The 25 largest mergers in Switzerland (last 12 months)

The Swiss commercial register published 1,039 mergers over the past twelve months. The largest by absorbed assets include major international consolidations and domestic group restructurings.

AXA Versicherungen in Zürich absorbed CHF 1.2 billion in assets in November 2025, a consolidation within the AXA group's Swiss operations. Mitrelli Group Swiss in Thurgau absorbed CHF 739 million in January 2026, and Mayer & Cie Holding in Zug absorbed CHF 498 million in May.

Zürich leads by merger count with 219, followed by Bern (125) and Zug (110). The total absorbed assets across all 1,039 mergers amount to CHF 10.3 billion. A merger puts existing supplier contracts on both sides in line for review, though the register says nothing about when that review starts.

Mergers in the Swiss register are published when one company absorbs another (Fusion durch Absorption). The absorbing company inherits the assets and liabilities of the absorbed entity. The "absorbed assets" column shows the total assets transferred, as declared in the SHAB publication. To understand how these events appear in the register, see our guide to reading SHAB/FOSC.
