Everard joined Wasps in the summer after four years at Leicester Tigers - and he has made an immediate impression.
And the 20-year-old is thrilled to have secured a deal to remain at the club.
Everard said: "I've learned so much in my first few months with the club and I'm thoroughly enjoying getting a run in the team.
"We've got a lot of great young players here and it's great for me and those guys that we get regular chances to play.
"You only have to look at the impact other young players like Christian Wade and Joe Launchbury are making this season to see that we've got the basis for a good future here and I am really pleased to be part of it."
Wasps boss Dai Young added: "Matt is a young player with a fantastic attitude and he's worked really hard in his first few months with the club.
"He's learning all the time from the more experienced guys around him and I have no doubt he'll continue to improve."
