Acrevis Bank and Regiobank Männedorf (RBM) are joining forces. Subject to approval by the shareholders of both companies and by Switzerland’s financial market regulator Finma, the transaction is expected to be completed in the form of an absorption merger by mid-year.

RBM will be integrated into Acrevis and will operate under the new name «Acrevis Bank Männedorf.»

Transaction Volume of 25,8 Million Francs

As a first preparatory step, Acrevis plans a 1-for-5 stock split. This means that each Acrevis shareholder will receive five shares for every existing Acrevis share. As part of the transaction, RBM shareholders will receive 17 Acrevis shares per RBM share, plus a cash compensation of 200 francs.

The valuation of RBM represents a 29,9 percent premium to the volume-weighted average share price of the past 60 trading days. The total transaction volume amounts to 25,8 million francs. Acrevis will finance the transaction primarily through a capital increase within its existing capital band.

The merger brings together two banks characterized by strong regional roots, similar business models, and a shared set of values, the statement said. The aim is to combine the strengths of both institutions and further develop them under the Acrevis umbrella.

RBM is the smallest bank in the Lake Zurich region. It employs 11 staff and had total assets of 439,7 million francs as of mid-2025. Client deposits amount to 296,7 million francs, and client loans to 351,3 million francs.

Despite its size, the bank offers a comprehensive range of services, including traditional account products, mortgages, in-depth investment advisory services, and corporate loans.

Acrevis Ten Times Larger

Acrevis Bank, headquartered in St. Gallen, had total assets of 5,1 billion francs as of mid-2025, client deposits of 3,7 billion francs, and client loans of 4,2 billion francs. Around 190 employees work at eight branches between Lake Constance and Lake Zurich.

The merger offers RBM an attractive future within a larger and more capable organization. Smaller banks in particular are facing increasing challenges due to ongoing regulatory and technological change, the statement added. RBM said it had examined the option of a merger at an early stage, taking into account the interests of shareholders, clients, and employees.

All employees are to be retained. The regionally tailored offering, familiar proximity, and personal client service will remain in place. RBM will in future operate as a branch under the name Acrevis Bank Männedorf.

Through the merger, Acrevis expands its market area around Lake Zurich, where it is already present in Rapperswil-Jona, Lachen (SZ), and Pfäffikon (SZ).

«The merger enables us to expand our market presence and strengthen our long-term competitiveness,» said Acrevis Chairman Stephan Weigelt. «The proven values and regional proximity to RBM’s clients form the foundation for a successful integration.» The step meaningfully complements the bank’s existing strategy. Acrevis also has the necessary structure, organization, and capital base to implement the merger sustainably and successfully.

To approve the merger, RBM shareholders will vote on the proposal at the Annual General Meeting on March 26, 2026. Acrevis will hold its AGM on March 27, 2026.

The merger is expected to be completed by mid-year and will take effect retroactively as of January 1, 2026.
