Oklo Inc. (NYSE: OKLO) announced changes to its board of directors and management team, according to a company press release. The nuclear technology company appointed four new directors effective April 10, 2026: Dr. Mark Peters, David Christian, Derek Kan, and David Park.

Dr. Peters serves as president and CEO of MITRE and previously led Idaho National Laboratory. Christian is former executive vice president and chief innovation officer for Dominion Energy. Kan currently serves as vice president of business operations at Shopify and vice chairman of the United States Postal Service Board of Governors. Park is CEO of Standard Lithium (NYSE: SLI) and has 28 years of energy and industrial sector experience.

The company also appointed Michael Thompson as lead independent director. Thompson joined Oklo's board last year and will provide independent oversight to the management team.

Oklo announced that Chief Technology Officer Pat Schweiger will transition to a senior technical advisory role. The company and Schweiger mutually agreed to this change as part of efforts to restructure management around four business units focusing on powerhouse deployment, fuel fabrication, fuel recycling, and radioisotope production.

"His decades of experience designing and building fast reactors enabled us to move rapidly as we broke ground and made significant strides designing our first-of-a-kind Aurora powerhouse at INL," said CEO Jacob DeWitte regarding Schweiger's contributions.

The changes are designed to support Oklo's expansion across its integrated power-fuel-isotopes business. The company develops fast fission power plants and was the first to receive a site use permit from the U.S. Department of Energy for a commercial advanced fission plant.
