The portfolio currently consists of three investments. The investments in ACTECH (2017), WEKA (2018) and ANTENNENTECHNIK (2019) have been sold. All companies are ranked among the market leaders in their relevant markets. Since investing PREMIUM has been able to improve the positioning of companies through the management and the respective advisory boards by various measures: At ACTech, for example, production has been partly converted to 3D printers, and at Antennentechnik, the building of a new production and technology centre in Weimar has taken place, while at wekaHolzbau, the product portfolio has been expanded to include new materials. With ic! Berlin Group, the obligatory strategy workshop of PREMIUM was implemented that defined the priorities of the growth plan, among others in Asia. In July 2018 PREMIUM has acquired a majority share in CLARUS Films Group which envisages to expand its market leadership in Europe and in August 2018 KAMA, the innovation leader for post-press machines, was acquired together with the management.
