Below we are providing, in supplemental form, changes to our risk factors from those previously disclosed in Part I, Item 1Aof our Annual Report on Form 10-K for the year ended December 31, 2024. Our risk factors disclosed in Part I, Item 1Aof our Annual Report on Form 10-K for the year ended December 31, 2024, provide additional discussion regarding these supplemental risks and we encourage you to read and carefully consider all of the risk factors disclosed in Part I, Item 1Aof our Annual Report on Form 10-K for the year ended December 31, 2024, together with the below, for a more complete understanding of the risks and uncertainties material to our business.

The pricing of pharmaceutical products has come under increasing scrutiny as part of a global trend toward healthcare cost containment and resulting changes in healthcare law and policy, including changes to Medicare, may impact our business in ways that we cannot currently predict, which could have a material adverse effect on our business and financial condition.

Political, economic and regulatory influences are subjecting the healthcare industry in the U.S. to fundamental changes, particularly given the current atmosphere of mounting criticism of prescription drug costs in the U.S. We expect there will continue to be legislative and regulatory proposals to change the healthcare system in ways that could impact our ability to sell our products profitably, as governmental oversight and scrutiny of biopharmaceutical companies is increasing. For example, we anticipate that the U.S. Congress, state legislatures, and federal and state regulators may adopt or accelerate adoption of new healthcare policies and reforms intended to curb healthcare costs, such as federal and state controls on reimbursement for drugs (including under Medicare, Medicaid and commercial health plans), new or increased requirements to pay prescription drug rebates and penalties to government health care programs, and additional pharmaceutical cost transparency policies that aim to require drug companies to justify their prices through required disclosures. This includes efforts by individual states in the U.S. to pass legislation and implement regulations designed to control pharmaceutical and biological product pricing, including by establishing Prescription Drug Affordability Boards (or similar entities) to review high-cost drugs and, in some cases, set upper payment limits and implementing marketing cost disclosure and transparency measures. Further, the IRA, among other things, requires the U.S. Department of Health and Human Services Secretary to negotiate, with respect to Medicare units and subject to a specified cap, the price of a set number of certain high Medicare spend drugs and biologicals per year starting in 2026, penalizes manufacturers of certain Medicare Parts B and D drugs for price increases above inflation, and makes several changes to the Medicare Part D benefit, including a limit on annual out-of-pocket costs and a change in manufacturer liability under the program, which could negatively affect our business and financial condition. CMS has issued final guidance implementing the Drug Price Negotiation Program in which it finalized certain policies governing the selection of drugs for negotiation. Among other things, CMS finalized definitions of “qualifying single source drug” and “marketed” that, especially if they persist, could further disincentivize innovation. On April 15, 2025, the current administration issued an executive order directing HHS to make changes to the Drug Price Negotiation Program. In addition, under the Medicaid Drug Rebate Program, rebates owed by manufacturers are no longer subject to a cap on the rebate amount effective January 1, 2024, which may adversely affect our rebate liability. The foregoing may effectively reduce the prices at which our products are sold, which would have a negative adverse effect on our revenues.

Legislative and regulatory proposals that have recently been considered include, among other things, proposals to limit the terms of patent litigation settlements with generic sponsors, to define certain conduct around patenting and new product development as unfair competition, to address the scope of orphan drug exclusivity and to facilitate the importation of drugs into the U.S. from other countries. Legislative and regulatory proposals to reform the regulation of the pharmaceutical industry and reimbursement for pharmaceutical drugs are continually changing, and all such considerations may adversely affect our business and industry in ways that we cannot accurately predict.

There is also ongoing activity related to health care coverage. The Affordable Care Act substantially changed the way healthcare is financed by both governmental and private insurers. These changes impacted previously existing government healthcare programs and have resulted in the development of new programs, including Medicare payment-for-performance initiatives. Further, federal and state policy makers have taken and may continue to try to take steps regarding health care coverage beyond the Affordable Care Act, which could have ramifications for the pharmaceutical industry. Additional legislative changes, regulatory changes, or guidance could be adopted, which may impact the marketing approvals and reimbursement for our products and product candidates. For example, there has been increasing legislative, regulatory, and enforcement interest in the U.S. with respect to drug pricing practices. There have been several Congressional inquiries and proposed and enacted federal and state legislation and regulatory initiatives designed to, among other things, bring more transparency to product pricing, evaluate the relationship between pricing and manufacturer patient programs, and reform government healthcare program reimbursement methodologies for drug products beyond the changes enacted by the IRA.

