LEXINGTON, Mass., March 09, 2026 (GLOBE NEWSWIRE) — Voyager Therapeutics, Inc. (Nasdaq: VYGR), a biotechnology company dedicated to leveraging genetics to treat neurological diseases, today reported fourth quarter and full year 2025 financial and operating results.

“Building on our pipeline progress in 2025, Voyager expects 2026 to be a pivotal year defined by three pillars of value creation: data on tau-targeting assets for Alzheimer’s disease, clinical entry for our novel I.V.-delivered neuro gene therapies, and advancement of our nonviral delivery platform, Voyager NeuroShuttle,” said Alfred W. Sandrock, Jr., M.D., Ph.D., Chief Executive Officer of Voyager. “With a strong cash position that is expected to provide runway into 2028, I believe Voyager is poised to execute across multiple clinical programs, further validate our platforms, and build a foundation for long-term shareholder value.”

Fourth Quarter 2025 and Recent Highlights

• Pipeline updates:
  • VY1706 (tau-silencing gene therapy): Voyager expects completion of a good laboratory practice (GLP) toxicology study in Q1 2026, investigational new drug (IND) application submission in Q2 2026, and first-in-human dosing in H2 2026. Following a pre-IND communication with U.S. Food and Drug Administration (FDA) in Q1 2025, Voyager completed a Type C communication with FDA in Q1 2026 and believes there to be a path to IND.
  • VY7523 (anti-tau antibody): Multiple ascending dose (MAD) clinical trial in Alzheimer’s disease (AD) completed enrollment in Q4 2025. Tau positron emission tomography (PET) imaging data are expected in H2 2026.
  • Neurocrine partnership update: Neurocrine has stated that, pending successful FDA IND clearance, it intends to initiate a clinical trial with NBIB-‘223 for Friedreich’s ataxia in H2 2026. Neurocrine has stated that it continues to progress the other four gene therapy programs partnered with Voyager, including the glucosylceramidase beta 1 (GBA1) program. In Q4 2025, Neurocrine initiated a preclinical toxicology study with the fourth development candidate in a gene therapy program partnered with Voyager, triggering a $3 million milestone payment to Voyager.
  • Novartis partnership update: Partnered programs with Novartis for Huntington’s disease, spinal muscular atrophy (SMA), and another undisclosed target continue to advance.

• Early research and platform updates:
  • Voyager NeuroShuttle platform: In a proof-of-concept study using anti-amyloid antibodies, the ALPL-NeuroShuttle showed similar target engagement to a transferrin receptor shuttle after a single IV dose, but with sustained brain exposure. Voyager plans to provide data on NHP translatability, safety, and programs during 2026.
  • Early research: Voyager paused development of its apolipoprotein E (APOE) gene therapy program to prioritize more advanced programs. The decision is unrelated to data from the program, which have demonstrated dose dependent APOE4 protein reduction and APOE2 protein expression in murine studies while maintaining total APOE at physiological levels.

Anticipated 2026 Milestones

• Potentially informative data read-outs expected for tau-targeting agents from third parties
• H2: VY1706 expected to achieve first-in-human dosing in AD
• H2: Tau PET imaging data expected in MAD clinical trial of VY7523 in AD
• H2: Neurocrine intends to initiate a clinical trial with NBIB-‘223 for FA, pending successful FDA IND clearance

Financial Results

• Collaboration Revenues: Collaboration revenue was $15.3 million for the three months ended December 31, 2025, compared to $6.3 million for the same period in 2024, and $40.4 million for the year ended December 31, 2025, compared to $80.0 million for the same period in 2024. The increase for the three months ended December 31, 2025, was primarily due to increased revenue recognized under our Neurocrine Agreement. The decrease for the year ended December 31, 2025, was primarily due to higher collaboration revenue recognized in 2024 in connection with our Neurocrine and Novartis collaboration agreements.
• R&D Expenses: Research and development expenses were $36.0 million for the three months ended December 31, 2025, compared to $35.6 million for the same period in 2024, and $134.7 million for the year ended December 31, 2025, compared to $127.4 million for the same period in 2024. The relatively consistent spend for the three months and year ended December 31, 2025, compared to the respective prior year periods reflects the Company’s portfolio rationalization.
• G&A Expenses: General and administrative expenses were $9.3 million for the three months ended December 31, 2025, compared to $9.0 million for the same period in 2024, and $37.5 million for the year ended December 31, 2025, compared to $35.9 million for the same period in 2024. The relatively consistent spend for the three months and year ended December 31, 2025, compared to the respective prior year periods reflects the Company’s continued disciplined expense management.
• Net Loss: Net loss was $27.4 million for the three months ended December 31, 2025, compared to net loss of $34.5 million for the same period in 2024, and net loss was $119.7 million for the year ended December 31, 2025, compared to $65.0 million for the same period in 2024. The changes for the three months and year ended December 31, 2025, were primarily driven by changes in collaboration revenue discussed above.
• Cash Position: Cash, cash equivalents and marketable securities as of December 31, 2025, were $201.7 million.

Financial Guidance
Voyager is committed to maintaining a strong balance sheet that supports the advancement and growth of its platforms and pipeline. Based on Voyager’s current operating plans, the company expects its cash, cash equivalents, and marketable securities, along with anticipated collaboration reimbursements and interest income, to be sufficient to meet Voyager’s planned operating expenses and capital expenditure requirements into 2028. The Company has the potential to earn additional non-dilutive capital that is not assumed in the cash runway guidance of up to $2.4 billion in development milestone payments.

GAAP vs. Non-GAAP Financial Measures
Voyager’s financial statements are prepared in accordance with generally accepted accounting principles in the United States, or GAAP, and represent revenue and expenses as reported to the Securities and Exchange Commission. Voyager has provided in this release certain financial information that has not been prepared in accordance with GAAP, including net collaboration revenue and net research and development expenses, which exclude the impact of reimbursement by Neurocrine Biosciences (Neurocrine) and Novartis Pharma AG (Novartis) for expenses we incur in conducting preclinical development activities under our collaboration agreements. Management uses these non-GAAP measures to evaluate the Company’s operating performance in a manner that allows for meaningful period-to-period comparison and analysis of trends in its business. Management believes that such non-GAAP measures are important in comparing current results with prior period results and are useful to investors and financial analysts in assessing the Company’s operating performance. Non-GAAP financial measures are not required to be uniformly applied, are not audited and should not be considered in isolation. The non-GAAP measures give investors and financial analysts a better understanding of our net revenue and net research and development expenses without the pass-through impact of Neurocrine costs. The non-GAAP financial information presented here should be considered in conjunction with, and not as a substitute for, the financial information presented in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measures set forth below.

Note 1: Under the Company’s existing collaboration agreements with Neurocrine and Novartis, Neurocrine and Novartis have agreed to be responsible for all costs the Company incurs in conducting preclinical development activities for certain collaboration programs, in accordance with joint steering committee agreed upon workplans and budgets. Reimbursable research and development services performed during the period are captured within collaboration revenue and research and development expenses in the Company’s consolidated statements of operations. During the three months ended December 31, 2025, the Company incurred $1.9 million of reimbursable research and development services recorded within collaboration revenue and research and development expenses. During the three months ended December 31, 2024, the Company incurred $1.9 million of reimbursable research and development services recorded within collaboration revenue and research and development expenses. During the twelve months ended December 31, 2025, the Company incurred $8.1 million of reimbursable research and development services recorded within collaboration revenue and research and development expenses. During the twelve months ended December 31, 2024, the Company incurred $8.5 million of reimbursable research and development services recorded within collaboration revenue and research and development expenses.
