COMFORT SYSTEMS USA INC Q3 FY2026 earnings call

• Record Backlog: End-of-quarter backlog hit a record $17.8 billion, up $8.4 billion (90%) year-over-year and $3.8 billion (27%) sequentially, driven by strong demand in technology and industrial sectors.
• Acquisition Strategy: Acquired Boys Electrical and Neopod, expected to contribute over $100 million in annual revenue. Management emphasizes a disciplined, patient acquisition approach focused on cultural fit and financial strength of counterparties.
• Leadership Transition: Bill George is retiring after 30 years; Julie Shaeff is promoted to CFO. Management expresses high confidence in the depth of the finance team and the continuity of the acquisition strategy.
• Modular Expansion: On track for over 4 million square feet of modular capacity by end of 2026, with expectations to reach approximately 6 million square feet by end of 2027. Modular accounts for 17% of YTD revenue.
• Operational Execution: Service revenue grew 13%, representing 10% of total revenue. Construction accounted for 90% of revenue. Management highlights strong labor availability as a key enabler, noting they plan labor against every dollar in backlog before accepting work.

Total revenue reached $3.8 billion, an increase of 54% year-over-year. The Electrical segment contributed significantly with 85% revenue growth, while the Mechanical segment grew by 43%. For the first nine months, same-store revenue increased by 47%, and the company expects full-year same-store revenue to remain in the mid-40% range. Gross profit totaled $934 million with a consistent gross profit percentage of 24.8%. The Mechanical segment's gross margin improved to 25.1% (from 24.3% prior year), whereas the Electrical segment's margin slipped to 24.3% (from 26.2%) due to higher equipment/material costs and discrete gains in the prior year that are not recurring.

• Full-Year Same-Store Revenue: Expected to grow in the mid-40% range for 2026.
• Next Year Revenue Growth: Estimated to grow in the mid-20% range for 2027.
• Gross Margins: Expects 2027 gross profit margins to continue in the strong ranges achieved in recent quarters.
• Tax Rate: Expects the effective tax rate to remain around 23% for the remainder of 2026 and throughout 2027.
• Capital Expenditures: Estimates full-year CapEx will be 45% of revenue, with elevated levels likely continuing into the first half of 2027 to support prefabrication and modular expansion.

• Labor Availability: The primary constraint on growth is the ability to secure sufficient craft labor; management notes that demand exceeds industry delivery capacity.
• Customer Financial Strength: Emphasis on counterparty risk, particularly regarding payment terms and financial stability of new customers in the modular space.
• Project Early Stage Risks: Significant portion of backlog is early in its lifecycle, meaning margins may fluctuate due to unknowns like weather or subcontractor performance until projects reach 40-70% completion.
• Regulatory/Political Uncertainty: While no immediate delays reported, potential data center moratoriums or regulatory changes could shift project locations or schedules.

Q: Analyst asked about the drivers behind the significant backlog increase and whether it stems from traditional data center clients or new entrants.

A: Management confirmed new customers are entering, but demand is broadly strong across all sectors. The primary constraint is labor availability rather than demand. Customers are committing earlier and for larger scopes to lock in scarce capacity, leading to record backlog levels. Repeat business from sophisticated clients remains high due to quality execution.

Q: Analyst inquired about the decision metrics for adding programmatic customers in the modular business, given current demand.

A: Management explained they prioritize existing programmatic partners with proven five-year volume commitments and financial stability. They avoid diverting resources to 'mystery' clients without similar guarantees. While building products for new Frontier Lab and colo providers, these relationships have not yet met the threshold for programmatic status due to concerns over payment timing and long-term viability compared to established partners.

Q: Analyst questioned the impact of political rhetoric and data center moratoriums on project pipelines.

A: Management reported no micro-level delays or schedule pushes from such rhetoric. However, macro-level shifts may occur as hyperscalers favor jurisdictions perceived as more business-friendly. Modular operations are less exposed as production can shift based on customer site location. No projects have been impacted at this time.

Q: Analyst asked about the magnitude of orders taken and the confidence in phasing out such large volumes.

A: Management stated they only accept work they can execute with available personnel and favorable labor timing. The company’s collaborative culture allows for a traveling workforce to fill gaps. They remain disciplined, refusing work they cannot perform at high margins, ensuring they can handle the current backlog with existing forces.

Q: Analyst sought clarity on why material/equipment mix drove down margins this quarter and if it signals a trend.

A: Management clarified that material costs were ~2% higher than H1 average, exacerbated by early-stage jobs where long pipe runs and early deliveries inflate cost-of-goods-sold ratios. This is a temporary lumpy effect, not a structural margin decline. Core profitability per hour worked continues to improve, and margins are expected to normalize as jobs mature.
