Rio Tinto Faces Key Takeover Deadline Amid Operational Moves

Rio Tinto GB0007188757

The British-Australian mining giant Rio Tinto is approaching a significant regulatory milestone. Potential bidders are required to formally declare their intentions or enter a quiet period by February 5, 2026. This development unfolds as the company advances key operational projects in Australia to ensure the longevity of its iron ore output.

Trading on February 2 presented a mixed picture for Rio Tinto's stock. On the London Stock Exchange (LSE), shares closed at 6,802.00 GBX, marking a gain of 0.95%. Conversely, on the Australian Securities Exchange (ASX), the stock declined by 1.04%, finishing the session at 149.98 AUD. In a separate corporate filing on February 2, the company reported a total of 1,256,023,083 ordinary shares of Rio Tinto plc in issue as of January 30, 2026.

The "Put Up or Shut Up" Rule in Focus

Market speculation has been fueled by persistent rumors of a potential acquisition by the commodities conglomerate Glencore. Under UK takeover regulations, the so-called "put up or shut up" rule is now in effect. This mandates that any interested party must make a firm offer by the upcoming deadline or refrain from making a bid for a set period. A merger between these two mining titans would create an entity with a combined market value exceeding $200 billion. To date, no formal proposal has been submitted.

Securing Iron Ore Production with Major Contract

On the operational front, Rio Tinto continues to solidify its core business. The company has awarded a substantial contract, valued at approximately 175 million Australian dollars (around 122 million US dollars), to the Australian contractor NRW Holdings. This agreement covers earthworks for the West Angelas Sustaining Project located in the Pilbara region.

Scheduled to commence in early 2026 and continue through 2027, the project will require a workforce of up to 220 personnel. This investment underscores Rio Tinto's strategic commitment to securing its long-term iron ore production capacity.

Recent Strategic Acquisition

In a move to bolster its aluminum portfolio, Rio Tinto, in partnership with the Aluminum Corp. of China, finalized the acquisition of a majority stake in Companhia Brasileira de Aluminio in late January. The transaction was valued at $902.6 million.

Investor sentiment remains cautious as the market awaits clarity regarding the impending regulatory deadline and any potential corporate actions.
