 EXPLANATORY NOTE

 This Amendment No. 1 to the Annual Report on Form 10-K (this "Amendment") of LanzaTech Global, Inc. (collectively referred to herein as "the Company", "LanzaTech", "we", "us", "our") amends LanzaTech's Annual Report on Form 10-K for the year ended December 31, 2024 filed with the U.S. Securities and Exchange Commission (the "SEC") on April 15, 2025 (the "Original 10-K"). This Amendment amends Part III, Items 10, 11, 12, 13 and 14 of the Original 10-K in their entirety to include the information required by such Items and to remove references in the Original 10-K to the incorporation by reference of certain information from either a proxy statement or an amendment on Form 10-K into Part III of the Original 10-K. In addition, this Amendment amends Part IV, Item 15 of the Original 10-K to include new certifications by our principal executive officer and principal financial officer under Section 302 of the Sarbanes-Oxley Act of 2002 as required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the "Exchange Act").
 Except as described above, this Amendment does not modify or update in any way the other disclosures or information contained in the Original 10-K. Except as otherwise set forth herein, this Amendment does not reflect events occurring after the filing of the Original 10-K. Accordingly, this Amendment should be read in conjunction with the Original 10-K and LanzaTech's other filings made with the SEC subsequent to the filing of the Original 10-K.

 CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
 This Amendment contains "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Exchange Act, which are subject to the "safe harbor" created by those sections. This includes, without limitation, statements regarding the financial position, business strategy and the plans and objectives of management for future operations. These statements constitute projections, forecasts and forward-looking statements, and are not guarantees of performance. Such statements can be identified by the fact that they do not relate strictly to historical or current facts. When used in this Amendment, words such as "anticipate," "believe," "continue," "could," "estimate," "expect," "intend," "may," "might," "plan," "possible," "potential," "predict," "project," "should," "strive," "would" and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. When we discuss our strategies or plans, we are making projections, forecasts or forward-looking statements.
 Forward-looking statements may include, for example, statements about:
 • our ability to continue operations as a going concern;
 • our ability to achieve profitability;
 • our ability to raise substantial financing to fund our operations and/or execute on our other strategic options;
 • whether the non-binding proposal received on April 3, 2025 from Carbon Direct Capital Management LLC ("Carbon Direct Capital") offering to acquire all of the outstanding shares of our common stock for $0.02 per share (the "Take-Private Proposal"), will result in a definitive transaction;
 • our anticipated growth rate and market opportunities;
 • our ability to maintain the listing of our securities on the Nasdaq Stock Market LLC ("Nasdaq");
 • our ability to attract, retain and motivate qualified personnel;
 • the potential liquidity and trading of our securities;
 • our future financial performance and capital requirements;
 • our assessment of the competitive landscape;
 • our ability to comply with laws and regulations applicable to our business;
 • our ability to enter into, successfully maintain and manage relationships with industry partners;
 • the availability of governmental programs designed to incentivize the production and consumption of low-carbon fuels and carbon capture and utilization;
 • our ability to adequately protect our intellectual property rights;
 • our ability to manage our growth effectively;
 • our ability to increase our revenue from engineering services, sales of equipment packages and sales of CarbonSmart products and to improve our operating results; and
 • our ability to implement and maintain effective internal controls.

 We caution you that the foregoing list may not contain all of the forward-looking statements made in this Amendment.

 These forward-looking statements are based on our current expectations and projections about future events and are subject to a number of risks, uncertainties and assumptions, including those described in Part I, "Item 1A- Risk Factors" and elsewhere in the Original 10-K. Moreover, we operate in a competitive industry, and new risks emerge from time to time. It is not possible for management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this Amendment may not occur, and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements in this Amendment.

 The forward-looking statements included in this Amendment are made only as of the date hereof. You should not rely upon forward-looking statements as predictions of future events. Although we believe that the expectations reflected in our forward-looking statements are reasonable, we cannot guarantee that the future results, levels of activity, performance or events and circumstances reflected in the forward-looking statements will be achieved or occur. LanzaTech does not undertake any obligation to update publicly any forward-looking statements for any reason after the date of this Amendment to conform these statements to actual results or to changes in expectations, except as required by law.

