LEXINGTON, Mass., February 28, 2024 – Voyager Therapeutics, Inc. (Nasdaq: VYGR), a biotechnology company dedicated to advancing neurogenetic medicines, today reported fourth quarter and full year 2023 financial and operating results.

​

“As of December 31, 2023, Voyager had approximately $431 million in pro-forma cash on the balance sheet, adjusted for the Novartis agreements and public offering in January 2024. We expect this funding to support the generation of clinical data across multiple programs, with the potential for significant value creation,” said Alfred W. Sandrock, Jr., M.D., Ph.D., Chief Executive Officer of Voyager. “We expect to advance at least four wholly-owned and partnered programs into the clinic by the end of next year. Our most advanced program, the anti-tau antibody VY-TAU01 for Alzheimer’s disease, is expected to reach IND in the first half of this year, and we anticipate generating key tau PET imaging data in the second half of 2026.”

Financial Guidance

Voyager is committed to maintaining a strong balance sheet that supports the advancement and growth of its platform and pipeline. Voyager continues to assess its planned cash needs both during the current period and in future periods. We expect our cash, cash equivalents, and marketable securities including the cash received from the Novartis Collaboration and Licensing Agreement and Stock Purchase Agreement, and the completion of the public offering in January, along with amounts expected to be received as reimbursement for development costs under the Neurocrine and Novartis collaborations, certain near-term milestones, and interest income, to be sufficient to meet Voyager’s planned operating expenses and capital expenditure requirements into 2027.

About the TRACER™ Capsid Discovery Platform
Voyager’s TRACER™ (Tropism Redirection of AAV by Cell-type-specific Expression of RNA) capsid discovery platform is a broadly applicable, RNA-based screening platform that enables rapid discovery of AAV capsids with robust penetration of the blood-brain barrier and enhanced central nervous system (CNS) tropism in multiple species, including non-human primates (NHPs). In preclinical studies, TRACER generated capsids have demonstrated widespread gene expression in the CNS compared to conventional AAV capsids as well as cell- and tissue-specific transduction, including to areas of the brain that have been traditionally difficult to reach, while de-targeting the liver and dorsal root ganglia. As part of its external partnership strategy, Voyager has established multiple collaboration agreements providing access to its next-generation TRACER capsids to potentially enable its partners’ gene therapy programs to treat a variety of diseases.

Forward-Looking Statements

This press release contains forward-looking statements for the purposes of the safe harbor provisions under The Private Securities Litigation Reform Act of 1995 and other federal securities laws. The use of words such as “expect,” “will,” “believe,” “anticipate,” “potential,” “trigger” or “continue,” and other similar expressions are intended to identify forward-looking statements.

For example, all statements Voyager makes regarding Voyager’s ability to advance its AAV-based gene therapy programs and tau antibody program, including expectations for Voyager’s achievement of preclinical and clinical development milestones for its potential development candidates such as IND filings, the initiation of clinical trials, and generation of proof-of-concept; Voyager’s ability to advance gene therapy product candidates under the Neurocrine and Novartis collaborations; Voyager’s anticipated financial results, including the anticipated receipt by Voyager of revenues or reimbursement payments from collaboration partners; and Voyager’s cash runway and ability to generate sufficient cash resources to enable it to continue its business and operations are forward looking.

​

All forward-looking statements are based on estimates and assumptions by Voyager’s management that, although Voyager believes such forward-looking statements to be reasonable, are inherently uncertain. All forward-looking statements are subject to risks and uncertainties that may cause actual results to differ materially from those that Voyager expected. Such risks and uncertainties include, among others, the continued development of Voyager’s technology platforms, including Voyager’s TRACER platform and its antibody screening technology; the ability to initiate and conduct preclinical studies in animal models; the development by third parties of capsid identification platforms that may be competitive to Voyager’s TRACER capsid discovery platform; Voyager’s ability to create and protect intellectual property rights associated with the TRACER capsid discovery platform, the capsids identified by the platform, and development candidates for Voyager’s pipeline programs; the initiation, timing, conduct and outcomes of Voyager’s preclinical and clinical studies; the possibility or the timing of Voyager’s receipt of program reimbursement, development or commercialization milestones, option exercise, and other payments under Voyager’s existing licensing or collaboration agreements; the ability of Voyager to negotiate and complete licensing or collaboration agreements with other parties on terms acceptable to Voyager and the third parties; the ability to attract and retain talented directors, employees, and contractors; and the sufficiency of cash resources to fund its operations and pursue its corporate objectives.

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 pro-forma cash, and net collaboration revenue and net research and development expenses, the latter two of which exclude the impact of reimbursement by Neurocrine Biosciences (Neurocrine) 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.

​

The Company’s pro-forma cash as of December 31, 2023, was $431 million which includes $230.9 million of cash, cash equivalents, and marketable securities as of December 31, 2023, as adjusted for the gross proceeds received from the 2023 Novartis collaboration agreement and our underwritten public offering in January 2024. This does not include any costs associated with executing the Novartis collaboration or the public offering.

​

​

​

Note 1: Under the Company's existing collaboration agreements with Neurocrine, Neurocrine has agreed to be responsible for all costs the Company incurs in conducting preclinical development activities for each Neurocrine collaboration program, 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 and twelve months ended December 31, 2023, we incurred $3.1 million and $10.1 million, respectively, of reimbursable research and development services recorded within collaboration revenue and research and development expenses. During the three and twelve months ended December 31, 2022, we incurred $0.3 million and $0.8 million, respectively, of reimbursable research and development services recorded within collaboration revenue and research and development expenses.
