Item 8.01    Other Events

On December 22, 2025, LanzaTech Global, Inc. (“LanzaTech” or the “Company”) issued a press release announcing an increase in its ownership position in LanzaJet, Inc. (“LanzaJet”), a leading sustainable aviation fuel technology provider and fuels producer. This increase in equity is in accordance with the Second Amended & Restated LanzaJet Investment Agreement, which allowed LanzaJet to further sublicense the Alcohol-to-Jet (“ATJ”) technology originally developed by LanzaTech in collaboration with the Pacific Northwest National Lab and the U.S. Department of Energy, which enables the conversion of ethanol to sustainable aviation fuel, or “SAF”, in exchange for additional equity issued to LanzaTech. As of December 16, 2025, LanzaTech received its final tranches of LanzaJet common stock, which increased LanzaTech’s ownership percentage and non-controlling interest in LanzaJet to 53% from approximately 36%.

The sustainable aviation fuel industry remains capital-intensive and subject to evolving regulatory and market dynamics. LanzaJet, like many in the sector, is managing operational and financial pressures as it scales. LanzaTech’s increased equity interest does not imply a change in governance or control.

A copy of the Company’s December 22, 2025, press release is attached to this current report on Form 8-K as Exhibit 99.1.