 You should read this Amendment and the documents that have been filed as exhibits to the Amendment with the understanding that the actual future results, levels of activity, performance, events and circumstances of LanzaTech may be materially different from what is expected.

 Narrative to Summary Compensation Table
 We are committed to providing a fair and competitive executive compensation and benefits package that will attract, retain and reward all members of our high-performing executive team. We are also committed to providing a total compensation package that ties personal earnings to the attainment of company milestones, and the long-term achievement of our financial and operational goals.
 Our executive compensation and benefit plans strive to be:
 • Transparent: Our executives should be able to understand how we establish their pay.

 • Flexible: We support a geographically diverse organization to accommodate differences and changes in job requirements and job markets.
 • Externally Competitive: Our compensation and benefit decisions reflect pay and contribution rates for comparable jobs within the relevant labor market. Overall, we aim to provide total annual cash compensation opportunity near the market median for similar benchmark positions.
 • Internally Comparable: We will establish pay guidelines to ensure that similar executive roles jobs have similar long-term earning opportunities.
 • Aligned With Performance: We reward both corporate and individual performance through salary increases, bonuses and long-term incentives, with a particular focus on sharing in long-term company value gains.
 Cash Compensation: Generally, we position total cash compensation opportunity (defined as annual base salary plus annual target AIP opportunity) at or below the median of the selected market for talent. Executives who are newly promoted into their roles may have target cash compensation set below the external market median, with the opportunity to grow compensation to the median as the employee gains experience in the role. Executives in highly skilled and/or in-demand roles may be positioned above median in limited circumstances.
 Long-Term Incentives ("LTI"): All executives participate in an equity-based LTI plan. LTI value growth aligns with growth in the valuation and total stockholder return that we provide to our stockholders. Executives have the opportunity to earn total direct compensation levels above median if target performance goals are met or exceeded and value is created for our stockholders through increases to our stock price.
 Executive Benefits: Executives participate in the Company's broad-based benefit plans (retirement and health & welfare). Other than supplemental life and AD&D insurance with a higher multiple of salary in the event of death or disability, we offer no executive-only benefits.
 Executive Employment Agreements and Other Arrangements
 We have entered into employment agreements with each of our named executive officers (each, an "Employment Agreement," and collectively, the "Employment Agreements.")
 Base salary
 The Employment Agreements provide for each named executive officer's at-will employment. As of December 31, 2024, the annual base salaries for Dr. Holmgren, Mr. Blasko and Ms. Cuellar were $771,923, $411,692 and $381,608, respectively (amounts may be adjusted by the Board from time to time).
 Annual cash bonus
 The named executive officers are eligible for a discretionary annual cash bonus determined in accordance with the Company's bonus policy as in effect from time to time. Dr. Holmgren, Mr. Blasko and Ms. Cuellar have target cash bonuses of 100%, 60% and 50%, respectively, as a percentage of their base salary. With respect to fiscal year 2024, no cash bonus payouts were made to any of the named executive officers.
 Equity awards
 Subject to the approval of the Board, each named executive officer is eligible for discretionary equity awards under their Employment Agreement and the LanzaTech 2023 Long-Term Incentive Plan (the "2023 Plan"). In 2024, we made long-term incentive awards pursuant to the 2023 Plan using two different equity vehicles: stock options and restricted stock units. The stock options and restricted stock units granted in April 2024 vest in three equal installments, with such first installment time vesting on March 6, 2025. The stock options have a strike price equal to the closing price of our common shares on the grant date, and a ten-year term.

