A Swiss succession buyout sells to a strategic within three years
PureGym announced on 15 October 2026 that it has signed an agreement to acquire NonStop Gym, a Swiss low-cost fitness operator founded in 2014 with 47 gyms and more than 100,000 members, for GBP 235 million. Completion is expected on 2 November 2026. PureGym, majority-owned by Leonard Green & Partners with KKR as a minority investor, ran 49 Swiss gyms at 30 June 2026.
The Riverside Company announced on 13 October 2026 that its European fund has invested in Abovo of Selzach, a distributor of cleanroom consumables, Henkel adhesive technologies and ESD accessories, as the seventh add-on to Dastex Group, which Riverside has backed since May 2023.
Simwell International of Laval, Canada, acquired all 200 shares of ProcSim Consulting Sàrl of Ecublens from its three partners, according to the commercial register notice published on 13 October 2026.

A sponsor turned out to be the first step, not the exit. Invision bought into NonStop Gym in late 2023, with the founders staying on. Three years later it sells the 47 gyms to PureGym for GBP 235 million, about GBP 5 million a gym. NonStop is strong where PureGym is absent, in French- and Italian-speaking Switzerland, so the buyer gets a national network in one step.
Foreign platforms keep buying Swiss specialists. Riverside's Dastex, a German cleanroom-supplies group, bought Abovo of Selzach, its seventh add-on since 2023. Lineal, a US legal-technology firm, bought Forentec of Dübendorf, 28 people in digital forensics, and keeps founder Lionel Bloch to run its European base.
One sale showed up only in the register. ProcSim of Ecublens, which simulates logistics processes, was sold by its three partners to Simwell of Laval, Canada. Of 17 merger and transfer filings this week, it was the only one between different owners.
Estates with something to buy. Ganz Installationen of Volketswil, a heating and plumbing installer founded in 1952, went bankrupt on 8 October; its service customers are the asset. Renergon of Lengwil, a builder of biogas plants, followed on 6 October.
When a Big Four auditor arrives at an owner-run company
We traced 1,750 Swiss companies that took on a Big Four auditor between 2017 and 2024 and followed each for two years. 13.5% were sold in that time, but a fifth of the arrivals were whole groups switching on the same day, often subsidiaries a buyer already owned and was folding in. This week's filings include one of that kind: Swiss Post Cybersecurity, a Swiss Post subsidiary, moved from BDO to Ernst & Young.
The arrivals that matter to a buyer are the rare ones at owner-run companies that keep their board: about five a year. 12.8% of those were sold within two years, against 2.5% of comparable owner-run companies, about five times as often. The sample is small, 39 cases with 5 sales, so read it as a direction, not a rate. An owner who pays for a Big Four audit usually wants numbers a bank, an investor or a buyer will accept.

PureGym← NonStop GymGE
NonStop Gym, founded in 2014, runs 47 low-cost gyms with more than 100,000 members, mainly in French-speaking Switzerland. PureGym signed on 15 October to buy it from Invision for GBP 235 million, with completion set for 2 November. Together with PureGym's 49 gyms in German-speaking Switzerland, the network will pass 100 gyms by the end of 2026.
Abovo of Selzach distributes cleanroom consumables, Henkel adhesive technologies and ESD accessories to life-science, semiconductor, aerospace and watchmaking customers across Switzerland. Riverside's European fund bought it on 13 October as the seventh add-on to Dastex Group, the German cleanroom-supplies platform it has backed since May 2023. Managing director Markus Kaufmann joins the group. A Swiss niche distributor is the kind of add-on a European buy-and-build platform keeps buying.
Forentec of Dübendorf, founded in 2015, does digital forensics, e-discovery, cybersecurity and open-source intelligence for law firms, companies, insurers and authorities, with 28 full-time staff. Lineal of Kansas City, a legal-technology provider with 290, announced the purchase on 14 October. Founder Lionel Bloch and the team stay, and Dübendorf becomes Lineal's base for Europe, the Middle East and Africa.
Impag of Zurich, a specialty-chemicals distributor backed by Deutsche Private Equity, bought Broadways Chemtech of Mumbai, which has distributed construction and coatings chemicals in India for more than 24 years. The business becomes Impag India, and owner Chirag Shah stays through the transition. It follows Impag's purchase of Comindex of Spain earlier this year.
Galderma of Zug agreed on 14 October to buy ZO Skin Health of California, a physician-dispensed skincare brand, from shareholders including Blackstone funds and the Obagi family, for an enterprise value of USD 1.5 billion in cash. ZO had net sales of about USD 330 million in the twelve months to June 2026, so the price is about 4.5 times sales. Closing is expected around the turn of the year.
Simwell International inc.← ProcSim Consulting Sàrl
ProcSim Consulting of Ecublens, registered since 2007, models and simulates logistics processes and sells the software for it. Published 13 October: its three partners, Simon Farsa, Charbel Hayek and Antoine Hayek, sold all 200 shares to Simwell International of Laval, Canada, a simulation and optimisation consultancy, and Alexandre Ouellet of Laval became managing officer. We found no announcement of the sale.
Klarent of Zurich, founded in 2023 by former Google engineers Asheem Panakkat and Momchil Ivanov, uses AI to write software tests that then run deterministically, without AI. The seed round pays for expansion into the United States and for more engineers.

