EOS Inc.

EOS Inc., a veteran-owned Subchapter S corporation based in North Charleston, South Carolina, manufactures discrete military vehicle and engine components as a prime contractor (100% of recent awards) supplying the federal government through firm fixed-price purchase orders, delivery orders, and indefinite delivery contracts. The company competes predominantly under full-and-open and Total Small Business set-asides, with both designations appearing across its prime footprint.

EOS Inc. specializes in engine and drivetrain spare parts, hydraulic and cooling system components, brake assemblies, seals and fasteners, and mechanical assemblies for military vehicle sustainment. Representative work includes a $26.7 million delivery order from Army Contracting Command Warren awarded September 18, 2025, for diesel engine repair kits (NSN 2815-01-500-7584) under a Total Small Business set-aside, a $2.4 million definitive contract from ACC Warren dated April 21, 2026, for fuel injector assemblies (90 units with 90-unit option), and a $1.8 million definitive contract from ACC Warren dated November 5, 2025, for axial fan impellers (NSN 2930-00-679-5742) for the M1 Abrams tank. Recent work also includes a $20.2 million five-year engine-component IDIQ from DLA Land and Maritime awarded February 24, 2026 (SPE7LX-25-R-0050), covering pistons, piston ring sets, vehicle filler necks, and tube crosses with a potential value ceiling of $20.2 million.

Customer concentration is extreme and concentrated in maintenance sustainment. DLA Land and Maritime accounts for 1,311 awards and $211.2 million in combined potential value—73% of the vendor's award footprint by dollars. Army Contracting Command Detroit Arsenal (covering ACC Warren, which issues most Army engine-component awards) accounts for 68 awards and $146.6 million. Together, these two customers represent 98% of EOS Inc.'s recent award coverage by dollar value. DLA Aviation trails significantly with 268 awards worth $5.9 million. This concentration is both a strength (deepened relationships, repeatable sustainment demand) and a risk: EOS Inc. lacks diversification across agency customers or mission sets.

EOS Inc. sits on numerous single-award IDIQs with DLA Land and Maritime, predominantly structured at $250,000 to $350,000 ceilings with one-year terms or until aggregate orders reach the ceiling, whichever occurs first. Representative vehicles include an engine-component IDIQ (SPE7LX20D0189) with 34 task orders and $13.1 million combined potential value, and multiple component-specific IDIQs for camshafts, fluid filters, seals, brake drums, tube assemblies, and mounting brackets. The vendor also holds a Basic Ordering Agreement with ACC Warren dated April 1, 2026, under the BOAST (Basic Ordering Agreement Sustainment Track) program for Class IX supplies with no dollar ceiling specified. Several DLA BPAs appear in the parent-vehicle portfolio, including W56HZV20AJ016 (27 task orders, $1 million combined potential value) and W51B2823AJ028 (25 task orders, $1.3 million combined potential value).

Activity has grown substantially but shows signs of moderation. Awards per year climbed from 141 in 2022 to a peak of 355 in 2024, then contracted to 223 in 2025 and 104 year-to-date in 2026. Over the next twenty-four months, 67 awards with combined potential value of $62.5 million face ultimate completion, triggering recompete exposure for EOS Inc. and recompete opportunity for competitors on routine sustainment contracts.

EOS Inc. holds one subcontract award in the source material: a $0 amount (likely nominal) under Atlantic Diving Supply, Inc., dated April 25, 2024, for an "IED Interrogation Arm (Thermal)." This represents negligible sub-engagement; EOS Inc. operates almost entirely as a prime contractor.

EOS Inc. operates a named subsidiary, Sidecar Enterprises Inc., registered as a for-profit veteran-owned and service-disabled veteran-owned business. No detail is provided on the subsidiary's role or customer relationships, but the naming suggests potential capability expansion or separate legal structure for specialized work.

The vendor's award portfolio spans narrow product categories centered on military vehicle sustainment: top NAICS include Other Engine Equipment Manufacturing (300 awards), Rubber and Plastics Hoses and Belting Manufacturing (135 awards), and Gasket, Packing, and Sealing Device Manufacturing (120 awards). Top PSC categories are Diesel Engines and Components (199 awards), Hose and Flexible Tubing (186 awards), and Hose, Pipe, Tube, Lubrication, and Railing Fittings (134 awards). This framing confirms EOS Inc. as a narrow-spectrum, sustainment-focused supplier with no apparent presence in modernization, integration, or non-DoD civilian federal work.

EOS, Inc. provides partnered business development and program management, full-service logistics solution, and OEM equipment and parts distribution.
