374Water Taps Finance Vet to Steer Green Tech Commercialization

MORRISVILLE, S.C. – December 29, 2025 – In a strategic move aimed at bolstering its financial and operational leadership, 374Water Inc. (NASDAQ: SCWO) today announced the appointment of seasoned finance executive Charles Weiser to its Board of Directors. The appointment, effective immediately, comes as the environmental technology firm navigates a critical phase of commercializing its innovative waste destruction technology. However, the market responded with skepticism, as the company's stock fell 19.6% to $1.90 on the day of the announcement, reflecting the complex challenges facing the growth-stage company.

A Strategic Move at a Pivotal Moment

374Water is at a crucial juncture, balancing promising technological advancements with the harsh realities of financial performance. The company is focused on scaling its core product, the AirSCWO system, which uses supercritical water oxidation to destroy a wide range of organic wastes, including persistent “forever chemicals” like PFAS. Weiser’s appointment is intended to provide the financial stewardship necessary to translate recent operational wins into sustainable growth.

Just days before this announcement, on December 26, the company unveiled a significant partnership with the Cedar Rapids Water Pollution Control Facility in Iowa to deploy its technology for destroying PFAS-laden biosolids. This followed other recent contract wins, including a project in Minnesota also targeting PFAS destruction. These projects signal market traction for 374Water's solution to a pressing environmental problem. Yet, this progress is set against a backdrop of continued financial losses and a recent 1-for-10 reverse stock split, common but often unsettling moves for microcap companies striving for stability.

Stephen J. Jones, Chairperson and Interim President and CEO of 374Water, emphasized the strategic importance of the new board member. “His significant financial expertise and senior management background across a portfolio of growth companies will be instrumental in supporting 374Water’s evolution as we continue to focus on commercialization of our AirSCWO technology and building our Waste Destruction Services business,” Jones stated. He added that the appointment is designed to position the company’s governance for its “next phase of our commercialization initiatives.”

The Weiser File: A Record of Financial Leadership

Charles Weiser brings a formidable resume to the 374Water board. A Certified Public Accountant (CPA) in Texas and Florida, he holds an MBA in Finance and Accounting from the University of Texas, Austin. His career spans decades and includes leadership roles in both public and private enterprises, giving him a deep understanding of the financial mechanics required to scale a business.

Currently the Chief Financial Officer of Alonti Catering Kitchens, Weiser oversees the full spectrum of financial operations, from accounting to strategic planning. His prior experience includes serving as Managing Director at Imperial-Texas, where he provided high-level accounting and consulting services to a global portfolio of businesses. Perhaps most relevant to 374Water's ambitions is his tenure as Executive Vice President and CFO at American Green Technology, a manufacturer and distributor of lighting products for global commercial and industrial sectors. This role provided him with direct experience in managing the finances of a company with complex manufacturing and international distribution challenges—hurdles 374Water will face as it expands.

His expertise in strategic planning, business development, and corporate turnarounds is expected to be a critical asset. For a company like 374Water, which is transitioning from research and development to full-scale commercial deployment, having a director with a proven track record of navigating financial complexities and driving growth is a significant advantage.

From Investor to Insider: A Unique Alignment

The appointment is notable not just for Weiser's professional background, but also for his personal history with the company. In the official announcement, Weiser revealed a long-standing commitment to the firm's mission and potential. “My family, friends, and I have been long time investors in 374Water, since before its listing on NASDAQ in 2022,” he said. “I’m looking forward to working with the Board and Management to support the Company on behalf of all of our shareholders.”

This unique position as a long-term investor turned board member suggests a deep-seated belief in the company's technology and a strong alignment with the interests of other shareholders. The press release also noted the appointment was made “in connection with our working agreement with our largest shareholder.” While the identity of this shareholder was not disclosed, the statement points to a concerted effort by major stakeholders to fortify the company's governance and strategic direction. Bringing Weiser into the boardroom appears to be a direct result of this collaboration, aimed at ensuring that the company's leadership is fully equipped to execute on its long-term value creation strategy.

Navigating a Competitive Environmental Tech Market

374Water operates in the highly competitive and capital-intensive environmental technology sector. Its AirSCWO technology offers a powerful alternative to traditional waste management methods like incineration, which can be energy-intensive and may not fully eliminate hazardous compounds like PFAS. By using water in a supercritical state—a phase where it acts as a powerful solvent—the AirSCWO process can break down complex organic molecules into simple, safe outputs like clean water, inert minerals, and recoverable energy.

The recent project awards in Iowa and Minnesota underscore the growing demand for effective PFAS destruction technologies as regulatory pressure mounts. However, 374Water is not alone. It faces competition from other advanced oxidation process providers and established waste management giants. Successfully scaling its Waste Destruction Services and equipment sales will require not only superior technology but also impeccable financial management, strategic pricing, and the ability to secure large-scale municipal and industrial contracts.

This is precisely where Weiser’s influence could be most profound. His financial acumen will be vital in managing cash flow, securing future funding, and developing a business model that balances innovation with profitability. The challenge for the newly reinforced board will be to convince a wary market that its strategic appointments and technological wins can overcome current financial headwinds and establish 374Water as a leader in solving some of the world's most difficult waste challenges.
