374Water Announces Minimum Equity Ownership Policy for Board of Directors

DURHAM, N.C., Oct. 15, 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 announced it has implemented a minimum equity ownership policy (the "Equity Ownership Policy") with the members of the Board of Directors (“Board Member”).

Under the terms of the Equity Ownership Policy, each Board Member is required to attain and maintain a minimum ownership level in the Company as set out in the Equity Ownership Policy. Each director must purchase a minimum value of USD $50,000 of shares, the Minimum Equity Ownership Threshold, inclusive of any previously purchased shares, and continuously hold at least the same number of shares initially purchased to meet the requirement irrespective of subsequent changes in stock price. Any future modification of the Equity Ownership Policy that results in a material change to the Minimum Equity Ownership Threshold will require the mutual consent of the Company and the Board of Directors.

“This new policy further aligns shareholder and Director incentives and promotes long-term value creation for the company,” said Stephen J. Jones, Interim President and Chief Executive Officer of 374Water. “We believe 374Water is an exceptional company as we continue to commercialize our AirSCWO technology and focus on strategic partnerships and capital initiatives related to our Waste Destruction Services (“WDS”) business model. Both the Board and management are committed to further unlocking this value for shareholders in the months and years ahead.”
