Data Center Boom Drives Record Sales and Backlog; Wesco Raises 2026 Outlook

What happened

Wesco International posted record Q2 2026 sales of $6.7 billion, up 13% organically, fueled by a 45% surge in data center revenue to $1.5 billion and a record backlog up 60% year-over-year. Profitability improved nicely with adjusted EBITDA margin expanding 60 basis points to 7.3%, driving a 35% jump in adjusted diluted EPS to a record $4.57. Despite the explosive top- and bottom-line growth, free cash flow was a modest $32 million, reflecting heavy working-capital investment to support the growth. Management raised its full-year 2026 outlook, signaling confidence that momentum will continue into the second half. The results powerfully validate the DeepValue BUY thesis centered on Wesco’s leadership in data center distribution, though cash conversion warrants closer scrutiny.

Implication

The 45% jump in data center sales and 60% backlog surge directly reinforce Wesco’s position as a prime beneficiary of AI-driven infrastructure buildout, justifying the BUY verdict. Raised full-year guidance signals management expects continued outperformance, while margin expansion demonstrates pricing power and operating leverage. However, the quarter’s $32 million in free cash flow is disappointing relative to earnings, indicating heavy reinvestment and potentially constraining buybacks. Investors should monitor whether cash conversion improves as growth normalizes; for now, the thesis remains intact with elevated conviction, but valuation upside may hinge on generating stronger free cash flow to support shareholder returns.

Thesis delta

The Q2’26 results dramatically accelerate the core thesis: data center sales soared 45% and backlog swelled 60%, far exceeding prior assumptions. This validates and strengthens the BUY case, though the weak free cash flow of $32 million adds a new focus on cash conversion; the judgment remains BUY but now carries a heightened emphasis on free cash flow generation.
