These forward-looking statements are only predictions, and we may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements. You should not place undue reliance on our forward-looking statements. Actual results or events could differ materially from the plans, intentions and expectations disclosed in the forward-looking statements we make. We have based these forward-looking statements largely on our current expectations and projections about future events and trends that we believe may affect our business, financial condition and operating results. We have included important factors in the cautionary statements included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 28, 2024, particularly in “Part I, Item 1A — Risk Factors,” and, if applicable, our Quarterly Reports on Form 10-Q, particularly in “Part II, Item 1A — Risk Factors,” that could cause actual future results or events to differ materially from the forward-looking statements that we make. Our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, strategic collaborations, licenses, joint ventures or investments we may make.

You should read this Quarterly Report on Form 10-Q and the documents that we have filed as exhibits to this Quarterly Report on Form 10-Q with the understanding that our actual future results may be materially different from what we expect. We do not assume any obligation to update any forward-looking statements whether as a result of new information, future events or otherwise, except as required by applicable law.

We obtained the statistical and other industry and market data in this Quarterly Report on Form 10-Q and the documents we have filed as exhibits to the Quarterly Report on Form 10-Q from our own internal estimates and research, as well as from industry and general publications and research, surveys, studies and trials conducted by third parties. Some data is also based on our good faith estimates, which are derived from management’s knowledge of the industry and independent sources. This data involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. In addition, while we believe the market opportunity information included in this Quarterly Report on Form 10-Q and the documents we have filed as exhibits to the Quarterly Report on Form 10-Q is reliable and is based upon reasonable assumptions, such data involves risks and uncertainties and are subject to change based on various factors, including those discussed under “Risk Factors” and in the documents we have filed as exhibits to the Quarterly Report on Form 10-Q. In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this Quarterly Report on Form 10-Q, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

We own various U.S. federal trademark registrations and applications and unregistered trademarks, including our corporate logo. This Quarterly Report on Form 10-Q and the documents filed as exhibits to the Quarterly Report on Form 10-Q contain references to trademarks, service marks and trade names referred to in this Quarterly Report on Form 10-Q and the information incorporated herein, including logos, artwork, and other visual displays, that may appear without the ® or TM symbols, but such references are not intended to indicate, in any way, that we will not assert, to the fullest extent under applicable law, our rights or the rights of the applicable licensor to these trademarks, service marks or trade names.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Nature of business

Voyager Therapeutics, Inc. (the “Company”) is a biotechnology company whose mission is to leverage the power of human genetics to modify the course of and ultimately cure neurological diseases. The Company’s pipeline includes programs for Alzheimer’s disease; amyotrophic lateral sclerosis; Parkinson’s disease, and multiple other diseases of the central nervous system. Many of the Company’s programs are derived from its TRACER™ adeno-associated virus (“AAV”) capsid discovery platform, which the Company has used to generate novel capsids (“TRACER Capsids”) and identify associated receptors to potentially enable high brain penetration with genetic medicines following intravenous dosing. Some of the Company’s programs are wholly-owned, and some are advancing with licensees and collaborators including Alexion, AstraZeneca Rare Disease; Novartis Pharma AG, (“Novartis”); and Neurocrine Biosciences, Inc. (“Neurocrine”).

The Company has a history of incurring annual net operating losses. As of June 30, 2024, the Company had an accumulated deficit of $282.7 million. The Company has not generated any product revenue and has financed its operations primarily through public offerings and private placements of its equity securities, funding from fees, option exercise payments, and milestone payments, and cost reimbursements associated with its prior and ongoing collaborations and license agreements.

As of June 30, 2024, the Company had cash, cash equivalents, and marketable securities of $371.0 million. Based upon the Company’s current operating plans, the Company expects that its existing cash, cash equivalents, and marketable securities at June 30, 2024 to be sufficient to meet the Company’s planned operating expenses and capital expenditure requirements for at least twelve months from the issuance of these consolidated financial statements.

There can be no assurance that the Company will be able to obtain additional debt or equity financing on terms acceptable to the Company or generate product revenue or revenue from collaboration partners, on a timely basis or at all. The failure of the Company to obtain sufficient funds on acceptable terms when needed could have a material adverse effect on the Company’s business, results of operations, and financial condition.

2. Summary of significant accounting policies and basis of presentation

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial reporting. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. For further information, refer to the consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 as filed with the Securities and Exchange Commission (“SEC”) on February 28, 2024. These interim condensed consolidated financial statements, in the opinion of management, reflect all normal recurring adjustments necessary for a fair presentation of the Company’s financial position and results of operations for the periods presented. Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting Standards Codification and Accounting Standards Updates of the Financial Accounting Standards Board.

Principles of Consolidation

The unaudited interim consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary as disclosed in Note 2, under the heading “Summary of Significant Accounting Policies and Basis of Presentation” within the “Notes to Consolidated Financial Statements” accompanying the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023. Intercompany balances and transactions have been eliminated.

Table of Contents

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. On an ongoing basis, the Company’s management evaluates its estimates, which include, but are not limited to, estimates related to revenue recognition, incremental borrowing rate for leases, accrued expenses, stock-based compensation expense, and income taxes. The Company bases its estimates on historical experience and other market-specific or other relevant assumptions that it believes to be reasonable under the circumstances. Actual results may differ from those estimates or assumptions.

Summary of Significant Accounting Policies

There have been no changes in the Company's significant accounting policies as described in Note 2, “Summary of Significant Accounting Policies and Basis of Presentation” within the “Notes to Consolidated Financial Statements” accompanying the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

All of the Company’s marketable securities as of June 30, 2024 have a contractual maturity of one year or less.

The Company reviews investments whenever the fair value of an investment is less than the amortized cost and evidence indicates that an investment’s carrying amount is not recoverable within a reasonable period of time. In connection with these investments, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors, considering the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss on the condensed consolidated balance sheet, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that is not related to credit is recognized in other comprehensive (loss) income. Changes in the allowance for credit losses are recorded as a provision for (or reversal of) credit loss expense in general and administrative expenses within the condensed consolidated statement of operations. Losses are charged against the allowance when the Company believes the uncollectability of an available-for-sale security is confirmed or when either of the criteria regarding intent or requirement to sell is met.

The Company held $268.2 million and $44.2 million in marketable securities that were in an unrealized loss position as of June 30, 2024 and December 31, 2023, respectively. The unrealized losses at June 30, 2024 and December 31, 2023 were attributable to changes in interest rates and do not represent credit losses. The Company does not intend to sell these securities and it is not more likely than not that it will be required to sell them before recovery of their amortized cost basis.

6. Lease obligation

Operating Leases

As of June 30, 2024, the Company has a lease for laboratory and office space at 75 Hayden Avenue in Lexington, Massachusetts through January 31, 2031 and a lease for additional office and laboratory space at 64 Sidney Street in Cambridge, Massachusetts through November 30, 2026.

