In the second quarter of 2026, we acquired Soleno and its commercial product, VYKAT XR, which was approved by the FDA in March 2025 for the treatment of hyperphagia in adults and pediatric patients four years of age and older with PWS. The successful commercialization of VYKAT XR depends on the extent to which healthcare providers, patients and payors accept and adopt VYKAT XR, and we do not know whether our expectations or estimates in this regard, or those of investors or securities analysts, will be accurate. To generate demand for VYKAT XR, we will need to continue to educate healthcare providers on its clinical utility, benefits, risks, dosing and monitoring. Our ability to generate revenue from VYKAT XR will also depend on our ability to obtain and maintain coverage and adequate reimbursement from payors. PWS is a rare disease, and if our estimates of the prevalence of PWS, the number of patients who may benefit from treatment with VYKAT XR, the number of healthcare providers willing to prescribe VYKAT XR, or the number of patients willing to stay on treatment prove to be incorrect, the market opportunity for VYKAT XR may be smaller than we believe it is. VYKAT XR may also compete with therapeutic products in various stages of clinical development for the treatment of PWS, including hyperphagia, as well as drugs approved for other indications, such as appetite suppression. In addition, adverse events, safety concerns, product complaints or other safety-related reports regarding VYKAT XR, including serious adverse events reported after commercialization, could adversely affect market acceptance, result in regulatory scrutiny, require changes to the approved labeling for VYKAT XR, or cause patients or caregivers to discontinue use of VYKAT XR or healthcare providers to be reluctant to prescribe or continue prescribing VYKAT XR. If commercialization of VYKAT XR and future sales are less successful than anticipated by us or our investors or securities analysts, our stock price could decline and our business may be harmed.

Patient advocacy organizations and other patient communities are important across our commercial portfolio in supporting disease awareness and patient and caregiver education. These activities may be particularly significant for CRENESSITY and VYKAT XR given the rare disease nature of those indications, where education and awareness among relatively small patient and caregiver communities can affect patient identification and access to information about available treatments.

Legislators, policymakers, and payors may continue to propose and implement cost-containing measures to keep healthcare costs down. For example, in April 2025, the President issued an executive order that, among other things, directed specified agency heads to develop a Center for Medicare and Medicaid Innovation (CMMI) model that enables the Medicare program to obtain better value for high-cost prescription drugs and biological products. In May 2025, the President issued another executive order directing the administration to take immediate steps to end global freeloading and take additional aggressive action should drug manufacturers fail to offer American consumers the Most-Favored Nation (MFN) price. In December 2025, the Centers for Medicare & Medicaid Services (CMS) issued proposed regulations that, if finalized, would create CMMI demonstrations that would institute MFN-level pricing in the Medicare Part D and Part B markets. At present, given that the demonstrations are proposed rules that may or may not be finalized or implemented, there is uncertainty as to how these and other potential legal and regulatory changes may impact our business. However, if implemented, these policies could reduce or limit the prices we are able to charge for our products and product candidates that we may successfully develop and for which we may obtain regulatory approval or the level of reimbursement available for our products from governmental authorities or third-party payors. Further, in January 2026, the President released The Great Healthcare Plan, a proposal which calls on Congress to codify the administration’s MFN drug-pricing agreements with manufacturers and potentially extend MFN pricing to additional manufacturers. In addition, the One Big Beautiful Bill Act (OBBBA) is expected to reduce Medicaid spending and enrollment by implementing work requirements for some beneficiaries, capping state-directed payments, reducing federal funding and limiting provider taxes used to fund the program. The OBBBA also narrowed access to the Patient Protection and Affordable Care Act (ACA) marketplace exchange enrollment and declined to extend the ACA enhanced advanced premium tax credits, which expired at the end of 2025. These changes, along with other provisions of the OBBBA, are anticipated to reduce the number of Americans with health insurance. Further, an increasing number of countries use prices for medicinal products established in other countries as “reference prices” to help determine the price of the product in their own territory. Consequently, a downward trend in prices of medicinal products in some countries could contribute to similar downward trends elsewhere, including in the U.S.

