Watsco is North America's largest HVAC distributor with 11-12% market share, more than twice its next competitor, and focuses only on HVAC.
The 2009 Carrier joint venture nearly doubled Watsco's revenue and now supplies 65% of its purchases.
Repair-and-replacement demand drives most Watsco revenue and has helped deliver 20% annualized shareholder returns over 30 years.
Watsco turned HVAC distribution into a 20% compounder
Watsco is the pure-play consolidator of North American HVAC distribution, a $64bn market of more than 2,000 distributors serving demand that cannot be deferred. Its 2009 Carrier joint venture brought scale, better purchasing terms and a partner that folds acquisitions into the venture. Decentralised operating companies, exclusive regional manufacturer relationships and restricted stock that vests at 62 keep the compounding running, and cash conversion above 100% funds both the dividend and the deals.
Takeaways
Watsco has compounded at 20% for decades. Revenue went from about $64m in 1989 to roughly $7.5bn, and market capitalisation from $22m to $20bn. The 20% annualised shareholder return held across five, ten, twenty and thirty-year periods.
Replacement demand, not construction, drives sales. A failed air conditioner or furnace cannot be deferred, so repair and replacement supplies most revenue. Commercial and residential look similar, both resting on exclusive regional agreements between a manufacturer and a distributor.
The Carrier venture reshaped Watsco's economics. The 2009 equity-financed joint venture nearly doubled revenue, adding about $1bn. Carrier's margins were then roughly 2%, a third of Watsco's, and have since grown sixfold. Carrier supplies 65% of purchases.
A fragmented market rewards the pure play. North American HVAC distribution is worth about $64bn and served by more than 2,000 distributors. Watsco holds 11 to 12% share, more than twice its nearest competitor, and unlike them stays out of plumbing and industrial markets.
Margins and cash fund a compounding dividend. Gross margin is just under 27% against management's 30% ambition, operating margin just below 11%, and cash conversion above 100%. Two-thirds of free cash flow is paid out, with dividends compounding over 20% for 35 years.
Deals stay disciplined and culturally aligned. Watsco has made more than 70 acquisitions, nine since 2017 adding $1.2bn of revenue, funded with minimal debt on a never bet the ranch rule. Its 2017 stake in Russell Sigler has grown operating profit over 400%.
Digital tools and restricted stock raise retention. E-commerce has grown from about a quarter of sales in 2017 to near 35%, with lower attrition and 20 to 25% more line items ordered online. Restricted stock cliff-vests at 62, with only 8% forfeited in 25 years.
