In June 2023, UBS Group AG completed the legal close of the acquisition of Credit Suisse Group AG, a pivotal moment in UBS’s history and an opportunity to create an even stronger Investment Bank.

The legal merger of Credit Suisse AG with UBS AG, also known as the Parent Bank Merger (“PBM” or “legal merger”), was completed on 31 May 2024, marking a key milestone in our integration journey. Following completion of the PBM, Credit Suisse AG’s business transferred to UBS AG, with Credit Suisse AG ceasing to exist. Although the two entities have now legally merged into one entity, they have not yet operationally merged; as such, we continue to have two sets of contracts, operational infrastructure and processes for a transitionary period.
