Wrap up: Centrus joins S&P SmallCap; Aleut does Oak Ridge business support; Obituary

By ExchangeMonitor

Centrus Energy will join the S&P SmallCap 600 Index before markets open July 14, a move the company said reflects its growing role in rebuilding the U.S. nuclear fuel supply chain and expanding domestic uranium enrichment capacity.

“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,” President and CEO Amir Vexler said in a statement Tuesday. According to S&P Dow Jones Indices, Centrus will replace Whitestone REIT in the S&P SmallCap 600 Index, which tracks the performance of small-cap U.S. companies.

The move comes as Centrus advances an expansion of its uranium enrichment operations in Piketon, Ohio, the release said. The company launched domestic centrifuge manufacturing late last year to support the planned expansion, which is intended to increase production of low-enriched uranium, high-assay low-enriched uranium for advanced reactors, and enriched uranium for national security missions. Centrus has said the multibillion-dollar project could create thousands of jobs and rank among the nation’s largest nuclear infrastructure projects.

 

Aleut Government Services has been awarded a $6.2-million contract by the Department of Energy Office of Science for administrative and business support services at the Oak Ridge Site in Tennessee.

The award notice was posted online July 6. Aleut Government Services business address is listed as Colorado Springs, Colo., according to the notice.

Aleut Government Services is considered a small disadvantaged business by the Small Business Administration. Aleut Government Services was formed in 2021 and is a subsidiary of Aleut Federal, an Alaska Native Corporation. Aleut has much experience within the DOE nuclear complex.
