Following the box office success of Teenage Mutant Ninja Turtles, Paramount Pictures and Nickelodeon Movies officially announced that a sequel was greenlit.

Principal photography on the film began in April 2015, in New York City, and wrapped up in August 2015.

Out of the Shadows premiered at Madison Square Garden in New York City on May 22, 2016, was released in theaters in the United States on June 3, 2016. The film received generally mixed reviews from critics, who praised its performances, action sequences, visual effects, and musical score; deeming it an improvement over its predecessor. However, it was a box-office bomb and grossed only $245 million against a $135 million budget, resulting in a planned third film being scrapped in favor of an animated reboot, Mutant Mayhem, released in 2023.
