SIPAREX takes majority stake in CLAYENS GROUP

The acquisition of a majority stake in Clayens Group by One Equity Partners marks the exit of the previous majority shareholder, Siparex, which alongside existing co-investors and the incumbent management team led by CEO Eric Pisani, will reinvest as minority partners to maintain corporate continuity. Under Siparex’s stewardship since 2019, the group scaled its operations from €273 million to over €350 million in trailing twelve-month revenue, primarily driven by the execution of four strategic add-on acquisitions that expanded its geographic and technological footprint. The transition of ownership to One Equity Partners is timed to capitalize on macro-driven industrial re-shoring trends, as multinational OEMs shift production volumes from China back to European and North American manufacturing hubs amid increasing supply chain constraints. Moving forward, the post-acquisition operational agenda focuses on accelerating Clayens' transition from a regional European champion into a global outsourced manufacturing platform by leveraging One Equity Partners' capital and pipeline in North America to execute cross-Atlantic transformational combinations. The immediate growth strategy prioritizes scaling existing facilities in North America and Eastern Europe, increasing utilization across the 25 operational sites, and pursuing target acquisitions to broaden specialized technical capabilities in high-margin sectors such as medical and aerospace components.

This operation represents the first programmatic bolt-on acquisition executed by Clayens NP since its primary sponsor-backed buyout, designed to accelerate the platform’s diversification into highly resilient and high-margin healthcare manufacturing verticals. Negotiated on a proprietary bilateral basis due to long-standing industrial relationships and a previous site acquisition in 2017, the transaction allows the seller, PSB Industries, to complete its strategic pivot toward luxury and beauty packaging while divesting a non-core industrial asset. The acquisition adds >€50 million in revenue to Clayens NP, driving consolidated group sales toward €350 million and establishing an essential manufacturing bridgehead in Mexico to serve the North American nearshoring market. The transaction funding mechanism leverages a combination of available balance sheet cash and a structured share swap, resulting in PSB Industries taking a minor equity position within the Clayens holding structure alongside the existing sponsor pool and management. This structural alignment facilitates management continuity, ensures operational stability across the five acquired sites, and underpins the strategic cross-selling of polymer and cleanroom manufacturing capabilities to the combined global customer base.
