LanzaTech Global, Inc. reports another year of heavy losses and liquidity strain in its annual report for the year ended December 31, 2025. The company recorded a net loss of $49.0 million and operating cash outflows of $64.9 million, leaving cash and cash equivalents of $13.2 million and an accumulated deficit of $1,018.6 million.
Management discloses substantial doubt about LanzaTech’s ability to continue as a going concern and states that continuing operations depend on executing its business plan, raising significant additional capital and/or other strategic options. To bolster liquidity after year‑end, the company completed a $20.0 million private placement in January 2026, converted all outstanding Series A Convertible Senior Preferred Stock into 3,250,322 common shares and issued a warrant to purchase 7,800,000 common shares at a nominal exercise price.
LanzaTech positions itself as a carbon management and gas fermentation technology platform, with six commercial plants that have produced over 139 million gallons of fuel‑grade ethanol and a large intellectual property portfolio. It also holds a significant equity stake in LanzaJet, though its fully diluted ownership declined to approximately 45.6% in February 2026 following a Series A financing at LanzaJet.
LanzaTech Global reported sharply improved 2025 results but remains loss-making with tighter liquidity. Full-year revenue rose to $55.8 million from $49.6 million, helped by $16.9 million in Q4 related-party licensing revenue from LanzaJet and stronger CarbonSmart product sales.
Net loss narrowed to $49.0 million from $137.7 million, while Adjusted EBITDA loss improved to $71.3 million from $88.2 million, reflecting a 21% reduction in operating expenses to $104.5 million. Q4 was near break-even, with net loss of $0.1 million and Adjusted EBITDA of $2.4 million.
Cash and restricted cash fell to $17.1 million as of December 31, 2025 from $58.1 million a year earlier, and shareholders’ equity turned to a deficit of $3.9 million. The company highlighted strategic progress around sustainable aviation fuel through its stake in LanzaJet and a €40 million EU Innovation Fund grant.

LanzaTech Global, Inc. (LNZA) filed Amendment No. 2 to a Schedule 13D showing updated ownership by entities affiliated with Vinod Khosla. As of January 29, 2026, these reporting persons beneficially owned 11,478,998 shares of common stock, including 7,800,000 shares underlying a warrant, representing approximately 64.2% of the common stock under SEC rules.
On January 21, 2026, 20,000,000 shares of Series A Convertible Senior Preferred Stock were converted into 3,250,322 common shares, and the issuer granted a warrant to purchase 7,800,000 common shares at an exercise price of $0.0000001 per share to a preferred stockholder. The ownership percentages are calculated based on 2,320,216 common shares outstanding as of November 13, 2025, plus the converted shares, the warrant shares and 4,510,968 common shares issued that day to unaffiliated investors.
LanzaTech Global insider Vinod Khosla reported a major conversion of preferred stock into common shares and the issuance of a large warrant position. On January 21, 2026, 20,000,000 shares of Series A Convertible Senior Preferred Stock, originally purchased for $40,000,000, were automatically converted into 3,250,322 shares of common stock under the company’s Second Amended & Restated Certificate of Designation, reflecting a prior 1-for-100 reverse stock split.
Following this conversion, Khosla directly held 3,678,998 shares of LanzaTech common stock. In addition, an entity owned or controlled by him received a warrant to purchase 7,800,000 shares of common stock at an exercise price of $0.0000001 per share, exercisable until December 31, 2026 and subject to automatic cashless exercise at expiration. The warrant and certain other securities are held by that entity, with Khosla disclaiming beneficial ownership beyond his economic interest.
LanzaTech Global, Inc. disclosed that its Chief Financial Officer, Sushmita Koyanagi, filed an initial insider ownership report. In this filing, she states that she does not own any non-derivative or derivative securities of LanzaTech Global and that no securities are beneficially owned. The report confirms her role as Chief Financial Officer and is filed as an individual reporting person.
LanzaTech Global, Inc. entered into private subscription agreements with institutional investors, issuing 4,000,000 shares of common stock at $5.00 per share for gross cash proceeds of $20,000,000 and granting 510,968 bonus shares, together called the PIPE Shares. These transactions were completed as unregistered offerings under Securities Act exemptions.
The company also filed a Second Amended and Restated Certificate of Designation that, upon completion of this financing, triggered the mandatory conversion of all outstanding Series A Convertible Senior Preferred Stock into 3,250,322 shares of common stock, removing prior mandatory redemption provisions. In addition, a previously agreed warrant for 7,800,000 shares at a nominal exercise price was issued to the preferred stockholder, with its terms amended so it may be exercised any time until December 31, 2026 and will be automatically exercised on a cashless basis immediately before that time.
The largest PIPE investor gains the right to appoint a non-voting board observer while it holds at least half of its subscribed shares, and the preferred stockholder agreed to extend the deadline for registering certain warrant shares, with the company now committing to file that registration statement within 60 business days after the warrant shares are issued.

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.
