ONE swiss bank consolidates its growth

ONE Swiss bank prepares a merger with Banque Profil de Gestion and acquires a client portfolio to consolidate its growth

We are pleased to announce that ONE swiss bank SA (ONE) shareholders have signed a binding Memorandum of Understanding (MoU) with Banque Profil de Gestion SA (BPDG) and its current majority shareholder, Banca Profilo S.p.A. (Profilo) for the sale of a majority stake of 60.4% in BPDG by Profilo to ONE’s shareholders. The transaction shall take place in the first quarter of 2021, followed by the merger of the two banks.

The assets under management of the merged entity will reach CHF 4 to 5 billion once the operation is completed. The aim of the involved parties is to strengthen synergies between their private banking and asset management divisions (ex-Dynagest, acquired by BPDG in 2018).

The transaction is subject to the formal approval of the relevant financial supervisory authorities. Consecutive to the merger, the bank will operate under a single identity and management bodies will be adjusted to reflect the changes in the shareholder structure.

Alongside the signing of this MoU, ONE has concluded an asset purchase agreement with Falcon Private Ltd. in Zurich for the transfer of its entire client portfolio. This deal is expected to be fully executed during the first quarter of 2021, prior to the merger with BPDG. In order to better serve its expanded client base, ONE, which already has offices in Geneva and Lugano, will establish a new presence in Zurich with 10 to 15 employees.

Grégoire Pennone, CEO and representative of ONE’s shareholders, comments: “These two transactions are in line with the actions taken in recent years and offer promising perspectives for ONE. Thanks to the expertise of the two companies, we will be able to offer a wider range of products and services and meet our clients’ present and future expectations.”

Our entrepreneurial mindset motivates us to rethink our value proposition continually.

A history with strong convictions

1984 TO 2019

ONE Swiss Bank was born from the merger between the family-owned private banks GS Banque, founded in 2004 under the name Banque Bénédict Hentsch & Cie, then renamed Geneva Swiss Bank in 2014, and Banca Arner, founded in 1984.

ONE swiss bank is the result of a successful merger between two banks driven by a strong desire to bring added value to the wealth management industry and sharing a common vision to develop an authentic and truly modern private banking model.
