Pittsburgh, PA, September 19, 2013 – Allegheny Technologies Incorporated (NYSE:ATI) announced today that John D. Sims has been named Executive Vice President, High Performance Forgings and Castings, Primary Titanium Operations, and Engineered Alloys. Mr. Sims has also been named President of our ATI Ladish business unit. Mr. Sims continues to report to Rich Harshman, ATI’s Chairman, President and Chief Executive Officer. Gary J. Vroman, previously responsible for ATI Ladish, announced his plans to retire effective December 31, 2013. Until his retirement, Mr. Vroman will be a Special Advisor reporting to Mr. Harshman.

“John Sims is well-qualified to take on the additional responsibility for ATI’s high performance forgings and castings business,” said Rich Harshman. “John brings a deep knowledge of and experience in our high performance titanium alloys, nickel-based alloys and superalloys operations. This experience and knowledge base is combined with John’s strong technical background and his established track record of strategy development and execution. John will bring a strong focus on lean manufacturing and operational excellence as we accelerate the pace of progress to enhance the technology leadership and competitive position of our high performance forgings and castings business.”

Mr. Harshman continued, “I would like to thank Gary Vroman for his more than 30 years of contributions and leadership that helped make ATI Ladish a technology leader in high performance forgings and castings. Gary’s support and efforts were critical to the successful integration of ATI Ladish upon the completion of ATI’s acquisition of Ladish in May 2011. We wish Gary well in his future endeavors.”

Mr. Sims will remain responsible for ATI’s tungsten materials business until the completion of the sale of the business.
