Mario Longhi Steps Down as CEO of US Steel

“Mario played a key role in driving the company’s transformation, including the successful implementation of The Carnegie Way,” said 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 began his tenure at US Steel in 2012 as executive vice president and chief operating officer. In 2013 he succeeded John Surma as CEO and was elected to the board of directors. Under Longhi’s guidance, US Steel embarked on a business transformation known as The Carnegie Way. He led the steel industry in its pursuit of fair trade, providing testimony to Congress on the impact of unfairly priced imports on domestic producers, and initiating trade cases as necessary.

“When I came to the company, I envisioned a five-year tenure, which I have completed,” said Longhi. “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.”
