One Equity Partners (OEP) is to acquire Clayens NP (Clayens), a value-added outsourced contract manufacturer of high-performance polymers, composites and precision metals from a group of investors led by French private equity firm Siparex.

As part of the transaction Siparex, its co-investors, as well as management team, will reinvest in the business alongside middle market private equity firm OEP to continue supporting the company as minority partners.

Led by its CEO Eric Pisani and with the active backing of Siparex since 2019 Clayens has implemented a sustained growth strategy, including four significant acquisitions, which helped Clayens record strong growth in turnover from €273 million in 2019 to over €350 million in the last twelve months.
