DRAFT – NOT FOR RELEASE

Gevo Reports First Quarter 2012 Financial Results

Luverne, Minn. plant retrofit for commercial isobutanol production on schedule

ENGLEWOOD, Colo. — May 1, 2012 — Gevo, Inc. (NASDAQ: GEVO), an innovative renewable chemicals and advanced biofuels company, today announced its financial results for the three months ended March 31, 2012 and updated its expectations for isobutanol commercialization.

“I am pleased to reiterate that we remain on track to start producing renewable isobutanol at our Luverne, Minn. plant by June 30 of this year,” said Dr. Patrick Gruber, Chief Executive Officer. “We are delivering on our most important milestone to date. Consistent with prior guidance, we anticipate the majority of our Luverne production to be shipped to Sasol Chemical Industries, Ltd. under our multi-year off-take agreement. Additionally, our co-produced Isobutanol Distiller’s Grains (iDGs^TM) will be marketed by Land O’Lakes Purina Feed, LLC and we recently expanded our relationship with Land O’Lakes Purina Feed under a JDA to develop value-added feed applications. This is but one example of our focus on deriving value from our entire business system. Our ongoing detailed engineering of the Redfield Energy retrofit in South Dakota is progressing well as we continue to utilize insight gained from Luverne to optimize Redfield’s design.”

“On the intellectual property front, we continue to make excellent progress,” added Gruber. “Building on the foundational patent received in the first quarter covering our GIFT^® separation system, we received three patents this quarter that cover critical technologies that enable increased isobutanol yields from our proprietary yeast. We have now received eight patents over the past eight months. We believe our engineering and yeast patents and patent applications combine to uniquely position Gevo as the leader in producing isobutanol economically and at full commercial scale.”

Recent Corporate Highlights

• Gevo acquired technology developed by AmbroZea, Inc. embodied in U.S. Patent No. 7,309,602 “Compositions and Methods for Producing Fermentation Products and Residuals” and multiple patent applications. The acquired technology is based on modifications to yeast strains that increase the overall value of fermentation by co-producing lucrative nutrients for the animal food chain during fermentations. Gevo believes that, working in conjunction with its partner Land O’Lakes Purina Feed, this technology can be used to further enhance the value of iDGs™.

• Gevo and VP Racing Fuels, Inc. a world leader in race fuel technology with a diverse product catalog of high-quality specialty fuel blends, have agreed to jointly evaluate the commercial potential for

isobutanol in a wide array of markets. The goal is to develop a product line of renewable, high-performance, isobutanol-based fuel blends for the small engine market while looking toward other performance applications for isobutanol as well.

Additional First Quarter Highlights

• Gevo signed an off-take and marketing agreement with Land O’Lakes Purina Feed for the sale of iDGs™ produced at Gevo’s production facility in Luverne. Land O’Lakes Purina Feed will be the exclusive marketer of Gevo’s isobutanol dried and modified wet iDGs™ produced at the Luverne facility for the animal feed market. The companies solidified this relationship with a Joint Development Agreement to explore opportunities for special value-added applications in feed markets.

• Gevo was awarded three patents for the “Reduced By-Product Accumulation for Improved Production of Isobutanol,” including U.S. Patent No. 8,133,715, U.S. Patent No. 8,153,415 and U.S. Patent No. 8,158,404. These patents recognize Gevo’s unique approach to streamlining isobutanol production in yeast. The patents cover technology that eliminates carbohydrate-hijacking pathways and improves the yield of isobutanol production. Gevo strongly believes the modifications covered by these patents are strictly required for achieving commercially relevant production of isobutanol.

• Gevo was awarded U.S. Patent No. 8,101,808, “Recovery of Higher Alcohols From Dilute Aqueous Solutions,” a landmark patent on its GIFT^® separation system which is a central element in Gevo’s unique fermentation technology for the production of isobutanol and addresses how ethanol plants can be retrofitted to produce higher alcohols.

• Gevo was awarded U.S. Patent No. 8,097,440, “Engineered Microorganisms Capable of Producing Target Compounds Under Anaerobic Conditions.” The patent covers a foundational aspect of Gevo’s yeast technology that is designed to enable the low-cost, high-yield production of biobased isobutanol. Gevo believes the most efficient and economical way to make isobutanol through fermentation is to use yeast that is anaerobic, or doesn’t need oxygen. Gevo has been awarded a patent for a novel enzyme for enabling the anaerobic production of isobutanol in yeast.

• Gevo appointed Ruth Dreessen to its Board of Directors. Dreessen, a managing director of Lion Chemical Capital, LLC, has over 32 years of experience in chemicals and related industries. Her track record in investment banking, acquisitions and financing adds critical expertise to Gevo’s Board of Directors.

Financial Highlights

Revenues for the first quarter of 2012 were $14.9 million compared to $15.3 million in the same period in 2011 reflecting an increase in grant and research and development program revenue and a decrease in ethanol sales, primarily resulting from a lower market price of ethanol during the first quarter of 2012. During the ongoing isobutanol retrofit, the Luverne facility has continued to generate revenue from the production and sale of ethanol and related products.

Research and development expense increased to $5.0 million in the first quarter of 2012 from $3.3 million for the same period in 2011. Increased investment in research and development in the first quarter of 2012 reflected increased headcount and stock-based compensation cost as well as other resources deployed in support of the ongoing retrofit of the Luverne facility.

Selling, general and administrative expense for the first quarter of 2012 increased to $13.1 million from $5.2 million for the same period in 2011. Contributing to this increase was $3.0 million in stock-based compensation expense due in part to a one-time $2.6 million non-cash expense resulting from the accelerated vesting of warrants upon the departure of two executive vice presidents. The increase also included legal-related costs including expenses in support of Gevo’s ongoing litigation with Butamax™ Advanced Biofuels, LLC, increased personnel and related expenses to support initial commercialization activities, one-time severance expense related to the departure of the two executive vice presidents and increased compliance activities as a public company.

The net loss for the first quarter of 2012 was $19.3 million compared to $9.3 million for the first quarter of 2011.

During the three months ended March 31, 2012, Gevo continued to make strides towards completing the retrofit of its Luverne plant. The Company incurred $13.3 million in retrofit related capital expenditures during the first quarter of 2012.

Gevo reported cash and cash equivalents on hand of $73.6 million as of March 31, 2012.
