Pryme One - change in strategy

In Q4 2024, Pryme revised its production capacity estimate for Pryme One to
16,700 tons per year, reflecting updated technical assumptions and operational
learnings. 2025 brought tremendous learnings to the team about the Pryme One
process, facility, and its potential as the Company focused on improving plant
reliability, enhancing production efficiency, and increasing the quality of its
pyrolysis oil. Pryme successfully executed its test plan, validating that the
core pyrolysis process operates effectively at scale, with high oil yields (75%)
and consistent product quality. In parallel, the Company renegotiated its main
off-take agreement, securing improved pricing  and broader product
specifications.

Despite these achievements, total production for 2025 year-to-date reached only
785 tons
