LanzaTech Global, Inc. furnished an investor presentation outlining its business, project pipeline, cost structure reset and liquidity plans. The company highlights six commercial plants that have produced over 60 million gallons of ethanol and a first ethanol-to-SAF plant with 10 million gallons per year capacity. 2025 revenue is shown at $57 million, with a model shifting toward higher-margin, recurring royalties and product revenue as more facilities deploy.
