About the company

Neptune And Company, Incorporated, a woman-owned small business based in Lakewood, Colorado, delivers environmental science, engineering, and technical consulting services to federal agencies primarily as a prime contractor under indefinite delivery vehicles and GSA Schedule, specializing in quality assurance auditing, statistical analysis, laboratory competency assessments, and data validation for environmental research and remediation programs.

Neptune operates almost entirely as a prime contractor (99% of recent awards) across a highly concentrated customer base. The Environmental Protection Agency dominates the portfolio: EPA's Office of Research and Development accounts for 327 awards and $58.4 million in combined potential value (38% of all awards and 38% of combined potential value), while EPA agencies collectively represent 75% of award count across the top five customers. The Department of Energy's Office of Environmental Management is the second-largest customer by dollar value, with 11 awards totaling $61 million in combined potential value, concentrated on probabilistic performance assessment and statistical decision analysis services for the West Valley Demonstration Project. The Department of the Interior's U.S. Geological Survey, National Park Service, and the CDC round out the active set. This concentration reflects Neptune's positioning as a specialized vendor for environmental compliance and quality services rather than a broad-spectrum contractor.

Neptune holds three primary indefinite delivery vehicles: a $11.0 million single-award IDIQ with EPA's Office of Research and Development (effective through October 30, 2028) for technical quality assurance and statistical support, which has generated 109 task orders totaling $4.6 million; a $20.8 million single-award IDIQ with DOE's Office of Environmental Management (through January 27, 2029) for probabilistic performance assessment and statistical decision analysis on West Valley work, supporting $61 million in combined potential value across 11 delivery orders; and a $1 million single-award IDIQ with USGS (through March 31, 2029) for laboratory auditing services. Neptune also holds two governmentwide multiple-award seats on the OASIS+ platform — the OASIS+ Total Small Business program (awarded December 19, 2024, through December 18, 2029) and the OASIS+ Women-Owned Small Business program (awarded September 30, 2024, through September 29, 2029), each with multi-billion-dollar ceilings. On the GSA Federal Supply Schedule (award date November 10, 2022, through November 9, 2027), Neptune offers 16 labor categories spanning $137.40 to $312.79 per hour, from Staff Scientists with bachelor's degrees and two years of experience through Principal Scientists and Company Managers holding PhDs with 20 years of experience. No security clearances are required for any GSA Schedule roles. Recent Schedule delivery orders include a $1.0 million task order from CDC Pittsburgh (April 1, 2026) for quality assurance regulatory compliance and statistical support in Atlanta through March 2031, and a $249.9 thousand task order from CDC (September 22, 2023) for statistical support completed in September 2025.

Award activity has grown modestly in the recent period, from 28 awards in 2022 to a peak of 36 in 2024, declining to 11 in 2025 and 9 through September 2026. This trajectory reflects the annual task-order cycle typical of EPA ORD and DOE OEM work, where individual orders are smaller and numerous rather than trending toward consolidation. Only 8 awards face ultimate completion in the next twenty-four months (combined potential value $1.1 million), limiting immediate recompete pressure, though the EPA ORD IDIQ's October 2028 expiration and the DOE OEM IDIQ's January 2029 expiration represent material recompete windows for 2027 and 2028.

Neptune delivers services directly rather than through subcontractor teams. Across SCI-reportable contracts, Neptune shows no material sub-engagement: on prime records, zero percent of contractor hours are attributed to subcontractors. In the sub-award space, Neptune holds minimal volume—7 sub-awards (1% of total) as a named subcontractor under four primes: AECOM Technical Services (PFAS investigations and risk assessment support), Battelle Memorial Institute (UXO dredge work), EA Engineering, Science, and Technology (groundwater monitoring work at Kirtland Air Force Base), and Eagle Global Scientific (scientific and technical support to NCEH). These sub-roles are peripheral to the core prime business and do not anchor the company's revenue model.

SCI-reported invoiced revenue provides a narrow view of federal services activity above the $150,000 reporting threshold. In FY2022, Neptune invoiced $1.3 million across 5.4 FTEs. Activity expanded to $3 million across 11.2 FTEs in FY2023, remained near that scale in FY2024 at $3.5 million and 11.6 FTEs, and grew to $3.8 million across 13.4 FTEs in FY2025. On federal services contracts captured in SCI, government-paid rates ran around a median of $138.32 per hour, with the tenth percentile at $117.56 per hour and the ninetieth percentile at $149.79 per hour. The FTE trajectory and pricing posture signal steady-state federal delivery of environmental consulting labor at mid-tier commercial rates, aligned with the GSA Schedule portfolio's position in the mid-to-senior technical professional band. Neither SCI dollars nor FTE counts represent Neptune's total federal revenue or total workforce; they are confined to prime service contracts above $150,000 and exclude goods, grants, classified work, and non-federal activity.

Neptune competes predominantly under unrestricted and small-business set-aside vehicles. The OASIS+ Total Small Business set-aside (December 2024) is the vendor's most recent high-ceiling addition, alongside the existing OASIS+ Women-Owned Small Business seat (September 2024). However, the vast majority of Neptune's revenue flows from two single-award EPA and DOE IDIQ vehicles that do not carry formal set-asides, and which represent mature, stable task-order relationships rather than competitive vehicles. Recent EPA ORD and EPA regional orders show "No Set-Aside Used" consistently, indicating Neptune wins on merit and pricing under unrestricted competition once seated on the primary IDIQ. This posture—leveraging a small-business identity on governmentwide vehicles while drawing most revenue from established sole-source or sole-vendor IDIQs—is typical of specialized environmental consulting vendors with deep agency relationships.
