Item 7. 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 audited consolidated financial statements and related notes appearing elsewhere in this Annual Report on Form 10-K. Some of the information contained in this discussion and analysis or set forth elsewhere in this Annual Report on Form 10-K, including information with respect to our plans and strategy for our business, include forward-looking statements that involve risks, uncertainties, and assumptions. As a result of many factors, including those factors set forth in the section entitled “Risk Factors,” our actual results or outcomes, or the timing of our results or outcomes, could differ materially from the results or outcomes described in or implied by these forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those discussed in the section of this report entitled “Risk Factors.” You should carefully read the “Cautionary Note About Forward-Looking Statements” and “Risk Factors” sections of this Annual Report on Form 10-K to gain an understanding of the important factors that could cause actual results or outcomes, or the timing of our results or outcomes, to differ materially from the results or outcomes described below.

In this section, references to “we,” “our,” “us,” and “the Company” refer to post-merger Neurogene Inc. and our wholly owned subsidiary incorporated in the state of Nevada, also named Neurogene Inc. (“Neurogene OpCo”), unless otherwise indicated.

Overview

Despite recent scientific advances in genetics, most neurological diseases, particularly those with devastating consequences to patients, are left untreated. Conventional gene therapy is an attractive potential treatment approach for only a limited number of monogenic diseases due to the challenges caused by the complex biology of neurological diseases and by inherent variable transgene uptake and expression. We are a clinical-stage biotechnology company committed to overcoming these limitations and turning today’s complex devastating neurological diseases into treatable conditions. By harnessing our proprietary transgene regulation technology, EXACTTM (Expression Attenuation via Construct Tuning), we are building a robust and differentiated product portfolio of genetic medicines for rare neurological diseases with high unmet need not otherwise addressable by conventional gene therapy. Our EXACT approach leverages key scientific breakthroughs, including gene transfer technology, microRNA-based genetic circuits, and adeno-associated virus (“AAV”) delivery, and is designed to deliver therapeutic levels of transgene to key areas of the brain that underlie neurological disease pathology.

Our first clinical-stage program to utilize the EXACT platform is NGN-401, which is in development for the treatment of Rett syndrome, a disease with a patient population that has a significant unmet need, and that ultimately progresses to substantial neurological and physical impairment and premature death. We are conducting a Phase 1/2 open-label, multi-center clinical trial of NGN-401 gene therapy for the treatment of female patients with classic Rett syndrome that is assessing the safety, tolerability, and efficacy of NGN-401 at a dose of 1E15 vg. The trial is evaluating NGN-401 in eight pediatric participants ages 4-10 years old and in a pilot cohort of three participants ages 11 years and older. Clinical grade NGN-401 was manufactured at our manufacturing facility and is being used for dosing in the Phase 1/2 clinical trial. NGN-401 is delivered using a one-time intracerebroventricular (“ICV”) procedure, which we believe is the most suitable route of administration to achieve optimal biodistribution in key regions of the brain and other parts of the nervous system that underlie Rett syndrome pathophysiology.

The NGN-401 clinical trial has been initiated in three regions— the United States, the United Kingdom (“UK”) and Australia, after clearance of our Investigational New Drug (“IND”) application by the U.S. Food and Drug Administration (“FDA”) in January 2023, the clearance of the clinical trial application by the UK Medicines and Healthcare Products Regulatory Agency in January 2024, and acknowledgement from the Australian Therapeutic Goods Administration and approval from the Human Research Ethics Committee in May 2024. Participants have been dosed in all three regions.

In November 2024, we announced positive interim clinical data in participants receiving the 1E15 vg dose (n=4 for efficacy data; n=5 for safety data) from the Phase 1/2 clinical trial with a data cut-off date of October 17, 2024.

Table of Contents

The baseline demographics of the first five participants who received the 1E15 vg dose NGN-401 include:

*CGI-S = Clinician Global Impression-Severity

Consistent, concordant and durable improvements were observed as measured from baseline across multiple Rett syndrome clinical assessments. Participants also achieved meaningful gains of skills and developmental milestones in hand function, gross motor, and communication, all of which are core clinical domains of Rett syndrome. These gains of skills and developmental milestones are not expected to occur when compared and contextualized against the natural history of Rett syndrome. Additionally, objective improvements in autonomic function were recorded.

Consistent improvements were observed in the following:

*Each participant achieved a 2-point improvement or “much improved” from baseline.

We also announced safety and tolerability data from the Phase 1/2 clinical trial as of the data cut-off date of October 17, 2024. We believe that NGN-401 has been generally well-tolerated at the 1E15 vg dose. There continue to be no signs or symptoms indicating MeCP2 overexpression toxicity. We continue to expect to provide an update on safety and efficacy data in the second half of 2025, and therefore we do not plan to share interim data updates from the trial before that time.

In November 2024, we also announced that post-data cut-off date of October 17, 2024, the third participant receiving a 3E15 vg dose of NGN-401 (high dose) in the trial died following complications from a rare hyperinflammatory syndrome associated with systemic exposure to high doses of AAV. Hyperinflammatory syndromes can include hemophagocytic lymphohistiocytosis (“HLH”) and multisystem inflammatory syndrome. Based on research we conducted related to hyperinflammatory syndromes and AAV gene therapy, HLH has only been reported following doses of AAV that are generally in the 1E14 vg/kg range or higher. The 1E15 vg dose level we are moving forward in the trial translates into the E13 vg/kg range, and we are not aware of any case of HLH ever being reported at this dose level

In November 2024, we also shared that we had gained alignment with the FDA on our potency assay strategy and CMC scale-up planning for the program. We expect to share information about our registration study in the first half of 2025 and to announce additional Phase 1/2 clinical data in the second half of 2025.

