Boliden AB is pursuing one of its largest strategic transactions in years with a proposed acquisition of Votorantim SA’s 64.68% stake in Nexa Resources, a deal that would significantly expand the Swedish miner’s zinc and silver production while strengthening its presence in Latin America. The transaction values Votorantim’s holding at approximately $1.31 billion, based on the issue of 0.250 new Boliden shares for each Nexa share, equivalent to about $15.29 per Nexa share. On an implied basis, Nexa would have an equity value of roughly $2.03 billion and an enterprise value of approximately $3.67 billion.
For Boliden, the deal is primarily about scale, resources and geographic diversification. The Swedish group already operates an integrated mining and smelting business focused on zinc, copper, lead and precious metals across Europe. Nexa would add major mining and processing operations in Brazil and Peru, potentially creating a combined group with 12 mining units and eight smelters. Based on trailing 12-month figures, the enlarged company would generate approximately SEK136 billion in revenue and around SEK38 billion in EBITDA.
Zinc and Silver Strengthen the Strategic Case
Zinc is at the centre of the transaction. Boliden is already an important European zinc producer, while Nexa operates a large integrated zinc and polymetallic portfolio. The combination could create opportunities to improve concentrate flows, smelter utilisation, procurement and operational efficiency. However, the benefits will need to outweigh the complexity of managing assets spread across Europe and Latin America.
Silver provides another attractive element. Nexa’s polymetallic mines offer significant exposure to silver and lead alongside zinc. This broader commodity mix could help diversify Boliden’s earnings when zinc prices weaken or smelting economics become less favourable. The acquisition also increases Boliden’s exposure to Latin American mineral resources, potentially giving the company access to longer-term resource and mine-life opportunities that complement its more mature European operations.
Equity Deal Limits Immediate Balance-Sheet Pressure
Boliden is initially using shares rather than cash to acquire Votorantim’s controlling stake. Following completion, Votorantim is expected to own approximately 7% of Boliden, allowing it to retain exposure to the enlarged mining group. Boliden plans to make a cash tender offer for Nexa’s remaining minority shareholders.
The company has arranged a $2 billion bridge facility to support the tender process and potential refinancing. This means the ultimate impact on Boliden’s balance sheet will depend heavily on minority participation, refinancing conditions and the level of debt retained after the transaction. While the initial equity consideration limits immediate cash outflows, the second stage could materially increase financing requirements.
Latin America Adds Opportunity and Risk
The Nexa acquisition would significantly broaden Boliden’s geographic footprint, but it would also introduce additional operational and regulatory complexity. Nexa’s assets are subject to different regulatory, tax and labour environments from those governing Boliden’s Nordic operations. Integrating mines, concentrators, smelters, marketing systems and corporate functions across several countries will require careful execution.
Capital allocation will also be closely watched. Boliden will need to balance investment in Nexa’s existing operations with potential expansion projects across the combined portfolio. Excessive spending following a major acquisition could reduce the financial benefits of increased scale. The transaction therefore comes with the familiar challenge of mining M&A: acquiring quality resources is only part of the equation. The buyer must also generate attractive returns from those assets while maintaining financial discipline.
A Larger European Metals Platform
The deal could also have wider significance for Europe’s raw-material supply. Europe remains dependent on imported supplies of zinc, copper and other industrial metals. A larger Boliden, backed by mining assets in Latin America and processing capacity in Europe, would provide the Swedish group with a broader resource base and a stronger position in global base-metals markets.
The acquisition is targeted for completion in Q1 2027, subject to regulatory approvals and support from Boliden shareholders. Until then, investors will focus on the transaction’s financing, regulatory progress and treatment of Nexa’s minority shareholders. If completed successfully, the deal could transform Boliden from a predominantly Nordic integrated miner and smelter into a significantly larger global zinc, silver and base-metals producer. The key challenge will be turning that additional scale into higher shareholder returns without losing the capital discipline that has been central to Boliden’s investment case.
