Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On December 30, 2014, Gevo, Inc. (the “Company”) received notice from the Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) that its application to transfer its common stock listing from the Nasdaq Global Market to the Nasdaq Capital Market had been approved. The Company’s common stock listing will transfer to the Nasdaq Capital Market at the opening of trading on January 5, 2015. Following the move to the Nasdaq Capital Market, the Company’s common stock will continue to trade under the symbol “GEVO”.

As the Company previously announced, on June 30, 2014 the Company received notice from Nasdaq that it did not meet the minimum $1.00 per share requirement for continued listing on the NASDAQ Global Market under Marketplace Rule 5450(a)(1). By transferring its common stock listing from the Nasdaq Global Market to the Nasdaq Capital Market, the Company received an additional 180 calendar day compliance period, or until June 29, 2015, to regain compliance with the minimum $1.00 per share requirement for continued listing on the Nasdaq Capital Market. The Company intends to monitor the bid price of its common stock and its minimum market value of listed securities and will consider options available to it to achieve compliance.

Except for the factual statements made herein, information contained in this report consists of forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that involve risks, uncertainties and assumptions that are difficult to predict. Words such as “will,” “believes,” “intends,” “expects,” “plans,” and similar expressions, or the use of future tense, identify forward-looking statements, but their absence does not mean that a statement is not forward-looking. Such forward-looking statements are not guarantees of performance and actual actions or events could differ materially from those contained in such statements. For example, there can be no assurance that the Company will meet the bid price requirement during this compliance period or in the future, or otherwise meet Nasdaq compliance standards, or that Nasdaq will grant the Company any relief from delisting as necessary or that the Company can ultimately meet applicable Nasdaq requirements for any such relief. The forward-looking statements contained in this report speak only as of the date of this report and the Company undertakes no obligation to publicly update any forward-looking statements to reflect changes in information, events or circumstances after the date of this report, unless required by law.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