In December 2024, we updated our Phase 1/2 protocol to remove the 3E15 vg dose from the trial, and we are currently enrolling participants. Despite our research related to hyperinflammatory syndromes and AAV gene therapy showing that HLH has only been reported following doses of systemic AAV that are higher than the 1E15 vg dose level, in an abundance of caution, we have incorporated into our protocol additional monitoring for markers using the HLH diagnostic criteria, such as ferritin, and a treatment algorithm. When administered early, this treatment algorithm has been used successfully to treat cases of HLH both in AAV gene therapy and other known causes of HLH.

In June 2024, we announced that NGN-401 was one of four sponsors selected by the Center for Biologics Evaluation and Research at the FDA to participate in the FDA’s Support for clinical Trials Advancing Rare disease Therapeutics (“START”) Pilot Program based on potential for clinical benefits and clinical development program readiness. As part of the START Program, we have opportunities for enhanced communications with the FDA, with the aim to further accelerate the pace of NGN-401’s development. These opportunities are designed to provide frequent advice and regular ad-hoc conversations to address product-specific development issues, including, but not limited to, clinical study design, choice of control group and fine-tuning the choice of patient population. In August 2024, we announced that NGN-401 also received Regenerative Medicine Advanced Therapy (“RMAT”) designation from the FDA. RMAT designation is granted for regenerative medicines intended to treat, modify, reverse, or cure a serious or life-threatening disease or condition, and with preliminary clinical evidence that indicates that the drug has the potential to address unmet medical needs. Benefits of the RMAT designation program include all the benefits of Fast Track and Breakthrough Therapy designation programs, including early and frequent communications with FDA senior managers, intensive guidance on efficient drug development and eligibility for an Accelerated Approval pathway and Priority Review.

We believe that our EXACT platform has broad applicability in complex neurological diseases not otherwise easily addressable by conventional gene therapy. In addition to our Rett syndrome program, we have multiple programs in the discovery stage.

In addition to NGN-401, we have also been pursuing a conventional gene therapy program in an ongoing Phase 1/2 clinical trial of NGN-101 for the treatment of CLN5 Batten disease. This patient population has a significant unmet need and experiences extensive neurological and physical impairment leading to blindness, loss of motor function and early mortality. Our Phase 1/2 clinical trial of NGN-101 was the first trial to assess the treatment of both neurodegenerative and ocular disease manifestations of Batten disease. In November 2024, we announced that we do not expect to move forward with the NGN-101 CLN5 Batten disease gene therapy program at this time. Given the rarity of the disease, continued investment in the program was predicated on alignment on a streamlined registrational pathway with the FDA. To support a streamlined pathway, we submitted an RMAT application to the FDA. Despite our belief that we met the standard of preliminary clinical evidence required to obtain an RMAT designation, the RMAT application was denied. We are currently evaluating options for the program.

We also established a fully operational current good manufacturing practices (“cGMP”) facility in Houston, Texas used to manufacture current and future product for research, toxicology and clinical studies. We believe that our in-house manufacturing capabilities better enable control of product quality and development timelines, strategic pipeline and financial flexibility, and clinical-to-commercial continuity.

Completion of the Reverse Merger and Pre-Closing Financing

On December 18, 2023, we completed our business combination with Neurogene OpCo (the “Closing”) in accordance with the terms of the Agreement and Plan of Merger, dated as of July 17, 2023 (the “Merger Agreement”), by and among the Company, Project North Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of the Company (“Merger Sub”), and Neurogene OpCo, pursuant to which, among other matters, Merger Sub merged with and into Neurogene OpCo, with Neurogene OpCo surviving as a wholly owned subsidiary of the Company (the “Reverse Merger”). In connection with the completion of the Reverse Merger, the Company changed its name from “Neoleukin Therapeutics, Inc.” (“Neoleukin”) to “Neurogene Inc.,” and the business conducted by the Company became primarily the business conducted by Neurogene OpCo. Immediately prior to Closing, the Company effected a 1-for-4 reverse stock split (the “Reverse Stock Split”). Unless noted otherwise, all references in this Annual Report on Form 10-K to share and per share amounts reflect the Reverse Stock Split.

Concurrently with the execution and delivery of the Merger Agreement, and in order to provide Neurogene OpCo with additional capital for its development programs, Neurogene OpCo entered into a subscription agreement (the “Subscription Agreement”) with certain investors named therein (the “Investors”), pursuant to which, subject to the terms and conditions of the Subscription Agreement, immediately prior to the effective time of the Reverse Merger, Neurogene OpCo issued and sold, and the Investors purchased, 2,792,206 shares of Neurogene OpCo common stock and 1,811,739 pre-funded warrants, exercisable for 1,811,739 shares of Neurogene OpCo common stock, at a purchase price of approximately $20.63 per share or $20.63 per warrant, for an aggregate purchase price of approximately $95.0 million (the “Pre-Closing Financing”).

See Item 8 of Part II “Financial Statements––Note 1 – Reverse Merger and Pre-Closing Financing” for additional information.

