About 4ES Corporation
4ES Corporation, doing business as 4ES Corp, is a San Antonio-based SBA 8(a)-certified small disadvantaged business that operates exclusively as a prime contractor (100% of recent awards) providing administrative support, health services, IT applications support, and specialized technical services to federal agencies under 8(a) sole-source and competitive set-asides. The company is minority-owned and Hispanic American-owned, structured as a Subchapter S corporation, with 8(a) certification active through July 2029.
Customer concentration is extreme and CDC-anchored. The Centers for Disease Control and Prevention Atlanta office (CDC Pittsburgh) accounts for 21 awards and $27.3 million of the combined potential value—55% of the vendor's $49.1 million portfolio. The Air Education and Training Command follows with 13 awards and $8.9 million (18% of total). The Department of Justice Bureau of Prisons Field Acquisition Office, Air Force Materiel Command, and Air Combat Command round out the top five. Together, these five customers cover 94% of potential value across all awards. This concentration presents both strength—deep incumbent relationships with dominant customers—and recompete risk: eleven awards worth $9.1 million reach ultimate completion inside the next twenty-four months.
4ES Corp's capability portfolio spans three distinct domains. CDC work centers on data abstraction (Multi-Agency Data Control Program, $4.4 million definitive contract awarded September 2023), administrative and health services (NCHHSTP administrative services, $2.4 million; animal health laboratory and administrative services, $1.4 million; laboratory assistant support, $2.4 million), and specialized technical support (data management, quality management systems). Air Education and Training Command and Air Combat Command work focuses on IT applications support ($4.5 million single-award IDIQ awarded September 2024, with delivery orders through June 2027), audiovisual and video teleconference system design, installation, and maintenance ($627 thousand audio-video renovation project, $463 thousand unclassified video teleconference system upgrade), and facility infrastructure (security camera systems, intercom systems). The Bureau of Prisons awards—under a $4.7 million single-award IDIQ with the Field Acquisition Office (ultimate completion June 2026)—deliver radiologic technician, dental hygienist, physician, and phlebotomist services at United States Penitentiary Atwater. The Navy Bureau of Naval Personnel has awarded smaller contracts for pastoral counselor support ($557 thousand), gospel services ($221 thousand), and assistant organist services.
Vehicle position concentrates on two single-award IDIQs. The Air Education and Training Command IT applications support IDIQ ($4.5 million, 8(a) sole source, through June 2027) generated two task orders totaling $2.1 million. The Bureau of Prisons Field Acquisition Office medical services IDIQ ($4.7 million, 8(a) sole source, through June 2026) has generated four delivery orders totaling $984 thousand. 4ES Corp also holds a GSA Federal Supply Schedule (Multiple Award Schedule) contract awarded October 2022 through October 2027 with no set-aside designation. The schedule comprises 137 labor categories spanning IT services, health IT services, and management consulting, with hourly rates ranging from $45.87 to $335.85—entry-level clinical laboratory technicians and biologists at the low end, senior health IT systems engineers and management strategy practitioners commanding rates above $300/hr. No security-cleared positions are offered.
SCI-reported activity on federal service contracts above the $150,000 threshold shows $11.7 million invoiced across FY2022–FY2024 (FY2022: $3.1 million across 8.2 FTEs; FY2023: $5.3 million across 14.1 FTEs; FY2024: $3.3 million across 11.9 FTEs). This reflects a peak in FY2023 and a contraction to FY2024. Across SCI-reportable prime contracts, 4ES Corp paid government-sourced hourly rates median around $89/hr, with the 10th percentile at $62/hr and the 90th percentile at $340/hr. The vendor subcontracts on approximately 14% of prime-contract hours across SCI records, with seven named subcontractors reported. This teaming posture indicates 4ES Corp builds most delivery capacity in-house but engages subs for specialized or overflow labor, particularly on health and clinical services.
Activity trajectory shows volatility: twelve awards in 2022, four in 2023, eight in 2024, six in 2025, and one in the first quarter of 2026 (year-to-date). The FY2023 contraction and subsequent recovery suggest either contract consolidation on the vendor's side or shifts in customer procurement patterns. Award volume remains modest relative to potential value, reflecting reliance on large fixed-price and time-and-materials definitive contracts and IDIQs rather than multiple small task orders. The eight awards completing in the next twenty-four months facing recompete create pressure to defend incumbent positions, particularly with CDC and Air Education and Training Command, which together represent 73% of current potential value.