In September 2026, CMS finalized the Global Benchmark for Efficient Drug Pricing (GLOBE) Model, a mandatory model for certain Medicare Part B drugs that will use an international pricing benchmark in calculating manufacturer rebates and is scheduled to begin in January 2027. The proposed Guarding U.S. Medicare Against Rising Drug Costs (GUARD) Model for certain Medicare Part D drugs has not been finalized.

These risks and uncertainties impact all of our clinical programs and any of the clinical, regulatory or operational events described above could change our planned clinical and regulatory activities. Geopolitical tensions could also affect our ability to obtain supplies of our investigational products, which could cause delays or otherwise disrupt our clinical trials and research and development efforts. Some of our suppliers and research and development collaborators are located in China, exposing us to the possibility of supply disruption in the event of changes to the laws, rules, regulations, and policies of the governments of the U.S. or China. Any such changes to laws or the adoption of tariffs, export controls, investment, licensing or procurement restrictions or other restrictions could impact our ability to contract with or maintain relationships with certain Chinese biotechnology companies, cause delays, or have other adverse effects on the development of certain of our research programs.

We are transforming our research and development strategies to include the development of biologics, including peptides, proteins, antibodies, conjugates, gene therapies and nucleic acid-based therapeutics. As a company, we do not have experience successfully developing and commercializing biologics and our current infrastructure may be inadequate to support the expected growth and transformation of processes, personnel, and technologies required for these new programs. We have hired employees with expertise in these modalities, but we will need to hire additional qualified personnel and expand our management, administrative, and technical staff to support the research and development organization. If we are unable to identify, recruit and integrate additional employees with the requisite skills, or effectively manage our transformation activities, the development of our biologic product candidates may not be successful, or be delayed or paused indefinitely. Gene therapies, in particular, may entail additional safety and development risks because they often require specialized administration (including intravenous administration) and may cause serious adverse events, including immune or inflammatory reactions, which could delay, suspend or terminate clinical development. Pre-existing immunity or immunity that develops after dosing may limit eligible patients and may prevent repeat dosing, which could reduce effectiveness and limit commercial adoption. Additionally, the manufacture of biologics and cognate devices are more complex than the manufacture of small molecule therapies. We currently have no manufacturing capabilities for biologic product candidates and devices and rely on third-party manufacturers. We may encounter delays in production and delivery of our biologic product candidates and devices by our third-party manufacturers or other vendors, which would result in corresponding delays to our development and commercialization of such biologic candidates. In addition, the regulatory requirements in the U.S. and in other countries governing biologics are evolving and the FDA or comparable foreign regulatory authorities may change the requirements, or identify different regulatory pathways, for approval for any of our biologic candidates. As a result, we may be required to change our regulatory strategy or to modify our applications for regulatory approval, which could delay and impair our ability to complete the preclinical and clinical development and manufacture of, and obtain regulatory approval for, our biologic candidates. We have made, and expect to continue making, substantial investments in our research and development personnel and facilities, as well in external innovation to support our expansion into the development of our biologics. If any of these risks occur and we fail to successfully develop or commercialize our biologic product candidates, we may not realize a return on our investments which could have an adverse effect …

