About the company
Flatwater, Incorporated, a tribally-owned, SBA 8(a)-certified small disadvantaged business subsidiary of Ho-Chunk, Inc., operates as a federal prime contractor delivering energy engineering, facilities maintenance, technical support services, and healthcare personnel staffing across Indian Economic Enterprise set-asides and competitive 8(a) procurements. The company is headquartered in Winnebago, Nebraska, and competes predominantly under tribal-ownership and 8(a) set-aside categories across a $50.19 billion combined potential-value footprint anchored by two large IDIQs and a positioned seat on the 8(a) STARS III GWAC.
Flatwater's recent activity accelerated sharply in 2026, with nine awards year-to-date (through October 1) after a relatively flat 2023–2025 period. The portfolio spans energy and mineral resource development support for the Bureau of Indian Affairs, facilities maintenance for the Air Force, and clinical and administrative staffing for the Indian Health Service, Department of the Army, Department of Treasury, and Coast Guard. Representative work includes a $4.67 million delivery order (September 2026) for Division of Energy and Mineral Development technical support to the BIA Central Office under Indian Economic Enterprise set-aside, covering renewable energy engineering, oil and gas engineering, geospatial analysis, and data center operations at multiple locations including Winnebago, Nebraska; Lakewood, Colorado; and Fort Berthold, North Dakota. Flatwater also holds a single-award IDIQ (IND17PC00190) with the BIA Division of Energy and Mineral Development valued at $46 million through May 12, 2027, against which six task orders have been issued totaling approximately $24.2 million in combined ceiling value since May 2022. A more recent healthcare example is a $1.9 million firm-fixed-price purchase order (October 1, 2026) from the Indian Health Service for registered nursing and public health nursing services at the Yakama Indian Health Clinic in Toppenish, Washington, running five years through September 2031 with a performance guarantee of 200 labor hours per CLIN and stringent clinical documentation and patient education standards.
Customer concentration sits heavily with tribal-focused agencies and facilities. The BIA's two regional acquisition offices — Albuquerque and Central Office — together account for 17 awards and $157.3 million in combined potential value (82% of non-GWAC dollars). The Air Force Air Combat Command commands six awards and $11 million, driven by four delivery orders for Computer Room Air Conditioning maintenance at Offutt Air Force Base, Nebraska, issued under a single-award IDIQ (FA460026D0002) valued at $9 million through December 2030 with four task orders to date totaling $1.5 million. The Indian Health Service holds two awards worth $3.5 million. GSA Federal Acquisition Service accounts for two awards totaling $50.01 billion in combined potential value — the 8(a) STARS III GWAC (awarded February 23, 2022, ceiling $50 billion, ultimate completion July 1, 2026) and a $13 million GSA Professional Services Schedule contract — but the source indicates no visible task-order activity has been drawn against either vehicle in Flatwater's recent work mix.
On the parent-vehicle side, Flatwater operates under three primary IDIQs: the $46 million BIA DEMD single-award contract (IND17PC00190) supporting nine task orders, the $46 million BIA DEMD single-award contract (140A1622D0010) supporting seven task orders with $30.3 million combined potential value, and the $9 million Air Force CRAC maintenance single-award IDIQ (FA460026D0002) with four task orders. The portfolio is 100% prime work with no sub-award activity, and Flatwater maintains minimal subcontractor reliance — across SCI-reportable prime contracts, subcontractors account for an average 1% of total contractor hours, with five named subcontractors engaged overall. This posture reflects Flatwater's strategy of self-performing technical and personnel delivery rather than acting as a prime aggregator.
Service Contract Inventory captures $21.4 million in invoiced revenue across FY2022–FY2025, with a declining FTE trajectory: 44.2 FTEs in FY2022, 41.0 in FY2023, 24.9 in FY2024, and 18.5 in FY2025. Government-paid hourly rates on federal services contracts range from $57.60 per hour (10th percentile) to $104.51 per hour (90th percentile), with a median of $83.69 per hour, consistent with technical and nursing-labor positioning. In the next twenty-four months, only one award (the BIA Division of Energy and Mineral Development delivery order valued at $4.7 million, ultimate completion May 12, 2027) reaches recompete window, signaling minimal near-term recompete exposure outside potential renewal cycles on the two large BIA IDIQs.
Flatwater's capability footprint aligns with Ho-Chunk, Inc.'s tribal economic-development mission: energy engineering, renewable and oil-and-gas resource development, geospatial analysis, facilities and HVAC maintenance, software development, healthcare staffing (registered nurses, licensed practical nurses, administrative support), and technical support across 70-plus labor categories. The company operates with administrative oversight in Winnebago, Nebraska, and performance locations spanning tribal territories and federal facilities in the Mountain West and Upper Midwest.