If new healthcare policies or reforms intended to curb healthcare costs are adopted or if we experience negative publicity with respect to pricing of our products or the pricing of pharmaceutical drugs generally, the prices that we charge for our products may be affected, our commercial opportunity may be limited and/or our revenues from sales of our products may be negatively impacted. We have periodically increased the price of our products, including Xywav and Xyrem most recently in January 2025, and there is no guarantee that we will not make similar price adjustments to our products in the future or that price adjustments we have taken or may take in the future will not negatively affect our sales volumes and revenues. There is no guarantee that such price adjustments will not negatively affect our reputation and our ability to secure and maintain reimbursement coverage for our products, which could limit the prices that we charge for our products, limit the commercial opportunities for our products and/or negatively impact revenues from sales of our products.

Government investigations or U.S. Congressional oversight with respect to drug pricing or our other business practices could cause us to incur significant expense and could distract us from the operation of our business and execution of our strategy. Any such investigation or hearing could also result in reduced market acceptance and demand for our products, could harm our reputation and our ability to market our products in the future, and could have a material adverse effect on our business, financial condition, results of operations and growth prospects. For more information, see the risk factor under the heading “We are subject to significant ongoing regulatory obligations and oversight, which may subject us to civil or criminal proceedings, investigations, or penalties and may result in significant additional expense and limit our ability to commercialize our products” in Part I, Item 1A of our Annual Report on Form 10-K for year ended December 31, 2024.

We expect that legislators, policymakers and healthcare insurance funds in Europe and other international markets will continue to propose and implement cost-containing measures to keep healthcare costs down. These measures could include limitations on the prices we will be able to charge for our products or the level of reimbursement available for these products from governmental authorities or third party payors as well as clawbacks and revenue caps. For example, in the U.K., the cap on NHS spending on branded medicines agreed between the U.K. government and industry for 2019 to 2023 has remained unaltered despite higher than expected growth in NHS use of branded medicines, resulting in significant increases to the industry level revenue clawback rate payable on sales of branded medicines to the NHS. In the EU, a trend in some EU member states is for medicinal products to be reimbursed based on the relative price of competitor products, which may undervalue newer innovative products. On April 26, 2023, the EC adopted proposals for a new Directive and a new Regulation, which revise and replace the existing EU general pharmaceutical legislation. This proposal includes increased transparency on research and development costs or public contributions to these costs with a view to strengthen the negotiating position of national competent authorities of the EU member states responsible for pricing and reimbursement, as well as reinforced cooperation with these authorities on pricing and reimbursement matters. On April 10, 2024, the European Parliament adopted its position on the proposals, whose legislative processes are expected to continue in 2025. Further, an increasing number of European and other foreign 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.

Global trade issues and changes in and uncertainties with respect to trade policies and export regulations, including import and export license requirements, trade sanctions, tariffs and international trade disputes, could increase our costs, reduce the competitiveness of our products and otherwise have a material adverse effect on our business, financial condition, results of operations and growth prospects.

There is inherent risk, based on the complex relationships among the U.S. and the countries in which we conduct our business, that political, diplomatic, and national security factors can lead to global trade restrictions and changes in trade policies and export regulations that may adversely affect our business and operations. Compliance with applicable regulatory requirements regarding the export of our products may create delays in the introduction of our products in international markets or, in some cases, prevent the export of our products to some countries altogether. Furthermore, U.S. export control laws and economic sanctions prohibit the provision of certain products and services to countries, governments and persons targeted by U.S. sanctions. The U.S. and other countries have imposed and may continue to impose new trade restrictions and export regulations, have levied tariffs and taxes on certain goods, and could continue to significantly increase tariffs on a broad array of goods, including pharmaceutical and biological products.

While we are an Irish company headquartered in Dublin, Ireland, we derive the majority of our revenues from sales of our products in the U.S. We conduct business globally and our operations, including third-party suppliers, span numerous countries outside the U.S. In particular, we have a manufacturing and development facility in Athlone, Ireland where we manufacture Xywav and Xyrem, a manufacturing and development facility in Kent Science Park, U.K. where we produce

Epidiolex/Epidyolex, and a manufacturing plant in Villa Guardia, Italy where we produce defibrotide drug substance. In addition, we rely on our supplier in China for the manufacture of Ziihera.

