“This is the next step in our strategy to reposition ATI as an aligned and integrated specialty materials and components business. Consolidating the leadership of this segment under John Sims will accelerate the alignment and integration of the separate business units that comprise this segment,” says Rich Harshman.  “I believe there are additional opportunities to further align, streamline, and improve the operating efficiencies, and enhance the competitive position of our High Performance Materials and Components segment. Sims has knowledge and leadership experience involving each of the business units comprising this segment.”

“We see additive manufacturing as an important component of ATI’s long-term profitable growth strategy.
