Welcome to our dedicated page for LanzaTech Global SEC filings (Ticker: LNZAW), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
LanzaTech Global, Inc. filings document the public-company record for its carbon management business and its Nasdaq-listed warrants to purchase common stock under LNZAW. The company’s reports cover financial results, business updates, liquidity-related actions, strategic initiatives, and the capital structure associated with its common stock and warrants.
Recent Form 8-K filings include results-of-operations disclosures, investor presentation materials, and a change in independent registered public accounting firm, including related audit committee and going-concern disclosures. Definitive proxy statements provide formal governance and stockholder-voting records for the company, including annual meeting matters and board-level oversight of the business.
LanzaTech Global, Inc. is asking stockholders to elect two Class III directors, ratify BDO as its new independent auditor, and approve 2025 executive pay at a fully virtual 2026 annual meeting.
The proxy details an auditor change from Deloitte, whose 2024 and 2025 reports included an explanatory paragraph about substantial doubt regarding LanzaTech’s ability to continue as a going concern. It also discloses previously identified material weaknesses in internal control over financial reporting tied to complex accounting, significant estimates and strained finance staffing, though these did not require restatements. The filing outlines non-employee director cash fees, severance paid to former executives, and a pay-versus-performance table showing compensation actually paid moving with cumulative total stockholder return and net losses, including a net loss of $49.0 million in 2025.
LanzaTech Global, Inc. changed its independent auditor, dismissing Deloitte & Touche LLP and appointing BDO USA, P.C. as auditor for the year ending December 31, 2026. Deloitte’s prior reports for 2025 and 2024 included an explanatory paragraph expressing substantial doubt about LanzaTech’s ability to continue as a going concern.
The company also reiterates that it previously identified material weaknesses in internal control over financial reporting, including issues with complex transactions, revenue recognition, and multiple components of the COSO Internal Control – Integrated Framework.

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.
