CAUTIONARY NOTE ON FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q filed by LanzaTech Global, Inc. together with its consolidated subsidiaries, contains statements that are forward-looking and as such are not historical facts. 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 Quarterly Report, 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. Such statements are based on the beliefs of, as well as assumptions made by and information currently available to, LanzaTech’s management.

Forward-looking statements may include, for example, statements about:

•our anticipated growth rate and market opportunities;

•our ability to maintain the listing of our securities on the Nasdaq Stock Market;

•the potential liquidity and trading of our securities;

•our ability to raise financing in the future;

•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;

•our receipt of substantial additional financing to fund our operations and complete the development and commercialization of our process technologies;

•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 attract, retain and motivate qualified personnel and to manage our growth effectively;

•our future financial performance and capital requirements; 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 Quarterly Report.

These forward-looking statements are only predictions based on our current expectations and projections about future events and are subject to a number of risks, uncertainties and assumptions, including the risk factors discussed in Part II, Item 1A of this Quarterly Report in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2022, and in other documents as we filed from time to time with the Securities and Exchange Commission (“SEC”). Moreover, we operate in a competitive industry, and new risks emerge from time to time. It is not possible for the management of LanzaTech 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 Quarterly Report may not occur, and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements in this Quarterly Report.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1 — Description of the Business

LanzaTech Global, Inc., formerly known as AMCI Acquisition Corp. II (“AMCI”) prior to February 8, 2023 (the “Closing Date”) was incorporated as a Delaware corporation on January 28, 2021.

On March 8, 2022, LanzaTech NZ, Inc. ("Legacy LanzaTech") entered into an Agreement and Plan of Merger (the “Merger Agreement”) with AMCI and AMCI Merger Sub, Inc. a Delaware corporation and a wholly owned subsidiary of AMCI (“Merger Sub”). On February 8, 2023, Legacy LanzaTech completed its business combination with AMCI by which the Merger Sub merged with and into Legacy LanzaTech, with Legacy LanzaTech continuing as the surviving corporation and as a wholly owned subsidiary of AMCI (the “Business Combination”). The reporting entity is LanzaTech Global, Inc. and its subsidiaries (collectively referred to herein as “the Company” or "LanzaTech").

The Company is headquartered in Skokie, Illinois. The Company is a nature-based carbon refining company that transforms waste carbon into the chemical building blocks for consumer goods such as sustainable fuels, fabrics, and packaging that people use in their daily lives. The Company’s customers leverage its proven proprietary gas fermentation technology platform to convert certain feedstock, including waste carbon gases, into sustainable fuels and chemicals such as ethanol. The Company performs related services such as feasibility studies, engineering services, and research and development ("R&D") in biotechnology for commercial and government customers. The Company also purchases low carbon chemicals produced at customer facilities employing the Company’s technology and sells it under the brand name CarbonSmart. We have also been developing the capabilities to produce single cell protein as a primary product from our gas fermentation platform.

As of September 30, 2023, licensees of the Company’s technology operate four commercial-scale waste-to-gas ethanol plants in China and started operations of another one in India, with others currently in development in various countries, compared to three commercial scale waste-to-gas ethanol plants in China as of September 30, 2022.

The Company has reclassified its warrants on preferred shares as of December 31, 2022 from other accrued liabilities to warrants on the condensed consolidated balance sheet to conform with current period presentation. This reclassification resulted in a decrease to other accrued liabilities and corresponding increase to warrants of $2,119 as of December 31, 2022.

As a result of the Business Combination, the Company’s common stock trades under the ticker symbol “LNZA” and its Public Warrants trade under the ticker symbol “LNZAW” on the Nasdaq Stock Market. Prior to the consummation of the Business Combination, the Company’s common shares were listed on Nasdaq Stock Market under the symbol “AMCI” and the Public Warrants were listed on the Nasdaq Stock Market under the symbol “AMCI-W”.

Unless otherwise indicated, amounts in these financial statements are presented in thousands, except for share and per share amounts.

Note 2 — Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles for interim financial information, and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America ("US GAAP"), the accounting principles, standards, and procedures adopted by the U.S. Securities and Exchange Commission, for complete financial statements. However, in the opinion of management, all adjustments (consisting of normal recurring accruals) have been made that are necessary for a fair presentation of the condensed consolidated financial statements for the interim periods. For further information refer to the Consolidated Financial Statements and Footnotes thereto included in Legacy LanzaTech's Annual Report for the year ended December 31, 2022 included in the Company’s prospectus filed with the SEC on May 25, 2023.

The Business Combination is accounted for as a reverse recapitalization as Legacy LanzaTech was determined to be the accounting acquirer under Accounting Standards Codification (“ASC”) 805, Business Combinations (“ASC 805”) based on the evaluation of the following facts and circumstances:

•Legacy LanzaTech stockholders have the largest portion of voting rights (85.3% at the closing of the Business Combination) in the Company;

•Legacy LanzaTech’s existing senior management team comprise senior management of the Company;

•The operations of the Company primarily represent operations of Legacy LanzaTech; and

•In comparison with AMCI, Legacy LanzaTech has significantly more revenue and total assets.

Accordingly, for accounting purposes, the financial statements of the Company represent a continuation of the financial statements of Legacy LanzaTech with the acquisition being treated as the equivalent of Legacy LanzaTech issuing stock for the net assets of AMCI, accompanied by a recapitalization. The net assets of AMCI were stated at historical cost, with no goodwill or other intangible assets recorded. Legacy LanzaTech was deemed to be the predecessor, and the consolidated assets and liabilities and results of operations prior to February 8, 2023 are those of Legacy LanzaTech. Reported shares and earnings per share available to common stockholders, prior to the Business Combination, have been retroactively restated to reflect the exchange ratio established in the Merger Agreement. The number of shares of preferred stock was also retroactively restated based on the exchange ratio.

Variable Interest Entity (“VIE”)

The Company makes judgments in determining whether an entity is a VIE and, if so, whether it is the primary beneficiary of the VIE and is thus required to consolidate the entity. A VIE is a legal entity that has a total equity investment that is insufficient to finance its activities without additional subordinated financial support or whose equity investors lack the characteristics of a controlling financial interest. The Company’s variable interest arises from contractual, ownership or other monetary interests in the entity, which changes with fluctuations in the fair value of the entity’s net assets. A VIE is consolidated by its primary beneficiary, the party that has both the power to direct the activities that most significantly impact the VIE’s economic performance, and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. The Company consolidates a VIE when the Company is deemed to be the primary beneficiary. The Company assesses whether or not the Company is the primary beneficiary of a VIE on an ongoing basis. If the Company is not deemed to be the primary beneficiary in a VIE, the Company accounts for the investment or other variable interests in a VIE in accordance with applicable US GAAP.

The Company holds interests in certain VIEs for which it has been determined the Company is not the primary beneficiary. The Company's variable interests primarily relate to entities in which the Company has a non-controlling equity interest. Although these financial arrangements resulted in holding variable interests in these entities, they do not empower the Company to direct the activities of the VIEs that most significantly impact the VIEs' economic performance. The Company's interests in the VIEs are, therefore, accounted for under the equity method of accounting or at fair value (including, when applicable, the practicability exception to fair value under ASC 321-10-35). Refer to Note 6 - Investments, for further information. The Company is exposed to the VIEs’ losses and other impairment indicators up to the carrying value of each investment and any amounts receivable from the VIE, less amounts payable. Refer to Note 12, Related Party Transactions, for further details on the transactions with VIEs.

Going Concern

The accompanying condensed consolidated financial statements of the Company have been prepared in accordance with US GAAP and assuming the Company will continue as a going concern. The going concern basis of presentation assumes that the Company will continue in operation one year after the date these financial statements are issued and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. The Company had cash and cash equivalents of $91,397, short and long-term held-to-maturity debt investments of $44,791 and an accumulated deficit of $(813,198) as of September 30, 2023 and cash outflows

from operations of $(81,565) and a net loss of $(115,424) for the nine months ended September 30, 2023. As a result of the Business Combination described in Note 1 closing on February 8, 2023, the Company received $153,285, which represents the proceeds from the Business Combination received net of (1) transaction expenses, (2) the PIPE investment and (3) the amount paid to ACM ARRT H LLC (“ACM”) and Vellar Opportunity Fund SPV LLC - Series 10 (“Vellar”) in relation to the Forward Purchase Agreement (see below).

The Company has historically funded its operations through debt financing and issuances of equity securities. Based on the Company’s financial position as of the date the condensed consolidated financial statements were issued, the Company projects that it will be able to cover its liquidity needs for the next twelve months.

Use of Estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates include fair value of equity awards granted to both employees and non-employees, revenue recognized over time, AM SAFE, Brookfield SAFE, AM SAFE warrants, the Forward Purchase Agreement and the Private Placement Warrants.

The Company uses the percentage of completion for both input and output methods to recognize revenue over time for certain contracts with customers. Under the output method, the Company exercises judgment and estimation when determining the percentage of completion against the total transaction price initially estimated. Under the input method, the Company exercises judgment and estimation when selecting the most indicative measure of such performance.

Most of our arrangements provide fixed consideration, however, when there are variable consideration elements, the Company estimates the transaction price and whether revenue should be constrained. Significant estimates and judgments are also used when a material right is provided to the customer. In these instances, the Company estimates the stand-alone selling price and apportions the total transaction price to this material right. Refer to the Revenue Recognition section in Note 2 hereunder.

Changes in facts and circumstances or additional information may result in revised estimates, and actual results may differ from these estimates.

Segment Information

The Company operates as one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker (“CODM”), in deciding how to allocate resources and assess performance.

While the Company offers a variety of services and operates in multiple countries, the Company’s business operates in one operating segment because most of the Company’s service offerings are delivered and supported on a global basis, most of the Company’s service offerings are deployed in a similar way, and the Company’s CODM evaluates the Company’s financial information and resources and assesses the performance of these resources on a consolidated basis. There are no segment managers who are held accountable by the CODM, or anyone else, for operations, operating results, and planning for components below the consolidated level. Accordingly, the Company has determined that it has a single reportable and operating segment. See Note 5 - Revenues, for disaggregation of the Company’s revenues by customer location and contract type.

Foreign Currencies

The Company’s reporting currency is the U.S. Dollar. The Company has certain foreign subsidiaries where the functional currency is the local currency. All of the assets and liabilities of these subsidiaries are translated to U.S. dollars at the exchange rate in effect at the balance sheet date, income and expense accounts are translated at average rates for the period, and shareholders’ equity accounts are translated at historical rates. The effects of translating

financial statements of foreign operations into the Company’s reporting currency are recognized in accumulated other comprehensive income.

The Company also has foreign subsidiaries that have a functional currency of the U.S. dollar. Purchases and sales of assets and income and expense items denominated in foreign currencies are remeasured into U.S. dollar amounts on the respective dates of such transactions. Net realized and unrealized foreign currency gains or losses relating to the differences between these recorded amounts and the U.S. dollar equivalent actually received or paid are included within other expense, net in the condensed consolidated statements of operations and comprehensive loss.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less at the time of purchase to be cash equivalents. As of September 30, 2023 and December 31, 2022, the Company had $91,397 and $83,045 of cash and cash equivalents, respectively.

Restricted Cash

The Company is required to maintain a cash deposit with a bank which consists of collateral on certain travel and expense programs maintained by the bank. The following represents a reconciliation of cash and cash equivalents in the condensed consolidated balance sheets to total cash, cash equivalents and restricted cash in the condensed consolidated statements of cash flows as of September 30, 2023 and December 31, 2022.


	As of
	September 30, 2023		December 31, 2022
Cash and cash equivalents	$	91,397	$	83,045
Restricted cash (presented within Other current assets)	673		665
Cash, cash equivalents and restricted cash	$	92,070	$	83,710

Trade and Other Receivables

Receivables are reported net of allowances for doubtful accounts. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of customers to make required payments. The Company estimates the allowance for doubtful accounts based on a variety of factors including the length of time receivables are past due, the financial health of customers, unusual macroeconomic conditions, and historical experience. As of September 30, 2023 and December 31, 2022, the Company recognized an allowance for doubtful accounts of $1,751 and $1,051, respectively.

Investment securities

The Company classifies investment securities according to their purpose and holding period. All investment securities are debt securities that have been classified as held-to-maturity (“HTM”) because the Company has both the ability and intent to hold the securities to maturity.

HTM debt securities are comprised of U.S. Treasury bills, U.S. Treasury notes, Yankee bonds, and corporate debt. HTM debt securities are carried at amortized cost, which is original cost net of periodic principal repayments and amortization of premiums and accretion of discounts. Accrued interest receivable is recorded within trade and other receivables, net of allowance on the condensed consolidated balance sheets. Amortization of premiums and accretion of discounts are computed using the contractual level-yield method (contractual interest method), adjusted for actual prepayments. The contractual interest method recognizes the income effects of premiums and discounts over the contractual life of the securities based on the actual behavior of the underlying assets, including adjustments for actual prepayment activities, and reflects the contractual terms of the securities without regard to changes in estimated prepayments based on assumptions about future borrower behavior.

Held-to-maturity securities are evaluated individually on a quarterly basis for expected credit losses. If applicable, an allowance for credit losses is recorded with a corresponding credit loss expense (or reversal of credit loss expense). The allowance for credit losses excludes uncollectible accrued interest receivable, which is measured separately.

