Incyte (ICY) Risk Analysis

Our activities, and the activities of our collaborators, partners and third-party providers, are subject to extensive government regulation and oversight both in the United States and in foreign jurisdictions. The FDA and comparable agencies in other jurisdictions directly regulate many of our most critical business activities, including the conduct of preclinical and clinical studies, product manufacturing, advertising and promotion, product distribution, adverse event reporting and product risk management. States increasingly have been placing greater restrictions on the marketing practices of healthcare companies and have instituted pricing disclosure and other requirements for companies selling pharmaceuticals. In addition, pharmaceutical and biotechnology companies have been the target of lawsuits and investigations alleging violations of government regulations, including claims asserting submission of incorrect pricing information, improper promotion of pharmaceutical products, payments intended to influence the referral of federal or state healthcare business, submission of false claims for government reimbursement, antitrust violations, violations of the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act and similar anti-bribery or anti-corruption laws, or violations related to environmental matters. There is also enhanced scrutiny of company-sponsored patient assistance programs, including insurance premium and co-pay assistance programs and donations to third-party charities that provide such assistance, and we have previously been subject to an inquiry relating to our speaker programs and patient assistance programs. Violations of governmental regulation by us, our vendors or donation recipients may be punishable by criminal and civil sanctions, including damages, fines and penalties and exclusion from participation in government programs, including Medicare and Medicaid. In addition to damages, fines and penalties for violation of laws and regulations, we could be required to repay amounts we received from government payors, or pay additional rebates and interest if we are found to have miscalculated the pricing information we have submitted to the government. Actions taken by federal or local governments, legislative bodies and enforcement agencies with respect to these legal and regulatory compliance matters could also result in reduced demand for our products, reduced coverage of our products by healthcare payors, or both. We cannot ensure that our compliance controls, policies, and procedures will in every instance protect us from acts committed by our employees, collaborators, partners or third-party providers that would violate the laws or regulations of the jurisdictions in which we operate. Whether or not we have complied with the law, an investigation into alleged unlawful conduct could increase our expenses, damage our reputation, divert management time and attention and adversely affect our business, and any settlement of these proceedings could result in significant payments by us. Risks relating to compliance with laws and regulations may be heightened as we continue to expand our global operations and enter new therapeutic areas with different patient populations, which due to different product distribution methods, marketing programs or patient assistance programs may result in additional regulatory burdens and obligations.

Our revenue, results of operations, and cash flows could be materially and adversely affected by changes in government pricing policies, including recently proposed or enacted "most favored nation" (MFN) pricing legislation or executive actions. For example, an executive order issued on May 12, 2025, directed the Department of Health and Human Services to establish MFN price targets, and, if progress toward these targets is insufficient, to pursue rulemaking that could require sale of certain products in the U.S. at prices no higher than those in comparable developed nations. The extent, timing, and ultimate effect of this policy are uncertain, and we cannot predict the potential impact on our pricing, reimbursement, or profitability.

