But is the arrival of the Miami-based multi-club investors good news for Toffees fans?
Well, a look at their record since diving into the world of football club ownership won't be an easy read for the Goodison Park faithful.
Moshiri, who became the majority owner of the club in 2018, reached an agreement to sell his shares of 94.1 per cent to 777 on Friday.
Should the deal go through, Moshiri's ownership has come to an end with the building of a new stadium, hiring former rival manager Rafa Benitez and two years of Premier League relegation battles sitting fresh in the memory of Evertonians.
"I have spoken to a number of parties and considered some strong potential opportunities," Moshiri said in a statement. "However, it is through my lengthy discussions with 777 that I believe they are the best partners to take our great Club forward, with all the benefits of their multi-club investment model."
