LanzaTech Global, Inc. (LNZA) reported Q3 2025 revenue of $9.3 million, slightly below the prior year, while nine‑month revenue declined to $27.8 million from $37.6 million. The company sharply reduced costs, cutting research and development and selling, general and administrative expenses, which narrowed its Q3 operating loss to $15.7 million from $33.0 million. Favorable fair value movements on financing instruments drove net income of $2.9 million, compared with a large loss a year earlier, although the company still posted a $48.9 million loss for the first nine months.
Cash and cash equivalents fell to $19.6 million at September 30, 2025 from $43.5 million at year‑end, with $58.7 million used in operating activities over nine months. Management states there is substantial doubt about LanzaTech’s ability to continue as a going concern without raising significant additional capital or executing other strategic options. During the period, the company issued 20.0 million shares of Series A convertible preferred stock and converted a $40.2 million convertible note into 340,543 common shares, and it completed a 1‑for‑100 reverse stock split to consolidate its share count and maintain its listing.
LanzaTech Global, Inc. (LNZA) filed a Form 8-K to report that it issued a press release announcing its financial results for the quarter ended September 30, 2025. The press release is furnished as Exhibit 99.1 and provides the company’s third-quarter 2025 earnings information. The company notes that this information is being furnished, not filed, which limits how it is treated under securities laws and how it is incorporated into other regulatory documents.
LanzaTech Global, Inc. filed a Form 12b-25 to notify a late filing of its Form 10-Q for the fiscal quarter ended September 30, 2025. The company cites reduced internal resources following a cost-cutting reduction in force as the reason it cannot complete the report on time without unreasonable effort or expense, and it plans to file within the extension period allowed under Rule 12b-25.
For Q3 2025, LanzaTech currently expects net income to increase in the high double digit percentage range versus Q3 2024, mainly from a favorable change in the fair value of derivative instruments rather than better operating performance, cash flows, or underlying profitability. It also expects cost of revenues (excluding depreciation) to decline in the low double digit percentage range and total operating expenses to decline in the mid-double digit percentage range, driven by project completions and headcount reductions. These figures are preliminary and may change when the unaudited financial statements are finalized.
LanzaTech Global (LNZA) entered into amended agreements with LanzaJet and partners to update ownership, financing, and licensing terms tied to LanzaJet’s sustainable aviation fuel platform.
The new Second Amended and Restated Investment Agreement removes the prior project‑specific investment condition and provides that LanzaJet will issue to LanzaTech a second tranche of 15,000,000 LanzaJet shares promptly after execution and a third tranche of 15,000,000 shares no later than December 31, 2025, or promptly after a specified development milestone if not achieved by those dates. If LanzaJet undertakes a sale or IPO before those issuances and LanzaTech would hold under 50% immediately prior to completion, LanzaJet will issue additional shares so LanzaTech holds at least 50%.
The amendment also permits certain lenders to convert loans to LanzaJet shares at a fair market value price set by disinterested directors. The license amendment lifts certain sublicensing restrictions, removes LanzaTech’s right to terminate the license if commercial milestones are not met by December 31, 2025, and commits LanzaTech to use commercially reasonable efforts to assign the Battelle License to LanzaJet.
LanzaTech Global, Inc. entered into several agreements related to its existing Series A Convertible Senior Preferred Stock financing. The company previously sold 20,000,000 shares of this preferred stock to an investor-controlled entity for $40,000,000 on May 7, 2025. On September 22, 2025, the parties signed a second amendment to the purchase agreement that extends the deadline for the company to complete a "Subsequent Financing" of common stock with proceeds to the company of not less than $35,000,000 and not more than $60,000,000 to no later than October 15, 2025, and allows multiple closings.
The company also filed a Certificate of Amendment to the Amended and Restated Certificate of Designation for the Series A preferred stock to reflect these changes. In addition, LanzaTech and the investor entered into a Waiver Agreement adjusting the timing of the company’s obligation to file a registration statement for certain common shares. The investor waived earlier deadlines, and the company now agrees to file the registration statement no later than 10 business days after issuing warrant shares.
