1 INVESTORS’ RIGHTS AGREEMENT This INVESTORS’ RIGHTS AGREEMENT (as amended, restated, supplemented or otherwise modified from time to time, this “Agreement”), dated as of May 7, 2025, is made by and among LanzaTech Global, Inc., a Delaware corporation (the “Company”), and each of the Parties listed on Exhibit A hereto from time to time as an “Investor” (each, an “Investor” and, collectively, the “Investors” and, together with the Company, the “Parties”). Capitalized terms used in this Agreement and not otherwise defined shall have the meanings specified in Section 7.1. PRELIMINARY STATEMENTS A. Concurrently with the execution and delivery hereof, the Company shall issue and sell to the Investors, and the Investors shall purchase from the Company, an aggregate of 20,000,000 shares of Preferred Stock designated as “Series A Convertible Senior Preferred Shares” (the “Series A Preferred Stock”) on the terms and subject to the conditions set forth in the Purchase Agreement. B. The Company has filed with the Secretary of State of the State of Delaware the Certificate of Designation, which sets forth certain designations, rights, preferences, powers, restrictions and limitations of the Series A Preferred Stock. C. The Parties each desire to enter into this Agreement to establish certain additional rights, preferences, powers, qualifications, restrictions and limitations of the Series A Preferred Stock. NOW, THEREFORE, in consideration of the foregoing premises and the respective representations, warranties, covenants and agreements contained herein and other good and valuable consideration the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, the parties hereby agree as follows: ARTICLE I BOARD OF DIRECTORS; VOTING AGREEMENT SECTION 1.1 Election of the Series A Director. For so long as any Series A Preferred Stock remains outstanding, the Investors, exclusively and voting together as a separate class on an as-converted to Common Stock basis, shall be entitled to elect one director of the Company (the “Series A Director”). For the avoidance of doubt, the Series A Director shall not be included in any of the classes created pursuant to Article V of the Certificate of Incorporation. Notwithstanding anything to the contrary in this Agreement or in the Certificate of Designation, the Investors shall not elect any individual to serve as the Series A Director unless such individual satisfies the Nasdaq rules and Securities Laws applicable to service as a director of a publicly-listed company. For the avoidance of doubt, the provisions of this Section 1.1 are in furtherance of, and not in addition to, the rights set forth in Section 3(b) of the Certificate of Designation. SECTION 1.2 Vacancies and Removal. The Investors, exclusively and voting together as a separate class on an as-converted to Common Stock basis, shall be entitled to fill any vacancies created by the resignation, removal or death of the Series A Director (and any replacement thereof). SECTION 1.3 Voting Agreement. Each Investor hereby agrees to vote, or cause to be voted, all shares of Series A Preferred Stock owned beneficially or of record by such Investor, or over which such Investor maintains voting control, directly or indirectly, in such manner as may be necessary or advisable in support of, or to implement, maintain, or protect the various matters set forth in, and the intent of, this Article I, whether at an annual or special meeting of stockholders of the Company or pursuant to any written consent of the stockholders of the Company.

2 ARTICLE II RESTRICTIONS ON TRANSFER OF SERIES A PREFERRED STOCK SECTION 2.1 Transfers Generally. Any Proposed Holder Transfer not made in compliance with the requirements of this Agreement shall be null and void ab initio, shall not be recorded on the books of the Company or its transfer agent and shall not be recognized by the Company. Each Party acknowledges and agrees that any breach of this Agreement would result in substantial harm to the other parties hereto for which monetary damages alone could not adequately compensate. Therefore, the Parties unconditionally and irrevocably agree that any non-breaching Party shall be entitled to seek protective orders, injunctive relief and other remedies available at law or in equity (including, without limitation, seeking specific performance or the rescission of purchases, sales and other transfers of Transfer Stock not made in strict compliance with this Agreement). SECTION 2.2 Permitted Transfers. (a) Each Holder may Transfer any Preferred Stock (a “Permitted Transfer”) to (i) other Holders and their respective Affiliates (including, for the avoidance of doubt, their limited partners and accounts or funds managed or advised by the holders of their respective Affiliates) and (ii) other Persons reasonably acceptable to the Company; provided, that, in the case of the foregoing clauses (i) and (ii), each such Prospective Transferee shall provide to the Company a properly completed and executed Internal Revenue Service (“IRS”) Form W-9 or appropriate IRS Forms W-8 claiming complete exemption from dividend withholding tax before such Transfer shall be effective; provided, further, that no Transfer shall be made in violation of the Securities Act or any applicable state securities Laws or that results (or could reasonably be expected to result) in the Company being required to register the Preferred Stock pursuant to applicable securities Laws. In connection with any Permitted Transfer, such Prospective Transferee shall execute and deliver to the Company a preferred holder joinder, in the form of Exhibit B attached hereto, at the time of or prior to any Transfer (unless such Prospective Transferee is a Holder before giving effect to such Transfer). (b) The Company shall keep at its principal office a register for the registration of the Preferred Stock. Upon the surrender of any certificate representing any Preferred Stock at the Company’s principal office, the Company shall, upon the request of the Holder of such certificate, promptly (but in any event within three Business Days after such request) prepare, execute and deliver (at the Company’s expense) new certificates in exchange therefor representing Preferred Stock represented by the surrendered certificate. Subject to compliance with this Article II, such certificate shall be registered in the name requested by the Holder of the surrendered certificate. The issuance of such new certificates shall be made without charge to the Holders, and the Company shall pay for any cost incurred by the Company in connection with such issuance, including any documentary, stamp and similar issuance or transfer tax in respect of the preparation, execution and delivery of such new certificates pursuant to this Section 2.2(b). All transfers and exchanges of Preferred Stock shall be made promptly by direct registration on the books and records of the Company and the Company shall take all such other actions as may be required to reflect and facilitate all transfers and exchanges not prohibited by this Article II. (c) Upon receipt of evidence reasonably satisfactory to the Company (it being understood that an affidavit of the applicable Holder shall constitute such evidence) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing Preferred Stock, and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Company, or, in the case of any such mutilation upon surrender of such certificate, the Company shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the Preferred Stock represented by such lost, stolen, destroyed or mutilated certificate and dated the date of such lost, stolen, destroyed or mutilated certificate.

