Explanation of Responses:

1. Thomas Pfisterer holds a portion of the shares directly and the other portion indirectly via HPWH TH AG ("HPWH") and HPWH MH AG ("MH"). The principal business of HPWH is holding investment rights in, directly or indirectly, ADC Therapeutics. HP WILD Holding AG ("HPW Holding") is an intermediary holding company. Thomas Pfisterer is a board member of HPWH. By reason of a stockholders' agreement by and among Mr. Pfisterer and HPW Holding and their joint indirect minority equity interest in HPWH via their joint ownership of MH, which owns a 12.5% interest in HPWH, Mr. Pfisterer may be deemed to have shared voting and investment power with respect to such shares held of record by HPWH. However, Mr. Pfisterer disclaims beneficial ownership of all common shares held of record by HPWH other than the shares indirectly represented by his 41.7% interest in MH.
