Item 4 Ownership

The following information with respect to the ownership of common shares of the Issuer by the Reporting Persons filing this statement on Schedule 13G is provided as of December 31, 2018.

Reporting Persons — dievini Hopp BioTech holding GmbH & Co. KG (2)	18,041,000	18,041,000	18,041,000	25.1 %
DH-Capital GmbH & Co. KG (3)	18,041,000	18,041,000	18,041,000	25.1 %
OH Beteiligungen GmbH & Co. KG (3)	18,041,000	18,041,000	18,041,000	25.1 %
Dietmar Hopp (3)(4)	18,041,000	18,041,000	18,041,000	25.1 %
Oliver Hopp (3)	18,041,000	18,041,000	18,041,000	25.1 %
Daniel Hopp (3)	18,041,000	18,041,000	18,041,000	25.1 %
Prof. Dr. Friedrich von Bohlen und Halbach (3)(4)	18,041,000	18,041,000	18,041,000	25.1 %
Prof. Dr. Christof Hettich (3)(4)	18,041,000	18,041,000	18,041,000	25.1 %
Dr. Mathias Hothum (4)	18,041,000	18,041,000	18,041,000	25.1 %

(1) This percentage is calculated based on 71,741,285 shares of the Issuer’s common shares reported to be issued by the Issuer in its Registration Statement on Form F-3 filed with the Securities and Exchange Commission on October 23, 2020.

(2) 18,041,000 common shares of the Issuer are held of record by dievini.

(3) DH-Capital, OH Beteiligungen, Dr. von Bohlen and Dr. Hettich are collectively the holders of 100% of the limited partner interest in dievini. DH-Capital and OH Beteiligungen each hold a 40% limited partner interest in dievini and therefore, control the voting and dispositive decisions of dievini together and may be deemed to beneficially own the shares held by dievini. Dietmar Hopp, Oliver Hopp and Daniel Hopp are the ultimate controlling persons of dievini, DH-Capital and OH Beteiligungen, and control the voting and investment decisions of the ultimate parent company of dievini and therefore, may be deemed to beneficially own the shares held by dievini by virtue of their status as controlling persons of dievini.

(4) The sole general partner of dievini with the authorization to represent is dievini Verwaltungs GmbH; however, 100% of the shares of dievini Verwaltungs GmbH are held by dievini so dievini Verwaltungs GmbH is not considered to have control over dievini. The managing directors of dievini Verwaltungs GmbH are Dietmar Hopp, Dr. von Bohlen, Dr. Hettich and Dr. Hothum. Voting and dispositive decisions made within dievini Verwaltungs GmbH regarding the securities held by dievini are made by at least two managing directors acting together; however, Dietmar Hopp is entitled to represent dievini Verwaltungs GmbH solely. Therefore, in their capacity as managing directors, Dietmar Hopp, Dr. von Bohlen, Dr. Hettich and Dr. Hothum share voting and dispositive power over the shares held by dievini, and may be deemed to beneficially own such shares held by dievini; however, each of Dietmar Hopp, Dr. von Bohlen, Dr. Hettich and Dr. Hothum disclaims beneficial ownership of the shares held by dievini except to the extent of their pecuniary interests therein.
