Swiss M&A in June 2026
ValIndex recorded 33 transactions involving an operating Swiss company in June 2026. 20 were reported in the business press; 13 surfaced only in the commercial register, with no press coverage at all. 18 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. 13 of June’s 33 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 21 of 33 transactions.

AK Group AG (Apfelkiste.ch and MAREIN)
acquired by Mobilezone Holding AG (SIX: MOZN)
Closing completed 1 June: mobilezone paid CHF 180M cash (EV) for AK Group — Apfelkiste.ch (60,000-SKU phone-accessory/lifestyle e-tailer, founded 2011) plus retail-branding arm MAREIN. 2025 revenue over CHF 100M, EBITDA ~CHF 20M, ~100 staff — 1.8x revenue / 9x EBITDA. Founder Pierre Droigk rolls into a 5.18% mobilezone stake, becoming its largest individual shareholder, with a 2027 board seat proposed. PE seller Invision exits. Group 2026 EBITDA guidance lifted to CHF 50-57M.

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. Announced 1 June; price undisclosed. Pure brand-and-craft consolidation in Swiss garden tools: Flisch plans to internationalize LEYAT, until now sold almost exclusively in Switzerland. Niche Swiss manufacturing heritage keeps getting absorbed by family-held strategics, not funds.

RK Diablo AG
acquired by GP Devil AG
Not motorcycles — a hidden Lucerne metal-finishing buy-and-build folding its deal vehicles. RK Diablo AG (Emmenbrücke, 2019) is Reto Koch's holdco from his Jan-2019 takeover of electroplater Galvanova AG; GP Devil AG (2017) sits at Werkstrasse 5, Malters — home of hard-chrome specialist Blaser AG, where Koch also appears in management. CHF 1.4M net assets shift as Koch collapses two acquisition holdings into one plating group nobody has mapped.

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.

Sustainable Real Estate AG

Patrimonium Holding AG (Baar) takes over Sustainable Real Estate AG, Zurich (MDs Klaus Kämpf and Marco Scheurer) effective 1 July 2026. SRE manages the SIX-listed SRES fund — CHF 475M across 30 sustainable Swiss residential properties; Patrimonium AM (CHF 5B AUM, CHF 3.7B+ Swiss real estate) becomes fund manager 1 January 2027 pending FINMA, and inherits advisory ties to Quadoro's ~EUR 785M German funds. Sub-scale FINMA asset managers are sellers — consolidation continues.

Yfood
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.

Clyde Mobility AG
acquired by AMAG Leasing AG
AMAG buries its subscription experiment without a press release: Clyde Mobility AG folds into AMAG Leasing at CHF -25.7M negative net assets — the first hard number on what the 2019-launched Auto-Abo cost. Clyde survives only as a brand ('an offering of AMAG Leasing AG'); the standalone entity didn't outlast its Jan-2024 all-electric pivot. Architect Martin Everts had already left AMAG to run IWB.

CHF 15.2M of Zurich property moves between vehicles of the same circle: FALEM (founded May 2020) is chaired by Sergio Galluccio (Feusisberg, also on Meluca Immobilien AG's board), alongside Christian Müller and Helena Oetiker Rauner; predecessor president Adrian Lüthi stepped back. FAM-into-FALEM reads as a Galluccio-linked portfolio consolidating into one holdco — consolidation mechanics, but a marker of who quietly controls CHF 15M+ of Zurich real estate.

Alessandro Lardi's Zurich multi-family office is simplifying its stack: Swisspath AG (revision waived since 2023, sole director) absorbs Swissbluecapital AG with CHF 3.2M net assets, while sister entity Swisspath Advisory AG sits in liquidation. The group — Swisspath Capital (CEO Monica Guelmani), Yachting (2018) — is post-buildout housekeeping, not new AUM. Worth tracking as the family-office roll-up tidies before its next move.

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.
