Rio Tinto, the $160 billion global mining giant, has successfully resisted an activist investor's push to review its dual-listed structure, with shareholders overwhelmingly voting against the proposal. The London-based hedge fund Palliser Capital had sought to unify the company's listings under a single Australian entity, arguing that the current structure is outdated and could unlock significant value for shareholders. However, less than 20% of the votes cast at the annual general meetings supported the review, falling short of the threshold required under UK corporate governance rules to mandate further consultation.

The outcome represents a significant victory for Rio Tinto's board, which had strongly opposed the proposal, citing potential tax costs in the mid-single digit billions of US dollars and asserting that unification is not in the best interests of shareholders or the company as a whole. The board's stance was supported by a wide consultation with shareholders, who ultimately agreed that the dual-listed structure should remain in place. This decision underscores the challenges activist investors face when attempting to sway large, established corporations with complex global operations.

Palliser Capital's campaign had drawn parallels with BHP's decision to move its primary listing to Sydney in 2022, following pressure from activist investors. However, Rio Tinto's shareholders, particularly those holding UK-listed stock which comprises about 77% of the investor base, showed little appetite for change. The Australian-listed shares, trading at a premium of about 25%, reflect the tax advantages available to Australian shareholders, a factor that may have influenced the voting outcome.

The rejection of Palliser's proposal also highlights the broader debate about the future of London's stock market, which has seen several high-profile companies consider or execute moves away from the UK. Despite these challenges, Rio Tinto's decision to maintain its dual-listed structure signals confidence in the current setup, at least for the foreseeable future. The company's ability to fend off the activist campaign may serve as a case study for other corporations facing similar pressures, demonstrating the importance of board-shareholder alignment in corporate governance decisions.

A major outage at Amazon Web Services has disrupted operations for numerous popular applications and platforms globally, affecting millions of users. The cloud computing infrastructure failure began early Monday morning, with users reporting widespread issues accessing services including Snapchat, Duolingo, Zoom, and various gaming platforms. Amazon confirmed it was investigating increased error rates and latency across multiple AWS services, though the company has not yet identified the root cause of the system failure.

The disruption appears to have originated with servers hosted in the US-EAST-1 region, according to initial reports. This triggered a cascade effect that impacted AWS infrastructure supporting millions of websites and applications worldwide. Downdetector, a platform that monitors service outages, reported receiving over four million problem reports in a single morning—more than double the typical weekly volume—indicating the scale of the disruption across affected services.

Among the services experiencing significant operational problems are communication platforms like Zoom, Signal, and Slack; gaming services including Roblox, Fortnite, and PlayStation Network; social media applications such as Snapchat; and financial services from banks including Lloyds and Bank of Scotland. Streaming platforms Prime Video and Crunchyroll, along with educational tool Duolingo and design platform Canva, have also been affected by the cloud service failure.

The outage has manifested differently across regions, with Amazon's own websites remaining operational in Europe while still experiencing service-specific errors. AWS engineers are actively working to mitigate the issues and restore normal operations. The company has committed to providing regular updates as they work to resolve the widespread service disruption that has highlighted the internet's heavy reliance on cloud infrastructure providers.
