374Water (NASDAQ:SCWO) reported second quarter 2026 revenue of $2.26 million, up about 280% from roughly $0.6 million in Q2 2025, mainly from completing project milestones including the Orange County Sanitation District Factory Acceptance Test. First-half 2026 revenue was $2.8 million versus $1.1 million a year earlier.
Q2 2026 gross profit was $1.98 million with an 87% gross margin, compared with a gross deficit of about $0.3 million and a negative margin in Q2 2025. Operating expenses fell to $3.6 million from $4.3 million, reducing operating loss to $1.6 million and net loss to $2.7 million ($0.15/share) from $4.6 million ($0.32/share).

According to 374Water, it cut annualized operating costs by about $3.2 million, advanced its Waste Destruction Services strategy, secured a long-term Orlando WDS facility agreement, progressed municipal deployments in California, Minnesota, and Kansas, and reported >99.9% PFAS destruction in U.S. Department of Defense testing of its AirSCWO technology.
374Water (NASDAQ: SCWO) announced that the U.S. Department of Defense Defense Innovation Unit issued a Success Memo to partner Arcadis, validating the economic and technical viability of 374Water’s AirSCWO PFAS destruction technology and formally closing the DIU/ESTCP prototype phase.
The Success Memo, under the federal Other Transaction Authority framework, enables federal agencies to move directly to follow-on production awards and procure AirSCWO as a commercial product. This aligns with 374Water’s Orlando Waste Destruction Services hub, which serves PFAS, biosolids, industrial sludges and other difficult waste streams and targets $3–$5 million in annual recurring revenue at initial scale following expansion to 88,000 gallons of onsite storage and upgraded AirSCWO throughput capacity.
374Water (NASDAQ:SCWO) reported preliminary second quarter 2026 revenue of more than $2.2 million, up from $0.6 million in 2025, with first-half 2026 revenue exceeding $2.8 million versus $1.1 million a year earlier. According to 374Water, growth was driven largely by approximately $2.0 million recognized following a successful Factory Acceptance Test (FAT) for the Orange County Sanitation District (OC San) AirSCWO system.
The completed OC San FAT positions the company to invoice about $2.6 million in remaining contract billings and recognize roughly $1.1 million in additional revenue as milestones are met. 374Water also received a $4.8 million order from Olathe, KS, advanced a $600,000 St. Cloud, MN pilot to Phase III, and expanded its Orlando Waste Destruction Services hub to approximately 88,000 gallons of storage capacity. The company entered a strategic MOU with Arcadis focused on federal PFAS destruction opportunities and appointed Charles “Chuck” Weiser as Chief Financial Officer and Richard “Rick” Davis to the Board.
374Water (NASDAQ:SCWO) is highlighting its Air Supercritical Water Oxidation (AirSCWO™) technology, which is designed to permanently destroy organic contaminants such as PFAS “forever chemicals,” pathogens including Cyclospora, pharmaceuticals, biosolids, and industrial waste at the molecular level to support cleaner water and wastewater reuse.
According to 374Water, commercialization efforts include commercial operations at Orlando’s Iron Bridge Water Reclamation Facility, expansion of its Waste Destruction as a Service model, deployments in Olathe (KS), St. Cloud (MN) and Orange County Sanitation District (CA), and Department of Defense-sponsored validation showing >99.9% PFAS destruction across multiple waste streams.
374Water (NASDAQ:SCWO) reported completion of Phase 2 of its mobile AirSCWO deployment at the City of St. Cloud, Minnesota, under a $600,000 Waste Destruction Services contract, and the start of Phase 3. The State of Minnesota is using this campaign, supported by LCCMR and ENRTF, to evaluate AirSCWO for permanent PFAS destruction.
Phase 2 processed Class A biosolids from a Lystek thermal hydrolysis process, including a strong run at up to 12% solids, with all planned sampling completed and performance described as consistent with previous AirSCWO campaigns. Phase 3 has begun on pre-anaerobic digestion sludge, a waste stream previously processed by the company with 97% solids reduction and up to 99.99%+ PFAS reduction in earlier campaigns. According to 374Water, each mobile AirSCWO unit is estimated to have the potential to generate $500,000–$1.5 million in annual revenue, depending on deployment cadence, waste composition, and contract structure, and the St. Cloud project is intended to help build a scalable, recurring mobile services business.
374Water (NASDAQ:SCWO) announced that a U.S. Army Engineer Research and Development Center (ERDC) technical report independently validated its AirSCWO™ technology for destroying PFAS in aqueous film-forming foam (AFFF). The AirSCWO 6 system achieved a total PFAS destruction and removal efficiency of 99.9993% across 42 PFAS compounds, with individual compounds between 99.994% and 100%.
Treated liquid effluent was reported to meet U.S. EPA maximum contaminant levels for all regulated PFAS, indicating potential for direct discharge. Volatile fluorinated stack emissions were near zero, at 0.0005 g/hour versus a PFAS throughput of 16.6 g/hour, and broader organics were reduced to near-non-detect. The ERDC TR-26-19 report, performed under the Army’s Environmental Quality Technology 6.4 Program, supports 374Water’s strategic collaboration with Arcadis to pursue federal and commercial PFAS destruction contracts.
374Water (NASDAQ:SCWO) announced a Memorandum of Understanding with Arcadis U.S. to jointly pursue federal, municipal, and industrial contracts for permanent destruction of PFAS-impacted waste, including aqueous film-forming foam (AFFF), using 374Water’s AirSCWO supercritical water oxidation systems.
The MOU outlines development of turnkey PFAS destruction solutions and regional treatment hubs, with Arcadis expected to lead federal prime contracting, client interface, and regulatory/permitting work, while 374Water provides patented AirSCWO technology, waste destruction services, and system deployment and operation. The collaboration leverages a U.S. Department of Defense–sponsored demonstration in which AirSCWO achieved >99.9% PFAS destruction across hard-to-treat waste streams, including >99.99% destruction in concentrated AFFF. 374Water’s existing Orlando Waste Destruction Services facility will serve as a commercial reference hub, with additional regional hubs anticipated to support a long-duration federal PFAS remediation market.
374Water (NASDAQ:SCWO) appointed Charles “Chuck” Weiser, CPA, as Chief Financial Officer, effective immediately. He succeeds Interim CFO Adrienne Anderson, who will remain as a financial consultant focused on SEC reporting, compliance, and corporate finance activities.
Weiser, already a Board member and long-time investor, brings experience in finance, capital markets, strategic planning, and turnaround management to support commercialization and growth.
374Water (NASDAQ:SCWO), a cleantech and environmental services company, has been added to the Russell Microcap Index, effective after the close of U.S. markets on June 26, 2026.
The company expects enhanced institutional visibility while focusing on deploying its AirSCWO technology, expanding Waste Destruction as a Service, growing recurring revenue, and addressing PFAS and other organic waste streams.
374Water (NASDAQ:SCWO) reported Phase 1 completion of its mobile AirSCWO deployment in St. Cloud, Minnesota under a $600,000 waste destruction services contract. Phase 2 is underway, with steady operations and no major challenges. The pilot runs through mid-September 2026 and may support broader PFAS-destruction adoption.
According to 374Water, early field data align with prior campaigns, and the mobile unit is estimated to generate $500,000–$1.5 million in annual revenue per system, helping build a scalable, recurring mobile services business.
