South32 shares (ASX: S32) rallied to their highest level in nearly three years after the diversified miner delivered a robust second-quarter production report, highlighting significant output gains across its manganese, alumina, and aluminium operations.
The S32 share price closed 5.26% higher at A$4.40, having touched an intraday peak of A$4.44 during the session. The advance pushed the stock to levels not seen since April 2023, extending the company’s year-to-date gains and marking a decisive breakout from the trading range that had characterised much of the previous year. The rally came on elevated volumes as markets responded enthusiastically to the operational update.
Core Details
South32’s second-quarter FY26 production report revealed substantial output improvements across its key commodity portfolio. Manganese production emerged as the standout performer, with a 58% jump overall driven by a 26% increase at the Australia Manganese operation to 806,000 wet metric tonnes and a 4% rise at South Africa Manganese to 506,000 wet metric tonnes.
The company also reported a 3% increase in alumina production, supported by record output at its Brazil Alumina facility, while aluminium production climbed 2% with the Hillside Aluminium smelter operating at full technical capacity. These gains underscored the operational consistency that has become a hallmark of South32’s recent performance.

The miner maintained its FY26 production guidance across all operated assets, with first-half operating unit costs tracking in line with previous forecasts. This operational discipline comes as the company continues to execute on its capital management programme, which was extended by 12 months to September 11, 2026, with US$144 million remaining to be returned to shareholders through buybacks.
South32 also declared a fully-franked interim ordinary dividend of US$154 million, or US 3.4 cents per share, reinforcing its commitment to shareholder returns despite ongoing capital deployment into growth projects.
Strategic Positioning
The company has been actively reshaping its portfolio to capitalise on the global energy transition. The completion of the Cerro Matoso nickel operation divestment has streamlined the business, while the US$2.16 billion investment in the Hermosa project’s Taylor zinc-lead-silver deposit in Arizona positions South32 to benefit from growing demand for critical minerals. First production from Hermosa is expected in the second half of FY27.
In the first half of FY25, South32 reported a 44% increase in underlying EBITDA to US$1 billion, driven by improved commodity prices and strong operational execution. CEO Graham Kerr stated: “We continued to deliver consistent operating results, with FY26 production guidance maintained across our operated assets and first half operating unit costs tracking in line with guidance.”
Not all analysts share the same enthusiasm for South32’s prospects. In November 2025, Jefferies downgraded the stock from ‘Buy’ to ‘Hold’ with a price target of A$3.20, citing concerns about potential pressure on the aluminium business from Indonesian supply chain developments that could undermine pricing support previously provided by China’s smelting capacity constraints.
The divergence between current market pricing and some analyst targets highlights the tension between South32’s operational execution and broader commodity market uncertainties. While the company has demonstrated its ability to deliver consistent production growth and maintain cost discipline, its exposure to aluminium and alumina markets remains a potential vulnerability if global supply dynamics shift unfavourably.
The manganese business, however, appears to be firing on all cylinders, with production volumes suggesting strong demand fundamentals for the steelmaking ingredient. Markets will be watching closely to see whether this momentum can be sustained through the remainder of the fiscal year.
Bull Case:
- Manganese production surged 58%, demonstrating strong operational leverage to commodity demand
- Maintained FY26 guidance with costs tracking in-line signals operational consistency
- Hermosa project provides critical minerals exposure aligned with energy transition trends
Bear Case:
- Jefferies downgrade highlights aluminium market vulnerability from Indonesian supply chain expansion
- Current share price trades well above A$3.20 analyst target, suggesting limited upside
- Commodity price volatility could pressure margins despite strong production volumes
South32’s strong operational performance and disciplined capital allocation have clearly resonated with markets, driving shares to multi-year highs, yet the company faces headwinds in key segments that could test investor conviction as 2026 progresses and the Hermosa development timeline advances.
