Troy A. Clarke has been appointed president and CEO of Navistar International Corp. (IW 500/86), effective April 15, 2013. Clarke, currently the company's president and chief operating officer, will also join the board.

Lewis B. Campbell, who has served as executive chairman and interim CEO since August 2012, will step down from those positions and from the board.

"Over the past six months, Navistar has made significant progress on many important fronts, including on our three near-term priorities: improving quality, meeting each of our clean engine launch milestones, and delivering on our 2013 operating plan," Campbell said. "When I assumed the interim CEO role last August, I was prepared to stay as long as necessary to oversee the company through a transition period, and today I am pleased to announce our turnaround is firmly underway and our return to profitability is clearly in sight. I am also delighted that the board and I have decided that Troy is the right executive to lead the company forward at this time, and I am confident Navistar will continue to build on its momentum – improving performance and quality for customers and creating shareholder value."

James H. Keyes, who has served as a board member since 2002, will become non-executive chairman.

"We believe that separating the chairman and CEO roles at this time will enable Troy to focus exclusively on continuing to successfully execute the company's turnaround plan and putting the company on a path to profitability entering fiscal year 2014," Keyes added.

He has a B.S. in mechanical engineering from General Motors Institute, as well as an M.B.A. from the University of Michigan.