Warrants

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in ASC 480, Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815-40, Derivatives and Hedging—Contracts in Entity’s Own Equity (“ASC 815-40”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815-40, including whether the warrants are indexed to the Company’s own common stock, among other conditions for equity classification.

For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded at fair value as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance and adjusted to the current fair value at each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss in other expense, net on the condensed consolidated statement of operations and comprehensive loss (see Note 7 - Warrants).

Forward Purchase Agreement

On February 3, 2023, the Company entered into a Forward Purchase Agreement (“FPA”) with ACM. On the same date, ACM partially assigned its rights under the FPA to Vellar. ACM and Vellar are together referred to as the “Purchasers”. Pursuant to the Forward Purchase Agreement, the Purchasers obtained 5,916,514 common shares (“Recycled Shares”) on the open market for $10.16 per share (“Redemption Price”), and such purchase price of $60,096 was funded by the use of AMCI trust account proceeds as a prepayment (“Prepayment Amount”) for the Forward Purchase Agreement redemption 3 years from the date of the Business Combination (“Maturity Date”). The Maturity Date may be accelerated, at the Purchasers discretion, if the Company share price trades below $3.00 per share for any 50 trading days during a 60 day consecutive trading-day period or the Company is delisted. On any date following the Business Combination, the Purchasers also have the option to early terminate the arrangement in whole or in part by providing optional early termination notice to the Company (the “Optional Early Termination”). For those shares early terminated (the “Terminated Shares”), the Purchasers will owe the Company an amount equal to the Terminated Shares times the Redemption Price, which may be reduced in the case of certain dilutive events (“Reset Price”).

At the Maturity Date, the Company is obligated to pay the Purchasers an amount equal to the product of (1) 7,500,000 less (b) the number of Terminated Shares multiplied by (2) $2.00 (the “Maturity Consideration”). In addition to the Maturity Consideration, on the Maturity Date, the Company shall pay to the Purchasers an amount equal to the product of (x) 500,000 and (y) the Redemption Price, totaling $5,079 (the “Share Consideration”). If the Purchasers were to utilize their Optional Early Termination to terminate the FPA early, neither the Maturity Consideration nor the Share Consideration would be due to the Purchasers.

The Purchasers’ Optional Early Termination economically results in the prepaid forward contract being akin to an in-substance written put option with the Purchaser’s right to sell all or a portion of the 5,916,514 common shares to the Company. The Company is entitled over the 36-month maturity period to either a return of the prepayment or the underlying shares, which the Purchasers will determine at their sole discretion.

The FPA consists of three freestanding financial instruments compromising the in-substance written put option (“FPA Put Option”), the minimum portion of the Maturity Consideration (the “Minimum Maturity Consideration”), and the Share Consideration. The FPA Put Option is a derivative instrument the Company has recorded as a liability and measured at fair value. The difference between the initial value of the derivative, including Maturity Consideration in excess of the Minimum Maturity Consideration (the “Variable Maturity Consideration”), and the Prepayment Amount was recorded in the condensed consolidated statement of operations and comprehensive loss.

Subsequent changes in fair value of the derivative liability are also recorded in other expense, net on the condensed consolidated statement of operations and comprehensive loss. The Prepayment Amount was accounted for as a reduction to equity to reflect the substance of the overall arrangement as a net repurchase of the Recycled Shares.

The Minimum Maturity Consideration, representing 7,500,000 less 5,916,513 multiplied by $2.00 or $3,167, and the Share Consideration are considered to be free-standing debt instruments. The Company has elected to measure these using the Fair Value Option (“FVO”) under ASC 825, Financial Instruments (“ASC 825”). As both the Minimum Maturity Consideration and the Share Consideration will be paid on the same terms and at the same time, these are accounted for together and referred to as the “Fixed Maturity Consideration”. The Variable Maturity Consideration is captured as part of the in-substance written put derivative liability (the FPA Put Option), as noted above. The Fixed Maturity Consideration is recorded as long-term liability on the condensed consolidated balance sheets. The initial value of the Fixed Maturity Consideration is recorded through the condensed consolidated statement of operations and comprehensive loss. Subsequent changes in fair value of the Fixed Maturity Consideration are also recorded in other expense, net on the condensed consolidated statement of operations and comprehensive loss.

Prior to filing these financial statements on Form 10-Q, we determined that our prior interpretation of the accounting guidance applicable to certain elements of the Forward Purchase Agreement (“FPA”) was incorrect. As a result, we have revised the accounting treatment of the FPA in our financial statements as of September 30, 2023 to reclassify the Prepayment Amount of $60.5 million, previously recorded as part of a net non-current derivative asset in the condensed consolidated balance sheet, to the equity section of the condensed consolidated balance sheet. The remaining liability balance of $38.1 million associated with the FPA, including the Minimum Maturity Consideration and the Share Consideration, are now reflected as non-current liabilities in our condensed consolidated balance sheet.

The change in accounting for the FPA did not have any impact on our liquidity, cash flows or results of operations for the third quarter. We intend to restate our financial statements for the quarters ended March 31, 2023 and June 30, 2023 to be consistent with this accounting treatment.

Revenue Recognition

The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). The Company primarily earns revenue from services related to biorefining (formerly known as carbon capture and transformation) which includes feasibility studies and basic engineering design of commercial plants, licensing of technologies and sales of biocatalysts. The other two revenue streams are: (1) joint development and contract research activities to develop and optimize novel biocatalysts, related processes and technologies, and (2) supply of chemical building blocks for sustainable products produced using the Company’s proprietary technologies (referred to as CarbonSmart).

Revenue is measured based on the consideration specified in a contract with a customer. The Company records taxes collected from customers and remitted to governmental authorities on a net basis. The Company’s payment terms are between 30-60 days and can vary by customer type and products offered. Management has evaluated the terms of the Company’s arrangements and determined that they do not contain significant financing components.

Biorefining

The Company provides feasibility studies and basic design and engineering services used for detailed design, procurement, and construction of commercial plants that utilize the Company’s technologies, along with the sale of microbes and media. The services provided are recognized as a performance obligation satisfied over time. Revenue is recognized using the output method based on milestone completion, the cost-to-cost input method for certain engineering services, or the percentage of completion method as performance obligations are satisfied. Revenue for the sale of microbes and media is at a point in time, depending on when control transfers to the customer.

The Company licenses intellectual property to generate recurring revenue, in the case of running royalties, or one-time revenue, in the case of fixed consideration royalties, when its customers deploy the Company’s technology in their biorefining plants. When licenses are considered to be distinct performance obligations, the recognition of

revenue is dependent on the terms of the contract, which may include fixed consideration or royalties based on sales or usage, in which case the revenue is recognized when the subsequent sale or usage occurs or when the performance obligation to which some or all of the sales or usage-based royalty is allocated has been satisfied, whichever is later.

Joint Development and Contract Research

The Company performs R&D services related to novel technologies and development of biocatalysts for commercial applications, mainly to produce fuels and chemicals. The Company engages in two main types of R&D services – joint development agreements, and contract research, including projects with the U.S. Department of Energy and other US and foreign government agencies. Such services are recognized as a performance obligation satisfied over time. Revenue is recognized based on milestone completion, when payments are contingent upon the achievement of such milestones, or based on percentage-completion method when enforceable rights to payment exist. When no milestones or phases are clearly defined, management has determined that the cost incurred, input method, is an appropriate measure of progress towards complete satisfaction of the performance obligations under ASC 606, and estimates its variable consideration under the expected value method.

Revenue is not recognized in advance of customer acceptance of a milestone when such acceptance is contractually required. Payments for R&D services with no contractual payments are not due from customers until a technical report is submitted; therefore, a contract asset is recognized at milestone completion but prior to the submission of a technical report. The contract asset represents the Company’s right to consideration for the services performed at milestone completion. Occasionally, customers provide payments in advance of the Company providing services which creates a contract liability for the Company. The contract liability represents the Company's obligation to provide services to a customer.

CarbonSmart

The Company purchases chemical building blocks from the customers who have deployed our proprietary technologies in their biorefining plants and sells them as CarbonSmart products. Revenue is recognized at a point in time when control transfers to our end customer, which varies depending on the shipping terms. The Company acts as the principal in such transactions and accordingly, recognizes revenue and cost of revenues on a gross basis. Amounts received for sales of CarbonSmart products are classified as Revenue from contract with customers - tangible products in the condensed consolidated statements of operations and comprehensive loss.

Collaboration Arrangements

The Company has certain partnership agreements that are within the scope of ASC 808, Collaborative Arrangements, which provides guidance on the presentation and disclosure of collaborative arrangements. Generally, the classification of the transaction under the collaborative arrangements is determined based on the nature of the contractual terms of the arrangement, along with the nature of the operations of the participants. The Company’s collaborative agreements generally include a provision of R&D services related to novel technologies and biocatalysts. Amounts received for these services are classified as Revenue from collaborative arrangements in the condensed consolidated statements of operations and comprehensive loss. The Company's R&D services are a major part of the Company's ongoing operations and therefore ASC 606 is applied to recognize revenue.

Fair Value of Financial Instruments

Fair value is defined as the exchange price that would be received for an asset or an exit price paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy defines a three-level valuation hierarchy for disclosure of fair value measurements as follows:

Level 1 — Valuations based on quoted prices in active markets for identical assets or liabilities that an entity has the ability to access;

Level 2 — Valuations based on quoted prices for similar assets or liabilities, quoted prices for identical assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities; and

Level 3 — Valuations based on inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC 820, Fair Value Measurement, approximates the carrying amounts represented in the accompanying condensed consolidated balance sheets, primarily due to their short-term nature, except for the warrant liability.

Concentration of Credit Risk and Other Risks and Uncertainties

Revenue generated from the Company’s customers outside of the United States for the three months ended September 30, 2023 and 2022 was approximately 75% and 54%, respectively. Revenue generated from the Company’s customers outside of the United States for the nine months ended September 30, 2023 and 2022 was approximately 75% and 61%, respectively.

As of September 30, 2023 and December 31, 2022, approximately 49% and 35%, respectively, of trade accounts receivable and unbilled accounts receivable were due from customers located outside the United States. As of September 30, 2023 and December 31, 2022, the value of property, plant, and equipment outside the United States was immaterial.

The Company’s revenue by geographic region based on the customer’s location is presented in Note 5, Revenues.

Customers

Customers representing 10% or greater of revenue were as follows for the three and nine months ended September 30, 2023 and 2022:


	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Customer A	36	%	—	%	39	%	10	%
Customer B	7	%	27	%	8	%	24	%
Customer C	—	%	21	%	—	%	10	%

Stock-Based Compensation

In exchange for certain employee and director services, compensation is given in the form of equity-based awards. The Company accounts for equity-based compensation in accordance with ASC 718, Compensation – Stock Compensation. Accordingly, equity-classified awards are recorded based on the grant date fair value and expensed over the requisite service period for the respective award. Liability-classified awards are remeasured at the end of each reporting period and expensed based on the percentage of requisite service that has been rendered.

The Company’s equity-based awards include stock option awards, restricted stock units, stock-appreciation rights (“SARs”) and restricted stock issued by the Company, which vest based on either time and/or the achievement of certain market or performance conditions. The Company records forfeitures as they occur. Compensation expense is recognized in the Company’s consolidated statements of operations and comprehensive loss, primarily within research and development expenses. For awards with only service conditions that have a graded vesting schedule, the Company recognizes compensation cost on a straight-line basis over the requisite service period for the entire award. For awards with market or performance conditions that have a graded vesting schedule, the Company recognizes compensation cost on a straight-line basis over the requisite service period for each tranche of the award.

Compensation expense resulting from performance awards is recognized over the requisite service period when it is probable that the performance condition will be met. The recognized compensation expense for performance awards is adjusted based on an estimate of awards ultimately expected to vest.

The Company estimates the fair value of service and performance-based options and SARs using a Black-Scholes option pricing model that uses assumptions including expected volatility, expected term, and the expected risk-free rate of return. The Company estimates the fair value of market-based RSUs using the Monte Carlo simulation model that uses assumptions including expected volatility, and the derived service period. The Company uses peer data to determine expected volatility and expected term. The Company estimates the fair value of RSUs based on the closing market price of its common stock on the date of measurement.

Recently Adopted and Issued Accounting Pronouncements

There are no recently adopted or issued accounting pronouncements that are expected to have a material impact on the Company.

Note 3 — Reverse Recapitalization

On February 8, 2023, Legacy LanzaTech and AMCI consummated the merger contemplated by the Merger Agreement (see Note 1 - Description of the Business).

Immediately following the Business Combination, there were 196,222,737 shares of common stock outstanding with a par value of $0.0001. Additionally, there were outstanding warrants to purchase 12,574,200 shares of common stock.

The Business Combination was accounted for as a reverse recapitalization in accordance with US GAAP. Under this method, while AMCI was the legal acquirer, it has been treated as the “acquired” company for financial reporting purposes. Accordingly, the Business Combination was treated as the equivalent of pre-combination Legacy LanzaTech issuing stock for the net assets of AMCI, accompanied by a recapitalization. The net assets of AMCI were stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination are those of pre-combination Legacy LanzaTech. Reported shares and earnings per share available to holders of the Company’s common stock and preferred shares, prior to the Business Combination, have been retroactively restated to reflect the exchange ratio established in the Business Combination (approximately one pre-combination Legacy LanzaTech share to 4.3747 of the Company’s shares).

