GLC vs BHP vs Rio Tinto: Which Mining Giant Should Australian Investors Choose?

Iron ore, copper and trading create different risk profiles for BHP, Rio Tinto and Glencore, now listed on the ASX. Here is how the three major mining companies compare based on their recent financial performance, asset composition and growth strategies.

Glencore (ASX: GLC) began trading on the Australian Securities Exchange today, bringing the Switzerland-based metals and minerals company alongside established competitors BHP (ASX: BHP) and Rio Tinto (ASX: RIO).

The listing comes as copper becomes increasingly important to the mining industry, while all three companies report developments across their operations and financial performance.

BHP vs Rio Tinto vs Glencore: Financial Performance

BHP (ASX: BHP)

BHP is the largest of the three companies by market capitalisation, at approximately US$210–220 billion.

For the financial year ended 30 June 2026, BHP reported:

• Revenue: US$58.8 billion, up 15%.

• Underlying EBITDA: US$32.9 billion, up 27%.

• Underlying attributable profit: US$13.2 billion, up 30%.

• Net operating cash flow: US$21.8 billion.

Copper contributed a record US$18 billion to underlying EBITDA, accounting for more than 50% of the group's total for the first time.

Rio Tinto (ASX: RIO)

Rio Tinto is the second-largest company, with a market capitalisation of approximately US$150–160 billion.

For the six months ended 30 June 2026, the company reported:

• Underlying EBITDA: US$14.8 billion, up 28%.

• Free cash flow: US$3.8 billion, up 75%.

• Interim ordinary dividend: US$3.4 billion.

Copper, aluminium and lithium accounted for more than half of underlying EBITDA, highlighting the growing contribution of metals beyond iron ore.

Glencore (ASX: GLC)

Glencore is the smallest of the three by market capitalisation, typically estimated at US$70–90 billion.

During the first half of 2026, the company reported:

• Adjusted EBITDA: US$10.1 billion, up 86%.

• Industrial adjusted EBITDA: US$6.5 billion, up 72%.

• Marketing adjusted EBITDA: US$3.3 billion, up 142%.

Glencore subsequently increased its 2026 marketing adjusted operating profit forecast to more than US$5 billion, supported by volatile energy and freight markets.

Commodity Exposure and Operational Focus

BHP: Iron Ore and Copper

BHP's portfolio is primarily focused on iron ore and copper, with additional exposure to metallurgical coal and thermal coal.

Western Australia Iron Ore remains a key part of the business and a low-cost operation. However, copper has become an increasingly important earnings contributor.

In 2026, BHP produced almost 2 million tonnes of copper, continuing the trend from the previous year and highlighting the growth of its copper operations.

Rio Tinto: Iron Ore, Copper and Lithium

Rio Tinto remains heavily focused on iron ore through its Pilbara operations, which continue to deliver substantial volumes.

Its copper growth is increasingly linked to the Oyu Tolgoi underground mine in Mongolia. Production at Oyu Tolgoi increased by 29% compared with the corresponding period in the previous year, up to September 2026.

Rio Tinto is also advancing the Simandou iron ore project in Guinea, which reached an annualised production rate of approximately 10 million tonnes during the September quarter.

Alongside iron ore and copper, the company is expanding its lithium operations, while aluminium remains an important part of its business.

Glencore: Mining and Global Trading

Glencore differs from BHP and Rio Tinto because it combines mining operations with a global marketing and trading business.

Its industrial assets include copper, metallurgical and energy coal, zinc, nickel and other metals.

The marketing and trading arm can generate earnings opportunities during periods of market volatility, giving Glencore a different earnings profile from its larger ASX-listed peers.

The company is also pursuing brownfield copper growth projects and has outlined plans to substantially increase copper production over the longer term. Glencore continues to operate and employ people in Australia.

Balance Sheets and Capital Returns

BHP

BHP ended the 2026 financial year with net debt of less than US$9 billion, well below its target range, supported by strong free cash flow.

The company paid approximately US$8.7 billion in dividends for the 2026 financial year.

Rio Tinto

Rio Tinto reported net debt of US$14.1 billion at the half-year.

The company has also been progressing a capital-release programme targeting US5–10billion,withmorethanUS2 billion completed so far this year.

Glencore

Glencore reported net debt of US$10.2 billion as of 30 June 2026, lower than in the previous period.

The company has returned substantial capital to shareholders over the years, including additional payments announced alongside its half-year results.

Growth Pipelines and Key Risks

Copper: A Common Growth Priority

All three mining companies are focusing on copper as demand for the metal and its role in their earnings grow.

• BHP: Continues to explore operational expansion opportunities and leaching technologies to increase copper production.

• Rio Tinto: Is working to scale up production at Oyu Tolgoi and advance the Simandou project.

• Glencore: Is progressing brownfield copper projects and has outlined a pathway to substantially increase production over the next decade.

Iron Ore: Exposure to Steel Demand

Iron ore remains a major source of volume and cash flow for BHP and Rio Tinto.

This makes both companies particularly sensitive to changes in steel demand and fluctuations in seaborne iron ore prices.

Glencore: Energy and Trading Risks

Glencore has a different risk profile because of its exposure to coal and its global trading business.

Its earnings can be more sensitive to energy market movements, freight costs and geopolitical developments.

Risks Shared by All Three Companies

Despite their different portfolios, the three mining giants face several common risks:

• Commodity-price volatility: Changes in copper, iron ore and other commodity prices can affect revenue and profitability.

• Operational disruptions: Production issues can delay output and increase costs.

• Regulatory and permitting delays: Project approvals and permitting timelines can affect expansion plans.

• Geopolitical developments: Trade tensions, policy changes and energy market shifts can influence operations and commodity demand.

What Australian Investors Are Watching

Glencore's ASX listing gives Australian investors direct access to a company with significant Australian operations and a history of returning capital to shareholders through dividends and share buybacks.

BHP and Rio Tinto remain major options for investors seeking exposure to iron ore alongside growing copper businesses.

Recent operational updates highlight the differences between the three companies. Rio Tinto's September-quarter results showed progress at Oyu Tolgoi and continued sales from its Pilbara operations, while BHP's full-year results demonstrated the growing contribution of copper to its earnings.

Glencore's next production report is due this month.

Ultimately, the three mining companies offer different combinations of bulk commodities, base metals and, in Glencore's case, a substantial trading business. Their future performance will depend on copper and iron ore prices, operational efficiency and how quickly new projects begin producing and generating cash flow.
