(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 and Oliver 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.

(5)

Daniel Hopp is managing director of the general partner of DH-Capital with the sole power of representation and therefore he is entitled to make voting and dispositive decisions solely. Therefore, by virtue of his position, Daniel Hopp may be deemed to beneficially own such shares held by dievini; however, Daniel Hopp disclaims beneficial ownership of the shares held by dievini except to the extent of his pecuniary interests therein.

(6)

Represents shares held through personal accounts, of which the holder has sole voting and dispositive power.

(7)

(8)

This percentage is calculated based on (i) 56,296,042 shares of the Issuer’s common shares reported to be issued and outstanding immediately after the consummation of the Issuer’s initial public offering (including shares issued in connection with the underwriters’ overallotment option to purchase up to 900,000 additional common shares in connection with the Issuer’s initial public offering), as reported by the Issuer in its final prospectus for its initial public offering dated as of September 22, 2016 as filed with the Securities and Exchange Commission on September 23, 2016 pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended and (ii) assumes the 14,750 common shares underlying the options to purchase common shares held by Dr. Hothum are deemed outstanding pursuant to Rule 13d-3(d)(1)(i).
