Our inability to maintain revenues from our oxybate franchise would have a material adverse effect on our business, financial condition, results of operations and growth prospects.

Previous report

Historically, our business was substantially dependent on Xyrem, and our financial results were significantly influenced by sales of Xyrem. Our current 2025 operating plan assumes that Xywav, with 92% lower sodium compared to high-sodium oxybates (depending on the dose) and absence of a sodium warning, will remain the #1 branded oxybate treatment for narcolepsy; the position it held based on revenue in the third quarter of 2025. While we expect that our business will continue to be meaningfully dependent on oxybate revenues, there is no guarantee that oxybate revenues will remain at current levels. In this regard, our ability to maintain oxybate revenues and realize the anticipated benefits from our investment in Xywav are subject to a number of risks and uncertainties as discussed in greater detail below, including: those related to thecommercialization of Xywav for the treatment of IH in adults and adoption in that indication; competition from the introduction of AG versions of high-sodium oxybate and branded products, such as Avadel’s once-nightly dose, high-sodium oxybate branded product Lumryz, for treatment of cataplexy and/or EDS in adults with narcolepsy in the U.S. market, as well as potential future competition from additional AG and generic versions of high-sodium oxybate, including a generic version of high-sodium oxybate from Amneal approved in September 2025, and from other competitors; increased pricing pressure from, changes in policies by, or restrictions on reimbursement imposed by, third party payors, including our ability tomaintain adequate coverage and reimbursement for Xywav; increased rebates required to maintain access to our products; challenges to our intellectual property around Xyrem and/or Xywav, including from pending antitrust and intellectual property litigation; andcontinued acceptance of Xywav by physicians and patients. In addition, a wholly owned subsidiary of Hikma launched its AG version of high-sodium oxybate in January 2023 and Amneal launched its AG version of high-sodium oxybate in July 2023. For a discussion of risks associated with maintaining the AG royalty revenue from these AG products, see the risk factor below titled “The introduction of new products in the U.S. market that compete with, or otherwise disrupt the market for, our oxybate products has adversely affected and may continue to adversely affect sales of our oxybate products.” We have seen a negative impact and expect to see a further negative impact on our oxybate revenues as a result of these AG products and Avadel’s Lumryz and any generic products and new branded products that may compete with our oxybate products. A substantial decline in oxybate revenues could cause us to reduce our operating expenses or seek to raise additional funds and would have a material adverse effect on our business, financial condition, results of operations and growth prospects, including on our ability to acquire, in-license or develop new products to grow …

Previous report

The introduction of new products in the U.S. market that compete with, or otherwise disrupt the market for, our oxybate products has adversely affected and may continue to adversely affect sales of our oxybate products.

Previous report

New treatment options for cataplexy and EDS in narcolepsy have been commercially launched and, in the future, other products may be launched that are competitive with or disrupt the market for our oxybate products, Xywav and Xyrem.

Previous report

Ten companies have sent us notices that they had filed ANDAs seeking approval to market a generic version of Xyrem. We filed patent lawsuits against all ten companies and have settled with all ten of the companies. To date, FDA has approved or tentatively approved four of these ANDAs, and we believe that it is likely that FDA will approve or tentatively approve some or all of the others. Pursuant to our patent litigation settlement with the first filer, Hikma launched its AG version of high-sodium oxybate in the U.S. beginning on January 1, 2023. Accordingly, beginning in January 2023, Xywav and Xyrem face competition from an AG version of high-sodium oxybate. We also granted Hikma a license to launch its own generic high-sodium oxybate product but, if it elects to launch its own generic product, Hikma will no longer have the right to sell the Hikma AG product. In our settlements with Amneal, Lupin, and Par, we granted each party the right to sell a limited volume of an AG product in the U.S. beginning on July 1, 2023 and ending on December 31, 2025, with royalties to be paid to us. Amneal launched its AG version of high-sodium oxybate in July 2023. At this time, Amneal has rights to sell a low-single-digit percentage of historical Xyrem sales over each 6-month sales period. At this time, Lupin and Par have elected not to launch an AG product. AG products are distributed through the same REMS as Xywav and Xyrem. We also granted each of Amneal, Lupin and Par a license to launch its own generic high-sodium oxybate product under its ANDA on or after December 31, 2025, or earlier under certain circumstances, including the circumstance where Hikma elects to launch its own generic product. In September 2025, Amneal received FDA approval for a generic version of high-sodium oxybate. If Amneal, Lupin or Par elects to launch its own generic product under such circumstance, it will no longer have the right to sell an AG product. In our settlements with each of six other ANDA filers, we granted each a license to launch its own generic high-sodium oxybate product under its ANDA on or after December 31, 2025, or earlier under certain circumstances, including circumstances where Hikma launches its own generic high-sodium oxybate product. It is possible that additional companies may file ANDAs seeking to market a generic version of Xyrem which could lead to additional patent litigation or challenges with respect to Xyrem and/or additional competition for our oxybate products.

