In a shareholder update on 14 April, Rolls-Royce SMR said Rolls-Royce plc and BNF Resources had acquired Constellation’s equity interest of less than 5% in the Rolls-Royce SMR business in December 2025. The transaction was not announced at the time.
“Constellation is now focusing its strategy and resources on the increasing demand for nuclear energy in the United States and maximising output from its existing fleet,” the update said. The transaction was supported by all shareholders – Rolls-Royce plc, CEZ Group, BNF Resources Ltd, and Qatar Investment Authority (QIA).
By exiting the Rolls-Royce SMR venture, Constellation Energy is effectively doubling down on its domestic operations, particularly as the US sees a massive surge in demand driven by AI data centres and federal tax incentives.
For Rolls-Royce, regaining that equity alongside BNF Resources suggests strong internal confidence in their modular reactor design as they move toward final regulatory approvals in the UK.