Closing of Private Placement

On November 5, 2024, we closed a private investment in public equity financing (the “November 2024 private placement”) in which we sold 1,835,000 shares of common stock at a price of $50.00 per share and, in lieu of shares of common stock, pre-funded warrants to purchase up to an aggregate of 2,165,042 shares of common stock, at a purchase price of $49.999 per pre-funded warrant, to certain institutional accredited investors. The pre-funded warrants are immediately exercisable until exercised in full at a price of $0.001 per share of common stock. The aggregate gross proceeds to the Company totaled $200.0 million. Net proceeds, net of commissions and other offering expenses, totaled $189.5 million.

Background

We were founded in 2018, and have devoted substantially all of our resources to conducting research and development activities (including with respect to the NGN-401 and NGN-101 programs) and undertaking preclinical studies, establishing our manufacturing facility, conducting clinical trials and the manufacturing of product used in our clinical trials and preclinical studies, business planning, developing and maintaining our intellectual property portfolio, hiring personnel, raising capital, and providing general and administrative support for these activities.

Since our inception, we have funded our operations primarily with outside capital (e.g., proceeds from the sale of preferred stock and common stock) and have raised aggregate net proceeds of approximately $521.9 million from these private placements. However, we have incurred significant recurring losses, including a net loss of $75.1 million and $36.3 million for the years ended December 31, 2024 and 2023, respectively. In addition, as of December 31, 2024, we had an accumulated deficit of $262.3 million and cash, cash equivalents and short-term investments totaling $312.4 million. In order to continue our operations, we must achieve profitable operations and/or obtain additional equity or debt financing. Until we achieve profitability, management plans to fund our operations and capital expenditures with cash on hand and the sale and issuance of securities. There can be no assurance that we will be successful in raising additional capital or that such capital, if available, will be on terms that are acceptable to us. If we are unable to raise sufficient additional capital, we may be compelled to consider actions such as reducing the scope of our operations and planned capital expenditures or selling certain assets, including intellectual property assets.

Our net losses may fluctuate significantly from quarter-to-quarter and year-to-year, depending on a variety of factors, including the timing, scope and results of our research and development activities. Management expects that our expenses and capital requirements will increase substantially in connection with our ongoing activities as we:

•advance the NGN-401 program through clinical development;

•advance discovery programs from preclinical development into and through clinical development;

100

Table of Contents

•seek regulatory approvals for any product candidates that successfully complete clinical trials;

•establish sales, marketing and distribution infrastructure to commercialize any approved product candidates;

•establish a commercialization infrastructure and scale up internal and external manufacturing and distribution capabilities to commercialize any product candidates for which we may obtain regulatory approval;

•expand clinical, scientific, management and administrative teams;

•maintain, expand, protect and enforce our intellectual property portfolio, including patents, trade secrets and know-how;

•implement operational, financial and management systems; and

•incur additional legal, accounting and other expenses related to operating as a public company.

We do not have any products approved for commercial sale and have not generated any commercial revenue from product sales. Our ability to generate product revenue sufficient to achieve and maintain profitability will depend upon the successful development and eventual commercialization of one or more of our product candidates, which we expect, if it ever occurs, will take many years. We expect to spend a significant amount in development and marketing costs prior to such time. We will therefore require substantial additional capital to develop our product candidates and support our continuing operations. We may never succeed in achieving regulatory and marketing approval for our product candidates. We may obtain unexpected results from our preclinical and clinical trials. In November 2024, we announced that the Company does not expect to move forward with the NGN-101 CLN5 Batten disease gene therapy program at this time. Given the rarity of the disease, continued investment in the program was predicated on alignment on a streamlined registrational pathway with the FDA. To support a streamlined pathway, we submitted an RMAT application to the FDA. Despite our belief that the application met the standard of preliminary clinical evidence required to obtain an RMAT designation, the RMAT application was denied. We are currently evaluating options for the program. We may in the future elect to discontinue, delay, or modify additional preclinical and clinical trials of our other product candidates. A change in the outcome of any of these variables with respect to the development of a product candidate could mean a significant change in the costs and timing associated with the development of that product candidate. Accordingly, until such time that we can generate a sufficient amount of revenue from product sales or other sources, if ever, management expects to finance our operations through private or public equity or debt financings, loans or other capital sources, which could include income from collaborations, partnerships or other marketing, distribution, licensing or other strategic arrangements with third parties, or from grants. However, we may be unable to raise additional capital from these sources on favorable terms, or at all. Our failure to obtain sufficient capital on acceptable terms when needed could have a material adverse effect on our business, results of operations or financial condition, including requiring us to delay, reduce or curtail our research, product development or future commercialization efforts. We may also be required to license rights to product candidates at an earlier stage of development or on less favorable terms than we would otherwise choose. Our management cannot provide assurance that we will ever generate positive cash flow from operating activities. See “Liquidity and Capital Resources.”