Previous report

Any ANDA holder launching an AG product or another generic high-sodium oxybate product will independently establish the price of the AG product and/or its own generic high-sodium oxybate product and determine the types of discounts or rebates they will offer parties that purchase or pay for the product. Generic competition often results in decreases in the net prices at which branded products can be sold. A component of drug pricing is the manufacturer’s list price for a drug to wholesalers or direct purchasers in the U.S. (without discounts, rebates or other reductions) referred to as the WAC. In this regard, Hikma and Amneal launched their AG products in 2023 at a WAC that was less than 15% lower than the WAC for Xyrem. After any introduction of a generic product, whether or not it is an AG product, a significant percentage of the prescriptions written for Xyrem have been, and will likely continue to be, filled with the generic product. Certain U.S. state laws allow for, and in some instances in the absence of specific instructions from the prescribing physician mandate, the dispensing of generic products rather than branded products when a generic version is available. This has resulted in reduced sales of, and revenue from, Xyrem. We continue to receive royalties and other revenue based on sales of AG products in accordance with the terms of our settlement agreements.

Previous report

Other companies may develop sodium oxybate products for the treatment of narcolepsy, using an alternative formulation or a different delivery technology, and seek approval in the U.S. using an NDA approval pathway under Section 505(b)(2) and referencing the safety and efficacy data for Xyrem. For example, we face competition from branded products for treatment of cataplexy and/or EDS in narcolepsy, such as Avadel’s Lumryz. On May 1, 2023, Avadel announced that it had received FDA approval and ODE through May 1, 2030 for Lumryz, a fixed-dose, high-sodium oxybate which uses its proprietary technology for the treatment of EDS and cataplexy in patients with narcolepsy. Xyrem and Xywav also face increased competition from other branded entrants to treat EDS in narcolepsy such as Wakix and Sunosi. Other companies have announced that they have product candidates in various phases of development to treat the symptoms of narcolepsy, such as Axsome’s reboxetine, and various companies are performing research and development on orexin agonists for the treatment of sleep disorders, including Takeda Pharmaceutical Company Limited and Alkermes plc.

Previous report

We expect that Xywav for the treatment of both cataplexy and EDS in patients with narcolepsy will continue to face competition from generic or AG high-sodium oxybate products or branded entrants in narcolepsy, such as Avadel’s Lumryz, notwithstanding FDA recognizing ODE for Xywav. For example, we received notices in June 2021 and February 2023, that Lupin and Teva, respectively, filed ANDAs for generic versions of Xywav. On October 13, 2023, Lupin announced that it has received tentative approval for its application to market a generic version of Xywav. In addition, in July 2025, we received notice from Granules that it has filed with FDA an ANDA for a generic version of Xywav. We have filed patent infringement suits against these ANDA filers. For additional information see “Xywav Patent Litigation” in Note 10, Commitments and Contingencies—Legal Proceedings of the Notes to Consolidated Financial Statements, included in Part I of this Quarterly Report on Form 10‑Q. Additional companies may file ANDAs seeking to market a generic version of Xywav which could lead to additional patent litigation or challenges with respect to Xywav and/or additional competition.

Previous report

Moreover, generic or AG high-sodium oxybate products or branded high-sodium oxybate entrants in narcolepsy, such as Avadel’s Lumryz, as well as non-oxybate products intended for the treatment of EDS or cataplexy in narcolepsy or IH including new market entrants, even if not directly competitive with Xywav or Xyrem, have had and may continue to have the effect of changing treatment regimens and payor or formulary coverage of Xywav or Xyrem in favor of other products, and indirectly adversely affect sales of Xywav and Xyrem. Examples of such new market entrants of non-oxybate products include Wakix (pitolisant), a drug that was approved by FDA in 2019 for the treatment of EDS in adult patients with narcolepsy and approved by FDA in 2020 for an adult cataplexy indication in the U.S. Wakix has also been approved and marketed in Europe to treat adult patients with narcolepsy, with or without cataplexy, and to treat EDS in obstructive sleep apnea. Harmony Biosciences has announced a phase 3 study for pitolisant for IH after receiving a refusal to file from FDA in February 2025. In addition, we are also aware that prescribers often prescribe branded or generic medications for cataplexy and IH, before or instead of prescribing oxybate therapy including Xywav and Xyrem, and that payors often require patients to try such medications before they will cover Xywav or Xyrem, even if they are not approved for this use. Examples of such products are described in “Business—Competition” in Part I, Item 1 of our Annual Report on Form 10‑K for the year ended December 31, 2024.

Previous report

We expect that the approval and launch of AG products or other generic versions of Xyrem or Xywav and the approval and launch of any other sodium oxybate product, such as Avadel’s Lumryz, or alternative product that treats narcolepsy will continue to have a negative impact on, and could have a material adverse effect on, our sales of Xywav and Xyrem and on our business, financial condition, results of operations and growth prospects.

