ADC Therapeutics Cuts Change-of-Control Fee on ZYNLONTA Deal in New Royalty Agreement, Lowers Potential Payout to $150M Through 2027

ADC Therapeutics SA (NYSE:ADCT), a commercial-stage global leader and pioneer in the field of antibody drug conjugates (ADCs), today announced that it has entered into an amendment to its royalty purchase agreement with entities managed by HealthCare Royalty.

 

Based on confidence in the long-term outlook for ZYNLONTA®, ADC Therapeutics negotiated mutually beneficial updated terms with HealthCare Royalty, offering greater strategic flexibility to the Company. The new agreement reduces the change of control payment from $750 million to $150 million through the end of 2027, and to $200 million thereafter. In the event of a change of control, HealthCare Royalty will continue to receive royalties on sales by the acquirer until the original royalty cap is reached. In return, HealthCare Royalty has been granted warrants to purchase approximately 9.8 million common shares, with an exercise price of $3.81 per share. These warrants are exercisable until December 31, 2030, and are subject to a lock-up through the end of 2027.
