Nippon Sanso Matheson, Inc.

Matheson Tri-Gas, Inc., doing business as Aeris, is a foreign-owned manufacturer that supplies industrial, medical, and specialty gases—including aviator's breathing oxygen, liquid nitrogen, liquid oxygen, propellant pressurization gases, and liquid argon—to federal defense, civilian, and research agencies as a prime contractor on full-and-open competitive awards with no preferential set-asides. The company competes across 109 distinct federal customer agencies, with the vast majority of awards concentrated in Defense Logistics Agency Energy delivery orders and purchase orders spanning compressed and liquefied gas supply (PSC codes 4140 and 4210). Matheson Tri-Gas is headquartered in Warren, New Jersey, and classified as a for-profit corporation under primary NAICS 331314 (Industrial Gas Manufacturing).

The customer concentration is extreme and deliberate. Defense Logistics Agency Energy accounts for 7,754 awards and $175.8 million in combined potential value—92% of Matheson Tri-Gas's award count and 74% of its total potential value. This relationship anchors the business. The top five customers by potential value—DLA Energy, NASA Johnson Space Center, Veterans Health Administration (Veterans Integrated Service Network 20), Indian Health Service, and Naval Sea Systems Command—represent 80% of combined potential value. DLA Energy's dominance, combined with the next-ranked customer (NASA JSC) carrying only $5.8 million, reveals Matheson Tri-Gas as a specialized supplier operating almost entirely within the defense logistics ecosystem.

Matheson Tri-Gas holds multiple indefinite delivery contracts with DLA Energy, the largest being a five-year firm fixed-price requirements contract (SPE601-25-R-0310) awarded September 1, 2025, with a $4.29 million ceiling extending through June 30, 2030. That contract covers supply of aviator breathing oxygen (approximately 3.28 million units), liquid oxygen (13,500 tons), liquid nitrogen (5.19 million units), and liquid argon (160,000 pounds) to 44 locations across the U.S. Southeast Region, spanning Air Force bases, Naval air stations, Army depots, Marine Corps air stations, and Coast Guard facilities, with ancillary services including tank rental, emergency delivery, and equipment installation on an F.O.B. Destination basis. The top five parent vehicles (SPE60121D1539, SPE60121D1534, SP060011D1508, SPE60117D1556, SPE60120D1512) collectively account for 4,713 task orders and $15.3 million in combined potential value. Representative awards include a $1.76 million delivery order from NASA Johnson Space Center for liquid propellant fuels and oxidizers (July 1, 2026), a $988,963 purchase order from Indian Health Service for medical gas services to Cheyenne River Health Center in South Dakota (July 7, 2026), and a $504,511 purchase order from Naval Computer and Telecommunications for industrial gas supply to Cutler, Maine, with a five-year performance period through January 20, 2031.

Activity has remained stable, averaging roughly 750 awards per year over the past five years (2022–2025) with 205 awards recorded year-to-date in 2026. However, the recompete cliff is minimal: only 10 awards with ultimate completion in the next twenty-four months carry combined potential value of $2.1 million. This reflects Matheson Tri-Gas's heavy reliance on large, multi-year indefinite delivery vehicles rather than individual purchase orders approaching expiration. The portfolio shows a recent surge in delivery order velocity—over 250 delivery orders placed in the past four months alone (February through early July 2026)—indicating sustained DLA Energy demand.

Matheson Tri-Gas subcontracts minimally: the source lists only two sub-awards, both recent (December 2025–December 2025), under Pantexas Deterrence LLC for Pantex Plant management and JSC Engineering for argon supply. The company operates almost exclusively as a prime, reflecting its role as a direct supplier rather than a system integrator or support services vendor. Place of performance on the majority of awards is Warren, New Jersey (headquarters) or customer sites (military installations, federal offices, hospitals).

The vendor competes without any SBA set-aside designations—all recorded awards are full-and-open or commercial item procurements. This posture, combined with Matheson Tri-Gas's stable high-volume presence across DLA Energy's multiple indefinite delivery vehicles and its consistent receipt of non-set-aside task orders, signals a mature, established federal contractor with commodity-like standing in the compressed and liquefied gas supply market. The foreign ownership status does not restrict access to these awards; the source explicitly notes foreign-owned manufacturer status on multiple recent delivery orders. Federal contractors competing against Matheson Tri-Gas on DLA Energy indefinite delivery contracts or seeking gas supply partners for downstream teaming should expect to face this vendor across the Southeast Region and on national requirements contracts.
