Boliden will announce its Interim Report for the first quarter 2026 on Tuesda

As previously communicated, the abnormal seismic activity at the Garpenberg m

The abnormally high seismic activity in Garpenberg has decreased and mining production at low levels will commence in the second quarter. The first quarter throughput was just under 0.8 Mton instead of the expected slightly over 0.9 Mton at already communicated grades. All inspections are not yet complete but production in the most affected part of the mine is not expected to resume in 2026. Until further notice, Garpenberg's production is therefore estimated to be around 30 percent of the guided capacity of 3.7 Mton per year. For the first quarter of 2026, EBITDA will be negatively affected by approximately SEK -400 million at today's prices and terms.
