Rottneros

Rottneros has decided to write down the value of fixed assets in Rottneros Mill. The reason is that the mill cannot utilize its full capacity in the prevailing weak market for the mechanical pulp CTMP. The impairment charge amounts to 140 MSEK. In line with previous communication, the mill is reducing personnel to counteract the impact on earnings due to the weak demand. The Group's current cost base is expected to decrease by 35 - 40 MSEK on an annual basis, with full impact in the autumn of 2025.

The impairment charge will impact the Group's results for the second quarter, which will be published in full on 12 August 2025.
