Revenue by Segment
Breaks down Bel Fuse’s sales across its business segments, showing which product areas drive growth, where demand is strongest, and how diversified the company’s revenue base is.Bel Fuse’s revenue mix is undergoing a major strategic reset: the formerly dominant Power Solutions & Protection and Connectivity businesses have been reorganized into Aerospace, Defense & Rugged Solutions and Industrial Technology & Data Solutions, making the 2026 zeros a reporting change rather than a collapse. Growth is now concentrated in defense, data solutions and HPC-related demand, with both new segments expanding at double-digit rates. Six consecutive quarters of book-to-bill above one supports continued momentum, although working-capital needs, supply constraints and delayed European defense monetization remain key execution risks.
