The FDA accepts the NDA for reboxetine (oral NRI) in NT1 narcolepsy patients

with cataplexy, assigning a May 1, 2027 PDUFA. We are 70-80% confident in an PRICE TARGET | % TO PT $380.00 | +62%

Auvelity (oral NMDA) by assuming $6B+ in peak sales for MDD and Alz agitation MARKET CAP $12.0B

noted.

Big picture: AXSM is launching 3 CNS/neuro products, including Auvelity (oral NMDA) in MDD

depression and Alz agitation (AADAD). For Auvelity, both mgmt's recently revised peak sales

guidance of $8B (split evenly between MDD/AADAD) could imply significant upside potential if

we were to assume a 3-4x multiple (Auvelity has a long IP tail), making AXSM's CNS pipeline

spanning 10+ indications mostly 'call options'. As Auvelity's sales potentially accelerate during

2026-27, AXSM could add another commercial product with AXS-12 (reboxetine, oral NRI) for NT1

narcolepsy patients with cataplexy. Ultimately, we expect AXSM to turn profitable by 2027, thereby

attracting Big Pharma interest.

The FDA has accepted reboxetine's NDA for the treatment of cataplexy (muscle weakness) in

narcolepsy patients, assigning a May 1, 2027 PDUFA on a 12-month standard review (from

submission).
