Current report
We have initiated the build-out of our sales and marketing infrastructure and may enter into arrangements with third parties for commercialization of DNL310 and future product candidates. There are risks involved with both establishing our own commercial capabilities and entering into arrangements with third parties to perform these services. For example, recruiting and training a sales force or reimbursement specialists is expensive and time consuming and could delay any product launch. If the commercial launch of a product candidate for which we recruit a sales force and establish marketing and other commercialization capabilities is delayed or does not occur for any reason, we would have prematurely or unnecessarily incurred these commercialization expenses. This may be costly, and our investment would be lost if we cannot retain or reposition our commercialization personnel.

Previous report
We have a diversified portfolio with numerous programs at various stages of research, discovery, preclinical, and clinical development. These programs require significant capital investment. We seek to maintain a process of prioritization and resource allocation to maintain an optimal balance between aggressively advancing lead programs and replenishing our portfolio. We regularly review the programs in our portfolio, and terminate those programs which do not meet our development criteria, which we have done a number of times in the past.
Previous report
Public health outbreaks, such as epidemics or pandemics, may significantly disrupt our business. Such outbreaks pose the risk that we or our employees, contractors, suppliers, and other partners may be prevented from conducting business activities for an indefinite period of time due to the spread of the disease, due to shutdowns that may be requested or mandated by federal, state, and local governmental authorities or certain employers, or due to the economic consequences associated with the pandemic. Business disruptions could include disruptions or restrictions on our ability to travel, as well as temporary closures of our facilities and the facilities of our partners, clinical trial sites, service providers, suppliers, or contract manufacturers. For example, the COVID-19 pandemic caused a temporary disruption in our ability to recruit participants for our clinical trials in the calendar year 2020 and the first quarter of 2021. While it is not possible to predict whether another pandemic, epidemic, or infectious disease outbreak similar to COVID-19 will materialize, any measures taken by governments and local authorities in response to such future health crises have the potential to disrupt and delay the initiation of new clinical trials, the progress of our ongoing clinical trials and our preclinical activities, and potentially the manufacture or shipment of both drug substance and finished drug product of our product candidates for preclinical testing and clinical trials, as well as adversely impact our business, financial condition, or operating results.
Previous report
The continued impact of the COVID-19 pandemic may materially and adversely affect our business, operations and financial condition.
Previous report
On May 11, 2023, the federal government ended the COVID-19 public health emergency, which ended a number of temporary changes made to federally funded programs, while some remain in effect. The full impact of the termination of the public health emergency on the FDA and other regulatory policies and operations remains unclear. In response to the COVID-19 pandemic, we implemented policies that enabled some of our employees to work remotely, which policies may continue for an indefinite period. Due to telecommuting patterns, modified work schedules, and enhanced safety protocols, our laboratory operations have at times and may again operate with decreased efficiency. Furthermore, our clinical trial sites for our clinical studies were impacted by the COVID-19 pandemic: in 2020, we experienced a pause in enrollment in our BIIB122/DNL151 Phase 1 and Phase 1b trials, our DNL343 Phase 1 and Phase 2/3 trials, and our ETV:IDS program observational biomarker study, and we have subsequently experienced certain delays in patient enrollment.
Previous report
The FDA issued a number of COVID-19 related guidance documents for manufacturers and clinical trial sponsors in 2020 and 2021, many of which have expired or were withdrawn with the expiration of the COVID-19 public health emergency in May 2023, although some COVID-19 related guidance documents remain in effect. Should the FDA issue additional guidance that mandates material changes to our clinical trials in response to a pandemic or other public health outbreaks, the costs of such clinical trials may increase. To the extent we experience any ongoing pandemic disruptions or other public health emergencies, potential impacts to our business may include delays or difficulties in enrolling patients, difficulties interpreting data impacted by trial disruptions, supply chain issues, staffing shortages, and disruptions to the operations of our service providers, any of which could have a material adverse effect on our business and clinical development plans.
Previous report
To the extent another pandemic or other public health outbreak adversely affects our business, operations and financial condition in the future, it may also have the effect of heightening many of the risks described in this “Risk Factors” section.
Previous report
•our competitors may develop platform technologies to deliver large molecule therapeutics across the BBB that render our platform technology obsolete or less attractive;
Previous report
We may not be successful in our efforts to further develop our BBB platform technology and current product candidates. We are not permitted to market or promote any of our product candidates before we receive regulatory approval from the FDA or comparable foreign regulatory authorities, and we may never receive such regulatory approval for any of our product candidates. Our product candidates are in the early stages of development and will require significant additional clinical development, management of preclinical, clinical, and manufacturing activities, regulatory approval, adequate manufacturing supply, a commercial organization, and significant marketing efforts before we generate any revenue from product sales, if at all.
Previous report
If any of our product candidates successfully complete clinical trials, we generally plan to seek regulatory approval to market our product candidates in the United States, the European Union ("EU"), and in additional foreign countries where we believe there is a viable commercial opportunity. We have never commenced, compiled, or submitted an application seeking regulatory approval to market any product candidate, and may never receive such regulatory approval even if a product candidate successfully completes clinical trials, which would adversely affect our viability. To obtain regulatory approval in countries outside the United States, we must comply with numerous and varying regulatory requirements of such other countries regarding safety, efficacy or potency, purity, chemistry, manufacturing and controls, clinical trials, commercial sales, pricing, and distribution of our product candidates. We may also rely on our collaborators or partners to conduct the required activities to support an application for regulatory approval, and to seek approval, for one or more of our product candidates. We cannot be sure that our collaborators or partners will conduct these activities or do so within the time frame we desire. Even if we (or our collaborators or partners) are successful in obtaining approval in one jurisdiction, we cannot ensure that we will obtain approval in any other jurisdictions. If we are unable to obtain approval for our product candidates in multiple jurisdictions, our revenue, business, financial condition, results of operations and growth prospects could be negatively affected.
Previous report
Even if we receive regulatory approval to market any of our product candidates, whether for the treatment of neurodegenerative and lysosomal storage diseases or other diseases, we cannot assure you that any such product candidate will be successfully commercialized, widely accepted in the marketplace or more effective than other commercially available alternatives.

