The bearer shares of Biotest GmbH & Co. KGaA (ISIN DE0005227201 und DE0005227235) will be converted on

18 May 2026

into registered shares of Biotest GmbH & Co. KGaA (ISIN DE000A41YE56 und DE000A41YE49) and included in CASCADE-RS.

Creation of holdings in registered shares

The creation of registered share positions on the relevant conversion date will be carried out by Clearstream Europe AG¹ in the standard processing on 15 May 2026 with value date 18 May 2026 on the custody account balances and positions of pending stock exchange trades.

The positions in the registered shares of Biotest GmbH & Co. KGaA are created in unregistered positions (Freier Meldebestand - FMB). Instructions in CASCADE-RS will be possible from 18 May 2026.

Stock exchange trades and securities transfers in the registered shares of Biotest GmbH & Co. KGaA will be first processed on 18 May 2026.

Pending instructions

Security transfers against payment that are entered in CASCADE and are pending for settlement will be converted. Security transfers free of payment that are flagged with match status "J" are converted as well.

Note: To ensure smooth settlement processing, clients must avoid a manual conversion, especially matched against payment instructions. CEU will convert securities transfers against payment into the ISIN of the registered shares automatically in the standard processing of 15 May 2026. Modifications and cancellations of instructions in the ISIN of  bearer shares are possible at any time until the automatic conversion. It is recommended that instructions in the ISIN of the registered shares are not entered before 18 May 2026.

Unmatched securities transfers free of payment that are stored in CASCADE will automatically be deleted by T2S after 20 business days and must be re-entered by the participants into registered shares, if required.

Registration of shareholders in the share register

The registration of the shareholders in the share register of the issuer is implemented via the depository banks by re-registration in CASCADE-RS using the re-registration type "2" ("other not from purchase"). Information about the notification of the shareholders in the share register can be taken from the "Guidelines for banks on entering shareholder data in CASCADE-RS" (Announcement RS137).

Share register

The share register is managed by Computershare Deutschland GmbH & Co. KG.

Note about submission planning

Due to the processing capacities in CASCADE-RS, submissions amounting to 10,000 re-registrations or more per transfer must be arranged in advance with Client Services. Within the scope of overall coordination, CEU reserves the right to reject file transfers that have not been arranged in advance.

Reimbursement

For re-registrations that are transmitted between 18 May 2026 and 22 May 2026, CEU charges a discounted price of EUR 0.30 per position. After this time period, CEU clients will be reimbursed accordingly.
