Rio Tinto Bolsters Green Metal Portfolio with Brazilian Aluminum acquisition

London, United Kingdom – January 31, 2026 – Mining giant Rio Tinto has announced a important investment in Brazil’s aluminum industry, solidifying its commitment to sustainable raw materials and a lower-carbon future. The Company confirmed Friday its entry into Companhia Brasileira de Alumínio (CBA), a leading Brazilian aluminum producer, thru a joint venture with the Aluminum Corporation of China (Chalco).

Deal Details and Financial Implications

The strategic partnership sees Chalco holding a 67 percent stake in CBA, while Rio Tinto will control the remaining 33 percent. The total transaction is valued at approximately $902.6 million, with Rio Tinto’s direct investment totaling around $297.8 million. This represents a premium of approximately 21 percent over CBA’s average share price over the preceding 20 days.

Key Transaction Details	Value
Takeover Target	Companhia Brasileira de Alumínio (CBA)
Total Transaction Volume	$902.6 million (approx.)
Rio Tinto Share	33% ($297.8 million approx.)
partner	aluminum Corporation of China (Chalco) – 67%
Key Asset	1.6 GW of Renewable Energy Capacity

Focus on Renewable Energy Capacity

A crucial element of this acquisition is CBA’s ample renewable energy capacity. The company boasts 1.6 gigawatts of power generated from hydroelectric and wind sources. This access to green energy is pivotal in producing “green aluminum,” increasingly sought after by industries aiming to reduce their carbon footprints. According to a recent report by the International Aluminium Institute, demand for low-carbon aluminum is projected to grow by 40% over the next five years.

Navigating Competitive Pressures

While the deal positions Rio Tinto for success in the burgeoning green metals market, the company faces growing competition. Shares of Rio Tinto were trading at GBX 6,719 on the London stock Exchange Friday amid a volatile commodities landscape. Brazilian competitor Vale recently announced a 2025 iron ore production of 336.1 million tonnes, surpassing Rio Tinto’s output from Australia’s Pilbara region – a frist since 2018. This shift underscores the intensifying competition within the iron ore sector, driving Rio Tinto to diversify its portfolio.

Strategic Diversification and Long-Term Positioning

This acquisition represents a deliberate move by Rio Tinto to move beyond purely volume-based business models. The focus on high-quality, sustainably produced assets is intended to secure the group’s long-term viability in a rapidly evolving market. This strategy is particularly relevant considering the increasing emphasis on Environmental, Social, and Governance

Rio Tinto’s Strategic Investment in CBA: Powering a Greener Future for Brazil

Rio Tinto’s recent acquisition of a 33% stake in Companhia Brasileira de Alumínio (CBA), a leading Brazilian aluminum producer, marks a critically important move towards bolstering its renewable energy portfolio and solidifying its commitment to enduring operations. The deal grants Rio Tinto access to 1.6 gigawatts (GW) of green power, primarily hydroelectric, positioning the company to significantly reduce its carbon footprint and enhance its competitiveness in the global aluminum market.

Understanding the CBA Partnership

CBA, headquartered in São Paulo, operates a fully integrated aluminum chain, from bauxite mining to primary aluminum production. This vertical integration is a key factor in Rio Tinto’s decision, offering a secure and reliable supply of aluminum alongside ample renewable energy capacity.

* Strategic Alignment: The partnership aligns with Rio Tinto’s broader decarbonization strategy, aiming for net-zero emissions by 2050. Access to low-carbon aluminum production is increasingly crucial as demand for sustainable materials rises.

* investment Details: While the exact financial terms haven’t been fully disclosed, the 33% stake represents a substantial investment, reflecting the value of CBA’s integrated operations and renewable energy assets.

* Joint operation: The agreement involves a collaborative approach, with Rio Tinto gaining portrayal on CBA’s board and participating in strategic decision-making.

The 1.6 GW of Green Power: A Deep Dive

The 1.6 GW of renewable energy capacity is predominantly sourced from hydroelectric power plants located in Brazil. This is a critical component of the deal, offering several advantages:

1. Hydroelectric Dominance: Brazil is a global leader in hydroelectric power generation, providing a stable and cost-effective source of renewable energy.
2. Reduced Carbon Intensity: Utilizing hydroelectric power significantly lowers the carbon intensity of CBA’s aluminum production, making it more attractive to environmentally conscious customers.
3. power Purchase Agreements (PPAs): Rio Tinto will likely leverage long-term PPAs with CBA to secure a consistent supply of renewable energy at predictable prices.
4. Potential for Expansion: The partnership opens doors for future investments in additional renewable energy projects, possibly including solar and wind power, to further expand CBA’s green energy capacity.

Impact on Rio Tinto’s Aluminum Business

This investment directly impacts Rio tinto’s aluminum operations in several key areas:

* Lower Production Costs: Access to cheaper, renewable energy will reduce CBA’s production costs, enhancing its competitiveness in the global aluminum market.

* sustainable Aluminum Supply: the deal provides Rio Tinto with a significant source of low-carbon aluminum, catering to the growing demand for sustainable materials from industries like automotive, packaging, and construction.

* Supply Chain Resilience: Securing a stake in CBA strengthens Rio Tinto’s aluminum supply chain, reducing reliance on external suppliers and mitigating potential disruptions.

* Meeting ESG Goals: The investment demonstrates Rio Tinto’s commitment to Environmental, Social, and Governance (ESG) principles, attracting investors and customers who prioritize sustainability.

Brazil’s Role in the Global Aluminum Landscape

Brazil is emerging as a key player in the global aluminum industry, driven by its abundant natural resources, competitive energy costs, and growing focus on sustainability.

* Bauxite reserves: Brazil possesses significant bauxite reserves, the primary raw material for aluminum production.

* Hydroelectric Potential: The country’s extensive hydroelectric infrastructure provides a reliable and affordable source of renewable energy.

* Government Support: The Brazilian government is actively promoting the progress of the aluminum industry through incentives and infrastructure investments.

* Growing Domestic Demand: Increasing domestic demand for aluminum,driven by economic growth and infrastructure development,is further fueling the industry’s expansion.

Case Study: Hydro Aluminum and Low-Carbon aluminum

The move by Rio Tinto mirrors strategies adopted by other aluminum producers, such as Hydro Aluminum. Hydro has been a pioneer in developing low-carbon aluminum products, utilizing renewable energy and innovative production processes. Their success demonstrates the growing market demand for sustainable aluminum and the potential for premium pricing. Rio Tinto’s investment in CBA positions it to compete effectively in this evolving market.

Future Outlook: Expanding Green Aluminum Production

The partnership between Rio Tinto and CBA is expected to drive further investment in green aluminum production in Brazil. This includes:

* Modernizing Existing Facilities: Upgrading CBA’s existing aluminum production facilities to improve energy efficiency and reduce emissions.

* Developing New Renewable Energy Projects: Investing in new solar, wind, and biomass projects to further expand CBA’s renewable energy capacity.

* Exploring Carbon Capture Technologies: Investigating the potential for implementing carbon capture and storage (CCS) technologies to further reduce emissions from aluminum production.

* Promoting circular Economy Principles: Implementing circular economy principles, such as aluminum recycling, to minimize waste and reduce the environmental impact of aluminum production.