Previous report
We do not have a sales or marketing infrastructure and have no experience in the sale, marketing, or distribution of pharmaceutical products. To achieve commercial success for any approved product for which we retain sales and marketing responsibilities, we must either develop a sales and marketing organization or outsource these functions to third parties. In the future, we may choose to build a focused sales, marketing, and commercial support infrastructure to sell, or participate in sales activities with our collaborators for, some of our product candidates if and when they are approved.
Previous report
Drug-related side effects could affect patient recruitment, the ability of enrolled patients to complete the trial, and/or result in potential product liability claims. We are required to maintain product liability insurance pursuant to certain of our license agreements. We may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses due to liability. A successful product liability claim or series of claims brought against us could cause our stock price to decline and, if judgments exceed our insurance coverage, could adversely affect our results of operations and business. In addition, regardless of merit or eventual outcome, product liability claims may result in impairment of our business reputation, withdrawal of clinical trial participants, costs due to related litigation, distraction of management’s attention from our primary business, initiation of investigations by regulators, substantial monetary awards to patients or other claimants, the inability to commercialize our product candidates, and decreased demand for our product candidates, if approved for commercial sale.
Previous report
We may incur liabilities, expenses, costs, and other operational losses under the GDPR and UK GDPR as well as privacy and data protection laws of Switzerland, the United Kingdom, and applicable EU member states. We may find it necessary or appropriate to make additional changes to the ways we or our service providers collect, disclose, transfer, and otherwise process data within the EEA, Switzerland, and the UK, and to our related policies and practices. This may be onerous and may interrupt or delay our development activities, and adversely affect our business, financial condition, results of operations and prospects.
Previous report
Inadequate funding for the FDA, the SEC, and other government agencies could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in a timely manner, or otherwise prevent those agencies from performing normal business functions on which the operation of our business may rely, which could negatively impact our business.
Previous report
•collaborations may be terminated in their entirety or with respect to certain product candidates or technologies and, if so terminated, may result in a need for additional capital to pursue further development or commercialization of the applicable product candidates or technologies, including our BBB platform technology; and
Previous report
•collaboration agreements may not lead to development or commercialization of product candidates in the most efficient manner or at all. If a present or future collaborator of ours were to be involved in a business combination, the continued pursuit and emphasis on our development or commercialization program under such collaboration could be delayed, diminished, or terminated.
Previous report
•challenges enforcing our contractual and intellectual property rights, especially in those non-U.S. countries that do not offer the same level of intellectual property protection as the United States;
Previous report
The rules dealing with U.S. federal, state and local income taxation are constantly under review by legislators and by the Internal Revenue Service and the U.S. Treasury Department. Changes to tax laws (which changes may have retroactive application) have occurred and are likely to continue to occur in the future, which could adversely affect our shareholders. For example, in August 2022, the United States enacted the Inflation Reduction Act, which implemented a 15% minimum tax on book income for certain companies and introduced a 1% excise tax on stock buybacks. Changes in tax laws, regulation, or enforcement could adversely affect our stockholders or require us to implement changes to minimize increases in our tax liability.

