Watsco 2025-26: A2L Pricing +Double-Digit, 12 Acquisitions, Dividend +10%

FY25 revenue $7.24B (-5%); op income $693M (-11%); NI $497M (-7%); EPS $12.25 (-8%). Q4: double-digit pricing gains on new A2L products; gross margin +40bp to 27.1%. SG&A -2% on operating efficiency. 12 business acquisitions FY25. Annual dividend boosted +10%. Ecommerce 35% of sales (60%+ in some US markets). OnCallAir digital selling platform GMV +20% to $1.8B. Mobile app user expansion. Commercial product down high single digits; international weak (Canada better Q4; Latin America similar). FY26: margins gradually improve as transition matures; focus on inventory turns + cash flow + tech investment + AI.

Key takeaways

  • A2L refrigerant transition driving pricing — double-digit pricing gains on new A2L products. A2L (low-GWP refrigerants A2L class) is the structural EPA-mandated refrigerant transition for residential + commercial HVAC. Watsco's A2L pricing is delivering double-digit gains in Q4 — meaningful margin expansion lever as transition continues through 2026-2028.
  • 12 business acquisitions FY25 — disciplined consolidation strategy. Watsco continues consolidating the fragmented HVAC distribution market via tuck-in M&A. 12 deals in 2025 demonstrates active deployment + execution. Multi-year strategy to be the dominant national HVAC distribution platform.
  • Dividend boosted +10%; capital return culture. Annual dividend +10% reflects mgmt confidence in cash flow + business model. Long-term dividend track record. Combined with selective M&A + technology investment + buybacks (selective).
  • Ecommerce 35% of sales / 60%+ in some US markets. Digital transformation thesis playing out. OnCallAir digital selling platform GMV +20% to $1.8B. Mobile app expansion. Watsco is leveraging tech for B2B + contractor adoption.
  • FY25 unit volumes declined; FY26 outlook says no clear call yet but more conventional starting place. Industry sell-through 2025 was correction year; 2026 likely more normal volume environment.

FY26 outlook (per Q4 2025 call, 2026-02-17)

FY26 frameworkDetail
MarginsGradually improve as transition matures
Inventory turnsFocus on improvement
Cash flowGenerate incremental
Innovation + techContinue investment
Industry sell-through volumesNo clear call yet but more conventional starting place after 2025 correction
A2L pricingContinued gains expected
Ecommerce + OnCallAirContinued growth

Key risks

Industry sell-through volumes uncertainty. Q4 mgmt: "no specific clear call on industry sell through volumes for 2026 yet." Historical correction in 2025 + macro dynamics + housing sensitivity create demand uncertainty.

Regulatory changes (past disruptions, potential future). A2L transition has been disruptive; future regulatory changes (refrigerant + efficiency + safety) could create unforeseen impacts.

Geopolitical issues. Could affect international + certain domestic markets. Q4 mgmt called out.

Commodity price volatility (copper). Q4 mgmt: copper price volatility could impact margin if not managed properly. Multi-quarter hedging + pass-through.

Pricing dynamics. A2L pricing gains driven by transition; sustainability depends on market conditions + competitive intensity.

Acquisition integration. 12 deals FY25 + ongoing M&A pipeline. Integration capacity + synergy delivery matter.

Customer concentration. Top contractor customers + national accounts drive significant revenue.

Macro / housing demand. HVAC demand correlated to housing + repair-and-replace cycle + consumer spending.

Commercial product weakness. Down high single digits Q4. Continues into FY26?

International market dynamics. Canada + Latin America weak FY25. Multi-jurisdiction navigation.

Technology execution. OnCallAir + AI + mobile app investments require continued execution.

Talent retention. Distribution network + technology talent retention.

Bottom line

Watsco FY25 is the cyclical correction + A2L transition pricing + 12-acquisition consolidation year: revenue -5% to $7.24B; op income -11%; EPS $12.25 (-8%); FCF $536M (-28%). Q4 highlights: A2L pricing +double-digit; gross margin +40bp to 27.1%; SG&A -2%; ecommerce 35% of sales; OnCallAir GMV +20% to $1.8B; 12 acquisitions FY25; dividend boosted +10%.

FY26 framework: margins gradually improve as A2L transition matures; focus on inventory turns + cash flow + tech investment + AI. Industry sell-through "no clear call yet but more conventional starting place after 2025 correction." Continued M&A + tech investment + dividend culture.

The risks are real — industry sell-through volume uncertainty, regulatory changes, geopolitical issues, copper price volatility, A2L pricing sustainability, acquisition integration, customer concentration, macro / housing demand, commercial product weakness, international dynamics, technology execution, talent retention.

But the structural thesis (largest US HVAC/R distributor + A2L transition pricing + technology platform + 12-acquisition pace + dividend culture + ecommerce growth + multi-market consolidation) is intact and FY25 print confirms.

Quality HVAC/R distribution compounder mid-cyclical-correction + A2L-transition cycle. The A2L pricing momentum + technology platform expansion + tuck-in M&A pace + dividend culture + multi-year housing recovery thesis creates a multi-year compounding setup. Investors get exposure to HVAC/R distribution consolidation + A2L transition + ecommerce growth + dividend culture. The conservative FY26 framework + Q1 starting point + technology investment + M&A pipeline provides multiple paths to outperformance over multi-year horizon.
