Cimarex Agrees to Sell Ward County Assets for $570 million

DENVER, May 24, 2018

"The sale of the Ward County assets is part of our continuous portfolio optimization and high-grading of our investment opportunities," said Tom Jorden, Cimarex Chairman, President and CEO. "Cimarex was among the first horizontal operators in the Bone Spring formation in Ward County and it's been a great area for us over the years.  However, the remaining Wolfcamp opportunities have not competed for capital versus other Cimarex projects."

The transaction is expected to close in the third quarter of 2018, subject to customary closing conditions and adjustments.

Scotiabank served as financial advisor to Cimarex on this transaction.
