Littelfuse Is Riding the Data Center Power Shift—and Design Wins Are Exploding!

Entering 2026, Littelfuse believes it has strong momentum in its backlog, and it sees meaningful growth opportunity across grid and utility infrastructure, data centers, and a potential industrial recovery. On profitability, Littelfuse reported an adjusted EBITDA margin of approximately 20.5% in the fourth quarter, with full-year 2025 adjusted EBITDA margin of 20.9%. Management framed these results as evidence of sustained operational discipline and said it expects margin expansion to continue through 2026. The company noted that this trajectory is already reflected in its first-quarter outlook, including expectations for EPS growth, but it emphasized that it will avoid longer-term forecasts ahead of the May Investor Day. In assessing recent performance and strategic direction, Littelfuse delivered a 12% year-over-year revenue increase in fiscal Q4, with stronger growth in areas such as data centers, grid and utility infrastructure, and renewables.
