About Bel Fuse Inc.
About Bel Fuse Inc.
Bel Fuse received $732.9 million in new orders during 2025—a 75.8% increase from 2024—with Power Solutions & Protection, Connectivity Solutions, and Magnetic Solutions representing 53%, 34%, and 13% of net sales, respectively. The company employed approximately 4,964 associates across 15 countries at December 31, 2025, with 32% in North America. The November 2024 acquisition of Enercon Technologies—a customized power conversion and networking supplier to aerospace and defense—for $325.6 million expanded the company's backlog to $452.2 million by January 31, 2026.
Bel Fuse sells components to OEMs, defense primes, and industrial customers through strategic account managers, independent sales representatives, and authorized distributors. No single customer exceeded 10% of 2025 consolidated net sales, reflecting a diverse end-market mix across defense, commercial aerospace, networking, transportation, and eMobility. Within the Enercon subsidiary, approximately 93% of fiscal 2025 revenue was derived from defense industry customers across air, land, and sea applications for U.S. and Israeli prime contractors—an exposure subject to annual government appropriations cycles from both governments. Input costs include Gold, Silver, and Copper, which the filing flags as having increased supplier pricing through recent commodity cycles.
Show full overview
Bel Fuse's PRC manufacturing concentration is the most geographically specific structural risk in the filing. At December 31, 2025, 42% of the company's associates, 56% of owned or leased manufacturing facilities by square footage, and the majority of Magnetic Solutions production capacity were located in China. The 10-K explicitly flags potential trade restrictions placed on PRC suppliers by the U.S. government as a risk, alongside seasonal labor disruptions tied to the Lunar New Year holiday that have historically made the first fiscal quarter the lowest-revenue quarter of the year.
