DURHAM, N.C., Nov. 12, 2025 (GLOBE NEWSWIRE) -- 374Water Inc. (NASDAQ: SCWO) ("374Water" or the "Company"), a global leader in organic waste destruction technology and services for the industrial, municipal, and federal markets, today reported its financial and operational results for the third quarter ended September 30, 2025.

“The third quarter of 2025 was underscored by ongoing service deployments and the continued commercialization of our Super Critical Water Oxidation (“SCWO”) technology,” said Stephen J. Jones, Interim President and Chief Executive Officer of 374Water. “For example, we successfully completed a commercial-scale waste destruction service project at Clean Earth’s Detroit, MI facility as part of a Department of Defense (“DoD”) project. For six weeks we executed per- and polyfluoroalkyl (“PFAS”) destruction of multiple concentrated waste streams at commercial Treatment, Storage, and Disposal Facilities (“TSDF”) using our AirSCWO 6 System. We also successfully deployed our AirSCWO technology to a Colorado School of Mines and DoD Environmental Security Technology Certification Program project aimed at comparing technology solutions to destroy PFAS contaminated wastes. Both efforts demonstrated our ability to destroy PFAS-impacted waste streams as a treatment option for DoD installations impacted by PFAS.

“During the quarter we signed a waste destruction services (“WDS”) collaboration agreement focused on PFAS destruction with Crystal Clean, a leading provider of environmental and waste management solutions. Crystal Clean is an ideal partner to enable our WDS business to scale rapidly and support growing demand across a wide array of market verticals and waste streams. We intend to grow the WDS business over the next several years, establishing multiple WDS operations at TSDF partner facilities across North America. WDS will generate recurring revenues with customers demanding total waste treatment with our AirSCWO technology.

“Most recently, we secured an order from the City of Olathe, KS ("Olathe") for the sale and deployment of an AirSCWO 6 system and a related pre-treatment and dewatering system. Olathe will utilize the AirSCWO process at its wastewater treatment facility to assess its potential as a sustainable alternative to traditional sludge management practices and disposal methods. We also recently began processing our award by the State of North Carolina for WDS to destroy AFFF utilizing AirSCWO technology. In the first phase of this waste destruction service project, we will treat 1,000 gallons of AFFF. If selected for the second phase, we could treat up to an additional 28,000 gallons of AFFF.

“On the financial front, we have strengthened our balance sheet, utilizing our at-the-market facility which generated proceeds of approximately $7.0 million, extending our anticipated cash runway into the second quarter of 2026.

“Looking ahead, we are focused on successful waste destruction of PFAS and other waste streams utilizing our AirSCWO system at current project deployments and accelerating the conversion of a growing pipeline of opportunities. With the recent announcements of revenue generating service and capital equipment sales, we are projecting 2026 revenue to be in the $6-8 million range. We look forward to additional milestones and announcements in the months ahead,” concluded Jones.

Third Quarter 2025 Financial Summary

• For the third quarter of 2025, revenue totaled $760,000 compared to $81,000 in the prior year. The company’s business has been focused on the development and commercialization of its AirSCWO systems to fulfill current projects and prepare for additional revenue growth. The approximate $679,000 increase in revenues was primarily due to an increase in our service revenues of approximately $643,000 from the completion of waste destruction service projects, and $36,000 in capital equipment sale revenues.
• Total operating expenses increased 64% to $4.6 million for the three months ended September 30, 2025, compared to $2.8 million in the prior year period. The increase was primarily owed to expanded operations including a $0.9 million increase in compensation and related expenses, an increase of $0.3 million in research and development, and an increase of $0.8 million in general and administrative expenses.
• Net loss for the three months ended September 30, 2025, was $4.3 million, as compared to$2.7 million in the prior year. Net loss increased due to continued investment in commercialization and increased operational costs.
• Revenue for 2025 calendar year is projected to be approximately $4 million based upon current expectation of deliverables for the fourth quarter.
• Cash and cash equivalents as of September 30, 2025, was $0.9 million, as compared to $10.7 million as of December 31, 2024. As of September 30, 2025, working capital was $1.9 million, compared to $4.5 million as of September 30, 2024.
• Based upon our current cash position, including the $7.0 million raised from the at-the-market facility, and expected billings and related collections, we project to have adequate cash to support our business plans into Q2 2026.