 Potential Termination or Change of Control Payments
 In the event the named executive officer's employment is terminated without "Cause" or the executive resigns for "Good Reason" (in each case as defined in the Employment Agreements), the Company is obligated to pay the executive: (i) a lump sum payment equal to 12 months of their then-current base salary (18 months in the case of Dr. Holmgren); (ii) an annual bonus (if any) for the year in which the termination occurs, equal to the annual bonus the executive would have received for that year based on actual performance and pro-rated based on the number of days the executive was employed during the relevant year; and (iii) if the executive is eligible for and timely elects COBRA coverage, up to 12 months (18 months in the case of Dr. Holmgren) of the portion of the executive's COBRA premium attributable to the employer contributions the Company would have paid had the executive remained employed. Additionally, if the executive's employment is terminated without Cause or for Good Reason during the period beginning 30 days prior to a "Corporate Transaction" (as defined in the Employment Agreements) and ending 24 months following a Corporate Transaction, the amount of the lump sum payment described in clause (i) will be increased from 12 months to 18 months of the executive's then-current base salary (24 months in the case of Dr. Holmgren). In addition, following: (A) a termination without "Cause" a resignation for "Good Reason" a termination on account of disability or a termination on or after becoming "Retirement Eligible" (defined under the awards granted under the 2023 Plan as when a participant is at least 60 and the sum of the participant's age and years of continuous service is 70), then a portion of the performance share units granted under the 2023 Plan will be deemed to have satisfied the time-based vesting component in an amount determined based on the product of (I) the number of performance share units that would have satisfied the time-based vesting condition on each of the applicable vesting dates and (II) a fraction equal to the amount of months that have passed from the vesting commencement date to the date of termination over the applicable denominators set forth in the award agreements, (B) a termination on account of disability or a termination on or after becoming Retirement Eligible, then a portion of the stock options and restricted stock units granted under the 2023 Plan will be deemed to have vested in an amount determined based on the product of (I) the number of stock options and restricted stock units that would have vested on each of the applicable vesting dates and (II) a fraction equal to the amount of months that have passed from the vesting commencement date to the date of termination over the applicable denominators set forth in the award agreements, and (C) a termination without "Cause" or a resignation for "Good Reason", that occurs during the period beginning 30 days prior to a Corporate Transaction and ending 24 months following a Corporate Transaction, all of the outstanding equity awards held by our executive officers pursuant to the 2023 Plan will vest in full (with any performance conditions on performance share units being treated as waived) and, with respect to Dr. Holmgren, 50% of any stock options granted under our prior long-term incentive plans which are outstanding as of the closing (the "Closing") of the Business Combination will also immediately vest.
 On February 8, 2023, the Board adopted an executive severance plan (the "Severance Plan") which became effective upon the completion of the Closing. Under the Severance Plan, qualifying employees who satisfy conditions set forth in the plan will be entitled to receive (i)12 months' base salary, in the case of a Qualifying Termination, or 18 months' base salary, in the case of a Corporate Transaction Termination (in each case, as defined in the Severance Plan), (ii) an annual bonus (if any) for the year in which the termination occurs, equal to the annual bonus the executive would have received for that year based on actual performance and pro-rated based on the number of days the executive was employed during the relevant year; and (iii) if the executive is eligible for and timely elects COBRA coverage, up to 12 months (18 months in the case of Dr. Holmgren) of the portion of the executive's COBRA premium attributable to the employer contributions the Company would have paid had the executive remained employed. With respect to clause (i), Dr. Holmgren will be entitled to receive 18 months' base salary or 24 months' base salary in the case of a Qualifying Termination or a Corporate Transaction Termination, respectively. Employees having a seniority level of vice president or higher who are designated in writing by the compensation committee of the Board, and who also meet certain other specified criteria will be eligible to participate in the Severance Plan. Our named executive officers' severance benefits under the Severance Plan are identical to what is described in clauses (i) through (iii) in the paragraph above.

 Pension Plan Benefits and Defined Contribution Plans
 The Company does not have a pension plan, defined benefit plan or other plan that provides for payments or benefits to the named executive officers at, following, or in connection with retirement.
 Non-Employee Director Compensation
 Non-employee director compensation is determined by the Board, based on the recommendation of the Compensation Committee. The Board periodically reviews non-employee director compensation to determine if changes are needed, including by comparing it to non-employee director compensation at peer companies. Employee directors receive no compensation for serving on the Board.
 After the Closing, the Board adopted a non-employee director compensation plan pursuant to which each non-employee director is entitled to receive annual cash compensation of $60,000 and annual incentive compensation in the form of time-vested restricted stock units ("RSUs") worth $100,000 for his or her service on the Board. For 2024, the number of RSUs granted was based on the 5 day VWAP price as of April 4, 2024, the date of the award, of $100,000. Additionally, the lead independent director is entitled to additional annual cash compensation of $30,000, and each member of the Audit Committee, the Compensation Committee, and the Nominating and Governance Committee is entitled to annual cash compensation of $10,000, $7,500, and $5,000, respectively. The chairperson of each such committee is entitled to additional annual cash compensation of $10,000, $7,500, and $5,000, respectively.

