An investment in our stock involves risks. You should carefully read this entire report and consider the following uncertainties and risks, which may adversely affect our business, financial condition or results of operations, along with all of the other information included in our other filings with the SEC, before making an investment decision regarding our common stock. Additionally, while some of the factors, events and contingencies described herein may have occurred in the past, the disclosures herein are not representations as to whether or not they have occurred and are instead provided because future occurrences thereof could adversely affect us. Risks Relating to Our Business Financial and Liquidity Risks We may not achieve sustained profitability. Although we achieved net income on a U.S. GAAP basis for the year ended December 31, 2025 for the first time on an annual basis, we have not yet achieved sustained profitability. Our expectations as to the sustainability of our profitability may change based upon our ability to execute our commercialization goals and operational initiatives and whether or not the assumptions underlying our projected revenues and expenses are correct. Our beliefs and projections regarding the attainment of our financial goals may differ from actual results based on market factors like competition, patient and physician acceptance of our products, reimbursement levels, or on our ability to execute our operational and budget plans, including management’s ability to properly forecast our capital allocation needs. To achieve sustained profitability, we, or our collaborative partners, must successfully manufacture and develop or acquire products and product candidates, receive regulatory approvals, and successfully commercialize our products and/or enter into profitable commercialization arrangements with other parties. Even if we are able to successfully commercialize our existing products, or to develop or otherwise acquire new commercially viable products, certain obligations we have to third parties, including, without limitation, our obligation to pay RPI and OMERS, as applicable, royalties on certain revenues from ORLADEYO under the Royalty Purchase Agreements (as defined in “Note 7—Royalty Financing Obligations” in the Notes to the Condensed Consolidated Financial Statements in Part I, Item 1 of this report), may reduce the profitability of such products. Because of the numerous risks and uncertainties associated with developing or acquiring product candidates, launching new products, and their potential for commercialization, we are unable to predict the extent of any potential 49 Table of Contents future losses. Even though we have achieved profitability in a given reporting period, we may not be able to sustain or increase profitability on a quarterly or annual basis. For example, as a result of the accounting treatment for the Merger, we recorded a net loss on a U.S. GAAP basis for the quarter ended March 31, 2026, due to a special, non-cash charge related to the acquired in-process research and development asset for navenibart. If we are unable to achieve sustained profitability on our anticipated timeline, or at all, the market value of our common stock will likely decline. We may need to raise additional capital or obtain additional financing in the future. If we are unable to raise capital or obtain additional financing if and when needed, we may need to adjust our operations. We have sustained operating losses for the majority of our corporate history. Even if we achieve sustained profitability, in order to continue future operations, progress any development programs, engage in strategic business development activities and commercialize our products and product candidates, we may be required to raise additional capital or obtain additional financing in the future. In addition to seeking strategic partnerships and transactions, we may access the equity or debt markets, incur additional borrowings, or seek other sources of funding to meet liquidity needs at any time, including to take advantage of attractive opportunities in the capital markets. Additional funding, whether through additional sales or issuances of securities, additional borrowings, collaborative arrangements with partners, or from other sources, may not be available if or when needed or in a form or on terms acceptable to us. The issuance of preferred or common stock or convertible securities, with terms and prices significantly more favorable than those of our currently outstanding common stock, could have the effect of diluting or adversely affecting the holdings or rights of our existing stockholders. Additional borrowings may subject us to more restrictive covenants than are currently applicable to us under the Blackstone Loan Agreement. In addition, collaborative arrangements may require us to transfer certain material rights to our corporate partners. Insufficient funds or lack of an acceptable partnership have in the past, and may again in the future, require us to delay, scale-back or eliminate certain of our research and development programs. As our programs advance, our costs could increase. Our expenses, revenues and cash utilization rate could vary significantly depending on many factors, including: our ability to effectively manage our product candidate pipeline; our ability to obtain regulatory approvals for our product candidates; our ability to maintain regulatory approvals for, successfully commercialize, and achieve sustained market acceptance of our products; our future business development activities; our ability to secure partnerships with third parties for our product candidates when deemed advisable; the amount of funding we receive from partnerships with third parties for the development and commercialization of our products and product candidates; the commercial success of our products achieved by our partners; the progress and results of our current and proposed clinical trials for our product candidates; and the progress made in the manufacture of our lead products and the progression of our other programs. Our liquidity needs will largely be determined by the success of operations in regard to the commercialization of our products, particularly ORLADEYO, the progression of our product candidates, including the progress, timeline and ultimate outcome of our development programs (including, but not limited to, formulation progress, long-term human safety studies, clinical trial investigations, and carcinogenicity, drug-drug interaction, toxicity, or other required studies), as well as any post-approval studies for our products, and our ability to execute our budget plans. Constriction and volatility in the equity and debt markets, including as a result of the impacts of inflation, increased interest rates, disruption or instability in the banking industry, geopolitical instability, or public health emergencies such as the COVID-19 pandemic, may restrict our future flexibility to raise capital if and when such needs arise. Our current plans for managing our liquidity needs primarily include controlling the timing and spending on our research and development programs and commercializing our approved products. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources” in Part I, Item 2 of this report for additional information about our liquidity needs, capital requirements, potential funding alternatives, and adequacy of available funds. Furthermore, we have exposure to many different industries, financing partners and counterparties, including commercial banks, investment banks and partners (which include investors, licensing partners, distribution partners, and others), which may be unstable or may become unstable in the current economic and political environment, including as a result of the impacts of inflation, increased interest rates, disruption or instability in the banking industry, U.S. Government shutdowns, changes in presidential administration in the United States, geopolitical instability, actual or threatened public health emergencies, outbreaks of disease, epidemics or pandemics (such as the COVID-19 pandemic). Any such instability may impact these parties’ ability to fulfill contractual obligations to us, or it might limit or place burdensome conditions upon future transactions with us. Also, it is possible that suppliers may be negatively impacted as a result of economic and political instability. Any such unfavorable outcomes in our current programs or unfavorable economic conditions have in the past and could again place severe downward pressure on the price of our common stock and may decrease opportunities to raise capital in the capital or credit markets, and further could reduce the return available on invested corporate cash, 50 Table of Contents which, if severe and sustained, could have a material and adverse impact on our results of operations and cash flows and limit our ability to continue development and commercialization of our products and product candidates. There can be no assurance that any of our plans will be successful or that additional capital will be available to us on reasonable terms, or at all, if needed. If we are unable to obtain sufficient additional capital if and when needed, we may be forced to adjust or curtail our operations; delay, reduce, or stop ongoing clinical trials or commercialization efforts; cease operations altogether; or file for bankruptcy. Risks Relating to the Merger The anticipated benefits and synergies of the Merger may not be realized, and risks associated with Astria’s business or product candidates could adversely affect our business, financial results and the market price of our common stock. The success of the Merger depends, in part, on our ability to integrate Astria into our business and realize the anticipated benefits, cost savings and synergies of the transaction. While we have generally completed the integration of Astria with our business, those benefits may not be realized fully or at all, may take longer to realize than expected, or may not offset transaction and integration expenses over time. An inability to realize the full extent of the anticipated benefits of the Merger could have an adverse effect on our revenues and expenses. Although we conducted due diligence on Astria before completing the Merger, we may not yet be aware of all material risks, liabilities or challenges associated with Astria’s business or product candidates (in particular, navenibart). Unexpected risks may arise, and previously known risks may materialize in a manner that differs from our preliminary risk assessments or assumptions. Any failure to realize the expected benefits of the Merger, any adverse effects from risks related to Astria’s business, or any effect of the Merger on our financial results that is inconsistent with the expectations of financial analysts or investors could cause the market price of our common stock to decline. In addition, former Astria securityholders may decide not to hold the shares of our common stock they received in connection with the Merger, and our stockholders may decide to reduce their investment in us as a result of changes to our investment profile following the Merger, which may result in further fluctuations in the market price of our common stock, including a stock price decrease. Any such decline in the market price of our common stock could adversely affect our ability to issue additional securities or obtain financing in the future. Risks Relating to Product Development and Commercialization Our success depends in part upon our ability to manage our product candidate pipeline, advance our product candidates through the various stages of development, especially through the clinical trial process, and to receive regulatory approvals for the commercial sale of our product candidates. The success of our business depends in part upon our ability to manage our product candidate pipeline, including through expanding the pipeline, as appropriate, through in-licensing or acquiring products or product candidates and integrating them into our business effectively and efficiently; advancing our product candidates through the various stages of development; and receiving regulatory approvals for the commercial sale of our product candidates. In June 2026, we announced the Birmingham Closure Plan to discontinue our internal discovery programs as part of a strategic shift to focus on identifying and advancing high-value opportunities through external innovation. As a result of this decision, we will generally not be able to expand our pipeline with internal product candidates. Identifying, selecting, and in-licensing or acquiring products or product candidates requires substantial expense and technical and financial expertise, and if we are unable to effectively manage our pipeline, expand our portfolio of product candidates through acquisitions or in-licensing, or integrate viable products or product candidates into our business on acceptable terms, or at all, our business and product development efforts could suffer. To receive the regulatory approvals necessary for the commercial sale of our product candidates, we or our partners must demonstrate through preclinical studies and clinical trials that each product candidate is safe and effective. The development process and related regulatory process are complex and uncertain. The preclinical and clinical development of our product candidates is susceptible to the risk of failure inherent at any stage of drug or biologic development, including failure to demonstrate efficacy, or for biologics, purity and potency, and safety, failure to demonstrate adequate benefit-risk balance, failure to achieve a commercially attractive and competitive product label, failure to achieve approval in commercially attractive indications, the occurrence of adverse events that are severe or medically or commercially unacceptable, our or our partners’ failure to comply with trial protocols, applicable regulatory requirements, or industry standards, or a determination by the FDA or any comparable foreign regulatory authority that a product candidate may not continue development or be approved in accordance with our development plans or at all. The outcome of preclinical testing and early clinical trials may not be predictive of the success of later clinical trials, and interim results of a clinical 51 Table of Contents trial do not necessarily predict final results. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and for some product candidates, there may not be an ideal model for preclinical testing. We also cannot guarantee that any preclinical studies and clinical trials will be conducted as planned or completed on schedule, if at all, or that the results of such trials will be sufficient to support regulatory approval for our product candidates. Progression of our product candidates through the clinical development process is dependent upon our trials indicating that our product candidates have adequate safety and efficacy or purity and potency in the patients being treated by achieving predetermined endpoints according to the clinical trial protocols, as well as an adequate benefit-risk profile. Failure to achieve any of these endpoints or to show adequate benefit-risk profile in any of our programs has in the past, and could again in the future, result in delays in, modifications to, or discontinuations of our trials or require the performance of additional unplanned trials. If any of our product candidates is associated with adverse events or undesirable side effects or has properties that are unexpected, we may need to abandon development or limit development of that product candidate to certain uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent, less severe or more acceptable from a benefit-risk perspective. Product candidates that initially show promise in clinical or preclinical testing have in the past, and could again in the future, later be found to be associated with or to cause undesirable or unexpected side effects that could result in substantial modifications or delays in the development plans for our product candidates, significant unexpected costs, or the termination of programs. In addition, the development plans for our product candidates, including our clinical trials, may not be adequately designed or executed, which could negatively affect the outcome and analysis of study results. Because of the cost and duration of clinical trials, we have decided in the past, and may in the future decide, to discontinue development of product candidates for various reasons, including, but not limited to, that such product candidates are unlikely to show favorable results in clinical trials, unlikely to help advance a product to the point of a meaningful collaboration, or unlikely to have reasonable commercial potential. Undesirable or inconclusive data in our or our partners’ preclinical studies and clinical trials or side effects in humans could result in the FDA or foreign regulatory authorities refusing to approve a product candidate for any targeted indications or imposing restrictions or warnings that could impact development or the ultimate commercial viability of a product candidate. In addition, the FDA or foreign regulatory authorities may determine that study data from our product candidates necessitates additional studies or study designs which differ from our planned development strategy, and such regulatory authorities may also require patient monitoring and testing or may implement restrictions or other conditions on our development activities, any of which could materially impact the cost and timing of our planned development strategy. We, our partners, the FDA, or foreign regulatory authorities have previously, and may again in the future, pause enrollment in, suspend, or terminate clinical trials at any time if we or they believe the trial participants face unacceptable health risks. Our ability to complete the clinical development process successfully is dependent upon many factors, including, but not limited to: •our or our partners’ ability to secure suitable clinical sites and investigators and to enroll and maintain an adequate number of patients on a timely basis or at all; •patients that enroll in a clinical trial may not comply with the clinical trial protocols or maintain contact with investigators to provide complete data during and after treatment; •our product candidates may not prove to be either safe or effective for our targeted indications, or at all, or may produce unfavorable or inconclusive results; •we or our partners may decide, or be required by regulatory authorities, to pause enrollment in, suspend, or terminate clinical research for various reasons, including a finding that the participants are being exposed to unacceptable health risks, undesirable side effects or other unexpected characteristics of the product candidate, noncompliance with regulatory requirements or their standards of conduct or evolving guidance, or findings of undesirable effects caused by a chemically or mechanistically similar product or product candidate; •regulatory authorities may disagree with our or our partners’ clinical trial protocols or our or their interpretation of data from preclinical studies and clinical trials; •clinical protocols or study procedures may not be adequately designed or followed by the investigators, including ensuring that all data is accurately recorded and reported; •formulation improvements may not work as expected, which could negatively impact commercial demand for our product candidates; •regulatory authorities may fail to approve or subsequently find fault with the manufacturing processes or facilities of third-party manufacturers with which we or our partners enter into agreements for clinical and commercial supplies; 52 Table of Contents •the supply or quantity of raw materials or manufactured product candidates or other materials necessary to conduct development activities may be insufficient, inadequate, or unavailable at an acceptable cost, and we or our partners may experience interruptions in supply; •our or our partners’ development plans may be delayed or changed as a result of changes in development