Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today reported consolidated financial results for the fourth quarter and full year ended December 31, 2025, and provided its full year 2026 financial guidance.

“2025 marked a year of strong revenue growth, commercial diversification, and pipeline advancement,” said Reshma Kewalramani, M.D., Chief Executive Officer and President of Vertex. “Our focus in 2026 remains on executing across the CF franchise, bringing CASGEVY to more patients around the globe and continuing to launch JOURNAVX, as we also prepare for the anticipated near‑term commercialization of povetacicept in IgAN. With expanding leadership in CF, exciting commercial momentum, and multiple mid- and late-stage programs advancing, Vertex is well positioned to deliver long‑term value for patients and shareholders.”

Fourth Quarter 2025 Results

Total revenue increased 10% to $3.19 billion compared to the fourth quarter of 2024, primarily driven by the continued performance of cystic fibrosis (CF) therapies and additional growth from diversification into additional disease areas. In the U.S., total revenue increased 12% to $2.06 billion due to continued strong CF patient demand, including for ALYFTREK; a modest benefit from CF channel inventory; higher realized net prices in CF versus the prior year; and contributions from CASGEVY and JOURNAVX. Outside the U.S., total revenue increased 5% to $1.13 billion due to solid CF performance across multiple geographies and increased CASGEVY revenue.

Combined GAAP and non-GAAP R&D, Acquired IPR&D and SG&A expenses were $1.52 billion and $1.36 billion, respectively, in the fourth quarter of 2025, compared to $1.46 billion and $1.30 billion, respectively, for the fourth quarter of 2024. These increases were primarily due to commercial investment to support the launch of JOURNAVX in acute pain.

GAAP and non-GAAP effective tax rates were 10.5% and 13.5%, respectively, compared to 19.7% and 21.3%, respectively, for the fourth quarter of 2024. In the fourth quarter of 2025, the tax rates incorporated a one-time benefit from recognition of previously deferred tax credits and a change in estimated prior-year liabilities.

GAAP and non-GAAP net income were $1.2 billion and $1.3 billion, respectively, compared to $913 million and $1.0 billion, respectively, for the fourth quarter of 2024, primarily driven by increased product revenue.

Full Year 2025 Results

Total revenue of $12.0 billion increased 9% compared to 2024, primarily driven by the continued performance of CF therapies and early contributions from the three ongoing launches. In the U.S., total revenue increased 13% to $7.55 billion due to continued strong CF patient demand, including for ALYFTREK, and higher realized net prices in CF versus the prior year; as well as contributions from CASGEVY and JOURNAVX. Outside the U.S., total revenue increased 3% to $4.45 billion due to solid CF performance across multiple geographies and contributions from CASGEVY.

Combined GAAP and non-GAAP R&D, Acquired IPR&D and SG&A expenses were $5.8 billion and $5.1 billion, respectively, compared to $9.7 billion and $8.8 billion, respectively, in 2024. The decreases were primarily due to $4.4 billion of AIPR&D expenses associated with Vertex’s acquisition of Alpine Immune Sciences incurred in the second quarter of 2024, partially offset by increased R&D investment in support of multiple mid- and late-stage clinical development programs and increased commercial investment to support the launch of JOURNAVX.

GAAP and non-GAAP effective tax rates were 14.9% and 17.3%, respectively, compared to 315.5% and 91.0%, respectively, in 2024. In 2025, the effective tax rates were lower than U.S. statutory rates primarily due to one-time benefits from recognition of previously deferred tax credits and Alpine-related R&D tax credits. The GAAP effective tax rate also included excess tax benefits related to stock-based compensation.

GAAP and Non-GAAP net income were $4.0 billion and $4.7 billion, respectively, compared to a GAAP net loss of $(536) million and non-GAAP net income of $111 million, respectively, for 2024, reflecting the Alpine AIPR&D in 2024 and increased product revenue partially offset by increased operating expenses.

Cash, cash equivalents, and total marketable securities as of December 31, 2025, were $12.3 billion, compared to $11.2 billion as of December 31, 2024. The increase was primarily due to cash flows from operating activities, partially offset by repurchases of Vertex’s common stock pursuant to its share repurchase programs.

Full Year 2026 Financial Guidance

Vertex today provided full year 2026 financial guidance. Vertex’s total revenue guidance of $12.95 billion to $13.1 billion includes expectations for continued growth in CF, including the ongoing U.S. rollout and ex-U.S. launches of ALYFTREK; as well as $500 million or more in revenue from non-CF products, including increased patient infusions of CASGEVY through Vertex’s global ATC network and growth in prescriptions and revenue from the second year of the launch of JOURNAVX. Vertex’s guidance for both combined GAAP and non-GAAP R&D, AIPR&D and SG&A expenses includes expectations for continued investment in multiple mid- and late-stage clinical development programs and commercial and manufacturing capabilities, and approximately $100 million of currently anticipated AIPR&D expenses. This guidance also includes an immaterial cost impact from tariffs in 2026 based on currently known tariff rates and regulations.