In order to commercialize drug products in the United States, drug candidates will have to obtain regulatory approval from the FDA. Satisfaction of regulatory requirements typically takes many years. To obtain regulatory approval, we or our collaborators, as the case may be, must first show that our or our collaborators' drug candidates are safe and effective for target indications through preclinical testing (animal testing) and clinical trials (human testing). Preclinical testing and clinical development are long, expensive and uncertain processes, and we do not know whether the FDA will allow us or our collaborators to undertake clinical trials of any drug candidates in addition to our or our collaborators' compounds currently in clinical trials. If regulatory approval of a product is granted, this approval will be limited to those disease states and conditions for which the product is demonstrated through clinical trials to be safe and effective. Completion of clinical trials may take several years and failure may occur at any stage of testing. The length of time required varies substantially according to the type, complexity, novelty and intended use of the drug candidate. Interim results of a preclinical test or clinical trial do not necessarily predict final results, and acceptable results in early clinical trials may not be repeated in later clinical trials. For example, a drug candidate that is successful at the preclinical level may cause harmful or dangerous side effects when tested at the clinical level. Our rate of commencement and completion of clinical trials may be delayed, and existing clinical trials with our or our collaborators' drug candidates may be stopped, due to many potential factors, including: - the high degree of risk and uncertainty associated with drug development;- our inability to formulate or manufacture sufficient quantities of materials for use in clinical trials;- variability in the number and types of patients available for each study;- difficulty in maintaining contact with patients after treatment, resulting in incomplete data;- unforeseen safety issues or side effects;- poor or unanticipated effectiveness of drug candidates during the clinical trials; or - government or regulatory delays. Data obtained from clinical trials are susceptible to varying interpretation, which may delay, limit or prevent regulatory approval. Many companies in the pharmaceutical and biopharmaceutical industry, including our company, have suffered significant setbacks in advanced clinical trials, even after achieving promising results in earlier clinical trials. In addition, regulatory authorities may refuse or delay approval as a result of other factors, such as changes in regulatory policy during the period of product development and regulatory agency review. Delays in FDA approval of drug candidates may also result from other factors such as funding limitations, staffing reductions or other resource restrictions, any of which could have an adverse effect on the regulatory approval process. Further, the FDA has in the past required, and could in the future require, that we or our collaborators conduct additional trials of any of our drug candidates, which would result in delays and could result in our termination of a drug development program. From time to time we and our collaborators have experienced events that have resulted in delays, setbacks and terminations of drug development programs. In April 2017, we and our collaborator Lilly announced that the FDA had issued a complete response letter for the NDA of OLUMIANT as a once-daily oral medication for the treatment of moderate-to-severe rheumatoid arthritis. The letter indicated that additional clinical data were needed to determine the most appropriate doses and to further characterize safety concerns across treatment arms. In June 2018, after a resubmission of the NDA, the FDA approved the 2mg dose of OLUMIANT for the treatment of adults with moderately-to-severely active rheumatoid arthritis who have had an inadequate response to one or more tumor necrosis factor inhibitor therapies. The FDA did not at that time approve any higher dose of OLUMIANT and required a warning label in connection with its approval. In addition, in January 2022, we announced that we withdrew the NDA seeking approval of parsaclisib for the treatment of patients with relapsed or refractory follicular lymphoma, marginal zone lymphoma and mantle cell lymphoma. The decision to withdraw the NDA followed discussions with FDA regarding confirmatory clinical trials that we determined cannot be completed within the time period to support the investment. Also, in March 2023, we received a complete response letter for ruxolitinib extended release tablets, which identified additional requirements for approval. Compounds or biologics developed by us or with or by our collaborators and licensees may not prove to be safe and effective in clinical trials and may not meet all of the applicable regulatory requirements needed to receive marketing approval. For example, in January 2020 we stopped our Phase 3 trial of itacitinib for the treatment of acute graft-versus-host-disease. If clinical trials of any of our or our collaborators' compounds or biologics are stopped for safety, efficacy or other reasons or fail to meet their respective endpoints, our overall development plans, business, prospects, expected operating results and financial condition could be materially harmed and the value of our company could be negatively affected. Even if any of our applications receives an FDA Fast Track or priority review designation (including based on a priority review voucher, one of which we recently acquired and used in connection with our submission seeking FDA approval of ruxolitinib cream for atopic dermatitis), these designations may not result in faster review or approval for our product candidate compared to product candidates considered for approval under conventional FDA procedures and, in any event, do not assure ultimate approval of our product candidate by the FDA. For example, in June 2021 we were informed by the FDA that the FDA had extended by three months the review period for the NDA for ruxolitinib cream for atopic dermatitis. Also, in July 2021, we announced that the FDA issued a complete response letter for the BLA of retifanlimab for the treatment of squamous cell carcinoma of the anal canal, in which the FDA stated it cannot approve the BLA and that additional data are needed. In addition, while the FDA had granted orphan drug designation and Fast Track designation to parsaclisib as a treatment for patients with follicular lymphoma, marginal zone lymphoma and mantle cell lymphoma, as discussed above we withdrew our NDA seeking approval for treatment of patients with those lymphomas. The FDA has recently increased its attention on mandated confirmatory trials for oncology drug candidates with accelerated approvals, and the logistics, cost and timing required for confirmatory trials may conflict with our investment thesis for drug candidates, resulting in withdrawal of approval applications. Outside the United States, our and our collaborators' ability to market a product is contingent upon receiving a marketing authorization from the appropriate regulatory authorities. This foreign regulatory approval process typically includes all of the risks associated with the FDA approval process described above and may also include additional risks. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from country to country and may require us to perform additional testing and expend additional resources. Approval by the FDA does not ensure approval by regulatory authorities in other countries, and approval by one foreign regulatory authority does not ensure approval by regulatory authorities in other countries or by the FDA.

