Swiss M&A in June 2026
ValIndex recorded 23 transactions involving an operating Swiss company in June 2026. 20 were reported in the business press; 3 surfaced only in the commercial register, with no press coverage at all. 8 carried a disclosed price.
Why the register-only number matters
A Swiss acquisition becomes public twice: once when someone writes about it, and once when the commercial register publishes the change of control. The second always happens; the first often does not. 3 of June’s 23 transactions never made the press — they are in this list because ValIndex reads the register itself, every publication, every week.
Where the deals were
Canton is on record for 19 of 23 transactions.

LEYAT
acquired by Flisch Group
FELCO owner Flisch Group (Flisch Holding SA, Les Geneveys-sur-Coffrane NE) acquired LEYAT, Switzerland's oldest secateur maker — founded 1917 in Valais, now headquartered in Bevaix NE with ~20 employees.

Niche Swiss manufacturing heritage keeps getting absorbed by family-held strategics, not funds.

Grob Kies AG
acquired by KIBAG
Textbook succession: the Grob family sells its ~160-year-old Toggenburg gravel/concrete firm (3 gravel pits, 4 concrete plants, 50 staff, all retained) with no family successor. Split sale — building materials, transport and recycling go to KIBAG per July 2026; the construction unit goes to local E. Weber AG per August. KIBAG (family-owned, Zurich, founded 1926, 2,000+ employees, 14 gravel works and 25 concrete plants) keeps consolidating aggregates — strategics move fast on pit assets where PE rarely competes.

acquired by Nestlé S.A.
Nestlé announced 3 June it buys out the remaining ~51% of Munich meal-replacement brand Yfood from co-founder-CEOs Benjamin Kremer and Noël Bollmann (transfer effective 3 July 2026), having held 49% since 2023. Bloomberg pegs the implied valuation at ~€450M on 2025 sales of ~€150M with double-digit growth. Both founders exit; Nestlé's Jolanda Schwirtz takes over. First acquisition under new CEO Philipp Navratil — staged minority-to-control exits remain the corporate playbook PE must price against.

How this list was built
Every week ValIndex reviews all Swiss commercial-register publications (SOGC/SHAB) and the Swiss business press, and records transactions involving an operating Swiss company. This page is the June 2026 slice of that record. Transactions are deduplicated on the target–acquirer pair and dated to the publication or announcement, not to signing. Coverage of the register is complete for this month; press coverage is necessarily selective, which is the point of the register-only count.