In 2025, President Trump signed a series of executive orders imposing various reciprocal tariffs. Most pharmaceutical products are currently exempt from the reciprocal tariffs. However, at President Trump's request, the U.S. Secretary of Commerce has initiated a Section 232 investigation that is expected to result in new tariffs on pharmaceutical products. Such tariffs will result in additional costs on our business, including costs with respect to APIs and other raw materials upon which our business depends and will generally increase our manufacturing costs. In addition, such tariffs will increase our supply chain complexity and could also potentially disrupt our existing supply chain. Moreover, other governments have imposed and may continue to impose retaliatory tariffs, trade restrictions or trade barriers on our products, which may impose additional costs and complexity on our business.

While we cannot at this time predict the ultimate impact of such tariffs, we anticipate that that our margins could be adversely affected beginning as early as fiscal 2026, depending on the ultimate scope and duration of tariffs imposed. Additionally, it is possible that such tariffs could affect imports of APIs and other raw materials used in our products, or our business may be adversely impacted by retaliatory trade measures taken by other countries, including restricted access to APIs or other raw materials used in our products, further disrupting our supply chain and increasing our costs. Given the nature of our products, relocating the manufacturing supply in response to tariffs and other trade restrictions would be a complex, costly and time-consuming process making it difficult for us to react quickly to a rapidly changing environment. In this regard, it would take a significant amount of time and expense to implement and execute the necessary technology transfer to, and to qualify, new suppliers for our products. If there are delays in qualifying new suppliers or facilities or a new supplier is unable to meet FDA’s or similar international regulatory body’s requirements for approval, there could be a shortage of the affected products for the marketplace or for use in clinical studies, or both, which could negatively impact our anticipated revenues.

Further, the continued threats of new or increased tariffs, sanctions, trade restrictions and trade barriers as well as ongoing changes in U.S. and foreign government trade policies, including potential modifications to existing trade agreements, have had and may continue to have a generally disruptive impact on the global economy and, therefore, negatively impact revenues from sales of our products. Given the volatility and uncertainty regarding the scope and duration of such tariffs and other aspects of U.S. and foreign government trade policies, the ultimate impact on our operations and financial results is uncertain and could be significant. In any event, further trade restrictions and export regulations, or new or increased tariffs, including further retaliatory measures, could increase our supply chain complexity and our manufacturing costs, decrease our margins, reduce the competitiveness of our products, or restrict our ability to sell our products, provide services or purchase necessary equipment and supplies. Any of these factors could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

We may not realize the anticipated benefits from our acquisition of Chimerix.

On April 21, 2025, we completed the acquisition of all the outstanding shares of Chimerix Common Stock. As a result of this, Chimerix became an indirect wholly owned subsidiary of the Company. The success of the acquisition will depend, in part, on our ability to realize the anticipated benefits from successfully combining our and Chimerix’s operations and we plan on devoting management attention and resources to integrating our business practices and operations with Chimerix’s so that we can fully realize the anticipated benefits of the acquisition. In addition, Chimerix’s NDA for dordaviprone seeking accelerated approval for treatment of H3 K27M-mutant diffuse glioma in adult and pediatric patients with progressive disease following prior therapy may not be approved by FDA in a timely manner or at all. Moreover, dordaviprone, if approved, may not be successful or they may require significantly greater resources and investments than originally anticipated. The transaction could also result in the assumption of unknown or contingent liabilities. In addition, difficulties may arise during the process of combining the operations of our companies that could result in the failure to achieve revenue that we anticipate, the loss of key employees that may be difficult to replace in the very competitive pharmaceutical field, the failure to harmonize both companies’ corporate cultures, the disruption of each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies that adversely affect our ability to maintain relationships with suppliers, collaboration partners, clinical trial investigators or managers of our clinical trials. As a result, the anticipated benefits of the acquisition may not be realized fully within the expected timeframe or at all or may take longer to realize or cost more than expected, which could materially and adversely affect our business, financial condition, results of operations and growth prospects.

We may not be able to successfully identify and acquire or in-license additional products or product candidates to grow our business, and, even if we are able to do so, we may otherwise fail to realize the anticipated benefits of these transactions.

In addition to continued investment in our research and development pipeline, we intend to grow our business by acquiring or in-licensing, and developing, including with collaboration partners, additional products and product candidates that we believe are highly differentiated and have significant commercial potential. However, we may be unable to identify or consummate suitable acquisition or in-licensing opportunities, andthis inability could impair our ability to grow our business. Other companies, many of which may have substantially greater financial, sales and marketing resources, compete with us for these opportunities. Even if appropriate opportunities are available, we may not be able to successfully identify them, or we may not have the financial resources necessary to pursue them.

