We are pleased to announce that in October 2025, the ad hoc Arbitration Tribunal based in Stockholm issued a ruling in the case of Orlen S.A. (formerly PGNiG S.A.) v. Gazprom PJSC and Gazprom export LLC (“Gazprom”) for payment of interest on overpayments for natural gas supplied under the Yamal Contract in 2014-2020. The Tribunal upheld Orlen’s claim in full, awarding Orlen USD 118 million from Gazprom, plus further interest and legal costs. The total financial benefit to Orlen is estimated at approximately USD 146 million.
The above case is part of a multifaceted dispute between Orlen and Gazprom concerning, among other things, changes in the contract price in 2017-2022 and the causes and consequences of the interruption of natural gas supplies in 2022. Previously, Rymarz Zdort Maruta represented Orlen in other proceedings concerning the Yamal Contract, including arbitration proceedings concluded in 2020 with a favourable ruling for our Client, as referred to in the following announcement: https://rzmlaw.com/en/pgnig-succeeds-in-arbitration-proceedings-against-gazprom-regarding-the-revision-of-the-price-for-gas-supplied-under-the-yamal-contract/.