3 (d) Unless otherwise agreed to by the Company and the applicable Holder, each certificate representing Series A Preferred Stock shall bear a restrictive legend in substantially the form attached hereto as Annex I and shall be subject to the restrictions set forth therein. In addition, such certificate may have notations, additional legends or endorsements required by law, exchange rules or agreements to which the Company and any Holder (in its capacity as a Holder) is subject, if any. SECTION 2.3 Right of First Refusal. (a) Subject to the terms of Section 2.2, each Holder hereby unconditionally and irrevocably grants to the Significant Holders a Right of First Refusal to purchase all or any portion of Transfer Stock that such Holder may propose to transfer in a Proposed Holder Transfer, at the same price and on the same terms and conditions as those offered to the Prospective Transferee. (b) Each Holder proposing to make a Proposed Holder Transfer must deliver a Proposed Transfer Notice to each Significant Holder not later than 45 days prior to the consummation of such Proposed Holder Transfer. Such Proposed Transfer Notice shall contain the material terms and conditions (including price and form of consideration) of the Proposed Holder Transfer, the identity of the Prospective Transferee and the intended date of the Proposed Holder Transfer. To exercise its Right of First Refusal under this Article II, the Exercising Significant Holder must deliver a Significant Holder Notice to the selling Holder and the other Significant Holders within 15 days after delivery of the Proposed Transfer Notice specifying the number of shares of Transfer Stock to be purchased by such Exercising Significant Holder. (c) If any Holder becomes obligated to sell any Transfer Stock to any Significant Holder under this Agreement and fails to deliver such Transfer Stock in accordance with the terms of this Agreement, the Significant Holder may, at its option, in addition to all other remedies it may have, send to such Holder the purchase price for such Transfer Stock as is herein specified and transfer to the name of the Significant Holder (or request that the Company effect such transfer in the name of a Significant Holder) on the Company’s books any certificates, instruments, or book entry representing the Transfer Stock to be sold. ARTICLE III CERTAIN COVENANTS SECTION 3.1 Information Rights. Without the prior affirmative vote or written consent of the Majority Holders approving such action or omission, the Company shall, so long as any Series A Preferred Stock remains outstanding, furnish to the Investors: (a) within 120 days after the end of each fiscal year of the Company, (i) a balance sheet as of the end of such year, (ii) statements of income and of cash flows for such year and (iii) a statement of stockholders’ equity as of the end of such year, all such financial statements audited and certified by an independent certified public accountant of recognized national standing; provided, however, the obligations under this Section 3.1(a) may be satisfied with respect to any financial statements of the Company by furnishing the Company’s Form 10-K for such fiscal year filed with the SEC or any securities exchange within the time period specified in this clause (a); and (b) within 75 days after the end of each of the first three fiscal quarters of each fiscal year of the Company, unaudited statements of income and cash flows for such fiscal quarter, and an unaudited balance sheet as of the end of such fiscal quarter, all prepared in accordance with GAAP (except that such financial statements may (x) be subject to normal year-end audit adjustments; and (y) not contain all notes thereto that may be required in accordance with GAAP); provided, however, the obligations under this clause (b) may be satisfied with respect to any financial statements of the Company by furnishing the