Previous report
In January 2020, we sold 9.0 million shares of common stock in an underwritten follow-on offering pursuant to a shelf registration statement filed in March 2019 and, in October 2022, we sold 11.9 million shares of common stock in an underwritten public offering pursuant to a second shelf registration statement filed in February 2022. Also in February 2022, we entered into an equity distribution agreement with Goldman Sachs & Co. LLC, SVB Securities LLC, and Cantor Fitzgerald & Co., as sales agents, to establish an at-the-market facility pursuant to which we may offer and sell from time to time up to $400.0 million in shares of our common stock. On February 27, 2024, we announced a strategic private offering transaction in which we sold 3,244,689 shares of our common stock and pre-funded warrants to purchase 26,046,065 shares of our common stock, resulting in net proceeds of approximately $499.3 million.

We have invested significant financial resources in research and development activities, including for our preclinical and clinical product candidates and our TV platform. We do not expect to generate revenue from product sales for several years, if at all. The amount of our future net losses will depend, in part, on the level of our future expenditures and revenue. Moreover, our net losses may fluctuate significantly from quarter to quarter and year to year, such that a period-to-period comparison of our results of operations may not be a good indication of our future performance.

Our operations have required substantial amounts of cash since inception. We currently fund our operations primarily withthe proceeds from our follow-on offering completed in October 2022, payments received from our collaboration agreements with Biogen, Sanofi, and Takeda, and a strategic private offering transaction completed in February 2024. We have a diversified portfolio with numerous programs at various stages of research, discovery, preclinical, and clinical development. Developing our product candidates is expensive, and we expect to continue to spend substa ntial amounts as we fund our early-stage research projects, and continue to advance our programs through preclinical and clinical development. Even if we are successful in developing our product candidates, obtaining regulatory approvals and launching and commercializing any product candidate will require substantial additional funding.

As of September 30, 2024, we had $1.28 billion in cash, cash equivalents and marketable securities. We believe that our existing cash, cash equivalents and marketable securities will be sufficient to fund our projected operations through at least the next twelve months. Our estimate as to how long we expect our existing cash, cash equivalents, and marketable securities to be available to fund our operations is based on assumptions that may be proven inaccurate, and we could use our available capital resources sooner than we currently expect. Changing circumstances, some of which may be beyond our control, such as recent bank failures, geopolitical uncertainty, rising inflation or interest rates, or a perceived or actual economic downturn, may cause us to increase our spending significantly faster than we currently anticipate, and we may need to seek additional funds sooner than planned. We may also need to raise additional funds sooner than we anticipate if we choose to expand more rapidly than we presently anticipate.

Due to the significant resources required for the development of our programs, and depending on our ability to access capital, we must prioritize development of certain product candidates. Moreover, we may expend our limited resources on programs that do not yield a successful product candidate and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success.

Previous wording
Due to the significant resources required for the development of our programs, we must focus our programs on specific diseases and disease pathways and decide which product candidates to pursue and advance and the amount of resources to allocate to each. Our decisions concerning the allocation of research, development, collaboration, management, and financial resources toward particular product candidates or therapeutic areas may not lead to the development of any viable commercial product and may divert resources away from better opportunities. Similarly, our potential decisions to delay, terminate, divest, or collaborate with third parties in respect of certain programs may subsequently also prove to be suboptimal and could cause us to miss valuable opportunities. If we make incorrect determinations regarding the viability or market potential of any of our programs or product candidates or misread trends in the biopharmaceutical industry, in particular for neurodegenerative and lysosomal storage diseases, our business, financial condition, results of operations, and growth prospects could be materially adversely affected. As a result, we may fail to capitalize on viable commercial products or profitable market opportunities, be required to forgo or delay pursuit of opportunities with other product candidates or other diseases and disease pathways that may later prove to have greater commercial potential than those we choose to pursue, or relinquish valuable rights to such product candidates through collaboration, licensing, or other royalty arrangements in cases in which it would have been advantageous for us to invest additional resources to retain sole development and commercialization rights.

