What Zwahlen & Mayr does
Zwahlen et Mayr S.A. (Zwahlen & Mayr) is a Swiss specialty industrial manufacturer founded in 1881 and headquartered at Route de l'Industrie 18 in Aigle, Canton of Vaud. The company produces stainless steel welded and welded-redrawn precision tubes and operates two product divisions — ZM Tubes (tube manufacturing) and ZM Steel Construction (steel construction services) — both serviced from a single integrated site in Aigle. Its core business is B2B supply of certified stainless steel precision tubes to industrial buyers, complemented by steel-construction services; the source material does not disclose pricing models, named customers, customer segments, or distribution channels, so the commercial mechanics are largely inferred from the company's public-company status, its dividend-payment calendar, and its long-running annual/biannual reporting cadence dating back to at least 2007.
The company's capital structure is that of a small Swiss public limited company: share capital of CHF 14,040,000, listed on SIX Swiss Exchange under ISIN CH0002661731, with 101–250 employees and an IDE/UID of CHE-108.107.754. Operating geographies disclosed are limited to Switzerland. Zwahlen & Mayr has historically distributed annual dividends (with ex-dividend, record, and payment dates published each spring) and published annual and biannual financial reports on its investor-relations website.
The company's recent history is dominated by ownership transition and governance events rather than organic expansion. Key changes include a 2020 CEO and General Director change, an August 2024 CFO resignation, December 2024 announcement of negotiations with Group Bader SA, a March 2025 sale-and-purchase agreement execution, April 2025 transaction closing with concurrent board resignations, a September 2025 public takeover offer by Group Bader SA, a May 2025 ad hoc fraud announcement, and a June 2026 delisting announcement. Earlier in its history, Zwahlen & Mayr divested Sitindustrie Suisse SA in March 2012. As of the latest source material, the entity is undergoing delisting and integration into the Bader group; the zwahlen.ch site now carries a Groupe Bader banner, signaling that post-acquisition positioning is being directed by the new parent.

- Outokumpu: Finland-based global leader in stainless steel, including production of stainless tube feedstock; comparable as a stainless steel supplier to ZM Tubes and adjacent in the precision-tube value chain.
- ThyssenKrupp Steel Europe: Major European flat steel and tubular products producer with extensive stainless and specialty steel offerings; broader and larger than Zwahlen & Mayr but operates in adjacent stainless tube markets.
