What Epsilon Systems Solutions does

Epsilon Systems Solutions, Inc. is a 100% employee-owned private defense contractor founded in 1998 by Bryan B. Min, a U.S. Navy Veteran Submariner. Headquartered in San Diego, California, the company operates 20+ locations across the United States (California, Virginia, Florida, Hawaii, New Mexico, Ohio, Missouri) and a wholly-owned Australian subsidiary in Perth, with approximately 1,000+ employees. Its business is organized around four integrated service lines: Navy Service Life Extension Programs (ship repair, modernization, and SUBSAFE-certified submarine work conducted in 125,000+ sq. ft. of facilities near major Navy homeports); C5ISR and Battlespace Management delivered through the Epsilon C5I, Inc. subsidiary (software development, systems engineering, cyber security, and intelligence production platforms including VISION, MARS, and TAF); Engineering and Advanced Products (rugged displays, aircraft ground support equipment, hyperbaric systems, and custom training systems manufactured in ISO 9001:2015 and AS9100D-certified facilities); and Infrastructure and Technical Solutions (GIS, environmental compliance, EHS*desk* software, and Virtual Task Trainer training platforms).

Revenue is generated almost exclusively through U.S. federal government contracts — primarily with the U.S. Navy (NAVSEA, NAVAIR, Type Commanders, Regional Maintenance Centers, Warfare Centers) — under IDIQ, cost-plus, and firm-fixed-price arrangements via GSA Corporate (47QRAA21D005F), SeaPort-NxG (N00178-19-D-7616), GSA ASTRO (47QFCA22D0260), and GSA OASIS+ (47QRCA25DU130, 47QRCA25DU399) contract vehicles. Key customers also include the U.S. Air Force, U.S. Space Force, U.S. Coast Guard, Australian Defence Force (under AUKUS), and defense primes including Lockheed Martin, Raytheon, General Dynamics, and Huntington-Ingalls. Competitive advantage is anchored by rare NAVSEA SUBSAFE certification (one of only five companies worldwide), 100% employee ownership via ESOP, and a leadership bench heavily drawn from former Navy nuclear submariners, retired flag officers, and senior defense industry executives. Strategic priorities include scaling AUKUS-related submarine sustainment work in Australia, expanding C5ISR mission support for programs such as Project Overmatch and Golden Dome, and growing additive manufacturing capabilities for defense supply chains.

Regional players

• Oceaneering International: Oceaneering is a marine engineering and subsea robotics specialist supporting Navy submarine services, diving, and hyperbaric operations from Gulf Coast and overseas hubs. Comparable in submarine-adjacent services and submersible/hyperbaric product lines overlapping with Epsilon's Advanced Products portfolio.
• Thales Australia: Thales Australia supplies naval combat systems, Collins-class sustainment support, and undersea warfare capability under the AUKUS banner. Most relevant regional peer to Epsilon Systems Australia for Collins-class sustainment and future SSN-AUKUS industrial work.

Direct peers

• VSE Corporation: VSE Corporation is a mid-sized federal services and aftermarket distribution company serving the U.S. military with aviation, land, and sea sustainment solutions. Similar scale and customer profile to Epsilon Systems with comparable GSA/NAVAIR support and a federal defense services business mix.
• Serco Inc. (Federal Services): Serco's North American Federal Services division delivers naval and marine engineering, fleet management, and ship repair support across U.S. Navy homeports. Comparable scope of NAVSEA and TYCOM contracts, comparable mid-size scale, and adjacent GSA vehicle holdings.
• Scientific Research Corporation: SRC is a privately-held defense contractor providing engineering, C5ISR, electronic warfare, and lifecycle support to DoD and IC customers. Closely comparable in scale, ownership profile (private/employee-aligned), Navy and IC customer mix, and engineering-led services portfolio.
• Vertex Aerospace (Stow): Vertex Aerospace provides rotary-wing and fixed-wing aviation maintenance, logistics, and sustainment for DoD and commercial customers. Comparable mid-sized federal MRO services profile and similar Navy/Marine Corps customer concentration.
• AMSEC (HII Technical Solutions): AMSEC is a subsidiary of Huntington Ingalls Industries focused on ship repair, modernization, and naval technical services. It directly competes with Epsilon Systems for Navy TYCOM, RMC, and NAVSEA ship repair and AIT work, and is one of the few peers with comparable NAVSEA-certified submarine sustainment capability.

Broad incumbents

• CACI International: CACI provides defense, intelligence, and federal civilian IT and engineering services including C5ISR, electronic warfare, and Navy fleet support. Competes with Epsilon C5I for intelligence production and Navy systems engineering task orders at a larger enterprise scale.
• SAIC: SAIC is a large federal IT and engineering services prime with deep Navy and C5ISR exposure including NAVSEA software, fleet support, and intelligence work. Competes with Epsilon C5I for Navy and IC task orders while operating at materially larger scale across multiple agencies.
• ManTech (KBR): ManTech, now part of KBR, is a leading C5ISR, cyber, intelligence, and mission-IT services provider to defense and IC customers. Directly comparable in C5ISR and intelligence production domain overlap with Epsilon C5I but at meaningfully larger scale.
