Partnership with Gazprom Neft; Gazprom has a 50% stake in NIS. Serbia expects US sanctions against local Gazprom Neft structure Serbian NIS, where 56.15% is owned by Russian companies, may fall under US sanctions as early as January 1, 2025, said the country's President Aleksandar Vucic. In 2022, the company's main shareholder, Gazprom (MOEX: GAZP) Neft, reduced its stake to avoid restrictive measures, and so Gazprom appeared in NIS's capital. Now Belgrade is talking about the need for a new reduction in the package. The most likely contender for the stake is the Serbian authorities, analysts believe.
