Neptune And Company, Incorporated

Neptune And Company, Incorporated, a woman-owned small business headquartered in Lakewood, Colorado, provides environmental science, engineering, and technical consulting services to federal agencies as a prime contractor on 99% of recent awards. The company specializes in quality assurance audits, statistical analysis, laboratory assessments, data validation, probabilistic performance assessment, environmental modeling, and risk assessment — delivering these capabilities predominantly through single-award and multiple-award IDIQs with EPA, DOE, USGS, and GSA rather than competing full-and-open. Neptune holds SBA certifications as a women-owned small business and competes across both set-aside vehicles (OASIS+ Total Small Business and OASIS+ Women-Owned Small Business programs, both with multi-billion-dollar ceilings through 2029–2030) and unrestricted full-and-open task orders, reflecting a customer base that values its specialized environmental compliance and scientific consulting expertise.

Customer concentration is acute and stable. The Environmental Protection Agency's Office of Research and Development dominates the footprint: 328 awards (54% of recent prime volume) with a combined potential value of $61.3 million. The Department of Energy's Office of Environmental Management anchors the second-largest customer relationship: 11 awards with a combined potential value of $61 million, almost entirely for West Valley Demonstration Project probabilistic performance assessment work. GSA Federal Acquisition Service, USGS, the National Park Service, and the National Oceanic and Atmospheric Administration round out the active set. Together, the top five customers account for 75% of awards and 91% of combined potential value, and the two dollar leaders (EPA-ORD and DOE-OEM) are nearly equal despite EPA placing far more orders — EPA issues numerous small task orders while DOE issues fewer, larger awards. This concentration means recompete risk on the EPA-ORD IDIQ ($11 million, expiring October 2028) and DOE-OEM IDIQ ($20.8 million, expiring January 2029) will materially affect Neptune's volume.

The EPA-ORD relationship anchors Neptune's operational footprint. The vendor holds a single-award IDIQ valued at $11,025,777 through October 30, 2028. Since award in October 2023, EPA-ORD has issued over 100 task orders under this vehicle, including recent delivery orders for quality assurance support for Superfund site remediation (CIBA Operable Units, Olin, Stauffer Chemical sites), PFAS data validation and audits, spatial analysis modeling support, laboratory competency assessments, and development of the ProUCL software tool for statistical analysis of environmental data. Work spans multiple EPA offices — the Office of Research and Development itself, the Office of Air and Radiation, and EPA Region 4 — with place of performance distributed across Denver, Cincinnati, Atlanta, Washington DC, Ada, Oklahoma, and New York. With the exception of the EPA relationship, Neptune's customer base is highly diversified: outside EPA and DOE, no single agency represents more than $4.6 million in potential value, and the vendor serves 24 distinct federal agencies without dominant concentration at any one office.

Neptune also holds a $20,811,746 single-award IDIQ with DOE's Office of Environmental Management through January 27, 2029 for probabilistic performance assessment and statistical decision analysis services to the West Valley Demonstration Project. The vendor has received three major delivery orders under this IDIQ — a $9.79 million order (January 2026), an $8.525 million order (June 2022), and a $2.475 million order (December 2022) — all for West Valley environmental remediation, erosion control effectiveness, and related PPA work performed in Cincinnati, Ohio. On the GSA side, Neptune holds a Federal Supply Schedule contract through November 2027 with a $1 million ceiling, offering 16 labor categories ranging from Staff Scientists at $137.40/hr to Principal Scientists and Company Managers at $312.79/hr, all holding bachelor's to doctorate degrees with no security clearance requirement. The vendor also sits on two OASIS+ multiple-award IDIQs awarded in 2024 — the OASIS+ Total Small Business program and the OASIS+ Women-Owned Small Business program — both with multi-billion-dollar ceilings through 2029, though task order volume on these vehicles has not yet materialized in the source data.

Activity has grown modestly. Neptune received 28 awards in 2022, 25 in 2023, and 36 in 2024, with 11 awards in 2025 and 7 to date in 2026. The sharp drop in 2025–2026 reflects the source's recency cutoff and the vendor's dependence on task orders issued under standing IDIQs rather than new prime contract competitions. Eight awards (combined potential value $999 thousand) reach ultimate completion within the next twenty-four months, presenting moderate recompete exposure. The most material recompete risk lies with the EPA-ORD IDIQ expiring October 2028 (currently valued at $11 million in ceiling) and the DOE-OEM IDIQ expiring January 2029 (currently valued at $20.8 million), collectively anchoring roughly $82 million in potential value across 339 awards.

On GSA and SCI-reported service contract activity, Neptune delivered roughly $7.8 million in SCI-reportable invoiced revenue across FY2022–FY2024, with 5.4 FTEs in FY2022 growing to 11.6 FTEs in FY2024. Government-paid hourly rates on SCI-reportable prime contracts cluster around a median of $138.32/hr, with the 10th percentile at $117.56/hr and 90th percentile at $149.79/hr — positioning Neptune as a mid-tier cost provider for environmental science and engineering labor. The vendor builds its own delivery teams: across SCI-reportable prime contracts, subcontractor hours represent 0% of total contractor hours, indicating Neptune delivers directly rather than relying on deep subcontractor engagement. The vendor does subcontract to larger primes on environmental remediation and risk assessment work — named subcontract primes include AECOM Technical Services, Battelle Memorial Institute, EA Engineering Science and Technology, and Eagle Global Scientific — but this activity represents 1% of Neptune's overall award footprint by count, confirming Neptune's operational model as a direct-delivery prime.

Neptune's competitive posture centers on its specialized expertise in environmental compliance auditing, statistical analysis, laboratory quality management systems, and probabilistic performance assessment for federal environmental remediation missions. The company has no presence in defense, cybersecurity, IT modernization, or federal consulting outside the environmental domain, and its customer set is restricted to civilian environmental and research agencies. The concentration of value in two large IDIQs (EPA and DOE), the narrow domain focus, and the reliance on task order volume from standing contracts rather than new prime wins create a profile of a successful niche environmental consulting vendor with stable but cyclical federal revenue tied directly to EPA and DOE task order releases and recompete timing.

Neptune and Company provides hands-on consulting services for environmental management problems in the following areas:project planning, statistics, environmental modeling, risk assessment, QA and Chemistry, Training and Communications.