strategy, the impact of new or different regulations, requirements, and guidelines, or other unexpected events or conditions; •the cost of preclinical studies and clinical trials may be greater than we anticipate; •we or our third-party contractors, including those manufacturing our product candidates or components or ingredients thereof, or conducting clinical trials or laboratory testing on our or our partners’ behalf, may fail to comply with regulatory requirements and industry standards or meet contractual obligations in a timely manner or at all; and •the impact of any global health epidemic or pandemic, such as COVID-19, on one or more of the foregoing factors. Clinical trials are lengthy and expensive. Many of the factors listed above could result in increased clinical development costs or longer clinical development times for any of our programs. We and our partners incur substantial expense for, and devote significant time to, preclinical testing and clinical trials, yet we cannot be certain that the tests and trials will ever result in the commercial sale of a product. Even if we or our partners successfully complete clinical trials for our product candidates, we or our partners might not file the required regulatory submissions in a timely manner or may not receive regulatory approval for the product candidates, which in either case would adversely impact or preclude our ability to generate any revenues from product sales or licensing arrangements. In addition, any product candidate, if approved, may be subject to restrictions on labeling, marketing, distribution, prescribing, and use, which could adversely impact the sales of such product. If our development collaborations with third parties, such as our development partners, contractors and contract research organizations, fail, the development of our product candidates will be delayed or stopped. We rely heavily upon third parties for many important stages of our product candidate development, including, but not limited to: •discovery of natural proteins that cause or enable biological reactions necessary for the progression of the disease or disorder; •execution of certain pharmacology preclinical studies and late-stage development for our compounds and product candidates; •management of our phase 1, 2 and 3 clinical trials, including medical monitoring, laboratory testing, and data management; •execution of toxicology studies that may be required to obtain approval for our product candidates; •formulation improvement strategies and methods; •manufacturing the starting materials and drug substance required to formulate our products and the product candidates to be used in our clinical trials, toxicology studies and any potential commercial product; •provision of cell banks or cell line technologies; and •management of certain regulatory interactions outside of the United States. Our failure to engage in successful collaborations at any one of these stages would greatly impact our business. If we do not license protein targets or inhibitors from academic institutions or from other biotechnology companies on acceptable terms, or at all, our product development efforts could suffer. Similarly, if the contract research organizations or third-party contractors that conduct our initial or late-stage clinical trials, conduct our toxicology or other studies, manufacture our starting materials, drug substance and product candidates, provide laboratory testing or other services (including clinical operation services) in connection with our clinical trials, provide medical writing services, or assist with our regulatory function breach their obligations to us, perform their services inconsistent with industry standards, or fail to comply with regulatory requirements, this would delay or prevent both the development of our product candidates and the availability of any potential commercial product. If we lose our relationship with any one or more of these parties, we could experience a significant delay in both identifying another comparable provider and then contracting for its services. We may be unable to retain an alternative provider on reasonable terms, if at all. Even if we locate an alternative provider, it is likely that this provider may need additional time to respond to our needs and may not provide the same type or level of service as the original provider. In addition, any provider that we retain will be subject to applicable FDA current Good Laboratory Practices, current Good Manufacturing Practices (“cGMP”), and current Good Clinical Practices, and comparable foreign standards. We do not 53 Table of Contents have control over compliance with these regulations by these providers. Consequently, if these practices and standards are not adhered to by these providers, the development and commercialization of our product candidates could be delayed. If any of the foregoing risks is realized, our business, financial condition and results of operations could be materially adversely affected. If we or our partners do not obtain regulatory approvals for our product candidates or maintain regulatory approvals for our products, we or our partners will not be able to commercialize and sell these products and potential products, which would significantly harm our business because we will receive no revenue. We or our partners must obtain regulatory approvals before marketing or selling our products. If the FDA or a comparable foreign regulatory authority delays or denies regulatory approval of one of our product candidates, or revokes approval of a previously approved product, we would be unable to market or sell the product in the applicable jurisdiction and would not receive revenue from sales or licensing arrangements related thereto, which could have a material and adverse impact on our business. The process of preparing for and obtaining regulatory approval in any jurisdiction may be lengthy and expensive, and approval is never certain. Because of the risks and uncertainties inherent to the development process, our product candidates could take a significantly longer time to gain regulatory approval than we expect or may never gain approval. As discussed under “Risk Factors—Risks Relating to Our Business—Risks Relating to Product Development and Commercialization—Our success depends in part upon our ability to manage our product candidate pipeline, advance our product candidates through the various stages of development, especially through the clinical trial process, and to receive regulatory approvals for the commercial sale of our product candidates,” we and our partners have experienced, and may again in the future experience, any number of unfavorable outcomes during or as a result of preclinical studies and clinical trials that could delay or prevent regulatory approval of our product candidates, or negatively impact our management’s credibility, our value and our operating results. Even if the FDA or foreign regulatory authorities approve a product candidate, the approval may limit the indicated uses for a product candidate, impose other restrictions on the product candidate, and/or may require post-approval studies that could impair the commercial viability of a product candidate. Even upon any approval to market our potential products, whether in the United States or internationally, we will continue to be subject to extensive regulatory requirements, as discussed under “Risk Factors—Risks Relating to Our Business—Legal and Regulatory Risks—We are subject to various laws and regulations related to our products and product candidates, and if we or our partners do not comply with these laws and regulations, we could face substantial penalties.” Our failure to comply with existing or future regulatory requirements for regulatory approval, or our loss of, or changes to, previously obtained approvals, could impair our ability to generate any revenues from product sales or licensing arrangements, which could have a material adverse effect on our business, financial condition, and results of operations. We focus primarily on rare diseases, which may create additional risks and challenges, including that the target patient populations of our products and product candidates may be small. Because we focus primarily on developing drugs as treatments for rare diseases, we may seek orphan drug, breakthrough therapy or fast track designations for our product candidates in the United States or the equivalent designations elsewhere in the world. Often, regulatory authorities have broad discretion in determining whether or not to grant such designations. We cannot guarantee that our product candidates will receive orphan drug status from the FDA or equivalent designations from other regulatory authorities. Even with an orphan drug designation for our current and potential future product candidates, we may not be the first to obtain marketing approval for any particular orphan indication due to the uncertainties associated with developing pharmaceutical products. Further, even if we obtain orphan drug exclusivity for an existing or future product candidate, that exclusivity may not effectively protect the product from competition. In addition, we do not know if, when, or how the FDA, Congress, or future judicial challenges may change the orphan drug regulations and policies in the future, and it is uncertain how any changes might affect our business. Depending on what changes the FDA may make to its orphan drug regulations and policies, our business could be adversely impacted. See “Business—Government Regulation—FDA Regulation—Orphan Drugs” in Part I, Item 1 of our most recent Annual Report on Form 10-K. We also cannot guarantee that we will receive breakthrough therapy, fast track, or equivalent designations, which provide certain potential benefits such as more frequent meetings with the applicable regulatory authorities to discuss 54 Table of Contents development plans, intensive guidance on efficient product development programs, and potential eligibility for rolling review or priority review. Even if we are successful in obtaining any such designations for our product candidates, such designations may not lead to faster development or regulatory review or approval and do not increase the likelihood that our product candidates will receive marketing approval. We may not be able to obtain or maintain these designations for our product candidates that receive them, and our competitors may obtain these designations for their product candidates, which could impact our ability to develop and commercialize our products and product candidates or compete with such competitors, which may adversely impact our business, financial condition or results of operations. Given the small number of patients who have the diseases that we are targeting, it is important to our ability to grow and sustain profitability that we continue to successfully identify patients with these rare diseases. Our projections of both the number of people who have these diseases, as well as the subset of people with these diseases who have the potential to benefit from treatment with our products and product candidates, are based on our beliefs and estimates. These estimates have been derived from a variety of sources, including the scientific literature, surveys of clinics, patient foundations, or claims-based market research studies, and may prove to be incorrect. Further, new studies may change the estimated incidence or prevalence of these diseases. The number of patients may turn out to be lower than expected. Additionally, the potentially addressable patient population for each of our products and product candidates may be limited or may not be amenable to treatment with our products and product candidates, and new patients may become increasingly difficult to identify or access. Further, even if we obtain significant market share for our products and product candidates, because the potential target populations are small, we may not maintain profitability or generate sufficient long-term revenue growth to sustain our business. If the FDA or comparable foreign regulatory authorities approve generic versions of any of our drug products that receive marketing approval, or such authorities do not grant our products appropriate periods of data or market exclusivity before approving generic versions of our products, the sales of our products could be adversely affected. Once a new drug application (“NDA”) is approved, the drug covered thereby becomes a “reference-listed drug” in the FDA’s publication, “Approved Drug Products with Therapeutic Equivalence Evaluations.” Manufacturers may seek marketing approval of generic versions of reference-listed drugs through submission of abbreviated new drug applications, or ANDAs, in the United States, as described in “Business—Government Regulation—FDA Regulation—Abbreviated New Drug Applications for Generic Drugs” in Part I, Item 1 of our most recent Annual Report on Form 10-K. Generic drugs may be significantly less costly to bring to market than the reference-listed drug and companies that produce generic drugs are generally able to offer them at lower prices. Thus, following the introduction of a generic drug, a significant percentage of the sales of any branded product or reference-listed drug is typically lost to the generic drug. The FDA may not approve an ANDA for a generic drug until any applicable period of non-patent exclusivity for the reference-listed drug has expired, as described in “Business—Government Regulation—FDA Regulation—Abbreviated New Drug Applications for Generic Drugs” in Part I, Item 1 of our most recent Annual Report on Form 10-K, but such exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would be required to conduct or obtain a right of reference to all of the nonclinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness. Manufacturers may seek to launch generic drugs following the expiration of the marketing exclusivity period, even if we still have patent protection for such drugs. Competition that our drug products or product candidates may face from generic drugs could materially and adversely impact our future revenue, profitability and cash flows and substantially limit our ability to obtain a return on the investments we have made in those product candidates. Our future revenues, profitability and cash flows could also be materially and adversely affected and our ability to obtain a return on the investments we have made in those product candidates may be substantially limited if our products or, if and when approved, product candidates, are not afforded the appropriate periods of non-patent exclusivity. We may face competition from biosimilars, which may have a material adverse impact on the future commercial prospects of our biological products and product candidates. Even if we are successful in achieving regulatory approval to commercialize a biological product candidate faster than our competitors, we may face competition from biosimilars with respect to our biological product candidates. In the United States, the Biologics Price Competition and Innovation Act (“BPCIA”) was included in the Affordable Care Act (“ACA”) and created an abbreviated approval pathway for biological products that are demonstrated to be “highly similar,” or biosimilar, to or “interchangeable” with an FDA-approved biological product. The BPCIA prohibits the FDA from approving a biosimilar or interchangeable product that references a brand biological product until 12 years after the licensure of the reference product, but permits submission of an application for a biosimilar or interchangeable product to 55 Table of Contents the FDA four years after the reference product was first licensed. The BPCIA does not prevent another company from developing a product that is highly similar to the innovative product, generating its own data, and seeking approval. The law is complex and continues to evolve through ongoing FDA implementation and judicial interpretation. As a result, its ultimate impact, implementation and meaning are subject to uncertainty. Modification of the BPCIA, or changes to the interpretation or implementation of the BPCIA, could have a material adverse effect on the future commercial prospects for our biological products and product candidates. If competitors are able to obtain marketing approval for biosimilars referencing our biological products, our biological products may become subject to competition from such biosimilars, with the attendant competitive pressure and consequences which could adversely affect our business and financial results. The commercial viability of any approved product could be compromised if the product is less effective than expected, causes undesirable side effects that either were not previously identified or were worse than expected, or fails to achieve market acceptance within the medical community. If, after obtaining regulatory approval of a product, we or others discover that the product is less effective than previously believed or causes undesirable side effects that either were not previously identified or were worse than expected, any of the following adverse events could occur: •regulatory authorities may withdraw their approval of, or impose marketing or manufacturing restrictions on, the product, or require us or our partners to create a medication guide outlining the risks of unidentified side effects for distribution to patients; •we or our partners may be required to recall the product, change the way the product is administered, conduct additional clinical trials, or be subject to civil or criminal penalties; and •the product may become less competitive and our reputation may suffer. Even after receiving regulatory approval, any product could fail to gain sufficient, or any, market acceptance by physicians, patients, third-party payors, health authorities and others in the medical community. For example, physicians are often reluctant to switch their patients from existing therapies even when new and potentially more effective or convenient treatments enter the market. Further, patients often acclimate to the therapy that they are currently taking and do not want to switch unless their physicians recommend switching products or they are required to switch therapies due to lack of reimbursement for existing therapies. If an approved product does not achieve an adequate level of market acceptance, it may not generate significant revenues. The occurrence of any of the foregoing could have a material and adverse impact on our business. If we fail to successfully commercialize or establish collaborative relationships to commercialize or develop certain of our products and product candidates, or if any partner terminates or fails to perform its obligations under agreements with us, potential revenues from commercialization of our products and product candidates could be reduced, delayed or eliminated. Our business strategy includes successfully commercializing our product and product candidate portfolio. We believe this is best achieved by retaining full product rights or through collaborative arrangements with third parties as appropriate. As needed, potential third-party relationships could relate to preclinical development, clinical development, regulatory approval, marketing, sales, and distribution of our products and product candidates. Currently, we have established collaborative relationships including with, among others, third-party distributors for ORLADEYO in certain markets, with Torii for ORLADEYO in Japan, with Neopharmed for the commercialization of ORLADEYO and navenibart in Europe, and with each of Shionogi and Green Cross for the development and commercialization of peramivir. In addition, in August 2025, Astria announced that it exclusively licensed development and commercialization rights in Japan to Kaken for navenibart. The process of establishing and implementing collaborative relationships is difficult, time-consuming and involves significant uncertainty, including: •we or our partners may seek to renegotiate or terminate our relationships due to unsatisfactory commercial, regulatory or clinical results, including post-approval clinical commitments, a change in business strategy, a change of control