CSW Industrials reported fourth quarter fiscal 2026 revenue of $309 million, beating Street estimates by more than 3% and growing 34% year-over-year — a result that pushed the company's annual revenue past $1 billion for the first time, a decade after CSW spun off as an independent public company. Adjusted EPS for the quarter reached $3.14, beating estimates by roughly a third and growing 40% from the prior year.
The headline number for HVAC contractors and distributors specifically sits inside the Contractor Solutions segment, which generated $237 million in quarterly revenue, up 43% year-over-year. CSW Chairman and CEO Joseph Armes specifically credited Aspen Manufacturing, one of the company's recent acquisitions, with growing 13.5% since being acquired in May of last year — significantly outperforming the broader market it competes in.
Why the Acquisition-Versus-Organic Split Still Matters
A meaningful share of that 43% segment growth came from acquisitions rather than organic demand — MARS Parts and Aspen Manufacturing together contributed $67 million of the quarter's growth. CSW has built its recent strategy specifically around acquiring repair- and replacement-focused HVAC/R parts businesses, a deliberate tilt away from new-unit-adjacent product categories and toward the parts and supplies that keep existing systems running.
That strategic tilt is paying off specifically because it lines up with where real demand has been concentrating. As new equipment costs more and residential replacement decisions get deferred, demand shifts toward repair — precisely the category CSW has been acquiring into. The company's own management has acknowledged the flip side of this dependency directly: any prolonged softness in core residential HVAC demand, or a slowdown in how well acquired brands integrate, remains the biggest risk to the growth story going forward.
