About the company
Adjoiner Corporation, a minority-owned, Asian-Pacific American-owned small business based in Buena Park, California, delivers electronic security system integration and lifecycle support services to federal defense installations as a prime contractor under full-and-open and total small business set-aside vehicles. The company specializes in intrusion detection systems, access control systems, closed-circuit television systems, and related infrastructure repair and upgrade work across military bases and federal facilities.
Adjoiner's customer concentration is heavily tilted toward Army installation management in the Southwest Region. The top five funding agencies account for 84% of recent award volume, led by the Department of the Army Installation Management Command Southwest Region (78 awards, $13.4 million combined potential value), followed by the Department of the Air Force Space Command (20 awards, $4 million), the Department of Housing and Urban Development Housing Office of Single Family Housing (6 awards, $8.1 million), and smaller sets from Army Medical Command and Air Force proper. The two rankings diverge meaningfully: HUD's potential-value share is anchored by a handful of large awards despite lower award count, while Army Installation Management dominates both volume and dollars. Representative prime work includes a $865.7 thousand firm fixed-price purchase order from the Air National Guard for intrusion detection system infrastructure repair, upgrades, and sustainment services at an Aurora, Colorado facility (performance through September 2029); a $349.2 thousand purchase order from Pacific Air Forces for MSA IDS sensor upgrade work at Kadena Air Base, Okinawa (performance through June 2025); and a $366.9 thousand purchase order from the Air Force for IDS field equipment and network infrastructure replacement in the Munitions Storage Area at Kadena Air Base (performance through March 2026). Recent smaller awards include a January 2026 purchase order from U.S. Space Command for CCTV installation at Cheyenne Mountain Air Force Base ($155.1 thousand) and a January 2026 purchase order from Pacific Air Forces for Vindacator maintenance at Yigo, Guam ($159.8 thousand, performance through September 2028).
Adjoiner holds a Federal Supply Schedule contract (47QSWA23D0017) through the General Services Administration valued at $500 thousand (November 16, 2022 through November 15, 2027), which provides a vehicle for task orders from federal civilian agencies and serves as a parent contract on some defense procurements. The company also places work under Army IDIQs: Indefinite Delivery Contract W911RZ10D0019 (37 task orders, $2.7 million combined potential value), W911RZ15D0006 (12 task orders, $2.5 million), DU205NC14D06 (5 task orders, $738 thousand), and W911RZ11D0005 (3 task orders, $331 thousand). Work is performed at military installations including Cheyenne Mountain Air Force Base and Peterson Space Force Base in Colorado, Kadena Air Base in Okinawa, Andersen Air Base in Guam, and other Army and Air Force locations worldwide. The NAICS profile reinforces the security and construction focus: electrical contractors and wiring installation (63 awards) and security systems services (44 awards) dominate the portfolio, with PSC codes concentrated on physical security and badging support, miscellaneous alarm and detection systems installation, and construction of miscellaneous buildings.
Activity has been episodic, with two awards in 2021 and 2026 and peaks in 2022 (six awards) and 2023 (five awards). Combined potential value across 133 prime awards reaches $31 million, with $22.3 million obligated (72% drawn down). Only one award faces ultimate completion within the next twenty-four months ($160 thousand recompete exposure), indicating a stable installed base with most active work extending into 2025 or beyond. Adjoiner operates exclusively as a prime contractor with no subcontract footprint in the source data.