In addition to establishing collaborative or license arrangements under which other parties license our drug candidates for development and commercialization or under which we study our drug candidates in combination with such parties' compounds or biologics, we may explore opportunities to develop our clinical pipeline by in-licensing drug candidates or therapeutic targets that fit within our focus, such as our collaborations with MacroGenics, Inc. ("MacroGenics"), Merus N.V. ("Merus") and Syndax Pharmaceuticals Inc., or explore additional opportunities to further develop and commercialize existing drug candidates in specific jurisdictions, such as our June 2016 acquisition of the development and commercialization rights to ICLUSIG in certain countries. We may be unable to enter into any additional in-licensing agreements because suitable drug candidates that are within our expertise may not be available to us on terms that are acceptable to us or because competitors with greater resources seek to in-license the same drug candidates. Drug candidates that we would like to develop or commercialize may not be available to us because they are controlled by competitors who are unwilling to license the rights to the drug candidate to us. In addition, we may enter into license agreements that are unsuccessful and our business and operations might be adversely affected if we are unable to realize the expected economic benefits of a collaboration or other licensing arrangement, by the termination of a drug candidate and termination and winding down of the related license agreement, or due to other business or regulatory issues, including financial difficulties, that may adversely affect a licensor's ability to continue to perform its obligations under an in-license agreement. For example, in January 2022, we decided to opt-out of the continued development with Merus of MCLA-145, which was the most advanced compound under our collaboration with Merus, and in 2022 and 2023, we decided to terminate our collaborations with Calithera Biosciences, Inc. and Syros Pharmaceuticals, Inc. If we make or incur contractual obligations to make significant upfront payments in connection with licenses for late-stage drug candidates, and if any of those drug candidates do not receive marketing approval or commercial sales as anticipated or we have to fund additional clinical trials before marketing approval can be obtained, we will have expended significant funds that might have been applied for other uses or we may have to expend funds that were not otherwise budgeted or anticipated in connection with the collaboration, and such developments could have a material adverse effect on our stock price and our ability to pursue other transactions. As discussed above under "Other Risks Relating to Our Business-We depend on our collaborators and licensees for the future development and commercialization of some of our drug candidates. Conflicts may arise between our collaborators and licensees and us, or our collaborators and licensees may choose to terminate their agreements with us, which may adversely affect our business," conflicts or other issues may arise with our licensors. Those conflicts could result in delays in our plans to develop drug candidates or result in the expenditure of additional funds to resolve those conflicts that could have an adverse effect on our results of operations. We have also licensed, and may in the future need to license, drug delivery or other technology in order to continue to develop our drug candidates. If we are unable to enter into additional agreements to license drug candidates, drug delivery technology or other technology or if these arrangements are unsuccessful, our research and development efforts could be adversely affected, and we may be unable to increase our number of successfully marketed products and our revenues.