On August 11, 2023, the Company entered into a first amendment (the “First Amendment”) to its existing lease for laboratory and office space at 75 Hayden Avenue in Lexington, Massachusetts, pursuant to which the Company agreed to lease approximately 61,307 square feet of additional office and laboratory space through January 31, 2031. The Company received $1.8 million of leasehold improvement incentives associated with the First Amendment. The Company gained control of the space on February 1, 2024 and recorded a $26.7 million right-of-use asset and a $26.7 million operating lease liability, accordingly, which reflect the leasehold improvement incentive.

The Company’s lease agreements require the Company to maintain a cash deposit or irrevocable letter of credit in the aggregate amount of $2.9 million payable to its landlords as security for the performance of its obligations under the leases. These amounts are recorded as restricted cash and are included in deposits and other non-current assets in the accompanying condensed consolidated balance sheets.

During the three months ended June 30, 2024, the Company vacated its leased office and laboratory space in Cambridge, Massachusetts. The Company recorded an impairment charge of $2.8 million to operating expenses during the three months ended June 30, 2024 as a result of the carrying value of the leased office and laboratory space asset group exceeding the undiscounted cash flows projected from a planned sublease of the facility which was executed in August 2024, which is disclosed in Note 13 to the unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q. The impairment charge reduced the carrying value of the leased office and laboratory space asset group by $2.8 million.

During the three and six months ended June 30, 2024, the Company incurred lease expenses of $4.4 million and $6.1 million, respectively. During the three and six months ended June 30, 2023, the Company incurred lease expenses

Table of Contents

of $0.9 million and $1.8 million, respectively, for operating leases. As of June 30, 2024, the weighted average remaining lease term was 5.2 years and the weighted average incremental borrowing rate used to determine the operating lease liability was 6.9%.

7. Commitments, contingencies and other liabilities

As of June 30, 2024 and December 31, 2023, other current and non-current liabilities consisted of the following:

Other		1,000		1,001
Total other non-current liabilities	$	41,205	$	18,094

Other Agreements

In 2016, the Company entered into a research and development funding arrangement with a non-profit organization that provides up to $4.0 million in funding to the Company upon the achievement of clinical and development milestones. The agreement provides that the Company repay amounts received under certain circumstances including termination of the agreement, and to pay an amount up to 2.6 times the funding received upon successful development and commercialization of any products developed. In 2017, the Company earned a milestone payment of $1.0 million. The Company evaluated the arrangement and concluded that it represents a research and development financing arrangement as it is probable that the Company will repay amounts received under the arrangement. As a result, the $1.0 million is recorded as a non-current liability in the condensed consolidated balance sheet.

Litigation

The Company was not a party to any material legal matters or claims as of June 30, 2024, or December 31, 2023. The Company did not have contingency reserves established for any litigation liabilities as of June 30, 2024, or December 31, 2023.

8. Significant agreements

The Company’s significant agreements are described in Note 9 of the December 31, 2023 consolidated financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2023. During the three and six months ended June 30, 2024, there were no material changes to the Company’s collaboration agreements or option and license agreements and no new collaboration or license agreements. The Company recorded collaboration revenue of $29.6 million and $4.9 million during the three months ended June 30, 2024 and 2023, respectively. The Company recorded collaboration revenue of $49.1 million and $155.3 million during the six months ended June 30, 2024 and 2023, respectively.

2023 Neurocrine Collaboration Agreement

In April 2024, the Company announced that the joint steering committee with Neurocrine selected a development candidate for the glucocerebrosidase 1 gene therapy program for Parkinson’s disease and other GBA1-mediated diseases (the “GBA1 program”) under the collaboration and license agreement with Neurocrine entered into in January 2023 (the “2023 Neurocrine Collaboration Agreement”). The joint steering committee selection of a

Table of Contents

development candidate for the GBA1 Program triggered a $3.0 million milestone payment to the Company. The Company recorded the $3.0 million as collaboration revenue during the three months ended June 30, 2024.

2023 Novartis Stock Purchase Agreement

Under the stock purchase agreement entered into in December 2023 (the “2023 Novartis Stock Purchase Agreement”), Novartis purchased 2,145,002 shares of common stock of the Company (the “Novartis Shares”) for an aggregate purchase price of approximately $20.0 million. The issuance of the Novartis Shares to Novartis pursuant to the 2023 Novartis Stock Purchase Agreement in January 2024 resulted in a premium of $0.7 million. The premium was allocated to the development and commercialization licenses granted to Novartis for two programs pursuant to the license and collaboration agreement with Novartis entered into in December 2023 and was recognized as collaboration revenue during the first quarter of 2024, upon the issuance of the Novartis Shares under the 2023 Novartis Stock Purchase Agreement.

2019 Neurocrine Collaboration Agreement

In February 2024, the Company announced that the joint steering committee with Neurocrine selected a lead development candidate for the gene therapy program for Friedreich’s ataxia (the “FA Program”) under the collaboration and license agreement with Neurocrine entered into in January 2019 (the “2019 Neurocrine Collaboration Agreement”), which triggered a $5.0 million milestone payment to the Company that was received in the first quarter of 2024. The Company included the $5.0 million that had previously been constrained in the transaction price allocated to the FA Program performance obligation in the three months ended March 31, 2024, accordingly, which resulted in a cumulative catch-up adjustment to collaboration revenue of $4.4 million.

Related Party Collaboration Receivable

The following table presents changes in the balances of the Company’s related party collaboration receivable and contract liabilities for the 2023 Neurocrine Collaboration Agreement and the 2019 Neurocrine Collaboration Agreement during the six months ended June 30, 2024:


	Balance at						Balance at
	December 31, 2023		Additions		Deductions		June 30, 2024

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited condensed consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q and the audited financial information and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2023, which was filed with the Securities and Exchange Commission, or the SEC, on February 28, 2024.

Our actual results and timing of certain events may differ materially from the results discussed, projected, anticipated, or indicated in any forward-looking statements. We caution you that forward-looking statements are not guarantees of future performance and that our actual results of operations, financial condition and liquidity, and the development of the industry in which we operate may differ materially from the forward-looking statements contained in this Quarterly Report on Form 10-Q. The following information and any forward-looking statements should be considered in light of factors discussed in Part I, Item 1A, "Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, 2023, and, if applicable, those included under Part II, Item 1A of our Quarterly Reports on Form 10-Q, that could cause actual future results or events to differ materially from the forward-looking statements that we make.

Overview

We are a biotechnology company whose mission is to leverage the power of human genetics to modify the course of and ultimately cure neurological diseases. Our pipeline includes programs for Alzheimer’s disease, or AD; amyotrophic lateral sclerosis, or ALS; Parkinson’s disease; and multiple other diseases of the central nervous system, or CNS. Many of our programs are derived from our TRACER™ (Tropism Redirection of AAV by Cell-type-specific Expression of RNA) adeno-associated virus, or AAV, capsid discovery platform, which we have used to generate novel capsids, or TRACER Capsids, and identify associated receptors to potentially enable high brain penetration with genetic medicines following intravenous dosing. Some of our programs are wholly-owned, and some are advancing with licensees and collaborators including Alexion, AstraZeneca Rare Disease, or Alexion; Novartis Pharma AG, or Novartis; and Neurocrine Biosciences, Inc., or Neurocrine.