Vertex’s financial guidance is summarized below:

Key Business Highlights

Marketed Products

Cystic Fibrosis (CF) Portfolio

Vertex has worked for more than 20 years to discover and develop medicines to treat the underlying cause of CF. Vertex CFTR modulators can treat nearly 95 percent of all people living with CF in core markets and are approved for patients as young as one month old. ALYFTREK, the newest marketed CFTR modulator, is approved in the U.S., the United Kingdom (U.K.), the European Union (EU), Canada, New Zealand, Switzerland, Australia, and Israel for the treatment of patients 6 years and older. Vertex anticipates that the number of CF patients taking its medicines will continue to grow through new approvals and reimbursement agreements, treatment of younger patients, increased survival, and expansion into additional geographies. Recent progress includes:

• ALYFTREK is reimbursed for eligible patients in the U.S., England, Ireland, Germany, Denmark, Northern Ireland, Norway, Wales, Italy, Australia, New Zealand, and Luxembourg. Vertex is working to secure access for eligible patients in additional countries.
• In January, Vertex completed the pivotal study of ALYFTREK in children 2 to 5 years of age. The data showed that ALYFTREK was generally safe and well tolerated, consistent with the established safety profile. Treatment with ALYFTREK resulted in a clinically meaningful improvement in CFTR function with a mean reduction in sweat chloride from a TRIKAFTA baseline of -9.6 mmol/L (95% CI -12.1 to -7.0) through Week 24, with 65% of children reaching a normal sweat chloride value of <30mmol/L. These are unprecedented results for this age group. Vertex expects to submit for approval with global regulators in the first half of 2026.
• Vertex recently initiated a pivotal study of ALYFTREK in children 1 to less than 2 years of age.
• Following positive results from the study of TRIKAFTA in patients one year to less than two years of age, reported in November 2025, Vertex expects to begin submissions for global regulatory approvals in this age group in the first half of 2026.

CASGEVY for the treatment of severe sickle cell disease (SCD) and transfusion-dependent beta thalassemia (TDT)

CASGEVY is a non-viral, ex vivo, CRISPR/Cas9 gene-edited cell therapy for eligible patients with SCD or TDT that has been shown to reduce or eliminate vaso-occlusive crises (VOCs) for patients with SCD and transfusion requirements for patients with TDT. CASGEVY is approved in the U.S., the U.K., the EU, the Kingdom of Saudi Arabia (KSA), the Kingdom of Bahrain, Qatar, Canada, Switzerland, the United Arab Emirates (UAE), and Kuwait for patients 12 years and older with SCD or TDT. In total, there are more than 60,000 eligible patients in these countries, including approximately 37,000 in North America and Europe and more than 23,000 in the Middle East. Recent highlights include:

• Vertex recorded fourth quarter 2025 CASGEVY revenue of $54 million and full year 2025 revenue of $116 million. This reflects 64 patients receiving infusions of CASGEVY in 2025, including 30 people infused in the fourth quarter of 2025. Globally, in 2025, 147 people with SCD or TDT had their first cell collection for CASGEVY.
• As of the end of 2025, approximately 90 percent of patients in the U.S. have reimbursed access to CASGEVY, which is also reimbursed in the U.K., Italy, Austria, Denmark, Luxembourg, KSA, Bahrain, UAE, and Kuwait. Most recently, in January, Vertex secured reimbursed access to CASGEVY for eligible patients with SCD in Scotland, consistent with the reimbursement agreement reached in 2025 for patients with TDT.
• At the American Society of Hematology (ASH) annual meeting in December 2025, Vertex presented positive data from the pivotal studies of CASGEVY in children ages 5 to 11 years old with SCD or TDT, which was highlighted by the conference in the “Best of ASH” presentations. Vertex expects to begin global regulatory submissions for approvals in this age group in the first half of 2026. The U.S. Food and Drug Administration (FDA) awarded Vertex a Commissioner’s National Priority Voucher for this pediatric submission, indicating an accelerated timeline for review once the submission is complete.

JOURNAVX (suzetrigine) for the treatment of moderate-to-severe acute pain

JOURNAVX is a first-in-class, oral, selective, non-opioid Na_V1.8 pain signal inhibitor, approved in the U.S. for the treatment of moderate-to-severe acute pain.

• Since JOURNAVX became available at pharmacies in early March, through year-end 2025, more than 550,000 prescriptions for JOURNAVX have been written and filled across the hospital and retail settings in different acute pain conditions, consistent with JOURNAVX’s broad label.
• Vertex secured commercial coverage for JOURNAVX with the remaining large national pharmacy benefit manager (PBM), effective January 1, 2026, and now has secured access for JOURNAVX with all three national PBMs. As of January 2026, over 200 million individuals across commercial and government payers have coverage, representing two-thirds of U.S. covered lives. In addition, 21 states now provide coverage via Medicaid.
• More than 100 of Vertex’s targeted 150 healthcare systems and more than 950 individual hospitals of the 2,000 targeted institutions have added JOURNAVX to formularies, protocols or order sets.

Select R&D Pipeline Programs

Cystic Fibrosis

• Consistent with its commitment to serial innovation and bringing as many patients as possible to normal levels of CFTR function, Vertex has advanced VX-828, the first of the next-generation 3.0 CFTR corrector class, into a proof-of-concept study in people with CF.

