LONDON: Rio Tinto and Arcadium Lithium plc (NYSE: ALTM) announced a definitive agreement under which Rio Tinto will acquire Arcadium in an all-cash transaction for US$5.85 per share.

The transaction represents a premium of 90% to Arcadium’s closing price of $3.08 per share on 4 October 2024, a premium of 39% to Arcadium’s volume-weighted average price (VWAP) since Arcadium was created on 4 January 2024, and values Arcadium’s diluted share capital at approximately $6.7 billion.

The transaction will bring Arcadium’s world-class, complementary lithium business into Rio Tinto’s portfolio, establishing a global leader in energy transition commodities – from aluminium and copper to high-grade iron ore and lithium.

Arcadium Lithium is a global, fast-growing, vertically integrated lithium chemicals producer with an asset base of long-life, low-cost operations and growth projects.

It has leading capabilities in lithium chemicals manufacturing and extraction processes, including hard-rock mining, conventional brine extraction and direct lithium extraction.

Arcadium’s current annual lithium production capacity across a range of products including lithium hydroxide and lithium carbonate is 75,000 tonnes lithium carbonate equivalent, with expansion plans in place to more than double capacity by the end of 2028.

Arcadium’s global operations, comprising approximately 2,400 employees, include facilities and projects in Argentina, Australia, Canada, China, Japan, the United Kingdom and the United States.

Rio Tinto Chief Executive Officer Jakob Stausholm said: “Acquiring Arcadium Lithium is a significant step forward in Rio Tinto’s long-term strategy, creating a world-class lithium business alongside our leading aluminium and copper operations to supply materials needed for the energy transition.

Arcadium Lithium is an outstanding business today and we will bring our scale, development capabilities and financial strength to realise the full potential of its Tier 1 portfolio.

This is a counter-cyclical expansion aligned with our disciplined capital allocation framework, increasing our exposure to a high-growth, attractive market at the right point in the cycle.

“We look forward to building on Arcadium Lithium’s contributions to the countries and communities where it operates, drawing on the strong presence we already have in these regions. Our team has deep conviction in the long-term value that combining our offerings will deliver to all stakeholders.”

Arcadium Lithium CEO Paul Graves said: “We are confident that this is a compelling cash offer that reflects a full and fair long-term value for our business and de-risks our shareholders’ exposure to the execution of our development portfolio and market volatility.

Arcadium Lithium is a leading global lithium producer with the widest offering of lithium chemical products and a world-class manufacturing network, backed by a broad technology portfolio and expertise in all aspects of the lithium value chain.

This agreement with Rio Tinto demonstrates the value in what we have built over many years at Arcadium Lithium and its predecessor companies, and we are excited that this transaction will give us the opportunity to accelerate and expand our strategy, for the benefit of our customers, our employees, and the communities in which we operate.”
