(Bloomberg) -- Exxon Mobil Corp. agreed to sell its 50% stake in a deepwater natural gas project in the Black Sea to Romania’s state-owned Romgaz SA for $1.06 billion.

The deal hinges on Romgaz SA obtaining approval from shareholders, according to a regulatory statement to the Bucharest Stock Exchange on Tuesday. 

Exxon will turn over operatorship of the Neptun Deep project to Bucharest-based OMV Petrom, which owns the other 50% stake once the transaction closes. The U.S. supermajor is exiting the development more than a decade after it began exploring the region adjacent to massive gas discoveries in Turkish-controlled waters. 

Exxon is prioritizing key projects in Guyana, the U.S. Permian Basin as well as oil-refining and chemical build-outs since a strategic reboot last year, when the company posted its first annual loss in four decades. The recent upswing in commodity prices provides an improved opportunity to sell assets, Chief Executive Officer Darren Woods said last week. 

Romgaz’s purchase of Neptun Deep may clear the way for the project to move forward even as an ongoing Romanian government crisis clouds the prospects for tax-law changes. OMV Petrom has repeatedly warned that 2021 is a crucial year for the project, signaling time is running out for Romanian authorities to deliver on promised tax modifications.
