Vinson & Elkins counsel Kathryn Wilson of Houston helped the Canada Pension Plan Investment Board (CPPIB) negotiate an agreement to buy $300 million of common stock in the fast-growing Houston energy company Halcon Resources Corp.

That stock purchase deal is largely done, except for closing, but it’s contingent on Halcon completing a pending $1.45 billion acquisition of oil and gas assets in the Williston Basin, located primarily in North Dakota. On Oct. 22, Halcon announced a definitive agreement to buy the assets from Petro-Hunt of Dallas and an affiliated entity. The $1.45 billion consists of $700 million in cash and $750 million in equity.