(AEMS), formerly the FDA Adverse Event Reporting System (FAERS). Although reports in AEMS do not establish that a drug caused an adverse event and may be attributable to the patient’s underlying disease, other medications or other factors, these reports could negatively impact demand for VYKAT XR, result in regulatory scrutiny or cause patients or caregivers to discontinue use of VYKAT XR or healthcare providers to be reluctant to prescribe or continue prescribing VYKAT XR. Side effects or other safety issues associated with the use of our approved products or those of our collaborators could require us or our collaborators to modify or halt commercialization of these products or expose us to product liability lawsuits which will harm our business. We or our collaborators may be required by regulatory agencies to conduct additional studies regarding the safety and efficacy of our products which we have not planned or anticipated. Furthermore, there can be no assurance that we or our collaborators will resolve any issues related to any product related adverse events to the satisfaction of the FDA or any regulatory agency in a timely manner or ever, which could harm our business, prospects and financial condition.
Current wording
As with most pharmaceutical products, use of our approved products or those of our collaborators could be associated with side effects or adverse events which can vary in severity (from minor adverse reactions to death) and frequency (infrequent or prevalent). Side effects or adverse events associated with the use of our products or those of our collaborators may be observed at any time, including after a product is commercialized, and reports of any such side effects or adverse events may negatively impact demand for our or our collaborators’ products or affect our or our collaborators’ ability to maintain regulatory approval for such products. With respect to VYKAT XR, since it became commercially available, serious adverse events in patients taking VYKAT XR have been reported to FDA through the FDA Adverse Event Monitoring System (AEMS), formerly the FDA Adverse Event Reporting System (FAERS). In its quarterly report published in September 2026 of newly identified safety signals, the FDA identified fluid retention as a potential safety signal for VYKAT XR and stated that it is evaluating the need for regulatory action. Although reports in AEMS and the FDA's identification of a potential safety signal do not establish that a drug caused an adverse event and such events may be attributable to the patient’s underlying disease, other medications or other factors, these reports and the FDA's evaluation of the potential safety signal could negatively impact demand for VYKAT XR, result in additional regulatory scrutiny or cause patients or caregivers to discontinue use of VYKAT XR or healthcare providers to be reluctant to prescribe or continue prescribing VYKAT XR. Side effects or other safety issues associated with the use of our approved products or those of our collaborators could result in changes to product labeling or requirements to implement risk mitigation measures, require us or our collaborators to modify or halt commercialization of these products or expose us to product liability lawsuits which will harm our business. We or our collaborators may be required by regulatory agencies to conduct additional studies regarding the safety and efficacy of our products which we have not planned or anticipated. Furthermore, there can be no assurance that we or our collaborators will resolve any issues related to any product related adverse events to the satisfaction of the FDA or any regulatory agency in a timely manner or ever, which could harm our business, prospects and financial condition.

The market prices for securities of biotechnology and pharmaceutical companies historically have been highly volatile, and the market for these securities has from time to time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. For example, the applicability of the Medicare drug price negotiation provisions in the IRA negatively affected investor sentiment and resulted in significant volatility. Furthermore, especially as we and our market capitalization have grown, the price of our common stock has been increasingly affected by quarterly and annual comparisons with the valuations and recommendations of the analysts who cover our business. If our results do not meet these analysts’ forecasts, the expectations of our investors or the financial guidance we provide to investors in any period, which is based on assumptions that may be incorrect or that may change from quarter to quarter, the market price of our common stock could decline. Over the course of the last 12 months, the price of our common stock has ranged from approximately $122 per share to approximately $181 per share.

In October 2024, our Board of Directors authorized a share repurchase program to repurchase up to $300 million of our common stock and we subsequently entered into an accelerated share repurchase (ASR) transaction to repurchase the entirety of this authorized amount. The purchase period for this ASR transaction ended in February 2025 and an aggregate of 2.3 million shares were delivered to us at an average repurchase price of $131.83 per share. Additionally, in February 2025, our Board of Directors authorized a share repurchase program under which we may repurchase up to $500 million of our common stock (of which $266.3 million remained available for additional repurchases as of June 30, 2026). This subsequent share repurchase authorization was in addition to the $300 million accelerated share repurchase program that was announced in October 2024 and completed in early February 2025. Our share repurchases may change from time to time, and we can provide no assurance that we will repurchase shares of our common stock at favorable prices, in particular amounts, or at all, and any repurchases may not enhance long-term stockholder value or prove to be the best use of our cash. If our Board of Directors authorizes any additional share repurchase programs, it could affect the trading price of our stock and increase volatility.