We focus on leveraging our expertise in capsid discovery and neuropharmacology to address the delivery hurdles that have constrained the genetic medicine and neurology disciplines, with the goal of either halting or slowing disease progression or reducing symptom severity, and therefore providing clinically meaningful impact to patients. We are advancing our own proprietary pipeline of drug candidates for neurological diseases, with a focus on AD. Our wholly-owned prioritized pipeline programs include an anti-tau antibody for AD; a superoxide dismutase 1, or SOD1, silencing gene therapy for ALS; and a tau silencing gene therapy for AD. We identified a lead development candidate for our anti-tau antibody program in the first quarter of 2023, which we refer to as VY7523 (formerly referred to as VY-TAU01). We submitted an investigational new drug, or IND, application to the U.S. Food and Drug Administration, or the FDA, for VY7523 in March 2024 and we have obtained clearance of the IND. In May 2024, we dosed the first participant in our Phase 1a single ascending dose, or SAD, trial of VY7523 in healthy volunteers. We expect top-line safety and pharmacokinetic data from our SAD trial in the first half of 2025. We expect to initiate a Phase 1b multiple ascending dose, or MAD, trial of VY7523 in patients with early AD in 2025, which has the potential to generate initial data for slowing the spread of pathological tau via tau positron emission tomography, or PET, imaging in the second half of 2026. We identified a lead development candidate for the SOD1 silencing gene therapy program in the fourth quarter of 2023, which we refer to as VY9323, and we expect to submit the IND application for this program in mid-2025. We completed the pre-IND meeting with the FDA for the VY9323 program in May 2024 and initiated Good Laboratory Practice, or GLP, toxicology studies in July 2024. We promoted our tau silencing gene therapy program to a prioritized program in the first quarter of 2024, based on preclinical data demonstrating robust reductions in tau messenger RNA, or mRNA, in a murine model, and we anticipate submission of an IND for this program in 2026. Our proprietary pipeline also includes an early research initiative to develop a gene therapy for the treatment of AD. This program seeks to combine a vectorized anti-amyloid antibody with a TRACER Capsid.

We are also working with our collaboration partners on multiple programs. In January 2019 and January 2023, we entered into collaboration and license agreements with Neurocrine. Under our agreements with Neurocrine, we are

Table of Contents

actively advancing two later preclinical stage programs: a glucocerebrosidase 1, or GBA1, gene therapy program for Parkinson’s disease and other GBA1-mediated diseases, or the GBA1 Program, and a frataxin, or FXN, gene therapy program for Friedreich’s ataxia, or the FA Program. The joint steering committee with Neurocrine selected a development candidate for the FA Program in February 2024, and we and Neurocrine expect to file an IND application with the FDA for the FA Program in 2025. The joint steering committee with Neurocrine also selected a development candidate for the GBA1 Program in April 2024, and we and Neurocrine expect to file an IND application with the FDA for the GBA1 Program in 2025. Pursuant to our agreements with Neurocrine, we are also working with Neurocrine on five early-stage programs for the research, development, manufacture and commercialization of gene therapies designed to address central nervous system diseases or conditions associated with rare genetic targets. In December 2023, we entered into a license and collaboration agreement with Novartis to provide Novartis certain rights regarding the development of potential gene therapy product candidates for the treatment of spinal muscular atrophy and to collaborate with Novartis to develop gene therapy product candidates for the treatment of Huntington’s disease. We have also entered into agreements with licensees including Novartis and Alexion to license or to provide options to receive exclusive licenses to certain TRACER Capsids.

All of the gene therapies in our wholly-owned and collaborative pipeline leverage novel capsids derived from our TRACER™ Capsid discovery platform. TRACER 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 CNS tropism in multiple species, including non-human primates.

Overview of Our Pipeline

We have leveraged our TRACER discovery platform and other gene therapy platforms, our expertise with proprietary antibodies, vectorized small interfering RNA, or siRNA, knockdown, gene delivery and our vectorized antibody platform to assemble a pipeline of proprietary antibody, AAV gene therapy and other genetic medicine programs for the treatment of neurological diseases. We have prioritized pipeline programs for our development based on the following criteria: high unmet medical need, target validation, efficient path to human proof of biology, robust preclinical pharmacology, and strong commercial potential. Depending on the disease, we are seeking to develop AAV gene therapies that will use a gene replacement, gene silencing or vectorized antibody approach, and antibodies that will use a passive administration approach.

Our pipeline of programs is summarized in the table below:

Wholly-Owned Programs

Anti-Tau Antibody (VY7523 – formerly VY-TAU01) for the Treatment of Alzheimer’s Disease

Our Treatment Approach

We selected VY7523 as our lead humanized anti-tau antibody candidate to advance against AD. VY7523 is an intravenously administered, recombinant, humanized IgG4 monoclonal antibody developed to inhibit the spread of pathological tau, which is closely correlated with disease progression and cognitive decline in AD. In contrast to previous N-terminal directed anti-tau antibodies that did not show efficacy in clinical studies, VY7523 targets a distinct C-terminal epitope of tau and has demonstrated robust in vivo inhibition of the spread of pathological tau in a preclinical model. Additional preclinical studies have demonstrated that VY7523 was well-tolerated and demonstrated a favorable pharmacokinetic profile following intravenous administration.

Program Status

In January 2023, we selected VY7523 as our lead humanized anti-tau antibody candidate to advance against AD. We submitted an IND application for VY7523 to the FDA in March 2024 and we obtained clearance of the IND. In May 2024 we dosed the first participant in our Phase 1a SAD trial in healthy volunteers. Enrollment is on track, with a total of approximately 48 participants expected to enroll across multiple cohorts. We expect top-line safety and pharmacokinetic data from our SAD trial in the first half of 2025. A Phase 1b MAD trial in participants with early AD is expected to be initiated in 2025. The MAD trial has the potential to generate initial data for slowing the spread of pathological tau via tau PET imaging in the second half of 2026.

SOD1 Silencing Gene Therapy Program for the Treatment of ALS (VY9323)

Our Treatment Approach

We believe that a therapeutic delivering a vectorized highly potent siRNA construct via intravenous administration of an AAV gene therapy may enable broad CNS knockdown of SOD1, which could potentially slow the decline of functional ability in ALS patients with the SOD1 mutation. We have selected a potent, specific vectorized siRNA transgene targeting SOD1, delivered using a novel TRACER Capsid. We believe that a Phase 1 clinical trial to

demonstrate reductions in SOD1 in the cerebrospinal fluid and in neurofilament light chain in the plasma could provide evidence of target engagement and the attenuation of motor neuron loss, respectively.

Program Status

We have identified VY9323, a potent and specific vectorized siRNA transgene that resulted in substantially extended lifespan and motor function when delivered using a BBB-penetrant capsid in a mouse model. In December 2023, we selected VY9323 as our lead development candidate for our SOD1 program. We plan to submit an IND application to the FDA in mid-2025 for VY9323 and to initiate a Phase 1 clinical trial of VY9323 in subjects with SOD1 ALS for the program as soon as possible thereafter. We completed a pre-IND meeting with the FDA in May 2024 and initiated GLP toxicology studies designed to support a potential IND filing. We expect to evaluate the safety and biological activity of VY9323 in this Phase 1 trial.

