Frequency Electronics Inc (NASDAQ: FEIM) is a defense and aerospace electronics company that designs, develops, and manufactures precision time and frequency generation systems for satellite payloads, military platforms, and secure communications infrastructure. Revenue comes primarily from long-term government and defense contracts, recognized using the cost-to-cost percentage-of-completion method. Founded in 1961 as a research and development firm in Mitchel Field, New York, FEIM operates through three segments: FEI-NY, which produces master timing systems and frequency generation products for satellite payloads and DOD applications; FEI-Elcom, which makes RF microwave modules and subsystems up to 60 GHz for electronic warfare, SATCOM, and signal intelligence markets; and FEI-Zyfer, which manufactures GPS-based precision navigation, timing, and anti-spoofing products for terrestrial secure communications. During fiscal year 2024, Lockheed Martin, Northrop Grumman, the Office of Naval Research, and BAE Systems each accounted for more than 10% of consolidated revenues, creating material customer concentration risk. As of April 30, 2025, the company held $5 million in U.S. federal net operating losses.

Revenue model

Long-term defense and commercial contracts recognized over time using the cost-to-cost method, where revenue is recorded proportionally as costs are incurred relative to total estimated contract costs. Revenue streams span satellite payload timing systems, RF microwave subsystems, and GPS-based positioning and timing products sold primarily to U.S. Government prime contractors and directly to government agencies.

Products and services

Precision quartz and rubidium master timing systems for satellite payloads; frequency generation and synchronization products for ground-based and mobile military platforms; RF microwave modules and subsystems up to 60 GHz including fast-switching synthesizers, up-down converters, receivers, tuners, ceramic resonance oscillators, and dielectric resonance oscillators (FEI-Elcom); GPS-based precision navigation, timing, and frequency products with anti-spoofing capability (FEI-Zyfer); low acceleration-sensitive oscillator technology patented for shock and vibration environments. Current patents run through 2026 per the FY2025 10-K filing.

Customers and end markets

Primary customers are U.S. defense prime contractors and government agencies. Lockheed Martin, Northrop Grumman, Office of Naval Research, and BAE Systems each exceeded 10% of consolidated revenues in fiscal year 2024. End markets include commercial and government satellite payloads, electronic warfare systems, SATCOM communications, SIGINT and COMINT collection, threat simulation, U.S. military mobile platforms, and terrestrial secure command, control, and communications systems.

Value-chain role

Vertically integrated designer, developer, and manufacturer of specialized electronic subsystems and components positioned as a Tier 2 or Tier 3 supplier to defense prime contractors. The company conducts proprietary internal R&D, holds patents on core oscillator technologies, and builds products to DOD standards, supplying timing and frequency subsystems that are embedded into larger military and satellite systems.

Geographic exposure

Principal operations headquartered at Mitchel Field, New York. Revenue is concentrated in U.S. Government and domestic defense programs. The filing references a prior strategic investment in Morion, Inc., described as a Russian crystal manufacturer, though no material current international revenue geography is disclosed in the excerpts.
