Walton is to be replaced by Jeff Carr, currently FD at Associated British Foods.
The resignation comes after Walton served five years with the company and follows results earlier this week showing revenues up 17% to £1bn.
Speaking to Accountancy Age Walton said the airline would not publish results under international accounting standards until all the new rules had become clear.
Reflecting on the company’s reparations he said: ‘Until we have clarity, we won’t publish any figures.’
The results also saw easyJet predict difficult times ahead for the industry.
A spokesman said Walton would work a handover period of up to three months, and had ‘irons in the fire’ for his next move.
