Institutional Shareholder Services (ISS) has advised Rio Tinto shareholders to support a proposal to reassess the company's dual-listed structure following pressure from activist Palliser Capital. Palliser is advocating for the merger of Rio Tinto's London and Sydney listings into a single entity in Australia, claiming that the current structure has led to a loss in shareholder value and caused the company's stock to trade at a discount compared to its competitors. ISS, a respected advisory firm, is now suggesting that shareholders vote on April 3 to approve Palliser's request for Rio Tinto to review the situation. ISS's report highlights the potential benefits of consolidation, such as simplifying operations, minimizing conflicts of interest, enhancing strategic flexibility, and narrowing the valuation gap for Plc shareholders. This recommendation from ISS follows a similar stance taken by Glass Lewis, another advisory firm, which also endorsed Palliser's proposal. The opinions of ISS and Glass Lewis often play a key role in influencing investor decisions on important matters such as board memberships and merger approvals.
