Clean Energy appoints Bart Frabotta as Chief Operating Officer

Newport Beach, Calif. – June 23, 2026 — Clean Energy Fuels Corp. (NASDAQ: CLNE), the country’s leading provider of renewable natural gas (RNG) for the transportation market, today announced the appointment of Bart Frabotta as Chief Operating Officer (COO). Frabotta will oversee Clean Energy’s operations division and will also become one of the company’s named executive officers.

Frabotta joined Clean Energy in 2010 and has served as Group Vice President of Operations since 2021. He has over 20 years of leadership experience in energy infrastructure, construction, operations, technology, and industrial services.

Stepping into the role as COO, he will lead company-wide operational functions, including station operations, RNG and liquefied natural gas (LNG) production, engineering and construction, field services, supply chain, EHS, IT, and AI initiatives. He will also oversee key business transformation programs.

“Since joining Clean Energy, Bart has been tasked with more and more responsibilities and has always overperformed,” said Clay Corbus, President and CEO of Clean Energy. “His leadership has driven meaningful change in reliability, efficiency, and cost structure across our station network. I will look to Bart to take the lead in two of my top priorities – becoming a technology-forward company implementing all the advantages AI has to offer, and making Clean Energy a low-cost company while still accelerating growth.”

“Taking on the role of COO at such an important time for Clean Energy and the broader alternative fuels industry is both an honor and a tremendous opportunity,” said Frabotta. “We have an incredibly talented team across the organization, and I’m excited to continue working alongside them to enhance our capabilities, deliver reliable solutions, and help drive our company into its next phase of growth.”