Upon closing of the Business Combination, the shareholders of AMCI, including AMCI founders, were issued 10,398,374 shares of common stock of the Company. In connection with the closing, holders of 8,351,626 shares of common stock of AMCI were redeemed at a price per share of approximately $10.16. In connection with the Closing, 18,500,000 shares of common stock of the Company were issued to PIPE investors. 15,500,000 of those shares were issued at a price per share of $10.00. The remaining 3,000,000 shares were issued upon conversion of the AM SAFE liability. The Company incurred $7,223 in transaction costs relating to the Business Combination and recorded those costs against additional paid-in capital in the condensed consolidated balance sheet.

The number of shares of Class A common stock issued and outstanding immediately following the consummation of the Business Combination and PIPE financing were:


	Shares	Percentage
Legacy LanzaTech shares	167,324,363	85.3	%
Public stockholders	10,398,374	5.3	%
PIPE shares	18,500,000	9.4	%
Total	196,222,737	100	%

The following table reconciles the elements of the Business Combination and PIPE financing to the condensed consolidated statement of cash flows:


	Recapitalization
Cash - AMCI trust account1	$	64,090
Cash - PIPE financing	155,000
Less: Transaction costs allocated to equity	(5,709)
Effect of the Business Combination and PIPE financing	$	213,381

__________________

(1)The cash from the AMCI trust account is net of redemptions and the payment of pre-combination AMCI expenses.

The following table reconciles the elements of the Business Combination and PIPE financing to the change in additional paid-in capital on the condensed consolidated statement of changes in redeemable convertible preferred stock and shareholders’ equity / deficit:


	Recapitalization
Cash - AMCI trust account	$	64,090
Public Warrants and Private Placement Warrants recorded on the Closing Date	(4,624)
Cash - PIPE financing	155,000
Conversion of the AM SAFE	29,730
Transaction costs allocated to equity	(7,223)
	$	236,973
Less: par value of shares held by PIPE investors and public stockholders	(3)
Total additional paid-in capital from recapitalization	$	236,970

Note 4 — Net Loss Per Share

Basic net loss per share is computed by dividing net loss by the weighted-average number of shares of common stock of the Company outstanding during the period. Diluted net loss per share is computed by giving effect to all common stock equivalents of the Company, including equity-classified share-based compensation, the Brookfield SAFE, warrants, and contingently redeemable preferred stock, to the extent dilutive. Earnings per share calculation for all periods prior to the Business Combination have been retrospectively restated to the equivalent number of shares reflecting the exchange ratio established in the Merger Agreement of 4.3747.

The following table presents the calculation of basic and diluted net loss per share for the Company’s common stock (in thousands, except shares and per share amounts):


	Three Months Ended September 30,				Nine Months Ended September 30,

__________________

(1)In periods in which the Company reports a net loss, all common stock equivalents are excluded from the calculation of diluted weighted average shares outstanding because of their anti-dilutive effect on loss per share.

As of September 30, 2023 and 2022, common stock equivalents not included in the computation of loss per share because their effect would be antidilutive include the following:


	September 30,
	2023	2022
Redeemable convertible preferred stock (if converted)	—	129,148,393
Options	17,021,827	16,584,305

Brookfield SAFE	5,000,000	—
Warrants	16,657,686	985,278
Total	45,722,414	149,253,801

The preferred shares automatically converted into common shares upon the Business Combination at a 1:1 ratio. On February 8, 2023, upon conversion of the preferred shares, the cumulative accrued, declared and unpaid dividends on the preferred shares became payable. The total amount of cumulative accrued, undeclared and unpaid dividends was approximately $241,529 on the Closing Date. As stipulated by the Merger Agreement, this amount was divided by 10 and resulted in the issuance of an additional 24,152,942 common shares. Prior to the Business Combination, the additional 129,148,393 of common stock equivalents resulting from any such conversion are not included in the computation of diluted net loss per share because doing so would be anti-dilutive.

In connection with the AM SAFE and Brookfield SAFE, see Note 9 - Fair Value, the Company could issue additional potential shares of common stock. Shares related to the AM SAFE were issued on the Closing Date.

Shares related to the Brookfield SAFE and AM SAFE warrant have not been issued as of September 30, 2023. The terms of the AM SAFE warrant became exercisable for a fixed number of shares as of the Closing Date, see Note 7 – Warrants. As a result, these common stock equivalents are included in the warrants line item in the potential share table above as of September 30, 2023. The per share issuance price for the Brookfield SAFE upon closing of the Business Combination is the liquidity price as defined in the Brookfield SAFE agreement. As a result of the Business Combination, the Brookfield SAFE became convertible into a maximum number of shares, which is included in the table above as of September 30, 2023. None of these common stock equivalents are included in the computation of diluted net loss per share until actually issued because doing so would be anti-dilutive.

Contract balances

The following table provides changes in contract assets and liabilities (in thousands):


	Current Contract Assets		Current Contract Liabilities		Non-current Contract Liabilities
Balance as of January 1, 2023	$	18,000	$	3,101	$	10,760
Additions to unbilled accounts receivable	43,901		—		—
Increases due to cash received	—		4,486		—
Unbilled accounts receivable recognized in trade receivables	(37,413)		—		—

Reclassification from long-term to short-term	—		2,016		(2,016)
Reclassification to revenue as a result of performance obligations satisfied	—		(6,471)		—
Balance as of September 30, 2023	$	24,313	$	3,132	$	8,671

The increase in contract assets was mostly due to unbilled accounts receivable resulting from revenue recorded under contracts with customers where the Company performed engineering and other services, while the decrease in contract liabilities was primarily due to the recognition of revenue during the period related to advance payments previously received by the Company for engineering and other services contracts with customers. As of September 30, 2023 and December 31, 2022 the Company had $10,085 and $11,695, respectively, of billed accounts receivable, net of allowance.

The contract liability balance comprises unconditional payments received from the Company’s customers prior to the satisfaction of the related performance obligations. Such amounts are anticipated to be recorded as revenues when services are performed in subsequent periods. The Company expects to recognize the amounts classified as current contract liabilities in revenue within one year or less and those classified as non-current within two to three years.

Remaining performance obligations

Transaction price allocated to the remaining performance obligations represents contracted revenue that has not yet been recognized, which includes unearned revenue that will be recognized as revenue in future periods. Transaction price allocated to remaining performance obligations is influenced by several factors, including the length of the contract term compared to the research term and the existence of customer specific acceptance rights.

Remaining performance obligations consisted of the following (in thousands):


	As of
	September 30, 2023		December 31, 2022
Current	$	3,132	$	3,101
Non-current	8,671		10,760

The Company regularly reviews held-to-maturity securities for declines in fair values that are determined to be credit related. As of September 30, 2023, the Company did not have an allowance for credit losses related to held-to-maturity securities.

Equity investments

The Company’s equity investments consisted of the following (in thousands):


	As of
	September 30, 2023		December 31, 2022
Equity Method Investment in LanzaJet	$	9,594	$	10,561

LanzaJet

On May 13, 2020, the Company contributed $15,000 in intellectual property in exchange for a 37.5% interest (“Original Interest”) of LanzaJet, Inc. (“LanzaJet”) in connection with an investment agreement (“Investment Agreement”). The Company accounts for the transaction as a revenue transaction with a customer under ASC 606. The licensing and technical support services provided are recognized as a single combined performance obligation satisfied over the expected period of those services, beginning May 2020 through December 2025. During the three months ended September 30, 2023 and 2022, the Company recognized revenue from this arrangement of $565 and $540 respectively, net of intra-entity profit elimination. During the nine months ended September 30, 2023 and September 30, 2022, the Company recognized revenue from this arrangement of $1,701 and $1,620 respectively, net of intra-entity profit elimination and has associated deferred revenue of $6,047 and $8,062, as of September 30, 2023 and December 31, 2022, respectively. Intra-entity profits related to revenue contracts with LanzaJet are $107 and $132 for the three months ended September 30, 2023, and 2022, respectively. Intra-entity profits related to revenue contracts with LanzaJet are $313 and $395 for the nine months ended September 30, 2023 and 2022, respectively. Intra-entity profits are amortized over a 15-year period through 2034.

Between February 1, 2021 and April 4, 2021, LanzaJet closed two additional rounds of investment which reduced the Company's Original Interest to approximately 25%. In connection with the LanzaJet Note Purchase Agreement as described in Note 12 - Related Party Transactions, LanzaJet issued warrants that are exercisable for $0.01 by the holder when the related funds are drawn by LanzaJet. The warrants held by LanzaTech and other

lenders meet the accounting criteria for in-substance common stock at the time the related note commitment is drawn by LanzaJet and the warrants become exercisable. As of September 30, 2023, LanzaTech’s ownership was diluted to approximately 23.15% because LanzaTech received proportionally fewer warrants than the other investors. The Company recorded a gain on dilution of $502. LanzaTech’s ownership is subject to further dilution to approximately 22.38% if LanzaJet draws additional funds committed in the LanzaJet Note Purchase Agreement and the remaining warrants are exercisable by the holders. The Company retained its contingent right to receive additional interest in LanzaJet of up to 45 million shares for no additional consideration.

The carrying value of our equity method investment in LanzaJet as of September 30, 2023 and December 31, 2022 was approximately $2,200 and $3,700 less than our proportionate share of our equity method investees’ book values, respectively. The basis differences are largely the result of a difference in the timing of recognition of variable consideration to which we may become entitled in exchange for our contribution of intellectual property to LanzaJet. The variable consideration we may receive will be in the form of additional ownership interests and the majority of the basis difference will reverse in connection with recognition of that variable consideration.

In connection with a sublicense agreement to LanzaJet under our license agreement with Battelle Memorial Institute (“Battelle”), LanzaTech remains responsible for any failure by LanzaJet to pay royalties due to Battelle. The fair value of LanzaTech’s obligation under this guarantee was immaterial as of September 30, 2023 and December 31, 2022.

SGLT

On September 28, 2011, the Company contributed RMB 25,800 (approx. $4,000) in intellectual property in exchange for 30% of the registered capital of Beijing Shougang LanzaTech Technology Co., LTD (“SGLT”).

As of December 31, 2022, the Company’s interest in SGLT’s registered capital is approximately 9.31% as a result of the admittance of new investors during the year. As of September 30, 2022, the Company no longer had significant influence over the operating and financial policies of SGLT due to the significant and sustained decrease in SGLT's technological dependence on LanzaTech. As such, the Company ceased applying the equity method and from October 1, 2022 and forward, the Company accounts for its investment in equity security of SGLT using the alternative measurement principals as permitted under ASC 321, Investments - Equity Securities, because SGLT's fair value is not readily determinable. For the three and nine months ended September 30, 2023, there was no change in the value of the investment in SGLT.

As of September 30, 2023 and December 31, 2022, there were no impairments of equity investments. During the three months and nine months ended September 30, 2023 and 2022, the Company received no dividends from equity investments. See Note 12 - Related Party Transactions, for information on revenues, accounts receivable, contract assets and purchases and open accounts payable with its equity investments.

Note 7 — Warrants

Warrants on preferred shares

The Company had issued warrants to purchase its preferred shares representing 985,278 preferred shares. In connection with the closing of the Business Combination, all warrants were exercised on a cashless basis and are no longer outstanding. The warrants were exercised for 594,309 shares of preferred stock, which were converted at the closing of the Business Combination into shares of common stock. The exercise prices of the warrants ranged from $3.36 to $4.56 as of the closing of the Business Combination.

The warrants were accounted for as liabilities in accordance with ASC 480, and were presented within warrants on the condensed consolidated balance sheet as of December 31, 2022. The warrant liabilities were measured at fair value at inception and on a recurring basis, with changes in fair value presented within other expense, net on the condensed consolidated statements of operations and comprehensive loss. Immediately before the exercise of these warrants, the associated warrant liability was marked-to-market a final time to $5,890, which is equal to the number of shares issued multiplied by the share price of $9.91 on the date of exercise, February 8, 2023.

AM SAFE warrant

The warrant related to the AM SAFE (“AM SAFE warrant”) was accounted for as a liability in accordance with ASC 480 prior to the consummation of the Business Combination and was presented within warrants on the condensed consolidated balance sheet as of December 31, 2022. As a result of the Business Combination and issuance of the PIPE shares, the number of common shares available under the AM SAFE warrant equals 300,000. The exercise price of the AM SAFE warrant is $10.00 per share as determined on the Closing Date. The AM SAFE warrant expires at the earliest of (a) the fifth anniversary of the Business Combination, (b) the consummation of a dissolution event and (c) a change of control. Due to the AM SAFE warrant becoming exercisable for a fixed number of shares at a fixed exercise price, it no longer meets the criteria for liability accounting under ASC 480 and meets the criteria for equity classification under ASC 815-40. As a result, on the Closing Date, the AM SAFE warrant was marked-to-market a final time to $1,800 through other expense, net on the condensed consolidated statement of operations and comprehensive loss and reclassified to additional paid-in capital on the condensed consolidated balance sheet.

