Lower commodity prices and higher operating unit costs were the principal pressures on EBITDA. Price movements reduced EBITDA by $1.5bn and operating cash unit costs by $1.4bn; higher volumes and weaker local currencies provided partial offsets. Operating cash flow also reflected a $0.9bn working-capital increase. The underlying-earnings effective tax rate was 30%, versus 26% in 2022.
Cash and cash equivalents were $9.7bn, with approximately $0.9bn of other short-term investments. Total borrowings were $13.0bn and lease liabilities $1.4bn; net gearing was 7%. Financing liabilities, excluding net-debt derivatives, were $14.4bn with an approximately 12-year weighted average maturity. The company reported a strong balance sheet and said its financial policy is anchored around maintaining a single-A credit rating.
Segments and material changes
| Segment | 2023 revenue | 2023 underlying EBITDA | Year-over-year EBITDA change |
|---|---|---|---|
| Iron Ore | $32.2bn | $20.0bn | +7% |
| Aluminium | $12.3bn | $2.3bn | -38% |
| Copper | $6.7bn | $1.9bn | -26% |
| Minerals | $5.9bn | $1.4bn | -42% |
Iron Ore benefited from higher realised prices and increased Pilbara shipments, which rose 3%; its Pilbara underlying FOB EBITDA margin was 69%. Aluminium earnings fell amid lower realised prices and premiums, despite 9% higher aluminium production. Copper was affected by the Kennecott smelter and refinery rebuild, lower refined volumes and higher unit costs; mined copper production rose 2%. Minerals faced weaker demand and lower production in several products, including a 28% decline in diamonds production.
Group copper-equivalent production increased just over 3%. Pilbara iron ore production was 331.5Mt, aluminium production 3.272Mt and mined copper production 620kt. Net impairment charges were $0.7bn after tax, mainly relating to Queensland alumina refineries. The company also reversed previously impaired Simandou assets after reaching key project agreements. Closure-estimate charges were a major excluded item, including an $850m update related to Energy Resources of Australia.
Outlook, risks and unusual items
- 2024 production guidance: Pilbara iron ore shipments 323–338Mt; mined copper 660–720kt; refined copper 230–260kt; aluminium 3.2–3.4Mt; alumina 7.6–7.9Mt; bauxite 53–56Mt; IOC iron ore pellets and concentrate 9.8–11.5Mt; and titanium dioxide slag 0.9–1.1Mt. These are operating forecasts, not earnings guidance.
- Management expects fixed costs to be broadly flat in 2024 and sustaining capital expenditure of about $4bn per year. Capital expenditure is expected to rise in coming years as growth and decarbonisation projects advance.
- Simandou in Guinea is estimated to require $6.2bn of Rio Tinto investment for its mine and share of infrastructure, subject to approvals and partner conditions. First production is expected in 2025, with a ramp-up over approximately 30 months; stated Rio Tinto share of annual capacity is 27Mt.
- Other growth priorities include ramping up Oyu Tolgoi underground production, the $1.1bn AP60 aluminium smelter expansion, Kennecott underground development and the Rincon lithium starter plant. Targets and project schedules depend on technical delivery, approvals, funding and community engagement.
- The company targets a 50% reduction in Scope 1 and 2 emissions by 2030 from its adjusted 2018 baseline and net zero by 2050. It estimates $5–6bn of decarbonisation capital investment through 2030. 2023 Scope 1 and 2 emissions were 32.6Mt CO2e; Scope 3 emissions were 578.1Mt CO2e.
- Material risks include commodity-price and foreign-exchange volatility, operating cost inflation, project delays and cost overruns, climate-transition and physical risks, permitting and geopolitical uncertainty, cybersecurity, safety, closure obligations and relationships with communities and Indigenous Peoples. Closure provisions rose to $17.2bn from $15.8bn.
- Four Diavik colleagues and two flight crew died in a plane crash in January 2024. The incident occurred after the reporting year; authorities were investigating. Rio Tinto reported no fatalities at managed operations during 2023.
- Other notable matters include the February 2024 dismissal by the Federal Court of Australia of Rusal entities’ case concerning QAL alumina supply; the decision’s impacts were still being assessed. Rio Tinto also disclosed an ongoing Australian Federal Police investigation relating to 2011 Simandou consultant payments, after resolving an SEC matter in 2023.
Most important facts for investors to verify
- Whether commodity prices, operating costs and working capital support forecast cash generation and the 2024 operating guidance.
- Delivery, total cost, financing and approval conditions for Simandou, Oyu Tolgoi, AP60 and other major projects.
- Basis and sensitivity of the $17.2bn closure provision, particularly the Ranger rehabilitation estimate and future study updates.
- Whether decarbonisation targets are achievable on the stated timetable and within the revised $5–6bn capital estimate.
- Developments in safety investigations, the QAL dispute, the Simandou investigation and other material legal or regulatory matters.
- Underlying-earnings adjustments and the reconciliation of non-IFRS measures to IFRS results; the filing identifies substantial impairment, closure and other excluded items.
