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. furnished an update on its financial performance by issuing a press release with results for the quarter and six months ended June 30, 2025. The company filed a current report to make this press release publicly available and attached it as Exhibit 99.1.
The disclosure is designated as “furnished” rather than “filed,” meaning it is not subject to certain liability provisions of the Securities Exchange Act and is not automatically incorporated into other Securities Act or Exchange Act filings unless specifically referenced.
LanzaTech Global, Inc. filed a Form 12b-25 notifying the SEC of a late NT 10-Q for the quarter ended June 30, 2025 (Q2 2025). The company expects revenue to decline in Q2 2025 versus Q2 2024 by a mid-double digit percentage and cost of revenues (exclusive of depreciation) to increase in Q2 2025 versus Q2 2024 by a low double digit percentage. These figures are described as preliminary and subject to change when the unaudited consolidated financial statements are finalized. The filing also contains standard forward-looking statements language and notes that actual results may differ materially from the preliminary expectations.
LanzaTech Global, Inc. reported two key corporate actions. First, the company announced at an August 13, 2025 town hall that President Aura Cuellar will step down from her role, with the effective date still to be determined. The company stated that her departure is not due to any disagreement over operations, policies, or practices and thanked her for her service.
Separately, the company disclosed that it will implement a 1-for-100 reverse stock split of its common stock, effective August 18, 2025 at 5:00 p.m. Eastern Time. Immediately before that time, it will decrease the par value of its common stock from $0.0001 to $0.0000001 per share and increase authorized common shares from 600,000,000 to 2,580,000,000, which will be proportionately decreased to 25,800,000 at the reverse split effective time. These actions were approved by stockholders at the 2025 annual meeting.
LanzaTech Global, Inc. (Nasdaq: LNZA/LNZAW) has filed a Form 8-K announcing the resignation of its Chief Accounting Officer. Michael Heraty notified the company on June 16, 2025 that he will step down effective June 26, 2025. The filing explicitly states that his departure is not related to any disagreement over accounting, financial reporting, or company practices.
Upon Heraty’s exit, Chief Financial Officer Sushmita Koyanagi will assume the additional title of Principal Accounting Officer. No separate compensation package or new employment agreement will be put in place for this expanded role. The company incorporates Ms. Koyanagi’s previously disclosed biography from an 8-K dated May 29, 2025.
The filing contains no other financial data, strategic updates, or operational changes. Consequently, the event is limited to a governance transition rather than a change affecting near-term earnings, liquidity, or strategic direction.

- Governance items include election of two Class II directors, ratification of Deloitte & Touche LLP, an advisory vote on executive compensation, authority for shareholders to act by written consent, and a proposal to reduce the par value of common stock from $0.0001 to $0.0000001.
