  38. Consideration of Director Nominees

    Consideration of Director Nominees Director Qualifications There are no specific minimum qualifications that the Board requires to be met by a director nominee recommended for a position on our Board, nor are there any specific qualities or skills that are necessary for one or more members of our Board to possess, other than as are necessary to meet the requirements of the rules and regulations applicable to us. The Nominating and Corporate Governance Committee considers a potential director candidate’s experience, areas of expertise and other factors relative to the overall composition of our Board and its committees, including the following characteristics: experience, judgment, commitment (including having sufficient time to devote to the Company), skills, diversity and expertise appropriate for the Company. In assessing potential directors, the Nominating and Corporate Governance Committee may consider the current needs of the Board and the Company to maintain a balance of knowledge, experience and capability in various areas. Stockholder Nominations The Nominating and Corporate Governance Committee will consider director candidates recommended by our stockholders. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the criteria set forth above, based on whether a candidate was recommended by a stockholder or not. Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board at an annual meeting of stockholders must do so by delivering a written recommendation to the Nominating and Corporate Governance Committee, c/o Gevo, Inc., 345 Inverness Drive South, Building C, Suite 310, Englewood, Colorado 80112, Attn: Corporate Secretary, by the time period set forth in our Bylaws. See “Stockholder Proposals and Director Nominations.” Each written recommendation must set forth, among other information as set forth in our Bylaws: • the name and address of the stockholder of record and any beneficial owner on whose behalf the nomination is being made; • the class, series and number of shares of common stock of the Company, and any convertible securities of the Company, that are beneficially owned by the stockholder of record and any beneficial owner on whose behalf the nomination is being made; • any derivative, swap or other transaction or series of transactions engaged in, directly or indirectly, by such stockholder of record and any beneficial owner on whose behalf the nomination is being made; • any proxy, agreement, arrangement, understanding or relationship pursuant to which such stockholder of record and any beneficial owner on whose behalf the nomination is being made has or shares a right to vote any shares of any class or series of the Company; • any agreement, arrangement, understanding or relationship, including any repurchase or similar so-called “stock borrowing” agreement or arrangement, engaged in, directly or indirectly, by such stockholder of record and any beneficial owner on whose behalf the nomination is being made; • a representation that such stockholder of record is a holder of record of stock of the Company entitled to vote at the meeting and intends to appear in person or by proxy at the meeting to nominate such proposed director; • the proposed director candidate’s name, age, business address and residential address; • complete biographical information for the proposed director candidate, including the proposed director candidate’s principal occupation or employment and business experience for at least the previous five years; • the class and number of shares of common stock of the Company that are beneficially owned by the proposed director candidate and any convertible securities of the Company that are beneficially owned by the director candidate as of the date of the written recommendation; a description of all direct and indirect compensation and other material monetary agreements, arrangements and understandings during the past three years, and any other material relationships, between or among any such nominating stockholder, on the one hand, and each proposed nominee, his or her respective affiliates and associates and any other persons with whom such proposed nominee (or any of his or her respective affiliates and associates) is Acting in Concert (as defined in the Bylaws), on the other hand, including, without limitation, all information that would be required to be disclosed pursuant to Item 404 under Regulation S-K if such nominating stockholder were the “registrant” for purposes of such rule and the proposed nominee were a director or executive officer of such registrant; • a completed and signed questionnaire, representation and agreement from the director candidate, as further described in our Bylaws; and • any other information relating to the proposed director candidate that is required to be disclosed in solicitations for proxies for election of directors pursuant to Regulation 14A promulgated under the Exchange Act.

