What these concentrations mean together
updated 2026-08-09Frequency Electronics' revenue is concentrated around the U.S. government as an end customer, layered with segment- and supplier-level exposures. More than 95% of the FEI-Zyfer segment's revenues are derived from sales where the end user is the U.S. Government — a high-share, mixed-character exposure. At the consolidated level, approximately 94% of the company's sales (98% in the prior year) were made under contracts to the U.S. Government or subcontracts for U.S. Government end-use, also high-share and mixed, given the government payer base spans many individual programs and agencies rather than one counterparty. Product-line concentration adds another high-share layer: approximately 76% of consolidated revenues (73% the prior year) came from products sold by the FEI-NY segment. That segment is itself dependent on a limited number of suppliers for space-qualified parts, a medium-share, dependency-type exposure that could constrain FEI-NY's ability to fulfill the demand underlying its 76% revenue share. Separately, Northrop Grumman accounted for more than 10% of consolidated revenues in fiscal year 2025, a low-share, mixed exposure. Because the government end-market, FEI-NY segment, and space-parts supplier exposures are all high- or medium-share and interlinked, this cluster — rather than the smaller Northrop Grumman line — is what would most likely move the verdict if disrupted.
