There may be faint disappointment in Pretoria at the appointment of another white man to chair Anglo American, South Africa’s flagship business, but the blow is much worse in Zug, the head office of Xstrata, the miner that wants to merge with Anglo. Xstrata had sensed weakness at Anglo, and as stories undermining Cynthia Carroll, Anglo’s chief executive, started circulating, her opposite number, Mick Davis, saw his chance. As the Anglo share price wilted following its unwelcome decision to scrap the dividend, he proposed what he disingenuously called a “merger of equals”. The market values may have been equal at that moment, but they are not now, with Anglo valued at 20 billion pounds against Xstrata’s 17 billion pounds. The news that John Parker is to join the board and become chairman next month will reassure Anglo’s shareholders that the company is serious about addressing their concerns about how the business is being run. Parker is a Northern Irishman of great charm whose easy-going manner conceals an ability to encapsulate and get to the kernel of complicated arguments. His arrival changes the dynamics of the international mining business, and makes it much more likely that Anglo will take an active, rather than passive, role in the consolidation that the market appears to be demanding. The appointment probably puts Anglo beyond Davis’ reach, although he should not be underestimated. Michael Rawlinson at brokers Liberium has already remarked on the parallels with BHP Billiton: “BHP shareholders initially resented the terms of the merger, but eight years on it is clear that the cultural renewal…has created a stand out industry leader.” Davis could also promise the South Africans further local involvement, arguing that its record over black empowerment is better than Anglo’s. Yet even that might not be enough, now that a white knight is riding in to take charge at Castle Anglo.
