Borregaard ASA: Temporary disruption in production of speciality cellulose

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.
