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).

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.
