(a)The Group profit before tax includes profit after tax of equity accounted units. Consequently, the tax effect on the

profit from equity accounted units is included as a separate reconciling item in this prima facie tax reconciliation.

(b)As a UK headquartered and listed Group, the reconciliation of expected tax on accounting profit to tax charge uses

the UK corporate tax rate to calculate the prima facie tax payable. Rio Tinto is also listed in Australia, and the

reconciliation includes the impact of the higher tax rate in Australia where a significant proportion of the Group's

profits are currently earned. The impact of other tax rates applicable outside the UK and Australia is also included.

The weighted average statutory corporate tax rate on profit before tax is approximately 28% (30 June 2025: 30%).

(c)Current-period unrecognised deferred tax assets include operating losses and other costs incurred by the Group for

which no tax benefit is currently recognised due to uncertainty regarding the availability of suitable taxable profits in

future periods.

(d)Other items includes less than US$1 million (30 June 2025: less than US$1 million) current tax expense related to

Pillar Two measures; the global minimum tax of 15% formulated by the Organisation for Economic Co-operation

and Development (OECD).
