In April 2025, Boliden AB's Annual General Meeting adopted new instructions for appointing the Nomination Committee, according to which the company's Nomination Committee shall consist of members appointed by each of the three largest shareholders in the company in terms of votes, according to Euroclear Sweden AB's printout of the share register as of August 31, who have been willing to participate. Taking into account certain changes in ownership that have occurred since that date, the Nomination Committee has now been appointed and consists of the following members:
 

• Lennart Francke, Swedbank Robur Fonder, Chair of the Nomination Committee
• Magnus Tell, Alecta
• Karin Eliasson, Handelsbanken Fonder

The Chair of the Board, Karl-Henrik Sundström, has been co-opted to the Nomination Committee.

Prior to the 2026 Annual General Meeting, the Nomination Committee shall prepare proposals for the Chair of the Meeting, the number of Board members, Board and committee fees, the election of Board members and the Chair of the Board, fees for the auditor and the election of the auditor, as well as any proposals for changes to the Nomination Committee's instructions. The Annual General Meeting is scheduled to take place on April 28, 2026, at Zinkgruvan in Askersund.

Shareholders who wish to submit proposals to the Nomination Committee may contact the Nomination Committee by email at valberedningen@boliden.com. In order for proposals to be considered, they must be received by the Nomination Committee no later than January 28, 2026.
