Founded in 1873 and headquartered in London, United Kingdom, Rio Tinto is part of the ASX 200.

Key numbers explained

• 164.85 AUD is the latest price for RIO on the ASX.
• The trailing P/E ratio (15.7) divides the current share price by the last 12 months of earnings per share (10.5 USD); a lower number can suggest the stock is cheaper relative to earnings, but it is best compared with peers like BHP (BHP).
• The forward P/E ratio (13.5) uses expected future earnings, which can be more relevant for valuation than the trailing figure.
• The dividend yield (4.02%) shows the annual dividend as a percentage of the share price; the ex-dividend date is Aug 13, 2026, and 55% of earnings are paid out as dividends.
• Beta (0.66) measures sensitivity to market moves; a value below 1 suggests RIO has historically been less volatile than the broader market.
• Price-to-book (2.87) compares the share price to the company's book value per share.
• Return on equity (19.3%) indicates how effectively the company generates profit from shareholders' equity.
• The debt-to-equity ratio (31.9%) shows the proportion of debt relative to equity, which helps assess financial leverage.

What to watch

Rio Tinto's performance is tied to global commodity prices, particularly for iron ore, copper, aluminium, and lithium. Mining operations can be affected by geopolitical events, regulatory changes, and environmental policies in the regions where it operates. Currency movements, especially the AUD/USD rate, can influence reported results for international investors. Production costs, labour relations, and the pace of capital expenditure on new projects are also relevant factors. For those tracking the broader Australian mining space, peers such as Capstone Copper (CSC), Newmont (NEM), and Sandfire Resources (SFR) offer useful comparison points.