In December 2020, we entered into the Master Research Collaboration (“MCA”) with the University Court of the University of Edinburgh (the “University of Edinburgh”) to support our pipeline development and expansion, and to accelerate scientific innovation to continue to improve upon conventional gene therapy. In November 2023, the collaboration agreement was amended and extended through December 2026. The University of Edinburgh has a vibrant community of over 500 neuroscience researchers and is widely recognized as a preeminent center for neuroscience research, especially in areas of neurodegeneration and in neurodevelopmental disorders, such as Rett syndrome. For example, researchers currently in neuroscience centers at the University of Edinburgh conducted the seminal preclinical work for Rett syndrome, including discovery of the MeCP2 protein, its function as a transcriptional repressor, developing the first and most widely adopted animal model of Rett syndrome, demonstrating for the first time the reversibility of phenotypes in any neurodevelopmental disorder as well as the first ever preclinical gene therapy efforts in Rett syndrome. Under the terms of the agreement, we have the option to in-license product candidates from Dr. Stuart Cobb’s laboratory, where he has a dual appointment as a Professor in Translational Neuroscience at the Patrick Wild Centre and the Centre for Discovery Brain Sciences and serves as our Chief Scientific Officer. Dr. Cobb may be entitled to receive in the future a percentage of certain license-related payments from Neurogene to the University of Edinburgh in accordance with the University of Edinburgh’s standard policies for professor inventors.

Impact of Global Economic Events

Uncertainty in the global economy presents significant risks to our business. We are subject to continued risks and uncertainties related to the current macroeconomic environment, including high inflation, high interest rates, changes in foreign currency exchange rates, changes in trade policies, including tariffs or other trade restrictions or the threat of such actions, changes in domestic and global monetary and fiscal policy, recent bank failures, proposed or adopted federal U.S. legislation seeking to limit the provision of services in our sector by certain non-U.S. entities, geopolitical factors, including the ongoing conflicts between Russia and Ukraine and in the Middle East and the responses thereto, the impacts of climate change, and supply chain disruptions. While management is closely monitoring the impact of the current macroeconomic conditions on aspects of our business, including the impacts on our participants in our Phase 1/2 clinical trial, employees, suppliers, vendors and business partners, the ultimate extent of the direct and indirect impacts on our business remains highly uncertain and will depend on future developments and factors that continue to evolve. Most of these developments and factors are outside of our control and could exist for an extended period of time. Management will continue to evaluate the nature and extent of the potential impacts to our business, results of operations, liquidity and capital resources. For additional information, see the section entitled “Risk Factors.”

Components of Results of Operations

Revenue

We have no products approved for sale and have never generated any revenue from product sales.

We have generated licensing revenue from the recognition of upfront payments received under agreements with third parties for the disposition of legacy Neoleukin assets (the “December 2023 CVR Licensing Agreement” and the “April 2024 CVR Licensing Agreement”) that are related to the legacy Neoleukin business as part of the reverse merger. See Note 10, Commitments and Contingencies, for additional details regarding these licensing agreements.

Operating Expenses

Research and Development Expenses

Research and development expenses consist primarily of costs incurred in connection with the discovery and development of our product candidates. We expense research and development costs as incurred, including:

•expenses incurred to conduct the necessary discovery-stage laboratory work, preclinical studies and clinical trials required to obtain regulatory approval;

•acquired licenses and intellectual property that are accounted for as asset acquisitions and have no alternative future use;

•personnel expenses, including salaries, benefits and stock-based compensation expense for our employees engaged in research and development functions;

•costs of funding research performed by third parties, including pursuant to agreements with clinical research organizations (“CROs”) that conduct our clinical trials, as well as investigative sites, consultants and CROs that conduct our preclinical and nonclinical studies;

•expenses incurred under agreements with our third-party contract development and manufacturing organizations (“CDMOs”), as well as internal manufacturing scale-up expenses, including the cost of acquiring and manufacturing preclinical study and clinical trial materials;

•fees paid to consultants who assist with research and development activities;

•expenses related to regulatory activities, including filing fees paid to regulatory agencies; and

•allocated expenses for facility costs, including rent, utilities, depreciation and maintenance.

Before a product receives regulatory approval, we record upfront and milestone payments to third parties under licensing arrangements as expense, provided that there is no alternative future use of the rights in other research and development projects.

102

Table of Contents

Non-refundable prepayments for research and development costs that are paid in advance of performance are capitalized as a prepaid expense and amortized over the service period as the services are provided. Costs for certain development activities, such as outside research programs funded by us, are recognized based on an evaluation of the progress to completion of specific tasks with respect to their actual costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred, and are reflected in the financial statements as prepaid or accrued research and development expense as applicable.

We track outsourced development costs and other external research and development costs to specific product candidates on a program-by-program basis, including fees paid to CROs, CDMOs and research laboratories in connection with our preclinical development, process development, and clinical development activities. We also incur personnel and other operating expenses for research and development programs, which are presented in aggregate.

Research and development activities are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We expect our research and development expenses to increase significantly over the next several years as we increase personnel costs, including stock-based compensation, conduct clinical trials, including later-stage clinical trials for current and future product candidates, and prepare regulatory filings for our product candidates.

General and Administrative Expenses

General and administrative expenses consist primarily of personnel expenses, including salaries, benefits and stock-based compensation expense, for employees and consultants in executive, finance and accounting, legal, operations support, information technology and human resource functions. General and administrative expenses also include corporate facility costs not otherwise included in research and development expense, including rent, utilities, depreciation and maintenance, as well as legal fees related to intellectual property and corporate matters and fees for accounting and consulting services.

