McDonald's announced on Sunday that it had fired CEO Steve Easterbrook after the corporation found that he had "demonstrated poor judgment" by engaging in a consensual relationship with an employee.
The company has since named Chris Kempczinski as the new CEO. Kempczinski was formally the president of McDonald's USA.
"Chris takes the reins of this great company at a time of strong, sustained performance, and the board has every confidence that he is the best leader to set the vision and drive the plans for the company's continued success," McDonald's said in a statement.
Easterbrook had been CEO since March 2015 and previously served as the company's chief brand officer and head of operations in the U.K. and northern Europe.
Kempczinski said he is looking forward to the challenge.
"I'm thrilled to be leading this incredible company," Kempczinski said in a statement. "Working alongside our talented team, our board, our franchisees and suppliers, I am committed to upholding our rich heritage of serving our customers and driving value for our shareholders and other stakeholders."