Evaluating Nominees for Director

  39. Consideration of Director Nominees

    Our Nominating and Corporate Governance Committee considers director candidates that are suggested by members of the committee, other members of our Board, members of management, advisors and our stockholders who submit recommendations in accordance with the requirements set forth in our Bylaws, as described above. Our Board has in the past engaged a third-party search firm to identify potential candidates for consideration by the Nominating and Governance Committee and election to our Board. The Nominating and Corporate Governance Committee may, in the future, retain third-party search firms to identify Board candidates on terms and conditions acceptable to the Nominating and Corporate Governance Committee to assist in the process of identifying or evaluating director candidates. The Nominating and Corporate Governance Committee evaluates all nominees for director using the same approach whether they are recommended by stockholders or other sources. The Nominating and Corporate Governance Committee reviews candidates for director nominees in the context of the current composition of our Board and committees, the operating requirements of the Company and the long-term interests of our stockholders. In conducting this assessment, the Nominating and Corporate Governance Committee considers the director nominee’s qualifications, diversity, skills and such other factors as it deems appropriate given the current needs of the Board, the committees and the Company, to maintain a balance of knowledge, experience, diversity and capability. In the case of incumbent directors whose terms of office are set to expire, the Nominating and Corporate Governance Committee reviews such directors’ overall service to the Board, the committees and the Company during their term, including the number of meetings attended, level of participation, quality of performance and any other relationships and transactions that might impair such directors’ independence. In the case of new director candidates, the Nominating and Corporate Governance Committee will also determine whether the nominee must be independent for Nasdaq purposes, which determination will be based upon applicable Nasdaq listing standards and applicable SEC rules and regulations. Although we do not have a formal diversity policy, when considering diversity in evaluating director nominees, the Nominating and Corporate Governance Committee focuses on whether the nominees can contribute varied perspectives, skills, experiences and expertise to the Board. The Nominating and Corporate Governance Committee will evaluate the proposed director’s candidacy, including proposed candidates recommended by stockholders, and recommend whether the Board should nominate the proposed director candidate for election by our stockholders.

  40. Non-Employee Director Compensation Policy

    Non-Employee Director Compensation Policy Consistent with the previous year and the recommendation by our independent compensation consultant, our Board compensation policy provides for the following compensation to our non-employee directors: Annual Equity Grant. Each non-employee director receives an annual equity grant under the Gevo, Inc. Amended and Restated 2010 Stock Incentive Plan (the “2010 Plan”) in an amount valued at $125,000, subject to approval by the Compensation Committee. The annual equity grants vest on the first anniversary of the grant date. Annual Cash Retainers. Each non-employee member of our Board receives an annual cash retainer of $85,000, which is paid in arrears. The Chairman receives an additional annual cash retainer of $25,000; the Chair of the Audit Committee receives an additional annual cash retainer of $15,000; the Chair of the Compensation Committee receives an additional annual cash retainer of $15,000; and the Chair of the Nominating and Corporate Governance Committee receives an additional cash retainer of $10,000. Each member of a committee of the Board (other than the Chairs of such committees) receives an additional cash retainer of $5,000 for each committee they participate on. Effective after the Annual Meeting, upon recommendation by our compensation consultant after review of peer and market data, and approval by the Compensation Committee, the annual cash retainer for the Chairman will be increased to $50,000 and the annual cash retainer for the Chair for the Audit Committee will increase to $20,000. The Compensation Committee periodically reviews the compensation paid to non-employee directors to ensure that the compensation aligns the directors’ interests with the long-term interests of the stockholders. The Compensation Committee also considers whether the compensation paid to non-employee directors fairly compensates the Company’s directors when considering the work required in a company of the size and type of the Company. In addition, the Compensation Committee considers other relevant factors, including periodic independent market assessments, director recruitment considerations and peer group compensation for non-employee directors to determine whether the Company’s non-employee director compensation is reasonable and competitive. Each non-employee director is also reimbursed for reasonable travel and other expenses in connection with attending meetings of the Board and any committee on which he or she serves. We do not compensate Mr. Gruber, our Chief Executive Officer, for his service on the Board.