We expect that our general and administrative expense will increase in the future to support our continued research and development activities, potential commercialization efforts and increased costs of operating as a public company. These increases will likely include increased costs related to the hiring of additional personnel and fees to outside consultants, legal support and accountants, among other expenses. Additionally, we anticipate increased costs associated with being a public company, including expenses related to services associated with maintaining compliance with the requirements of Nasdaq and the SEC, insurance and investor relations costs. If any of our current or future product candidates obtains U.S. regulatory approval, we expect that we would incur significantly increased expenses associated with building a sales and marketing team, as well as an expanded regulatory and compliance function.

Interest Income

Interest income consists primarily of interest earned on our cash, cash equivalents and short-term investments. We expect our interest income to fluctuate depending on interest rates and the amount of cash that is invested.

Income Taxes

We assess our income tax positions and record tax benefits based upon management’s evaluation of the facts, circumstances, and information available at the reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained, we record the amount of tax benefit with a greater than 50 percent likelihood of being realized upon ultimate settlement with a taxing authority having full knowledge of all relevant information. For those income tax positions for which it is not more likely than not that a tax benefit will be sustained, no tax benefit is recognized in the financial statements.

Since inception, we have not recorded any income tax benefits for net operating losses (“NOLs”) or for our research and development tax credits, as we believe, based upon the weight of available evidence, that it is more likely than not that all of our NOLs and tax credits will not be realized. Accordingly, we have established a valuation allowance against such deferred tax assets for all periods since inception.

As of December 31, 2024, we had federal and state NOL carryforwards in the amount of $319.8 million and $39.6 million, respectively, which may be available to offset future taxable income. The state NOL carryforwards will begin to expire in 2038, unless previously utilized. Most federal NOL carryforwards were generated subsequent to January 1, 2018, and therefore are able to be carried forward indefinitely. As of December 31, 2024, we also had federal research tax credit and federal orphan drug tax credit carryforwards of $7.9 million and $4.8 million, respectively, which may be used to offset future tax liabilities. These tax and orphan drug credit carryforwards begin to expire in 2039 and 2043, respectively, unless previously utilized.

104

Table of Contents

Expenses related to the Rett syndrome program increased primarily due to a $5.2 million increase in clinical trial costs related to the Phase 1/2 clinical trial of NGN-401 and a $1.2 million increase in chemistry, manufacturing and controls costs, partially offset by a $0.3 million decrease in preclinical costs. The increase in expenses related to the Batten disease program was primarily driven by an increase of $0.7 million in clinical trial related expenses, partially offset by a decrease of $0.4 million in chemistry, manufacturing and controls costs. The increase in Early Discovery expenses was primarily driven by a $2.3 million increase in preclinical costs.

The increase in unallocated internal expenses was primarily driven by higher salaries, benefits, and stock-based compensation costs due to an increase in research and development headcount, as well as an increase in laboratory consumables expense related to chemistry, manufacturing and controls, partially offset by a decrease in wind-down expenses related to the Neoleukin reverse merger.

We expect that our research and development expenses will continue to increase for the foreseeable future as we advance our programs and product candidates into and through clinical development and, as we continue to develop additional product candidates, build our manufacturing capabilities and develop our EXACT technology.

General and Administrative Expenses

The following table summarizes our general and administrative expenses for the periods indicated:

(in thousands)Year Ended December 31,
20242023Change
General and administrative specific expenses:
Personnel-related$8,098$5,923$2,175

Office-related2,5342362,298
Other3,6102,2031,407
Total general and administrative expenses$22,613$11,189$11,424

General and administrative expenses were $22.6 million for the year ended December 31, 2024 as compared to $11.2 million for the year ended December 31, 2023. The increase was primarily attributable to: (i) an increase of approximately $2.2 million in personnel-related expenses driven by an increase in headcount to support business operations, (ii) an increase of approximately $3.3 million in stock-based compensation expense, driven by an increase in headcount as well as an increase in grant date fair value of awards resulting from an increase in the stock price, (iii) an increase of approximately $2.3 million in professional services and consulting fees associated with the transition from a private company to a public company, (iv) an increase of office-related expense of approximately $2.3 million, which was primarily attributable to rent associated with the Company’s assumption of legacy Neoleukin facilities (the Eastlake Lease and Blaine Lease), and (v) an increase in other costs of approximately $1.4 million attributable to approximately $2.2 million of corporate related expenses and market research costs. These expenses were partially offset by a business email compromise attack by a third party in the prior period, which resulted in the diversion of payments totaling approximately $0.9 million to a fraudulent bank account. As of December 31, 2023, we recovered approximately $0.5 million of the diverted funds. Subsequent to December 31, 2023, we have additionally recovered approximately $0.3 million of the diverted funds.

We anticipate that our general and administrative expenses will increase in the future to support increased research and development activities.

Interest Income

Interest income increased by $5.5 million for the year ended December 31, 2024, as compared to the year ended December 31, 2023. The increase was primarily due to a significant increase in the amount of our cash, cash equivalents and short-term investments which was partially offset by a moderate decrease in interest rates.

Other income decreased by $15.8 million for the year ended December 31, 2024, as compared to the year ended December 31, 2023. In the current year, we recorded sublease income of approximately $0.6 million associated with the Eastlake Lease assumed after the Reverse Merger closed. In the prior year, we recorded a bargain purchase gain of approximately $16.4 million in connection with the Closing. The fair value of Neoleukin’s net assets acquired at the Closing exceeded the total consideration transferred after the fair value allocation by approximately $17.6 million. $1.3 million of the difference was recorded as a contingent consideration liability for payments that are probable and estimable under the CVR Agreement, and the remaining $16.4 million was recognized as a bargain purchase gain.

