U. S. Steel's Mario Longhi Steps Down, Announces June Retirement

In a statement, U. S. Steel said Mario Longhi will be succeeded by president and chief operating officer David B. Burritt, who also will join the board of directors.

“Mario played a key role in driving the company's transformation, including the successful implementation of The Carnegie Way," said U.S. Steel board chairman David S. Sutherland.

"His impact was felt across our company and the steel industry through his efforts in Washington, D.C., to combat unfair trade and create a level playing field.  We thank him for his dedication to U. S. Steel."

Longhi stepped down as chief executive on 8 May, but will assist in the transition and continue to serve on the board until his retirement on 30 June.

Longhi has been with U. S. Steel since 2012, when he was hired as executive vice president and chief operating officer.
"When I came to the company, I envisioned a five-year tenure, which I have completed," Longhi said.

"I am proud of the progress we have made, which solely resides on the people of this company. U. S. Steel employees dug in, tackled every challenge and never stopped looking for ways to improve everything they could control. I am fortunate to have spent five years working with them."
