Why did WSO stock fall?

Watsco stock fell 12.9% on July 29, 2026, after the company reported second-quarter earnings that missed analyst expectations on both profit and revenue, while gross margins contracted sharply due to pricing normalization and A2L refrigerant regulation impacts.

  • EPS and revenue miss: Watsco reported earnings per share of $4.00, missing the consensus estimate of approximately $4.39–$4.41, and revenue of $2.1 billion, a 2.1% year-over-year increase that fell short of expectations.
  • Gross margin compression: Gross margin declined 180 basis points to 27.5% from 29.3% in the prior-year quarter, driven by normalization of pricing power and industry shifts related to new A2L refrigerant regulations.
  • Operating margin deterioration: Operating margin fell to 11.3% from 13.2% year-over-year, resulting in an approximate 12% drop in total operating income.
Note: The published narrative cites a 15.40% intraday decline and references an 8-K filing as a trigger, but the confirmed session move is 12.9% (close-to-close); the primary catalyst was the earnings miss and margin compression, not an administrative 8-K filing.
