AltC Acquisition Corp. Announces Stockholder Approval of Extension Amendment Proposal at Special Meeting and Extends the Redemption Reversal Deadline

In Excess of $300 Million Will Remain in AltC's Trust Account after Stockholder Redemptions

Deadline for Redemption Reversals is Extended to 5:00 p.m. Eastern Time on October 11, 2023

NEW YORK, Oct. 5, 2023 /PRNewswire/ -- AltC Acquisition Corp. (NYSE: ALCC) ("AltC"), a publicly-traded special purpose acquisition company, today announced that in a special meeting of AltC's stockholders held today at 11:00 a.m. Eastern Time, its stockholders voted to approve a proposal to extend the date by which AltC may consummate a business combination from October 12, 2023, to July 12, 2024.

AltC will have in excess of $300 million remaining in its trust account (the "Trust Account") after taking into account redemptions by AltC stockholders. In order to allow AltC stockholders an opportunity to reverse redemption elections (an "Election Reversal"), AltC has determined to extend the deadline to do so until 5:00 p.m. Eastern Time, on October 11, 2023. To effectuate an Election Reversal, stockholders must submit a written request to AltC's transfer agent, Continental Stock & Transfer Company. If shares are held in street name, stockholders will need to instruct their bank or broker to request the Election Reversal from the transfer agent.

As announced on July 11, 2023, AltC has entered into a definitive agreement to enter into a business combination (the "proposed transaction") with Oklo Inc. ("Oklo"), an advanced fission technology and nuclear fuel recycling company. Upon closing, this transaction will result in Oklo being the first publicly traded advanced fission company focused on selling clean, reliable energy directly to customers and nuclear fuel recycling services to the U.S. market.

Since announcing the proposed transaction with AltC, Oklo has announced its tentative selection as the contractor awardee to provide power and heat to the Eielson Air Force Base in Alaska and the signing of a new Memorandum of Understanding with Centrus Energy Corp. ("Centrus"). Under this new Memorandum of Understanding, Oklo and Centrus intend to enter into definitive agreements on a broad scope of collaboration activities supporting the development and operation of Oklo's Aurora powerhouses, including collaboration related to supply of HALEU and Centrus' purchase of power from Oklo to power its HALEU Production Facility. Additionally, Oklo appointed Craig Bealmear, an experienced public energy company executive, as CFO.

The proposed transaction is currently expected to close in late 2023 or early 2024 and is subject to approval by AltC shareholders, the Registration Statement being declared effective by the U.S. Securities and Exchange Commission ("SEC"), and other customary closing conditions. Upon completion of the transaction, the combined company will operate as Oklo and is expected to be listed on the New York Stock Exchange under the ticker "OKLO."
