Watsco (WSO) Bets $500M On Plumbing’s Next Frontier
Watsco (WSO) acquired The Granite Group, a plumbing and HVAC distributor, for $500M. This is Watsco's second acquisition in 2026, following Jackson Supply. The Granite Group has $500M in annual sales and 82 locations. Watsco's Q2 revenue rose 2% to $2.1B, but gross profit fell 4% due to margin compression. The company has no debt and raised its dividend 10% in April.
How this was made

The 30-second read
Why it matters
The acquisition aligns with Watsco's long‑term playbook of adding scale without leveraging balance sheet, but recent earnings show margin pressure that could temper investor enthusiasm.
Market read
The deal is a material M&A event for a mid‑cap distributor, likely to influence sector sentiment and Watsco's stock price.
What to watch
Integration risk and potential cannibalization of existing Watsco customers could delay expected synergies.
Background
