Board Appoints David Buzby as Interim Chief Executive Officer

Stem, Inc. (NYSE:STEM), a global leader in artificial intelligence (AI)-driven clean energy software and services, today announced that John Carrington has stepped down as Chief Executive Officer (CEO) and as a member of the Board of Directors, effective immediately. To ensure a smooth transition, Mr. Carrington will serve in an advisory capacity through December 31, 2024. Stem's Board, with assistance of an executive search firm, is conducting a search, which will include internal and external candidates, to identify a permanent CEO to lead Stem's evolution as a leading energy software, technology, and services company.

David Buzby, Executive Chair of the Company's Board of Directors, has been appointed interim CEO, effective immediately. Mr. Buzby will continue to serve in his current role as Executive Chair of the Board of Directors. The Company is concluding its previously announced strategy review and expects to publicly announce the outcome of its review in the coming weeks. The identification of a new permanent CEO is critical to the Company's successful execution of its new strategy.

Laura D'Andrea Tyson, Stem's Lead Independent Director, said, "On behalf of the Board, I would like to thank John for his many significant contributions to Stem. During his tenure, John led Stem in the expansion of its technology leadership, as it made vast strides in innovation, raised growth capital, and delivered exceptional service to customers. We wish John the best in his future endeavors."

Mr. Carrington said, "It has been a privilege to serve as the CEO of Stem for more than a decade, and I am extremely proud of all we accomplished, included building an exceptional leadership team, making Stem a leader in the energy transition, and executing on a successful initial public offering in 2021. I have complete confidence in our outstanding global team, including in David as interim CEO, and look forward to the Company's evolution in its next phase of software and services growth."

Ms. Tyson continued, "As a founding investor and since joining Stem's Board, David has provided outstanding guidance and oversight and has been a driving force in building Stem into a global leader in clean energy solutions. David is an industry veteran with a proven track record of investing in, and building, companies at the forefront of the energy transition. As we conduct our search for a permanent CEO, I am confident that David is the right leader to promote Stem's focus on growing software and services revenue and on maximizing stockholder value. I also look forward to the instrumental support that Doran Hole, our newly appointed Chief Financial Officer and Executive Vice President, as well as the rest of our very talented senior leadership team, will provide David during this critical time in Stem's evolution."