We have never completed a clinical development program. We have previously discontinued the development of certain molecules prior to completion of preclinical development because we did not believe theymet our criteria for potential clinical success. Further, we cannot be certain that any of our product candidates will be successful in clinical trials. For instance, in August 2023, together with our collaboration partner Takeda, we discontinued development of TAK-920/DNL919 (ATV:TREM2) in Alzheimer’s disease, based on data from the Phase 1 study and the rapidly evolving treatment landscape and shifted our efforts to exploring back-up molecules. We may in the future advance product candidates into clinical trials and terminate such trials prior to their completion.

One of our strategies is to identify and pursue clinical development of additional product candidates. We currently have several programsin the research, discovery and preclinical stages of development. Identifying, developing, obtaining regulatory approval for, and commercializing additional product candidates for the treatment of neurodegenerative and lysosomal storage diseases will require substantial additional funding and is prone to the risks of failure inherent in drug development. We cannot provide you any assurance that we will be able to successfully identify or acquire additional product candidates, advance any of these additional product candidates through the development process, successfully commercialize any such additional product candidates, if approved, or assemble sufficient resources to identify, acquire, develop or, if approved, commercialize additional product candidates. If we are unable to successfully identify, acquire, develop, and commercialize additional product candidates, our commercial opportunity may be limited.

We have concentrated a substantial portion of our research and development efforts on the treatment of neurodegenerative and lysosomal storage diseases, fields that have seen limited success in drug development. Further, our product candidates are based on new approaches and novel technology, which makes it difficult to predict the time and cost of product candidate development and subsequently obtaining regulatory approval.

Previous wording
We have focused our research and development efforts on addressing neurodegenerative and lysosomal storage diseases. Collectively, efforts by biopharmaceutical companies in the fields of neurodegenerative and lysosomal storage diseases have seen limited success in drug development. There are few effective therapeutic options available for patients with neurodegenerative diseases, such as Alzheimer’s disease, Parkinson’s disease, and ALS, and lysosomal storage diseases, such as Hunter syndrome and Sanfilippo syndrome. Our future success is highly dependent on the successful development of our BBB platform technology and our product candidates for treating neurodegenerative and lysosomal storage diseases. Developing and, if approved, commercializing our product candidates for treatment of neurodegenerative and lysosomal storage diseases subjects us to a number of challenges, including engineering product candidates to cross the BBB to enable optimal concentration of the therapeutic in the brain and obtaining regulatory approval from the FDA and other regulatory authorities who have only a limited set of precedents to rely on.

We could also encounter delays if a clinical trial is suspended or terminated by us or our collaborators, by the data safety monitoring board for such trial, or by any regulatory authority, or if the IRBs of the institutions in which such trials are being conducted suspend or terminate the participation of their clinical investigators and sites subject to their review. Such authorities may suspend or terminate a clinical trial due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA, EMA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a product candidate, changes in governmental regulations or administrative actions, or lack of adequate funding to continue the clinical trial.

For example, in January 2022, we announced that the TAK-920/DNL919 (ATV:TREM2) IND application had been placed on clinical hold by the FDA. In August 2023 we announced that, in agreement with Takeda, we would discontinue clinical development of TAK-920/DNL919 in Alzheimer’s disease. We cannot assure you that we will ever resume the clinical program for TAK-920/DNL919, nor can we assure you that our other product candidates will not be subject to new, partial or full clinical holds in the future, which may impact development plans.

Previous wording
Our inability to enroll and retain a sufficient number of patients for our clinical trials would result in significant delays or may require us to abandon one or more clinical trials altogether. Enrollment delays in our clinical trials may result in increased development costs for our product candidates and jeopardize our ability to obtain marketing approval for the sale of our product candidates. Furthermore, even if we are able to enroll a sufficient number of patients for our clinical trials, we may have difficulty maintaining participation in our clinical trials through the treatment and any follow-up periods, which could delay or negatively impact the anticipated readouts from our clinical trials, delay our regulatory submissions, and increase the costs of the clinical trials.

Previous wording
Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the clinical trial process. The results of preclinical studies of our product candidates may not be predictive of the results of early-stage or later-stage clinical trials, and results of early clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials. The results of clinical trials in one set of patients or disease indications may not be predictive of those obtained in another. In some instances, there can be significant variability in safety or efficacy or potency results between different clinical trials of the same product candidate due to numerous factors, including changes in trial procedures set forth in protocols, differences in the size and type of the patient populations, changes in and adherence to the dosing regimen and other clinical trial protocols and the rate of dropout among clinical trial participants. Open-label extension studies may also extend the timing and increase the cost of clinical development substantially. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy or potency profile despite having progressed through preclinical studies and initial clinical trials. A number of companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or potency or unacceptable safety issues, notwithstanding promising results in earlier trials. This is particularly true in neurodegenerative diseases and lysosomal storage diseases, where failure rates historically have been higher than in many other disease areas. Most product candidates that begin clinical trials are never approved by regulatory authorities for commercialization.

