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.
