colleen.garvey@guggenheimpartners.com 1) We are tracking new product launches, such as:

(pg. 128) TRx for WE 5/15/26 were 926 vs. 925 the week prior. 617 859 4664 • NOVN-SWX's Rhapsido

Zach Dunn, Ph.D. Rhapsido was approved for CSU on Sep. 30, 2025, and the first reported IQVIA TRx

zach.dunn@guggenheimpartners.com was captured on 10/17/25. Mgmt has stated multibillion-dollar peak sales potential for 617 859 4603 Rhapsido in CSU alone.

Within pain, VRTX's JOURNAVX (pg. 128) is over one year into launch following approval •

on January 30, 2025. For WE 5/15/26, TRx were 20,380 vs. 19,640 the week prior

(+4% WoW). We expect JOURNAVX to be widely reimbursed, and VRTX had expected

broad payer access by YE25. As of 1Q26 earnings, all ~300 sales reps are now in the

field, setting VRTX well on track toward their goal of >3x prescriptions in 2026 vs. 2025.

Management simultaneously continues to advance access, exemplified by (1) ~240M

covered lives with reimbursed access (up from ~200M in 4Q25), (2) coverage with 1/4

large Medicare Part D plans, with coverage in a second plan to be initiated by July 1. As
