Littelfuse, Inc. reported a total revenue of $2.39 billion for the fiscal year ending December 27, 2025, marking an increase of 8.9% from $2.19 billion in the previous year. The growth was attributed to higher sales volumes in the Electronics and Industrial segments, as well as contributions from the recent acquisition of Dortmund Fab, which added approximately $49 million in sales. However, the company experienced a net loss of $71.7 million, or $2.89 per diluted share, compared to a net income of $100.2 million, or $4.00 per diluted share, in 2024. This significant shift was primarily due to a $301.2 million non-cash goodwill impairment charge related to the Electronics-Semiconductor reporting unit.
In terms of operational performance, Littelfuse's Electronics segment generated $1.35 billion in sales, up from $1.19 billion in 2024, while the Transportation segment saw a slight increase to $676.4 million from $672.4 million. The Industrial segment also reported growth, with sales rising to $364.4 million from $331.6 million. The company’s total operating income fell sharply to $37.5 million from $158.8 million in the prior year, reflecting the impact of the impairment charges and increased operating expenses, which rose to $868.5 million from $628.8 million.
Strategically, Littelfuse made several acquisitions to enhance its market position. The acquisition of Basler Electric on December 11, 2025, for $350.3 million, is expected to strengthen its offerings in electrical control and protection solutions for industrial markets. Additionally, the Dortmund Fab acquisition, completed on December 31, 2024, for approximately €94 million, aims to bolster Littelfuse's semiconductor capabilities. These acquisitions align with the company's focus on high-growth markets, including energy storage and grid infrastructure.
The company reported a backlog of unfilled orders amounting to approximately $1.07 billion as of December 27, 2025, a significant increase from $664.9 million the previous year, indicating strong demand across its segments. Littelfuse's workforce comprised around 17,000 employees globally, with a strategic emphasis on enhancing operational excellence and customer engagement through a restructured sales approach. The company anticipates continued growth driven by increasing demand for high-power solutions and plans to unveil a long-term strategy at an upcoming investor day.
Looking ahead, Littelfuse remains cautiously optimistic about its growth trajectory, despite the challenges posed by market conditions and the recent impairment charges. The company is focused on leveraging its acquisitions and expanding its product portfolio to meet evolving customer needs in a rapidly changing technological landscape.
