• On 12 May 2026, the Management Board of the Company resolved to enter into a lease agreement with Carl Zeiss AG for the future headquarters at the Jena site ("Jena high-tech site") based on the following key terms and conditions: The base rent amounts to €8.8m per year and shall be paid by the Company starting from the 2027/28 fiscal year.

On this basis, the lease agreement is now to be finalized and concluded shortly thereafter.
• Furthermore, on 12 May 2026, Carl Zeiss Meditec AG and Carl Zeiss AG reached an agreement regarding an increase in costs for passing on additional costs for services provided within the Group. These include, in particular, IT, HR and other shared services, for which the ZEISS Group has incurred considerable additional expenses in recent years due to wage inflation and increased infrastructure costs. The total annual expense charged to the Company for these services will increase in three steps by a total of approximately EUR 30 million starting in the current 2025/26 fiscal year and continuing through the 2028/29 fiscal year.

The aforementioned agreements constitute transactions with related parties within the meaning of section 111a et seq. of the German Stock Corporation Act (AktG). Carl Zeiss AG, based in Oberkochen, as the parent company, holds the majority of voting rights in Carl Zeiss Meditec AG and therefore constitutes a related party within the meaning of Section 111a (1) Sentence 2 of the German Stock Corporation Act (AktG).

The Supervisory Board of Carl Zeiss Meditec AG approved the aforementioned transactions in accordance with Section 111b (1) German Stock Corporation Act (AktG) on 8 May 2026 and authorized the Management Board to conclude the corresponding transactions.
