Business Valuation: Environmental Technology

The average Swiss Environmental Technology company is valued at 4.5 - 6.5× EBITDA on a statutory (tax-based) basis and 6.0 - 8.5× EBITDA in actual deal transactions. The spread between statutory and deal multiples represents a key arbitrage opportunity for informed buyers. The current market trend is rising, with an arbitrage gap rated as medium. Actual valuations depend heavily on recurring revenue share, customer diversification, management depth, and equipment modernity.

Key valuation drivers include: The only Swiss industrial niche in this series where employment is measurably growing: NOGA divisions 36 to 39 went from 18,091 employees in 2012 to 22,973 in BFS STATENT 2024, a rise of 27.0%; Sewerage is the standout — division 37 grew employment 45.7% over twelve years, from 4,229 to 6,161, against electrical equipment manufacturing at -24.0% over the same period. Factors that can compress valuations include: The niche is far smaller than commonly stated. The measured core is 22,973 employees, not the roughly 64,000 carried in the February 2026 edition of this report — that number can only be reached by counting engineering and equipment firms in other NOGA divisions; Growth in headcount is not the same as growth in margin: much of the expansion is public-sector and utility employment where pricing is regulated and the operator is not competing for the work. Deal multiples typically range from 6.0 - 8.5× EBITDA, but actual prices vary significantly based on customer concentration, management quality, revenue predictability, and geographic reach within Switzerland's 26 cantons.

This is one of the few Swiss niches where the question has a measured answer rather than an estimate. BFS STATENT 2024 records 2,253 establishments in NOGA divisions 36 to 39 — water supply, sewerage, waste collection and treatment, and remediation — employing 22,973 people, against 1,999 establishments and 18,091 employees in 2012. That is employment up 27.0% over twelve years, with sewerage alone (division 37) up 45.7%, from 4,229 to 6,161. Over the same period electrical equipment manufacturing fell 24.0% and printing fell 45.1%: this is the one industrial niche in the series where the measured trend runs upward. The February 2026 edition of this report gave roughly 1,800 companies and roughly 64,000 employees. The company count was understated; the employment count was overstated by roughly a factor of three, because 64,000 can only be reached by including engineering consultancies (NOGA 71), equipment manufacturers (NOGA 28) and construction firms that sit outside the environmental divisions entirely. Both figures are given here with the divisions they refer to, because which population is being counted changes the answer completely. The demand behind the sewerage figure is documented: the Federal Office for the Environment reports that of the 22 micropollutants regulated with ecotoxicological limits in the Waters Protection Ordinance — 19 pesticides and 3 pharmaceuticals, in force since April 2020 — 18 exceeded their limit in 2022, and only six of the 38 watercourses examined that year complied. The commercial register also removes one name: there is no Swiss entity registered as Hitachi Zosen Inova, which headed the February 2026 key-player list. The company is registered as Kanadevia Inova AG in Zurich.

Succession in Swiss environmental technology is being decided in the one niche of this series where the measured trend is up. BFS STATENT 2024 records 22,973 employees in NOGA divisions 36 to 39, against 18,091 in 2012 — a rise of 27.0% — with sewerage alone up 45.7% over those twelve years. Set that beside electrical equipment manufacturing at -24.0% and the buyer's interest becomes easy to explain. It also means the discount an owner usually has to argue against is not there: the sector story supports the price. What replaces it is a different set of questions. The first is what the growth actually is. Much of the division 36 to 39 expansion is public-sector and utility employment, where pricing is regulated and no one is competing for the work; a private engineering practice or equipment supplier is not automatically riding that curve, and the seller needs to show where their own revenue sits inside it. The second is the qualification, and it is the sharper of the two. Wastewater process design, contaminated-site permitting and drinking-water work are sold on named engineers with references and cantonal standing. Hunziker Betatech AG, TBF + Partner AG and CSD Ingenieure AG each operate from six or more registered locations precisely because that reputation is local and personal. An owner who cannot name who holds which reference, and who will still be there in three years, is selling a discount into the process. The third is the tender book. Municipal and cantonal procurement runs on multi-year frameworks that are formally scored and openly contestable; a buyer is paying for renewal probability, not for last year's revenue, and that means showing the framework list with expiry dates and the win rate on rebids. Owners should separate regulated recurring work from project work, document every qualification and its holder, show the framework renewal calendar, and allow two to three years of overlap. Deal multiples for the sector typically run 6.0 - 8.5× EBITDA.

