WPX Energy Inc. closed its offering of $900 million of 4.500% senior unsecured notes due 2030 at par, according to a Jan. 10 release.

The proceeds will be used to finance part of the cash consideration of the previously announced $2.5 billion acquisition of Delaware Basin-focused producer Felix Energy LLC and for related costs.

If the acquisition does not close, the notes will be subject to a special mandatory redemption.

Barclays Capital Inc. and Citigroup Global Markets Inc. acted as joint lead book-running managers for the notes offering.
