Joseph C. Winkler III
Mr. Winkler joined the board of directors of the general partner of Hi-Crush Partners LP in connection with its IPO and has continued to serve as a member of the Board of Directors of Hi-Crush Inc., serving as the Chairman of the Audit Committee. Mr. Winkler served as Chairman and Chief Executive Officer of NYSE-listed Complete Production Services, Inc. (“Complete”), a provider of specialized oil and gas services and equipment in North America, from March 2007 until February 2012, at which time Complete was acquired by Superior Energy Services, Inc. From June 2005 to March 2007, Mr. Winkler served as Complete’s President and Chief Executive Officer. Prior to that, from March 2005 until June 2005, Mr. Winkler served as the Executive Vice President and Chief Operating Officer of National Oilwell Varco, Inc., an oilfield capital equipment and services company, and from May 2003 until March 2005 as the President and Chief Operating Officer of the company’s predecessor, Varco International, Inc. (“Varco”). From April 1996 until May 2003, Mr. Winkler served in various other capacities with Varco and its predecessor, including Executive Vice President and Chief Financial Officer. From 1993 to April 1996, Mr. Winkler served as the Chief Financial Officer of D.O.S., Ltd., a privately held provider of solids control equipment and services and coil tubing equipment to the oil and gas industry, which was acquired by Varco in April 1996. Prior to joining D.O.S., Ltd., Mr. Winkler served as Chief Financial Officer of Baker Hughes INTEQ, and served in a similar role for various companies owned by Baker Hughes Incorporated including Eastman/Telco and Milpark Drilling Fluids. Mr. Winkler served as a member of the board of directors of Dresser-Rand Group, Inc., a NYSE-listed provider of rating equipment solutions, until its acquisition by Siemens in July 2015. Mr. Winkler is also a member of the board of directors of Commercial Metals Company, a vertically integrated Fortune 500 steel company, and serves on its Finance Committee and Compensation Committee, and a member of the board of directors of Eclipse Resources Corporation, an independent exploration and production company, and serves on its audit and compensation committees. Mr. Winkler recently joined the board of directors of Tetra Technologies Inc. and is a member of its audit committee. Mr. Winkler received a BS degree in Accounting from Louisiana State University. We believe that Mr. Winkler’s many years of operational, financial, international and capital markets experience, a significant portion of which was with publicly traded companies in the oil and gas services, manufacturing and exploration and production industries, make him particularly well-suited to serve on the board of directors of Hi-Crush Inc.
