Eramet in Turmoil as CFO Suspension Follows CEO's Abrupt Exit

PARIS, FRANCE – February 09, 2026 – French mining giant Eramet SA plunged deeper into a leadership crisis today with the confirmation that its Chief Financial Officer has been temporarily suspended, just over a week after the board abruptly dismissed its Chief Executive Officer. The dual executive departures have sent shockwaves through the market, erasing over 17% of the company's value in a week and raising urgent questions about corporate governance and stability at a key supplier of minerals for the global energy transition.

A Crisis of Confidence

In a statement released this morning, Eramet confirmed that a temporary management structure was in place for its finance department following the suspension of CFO Abel Martins-Alexandre. The company took pains to state the move was "unrelated to the departure of Paulo Castellari as CEO" and was initiated "purely to allow for the proper conduct of the independent investigation."

That investigation, the company revealed, was triggered by "a warning from several employees of the finance department concerning the management of said department." This development is particularly stunning given Martins-Alexandre's brief tenure; the highly-regarded finance veteran, with a long career at Rio Tinto, only joined Eramet on September 15, 2025, lasting less than five months in the role.

The news sent Eramet’s shares tumbling another 6% in afternoon trading, making it the biggest loser on the SBF 120 index. This follows an 11.5% plunge just a week ago after the ousting of the CEO, compounding investor anxiety ahead of the group’s annual results, which Eramet insists are still scheduled for February 18th.

A Tale of Two Departures

The suspension of the CFO comes on the heels of another dramatic exit from the C-suite. On February 1st, the Board of Directors terminated the mandate of CEO Paulo Castellari, citing "divergences on operating methods." Chairwoman Christel Bories, whom Castellari had succeeded in May 2025, was immediately re-appointed as interim CEO, a move that concentrates power back in her hands.

While Eramet's official statements attempt to build a firewall between the two events, the proximity and severity of the shake-up have fueled speculation about deeper issues. Reports indicate that Castellari and Martins-Alexandre, who were seen as allies, had recently begun assembling an internal task force to investigate potential financial mismanagement within the group from prior years. The "divergences" that led to Castellari's dismissal are believed to relate to clashes with the board over operational strategy, cost-cutting measures, and capital allocation priorities.

These tensions may be exacerbated by the company's shareholder structure, which includes the founding Duval family and the French state. Historical disagreements between these major stakeholders over strategic direction—whether to prioritize shareholder payouts or long-term growth investments—are known to simmer beneath the surface, potentially complicating leadership decisions and the current search for a permanent CEO.

Governance and Whistleblowers Under the Spotlight

The revelation that finance department employees triggered the investigation into their own CFO casts a harsh light on Eramet's internal culture and control mechanisms. It highlights the growing power of internal whistleblowers in France, a framework significantly strengthened by the 2016 Sapin II law and the 2022 transposition of the EU Whistleblowing Directive.

While Eramet has an established "EthicLine whistleblower system" and a dedicated Ethics & Compliance Department, the fact that employees felt the need to raise a formal warning about the management of a key department suggests significant internal friction. The company's Audit, Risks & Ethics Committee will now be under intense pressure to ensure the independence and thoroughness of the investigation.

For investors and analysts, the situation raises red flags. Some market watchers question whether the two events, while officially separate, could point to systematic cultural problems or inadequate executive vetting processes. By attempting to present the issues as isolated incidents, the company may have inadvertently signaled a more pervasive governance challenge to the market.

Market Jitters and Strategic Uncertainty

The market's reaction has been swift and brutal. The leadership vacuum has created what some have termed a "perfect storm of confidence erosion." Maxime Kogge of Oddo BHF noted that the situation "couldn't come at a worse time," warning of a potential credit rating downgrade due to the company's strained finances. Reflecting this sentiment, Kepler Cheuvreux downgraded its rating for Eramet to "Sell" on February 2nd.

With a market capitalization that has shrunk to around €1.93 billion, the turmoil strikes at a critical moment. Eramet is a pivotal player in the supply chain for materials like lithium, nickel, and cobalt—metals essential for batteries and the broader energy transition. The current instability threatens to distract management and derail necessary operational improvements in its capital-intensive mining operations.

All eyes are now on February 18th, the scheduled date for the release of Eramet's annual results. Investors and partners, who would normally look to the executive team for guidance and a clear strategic vision, will instead be met by an interim CEO and a finance department under temporary leadership, all overshadowed by an ongoing internal investigation. The leadership crisis has created a void at the top, leaving fundamental questions about Eramet's financial health, operational continuity, and strategic direction hanging in the balance.
