Business Valuation: Welding Technology

The average Swiss Welding Technology company is valued at 3.5 - 5.0× EBITDA on a statutory (tax-based) basis and 4.5 - 6.5× 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 stable, 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: Metals and articles of metal was one of only two positive Swiss export lines in H1 2026 at +4.2%, and 4.8% in Q2 alone (Swissmem); Genuine global positions at the top: Soudronic in can body welding, Schlatter in resistance welding of mesh and rail, Oerlikon Metco in thermal spray and laser cladding. Factors that can compress valuations include: Extreme fragmentation below the top tier, with dozens of small owner-operated firms too subscale to invest in automation or certification depth; NOGA 25 establishments fell 13.8% between 2012 and 2024, from 7,974 to 6,873, with employment down 7.4% — steady attrition at the small end. Deal multiples typically range from 4.5 - 6.5× EBITDA, but actual prices vary significantly based on customer concentration, management quality, revenue predictability, and geographic reach within Switzerland's 26 cantons.

Roughly 1,200 firms are active in Swiss welding, brazing and joining, but that is an industry estimate rather than a register count, and it understates how fragmented the sector is: the commercial register carries dozens of small owner-operated companies trading under the name "Schweisstechnik" alone, across almost every canton. Most welding work sits in NOGA division 25, fabricated metal products, which BFS STATENT 2024 records at 6,873 establishments and 83,222 employed — against 7,118 and 85,451 in 2022 and 7,974 and 89,839 in 2012. Establishments fell 13.8% over twelve years while employment fell only 7.4%, which describes consolidation at the small end rather than a shrinking industry.

Succession in Swiss welding technology is dominated by one asset that is unusually hard to transfer: certification. A weld that cannot be documented cannot be sold into rail, pressure vessel, medical or aerospace work, and the qualifications that make that documentation possible sit with named welders and welding engineers, take years to build, and do not transfer with the share register. That is the sector’s central diligence question and its central valuation risk. The structural picture is one of steady consolidation rather than decline. Most welding work sits in NOGA division 25, fabricated metal products, which BFS STATENT counts at 6,873 establishments and 83,222 employed in 2024, against 7,118 and 85,451 in 2022 and 7,974 and 89,839 in 2012. Establishments fell 13.8% over twelve years while employment fell only 7.4% — small shops are closing or being absorbed, and the work is continuing at larger ones. For a buyer, that gap is the opportunity: capacity is being released by owners retiring, not by demand disappearing. Deal multiples for the sector typically run 4.5 - 6.5× EBITDA.

Six trends define the sector in 2026: (1) A Named Company Puts Numbers on the Tariff Shock — Schlatter Industries, the SIX-listed resistance welding specialist in Schlieren, titled its ad-hoc announcements of 22 January and 27 March 2026 around fewer orders and lower revenue, with US tariffs, currency effects and cost pressures weighing on earnings. (2) One of Only Two Positive Export Lines — Swissmem records exports of metals and articles of metal up 4.2% in H1 2026, and 4.8% in Q2 alone — one of only two positive subsector lines it publishes, alongside electrical machinery at +5.5%. (3) Consolidation, Not Collapse, at the Small End — Most welding work sits in NOGA division 25, fabricated metal products. (4) The Constraint Is People, Not Machines — Tech-industry capacity utilisation stands at 81.1% against an 85.6% long-run average, but in welding that number understates how tight capacity actually is. (5) Certification Is the Moat — Welding is one of the few industrial processes where the qualification is inseparable from the product: a weld that cannot be documented cannot be sold into rail, pressure vessel, medical or aerospace applications. (6) Tariffs Reach the Sector From Both Sides — The US Section 232 duties of 10-50% on steel, aluminium and copper, in force since April 2026, hit welding twice over: once on exported equipment and once on the metal that goes into it and into every fabricated assembly.

The principal acquisition risks are: (1) US tariff escalation — 39% in August 2025, a 15% cap in November 2025, Section 232 duties of 10-50% on steel, aluminium and copper from April 2026 and Section 301 duties up to 12.5% from 24 July 2026; (2) Section 232 metal duties hit this niche twice, on exported equipment and on the steel and aluminium input itself; (3) Swiss franc strength compressing franc margins, cited by Schlatter alongside tariffs as weighing on earnings. Buyers should conduct thorough due diligence on customer concentration, regulatory compliance, and key-person dependencies. Deal multiples of 4.5 - 6.5× EBITDA may be discounted for firms with elevated risk profiles.

The typical cost breakdown for a Swiss Welding Technology firm is: Raw Materials (wire, gas, filler metals): 28%, Personnel Costs: 36%, Equipment Depreciation: 10%, Energy & Utilities: 7%, Other Operating Costs: 12%, Profit Margin (EBITDA): 7%. Skilled labour dominates the cost base, and in welding that labour is qualified rather than merely experienced: certified welders and welding engineers whose approvals take years to obtain and cannot be recruited at short notice. Consumables and shielding gas form a steady second block, bought largely from suppliers like Castolin, Messer and the Swiss arms of foreign torch manufacturers, and consumed on every job regardless of equipment investment. Metal input is the third, and it is directly exposed to the US Section 232 duties of 10-50% on steel, aluminium and copper in force since April 2026 — this niche pays that tariff twice, once on the metal it buys and once on the equipment it exports. The margin question in diligence is therefore not equipment utilisation but qualified-hour utilisation, and how much of the revenue depends on certifications that leave with the people holding them. These benchmarks are important for buyers assessing operational efficiency and margin improvement potential post-acquisition.

Switzerland's main Welding Technology clusters are: (1) Greater Zurich (ZH) — The equipment and consumables corridor. Schlatter Industries builds resistance welding systems in Schlieren, Castolin supplies consumables and hardfacing alloys from Dällikon, and Fronius runs its Swiss operation from Rümlang. (2) Aargau (AG) — The heaviest concentration of sector anchors: Soudronic in Bergdietikon for can body welding, Oerlikon Metco in Wohlen for thermal spray and laser cladding, Messer Schweiz in Lenzburg for industrial and welding gases. (3) Eastern Switzerland (SG, TG) — Qualification-heavy processes and the fabrication base that supports them. (4) Mittelland and Northwestern Switzerland (BE, SO, BL, AG) — The long tail made visible. Alexander Binzel runs its Swiss branch from Grenchen, Aare Schweisstechnik operates in Wangen an der Aare, AARWELD in Mägenwil, Ferroweld in Thun. Regional concentration affects valuations, as companies in established clusters benefit from supplier ecosystems, specialized talent pools, and industry networks.