Other Expenses

Other expenses increased by $1.5 million for the year ended December 31, 2024, as compared to the year ended December 31, 2023. The increase was primarily due to (i) an approximately $0.8 million accrual of contingent consideration liabilities related to the Intellectual Property CVR (as defined in Note 10, Commitments and Contingencies) in connection with the December 2023 Licensing Agreement and the April 2024 Licensing Agreement and (ii) an approximately $0.4 million accrual of a contingent consideration liability related to the Sales Tax CVR for an anticipated sales tax refund from Washington state and (iii) an approximate $0.4 million accrual to the contingent consideration liability related to the Intellectual Property CVR to offset permitted deductions under the CVR agreement.

Liquidity and Capital Resources

Sources of Liquidity

Since inception, we have not generated any revenue from product sales and have incurred significant operating losses and negative cash flows from our operations. We expect to continue to incur significant expenses and operating losses for the foreseeable future as we advance the clinical development of our product candidates. We expect that our research and development and general and administrative costs will continue to increase significantly, including in connection with conducting clinical trials and manufacturing for our product candidates to support commercialization and providing general and administrative support for our operations, including the costs associated with operating as a public company. As a result, we will need additional capital to fund our operations, which we may obtain from additional equity or debt financings, collaborations, licensing arrangements or other sources. We believe that our existing capital resources will be sufficient to fund our operations through at least 12 months following the filing date of this Form 10-K. See the section entitled “Risk Factors” for additional risks associated with our substantial capital requirements.

As of December 31, 2024, we had cash, cash equivalents and short-term investments totaling $312.4 million. Since inception and through the issuance of these financial statements, we have funded our operations primarily through private placements of convertible preferred stock and common stock for net proceeds of approximately $521.9 million.

Future Capital Requirements

In order to complete the development of our product candidates and to build the sales, marketing and distribution infrastructure that management believes will be necessary to commercialize product candidates, if approved, we will require substantial additional capital. Accordingly, until such time as we can generate a sufficient amount of revenue from product sales or other sources, if ever, management expects to seek to raise any necessary additional capital through private or public equity or debt financings, loans or other capital sources, which could include income from collaborations, partnerships or other marketing, distribution, licensing or other strategic arrangements with third parties, or from grants. To the extent that we raise additional capital through equity financings or convertible debt securities, the ownership interest of our stockholders will be or could be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. Debt financing and equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, including restricting our operations and limiting our ability to incur liens, issue additional debt, pay dividends, repurchase our own common stock, make certain investments or engage in merger, consolidation, licensing, or asset sale transactions. If we raise capital through collaborations, partnerships, and other similar arrangements with third parties, we may be required to grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves. We may be unable to raise additional capital from these sources on favorable terms, or at all. Our ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and the recent disruptions to, and volatility in, the credit and financial markets in the United States and worldwide resulting from macroeconomic conditions, geopolitical instability, government regulation and otherwise. The failure to obtain sufficient capital on acceptable terms when needed could have a material adverse effect on our business, results of operations or financial condition, including by requiring us to delay, reduce or curtail our research, product development or future commercialization efforts. We may also be required to license rights to product candidates at an earlier stage of development or on less favorable terms than we would otherwise choose. Management cannot provide assurance that we will ever generate positive cash flow from operating activities.

In order to continue our operations, we must achieve profitable operations and/or obtain additional equity or debt financing. Until we achieve profitability, management plans to fund our operations and capital expenditures with cash on hand and the sale and issuance of securities. We may not be successful in raising additional capital and such capital, if available, may not be on terms that are acceptable to us.

We have incurred, and expect to continue to incur, additional costs associated with operating as a public company. In addition, we anticipate that we will need substantial additional funding in connection with our continuing operations. Management bases its projections of operating capital requirements on our current operating plan, which includes several assumptions that may prove to be incorrect, and we may use all of our available capital resources sooner than management expects.

Because of the numerous risks and uncertainties associated with research, development and commercialization of product candidates, we are unable to estimate the exact amount and timing of our capital requirements. Our future funding requirements will depend on many factors, including:

•the scope, timing, progress, results, and costs of researching and developing genetic medicines, and conducting larger and later-stage clinical trials;

•the scope, timing, progress, results, and costs of researching and developing other product candidates that we may pursue;

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

•the costs of future activities, including product sales, medical affairs, marketing, manufacturing, and distribution, for any of our product candidates for which we receive marketing approval;

•the costs of manufacturing commercial-grade products and sufficient inventory to support commercial launch;

•the revenue, if any, received from commercial sale of our products, should any of our product candidates receive marketing approval;

•the cost and timing of attracting, hiring, and retaining skilled personnel to support our operations and continued growth;

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

107

Table of Contents

•Our ability to establish, maintain, and derive value from collaborations, partnerships or other marketing, distribution, licensing, or other strategic arrangements with third parties on favorable terms, if at all;

•the extent to which we acquire or in-license other product candidates and technologies, if any; and

•the costs associated with operating as a public company.

A change in the outcome of any of these or other factors with respect to the development of any of our product candidates could significantly change the costs and timing associated with the development of that product candidate. Furthermore, our operating plans may change in the future, and we may need additional capital to meet the capital requirements associated with such operating plans.