Any sales of our product once commercialized outside the U.S. will also likely subject us to foreign equivalents of the healthcare laws mentioned above, among other foreign laws. Additionally, because of our U.S. and international operations, we are also subject to anti-corruption laws and regulations, in the U.S. and internationally, including but not limited to the U.S. Foreign Corrupt Practices (FCPA), the U.K. Bribery Act 2010, and other applicable anti-bribery and corruption laws. Anti-corruption laws are interpreted broadly and prohibit corporations and individuals from engaging in certain activities to obtain or retain business or to influence a person working in an official capacity. It is illegal to pay, offer to pay or authorize the payment of anything of value to any foreign government official, government staff member, political party, or political candidate in an attempt to obtain or retain business or to otherwise influence a person working in an official capacity. The FCPA also imposes accounting standards and requirements on publicly traded U.S. corporations and their foreign affiliates, which are intended to prevent the diversion of corporate funds to the payment of bribes and other improper payments. Recent years have seen substantial increase in the global enforcement of anti-corruption laws. Our operations outside the U.S. could increase the risk of such violations. Our business is also heavily regulated and involves significant interaction with foreign officials. In many countries outside the U.S., independent clinical investigators conducting our clinical trials and prescribers of our products are employed by government entities, and purchasers themselves can be government entities. As such, our interactions with such investigators, prescribers and purchasers may be subject to regulation under the FCPA, as well as other similar under anti-corruption laws and/or regulations enacted by other countries. Failure to comply with these laws, where applicable, can result in significant penalties, including the imposition of significant civil, criminal and administrative penalties, damages, monetary fines, disgorgement, imprisonment, possible exclusion from participation in Medicare, Medicaid and other federal and equivalent foreign healthcare programs, and additional reporting requirements and regulatory oversight, any of which could adversely affect our ability to operate our business and our results of operations.

We source and procure APIs, precursor chemicals, and specialized equipment from international suppliers, with substantial reliance on foreign contract manufacturers in Europe. Tariff policies, particularly those affecting pharmaceutical products, could increase our costs and reduce our profitability. Additionally, recent policy discussions have included potential targeted tariffs or other trade measures specifically aimed at pharmaceutical products and ingredients as part of broader healthcare cost control or national security initiatives. In April 2025, the U.S. Department of Commerce initiated an investigation on imports of pharmaceuticals and pharmaceutical ingredients, which may result in the current U.S. presidential administration taking actions to impose tariffs on the pharmaceutical industry. The U.S. presidential administration also indicated that it may impose a 100% tariff on any branded or patented pharmaceutical product, unless a company is building a pharmaceutical manufacturing plant in the U.S. The specific impact of the investigation and announcements to enact substantial tariffs on patented pharmaceutical products remain uncertain at this time but could negatively impact our business and operations. Unlike consumer goods, pharmaceuticals face unique regulatory constraints that make rapid supply chain adjustments particularly difficult and costly. Should tariffs be imposed specifically targeting pharmaceutical imports, our production costs could rise, and it would be difficult and costly to qualify alternative sources within another country with a lower tariff rate or within the U.S., as developing and qualifying alternative sources typically requires substantial time, investment, and regulatory approvals.

Tariff policies, particularly those affecting pharmaceutical products, could increase our costs and reduce our profitability. The U.S. presidential administration has imposed tariffs on imports of certain patented pharmaceutical products and associated ingredients, subject to varying rates and exemptions. Although these tariffs have not had a material impact on our business, financial condition or results of operations to date, the imposition of new tariffs or changes to existing tariff rates or exemptions could negatively affect our business and operations.

Current or future tariffs will also result in increased research and development expenses, including with respect to increased costs associated with APIs, raw materials, laboratory equipment and research materials and components. Trade restrictions affecting the import of materials necessary for clinical trials could result in delays to our development timelines. Increased development costs and extended development timelines could place us at a competitive disadvantage compared to companies operating in regions with more favorable trade relationships and could reduce investor confidence and negatively impact our business, results of operations, financial condition and growth prospects.

Increased development costs and extended development timelines could place us at a competitive disadvantage compared to companies operating in regions with more favorable trade relationships and could reduce investor confidence and negatively impact our business, results of operations, financial condition and growth prospects.
Previous wording
Cyber-attacks, malicious internet-based activity, online and offline fraud, and other similar activities threaten the confidentiality, integrity, and availability of our sensitive information and information technology systems, and those of the third parties with whom we work. Such threats continue to rise, are increasingly difficult to detect, and come from a variety of sources, including traditional computer “hackers,” threat actors, “hacktivists,” organized criminal threat actors, personnel (such as through theft or misuse), sophisticated nation states, and nation-state-supported actors (also referred to as APTs). Some actors now engage and are expected to continue to engage in cyber-attacks, including without limitation nation-state actors for geopolitical reasons and in conjunction with military conflicts and defense activities. During times of war and other major conflicts, we and the third parties with whom we work are vulnerable to a heightened risk of these attacks, including retaliatory cyber-attacks, which could materially disrupt our systems and operations, as well as our ability to conduct clinical trials.

