FOR IMMEDIATE RELEASE

Gevo Announces Appointment of Todd Werpy to

Board of Directors

ENGLEWOOD,

Colo. – July 16, 2026 – Gevo, Inc. (NASDAQ: GEVO), a leader in renewable fuels, chemicals and carbon

management, today announced the appointment of Todd Werpy, Ph.D. to its Board of Directors. Werpy brings more than three decades of innovation

and executive leadership experience spanning sustainable technologies, global research and development, manufacturing operations, and

“Todd is a highly respected leader whose unique combination of

scientific expertise, operational discipline and commercial execution will be a tremendous asset to Gevo,” said Gevo Chief

and sustainable growth, we believe Todd’s experience scaling technology, modernizing operations and transforming complex manufacturing

organizations will strengthen our Board and help guide Gevo’s next phase of value creation.”

A recognized scientist, innovator and business leader, Werpy most

recently served as Chief Science Officer and a member of the Executive Committee at Archer-Daniels-Midland Company (ADM) where he helped build a strong technology pipeline that generated significant enterprise value through innovation, commercialization

and strategic partnerships. He also was an executive leader supporting modernization programs involving automation, advanced process controls

and analytics that delivered significant returns while improving productivity, reliability, and sustainability. His expertise spans biotechnology,

catalysis, process engineering and commercialization of bio-based technologies.

“Gevo has built a strong foundation of technologies, assets and

capabilities that can help address some of the most important challenges facing markets today,” said Werpy. “I am honored

to join the Board and look forward to working alongside my fellow directors and the management team to support Gevo’s continued

growth and long-term success.”

Werpy holds a Ph.D. in Inorganic Chemistry from Michigan State University

and is a graduate of the Harvard Business School Executive Leadership Program. He holds 36 U.S. patents and more than 100 patents globally

and is the recipient of the American Chemical Society’s Green Chemistry Award. He is also widely recognized as a co-author of the

U.S. Department of Energy report, Top 12 Value-Added Chemicals from Biomass.

The addition of Todd Werpy to the Gevo Board of Directors is effective