Tau Silencing Gene Therapy Program for the Treatment of AD

Our Treatment Approach

We have maintained a long-standing focus on developing proprietary and complimentary approaches to disrupt the progression of tau pathology believed to be central to AD and other tauopathies. A reduction of toxic tau aggregates may slow disease progression and cognitive decline in these diseases. In addition to our aforementioned anti-tau antibody program, we are advancing a gene therapy that leverages an intravenously delivered TRACER Capsid containing a vectorized siRNA, specifically targeting tau mRNA.

Program Status

In the first quarter of 2024, we promoted the tau silencing gene therapy program to a prioritized program on our wholly-owned pipeline, based on its demonstration on in vivo proof-of-concept and expected advancement to IND within two to three years. We are evaluating the optimal combination of payload and capsid for this program, to enable selection of a development candidate. We expect to file an IND for this program in 2026.

Vectorized Anti-Amyloid Antibody Early Research Program for the Treatment of AD

In August 2023, we announced an early research initiative investigating a gene therapy targeting anti-amyloid for the treatment of AD. The program combines a vectorized anti-amyloid antibody with an intravenously delivered TRACER Capsid.

Collaboration Programs

Friedreich’s Ataxia Program: VY-FXN01 (2019 Neurocrine Collaboration)

Our Treatment Approach

We are seeking to develop an AAV gene therapy approach that we believe will deliver a functional version of the FXN gene to the sensory pathways through intravenous injection. We think this approach has the potential to improve balance, ability to walk, sensory capability, coordination, strength and functional capacity of Friedreich’s ataxia patients. Most Friedreich’s ataxia patients produce low levels of the frataxin protein, which although insufficient to prevent the disease, exposes the patient’s immune system to frataxin. This reduces the likelihood that the FXN protein expressed by AAV gene therapy will trigger a harmful immune response.

Our Program Status

Under the collaboration and license agreement with Neurocrine entered into in January 2019, or the 2019 Neurocrine Collaboration Agreement, we are developing VY-FXN01 for the treatment of Friedreich’s ataxia. VY-FXN01 is currently in preclinical development. In February 2024, the joint steering committee with Neurocrine selected a development candidate combining an FXN gene replacement payload with a novel TRACER Capsid for its FA Program and we and Neurocrine expect to file an IND application with the FDA for the FA Program in 2025. The

Table of Contents

selection of a lead development candidate triggered a $5.0 million milestone payment to us, which we received in March 2024.

GBA1 Gene Replacement Program for the Treatment of Parkinson’s Disease (2023 Neurocrine Collaboration)

Our Treatment Approach

We believe that restoring the activity of the gene encoding the lysosomal glucocerebrosidase enzyme, or Gcase, may attenuate disease progression and potentially slow neurodegeneration. We anticipate delivering GBA1 via intravenous administration of an AAV gene therapy to enable widespread distribution to multiple affected brain regions and to avoid the need for more invasive approaches. We believe that the measurement of the Gcase substrates such as glucosylsphingosine as cerebrospinal fluid biomarkers may facilitate efficient clinical demonstration of proof-of-biology. Such substrates of the Gcase enzyme are elevated in the cerebrospinal fluid of Parkinson’s disease patients who harbor the GBA1 mutation, and we expect that substrate levels would be normalized if our gene therapy restores Gcase enzyme expression in the brain. This gene therapy may also have potential utility in idiopathic Parkinson’s disease, where there is evidence of loss of Gcase activity in the substantia nigra in Parkinson’s disease patients even in the absence of GBA1 mutations as well as evidence of lysosomal dysfunction in general.

Program Status

Under the collaboration and license agreement with Neurocrine entered into in January 2023, or the 2023 Neurocrine Collaboration Agreement, we are developing gene therapy products directed to the gene that encodes GBA1 for the treatment of Parkinson’s disease and other diseases associated with GBA1, or the GBA1 Program. The GBA1 Program is currently in preclinical development. In April 2024, the joint steering committee with Neurocrine selected a development candidate for the GBA1 Program and we and Neurocrine expect to file an IND application with the FDA for the GBA1 Program in 2025. The selection of this development candidate triggered a $3.0 million milestone payment, which we received in the second quarter of 2024.

HD Program (2023 Novartis Collaboration Agreement)

Program Status

On December 28, 2023, or the 2023 Novartis Collaboration Agreement Effective Date, we entered into a license and collaboration agreement with Novartis, or the 2023 Novartis Collaboration Agreement. Under the 2023 Novartis Collaboration Agreement, we and Novartis have agreed to collaborate to develop AAV gene therapy products and product candidates intended for the treatment of Huntington’s disease, which we refer to as the Novartis HD Program. The Novartis HD Program is currently in preclinical development. From and after the first IND application filing for the Novartis HD Program, we and Novartis have agreed that Novartis will assume sole responsibility for the development and commercialization of gene therapy products and product candidates under the Novartis HD Program, including all further preclinical and clinical development and any commercialization of the Novartis HD Program products and product candidates.

Further, Novartis has also agreed not to, and to cause its affiliates not to sell or transfer any of the Novartis Shares without our prior approval, subject to specified conditions.

2022 Novartis Option and License Agreement

On March 4, 2022, or the 2022 Novartis Option and License Effective Date, we entered into an option and license agreement with Novartis, or the 2022 Novartis Option and License Agreement. Pursuant to the 2022 Novartis Option and License Agreement, we granted Novartis options, or the Novartis License Options, to license TRACER Capsids, or the Novartis Licensed Capsids, for exclusive use with certain targets to develop and commercialize AAV gene therapy candidates comprised of Novartis Licensed Capsids and payloads directed to such targets, or the Novartis Payloads.

Under the terms of the 2022 Novartis Option and License Agreement, Novartis paid us an upfront payment of $54.0 million. Effective as of March 1, 2023, Novartis exercised its Novartis License Options to license TRACER Capsids for use in gene therapy programs against two undisclosed programs targeting specified genes, or the Initial Novartis Targets. With Novartis’ option exercise on two Initial Novartis Targets, we received a $25.0 million option exercise payment in April 2023, and are eligible to receive associated potential development, regulatory, and commercial milestone payments, as well as mid- to high-single-digit tiered royalties based on net sales of products containing the corresponding Novartis Payload, or the Novartis Licensed Products, incorporating the Novartis Licensed Capsids. The two Initial Novartis Targets licensed are distinct from targets in our wholly-owned and partnered pipeline. In addition, during the research term, Novartis retains the right to expand the agreement to include options to license capsids for up to two other targets, or the Additional Novartis Targets, subject to their availability, for a fee of $18.0 million per Additional Novartis Target. Under such an expansion, we would be eligible to receive a $12.5 million license option exercise fee for each Additional Novartis Target exercised, as well as future potential milestone payments per Additional Novartis Target and tiered mid- to high-single digit royalties on the Novartis Licensed Products incorporating the Novartis Licensed Capsids.

