Multiple Deployments Scheduled throughout 2025 to Showcase AirSCWO Technology

Launched Waste Destruction Services and Signed RCRA Part B TSDF Partner Agreement to Expand Onsite Operations

New Executive Team and Director Appointments to Drive Commercial Trajectory

DURHAM, N.C., May 15, 2025 (GLOBE NEWSWIRE) -- 374Water Inc. (NASDAQ:SCWO) ("374Water") (the "Company"), a global leader in waste destruction technology for the municipal, federal, and industrial markets, today reported its financial and operational results for the first quarter ended March 31, 2025.

"The first quarter of 2025 was focused on our robust, actionable backlog and pipeline and accelerating our proprietary AirSCWO ("AS") system's commercial trajectory," said Chris Gannon, President and CEO of 374Water. "Building on the success of our AS system deployed to the City of Orlando's Iron Bridge Water Reclamation Facility, we continued to make progress during the quarter for the expected deployment to Orange County Sanitation ("OC San") in the second half of the year. We were also awarded a contract by the State of North Carolina to destroy 1,000 gallons of aqueous film forming form ("AFFF") containing per- and polyfluoroalkyl ("PFAS"), this contract could increase by up to 29,000 gallons in a subsequent phase.

"To support our commercial rollout and operational execution, we continued to buildout our executive team and Board. Raj Melkote, Chief Technology Officer, brings tremendous expertise in strategy, product commercialization, new product development, and core technology innovation enabling us to more rapidly scale our business and further ruggedize and refine our AS technology. Stephen Jones, our newest independent director, has extensive experience in corporate leadership including as CEO of Covanta, board roles, and expertise in environmental services and industrial gases and chemicals. His appointment adds critical and valuable components to the board with his decades of industry experience and, equally important, his key relationships that will open doors with new partners. Most recently we welcomed James Pawloski as an Advisor and have also nominated him to serve as an independent director. As the former CEO of Regeneration and Recovery Solutions at Veolia North America, we expect his perspective and extensive experience in waste, wastewater, and environmental solutions to support our commercialization.

"The U.S. Environmental Protection Agency ("EPA") recently announced major actions to combat per- and polyfluoroalkyl substances ("PFAS") contamination and we believe these actions and the regulatory environment for PFAS will create strong demand tailwinds for our AirSCWO platform designed to destroy a wide variety of non-hazardous and hazardous organic wastes reaching non-detect or below EPA required levels, including PFAS. We expect the planned actions to quantify liabilities and expand PFAS remediation efforts could drive significant interest in our technology as companies look to limit liability and public funds are allocated for cleanup efforts.

"Looking ahead, with the completion of numerous municipal, federal, and industrial waste destruction demonstrations on a wide variety of solid and liquid waste streams, we are generating demand across these markets. We have made significant progress ruggedizing and optimizing our AS system and are continuing to improve our AS technology. We are completing the manufacturing of an AS1 and an AS6 unit and anticipate launching and beginning to accept third-party waste streams at our initial Waste Destruction Services ("WDS") operations. In addition to our OC San deployment, we expect multiple additional deployments throughout 2025 to showcase the AS system. We look forward to additional milestones and announcements in the months ahead," concluded Gannon.

First Quarter 2025 Financial Summary

For the first quarter of 2025, revenue totaled $0.5 million compared to $0.3 million in the prior year. The company's business has been focused on the development and commercialization of its supercritical water oxidation (SCWO) systems. Revenue generated was primarily from equipment manufacturing services and services, specifically a full-scale demonstration and treatability studies during the three months ending March 31, 2025, and March 31, 2024, respectively. During the three months ended March 31, 2025, we completed a full-scale demonstration for a customer resulting in an increase in our service revenues of $376,000, offset by a decrease in equipment manufacturing revenue of approximately $162,000.
Total operating expenses increased 106% to $3.9 million for the three months ended March 31, 2025, compared to $1.9 million in the prior year period.
The increase was primarily due to an increase of $0.9 million in general and administrative expenses, an increase in professional fees of $0.5 million, and an increase in compensation and related expenses of $0.6 million.
- The increases in general and administrative expenses stem from increased stock-based compensation, continued efforts to establish our executive team as well as the relocation of our manufacturing facility and continued commercialization and growth efforts.
- The increase in our professional fees are primarily because of increased legal fees as a result of a litigation settlement and recruiting fees related to the increase in headcount.
- The increase in compensation is due to increased staffing as the company increases operations.
Net loss for the three months ended March 31, 2025, was $3.7 million, as compared with $2.0 million in the prior year.
Cash and cash equivalents as of March 31, 2025, was $6.9 million, as compared to $10.7 million as of December 31, 2024. As of March 31, 2025, working capital was $8.7 million, compared to $11.7million as of March 31, 2024.
