Sale supports company’s disciplined investment strategy, Nigeria’s efforts to enhance industry participation

Includes shallow-water affiliate; ExxonMobil to retain deepwater assets

Transaction to close later this year pending regulatory approvals

IRVING, Texas – ExxonMobil has reached an agreement to sell its equity interest in Mobil Producing Nigeria Unlimited to Seplat Energy, a Nigerian independent oil and gas company, through its wholly-owned subsidiary Seplat Energy Offshore Limited.

“This sale will allow us to prioritize competitively advantaged investments in our strategic assets, and it supports the Nigerian government’s efforts to grow its oil and gas operations,” said Liam Mallon, president, ExxonMobil Upstream Oil and Gas. “We value the relationships we have spent decades building with the government and people of Nigeria, which will continue as we maximize the value from our deepwater operations.”

When finalized, the sale will include the Mobil Development Nigeria and Mobil Exploration Nigeria equity ownership of Mobil Producing Nigeria Unlimited, which holds a 40% stake in four oil mining licenses, including more than 90 shallow-water and onshore platforms and 300 producing wells.

ExxonMobil will maintain a significant deepwater presence in Nigeria, including interests in the Erha, Usan and Bonga developments via EssoExploration and Production Nigeria Limited and Esso Exploration and Production Nigeria (Deepwater) Limited.

The sale will not result in any loss of employment and is expected to close later this year subject to regulatory and other approvals.