Table of Contents

Novartis elected not to license a capsid for one Initial Novartis Target under the 2022 Novartis Option and License Agreement prior to the expiration of the applicable Novartis License Option. As a result, the non-exclusive research license that we granted to Novartis in connection with this Initial Novartis Target has terminated, the research term for this Initial Novartis Target has expired, and we are no longer eligible to receive development, regulatory, and commercial milestone payments or royalties in connection with this Initial Novartis Target. All capsid rights with respect to that Initial Novartis Target have returned to us.

2023 Neurocrine Collaboration Agreement

In January 2023, we entered into a collaboration agreement, or the 2023 Neurocrine Collaboration Agreement, with Neurocrine for the research, development, manufacture and commercialization of certain of our AAV gene therapy products. Under the 2023 Neurocrine Collaboration Agreement, we agreed to collaborate on the conduct of four collaboration programs, which we refer to collectively as the 2023 Neurocrine Programs: the GBA1 Program, and three new programs focused on the research, development, manufacture and commercialization of gene therapies designed to address central nervous system diseases or conditions associated with rare genetic targets, or the 2023 Discovery Programs.

Under the terms of the 2023 Neurocrine Collaboration Agreement, Neurocrine paid us an upfront payment of approximately $136.0 million and approximately $39.0 million as consideration for an equity purchase of 4,395,588 shares of our common stock in February 2023. The 2023 Neurocrine Collaboration Agreement provides for aggregate development milestone payments from Neurocrine to us for the research, development, manufacture, and commercialization of gene therapy products, or the 2023 Collaboration Products, under (a) the GBA1 Program of up to $985.0 million; and (b) each of the three 2023 Discovery Programs of up to $175.0 million for each 2023 Discovery Program. We may be entitled to receive aggregate commercial milestone payments for up to two 2023 Collaboration Products under the GBA1 Program of up to $950.0 million per 2023 Collaboration Product and for one 2023 Collaboration Product under each 2023 Discovery Program of up to $275.0 million per 2023 Discovery Program. The joint steering committee’s selection of the development candidate for the GBA1 Program in April 2024 triggered a $3.0 million milestone payment, which we received in May 2024.

Neurocrine has also agreed to pay us tiered royalties, based on future net sales of the 2023 Collaboration Products. Such royalty percentages, for net sales in and outside the United States, range from (a) for the GBA1 Program, the low double-digits to twenty and the high single-digits to mid-teens, respectively, and (b) for each 2023 Discovery Program, high single-digits to mid-teens and mid-single digits to low double-digits, respectively. On a country-by-country and 2023 Neurocrine Program-by-2023 Neurocrine Program basis, the parties have agreed royalty payments would commence on the first commercial sale of a 2023 Collaboration Product in such country and terminate upon the latest of (x) the expiration, invalidation or the abandonment of the last patent covering the composition of the 2023 Collaboration Product or its approved method of use in such country, (y) ten years from the first commercial sale of the 2023 Collaboration Product in such country and (z) the expiration of regulatory exclusivity in such country, or the 2023 Royalty Term. Royalty payments may be reduced by up to 50% in specified circumstances, including expiration of patent rights related to a 2023 Collaboration Product, approval of biosimilar products in a given country, or required payment of licensing fees to third parties related to the development and commercialization of any 2023 Collaboration Product.

Other License Agreements

Alexion License Agreement

In October 2021, we entered into an option and license agreement, or the Pfizer Agreement, with Pfizer Inc., or Pfizer, pursuant to which we granted Pfizer options to receive an exclusive license, or the Pfizer License Options, to certain TRACER Capsids to develop and commercialize certain AAV gene therapy candidates comprised of a capsid and specified Pfizer transgenes, or Pfizer Transgenes. Effective as of September 30, 2022, Pfizer exercised a Pfizer License Option with respect to a capsid for the specified Pfizer Transgene for potential treatment of a rare neurological disease. In connection with the exercise of the Pfizer License Option for a rare neurological disease, we granted Pfizer an exclusive, worldwide license, with the right to sublicense, under certain of our intellectual property, the rights to develop and commercialize rare neurological disease products utilizing the capsid candidate and incorporating the corresponding Pfizer Transgene, or the Pfizer Licensed CNS Products. Pfizer did not exercise its option to license a capsid for the potential treatment of a cardiovascular disease. As result, Pfizer’s right to exercise a Pfizer License Option for a

Table of Contents

cardiovascular disease has terminated in accordance with the terms of the Pfizer Agreement and all rights to capsids for that cardiovascular disease have reverted to us.

Effective upon the closing of a transaction on September 20, 2023, Alexion, AstraZeneca Rare Disease, or Alexion, acquired all of Pfizer’s rights under the Pfizer Agreement and became the successor-in-interest to Pfizer thereunder. We refer to the Pfizer Agreement following the acquisition, as the Alexion Agreement. The acquisition does not impact the material terms of the option and license agreement.

Under the terms of the Alexion Agreement, we have received an upfront payment of $30 million and a payment of $10 million in connection with the exercise of the Pfizer License Option, which we also refer to as the Alexion License Option, for a rare neurological disease during the fourth quarter of 2022. We are also eligible to receive specified development, regulatory, and commercialization milestone payments of up to an aggregate of $115 million for the first Pfizer Licensed CNS Product, which we also refer to as an Alexion Licensed CNS Product, to achieve the applicable milestone. On an Alexion Licensed CNS Product-by-Alexion Licensed CNS Product basis, we are also eligible to receive (a) specified sales milestone payments of up to an aggregate of $175 million per Alexion Licensed CNS Product and (b) tiered, escalating royalties in the mid- to high-single-digit percentages of annual net sales of each Alexion Licensed CNS Product. The royalties are subject to potential reductions in customary circumstances including patent claim expiration, payments for certain third-party licenses, and biosimilar market penetration, subject to specified limits. For a further description of the Alexion Agreement, refer to Note 9, Significant Agreements, to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2023 under the caption “Alexion Option and License Agreement (Formerly Pfizer Option and License Agreement).”

The terms of the Touchlight License Agreement include a one-time, non-refundable technology access fee of $5.0 million, paid to Touchlight during the fourth quarter of 2022. The terms of the Touchlight License Agreement also include future milestone payments and low single-digit royalties payable to Touchlight by us if we or our program collaborators or licensees choose to utilize in a therapeutic product certain TRACER Capsids that were created with the historical use of the Subject DNA Preparation Process. Additionally, we are obligated to pay low single-digit royalties to Touchlight on future payments we receive in connection with licensing of certain TRACER Capsids that were created with the historical use of the Subject DNA Preparation Process, excluding the licensing of or collaboration on any of our therapeutic programs.

2024 Underwritten Public Offering

In January 2024, we issued and sold 7,777,778 shares of our common stock and, in lieu of common stock to certain investors, pre-funded warrants to purchase 3,333,333 shares of common stock in a public offering, or the 2024 Public Offering, at a public offering price of $9.00 per share of common stock and $8.999 per pre-funded warrant. The 2024 Public Offering resulted in net proceeds to the Company of approximately $93.5 million after deducting underwriting discounts and commissions and offering expenses.

