Cameco Signs Long-Term UF₆ Supply Agreement with Slovenské elektrárne

September 12, 2025

Cameco (TSX: CCO; NYSE: CCJ) has finalized a new long-term agreement to supply natural uranium hexafluoride (UF₆) to Slovenské elektrárne (SE) for use in its nuclear power plants in Slovakia. This agreement, which consists of uranium and conversion services, is expected to provide a diversified and secure source of natural UF₆ for SE through 2036. The material will support operations at SE's Bohunice and Mochovce nuclear facilities, starting in 2028.

Members of Cameco's marketing team joined SE representatives for a small gathering in London earlier this month to celebrate the agreement.

"Cameco is proud to play an essential role helping Slovakia meet its nuclear fuel needs. With this long-term agreement, we are adding a new market to our global commercial portfolio and supporting Slovakia with a stable, reliable supply of uranium fuel that is expected to enhance energy security in the region," said Cameco CEO Tim Gitzel.

"Conversion is one of the most critical parts of the nuclear fuel cycle - the process by which natural uranium is converted into a form suitable for enrichment and reprocessing. Slovenské elektrárne has succeeded in securing a long-term and reliable supply of a significant share of this key raw material until 2036, which is a significant step for Slovakia's energy security. The contract is strategic for Slovenské elektrárne - allowing us to diversify our suppliers, reduce our dependence on one source, and at the same time guarantee the smooth operation of our nuclear power plants," said Branislav Strýček, Chairman and CEO of Slovenské elektrárne.

Details of the contract are commercially confidential.
