Littelfuse Stock Earnings Reports

Littelfuse reported a strong start to 2026 with Q1 net sales of $657 million, up 19% year over year and 9% organically. Adjusted EBITDA margin expanded to 22.9% and adjusted diluted EPS was $3.31 (up 51% YoY). Growth was broad-based: data centers and grid/utility infrastructure delivered strong double-digit growth, diversified industrials and passives were robust, transportation grew high single digits on content expansion and share gains, and commercial vehicles expanded mid single digits. The Basler acquisition (closed December) contributed meaningfully—~6% of sales growth—and outperformed expectations in its first full quarter with strong design wins that provide longer-term visibility. Book-to-bill finished well above 1.0 and bookings were up >20% YoY. Operational excellence and a new go-to-market sales realignment are driving margin expansion and design-win momentum. Q2 guidance: net sales $690M–$710M (~14% growth, 8% organic, 6% Basler contribution) and adjusted EPS $3.65–$3.85. Cash flow was strong (operating cash flow $80M, free cash flow $66M), net leverage ~1.0x, and the company returned $90M via dividends. Management will provide greater strategic and financial detail at an Investor Day on May 14. Key investor takeaways: accelerating high-power/grid exposure via Basler, continued data center-driven demand across product lines, improving profitability through operational initiatives, disciplined M&A optionality supported by a healthy balance sheet, and a mid-term flow-through target of ~30%–35%.
