OPAL Fuels Announces Appointment of Scott M. Sutton to its Board of Directors

WHITE PLAINS, N.Y. – (DATE TBD) – OPAL Fuels (Nasdaq: OPAL) a leader in the production, marketing, and distribution of renewable and compressed natural gas (RNG and CNG) used as a transportation fuel for heavy-duty trucking, today announced the appointment of Scott M. Sutton to its Board of Directors, effective November 1, 2025.

OPAL Fuels’ vertically integrated model combines upstream RNG production with downstream fueling infrastructure that delivers a scalable, lower-cost and emission diesel alternative for the heavy-duty transportation sector. While RNG and CNG currently account for roughly 2% of the market, OPAL Fuels’ business directly targets this significant growth opportunity within a large and expanding addressable market.

With major fleet operators increasingly ready to adopt RNG/CNG as a transportation fuel, OPAL Fuels is positioned to meet this emerging demand. Supported by a robust project pipeline, the company is pursuing growth opportunities as it enhances its operational platform to capitalize on its business model and the growing adoption of RNG/CNG.

Mr. Sutton’s appointment to the OPAL Fuels Board of Directors brings deep expertise in operational excellence that will support OPAL Fuels to build a best-in-class operational platform in order to drive execution of the company’s growth strategy. Mr. Sutton is a seasoned executive with more than 30 years of leadership in the chemicals industry. In his most recent role as Chairman, CEO, and President of Olin Corporation, Mr. Sutton lifted EBITDA from $600MM/yr to $2.5B/yr in 18 months, which increased public equity value by 500%. Throughout his previous roles, President and Chief Executive Officer of Prince International Corporation and Chief Operating Officer of Celanese Corporation, Mr. Sutton was able to drive robust EBITDA performance, reflecting an ability to achieve long-term growth and shareholder value.

“RNG and CNG are proven, scalable, and cost-effective solutions that can transform heavy-duty transportation today,” said Mr. Sutton. “I am excited to join the OPAL Fuels Board and contribute my experience in operational excellence to help strengthen the company’s impact in this critical market.”

“We are thrilled to welcome Scott to our Board, whose deep expertise and leadership experience will help OPAL Fuels further scale its platform and capture the significant opportunities ahead,” said Mark Comora, Chairman of OPAL Fuels’ Board of Directors. “This addition further enhances our ability to deliver strong performance, meet our ambitious EBITDA goals, and advance the decarbonization of heavy-duty transportation.”