Even if we are able to successfully identify and acquire, in-license or develop additional products or product candidates, we may not be able to successfully manage the risks associated with integrating any products or product candidates into our portfolio or the risks arising from anticipated and unanticipated problems in connection with an acquisition or in-licensing or from financial difficulties of our collaborators. Further, while we seek to mitigate risks and liabilities of potential acquisitions and in-licensing transactions through, among other things, due diligence, there may be risks and liabilities that such due diligence efforts fail to discover, that are not disclosed to us, or that we inadequately assess. Any failure in identifying and managing these risks, liabilities and uncertainties effectively, could have a material adverse effect on our business, results of operations and financial condition. In addition, product and product candidate acquisitions, particularly when the acquisition takes the form of a merger or other business consolidation, such as our acquisition of GW have required, and any similar future transactions also will require, significant efforts and expenditures, including with respect to transition and integration activities. We may encounter unexpected difficulties, or incur substantial costs, in connection with potential acquisitions and similar transactions, which include:

•the need to incur substantial debt and/or engage in dilutive issuances of equity securities to pay for acquisitions;

•the need to comply with regulatory requirements, including in some cases clearance from the FTC;

•the potential need to secure shareholder approval of the transaction;

•the potential disruption of our historical core business;

•the strain on, and need to continue to expand, our existing operational, technical, financial and administrative infrastructure;

•the difficulties in integrating acquired products and product candidates into our portfolio;

•the difficulties in assimilating employees and corporate cultures;

•the failure to retain key managers and other personnel;

•the need to write down assets or recognize impairment charges;

•the diversion of our management’s attention to integration of operations and corporate and administrative infrastructures; and

•any unanticipated liabilities for activities of or related to the acquired business or its operations, products or product candidates.

As a result of these or other factors, products or product candidates we acquire, or obtain licenses to, may not produce the revenues, earnings or business synergies that we anticipated, may not result in regulatory approvals, and may not perform as expected. For example, in May 2021, we made a substantial investment in Epidiolex and certain other products and technologies acquired in our acquisition of GW. The total consideration paid by us for the entire issued share capital of GW was $7.2 billion. Additionally, in April 2025, we completed our acquisition of Chimerix, a biopharmaceutical company the lead clinical asset of which is dordaviprone, a novel first-in-class small molecule treatment in development for H3 K27M-mutant diffuse glioma, a rare, high-grade brain tumor that most commonly affects children and young adults. The total consideration paid by us for the outstanding shares of Chimerix Common Stock was approximately $935 million. The success of our acquisition of GW and Chimerix will depend, in part, on our ability to realize the anticipated benefits from each of the acquisitions, which benefits may not be realized at the expected levels within the expected timeframe, or at all, or may take longer to realize or cost more than expected, which could materially and adversely affect our business, financial condition, results of operations and growth prospects. In this regard, in the third quarter of 2022, we recorded a $133.6 million asset impairment charge as a result of the decision to discontinue the nabiximols program that we acquired as part of our acquisition of GW. In any event, failure to manage effectively our growth through acquisitions or in-licensing transactions could adversely affect our growth prospects, business, results of operations and financial condition.

It is difficult and costly to protect our proprietary rights, and we may not be able to ensure their protection.

Our commercial success depends in part on obtaining, maintaining and defending intellectual property protection for our products and product candidates, including protection of their use and methods of manufacturing. Our ability to protect our products and product candidates from unauthorized making, using, selling, offering to sell or importation by third parties depends on the extent to which we have rights under valid and enforceable patents or have adequately protected trade secrets that cover these activities.

The degree of protection to be afforded by our proprietary rights is difficult to predict because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage. For example:

•our patent applications, or those of our licensors or partners, may not result in issued patents;

•others may independently develop similar or therapeutically equivalent products without infringing our patents, or those of our licensors, such as products that are not covered by the claims of our patents, or for which fall outside the exclusive rights granted under our license agreements;

•our issued patents, or those of our licensors or partners, may be held invalid or unenforceable as a result of legal challenges by third parties or may be vulnerable to legal challenges as a result of changes in applicable law;

•our patents covering certain aspects of our products or the use thereof could be delisted from FDA's Orange Book as a result of challenges by third parties before FDA or the courts;

•competitors may manufacture products in countries where we have not applied for patent protection or that have a different scope of patent protection or that do not respect our patents; or

•others may be issued patents that prevent the sale of our products or require licensing and the payment of significant fees or royalties.

