Higher revenues, lower profits as Littelfuse releases 2025 Q4, full-year results

Chicago, US-based electrical equipment manufacturer Littelfuse Inc released its 2025 fourth-quarter and full-year financial results on Wednesday, reporting losses despite increased revenues.

For the quarter ended December 27, 2025, the parent to the Carling Technologies marine equipment business reported consolidated net revenues of US$594m, representing a 12% year-over-year gain over revenues of $529.5m earned in the fourth quarter of 2024.

Despite a slight uptick in cost of goods sold, the firm reported a gross profit for the period of $225.7m, eclipsing the $176.8m earned in the prior Q4 by 21%.

Higher total operating expenses, including $306.8m in restructuring and impairment fees, resulted in a Q4 operating loss of $222.8m, exceeding the loss of $49.4m reported for the prior Q4.

Net loss for the quarter was $242.1m, compared to a net loss of $51.7m one year ago.

Full-year results

For the full 2025 fiscal year Littelfuse reported consolidated net revenues of $2.38bn, beating the $2.19bn earned in the prior fiscal year by 8%.

Gross profit of $906m exceeded the $787.5m earned in FY2024 for a 15% YoY gain. Increased operating expenses, again attributed to restructuring and impairment charges, resulted in a full-year operating income of $37.5m, trailing the $158.7m earned in the prior year.

Following further adjustments, the company reported a net loss for the 2025 fiscal year of $71.7m, compared against a net profit of $100.1m earned in 2024.

As the firm continues in its restructuring initiative, Littelfuse president and CEO Greg Henderson said he anticipates cost-cutting efforts and further revenue growth to bear fruit in the coming year.

“Throughout 2025, we remained disciplined in executing our strategic priorities, which is reflected in our solid full-year revenue growth and margin expansion,” said Henderson. “Across our segments, we are entering 2026 from a position of strength as we leverage our leadership in safe and efficient electrical energy transfer to accelerate growth, broaden our solutions for an expanding customer base, and drive continued operational enhancements.

“Looking ahead to the first quarter, we expect approximately 15% total revenue growth versus the prior year, supported by our strengthening backlog, deepening customer engagement, and contributions from the Basler Electric acquisition. As our end markets continue to evolve requiring higher power and energy density solutions, we remain committed to driving technology innovations to help our customers solve increasingly complex challenges.”
