Pryme resumes its testing program for Pryme One

Pryme resumes its testing program for Pryme One Rotterdam, 6 March 2026

Pryme (the “Company”) has resumed its Pryme One production testing program. Start-up of production followed on to the repair and improvement made to the connection of the reactor’s discharge valve to the main body of the reactor. Approximately 60 tons of pyrolysis oil have been produced since the restart of production last Wednesday, and as operations continue.

During the testing program phase, there will be intermittent periods where production is halted as the Company is planning to test and implement various alternative improvements in the production process that may require a reset or cleaning before restarting. The Company’s emphasis will remain on executing the testing program rather than to maximizing oil production.

The Company plans to issue its next monthly production volume update on 1 April 2026.
