About Addx Corporation
Addx Corporation, a service-disabled veteran-owned small business (SDVOSB) headquartered in Alexandria, Virginia, operates as a prime contractor (99% of awards) delivering logistics, technical engineering, IT modernization, facilities operations, and professional services across the Department of Defense, civilian agencies, and the intelligence community. Addx holds active SBA certifications as both a Veteran-Owned Small Business and Service-Disabled Veteran-Owned Small Business through December 6, 2027, and competes predominantly under SDVOSB and Total Small Business set-asides on governmentwide vehicles.
Addx's recent prime footprint centers on defense logistics and technical support work. Representative awards include a $31.7 million firm fixed-price delivery order from Air Education and Training Command (March 2025, OASIS+ SDVOSB) for logistics and technical support covering communications security products, force protection, weapons storage security systems, and COMSEC maintenance, with performance in San Antonio, Texas through September 2030; a $16.9 million delivery order from Air Combat Command (November 2025, OASIS+ SDVOSB) for Global Accelerated Logistics Enterprise Support System engineering support to Air Force Global Strike Command at Barksdale Air Force Base through November 2030, leveraging subcontractors Applied Research Associates, Inc. and Siertek, LLC; and a $6.59 million delivery order from Air Combat Command (March 2026, OASIS+ SDVOSB) for facility operations and project management support at U.S. Strategic Command (Offutt Air Force Base) through March 2031. The vendor also holds positions on two multi-billion-dollar defense vehicles: the OASIS+ SDVOSB IDIQ (with a no-specified-ceiling multiple-award structure through September 29, 2029) and the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) IDIQ (Missile Defense Agency, $151 billion ceiling, through December 28, 2035, full and open competition), which opened Addx to strategic defense modernization opportunities in prototype development, systems engineering, and AI-enabled capabilities across air, missile, space, and cyber domains.
Customer concentration shows heavy weight on Navy and Air Force work by dollar value, but award volume concentration differs. By awards count, Addx serves 60 agencies; the Department of Commerce (USPTO) leads count at 82 awards ($208.2 million combined potential) but represents largely legacy and turnover work. By potential value, the Department of the Navy Naval Sea Systems Command anchors the portfolio at 6 awards carrying $72.55 billion combined ceiling — a structural outlier driven by the SHIELD vehicle award. Defense Information Systems Agency follows with 16 awards ($55.8 million potential), and the Federal Aviation Administration with 5 awards ($2.02 billion potential). GSA Federal Acquisition Service places 12 awards ($112.7 million potential), and the Department of Veterans Affairs Strategic Acquisition Center Frederick places 17 awards ($68.9 million potential).
Addx's vehicle footprint reflects SDVOSB and small-business posture across primary contracting roads. The OASIS+ SDVOSB IDIQ and OASIS+ Total Small Business Set-Aside IDIQ (awarded December 2024, $999.999 billion ceiling through December 18, 2029) anchor the near-term pipeline with delivery orders flowing from multiple Air Force commands, the Department of Labor, and the Defense Information Systems Agency. Addx also holds a position on the Eglin Wide Agile Acquisition Contract (EWAAC, $46 billion ceiling, Air Force Materiel Command, through September 9, 2031) and the Joint All Domain Command and Control Support IDIQ ($950 million ceiling, Air Force, through May 28, 2030), though activity on both is minimal. GSA Multiple Award Schedule (MAS) positions carry defense IT support orders — a $8.94 million DISA delivery order (September 2025, Fort Meade) for J-3/5/7 Operations and Strategic Support, and a $35.3 million Department of Labor delivery order (April 2023, through April 2028) for OSHA Information System support services. The vendor also participates in the Electronic FAA Accelerated and Simplified Tasks (eFAST) BPA, from which a $5.3 million BPA call (June 2025, Alexandria) provided training and content development support to the FAA's Airports Office of Compliance through July 2026.
On GSA Schedule, Addx offers 24 unique labor categories spanning foundational cloud roles ($51.15/hr) through director-level IT infrastructure and cloud positions ($277.85/hr), with senior program management spanning $154–$176/hr; education requirements range from associate to master's degree with no security-cleared roles offered. Across SCI-reportable service contracts (FY2022–FY2024), Addx invoiced $30 million in total prime federal services revenue across a declining trajectory: $9.6 million in FY2022 (41.2 FTEs), $11.6 million in FY2023 (45.7 FTEs), and $8.8 million in FY2024 (38.2 FTEs). Government-paid median rates ran around $132.85/hr across those contracts, with 10th percentile around $71.48/hr and 90th percentile around $306.12/hr. Across SCI-reportable prime contracts, Addx subcontracts approximately 31% of contractor hours to named subs (22 subcontractors reported), indicating a balanced prime-delivery model leaning moderately toward internal capacity.
Four awards face ultimate completion in the next twenty-four months with combined potential value of $66.6 million, creating near-term recompete exposure. Activity has been episodic — five awards in 2022, four each in 2023 and 2024, nine in 2025, and one in the first quarter of 2026 — suggesting pipeline concentration rather than sustained volume growth.