or other reasons; •our contracts for collaborative arrangements may expire; •the possibility that expiration or termination of collaborative relationships, such as those with certain of our distribution partners, may trigger repurchase obligations of the Company for unsold product held by our partners; •our partners may choose to pursue alternative technologies, including those of our competitors; 56 Table of Contents •we have had in the past, and in the future may have, disputes with a partner that could lead to litigation or arbitration, which could result in substantial costs and divert the attention of our management; •we do not have day-to-day control over the activities of our partners and have limited control over their decisions; •our ability to generate future event payments and royalties from our partners depends upon their abilities to establish the safety and efficacy of our product candidates, obtain regulatory approvals and achieve market acceptance of products developed from our product candidates; •we or our partners may fail to properly initiate, maintain or defend our intellectual property rights, where applicable, or a party may utilize our proprietary information in such a way as to invite litigation that could jeopardize or potentially invalidate our proprietary information or expose us to potential liability; •we or our partners may not devote sufficient capital or resources toward our products and product candidates; •our partners may declare bankruptcy or face other financial distress that could put our partnership or collaborative arrangements at risk; and •we or our partners may not comply with applicable government regulatory requirements. If we or our partners fail to fulfill our responsibilities in a timely manner, or at all, our development and commercialization efforts related to that collaboration could be reduced, delayed or terminated, or it may be necessary for us to assume responsibility for activities that would otherwise have been the responsibility of our partner. If we are unable to establish and maintain collaborative relationships on acceptable terms, when or where needed, we may have to delay or discontinue further development or commercialization of one or more of our products or product candidates, undertake commercialization activities at our own expense or find alternative sources of funding. Any delay in the development or commercialization of our products and product candidates would severely affect our business, because if our product candidates do not progress through the development process or reach the market in a timely manner, or at all, or if our products do not achieve market success, we may not receive any revenues from product sales or licensing arrangements. The results of our partnership with Torii may not meet our current expectations. We have a partnership agreement with Torii for ORLADEYO in Japan. Under our agreement with Torii, we are responsible for all field promotional activities with respect to ORLADEYO in Japan, which we conduct through our Japanese subsidiary, BioCryst Japan K.K. Furthermore, we remain responsible for regulatory activities with respect to ORLADEYO in Japan, and we use third parties to satisfy those regulatory responsibilities and certain other obligations in Japan. If any party fails to meet its obligations, the commercial success of ORLADEYO in Japan and the economic benefit expected could be negatively impacted. There can be no assurance that our or our partners’ commercialization efforts, methods, and strategies for our products or technologies will succeed, and our future revenue generation is uncertain. There can be no assurance that our or our partners’ commercialization efforts, methods and strategies will succeed or maintain success. We may be unable to establish or sufficiently increase our sales, marketing and distribution capabilities for products we currently, or plan to, commercialize. Our ability to receive revenue from products we or our partners commercialize is subject to several risks, including: •we or our partners may fail to complete clinical trials successfully, or satisfy post-marketing commitments, sufficient to obtain and maintain regulatory agency marketing approval; •many competitors are more experienced and have significantly more resources, and their products could reach the market faster, be more cost effective or have a better efficacy or tolerability profile than our products and product candidates; •we may fail to employ a comprehensive and effective intellectual property strategy, which could result in decreased commercial value of our Company, our products and product candidates, or royalties associated with such products; •we may fail to employ a comprehensive and effective regulatory strategy, which could result in a delay or failure in commercialization of our products; •our and our partners’ ability to successfully commercialize our products is affected by the competitive landscape; •revenue from product sales depends on our ability to obtain and maintain favorable pricing; •reimbursement is constantly changing, which could greatly affect usage of our products; 57 Table of Contents •future revenue from product sales will depend on our ability to successfully complete clinical studies, obtain regulatory approvals, and manufacture, market, distribute and commercialize our future approved products; •delays in regulatory approvals, product launches, initial shipments, or ongoing supply arising from manufacturing, formulation, or supply chain issues could impede our ability to meet commercial expectations; and •the impact of public health emergencies or the outbreak of disease, such as the COVID-19 pandemic, on us or our partners. In addition, future revenue from sales of ORLADEYO is subject to uncertainties and will depend on several factors, including, but not limited to, the success of our and our partners’ commercialization efforts in the United States and elsewhere, the number of new patients switching to ORLADEYO, patient retention and demand, the number of physicians prescribing ORLADEYO, the rate of monthly prescriptions, reimbursement from third-party and government payors, the number of patients receiving free product, our pricing strategy, and market trends. Additionally, manufacturing issues relating to our products could result in delays, interruptions or recalls in commercial supply, which could adversely affect our revenue and results of operations. For example, in May 2026, we announced that we identified a manufacturing issue affecting our oral pellet formulation of ORLADEYO that delayed our initial product fulfillment. The issue was resolved, and the week of August 3, 2026, we began shipping the ORLADEYO oral pellets in the United States to pediatric patients with HAE aged 2 to <12 years. Even if we are able to successfully commercialize our existing products, or to develop new commercially viable products, certain obligations we have to third parties, including, without limitation, our obligations to pay royalties on certain revenues from ORLADEYO under the Royalty Purchase Agreements, may reduce the profitability of such products. We have experienced significant changes in the scope of our operations and capabilities. In addition, we may continue to change certain aspects of our business in connection with acquisitions, licenses, collaborations or other strategic business development activities. As a result, we may encounter difficulties in managing such changes, which could disrupt our operations. We have experienced significant changes in the scope of our operations, and any future changes resulting from strategic business development opportunities may require us to further evolve our operational, managerial and financial capabilities. To manage such changes, we must continue to implement and improve our managerial, operational and financial systems and processes and recruit, train, and retain qualified personnel as needed. Due to our limited financial resources and the challenges associated with integrating and supporting new programs, technologies, personnel or business activities, we may not be able to effectively manage any future changes to our operations, implement appropriate systems and processes in a timely manner or at all, or recruit, train, and retain qualified personnel. The evolution of our operations, including as a result of acquisitions, licenses, collaborations or other strategic transactions, may lead to significant costs and may divert management and business development resources. In addition, if a commercial launch for any product or product candidate for which we establish commercial or marketing capabilities in any region is delayed or does not occur for any reason, we would have prematurely or unnecessarily incurred these commercialization expenses. Any inability to manage such changes could delay the execution of our business plans or disrupt our operations. We depend on third-party vendors in the manufacture and distribution of our products, product candidates and the materials for our products and product candidates. If we cannot rely on existing third-party vendors, we will be required to incur significant costs and potential delays in finding new third-party vendors, which could adversely impact the development and commercialization timeframes for our products and product candidates. We depend on third-party vendors, including third-party manufacturers, distributors, and specialty pharmacies, in the manufacture and distribution of our products, product candidates, and the materials for our products and product candidates. Often, especially in the early development and commercialization process, we have only one or limited sources for a particular product or service, such as manufacturing and/or distribution. We depend on these third-party vendors to perform their obligations in a timely manner and in accordance with applicable governmental regulations. Our third-party vendors, particularly our third-party manufacturers, distributors, and specialty pharmacies, each of which may be the only vendor we have engaged for a particular product, product candidate, or service or in a particular region, may encounter difficulties with meeting our requirements, including, but not limited to, problems involving, as applicable: •insufficient resources being devoted in the manner necessary to satisfy our requirements within expected timeframes; •inconsistent production yields; 58 Table of Contents •product liability claims or recalls of commercial product; •difficulties in scaling production to commercial and validation sizes; •interruption of the delivery of materials required for the manufacturing process; •failure to distribute commercial supplies of our products to commercial vendors or end users in a timely manner; •scheduling of plant time with other vendors or unexpected equipment failure; •potential catastrophes that could strike their facilities or have an effect on infrastructure; •potential impurities in our drug substance or products that could affect availability of product for our clinical trials or future commercialization; •poor quality control and assurance or inadequate process controls; •failure to provide us with accurate or timely information regarding inventory, the number of patients who are using our products, or serious adverse events and/or product complaints regarding our products; •inability of third parties to satisfy their financial obligations to us or to others; •potential breach of the manufacturing or distribution agreement by the third party; •possible termination or non-renewal of an agreement by the third party at a time that is costly or inconvenient to us; and •lack of compliance or cooperation with regulations and specifications or requests set forth by the FDA or other foreign regulatory agencies or local customs. The process of manufacturing pharmaceutical products, devices and, in particular, biologics, is complex, highly regulated, and subject to multiple risks. Manufacturing biologics is highly susceptible to product loss due to contamination, equipment failure, improper installation or operation of equipment, vendor or operator error, inconsistency in yields, variability in product characteristics, difficulties in scaling the production process and use of excipients which may, among other things, impact shelf life and present concerns with process or quality controls. Even minor deviations from normal manufacturing processes could result in reduced production yields, product defects, other supply disruptions and higher costs. If microbial, viral or other contaminations are discovered at the facilities of our third-party contract manufacturers, such facilities may need to be closed for an extended period of time to investigate and remedy the contamination, which could delay clinical trials, result in higher costs of drug product and adversely affect our business. Many additional factors could cause production or distribution interruptions with the manufacture and distribution of any of our products and product candidates, including human error, natural disasters, pandemics, labor disputes or shortages, acts of terrorism or war, equipment malfunctions, raw material shortages or supply chain issues. If our commercial distribution partners are not able to satisfy our requirements within the expected timeframe, or are unable to provide us with accurate or timely information and data, including with respect to inventory and sales, serious adverse events, and/or product complaints, our business, including our commercialization efforts for and sales of ORLADEYO, may be at risk. In addition, if specialty pharmacy services, including our third-party call center services, which provide patient support and financial services, prescription intake and distribution, reimbursement adjudication, and ongoing compliance support, are not effectively operated or managed, the continuance of our commercialization efforts for and sales of ORLADEYO may be delayed or compromised. On August 5, 2026, we announced that we have transitioned to a new sole source specialty pharmacy provider for ORLADEYO shipments to patients. Any disruption, delay or failure associated with this transition, including interruptions in prescription processing, patient onboarding, reimbursement support or product distribution, could adversely affect our commercialization efforts and our product revenue. In addition, our contract manufacturers may not be able to manufacture the materials required for our products or product candidates at a cost or in quantities necessary to make them commercially viable. Our raw materials, drug substances, products, and product candidates are manufactured by a limited group of suppliers, including some at a single facility. If any of these suppliers were unable to produce these items, this could significantly impact our supply of products and product candidate material for further preclinical testing and clinical trials. Additionally, if we are unable to timely establish an alternate supply from one or more third-party contract manufacturers, we could experience delays in our development efforts as we seek to locate and qualify new or additional manufacturers. For particular products, product candidates, services or particular regions where we rely on a single vendor, these and other related risks are exacerbated for us. Our third-party manufacturers also may not meet our manufacturing requirements, which could result in a delay in approval, or rejection, of our marketing applications by the FDA or other regulatory authority. Furthermore, changes in the manufacturing process or procedures, including a change in the location where the drug is manufactured or a change of a third-party manufacturer, may require prior review and approval in accordance with the FDA’s cGMP and comparable foreign requirements. This review may be costly and time-consuming and could delay or prevent the launch of a product. The FDA or foreign regulatory authorities may at any time implement new standards, or change their interpretation and 59 Table of Contents enforcement of existing standards, for manufacture, packaging or testing of products. If we or our contract manufacturers are unable to comply, we or they may be subject to regulatory action, civil actions or penalties, any of which could be costly to us and could result in a delay or shortage of product. We currently contract with a foreign contract manufacturing organization (“CMO”) in China for the manufacturing of certain of our product candidates. Foreign CMOs may be subject to U.S. legislation, including the BIOSECURE Act, sanctions, trade restrictions and other foreign regulatory requirements, which could increase the cost or reduce the supply of material available to us or delay the procurement or supply of such material. We have in the past and may from time to time in the future reassess our existing third‑party vendor arrangements and determine that changes to one or more vendors are necessary, which could result in delays to development or commercialization. In addition, if we are unable to maintain current third-party relationships, or enter into new agreements with additional third parties on commercially reasonable terms, or at all, or if there is poor manufacturing or distribution performance or failure to comply with any regulatory agency on the part of any of our third-party vendors, we may not be able to complete development of, obtain timely approval of, or commercialize our products and product candidates. If we cannot rely on existing third-party vendors, including our third-party manufacturers, distributors, CROs, or specialty pharmacies, we will be required to incur significant costs and potential delays in finding new third-party vendors, which could adversely impact the development and commercialization timeframes for our products and product candidates and could negatively affect our business, financial results, and revenue. Commercialization of our products by us and our partners is subject to the potential commercialization risks described herein and numerous additional risks. Any potential revenue benefits to us, including in the form of milestone payments, royalties or other consideration, are highly speculative. Commercial success of our products is uncertain and is subject to all the risks and uncertainties disclosed in our other risk factors relating to product development and commercialization. In addition, commercialization of our products is subject to further risks and may be negatively impacted by a number of factors, including, but not limited to, the following: •our products may not prove to be adequately safe and effective for market approval in markets other than the markets in which they are currently approved; •necessary funding for post-marketing commitments and further development of our products may not be available timely, at all, or in sufficient amounts; •advances in competing products could substantially replace potential demand for our products; •government and third-party payors may not provide sufficient coverage or reimbursement, which would negatively impact the demand for our products; •we may not be able to supply commercial material, including supplying sufficient product to meet commercial demand, and we may not be able to maintain or establish sufficient and acceptable commercial manufacturing, either directly or through third-party manufacturers; •the commercial demand for and acceptance of our products by healthcare providers and by patients may not be sufficient to result in substantial product revenues to us or to our partners and may result in little to no revenue, milestone payments, or royalties to us; •effectiveness of marketing and commercialization efforts for our products by us or our partners; •market satisfaction with existing alternative therapies; •perceived efficacy relative to other available therapies; •disease prevalence; •cost of treatment; •our pricing and reimbursement strategy may not be effective; •new legislative or regulatory proposals may influence our pricing and reimbursement strategy, which could impact product revenues; •pricing and availability of imports or alternative products; •marketing and sales activities of competitors; •shifts in