PRESS RELEASE

Ad hoc announcement pursuant to Art. 53 LR

Rotkreuz, 24 April 2026

mobilezone has been informed that Haubrich Holding SE, currently holding 5.18% of outstanding share capital and therewith largest single shareholder of mobilezone holding ag (“mobilezone”), will sell its entire stake to JULE Investment Management AG at the time of completion of mobilezone’s acquisition of AK Group AG (Apfelkiste and Marein). JULE Investment Management AG is owned by Pierre Droigk, the founder of Apfelkiste.ch.

The Haubrich family invested in mobilezone in the course of mobilezone’s acquisition of SH Telekommunikation Deutschland GmbH in June 2019. From April 2020 until the most recent Annual General Meeting on 8 April 2026, Michael Haubrich represented the family on the Board of Directors of mobilezone. Following the divestment of mobilezone’s German business and the associated strategic focus on the Swiss market at the end of 2025, the Haubrich family decided to sell its shareholding.

According to mobilezone’s information, JULE Investment Management AG, a company owned by Pierre Droigk, will acquire the entire shareholding (5.18% of the outstanding share capital) from the Haubrich family at the time of completion of mobilezone’s acquisition of Apfelkiste and Marein. Following the announcement of mobilezone’s acquisition of AK Group AG (“Apfelkiste”) on 19 March 2026 (link), mobilezone considers Pierre Droigk’s investment to be an important step in strengthening mobilezone’s shareholder structure and a strong vote of confidence in the future joint potential of mobilezone, Apfelkiste, and Marein. As communicated on 19 March 2026, the Board of Directors of mobilezone will propose Pierre Droigk for election to the Board of Directors at the next Annual General Meeting on 31 March 2027.

Completion of the transaction is expected by 30 June 2026 at the latest.
