Pharmaceutical behemoth Eli Lilly acquired AtaiBeckley in a purchase worth up to $3.8 billion today, sending the latter’s shares 34% higher. The deal consists of $6.75 in cash per ATAI share, as well as $2.50 in contingent value rights (CVRs) tied to two of AtaiBeckley’s treatments meeting certain milestones over the next four, five, and seven years.
Thanks to the value of these CVRs, ATAI’s $7.15 share price currently sits above the $6.75 cash portion of the deal, suggesting the market sees potential in AtaiBeckley’s psychedelic treatments reaching their various milestones. AtaiBeckley offers DMT and other psychedelic treatments for depression, anxiety, and opioid use disorder, and has seen its stock double over the last year thanks to today’s deal and the Trump administration’s positive outlook on psychedelic-based treatments.
