Wesco Q1 Smashes Expectations; Data Center Surge Powers Record Sales and Raised Outlook

What happened

Wesco International reported a record first quarter with net sales of $6.1 billion, up 14% year-over-year, driven by a massive 70% surge in data center sales to $1.4 billion. Organic sales grew 12%, backlog hit a record up 22% YOY, and adjusted EBITDA margin expanded 60 basis points to 6.4%. Adjusted diluted EPS jumped 52.5% to $3.37, and free cash flow of $213 million represented 128% of adjusted net income. Management raised full-year 2026 guidance, citing exceptional momentum and accelerating business conditions across all segments. The results confirm that Wesco's strategic positioning in AI-driven data centers and secular electrification trends is translating into strong operational and financial outperformance.

Implication

The Q1 beat and raised outlook reinforce Wesco's position as a primary beneficiary of secular data center and electrification tailwinds. With record backlog, strong cash generation, and expanding margins, the company is demonstrating operating leverage. Investors should monitor backlog conversion and power equipment supply, but the near-term risk/reward remains attractive. The stock likely re-rates higher as visibility improves.

Thesis delta

No fundamental shift; the existing BUY thesis is strongly supported. The rapid acceleration in data center sales and raised guidance increase confidence in the duration and magnitude of the growth cycle. The key watch items (backlog conversion, lead times) remain relevant but are trending favorably.