Shortfall Warrants

On March 27, 2023, the Company issued an aggregate of 2,073,486 warrants to ACM and 2,010,000 warrants to Vellar pursuant to the Forward Purchase Agreement (collectively, the “Shortfall Warrants”), as further described in Note 2 - Summary of Significant Accounting Policies. Each Shortfall Warrant entitles the registered holder to purchase one share of common stock at a price of $10.00 per share, subject to adjustment in the event that the Company sells, grants or otherwise issues common stock or common stock equivalents at an effective price less than the then current exercise price of the Shortfall Warrants, at any time commencing on or after March 27, 2023. The Shortfall Warrants expire on the fifth anniversary of their issuance. On the issuance date, the Shortfall Warrants met the definition of a derivative but did not qualify for the exception from derivative accounting under the indexation guidance and therefore met the criteria for liability classification under ASC 815. On May 13, 2023, the Company amended the Shortfall Warrant agreement. Under the amended agreement, the Shortfall Warrants meet the requirements for equity classification under ASC 815-40. Consequently, the Company recorded a gain of $2,042 as of the date of the amendment to reflect the fair value of $3,063 at the date of the amendment through other expense, net on the condensed consolidated statements of operations and comprehensive loss and reclassified the Shortfall Warrants to additional paid-in capital on the condensed consolidated balance sheet.

Public Warrants and Private Placement Warrants

As part of AMCI’s initial public offering (“IPO”), AMCI issued warrants to third-party investors where each whole warrant entitles the holder to purchase one share of the Company’s common stock at an exercise price of $11.50 per share (the “Public Warrants”). Simultaneously with the closing of the IPO, AMCI completed the private sale of warrants where each warrant allows the holder to purchase one share of the Company’s common stock at $11.50 per share. Additionally, prior to the consummation of the Business Combination, AMCI issued warrants for the settlement of a working capital loan. The working capital warrants have the same terms as the private sale of warrants issued at the IPO. Warrants sold in the private sale at the IPO and the warrants issued to convert the working capital loan are collectively referred to as the “Private Placement Warrants”. On the Closing Date and as of September 30, 2023, 7,499,924 Public Warrants and 4,774,276 Private Placement Warrants remained outstanding.

These warrants expire on the fifth anniversary of the Business Combination or earlier upon redemption or liquidation and are exercisable commencing 30 days after the Business Combination, provided that the Company has an effective registration statement under the Securities Act covering the shares of common stock issuable upon exercise of the warrants and a current prospectus relating to them is available (or the Company permits holders to exercise their warrants on a cashless basis under the circumstances specified in the warrant agreement) and registered, qualified or exempt from registration under the securities, or blue sky, laws of the state of residence of the holder.

Once the warrants become exercisable, the Company may redeem the outstanding warrants:

a.in whole and not in part;

b.at a price of $0.01 per warrant;

c.upon a minimum of 30 days’ prior written notice of redemption to each warrant holder; and

d.if, and only if, the closing price of the common stock equals or exceeds $18.00 per share for any 20 trading days within a 30-trading day period ending three trading days before we send the notice of redemption to the warrant holders.

The Public Warrants and Private Placement Warrants are recognized as derivative liabilities in accordance with ASC 815. Accordingly, the Company recognized the warrant instruments as liabilities at fair value as of the Closing Date, with an offsetting entry to additional paid-in capital and adjusts the carrying value of the instruments to fair value through other expense, net on the condensed consolidated statement of operations and comprehensive loss at each reporting period until they are exercised. As of September 30, 2023, the Public Warrants and Private Placement Warrants are presented within warrants on the condensed consolidated balance sheet.

Note 8 — Forward Purchase Agreement

As discussed in Note 2 - Summary of Significant Accounting Policies, the FPA consists of the prepaid forward contract and the Fixed Maturity Consideration. The prepaid forward contract is evaluated as an in-substance written put option that meets the definition of a derivative, referred to as the FPA Put Option in our condensed consolidated balance sheets. The value of the FPA Put Option represents the economics of the written put option, including the Variable Maturity Consideration and is valued at $38,092 as of September 30, 2023 .

The Fixed Maturity Consideration is valued at $7,020 as of September 30, 2023. This represents the fair value of the Share Consideration and Fixed Maturity Consideration and is measured in accordance with the FVO.

Expensed transaction costs, representing the stock acquisition fees, in the amount of $451 are recorded in other expense, net.

Note 9 — Fair Value

The following table presents the Company’s fair value hierarchy for its assets and liabilities measured at fair value as of September 30, 2023 and December 31, 2022 (in thousands):

Forward Purchase Agreement

The fair value upon issuance of the FPA (both the FPA Put Option liability and Fixed Maturity Consideration) and the change in fair value from issuance to September 30, 2023 net of the Prepayment Amount, is included in other expense, net in the condensed consolidated statements of operations and comprehensive loss. The fair value of the FPA was estimated using a Monte-Carlo Simulation in a risk-neutral framework. Specifically, the future stock price is simulated assuming a Geometric Brownian Motion (“GBM”). For each simulated path, the forward purchase value is calculated based on the contractual terms and then discounted back to present. Finally, the value of the forward is calculated as the average present value over all simulated paths. The Fixed Maturity Consideration was

also valued as part of this model as the timing of the payment of the Fixed Maturity Consideration may be accelerated if the Maturity Date is accelerated.

The following table represents the weighted average inputs used in calculating the fair value of the prepaid forward contract and the Fixed Maturity Consideration as of September 30, 2023:


	September 30, 2023
Stock price	$	4.67
Term (in years)	2.36
Expected volatility	50.0		%
Risk-free interest rate	4.89		%
Expected dividend yield	—		%

Warrants on preferred shares

The fair value of the warrants on preferred shares was estimated using a Black-Scholes option pricing model. Since the warrants were exercised on February 8, 2023 (see Note 7 - Warrants, for a description of the valuation on that date), the following table represents the weighted average inputs used in calculating the fair value of the preferred share warrants outstanding as of December 31, 2022:

Shortfall Warrants

The fair value of the Shortfall Warrants was estimated using a Black-Scholes option pricing model. The following table represents the weighted average inputs used in calculating the fair value of the Shortfall Warrants as of May 13, 2023 when the Shortfall Warrant Agreement was amended and the Shortfall Warrants were marked-to-market and reclassified to additional paid-in capital on the condensed consolidated balance sheet:


	May 13, 2023
Stock price	$	3.42

SAFE Liabilities and AM SAFE Warrant

The change in fair value between reporting periods for the Brookfield SAFE liability is included in other expense, net in the condensed consolidated statements of operations and comprehensive loss for the three and nine months ended September 30, 2023. The change in fair value between December 31, 2022 and the Closing Date for the AM SAFE liability is included in other expense, net in the condensed consolidated statements of operations and comprehensive loss for the nine months ended September 30, 2023. See below for further details on the AM SAFE liability and see Note 7 - Warrants for further details on the AM SAFE warrant.

The Company’s AM SAFE liability (until conversion to shares on the Closing Date), AM SAFE warrant (until conversion to an equity classified warrant on the Closing Date) and Brookfield SAFE liability are mark-to-market liabilities and are classified within Level 3 of the fair value hierarchy as the Company is using a scenario-based approach which allowed the Company to estimate the implied value of the business based on the terms of the SAFE. Significant unobservable inputs included probability and expected term. Probability was based upon the likelihood of the Company closing a transaction with a special purpose acquisition company. The expected term was based on the anticipated time until the SAFE investments would have a conversion event.

At conversion on the Closing Date, the AM SAFE liability converted into 3,000,000 shares of common stock. As of the Closing Date, the AM SAFE had a fair value of $29,730, which equals the closing price of approximately $9.91 on the Closing Date, multiplied by the number of shares issued. The AM SAFE was adjusted to its fair value on the Closing Date prior to settlement.

As of December 31, 2022, the AM SAFE had a fair value of $28,986 and was recorded within current liabilities on the condensed consolidated balance sheet. Significant inputs for Level 3 AM SAFE liability fair value measurement at December 31, 2022 are as follows:


	Near Term		Long-Term
Key assumptions:
Probability weighting	61	%	39	%
Time to conversion (in years)	0.1		0.8
Liquidity price	100	%	90	%
Discount rate	24.7	%	24.7	%

At conversion to equity classification on February 8, 2023, the AM SAFE warrant was valued using a Black-Scholes option pricing model as the warrant became exercisable for a fixed number of shares at a fixed price as described in Note 7 - Warrants. The following table represents the weighted average inputs used in calculating the fair value of the preferred share warrants outstanding at conversion to equity on February 8, 2023:


	February 8, 2023
Stock price	$	9.91

Significant inputs for Level 3 Brookfield SAFE liability fair value measurement at December 31, 2022 are the timing and likelihood of project financings under the Brookfield Framework Agreement. The Brookfield SAFE is legal form debt that the Company has elected to measure using the FVO under ASC 825. As of September 30, 2023, no part of the Brookfield SAFE has converted to Company common shares as a qualifying financing had not yet occurred and no project investments were presented. There were no cash flows associated with the Brookfield SAFE in the nine months ended September 30, 2023.

As of its issuance date, the fair value of the Brookfield SAFE is equal to the investment amount of $50,000 based on the orderly nature of the transaction. The value as of December 31, 2022 remains the same due to the proximity of the valuation date to the issuance date (i.e., less than two months) and the absence of events which would indicate a change in expected payoffs to the investor. As of December 31, 2022 the same expectations about sufficient projects meeting the agreed-upon investment criteria pursuant to the Brookfield Framework Agreement are maintained. As such the Brookfield SAFE’s fair value is estimated to be $50,000, as of December 31, 2022.

As of September 30, 2023, the Company expects to present sufficient projects to Brookfield to result in the Brookfield SAFE being automatically converted into shares. Since the liquidity price is not expected to change during the life of the Brookfield SAFE, the number of shares that Brookfield receives is fixed. Based on this expectation, the value of the Brookfield SAFE is equal to the Brookfield SAFE's as-converted value, which is the initial purchase amount, divided by the liquidity price, times the stock price, resulting in an estimated fair value of $23,350 recorded on the condensed consolidated balance sheet.

Significant inputs for Level 3 Brookfield SAFE measurement at September 30, 2023 are as follows:


	September 30, 2023
Initial purchase amount	$	50,000
Liquidity price	$	10.00
Stock price	$	4.67

Public Warrants and Private Placement Warrants

For the Public Warrants, the Company uses inputs such as actual trade data, quoted market prices from dealers or brokers, and other similar sources to determine the fair value and recognized an increase in the fair value of the liability of approximately $2,100 on the condensed consolidated statements of operations and comprehensive loss within other expense, net representing the change in fair value from the Closing Date to September 30, 2023.

The fair value of the Private Placement Warrants was estimated using a Black-Scholes option pricing model. For the nine months ended September 30, 2023, the Company recognized an increase in the fair value of liabilities of approximately $2,912 on the condensed consolidated statements of operations and comprehensive loss within other expense, net representing the change in fair value from the Closing Date to September 30, 2023.

The following table represents the weighted average inputs used in calculating the fair value of the Private Placement Warrants outstanding as of September 30, 2023 and at the time of the Business Combination:


	September 30, 2023
Stock price	$	4.67
Exercise price	$	11.50

Note 10 — Income Taxes

The Company is subject to federal and state income taxes in the United States, as well as income taxes in foreign jurisdictions in which it conducts business. The Company does not provide for federal income taxes on the undistributed earnings of its foreign subsidiaries as such earnings are reinvested indefinitely. The Company and its foreign subsidiaries have historically been loss generating entities that have resulted in no excess earnings to consider for repatriation and accordingly there are no deferred income taxes recognized for the three and nine months ended September 30, 2023 and 2022.

The Company recorded an income tax expense of $0 for the three and nine months ended September 30, 2023 and 2022, representing an effective tax rate of 0%. The difference between the U.S. federal statutory rate of 21% and the Company's effective tax rate in the three and nine months ended September 30, 2023 and 2022 is primarily due to a full valuation allowance related to the Company's U.S. and foreign deferred tax assets. The Company reassesses the need for a valuation allowance on a quarterly basis. If it is determined that a portion or all of the valuation

allowance is not required, it will generally be a benefit to the income tax provision in the period such determination is made.

The Company conducts business in multiple jurisdictions within and outside the United States. Consequently, the Company is subject to periodic income tax examinations by domestic and foreign income tax authorities. The Company is subject to audits for tax years 2017 and onward for federal purposes. There are tax years which remain subject to examination in various other state and foreign jurisdictions that are not material to the Company's financial statements.

Note 11 — Share-Based Compensation

The Company adopted the LanzaTech 2023 Long-Term Incentive Plan (the “LTIP”) in conjunction with the closing of the Business Combination. The LTIP provides for grants of a variety of awards to employees, directors, and other service providers to the Company, including, but not limited to stock options, stock appreciation rights, restricted stock awards, restricted stock units, performance awards and other stock-based awards or cash incentives. Prior to the effective date of the closing of the Business Combination, the Company granted awards under the LanzaTech NZ Inc. 2013 Stock Plan, the LanzaTech NZ Inc. 2015 Stock Plan, and the LanzaTech NZ, Inc. 2019 Stock Plan, (collectively, the “Prior Stock Plans”).

Equity Classified Awards:

RSUs

Under the LTIP, the Company has granted two types of RSUs: time-based RSUs, and market-based RSUs. Time-based RSUs granted to employees and other service providers (other than directors) are generally subject to a three-year annual pro-rata vesting schedule whereby the awards generally vest in 3 equal tranches on the first, second, and third anniversaries of the vesting commencement date, subject to grantee’s continued service through each vesting date. However, vesting will accelerate in certain circumstances (e.g., retirement, death, disability, or a qualified termination in connection with a change in control). Time-based RSUs granted to directors are subject to a one-year vesting schedule and the full award vests on the first anniversary of the vesting commencement date, subject to the director’s continued service through the vesting date. However, vesting will accelerate in certain circumstances (e.g., removal in connection with a change in control).

