“With the closure of this transaction, we are further sharpening our portfolio focus on technology-driven business,” said Belén Garijo, chair of the executive board and CEO of Merck. “Alongside the recent acquisitions of SpringWorks Therapeutics, HUB Organoids, Unity-SC, and Mirus Bio, the divestiture of non-strategic business remains a key component of our M&A strategy, geared toward ensuring long-term growth through innovation.”
“We are delighted to welcome the new employees to our company. Our activities complement one another to a large extent in terms of products, expertise and regional presence. Together, we are on an excellent footing to drive growth in a highly dynamic market segment,” said Ertian Su, chairman & chief executive officer of GNMI.
The transaction covers Merck’s global Surface Solutions business with sales of more than €400 million in 2024, which GNMI will continue under the new Susonity brand. Around 1,100 employees, more than 600 of whom are based in Germany, have been transferred to GNMI. As part of the agreement with Merck, GNMI has guaranteed both the future of the Gernsheim site and the employment of its staff based in Germany until 2032. Savannah, USA, and Onahama, Japan, will remain important production sites for Susonity alongside Gernsheim. Moreover, Merck and GNMI have entered into a series of supply and service agreements to ensure the seamless transition of the business.
Merck will remain the owner of the property at the Gernsheim site. The area used by Surface Solutions will be leased to GNMI on a long-term contract. The GreenTech-Park Fluxum in Gernsheim is not affected by the divestment.
