Gastar Exploration Inc. (NYSE MKT: GST) (“Gastar” or the “Company”) is pleased to announce that Mr. Jerry R. Schuyler, a current independent director of Gastar, has been appointed Chairman of Gastar’s Board of Directors, replacing Mr. John M. Selser, Sr. who has resigned from Gastar’s board of directors to devote more time to other business interests.

Mr. Schuyler joined Gastar as a director in August 2014 and also serves as a member of Gastar’s Compensation and Reserves Review Committees. Mr. Schuyler previously served as a director and as Chief Operating Officer of Laredo Petroleum, Inc. (“Laredo”) where he was promoted to President, serving in those capacities until July 2013 when he announced his retirement. During Mr. Schuyler’s tenure at Laredo, he was instrumental in helping the company grow from a private equity-financed start-up company into a publicly traded company listed on the NYSE. Mr. Schuyler also previously served as a director for Rosetta Resources Inc. until its acquisition by Noble Energy. Inc. earlier this year. Mr. Schuyler has a Bachelor of Science degree in Petroleum Engineering from Montana College of Mineral Science and Technology and attended several graduate business courses in the executive program at the Bauer College of Business at the University of Houston.

“Jerry Schuyler brings his broad technical background and proven boardroom leadership experience to the role of Chairman of Gastar’s Board of Directors,” said J. Russell Porter, Gastar’s President and CEO.  “The Board joins me in thanking John Selser for his service and we wish him well as he focuses on his private endeavors.”

Gastar’s Nominating and Governance Committee will commence a search for a new independent director candidate to fill the vacancy left by Mr. Selser’s resignation. Mr. Selser advised the Company that his resignation was not because of any disagreement with the Company on any matter related to or with Gastar over the Company’s operations, policies or practices.
