Sri International

Sri International, a non-profit research and development organization headquartered in Menlo Park, California, operates as a prime contractor on the vast majority of its federal awards (99% prime, 1% sub), competing full-and-open without set-asides, delivering advanced scientific and technical services across defense, civilian health research, energy, and education domains. The organization holds a diverse portfolio spanning 197 federal agencies and has accumulated over $125 billion in combined potential value across 7,353 awards since 1979, with recent fiscal-year activity averaging 86 awards annually and $40 million in SCI-reported invoiced revenue.

Sri International's concrete capability portfolio centers on preclinical drug development, biomedical research services, microcircuit fabrication and testing, advanced sensor and electro-optical system development, materials science research, and autonomous systems research. Representative prime work includes a $9.96 million cost-plus-fixed-fee contract with the Office of Naval Research for the Predicting the Ocean Environment for Navy Tactical Undersea and Surface Operations (PONTUS) program (award December 2025, extending through December 2030 at Menlo Park); a $33.3 million sole-source effort for research, development, and systems engineering of a blast low-frequency high-power 150-foot antenna complex at Stanford University, also with ONR (May 2025, completing April 2030); a $16.8 million definitive contract with DARPA for advanced magnetometer research and sensor development with university partners including Princeton University, Twinleaf LLC, and George Mason University (awarded April 2024, concluding May 2026 at Princeton, New Jersey); and multiple task orders under National Institute of Allergy and Infectious Diseases master IDIQs for nonclinical safety testing, animal model development, and interventional agent chemistry services, individually valued at $830 thousand to $16.2 million. SCI-reportable data across FY2022–FY2024 shows invoiced revenue of $48.3 million (FY2022), $34.9 million (FY2023), and $38.2 million (FY2024), reflecting a relatively stable federal services baseline, with median government-paid hourly rates around $309.48/hr and senior technical labor pricing through $929/hr; across prime SCI-reportable contracts, subcontractors account for roughly 8% of total contractor hours, with 90 named subs performing specialized technical work.

Customer concentration is highly distributed across defense and civilian agencies. The top five agencies by award count account for 51% of awards and span the Navy (1,065 awards, $15 million), the Army (1,015 awards, $12.4 million), the Air Force (937 awards, $956.1 million), the Defense Threat Reduction Agency (378 awards, $32.6 million), and DARPA (338 awards, $1.59 billion). By potential value, the ranking shifts sharply toward biomedical research: the National Institute of Allergy and Infectious Diseases (117 awards, $2.03 billion potential value) leads all agencies, followed by DARPA ($1.59 billion across 338 awards), the Air Force ($956.1 million across 937 awards), the Defense Logistics Agency Land and Maritime ($898 million across 334 awards), and the National Cancer Institute ($435.6 million across 54 awards). This signals both substantial Navy and Army order frequency and much larger individual dollar commitment from NIH institutes for long-duration drug development and biomedical research initiatives.

Sri International holds prominent indefinite delivery vehicles anchoring task-order activity across multiple agencies. The Defense Logistics Agency Land and Maritime Advanced Microcircuit Emulation (AME) program awarded a $98.6 million single-award IDIQ on February 2026 (extending through May 2031) covering design, fabrication, packaging, and engineering for microcircuit solutions; the Generalized Emulation of Microcircuits (GEM) program IDIQ carries $125.6 million ceiling (August 2024–January 2030) with task orders ranging from sub-thousand-dollar microcircuit procurements to $32.6 million assembly and procurement efforts involving major subs Amplitech Group (Spectrum Semiconductor Materials), Golden Altos Corporation (IC packaging and wafer assembly), and Engineering and Solutions Technology LLC (testing). The Missile Defense Agency awarded the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) multiple-award IDIQ with a multi-billion placeholder ceiling (December 2025, ending December 2035) supporting research, prototyping, systems engineering, and weapon design across air, missile, space, cyber, and hybrid threat domains. National Institute on Drug Abuse issued a Chemistry, Manufacturing and Controls (CMC) multiple-award IDIQ valued at $49.9 million (July 2026–July 2031) for formulation development, cGMP manufacturing, analytical method development, and stability testing across small molecules, peptides, biologics, and gene therapy vectors. The National Institute of Neurological Disorders and Stroke Drug Manufacturing and Formulation Program (DMFP) multi-award IDIQ carries a $50 million ceiling (May 2026–May 2036) supporting API scale-up and manufacturing for candidate molecules in the Blueprint Neurotherapeutics Network. DARPA maintains multiple standing vehicles with Sri International: a Blanket Purchase Agreement for commercial accelerator support services ($25 million, August 2024–August 2027) with recent calls in the $200–400K range for research program and accelerator advisory services; multiple Other Transaction IDVs including ones for the Flexible Networking Using Intelligent Dialecting (FLUID) research program ($4.9 million, awarded September 2025), the Intrinsic Cognitive Security (ICS) program ($8.05 million, awarded June 2024), the Principles of Undersea Magnetohydrodynamic Pumps (PUMP) program ($14.99 million, April 2024), and others across artificial intelligence quantification, photonic interfaces, and emerging computational methodologies. National Institute of Allergy and Infectious Diseases holds two single-award indefinite delivery vehicles: one for Interventional Agents Chemistry Services ($50 million, September 2025–September 2032) and another for Interventional Agents Safety and Pharmacokinetics Services ($50 million, same dates), both supporting drug candidate development and toxicology evaluation.

