The share is listed in the Large Cap segment of NASDAQ Stockholm. www.boliden.com Boliden’s rationale for the Transaction and financial effects • An excellent fit and growth opportunity in Latin America: Boliden's strong European experience coupled with Nexa’s notable Latin American operations are expected to create a strong zinc business with a significant silver component that leverages local know-how and operational excellence in attractive mining jurisdictions. As a large, long-term shareholder of Boliden, Votorantim, one of Latin America’s largest investment holding companies, will provide valuable regional experience. • Creation of a geographically diversified, resilient, and growth-oriented business: Boliden will combine its European base and precious metals mining and smelting operations with Nexa’s Latin American assets. Boliden's century-long track-record combined with Nexa’s 65+ year history of regional expertise provides a proven foundation for future sustainable and long-term value creation, underpinned by unwavering commitment to safe and responsible business practices. The Transaction allows Boliden to leverage its long-standing technical expertise and operational excellence in unlocking additional value from Nexa’s growth pipeline. • Accretive for Boliden’s shareholders: The Transaction is expected to be immediately accretive to Boliden's earnings per share and contributes >8% to EPS.8 Following Closing, Boliden (including through Nexa) will operate a portfolio of 12 mining units and 8 smelter units across Europe and Latin America. Subject to receipt of all regulatory approvals, the Transaction is expected to lead to a significant increase in Boliden’s production of finished metals as well as metals in concentrate. Nexa will be fully consolidated in Boliden’s financial statements from Closing, with the remaining minority Nexa shares recognized as non-controlling interest in Boliden’s financial statements. In the twelve-month period ending June 30, 2026, Boliden and Nexa had a combined consolidated revenue of approximately SEK 136 billion, and EBITDA of approximately SEK 38 billion.9 As of June 30, 2026, Boliden reported a net debt-to-equity ratio of 24%. Assuming that the Transaction would have been closed as of June 30, 2026, Boliden’s combined consolidated net debt-to-equity would have been approximately 33%.10 Boliden’s dividend policy and financial targets remain unchanged following the Transaction . Conditions to Closing Closing is conditional on Boliden’s shareholders authorizing Boliden’s Board of Directors to issue the consideration shares to Votorantim (to be implemented by way of an issue -in-kind). Boliden’s Board of Directors intends to convene an EGM for this purpose. Approval of the issue authorization requires support by Boliden shareholders representing a simple majority of votes cast at the EGM. Through the issuance of the consideration shares in the Transaction, the number of shares in Boliden will increase from 284,225,454 to 305,639,236, representing a dilutive effect of approximately 7.0%. Under the transaction agreement, Votorantim has the right to propose a representative for election to Boliden’s Board of 8 2026E; based on Nexa broker consensus, Boliden estimates and 7.0% share dilution . 9 Assumes full consolidation of Nexa’s earnings according to IFRS; Based on an average rolling 12 months USD to SEK exchange rate of 9.36 on June 30, 2026. 10 Combined net debt to equity ratio defined and calculated as the sum of Boliden current net debt plus Nexa current net debt divided by Boliden’s current book value of equity plus Nexa implied equity value (on a 100% basis) as of June 30, 2026.

Closing is also conditional upon approval by Nexa’s EGM for appointment of a new Nexa Board of Directors. Following Closing, Boliden currently expects that Nexa would have a Board of seven Directors, of which four Directors would be affiliated with Boliden. Closing is also subject to competition and other regulatory approvals, as well as other customary closing conditions. Boliden currently expects that the Transaction will close during the first quarter of 2027. Financing for the Transaction Boliden has secured a fully committed bridge financing facility totalling USD 2.0 billion in support of the Transaction. The facility provides funding flexibility to address potential financing requirements of the VTO for the remaining Nexa shares, potential financing requirements of the mandatory tender offers for shares in certain of Nexa’s Peruvian subsidiaries, and to pro rata fund potential refinancing requirements within Nexa. Boliden expects to determine the appropriate long-term financing structure following Closing. Post-Closing Nexa governance matters Boliden and Nexa have entered into an agreement, to become effective as of Closing, governing the rights of Boliden as a controlling shareholder of Nexa, including customary governance, shareholder rights arrangements and rights for SEC registration of share resales. The agreement also obligates Boliden to commence the VTO following Closing (as further described below). In addition, Boliden has agreed, subject to certain exceptions, that additional acquisitions of Nexa shares or facilitation of Nexa change of control transactions for a period of three years after Closing requires the consent of an independent and disinterested committee of the Nexa Board of Directors. Following Closing, Nexa will continue to exist as a separate legal entity organized under the laws of Luxembourg. Nexa’s shares are and will continue to be listed on the NYSE and Nexa will continue to be subject to reporting obligations under the U.S. Securities Exchange Act of 1934, as amended (the “U.S. Exchange Act”). Nexa is a foreign private issuer (as defined under the U.S. Exchange Act) and is therefore exempt from certain reporting and listing requirements that would apply to U.S. domestic companies. Nexa also relies on the controlled company exception under the NYSE listing rules, and is expected to continue to do so following Closing. Boliden will govern Nexa through Nexa’s Board of Directors and existing Nexa management is expected to largely remain in place. Nexa will be reported by Boliden as a separate segment.
