These forward-looking statements are subject to known and unknown risks, uncertainties and assumptions about us that may cause our actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by such forward-looking statements. Such risks and uncertainties include changes in domestic and foreign business, market, financial, political and legal conditions; Oklo’s pursuit of an emerging market, with no commercial project operating;

Oklo’s potential need for financing to grow its business and/or to construct its powerhouses or other facilities; the inability of the parties to successfully or timely consummate the proposed transaction, including the risk that any required regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the new public entity following the business combination (the “Post-Closing Company”) or the expected benefits of the proposed transaction or that the approval of AltC stockholders or Oklo stockholders is not obtained; the outcome of any legal proceedings that may be instituted against Oklo or AltC following announcement of the business combination; failure to realize the anticipated benefits of the proposed transaction; the risk that shareholders of AltC could elect to have their shares redeemed by AltC, thus leaving the Post-Closing Company insufficient cash to grow its business; risks relating to the uncertainty of the projected financial information with respect to Oklo, including conversion of reservations into binding orders; risks related to the timing of expected business milestones and commercial launch; risks related to future market adoption of Oklo’s offerings; the effects of competition; changes in regulatory requirements, governmental incentives and fuel and energy prices;

the ability to recognize the anticipated benefits of the proposed business combination, which may be affected by, among other things, competition, and the ability of the Post-Closing Company and Oklo to grow and manage growth profitability; the impact and potential extended duration of the current supply/demand imbalance in the market for high-essay low-enriched uranium; whether government funding for high-assay low-enriched uranium for government or commercial uses will result in adequate supply on anticipated timelines to support Oklo’s business; the Post-Closing Company’s, Oklo’s and their commercial partners’ ability to obtain regulatory approvals necessary to deploy small modular reactors in the U.S. and abroad in a timely way, or at all; risks relating to the negative public or political perception of Oklo or the nuclear energy industry in general; the outcome of any potential litigation, government and regulatory proceedings, investigations and inquiries; the impact of the COVID-19 pandemic on Oklo’s, AltC’s, and the Post-Closing Company’s projected results of operations, financial performance or other financial metrics, or on any of the foregoing risks;

If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that neither Oklo nor AltC presently know or that Oklo and AltC currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect Oklo’s and AltC’s expectations, plans or forecasts of future events and views as of the date of this communication. Oklo and AltC anticipate that subsequent events and developments will cause Oklo’s and AltC’s assessments to change. However, while Oklo and AltC may elect to update these forward- looking statements at some point in the future, Oklo and AltC specifically disclaim any obligation to do so. These forward-looking statements should not be relied upon as representing Oklo’s and AltC’s assessments as of any date subsequent to the date of this communication. Accordingly, undue reliance should not be placed upon the forward-looking statements.
