Power of Attorney Filing for David Park's Section 16 Reporting at Oklo Inc.

This SEC Form 3 filing documents a Power of Attorney executed by David Park, a director of Oklo Inc., authorizing designated company officials to file Section 16 reports on his behalf. The filing, dated April 2026, grants authority to four individuals including CEO Jacob DeWitte, COO Caroline DeWitte, CFO Richard Craig Bealmear, and General Counsel Vivek Narayanadas to prepare and submit Forms 3, 4, and 5 as well as Schedules 13D and 13G related to Park's holdings and transactions in Oklo securities. The power of attorney remains in effect until Park is no longer required to file such reports or until revoked in writing. This is a standard administrative filing that facilitates compliance with SEC reporting requirements for company insiders, allowing designated attorneys-in-fact to handle the technical filing requirements while the director retains ultimate responsibility for compliance.
