EOS Inc.

EOS Inc. is a veteran-owned small business manufacturer of military vehicle components and spare parts based in North Charleston, South Carolina, operating as a Subchapter S Corporation and holding a subsidiary, Sidecar Enterprises Inc. The company competes predominantly as a prime contractor (100% of recent awards) under full-and-open procurement and Total Small Business set-asides, with deep specialization in engine accessories, hydraulic systems, brake components, and mechanical assemblies for the Department of Defense.

EOS Inc.'s customer base is heavily concentrated in Defense Logistics Agency sustainment operations. The top five funding agencies account for 98% of recent awards by count, led decisively by DLA Land and Maritime (1,280 awards, $207.6 million combined potential value), followed by DLA Aviation (254 awards, $5 million), DLA Troop Support Hardware (73 awards, $230 thousand), Army Contracting Command Warren (64 awards, $142.2 million), and DLA Troop Support Construction and Equipment (47 awards, $1 million). The two rankings diverge meaningfully: while DLA Land and Maritime dominates both volume and dollars, ACC Warren's dollar share ($142.2 million across 64 awards) reflects larger individual contract values—notably a $4.28 million definitive contract for 40 diesel engine blocks (2815-00-394-9729) awarded May 15, 2025, a $1.855 million delivery order for 69 crankcase units awarded April 16, 2025, and a $26.7 million delivery order for diesel engine repair kits awarded September 18, 2025.

Award activity has grown steadily from 141 orders in 2022 to a peak of 355 in 2024, declining to 223 in 2025 and 54 so far in 2026 (through mid-April). The company faces recompete exposure with 48 awards (combined potential value $59.7 million) reaching ultimate completion within the next twenty-four months, creating near-term risk across active DLA and Army Contracting Command relationships. EOS Inc. holds a substantial portfolio of indefinite delivery contracts with DLA Land and Maritime, structured as single-award vehicles with $250,000 to $350,000 ceilings and one-year terms. Representative high-value examples include a $20.2 million five-year IDIQ for engine-related components (pistons, piston rings, vehicle filler necks, tube crosses) running through February 23, 2031, awarded February 24, 2026; a $1.845 million definitive contract for M1 Abrams tank axial fan impellers (NSN 2930-00-679-5742) to ACC Warren running through February 22, 2030, awarded November 5, 2025; and a $3.89 million modification to deliver crankshaft assemblies and connecting rod pistons (December 17, 2027 completion) awarded April 24, 2025. Work is performed at EOS Inc.'s North Charleston facility with delivery to DLA depots throughout continental United States and overseas locations.

The company's capability footprint centers on discrete military vehicle components: engine parts (camshafts, crankshafts, diesel blocks, pistons, flywheels, cylinder sleeves), fluid management systems (fuel pumps, coolant heaters, fluid filters, swivel joints), brake assemblies (brake drums, brake shoes, segmented rotors), hydraulic and sealing components (seals, gaskets, O-rings, retainer packing, preformed packing), drivetrain parts (gearshafts, axles, tube assemblies, hose assemblies), fasteners and hardware, and bearing assemblies. Top NAICS concentrations are Other Engine Equipment Manufacturing (293 awards) and Rubber and Plastics Hoses and Belting Manufacturing (134 awards). Recent representative examples at various scales include a $567.8K purchase order for 52 exciter ignition components (NSN 2920016111041) awarded November 12, 2025, a $42.6K Total Small Business set-aside for 4,489 engine parts kits (NSN 2815005297992) awarded June 2, 2025, a $15.27 million delivery order for 163 diesel engine repair kits from ACC Warren awarded March 4, 2026 under Total Small Business set-aside, and routine smaller orders for individual components (o-rings, gaskets, fasteners, filters) valued between $50 and $5,000.

EOS Inc. places task orders against five named parent vehicles: an indefinite delivery contract SPE7LX20D0189 (34 task orders, $13.1 million), and blanket purchase agreements W56HZV20AJ016 (27 task orders, $1 million) and W51B2823AJ028 (25 task orders, $1.3 million), alongside multiple DLA Land and Maritime single-award IDIQs awarded throughout 2025 and 2026 with individual ceilings of $250,000 to $350,000 for specific components (adjusting arm belts, camshafts, bevel gearshafts, brake drums, o-rings, mounting brackets, piston spray nozzles, tappet assemblies, brake clutch levers, fluid filters, tie rods, gear clusters, steering components, and brake shoe kits). A Basic Ordering Agreement with ACC Warren for Class IX supplies became effective April 1, 2026, with no dollar ceiling specified, extending through April 1, 2031.

EOS Inc. maintains a single identified subcontractor relationship: a $4K sub-award from Atlantic Diving Supply Inc. for IED interrogation arm (thermal) components awarded April 25, 2024. The source does not identify significant subcontracting activity beyond this entry.

The company's specialization in discrete military vehicle and engine components, coupled with its veteran-owned small business status and established position on multiple DLA sustainment contracts, positions it as a steady supplier of routine spare parts and critical engine components—categories where volume is predictable and competition remains active across small business set-asides and full-and-open procurements alike. Concentrated customer exposure to DLA Land and Maritime (57% of combined potential value), though geographically diversified through DLA depots worldwide, creates both stability through recurring orders and recompete risk as individual one-year and five-year IDIQs approach renewal.
