Executive Leadership Transitions
On May 29, 2025, LanzaTech Global, Inc. (the “Company”) announced certain transitions in its executive leadership team in connection with its recent financing and ongoing strategic measures, to streamline its operations and reduce costs, including the consolidation of certain positions by drawing upon its capable, experienced internal resources. In furtherance of these objectives, the Company determined that, effective June 2, 2025, Justin Pugh would step down from his role as the Company’s interim Chief Financial Officer and Sushmita Koyanagi, the Company’s current Chief Accounting Officer, would take on the position of Chief Financial Officer. Mr. Pugh will maintain an advisory role with the Company to assist in his transition and to provide other related support until June 30, 2025.
Ms. Koyanagi, 47, joined the Company in December 2024 as the Company’s Chief Accounting Officer. She is a seasoned finance professional with extensive experience in accounting, financial reporting, process improvement and managing large teams. Prior to her position at the Company, she served in various senior financial roles in Equity LifeStyle Properties, a leading owner and operator of manufactured home communities, RV resorts and campgrounds, from June 2021 to December 2024, JP Morgan Chase from October 2013 to June 2021 and Deloitte from July 2007 to October 2013. Ms. Koyanagi is a certified public accountant, and her educational background includes a Master’s in Accounting from Victoria University and a Bachelor of Accounting from Delhi University.
Ms. Koyanagi is party to an existing Employment Agreement with the Company that provides for a base salary of $325,000 and eligibility for a discretionary annual cash bonus determined in accordance with the Company’s bonus policy as in effect from time to time with a target of 30% of her base salary, as well as other benefit plans and programs generally made available to the Company’s executives. Under the agreement, Ms. Koyanagi is entitled to sign-on awards with a value of $150,000 in the aggregate, subject to certain vesting and repayment provisions. Further, Ms. Koyanagi is entitled to certain severance rights in the event of a termination without “cause” or for “good reason”: (i) a lump sum payment equal to six months of base salary (or nine months following a “corporate transaction”); (ii) a prorated annual bonus for the year in which the termination occurs based on actual performance; and (iii) a COBRA premium supplement of up to six months with respect to an amount equivalent to the employer-paid portion of health insurance premiums for active employees. Ms. Koyanagi is subject to certain restrictive covenants in favor of the Company.
On May 22, 2025, Joseph Blasko, General Counsel and Corporate Secretary, notified the Company of his decision to resign, effective June 13, 2025, in order to pursue another professional opportunity. Amanda Koenig Fuisz, Deputy General Counsel, will serve as interim General Counsel effective as of such date. The Board of Directors of the Company (the “Board”) and the Company wishes to thank Mr. Blasko for his dedicated service to the Company.
Director Retirement

His term ends at the Company’s 2025 Annual Meeting of Stockholders scheduled to be held on July 21, 2025. Mr. Rieschel’s decision did not result from any disagreement with the Company, its management or the Board on any matter related to the Company’s operations, policies or practices. The Board and the Company wishes to thank Mr. Rieschel for his 16 years of dedicated service on the Board.