Recent executive and judicial changes and flux in the regulatory landscape creates uncertainty for us and our industry.

Previous report

The current administration is pursuing policies to reduce regulations and expenditures across government including at HHS, FDA, CMS and related agencies. These actions, primarily directed by executive orders or memoranda from the Office of Management and Budget, may propose policy changes that create additional uncertainty for our business. For example, on September 30, 2025, the current administration announced the first agreement with a major pharmaceutical company that requires the drug manufacturer to offer, through a direct to consumer platform, U.S. patients and Medicaid programs prescription drug Most-Favored Nation pricing equal to or lower than those paid in other developed nations, with additional mandates for direct-to-patient discounts and repatriation of foreign revenues. Other recent actions have included directives and actions to reduce agency workforce, program cuts, rescinding a Biden administration executive order tasking the Center for Medicare & Medicaid Innovation to consider new payment and healthcare models to limit drug spending, eliminating the Biden administration’s executive order that directed HHS to establish an AI task force and develop a strategic plan and directing certain federal agencies to enforce existing law regarding hospital and price plan transparency and by standardizing prices across hospitals and health plans and, as part of the Make America Healthy Again (also referred to as MAHA) Commission’s recent Strategy Report, working across government agencies to increase enforcement on direct-to-consumer pharmaceutical advertising. These actions and policies may significantly reduce U.S. drug prices, potentially impacting manufacturers’ global pricing strategies and profitability, while increasing their operational costs and compliance risks. Additionally, in its June 2024 decision in Loper Bright, the U.S. Supreme Court overturned the longstanding Chevron doctrine, under which courts were required to give deference to regulatory agencies’ reasonable interpretations of ambiguous federal statutes. The Loper Bright decision could result in additional legal challenges to current regulations and guidance issued by federal agencies applicable to our operations, including those issued by FDA. Finally, Congress may introduce and ultimately pass health care related legislation that could impact the drug approval process and make changes to the Medicare Drug Price Negotiation Program created under the IRA. We cannot predict which additional measures may be adopted or the impact of current and additional measures on the marketing, pricing and demand for our products, which could have a material adverse effect on our business, financial condition and results of operations.

Previous report

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.

Previous report

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. In addition, policymakers and federal agencies, including the Centers for Medicare & Medicaid Innovation, have signaled interest in testing or advancing new drug pricing models—such as so-called “most favored nation” or international reference pricing approaches—that would tie U.S. reimbursement levels to prices in foreign markets. Any such initiatives, if implemented, could reduce reimbursement for certain products, exert downward pricing pressure, and adversely affect our revenues and profitability. 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. In addition, under the Medicaid Drug Rebate Program, r…

On July 4, 2025, President Trump signed into law H.R.1, a budget bill, which includes significant reforms to Medicaid, Medicare, and Affordable Care Act premium tax credits. Among other things, these reforms are anticipated to significantly decrease Medicaid spending, which could reduce access to and reimbursement for our products, which could have a negative adverse effect on our revenues.

Previous report

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. Moreover, on April 15, 2025, the White House issued an executive order announcing a number of initiatives seeking to lower drug pricing. In addition, there has been recent interest in incorporating so-called Most Favored Nation pricing into the U.S. healthcare system, under which prices for drugs in the United States could be tied to foreign reference prices through a mechanism that is not yet defined, announced in a second executive order dated May 12, 2025. 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.

Previous report

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.

Previous report

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.

Previous report

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.

Previous report

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 reimbursement price of medicinal products to be assessed against the relative price and cost of treatment of existing standard of care and competitor products, which may hinder the inclusion of newer innovative products in reimbursement lists. 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. The European Parliament and the Council of the European Union are currently engaged in interinstitutional negotiations to agree on the final version of the pharmaceutical legislation. 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.

Previous report

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.

Previous report

The ongoing trade tensions between the U.S. and other jurisdictions have resulted in multiple rounds of tariffs and anticipated tariffs affecting pharmaceuticals and pharmaceutical ingredients, including finished drug products, manufacturing equipment, and related supplies. Such tariffs may significantly increase our costs for certain products. The Bureau of Industry and Security, U.S. Department of Commerce, has initiated an investigation to determine whether pharmaceutical ingredients, including finished drug product, manufactured outside the United States pose a national security risk and should be subject to additional tariffs. Should current tariffs hold or additional tariffs be imposed specifically targeting pharmaceutical imports, 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. In addition, the dynamic and unpredictable tariff and trade landscape creates substantial uncertainty and significant planning challenges for our operations. Changes in tariff classifications, country-of-origin requirements, or customs procedures can occur with limited notice. This uncertainty complicates our long-term investment decisions regarding manufacturing facilities, supply chain optimization, and research and development locations.

Previous report

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.

Previous report

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.

Previous report

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, Modeyso, which we acquired in the acquisition, may not be successful or 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.

Previous report

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.

Previous report

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.

Previous report

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:
