Naftogaz, a Ukrainian gas transport company, has won a $1.4 billion case against Gazprom.

Naftogaz, the Ukrainian state-owned energy company, announced on Friday that it had won a legal case against Gazprom in Russia over the payment for a debt of $1.4 billion for gas transport.

The Swiss Federal Supreme Court rejected a request from Gazprom seeking to reverse an arbitral award made in June 2025 that ordered it to pay more than $1.4billion to?Naftogaz, along with interest.

Naftogaz said that the court ordered Gazprom also to pay court costs of 200,000 Swiss Francs ($254,000), and compensate Naftogaz for the proceedings in the amount of 250,000 Swiss Francs.

Gazprom didn't immediately respond to a comment request.

The Swiss court has found this week that the complaint of a Russian company majority owned by the government was unfounded.

Naftogaz reported that in June 2025 a Swiss arbitral court ordered Gazprom pay the debt for services of gas transportation,?alongside interest and arbitration fees, Naftogaz stated.

Serhiy koretskyi, Naftogaz's CEO, was quoted as saying that "Switzerland’s highest court has?confirmed?the validity of the arbitral decision and rejected definitively the Russian side's argument."

Koretskyi said that Naftogaz would continue to work towards the enforcement of the award.

The Ukrainian company filed arbitration proceedings against Gazprom 2022. They demanded that the Russian oil giant?pay for services rendered in organising natural gas transport through Ukraine.
