One of the US steel industry’s executive titans, Mario Longhi, has announced his retirement from US Steel.

Mr Longhi stepped down as CEO, according to the company, on 8 May, but will remain on the board of directors and serve as an employee, providing transitional support, until his retirement.

On the day Longhi stepped down, current president and Chief Operating Officer David B Burritt stepped into Longhi’s shoes. He was elected to assume the position of president and CEO and become a member of the board.

According to US Steel’s chairman David S Sutherland, Longhi played a key role in driving the company’s transformation, including the implementation of The Carnegie Way.

“His impact was felt across our company and the steel industry through his efforts in Washington DC to combat unfair trade and create a level playing field,” Sutherland added.

Longhi’s career with US Steel started in 2012 when he was appointed executive vice president and chief operating officer. He was promoted to president and CEO a year later and elected to the board.

The much-praised Carnegie Way, developed and implemented by Longhi has generated marked cultural and operational improvements within the company.

“When I came to the company, I envisioned a five-year tenure, which I have completed,” Longhi said, adding that he was proud of the progress made by the business, “which solely resides on the people of this company”.

According to Longhi, US 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,” he said.