Our business could be adversely affected by conditions in the U.S. and global economies, the U.S. and global financial markets and adverse geopolitical and macroeconomic developments, including potential future disruptions in access to bank deposits due to bank failures, tariffs and trade barriers, government shutdowns and the resulting effects on regulatory agencies, geopolitical tensions, and military conflicts. General business and economic conditions that could affect our business, financial condition or results of operations include fluctuations in economic growth, inflation and interest rates, debt and equity capital markets, liquidity of the global financial markets, the availability and cost of credit, investor and consumer confidence, and the strength of the economies in which we, our manufacturers and suppliers, and our collaborators operate. A weak or declining global economy due to geopolitical tensions or tariffs and trade barriers could also strain our suppliers and manufacturers, possibly resulting in supply disruption. Any of the foregoing could harm our business and we cannot anticipate all of the ways in which the current economic climate and financial market conditions could adversely impact our business.

Switzerland. The GDPR provides for enhanced data protection obligations for processors and controllers of personal data, including, for example, obligations relating to: processing health and other sensitive data; obtaining consent of individuals; providing notice to individuals regarding data processing activities; responding to data subject requests; taking certain measures when engaging third-party processors; notifying data subjects and regulators of data breaches; and implementing safeguards to protect the security and confidentiality of personal data. The GDPR imposes substantial fines for breaches of data protection requirements. For example, under the GDPR, such fines can be up to four percent of global revenue or 20 million euros under the EU GDPR / 17.5 million pounds sterling under the UK GDPR, whichever is greater in either case, and also allow for private litigation related to processing of personal data brought by classes of data subjects or consumer protection organizations authorized at law to represent their interests. The GDPR and other changes in laws or regulations associated with the enhanced protection of certain types of sensitive data, such as EU regulations governing clinical trial data and other healthcare data, could require us to change our business practices or lead to government enforcement actions, private litigation or significant penalties against us and could have a material adverse effect on our business, financial condition or results of operations.
Current wording
Laws in Europe regarding privacy, data protection, information security and the processing of personal data have also been significantly reformed and continue to undergo reform. For example, the EU’s General Data Protection Regulation (EU GDPR) and the UK’s GDPR (UK GDPR) (collectively, GDPR) impose strict requirements for processing the personal data of individuals located, respectively, within the European Economic Area (EEA) and the UK, and the Swiss Federal Act on Data Protection similarly applies to the collection and processing of personal data, including health-related information, in Switzerland.

In addition, adverse events, safety concerns, product complaints or other safety-related reports regarding VYKAT XR, including serious adverse events reported after commercialization, could adversely affect market acceptance, result in regulatory scrutiny, require changes to the approved labeling for VYKAT XR, or cause patients or caregivers to discontinue use of VYKAT XR or healthcare providers to be reluctant to prescribe or continue prescribing VYKAT XR. For example, in August 2026, certain PWS patient advocacy organizations issued a statement regarding serious adverse events reported through the FDA's Adverse Event Reporting System (AEMS) in patients taking VYKAT XR and encouraged increased awareness of risks and monitoring considerations when initiating treatment. Although the statement noted that the adverse event reports do not establish whether VYKAT XR caused the reported events, the statement and related publicity could adversely affect perceptions of the safety of VYKAT XR, influence treatment decisions or otherwise reduce demand for VYKAT XR. If commercialization of VYKAT XR and future sales are less successful than anticipated by us or our investors or securities analysts, our stock price could decline and our business may be harmed.

As with most pharmaceutical products, use of our approved products or those of our collaborators could be associated with side effects or adverse events which can vary in severity (from minor adverse reactions to death) and frequency (infrequent or prevalent). Side effects or adverse events associated with the use of our products or those of our collaborators may be observed at any time, including after a product is commercialized, and reports of any such side effects or adverse events may negatively impact demand for our or our collaborators’ products or affect our or our collaborators’ ability to maintain regulatory approval for such products. With respect to VYKAT XR, since it became commercially available, serious adverse events in patients taking VYKAT XR have been reported to FDA through the FDA Adverse Event Reporting System
