Everton trio Joseph Yobo, Tim Howard and Phil Jagielka have signed contract extensions with the club.
All three had agreed to their new deals in the last few weeks but now the formalities have been completed.
Defender Jagielka, currently sidelined after knee surgery, was the Toffees' player of the season.
Yobo was the first signing of manager David Moyes in 2002, while keeper Howard joined on loan in 2006 and signed a permanent deal in 2007.
Former Sheffield United man Jagielka was part of Everton's first-choice centre-back partnership alongside Joleon Lescott last season, but that was no bar to Nigeria international Yobo signing a new deal.
I have been pleased with the way we've gone about our business
Everton manager David Moyes
"It's great that three valuable members of the squad have committed themselves to the club for a lengthy period," said Moyes.
"Tim, Phil and Joseph have been big players for us over the last few years and it's great news that they will continue to be so for the foreseeable future.
"I have been pleased with the way we've gone about our business. We spoke to Phil, Tim and Joseph and we got everything done and dusted efficiently and quietly, which is the way we like things to be done."
Moyes has already stressed he has no plans to sell any players from his squad, but he acknowledges he has to strengthen if he is to have any chance of improving on last season's fifth-place finish in the Premier League.
Everton were devastated by serious injuries, with Jagielka's ruptured knee ligament the last in a long line which saw the seasons of Aiyegbeni Yakubu (Achilles), Mikel Arteta and Victor Anichebe (both knee) ended prematurely.
Further injuries to Louis Saha, James Vaughan and Nuno Valente saw the Toffees play most of December and January without a recognised centre-forward.
