Procedural Posture

This document is a regulatory announcement issued by Ascent Resources Plc on 8 July 2026, confirming the issuance of the final award in ICSID Case No. ARB/22/21. The underlying arbitration was brought by Ascent Resources Plc and Ascent Slovenia Ltd against the Republic of Slovenia under the Energy Charter Treaty (ECT). The dispute concerned regulatory measures affecting the Petišovci gas field in Slovenia, notably including the 2022 amendments to the Slovenian Mining Act.

Tribunal's Analysis and Findings

The announcement outlines the core dispositive findings of the unanimous final award dated 7 July 2026. The Tribunal dismissed all of the Respondent's jurisdictional objections, affirming its competence to adjudicate the totality of the Claimants' claims under the ECT. However, on the merits of the dispute, the Tribunal rejected the Claimants' allegations of treaty breaches, specifically denying all claims advanced under Article 10 (Fair and Equitable Treatment) and Article 13 (Expropriation) of the ECT. Consequently, the Claimants' request for compensation was denied in its entirety.

Costs and Dispositif

In its allocation of costs, the Tribunal ordered the Claimants to pay EUR 3,000,000 in respect of the Respondent's legal representation and expenses. The costs of the arbitration proceedings were apportioned in equal shares between the parties. All other claims were formally dismissed, rendering the award final and binding upon the parties.
