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 our drug discovery and 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.

Previous wording

The success of the Merger will depend, in part, on the ability to realize the anticipated benefits, and cost savings from combining our business and Astria’s business. To realize the anticipated benefits and synergies from the Merger, we must successfully integrate and combine our businesses in a manner that permits those benefits and synergies to be realized. If we are not able to successfully achieve these objectives, the anticipated benefits of the Merger may not be realized fully or at all or may take longer to realize than expected. In addition, the actual cost savings and anticipated benefits of the Merger could be less than anticipated, and integration may result in additional unforeseen expenses. There can be no assurance that the anticipated benefits related to the integration of Astria with our business will be realized to offset the transaction and integration expenses over time.

Current wording

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.

Previous wording

The market price of our common stock may decline as a result of the Merger if we do not achieve the perceived benefits of the Merger as rapidly or to the extent anticipated by financial analysts or investors or if the effect of the Merger on our financial results is not consistent with the expectations of financial analysts or investors. Accordingly, holders of our common stock following the consummation of the Merger may experience a loss as a result of a decline in the market price of such common stock. In addition, former Astria stockholders or holders of other Astria securities may decide not to hold the shares of our common stock that they have received in connection with the Merger, and our stockholders may decide to reduce their investment in us as a result of the changes to our investment profile as a result of 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 if needed and to obtain additional financing in the future.

Current wording

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.

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 our internal identification and discovery of product candidates or otherwise 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. 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 or integrate viable products or product candidates into our business on acceptable terms, or at all, our business and product development efforts could suffer.

Current wording

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.

Previous wording

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 trial do not necessarily predict final results. For example, any successful results of preclinical and early clinical work for navenibart, BCX17725, and our early-stage discovery programs do not guarantee the success of later clinical trials. 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.

Undesirable or inconclusive data in our 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.

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 market research, 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.

Once an 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.

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 BPCIA was included in the 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 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.

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, we recently identified a manufacturing issue affecting our oral pellet formulation of ORLADEYO that will delay initial product fulfillment and could negatively impact our future revenue and financial results.

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.

Previous wording

We have experienced significant growth in the number of our employees and the scope of our operations. To manage our growth, we must continue to implement and improve our managerial, operational and financial systems and processes, and continue to recruit and train qualified personnel as needed. Due to our limited financial resources and the limited experience of our management team in managing a company with such growth, we may not be able to effectively manage such expansion of our operations, implement appropriate systems and processes in a timely manner or at all, or recruit, train, and retain qualified personnel. The expansion of our operations may lead to significant costs and may divert our management and business development resources. In addition, if a commercial launch for any product or product candidate for which we recruit a commercial team and establish 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 growth could delay the execution of our business plans or disrupt our operations.

Current wording

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.

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 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.

Our third-party manufacturers also may not meet our manufacturing requirements. 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 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.

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 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. Most 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, most 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:

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 several 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.

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.

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 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.

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 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.

Current wording

We use AI in our business, and challenges with properly managing its use could adversely affect our business.

Previous wording

The increasing use of AI and machine learning technology in the biopharmaceutical industry, combined with an uncertain regulatory environment, presents new risks and challenges. From time to time, we adopt and integrate AI solutions into our ecosystem for specific use cases reviewed by legal and information security, and applications of AI may become 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.

We anticipate that 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.
