SiteOne Landscape Supply (SITE) Earnings: Q3 Fiscal 2026 Results

The quarter ended September 27, 2026 and SiteOne Landscape Supply published the results on October 28, 2026. Revenue and diluted EPS are shown against Q3 fiscal 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison.

• SiteOne's fiscal 2026 has 53 weeks. The extra week falls in December, in the fourth quarter, and SiteOne expects it to reduce full-year Organic Daily Sales growth by about 80 basis points.
• SiteOne's sales are significantly higher in the second and third quarters of each fiscal year. It reported net losses in Q4 fiscal 2025 and Q1 fiscal 2026.

How SiteOne Landscape Supply splits revenue in its own release, under its own labels, for Q3 fiscal 2026 against Q3 fiscal 2025. Indented lines are parts of the line above them.

• SiteOne Landscape Supply's Landscaping products revenue was $1.0 billion in Q3 fiscal 2026, up 2% from $978 million in Q3 fiscal 2025, 78% of total revenue.
• SiteOne Landscape Supply's Agronomic and other products revenue was $290 million in Q3 fiscal 2026, up 3% from $280 million in Q3 fiscal 2025, 22% of total revenue.

Segment lines are the figures writers cite most often, because they show where the growth in a quarter came from. Companies redraw their segments from time to time and restate the prior year to match, so a year-ago figure here can differ from the one printed a year ago. When that has happened, the note above says so.

From the earnings release

In its Q3 fiscal 2026 release, SiteOne Landscape Supply said:

“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.”

“we expect full-year Organic Daily Sales to be flat to down 1%.”

“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.”

“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.”

• Q3 fiscal 2026 (this page), reported Oct 28, 2026

SiteOne Landscape Supply is a wholesale distributor whose customers are mainly residential and commercial landscaping professionals. It splits net sales into two product categories: landscaping products (hardscapes, irrigation supplies, accessories, nursery goods and outdoor lighting), $1,001.2 million of the $1,291.1 million total in Q3 2026, and agronomic and other products (fertilizer, control products, ice melt and equipment), $289.9 million. (SiteOne Form 10-Q, Q3 2026, Oct 28, 2026)

Net sales rose 3%, and acquisitions supplied it: they contributed $39.7 million, or 3%. Organic Daily Sales fell 1%, as lower volume amid soft end-market demand and a fall season delayed by hot and dry weather more than offset price. SiteOne estimates price increases contributed approximately 4%. The quarter had 63 selling days, against 64 a year earlier. (SiteOne Form 10-Q, Q3 2026, Oct 28, 2026; SiteOne Q3 2026 release, Oct 28, 2026)

By category, Organic Daily Sales for agronomic products fell 1% in the quarter because of delayed fall applications, while landscaping products were flat. SiteOne said declines in new residential construction and repair and upgrade more than offset the more resilient maintenance and new commercial construction end markets. (SiteOne Form 10-Q, Q3 2026, Oct 28, 2026; SiteOne Q3 2026 release, Oct 28, 2026)

SiteOne's sales lean residential. In fiscal 2025 about 60% of net sales came from the residential construction sector, 32% from commercial and 8% from recreational and other, and about 36% came from products for the maintenance of existing properties. Canada is less than three percent of sales, and SiteOne had over 690 branches at September 27, 2026. (SiteOne Form 10-K, fiscal 2025, Feb 19, 2026; SiteOne Form 10-Q, Q3 2026, Oct 28, 2026)

Acquisitions remain part of the growth plan. In Q3 2026 SiteOne's subsidiary Devil Mountain bought Patterson Nursery Sales, a grower and wholesale distributor of nursery products in Eagle Creek, Oregon, and in March 2026 SiteOne bought Reinders, which has twelve locations across six Midwestern states. (SiteOne Form 10-Q, Q3 2026, Oct 28, 2026)

