Everton have endured a tumultuous few seasons before the takeover was completed in December.
Pickford has played a major role in helping Everton retain their Premier League status despite managerial sackings, financial rule breaches and points deductions.
Manager David Moyes sees Pickford as key players in his side alongside defenders James Tarkowski and Jarrad Branthwaite, who signed a new five-year deal in July.
Pickford has won 76 caps, second only to Peter Shilton among England keepers.
Pickford has played at three major tournaments, reaching the 2018 World Cup semi-finals and the finals of Euro 2020 and Euro 2024.
James Trafford’s move from Burnley to Manchester City in July may have eclipsed Pickford’s record signing fee, although the figure is disputed.
City sources say the move is worth £27m plus add-ons, but Burnley sources put the figure at £31m plus add-ons and a sell-on clause.
