Watsco (WSO) Q2 2025: Gross Margin Hits 29% as A2L Transition Drives Pricing Power
Watsco’s Q2 revealed the full impact of the A2L refrigerant transition, with gross margin surging to a record 29% despite a 4% sales decline as pricing and technology offset volume headwinds. The company’s operational focus shifted to inventory management and cost discipline as the disruptive regulatory cycle nears completion. With technology-driven margin gains, a robust balance sheet, and new national account initiatives, Watsco is positioning for normalized growth and efficiency in 2026 as the industry digests a noisy year.
Summary
- Margin Expansion Amid Disruption: Technology and OEM pricing actions delivered record gross margins despite lower volumes.
- Inventory and SG&A in Focus: Elevated inventory and transition costs weighed on efficiency, but normalization is expected as legacy SKUs clear.
- Strategic Technology Bets: Investments in digital platforms and national account solutions set the stage for future share gains and higher-margin mix.
Performance Analysis
Watsco’s Q2 performance was defined by the industry-wide A2L refrigerant transition, which affected over half of historical product sales and led to a 4% revenue decline. Double-digit price increases on new equipment, driven by OEM (original equipment manufacturer) inflation and technology-enabled pricing, more than compensated for lower unit volumes, driving gross margin to a record 29%. The company’s pricing technology platform, PriceFX, and digital selling tools contributed to this outperformance.
However, SG&A rose 6% as Watsco absorbed extra costs from the transition and expanded its branch network through acquisitions, with core SG&A up about 4.5%. Inventory peaked at $2 billion as the company carried both legacy and new products to support customers, but management indicated a reduction to $1.8 billion early in Q3. International (Mexico) sales, though a small revenue contributor, weighed on margin but showed improvement in late Q2 and July.
- Product Transition Disruption: The A2L regulatory shift pressured volumes but enabled price realization and margin gains.
- Digital Channel Growth: E-commerce reached $2.5 billion, accounting for 34% of sales, with OnCall Air platform volume up 19% to $1.6 billion.
- Inventory Overhang: Dual stocking of old and new SKUs inflated working capital needs but is expected to unwind by year-end.
While top-line growth was subdued, Watsco’s ability to expand margin and maintain a debt-free balance sheet underlines its resilience and operational flexibility in a volatile regulatory environment.
Executive Commentary
"2025 marks a year of significant product transition to next generation equipment containing A2L refrigerants. The transition affects roughly 55% of our historical product sales... Regulatory changes have historically been good for our business and good for our customers. We expect that transition to be no different than has happened in the past."
Albert Namit, Chairman and CEO
"Our performance yielded an increase in EBIT and expanded EBIT margins despite lower sales. Our results benefited from OEM pricing actions. Our pricing technology platform, called PriceFX, also contributed. Gross margins remain a focus. There is much potential to improve over time."
Barry Logan, Chief Financial Officer
Strategic Positioning
1. Margin-Driven Playbook
Watsco’s margin expansion was a direct result of its pricing technology, OEM actions, and mix management. The PriceFX platform and digital sales tools allowed the company to capture price inflation and optimize customer-level pricing, with management citing 200 basis points of gross margin improvement over three years from these initiatives. The company’s push to grow the higher-margin parts and supplies segment (now 30% of sales) is expected to further enhance profitability as the mix shifts away from lower-margin equipment.
2. Technology and Digital Channel Scale
Digital transformation remains a core differentiator. E-commerce now accounts for over a third of total revenue, and the OnCall Air platform enables contractors to sell higher-efficiency systems at a much higher rate. The company’s mobile apps reached 70,000 users, up 17%, and internal and external AI platforms are being leveraged for productivity, customer experience, and data-driven growth strategies.
3. National Account Platform Buildout
Watsco is developing a unified sales platform (“Watsco One”) to address large, multi-location institutional customers, a market segment increasingly shaped by private equity consolidation and home warranty companies. This platform will aggregate inventory, pricing, and support systems, aiming to capture incremental share and drive higher parts and supplies sales to these accounts—potentially mitigating margin pressure from bulk equipment sales.
4. Inventory and Working Capital Discipline
Inventory management is a renewed operational priority. The dual stocking of old and new refrigerant SKUs led to a $2 billion inventory peak, but management is targeting a return to pre-COVID inventory turns (goal of 5x) as the transition completes. The company is actively working down legacy stock and expects normalization by year-end, which should relieve working capital and improve efficiency metrics.
5. M&A Optionality
With a debt-free balance sheet and strong cash position, Watsco is positioned to pursue accretive M&A as market softness may prompt independent distributors to consider strategic options. Management hinted at one sizable opportunity under evaluation, underscoring the company’s readiness to capitalize on industry consolidation.
Key Considerations
Watsco’s Q2 was shaped by external regulatory disruption, but the company’s technology investments and scale delivered margin resilience and set the stage for future growth. As the A2L transition winds down, operational normalization and strategic initiatives will determine the trajectory into 2026.
Key Considerations:
- Margin Sustainability Post-Transition: Record gross margin benefited from temporary OEM price actions; normalization to 27%+ is expected in the second half.
- Working Capital Release: Inventory reduction is underway, with $200 million already worked down in Q3, supporting future cash flow.
- Parts and Supplies Upside: Expansion of this higher-margin segment is a central lever for future profit growth and margin stability.
- National Account Penetration: Success of Watsco One could unlock new revenue streams and strengthen competitive differentiation.
- SG&A Efficiency: Transition-driven cost inflation is expected to abate, but cost discipline remains a focus as operations normalize.
Risks
Watsco faces a mix of macro and industry-specific risks, including continued demand softness in residential new construction, unpredictable weather patterns, and tariff-driven cost inflation on parts and supplies. Execution risk remains around inventory normalization, while national account strategies could pressure margins if not offset by mix gains. The regulatory cycle’s aftershocks and ongoing market “noise” may create further volatility in volumes and operating efficiency.
Forward Outlook
For Q3 2025, Watsco expects:
- Continued improvement in inventory turns as legacy SKUs clear
- Gross margin to moderate from Q2 peak, but remain above historical floor (27%+)
For full-year 2025, management maintained a focus on:
- Margin outperformance relative to pre-transition benchmarks
- Inventory and SG&A normalization as the A2L transition completes
Management highlighted several factors that will shape H2 performance:
- Weather and consumer demand remain unpredictable, especially in northern markets
- Technology and mix initiatives are expected to drive incremental margin and share gains
Takeaways
Watsco’s Q2 demonstrated the company’s ability to leverage technology and pricing discipline to offset industry disruption, with a clear path to post-transition normalization and renewed growth ambitions.
- Margin Engine: Technology-enabled price optimization and mix shift to higher-margin parts and supplies will be critical to sustaining margin gains as OEM price tailwinds fade.
- Operational Reset: Successful inventory drawdown and cost normalization are essential for unlocking working capital and restoring efficiency.
- Strategic Growth Levers: The rollout of the Watsco One platform and continued digital investments position the company for share gains and higher customer lifetime value in a consolidating industry.
Conclusion
Watsco’s Q2 was a margin-driven quarter, with technology and pricing acumen cushioning regulatory and demand shocks. As the A2L transition cycle nears completion, the company’s operational focus shifts to efficiency and growth, with digital and national account strategies poised to drive future upside.
Industry Read-Through
Watsco’s results and commentary provide a clear read-through for the broader HVAC distribution and building products space: Regulatory-driven product cycles can create near-term disruption but also enable margin expansion for scale players with pricing power and digital capabilities. The shift toward technology-enabled selling, e-commerce, and AI-driven operations is accelerating, creating a widening gap between digitally advanced distributors and traditional peers. Tariff and commodity cost volatility, as well as working capital discipline, are key themes for the sector as inventories and cost structures normalize post-regulatory transition. Distributors with balance sheet strength and M&A readiness are best positioned to capitalize on industry consolidation and evolving customer needs.
