PARIS, October 13, 2025 – Proskauer advised the management team of the Caillau Group (“Caillau”), a global specialist in metal fastening solutions for the automotive industry and other critical industrial applications, on the sale of the company to Montyon Capital, an independent investment platform focused on high-potential businesses across Europe.
This transaction marks the exit of the company’s historical investors, led by Cathay Capital, and opens a new chapter of growth for Caillau.
Founded in 1919 and based in Romorantin-Lanthenay, Caillau designs, develops, and manufactures high-performance fastening systems (including clamps, quick connectors, and V-band clamps) for major global automotive manufacturers as well as for industrial and aerospace applications. Renowned for the reliability and technical sophistication of its products, Caillau has established itself as a strategic partner to leading international OEMs and tier-one suppliers, with annual revenues exceeding €150 million.
In recent years, under the leadership of Cathay Capital and the management team headed by Stéphane Drivon, Caillau has strengthened its position as a technological leader in the automotive sector by developing solutions tailored to vehicle electrification and new environmental standards. The company has also expanded into adjacent high-value sectors such as aerospace, defense and solar energy, and has implemented an ambitious innovation strategy supported by its globally recognized in-house R&D.
Montyon Capital’s investment marks the beginning of a new phase of growth for Caillau, focused on continued international expansion and further diversification into new adjacent sectors.
The Proskauer team was led by partner Xavier Norlain and included counsel Aymeric Robine and associate Mohamed Kettani (M&A/Private Equity). The team also included partner Gwenaël Kropfinger and associate Maxime Dussartre (Tax).
