The ownership of major oil refining and fuel retail assets in Southeast Europe has become more uncertain after US investment group Carlyle withdrew from active efforts to acquire Lukoil’s international operations. Rival investors are now competing for a transaction that remains dependent on US sanctions approval. The sale concerns refining and downstream fuel distribution assets across the region.
Refining and retail assets in Bulgaria and Romania
The proposed transaction covers refining facilities in Bulgaria and Romania, alongside a fuel retail network across seven southeastern European markets. Among the principal assets are Lukoil Neftochim Burgas, described as Bulgaria’s major refinery, and Romania’s Petrotel refinery. The wider international portfolio includes more than 800 petrol stations.
The petrol station network spans Bulgaria, Romania, Serbia, Croatia, Montenegro, Moldova and North Macedonia. The deal structure links refining capacity with distribution through the retail footprint across multiple national markets. This combination is intended to cover both upstream refining operations and downstream fuel supply channels.
Carlyle agreement blocked by US sanctions authorization
Carlyle had reached an agreement in January 2026 to acquire most of Lukoil’s foreign operations. However, the proposed transaction did not receive required authorization from the US Treasury Department’s Office of Foreign Assets Control. Carlyle’s withdrawal has left the sale process open to other potential investors.
One proposal associated with US billionaire Todd Boehly has attracted interest from Gulf-based investors, along with support from US officials, according to reporting. Lukoil has also indicated that discussions with other interested parties are continuing.
Negotiations allowed under general license until October 2026
The sale follows US sanctions imposed on Lukoil in connection with Russia’s war in Ukraine. Those restrictions have complicated transactions involving the company’s foreign assets, adding regulatory and geopolitical uncertainty.
US authorities have continued to permit negotiations under a general license extending until 22 October 2026. The ability to negotiate does not amount to approval for a completed sale. Investors therefore remain dependent on sanctions-related clearance before ownership changes can be finalized.
Impact on regional refining competition and fuel distribution
In Southeast European energy markets, the ownership question extends beyond purchase price considerations. Refineries and distribution networks hold positions within national fuel supply systems, while prospective buyers would take on operational, regulatory and capital investment responsibilities. A change in ownership could affect investment priorities and procurement arrangements.
The outcome may also influence regional fuel competition and downstream petroleum infrastructure investment decisions. However, investors must first resolve the sanctions-related approval requirements tied to any transfer of control.
