In 2013 the club saved its existence by defeating Lyngby FC 4-2. In 2014, the rescue was secured by playing 3-3 with HB Køge. In 2015, AB finally relegated and moved down to the third tier for the first time since 1994. The 2015-16 season was a successful one for the club as it bounced back from relegation to win promotion back to the Danish 1st Division at the first time of asking under the dutiful charge of manager Per Frandsen. Despite this, however, the beginning of the season proved challenging with the club suffering a heavy defeat in the first round of the Danish Cup at the hands of rivals Lyngby Boldklub and only finishing third in its group behind Hvidovre IF and Hellerup IK to progress to the Spring promotion group. Concerns remained after a 1-0 defeat to Aarhus Fremad in the opening game of the Spring promotion round, although they quickly dissipated over the following months as AB strolled to the Danish 2nd Division title with promotion finally confirmed after a 2-1 win over Aarhus Fremad. The season came to a close following a remarkable 6-4 home victory over second placed Fremad Amager. Whilst the game saw AB lift the Danish 2nd Division trophy after the final whistle, it also proved a poignant moment for the club with a number of well regarded players, including cult hero Simon Bræmer, saying their farewells. The next season, AB could not sustain the success and ended last in 1st Division, thus relegating back to 2nd Division. In June 2012, AB was rescued from bankruptcy by a majority in Gladsaxe Municipality Council. As a result of the cooperation with Gladsaxe Municipality, the club changed its name in September 2012 to "Akademisk Boldklub Gladsaxe" to mark the club's association with the local area. AB currently has about 1,500 members and a profiled youth division which has raised talents such as Nicolai Jørgensen, Oliver Lund, Klaus Lykke and Lukas Lerager. AB operates Copenhagen Sport & Event Park centered around the facilities on Gladsaxe Stadium. AB plays their home matches at Gladsaxe Stadium (). The stadium is located on Gladsaxevej 200, Søborg, Gladsaxe Municipality, in Copenhagen, and is primarily used for football matches. The stadium has a capacity of 13,507, of which 7,707 are covered seats. The rail size is 105 x 68 meters, and the lighting is 700 lux.