  50. Executive Compensation Philosophy and Objectives

    Executive Compensation Philosophy and Objectives Our primary objective with respect to executive compensation is to attract, retain and motivate superior executive talent with the skills and experience to successfully execute our business strategy. Our executive compensation program is designed to: • provide short-term competitive incentives that reward the achievement of critical goals that directly correlate to long-term strategy fulfillment and the enhancement of stockholder value; • align the interests of our executives with those of our stockholders by utilizing long-term equity incentives that reward performance through success of the corporation, with the ultimate objective of increasing long-term stockholder value; • provide long-term incentives that promote executive retention; and • align our executives with the long-term strategic goals and objectives approved by our Board. To achieve these objectives, our executive compensation program ties a significant portion of each named executive officer’s cash compensation to key corporate financial and strategic goals. We have also historically provided a portion of our executive compensation in the form of equity awards that vest over time, which we believe helps to retain our named executive officers and aligns their interests with those of our stockholders by allowing them to participate in our long-term performance as reflected in the trading price of our common stock. Role of Compensation Committee, Management and Compensation Consultant Our Compensation Committee makes all compensation decisions regarding our named executive officers. Our Compensation Committee is charged with, among other things, the responsibility of reviewing our named executive officer compensation policies and practices. Our Chief Executive Officer annually reviews the performance of each of our named executive officers, other than himself, and, based on these reviews, makes recommendations to our Compensation Committee regarding salary adjustments, annual incentive bonus payments and equity incentive awards for such named executive officers. The Compensation Committee believes it is valuable to consider the recommendations of our Chief Executive Officer with respect to these matters because, given his knowledge of our operations and the day-to-day responsibilities of our named executive officers, he is in a unique position to provide the Compensation Committee with perspective into the performance of our executive officers in light of our business at a given point in time. While the Compensation Committee considers the Chief Executive Officer’s reviews and recommendations, the Compensation Committee decides the compensation of our named executive officers and also considers, among other things, company and individual performance, peer group data and recommendations from the Compensation Committee’s independent compensation consultant, as further described below. As part of the 2023 compensation process, our Compensation Committee retained Aon’s Human Capital Solutions Practice, a division of Aon plc (“Aon”) as its independent compensation consultant. Aon served in this capacity from March 2021 until August 2023. Aon provided advisory services with respect to executive and equity compensation as directed by the Compensation Committee. From time to time, Aon provided additional services to management in the areas of non-executive compensation, with all such services being approved by the chair of the Compensation Committee before any services were provided. Prior to engaging Aon, our Compensation Committee considered the independence of Aon in accordance with the applicable regulations mandated by Nasdaq and the SEC. After conducting this assessment, our Compensation Committee did not identify any conflicts of interest with respect to Aon. Beginning in August 2023, the Compensation Committee retained Frederic W. Cook & Co., Inc. (“FW Cook”) as its independent compensation consultant. Prior to engaging FW Cook, our Compensation Committee considered the independence of FW Cook in accordance with the applicable regulations mandated by Nasdaq and the SEC. After conducting this assessment, our Compensation Committee did not identify any conflicts of interest with respect to FW Cook. The Compensation Committee took the results of Aon’s comparative analyses of our peer group (as described below), as well as the considerations provided by Aon with respect to components and levels of compensation for our named executive officers, under advisement in determining competitive market practice in our industry. The Compensation Committee considered the assessment of peer group market compensation, historical compensation levels, subjective assessments of individual performance and worth and other subjective factors in establishing and approving the various elements of our executive compensation program for 2023. After considering the data and information provided by Aon, the Compensation Committee made its own determinations about the compensation granted in 2023 to our Chief Executive Officer, our other named executive officers and our non-employee directors. Peer Group Our Compensation Committee has identified certain peer group data with the assistance of Aon. Our peer companies are selected from publicly-traded companies based in the U.S. in similar or adjacent industries and then further refined to more closely align with us based on revenue, market capitalization, employee headcount, and competition for executive talent. The Compensation Committee also takes into consideration our stage of development, net income (loss), other key financial metrics, and the lack of many direct peers in our industry and competitors for talent. At the time the peer group was approved by the Compensation Committee, our market capitalization was positioned at approximately the 31st percentile of our peer group, and our annual revenue was positioned at approximately the 18th percentile of our peer group. The Compensation Committee believes that the companies selected to our peer group are broadly comparable to us and represent our labor market for talent for key leadership positions. Our Compensation Committee reviews our peer group annually to determine if adjustments are necessary to ensure that it continues to be relevant or if additional peer companies or groups are necessary to provide appropriate information on market practices and compensation levels. The Compensation Committee, based on analysis and recommendations from Aon, approved our peer group in March 2023.