Each pre-funded warrant has an exercise price of $0.001 per share and is exercisable for one share of common stock from the date of issuance until the pre-funded warrant is exercised in full. Under the terms of the pre-funded warrants, we may not effect the exercise of any such warrant, and a holder will not be entitled to exercise any portion of any such warrant, that, upon giving effect to or immediately prior to, would cause: (1) the aggregate number of shares of our common stock beneficially owned by such holder (together with its affiliates) to exceed 9.99% of the number of shares of our common stock outstanding immediately after giving effect to the exercise; or (2) the combined voting power of our securities beneficially owned by such holder (together with its affiliates) to exceed 9.99% of the combined voting power of all of our securities outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the pre-funded warrants. However, any holder of a pre-funded warrant may increase or decrease such percentage to any other percentage not in excess of 19.99% provided that any such increase will not be effective until the 61^st day after notice from the holder is delivered to us.

fees for maintaining licenses under our third-party licensing agreements.

Research and development costs are expensed as incurred. Costs for certain activities, such as manufacturing, preclinical studies, and clinical trials, are generally recognized based on an evaluation of the progress to completion of specific tasks using information and data provided to us by our vendors and collaborators.

Research and development activities are central to our business model. We are in the early stages of development of our product candidates. During the six months ended June 30, 2024, our research and development expenses have increased as compared to the amounts recorded in the same period in the prior year. As our research and development programs progress and as we identify product candidates and initiate preclinical studies and clinical trials, including our SAD clinical trial to evaluate VY7523 (formerly referred to as VY-TAU01) which we initiated in the first half of 2024, we expect research and development costs to continue to increase. At this time, we cannot reasonably

Table of Contents

estimate or know the nature, timing and estimated costs of the efforts that will be necessary to complete the development of our product candidates.

Because of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to accurately predict the timing or amount of increased expenses. Our expenses will increase if:

●

we are required by the FDA or the European Medicines Agency or other regulatory agencies to redesign or modify trials or studies or to perform trials or studies in addition to those currently expected;

●

there are any delays in the receipt of regulatory clearance to begin our planned clinical programs; or

●

there are any delays in enrollment of patients in or completing our clinical trials or the development of our product candidates.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and other related costs, including stock-based compensation, for personnel in executive, finance, accounting, information technology, business development, legal and human resource functions. Other significant costs include corporate facility costs not otherwise included in research and development expenses, legal fees related to patent and corporate matters and fees for accounting and consulting services.

During the six months ended June 30, 2024, our general and administrative expenses have increased as compared to the amount recorded in the same period in prior year, primarily due to increased facilities costs and increased employee related costs.

Other Income, Net

Other income consists primarily of interest income on our marketable securities.

Critical Accounting Policies and Estimates

We believe that several accounting policies are important to understanding our historical and future performance. We refer to these policies as critical because these specific areas generally require us to make judgments and estimates about matters that are uncertain at the time we make the estimate. There were no changes to our critical accounting policies during the six months ended June 30, 2024, as compared to those identified in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023. It is important that the discussion of our operating results that follow be read in conjunction with the critical accounting policies disclosed in Item 7 “Critical Accounting Policies and Estimates” in our Annual Report on Form 10-K, as filed with the SEC on February 28, 2024.

Research and Development Expense

Research and development expenses increased by $12.5 million from $22.0 million for the three months ended June 30, 2023, to $34.5 million for the three months ended June 30, 2024. The increase in research and development expenses for the three months ended June 30, 2024 was primarily attributable to the following:

●

approximately $6.0 million for increased facility and other costs primarily related to our lease for additional laboratory and office space at 75 Hayden Avenue in Lexington, Massachusetts, which we took occupancy of on February 1, 2024, along with our impairment charge on our leased office and laboratory space in Cambridge, Massachusetts;

●

approximately $3.7 million for increased employee and consultant related costs associated with higher headcount in research and development functions, including targeted development team hires to support our advancing pipeline as compared to the three months ended June 30, 2023; and

●

approximately $2.4 million for external research and development costs related to increased program-related spending, particularly on our anti-tau antibody program and SOD1 program, along with spend on the Novartis HD Program during the second quarter of 2024.

General and Administrative Expense

General and administrative expense increased by $1.9 million from $8.3 million for the three months ended June 30, 2023, to $10.2 million for the three months ended June 30, 2024. The increase in general and administrative expense was primarily attributable to increased facilities costs and increased employee related costs.

Other Income, net

Other income, net increased by approximately $1.6 million. Other income, net during both the three months ended June 30, 2024 and 2023 primarily reflects interest income on marketable securities balances. The increase was due to increased balances of marketable securities during the three months ended June 30, 2024, as compared to the three months ended June 30, 2023.

Comparison of the six months ended June 30, 2024 and 2023

Research and Development Expense

Research and development expense increased by $21.0 million from $40.6 million for the six months ended June 30, 2023 to $61.5 million for the six months ended June 30, 2024. The increase in research and development expense was primarily attributable to the following:

●

approximately $8.4 million for increased facility and other costs primarily related to our lease for additional laboratory and office space at 75 Hayden Avenue in Lexington, Massachusetts, which we took occupancy of on February 1, 2024, along with our impairment charge on our leased office and laboratory space in Cambridge, Massachusetts;

●

approximately $6.6 million for increased employee and consultant related costs associated with higher headcount in research and development functions as compared to the same period in the prior year; and

●

approximately $5.1 million for external research and development costs related to increased program-related spending, particularly on our anti-tau antibody program and SOD1 program and spend on the Novartis HD Program.

General and Administrative Expense

General and administrative expense increased by $1.4 million from $17.3 million for the six months ended June 30, 2023, to $18.8 million for the six months ended June 30, 2024. The increase in general and administrative expense was primarily attributable to increased facilities costs and increased employee related costs.

Other Income, net

Other income, net increased by approximately $4.6 million. Other income, net during both the six months ended June 30, 2024 and 2023 primarily reflects interest income on marketable securities balances. The increase was due to

Table of Contents

increased balances of marketable securities during the six months ended June 30, 2024, as compared to the six months ended June 30, 2023.

Liquidity and Capital Resources

Sources of Liquidity

We have funded our operations primarily through private placements of redeemable convertible preferred stock, public offerings of our common stock and pre-funded warrants to acquire our common stock, private placements of our common stock, and strategic collaborations and option and license arrangements, including our strategic collaborations and option and license agreements with Neurocrine, Novartis, and Alexion.

During the six months ended June 30, 2024, the 2024 Public Offering resulted in net proceeds to the Company of approximately $93.5 million after deducting underwriting discounts and commissions and offering expenses.

We and Novartis entered into the 2023 Novartis Stock Purchase Agreement, on December 28, 2023, for the sale and issuance of 2,145,002 shares of our common stock to Novartis at a price of $9.324 per share, for an aggregate purchase price of approximately $20.0 million. In accordance with the terms and conditions of the 2023 Novartis Stock Purchase Agreement, we issued and sold these shares to Novartis on January 3, 2024.

Cash Flows

The following table provides information regarding our cash flows for the six months ended June 30, 2024 and 2023:


	Six Months Ended
	June 30,
	2024		2023

	(in thousands)
Net cash provided by (used in):
Operating activities	$	27,187	$	122,730
Investing activities		(132,008)		(10,172)
Financing activities		113,427		32,854
Net increase in cash, cash equivalents, and restricted cash	$	8,606	$	145,412

Net Cash Provided by Operating Activities

Net cash provided by operating activities was $27.2 million during the six months ended June 30, 2024, compared to $122.7 million of net cash provided by operating activities during the six months ended June 30, 2023. The decrease was primarily due to our net loss during the 2024 period as compared to net income during the 2023 period.