the medical community to new treatment paradigms or standards of care; and •relative convenience and ease of administration. Risks Relating to Competing in Our Industry We face intense competition, and if we are unable to compete effectively, the demand for our products may be reduced. The biotechnology and pharmaceutical industries are highly competitive and subject to rapid and substantial technological change. There are many companies seeking to develop products for the same indications that we currently 60 Table of Contents target. Our competitors in the United States and elsewhere are numerous and include, among others, major multinational pharmaceutical and chemical companies and specialized biotechnology firms. Many of these competitors have greater resources than we do, including greater financial resources, larger research and development staffs and more experienced manufacturing, marketing, and sales organizations. In addition, many of our competitors have greater experience than we do in conducting clinical trials and obtaining FDA and other regulatory approvals. Accordingly, our competitors may succeed in obtaining FDA or other regulatory approvals of product candidates more rapidly than we do for products that compete with our products. Companies that complete clinical trials, obtain required regulatory approvals, and commence commercial sale of their drugs before we do may achieve a significant competitive advantage, including patent and FDA exclusivity rights that would delay our ability to market products. We face, and will continue to face, competition in the commercialization of our products, licensing of potential product candidates for desirable disease targets, and development and marketing of our product candidates from academic institutions, government agencies, research institutions and biotechnology and pharmaceutical companies. Competition may also arise from, among other things: •other product development technologies; •methods of preventing or reducing the incidence of disease, including vaccines; and •new small molecule or other classes of therapeutic agents. Developments by others may render our products, product candidates, or technologies obsolete or noncompetitive. We received FDA approval of ORLADEYO, an oral, once-daily therapy for the prevention of HAE attacks in adults and pediatric patients aged 12 years and older, in December 2020, and subsequently received regulatory approvals for ORLADEYO in other global markets. In December 2025, the FDA approved the use of an oral pellet formulation of once-daily ORLADEYO for prophylactic therapy in pediatric patients with HAE aged 2 to <12 years. We are also performing research on or developing products for the treatment of other rare diseases, and we expect to encounter significant competition for our pharmaceutical products and product candidates. Companies that complete clinical trials, obtain required funding or government support, obtain required regulatory approvals and commence commercial sales or stockpiling orders of their products before their competitors may achieve a significant competitive advantage. Various government entities throughout the world may also offer incentives, grants and contracts to encourage additional investment into certain preventative and therapeutic agents, which may have the effect of further increasing the number of our competitors and/or providing advantages to certain competitors. In addition, the approval of a generic drug or biosimilar of one of our products or a product with which we compete could have a material impact on our business because it may be significantly less costly to bring to market and may be priced significantly lower than our products or the other products with which we compete. See “Business—Competition” in Part I, Item 1 of our most recent Annual Report on Form 10-K for further discussion of our competitors, competitive products or programs, and the competitive conditions in these and other therapeutic areas. If one or more of our competitors’ products or programs, including potential competitors not currently identified, are successful, the market for our products may be reduced or eliminated. Compared to us, many of our competitors and potential competitors have substantially greater: •capital resources; •research and development resources, including personnel and technology; •regulatory experience; •preclinical study and clinical testing experience; •manufacturing, marketing, and sales experience; and •production facilities. Any of these competitive factors could impede our funding efforts, render our products, product candidates, or technologies noncompetitive or eliminate or reduce demand for our products and product candidates. Legal and Regulatory Risks We are subject to various laws and regulations related to our products and product candidates, and if we or our partners do not comply with these laws and regulations, we could face substantial penalties. Our and our partners’ activities related to approved products or, following their regulatory approval (if applicable), any of our product candidates under development, are subject to regulatory and law enforcement authorities in the United States (including the FDA, the Federal Trade Commission, the Department of Justice (“DOJ”), the HHS, Office of Inspector General, and state and local governments) and their foreign equivalents. 61 Table of Contents We are responsible for reporting adverse drug or biological product experiences, have responsibility for certain post-approval studies, and may have responsibilities and costs related to a recall or withdrawal of our products from sale in the jurisdictions in which they are approved. We may also incur liability associated with product manufacturing contracted by us or in support of any of our partners. We are required to maintain records and provide data and reports to regulatory agencies related to our products (e.g., risk evaluation and mitigation strategies, track and trace requirements, and adverse events), and we may incur certain promotional regulatory and government pricing risks, all of which could have a material adverse impact on our operations and financial condition. Similar responsibilities would apply upon regulatory approval of any of our other product candidates currently under development. In addition, we are subject to the federal Physician Payment Sunshine Act and certain similar physician payment and drug pricing transparency legislation in various states. We are also subject to various federal and state laws pertaining to healthcare “fraud and abuse,” including both federal and state anti-kickback and false claims laws. Outside of the United States, we may be subject to analogous foreign laws and regulations in the various jurisdictions in which we operate. These laws and regulations apply to our and our partners’ operations, sales and marketing practices, price reporting, and relationships with physicians and other customers and third-party payors. Although we seek to comply with these statutes, it is possible that our practices, or those of our partners, might be challenged under healthcare fraud and abuse, anti-kickback, false claims or similar laws. Violations of the federal Physician Payment Sunshine Act and similar legislation or the fraud and abuse laws may be punishable by civil or criminal sanctions, including fines and civil monetary penalties, and future exclusion from participation in government healthcare programs. The principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and receive compensation in connection with such services. Under certain circumstances, we may be required to report some of these relationships to certain regulatory authorities, including the FDA and comparable foreign regulatory authorities. Consequently, the FDA or other regulatory authority may conclude that a financial relationship between us and a principal investigator creates a conflict of interest or otherwise affects interpretation of the study. In the event of a conflict of interest with respect to a study, the integrity of the data generated at the applicable clinical trial site may be questioned or the utility of the clinical trial itself may be jeopardized. This could result in a delay in approval, or rejection, of our marketing applications by the FDA or other regulatory authority, as the case may be, and may ultimately lead to the denial of marketing approval of one or more of our product candidates. The FDA and foreign regulatory authorities may also impose post-approval commitments on us for approved products, which we may not complete successfully or on time for any number of reasons, including, but not limited to, lack of funds to complete the studies and insufficient interest by appropriate sites, investigators or study subjects. We are currently subject to certain post-approval commitments and evolving FDA guidance. If we fail to comply with any post-approval legal and regulatory requirements, we could be subject to penalties, and our products could be subject to continual recordkeeping and reporting requirements, review and periodic inspections by the FDA and other regulatory bodies. Regulatory approval of a product may be subject to limitations on the indicated uses for which the product may be marketed or to other restrictive conditions of approval that limit our ability to promote, sell or distribute a product. Furthermore, the approval of our products and any other future product candidates may be subject to requirements for costly post-approval testing and surveillance to monitor their safety or efficacy or certain post-approval labeling, packaging and storage requirements. Advertising and promotion are subject to stringent oversight from the FDA and foreign regulators, and as a holder of an approved marketing application, we may be held responsible for any advertising and promotion that is not in compliance with applicable rules and regulations. Applicable regulatory authorities, competitors, and other third parties may take the position that we are not in compliance with such regulations. In addition to medical education efforts, we may offer patient support services to assist patients receiving treatment with our commercially approved products, and these support services have increasingly become the focus of government investigation. Adverse event information concerning approved products must be reviewed, and as a holder of an approved marketing application, we are required to make expedited and periodic adverse event reports to the FDA and other regulatory authorities. In addition, the research, manufacturing, distribution, sale and promotion of products are potentially subject to regulation by various federal, state and local authorities in addition to the FDA, including the Centers for Medicare and Medicaid Services (“CMS”), other divisions of HHS, the DOJ and individual U.S. Attorney offices within the DOJ, state and local governments, and foreign equivalents of the foregoing. All of these activities are also potentially subject to healthcare false claims and fraud and abuse laws, as well as consumer protection and unfair competition laws. If our operations with respect to our products that are subject to healthcare laws and regulations are found to be in violation of any of the healthcare fraud and abuse laws described above or in “Business—Government Regulation” in Part 62 Table of Contents I, Item 1 of our most recent Annual Report on Form 10-K or any other governmental regulations that apply to us, we may be subject to liability and penalties, including civil and criminal penalties, damages, fines, debarment or exclusion from participating in government-funded healthcare programs such as Medicare or Medicaid, and the curtailment or restructuring of our operations. Any penalties, damages, fines, debarment, exclusion, curtailment or restructuring of our operations could adversely affect our ability to operate our business and our financial results. Although compliance programs can mitigate the risk of investigation and prosecution for violations of these laws, the risks cannot be entirely eliminated. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. Moreover, achieving and sustaining compliance with all applicable fraud and abuse laws may be costly. We cannot predict the likelihood, nature or extent of government regulation or other measures that may arise from future legislation or administrative or executive action, either in the United States or abroad. The policies of the FDA and other regulatory authorities may change, including as a result of changes in presidential administration of the United States, and additional government regulations or executive orders may be enacted that could prevent, limit or delay regulatory approval of our product candidates, change our continuing compliance obligations, impact our product pricing and/or revenues, affect our supply chain or otherwise adversely affect our business. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained, we may not be able to obtain new marketing approvals, and we may not achieve sustained profitability. In addition, significant tariffs, trade measures or other restrictions imposed and related countermeasures taken by impacted foreign countries could adversely affect our operations and financial results. We cannot predict the likelihood, nature or extent of government regulation or other measures that may arise from future legislation or administrative or executive action, either in the United States or abroad. In June 2024, the Supreme Court overruled the Chevron doctrine, which had given deference to regulatory agencies’ statutory interpretations of ambiguous regulations in litigation against federal government agencies, such as the FDA. The overruling of the Chevron doctrine may significantly increase the number of challenges brought by companies and other stakeholders against federal agencies such as the FDA and its longstanding decisions and policies, including the FDA’s statutory interpretations of market exclusivities and the “substantial evidence” requirements for drug approvals, which could undermine the FDA’s authority, lead to uncertainties in the industry, and disrupt the FDA’s normal operations, any of which could delay the FDA’s review of regulatory submissions. We cannot predict the full impact of this decision, future judicial challenges brought against the FDA, or the nature or extent of government regulation that may arise from future legislation or administrative action. Further, under the new leadership at HHS under the current administration, agency reorganization, mass layoffs due to the reduction in force initiative and other measures may impact the normal operations of the FDA as well as other federal agencies. FDA may lack adequate staff and resources to meet current review, approval, and inspection schedules, which could delay our anticipated timelines. Recent developments at the FDA include announcement of a plan to phase out animal testing for monoclonal antibodies and certain other drugs, the proposed rare disease evidence principles (RDEP) program to facilitate approval of drugs to treat rare diseases with very small patient populations with significant unmet medical need and with a known genetic defect that is the major driver of the pathophysiology, and the announcement of a new Commissioner’s National Priority Voucher program for companies supporting certain U.S. national health priorities and interests. To the extent our competitors are selected for this new voucher pilot program, or are otherwise able to participate in any of these initiatives intended to accelerate drug development and application review, and obtain faster approval than us, our competitive position may be harmed. The FDA has also increased its scrutiny of foreign drug manufacturing facilities and other contractors based in China, especially with respect to the transfer of biological materials, genetic data, and other sensitive data of U.S. patients to parties located in China. It is unclear how our industry and our clinical programs will be impacted by policies and regulations implemented under the current administration and FDA leadership, or other executive orders. There is significant uncertainty in the industry and how federal agencies like the FDA will change in the coming years under the current administration. To the extent the agency reorganization and other agency changes lead to disruptions in the FDA’s operations, our correspondence and regulatory review processes with the FDA may be materially delayed. 63 Table of Contents Our employees, consultants and partners may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements, which could cause significant liability for us and harm our reputation. We are subject to the risk of fraud or other misconduct by our employees, consultants and partners, including intentional or unintentional failures to comply with FDA regulations or similar regulations of comparable other regulatory authorities, provide accurate information to the FDA or comparable other regulatory authorities, comply with manufacturing standards we have established, comply with federal and state healthcare fraud and abuse laws and regulations and similar laws and regulations established and enforced by comparable other regulatory authorities, report financial information or data accurately or disclose unauthorized activities to us. Employee and consultant misconduct could also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. It is not always possible to identify and deter employee and consultant misconduct, whether intentional, reckless, negligent, or unintentional, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws, standards or regulations. If any such actions are instituted against us and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business and results of operations, including the imposition of significant fines or other sanctions. We and our partners may be subject to new legislation, regulatory proposals and healthcare payor initiatives that may increase our costs of compliance and adversely affect our or our partners’ ability to commercialize our products or develop our product candidates. We are subject to new legislation, regulatory, and healthcare payor initiatives, including the Patient Protection and Affordable Care Act (“PPACA”), which made extensive changes to the delivery of healthcare in the United States, as discussed in “Business—Government Regulation” in Part I, Item 1 of our most recent Annual Report on Form 10-K. The continuing efforts of the government, insurance companies, managed care organizations and other payors of healthcare services to contain or reduce costs of healthcare could result in decreased net revenues from our pharmaceutical products and decrease potential returns from our development efforts. In addition, pharmaceutical and device manufacturers are also required to report and disclose certain payments and transfers of value to, and investment interests held by, physicians and their immediate family members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties for payments, transfers of value, or ownership or investment interests not reported in an annual submission. Compliance with the PPACA and state laws with similar provisions is difficult and time-consuming, and companies that do not comply with these state laws face civil penalties. Because of the breadth of these laws and the narrowness of the applicable safe harbors, it is possible that some of our business activities could be subject to challenge under one or more of such laws. Such a challenge could have a material adverse effect on our business, financial condition, results of operations and growth prospects. In addition, there have been a number of other legislative and regulatory proposals aimed at changing the pharmaceutical industry. For example, legislation has been enacted in certain states and at a federal level that requires manufacturers and other entities in the drug supply chain to track and trace each prescription drug at the saleable unit level through the distribution system. The FDA has finalized and proposed regulations implementing such requirements at a federal level. Our compliance with these requirements may be deemed insufficient