  52. Annual Cash Incentives

    Annual Cash Incentives The Compensation Committee believes that annual incentive bonuses that are awarded to our named executive officers based on Company and individual performance goals provide our named executive officers additional incentive to outperform our financial goals, increase stockholder value and ensure that we attract and retain talented named executive officers. Each year, the Compensation Committee establishes a target annual incentive award for each named executive officer expressed as a percentage of the executive’s base salary, based on various factors, including the results of Aon’s comparative assessment regarding annual incentive award targets for comparable positions at peer companies, the estimated contribution and responsibility of the individual named executive officer and market practices. For 2023, the targets for our named executive officers and actual payouts were as follows:

  53. Annual Cash Incentives

    | Named Executive Officer | 2023 Annual Incentive Target (As a Percentage of Base Salary) | Actual 2023 Annual Incentive Payment (As a Percentage of Base Salary) | | Patrick R. Gruber | 100% | 100% | | L. Lynn Smull | 65% | 65% | | Christopher M. Ryan | 80% | 80% | | Paul D. Bloom | 80% | 80% | | Kimberly T. Bowron | 65% | 65% | | Timothy J. Cesarek(1) | 65% | —% |

  54. Annual Cash Incentives

    (1) Our Compensation Committee, at their discretion, assesses the achievement of corporate and individual goals and performance at the end of each fiscal year to determine the appropriate bonus for each named executive officer. The Compensation Committee approved the annual incentive bonuses at 100% of target amounts based on the following factors:

  55. Annual Cash Incentives

    | 2023 Goal and Related Achievements | Target Bonus Percentage | Performance Modifier | Bonus Payment Percentage | | Renewable Natural Gas (“RNG”) injected into the pipeline in an amount greater than 300,000 MMBtu • We injected greater than 300,000 MMBtu into the pipeline. | 15% | 110% | 16.5% | | Manage operating expenses and stay under budget. • We managed to keep our operating expenses under the budgeted amount for 2023. | 10% | 150% | 15.0% | | Enter into a licensing deal for, and continue development of, our ethanol-to-olefins (“ETO”) technology. • We entered into a joint development agreement with LG Chem, Ltd. and received initial payments under the agreement in 2023. | 15% | 150% | 22.5% | | Verity meets certain operational goals by December 31, 2023 • We provided a prototype of our Verity biofuel producer tool to one of our customers. • We signed agreements with three biofuels customers for Verity. | 20% | 100% | 20.0% | | Extend the licensing agreement with Axens North America, Inc. for two years. • The Master Framework Agreement with Axens North America, Inc. was extended into 2024 but didn’t meet all of the conditions necessary to satisfy the goal. | 10% | —% | —% | | Continue to progress the Net-Zero Projects. • We entered into the due diligence and term sheet negotiation phase for a $950 million loan guarantee from the Department of Energy. • Advanced project engineering with our EPC partners. • Substantially completed negotiation of our EPC agreements. | 30% | 87% | 26.0% | | Total | 100% | | 100% |

  56. Annual Cash Incentives

    In addition, as noted above, in May 2023, the Compensation Committee awarded the Special Net-Zero 1 Bonus due to significant progress by the Company in achieving financial close for the Net-Zero 1 project. The Special Net-Zero 1 Bonus was equal to a 50% attainment of our prior 2022 goal for the financial close of the Net-Zero 1 project.

  57. Equity Incentive Awards

    Equity Incentive Awards We believe that our long-term performance is enhanced through equity awards to our named executive officers. Equity awards are designed to reward our named executive officers for maximizing stockholder value over time, retain the services of our named executive officers, ensure focus on long-term value creation and our strategic objectives and align the long-term interests of our named executive officers with those of our stockholders. All equity incentive awards granted to our named executive officers are approved by our Compensation Committee. Equity incentive awards to our named executive officers and other direct reports of the chief executive officer are made in the form of premium-priced stock options with exercise prices at a premium to the closing market price of our common stock on the date of grant and time-vesting restricted stock awards, each of which vest in three equal installments on the first three anniversaries of the grant date. In 2023, we added a one-year minimum vesting period to the 2010 Plan, subject to an allowable pool of up to five percent (5%) of the number of shares authorized for issuance under the plan that may be granted without regard to the one-year minimum vesting requirement. We believe that equity incentive awards: • provide our named executive officers with a strong link to our long-term performance by enhancing their accountability for long-term decision making. Since stock options realize value only through stock price appreciation, the value realized upon the exercise of vested stock options directly aligns the compensation earned with the value stockholders receive over the same period; • create an ownership culture by aligning the interests of our named executive officers with the creation of long-term value for our stockholders; and • further our goal of executive retention. The equity awards granted to our named executive officers in 2023 were as follows:

  58. Equity Incentive Awards

    | Named Executive Officer | Premium-Priced Stock Options (#)(1) | Restricted Stock (#)(1) | | Patrick R. Gruber | 742,924 | 742,924 | | L. Lynn Smull | 207,222 | 207,222 | | Christopher M. Ryan | 266,220 | 266,220 | | Paul D. Bloom | 207,222 | 207,222 | | Kimberly T. Bowron | 85,499 | 85,499 | | Timothy J. Cesarek(2) | 207,222 | 207,222 |

  59. Equity Incentive Awards

    (1) Premium-priced stock options and restricted stock awards vest in three equal installments on the first three anniversaries of the grant date. (2) Mr. Cesarek resigned from the Company on September 22, 2023 and forfeited his unvested equity awards. In 2023, the Compensation Committee granted our named executive officers an equity mix of 50% premium-priced stock options and 50% restricted stock that vest in three equal installments on the first three anniversaries of the grant date. The premium-priced stock options granted in 2023 have a strike price that is approximately 10% greater than the closing price of our common stock on the date of grant. The Compensation Committee sets targets for annual equity compensation for each of the executive officers. The targets are informed by a survey of our peer group’s and similar companies’ pay practices. The Compensation Committee does not target a specific percentile ranking against our peer group and may grant long-term incentive awards at the higher end of the range for a variety of factors, including individual performance, but typically targets the 50th percentile for base salaries and bonuses and targets the 50th percentile for equity compensation. The actual grant date value of equity compensation awarded is individually determined at the discretion of the Compensation Committee. Consideration is given to the individual’s skills, experience and future potential to positively impact the Company’s performance, prior years’ award values, equity ownership level in the Company, as well as the individual’s and Company’s performance in the prior year. The ultimate value of equity grants is dependent on our stock price on the date of exercise and reflects the Compensation Committee’s attempt to further incent and align the long-term interests of our executives with those of our stockholders, while providing a strong retention tool. We consider premium-priced stock option grants to our named executive officers as performance-based since they have an exercise price equal to the closing price of our stock on the grant date plus a premium, which was an approximately 10% premium over the closing price of our stock on the date of grant in 2023. One third of the option shares and restricted stock awards vest on the first anniversary of the grant date, with the remaining option shares and restricted stock awards vesting in annual installments over the subsequent two years, provided that the named executive officer remains in continuous service with us as of each vesting date. The premium-priced stock options granted in 2023 require the stock price to stay at or above the strike price for such option for at least 20 consecutive trading days (or 30 calendar days) before the stock option can be exercised by the grantee. Other Compensation Policies and Practices

  60. Severance and Change in Control Arrangements

    Severance and Change in Control Arrangements We have entered into employment agreements with certain of our named executive officers. Each of these agreements provides the applicable named executive officer with certain severance benefits in connection with certain terminations of the executive’s employment both before and after a change in control. During 2022, the Compensation Committee approved and adopted the Gevo, Inc. Change in Control Severance Plan (the “CIC Plan”) for eligible employees of the Company. The participants in the CIC Plan include certain of the Company’s executive officers that do not have employment agreements with the Company and certain other members of the Company’s senior management. The CIC Plan provides the applicable participant with certain severance benefits in connection with a double-trigger change in control (i.e., termination of the executive’s employment by the Company without Cause (as defined in the CIC Plan) or the executive’s resignation from the Company for Good Reason (as defined in the CIC Plan) within 30 days prior to or 12 months following the Change in Control (as defined in the CIC Plan)). The Compensation Committee believes that reasonable severance and change in control protections for the named executive officers strengthens our competitive compensation package by providing us with a recruitment and retention benefit, aligns the interests of the named executive officers with those of the stockholders and ensures continued dedication to the Company in change in control situations that may result in personal uncertainties.