Research and Development and Manufacturing Agreements

We enter into agreements with certain vendors for the provision of goods and services, which includes manufacturing services with contract development and manufacturing organizations and development and clinical trial services with CROs. These agreements may include certain provisions for purchase obligations and termination obligations that could require payments for the cancellation of committed purchase obligations or for early termination of the agreements. The amount of the cancellation or termination payments vary and are based on the timing of the cancellation or termination and the specific terms of the agreement. These obligations and commitments are not presented separately.

License and Collaboration Agreements

License Agreement with The University of Edinburgh

In December 2020, we entered into the MCA with University of Edinburgh. Under the MCA, we and the University of Edinburgh agreed to collaborate on certain research and development projects (“Projects”), and we agreed to provide funding for such Projects for a 40-month initial term, which term was extended in November 2023 for an additional 33 months and may be further extended by mutual agreement. In exchange for such funding, the University of Edinburgh granted us the option to exclusively license any intellectual property arising from such Projects. Under the MCA, we are obligated to pay semi-annual installment payments relating to funding of costs for personnel and lab consumables for the 40-month period. Either party may terminate the MCA for convenience upon 90 days’ notice. If we terminate the MCA, we would be responsible for all non-cancellable costs and commitments related to any particular Project and any and all funding costs for any person working on such Project.

110

Table of Contents

In March 2022, we exercised our option through the collaboration under the MCA, and entered into a License Agreement (the “March 2022 Edinburgh License Agreement”) with University of Edinburgh, pursuant to which we licensed certain patents and know-how related to the EXACT technology and optimized MECP2 cassettes on an exclusive basis. Under the March 2022 Edinburgh License Agreement, we obtained an exclusive, worldwide license to the licensed patents to develop, manufacture, supply, sell, and commercialize any products that utilize the licensed patents (the “Licensed Products”) in exchange for low single-digit percentage royalties on future commercial net sales of the Licensed Products. Royalties are payable on a Licensed Product-by-Licensed Product and country-by-country basis until the later of the expiration of the last licensed patent covering such Licensed Product in the country where the Licensed Product is sold, or, if no licensed patent exists or has expired in such country, then ten years from first commercial sale of such Licensed Product in such country (the “Royalty Term”). The term of the March 2022 Edinburgh License Agreement continues until the end of the Royalty Term and the expiration of all of the payment obligation thereunder. We may terminate the March 2022 Edinburgh License Agreement for convenience upon 90 days’ notice. In connection with the license, we are also obligated to pay the University of Edinburgh up to $5.3 million in regulatory-related milestones and up to $25.0 million in sales-related milestones based on annual net sales of Licensed Products in excess of defined thresholds.

License Agreement with Virovek

In September 2020, we entered into a Non-Exclusive License Agreement with Virovek, Inc., pursuant to which we have a license to use certain patents and know-how on a non-exclusive basis related to our baculovirus process in exchange for low single-digit percentage royalties on future commercial net sales of each product using the baculovirus process, development milestone payments of up to $0.2 million in the aggregate, and a nonrefundable annual license fee. This agreement continues until the later of (a) the expiration of the last to expire patent right that covers the manufacture, use, offer for sale, sale, importation, export or supply of any licensed product, (b) ten years after the first commercial sale of any licensed product, or (c) the expiration of all regulatory or market exclusivities. We may terminate this agreement for convenience upon 60 days’ notice.

License Agreement with Sigma-Aldrich Co

In January 2023, we entered into a Non-Exclusive License Agreement with Sigma-Aldrich Co. LLC, pursuant to which we have a license to certain patents and know-how on a non-exclusive basis related to certain cell lines used in our baculovirus process in exchange for a small annual fee on a product-by-product basis, payable once the first product candidate enters the clinic. In addition, on a product-by-product basis, we are obligated to pay up to $2.5 million in the aggregate for development-related milestones. This agreement remains in force for as long as we continue to possess and use the licensed technology. We may terminate this agreement for convenience upon 60 days’ notice.

License Agreement with Stanford

In August 2024, we entered into a Nonexclusive License Agreement with the Board of Trustees of Leland Stanford Junior University (the “Stanford License Agreement”) to license, on a non-exclusive basis, certain biological materials used in the manufacturing process of our product candidates, including NGN-401. Over the 10-year term of the Stanford License Agreement, we are obligated to pay up to $0.5 million in licensing fees. We may terminate this agreement for convenience upon 30 days’ notice.

Off-Balance Sheet Arrangements

We currently do not have, and did not have during the periods presented, any off-balance sheet arrangements, as defined in the rules and regulations of the SEC.

Critical Accounting Policies and Significant Judgments and Estimates

Our financial statements are prepared in accordance with U.S. GAAP. The preparation of the financial statements and related disclosures requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, costs and expenses, and the disclosure of contingent assets and liabilities in our financial statements. We base our estimates on historical experience, known trends and events and various other factors that management believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Management evaluates estimates and assumptions on a periodic basis. Our actual results may differ from these estimates.

111

Table of Contents

While our significant accounting policies are described in more detail in Note 3 to the financial statements appearing elsewhere in this Form 10-K, management believes that the following accounting policies are critical to understanding our historical and future performance, as the policies relate to the more significant areas involving management’s judgments and estimates used in the preparation of the financial statements.

Research and Development Expenses

Research and development expenses consist primarily of costs incurred in connection with the development of our product candidates. We expense research and development costs as incurred.

