LanzaTech announced the appointment of Sushmita Koyanagi as Chief Financial Officer, effective June 2, 2025, completing its previously announced search for a permanent CFO. Ms. Koyanagi succeeds Justin Pugh, who has been serving as LanzaTech’s interim CFO since January 2025 and who 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 has extensive public and private company experience in accounting, financial reporting, process improvement and managing larger teams, and most recently joined the Company as Chief Accounting Officer (“CAO”) in December of 2024.

Separately, LanzaTech announced that Amanda Fuisz will assume the role of interim General Counsel, effective June 13, 2025. Ms. Fuisz will succeed Joseph Blasko, who will step down to pursue a new professional opportunity. Ms. Fuisz, who currently serves as LanzaTech’s Deputy General Counsel, will lead LanzaTech’s legal and compliance department while serving as interim General Counsel.

“We are thrilled to have Sush take on this expanded role,” said Dr. Jennifer Holmgren, Chair and Chief Executive Officer. “Sush is a seasoned finance executive with an impressive background that makes her ideally suited to lead the next phase of our financial evolution as we advance our path to profitability. On behalf of our executive team and board of directors, I would like to thank Justin for stepping in to lead as interim CFO ensuring a seamless transition. Additionally, I am grateful to Amanda for stepping into this role as interim General Counsel. Her background and strong legal acumen make her an ideal fit for this position. I wish Joe all the best in his future endeavors,” added Holmgren.

Additionally, LanzaTech announced that Gary Rieschel, a long-serving member of LanzaTech’s board of directors, will retire at the conclusion of his current term and will not seek re-election at the Company's Annual Meeting of Stockholders on July 21, 2025.

“On behalf of the members of our board and management, I express our deep appreciation for Gary’s contributions,” stated Holmgren. “Since 2009, Gary has been an unwavering champion of LanzaTech’s mission to build a circular carbon economy. It has been a true privilege to work closely with Gary for over the past fifteen years.”

The announced leadership changes and role consolidations are anticipated to result in annual cost reductions of approximately $1 million. These cost reduction measures will enhance LanzaTech’s ability to better allocate resources toward its most promising commercial opportunities and projects, with efforts predominantly focused on leveraging the Company’s core gas fermentation technology platform to effectively be an enabler of the significant and growing momentum of sustainable aviation fuel production.
