Allen & Overy advises Elmos Semiconductor SE on sale of Dortmund wafer fab to Littelfuse

Allen & Overy has advised Elmos Semiconductor SE (Elmos), one of the leading suppliers of mixed-signal automotive semiconductors, on the sale of its wafer* fabrication operations (fab) to Littelfuse, Inc., USA (Littelfuse). Elmos has agreed to sell the fab at a net purchase price of approximately EUR 93 million. Under the agreement, Littelfuse will acquire the Dortmund wafer fab with approximately 225 employees. All other activities, including test operations, will remain with Elmos.

In acquiring the Dortmund wafer fab, Littelfuse enhances its capabilities in power semiconductors for high-growth power conversion applications like renewables, energy storage, and e-mobility charging infrastructure.

The closing of the transaction is expected to be effective 31 December 2024, and is subject to certain closing conditions and regulatory approvals. 

In addition, Elmos and Littelfuse have agreed to enter into a defined multi-year capacity sharing arrangement with an initial term lasting through 2029, with Elmos buying defined volumes of wafers produced at the fab. This long-term agreement supplements the existing supply arrangements with Elmos' other foundry partners and ensures that Elmos has the necessary capacities to meet projected customer demand.

Elmos develops, produces and markets semiconductors, primarily for use in the automotive industry. The company's components communicate, measure, regulate and control safety, comfort, powertrain and network functions. For 40 years, Elmos' innovations have been bringing new functions to life, including solutions in applications such as ultrasonic distance measurement, ambient and rear light as well as intuitive HMI.

Littelfuse is a diversified industrial technology manufacturing company empowering a sustainable, connected and safer world. The company operates across more than 20 countries, and with approximately 18,000 global associates. In Germany, Littelfuse operates various manufacturing, sales and R&D sites.