and we could face a material adverse effect on our business, financial condition, results of operations and growth prospects. As a result of these and other new proposals, we may determine to change our current manner of operation, provide additional benefits or change our contract arrangements, any of which could have a material adverse effect on our business, financial condition and results of operations. Adequate coverage and reimbursement in the United States and other markets is essential to the commercial success of our approved products. Recently in the United States, there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products. For example, the Inflation Reduction Act of 2022 (“IRA”) implements a number of drug pricing measures intended to lower the cost of prescription drugs and related healthcare reforms, including limits on price increases and subjecting an escalating number of drugs to annual price negotiations with CMS. The IRA includes several provisions that will impact our business to varying degrees, including provisions that reduced the out-of-pocket spending cap for Medicare Part D beneficiaries to $2,100 in 2026; impose new manufacturer financial liability on all drugs in Medicare Part D; allow the U.S. Government to negotiate Medicare Part B and Part D pricing for certain high-cost drugs and biologics without generic or biosimilar competition; require companies to pay rebates to Medicare for drug prices that increase faster than inflation; and delay the rebate rule that would require pass through of pharmacy benefit manager rebates to beneficiaries. Further, under the IRA, orphan drugs are exempted from the 64 Table of Contents Medicare drug price negotiation program, but only if they have one orphan designation and for which the only approved indication or indications are for that disease or condition. If a product receives multiple rare disease designations or has multiple approved indications for more than one disease or condition, it may not qualify for the orphan drug exemption. In 2025, the U.S. Government took various steps, both legislative and executive, intended to lower the cost of prescription drugs. The President issued multiple executive orders and took other steps to secure pharmaceutical manufacturers’ agreements to lower certain U.S. prescription drug prices to most favored nation levels, to facilitate direct-to-patient sales of certain U.S. prescription drugs, and to secure agreements to repatriate increased ex-U.S. revenues generated as a result of U.S. Government action that increases drug prices outside the United States. On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was signed into law in the United States. The OBBBA contains a variety of provisions that could impact our business and results of operations. On January 15, 2026, the White House proposed that Congress enact the Great Healthcare Plan Act, which seeks to lower prescription drug and insurance prices. Multiple U.S. states have also enacted legislation intended to decrease the price of prescription drugs. We cannot be sure whether additional legislation or rule-making related to the IRA or drug pricing more generally will be issued or enacted, how insurance pharmacy benefit managers and other insurance providers that manage benefits for Medicare recipients will react to the IRA, or what impact, if any, such additional changes will have on the insurance coverage and profitability of our products or any of our product candidates, if approved for commercial use, in the future. The full effect of the IRA on our business and the healthcare industry in general is not yet known. The IRA or other government efforts to reduce the price of prescription drugs or to limit the amount that governments pay for healthcare products and services could result in additional pricing pressure and have a significant impact on our business. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs. Third-party payors are increasingly challenging the prices charged for medical products and services and, in some cases, imposing restrictions on the coverage of particular drugs. Many third-party payors negotiate the price of medical services and products and develop formularies which establish pricing and reimbursement levels. Exclusion of a product from a formulary can lead to its sharply reduced usage in the third-party payor’s patient population. The process for obtaining coverage can be lengthy and costly, and we expect that it could take several months before a particular payor initially reviews a product and makes a decision with respect to coverage. For example, third-party payors may require cost-benefit analysis data from us in order to demonstrate the cost-effectiveness of our products or any other product we might bring to market. For any individual third-party payor, we may not be able to provide data sufficient to gain reimbursement on a similar or preferred basis to competitive products, or at all, which may have a material adverse effect on our business, financial condition and results of operations. We may be subject to data privacy and security risks, and our actual or perceived failure to comply with regulations and other legal obligations related to privacy and data protection could harm our business. We may be subject to legal obligations at the international, federal, state, and local level related to privacy and data protection, as described in “Business—Government Regulation—Data Privacy and Security Laws” in Part I, Item 1 of our most recent Annual Report on Form 10-K. Compliance with stringent and evolving international and U.S. data protection laws and regulations could require us to take on more onerous obligations in our contracts, restrict our ability to collect, use, and disclose data, or in some cases, impact our ability to operate in certain jurisdictions. For example, we may be subject to the California Consumer Privacy Act (“CCPA”), which gives California residents expanded rights to access and require deletion of their personal data, opt out of certain personal data sharing, and receive detailed information about how their personal data is used. The CCPA provides for civil penalties of up to $7,500 per violation and allows private litigants affected by certain data breaches to recover significant statutory damages. Although the CCPA exempts some data processed in the context of clinical trials, the CCPA may increase compliance costs and potential liability with respect to other personal data we may maintain about California residents. We also may be subject to international privacy and data protection laws, such as the General Data Protection Regulation (“GDPR”) in the European Economic Area (“EEA”) and similar legislation in the United Kingdom and Switzerland. See “Business—Government Regulation—Data Privacy and Security Laws” in Part I, Item 1 of our most recent Annual Report on Form 10-K and “Risks Relating to Our Business—Risks Relating to International Operations—Our actual or perceived failure to comply with European or other international governmental laws and regulations and other legal obligations related to privacy, data protection and information security could harm our business” in this section for additional discussion of privacy laws and regulations. Failure to comply with these laws and regulations could result in government enforcement actions, private litigation, or harm to our reputation and our business. 65 Table of Contents Despite our efforts, our personnel or third parties on whom we rely may fail to comply with such data privacy and security obligations, which could negatively impact our business operations. If we or the third parties on which we rely fail, or are perceived to have failed, to address or comply with applicable data privacy and security obligations, we could face significant consequences, including, but not limited to, regulatory investigations or actions; litigation; fines and penalties; disruptions of our business operations; reputational harm; loss of revenue or profits; and other adverse business consequences. If, because of our use of hazardous materials, we violate any environmental controls or regulations that apply to such materials, we may incur substantial costs and expenses in our remediation efforts. Our research and development involves the controlled use of hazardous materials, chemicals and various radioactive compounds. We are subject to federal, state and local laws and regulations governing the use, storage, handling and disposal of these materials and some waste products. Accidental contamination or injury from these materials could occur. In the event of an accident, we could be liable for any damages that result, and any liabilities could exceed our resources. Compliance with environmental laws and regulations or a violation of such environmental laws and regulations could require us to incur substantial unexpected costs, which would materially and adversely affect our results of operations. Intellectual Property Risks If we fail to adequately protect or enforce our intellectual property rights, the value of those rights would diminish, and if we fail to secure the rights to patents of others, it could adversely affect our business. Our success will depend in part on our ability and the abilities of our partners to obtain, protect and enforce viable intellectual property rights including, but not limited to, trade name, trademark and patent protection for our Company and subsidiaries and the products, methods, processes and other technologies we may license or develop, to preserve our trade secrets, and to operate without infringing the proprietary rights of third parties both domestically and abroad. The patent position of biotechnology and pharmaceutical companies is generally highly uncertain, involves complex legal and factual questions and has recently been the subject of much litigation. Neither the United States Patent and Trademark Office (“USPTO”), the Patent Cooperation Treaty offices, nor the courts of the United States and other jurisdictions have consistent policies nor predictable rulings regarding the breadth of claims allowed or the degree of protection afforded under many biotechnology and pharmaceutical patents. Further, we may not have worldwide patent protection for all of our product candidates and our intellectual property rights may not be legally protected or enforceable in all countries throughout the world. In some jurisdictions, some of our product candidates in certain programs, including our HAE program, may have short or no composition of matter patent life and we may therefore rely on orphan drug exclusivity or data exclusivity. There can be no assurance that we will obtain orphan drug exclusivity or data exclusivity in every jurisdiction. Further, in some jurisdictions, we may rely on formulation patents or method of use patents. Both the ability to achieve issuance and the enforcement of formulation and method of use patents can be highly uncertain and can vary from jurisdiction to jurisdiction, and such patents may therefore not adequately prevent competitors and potential infringers in some jurisdictions. The validity, scope, enforceability, and commercial value of the rights protected by such patents, therefore, is highly uncertain. We also rely on trade secrets to protect technology in cases when we believe patent protection is not appropriate or obtainable. However, trade secrets are difficult to protect. In addition, increasing restrictions on non-compete agreements could increase the difficulty of protecting certain proprietary information. If we cannot maintain the confidentiality of our technology and other confidential information in connection with our collaborators and advisors, our ability to receive patent protection or protect our proprietary information may be imperiled. We may be involved in legal proceedings to protect or enforce our patents, the patents of our partners or our other intellectual property rights, which could be expensive, time-consuming and unsuccessful. Competitors may infringe or otherwise violate our patents, the patents of our licensors or our other intellectual property rights, or may design around our patent claims to produce competitive products that fall outside the scope of our patents. For example, a third party may develop a competitive drug that is similar to one or more of our products or product candidates but that has a different composition that falls outside the scope of our patent protection. To counter infringement or unauthorized use, we may be required to file legal claims, which can be expensive, time-consuming, and unsuccessful. An adverse result in any legal proceeding could put one or more of our patents at risk. Our success depends in part on avoiding the infringement of other parties’ patents and other intellectual property rights as well as avoiding the breach of any licenses relating to our technologies and products. In the United States, patent applications filed in recent years are confidential for 18 months after the earliest effective filing date, while older applications are not published until the patent issues. As a result, avoiding patent infringement may be difficult and we may inadvertently infringe third-party patents or 66 Table of Contents proprietary rights. These third parties could bring claims against us, our partners or our licensors that even if resolved in our favor, could cause us to incur substantial expenses and, if resolved against us, could additionally cause us to pay substantial damages. Further, if a patent infringement suit were brought against us, our partners or our licensors, we or they could be forced to stop or delay research, development, manufacturing or sales of any infringing product in the country or countries covered by the patent we infringe, unless we can obtain a license from the patent holder. Such a license may not be available on acceptable terms, or at all, particularly if the third party is developing or marketing a product competitive with the infringing product. Even if we, our partners or our licensors were able to obtain a license, the rights may be nonexclusive, which would give our competitors access to the same intellectual property. In addition, as described under “Business—Government Regulation—FDA Regulation—Abbreviated New Drug Applications for Generic Drugs” in Part I, Item 1 of our most recent Annual Report on Form 10-K, third parties may not file an ANDA for a generic drug with the FDA until the expiration of five years following the original product approval unless the submission is accompanied by a Paragraph IV certification, in which case third parties may submit an ANDA four years following the original product approval (referred to as the “NCE-1 date”). The NCE-1 date for ORLADEYO was in December 2024. In January 2025 and January 2026, we received a Paragraph IV notice of certification from Annora advising that Annora has submitted an ANDA to the FDA seeking approval to manufacture, use or sell a generic version of ORLADEYO in the United States prior to the expiration of four patents listed in the FDA’s Orange Book, which expire in May 2040. On March 10, 2025, as supplemented by the First Amended Complaint filed in December 2025, we filed a patent infringement lawsuit in the United States District Court for the District of Delaware against the Defendants (as defined in “Legal Proceedings” included in Part II, Item 1 of this report) asserting infringement of the challenged patents arising from Annora’s ANDA filing with the FDA. For further information, see the section titled “Legal Proceedings” included in Part II, Item 1 of this report and “Note 15—Commitments and Contingencies” in the Notes to the Condensed Consolidated Financial Statements in Part I, Item 1 of this report. We intend to vigorously defend our intellectual property rights protecting ORLADEYO. Additional third parties could challenge our applicable patents, which may result in our initiation of patent infringement litigation in response to such challenge. We cannot predict how any additional third party would address our listed patents, whether we would sue on any such patents, or the outcome of any such suit. However, litigation to enforce or defend intellectual property rights is complex, costly, and involves significant commitments of management’s time. If we or our partners are unable or fail to adequately initiate, protect, defend or enforce our intellectual property rights in any area of commercial interest or in any part of the world where we wish to seek regulatory approval for our products, methods, processes and other technologies, the value of our products and product candidates to produce revenue would diminish. Additionally, if our products, methods, processes, and other technologies or our commercial use of such products, processes, and other technologies, including, but not limited to, any trade name, trademark or commercial strategy infringe the proprietary rights of other parties, we could incur substantial costs. The USPTO and the patent offices of other jurisdictions have issued to us a number of patents for our various inventions, and we have in-licensed several patents from various institutions. We have filed additional patent applications and provisional patent applications with the USPTO. We have filed a number of corresponding foreign patent applications and intend to file additional foreign and U.S. patent applications, as appropriate. We have also filed certain trademark and trade name applications worldwide. We cannot assure you as to: •the degree and range of protection any patents will afford against competitors with similar products; •if and when patents will issue; •if patents do issue, we cannot be sure that we will be able to adequately defend such patents and whether or not we will be able to adequately enforce such patents; or •whether or not others will obtain patents claiming aspects similar to those covered by our patent applications. If the USPTO or other foreign patent office upholds patents issued to others or if the USPTO grants patent applications filed by others, we may have to: •obtain licenses or redesign our products or processes to avoid infringement; •stop using the subject matter claimed in those patents; or •pay damages. We may initiate, or others may bring against us, litigation or administrative proceedings related to intellectual property rights, including proceedings before the USPTO or other foreign patent office. Any judgment adverse to us in any litigation or other proceeding arising in connection with a patent or patent application could materially and adversely affect 67 Table of Contents our business, financial condition and results of operations. In addition, the costs of any litigation or administrative proceeding may be substantial whether or not we are successful. Our success is also dependent in part upon the skills, knowledge and experience, none of which is patentable, of our scientific and technical personnel. To help protect our rights, we require all employees, consultants, advisors and partners to enter into confidentiality agreements that prohibit the disclosure of confidential information to anyone outside of our Company and require disclosure and assignment to us of their ideas, developments, discoveries and inventions. These agreements may not provide adequate protection for our trade secrets, know-how or other proprietary information in the event of any unauthorized use or disclosure or the lawful development by others of such information, and if any of our proprietary information is disclosed, our business will suffer because our revenues depend upon our ability to license or commercialize our products and product candidates and any such events would significantly impair the value of such products and product candidates. We have diversified our pipeline to include the development of protein therapeutics, which may create additional risks and challenges. We have diversified our pipeline beyond small-molecule medicines to develop protein therapeutics. The development of protein therapeutics may create additional risks and challenges, including, among others: •patent protection for protein therapeutics may be narrower in scope than for our small-molecule medicines, and our patents and patent applications may not adequately protect our intellectual property, provide exclusivity for our protein therapeutic candidates or prevent others from designing around our claims; •formulation issues with our protein therapeutic candidates may require redevelopment of the formulation, which may be time-consuming or unsuccessful; •the patent applications that we own or in-license may fail to result in issued patents with claims that cover our protein therapeutic candidates in the United States or in other countries; •our competitors may be able to more easily develop and seek patent protection on similar protein therapeutic candidates; and •orally-administered drugs are often less expensive and present a reduced treatment burden as compared to protein therapeutics and therefore would have competitive advantages if they were developed and shown to be safe and effective for the indication that our protein therapeutic product candidates are targeting. Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our products. As is the case with other biotechnology and pharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and enforcing patents in the biotechnology and pharmaceutical industries involves both technological and legal complexity. Therefore, obtaining and enforcing such patents is costly, time-consuming, and inherently uncertain. In addition, the United States has recently enacted and is currently implementing wide-ranging patent reform legislation. Recent U.S. Supreme Court rulings have narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in certain situations. Additionally, there have been recent proposals for additional changes to the patent laws of the United States and other countries that, if adopted, could impact our ability to obtain patent protection for our proprietary technology or our ability to enforce our proprietary technology. Depending on future actions by the U.S. Congress, the U.S. courts, the USPTO and the relevant law-making bodies in other countries, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future. We may be subject to claims that our employees, consultants, or independent contractors have wrongfully used or disclosed confidential information of third parties or that our employees have wrongfully used or disclosed alleged trade secrets of their former employers. We employ certain individuals who were previously employed at universities or other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Our efforts to vet our employees, consultants, and independent contractors and prevent their use of the proprietary information or know-how of others in their work for us may not be successful, and we may in the future be subject to claims that our employees, consultants, or independent contractors have wrongfully used or disclosed confidential information of third parties. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel, which could adversely impact our business. Even if we are successful in defending against such claims, litigation could result in substantial costs and distract management and other employees. 68 Table of Contents Product Liability Risks We face an inherent risk of liability in the event that the use or misuse of our products or product candidates results in personal injury or death, and our product liability insurance coverage may be insufficient. If the use or misuse of any products we sell, or a partner sells, harms people, we may be subject to costly and damaging product liability claims brought against us by consumers, healthcare providers, pharmaceutical companies, third-party payors or others. The use of our product candidates in clinical trials, including post-marketing clinical studies, could also expose us to product liability claims. We cannot predict all of the possible harms or side effects that may result from the use of our products or the testing of product candidates, and therefore, the amount of insurance coverage we currently have may not be adequate to cover all liabilities or defense costs we might incur. A product liability claim or series of claims brought against us could give rise to a substantial liability that could exceed our resources. Even if claims are not successful, the costs of defending such claims and potential adverse publicity could be harmful to our business. We face an inherent risk of product liability exposure related to the testing of our product candidates in human clinical trials and face even greater risks upon commercialization by us of our products or product candidates. We have product liability insurance covering our clinical trials. Clinical trial and product liability insurance is becoming increasingly expensive. As a result, we may be unable to obtain sufficient insurance or increase our existing coverage at a reasonable cost to protect us against losses that could have a material adverse effect on our business. An individual may bring a product liability claim against us if one of our products or product candidates causes, or is claimed to have caused, an injury or is found to be unsuitable for consumer use. Any product liability claim brought against us, with or without merit, could result in: •liabilities that substantially exceed our product liability insurance, which we would then be required to pay from other sources, if available; •an increase of our product liability insurance rates or the inability to maintain insurance coverage in the future on acceptable terms, or at all; •the withdrawal of clinical trial volunteers or patients; •damage to our reputation and the reputation of our products, resulting in lower sales; •regulatory investigations that could require costly recalls or product modifications; •litigation costs; and •the diversion of management’s attention from managing our business. Risks Relating to Contractual Arrangements We may face risks related to our former U.S. Government contracts. We had contracts with the Biomedical Advanced Research and Development Authority within HHS and the National Institute of Allergy and Infectious Diseases within HHS for the development of galidesivir as a treatment for diseases caused by RNA pathogens, including Marburg virus disease, Yellow Fever and Ebola virus disease. In contracting with U.S. Government agencies, we became subject to various U.S. Government contract requirements, including general clauses for a cost-reimbursement research and development contract, which may limit our reimbursement. While all U.S. Government funding for galidesivir expired in 2022, we may still face risks related to these U.S. Government contracts pending final close out of these contracts. If we fail to reach milestones or to make annual minimum payments or otherwise breach our obligations under our license agreements, our licensors may terminate our agreements with them and/or seek additional remedies. If we are unable or fail to meet payment obligations, performance milestones relating to the timing of regulatory filings, product supply obligations, post-approval commitments, or development and commercial diligence obligations; are unable or fail to make milestone payments or material data use payments in accordance with applicable provisions; or fail to pay the minimum annual payments under any of our in-licenses relating to our products or product candidates, our licensors may terminate the applicable license and/or seek other available remedies. As a result, our development of the respective product candidate or commercialization of the product would cease. Because continuing events of default exist under the PhaRMA Notes, the holders of the PhaRMA Notes may be able to foreclose on the collateral securing the PhaRMA Notes and our equity interest in Royalty Sub. As a result, we may not 69 Table of Contents realize the benefit of future royalty payments, if any, that might otherwise accrue to us following repayment of the PhaRMA Notes and we could otherwise be adversely affected. In March 2011, JPR Royalty Sub LLC, our wholly owned subsidiary (“Royalty Sub”), issued $30.0 million in aggregate principal amount of PhaRMA Senior Secured 14.0% Notes due on December 1, 2020 (the “PhaRMA Notes”). The PhaRMA Notes are secured principally by (i) certain royalty and milestone payments under our agreement with Shionogi, pursuant to which Shionogi licensed from us the rights to market peramivir in Japan and Taiwan and (ii) the pledge by us of our equity interest in Royalty Sub. Since September 1, 2014, payments from Shionogi have been insufficient for Royalty Sub to service its obligations under the PhaRMA Notes, resulting in a continuing event of default with respect to the PhaRMA Notes since that time. In addition, the PhaRMA Notes had a final legal maturity date of December 1, 2020, at which time the outstanding principal amount of the PhaRMA Notes of $30.0 million, together with accrued and unpaid interest of $20.6 million, was due in full. The failure by Royalty Sub to repay these amounts at the maturity date constituted an additional event of default under the PhaRMA Notes. As Royalty Sub has been unable to service its obligations under the PhaRMA Notes and continuing events of default exist under the PhaRMA Notes, the holders of the PhaRMA Notes may be able to foreclose on the collateral securing the PhaRMA Notes and our equity interest in Royalty Sub and may exercise other remedies available to them under the indenture or other documents related to the PhaRMA Notes. In such event, we may not realize the benefit of future royalty payments, if any, that might otherwise accrue to us following repayment of the PhaRMA Notes, we may incur legal costs, and we might otherwise be adversely affected. We cannot predict whether holders of PhaRMA Notes will seek to pursue any remedies as a result of the continuing events of default with respect to the PhaRMA Notes. The PhaRMA Notes are the obligation of Royalty Sub. Due to the non-recourse nature of the PhaRMA Notes, in the event of any potential foreclosure, we believe the primary impact to us would be the loss of future royalty payments, if any, from Shionogi and the legal costs associated with retiring the PhaRMA Notes. As a result, we do not currently expect the continuing events of default on the PhaRMA Notes to have a significant impact on our future results of operations or cash flows. However, we cannot assure you that this will be the case or that we will not otherwise be adversely affected as a result of the continuing events of default under the PhaRMA Notes or the failure by Royalty Sub to repay the PhaRMA Notes at maturity. While Royalty Sub continues to pay the holders of the PhaRMA Notes any royalty payments received from Shionogi, which are immaterial, we wrote off the balance due under the PhaRMA Notes to other income as a debt extinguishment as of December 31, 2021. We have incurred significant indebtedness, which could adversely affect our business. Additionally, the Blackstone Loan Agreement contains conditions and restrictions that limit our flexibility in operating our business. We may be required to make a prepayment or repay our outstanding indebtedness earlier than we expect if a prepayment event or an event of default occurs, including a material adverse change with respect to us, which could have a material adverse effect on our business. On January 23, 2026, we entered into the Blackstone Loan Agreement, pursuant to which the lenders funded initial term loans in the aggregate principal amount of $400.0 million. Subject to the mutual agreement between the Company, Blackstone and the lenders, we may request additional term loans up to an aggregate amount not exceeding $150.0 million. Under the Blackstone Loan Agreement, we will be required to pay to the lenders a prepayment premium or a make-whole premium, as applicable, in the event that, prior to the fourth anniversary of the closing date of the Blackstone Loan Agreement, we prepay or repay, or are required to prepay or repay, voluntarily or pursuant to a mandatory prepayment obligation under the Blackstone Loan Agreement (e.g., upon certain asset sales, a change of control of the Company and specified other events, subject to certain exceptions), all or part of the then-outstanding term loans under the Blackstone Loan Agreement, in each case, subject to certain exceptions as set forth in the Blackstone Loan Agreement. Our indebtedness could have important consequences to our stockholders. For example, it: •increases our vulnerability to adverse general economic or industry conditions; •limits our flexibility in planning for, or reacting to, changes in our business or the industry in which we operate; •makes us more vulnerable to increases in interest rates, as borrowings under the Blackstone Loan Agreement will accrue interest at variable rates, such that increases in interest rates will increase the associated interest payments that we are required to make on outstanding borrowings; •requires us to dedicate a portion of our cash flow from operations to interest payments and a covenant to maintain minimum liquidity levels, limiting the availability of cash for other purposes; 70 Table of Contents •limits our ability to obtain additional financing or refinancing in the future for working capital or other purposes; and •places us at a competitive disadvantage compared to our competitors that have less indebtedness. Furthermore, the Blackstone Loan Agreement contains covenants that limit our ability to engage in specified types of transactions. Subject to certain exceptions, these covenants limit our ability to, among other things, dispose of assets; engage in certain mergers, acquisitions, and similar transactions; incur additional indebtedness; grant liens; make investments; pay dividends or make distributions or certain other restricted payments in respect of equity; prepay other indebtedness; enter into restrictive agreements; undertake fundamental changes; or amend certain material contracts. The covenants contained in the Blackstone Loan Agreement could cause us to be unable to pursue business opportunities that we or our stockholders may consider beneficial without the lenders’ permission or without repaying all outstanding obligations under the Blackstone Loan Agreement. A breach of any of these covenants could result in an event of default under the Blackstone Loan Agreement. An event of default will also occur if, among other things, we fail to pay amounts due under the Blackstone Loan Agreement, we fail to repay certain other indebtedness having an aggregate principal amount in excess of a threshold amount, an insolvency event occurs with respect to us, judgments for the payment of money in excess of a threshold amount are entered into against us, or a material impairment of our ability to perform our obligations under the Blackstone Loan Agreement occurs or certain negative regulatory events occur. In the case of a continuing event of default under the Blackstone Loan Agreement, the lenders under the Blackstone Loan Agreement could elect to declare all amounts outstanding to be immediately due and payable, proceed against the collateral in which we granted to the lenders a security interest, or otherwise exercise the rights of a secured creditor. Amounts outstanding under the Blackstone Loan Agreement are secured by a security interest in, subject to certain exceptions, substantially all of our assets. Because substantially all of our assets are pledged to secure the Blackstone Loan Agreement obligations, our ability to incur additional secured indebtedness or to sell or dispose of assets to raise capital may be impaired, which could have an adverse effect on our financial flexibility. Risks Relating to International Operations International expansion of our business exposes us to business, legal, regulatory, political, operational, financial, and economic risks. We currently conduct clinical studies and regulatory activities and have hired employees outside of the United States. Doing business internationally involves a number of risks, including, but not limited to: •multiple, conflicting, and changing laws and regulations such as privacy and data regulations, transparency regulations, tax laws, export and import restrictions, employment laws, regulatory requirements, and other governmental approvals, permits, and licenses; •introduction of new health authority requirements and/or changes in health authority expectations; •failure by us or our partners to obtain and maintain regulatory approvals for the use of our products in various countries; •complexities and difficulties in obtaining and maintaining protection for, and enforcing, our intellectual property; •difficulties in staffing and managing foreign operations; •complexities associated with managing multiple payor reimbursement regimes, government payors, or patient self-pay systems; •limits on our ability to penetrate international markets; •financial risks, such as longer payment cycles, difficulty collecting accounts receivable, the impact of local and regional financial crises on demand and payment for our products, and exposure to foreign currency exchange rate fluctuations, which have been increasingly prevalent alongside a fluctuating U.S. dollar; •natural disasters and political and economic instability, including wars, terrorism, political unrest, results of certain elections and votes, actual or threatened public health emergencies and outbreak of disease, epidemics or pandemics (e.g., the COVID-19 pandemic), boycotts, adoption or expansion of government trade restrictions, and other business restrictions; •certain expenses including, among others, expenses for travel, translation, and insurance; •regulatory and compliance risks that relate to maintaining accurate information and control over commercial operations and activities that may fall within the purview of the U.S. Foreign Corrupt Practices 71 Table of Contents Act, including its books and records provisions or anti-bribery provisions, and foreign laws and regulations; and •regulatory and compliance risks relating to doing business with any entity that is subject to sanctions administered by the Office of Foreign Assets Control of the U.S. Department of the Treasury. Any of these factors could significantly harm our international expansion of operations and adversely affect our business and results of operations. Additionally, in some countries, such as Japan, the pricing of prescription pharmaceuticals is subject to governmental control and access. In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. To obtain reimbursement or pricing approval in some countries, we or our partners may be required to conduct a clinical trial that compares the cost-effectiveness of our product to other available therapies. If reimbursement of our products is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our business could be materially harmed. Foreign currency exchange rate fluctuations could have an adverse impact on our results of operations, financial position, and cash flows. We conduct operations in countries outside of the United States involving transactions in a variety of currencies other than the U.S. dollar. These transactions include, without limitation, commercial sales, contract manufacturing, and clinical trial activities. Although most of our revenues and expenses are denominated in U.S. dollars, we have foreign currency exposure to fluctuations in other foreign currencies, such as the Euro, Japanese Yen and Canadian Dollar. Changes in the value of these currencies relative to the U.S. dollar may impact our condensed consolidated operating results, including our revenues and expenses, causing fluctuations in our operating results from period to period and/or resulting in foreign currency transaction losses that adversely impact our results of operations, financial position, and cash flows. See “Quantitative and Qualitative Disclosures about Market Risk—Foreign Currency Risk” in Part I, Item 3 of this report for additional information about our foreign currency risk. Our actual or perceived failure to comply with European or other international governmental laws and regulations and other legal obligations related to privacy, data protection and information security could harm our business. Outside the United States, an