On December 9, 2024, it was announced that Boliden had entered into an agreement with Lundin Mining to acquire the Somincor copper and zinc mine in Portugal and the Zinkgruvan zinc mine in Sweden. The cash consideration paid to the seller on April 16, 2025, amounted to USD 1.40 billion and consisted of a purchase price of USD 1.30 billion on a debt- and cash free enterprise value basis as of August 31, 2024 (locked-box date), adjusted for interest from the locked-box date and other customary adjustments. Future contingent payments of up to USD 150 million are tied to commodity prices and satisfaction of certain conditions as outlined in the press release dated December 9, 2024. The acquisition will almost double Boliden's zinc concentrate production and significantly strengthen its copper concentrate production.

"The acquisition consolidates Boliden's position as the leading base metals company in Europe. These well-invested operations will contribute to value creation within Boliden from the outset. Just like our existing mines, we will also work long-term to create further development opportunities, " says Mikael Staffas, President and CEO of Boliden.

The acquisition was financed through a bridge loan and a directed share issue that raised approximately SEK 3.75 billion for Boliden. The bridge loan will be refinanced through a temporary deviation from Boliden's dividend policy as proposed to the Annual General Meeting and through medium and long-term debt financing in line with what has previously been communicated.
