EnCap Investments, a growth capital provider, and Double Eagle, an energy company, agreed to form two joint ventures, Double Eagle Energy Holdings IV and Tumbleweed Royalty IV. Financial terms were not disclosed. “We are excited about this new partnership with EnCap and are thrilled to do business with a group of people who have been longtime personal friends. Pairing EnCap with our longtime investors, Apollo and Magnetar, along with several large strategic institutions and our own personal capital, provides us with a unique strategic advantage. Together with the financial strength of our partnership, our track record of success, and our world-class operating team, we can confidently and aggressively pursue very large acquisitions while continuing to organically assemble smaller opportunities and undertake an ambitious development program,” Cody Campbell and John Sellers, Double Eagle Co-CEOs.
