Exponent Inc.

Exponent Inc., a Menlo Park, California-based engineering and scientific consulting firm, operates as a prime contractor across 397 of its 399 federal awards (99%), competing full-and-open with no set-aside designations, delivering expert witness services, human factors and vehicle safety research, contract management, and technical engineering analysis to 71 distinct federal agencies.

Exponent's customer concentration tilts toward transportation safety, defense, and justice work. The National Highway Traffic Safety Administration anchors the largest dollar commitment at 12 awards worth $236.7 million combined potential value, driven primarily by a $120 million indefinite delivery contract for human factors research awarded in September 2024 with completion in March 2030. The Department of the Army ranks second across both award count (49 awards, $96.1 million) and a separate count for Training and Doctrine Command (34 awards, $61.6 million); combined, Army commands account for 83 awards totaling $157.7 million. The Department of Justice—split between the U.S. Attorney's Offices (43 awards, $3 million) and the Environment and Natural Resources Division (22 awards, $3.7 million)—reflects Exponent's sustained litigation support footprint, with 64-plus expert witness contracts. The Defense Human Resources Activity (11 awards, $51.2 million) and the Department of State Bureau of Consular Affairs (43 awards, $42.8 million) round out the top-five customer list. These five customer groups account for 72% of combined potential value across the portfolio.

Exponent's vehicle position is distributed across five principal indefinite delivery and multiple-award vehicles. The GSA Professional Services Schedule hosts 102 task orders worth $31.8 million. The Army's Indefinite Delivery Contracts W50RAJ21D0002 and W91CRB07D0013 together carry 46 task orders and $64.2 million in potential value. A $16.4 million delivery order with the Defense Human Resources Activity through the GSA Multiple Award Schedule (MAS) invoiced $3.2 million across 3.5 FTEs in FY2025. The NHTSA Human Factors IDIQ, awarded in September 2024 at $120 million, supports three delivery orders issued to date: a $676,485 order for drive-mode design best practices (completion March 31, 2029), a $749,924 order for alert and warning characteristics for advanced driver assistance systems (September 30, 2029), and a $479,857 time-and-materials order for human factors heuristics (March 19, 2027). Exponent also holds delivery orders under NHTSA's Vehicle Electronic Systems Safety (VESS) IDIQ and serves on the Federal Energy Regulatory Commission's liquefied natural gas technical expertise vehicle ($3.3 million, option year one exercised September 2025, completing September 2030).

Award activity has been volatile. Exponent closed 22 awards in 2022, declined to 11 in 2023, rebounded to 18 in 2024, then slowed to 8 in 2025 and 11 year-to-date in 2026. Twenty-three awards totaling $30.4 million in combined potential value face ultimate completion inside the next twenty-four months, creating recompete exposure.

Service Contract Inventory reporting, which captures federal service contracts above the $150,000 threshold, shows SCI-reported invoiced revenue of $5 million in FY2022, $8.3 million in FY2023, $415 thousand in FY2024, and $3.2 million in FY2025, deployed across 10.8, 10.8, 0.6, and 3.6 FTEs respectively. This SCI data reflects a partial and declining slice of Exponent's federal services footprint and does not capture goods, micro-purchases, or classified work. On SCI-reportable prime contracts, government-paid labor rates ran a median of approximately $328 per hour, with 10th-percentile rates around $206 per hour and 90th-percentile rates around $433 per hour. Exponent self-performed 100% of reported contractor hours across SCI-recordable prime contracts, engaging no named subcontractors on those awards.

Exponent's capability footprint centers on human factors research and vehicle safety systems evaluation—particularly driver monitoring systems, intelligent speed adaptation, advanced driver assistance systems, and pedestrian collision countermeasures for NHTSA. Engineering and technical consulting dominate the award portfolio: 210 awards fall under Engineering Services (NAICS 541330), 34 under Research and Development in Physical and Engineering Sciences, and 11 under Testing Laboratories. Expert witness services account for 66 awards (typically small-dollar litigation support purchase orders to the U.S. Attorney's Offices, DOJ Civil Division, and DOJ Environment and Natural Resources Division), all priced at time-and-materials rates with completion dates extending to 2028–2031. Army work spans program management, analysis-modeling-and-prototyping technical consulting, travel support, and task-based services under Army single-award IDCs. The Bureau of Engraving and Printing ($3.2 million, MAS) covers production engineering and manufacturing data analysis. The Bureau of Overseas Building Operations awarded a $643 thousand delivery order for scheduling and real estate services on the Milan embassy project (Italy, completion March 2027). The Consumer Product Safety Commission ($459 thousand) funded lithium-ion battery testing for electric mobility devices. Federal Highway Administration ($36 thousand) contracted for geotechnical expert support on a California road project. Exponent also holds two sub-awards: a $14.3 million sub under Research Triangle Institute on the Streams IV ETSC contract (May 2024) and a sub-recipient award from the National Academy of Sciences for speed-management research tools (June 2026).

Recent grant work includes a $841 thousand Defense Health Agency Military Medical Research and Development award (CFDA 12.420, completion September 2026) for beryllium exposure mortality risk assessment, and an earthquake simulation and structural analysis grant from an NSF-affiliated acquisition office (FY2023, $39 thousand equivalent).

Exponent competes predominantly as a prime contractor in full-and-open competitions on established GSA and agency vehicles, with minimal subcontracting footprint and no set-aside participation. The vendor's federal revenue derives from a diverse base of 71 agencies, with concentration in transportation safety research and litigation support rather than a single customer dependency.