 Policies and Practices Related to the Grant of Certain Equity Awards Close in Time to the Release of Material Non-public Information
 The Board's and the Compensation Committee's long-term incentive award review and approval process typically occurs in connection with the regularly scheduled meeting of the Board in the first quarter of the fiscal year, generally scheduled at least several months in advance. The Board and the Compensation Committee do not schedule the approval or granting of long-term incentive awards in anticipation of the release of material non-public information ("MNPI") and do not take MNPI into account when determining the timing and terms of such awards, and the Company does not time the release of MNPI based on the grant dates of our long-term incentive awards. The Company has not timed the disclosure of MNPI for the purpose of affecting the value of its executive's compensation.
 In 2024, we did not grant equity awards to any of named executive officers within four business days before or one business day after the release of material non-public information.

 Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters
 The following table sets forth information regarding the beneficial ownership of shares of common stock as of April 21, 2025:
 • each person known by us to be the beneficial owner of more than 5% of common stock;
 • each of our named executive officers and directors; and
 • all of our executive officers and directors as a group.
 Beneficial ownership is determined in accordance with the rules and regulations of the SEC. A person is a "beneficial owner" of a security if that person has or shares "voting power," which includes the power to vote or to direct the voting of the security, or "investment power," which includes the power to dispose of or to direct the disposition of the security, or has the right to acquire such powers within 60 days.
 The beneficial ownership of shares of common stock is calculated based on 197,900,285 shares of common stock outstanding as of April 21, 2025.
 Unless otherwise noted in the footnotes to the following table, and subject to applicable community property laws, the persons and entities named in the table have sole voting and investment power with respect to their beneficially owned common stock.

 On April 3, 2025, our Board received a preliminary, nonbinding proposal from Carbon Direct Capital Management LLC ("Carbon Direct Capital") to acquire all of the outstanding shares of the Company's common stock for $0.02 per share (the "Take-Private Proposal"). Carbon Direct Capital is the holder of the Company's outstanding $40.2 million Convertible Note, excluding payment-in-kind interest from the issue date, which upon conversion, would entitle it to receive shares of common stock representing approximately 14.6% of our common stock based on the total number of shares of common stock of the Company outstanding on April 21, 2025 (see Part II, "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations-Liquidity and Capital Resources-Sources and Uses of Capital" in the Original 10-K). The Strategic Committee of the Board (the "Strategic Committee") is currently reviewing, evaluating and negotiating the Take-Private Proposal in consultation with the Company's financial advisor and legal counsel. There is no guarantee that the Take-Private Proposal will be accepted by the Strategic Committee or the Board, that definitive documentation relating to any such transaction will be executed, or that a transaction will be consummated in accordance with that documentation, if at all.
 Director Independence
 As required by Nasdaq listing standards, a majority of the members of the Board must qualify as "independent," as affirmatively determined by the Board. The Board consults with legal counsel to ensure that its determinations are consistent with all relevant securities and other laws and regulations regarding the definition of "independent," including those set forth in the applicable Nasdaq listing standards.
 We adhere to the rules of Nasdaq in determining whether a director is independent. The Nasdaq listing standards generally define an "independent director" as a person who is not an executive officer or employee, or who does not have a relationship which, in the opinion of the company's board of directors, would interfere with the exercise of independent judgment in carrying out his or her responsibilities as a director. The Board has determined that Barbara Byrne, Reyad Fezzani, Jill Frizzley, Nigel Gormly, Dorri McWhorter, Jim Messina, Thierry Pilenko and Gary Rieschel are independent directors of the Company. Our independent directors have regularly scheduled meetings at which only independent directors are present.
