Rio Tinto Under Pressure to Bid for Teck Resources

Rio Tinto (RIO) is under pressure from activist fund Pallister Capital who have made renewed calls for a Teck Resources counterbid and a unification of Rio Tinto’s dual-listed structure. This pressure adds a new layer to the company’s existing challenges and opportunities

Rio Tinto Urged to Bid for Teck Resources

As of November 3, 2025, Rio Tinto shares traded at $71.74, down $0.45 or 0.62% from the previous day’s close. This decline reflects market uncertainty surrounding the company’s strategic direction amidst activist interventions and potential asset restructuring. Teck Resources (TECK) also saw a slight decrease, trading at $42.92, down $0.165 or 0.38%.

Palliser Capital, holding a stake of less than 1% in Rio Tinto, has urged the company to pursue a counterbid for Teck Resources, advocating for a unified dual-listed structure and a spin-off of its base metals business. Palliser argues that these moves could unlock substantial synergies and attract new investment, potentially creating a copper-focused entity producing 1.3 million metric tons annually. However, Rio Tinto has rejected this proposal, reaffirming its commitment to shareholder value and dismissing Palliser’s claims.

In May 2025, Rio Tinto shareholders overwhelmingly voted against reviewing the company’s dual-listed structure, with over 80% supporting the board’s recommendation to maintain the status quo. The board cited tax considerations and potential value destruction as reasons for resisting unification, despite Palliser Capital’s assertion that it could unlock $28 billion in value for London shareholders.

Rio Tinto is also considering an asset-for-equity swap with Chinese state-owned Chinalco to alleviate governance constraints and enhance strategic flexibility. This potential deal involves Chinalco exchanging a portion of its 11% stake in Rio for interests in specific mining assets, possibly including the Simandou iron ore project and the Oyu Tolgoi copper mine. Such a swap could reduce Chinalco’s stake by 2-3 percentage points, enabling Rio to pursue share buybacks, mergers, and restructuring initiatives without diluting its largest shareholder.

Third-quarter iron ore shipments for Rio Tinto reached 84.3 million tons, slightly below the estimated 85.5 million tons. Despite this, a surge in Chinese demand, boosted by infrastructure stimulus and expectations of global tariffs, has driven iron ore prices to multi-month highs. The company anticipates annual shipments to be at the lower end of its 323–338 million ton guidance, primarily due to disruptions caused by earlier cyclones.

Rio Tinto Analyst Summary

The coming months will be crucial for Rio Tinto as it balances activist demands, strategic realignments, and market dynamics. The company’s ability to navigate these challenges will ultimately determine its future performance and shareholder value.