Renergon International AG in Liquidation TG · Biogas plant engineering · est. 2014
bankruptcy
The Kreuzlingen district court opened bankruptcy on 6 October 2026, published 15 October. The Lengwil company plans and builds biogas plants that use solid-state (dry) fermentation, a process for stackable organic waste, and has sold them abroad as well as in Switzerland. Its plant designs, process know-how and the operators of existing plants, who need service and spare parts, are what a biogas or waste-to-energy engineering firm would look at.
Ganz Installationen AG in Liquidation ZH · Heating, plumbing and ventilation · est. 1952
bankruptcy
The Uster district bankruptcy court opened bankruptcy on 8 October 2026, published 15 October. The Volketswil installer, founded by Hermann Ganz in 1952, plans, installs and maintains heating, plumbing, ventilation and cooling systems, runs a 24-hour emergency service and trains apprentices. Its service customers in the Glatt valley, its maintenance contracts and its installers are what a building-services firm in the Zurich area could take over quickly.
CEMAPS SA en liquidation VS · Pharmaceutical formulas and licensing · est. 2007
bankruptcy
The Sion district court declared the company bankrupt on 6 October 2026, published 12 October. Registered since 2007, CEMAPS holds pharmaceutical formulas, licenses patents and inventions, and makes and sells pharmaceutical, dietary and cosmetic products, notably under the EDELWEISS LAB brand. The formulas, the brand and any product registrations are assets the liquidator can sell separately, and a contract manufacturer or a cosmetics brand owner is the natural buyer.

Based on 6,079 SOGC/SHAB publications processed this week. M&A data sourced from Swiss commercial registry filings (1 SOGC), press-reported transactions via web intelligence (6 EXA), and startup funding from Startupticker, Tech.eu, and company disclosures (2 rounds). Company distress scoring based on proprietary multi-signal model across 113,000 Swiss companies. Register deal counts exclude merger and asset-transfer filings whose notice states that one owner held every share of both companies, and demergers. This week 12 of 17 such filings stated common ownership; PPM exclusive Services' merger with Terra Gastro, B&C Agromercantil's contribution of its Brazilian subsidiary and the deletion of Universal-Job's Rapperswil branch are also within groups. Press items rejected on review: GR3N's EUR 15.5 million Series B (announced in June 2026), Quantisimo's planned SPAC listing (a WISeKey group transaction announced on 9 October), the Ticino government's proposal to buy out Alloggi Ticino (a proposal to parliament, not a deal), and A+B Electronic (a German target with no Swiss party). Pre-deal signals dropped on review: Swiss Post Cybersecurity and Biotest (Schweiz) (auditor changes inside a group), CGN Belle Epoque (publicly owned), Forum 4 (capital paid in, not increased) and Same Deutz-Fahr Schweiz (the Swiss arm of an Italian group, so its board change is not a family handover). Forward radar left empty this week: the highest-scoring names were either already bankrupt or showed only routine board changes. Sika's purchase of Azpects of Ipswich, announced 9 October, was left out for space.
