Pryme halted its testing program at Pryme One

Pryme (the “Company”) halted its testing program today as a result of a loss of containment through the connection of the discharge valve to the main body of the reactor despite the recent repairs and improvements made to the reactor discharge valve assembly. Evaluation and subsequent repair of the discharge valve assembly for its full integrity in operations require the reactor to be cooled down. The process of cooling down, evaluation of the root cause, implementing further repairs and heating up again of the installation take their time and the Company does not expect production to restart before the beginning of March 2026. Pryme will inform the market when the testing program is resumed.
