Why the Rio Tinto-Glencore Merger Collapsed: Lessons from Gary Nagle, Ivan Glasenberg, and What Glencore Might Do Next

April 27, 2026, Author - Ben McGregor

In February 2026, Rio Tinto and Glencore abandoned advanced merger talks that would have created the world's largest mining company. Disagreements over valuation, governance, and Glencore's coal assets proved insurmountable. Drawing on recent videos featuring Gary Nagle and Ivan Glasenberg, here's what really happened, why the deal failed, and how Glencore may pivot in a world reshaped by the Iran war and surging copper demand.

Introduction: A Merger That Almost Created the World’s Largest Miner

In early 2026, the mining world was buzzing with rumours of a transformative merger between Rio Tinto and Glencore. The potential combination would have created the largest mining company on Earth, surpassing BHP in scale and copper exposure. After months of preliminary discussions, the talks collapsed in February 2026. Rio Tinto stated it could not reach an agreement that would deliver value to its shareholders. Glencore countered that the proposed terms significantly undervalued its copper business and growth pipeline. Valuation, governance (leadership roles), and the handling of Glencore’s substantial coal assets were the main sticking points. This article draws on recent videos featuring Glencore CEO Gary Nagle and a third featuring former CEO Ivan Glasenberg to provide context on the company’s strategic thinking. It also examines how the global landscape — particularly the ongoing Iran war and energy market disruptions — may influence Glencore’s next moves.

 

Glencore’s Mindset

In this older but foundational video, Gary Nagle introduces himself as the new CEO succeeding Ivan Glasenberg. He emphasizes Glencore’s unique entrepreneurial culture, vertical integration (mining + marketing), and long-term thinking.

 

Key quote from Gary Nagle:

“We are not traders who happen to own mines. We are miners and traders who understand the physical market better than anyone else.”

Nagle stresses the importance of controlling the supply chain from mine to market, giving Glencore an information edge and the ability to create value through cycles.

 

(Gary Nagle Fireside Chat, July 2023)

Nagle discusses Glencore’s strategy, the Teck bid, coal rundown, and energy transition challenges. He highlights the massive copper deficit looming and the difficulty of bringing new supply online.

 

Key quotes from Gary Nagle:

“The metal doesn’t exist and the challenge that we have as a mining industry is to be able to bring these metals into the world to be able to develop projects, grow projects, and be able to feed the demand as it comes.” “We will not stay stagnant. This is a dynamic company. We are at the forefront of delivering the materials required for a decarbonization of the world.”

He also addresses the Teck coal bid, noting Glencore’s willingness to pursue both a full merger and a standalone coal acquisition.

 

Video 3 (Sky News Report on Early Merger Talks)

This news segment reports on the early-stage Rio Tinto–Glencore talks in early 2026, noting Rio’s desire for more copper and lithium assets and the potential inclusion of Glencore’s coal business in any deal structure.

 

Video 4 (Abandonment Announcement Coverage)

The final video covers the collapse of talks in February 2026, with both companies citing valuation disagreements. Rio Tinto emphasized shareholder value, while Glencore felt its copper growth pipeline was undervalued.

 

Why the Merger Fell Through: Valuation, Governance, and Coal

The primary reasons for the collapse were:

  • Valuation Disagreement: Glencore demanded approximately 40% ownership in the combined entity, which Rio Tinto viewed as too high given the relative contributions.

  • Governance Issues: Leadership roles (chair and CEO) were contentious. Rio Tinto wanted to retain control of key positions.

  • Coal Assets: Glencore’s large metallurgical and thermal coal portfolio was a sticking point. Rio Tinto had already exited coal and was focused on future-facing commodities like copper and lithium. Including coal complicated the deal’s narrative and ESG profile.

Gary Nagle had previously described a potential Rio Tinto combination as “the most obvious deal in mining,” highlighting synergies in copper and marketing. However, the final terms failed to bridge the gap.

 

How the World Has Changed Since Earlier Talks

The global context has shifted dramatically since Glencore’s earlier merger attempts:

  • The ongoing Iran conflict and Strait of Hormuz disruptions have created a persistent energy crisis, driving oil and LNG prices higher and reinforcing the need for secure supply chains.

  • Copper demand is surging due to AI data centers, electrification, and renewable energy infrastructure.

  • Western governments are accelerating “friend-shoring” of critical minerals, making stable jurisdictions like Canada, Australia, and Chile more attractive.

  • Resource nationalism is rising in some producing countries, increasing the value of assets in rule-of-law jurisdictions.

These changes likely make Glencore more focused on copper and energy-transition metals while viewing coal as a cash-generating asset to fund growth elsewhere. Ivan Glasenberg’s earlier emphasis on vertical integration and cycle management remains relevant, but the energy shock may push Glencore toward even greater emphasis on copper and nickel.

 

What Glencore Might Do Next: Speculation Based on Strategy and Current Realities

Based on Gary Nagle’s and Ivan Glasenberg’s public statements and Glencore’s recent actions, several potential next steps emerge:

  1. Copper-Focused Acquisitions: Glencore is likely to pursue more copper assets in stable jurisdictions (Canada, Australia, Chile) to capitalize on the structural supply deficit.

  2. Portfolio Optimization: Further divestitures of non-core or high-carbon assets to sharpen focus on copper, nickel, and critical minerals.

  3. Joint Ventures and Partnerships: As seen with the Vale JV in Sudbury, Glencore may prefer partnerships that share risk and leverage existing infrastructure.

  4. Organic Growth + Brownfield Expansions: Low-capital-intensity brownfield projects (e.g., expansions around existing operations) remain attractive.

  5. Coal Cash Flow Utilization: The recently acquired Elk Valley coal business generates strong cash flow that can fund copper and critical minerals growth.

Glencore’s philosophy — control the supply chain, think in decades, and act decisively during cycles — suggests it will remain opportunistic but disciplined.

 

Implications for Canadian Mining Investors

 

Glencore’s activity in Canada (Teck coal acquisition, Sudbury JV, etc.) demonstrates its confidence in Canadian assets. For TSX/TSXV investors:

  • Quality copper and critical minerals projects in stable provinces (Ontario, Quebec, Saskatchewan) may attract Glencore interest.

  • Junior miners with advanced, de-risked assets could become acquisition or partnership targets.

  • The broader trend of majors preferring acquisitions over exploration benefits Canadian juniors with high-grade discoveries.

 

Risks and Balanced Perspective

M&A is never guaranteed. Valuation gaps, regulatory hurdles, and integration challenges can derail deals. However, Glencore’s track record suggests that when it shows serious interest, value creation often follows.

 

Conclusion: Glencore’s Moves Remain a Powerful Signal

Dave Lotan’s advice — “when the guys from Glencore show up, you need to pay attention” — is as relevant as ever. The failed Rio Tinto merger, combined with Glencore’s recent Canadian activity and Gary Nagle’s strategic comments, shows a company laser-focused on copper, energy transition metals, and long-term value creation amid geopolitical and energy market volatility. For Canadian mining investors, tracking Glencore’s filings, partnerships, and geographic focus offers a practical way to identify high-potential opportunities. In a world where exploration is becoming more expensive and risky, Glencore’s preference for proven assets in stable jurisdictions like Canada creates clear opportunities for quality juniors and mid-tier companies.