  61. Accounting Considerations

    Accounting Considerations ASC Topic 718, Compensation - Stock Compensation (referred to as ASC Topic 718), requires us to recognize an expense for the fair value of equity-based compensation awards. Grants of stock options and restricted stock under our equity incentive award plans will be accounted for under ASC Topic 718. We will consider the accounting implications of significant compensation decisions, especially in connection with decisions that relate to our equity incentive award plans and programs. As accounting standards change, we may revise certain programs to appropriately align accounting expenses of our equity awards with our overall executive compensation philosophy and objectives.

Messrs.

  83. CEO Pay Ratio

    CEO Pay Ratio As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of SEC Regulation S-K, we are providing the following information about the relationship of the annual total compensation of Patrick R. Gruber, our Chief Executive Officer, and the annual total compensation of our “Median Employee”. For 2023, our last completed fiscal year: • the annual total compensation of our Chief Executive Officer was $3,746,158; and • the annual total compensation of our Median Employee was $165,000. Based on this information, for 2023 the ratio of the annual total compensation of our Chief Executive Officer to the Median Employee was 22 to 1. This ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of SEC Regulation S-K. We used the following material assumptions, adjustments and estimates to identify the Median Employee and to determine the annual total compensation of our Chief Executive Officer and the Median Employee: • We determined that, as of December 31, 2023, our employee population consisted of approximately 95 individuals (excluding the Chief Executive Officer) who were working at the Company and its consolidated subsidiaries. This population consisted of our full-time, part-time and temporary employees. • To identify the Median Employee from our employee population (excluding the Chief Executive Officer), we first determined each employee’s base salary as of December 31, 2023. For any employees that were employed for less than the full fiscal year, we annualized their base salary for the full fiscal year. Then we determined the overtime earnings and annual cash bonus paid during fiscal year 2023 as reflected in our payroll records, and the grant value of restricted stock and stock options granted during fiscal year 2023. Then we identified our Median Employee from our employee population based on this compensation measure. • In accordance with the SEC rules, we determined the Chief Executive Officer’s 2023 annual total compensation to be equal to $3,746,158, which represents the amount reported for fiscal year 2023 for our Chief Executive Officer in the “Total” column of our “Summary Compensation Table” above. • In accordance with the SEC rules, we determined the Median Employee’s 2023 total annual compensation to be equal to $165,000, which represents the amount of such employee’s compensation for fiscal year 2023 that would have been reported in our “Summary Compensation Table” in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K if the employee had been a named executive officer for fiscal year 2023.

  84. Pay Versus Performance

    Pay Versus Performance As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive compensation and certain financial performance of our Company. The disclosure included in this section is prescribed by SEC rules and does not necessarily align with how the Company or the Compensation Committee views the link between the Company’s performance and the compensation of the Company’s named executive officers. The table below presents information on the compensation of our principal executive officer (“PEO”) and our non-PEO named executive officers (“NEOs”) in comparison to certain performance metrics for 2023, 2022 and 2021. The metrics are not those that the Compensation Committee uses when setting executive compensation. The use of the term “compensation actually paid” is required by the SEC’s rules. Neither compensation actually paid nor the total amount reported in the 2023 Summary Compensation Table above reflect the amount of compensation actually paid, earned or received during the applicable year.

    The PEO for 2023, 2022 and 2021 is Mr. Gruber. The Non-PEO NEOs for whom the average compensation is presented in this table for 2022 and 2021 are Messrs. Smull, Ryan, Cesarek and Bloom. The Non-PEO NEOs for whom the average compensation is presented in this table for 2023 are Messrs. Smull, Ryan, Cesarek and Bloom and Ms. Bowron. (2) Compensation Actually Paid reflects the exclusions and inclusions of certain amounts for the PEO and the Non-PEO NEOs as set forth below. Equity values are calculated in accordance with FASB ASC Topic 718, and the valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant.

  89. Pay Versus Performance

    In accordance with Item 402(v) of Regulation S-K, we are providing the following graphical descriptions of the relationships between information presented in the Pay Versus Performance table on compensation actually paid and each of total shareholder return (“TSR”) or net income (loss). We do not utilize TSR and net income (loss) in our executive compensation program. As described in more detail above in the section “Compensation Discussion and Analysis,” part of the compensation our named executive officers are eligible to receive consists of annual cash bonuses that are designed to provide appropriate incentives to our executives to achieve defined annual corporate goals and to reward our executives for achievement towards these goals. Additionally, we view premium-priced stock options, which are part of our executive compensation program, as related to company performance although not directly tied to TSR, because they provide value only if the market price of our common stock increases, and if the executive officer continues in our employment over the vesting period. These stock option awards intend to align our executive officers’ interests with those of our stockholders by providing a continuing financial incentive to maximize long-term value for our stockholders and by encouraging our executive officers to continue in our employment for the long-term.

