Debt Disclosure [Abstract] |
Brookfield Instruments | Brookfield Instruments On October 2, 2022, the Company entered into the Brookfield SAFE under which the Company agreed to issue to Brookfield the right to certain shares of its capital stock, in exchange for the payment of $50,000 (the “Initial Purchase Amount”). The Brookfield SAFE was legal form debt, however it could be converted into a maximum number of shares of 5,000,000. Management elected to apply the Fair Value Option ("FVO") under ASC 825, Financial Instruments. As the Brookfield SAFE was accounted for under the FVO, the Brookfield SAFE was classified as a mark-to-market liability. On the fifth anniversary of the Brookfield SAFE, LanzaTech was required to repay in cash the Initial Purchase Amount less any Non-Repayable Amount (the “Remaining Amount”), as well as interest on such Remaining Amount of 8.0%, compounded annually. For each $50,000 of aggregate equity funding required for qualifying projects presented to Brookfield in accordance with the Brookfield Framework Agreement (discussed below), the Remaining Amount would be reduced by $5,000 (such cumulative reductions the “Non-Repayable Amount”) and converted into LanzaTech Shares at $10.00 per share. Interest on the corresponding amount would be forgiven. Each project presented must have met certain criteria in order to be considered a qualifying project. On February 14, 2025, the Company and Brookfield terminated the Brookfield SAFE and all rights and obligations, and concurrently entered into the Brookfield Loan (as defined below). As of that date, the Brookfield SAFE had not converted as a qualifying financing had not occurred and no qualified project investments had been presented to Brookfield. The Framework Agreement, as described below, remains in full effect. Management considered the terms of the Brookfield SAFE and the Brookfield Loan to be substantially different per ASC 470-50 – Debt: Modifications and Extinguishments. As such, the exchange of instruments was accounted for as the extinguishment of the Brookfield SAFE and the recognition of a new debt instrument, “the Brookfield Loan”. As of February 14, 2025, the Company recognized a loss of $6,216 on extinguishment of the Brookfield SAFE in other expenses/income on the consolidated statements of operations and comprehensive loss. Brookfield Framework Agreement On October 2, 2022, LanzaTech entered into a framework agreement with Brookfield (as amended by Amendment No. 1 to the Brookfield Framework Agreement, dated July 10, 2025, the “Brookfield Framework Agreement”) for an initial term ending December 3, 2028. Under such agreement, LanzaTech agreed to exclusively offer Brookfield the opportunity to acquire or invest in certain projects to construct commercial production facilities employing carbon capture and transformation technology in the U.S., the European Union, the United Kingdom, Canada or Mexico for which LanzaTech is solely or jointly responsible for obtaining or providing equity financing, subject to certain exceptions. LanzaTech agreed to present Brookfield with projects that over the term of the agreement require equity funding of at least $500,000 in the aggregate. With respect to projects acquired by Brookfield, LanzaTech is entitled to a percentage of free cash flow generated by such projects determined in accordance with a hurdle-based return waterfall. Brookfield has no obligation under the Brookfield Framework Agreement to invest in any of the projects. There had been no investments in projects as of December 31, 2025 or 2024. Brookfield Loan On February 14, 2025, LanzaTech and Brookfield entered into a Loan Agreement (the “Original Brookfield Loan Agreement”), and concurrently terminated the Brookfield SAFE. Under the Original Brookfield Loan Agreement and effective as of the termination of the Brookfield SAFE, Brookfield was deemed to have loaned to LanzaTech, and LanzaTech was deemed to have borrowed from Brookfield $60,031 (the “Brookfield Loan”), representing the $50,000 initial amount under the Brookfield SAFE plus accrued interest at a rate of 8.00% per annum, compounded annually from October 2, 2022 to and including February 14, 2025. The initial principal payment of $12,500 to Brookfield was due on or prior to February 21, 2025 and has been paid. For each $50,000 of aggregate equity funding required for qualifying projects presented to Brookfield in accordance with the Framework Agreement, $5,000 of the remaining outstanding principal amount (the “Remaining Amount”) under the Original Brookfield Loan Agreement would be deemed to be repaid. On July 10, 2025, the Company and Brookfield entered into Amendment No. 1 to the Original Brookfield Loan Agreement (the “Amended Brookfield Loan Agreement”). Under the Amended Brookfield Loan Agreement, (i) the maturity date of the Brookfield Loan is extended from October 3, 2027 to December 3, 2029 (the period from October 4, 2027 to December 3, 2029, the “extension period”), (ii) interest will accrue on a daily basis on the Remaining Amount at (a) 8.00% per annum, compounded annually, through and including October 3, 2027, (b) 8.00% per annum, payable quarterly in cash, from October 4, 2027 through and including December 3, 2028 and (c) 12.00% per annum, payable quarterly in cash, from December 4, 2028 through and including December 3, 2029 and (iii) during the extension period, the deemed repayment provisions set forth in the Original Brookfield Loan Agreement associated with equity funding required for qualifying projects will not apply to eligible projects under the Amended Brookfield Framework Agreement with respect to which Brookfield has (or is deemed to have) delivered a rejection notice. The Remaining Amount, plus accrued interest will be repayable in cash upon the earlier of (i) December 3, 2029, (ii) the occurrence of certain change of control events or (iii) a breach of the Amended Brookfield Loan Agreement. The Brookfield Loan is legal form debt and management has elected to apply the FVO with the Brookfield Loan classified as a mark-to-market liability. As of December 31, 2025, no qualifying financing had yet occurred and no qualified project investments had been presented to Brookfield, therefore no portion of the Brookfield Loan was deemed repaid. As of December 31, 2025, the fair value of the Brookfield Loan was $10,900 and was recorded within the Brookfield Loan liability on the consolidated balance sheets. Refer to Note 10 — Fair Value Measurement for further details on the Brookfield SAFE and the Brookfield Loan’s fair value measurement and liabilities recorded as of December 31, 2025 and associated changes to their respective fair value for the year ended December 31, 2025.
