Boliden AB stock (ISIN SE0022415691) closed at SEK 546.80 on Nasdaq Stockholm on September 10, 2026, down 4.27 percent from the previous trading day, reflecting renewed pressure on the mining group after recent news on its Nexa Resources bid and zinc output trends.

Stock reacts to Nexa Resources acquisition plan

According to Finimize on September 10, 2026, Boliden plans to acquire 64.68 percent of Brazil-based Nexa Resources, expanding its footprint in zinc and other base metals while taking control of a Latin American asset portfolio.

As Finimize reports, Berenberg has maintained a Hold rating on Boliden but lifted its price target to SEK 560, suggesting limited upside from the current share price despite the strategic rationale of the Nexa transaction.

Zinc production and share price volatility

Boliden's operational backdrop also shows mixed signals in zinc, a key profit driver. According to Investing.com on September 11, 2026, Boliden's zinc concentrate production declined 16.8 percent quarter-on-quarter in Q2 2026 to 74,200 tonnes, indicating a meaningful short-term drop in volumes.

The same zinc-market commentary from Investing.com highlights that other producers such as MMG reached 106,000 tonnes of zinc output in the first half of 2026, underscoring the competitive landscape in zinc and adding context to Boliden's production trends.

Market reaction has been noticeable. As MSN reported with data from September 10, 2026, Boliden shares fell by a little over 4 percent on the day, placing the miner among the weakest performers on Stockholm's OMXS30 index during a session when sentiment turned negative for cyclical stocks.

The same MarketScreener data set shows that Boliden's current year performance up to September 10, 2026 stands at a gain of 6.13 percent, while the stock has declined 16.77 percent over the past six months, illustrating how the recent Nexa bid and zinc production developments are playing out against a volatile medium-term trajectory.
