About the company

Social & Scientific Systems, Inc., a subsidiary of publicly traded DLH Holdings Corp., is a prime contractor delivering epidemiology support, clinical research coordination, data management, and public health research services to the National Institutes of Health and the Centers for Disease Control and Prevention on full-and-open federal service contracts with no set-aside designation. The company operates from Silver Spring, Maryland, with work performed across multiple HHS locations including Durham, North Carolina and Westlake, Maryland.

Social & Scientific Systems competes almost exclusively as a prime contractor (100% of recent awards) across a diverse portfolio of research support and administrative services. The top NAICS categories span Office Administrative Services (421 awards), Administrative Management and General Management Consulting Services (105 awards), and Research and Development in Physical, Engineering, and Life Sciences (73 awards), with PSC coding dominated by Support-Professional and Support-Management services. The company holds a $320 million single-award IDIQ from the National Cancer Institute's Division of Cancer Epidemiology and Genetics through June 2027 for field and biospecimen support services, a $75 million multiple-award IDIQ from the Administration for Community Living through January 2029 for community living programs, and several agency-wide IDIQs from NIEHS under contract HHSN273201600002I that generated 34 task orders valued at $85.6 million combined potential value. Recent representative prime work includes a $4.76 million Clinical Research Unit staffing support delivery order to NIEHS (September 2026, base year September 2026–August 2027), a $2.7 million Predictors of Puberty Study clinical research support delivery order to NIEHS (September 2026–September 2031), a $14.3 million Epidemiology Coordinating Committee support order from the National Institute of Child Health and Human Development under the GSA Multiple Award Schedule (April 2022–April 2027, with $3 million invoiced in FY2024), and a $13 million statistical support order for NIEHS divisions through May 2027.

Customer concentration tracks heavily toward HHS research institutes. The top five customer agencies by award count account for 60% of awards: the CDC Office of Acquisition Services leads with 414 awards ($232 million combined potential value), followed by the CDC proper (214 awards, $481 thousand), NIEHS (82 awards, $858.7 million), NIH broadly (38 awards, $51 thousand), and the NIH Office of the Director (32 awards, $9.3 million). By dollars, concentration is more pronounced: NIAID anchors $1.44 billion (17 awards), NIEHS contributes $858.7 million (82 awards), NIH's Office of Logistics and Acquisition Operations carries $542.2 million (10 awards), HHS Administration contributes $531.1 million (16 awards), and NCI accounts for $375.5 million (18 awards) — together representing 64% of combined potential value. The vendor's largest parent vehicles are the CDC-funded IDIQs HHSD200200010047I and 200200010047 (398 and 395 task orders respectively, $38–40 million each), Mission Oriented Business Integrated Services (52 task orders, $41 million), and the NIEHS IDIQs noted above.

SCI-reported invoicing of $157.5 million across FY2022–FY2025 reflects work at scale: FY2022 produced $37.7 million across 130 contract-level FTEs, FY2023 grew to $43.8 million across 202 FTEs, FY2024 held at $46.8 million with 182 FTEs, and FY2025 (partial-year) posted $29.2 million across 88.9 FTEs. These SCI figures capture service contracts above the $150,000 reporting threshold and exclude goods, products, and classified work; they represent a strict subset of the vendor's total federal services revenue. On federal services contracts captured in SCI, median government-paid rates ran around $118/hr, with the spectrum spanning $79.74/hr at the tenth percentile to $297.29/hr at the ninety-ninth percentile. The GSA labor portfolio spans 81 categories from Service Specialist 1 at $41.29/hr through Senior Subject Matter Expert roles priced at $319.04/hr, reflecting education from high school through master's degrees with no security-clearance requirements across the portfolio.

Social & Scientific Systems self-performs the vast majority of its work: across SCI-reportable prime contracts, subcontractors accounted for an average of 4% of total contractor hours, with 29 named subs reported across the portfolio. The vendor maintains three named subcontract relationships under Research Triangle Institute primes on the Medical Expenditure Panel Survey Medical Provider Component (February 2026, December 2024, December 2023) and acts as a sub-recipient under the University of Michigan's National Dementia Workforce Study grant (May 2024). Sixteen awards (combined potential value $119.7 million) complete within the next twenty-four months, creating recompete exposure. The vendor's activity footprint has grown from 22 awards in 2021 through a low of four in 2022–2023, rebounding to five in 2024 and twelve through mid-2026, reflecting recent acceleration in NIH and CDC task-order placement.
