Pryme production status update							

Rotterdam, 28 November 2025

During November 2025, Pryme (the "Company") did not produce any pyrolysis oil on
account of the production stop as communicated in the previous Pryme production
status updates on 3 and 5 November 2025. The Company has evaluated the root
cause of the failure of the reactor sleeve's securing mechanism and it has
decided to restore and secure the sleeve with an improved technical design. The
implementation involves the delivery of customized components with lead times
that will go beyond November 2025. The Company estimates to restart production
not before the second half of December. Pryme will inform the market when
production has been resumed for the continuation of its testing, debottlenecking
and optimization program. The production forecast for Q4 2025 of 600 mT of
pyrolysis oil is no longer valid given the limited remaining time until the end
of the year.