The market-based RSUs have both a time-based and a market-based vesting component. Both components must be met for the award to vest. The market-based RSUs are subject to the same three-year annual pro-rata vesting schedule as the employee time-based RSUs. The market-based vesting component is satisfied if on any date during the period beginning on the 151st date following the vesting commencement date and ending on the fifth anniversary of the vesting commencement date, the average closing price of a share of the Company’s common stock, equals or exceeds $11.50, determined using the closing share price from the 20 trading days preceding such determination date.

A summary of the unvested time-based and market-based equity-classified RSUs are presented in the following table:


	Number of RSUs (thousands)		Weighted Average Grant Date Fair Value
	Time-based	Market-based
January 1, 2023	—	—	$	—
Granted	3,143	3,930	2.49
Vested	(2)	—	3.45
Cancelled/forfeited	(28)	—	3.43
September 30, 2023	3,113	3,930	$	2.49

The Company recorded compensation expense related to the RSUs of $1,895 and $4,594 for the three and nine months ended September 30, 2023. Unrecognized compensation costs as of September 30, 2023 was $12,936 and will be recognized over a weighted average of 1.98 years.

Stock Options

In accordance with the LTIP and Prior Stock Plans, grantees have also been granted stock options to purchase common shares. The exercise prices of each stock option was no less than the fair market value price of the Company’s common shares determined as of the date of grant. The stock options generally vest over the course of two to five years, subject to the service provider’s continued service through each vesting date. Upon termination of service, unvested stock options are forfeited in accordance with their terms unless the award agreement provides for accelerated vesting (e.g., due to retirement). The below table reflects the stock options granted prior to the Business Combination multiplied by the exchange ratio and the weighted average exercise price divided by the exchange ratio.

Stock option awards outstanding as of September 30, 2023 and changes during the period ended September 30, 2023 were as follows:


	Shares subject to option (thousands)	Weighted average exercise price		Weighted average remaining contractual term (years)	Aggregate intrinsic value (thousands)
Outstanding at January 1, 2023	14,661	$	1.48	5.80
Vested and expecting to vest at January 1, 2023	14,661	1.48		5.80
Exercisable at January 1, 2023	11,203	$	1.44	5.15
Granted	3,556	3.77		—
Exercised	(1,075)	1.53		—
Cancelled/forfeited	(120)	1.76		—
Outstanding at September 30, 2023	17,022	$	1.95	6.21	$	47,653
Vested and expecting to vest at September 30, 2023	17,022	1.95		6.21	47,653
Exercisable at September 30, 2023	11,208	$	1.48	4.98	$	36,026

The Company recorded compensation expense related to the options of $1,234 and $653 for the three months ended September 30, 2023 and 2022, respectively, and $4,443 and $2,067 for the nine months ended September 30, 2023 and 2022. Unrecognized compensation costs as of September 30, 2023 was $9,550 and will be recognized over a weighted average of 2.29 years.

Restricted Stock Awards (“RSAs”)

Under the Prior Stock Plans, the Company granted RSAs which become eligible to vest upon the satisfaction of a time-based service condition. However, in order to vest, a liquidity event, defined as acquisition, asset transfer, or initial listing, must occur within 10 years from the grant date. Upon a liquidity event, if the participant’s service has not terminated, the entire RSA award vests in full, whether or not previously eligible for vesting. If the participant’s service has terminated and they have satisfied the time-based service condition, the RSAs that are outstanding and eligible for vesting immediately vest in full upon liquidity event. The time-based service requirements of the RSAs have a maximum term of three years from the date of grant.

As of December 31, 2022, there were 2,535,825 outstanding unvested RSAs with a weighted average grant date fair value of $1.08. The Business Combination constituted a “liquidity event” which caused the vesting of all such outstanding, unvested RSAs. The vesting of the RSAs resulted in compensation expense of $0 and $2,741 for the three and nine months ended September 30, 2023, respectively. There was no compensation expense recorded in the comparable periods in 2022, because the Company concluded that the liquidity event performance condition was not probable of being satisfied at the time. In connection with the vesting of these RSAs, certain holders of the RSAs

surrendered 771,141 shares in a withhold to cover transaction to fund the payment of applicable tax withholding on their behalf by the Company. This resulted in a total cash payment of $7,650 by the Company to the Internal Revenue Service for the applicable tax withholding associated with this vesting event.

Liability-Classified Awards

Phantom RSUs

Under a phantom equity sub-plan of the LTIP, certain non-US employees of the Company were provided with Phantom RSUs that can only be settled in cash and are therefore recorded as a liability. The Phantom RSUs have a graded vesting schedule and vest in 3 equal tranches on the first, second, and third anniversaries of the vesting commencement date, subject to the employee meeting the requisite service requirements. Grantees are entitled to receive a cash payment equal to the fair market value of a share multiplied by the number of vested RSUs as of the applicable vesting date.

Phantom SARs

Under a phantom equity sub-plan of the LTIP, certain non-US employees of the company were provided with Phantom SARs that can only be settled in cash and are therefore recorded as a liability. The Phantom SARs have a graded vesting schedule and vest in three equal tranches on the first, second, and third anniversaries of the vesting commencement date, subject to the employee meeting the requisite service requirements. Phantom SARs expire 10 years after the grant date and entitle the grantee to receive a cash payment upon exercise of the award equal to the excess of the fair market value of a share on the date of exercise over the exercise price multiplied by the number of SARs exercised.

LanzaJet Note Purchase Agreement

On November 9, 2022, the Company and the other LanzaJet shareholders entered into a Note Purchase Agreement (the “Note Purchase Agreement”), pursuant to which LanzaJet Freedom Pines Fuels LLC (“FPF”), a wholly owned subsidiary of LanzaJet, will issue, from time to time, notes in an aggregate principal amount of up to $147.0 million (the “Notes”), comprised of approximately $113.5 million aggregate principal amount of 6.00% Senior Secured Notes maturing December 31, 2043 and $33.5 million aggregate principal amount of 6.00% Subordinated Secured Notes maturing December 31, 2043. The Company committed to purchase $5.5 million of Subordinated Secured Notes, which was funded on May 1, 2023. The Senior Secured Notes are secured by a security interest over substantially all assets of FPF, and both the Senior Secured Notes and the Subordinated Secured Notes are secured by a security interest over the intellectual property owned or in-licensed by LanzaJet.

Each purchaser of Notes under the Note Purchase Agreement also received a warrant for the right to purchase 575,000 shares of common stock of LanzaJet for each $10 million of Notes purchased by such purchaser for an exercise price of $0.01 per share. The warrants are exercisable when the related loan commitment is funded, and may be exercised until the earlier of the third anniversary following the date the holder’s loan commitment is fully funded, or the end of the availability period as defined in the Note Purchase Agreement if the commitment has not been fully funded. In the case of the Company, LanzaTech received warrants to purchase 316,250 shares of common stock of LanzaJet, which became exercisable by the Company when the note was funded on May 1, 2023. Upon funding of the Notes, the warrants meet the accounting criteria to be considered in-substance common stock, and are accounted for as part of the equity-method investment. Refer to Note 6 Investment.

The Note Purchase Agreement may be amended with the approval of holders of at least 66 2∕3% of the Notes, except with respect to certain rights that require approval of all holders to amend. Upon an event of default under the Note Purchase Agreement, each purchaser may accelerate the payment of its own Notes. Enforcement against the collateral securing the Notes requires the approval of certain holders as specified in the Notes.

SGLT

The Company supplies SGLT with certain water-soluble organic compounds required in the Company's proprietary gas fermentation process, small-size equipment and consulting services. As a result, for the three months ended September 30, 2023 and 2022, the Company recognized revenue of approximately $0 and $87, respectively. For the nine months ended September 30, 2023 and 2022, the Company recognized revenue of approximately $75 and $151, respectively. The Company also provided engineering services and incurred costs of $199 and $630 for the three months ended September 30, 2023 and 2022, respectively, and provided engineering services and incurred costs of $612 and $893 for the nine months ended September 30, 2023 and 2022, respectively.

Additionally, LanzaTech and SGLT entered into a license agreement in 2019, subsequently amended in August 2023, to provide SGLT with the right to sublicense the intellectual property that LanzaTech previously licensed to

SGLT. In exchange, the Company is entitled to receive fixed licensing consideration, calculated as a percentage of the maximum amount of royalties owed to SGLT from its sublicenses. For the three and nine months ended September 30, 2023, the Company recognized sublicensing revenue of $951 and $1,200, respectively. Prior to June 2023, the Company was only entitled to royalties from SGLT if SGLT received sublicense royalty payments. For the three and nine months ended September 30, 2022, the Company did not recognize any sublicensing revenue as no royalties were received by SGLT.

Note 13 — Redeemable, Convertible Preferred Stock

Prior to the Business Combination, the Company had six outstanding series of contingently redeemable convertible preferred stock. The dollar amounts and share counts in the table below are adjusted to reflect the impact of the exchange ratio on the shares authorized, shares issued and outstanding, and issue price. The authorized, issued and outstanding shares, issue price, and carrying value as of December 31, 2022 are as follows (in thousands, except share and per share amounts):


	Shares Authorized	Shares Issued and Outstanding	Issue Price	Carrying Amount
Series A	20,414,445	20,414,445	$0.40 - $0.90	$	12,230
Series B	7,582,934	7,582,934	2.37	18,000
Series C	18,613,084	18,121,698	3.36	60,850
Series D	44,946,572	44,452,681	4.56	188,402
Series E	22,678,139	22,678,139	5.23	118,076
Series F	15,898,496	15,898,496	5.23	83,073
	130,133,670	129,148,393		$	480,631

All redeemable, convertible preferred stock was converted into common shares on the Closing Date of the Business Combination on a 1:1 basis. Immediately before the conversion, all cumulative dividends were declared, totaling a dividend payable of $241,529. This dividend was paid in-kind and subsequently converted, as a result of the Business Combination, into an additional 24,152,942 common shares. After the in-kind dividend payment and the conversion, the former preferred shareholders held 153,895,644 common shares.

Prior to the Business Combination, redemption features of the preferred shares were not fixed and did not have a determinable price on fixed or determinable dates. As of December 31, 2022, the preferred shares were not currently redeemable, and it was not probable that the preferred shares would become redeemable, since it was uncertain whether or when circumstances exist that would constitute a deemed liquidation event. Accordingly, the Company did not adjust the carrying value of the preferred shares to their redemption values.

Note 14 — Commitments and Contingencies

Litigation

The Company may be involved in legal proceedings and exposed to potential claims in the normal course of business. As of September 30, 2023 and December 31, 2022, the Company does not have any reasonably possible or probable losses from such claims.

Commitments

In November 2022, the Company entered into a lease for real estate to expand its headquarters in Skokie, Illinois, commencing on May 1, 2024. As the lease has not commenced, it is not recorded on the condensed consolidated balance sheet. Total lease payments in 2024, 2025 and 2026 for this lease are expected to be $3,287.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with our interim condensed consolidated financial statements and the related notes included in Part I, Item 1 of this Quarterly Report, and our audited consolidated financial statements and related notes included in the Company’s Form 8-K/A filed with the Securities and Exchange Commission on March 28, 2023. This discussion and analysis may contain forward-looking statements based upon current beliefs, plans and expectations that involve risks, uncertainties, and assumptions, including, but not limited to, risks and uncertainties discussed under the heading ‘Cautionary Note on Forward-Looking Statements,’ in this Quarterly Report and in Part I, Item 1A “Risk Factors” included in our Annual Report on Form 10-K. In this section, unless otherwise indicated or the context otherwise requires, references in this section to “LanzaTech,” the “Company,” “we,” “us,” “our” and other similar terms refer to LanzaTech Global, Inc. and its consolidated subsidiaries, including LanzaTech NZ, Inc. and its consolidated subsidiaries subsequent to the Business Combination and LanzaTech NZ, Inc. and its consolidated subsidiaries prior to the Business Combination. References to “AMCI” refer to AMCI Acquisition Corp. II prior to the Business Combination.

Overview

We are a nature-based carbon refining company that develops technology to transform waste carbon into the chemical building blocks for consumer goods such as sustainable fuels, fabrics, and packaging that people use in their daily lives. Our customers leverage our proven proprietary gas fermentation technology platform to convert certain feedstock, including waste carbon gases, into sustainable fuels and chemicals such as ethanol. Today, we are focused on taking advantage of the many uses of ethanol while capitalizing on the growing preference among major companies for renewable products and environmentally-conscious manufacturing processes. We have also been developing the capabilities to produce single cell protein as a primary product from our gas fermentation platform.

LanzaTech performs research and development (“R&D”) services related to novel technologies and development of biocatalysts for commercial applications, mainly to produce fuels and chemicals. We primarily employ a licensing business model whereby our customers build, own and operate facilities that use our technology, and in return, we are paid a royalty fee based on the revenue generated from the use of our technology. We began operations in 2005. In 2018, through our joint venture in China (SGLT), we established the world’s first commercial waste gas-to-ethanol plant in China, followed by four more plants between 2021 and 2023 - three in China and one in India, with others currently in development in various countries around the world.

