DGAP-Adhoc: Biotest AG: Reduction of guidance

Ad-hoc RELEASE
Announcement according to Article 17 European Market Abuse Regulation (MAR)

Dreieich, 08 Dezember 2021. Due to the changing market environment for the plasmatic coagulation factor VIII, the Supervisory Board of Biotest Aktiengesellschaft decided in its meeting today that Biotest will only produce factor VIII in a sales-correlated manner in the future. Biotest will therefore make depreciations on existing raw material in the amount of approximately € 38 - 45 million.

The exact financial impact of the one-time effect is currently still being determined. As a precautionary measure, Biotest AG is reducing its EBIT guidance for 2021 from € - 5 to - 10 million to approximately € - 43 to - 55 million.