Net Cash Used in Investing Activities

Net cash used in investing activities was $132.0 million during the six months ended June 30, 2024, compared to $10.2 million during the six months ended June 30, 2023. The change was primarily due to increased purchases of marketable securities during the six months ended June 30, 2024 as compared to the six months ended June 30, 2023.

Net Cash Provided by Financing Activities

Net cash provided by financing activities was $113.4 million during the six months ended June 30, 2024, driven by proceeds from the issuance of common stock and pre-funded warrants in connection with the 2024 Public Offering and the issuance of common stock in connection with the 2023 Novartis Stock Purchase Agreement. Net cash provided by financing activities during the six months ended June 30, 2023 was driven by proceeds from the issuance of common stock in connection with the 2023 Neurocrine Collaboration Agreement.

Table of Contents

Funding Requirements

Our expenses increased during the six months ended June 30, 2024, as compared with the six months ended June 30, 2023, as our development programs progressed and we increased headcount. We expect our expenses to continue to increase as we continue the research and development of, conduct clinical trials of, and seek marketing approval for our product candidates, including our Phase 1a SAD clinical trial to evaluate VY7523 initiated in the first half of 2024, and as we continue to perform our obligations in connection with our collaboration agreements. In addition, if we obtain marketing approval for any of our product candidates, we expect to incur significant expenses related to program sales, marketing, manufacturing and distribution for our wholly-owned programs and to the extent that such sales, marketing and distribution are not the responsibility of potential collaborators, as applicable. Furthermore, we expect to incur increasing costs associated with operating as a public company, executing financial statement controls, satisfying regulatory and quality standards, fulfilling healthcare compliance requirements, and maintaining product, clinical trial and directors’ and officers’ liability insurance coverage. We also anticipate the cost of goods and services and the levels of compensation paid to employees will increase due to market conditions existing in the general economy. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise capital or enter into business development transactions when needed or on acceptable terms, we could be forced to delay, reduce or eliminate our research and development programs or any future commercialization efforts.

As of June 30, 2024, we had cash, cash equivalents, and marketable securities of $371.0 million. Based upon our current operating plans, we expect that our existing cash, cash equivalents, and marketable securities at June 30, 2024, along with amounts expected to be received as reimbursement for development costs under our collaboration and license agreements with Neurocrine and Novartis, and interest income, to be sufficient to meet our planned operating expenses and capital expenditure requirements into 2027. Our future capital requirements will depend on many factors, including:

●

the scope, progress, results, and costs of product discovery, preclinical studies and clinical trials for our product candidates, including our Phase 1a SAD clinical trial to evaluate VY7523 initiated in the first half of 2024;

●

the scope, progress, results, costs, prioritization, and number of our research and development programs;

●

the progress and status of our strategic collaborations and option and license agreements and any similar arrangements we may enter into in the future, including any research and development costs for which we are responsible, future additional obligations that we may be committed to in connection with these agreements, and our receipt of any future milestone payments and royalties from our collaboration partners or licensors;

●

the extent to which we are obligated to reimburse preclinical development and clinical trial costs, or the achievement of milestones or occurrence of other developments that trigger milestone and royalty payments, under any collaboration or license agreements to which we might become a party, such as the Touchlight License Agreement;

●

the costs, timing and outcome of regulatory review of our product candidates;

●

our ability to establish and maintain collaboration, distribution, or other marketing arrangements for our product candidates on favorable terms, if at all;

●

the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims;

●

the extent to which we acquire or in-license other product candidates and technologies, including any intellectual property associated with such candidates or technologies, acquire or invest in other businesses, or out-license our product candidates, capsids or other technologies;

Table of Contents

●

the costs of advancing our manufacturing capabilities and securing manufacturing arrangements for pre-commercial and commercial production;

●

the level of product sales by us or our collaborators from any product candidates for which we obtain marketing approval in the future;

●

the costs of operating as a public company and maintaining adequate product, clinical trial, and directors’ and officers’ liability insurance coverage; and

●

the costs of establishing or contracting for sales, manufacturing, marketing, distribution, and other commercialization capabilities if we obtain regulatory approvals to market our product candidates.

Identifying potential product candidates and conducting preclinical studies and clinical trials is a time-consuming, expensive and uncertain process that takes years to complete. We may never generate the necessary data or results required to obtain marketing approval and achieve product sales. In addition, our product candidates, if approved, may not achieve commercial success. Our product revenues, if any, and any commercial milestone payments or royalty payments under our collaboration agreements, will be derived from sales of products that may not be commercially available for many years, if at all. Accordingly, we will need to continue to rely on additional financing and business development transactions to achieve our business objectives. Adequate additional financing may not be available to us on acceptable terms, or at all.

Until such time, if ever, as we can generate product revenues sufficient to achieve consistent profitability, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations, strategic alliances, and option and license arrangements. We do not have any committed external source of funds other than the amounts we are entitled to receive from our collaboration partners and licensors for reimbursement of certain research and development expenses, potential option exercises, the achievement of specified regulatory and commercial milestones, and royalty payments under our collaboration, and option and license agreements, as applicable. To the extent that we raise additional capital through the sale of equity or equity-linked securities, including convertible debt, our stockholders’ ownership interests will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our existing stockholders’ rights as holders of our common stock. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, obtaining additional capital, acquiring or divesting businesses, making capital expenditures or declaring dividends.

If we raise additional funds through collaborations, strategic alliances, or option and license arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Contractual Obligations

We enter into agreements in the normal course of business with clinical research organizations, contract manufacturing organizations, and institutions to license intellectual property. These contracts generally are cancelable at any time by us, upon 30 to 90 days prior written notice.

Our agreements to license intellectual property include potential milestone payments that are dependent upon the development of products using the intellectual property licensed under the agreements and contingent upon the achievement of clinical trial or regulatory approval milestones. We may also be required to pay annual maintenance fees or minimum amounts payable ranging from low-four digits to low five-digits depending upon the terms of the applicable agreement. In certain instances, we are also obligated to pay our licensors royalties based on sales of products, if approved, using the intellectual property licensed under the applicable agreement.

Table of Contents

We also have non-cancelable operating lease commitments arising from our leases of office and laboratory space at our facilities in Cambridge and Lexington, Massachusetts. For more information, refer to Note 6 to our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Off-Balance Sheet Arrangements

We did not have, during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined under applicable SEC rules.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risk related to changes in interest rates. We have policies requiring us to invest in high-quality issuers, limit our exposure to any individual issuer, and ensure adequate liquidity. Our primary exposure to market risk is interest rate sensitivity, which is affected by changes in the general level of U.S. interest rates, particularly because our investments, including cash equivalents, are in the form of money market funds and marketable securities and are invested in U.S. Treasury notes. Due to the short-term duration of our investment portfolio and the low risk profile of our investments, we believe an immediate 100 basis point change in interest rates would not have a material effect on the fair market value of our portfolio.

