Zenith Energy Reports Tunisia's Failure to Pay Arbitration Costs

12:25 AM EST, 11/09/2026 (MT Newswires) -- Zenith Energy (ZEN.L, ZENA.OL) reported that Tunisia repeatedly failed to pay its share of costs in a $573 million international arbitration brought by the company's UK subsidiaries under the 1989 UK-Tunisia bilateral investment treaty. The energy company said Monday that the International Centre for Settlement of Investment Disputes requested payment from Tunisia, as procedural expenses are normally shared equally between the parties. Zenith noted that the claimants continue to shoulder the costs and Tunisia's non-payment is impeding proceedings toward a final award.