increasing number of laws and regulations may govern data privacy and security. EU member states, the United Kingdom, Switzerland and other countries have adopted data protection laws and regulations, which impose significant compliance obligations. These laws include the GDPR and similar national legislation within the EEA, the United Kingdom GDPR, Switzerland’s Federal Data Protection Act, the EU Clinical Trials Regulation, and the e-Privacy Directive (2002/58/EC), as well as laws and regulations outside Europe, and are discussed in more detail in “Business—Government Regulation—Data Privacy and Security Laws” in Part I, Item 1 of our most recent Annual Report on Form 10-K. Failure to comply with the requirements of these laws may result in significant fines. For example, noncompliance with the GDPR or related national data protection laws, which may deviate from the GDPR, may result in significant fines of up to 4.0% of global revenues, or €20.0 million, whichever is greater. In addition to such fines, failure to comply with the requirements of the GDPR or similar national legislation may result in temporary or definitive bans on data processing and other corrective actions and subject us to litigation and/or adverse publicity, which could have material adverse effects on our reputation and business. As a result of the implementation of the GDPR, and other laws and regulations, we are required to put in place additional mechanisms to ensure compliance with the data protection rules. For example, the GDPR requires us to make more detailed disclosures to data subjects, requires disclosure of the legal basis on which we can process personal data, makes it harder for us to obtain valid consent for processing, requires the appointment of a data protection officer where sensitive personal data (i.e., health data) is processed on a large scale, introduces mandatory data breach notification throughout the European Union, imposes additional obligations on us when we are contracting with service providers and requires us to adopt appropriate privacy governance including policies, procedures, training and data audits. We depend on a number of third parties in relation to the provision of our services, a number of which process personal data of EU individuals on our behalf. With each such provider, we are required to enter into contractual arrangements under which they are contractually obligated to only process personal data according to our instructions, and conduct diligence to ensure that they have sufficient technical and organizational security measures in place. Other laws and regulations have requirements that are similar, and in some instances more far-reaching. Compliance with evolving laws regarding the transfer of personal data to the United States and other countries also requires increased resources and may result in increased exposure to regulatory actions, fines and penalties, the inability to transfer data and work with partners, vendors and other third parties, and injunctions against our processing or transferring 72 Table of Contents of personal data necessary to operate our business. We are also subject to evolving European and other privacy laws on electronic marketing and cookies. Compliance with the requirements imposed by the GDPR and other such laws can be time-consuming, expensive and difficult, and may increase our cost of doing business or require us to change our business practices, and despite our efforts we may not be successful in achieving compliance if our personnel, collaborators, partners or vendors do not comply with applicable data protection obligations. Despite our efforts, our personnel or third parties on whom we rely may fail to comply with such obligations, which could negatively impact our business operations. If we or the third parties on which we rely fail, or are perceived to have failed, to address or comply with applicable data privacy and security obligations, we could face significant consequences, including but not limited to: regulatory investigations or actions; litigation; fines and penalties; disruptions of our business operations; reputational harm; loss of revenue or profits; and other adverse business consequences. Risks Relating to Technology If our facilities, or the facilities of our third-party vendors, incur damage or power is lost for a significant length of time, our business will suffer. We and our third-party vendors store commercial product, clinical and stability samples, and manufacturing data at our facilities that could be damaged if the facilities incur physical damage or in the event of an extended power failure. We have backup power systems in addition to backup generators to maintain power to all critical functions, but any loss of these products or samples could result in significant delays in our commercialization or product development process. In addition, we store most of our preclinical and clinical data at our facilities. While duplicate copies of most clinical data are secured off-site, and a significant portion of our data is included in regular backups of our systems, we could lose important data if our facilities incur damage, or if our vendor data systems fail, suffer damage or are destroyed. Any significant degradation or failure of our computer systems could cause us to inaccurately calculate or lose our data. Loss of data could result in significant delays in our product development process, and any system failure could harm our business and operations. Cyber incidents and related disruptions in our or our third-party vendors’ information technology systems could adversely affect our business. We are increasingly dependent on information technology systems to operate our business. In addition, the FDA and other U.S. and foreign regulatory authorities regulate, among other things, the record keeping and storage of data pertaining to potential pharmaceutical products. Like other companies in our industry, our information technology systems and infrastructure (as well as those of our third-party providers) and our lab equipment and operations technology may be vulnerable to cyber incidents, intrusions, and other similar activities that threaten the confidentiality, integrity, and availability of our information. These threats come from a variety of sources, including by computer hackers, foreign governments, foreign companies, or competitors, or may be breached by employee error, malfeasance or other disruption. These threats are prevalent, continue to rise, and are becoming increasingly difficult to detect. Recently, there have been reports of disruptions in billing and data systems in healthcare. Such cybersecurity events which materially disrupt the healthcare system upon which our business relies could adversely affect our business if such disruption is widespread and continues for an extended period of time. Cyber incidents could also include the use of artificial intelligence (“AI”) and machine learning to launch more automated, targeted and coordinated attacks on targets. Cyber incidents may lead to operational outages, loss of intellectual property due to industrial espionage, malware, and financial or data attacks via social engineering. These risks are heightened by the wide adoption of virtual and remote working, with sensitive data accessed by employees working in less secure, home-based environments, as well as the increasing use of generative AI by both employees and third parties. A breakdown, invasion, corruption, destruction, or interruption of information technology systems could negatively impact operations. If our systems are damaged, fail to function properly or otherwise become unavailable, we may incur substantial costs to repair or replace them, and we may experience loss of critical data and interruptions or delays in our ability to perform critical functions, which could adversely affect our business, financial condition or results of operations. In addition, we rely on third-party service providers and technologies to operate significant information technology systems and business infrastructure, and we currently use these providers to perform business critical information technology and business services. Supply-chain attacks have increased in frequency and severity, and we cannot guarantee that third parties’ infrastructure in our supply chain or our third-party partners’ supply chains have not been or will not be compromised. 73 Table of Contents We have experienced cybersecurity threats and incidents, which to date have not had a material impact on our reputation, business, financial condition, or operations; however, there is no assurance that such impacts will not be material in the future. Any compromise of our data security could also result in a violation of applicable privacy and other laws, significant legal, regulatory, and financial exposure, damage to our reputation, loss or misuse of the information and a loss of confidence in our data security measures, which could harm our business. Loss or misuse of our intellectual property, clinical trial data, or commercially sensitive data could adversely impact our business. While we have implemented security measures designed to protect against security incidents and a significant portion of our data is included in regular backups of our systems, there can be no assurance that our efforts to protect our data and information technology systems will prevent breakdowns or breaches in our systems, or those of third parties with which we do business, and any such events could adversely affect our business. We use AI in our business, and challenges with properly managing its use could adversely affect our business. The increasing use of AI and machine learning technology in the biopharmaceutical industry, combined with an uncertain regulatory environment, presents new risks and challenges. We have adopted and integrated certain AI solutions into our ecosystem, and applications of AI may become increasingly more important in our operations over time. Our vendors may incorporate AI tools into their offerings without disclosing this use to us, and the providers of these tools may not meet existing or rapidly evolving regulatory or industry standards with respect to privacy and data protection. Moreover, the use of AI-based tools may lead to the inadvertent release of confidential or proprietary information, which may adversely impact our ability to realize the benefit of our intellectual property, cause us to incur liabilities as the result of any breaches of confidentiality, impact our ability to comply with data security and privacy laws, and introduce additional cybersecurity risks. Further, as the regulatory framework for these technologies evolves, it is possible that new laws and regulations will be adopted, or that existing laws and regulations may be interpreted in ways that would affect our business, including as a result of the cost to comply with such laws or regulations. Our competitors or other third parties may also incorporate AI into their businesses more efficiently than us, which could impair our ability to compete effectively and adversely affect our results of operations. The rapid innovation and developments surrounding AI, including potential government regulation of AI, may require significant resources to develop, test and maintain our implementations of AI. Other Operational Risks Our ability to maintain global brand uniformity for ORLADEYO may be impacted by the sale of our European ORLADEYO business. In connection with the sale of our European ORLADEYO business, we entered into the Global Brand and Support Agreement, which provides for coordination of brand and regulatory activities regarding ORLADEYO products. While this agreement is intended to promote alignment on brand and related activities with Neopharmed, we do not have sole control over how ORLADEYO is positioned, supported or communicated in Europe, and we may not be able to maintain global brand uniformity with respect to ORLADEYO. This risk may be heightened given that ORLADEYO is indicated for a rare disease with a limited number of key opinion leaders and relatively few scientific publications or forums that reach a broad global audience. If we are unable to maintain a consistent and effective global brand presence for ORLADEYO, our ability to maximize the anticipated benefits of the sale, support future growth and realize the expected long‑term value of ORLADEYO could be adversely affected. Health epidemics or pandemics could materially adversely affect our business, operations, clinical development or commercialization plans and timelines, or that of third parties with whom we conduct business, including, without limitation, our development partners, manufacturers, CROs, and others, as well as the regulatory and government agencies with whom we work. A health epidemic or pandemic, such as the COVID-19 pandemic, and related government orders or responsive business policies and procedures, could cause disruptions to our business, operations, and clinical development or commercialization plans and timelines, as well as the business and operations of third parties with whom we conduct business. If our operations or those of third parties with whom we conduct business, such as development partners, manufacturers, CROs and others, are impaired or curtailed as a result of such events, the development and commercialization of our products and product candidates could be stopped or delayed, or the costs of such development and commercialization activities could increase, any of which could have a material adverse impact on our business. For 74 Table of Contents example, our suppliers or other vendors may be unable to meet their obligations to us or perform their services as expected. In such circumstances, we may not be able to enter into arrangements with alternative suppliers or vendors or do so on commercially reasonable terms or in a timely manner. Such delays could adversely impact our ability to meet our desired clinical development and any commercialization timelines. In addition, our clinical trials were affected by the COVID-19 pandemic, and we may experience similar delays or interruptions due to health epidemics or pandemics in the future, which could adversely impact our clinical trial operations. Health epidemics or pandemics could also affect the operations of regulators and other health and governmental authorities, which could result in delays of reviews and approvals, inspections, or other regulatory activities. The global impact of a health epidemic or pandemic, such as the COVID-19 pandemic, could also materially affect global economies and financial markets, which could reduce our ability to access the equity or debt capital markets or obtain other sources of capital if needed, which could negatively affect our liquidity. In addition, a recession or market correction could materially affect our business and the value of our common stock. Health epidemics or pandemics could also have the effect of heightening many of the other risks described in this report. Our business, operations, clinical development or commercialization plans and timelines, and access to capital could be adversely affected by unpredictable and unstable market and economic conditions. Our business, operations, clinical development or commercialization plans and timelines, and access to capital could be adversely affected by unpredictable and unstable market and economic conditions, including as a result of inflation, increased interest rates, disruption or instability in the banking industry, foreign exchange rate fluctuations, U.S. Government shutdowns, instability in connection with changes in the presidential administration in the United States, geopolitical instability, actual or threatened public health emergencies, or outbreaks of disease, epidemics or pandemics (such as the COVID-19 pandemic). The magnitude, duration and long-term effect of each of these factors, as well as the effects of actions taken by governments to address them, are unknown at this time, but they could result in further significant disruption of the global economy and financial markets. Our business may be adversely affected by any related economic downturn, volatile geopolitical and business environment, or continued market instability. Unstable market and economic conditions could materially affect our ability to access the equity or debt capital markets or obtain other sources of capital if needed in the future, which could negatively affect our liquidity. In addition, a recession or market correction could materially affect our business and the value of our common stock. Market and economic conditions continue to evolve, with the ultimate impacts being uncertain and subject to change. These effects could be material, and we will continue to monitor the economic climate closely. We do not know the full extent and magnitude of the impacts that any future developments will have on our business, on the healthcare system, or on the global economy. In addition, unstable market conditions could have the effect of heightening many of the other risks described in this report. Insurance coverage is increasingly more costly and difficult to obtain or maintain. While we currently have insurance for our business, property, directors and officers, and our products, insurance is increasingly more costly and narrower in scope, and we may be required to assume more risk in the future. If we are subject to claims or suffer a loss or damage in excess of our insurance coverage, we will be required to bear any loss in excess of our insurance limits. If we are subject to claims or suffer a loss or damage that is outside of our insurance coverage, we may incur significant uninsured costs associated with loss or damage that could have an adverse effect on our operations and financial position. Furthermore, any claims made on our insurance policies may impact our ability to obtain or maintain insurance coverage at reasonable costs or at all. If we fail to retain our existing key personnel or fail to attract and retain additional key personnel, the development of our product candidates, the commercialization of our products, and the related growth of our business may be delayed or stopped. The unexpected loss of service of our senior management and other key personnel might impede the achievement of our development and commercial objectives. Competition for key personnel with the experience that we require is intense and is expected to continue to increase. Our inability to attract and retain the required number of skilled and experienced management, commercial, operational and scientific personnel may harm our business because we rely upon these personnel for many important functions of our business. 