Nexus Group, LLC

Nexus Group, LLC, a Charlotte, North Carolina-based SBA 8(a) certified small business, delivers specialized maintenance, repair, calibration, and technical support services for scientific and medical laboratory equipment to civilian federal agencies and the Department of Veterans Affairs as a prime contractor on purchase orders and indefinite delivery contracts. Nexus Group is Hispanic American-owned and self-certified as a small disadvantaged business, with 8(a) certification expiring October 2032. The firm competes predominantly in total small business set-asides and unrestricted full-and-open competitions, with recent awards split roughly evenly between set-aside and non-set-aside designations.

Nexus Group's capability portfolio centers on field service for analytical and diagnostic instrumentation—mass spectrometers (Thermo Orbitrap, Q Exactive), chromatography systems (UPLC, HPLC, GC-MS), centrifuges, tissue processors, PCR systems, flow cytometers, ultrasound and imaging systems, and specialized laboratory equipment across research and healthcare settings. Representative work includes a $2.5 million Army Corps of Engineers contract for instrument services at the Engineer Research and Development Center in Vicksburg covering maintenance of up to 51 instruments; a $1.3 million Defense Health Agency contract for laser and X-ray tube maintenance at Womack Army Medical Center; a $404 thousand USGS contract for laboratory equipment maintenance at the National Water Quality Laboratory in Lakewood, Colorado; and a $390 thousand VA contract for Siemens imaging equipment maintenance in Brooklyn. The portfolio also includes smaller, recurring purchases for equipment-specific support—$243 thousand for NICHD maintenance, $274 thousand for USDA NBAF X-ray equipment, and numerous $20–$100 thousand annual service agreements across NIH institutes and VA networks.

Customer concentration is distributed across civilian and VA networks with no single agency dominating. The Defense Health Agency leads by award count (18 awards, $2.9 million) and potential value, followed by FDA (17 awards, $1.3 million) and VA's Veterans Integrated Service Network 17 (8 awards, $1.2 million). NICHD, NCI, and VA's VISN 2 and VISN 22 each account for significant activity. About 38 percent of awards cover the top five agencies by count, and 41 percent of combined potential value concentrates in the top five by dollars. Activity grew sharply year over year—from 13 awards in 2022 to 49 in both 2024 and 2025—and remains elevated in 2026 (42 awards in nine months). Fifty awards with a combined potential value of $5.9 million face ultimate completion within the next twenty-four months, creating significant recompete exposure and opportunity for competitors.

Nexus Group holds three published parent vehicles: a Blanket Purchase Agreement with VA VISN 1 for histology equipment service (ceiling $92,400; two task orders issued, $47 thousand combined value through 2030); a single-award indefinite delivery contract with VA VISN 16 for Roche Diagnostics benchmark stainer maintenance (ceiling $85,500; two delivery orders, $35 thousand combined value through 2029); and a single-award indefinite delivery contract with VA VISN 4 for laboratory equipment support at VA Pittsburgh (ceiling $247,500; one base-year delivery order of $49,500 through 2031). Work is primarily on firm fixed-price purchase orders under NAICS 811210 (Electronic and Precision Equipment Repair and Maintenance) and PSC J066 (Maintenance/Repair/Rebuild of Equipment—Instruments and Laboratory Equipment), with secondary work under PSC J065 (medical and veterinary equipment). Nexus Group operates as a 100 percent prime contractor with no recorded subcontract activity in the source data, meaning the vendor does not appear in sub-award records and does not anchor larger primes through teaming.