These costs include, but are not limited to, employee-related expenses, including salaries, benefits and travel of research and development personnel, facilities, supplies, rent, insurance, stock-based compensation, depreciation and external expenses incurred under agreements with contract research organizations and investigative sites that conduct preclinical and clinical studies and manufacture the drug product for our preclinical and clinical activities and other costs associated with preclinical activities.

Before a product receives regulatory approval, we record upfront and milestone payments to third parties under licensing arrangements as expense, provided that there is no alternative future use of the rights in other research and developments projects.

We accrue expenses for preclinical studies and clinical trial activities performed by our vendors based upon estimates of the proportion of work completed. We determine the estimates by reviewing contracts, vendor agreements and purchase orders, and through discussions with our internal clinical personnel and external service providers as to the progress or stage of completion of trials or services and the agreed-upon fee to be paid for such services. However, actual costs and timing of clinical trials are highly uncertain, subject to risks and may change depending upon a number of factors, including our clinical development plan. There can be judgment involved in measuring the research and development expenses to be recognized in a particular period. In some cases, expense is recorded using an underlying assumption of the progress to completion of specific activities. For example, costs may be recognized based on the passage of time for activities that span reporting periods. If the provision of services is not linear then this assumption could impact the amount of expense recognized. The level of judgment varies based on the nature of the services being performed and the underlying support obtained. For some activities, such as for certain clinical trials, expense is recorded based on information obtained from vendors as an intermediary to those performing the underlying services, such as contract research organizations. These estimates are inherently more judgmental since the quality and availability of the underlying data may vary. We do not need to make significant estimates where costs incurred are supported by invoices or reports of costs incurred are obtained from a vendor that is directly performing the underlying services, such as a consultant or contract manufacturing organization.

We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on facts and circumstances known at that time. If the actual timing of the performance of services or the level of effort varies from the estimate, we will adjust the accrual accordingly. Nonrefundable advance payments for goods and services, including fees for clinical trial expenses, process development or manufacturing and distribution of clinical supplies that will be used in future research and development activities, are deferred and recognized as expense in the period that the related goods are consumed or services are performed.

In-process research and development (“IPR&D”) that is acquired through licensing arrangements and accounted for as asset acquisitions are expensed immediately and within research and development expenses if the IPR&D has no alternative future use.

Stock-Based Compensation

We account for stock options granted to employees and non-employees at fair value, which is measured using Black-Scholes Option pricing model. The fair value measurement date for employee awards is generally the date of grant. We recognize stock-based compensation expense over the requisite service period of the individual grant, generally equal to the vesting period and use the straight-line method to recognize stock-based compensation.

Our policy is to account for forfeitures of stock-based awards when they occur in accordance with ASC 718, Compensation—Stock Compensation. We reverse compensation cost previously recognized, in the period the award is forfeited, for an award that is forfeited before completion of the requisite service period.

112

Table of Contents

We utilize the Black-Scholes option-pricing model, which incorporates assumptions and estimates, to value these options. Estimates and assumptions impacting the fair value measurement include the fair value per share of the underlying stock issuable upon exercise of the options, life of the options, risk-free interest rate, expected dividend yield and expected volatility from peer public companies of the price of the underlying stock.

Estimating the Fair Value of Common Stock

Prior to the Merger, we were required to estimate the fair value of the common stock underlying our stock-based awards when performing the fair value calculations using the Black-Scholes option pricing model. Because our common stock was not publicly traded, the fair value of the common stock underlying our stock options was determined on each grant date by our board of directors, with input from management, considering our most recently available third-party valuation of common shares. Following the Merger, the fair value of our common stock is based on the closing stock price on the date of grant as reported on Nasdaq.

Prior to the Merger, the third-party valuations of our common stock were performed using methodologies, approaches and assumptions consistent with the American Institute of Certified Public Accountants, Audit and Accounting Practice Aid Series: Valuation of Privately Held Company Equity Securities Issued as Compensation. In addition, our board of directors considered various objective and subjective factors to estimate the estimated fair value of our common stock, including:

•contemporaneous valuations of our common stock performed by independent third-party specialists;

•prices of our convertible preferred stock sold to outside investors in arm’s length transactions, and the rights, preferences and privileges of our convertible preferred stock as compared to those of our common stock, including the liquidation preferences of our convertible preferred stock;

•estimated value of each security both outstanding and anticipated;

•anticipated capital structure, which will directly impact the value of the currently outstanding securities;

•actual results of operations and financial position;

•the status of our research and development efforts;

•the composition of, and changes to, our management team and board of directors;

•the lack of marketability and liquidity of our common stock as a private company;

•our stage of development and business strategy and the material risks related to our business and industry;

•general external market conditions affecting the life sciences and biotechnology industry sectors;

•U.S. and global economic conditions;

•the likelihood of achieving a liquidity event for the holders of our common stock, such as an initial public offering or a sale of our company, given prevailing market conditions; and

•the market value and volatility of comparable companies.

In determining the estimated fair value of our common stock, our board of directors considered the subjective factors discussed above in conjunction with then available valuations of our common stock that were prepared by a third-party. Our board of directors, with the assistance of third parties, determined the valuation of our common stock was $18.39 per share as of January 13, 2023 and such valuation by the board of directors was used for the purposes of determining the stock-based compensation expense for the year ended December 31, 2023.