75 Table of Contents If our risk management committee and other compliance methods are not effective, our business, financial condition and operating results may be adversely affected. Our ability to identify, manage and respond to the various risks related to our business is largely dependent on our established and maintained compliance, risk, audit and reporting systems and procedures. The Board of Directors has ultimate responsibility for risk oversight of the Company and carries out this duty through its committees. The Board of Directors may delegate oversight authority with respect to certain issues in a committee’s applicable areas of expertise. At the Company level, our senior management team similarly monitors risk through the risk management committee and other sub-committees focused on specific areas of risk (e.g., cybersecurity, quality assurance). Membership of the risk management committee consists primarily of key department heads who are asked to bring to such committee relevant items for discussion that they or their teams have identified at the numerous sub-committees these individuals chair or attend. The risk management committee, along with the other sub-committees in the Company, identifies key risks and mitigation strategies which are reported directly to our senior management, the Audit Committee and to the full Board of Directors on a regular basis. If our policies, procedures, and compliance systems, including our risk management committee, are not effective, or if we are not successful in monitoring or evaluating the risks to which we are or may be exposed, our business, reputation, financial condition and operating results could be materially adversely affected. We cannot provide assurance that our policies and procedures will always be effective, or that our management or the risk management committee would be able to identify any such ineffectiveness. If our compliance and risk management strategies are not effective, our business, financial condition and operating results may be adversely affected. Future acquisitions, strategic investments, partnerships, alliances, or divestitures could be difficult to identify and integrate, divert the attention of management, disrupt our business, dilute stockholder value, materially change the risk profile of the Company and could fail to meet our expectations, any of which could adversely affect our operating results and financial condition. We will seek to acquire or invest in businesses, products or technologies that we believe could complement or expand our portfolio or otherwise offer growth opportunities. The pursuit of potential acquisitions may divert the attention of management and cause us to incur various expenses in identifying, investigating and pursuing businesses or products. In addition, we may not be able to find and identify desirable acquisition targets or be successful in entering into an agreement with any particular target or consummating any such agreement. Even if we do consummate an acquisition, in connection therewith we may be required to issue equity (thereby diluting our current stockholders) or debt, we may not be able to integrate successfully the acquired personnel, operations and technologies, or effectively manage the combined business following the acquisition, or the acquired business could otherwise fail to meet our expectations, which, in each case, could have a material adverse effect on our business projections, financial condition, results of operations and prospects. Our strategic shift toward external innovation, including in connection with the Birmingham Closure Plan, may increase our reliance on acquisitions, strategic investments, partnerships or other business development transactions to expand our product candidate pipeline. We may not identify suitable opportunities, complete transactions on acceptable terms or at all, or realize the anticipated operational, financial or strategic benefits of any such transactions or related initiatives on the expected timeline or at all. Additionally, actual costs of the Birmingham Closure Plan may exceed our estimates, anticipated savings may not be realized or may be offset by costs associated with external innovation, business development, acquired or licensed programs or other strategic priorities, and the closure of our Birmingham facility and related workforce reduction may result in the loss of institutional knowledge or technical expertise, adversely affect employee morale or retention, divert management attention or disrupt our operations. If we do not execute this strategy effectively, our business, financial condition, results of operations, liquidity and ability to execute our strategic priorities could be adversely affected. In addition, we may divest or license all or a portion of certain business or product categories, which could cause a decline in revenue or profitability and may make our financial results more volatile. We may be unable to complete any such divestiture or license on terms favorable to us, within the expected timeframes, or at all, in which case we may not realize any return on our investment in these programs and may incur costs associated with their termination. For example, after evaluating potential partnering opportunities for the continued development of avoralstat, we determined in the quarter ended March 31, 2026 to terminate the avoralstat program to focus the pipeline on rare diseases. We may have continued financial exposure to divested or licensed businesses following the completion of any such transactions, including increased costs due to potential litigation, contingent liabilities and indemnification of the buyer or licensee related to, among other things, lawsuits, regulatory matters or tax liabilities. Such divestitures or licenses may also divert management’s attention from our core businesses and lead to potential issues with employees, customers or suppliers. 76 Table of Contents Our business and operations could be negatively affected if we become subject to stockholder activism or hostile bids, which could cause us to incur significant expense, hinder execution of our business strategy and impact our stock price. Stockholder activism, which takes many forms and arises in a variety of situations, has been increasingly prevalent. Stock price declines may also increase our vulnerability to unsolicited approaches. If we become the subject of certain forms of stockholder activism, such as proxy contests or hostile bids, the attention of our management and our Board of Directors may be diverted from execution of our strategy. Such stockholder activism could give rise to perceived uncertainties as to our future strategy, adversely affect our relationships with business partners and make it more difficult to attract and retain qualified personnel. Also, we may incur substantial costs, including significant legal fees and other expenses, related to activist stockholder matters. Our stock price could be subject to significant fluctuation or otherwise be adversely affected by the events, risks and uncertainties of any stockholder activism. Risks Relating to Investing in Our Common Stock Our existing principal stockholders hold a substantial amount of our common stock and may be able to influence significant corporate decisions, which may conflict with the interest of other stockholders. Some of our stockholders own greater than 5% of our outstanding common stock. Our top ten stockholders own approximately 50% of our common stock and can individually, and as a group, influence our operations based upon their concentrated ownership and may also be able to influence the outcome of matters requiring approval of the stockholders, including the election of our directors and other corporate actions. Our stock price has been, and is likely to continue to be, highly volatile, which could cause the value of an investment in our common stock to decline significantly. The market prices for securities of biotechnology companies in general have been highly volatile and may continue to be highly volatile in the future. Moreover, our stock price has fluctuated frequently, and these fluctuations are often not related to our financial results. For the twelve months ended June 30, 2026, the 52-week range of the market price of our stock was from $6.00 to $10.94 per share. The following factors, in addition to other risk factors described in this section, may have, and in some cases have had, a significant impact on the market price of our common stock: •announcements of technological innovations or new products by us or our competitors; •developments or disputes concerning patents or proprietary rights; •additional dilution through sales or issuances of our common stock or other derivative securities; •status of new or existing licensing or collaborative agreements and government contracts; •announcements relating to the status of our programs or changes to our operations or business strategy (such as the Birmingham Closure Plan); •us or our partners achieving or failing to achieve development milestones; •publicity regarding actual or potential medical results relating to products under development by us or our competitors; •publicity regarding certain public health concerns for which we are or may be developing treatments; •regulatory developments in both the United States and foreign countries; •public concern as to the safety of pharmaceutical products; •actual or anticipated fluctuations in our operating results; •changes in financial estimates or recommendations by securities analysts and the comparison of such estimates to our actual results; •online automated financial platforms’ treatment or classification of our financial information; •changes in our public guidance; •changes in the structure of healthcare payment systems, including developments in price control legislation; •announcements by us or our competitors of significant acquisitions (such as the Merger), strategic partnerships, divestitures (such as the sale of our European ORLADEYO business to Neopharmed), joint ventures, capital commitments or other monetization transactions; •additions or departures of key personnel or members of our Board of Directors; •purchases or sales of substantial amounts of our stock by existing stockholders, including officers or directors; •economic and other external factors or other disasters or crises; and •period-to-period fluctuations in our financial results. This volatility could cause the value of an investment in our common stock to decline significantly. In addition, companies that have experienced volatility in the market price of their stock in the past have been subject to securities class 77 Table of Contents action litigation. Securities litigation, and any other type of litigation, brought against us could result in substantial costs and divert our management’s attention from other business concerns, which could seriously harm our business and adversely affect our results of operations. If we fail to maintain effective internal control over financial reporting, we may not be able to produce accurate and timely financial statements, which may adversely affect investor confidence in us and our financial reporting, adversely affect our business and operating results and negatively impact the trading price of our common stock. As a public company, we are required to maintain effective internal control over financial reporting (as described in “Controls and Procedures” in Part I, Item 4 of this report), and effective disclosure controls and procedures. If we identify one or more material weaknesses in our internal control over financial reporting, we will not be able to assert that our internal controls and procedures are effective. A material weakness, as defined in Rule 12b-2 under the Exchange Act, is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of annual or interim financial statements will not be prevented or detected on a timely basis. In 2023, we identified and timely reported two material weaknesses in our internal control over financial reporting, which management determined to be subsequently remediated as of December 31, 2023 and September 30, 2024, respectively. Although we believe the financial statements included in this report fairly present, in all material respects, our financial condition, results of operations and cash flows for the periods presented in conformity with U.S. GAAP, any failure to maintain effective internal control over financial reporting could severely inhibit our ability to accurately report our financial condition, results of operations or cash flows. If our internal control over financial reporting is not effective, investors may lose confidence in the accuracy and completeness of our financial reports, the market price of our common stock could decline, and we could be subject to sanctions or investigations by Nasdaq, the SEC or other regulatory authorities. Future sales and issuances of securities may dilute the ownership interests of our current stockholders and cause our stock price to decline. Future sales of our common stock by us or our current stockholders into the public market could cause the market price of our stock to fall. As of June 30, 2026, there were 255,264,641 shares of our common stock outstanding. We may from time to time issue securities in relation to a license arrangement, collaboration, merger or acquisition (such as in connection with the Merger). We may also sell, for our own account, shares of common stock or other equity securities, from time to time at prices and on terms to be determined at the time of sale. As of June 30, 2026, there were 44,325,993 stock options and restricted stock units outstanding and 15,758,988 shares available for issuance under our Amended and Restated Stock Incentive Plan, 4,992,640 stock options and restricted stock units outstanding and 1,020,265 shares available for issuance under our Amended and Restated Inducement Equity Incentive Plan, and 4,474,985 shares available for issuance under our Amended and Restated Employee Stock Purchase Plan. In addition, we could also make equity grants outside of our Amended and Restated Stock Incentive Plan or Amended and Restated Inducement Equity Incentive Plan. The shares underlying existing stock options, restricted stock units and possible future stock options, stock appreciation rights, restricted stock units and stock awards have been, or will be, registered pursuant to registration statements on Form S-8. If some or all of such shares are sold or otherwise issued into the public market over a short period of time, our current stockholders’ ownership interests may be diluted and the value of all publicly traded shares is likely to decline, as the market may not be able to absorb those shares at then-current market prices. Additionally, such sales and issuances may make it more difficult for us to sell equity securities or equity-related securities in the future at a time and price that our management deems acceptable, or at all. We have anti-takeover provisions in our corporate charter documents that may result in outcomes with which you do not agree. Our Board of Directors has the authority to issue up to 5,000,000 shares of undesignated preferred stock and to determine the rights, preferences, privileges and restrictions of those shares without further vote or action by our stockholders. The rights of the holders of any preferred stock that may be issued in the future may adversely affect the rights of the holders of common stock. The issuance of preferred stock could make it more difficult for third parties to acquire a majority of our outstanding voting stock. 78 Table of Contents In addition, our Certificate of Incorporation provides for staggered terms for the members of the Board of Directors and supermajority approval of the removal of any member of the Board of Directors and prevents our stockholders from acting by written consent. Our Certificate of Incorporation also requires supermajority approval of any amendment of these provisions. These provisions and other provisions of our Amended and Restated By-Laws and of Delaware law applicable to us could delay or make more difficult a merger, tender offer or proxy contest involving us. We have never paid dividends on our common stock and do not anticipate doing so in the foreseeable future. We have never paid cash dividends on our stock. We currently intend to retain all future earnings, if any, for use in the operation of our business. Accordingly, we do not anticipate paying cash dividends on our common stock in the foreseeable future. Our Amended and Restated By-Laws provide that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for certain litigation that may be initiated by our stockholders, which may limit a stockholder’s ability to obtain a favorable judicial forum for such disputes with us or our directors, officers or employees. Our Amended and Restated By-Laws provide that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, stockholders, employees or agents to us or our stockholders, (iii) any action asserting a claim against us or any of our directors, officers, stockholders, employees or agents arising out of or relating to any provision of the General Corporation Law of Delaware or our Certificate of Incorporation or Amended and Restated By-Laws, or (iv) any action against us or any of our directors, officers, stockholders, employees or agents governed by the internal affairs doctrine of the State of Delaware. This exclusive forum provision does not apply to establish the Delaware Court of Chancery as the forum for actions or proceedings brought to enforce a duty or liability created by the Securities Act of 1933, as amended, or the Exchange Act, or any other claim for which the federal courts have exclusive jurisdiction. This exclusive forum provision may limit a stockholder’s ability to choose its preferred judicial forum for disputes with us or our directors, officers, employees or agents, which may discourage the filing of lawsuits with respect to such claims. If a court were to find this exclusive forum provision to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in another jurisdiction, which could adversely affect our business and financial condition. General Risk Factors Natural disasters, epidemic or pandemic disease outbreaks, trade wars, armed conflicts, political unrest or other events could disrupt our business or operations or those of our development partners, manufacturers, regulators or other third parties with whom we conduct business now or in the future. A wide variety of events beyond our control, such as natural disasters (including as a result of climate change), epidemic or pandemic disease outbreaks (such as the COVID-19 pandemic), trade wars, armed conflict, political unrest, government shutdowns, instability in connection with changes in the presidential administration in the United States, or other events could disrupt our business or operations or those of our development partners, manufacturers, regulatory authorities, or other third parties with whom we conduct business. These events may cause businesses and government agencies to be shut down, supply chains or trade to be interrupted, slowed, or rendered inoperable, and individuals to become ill, quarantined, or otherwise unable to work and/or travel due to health reasons or governmental restrictions. If our operations or those of third parties with whom we conduct business are impaired or curtailed as a result of these events, the development and commercialization of our products and product candidates could be impaired or halted, which could have a material adverse impact on our business. See, for example, “Risk Factors—Risks Relating to Our Business—Other Operational Risks—Our business, operations, clinical development or commercialization plans and timelines, and access to capital could be adversely affected by unpredictable and unstable market and economic conditions.” In addition, other events, such as the Ukraine-Russia and Middle East conflicts, or rising tensions between China and Taiwan, could adversely impact our business. For example, the conflicts could lead to sanctions, embargoes, supply shortages, regional instability, geopolitical shifts, cyber-attacks, other retaliatory actions, and adverse effects on macroeconomic conditions, currency exchange rates, and financial markets, which could adversely impact our operations and financial results, as well as those of third parties with whom we conduct business. We are subject to legal proceedings, which could harm our reputation or result in other losses or unexpected expenditure of time and resources. 79 Table of Contents From time to time, we may be involved in disputes, including, without limitation, disputes with our employees, collaborative partners, and third-party vendors. We may be called upon to initiate legal proceedings or to defend ourselves in such legal proceedings relating to our relationships with these parties, our decisions and actions or omissions with respect thereto, and our business. In addition, if our stock price is volatile, we may become involved in securities class action lawsuits in the future. Due to the inherent uncertainties in legal proceedings, we cannot accurately predict the ultimate outcome of any such proceeding. An unfavorable outcome in any such proceeding could have an adverse impact on our business, financial condition and results of operations. Any current or future dispute resolution or legal proceeding, regardless of the merits of any such proceeding, could harm our reputation and result in substantial costs and a diversion of management’s attention and resources that are needed to successfully run our business.
