Sam Altman to serve as chairman of newly appointed board of directors for Oklo

AltC to deliver $306 million of gross proceeds to accelerate Oklo's business plan

Business combination expected to close May 9, 2024

NEW YORK, May 7, 2024 /PRNewswire/ -- AltC Acquisition Corp. ("AltC") (NYSE: ALCC), a special purpose acquisition company, is pleased to announce that in a special meeting held today, AltC stockholders voted to approve the business combination between AltC and Oklo Inc. ("Oklo"), a fast fission clean power technology and nuclear fuel recycling company. Almost 100% of the votes cast at the meeting, representing approximately 72.7% of AltC's outstanding shares, voted to approve the business combination (the "Transaction").

AltC stockholders also voted to elect seven directors to the post-closing board of directors, comprised of proven industry leaders with deep operational, technical, and financial expertise, as well as strong networks across important end-markets to Oklo:

• Sam Altman (chairman) – current chairman of Oklo and chief executive officer of AltC
• Michael Klein – current chairman of AltC
• Jacob DeWitte – co-founder and chief executive officer of Oklo
• Caroline Cochran – co-founder and chief operating officer of Oklo
• Lieutenant General (Ret.) John Jansen – United States Marine Corps
• Richard Kinzley – retired chief financial officer of Black Hills Corporation (NYSE: BKH)
• Chris Wright – current chief executive officer of Liberty Energy Inc. (NYSE: LBRT)

The strong support from AltC's stockholders will result in Oklo receiving over $306 million of gross proceeds (the "AltC proceeds") upon closing of the Transaction, representing almost 100% of the AltC cash in trust prior to the redemption deadline.

Upon closing of the Transaction, Oklo will have a strong balance sheet through the combination of the AltC proceeds and a recent $25 million customer prepayment. Oklo stands well positioned to execute its mission to provide clean, reliable, affordable energy on a global scale through the design and deployment of next-generation fast reactor technology. Oklo has received strong customer interest in its Aurora powerhouse offering and has been purpose-built to meet the rapidly expanding electric power needs of the artificial intelligence, data center, energy, defense, and industrial markets, among others.

The completion of the Transaction is expected to occur on May 9, 2024, subject to the satisfaction of applicable closing conditions. Upon closing of the Transaction, the combined company will be named Oklo Inc., and it is anticipated that shares of its class A common stock will begin trading on the New York Stock Exchange ("NYSE") with the ticker "OKLO" on May 10, 2024.