Patent enforcement generally must be sought on a country-by-country basis, and patent validity and infringement may be judged differently in different countries. The legal systems of certain countries, particularly certain developing countries, may lack maturity or consistency when it comes to the enforcement of patents and other intellectual property rights, particularly those relating to pharmaceuticals, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights generally. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business.

Changes in either the patent laws or in interpretations of patent laws in the U.S. and other countries may diminish the value of our intellectual property portfolio. Any patent may be challenged, and potentially invalidated or held unenforceable, including through patent litigation or through administrative procedures that permit challenges to patent validity. Patents can also be designed around by an ANDA or Section 505(b)(2) NDA that avoids infringement of our intellectual property.

In June 2021, we received notice from Lupin that it has filed with FDA an ANDA for a generic version of Xywav. The notice from Lupin included a “paragraph IV certification” with respect to ten of our patents listed in FDA’s Orange Book for Xywav on the date of our receipt of the notice. A paragraph IV certification is a certification by a generic applicant that patents covering the branded product are invalid, unenforceable, and/or will not be infringed by the manufacture, use or sale of the generic product. In April 2022, we received notice from Lupin that it had filed a paragraph IV certification regarding a newly-issued patent listed in the Orange Book for Xywav. In February 2023, we received notice from Teva that it had filed an ANDA seeking approval to market a generic version of Xywav, which notice included a paragraph IV certification with respect to certain of our patents listed in FDA’s Orange Book for Xywav. For additional information on litigation involving these matters, see Note 9, Commitments and Contingencies—Legal Proceedings of the Notes to Consolidated Financial Statements, included in Part I of this Quarterly Report on Form 10-Q.

We have settled patent litigation with each of the ten companies seeking to introduce generic versions of Xyrem in the U.S. by granting those companies licenses to launch their generic products (and in certain cases, an AG version of Xyrem) in advance of the expiration of the last of our patents. Notwithstanding our Xyrem patents and settlement agreements, additional third parties may also attempt to introduce generic versions of Xyrem, Xywav or other sodium oxybate products for treatment of cataplexy and/or EDS in narcolepsy that design around our patents or assert that our patents are invalid or otherwise unenforceable. Such third parties could launch a generic or 505(b)(2) product referencing Xyrem before the dates provided in our patents or settlement agreements. For example, we have several methods of use patents listed in the Orange Book, that expire in 2033 that cover treatment methods included in the Xyrem label related to a DDI with divalproex sodium. Although FDA has stated, in granting a Citizen Petition we submitted in 2016, that it would not approve any sodium oxybate ANDA referencing Xyrem that does not include the portions of the currently approved Xyrem label related to the DDI patents, we cannot predict whether a future ANDA filer, or a company that files a Section 505(b)(2) application for a drug referencing Xyrem, may pursue regulatory strategies to avoid infringing our DDI patents notwithstanding FDA’s response to the Citizen Petition, or whether any such strategy would be successful. Likewise, we cannot predict whether we will be able to maintain the validity of these patents or will otherwise obtain a judicial determination that a generic or other sodium oxybate product, its package insert or the generic sodium oxybate REMS or another separate REMS will infringe any of our patents or, if we prevail in proving infringement, whether a court will grant an injunction that prevents a future ANDA filer or other company introducing a different sodium oxybate product from marketing its product, or instead require that party to pay damages in the form of lost profits or a reasonable royalty.

Since Xyrem’s regulatory exclusivity has expired in the EU, we are aware that generic or hybrid generic applications have been approved by various EU regulatory authorities, and additional generic or hybrid generic applications may be submitted and approved.

We have settled patent litigation with each of the ten companies seeking to market a generic version of Epidiolex in the U.S. by granting each of the Epidiolex ANDA Filers a license to manufacture, market, and sell its own generic version of Epidiolex beginning in the very late 2030s, or earlier under certain circumstances, including but not limited to the launch of another generic Epidiolex product or a final decision that all unexpired claims of the Epidiolex patents are not infringed, or are invalid and/or unenforceable. Notwithstanding our patents listed in FDA’s Orange Book for Epidiolex and settlement agreements, additional third parties may also attempt to introduce generic versions of Epidiolex that design around our patents or assert that our patents are invalid or otherwise unenforceable.