We have not achieved operating profitability since our formation. Our net losses after tax were $(25.3) million for the three months ended September 30, 2023 and $(22.3) million for the three months ended September 30, 2022. As of September 30, 2023 we had an accumulated deficit of $(813.2) million compared to an accumulated deficit of $(456.2) million as of December 31, 2022. We anticipate that we will continue to incur losses until we sufficiently commercialize our technology.

Near-term, we expect engineering services and sales of equipment packages on several key committed and contracted projects to drive higher revenues, along with our CarbonSmart business, which we expect to further improve on our 2022 performance, fueled by planned commercial campaigns from brand partners across many consumer product verticals. This increase in CarbonSmart revenue is also enabled by more plants coming online and LanzaTech securing offtake supply to place into our customers’ and partners’ CarbonSmart supply chains.

The Business Combination

On March 8, 2022, AMCI entered into the Merger Agreement with LanzaTech NZ, Inc. and AMCI Merger Sub, Inc. (“Merger Sub”). On February 8, 2023, Merger Sub merged with and into LanzaTech NZ, Inc. Upon consummation of the Business Combination, the separate corporate existence of Merger Sub ceased, and LanzaTech NZ, Inc. survived the Business Combination and became a wholly owned subsidiary of AMCI. In connection with the consummation of the Business Combination, the combined company was renamed “LanzaTech Global, Inc.”.

Accounting Impact of the Business Combination

The Business Combination was accounted for as a reverse recapitalization. LanzaTech NZ, Inc. was deemed the accounting predecessor and the Company is the successor SEC registrant.

Under this method of accounting, AMCI was treated as the acquired company for financial statement reporting purposes. For accounting purposes, LanzaTech NZ, Inc. was deemed to be the accounting acquirer in the transaction and, consequently, the transaction was treated as a recapitalization of LanzaTech NZ, Inc. (i.e., a capital transaction involving the issuance of stock by AMCI for the stock of LanzaTech NZ, Inc.). Accordingly, the consolidated balance sheets and results of operations of LanzaTech NZ, Inc. became the historical financial statements of the Company, and AMCI’s assets, liabilities and results of operations were consolidated with LanzaTech NZ Inc.’s beginning on the acquisition date. The net assets of AMCI were recognized at carrying value, with no goodwill or other intangible assets recorded.

Basis of Presentation

LanzaTech’s condensed consolidated financial statements were prepared in accordance with US GAAP. See Note 2 to our condensed consolidated financial statements for a full description of our basis of presentation.

Prior to filing our third quarter financial statements on Form 10-Q, we determined that our prior interpretation of the accounting guidance applicable to certain elements of the Forward Purchase Agreement (“FPA”) was incorrect. As a result, we have revised the accounting treatment of the FPA in our financial statements as of September 30, 2023 to reclassify the Prepayment Amount of $60.5 million, previously recorded as part of a net non-current derivative asset in the condensed consolidated balance sheet, to the equity section of the condensed consolidated balance sheet. The remaining liability balance of $38.1 million associated with the FPA, including the Minimum Maturity Consideration and the Share Consideration, are now reflected as non-current liabilities in our condensed consolidated balance sheet.

Key Operational and Business Metrics

In addition to the measures presented in our condensed consolidated financial statements, we review the following key business metrics to measure our performance, identify trends affecting our business, formulate business plans, and make strategic decisions that will impact the future operational results of LanzaTech. Increases or decreases in our key business metrics may not correspond with increases or decreases in our revenue.

Key Financial Metrics:

Capacity based on LanzaTech’s technology includes capacity by customers and our cost method investee, is one of the key drivers for the Company's licensing revenues given that they are usually contracted on a percentage-of-revenue, a dollars-per-tonne, or fixed-consideration basis.

Components of Operating Results

While we have offerings in multiple market segments and operate in multiple countries, we operate and manage our business as one reportable operating segment. Nearly all of our service offerings are delivered and supported on a global basis. Additionally, most of our service offerings are deployed in a similar way, and we evaluate our financial information and resources and assess the performance of these resources on a consolidated basis.

Revenues

We earn revenue through engineering and other services contracts, U.S. government contracts, joint development agreements, and licensing agreements, which, together, represent a single operating segment. Revenues can be viewed as a combination of the following:

•Biorefining which includes feasibility studies and engineering services related to basic design of commercial plants utilizing our technologies, and licensing of intellectual property and software when customers deploy our biorefining technology;

•Joint development and research services related to novel technologies and the development of biocatalysts; and

•Sale of CarbonSmart products to customers.

Revenue is measured based on the consideration specified in customer contracts and excludes amounts collected on behalf of third parties.

Biorefining

We provide feasibility studies and basic design and engineering services used for detailed design, procurement, and construction of commercial plants that utilize our technologies, along with the sale of equipment and microbes. The services provided are recognized as a performance obligation satisfied over time. Revenue is recognized using the output method based on milestone completion, the cost-to-cost input method for certain engineering services, or the percentage of completion method in accordance with Accounting Standards Codification (“ASC”) 606, Revenue

from Contracts with Customers (“ASC 606”). Revenue for the sale of microbes and media is recognized at a point in time, depending on when control transfers to the customer.

We license intellectual property to generate recurring revenue in the case of running royalties, or one-time revenue, in the case of fixed consideration royalties, when our customers deploy our technology in their biorefining plants. When licenses are considered to be distinct performance obligations, the recognition of revenue is dependent on the terms of the contract, which may include fixed consideration or royalties based on sales or usage, in which case, the revenue is recognized when the subsequent sale or usage occurs or when the performance obligation to which some or all of the sales or usage-based royalty is allocated or has been satisfied, whichever is later.

Joint Development and Contract Research

We perform R&D services related to novel technologies and the development of biocatalysts for commercial applications, mainly to produce fuels and chemicals. We engage in two main types of R&D services – joint development agreements, and other contract research, including projects with the U.S. Department of Energy. Such services are recognized as a performance obligation satisfied over time. Revenue is recognized based on milestone completion, when payments are contingent upon the achievement of such milestones, or based on stage of contract or phase completion method when enforceable rights to payment exist. When no milestones or stages are clearly defined, management has determined that the cost incurred, input method, is an appropriate measure of progress toward complete satisfaction of the performance obligations under ASC 606 and estimates its variable consideration under the expected value method.

Revenue is not recognized in advance of customer acceptance of a milestone, when such acceptance is contractually required. Payments for R&D services with no contractual payments are not due from customers until a technical report is submitted; therefore, a contract asset is recognized at milestone completion but prior to the submission of a technical report. The contract asset represents the Company’s right to consideration for the services performed at milestone completion. Occasionally, customers provide payments in advance of us providing services which creates a contract liability for the Company. The contract liability represents our obligation to provide services to a customer.

CarbonSmart

We sell CarbonSmart products and intermediaries directly to customers purchased from our licensed plants using the Company's proprietary technologies. Revenue is recognized at a point in time when control transfers to the customer, which varies depending on the shipping terms. We generally acts as the principal in such transactions and accordingly, recognizes revenue and cost of revenues on a gross basis.

Cost of Revenues

Our R&D costs associated with external projects, engineering, and other direct costs of services are related to revenue agreements with customers, related parties, and collaborative partners, and represent costs of revenue. Costs include both internal and third-party fixed and variable costs and include materials, supplies, labor, and fringe benefits.

Research and Development Expenses

R&D expenses consist of personnel costs and the cost of consultants, materials and supplies associated with internal R&D projects as well as various laboratory activities. Indirect R&D costs include depreciation and other indirect overhead expenses. We expect our R&D activities to increase in the future as revenue grows but decrease as a percentage of our overall cost structure.

Selling, General and Administrative Expenses

Selling, general and administrative expenses ("SG&A") consist primarily of personnel costs, costs of general corporate development activities, travel-related expenses, and other indirect overhead costs.

Our general and administrative expenses consist primarily of personnel costs for our executive, finance, corporate and other administrative functions, intellectual property and patent costs, facilities and other allocated expenses, other expenses for outside professional services, including legal, human resources, audit and accounting services, and insurance costs. We expect our general and administrative expenses to increase as a result of operating as a public company, including additional costs relating to compliance with the rules and regulations of the SEC and stock exchange rules, legal and audit services, additional insurance, investor relations activities, and other administrative and professional services. We also expect our intellectual property expenses to increase as we expand and increase protection of our intellectual property portfolio.

Other Expense, Net

Other expense, net relates to miscellaneous other income and expense and foreign currency gains and losses. These items include the mark-to-market adjustments on all liability classified warrants, the FPA Put Option liability, the Fixed Maturity Consideration, and SAFE liabilities. Interest income, net consists of income earned from our cash, cash equivalents and debt security investments. Our interest income has increased following the completion of the Business Combination as we invested the net proceeds in a variety of capital preservation financial instruments, including short and long-term, investment-grade, interest-bearing obligations of the U.S. government and its agencies.

Loss (Gain) from Equity Investees, Net

We hold interests in LanzaJet located in the United States, and the Shougang Joint Venture (also referred as “SGLT” herein) located in China which we have determined to be variable interest entities (“VIEs”) for which it has been determined we are not the primary beneficiary. Our variable interests primarily relate to entities in which we have a non-controlling equity interest. Although these financial arrangements resulted in holding variable interests in these entities, they do not empower us to direct the activities of the VIEs that most significantly impact the VIEs’ economic performance, therefore LanzaTech has determined it is not the primary beneficiary and does not currently consolidate these VIEs.

Through our holdings in LanzaJet, our representation on the board of directors and participation in the policy-making process, as well as the material intra-entity transactions, we have determined that we can exercise significant influence over the activities of LanzaJet. Our interest in LanzaJet is accounted for under the equity method of accounting, with income (loss) from equity method investees, net recognized in our consolidated statements of operations and comprehensive loss and equity method investments recognized on our consolidated balance sheets.

As of September 30, 2022, we no longer have significant influence over the activities of SGLT and as a result, our investment is accounted for at cost with adjustments for observable changes in price and impairment (if any) recognized in our consolidated statements of operations and comprehensive loss. Previously to September 30, 2022, we accounted for SGLT under the equity method of accounting, with income (loss) from equity method investees, net, including gain on dilution recognized in our consolidated statements of operations and comprehensive loss and equity method investments recognized on our consolidated balance sheet.

The Company currently has a license agreement with SGLT and a letter agreement with SGLT and Sinopec Capital Co., Ltd related to the use of our intellectual property and potential collaborations. These agreements do not provide LanzaTech with the power to direct the activities that are most significant to the economic performance of these entities.

Income Tax Expense

Current and deferred taxes are calculated based on tax rates enacted or substantively enacted at the reporting date and are recognized in profit or loss except when the tax relates to items charged or credited to other comprehensive income, in which case the tax is also recognized in other comprehensive income. Deferred tax is recognized in respect of temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the financial statements. Deferred tax assets including those relating to temporary differences, net operating loss carryforwards and tax credit carryforwards, are only recognized to the extent it is more likely than not that future taxable income will be available to utilize the temporary differences and carryforwards. Our net

operating loss carryforwards are subject to shareholder continuity rules, and may be impacted by future fundraising activities.

We maintain a valuation allowance against the full value of our net deferred tax assets because management believes the recoverability of the tax assets is not more likely than not.

Revenue

Total revenue increased $11.5 million, or 143%, in the three months ended September 30, 2023, compared to the same period in 2022. The increase was primarily driven by engineering and other services with an increase of $7.4 million in revenue from contracts with existing customers whose projects have moved to the next phase of development and an increase of $0.4 million from contracts with new customers. Additionally, we had a $1.0 million increase in licensing revenue, a $1.7 million increase in other contract research and a $0.4 million increase in revenue from joint development agreements. CarbonSmart products revenue increased $0.6 million in the three months ended September 30, 2023 compared to the same period in 2022.

Cost of Revenue

Cost of revenue increased $8.4 million, or 141%, in the three months ended September 30, 2023, compared to the same period in 2022. The increase is primarily driven by the higher revenue performance from engineering and other services, mostly from projects that moved to the next phase of development, and inflation in costs and wages.

Research and Development

R&D expense increased $2.4 million, or 17%, in the three months ended September 30, 2023 compared to the same period in 2022. This was primarily due to $1.2 million in incremental stock compensation expense associated with 2023 equity awards, an increase of $0.8 million in R&D personnel/contractors, external services and consumables expenses to accelerate growth, and an increase of $0.4 million for facilities expenses.

Selling, General and Administrative Expense

SG&A expense increased $4.6 million, or 63%, in the three months ended September 30, 2023 compared to the same period in 2022. This was primarily due to an increase of $2.6 million in SG&A external services and contractors driven by increases in professional services fees, board expenses, and business insurance, $1.6 million in incremental stock compensation expense associated with 2023 equity awards, an increase of $0.3 million in SG&A personnel expenses to support our growth, and an increase of $0.2 million in facilities expenses. The increase was offset by a recovery of bad debt of $(0.1) million.

Interest income, net

Interest income, net increased $1.2 million in the three months ended September 30, 2023 compared to the same period in 2022. The increase is primarily attributable to interest earned on higher cash balances held in savings and money market accounts subsequent to the Business Combination and the amortization of the discount on the held-to-maturity securities.

Other Expense, Net

Other expense, net increased $0.3 million, in the three months ended September 30, 2023 compared to the same period in 2022. The increase is primarily due to an overall net loss on changes in the fair value of our financial instruments.

