Dear Fellow Stockholder:

We recently mailed proxy materials to you for the Special Meeting of Stockholders of Gevo, Inc. (“Gevo,” “we,” “us or “our”) scheduled to be held on December 14, 2016 to consider and vote upon a proposal to effect a reverse stock split of our outstanding common stock by a ratio of not less than one-for-two and not more than one-for-twenty at the discretion of the Board of Directors.

At the time of the mailing of this reminder letter, our records indicate you may have not yet voted your shares. If you already have voted, we thank you for your prompt response. If you have not voted your shares, the Board of Directors encourages you to submit your vote in favor of the reverse stock split proposal as soon as possible.

Please let us remind you that there are a several ways to vote:


  1. Internet — By logging into the secure website at and following the instructions provided;


  2. Telephone — By calling the toll-free number 1-800-690-6903 on a touch-tone phone and following the recorded instructions; or


  3. Mail — By returning the enclosed proxy card in the provided postage-paid return envelope.

As we have described in the proxy statement for the Special Meeting, approval of the reverse stock split proposal is critical to the ongoing operations of Gevo. The Board of Directors strongly believes that the reverse stock split is necessary for the following reasons:


    Maintain our listing on the NASDAQ Capital Market;


    Provide us the necessary resources and flexibility to raise sufficient capital to execute our business plans and strategy; and


    Improve the marketability and liquidity of our common stock.

For these reasons, and as more fully described in the proxy statement previously distributed to you, the Board of Directors has recommended that you vote “FOR” approval of the reverse stock split proposal.

We need your vote. For your vote to count, you must vote by proxy before, or in person at, the Special Meeting on December 14, 2016. Regardless of how many shares you own, it is important that you vote them as soon as possible.

If you haven’t received your proxy materials and voting instructions, or if you need any assistance in casting your vote, please contact our proxy solicitor.
