Business Commentary:

• Strong Financial Performance:
• Vertex Pharmaceuticals reported revenue of $3080 million for Q3, reflecting double-digit year-over-year growth compared to Q3 2024.

• The growth was driven by the ongoing launch of new products like ElefTrak, KASJEVY, and GERNAVIX, as well as increased patient demand for existing CF therapies and expanding global momentum for these new products.

• Pipeline and Product Development:

• Vertex's CF pipeline is advancing with promising results in clinical trials. ElefTrak, launched in the U.S. and Europe, saw strong patient response and marked improvements in sweat chloride levels.

• The company's renal disease portfolio, particularly PoV for IGAN, is advancing rapidly with full enrollment in the Phase III trial, setting the stage for potential accelerated approval in the U.S. by the end of the year.

• Commercial Success and Access:

• The launch of GERNAVIX has seen a positive response, with over 170,000,000 lives covered by reimbursed access, doubling prescription volumes from Q2 to Q3, and achieving significant reductions in opioid use.

• The company is building a commercialization team for its renal franchise, with PoV in IGAN being a key focus, aiming to become a significant growth driver in the future.

• R&D Investment and Financial Guidance:

• Non-GAAP R&D expenses increased to $1,280 million in Q3 2025, up from $1,080 million in Q2 2024, driven by the advancement of the broad pipeline, including the acceleration of PoV development programs.
• Vertex's full-year 2025 revenue guidance was updated to a range of $11,900 million to $12,000 million, reflecting continued growth from its CF medicines and potential contributions from new products like GERNAVIX.

Sentiment Analysis:

Overall Tone: Positive

• Management repeatedly described Q3 as a strong quarter: '$3,080,000,000 in revenue reflecting double digit growth versus Q3 2024' and 'double digit revenue growth.' Pipeline and commercial milestones highlighted: full enrollment for RAINIER (≈600 pts), strong launches for ElefTrek, KASJEVY and GERNAVIX, and upwardly revised guidance items, supporting a positive tone.

Q&A:

• Question from Jeff Meacham (Citibank): Update on ElefTrek adoption (tipping point/monitoring) and high‑level differentiation of PoV vs other BAFF/APRIL agents?
  Response: ElefTrek: the vast majority of newly eligible U.S. patients have initiated treatment and transitions from Trikafta are steady; PoV: dual BAFF/APRIL inhibition with engineered tissue penetration and monthly low‑volume auto‑injector yields promising early data and differentiates the asset.

• Question from Talveen Richter (Goldman Sachs): How should we think about PoV readthrough to eGFR and status of the third PBM for Genavix?
  Response: Reductions in proteinuria (and hematuria/GDIGA1) are expected to translate into eGFR stabilization over time; commercial: productive conversations with the third PBM are ongoing and patient support covers gaps while access expands.

• Question from Jessica Fye (JPMorgan): Current capital allocation priorities and preferred BD stage?
  Response: Top priority is reinvesting in internal/external innovation (R&D and commercialization); secondary is share repurchases; BD targets deals that fit the strategic 'SandBox' irrespective of development stage.

• Question from Evan Seigerman (BMO Capital): How important is PoV's auto‑injector/once‑monthly/low‑volume profile versus competitors?
  Response: Monthly, low‑volume at‑home auto‑injector is a major commercial and adherence differentiator and, together with mechanism and clinical profile, supports PoV's best‑in‑class potential.

• Question from Tazeen Ahmad (Bank of America): What did the FDA review that supported Breakthrough designation and rolling submission for PoV?
  Response: After a pre‑BLA meeting where the agency reviewed available data and the planned CTV/filing approach, FDA endorsed rolling submission and granted Breakthrough designation based on unmet need and the therapy's profile.

• Question from Terence Flynn (Morgan Stanley): Any update on the No Pain Act and will Phase IV data include time‑to‑discharge metrics?
  Response: No Pain Act final list was delayed by the government shutdown and advocacy continues; Phase IV aesthetic/reconstructive data (this week) shows substantial opioid reductions—time‑to‑discharge endpoints are part of other studies but not yet reported.

• Question from Edward (for David Reisinger) (Leerink Partners): Of the 170M lives for Genavix, how many are unrestricted and update on VX‑828 timeline/data?
  Response: Of 170M covered lives, 113M are unrestricted (no prior auth/step edits); VX‑828 is the most efficacious corrector in vitro we've tested, CF cohort initiated and clinical data expected next year.

• Question from Phil Nadeau (TD Cowen): Current gross‑to‑net dynamics for Genavix and when can you formalize a multi‑year transition rate from Trikafta to ElefTrek?
  Response: Gross‑to‑net is elevated in 2025 mainly due to the active patient support program; management expects the majority of Trikafta patients to transition to ElefTrek over the coming years but will not provide a formal multi‑year transition percentage yet.

• Question from Julian (for Paul Matteis) (Stifel): Any update on Suzetra‑gene (chronic pain) development or acquisition plans to expand pain portfolio?
  Response: No new updates on broader chronic pain; primary focus is completing two DPN Phase III studies (second starting soon) to secure the DPN indication, with broader TNP strategies and combination approaches under evaluation.

• Question from Gena Wang (Barclays): Given VERA's eGFR bar, could PoV actually improve eGFR with longer treatment?
  Response: Management is pleased with upcoming ASN data and expects reductions in proteinuria/hematuria to translate into eGFR stabilization; eGFR data from the PoV IGAN program will be presented.

• Question from Mohit Bansal (Wells Fargo): Would Vertex pursue much larger BD transactions ($5–10B) or remain focused on smaller deals?
  Response: BD is driven by strategic fit with R&D (SandBox) rather than deal size; Vertex remains open to small or large transactions if aligned with the strategy and therapeutic focus.

• Question from Jake (for Myles Minter) (William Blair): Update on DM1 program timeline and how KASJEVY adverse events are disclosed during the patient journey?
  Response: DM1: SAD completed, MAD ongoing with results expected next year; adverse events from clinical‑trial patients are reported via trial reporting systems, and commercially treated patients' events are reported through standard physician/company/FDA channels.

• Question from William Pickering (Bernstein): Competitive landscape and addressable market for PoV in primary membranous nephropathy (PMN)?
  Response: Membranous and IgAN are both B‑cell/autoantibody mediated but membranous is a smaller Western market (~150k) with less competitive intensity; PoV is among the leading APRIL/BAFF programs and is already in Phase 2/3 (OLYMPUS) for PMN.
