Exxon Mobil said on Monday that it left Russia completely after President Vladimir Putin expropriated its properties following seven months of discussions over an orderly transfer of its 30% stake in a major oil project.

Exxon did not say if it received any compensation for the assets, which it had valued at more than $4 billion. An Exxon spokesperson declined to comment on whether it will proceed to contest the seizure through an international arbitration process, a possibility flagged in August.

Its departure illustrates the clash between the West and Russia over energy following Moscow's invasion of Ukraine in late February and threats of using nuclear weapons against the country and its supporters. BP, TotalEnergies, Equinor and Shell have all transferred properties to Russian partners or left operations behind.
