Share Repurchase Authorization
The Company’s board of directors (the “Board”) has authorized an initial share repurchase program of up to $100 million of the Company’s outstanding shares of common stock. This program is intended to continue the Company’s commitment to shareholder returns, capital discipline, and the efficient management of the Company’s assets, including cash on hand. David Rottino, Riviera’s President and CEO remarked, “Since 2017, the Company’s predecessor, Linn Energy, Inc. has paid down all debt and returned almost $800 million to shareholders.  Given our strong cash position and our expectation of continuing cash flows from our mature assets and/or potential opportunistic monetizations, we remain committed to returning capital to shareholders in a meaningful way. We believe this authorization highlights that commitment.”

Blue Mountain Plant Expansion
Due to rapidly increasing throughput and heightened rig activity supported by consistently strong well results, the Board has approved Blue Mountain’s plan to initiate the engineering and design of a second plant servicing the highly prolific Merge/SCOOP/STACK play in central Oklahoma. Targeting a completion date in the second half of 2019, the second cryogenic processing plant would increase total processing capacity up to 500 mmcf/d.  Greg Harper, President and CEO of Blue Mountain, stated, “In June, we were pleased to bring our new state of the art processing facility on-line on time and on budget.  We are currently processing approximately 150 mmcf/d, more than our original forecast, and we expect that to continue to increase and reach its full capacity of 250 mmcf/d by mid next year based on the results we are seeing from our dedicated producers.  Based on these results and predictable growth in the basin, we intend to begin the engineering and design of a new plant and continue to be excited about our prospects.”

NW STACK Operated Drilling Rig
The Company also received Board approval to initiate an operated drilling program in the NW STACK play starting in the fourth quarter of 2018.  The Company is encouraged by recent results from offset operators, including wells the Company participated in as a non-operator. With over 60,000 net acres in the Company’s core NW STACK focus area, Riviera believes extensive upside could be realized by delineating the play with an operated rig.  David Rottino further commented, “We are encouraged by recent activity in and around our core NW STACK position.  The technical team has presented a plan to further delineate the play in a way that we believe will add significantly to the Company’s net asset value.  Furthermore, we believe Blue Mountain can provide a midstream solution to our upstream plans.  Combined, we believe the value creation opportunity for shareholders is extremely attractive.”