Activity trajectory shows modest recent growth followed by a slight decline: 94 awards in 2022, 102 in 2023, 137 in 2024 (a 34% annual increase), 98 in 2025 (28% decrease), and 23 in 2026 (source cutoff is July 2026). This trajectory reflects both the underlying size of Sri's prime contract portfolio and completion-driven recompete cycles rather than declining federal demand. Recompete exposure in the next twenty-four months totals 97 awards with combined potential value of $411.4 million, a material but manageable recompete cliff driven primarily by multi-year research vehicle maturations and option-period expirations across DARPA, NIH, and defense agency programs.

Teaming structure reflects Sri International's role as both a prime integrator and a selective user of specialized subcontractors. Across SCI-reportable prime contracts, subcontractors contribute roughly 8% of total labor hours, indicating Sri International builds and executes most delivery internally; however, on major research programs, the organization routinely engages research universities and specialized technical firms for distinct workstreams. DARPA research awards demonstrate this pattern: the PWND2 (Provably Weird Network Deployment and Detection) program ($3.6 million, August 2025) names University of Chicago, Princeton University, Cornell University, and Algoritmo Sapiente LDA as major subs for formal methods, network modeling, and cryptography expertise; the ICS program ($8.05 million) engages UC Santa Barbara, Columbia University, New York University, and Virginia Tech for material characterization, probe-based analysis, and human-performance model development; the MACARONI magnetometer program ($16.8 million) teams with Princeton University, George Mason University, and Twinleaf LLC for sensor design, radiofrequency magnetometer development, and noise analysis. On biomedical research, Charles River Laboratories frequently appears as a sub for laboratory animal procurement and preclinical services (multiple NIAID and NIDA awards), and Oregon Health & Science University and Leland Stanford Junior University serve as sub-recipients on NIH grants for disease research and neuroimaging analysis.

Federal grant footprint covers major civilian research agencies. National Science Foundation awards include a $540 thousand project grant for hydroxyl energy transfer mechanisms in upper atmospheric nightglow (Division of Atmospheric and Geospace Sciences, CFDA 47.050, April 2026–March 2029), a $649,967 grant for collaborative programming models in K-12 computer science education (Division of Research on Learning, CFDA 47.076, October 2025–September 2028), a $999,887 award for professional skills badging in career and technical education (Division of Undergraduate Education, August 2025–July 2028), and a $438,685 grant for infrared atmospheric band nightglow emission analysis (August 2025–July 2028). National Institutes of Health awards include a $1.26 million grant from the Office of the Director for menopausal hot-flash thermoregulation research (Trans-NIH Research Support, CFDA 93.310, September 2025–August 2027), a $1.26 million National Institute on Aging grant for glymphatic imaging biomarkers in HIV-infected aging populations (CFDA 93.866, September 2025–August 2027, with Leland Stanford Junior University as a sub-recipient for DTI analysis), and multiple awards from the National Institute on Drug Abuse for toxicology studies and drug candidate development. Department of Energy awarded a cooperative agreement for the Printed Microreactor for Renewable Energy Enabled Fuel Production (PRIME-FUEL) program with the University of Houston as partner (September 2024–September 2027), developing a modular catalytic microreactor for CO2-to-methanol conversion. Institute of Education Sciences, National Science Foundation, National Institute of Justice, Office of Special Education and Rehabilitative Services, and Bureau of Justice Assistance have all issued grants to Sri International for STEM education research, forensic speaker identification bias mitigation, early childhood data collection support, and school trauma intervention initiatives.

GSA Schedule presence supports civilian and defense agency task-order activity with 52 active labor categories spanning data analysts ($85.66–144/hr), administrative and technical support ($162–203/hr), and senior researchers ($264–487/hr) across high school to doctoral education levels with no security clearance requirements. This broad-based labor portfolio enables rapid staffing of small-to-medium-scope civilian agency consulting and research support engagements without full competitive procurement.

Corporate structure lists multiple subsidiaries under the Sri International parent, including Palo Alto Research Center (PARC) LLC and Ravenswood Solutions Inc., reflecting historical organizational evolution and specialized research center operations; PARC has been separately identified on defense and advanced research contracts. The organization remains entirely tax-exempt non-profit, a posture that aligns with its positioning as a federal research partner and differentiates it from for-profit contractors in grant and research-focused procurements.
