Meanwhile, retail sentiment around Rio Tinto’s shares soured into ‘extremely bearish’ territory from ‘neutral’ a day ago.

The acquisition, valued at $6.7 billion, was first announced in October 2024. Rio Tinto agreed to purchase Arcadium in an all-cash deal for $5.85 per share, representing a 90% premium to Arcadium’s closing price of $3.08 per share on Oct. 4, 2024. 

The offer also marked a 39% premium to Arcadium’s volume-weighted average price (VWAP) since its creation in January 2024.

Rio Tinto’s CEO Jakob Stausholm called the acquisition a key milestone in the company’s strategy, stating, “Acquiring Arcadium Lithium is a significant step forward in Rio Tinto’s long-term strategy, creating a world-class lithium business alongside our leading aluminium and copper operations to supply materials needed for the energy transition.”

Arcadium’s stock has dipped by over 16% in the last year, while Rio Tinto’s shares fell by over 12% during the same period.
