The delay in selling the Russian-controlled stake in NIS is linked to a mix of geopolitical, regulatory, strategic and commercial factors involving Russia, Serbia, Hungary and the United States. The process is tied to how future control of Serbia’s energy asset will be structured.
Gazprom Neft and Gazprom hold approximately 56.2% of NIS, while the Serbian state owns 29.9%. After US sanctions targeting Russian energy interests, Washington demanded divestment of the Russian ownership stake. In January 2026, Hungarian energy group MOL Group signed an agreement to acquire the Russian shareholding.
Energy-security conditions raised by Belgrade
A key obstacle is Serbia’s stated focus on energy security. NIS operates Serbia’s only oil refinery in Pančevo, and it is described as central to fuel supply, storage, logistics and petroleum distribution.
Belgrade has said any new owner must guarantee continued refinery operation, domestic market supply and fulfillment of obligations previously undertaken by NIS. Serbian officials have also publicly expressed dissatisfaction with some elements of MOL’s proposals.
Bids, valuation questions and ownership structure
Deal completion has also been affected by valuation and control issues. Reports indicate that more than one potential buyer has shown interest beyond MOL.
A Serbian company led by businessman Ranko Mimović submitted a bid reportedly worth around €2 billion. The Serbian government rejected the proposal quickly, citing the bidder’s lack of industry experience, but the competing offer raised questions about valuation and ownership structure.
OFAC approvals and multi-party regulatory steps
The transaction requires approvals from multiple parties, including US authorities through the Office of Foreign Assets Control (OFAC). Other approvals are also needed from the Russian sellers, the Serbian government and additional regulatory bodies.
Because the sale is part of a sanctions-related divestment process, it is described as more complex than a standard M&A transaction.
Sanctions pressure and regional control implications
NIS is described as more than a refinery operator in the Western Balkans. Transfers of control are said to affect regional fuel supply chains, crude sourcing, logistics infrastructure and energy influence in Southeast Europe.
The positions attributed to each side include Russia seeking to exit under sanctions pressure while preserving value, Hungary seeking to strengthen its regional energy position, and Serbia seeking to retain influence over a company described as vital to national energy security.
Extended deadlines during final negotiations
The unresolved issues have contributed to multiple deadline extensions. US authorities granted additional time for negotiations beyond an original May deadline.
Talks were extended first past May and later allowed to continue into June. Both MOL and Serbian officials have acknowledged that negotiations reached a final but highly complex phase with key conditions still unresolved.
Governance questions for future NIS control
The dispute increasingly centers on what governance structure for NIS will look like after Russian ownership is reduced. The main questions cited include who will control refinery operations and how Serbia’s interests will be protected.
The discussions also cover whether the state will increase its stake and what long-term commitments a new majority owner would make regarding investment and fuel supply. From a business standpoint, these points are framed as central to determining how operations would be run after any ownership change.
NIS role in Serbian revenues and supply stability
NIS is described as contributing significantly to tax revenues, fuel security, industrial activity and energy stability in Serbia. As a result, negotiations are characterized as extending beyond corporate ownership into a broader state-level issue rather than a conventional share sale.
