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.

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.