In March 2025, we received a notice from Almaject that it had filed with FDA an ANDA for a generic version of Defitelio (defibrotide sodium). The notice from Almaject included a paragraph IV certification respect to certain of our patents listed in FDA’s Orange Book for Defitelio on the date of the notice. The listed patents relate generally to the Defitelio drug product and its approved use. For additional information on litigation involving this matter, see Note 9, Commitments and Contingencies—Legal Proceedings of the Notes to Consolidated Financial Statements, included in Part I of this Quarterly Report on Form 10-Q.

On May 13, 2021, we filed a patent infringement suit against Avadel and several of its corporate affiliates in the United States District Court for the District of Delaware. The suit alleges that Avadel’s product candidate FT218 will infringe five of our patents related to controlled release formulations of oxybate and the safe and effective distribution of oxybate. In March 2024, the jury upheld the validity of both of our asserted patents and awarded us damages for infringement for past sales of Lumryz in the U.S. For additional information on litigation involving this matter, see “Avadel Litigation” in Note 9, Commitments and Contingencies—Legal Proceedings of the Notes to Consolidated Financial Statements, included in Part I of this Quarterly Report on Form 10‑Q.

In July and August 2024, Zepzelca ANDA filers sent us notices that they had filed ANDAs seeking approval to market a generic version of Zepzelca (lurbinectedin), which notices each included a paragraph IV certification with respect to our Orange Book listed patent for Zepzelca on the date of the receipt of the applicable notice. In September 2024, we filed patent infringement suits against these ANDA filers. For additional information on litigation involving this matter, see “Zepzelca Patent Litigation” in Note 9, Commitments and Contingencies—Legal Proceedings of the Notes to Consolidated Financial Statements, included in Part I of this Quarterly Report on Form 10‑Q.

We also currently rely in part on trade secret protection for several of our products, including Defitelio, and product candidates. Trade secret protection does not protect information or inventions if another party develops that information or invention independently and establishing that a competitor developed a product through trade secret misappropriation rather than through legitimate means may be difficult to prove. We seek to protect our trade secrets and other unpatented proprietary information in part through confidentiality and invention agreements with our employees, consultants, advisors and partners. Nevertheless, our employees, consultants, advisors and partners may unintentionally or willfully disclose our proprietary information to competitors, and we may not have adequate remedies for such disclosures. Moreover, if a dispute arises with our employees, consultants, advisors or partners over the ownership of rights to inventions, including jointly developed intellectual property, we could lose patent protection or the confidentiality of our proprietary information, and possibly also lose the ability to pursue the development of certain new products or product candidates.

Disruptions at FDA, including due to a reduction in FDA’s workforce and/or inadequate funding for FDA, could prevent FDA from performing normal functions on which our business relies, which could negatively impact our business.

The ability of FDA to review and approve new products or review other regulatory submissions can be affected by a variety of factors, including statutory, regulatory and policy changes, inadequate government budget and funding levels, a reduction in FDA’s workforce and its ability to hire and retain key personnel. Disruptions at FDA and other agencies may also increase the time to meet with and receive agency feedback, review and/or approve our submissions, conduct inspections, issue regulatory guidance, or take other actions that facilitate the development, approval and marketing of regulated products, which would adversely affect our business. In addition, government proposals to reduce or eliminate budgetary deficits may include reduced allocations to FDA and other related government agencies. For example, the current President Trump administration recently established the Department of Government Efficiency, which implemented a federal government hiring freeze and announced certain additional efforts to reduce federal government employee headcount, including by eliminating 3,500 employees from FDA. It is unclear how these executive actions or other potential actions by the Trump Administration or other parts of the federal government will impact FDA or other regulatory authorities that oversee our business. The reductions in FDA’s workforce and budgetary pressures could significantly impact the ability of FDA to timely review and process our regulatory submissions or take other actions critical to the marketing of our products which could have a material adverse effect on our business. For example, our recently acquired product candidate dordaviprone has a target PDUFA action date of

August 18, 2025. If approval of the dordaviprone NDA is granted by FDA, the approval may may not happen on or prior to the target PDUFA action date, including as a result of recent reductions in FDA’s workforce. Any delay in obtaining, or inability to obtain, regulatory approval of the dordaviprone NDA would delay or prevent commercialization of the resulting product and could increase our costs. As a result, the anticipated benefits of the Chimerix acquisition may not be realized fully within the expected timeframe or at all or may take longer to realize or cost more than expected, which could materially and adversely affect our business, financial condition, results of operations and growth prospects.