  91. Compensation Actually Paid vs. Company Net Income (Loss)

    Compensation Actually Paid vs. Company Net Income (Loss) The following table sets forth information about the beneficial ownership of our common stock as of March 25, 2024 by: • each person, or group of affiliated persons, known to us to be the beneficial owner of more than 5% of our common stock; • each named executive officer and each director; and • all of our executive officers and directors as a group. Unless otherwise noted below, the address of each beneficial owner listed in the table is c/o Gevo, Inc., 345 Inverness Drive South, Building C, Suite 310, Englewood, Colorado 80112. We have determined beneficial ownership in accordance with the rules of the SEC. Except as indicated by the footnotes below, we believe, based on the information furnished to us, that the persons and entities named in the tables below have sole voting and investment power with respect to all shares of common stock that they beneficially own, subject to applicable community property laws. This table is based upon information supplied by our officers, directors and the Schedules 13D and 13G that have been filed with the SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose. Under such rules, beneficial ownership includes any shares as to which the individual or entity has sole or shared voting power or investment power and any shares as to which the individual or entity has the right to acquire beneficial ownership within 60 days of March 25, 2024 through the exercise of any stock option or SAR. The inclusion of such shares, however, does not constitute an admission that the named stockholder is a direct or indirect beneficial owner of, or receives the economic benefit from, such shares and we did not deem these shares outstanding for the purpose of computing the percentage ownership of any other person. All unvested restricted stock awards are included in each holder’s beneficial ownership as holders are entitled to voting rights upon issuance of the restricted stock awards. Applicable percentages are based on 241,778,266 shares of common stock outstanding on March 25, 2024.

  99. Indemnification Agreements with Directors and Executive Officers

    Indemnification Agreements with Directors and Executive Officers We have entered into indemnification agreements with our directors and executive officers under which we agreed to indemnify those individuals under the circumstances and to the extent provided for in the agreements, for expenses, damages, judgments, fines, settlements and any other amounts they may be required to pay in actions, suits or proceedings which they are or may be made a party or threatened to be made a party by reason of their position as a director, officer or other agent of ours, and otherwise to the fullest extent permitted under Delaware law and our Bylaws. We also have an insurance policy covering our directors and executive officers with respect to certain liabilities, including liabilities arising under the Securities Act or otherwise. We believe that these provisions and insurance coverage are necessary to attract and retain qualified directors, officers and other key employees.

    | HOUSEHOLDING OF PROXY MATERIALS |

  101. Indemnification Agreements with Directors and Executive Officers

    The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy materials with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies. This year, a number of brokers with account holders who are the Company’s stockholders may be “householding” our proxy materials. A single copy of the proxy materials may be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be householding communications to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate copy of the proxy materials, please (1) notify your broker, (2) direct your written request to Gevo, Inc., c/o Corporate Secretary, 345 Inverness Drive South, Building C, Suite 310, Englewood, Colorado 80112 or (3) call Investor Relations at (303) 858-8358. Stockholders who currently receive multiple copies of the proxy materials at their address and would like to request householding of their communications should contact their brokers. In addition, upon written or oral request to the address or telephone number set forth above, we will promptly deliver a separate copy of the proxy materials to any stockholder at a shared address to which a single copy of the documents was delivered.

All proposals should be directed to our Corporate Secretary, at 345 Inverness Drive South, Building C, Suite 310, Englewood, Colorado 80112. Pursuant to the terms of our Bylaws, stockholders wishing to submit proposals or director nominations for consideration at our 2025 Annual Meeting of Stockholders, including those that are not to be included in such proxy statement and proxy, must provide timely notice in writing to our Corporate Secretary, at 345 Inverness Drive South, Building C, Suite 310, Englewood, Colorado 80112.
