Mr. Hess previously served as the president of Pratt & Whitney, a division of United Technologies Corp., from January 1, 2009 through his retirement on January 1, 2014. During this time he was responsible for Pratt & Whitney’s global operations in the design, manufacture, and service of aircraft engines, space propulsion systems, and industrial gas turbines. Mr. Hess joined Pratt & Whitney after serving as president of Hamilton Sundstrand, the United Technologies division where he began his professional career in 1979. Mr. Hess guided Hamilton Sundstrand from 2005 through 2008 and was instrumental in securing major systems contracts on the Boeing 787, the Airbus A380, the F-35 Joint Strike Fighter, the Mitsubishi Regional Jet, the Embraer regional jet family, and Sikorsky’s CH-53K helicopter. Before becoming president, Mr. Hess headed Hamilton Sundstrand’s Aerospace Power Systems business segment, overseeing the Air Management Systems, Power Systems, and Electric Systems divisions as well as HS Nauka of Russia and Nord-Micro of Germany. Other roles he filled while at Hamilton Sundstrand include vice president and general manager of the Air Management and Power Systems divisions, with oversight of the auxiliary power unit, environmental control system, and fan product lines; as vice president of the Environmental Control Systems division, responsible for all environmental control system product lines; and as general manager of Hamilton Standard Commercial Aircraft Electronics Inc. in Colorado Springs, Colorado. Mr. Hess earned a bachelor’s degree in physics from Hamilton College, in Clinton, New York, and both a bachelor’s and a master’s degree in electrical engineering from Rensselaer Polytechnic Institute, in Troy, New York. In 1989 Mr. Hess was awarded an MIT Sloan Fellowship, earning a master’s degree in management in 1990.

The Board has determined that Mr. Hess will be an independent director under applicable New York Stock Exchange listing requirements. As a non-employee director of the Board, he will be entitled to receive the same standard compensation amounts paid to other non-employee directors for service on the Board and the Compensation Committee, as detailed in the RTI International Metals, Inc. Board of Directors Compensation Program referenced as Exhibit 10.11 to the Annual Report on Form 10-K filed by the Company with the U.S. Securities and Exchange Commission on March 18, 2014 (with such referenced information incorporated herein by reference).