Four trends define the sector in 2026: (1) The one Swiss industrial niche where employment is measurably growing — BFS STATENT 2024 records 22,973 people in NOGA divisions 36 to 39 — water supply, sewerage, waste collection and treatment, and remediation — against 18,091 in 2012, a rise of 27.0%. (2) A regulated demand driver with decades left to run — The Federal Office for the Environment reports that of the 22 micropollutants regulated with ecotoxicological limits in the Waters Protection Ordinance — 19 pesticides and 3 pharmaceuticals, in force since April 2020 — 18 were found exceeding their limit in 2022, and only six of the 38 watercourses examined that year complied. (3) The niche is a third of the size the previous edition implied — The February 2026 edition of this report gave roughly 1,800 companies and roughly 64,000 employees. (4) The sector name in the register has changed, and two more are wrong — There is no Swiss entity registered as Hitachi Zosen Inova. The company is registered as Kanadevia Inova AG in Zurich, SHAB 24 April 2026, with Kanadevia Inova Low-C Energy AG at the same seat; the February 2026 edition headed its key-player list with the former name.

The principal acquisition risks are: (1) Public budgets are political. A cantonal or municipal deferral moves a treatment plant upgrade by years, and the supplier has no commercial lever to accelerate it; (2) Consolidation among the engineering firms themselves — CSD Ingenieure AG, Hunziker Betatech AG and TBF + Partner AG each already operate from six or more registered locations, and scale in tendering compounds; (3) Technical qualification concentrated in individuals. Wastewater process design and remediation approvals sit with named engineers, and a succession that loses them loses the references the practice bids on. Buyers should conduct thorough due diligence on customer concentration, regulatory compliance, and key-person dependencies. Deal multiples of 6.0 - 8.5× EBITDA may be discounted for firms with elevated risk profiles.

The typical cost breakdown for a Swiss Environmental Technology firm is: Personnel Costs (engineers, project managers, technicians): 35%, Equipment & Systems (filtration, treatment, monitoring): 22%, Materials & Consumables: 14%, Subcontractors & Specialist Services: 10%, R&D and Permitting: 7%, Other Operating Costs: 4%, Profit Margin (EBITDA): 8%. Indicative split for a Swiss environmental technology business. The mix depends on which half of the niche the company sits in: an engineering practice such as Hunziker Betatech AG or CSD Ingenieure AG carries staff cost as the dominant line and bills against public framework contracts, while a plant builder or instrument maker carries materials and components. Demand on both sides is set by ordinance rather than by the industrial cycle, which is why NOGA divisions 36 to 39 grew employment 27.0% between 2012 and BFS STATENT 2024 — sewerage alone 45.7% — while electrical equipment manufacturing fell 24.0%. For the equipment side only, Swissmem reported capacity utilisation of 81.1% in Q2 2026 against a long-run average of 85.6% (2015-2025); for the services side that measure has no meaning. These benchmarks are important for buyers assessing operational efficiency and margin improvement potential post-acquisition.

Switzerland's main Environmental Technology clusters are: (1) Greater Zurich and Zug (ZH, ZG) — The densest concentration in the niche. Kanadevia Inova AG and Kanadevia Inova Low-C Energy AG build waste-to-energy plants from Zurich, TBF + Partner AG engineers from Zurich, Hunziker Betatech AG from Winterthur, Bucher Municipal AG builds municipal equipment in Niederweningen, Kärcher AG is registered in Dällikon, and Rittmeyer AG supplies automation and telemetry from Baar (ZG). (2) Northwestern Switzerland (BL, BS, AG, SH) — Instruments and piping. Endress+Hauser AG is registered in Reinach (BL), Georg Fischer AG in Schaffhausen and Georg Fischer JRG AG in Sissach (BL), and CSD Ingenieure AG holds a registered location in Pratteln. (3) Bern region and central Switzerland (BE, LU, UR) — Engineering headquarters and federal proximity. CSD Ingenieure AG is registered in Bern with further locations in Kriens and Altdorf (UR); Hunziker Betatech AG and TBF + Partner AG both hold registered Bern locations. (4) Western Switzerland and Ticino (VD, GE, TI) — Present through branches rather than headquarters. TBF + Partner AG is registered in Geneva and Lugano, Hunziker Betatech AG in Lausanne and Bellinzona, Rittmeyer SA in Avry (FR) and Bellinzona, and Kärcher SA in Villars-Sainte-Croix (VD). Regional concentration affects valuations, as companies in established clusters benefit from supplier ecosystems, specialized talent pools, and industry networks.
