Simon Trott

Chief Executive, Rio Tinto

Rio Tinto

The internal operator betting that discipline — not deals — wins the copper-and-AI decade.

In the first half of 2026, Simon Trott delivered a set of numbers that felt almost deliberately provocative. Underlying EBITDA rose 28 per cent to $14.8 billion. Free cash flow jumped 75 per cent. Copper, aluminium and lithium together contributed more than half of group earnings for the first time in recent memory. At the same time, Trott's team was already banking $870 million of annualised productivity benefits on the way to a $1.8 billion run-rate by year-end.

The results arrived less than a year after he walked away from a potential combination with Glencore on valuation grounds. To some in the market it looked like excessive caution from a new chief executive. To Trott it was simply consistency. "Sanity over vanity" had been the quiet slogan of his iron-ore years. Now it was the operating principle for the entire group. In an industry still tempted by empire-building, the decision to prioritise returns and operational grip over deal size was itself a statement.

The deeper controversy is cultural. Trott is an internal operator, not a dealmaker imported from outside. He rose through Rio Tinto's commercial and product-group ranks, spent five years fixing the iron-ore business after the reputational damage of Juukan Gorge, and was then handed the whole company. The bet is that the same discipline that stabilised the Pilbara can reshape a diversified major for the copper-and-AI decade without the distractions of transformational M&A.

Simon Trott matters this month because Rio Tinto is the clearest large-cap test of whether a major miner can simultaneously deliver iron-ore cash flows, accelerate copper and lithium growth, and impose genuine capital and cost discipline. The energy transition and the AI infrastructure boom have made copper, aluminium and lithium structurally more important; Trott's early results show those businesses already generating the majority of earnings. At the same time he is running a multi-year productivity programme and signalling portfolio optimisation.

For an international audience focused on energy, business and strategic minerals, Trott represents the operational face of the shift from bulk commodities toward the metals that power electrification and data centres. He is still early in the role, but the first evidence is already visible in the numbers and in the explicit rejection of value-destructive expansion.