We are not currently exposed to market risk related to changes in foreign currency exchange rates; however, we may contract with vendors that are located in Asia and Europe in the future and may be subject to fluctuations in foreign currency rates at that time.

Inflation generally affects us by increasing our costs of labor, goods, and services. We do not believe that inflation had a material effect on our business, financial condition, or results of operations during the six months ended June 30, 2024.

ITEM 4. CONTROLS AND PROCEDURES

Management’s Evaluation of Disclosure Controls and Procedures

We maintain “disclosure controls and procedures,” as defined in Rules 13a-15(e) or 15d-15(e) under the Exchange Act of 1934, or Exchange Act, to mean controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Our disclosure controls and procedures include, without limitation, controls and other procedures designed to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2024. Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our principal executive officer and principal financial officer have concluded based upon the evaluation described above that, as of June 30, 2024, our disclosure controls and procedures were effective at the reasonable assurance level.

We continue to review and document our disclosure controls and procedures and may from time to time make changes aimed at enhancing their effectiveness and to ensure that our systems evolve with our business.

Changes in Internal Control over Financial Reporting

During the three months ended June 30, 2024, there have been no changes in our internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

On April 1, 2024, we granted to an executive a restricted stock unit award settleable for an aggregate of 105,000 shares of our common stock. This restricted stock unit award was granted outside of our 2015 Stock Option and Incentive Plan as an inducement material to such individual’s acceptance of an offer of employment with us in accordance with Nasdaq Listing Rule 5635(c)(4). We intend to file a registration statement on Form S-8 to register the shares of common stock underlying this award prior to the time at which the award becomes settleable.

ITEM 5.OTHER INFORMATION

None of our directors or officers adopted or terminated a Rule 10b5-1 trading arrangement or a non-Rule 10b5-1 trading arrangement (as such terms are defined in Items 408(a) and 408(c) of Regulation S-K, respectively) during the quarterly period covered by this report.

Voyager shall have the right to elect to co-Develop and co-Commercialize Products that are the subject of the GBA1 Program in the United States (the “Co-Co Option”) by providing Neurocrine with written notice of such election within [**] following the Co-Co Trigger Date. Upon such exercise, the Parties shall negotiate in good faith and enter into an agreement, which shall be based on terms and conditions substantially the same as those set forth in this Section 4.1 and otherwise consistent with this Agreement (each such agreement, a “Co-Co Agreement”), pursuant to which the Parties will jointly Develop and Commercialize and share equally in the Development Costs, Commercialization costs and profit or loss resulting from the Development and Commercialization of such Products in the United States (the “Co-Co Territory”). If Voyager exercises the Co-Co Option, (a) each Product in the GBA1 Program shall be designated a “Co-Co Product” hereunder and the GBA1 Program shall be designated the “Co-Co Program” hereunder, (b) the Parties will share equally in United States Development Costs incurred thereafter, and (c) Voyager will reimburse Neurocrine, as described in Sections 4.1.2(d), 4.1.3 and 7.3, for fifty percent (50%) of all Development Costs incurred by Neurocrine in connection with the Development of Products in the GBA1 Program prior to Voyager’s exercise of the Co- Co Option (the “Reimbursable Costs”); provided that following the first Change of Control of Voyager, Voyager will be obligated to pay interest on the Reimbursable Costs equal to [**]% per annum (paid by the same mechanism as the Reimbursable Costs) unless Voyager pays all of the Reimbursable Costs, without interest, within [**] after the later of (i) Voyager’s exercise of the Co-Co Option and (ii) effectiveness of such Change of Control. If Voyager does not exercise the Co-Co Option within [**] after the Co-Co Trigger Date, or if Voyager provides written notice to Neurocrine at any time prior to the Co-Co Trigger Date that it waives its right to exercise its Co-Co Option, then any accrued milestone payments would become payable by Neurocrine in accordance with Section 8.2(b) within [**].

1.3Section 8.2(b) of the Agreement is hereby deleted in its entirety and replaced with the following:

(b)If the Development Milestone described in Section 8.2.1(c) or any subsequent Development Milestone described in Section 8.2.1 is achieved prior to the date that is [**] after the Co-Co Trigger Date, then notwithstanding anything herein to the contrary, the corresponding Milestone Payment will not be due unless and until (i) the Co-Co Trigger Date occurs and Voyager does not exercise its Co-Co Option or (ii) Voyager waives its right to exercise the Co-Co Option as set forth in Section 4.1.1 (the date on which the foregoing (i) or (ii) occurs, the “Co-Co Expiration Date”). In such event, any unpaid Milestone Payment(s) for any Milestone Event(s) achieved prior to the Co-Co Expiration Date will be due within [**] after the Co-Co Expiration Date. If Voyager exercises its Co-Co Option, then notwithstanding anything herein to the contrary, Voyager shall be entitled to receive Milestone Payments only with respect to any Milestone Event that relates to the Territory outside the Co-Co Territory for so long as the GBA1 Program remains a Co-Co Program, as further provided below. If the Co-Co Agreement is terminated and the GBA1 Program is no longer a Co-Co Program, then the tables in Section 8.2.1 (for Development Milestones) and Section 8.2.3 (for Commercial Milestones) shall thereafter apply, but only with respect to Milestone Events achieved after termination of the Co-Co Agreement.

1.4Section 8.2(c) of the Agreement is hereby deleted in its entirety and replaced with the following:

(c)Subject to Section 8.2(b) above, and except as expressly set forth below, each Milestone Payment shall be deemed earned as of the achievement of the corresponding Milestone Event.

1.5The following is hereby added to the end of the first paragraph under the tables in Section 8.2.1 of the Agreement:

If Voyager does not exercise its Co-Co Option or waives its right to the Co-Co Option and thereafter any two (2) Products in the GBA1 Program achieves a Milestone Event as set forth in any of Sections 8.2.1(c)-(i) above for [**] as a first Indication, then notwithstanding anything herein to the contrary, such Milestone Event (and any prior Milestone Event not previously paid as further described in the following paragraph) shall be payable as a second Indication and the next Indication for such Product to achieve such Milestone Event shall be payable as a first Indication.

1.6Section 15.8 is hereby amended to update Voyager’s address in two places to 75 Hayden Avenue, Lexington, MA 02421.

1.7The Parties agree (a) to equally share Development Costs incurred by [**], and (b) that [**]. The Parties will also equally share the Out-of-Pocket Costs incurred by [**]. The Parties agree that if Development Costs incurred by the Parties in connection with [**] were to increase by more than [**], the Parties will seek approval of the JSC for such additional Development Costs.

2.MISCELLANEOUS

2.1Full Force and Effect. This Amendment amends the terms of the Agreement and is deemed incorporated into the Agreement. The provisions of the Agreement, as amended by this Amendment, remain in full force and effect.

2.2Entire Agreement. The Agreement and this Amendment constitute the entire agreement, both written and oral, between the Parties with respect to the subject matter hereof, and any and all prior agreements with respect to the subject matter hereof, either written or oral, expressed or implied, are superseded hereby, merged and canceled, and are null and void and of no effect.
