ADC Therapeutics cuts change-of-control payment to HCR from $750M to $150-200M; issues warrants
--------------------------------------------------------------------------------

- Under amended HCR agreement, change-of-control payment reduced to $150M before 2028 or $200M after, from $750M previously.
- Post-change-of-control royalties continue unless bought out for $525M-$750M less payments already made.
- ADC issued warrants to HCR for 9,834,776 common shares at $3.8130 per share, exercisable until Dec 31, 2030.
- Warrants are non-transferable before Jan 1, 2028; registration statement to be filed within 30 business days.
- HCR had already provided $300M under original 2021 agreement; amendment reduces ADC's near-term buyout risk.
