NEW YORK Mario Longhi, president and chief operating officer of U.S. Steel Corp., has been appointed chief executive officer effective Sept. 1, the company said late Aug. 16.
Longhi, who joined the Pittsburgh-based steelmaker last year, will succeed John P. Surma, who will retain the position of executive chairman through Dec. 31, when he will retire from the company and its board of directors.
The move comes just months after Longhi was named president of the integrated steel producer (amm.com, May 30). He joined the flat-rolled steelmaker as executive vice president and chief operating officer after leading Gerdau Long Steel North America. Prior to joining Gerdau, he served 23 years at global aluminum producer Alcoa Inc. (amm.com, July 2, 2012).
The company also named David B. Burritt to succeed executive vice president and chief financial officer Gretchen R. Haggerty, who will retire Aug. 31. Burritt, who served as chief financial officer and vice president of global finance and strategic services for Caterpillar Inc. from 2004 to 2010, will report directly to Longhi effective Sept. 1.
The company also said James D. Garraux, general counsel and senior vice president, will retire by the end of 2013 after 34 years with the company.
The company made a number of other management changes earlier this summer (amm.com, June 10).
