Potential for development
In 2021, Sero could complete the acquisition of Semecs, a Dutch EMS provider focused on medium-volume, mid-mix industrial and medical applications. The transaction broadens Sero's customer base and increases manufacturing flexibility through an additional site in Slovakia. In this context, management expects synergy potential in the form of savings in production costs through the optimal allocation of projects to the respective sites and additional revenues through a broader, complementary service offering.
The acquisition of Syncron EMS, a US-based EMS provider, was completed in 2022 to drive the further internationalization of the Group. The transaction gives Sero access to the attractive NAFTA region, where both existing and new customers can be served.
