CVR Energy Inc. plans to buy Gary-Williams Energy Corp. and its Wynnewood, Okla., refinery and related assets for $525 million in a transaction expected to close by yearend.
Closing remains subject to regulatory approvals.
CVR Energy said acquisition of the 52,500-b/cd Wynnewood refinery will increase the scale and diversity of CVR Energy's refining operations.
Based in Sugar Land, Tex., CVR Energy already owns 120,000 b/cd refinery in Coffeyville, Kan.
Gary-Williams Energy is based in Denver with marketing and operations in Oklahoma.
