Earthstone Energy, Inc. Announces Increase in Borrowing Base

Borrowing Base Increases 32%; Liquidity Exceeds $250 Million

THE WOODLANDS, Texas--()--Earthstone Energy, Inc. (NYSE: ESTE) (“Earthstone” or the “Company”), today announced that it has entered into an amendment to its senior secured revolving credit facility (“Credit Facility”) under which the borrowing base has been increased from $360 million to $475 million in connection with its regularly scheduled redetermination. Further, the amendment provides for an increase in the borrowing base from $475 million to $550 million upon closing of the Company’s previously announced acquisition of privately held assets located in the Midland Basin from Tracker Resource Development III, LLC and an affiliate and from affiliates of Sequel Energy Group LLC (collectively, the “Tracker Acquisition”).

As of March 31, 2021, we had $1.4 million in cash and $223.4 million of long-term debt outstanding under our Credit Facility. Adjusted for the increase in the borrowing base to $475 million, we had $251.6 million of undrawn borrowing base capacity and $1.4 million in cash, resulting in total liquidity of approximately $253.0 million. We continue to expect closing of the Tracker Acquisition to occur early in the third quarter of 2021. Based on the $81.6 million cash consideration to be paid in the Tracker Acquisition and anticipated interim period cash flows that will reduce the cash requirement at closing, we expect a slight increase in liquidity at closing of the acquisition given the concurrent $75 million increase in the borrowing base.

Robert J. Anderson, Earthstone’s President and CEO, commented, “The continued support of our lending group is reflective of our track record, strategy and financial discipline and we appreciate their participation. The support of our lenders along with our continued operational focus and acquisition activity emphasizing low-cost, high-margin producing assets has increased Earthstone’s scale and liquidity. Our strategy of consolidating assets to increase scale and efficiency remains intact with further optionality given our increased liquidity.”
