Analysis
LanzaTech Global, Inc. dismissed Deloitte & Touche LLP as its independent registered public accounting firm, effective April 10, 2026. This change is significant as Deloitte's prior audit reports for 2024 and 2025 included explanatory paragraphs regarding substantial doubt about the company's ability to continue as a going concern. Additionally, Deloitte had identified material weaknesses in internal control over financial reporting for both years. While the company stated there were no disagreements with Deloitte on accounting principles or practices, the auditor change in the context of these persistent financial and control issues raises concerns about the company's financial health and reporting environment. The company has engaged BDO USA, P.C. as its new auditor, but investors should monitor future financial disclosures for resolution of the going concern and material weakness issues.
