**Voyager Reports First Quarter 2026 Financial and Operating Results**

*- VY1706 and NBIB-'233 completed IND-enabling GLP toxicology; clinical entry expected H2 2026 -*

*- Multiple presentations at ASGCT 2026, including late breaker on VY1706 3-month GLP tox data -*

*- Ended Q1 2026 with cash position of $172 million, runway into 2028 -*

**LEXINGTON, Mass., May 7, 2026** -- Voyager Therapeutics, Inc. (Nasdaq: VYGR), a biotechnology company dedicated to leveraging genetics to treat neurological diseases, today reported first quarter 2026 financial and operating results.

"As the 'Year of Tau' for Alzheimer's disease continues to unfold, Voyager looks forward to third-party data in mid-2026 that have the potential to confirm tau knockdown as the next critical approach to treating Alzheimer's disease. Then, in the second half of the year, we expect first-in-human dosing of our tau silencing gene therapy VY1706 and tau PET imaging efficacy data for our anti-tau antibody VY7523," said Alfred W. Sandrock, Jr., M.D., Ph.D., Chief Executive Officer of Voyager. "With our strong cash position of $172 million that is expected to provide runway into 2028, we continue to execute across our pipeline and platforms."

**First Quarter 2026 and Recent Highlights**

● **Pipeline updates:** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o **VY1706 (tau silencing gene therapy):** Voyager completed investigational new drug (IND)-enabling good laboratory practice (GLP) toxicology in Q1 2026. The U.S. Food and Drug Administration (FDA) IND application process is on track for Q2 2026 to support projected first-in-human dosing in Alzheimer's disease (AD) patients in H2 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o **VY7523 (anti-tau antibody):** Voyager continues to expect tau positron emission tomography (PET) imaging efficacy data in H2 2026 from the ongoing multiple ascending dose (MAD) clinical trial in AD patients.

● **Neurocrine partnership update:** Neurocrine completed GLP toxicology with NBIB-'223 for Friedreich's ataxia (FA) and received FDA orphan drug designation. Neurocrine has stated that it intends to initiate a clinical trial with NBIB-'223 in H2 2026, pending successful FDA IND clearance.

● **Multiple abstracts accepted for presentation at ASGCT 2026**: Voyager will make multiple presentations at the upcoming American Society of Gene & Cell Therapy's (ASGCT) 29th Annual Meeting, including a late-breaking oral presentation on 3-month GLP toxicology data for VY1706, an oral presentation on directed evolution of Voyager's muscular and neuromuscular capsid variants in mice and non-human primates, and multiple poster presentations.

● **Posters on AD programs presented at AD/PD™ 2026:** Preclinical data were shared for VY1706, as well as for Voyager's approach to modulate the expression of APOE4, the strongest genetic risk factor for AD.

------

**Anticipated Upcoming 2026 Milestones**

● Mid-Year: Third-party data that could significantly derisk tau knockdown hypothesis in AD

● 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 $2.6 million for the three months ended March 31, 2026, compared to $6.5 million for the first quarter of 2025. The decrease was primarily attributable to revenue recognized under our Neurocrine and Novartis collaboration agreements in the prior period as the collaborations mature beyond research.

● **Research and Development Expenses:** Research and development expenses were $24.6 million for the first quarter of 2026, compared to $31.5 million for the first quarter of 2025. The decrease was primarily due to cost-cutting and efficiency initiatives, partially offset by an increase in costs related to the tau silencing gene therapy program (VY1706) advancing towards planned clinical trials.

● **General and Administrative Expenses:** General and administrative expenses were $8.3 million for the first quarter of 2026, compared to $9.6 million for the first quarter of 2025. The decrease was primarily attributable to cost-cutting and efficiency initiatives year-over-year.

● **Net Loss:** Net loss was $27.9 million for the first quarter of 2026, compared to $31.0 million for the first quarter of 2025.

● **Cash and Cash Equivalents:** Cash, cash equivalents and marketable securities as of March 31, 2026, were $171.7 million. Based on Voyager's current operating plans, the company expects its cash, cash equivalents, and marketable securities, along with anticipated collaboration reimbursements for work performed and interest income, to be sufficient to meet Voyager's planned operating expenses and capital expenditure requirements into 2028.

**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 March 31, 2026, the Company incurred $1.4 million of reimbursable research and development services recorded within collaboration revenue and research and development expenses. During the three months ended March 31, 2025, the Company incurred $1.6 million of reimbursable research and development services recorded within collaboration revenue and research and development expenses.
