Exhibit 99.1

For Immediate Release

Gevo Issues Statement on USPTO Reexamination of U.S. Patent 8,101,808

ENGLEWOOD, Colo. – July 23, 2012 – Gevo, Inc. (NASDAQ: GEVO), a leading renewable chemicals and next-generation biofuels company, issues statement regarding U.S. Patent and Trademark Office (USPTO) announcement to grant the Butamax^TM Advanced Biofuels, LLC (Butamax) Request for Reexamination of Gevo’s GIFT^® technology, U.S. Patent 8,101,808.

“Reexaminations are part of the normal course of a patent dispute, especially when dealing with valuable technology. This reexamination does not validate patent applications of Butamax or anyone else—that isn’t what reexaminations do. The headline in the Butamax press release is inflammatory and misleading.

Gevo’s ‘808 Patent covers multiple production technologies for higher alcohols in retrofitted ethanol plants. We believe that Butamax is infringing at least one of those technologies. While our claims have been set aside in this most recent USPTO action, Gevo’s lawsuit against Butamax for infringing this ‘808 Patent remains unaffected, the trial is scheduled for July of 2014.

The next step in the reexamination process is that we will argue why our claims are valid. We also have the opportunity to modify our claims. Gevo believes it has the earliest priority dates on its key commercially viable technologies—including the process technology and biocatalyst. We also hold several other patent applications covering our GIFT^® technology and continue to lead in biobased isobutanol technology and commercialization.” – Brett Lund, Executive Vice President and General Counsel for Gevo.
