The company started international expansion in 2009 and operated 61 multiplexes in 12 countries as of 2021.

Cineplexx Kinobetriebe GmbH was founded in 1993 as a joint venture between Constantin Film-Holding GmbH and Vienna's own cinema and event companies (KIBA / Wiener Stadthalle and Wiener Holding AG). The city of Vienna withdrew and sold its shares to Constantin Film-Holding GmbH in spring 1999. Constantin Film-Holding GmbH and Cineplexx Kinobetriebe GmbH are wholly owned by the Langhammer family.

The first Cineplexx cinema was opened on October 31, 1996 in Graz. It was after the Apollo Cinema reopened in December 1993 by Cineinvest, a subsidiary of Constantin Film Holding and Kiba. The largest Cineplexx which was built in November 1999 on the Danube plate, in Reichsbrücke, included 13 halls and 3,400 seats but was closed in 2011.
