Rio Tinto Group (ASX:RIO) will be in focus Thursday as the mining giant holds its 2025 annual general meeting at 9:30 am Australian Western Standard Time (AWST), according to the company's website.

Among the key resolutions up for a vote at the meeting is a proposal from activist hedge fund Palliser Capital calling for an independent review of Rio Tinto's dual-listed company structure.

Palliser, a minority shareholder in Rio Tinto's London stock, is pushing for a review to unify the company under a single Australian entity, citing that 80% of its earnings come from Australia.

The meeting will be held both in person at the Perth Convention and Exhibition Centre and online via the Lumi platform.
