Rotterdam, 30 September 2025

During September 2025, Pryme (the "Company") did not produce any pyrolysis oil.
The reason for the stop in the production is the repairs of the reactor's
sealing system as announced on 9 September 2025.

In total, the Company produced 468 tons of pyrolysis oil in Q3 or around 50% of
the low range of the Q3 production forecast, again caused by the required
repairs during the quarter.

The Company estimates to restart production around mid-October dependent on the
successful execution of the ongoing repairs. Pryme will inform the market when
production has been resumed.

The production forecast for Q4 2025 will be provided in the outlook section of
the Q3 2025 report to be published on 6 November 2025.
