Maddox Industrial Transformer, LLC

Maddox Industrial Transformer, LLC, a for-profit limited liability company based in Greer, South Carolina, manufactures, sells, rents, repairs, and delivers power distribution and specialty transformers to federal agencies as a prime contractor (72% of recent awards) and subcontractor. The vendor competes under no set-aside categories in its prime work; recent awards show mixed small business and full-and-open designations, with a Total Small Business set-aside appearing on two of six 2024 prime awards.

Maddox's federal capability footprint centers on transformer procurement and emergency replacement across power distribution applications. Representative prime work includes a $196,570 firm fixed price purchase order from the Naval Air Warfare Center for a 440MR transformer (completed August 2025), a $107,424 Total Small Business set-aside purchase order from Federal Correctional Institution Seagoville for emergency transformers (September 2024), a $72,218 order from Veterans Integrated Service Network 22 for sixteen replacement units spanning 75 KVA, 45 KVA, and 30 KVA three-phase dry-type transformers with copper windings and NEMA Class ANN construction (July 2026), and a $24,093 order from GSA Federal Acquisition Service for a remanufactured 500 KVA three-phase padmount transformer destined for Naval Air Station Joint Base Charleston-Goose Creek (September 2026). In subcontract roles, Maddox supplies transformers to Bechtel National for NASA Space Launch System Mobile Launcher 2 design and construction (June 2025), to Triad National Security for Los Alamos National Laboratory management and operations (August 2025), and to ASRC Federal Facilities Logistics for general-purpose dry-type and padmount transformer installations under multiple task orders (2024–2025).

Customer concentration is low and fragmented across 16 distinct agencies. The top five customers by potential value — Department of the Air Force, Naval Air Systems Command, Federal Correctional Institution Seagoville, Veterans Integrated Service Network 22, and GSA Federal Acquisition Service — account for 87% of combined potential value ($778 thousand of $892 thousand total), but no single customer dominates. The vendor holds seats on three IDCs (70RSAT18D00000001, SPE8E324D0002, SPE8E324D0010), each carrying one task order. Federal work is grounded in NAICS 336412 (Power, Distribution, and Specialty Transformer Manufacturing) with ten categorized awards and secondary work in facilities support and electrical contracting. Activity has been episodic — two awards per year in 2020–2021, then a jump to six in 2024 and three in 2025, with the most recent award in September 2026. Combined dollars obligated ($1.5 million) exceed combined potential value ($892 thousand), indicating a mix of firm fixed price completions and option exercises across the portfolio.