• Vertex continues to advance preclinical assets that inhibit Na_V1.7 for use alone or in combination with a Na_V1.8 inhibitor in acute and neuropathic pain.

IgA Nephropathy (IgAN) and Other B Cell-Mediated Diseases

Vertex is developing povetacicept for multiple diseases. Povetacicept is a dual inhibitor of the BAFF and APRIL cytokines, which play key roles in the pathogenesis of multiple B cell-mediated autoimmune diseases. Povetacicept has pipeline-in-a-product potential and represents a potentially best-in-class approach to control B cell activity in IgAN, primary membranous nephropathy (pMN), and generalized myasthenia gravis (gMG).

• In the fourth quarter of 2025, Vertex initiated the rolling biologics license application (BLA) filing for U.S. accelerated approval of povetacicept in IgAN with submission of the first module. The FDA has granted Breakthrough Therapy Designation for this indication. Vertex remains on track to release interim analysis data in the first half of 2026 and also complete the submission in the first half of 2026, if data from the interim analysis are supportive. Vertex is using a priority review voucher to expedite the review of the povetacicept BLA from ten months to six months.
• Vertex continues to enroll and dose patients in the adaptive Phase 2/3 OLYMPUS pivotal study of povetacicept in people with pMN. Vertex anticipates completing the Phase 2 portion of the study and initiating the Phase 3 portion in mid-2026. The FDA has granted Fast Track and Orphan Drug designations for povetacicept in pMN, and the EMA has granted Priority Medicines (PRIME) designation.
• Vertex expects to initiate a placebo-controlled, Phase 2 dose-ranging proof-of-concept study evaluating povetacicept for the treatment of gMG in the first half of 2026.

APOL1-Mediated Kidney Disease (AMKD)

Vertex has discovered and advanced multiple oral, small molecule inhibitors of APOL1 function, pioneering a new class of medicines that targets the underlying cause of this genetic kidney disease.

• In September, Vertex completed enrollment in the interim analysis cohort of the AMPLITUDE Phase 2/3 trial of inaxaplin in people with primary AMKD and will conduct the pre-planned interim analysis once this cohort reaches 48 weeks of treatment. Vertex expects to share data from the interim analysis in late 2026 or early 2027. The AMPLITUDE study is on track to complete full enrollment in the second half of 2026.
• Vertex expects to complete the AMPLIFIED Phase 2 study of inaxaplin and share data in mid-2026. AMPLIFIED is a study of people with AMKD with moderate proteinuria, and people with AMKD and Type 2 diabetes — populations not being studied in the AMPLITUDE trial.

Type 1 Diabetes (T1D)

Vertex is evaluating stem cell-derived, fully differentiated islet cell therapies for patients suffering from T1D, with the goal of developing a potential one-time functional cure for this disease.

• Vertex has completed enrollment in the Phase 1/2/3 study of zimislecel in people with T1D and has temporarily postponed completion of dosing in the study, pending an ongoing internal manufacturing analysis.
• Zimislecel has been granted Regenerative Medicine Advanced Therapy (RMAT) and Fast Track designations from the U.S. Food and Drug Administration, PRIME designation from the EMA, Breakthrough Medicine designation from the Kingdom of Saudi Arabia, and has secured an Innovation Passport under the Innovative Licensing and Access Pathway (ILAP) from the U.K. Medicines and Healthcare products Regulatory Agency (MHRA).

Autosomal Dominant Polycystic Kidney Disease (ADPKD)

Vertex is developing small molecule correctors that restore function to polycystin 1 (PC1) protein variants, with the goal of addressing the underlying cause of ADPKD.

• Vertex is enrolling and dosing AGLOW, a Phase 2 proof-of-concept study of VX-407 in patients with a subset of variants in the PKD1 gene, which encodes the PC1 protein, estimated to be up to approximately 30,000 (or up to approximately 10%) of the overall patient population living with ADPKD.
• AGLOW is a 24-patient single-arm study that will evaluate the effect of VX-407 on height-adjusted total kidney volume (htTKV). Vertex expects to complete enrollment in the AGLOW study by the end of 2026.

Myotonic Dystrophy Type 1 (DM1)

Vertex is evaluating multiple approaches that target the underlying cause of DM1. Vertex’s lead approach, VX-670, is an oligonucleotide linked to a cyclic peptide, which holds the potential to promote effective delivery into cells and address the causal biology of DM1.

• Vertex continues to enroll and dose the MAD portion of the GALILEO global Phase 1/2 clinical trial of VX-670 in people with DM1; the study is assessing both safety and efficacy. Vertex is on track to complete enrollment and dosing in the trial in mid-2026.

Additional Earlier Stage R&D Programs

Consistent with its overall strategy, Vertex takes a serial innovation approach to all of its programs, with additional assets or approaches across its portfolio.

External Innovation

Consistent with its strategy to develop transformative medicines for serious diseases, Vertex entered into the following transaction:

• An exclusive global license agreement with WuXi Biologics to develop and commercialize a trispecific T cell engager for B cell-mediated autoimmune diseases, which is currently in preclinical development.