Previous wording
Even if such clinical trials are successfully completed, we cannot guarantee that the FDA will approve the product candidates for the proposed indications, and more trials could be required before we submit our product candidates for approval. To the extent that the results of the trials are not satisfactory to the FDA or foreign regulatory authorities for support of a marketing application, we may be required to expend significant resources, which may not be available to us, or to conduct additional trials in support of potential approval of our product candidates. Even if regulatory approval is secured for any of our product candidates, the terms of such approval, such as requiring us to narrow our indications to a smaller subset, may also limit its commercial potential.

Our most advanced product candidates, BIIB122/DNL151, DNL310, eclitasertib (SAR443122/DNL758), DNL343, TAK-594/DNL593, and DNL126 are currently our only clinical stage product candidates. Adverse events and other side effects may result from higher dosing, repeated dosing, and/or longer-term exposure to our product candidates and could lead to delays and/or termination of the development of these product candidates. For example, in August 2023, together with our collaboration partner Takeda, we made the strategic decision to discontinue clinical development of TAK-920/DNL919 in Alzheimer's disease following a clinical hold by the FDA.

A number of large pharmaceutical and biotechnology companies are developing products for the treatment of the neurodegenerative and lysosomal storage disease indications for which we have research programs, including Alzheimer’s disease, Parkinson’s disease, Hunter syndrome, and ALS. Companies that we are aware are developing therapeutics in the neurodegenerative and lysosomal storage disease areas include companies with significant financial resources. In addition to competition from other companies targeting neurodegenerative indications, any products we may develop may also face competition from other types of therapies, such as gene-editing therapies.

If any of our small molecule product candidates obtain regulatory approval, additional competitors could enter the market with generic versions of such drugs, which may result in a material decline in sales of affected products.
Current report — wording carried from elsewhere
Under the Drug Price Competition and Patent Term Restoration Act of 1984 (the "Hatch-Waxman Act"), a pharmaceutical manufacturer may file an abbreviated new drug application ("ANDA") seeking approval of a generic copy of an approved, small molecule innovator product. Under the Hatch-Waxman Act, a manufacturer may also submit a new drug application ("NDA") under section 505(b)(2) that references the FDA’s prior approval of the small molecule innovator product. A 505(b)(2) NDA product may be for a new or improved version of the original innovator product.

We plan to seek accelerated approval of DNL310. If successful, we expect the FDA will require us to conduct a confirmatory study to verify the predicted clinical benefit and safety profile. The results from the confirmatory study may not support the clinical benefit or safety profile, which would result in approval being withdrawn. The Food and Drug Omnibus Reform Act reformed the accelerated approval pathway, such as requiring the FDA to specify conditions for post-approval study requirements and setting forth procedures for the FDA to withdraw a product on an expedited basis for non-compliance with post-approval requirements. An unsuccessful post-marketing study or failure to complete such a study could result in the withdrawal of marketing approval.

Our directors, executive officers, holders of more than 5% of our outstanding stock, and their respective affiliates beneficially own a significant percentage of our outstanding common stock. As a result, these stockholders, if they act together, may significantly influence all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions. In addition, pursuant to a nominating agreement between us and Baker Brothers Life Sciences L.P. and 667, L.P. ("Baker Brothers"), if Baker Brothers were to beneficially own at least 10% of our common stock, we would have the obligation to support the nomination of, and to cause our board of directors to include in the slate of nominees recommended to our stockholders for election, one individual designated by Baker Brothers, subject to customary conditions and exceptions.

If we obtain FDA approval for any of our product candidates and begin commercializing those products in the United States, our operations will be subject to various federal, state, local, and foreign healthcare fraud and abuse laws. The laws that may impact our operations include the federal Anti-Kickback Statute, the False Claims Act, the federal Health Insurance Portability and Accountability Act of 1996 ("HIPAA"), as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 ("HITECH"), the federal Physician Payment Sunshine Act, federal consumer protection and unfair competition laws, and analogous state and foreign laws and regulations. These laws may impact, among other things, our clinical research program, as well as our proposed and future sales, marketing, and education programs. In particular, the promotion, sales, and marketing of healthcare items and services is subject to extensive laws and regulations designed to prevent fraud, kickbacks, self-dealing, and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive, and other business arrangements.
