Business Overview: 374Water Inc. (NASDAQ: SCWO)

---

Executive Summary

374Water Inc. is a Nasdaq-listed industrial technology company commercializing AirSCWO, a supercritical water oxidation (SCWO) platform that destroys organic and PFAS-contaminated waste streams rather than storing, burying, or incinerating them. Incorporated in Delaware in 2005 (originally as Vyrex Corporation) and reorganized through a 2021 reverse merger with the privately held 374Water, Inc., the company is headquartered in Morrisville, North Carolina, and builds its systems at a manufacturing site adjacent to Orlando's Iron Bridge Regional Water Reclamation Facility.

374Water matters because it is one of only a handful of companies racing to commercialize a technology capable of permanently destroying "forever chemicals" (PFAS) rather than merely concentrating or transferring them, at a moment when U.S. federal and state regulators are tightening PFAS disposal rules. The company remains pre-commercial scale: full-year 2025 revenue was just $215,037, down from $445,445 in 2024, and it carries a going-concern qualification tied to its cash position ($3.2 million at December 31, 2025) against a $20.98 million net loss for the year.

1. Core Business Model & How They Work

374Water generates revenue through a hybrid model layered on top of one core technology: selling capital equipment, leasing systems, operating Waste Destruction Services (WDS) sites itself or with partners, and performing laboratory/testing and field operations-and-maintenance work.

[ Organic/PFAS Waste Collected ] -> [ AirSCWO Unit (Supercritical Water + Air) ]
    -> [ Continuous Oxidation: >99.99% Destruction ]
    -> [ Recovered Water, Minerals, Heat ] + [ Equipment Sale / Lease / WDS Fee Revenue ]

Key Operational Drivers

1. Proprietary AirSCWO Technology: Licensed in part from Duke University, AirSCWO runs organic waste and air through water held above its supercritical point, oxidizing contaminants in a continuous process the company reports destroys at least 99.99% of target compounds in testing, including PFAS.
2. Scaling Product Line: 374Water is moving from a single mobile demonstration unit (AS1) to a standardized mid-size unit (AS6, ~6 metric tons/day) and plans larger AS30 and bespoke AS100+ systems, so unit economics should improve as deployments move from one-off demos toward repeatable installations.
3. Waste Destruction Services (WDS): Rather than selling every customer a capital asset, 374Water is building its own or jointly-operated destruction sites (its first hub opened at Iron Bridge in Orlando in 2025) so it can also earn recurring, service-based revenue per ton destroyed.
4. Government and Municipal Pull: Much of near-term demand is driven by regulatory pressure — EPA PFAS limits, DoD/FAA PFAS remediation mandates, and state biosolids rules — which the company is pursuing through demonstration contracts (e.g., with the Defense Innovation Unit at Clean Earth's Detroit facility, and at Peterson Space Force Base) intended to convert into commercial orders.

3. Competitive Landscape

374Water competes against both alternative PFAS-destruction technology developers and incumbent waste-disposal methods.

• Other SCWO/advanced destruction developers: Revive Environmental (commercializing supercritical water oxidation technology originally developed with Battelle) and Aquagga (mobile supercritical/subcritical water oxidation units) are the closest direct technology competitors, both also chasing PFAS-destruction contracts with municipalities and the federal government.
• Emerging alternative technologies: Plasma-based and electrochemical oxidation processes are being developed by other entrants as alternative PFAS-destruction routes.
• Conventional disposal methods: Incineration, landfilling, anaerobic digestion, lagooning, and lime stabilization remain the default (and far cheaper, where regulators still allow them) ways utilities and industrial generators currently handle biosolids and PFAS-laden waste.

374Water's main differentiator versus Revive Environmental/Aquagga is less about the underlying chemistry (all use supercritical/near-critical water oxidation) and more about commercial execution: who can first prove reliable, continuous, revenue-generating operation at municipal scale.

4. Strategic Strengths & Risks

Strengths

• Regulatory tailwind: EPA PFAS drinking-water limits, state biosolids restrictions, and DoD/FAA PFAS remediation mandates are creating demand for a technology that destroys rather than relocates PFAS — 374Water does not have to create this market from scratch.
• Duke University license and early technical lead: 374Water's underlying IP and multi-year head start building and operating commercial-scale AirSCWO units give it demonstrated, third-party-witnessed destruction performance (99.99%+) that newer entrants must still prove.
• Flexible revenue model: The combination of equipment sales, leasing, and WDS lets 374Water capture value across customers who want to own a system versus those who'd rather pay per ton destroyed.

Risks

• Minimal, declining revenue and going-concern doubt: FY2025 revenue fell to $215,037 (from $445,445 in 2024) against a $20.98 million net loss and only $3.2 million of cash at year-end — the 10-K explicitly discloses substantial doubt about the company's ability to continue as a going concern.
• Unproven at scale: Larger units (AS30, AS100+) are still in design; commercial-scale performance and reliability are not yet established the way the business plan assumes.
• Government budget dependence: A large share of near-term demand runs through DoD, DoE, and FAA programs and municipal budgets, all of which can shift with appropriations cycles and political priorities.
• Direct technology competition: Revive Environmental and Aquagga are pursuing the same municipal and federal PFAS-destruction contracts with comparable underlying technology, so 374Water's lead is execution-based, not a structural moat.

6. Summary Conclusion

374Water sits at the center of a genuine, regulator-driven need — destroying rather than merely storing PFAS and other hard-to-treat organic waste — with a technology that has demonstrated strong lab- and pilot-scale destruction rates. Its business model intentionally layers equipment sales, leasing, and recurring Waste Destruction Services so it is not solely dependent on one-off capital purchases. The central risk is survival through scale-up: revenue remains minimal and declining, cash is thin, the FY2025 10-K carries a going-concern qualification, and close technology competitors (Revive Environmental, Aquagga) are racing for the same early municipal and federal contracts — meaning 374Water's biggest near-term test is commercial execution and financing, not whether the underlying chemistry works.
