Is RIO a Buy? What to Consider in 2026
Last updated July 2026
Short answer
The bull case for Rio Tinto (RIO) rests on Iron ore scale plus Simandou: The Pilbara iron ore system remains one of the lowest-cost, highest-margin operations in mining and drives the bulk of group earnings. Revenue (2025) is ~$57.6B. If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: Rio's fortunes are tightly linked to iron ore prices, which hinge on Chinese steel demand and property construction, so a slowdown there hits earnings and the dividend directly. Whether RIO is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.
Rio Tinto is a global mining group that digs, processes, and ships the raw materials behind steel, power grids, and batteries. Iron ore from its Pilbara operations in Western Australia is still the profit engine, generating the majority of earnings, while the company also produces aluminum and bauxite, copper (including from the Oyu Tolgoi mine in Mongolia), and, after its 2025 acquisition of Arcadium, lithium. Its two marquee growth projects are the giant Simandou iron ore mine in Guinea, which made its first shipment in late 2025, and a lithium business it aims to scale toward 200,000 tonnes of lithium carbonate equivalent by 2028. RIO shares are American Depositary Receipts representing the London-listed Rio Tinto plc, so U.S. investors get the same underlying economics with dollar-denominated trading. The investment picture is classic large-cap resources: enormous cash generation at the top of the cycle, a policy of paying out a high share of earnings as dividends, and a valuation that stays modest because the market prices in the volatility of commodity prices, especially iron ore tied to Chinese steel demand. In 2025 the company grew revenue and EBITDA but saw net debt jump after funding the Arcadium deal, and reported earnings that were roughly flat year over year. For a shareholder, the appeal is a well-run, diversified miner with a large yield and optionality on copper and lithium; the catch is that the same asset can swing hard when metals prices move.
What's the case for buying RIO?
1. Iron ore scale plus Simandou
The Pilbara iron ore system remains one of the lowest-cost, highest-margin operations in mining and drives the bulk of group earnings. The new Simandou mine in Guinea, which shipped its first ore in late 2025, is targeted to ramp toward roughly 27 million tonnes a year of Rio's share by mid-2028, adding a second high-grade iron ore source. This anchors the cash flow that funds both the dividend and growth spending.
2. Copper growth for electrification
Copper is Rio's clearest structural growth story, positioned for grid buildout, electric vehicles, and data-center demand. The Oyu Tolgoi underground mine in Mongolia is ramping toward major output, helping lift copper-equivalent production, which rose about 8% in 2025. Management frames copper as a decade-long expansion lever alongside iron ore's steadier base.
3. Lithium optionality via Arcadium
The 2025 Arcadium acquisition made Rio a top-tier lithium producer overnight, with a stated goal of exceeding 200,000 tonnes of lithium carbonate equivalent capacity by 2028. It is a longer-dated bet on battery demand that diversifies the company away from steelmaking materials. Near-term earnings contribution is modest given weak lithium prices, so this is optionality more than a current profit driver.
4. Large, policy-driven dividend
Rio targets paying out a high proportion of underlying earnings, and the 2025 full-year ordinary dividend of about $6.5 billion reflected a roughly 60% payout ratio. The resulting yield, around 4% at mid-2026 prices, is a core part of the total-return case. Because the payout scales with earnings, income can shrink in a commodity downturn.
What are the risks to RIO?
Rio's fortunes are tightly linked to iron ore prices, which hinge on Chinese steel demand and property construction, so a slowdown there hits earnings and the dividend directly. Net debt rose sharply in 2025 after funding the Arcadium lithium deal, and lithium prices have been weak, so that investment may take years to pay off. Large projects like Simandou and Oyu Tolgoi carry execution, cost-overrun, and geopolitical risk across Guinea and Mongolia. The company also faces environmental, permitting, and community-relations scrutiny after past controversies, plus periodic merger and consolidation speculation (including reported talks involving Glencore) that could reshape the business. As with any miner, currency and energy-cost swings add further volatility.
How is RIO valued? (as of JULY 2026)
Snapshot for RIO as of July 2026, sourced from Yahoo Finance and may be delayed. Valuation figures move with price and earnings; verify the current numbers with your broker before deciding.
- Revenue (2025): ~$57.6B
- Underlying EBITDA (2025): ~$25.4B
- Underlying earnings (2025): ~$10.9B
- Net debt: ~$14.4B
- Market cap: ~$165B to $180B
- Dividend yield: ~4.3%
Revenue and EBITDA both grew in 2025, but reported profit slipped and net debt roughly tripled after the Arcadium lithium acquisition. Shares traded around the low-to-mid $90s at mid-2026 on a trailing P/E of roughly 15, a discount that reflects commodity-cycle risk. The full-year dividend of about $6.5 billion at a roughly 60% payout keeps the yield near 4%.
How do you decide if RIO is a buy?
Rather than asking whether RIO is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold RIO indirectly through an index or sector ETF before adding more.

If you believe that narrative continues, the call is about sizing RIO sensibly and checking overlap with what you own; if you doubt it (the risk: rio's fortunes are tightly linked to iron ore prices, which hinge on Chinese steel demand and property construction, so a slowdown there hits earnings and the dividend directly.), it is not for you. Decide from the thesis, not the ticker. Walnut is not an investment adviser.

Is RIO a good stock to buy right now?
+
This is not investment advice, and Walnut is not an investment adviser. The bull case is scaled, low-cost iron ore, a growing copper and lithium franchise, and a roughly 4% dividend at a modest valuation near 15 times earnings. The bear case is heavy dependence on Chinese steel demand, higher net debt after the Arcadium deal, weak lithium prices, and project and geopolitical risk. Whether it fits you depends on your goals, time horizon, and tolerance for commodity-cycle swings.
What does Rio Tinto do?
+
Rio Tinto is one of the world's largest diversified mining companies. It produces iron ore (mainly from the Pilbara in Western Australia), aluminum and bauxite, copper (including from Oyu Tolgoi in Mongolia), and, since 2025, lithium. It sells these materials to steelmakers, manufacturers, and battery producers worldwide.
Is RIO an ADR, and what does that mean?
+
Yes. RIO shares on the NYSE are American Depositary Receipts representing the London-listed Rio Tinto plc. That lets U.S. investors buy and hold the stock in dollars through a normal brokerage account, with the same underlying business economics. Dividends are paid in dollars, though currency conversion and foreign withholding can affect the net amount.
Does Rio Tinto pay a dividend?

Yes, and it is a large one. Rio targets paying out a high share of underlying earnings, and the 2025 full-year ordinary dividend was about $6.5 billion, roughly a 60% payout ratio, translating to a yield near 4% at mid-2026 prices. Because the dividend scales with earnings, it can rise or fall with commodity prices.
