Don Swearingen, Mitsubishi Motors North America executive vice president and chief operating officer, announced his retirement on Monday.

The executive will keep his role until June 1 to help with the transition between Mitsubishi’s newly appointed president and chief executive, Fred Diaz, and outgoing President and Chief Executive Ryujiro Kobashi.

Swearingen spent 21 years of his 40-year automotive-industry career at Mitsubishi. He was named to his current roles in 2013 and helped return the automaker to profitability in 2014.

“Sixty has long been my retirement target, and I am walking away knowing Mitsubishi is in the midst of a brand and sales renaissance,” Swearingen said in a statement.

He turns 60 this month.