SiteOne Landscape Supply reports one EPS figure, on a GAAP basis. Diluted EPS was $1.46 in Q3 2026, against $1.31 a year earlier, on net income attributable to SiteOne of $63.9 million, up 8%. Its main non-GAAP measure is Adjusted EBITDA, $138.3 million, which adds back stock-based compensation ($5.6 million), gains or losses on asset sales and acquisition-related costs. (SiteOne Q3 2026 release, Oct 28, 2026)

Gross margin carried the quarter: it rose 80 basis points to 35.5% on price realization, including fuel surcharges, while SG&A rose to 28.6% of net sales on higher fuel and healthcare costs. A higher tax rate held EPS back. The effective tax rate was 26.0%, against 20.4% a year earlier, mainly because of smaller excess tax benefits from stock-based compensation. (SiteOne Q3 2026 release, Oct 28, 2026; SiteOne Form 10-Q, Q3 2026, Oct 28, 2026)

Diluted weighted average shares fell to 43,817,122 from 45,035,242. SiteOne repurchased $62.2 million of shares in the quarter and 1,597,891 shares for about $175.9 million over the first nine months, and after the quarter its board added $500.0 million to the repurchase authorization, bringing it to about $538.3 million. (SiteOne Q3 2026 release, Oct 28, 2026; SiteOne Form 10-Q, Q3 2026, Oct 28, 2026)

Diluted EPS divides net income by the weighted average number of shares outstanding in the quarter, plus the shares that options and other equity awards could add. Buybacks shrink that count and lift EPS for the same profit; share issuance and stock awards enlarge it.

SiteOne Landscape Supply gives a full-year outlook in its release. For fiscal 2026 it expects Adjusted EBITDA of $425 million to $440 million and full-year Organic Daily Sales of flat to down 1%. The outlook includes a fourth-quarter charge of about $6 million to $8 million to reduce the workforce and consolidate or close branches. (SiteOne Q3 2026 release, Oct 28, 2026)

SiteOne said pricing was up 4% in the quarter and Organic Daily Sales were growing about 2% in October. It expects the 53rd week to reduce Adjusted EBITDA by about $4 million to $5 million, and its guidance excludes unannounced acquisitions. (SiteOne Q3 2026 release, Oct 28, 2026)

A consensus figure is the average of the models published by the analysts who cover SiteOne Landscape Supply, collected by a data provider and revised up to the day of the report. A quarter that lands above it says how expectations were set as much as how the business did, and the share price on the day also reflects the guidance and the lines no consensus covers.

The consensus figures on this page are Yahoo Finance's, as pulled on the date shown. Each comes with the number of analysts behind it; the smaller that number, the more one revised estimate can move the average.

The figures below are the ones SiteOne Landscape Supply's own release and filings put weight on for Q3 fiscal 2026, with the latest reported value for each.

What the quarter means for a holding is a separate question from what it reported. The case for and against owning SITE is on is SITE a buy or a sell?, what analysts expect next is on the SITE forecast, and what the company does is on the SiteOne Landscape Supply (SITE) stock page.

Every number on this page can be traced to a document SiteOne Landscape Supply published. Checking one takes a couple of minutes, and it is worth doing before you quote a figure anywhere.

• The results release is the document linked in the source line above. Companies publish it on their investor relations site at the moment results go out, and it carries the headline tables: revenue, operating income, net income and EPS for the quarter and the year-ago quarter.
• The same release is filed with the SEC as Exhibit 99.1 to a Form 8-K under Item 2.02, usually on the day of the report. The SEC copy does not change after the fact, which makes it the safer thing to link when you cite a number.
• The quarterly report (Form 10-Q) follows within a few weeks and carries the full financial statements, the segment note and management's discussion of what changed. The fourth quarter is covered by the annual report (Form 10-K) instead.
• Restated comparisons are flagged in the notes on this page. When a company redraws its segments or changes how it adjusts EPS, it restates the year-ago column, so the year-ago figure in a new release can differ from the one printed a year ago. This page always uses the comparison in the newer release, because that is the like-for-like one.
