Watsco (WSO) Q3 2025 earnings review
Record Gross Margin Can't Offset Weaker Demand and Higher Costs
Watsco reported a challenging third quarter, with revenue declining 4% YoY to $2.07 billion as weaker unit volumes, particularly in HVAC equipment (-7%), outweighed pricing gains. The highlight was a record Q3 gross margin of 27.5% (+130 bps YoY), driven by pricing on new A2L-refrigerant products and technology-led optimization. However, this gain was entirely consumed by a 5% increase in SG&A expenses, tied to the complexities of the A2L product transition. As a result, operating income fell 6% and EPS dropped to $3.98 from $4.22. On a positive note, the company generated record Q3 operating cash flow of $355 million by successfully reducing inventory built up earlier in the year. Management commentary suggests a soft Q4, with October sales trending down 5-10%.
🐂 Bull Case
Achieving a record 27.5% gross margin in a weak demand environment demonstrates significant pricing power and the success of the company's pricing optimization technology. This suggests a higher sustainable margin floor post-transition.
The company effectively managed working capital, generating a record $355 million in Q3 operating cash flow by reducing inventory by $351 million. The balance sheet remains pristine with no debt, providing flexibility for M&A and investment.
Management stated the disruptive A2L product transition is 'substantially complete,' which should lead to a normalization of elevated SG&A costs and operational complexity in 2026.
🐻 Bear Case
Revenue has declined for three consecutive quarters, and the trend is decelerating, with management guiding to a 5-10% decline in October. Weakness in the core HVAC equipment segment (-7%) points to a challenging macro environment.
A 5% rise in SG&A on a 4% sales decline led to a 6% drop in operating income. This shows that in the near term, cost inflation and transition expenses are more than offsetting the impressive gross margin gains.
The fourth quarter faces a difficult comparison, as unit volumes in Q4 2024 were up nearly 20% due to channel stocking of older 410A products. This makes a significant sales decline highly likely.
⚖️ Verdict: 🔴
Bearish. While the structural improvement in gross margin is a significant long-term positive, it is currently overshadowed by deteriorating demand and negative operating leverage. The company is executing well operationally (cash flow, balance sheet), but the top-line weakness and its impact on profitability are the dominant factors. The outlook for Q4 suggests the near-term challenges will persist.
Key Themes
A2L Transition Drives Costs Higher Than Margin Gains
The industry-wide transition to A2L refrigerants was the quarter's defining theme, creating significant operational friction. While it enabled double-digit price increases on new products, it also drove SG&A up 5.3% ($17M) due to increased labor, logistics, and training. This cost increase completely erased the $2.7M YoY gain in gross profit, causing operating income to fall by $15.5M. This demonstrates that the costs to execute the transition were a major headwind to profitability this quarter.
Technology Platforms Prove Pricing Power
Watsco's pricing optimization platform was a key driver of the record 27.5% Q3 gross margin. Management credits these data-driven tools for enabling swift reaction to market changes and efficient administration of vendor cost changes. This structural capability allows the company to enhance profitability even when volumes are declining and is a core component of its strategy to reach a 30%+ gross margin target over the long term.
Working Capital Normalizing After Inventory Peak
After a massive inventory build in H1 2025 to support the A2L transition (peaking at $2.1B), the company began to aggressively unwind this position in Q3. Inventory was reduced by $351 million during the quarter, driving a record $355 million in operating cash flow. This demonstrates strong execution and is a crucial step to improving inventory turns and enhancing returns on invested capital. Further reductions are targeted for Q4.
Deteriorating End-Market Demand
Underlying demand appears to be worsening. The core HVAC Equipment segment saw sales decline by 7% YoY. Management characterized October sales as down 5-10%, a potential acceleration from the 4% decline in Q3. This is compounded by commentary from competitor Carrier about a sharp drop in distributor unit sales, signaling broad-based channel weakness driven by soft consumer spending and slower housing activity.
Digital Ecosystem Continues to Scale
Watsco's digital platforms remain a key competitive advantage and growth driver. E-commerce sales reached $2.5 billion for the last twelve months, representing 34% of total sales. The authenticated user base for its HVAC Pro+ mobile app grew 18% YoY to 72,000 contractors. Its OnCallAir digital sales platform is driving an annualized GMV of $1.72 billion for its customers, creating a sticky ecosystem that lowers customer attrition.
Resilient Parts Sales Not Enough to Offset Equipment Weakness
The company's sales mix shows a divergence: HVAC equipment sales fell 7%, while 'Other HVAC Products' (parts and supplies) grew 2%. While the growth in higher-margin parts is a positive for gross margin percentage, the decline in big-ticket equipment sales is too large to overcome. As confirmed on the call, the parts business is not large enough to substitute for the revenue lost from the replacement market, highlighting the company's exposure to weak consumer spending on large projects.
Other KPIs
Stable/Decelerating. A clear split emerged in performance. HVAC Equipment sales, representing 67% of the total, fell 7% YoY. In contrast, Other HVAC Products (29% of sales) grew 2% and Commercial Refrigeration (4% of sales) grew 4%. This highlights that while the repair/parts market is resilient, the larger new system replacement market remains under significant pressure.
Reversing. The company produced a record $355 million in operating cash flow, a sharp reversal from the cash use of $185 million in the first half of the year. The strong performance was driven almost entirely by a $351 million reduction in inventory. This signals a successful start to normalizing working capital after the A2L transition buildup.
Stable. The company ended the quarter with $324 million in cash, $200 million in short-term investments, and no debt. This pristine balance sheet provides significant operational and strategic flexibility, allowing for continued investment in technology and opportunistic M&A during a period of market softness.
Guidance
Decelerating. Management commentary on October trends points to a revenue decline of 5-10%. This would represent a deceleration from the 4% declines seen in Q2 and Q3. The expected weakness is driven by a combination of ongoing end-market softness and an extremely difficult year-over-year comparison, as Q4 2024 sales benefited from significant channel stocking of pre-transition equipment.
Key Questions
SG&A Cost Normalization
You expect SG&A to improve now that the A2L transition is largely complete. Can you quantify the level of transitory costs incurred in Q3 and provide a target for SG&A as a percentage of sales in a more normalized 2026 environment?
Underlying Demand Trajectory
Given the -5% to -10% revenue decline seen in October against a very tough comp, how are you thinking about the underlying end-market demand trajectory heading into 2026, separate from the comp effect? Are you seeing any signs of stabilization?
Gross Margin Sustainability
Q3 gross margin was a record 27.5%, but down sequentially from 29.3% in Q2. As the one-time OEM pricing benefits fade, what is the sustainable gross margin run-rate we should expect, and what are the key levers to reach your 30% long-term target?
Competitive Environment
With unit volumes under pressure across the industry, are you seeing any increase in competitive intensity or promotional activity from smaller distributors or OEMs that could pressure pricing in the coming quarters?