Revenue

Total revenue increased $16.4 million, or 64%, in the nine months ended September 30, 2023 compared to the same period in 2022. The increase was primarily driven by engineering and other services with an increase of $11.4 million in revenue from contracts with existing customers whose projects have moved to the next phase of development and an increase of $1.5 million from contracts with new customers. Additionally, we had a $1.3 million increase in revenue from licensing, a $1.0 million increase in revenue from joint development agreements and $1.3 million in other contract research, partially offset by a decrease of $(0.1) million in CarbonSmart revenue.

Cost of Revenues

Cost of revenue increased $13.8 million, or 72%, in the nine months ended September 30, 2023 compared to the same period in 2022. The increase is primarily driven by the higher revenue performance from engineering and other services, mostly from projects that moved to the next phase of development, and inflation in costs and wages.

Research and Development

R&D expense increased $12.0 million, or 30%, in the nine months ended September 30, 2023 compared to the same period in 2022. This was primarily due to an increase of $5.4 million in R&D personnel/contractors and consumables expenses to accelerate growth, an increase in stock compensation expense consisting of $2.9 million in incremental expense associated with stock compensation granted in 2023 and $1.2 million resulting from the vesting of RSAs in connection with the Business Combination, an increase of $1.2 million in external R&D service provider costs, and an increase of $1.3 million in facilities expenses.

Selling, General and Administrative Expense

SG&A expense increased $21.6 million, or 111%, in the nine months ended September 30, 2023 compared to the same period in 2022. This was primarily due to an increase of $10.1 million of external services and contractors mostly driven by one-time professional services fees related to the Business Combination, as well as $3.9 million resulting from the vesting of RSAs and one-time employee transition arrangements related to the Business Combination. The increase is also attributed to $3.8 million in incremental expense associated with stock compensation granted in 2023, an increase of $2.6 million in personnel and consumables expenses to support our growth, an increase of $0.7 million related to an allowance for a customer receivable, and an increase of $0.5 million in facilities expenses.

Interest income, net

Interest income, net increased $3.2 million in the nine months ended September 30, 2023 compared to the same period in 2022. The increase is primarily attributable to interest earned on higher cash balances held in savings and money market accounts subsequent to the Business Combination. The increase is additionally attributable to the amortization of the discount and accrued interest on the held-to-maturity securities.

Other Expense, Net

Other expense, net increased $(28.8) million, in the nine months ended September 30, 2023 compared to the same period in 2022. The increase is primarily due to an overall net loss on changes in the fair value of our financial instruments.

Liquidity and Capital Resources

Cash and Cash Equivalents

Cash and cash equivalents comprise cash on hand, demand deposits at banks, and other short-term, highly liquid investments with original maturity of three months or less that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value. The following table shows the balances of our cash, cash equivalents and restricted cash as of September 30, 2023 and December 31, 2022:


	As of				Change
(In thousands, except for percentages)	September 30, 2023		December 31, 2022		2023 vs. 2022
Total cash, cash equivalents, and restricted cash	$	92,070	$	83,710	$	8,360	10	%

As of September 30, 2023, as compared to December 31, 2022, LanzaTech’s cash, cash equivalents, and restricted cash increased by $8.4 million, or 10%, primarily due to the closing of the Business Combination and PIPE financing, net of funding of the Forward Purchase Agreement. The increase was also partially offset by cash usage (see Cash flow section below) to fund working capital, the net loss adjusted for non-cash charges, purchase of debt security investments, purchases of property, plant and equipment and the repurchase of equity instruments of the Company.

Debt Security Investments

Debt security investments comprise held-to-maturity U.S. Treasury securities that the Company has both the ability and intent to hold to maturity. These securities all mature within thirteen months and will provide additional liquidity upon maturity. As of September 30, 2023, held-to-maturity security investments totaled $44.8 million. The Company did not have any held-to-maturity security investments as of December 31, 2022.

Sources and Uses of Capital

Since inception, we have financed our operations primarily through equity and debt financing.

Our ability to successfully develop products and expand our business depends on many factors, including our ability to meet working capital needs, the availability of equity or debt financing and, over time, our ability to generate cash flows from operations. We manage our capital to ensure that LanzaTech can continue as a going concern while maximizing the return to stakeholders through the optimization of debt and equity balances. Following completion of the Business Combination, the Company may change its capital risk strategy related to use of capital proceeds from the Business Combination to increase its product offerings or for business growth purposes.

As of September 30, 2023, our capital structure consists of equity (comprising issued capital, and accumulated deficit) and the Brookfield SAFE. We are not subject to any externally imposed capital requirements.

Prior to the Business Combination, LanzaTech had six outstanding series of redeemable preferred stock. LanzaTech preferred shares were convertible at the holder’s option into shares of common stock, on a share-for-share basis, using a conversion rate determined by dividing the original issue price by the conversion price. Each LanzaTech preferred share was automatically converted into a common share of LanzaTech on the Closing Date.

On October 2, 2022, LanzaTech entered into the Brookfield SAFE with Brookfield and received a cash payment of $50.0 million as the Initial Purchase Amount. In exchange, the Company granted to Brookfield the right to certain shares of the Company's common stock. Following the closing of the Business Combination, Brookfield may, at any time at its option, convert all or a portion of the Initial Purchase Amount less any amount that has already been converted or repaid into shares of common stock.

LanzaTech does not have any outstanding debt, other than the Brookfield SAFE and the Fixed Maturity Consideration, which are both classified as liabilities for accounting purposes, on its condensed consolidated balance sheet as of September 30, 2023.

On November 9, 2022, LanzaTech committed to purchase $5.5 million of Subordinated Secured Notes in a funding for LanzaJet's subsidiary Freedom Pines Fuels LLC, which occurred on May 1, 2023. The Subordinated Secured Notes are secured by a security interest over the intellectual property owned or in-licensed by LanzaJet. LanzaJet also provides a guarantee of any costs and expenses required to complete the initial facility and achieve commercial operation.

LanzaTech, AMCI and ACM executed the Forward Purchase Agreement on February 3, 2023. Pursuant to the Forward Purchase Agreement, ACM obtained 5,916,514 shares of common stock on the open market for $10.16 per share (“Redemption Price”), and such purchase price of $60.1 million was funded by the use of Trust Account proceeds as a prepayment (“Prepayment Amount”) for the Forward Purchase Agreement redemption at the end of three years (“Maturity Date”). ACM has the right at the end of three years to return the shares and keep the Prepayment Amount plus the fees described below, or may, at ACM’s sole discretion, partially or fully terminate this transaction over the course of the three-year term by returning cash in an amount equal to the number of shares terminated (“Terminated Shares”) multiplied by the Redemption Price, which may be reduced in the case of certain dilutive events (“Reset Price”). At the end of the three-year term, New LanzaTech is obligated to pay ACM an amount equal to the product of (1) 7,500,000 less (b) the number of Terminated Shares multiplied by (2) $2.00 (the “Maturity Consideration”). In addition to the Prepayment Amount and the Maturity Consideration, on the Maturity Date, New LanzaTech will pay to ACM an amount equal to the product of (x) 500,000 and (y) the Redemption Price, totaling $5.1 million (the “Share Consideration”). However, at the time, the Company may not have sufficient funds or be able to obtain financing from third parties to pay such amounts. The Company also may not have

sufficient shares authorized to pay the Maturity Consideration in shares. Breach by the Company of any of these obligations could constitute an event of default under the Forward Purchase Agreement, which could subject the Company to financial exposure thereunder (including arising from potential indemnification claims by the Seller). In addition, future debt or other contractual agreements may contain cross-default or cross-acceleration provisions that could be triggered if we defaulted on our obligations to the Purchasers. Any or all of these consequences could have material adverse impact on us.

On February 8, 2023, LanzaTech completed the Business Combination and related transactions. The completion of the Business Combination and related transactions resulted in $153.3 million of cash proceeds to LanzaTech. The amount released to LanzaTech is net of the transaction expenses related to the Business Combination and the amount paid to the Purchasers in relation to the Forward Purchase Agreement. Pursuant to the Forward Purchase Agreement, the Purchasers purchased 5,916,514 Class A common shares on the open market for approximately $10.16 per share, and such purchase price of $60.1 million was deposited with the Purchasers as a prepayment for the Forward Purchase Agreement redemption at the end of three years.

In the normal course of our business, we also enter into purchase commitments or other transactions in which we make representations and warranties that relate to the performance of our goods and services. We do not expect material losses related to these transactions.

We believe our existing cash and cash equivalents will be sufficient to fund our operations for at least the next 12 months from the date of this Quarterly Report. However, our liquidity assumptions may prove to be incorrect, and we could utilize our available financial resources sooner than we currently expect. Our future capital requirements and the adequacy of available funds will depend on many factors, including those set forth under “Risk Factors”.

If we determine that we require additional financing to meet our operating requirements, we may be unable to secure such financing on acceptable terms, or at all. If we raise additional funds by issuing equity and/or convertible debt securities, dilution to our existing stockholders will result. If we raise additional financing and incur indebtedness, we would be subject to increased fixed payment obligations and could also be subject to certain restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. If we are unable to obtain additional funds, we will have to reduce our operating costs, which will cause a delay or reduction in our technology development and commercialization programs.

Cash Flows Used in Operating Activities

For the nine months ended September 30, 2023, net cash used in operating activities was $(81.6) million. This was primarily driven by a net loss of $(115.4) million, adjusted for the loss on change in fair value of the FPA Put Option liability and Fixed Maturity Consideration of $44.7 million, share-based compensation expense of $11.9 million, depreciation of property, plant and equipment of $4.0 million, non-cash lease expense of $0.9 million, the non-cash loss from equity method investees, net of $0.9 million, and provision for losses on trade and other receivables of $0.7 million. The additional impact to net cash usage is related to the adjustments for net cash changes in operating assets and liabilities of $(12.8) million, the gain on change of fair value of SAFE and warrant liabilities of $(14.2) million, the non-cash recognition of licensing revenue of $(1.7) million, amortization of the discount on the debt security investment of $(0.9) million, and non-cash foreign currency exchange gain of $0.4 million.

For the nine months ended September 30, 2022, net cash used in operating activities was $(71.3) million. This was primarily driven by a net loss of $(55.0) million, adjusted for share-based compensation expense of $2.1 million, depreciation of property, plant and equipment of $3.4 million, the loss from equity method investees, net of $(2.3) million, non-cash lease expense of $1.3 million and non-cash foreign currency exchange loss of $1.3 million. The additional net cash usage is related to the adjustments for net cash changes in operating assets and liabilities of $(20.2) million, non-cash recognition of licensing revenue of $(1.6) million, and the gain on change in fair value of SAFE and warrant liabilities of $(0.3) million.

Cash Flows Used in Investing Activities

For the nine months ended September 30, 2023, net cash used in investing activities was $(116.6) million, driven by the investment in debt securities of $(93.9) million, the Forward Purchase Agreement prepayment amount of $(60.1) million, the purchase of property, plant and equipment of $(7.1) million, the funding of the loan commitment to LanzaJet of $(5.2) million, and the purchase of additional interests in our equity method investment in the form of warrants which were accounted as in-substance common stock of $(0.3) million, partially offset by $50 million of maturities from the investment in debt securities.

For the nine months ended September 30, 2022, net cash used in investing activities was $(6.5) million, driven by the purchase of property, plant and equipment.

Cash Flows from Financing Activities

For the nine months ended September 30, 2023, net cash provided by financing activities was $207.4 million. This was driven by $213.4 million in proceeds from the Business Combination, PIPE financing and the Forward Purchase Agreement and proceeds of $1.6 million from the exercise of options to acquire shares of common stock of the Company. This was partially offset by the repurchase of equity instruments of $(7.7) million.

For the nine months ended September 30, 2022, net cash provided by financing activities was not significant.

Off-Balance Sheet Arrangements

As of September 30, 2023 and December 31, 2022, we did not engage in any off-balance sheet arrangements, including the use of structured finance, special purpose entities or variable interest entities.

Critical Accounting Policies and Management Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our condensed consolidated financial statements that have been prepared in accordance with US GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosures. We consider an accounting estimate to be critical to the condensed consolidated financial statements if the estimate is complex in nature or requires a high degree of judgment and actual results may differ from these estimates with any such differences being potentially material. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances. We evaluate our estimates and assumptions on an ongoing basis. A discussion of our critical accounting policies and estimates may be found in the Company’s prospectus filed with the SEC on May 25,

2023 in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” under the heading “Critical Accounting Policies and Management Estimates”. There have been two changes to our critical accounting policies and estimates since the filing of the aforementioned prospectus that are discussed below:

Forward Purchase Agreement Valuation

The Company has determined that the FPA Put Option, including the Variable Maturity Consideration, within the Forward Purchase Agreement is (i) a freestanding financial instrument and (ii) a derivative (i.e., an in-substance written put option). This derivative, referred to throughout as the prepaid forward contract derivative was recorded as an asset at fair value on the condensed consolidated balance sheet as of the reporting date. The fair value of the derivative was estimated using a Monte-Carlo Simulation in a risk-neutral framework. Specifically, the future stock price is simulated assuming a Geometric Brownian Motion (“GBM”). For each simulated path, the forward purchase value is calculated based on the contractual terms and then discounted back to present. Finally, the value of the forward is calculated as the average present value over all simulated paths.

