There is no clear universal winner among Fortescue, BHP and Rio Tinto. Fortescue offers more concentrated iron ore exposure in the figures cited here, while BHP and Rio Tinto report broader commodity portfolios. Which one fits depends on the exposure you want, the risks already in your portfolio, your investment horizon and the price you pay.
How the three miners differ
All three are large miners with material iron ore operations, but their reported business mixes are not identical. Fortescue’s cited FY26 results centre on iron ore. BHP and Rio Tinto report broader commodity portfolios; Rio’s reporting includes copper, aluminium, bauxite and lithium as well as iron ore. Wider commodity exposure can alter how a miner responds to different markets, but it does not eliminate commodity, operating or share-price risk.
The numbers below are company-reported and cover different periods and definitions. They are useful for understanding each company’s disclosures, not for declaring a like-for-like winner.
| Company | Reported operating and financial figures | What the figures tell you |
|---|---|---|
| Fortescue | For FY26, Fortescue reported 201.3 million tonnes (Mt) of iron ore shipments, US$3.5 billion underlying net profit after tax, US$3.2 billion free cash flow and a fully franked A$1.08 dividend per share. (Fortescue Investor Centre, FY26.) | A snapshot of a strong reported year and substantial iron ore exposure; these figures alone do not establish future operating performance or dividend sustainability. |
| BHP | For the year ended 30 June 2025, BHP reported 263 Mt of iron ore production, WAIO unit costs of US$18.56 per tonne and iron ore revenue of US$22.919 billion. For FY2026, it expected WAIO unit costs of US$18.25–19.75 per tonne, assuming AUD/USD of 0.65. (BHP Annual Report 2025.) | The historical figures describe FY2025; the cost range is guidance, not a result. The stated exchange-rate assumption matters when interpreting the guidance. |
| Rio Tinto | For 2025, Rio Tinto reported US$25.4 billion underlying EBITDA, Pilbara iron ore production of 327.3 Mt on a 100% basis, and total dividends of 402 US cents per share. (Rio Tinto Annual Report on Form 20-F 2025.) | The production figure is explicitly on a 100% basis. Underlying EBITDA, production and dividends are different measures and should not be treated as interchangeable indicators. |
What could make each share fit
Fortescue: concentrated iron ore exposure
Fortescue may suit an investor who specifically wants exposure centred on iron ore rather than a broader mix of mining commodities. Its FY26 headline figures—shipments, profit, free cash flow and dividend—show what the company reported for that year, but do not establish that those results will recur. A concentrated exposure can also leave an investor more reliant on the conditions affecting that commodity and the company’s operations.

BHP: iron ore scale within a broader portfolio
BHP’s disclosures combine large iron ore operations with a wider portfolio. Its FY2025 WAIO cost figure and FY2026 cost guidance offer a view into one part of the business, not a harmonized cost comparison against the other two miners. The guidance is conditional on an AUD/USD assumption of 0.65; actual outcomes may differ.
Rio Tinto: iron ore alongside other commodities
Rio Tinto’s reporting spans iron ore and other commodities, including copper, aluminium, bauxite and lithium. In its 19 February 2026 results release, Rio attributed an 8% uplift in copper-equivalent production to the ongoing ramp-up of the Oyu Tolgoi underground copper mine and record iron ore production since April from its Pilbara operations. The release also reported a 60% payout ratio and a US$6.5 billion ordinary dividend. These are company statements about its reported results, not a forecast of future production or distributions.
Costs, scale and resilience: what cannot be ranked here
The reported production figures do not use one common period or basis: Fortescue’s figure is shipments for FY26, BHP’s is production for FY2025, and Rio’s Pilbara production is stated for 2025 on a 100% basis. Shipments and production are not the same measure. Likewise, the figures are reported in different currencies and include different financial metrics. A higher number in one row does not by itself mean a better-performing or more resilient company.
BHP supplies WAIO unit costs for FY2025 and a FY2026 expectation, but the cited material does not provide harmonized, current unit-cost figures for all three. It therefore does not support a definitive cost-leader ranking. Comparing resilience would also require considering the different commodity mixes, operating performance, currency movements and capital demands rather than relying on one cost measure.

Dividends: compare the policy and the basis, not just the headline
Fortescue reported a fully franked A$1.08 per-share dividend for FY26. Rio Tinto reported total dividends of 402 US cents per share for 2025 and, in its February 2026 results release, a US$6.5 billion ordinary dividend and a 60% payout ratio. These figures cover different periods and currencies, and the descriptions and tax treatment are not the same. BHP’s dividend amount is not stated in the figures compared here.
A past dividend is not a promise of future income. If income is a key reason for considering a miner, examine the company’s distribution policy and cash generation alongside the dividend record, and consider how a change in commodity conditions could affect distributions. Australian tax treatment and franking may also matter to an individual investor; the quoted figures alone cannot establish an investor’s after-tax return.

A delayed Stock Analysis quote put Fortescue (ASX: FMG) at A$16.19 at the 2 October 2026 close, with a trailing P/E of 12.03. That is one third-party snapshot for one company on one date. Comparable BHP and Rio Tinto valuation figures on the same date, listing basis, currency and accounting basis were not established here, so this figure cannot support a claim that Fortescue is cheaper or more expensive than either peer.
For a meaningful comparison, use a common date and a consistent measure—such as trailing or forward earnings or cash flow—and check which listing and currency each figure uses. A valuation multiple is only one input: it does not predict returns or make a share suitable for a particular portfolio.

A practical way to decide what fits
- Check your existing exposure. Consider whether you already hold miners, iron ore-linked investments or other assets whose performance may be affected by similar commodity or currency movements.
- Choose the exposure you want. Decide whether concentrated iron ore exposure or a broader mix of commodities better matches your investment objective. Broader exposure changes the mix of risks; it does not remove them.
- Assess the risks you can tolerate. Consider your time horizon and capacity to withstand share-price and commodity swings. Company-level results cannot determine an appropriate allocation for you.
- Compare current disclosures on matching terms. Align reporting periods, production bases, currencies and definitions. Separate historical results from guidance, and check assumptions such as BHP’s stated exchange rate for its FY2026 WAIO cost range.
- Evaluate distributions and valuation separately. Look at dividend policy and cash generation without treating past payments as guaranteed, then compare valuation using a common date and method before drawing conclusions.
Verdict
Fortescue is the more concentrated iron ore choice in the evidence presented; BHP and Rio Tinto offer broader reported commodity exposure. The available figures do not establish a single best miner, a definitive cost leader or a valid peer valuation ranking. Choose based on the exposure and risk profile you want, how it fits your existing holdings, and a like-for-like assessment of current valuation.
