Borregaard ASA: Temporary disruption in production of speciality cellulose

15 Sep 2025 17:03 CEST

Borregaard has experienced an unforeseen outage at a facility at the Sarpsborg
site, which supplies a key chemical used in the production of speciality
cellulose. During the period of the outage, cellulose production was restricted
to grades outside standard specifications, resulting in delays of shipments of
certain speciality cellulose grades.

Production of other products at the biorefinery - including lignin-based
biopolymers, bio-vanillin, bioethanol, and cellulose fibrils - remained
unaffected.

Borregaard has worked with internal and external experts to resolve the issue
and minimise the impact on customers.

Deliveries of speciality cellulose in the 3(rd) quarter are now expected to
total approximately 30,000 tonnes, compared with the previously forecasted range
of 35,000 to 38,000 tonnes as communicated in the 2(nd) quarter report. The
estimated negative impact on the Group's EBITDA for the 3(rd) quarter is in the
range of NOK 40-50 million.
