This document is a corporate news release issued by Berkeley Energia Limited on February 6, 2026, announcing a significant procedural milestone in its ongoing investment treaty arbitration against the Kingdom of Spain before the International Centre for Settlement of Investment Disputes (ICSID).

The release confirms that the claimant’s wholly owned subsidiary, Berkeley Exploration Limited, has formally filed its Memorial of Claim. The dispute arises under the Energy Charter Treaty (ECT) and concerns Spain's actions regarding the claimant's Spanish subsidiary, Berkeley Minera España SA, and the Salamanca Project. In its Memorial, the claimant seeks compensation in the quantum of approximately US$1.25 billion.

The filing encompasses the factual background of the dispute, the legal basis for the claims under the ECT, witness statements, and independent expert reports addressing technical, regulatory, and quantum assessments. Procedurally, the release notes that Spain is scheduled to submit its Counter-Memorial by July 2026, or alternatively, a Memorial on Jurisdiction by October 2026, should the ICSID tribunal elect to bifurcate the proceedings to determine jurisdictional objections prior to the merits of liability and damages.
