Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

The information contained under Item 8.01 is incorporated herein by reference.

Gevo, Inc. (the “Company”) and a large ethanol producer in the Midwest (the “JV Partner”) have entered into advanced negotiations to finalize the definitive documents necessary to commence a joint venture pursuant to a non-binding letter of intent between the parties which was first disclosed in the Registration Statement on Form S-1/A filed by the Company with the Securities and Exchange Commission on January 19, 2011. The transaction contemplates a joint venture between the JV Partner and the Company pursuant to which the JV Partner would make available its existing 50 million gallon per year ethanol production facility and the Company would be responsible for retrofitting such facility to produce isobutanol. Upon completion of the retrofit, both parties to the joint venture would receive a portion of the profits from the sale of isobutanol, consistent with the Company’s business model.

While the Company and the JV Partner have entered into advanced negotiations to finalize the definitive documents necessary to commence the joint venture project there can be no assurance that the Company will reach an agreement on final terms or be successful in executing a definitive joint venture agreement with the JV Partner at any particular time or at all. In the event that a definitive agreement is reached, management will disclose all agreements deemed material through Form 8-K filings in accordance with Securities and Exchange Commission regulations.
