Nexgen Energy Ltd. shares rise 2.24% premarket after ATHA Energy Corp. announced a revised financing agreement with Stifel Canada.

Nexgen Energy Ltd. rose 2.24% in premarket trading. The company's stock price increase may be attributed to the recent news that ATHA Energy Corp. has entered into a new engagement agreement with Stifel Canada to act as lead underwriter and sole bookrunner in connection with an underwritten private placement offering of special warrants. This revised agreement replaces the 'best efforts' private placement agreement previously announced on August 11, 2025.
