EQS-Adhoc: Elmos Semiconductor SE: Agreement signed on the sale of the Elmos wafer fab in Dortmund to Littelfuse

Public disclosure of inside information pursuant to Article 17 Market Abuse Regulation (MAR)

Elmos Semiconductor SE (FSE: ELG, “Elmos”), one of the world’s leading suppliers of mixed-signal automotive semiconductors, and Littelfuse, Inc., USA (NASDAQ: LFUS, “Littelfuse”), a diversified, industrial technology manufacturing company, today entered into a definitive agreement on the sale of the Elmos wafer fab (“fab”) at the Dortmund site to Littelfuse. Under the agreement, a German subsidiary of Littelfuse will acquire the Elmos wafer fab at the Dortmund site with approximately 225 employees. All other activities, including testing operations, will remain with Elmos.

Elmos has agreed to sell the Dortmund wafer fab at a net purchase price of approximately 93 million Euro. Following regulatory approvals, the buyer will make a payment of approximately 37 million Euro. The remaining approximately 56 million Euro will be paid at closing, expected to be effective December 31, 2024. With the acquisition of the Dortmund fab, Littelfuse enhances its capabilities in power semiconductors.

The closing of the transaction is subject to certain closing conditions and regulatory approvals, among them the investment control procedure under foreign trade law conducted by the German Federal Ministry of Economic Affairs and Climate Action. The closing of the transaction is expected to be effective December 31, 2024. Elmos will retain full operational control over the wafer fab until the closing date.

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.

The transaction has no major effects on EBIT in fiscal year 2023, which is why the current forecast for the full-year EBIT margin in 2023 (25% ± 2 percentage points) continues to apply. Cash flow is expected to be positively influenced in fiscal year 2023 by the payment of approximately 37 million Euro after regulatory approvals. Irrespective of the transaction, Elmos continues to increase its efforts to expand testing capacities for future growth. The company now anticipates capital expenditures of approximately 19% ± 2 percentage points of sales in fiscal year 2023 (previously: 17% ± 2 percentage points). As a result, Elmos now expects a negative operating adjusted free cash flow in 2023.
