Inclusion reflects Centrus' growing role in advancing U.S. energy security by strengthening America's nuclear fuel supply chain

BETHESDA, Md., July 7, 2026 /PRNewswire/ -- Centrus Energy Corp. (NYSE:LEU), a trusted American supplier of nuclear fuel and services, today announced that the company is set to join the S&P SmallCap 600 Index, effective prior to the opening of trading on Tuesday, July 14, 2026.

The company's inclusion in the S&P SmallCap 600 marks an important milestone for Centrus as it works to restore America's domestic uranium enrichment capabilities, strengthen the U.S. nuclear fuel supply chain, and support the nation's long-term energy security and energy independence.

"Centrus is proud to play a leading role in rebuilding our nation's domestic nuclear fuel infrastructure at a time when reliable, affordable and secure sources of American energy are more important than ever," said Amir Vexler, President and CEO of Centrus. "Our invitation into the S&P SmallCap 600 reflects the progress our team has made and the expanding role that Centrus will play in fueling the future of nuclear energy here at home and around the world."

Late last year, Centrus launched domestic centrifuge manufacturing to support a major expansion of its uranium enrichment plant in Piketon, Ohio, which is expected to create thousands of jobs across the United States. The expansion will help meet to meet the growing need for commercial Low-Enriched Uranium (LEU) for the existing fleet of nuclear reactors; commercial High-Assay, Low-Enriched Uranium (HALEU), an advanced nuclear fuel needed by many next-generation reactor designs; as well as enriched uranium needed for national security missions. The anticipated multi-billion-dollar scope would make the expansion one of the largest nuclear infrastructure construction projects underway in the United States today.

Last week, Centrus announced that it has signed a contract to finalize the terms of the competitively-awarded, $900 million task order it received earlier this year from the U.S. Department of Energy.

The S&P SmallCap 600 is designed to measure the small-cap segment of the U.S. equity market. Inclusion in the index follows S&P Dow Jones Indices' announcement that Centrus will replace Whitestone REIT in the index.
