Arizona Tribune - 374Water Reports Second Quarter 2026 Financial Results; Revenue Increases More Than 280% Year-Over-Year

MORRISVILLE, NC / ACCESS Newswire / August 18, 2026 / 374Water Inc. (NASDAQ:SCWO) ("374Water" or the "Company"), a leading cleantech and environmental services company deploying supercritical water oxidation technology for the destruction of PFAS and other organic waste streams, today reported financial results for the second quarter ended June 30, 2026.

Revenue for the second quarter of 2026 was $2.26 million, compared with approximately $0.6 million in the second quarter of 2025, representing an increase of approximately 280% quarter-over-quarter, driven by the completion project milestones, most notable the Orange County Sanitation District ("OC San") Factory Acceptance Test, and associated revenues. Revenue for the first six months of 2026 was $2.8 million, compared with approximately $1.1 million for the same period in 2025.

Gross profit for the quarter was $1.98 million, representing a gross margin of 87%, compared with a gross deficit of approximately $0.3 million and a negative gross margin in the second quarter of 2025.

"The second quarter marked an important achievement for 374Water, driven by our successful completion of the OC San Factory Acceptance Test, which enabled us to recognize approximately $2.0 million in revenue and demonstrate meaningful commercial progress," said Danny Bogar, Chief Executive Officer of 374Water. "Beyond the revenue milestone, the greater accomplishment is what our team and technology have proven - AirSCWO can reliably destroy biosolids at the source and at scale. This milestone allows us to begin invoicing the remaining $2.6 million of the OC San contract as we achieve additional contractual milestones and, more broadly, demonstrates that AirSCWO is ready to address the massive and growing biosolids challenge-starting in California and extending across the United States."

Financial Position and Outlook

During the first half of 2026, 374Water continued to focus on strengthening its financial position while advancing the commercialization of AirSCWO™ and the development of its recurring Waste Destruction Services ("WDS") business model.

The Company has also taken action to reduce its operating costs by approximately $3.2 million on an annualized basis, while prioritizing capital toward commercial deployments and revenue-generating opportunities.

Operational Accomplishments

Our team has been intensely focused on one objective: turning AirSCWO into a scalable Waste Destruction Services business while executing our projects. In just the last several months our team has achieved a series of milestones that solidify the foundation for that business:

• Secured our Orlando WDS facility through a long-term agreement with the City of Orlando, establishing an attractive operating location and the foundation of a significant regional waste destruction hub network.

• Expanded our relationship with the City of Orlando, creating the framework to grow our WDS operations and processing additional difficult waste streams using AirSCWO.

• Achieved >99.9% PFAS destruction in U.S. Department of Defense testing, providing important third-party validation of AirSCWO for a Federal priority and one of the most pressing human health and environmental challenges.

• Executed a strategic collaboration agreement with Arcadis, bringing together 374Water's destruction technology with one of the world's leading environmental engineering and consulting organizations to jointly execute commercial and government opportunities.

• Received additional validation from the U.S. Army Corps of Engineers, further demonstrating our ability to destroy PFAS and other recalcitrant compounds.

• Earned the coveted DIU Success Memo - "Golden Ticket" - through our partnership with Arcadis, establishing an important contracting pathway for AirSCWO to access and address the millions of gallons of AFFF stockpiles across all branches of the Department of Defense and elsewhere in the Federal Government.

Taken together, these represent the building blocks of our WDS business and Company as a whole: mounting demand, contract mechanisms, world-class partners, technology validation, government approval, established facilities, and pathways to revenue.

We Continue to Execute and Build the Infrastructure to Scale

While advancing our WDS strategy, which is critical for growth and market penetration, our team has continued to execute on our existing municipal commitments and expanding the capabilities needed to support the next stage of 374Water's growth:

OC San, California: Successfully completed the Factory Acceptance Test for our AirSCWO system, a major contractual and technical milestone, with delivery to Orange County, California scheduled for October and unlocking an additional $2.6 million of contract value and anticipated follow-on installations.

St. Cloud, Minnesota: Our approximately $600,000 deployment is nearing completion, with the demonstration program expected to wrap up in September, adding another important municipal operational reference.

Olathe, Kansas: Advancing our contracted $4.8M deployment and preparing for launch, further expanding our municipal footprint and demonstrating growing adoption of the technology.

Orlando Infrastructure: On the back of our expanded relationship with the City of Orlando, we are building much more than a WDS facility. Orlando is becoming an operational center for 374Water, with expanded machine shop, fabrication, electrical panel, R&D and testing capabilities, as well as an engineering hub to support our systems and future deployments.

"We have accomplished a tremendous amount in a very short period of time-and there is much more ahead," concluded Bogar. "We are simultaneously delivering for our existing commitments, expanding our WDS business to reach more customers, creating durable partnerships that open business pipelines and meet growing demand, and building the infrastructure and capabilities to scale our AirSCWO technology, our services, and our business."

374Water provided a comprehensive update on its recent commercial accomplishments and strategic initiatives on August 11, 2026.
