In an interview to Screen Rant, Feige revealed there would be a deleted scene, a tribute, and some "extra surprises" for fans in re-release.
"Not an extended cut, but there will be a version going into theaters with a bit of marketing push with few new things at the end of the movie. If you stay and watch the movie, after the credits, there'll be a deleted scene, a little tribute, and a few surprises," he said.
The re-release comes just a few days before the premiere of "SpiderMan Far From Home", giving fans the opportunity to revisit "Avengers Endgame" before catching up with Peter Parker on his next solo adventure.
However. "Avengers Endgame" is still about $45 million away from matching the box office record set by "Avatar", and re-release is likely to help it inch closer.
