3 min read

Record first-quarter sales of $6.1 billion were driven by a 70% year-over-year surge in data center demand, which now represents 24% of total company revenue.
Organic sales growth outpaced normal seasonality, reflecting broad-based strength across CSS and EES segments and improving trends in UBS.
Backlog reached a record level, up 22% versus the prior year, providing high visibility into secular growth trends and the effectiveness of cross-selling initiatives.
Adjusted EBITDA margin expanded 60 basis points to 6.4% due to gross margin expansion and strong operating leverage on double-digit sales growth.
While the industrial segment declined low single digits in Q1 due to project timing, management remains optimistic about a long-term ‘industrial super cycle’ driven by AI infrastructure, power generation needs, and reshoring trends.
The CSS segment achieved a 9% EBITDA margin, benefiting from stable gross margins and significant operating cost leverage despite large project mix.

Full-year 2026 organic sales growth guidance was raised to 5% to 8%, with CSS outlook increased to low double-digit growth based on data center visibility.
Data center sales are now projected to grow 20%+ for the full year, though management notes that quarterly growth rates will be calibrated by project timing and customer labor constraints.
Second-quarter EBITDA margins are expected to be approximately flat year over year, impacted by a 25-30 basis point headwind from higher incentive compensation.
The company anticipates generating $500 to $800 million in free cash flow, with approximately 70% typically occurring in the second half of the year.
Interest expense assumptions remain unchanged, factoring in a ‘higher-for-longer’ rate environment with no anticipated rate cuts in 2026.

A successful $1.5 billion bond refinancing is expected to generate more than $20 million in annualized interest expense savings and improve the debt maturity profile.
The company reached a milestone in its digital transformation, fully deploying one end-to-end P&L operation within its CSS segment on its new digital platform at the end of Q1.
Supply chain lead times remain extended for critical categories like switchgear (40-60 weeks), though management believes they are navigating these shortages effectively.
Macroeconomic risks, including Middle East volatility and tariffs, are currently viewed as manageable with less than 1% of sales generated in the affected region, the majority of which are related to the CSS business.
