in the near term, we remain focused on the opportunities within our control to gain

market share, improve productivity, and strengthen our competitive position. These self-help opportunities combined with our acquisition

strategy enable us to drive sustained performance and growth for our shareholders this year and in the years to come.”

Third Quarter 2026 Results

Net sales for the Third Quarter 2026 increased 3% to $1,291.1 million,

compared to $1,258.2 million for the prior year period. Organic Daily Sales decreased 1% compared to the prior year period, as lower sales

volume amid continued softness in underlying market demand and a delay in fall applications due to hot and dry weather conditions more

than offset higher price inflation. Acquisitions contributed $39.7 million, or 3%, to Net sales growth during the quarter.

Gross profit

increased 5% to $458.5 million for the Third Quarter 2026, compared to $437.2 million for the prior year period. Gross margin improved

80 basis points to 35.5%, driven primarily by strong price realization, including the impact of fuel surcharges, and continued benefits

from our commercial initiatives.

Selling, general

and administrative expenses (“SG&A”) for the Third Quarter 2026 increased to $368.7 million from $357.4 million for the

prior year period. SG&A as a percentage of Net sales increased 20 basis points to 28.6% due primarily to higher fuel and healthcare

cost as well as lower sales volume, partially offset by our operational initiatives and continued cost control.

Net income attributable to SiteOne for the Third Quarter 2026 increased

8% to $63.9 million compared to $59.1 million for the prior year period, reflecting gross margin expansion, partially offset by lower

sales volume and higher SG&A.

Adjusted EBITDA for the Third Quarter 2026 increased 8% to $138.3 million,

compared to $127.5 million for the prior year period. Adjusted EBITDA margin improved 60 basis points to 10.7%.

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 September 27, 2026, was $522.6 million compared to $422.5

million as of September 28, 2025. Net debt to Adjusted EBITDA for the last twelve months was 1.2 times, compared to 1.0 times for the

prior year period.

As of September 27, 2026, Cash and cash equivalents

were $88.4 million and available capacity under the ABL Facility was $478.0 million.

Share Repurchase Increased

Authorization Announcement

Subsequent to the end of the Third Quarter 2026, SiteOne’s Board

of Directors approved a $500.0 million increase to the Company’s existing share repurchase program, authorizing approximately $538.3 million in the aggregate for share repurchases, inclusive of approximately $38.3 million that remained available under the previously

approved $400.0 million share repurchase authorization. The updated share repurchase authorization does not have an expiration

date, and the timing and amount of any share repurchases will be at the discretion of management and subject to applicable laws.

“Given our strong balance sheet, cash flow generation, and confidence

in the long-term value we can create at SiteOne, we believe the $500 million increase in our share repurchase authorization enhances our

ability to create value for shareholders,” Doug Black continued. “We remain focused on disciplined capital allocation, balancing

opportunistic share repurchases with continued investment in organic growth and acquisitions to drive long-term growth and returns.”

Outlook

“Our end markets continue to be

challenging with declines in new residential construction and repair and upgrade more than offsetting the more resilient maintenance

and new commercial construction end markets,” Doug Black continued. “Pricing was up 4% in the quarter, and we expect

this to continue through the remainder of the year. Note that our third quarter sales were affected by hot and dry weather in August

and September which delayed the fall season. We are currently achieving positive Organic Daily Sales growth of approximately 2% in

October, which we expect to yield Organic Daily Sales of flat to up 1% for the four-month period of July through October. Given the

ongoing macroeconomic uncertainty, high interest rates, and inflation, we expect end-market softness to continue through the full

year and with the negative impact of the 53rd week, we expect full-year Organic Daily Sales to be flat to down

1%.

We expect to continue expanding Gross margin

through price realization and execution of our commercial initiatives. We expect SG&A as a percentage of Net sales to be up for the

full year as our operational initiatives partially offset the effect of lower sales volume, higher fuel and healthcare cost, and the

negative effect of the extra week in December. We are managing SG&A tightly and making the necessary changes to optimize our cost

structure. Accordingly, we plan to reduce our workforce and consolidate or close branches in the fourth quarter and incur a corresponding

charge to Adjusted EBITDA of approximately $6 million to $8 million. Despite this charge and the negative effect of the 53rd

week, we expect to expand Adjusted EBITDA margin slightly in 2026.”

As a reminder, in fiscal year 2026, the

53rd week occurs in December of our fiscal fourth quarter during a historically slower sales period and, as a result, is

expected to reduce full-year Organic Daily Sales growth by approximately 80 basis points and Adjusted EBITDA by approximately $4

million to $5 million.

With all these factors in mind, we expect

Adjusted EBITDA for fiscal year 2026 to be in the range of $425 million to $440 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.

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

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.