4 Company’s Form 10-Q for such fiscal quarter filed with the SEC or any securities exchange within the time period specified in this clause (b). SECTION 3.2 Confidentiality. The Holders shall treat confidentially, and shall cause their Affiliates and Representatives to treat confidentially all information received pursuant to Section 3.1 that is not publicly available at the time of receipt until such time that such information becomes publicly available other than by reason of improper disclosure by the Holders or any of their respective Affiliates or Representatives. SECTION 3.3 Withholding Taxes. (a) Each Holder of Series A Preferred Stock acknowledges and agrees that it is, and it and any permitted transferee shall be, for so long as it is a Holder of Series A Preferred Stock, a (i) “United States person” as defined in section 7701(a)(30) of the Internal Revenue Code of 1986, as amended (the “Code”) or (ii) “foreign government” within the meaning of section 892 of the Code that is eligible and claiming the benefits of the exemption from taxation under section 892 of the Code and, in each case, shall provide a properly completed and executed IRS Form W-9 or appropriate Form(s) W-8 claiming complete exemption from dividend withholding. (b) Each applicable Holder of shares of Preferred Stock shall indemnify the Company for any withholding taxes (and any interest or penalties imposed thereon) imposed on the Company with respect to amounts payable with respect to such Holder’s Preferred Stock. To the extent that any Holder may be required to indemnify the Company hereunder, such Holder and the Company may jointly control the related withholding tax audit or other proceeding and neither Party shall settle such claim without the consent of the other Party, which consent shall not be unreasonably withheld, conditioned or delayed.

SECTION 4.2 No Recourse.

5 SECTION 4.3 Governing Law. This Agreement shall be governed by, and construed in accordance with, the Laws of the State of Delaware, without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware. SECTION 4.4 Jurisdiction. Except as otherwise expressly provided in this Agreement, each of the Parties hereto hereby irrevocably submits to the exclusive jurisdiction of the Court of Chancery of the State of Delaware or, if such court does not have subject matter jurisdiction, any other state or federal court located in the State of Delaware, over any suit, action or other proceeding brought by any party arising out of or relating to this Agreement, and each of the Parties hereto hereby irrevocably agrees that all claims or disputes with respect to any such suit, action or other proceeding shall be heard and determined in such courts.

TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW WHICH CANNOT BE WAIVED, EACH OF THE PARTIES HERETO HEREBY WAIVES AND COVENANTS THAT IT WILL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE) ANY RIGHT TO TRIAL BY JURY IN RESPECT OF ANY ISSUE, ACTION, CLAIM, CAUSE OF ACTION OR SUIT (IN CONTRACT, TORT OR OTHERWISE), IN ANY WAY ARISING OUT OF OR RELATED TO THIS AGREEMENT, ITS NEGOTIATION OR TERMS, OR THE TRANSACTIONS, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING. EACH OF THE PARTIES HERETO ACKNOWLEDGES THAT THIS SECTION 4.5 CONSTITUTES A MATERIAL INDUCEMENT UPON WHICH SUCH OTHER PARTIES ARE RELYING AND WILL RELY IN ENTERING INTO THIS AGREEMENT AND ANY OTHER AGREEMENTS RELATING HERETO OR CONTEMPLATED HEREBY. ANY PARTY HERETO MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION 4.5 WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF EACH SUCH PARTY TO THE WAIVER OF ITS RIGHT TO TRIAL BY JURY. SECTION 4.6 Specific Performance; Remedies. The parties hereby expressly recognize and acknowledge that immediate, extensive and irreparable damage would result, no adequate remedy at law would exist, and damages would be difficult to determine in the event that any provision of this Agreement is not performed in accordance with its specific terms or otherwise breached. Therefore, in addition to, and not in limitation of, any other remedy available to any party hereto, a party under this Agreement will be entitled to specific performance of the terms hereof and immediate injunctive relief, without the necessity of proving the inadequacy of money damages as a remedy and without bond or other security being required. Such remedies, and any and all other remedies provided for in this Agreement, will, however, be cumulative in nature and not exclusive and will be in addition to any other remedies whatsoever which any party may otherwise have. Each of the parties hereto hereby acknowledges and agrees that it may be difficult to prove damages with reasonable certainty, that it may be difficult to procure suitable substitute performance, and that injunctive relief and/or specific performance will not cause an undue hardship to the parties. Each of the parties hereto hereby further acknowledges that the existence of any other remedy contemplated by this Agreement does not diminish the availability of specific performance of the obligations hereunder or any other injunctive relief. Each party hereto hereby further agrees that in the event of any action by any other party for specific performance or injunctive relief, it will not assert that a remedy at law or other remedy would be adequate or that specific performance or injunctive relief in respect of such

6 breach or violation should not be available on the grounds that money damages are adequate or any other grounds. SECTION 4.7 Notice.