The Company separately identified two other freestanding financial instruments in the Forward Purchase Agreement, the Share Consideration and the Minimum Maturity Consideration. As both of these payments are for a fixed amount at the Maturity Date, we have accounted for these cash outflows as debt-like instruments. In accordance with ASC 825, Financial Instruments, we have elected to account for these instruments under the Fair Value Option. As the terms and conditions of these payments are the same, they are accounted for together on the condensed consolidated balance sheet as of September 30, 2023 as the Fixed Maturity Consideration. The fair value of the Fixed Maturity Consideration was estimated within the same Monte-Carlo simulation as the prepaid forward contract to effectively model the potential acceleration of the Maturity Date and the corresponding acceleration in the payment of the Fixed Maturity Consideration.

Stock-Based Compensation

The Company’s equity-based awards include stock option awards, restricted stock units (“RSUs”), stock-appreciation rights (“SARs”) and restricted stock (“RSAs”) issued by the Company, which vest based on either time and/or the achievement of certain market or performance conditions. We have elected not to estimate forfeitures which means compensation expenses may be reversed in the period in which the forfeiture occurs. Compensation expense is recognized in the Company’s consolidated statements of operations and comprehensive loss, primarily within research and development expenses. For awards with only service conditions that have a graded vesting schedule, the Company recognizes compensation cost on a straight-line basis over the requisite service period for the entire award. For awards with market or performance conditions that have a graded vesting schedule, the Company recognizes compensation cost on a straight-line basis over the requisite service period for each tranche of the award. Compensation expense resulting from performance awards is recognized over the requisite service period when it is probable that the performance condition will be met. The recognized compensation expense for performance awards is adjusted based on an estimate of awards ultimately expected to vest.

We mostly apply judgment for stock-based awards with performance conditions, because compensation expense is recognized only when it is probable the performance conditions will be met (i.e. occurrence of a liquidity event). Management determined that the occurrence of the liquidity event is probable when the event is consummated, as such, compensation expense related to the RSAs was recorded at the time of the Business Combination.

We estimate the fair value of service and performance-based options and SARs using a Black-Scholes option pricing model, which requires the use of highly subjective assumptions including:

•Expected Term — We have opted to use the “simplified method” for estimating the expected term of plain-vanilla options and SARs, whereby the expected term equals the arithmetic average of the vesting term and

LanzaTech’s contractual term of the option (generally 10 years). We use peer data to estimate the expected term of options and SARs that do not have plain-vanilla characteristics.

•Risk-Free Interest Rate — The risk-free rate assumption is based on the U.S. Treasury zero-coupon instruments with maturities similar to the expected term of LanzaTech’s stock options and SARs.

•Expected Dividend — We have not issued any dividends and do not anticipate issuing dividends on LanzaTech’s common stock. As a result, we have estimated the dividend yield to be zero.

•Expected Volatility — Due to our limited operating history and a lack of company-specific historical and implied volatility data, we have based our estimate of expected volatility on the historical volatility of a group of similar companies that are publicly traded. The historical volatility data was computed using the daily closing prices for the various companies' shares during the equivalent period of the estimated expected term of the stock-based awards.

We estimate the fair value of market-based RSUs using the Monte Carlo simulation model that uses assumptions including expected volatility, and the derived service period. Please refer to the expected volatility discussion above.

We estimate the fair value of the RSAs and RSUs with only service conditions using the fair value of common stock on the date of measurement.

Filing Status

Section 102(b)(1) of the JOBS Act exempts “emerging growth companies” or “EGCs”(as defined in Section 2(a) of the Securities Act) from being required to comply with new or revised financial accounting standards until private companies are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can choose not to take advantage of the extended transition period and comply with the requirements that apply to non-emerging growth companies, but any such election to not take advantage of the extended transition period is irrevocable. AMCI was an emerging growth company and elected to take advantage of the benefits of the extended transition period for new or revised financial accounting standards. Following the consummation of the Business Combination, LanzaTech continued to take advantage of the benefits of the extended transition period. This may make it difficult or impossible to compare LanzaTech’s financial results with the financial results of another public company that is either not an emerging growth company or is an emerging growth company that has chosen not to take advantage of the extended transition period exemptions because of the potential differences in accounting standards used.

Additionally, following the consummation of the Business Combination LanzaTech was a “smaller reporting company” or “SRC” as defined in Item 10(f)(1) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements.

There are several requirements to continue to qualify as an EGC and/or SRC, which much be assessed at various points throughout the year. The market value of LanzaTech’s common stock that was held by non-affiliates (i.e. public float) exceeded $700 million as of the last business day of the Company’s 2023 second fiscal quarter which will result in the following changes to LanzaTech’s filing status:

•LanzaTech will become a large accelerated filer as of 12/31/2023.

•LanzaTech will lose EGC status as of 12/31/2023.

•LanzaTech no longer qualifies as an SRC as of the last business day of the Company’s second fiscal quarter. LanzaTech may continue to use the scaled disclosures permitted for SRCs through the 2023 annual report on Form 10-K, and must begin providing non-scaled larger company disclosures in its quarterly report on Form 10-Q for the first quarter of 2024. To the extent LanzaTech takes advantage of such reduced disclosure obligations prior to the first quarter of 2024, it may also make comparison of its financial statements with other public companies difficult or impossible.

Recently Issued and Adopted Accounting Standards

See Note 2 to our condensed consolidated financial statements for a description of recent accounting pronouncements, including the actual and expected dates of adoption and estimate effects on our consolidated results of operations and financial condition, which is incorporated herein by reference.

Non-GAAP Financial Measures

To supplement our financial statements presented in accordance with US GAAP and to provide investors with additional information regarding our financial results, we have presented adjusted EBITDA, a non-GAAP financial measure. Adjusted EBITDA is not based on any standardized methodology prescribed by US GAAP and is not necessarily comparable to similarly titled measures presented by other companies.

We define adjusted EBITDA as our net loss, excluding the impact of depreciation, interest income, net, stock-based compensation, change in fair value of warrant liabilities, change in fair value of SAFE liabilities, change in fair value of the FPA Put Option liability and Fixed Maturity Consideration, transaction costs on issuance of Forward Purchase Agreement, (loss) gain from equity method investees and other one-time costs related to the Business Combination and initial securities registration. We monitor and have presented in this Quarterly Report adjusted EBITDA because it is a key measure used by our management and the Board to understand and evaluate our operating performance, to establish budgets, and to develop operational goals for managing our business. We believe adjusted EBITDA helps identify underlying trends in our business that could otherwise be masked by the effect of certain expenses that we include in net loss. Accordingly, we believe adjusted EBITDA provides useful information to investors, analysts, and others in understanding and evaluating our operating results and enhancing the overall understanding of our past performance and future prospects.

Adjusted EBITDA is not prepared in accordance with US GAAP and should not be considered in isolation of, or as an alternative to, measures prepared in accordance with US GAAP. There are a number of limitations related to the use of adjusted EBITDA rather than net loss, which is the most directly comparable financial measure calculated and presented in accordance with US GAAP. For example, adjusted EBITDA: (i) excludes stock-based compensation expense because it is a significant non-cash expense that is not directly related to our operating performance; (ii) excludes depreciation expense and, although this is a non-cash expense, the assets being depreciated and amortized may have to be replaced in the future; (iii) excludes gain or losses on equity method investee; and (iv) excludes certain income or expense items that do not provide a comparable measure of our business performance. In addition, the expenses and other items that we exclude in our calculations of adjusted EBITDA may differ from the expenses and other items, if any, that other companies may exclude from adjusted EBITDA when they report their operating results. In addition, other companies may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison.

The following table reconciles adjusted EBITDA to net loss, the most directly comparable financial measure calculated and presented in accordance with US GAAP.

(1)Stock-based compensation expense represents expense related to equity compensation plans

(2)Represents costs incurred related to the Business Combination that do not meet the direct and incremental criteria per SEC Staff Accounting Bulletin Topic 5.A to be charged against the gross proceeds of the transaction, but are not expected to recur in the future, as well as costs incurred subsequent to deal close related to our initial securities registration.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to a variety of market and other risks, including the effects of changes in interest rates, inflation and foreign currency translation and transaction risks, as well as risks to the availability of funding sources, hazard events and specific asset risks.

Interest Rate Fluctuation Risk

Our primary exposure to market risk is interest rate sensitivity, which is affected by changes in the general level of U.S. interest rates, particularly because of our cash equivalents and debt security investments. Our investments are made through our commercial and investment banks and, by policy, we limit the amount of risk by investing primarily in money market funds, United States Treasury obligations, and high quality corporate bonds. Additionally, we primarily invest in short-term securities. Because of the short-term nature of the majority of our financial instruments in our investment portfolio, an immediate change in market interest rates of 100 basis points would not have a material impact on the fair market value of our cash and cash equivalents or on our financial position or results of operations.

Foreign Currency Fluctuation Risk

We are subject to foreign currency exchange risk from the translation of the financial statements of our foreign subsidiaries, whose financial condition and results of operations are reported in their local currencies and then translated into U.S. dollars at the applicable currency exchange rate for inclusion in our consolidated financial statements. Foreign currency translation adjustments were $(1.00) million and $(0.38) million for the three months ended September 30, 2023 and 2022, and were $(0.95) million and $(0.77) million for the nine months ended

September 30, 2023 and 2022, respectively. Additionally, we have contracted with and may continue to contract with foreign vendors.

Inflation Fluctuation Risk

Inflation generally affects us by increasing our cost of labor, laboratory supplies, consumables and equipment. We believe that inflation had a material effect on our business, more specifically on our costs of revenues as discussed in the sections results of operations for the three and nine months ended September 30, 2023 of our management’s discussion and analysis of our financial condition and results of operations.

ITEM 4. CONTROLS AND PROCEDURES

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. We do not expect that our disclosure controls and procedures will prevent all errors and all instances of fraud. Disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Further, the design of disclosure controls and procedures must reflect the fact that there are resource

constraints, and the benefits must be considered relative to their costs. Because of the inherent limitations in all disclosure controls and procedures, no evaluation of disclosure controls and procedures can provide absolute assurance that we have detected all our control deficiencies and instances of fraud, if any. The design of disclosure controls and procedures also is based partly on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Evaluation of Disclosure Controls and Procedures

Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rule 13a–15(e) and 15d-15(e)) as of September 30, 2023.Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were ineffective as of September 30, 2023. We are in the process of implementing measures designed to improve our disclosure controls and procedures.

Changes in Internal Control over Financial Reporting

As noted previously, subsequent to September 30, 2023 and prior to filing, we have revised the accounting treatment of the FPA to reclassify the prepaid forward contract from being presented as a net derivative asset on our condensed consolidated balance sheet to equity and non-current liability on the condensed consolidated balance sheet. We intend to restate our financial statements for the quarters ended March 31, 2023 and June 30, 2023 to be consistent with this accounting treatment. In connection with these determinations, we have concluded that the failure of our internal controls designed to ensure appropriate accounting for complex technical arrangements like the forward purchase agreement is representative of the material weakness in our internal control over financial reporting.

We are in the process of implementing measures designed to improve our internal control over financial reporting to remediate the material weakness. We believe the measures that we implement will contribute toward the remediation of the control deficiency we have identified and strengthen our internal control over financial

reporting. We are committed to continuing to improve our internal control processes and will continue to review, optimize, enhance, and test our controls and procedures. As we continue to evaluate and work to improve our internal control over financial reporting, we may take additional measures to address control deficiencies, or we may modify certain of the remediation measures. This material weakness will not be considered remediated until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively. Accordingly, the material weakness was not remediated as of September 30, 2023.

Notwithstanding the material weaknesses in internal control over financial reporting described above, our management has concluded that our consolidated financial statements included in this Quarterly Report on Form 10-Q are fairly stated in all material respects in accordance with GAAP.

PART II - OTHER INFORMATION

LEGAL MATTERS

The Company may be involved in legal proceedings and exposed to potential claims in the normal course of business. Although we cannot predict the ultimate outcome of any legal matter with certainty, we do not believe the outcome of any of our pending legal proceedings will have a material adverse impact on our consolidated financial position, results of operations or cash flows.

ITEM 1A. RISK FACTORS

Our risk factors are disclosed in Part I, Item 1A of our Annual Report on Form 10-K. Except as set forth in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2023, there have been no material changes during the nine months ended September 30, 2023 from or updates to the risk factors discussed in Part I, Item 1A. Risk Factors, of our Annual Report on Form 10-K, except for the addition of the following risk factor:

Our revenue is relatively concentrated within a small number of key customers, and the loss of one or more of such key customers may adversely affect our business, financial condition, and results of operations.

For the fiscal year ended December 31, 2022, our largest customer accounted for 22% of our revenue. For the nine months ended September 30, 2023, our largest customer accounted for 39% of our revenue. Customer mix can change rapidly, and we may see changes in customer concentrations in the future. If or when any of our significant customer relationships terminate for any reason, and we are not able to replace those customers and associated revenues, our business, financial condition, and results of operations may be adversely affected.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Except as previously reported by the Company on its Current Reports on Form 8-K, we did not sell any securities during the period covered by this Form 10-K that were not registered under the Securities Act.

ITEM 3. DEFAULTS UPON SENIOR SECURITIES

None.

ITEM 4. MINE SAFETY DISCLOSURES

None.

ITEM 5. OTHER INFORMATION

Securities Trading Plans of Directors and Executive Officers

During the three months ended September 30, 2023, none of our directors or officers adopted or terminated any contract, instruction or written plan for the purchase or sale of our securities that was intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) or any “non-Rule 10b5-1 trading arrangement” (as defined in Item 408(c) of Regulation S-K).
