Sri International

Sri International, a non-profit research and development organization headquartered in Menlo Park, California, operates as a prime contractor on 98% of its federal awards, delivering preclinical drug development, biomedical research services, advanced sensor and electro-optical system development, microcircuit fabrication and testing, autonomous systems research, and materials science across defense and civilian agencies without set-aside designations. The organization competes full-and-open across 198 distinct federal customer agencies and holds a diverse portfolio of 7,353 federal awards spanning 1979 to the present, with combined potential value exceeding $125.8 billion and recent annual invoicing around $40 million on SCI-reportable federal service contracts.

Sri International's customer concentration is anchored by defense and health agencies. The National Institute of Allergy and Infectious Diseases leads by potential value ($2.03 billion across 117 awards) through single-award indefinite-delivery vehicles for Interventional Agents Chemistry Services ($50 million ceiling, Sept 2025–Sept 2032) and Interventional Agents Safety and Pharmacokinetics Services ($50 million, Sept 2025–Sept 2032). DARPA follows ($1.6 billion across 342 awards), the Department of the Air Force ($956 million across 937 awards), the Defense Logistics Agency Land and Maritime ($901.5 million across 337 awards), and the National Cancer Institute ($435.6 million across 54 awards). Recent contract work includes a $33.3 million Office of Naval Research definitive contract for research, development, and systems engineering of a 150-foot low-frequency antenna through April 2030; a $10.65 million DARPA definitive contract for the Microsystems Induced Catalysis (MICA) program; an $8.05 million DARPA Intrinsic Cognitive Security (ICS) program contract for cognitive guarantees in mixed reality systems; and a $49 million National Institute of Child Health and Human Development Biological Testing Facility IDIQ (Sept 2026–Sept 2033) for in vivo efficacy validation and preclinical drug evaluation.

Sri International holds multiple flagship indefinite-delivery vehicles anchoring its prime footprint. The Scalable Homeland Innovative Enterprise Layered Defense (SHIELD), a $151 billion multiple-award IDIQ with the Missile Defense Agency (Dec 2025–Dec 2035), procures research, development, prototyping, systems engineering, and disruptive technology development across air, missile, space, cyber, and hybrid threat domains. The Generalized Emulation of Microcircuits (GEM) program IDIQ with DLA Land and Maritime carries a $125.6 million ceiling (Aug 2024–Jan 2030) for design, fabrication, packaging, and microcircuit engineering; the Advanced Microcircuit Emulation (AME) program IDIQ with DLA Land and Maritime is valued at $98.6 million (Feb 2026–May 2031). The National Institute of Neurological Disorders and Stroke Drug Manufacturing and Formulation Program (DMFP) IDIQ spans $49.999 billion (May 2026–May 2036) for API scale-up, formulation, and stability testing. Sri International also holds multiple Other Transaction IDVs with DARPA including vehicles for the Heterogenous Adaptively Produced Photonic Interfaces (HAPPI) program ($7.49 million, March 2025), Flexible Networking Using Intelligent Dialecting (FLUID) ($4.9 million, Sept 2025), and Principles of Undersea Magnetohydrodynamic Pumps (PUMP) ($14.99 million, April 2024), alongside a $25 million DARPA Blanket Purchase Agreement for commercial accelerator support services (Aug 2024–Aug 2027) issuing 60–100 calls annually in the $50–250 thousand range.

On research and biomedical contracts, Sri International maintains selective teaming with research universities and specialized technical firms. Charles River Laboratories serves as a recurring subcontractor on NIAID and NIDA biomedical awards for laboratory animal procurement and preclinical services. The California Institute of Technology partners on the Ultraviolet Explorer (UVEX) program for sensor production, with multiple sub-awards through May 2026. University of Houston collaborates on the Advanced Research Projects Agency-Energy Printed Microreactor for Renewable Energy-Enabled Fuel Production (PRIME-FUEL) cooperative agreement ($2.322 million, July 2026–July 2028) for composite modeling. Princeton University, UC Santa Barbara, Columbia University, and New York University serve as subcontractors on DARPA Intrinsic Cognitive Security (ICS) for formal methods and human-performance assessment. Across SCI-reportable prime contracts, subcontractors account for approximately 7% of total contractor hours, with 110 named subs reported over the source period.

SCI activity captures Sri International's federal services footprint on contracts above the $150,000 threshold, excluding goods and classified work. Invoiced revenue totaled $48.3 million in FY2022, $34.9 million in FY2023, $38.2 million in FY2024, and $49.7 million in FY2025, reflecting 62–89 FTEs per fiscal year. Government-paid hourly rates on prime SCI contracts range from a 10th percentile of $67.82/hr for junior administrative roles to a median of $309.54/hr and a 90th percentile of $956.48/hr for senior technical staff, consistent with Sri International's positioning as a research organization delivering advanced scientific and engineering services. The GSA Multiple Award Schedule (MAS) portfolio spans 52 labor categories from $85.66/hr for junior data analysts to $487.49/hr for senior researchers, with education requirements from high school to doctorate and no security-clearance positions offered.

In grants, Sri International acts as recipient across NSF, NIH, Department of Energy, and Department of Interior programs. Recent awards include a $1.257 million NIH Office of the Director Trans-NIH Research Support grant (Sept 2025–Aug 2027) investigating thermoregulatory physiology of menopausal hot flashes through peripheral skin cooling; a $1.259 million National Institute on Aging Aging Research grant (Sept 2025–Aug 2027) for glymphatic MRI and biomarker discovery in aging with HIV; a $999,887 NSF STEM Education grant (Aug 2025–July 2028) for professional skills badging in career and technical education with Evergreen Valley College as sub-recipient; and a $2.322 million Department of Energy ARPA-E cooperative agreement (July 2026–July 2028) for recyclable carbon fiber-reinforced polymers with University of Houston as sub-recipient. Awards in the next twenty-four months total 93 contracts and grants (combined potential value $300 million) facing recompete.

Recent activity has moderated from a peak of 137 awards in 2024 to 99 in 2025 and 44 through September 2026, reflecting normal cyclicality in large multi-year research portfolios. Sri International competes exclusively full-and-open without small-business set-asides, positioning itself as a qualified large research organization for complex federal R&D across defense, biomedical, energy, and education domains. The organization's federal contracting posture emphasizes prime delivery with selective, mission-critical subcontracting; approximately 8% of reported hours on SCI prime contracts flow to subcontractors, concentrated in specialized laboratory services, materials science, and formal methods expertise that complement Sri's in-house research infrastructure.
