Imerys' Lithium Pivot: A Commodity Balance Perspective

The lithium market is being pulled by a powerful, long-term force: the global shift to electric mobility and renewable energy. This transition is creating an unprecedented demand surge, with the UK government itself projecting that yearly demand for lithium will increase by 1,100% by 2035. That level of growth pressure is extreme, meaning the industry must scale production almost tenfold in under a decade to keep pace. This isn't just about incremental growth; it's a fundamental reconfiguration of the global energy system, with lithium as a key enabler.

To secure this supply, governments are stepping in. The UK's new Critical Minerals Strategy – Vision 2035 sets a clear target: to source 10% of domestic demand from UK production by 2035. This policy creates a supportive, long-term demand backdrop for domestic projects, aiming to diversify supply chains and reduce reliance on concentrated global sources. The strategy underscores the vulnerability of current supply chains, where a single country dominates refining and mining, leaving nations exposed to geopolitical and price shocks.

Yet, translating policy targets into actual mines is proving immensely difficult. The primary constraint is capital, not geological potential. A stark example illustrates the challenge: an innovative lithium mine project in Germany took eight times as long to secure debt financing as a comparable gas-fired power plant did during the pandemic. This delay isn't due to project quality but to the perceived risk and complexity of financing new, low-carbon infrastructure. The financial ecosystem is still learning how to fund these emerging business models, creating a bottleneck that can stall projects before they even break ground.

The bottom line is a market under immense structural pressure. Demand is projected to explode, policy is creating a supportive framework, but the path to building new supply is long and fraught with financial hurdles. This sets the stage for a market where securing financing and navigating project delays will be as critical as the commodity's physical availability.

Project Economics and Capital Efficiency

The scale and funding efficiency of Imerys' two lithium ventures tell a clear story of capital prioritization. The French Emili project is a major undertaking, targeting 34,000 tons a year of lithium hydroxide starting in 2030. That output is roughly equivalent to the UK project's stated goal of producing over 20,000 metric tons annually of lithium carbonate. In terms of physical scale, both are significant, but the French venture is the more advanced and larger of the two.

The key differentiator is funding clarity. The Emili project has secured a decisive early capital commitment: the French state, via Banque des Territoires, is investing €50 million for a minority stake. This isn't just a symbolic gesture; it's a strategic bet to support the project through its definitive feasibility study, a critical milestone expected in early 2027. This state backing provides a crucial layer of financial credibility and de-risks the next phase of development.

By contrast, the UK project's suspension signals a stark reality. After completing a scoping study, Imerys placed the project on care and maintenance, with no restart date given. This decision, made by CEO Alessandro Dazza, is a direct response to the capital-intensive nature of these ventures. As the evidence on financing bottlenecks shows, securing debt for new, low-carbon projects can be eight times as long as for more conventional infrastructure. In that context, the UK project's pause is a pragmatic choice to focus resources on the French venture, where a near-term funding pathway is already in place.

The strategic implication is clear. Imerys is prioritizing projects with clearer, more immediate capital efficiency. The Emili project's state-backed feasibility study represents a tangible step toward a final investment decision, while the suspended UK project remains in a state of financial uncertainty. This is a common dynamic in the lithium sector, where the ability to navigate complex financing is as critical as the commodity's physical potential.

Market Implications and Forward Balance

The shift in Imerys' focus has a direct, near-term impact on the lithium supply balance. The indefinite suspension of the UK project removes a potential source of new supply from the timeline. That project was designed to produce over 20,000 metric tons annually of lithium carbonate, a significant volume that could have helped ease the market's persistent deficit. By pausing it, Imerys is effectively maintaining the current tightness in the supply equation as demand continues to surge. This delay could support price stability or even modest strength in the near term, as the market has less new capacity coming online.

The primary catalyst for the next phase of supply growth now hinges on the French Emili project. The key milestone is the completion of its definitive feasibility study, expected in early 2027. That study is the final technical and financial hurdle before a final investment decision (FID). Once the FID is made, the project can move into construction, with production targeting 34,000 tons a year of lithium hydroxide from 2030. For the market, the early 2027 study completion is the next major signal, as it will either confirm the project's viability and unlock its capital commitment or reveal unforeseen hurdles.

In the meantime, investors should watch Imerys' own capital allocation for a clear signal of its priorities. The company's 2026 capital expenditure guidance will show how much funding is being redirected from the suspended UK project to support the French venture and other strategic initiatives. Given the project's scale and the state's €50 million investment to support its study, the capex guidance will reveal the group's commitment level. It will also indicate whether the capital efficiency focus seen in the project shift is translating into disciplined spending across the broader portfolio, a critical factor for a company navigating a capital-intensive transition.