We cannot guarantee that we will be able to maintain regulatory approval to market our products in the jurisdictions in which they are currently marketed. If we do not maintain our regulatory approval to market our products, our results of operations will be materially harmed. We and our collaborators, third-party manufacturers and suppliers are subject to rigorous and extensive regulation by the FDA and other federal and state agencies as well as foreign governmental agencies. These regulations continue to apply after product marketing approval, and cover, among other things, testing, manufacturing, quality control and assurance, labeling, advertising, promotion, risk mitigation, and adverse event reporting requirements. The commercialization of our products is subject to post-regulatory approval product surveillance, and our products may have to be withdrawn from the market or subject to restrictions if previously unknown problems occur. Regulatory agencies may also require additional clinical trials or testing for our products, and our products may be recalled or may be subject to reformulation, additional studies, changes in labeling, warnings to the public and negative publicity. For example, from late 2013 through 2014, ICLUSIG was subject to review by the European Medicines Agency ("EMA"), of the benefits and risks of ICLUSIG to better understand the nature, frequency and severity of events obstructing the arteries or veins, the potential mechanism that leads to these side effects and whether there needed to be a revision in the dosing recommendation, patient monitoring and a risk management plan for ICLUSIG. This review was completed in January 2015, with additional warnings in the product information but without any change in the approved indications. The EMA could take additional actions in the future that reduce the commercial potential of ICLUSIG. In addition, in September 2021, the FDA updated labeling for JAKAFI and other JAK inhibitor drugs to include warnings of increased risk of major adverse cardiovascular events, thrombosis, and secondary malignancies related to another JAK-inhibitor treating rheumatoid arthritis, a condition for which JAKAFI is not indicated. As part of the FDA labeling update for oral JAK inhibitors in treating inflammatory conditions, class "boxed" warnings were also included in the OPZELURA label. It is possible that future sales of JAKAFI and OPZELURA could be negatively affected as a result of the "boxed" warnings, which could have a material and adverse effect on our business, results of operations and prospects. Failure to comply with the laws and regulations administered by the FDA or other agencies could result in: - administrative and judicial sanctions, including warning letters;- fines and other civil penalties;- suspension or withdrawal of regulatory approval to market or manufacture our products;- interruption of production;- operating restrictions;- product recall or seizure;- injunctions; and - criminal prosecution. The occurrence of any such event may have a material adverse effect on our business. Furthermore, disruptions at the FDA and other regulatory agencies could prevent those agencies from performing normal business functions on which the operation of our business relies, which could negatively impact our business.

The testing, manufacturing, marketing and sale of our products could expose us to product liability and other risks. Side effects and other problems experienced by patients from the use of our products could: - lessen the frequency with which physicians decide to prescribe our products;- encourage physicians to stop prescribing our products to their patients who previously had been prescribed our products;- cause serious harm to patients that may give rise to product liability claims against us; and - result in our need to withdraw or recall our products from the marketplace. If our products are used by a wide patient population, new risks and side effects may be discovered, the rate of known risks or side effects may increase, and risks previously viewed as less significant could be determined to be significant. Previously unknown risks and adverse effects of our products may also be discovered in connection with unapproved, or off-label, uses of our products. We are prohibited by law from promoting or in any way supporting or encouraging the promotion of our products for off-label uses, but physicians are permitted to use products for off-label purposes. In addition, we are studying and expect to continue to study our approved products in diseases for potential additional indications in controlled clinical settings, and independent investigators are doing so as well. In the event of any new risks or adverse effects discovered as new patients are treated and as our products are studied in or used by patients for off-label indications, regulatory authorities may delay or revoke their approvals, we may be required to conduct additional clinical trials, make changes in labeling of our products, reformulate our products or make changes and obtain new approvals. We may also experience a significant drop in the sales of our products, experience harm to our reputation and the reputation of our products in the marketplace or become subject to lawsuits, including class actions. Any of these results could decrease or prevent sales of our products or substantially increase the costs and expenses of commercializing our products. Patients who have been enrolled in our clinical trials or who may use our products in the future often have severe and advanced stages of disease and known as well as unknown significant pre-existing and potentially life-threatening health risks. During the course of treatment, patients may suffer adverse events, including death, for reasons that may or may not be related to our products. Such events could subject us to costly litigation, require us to pay substantial amounts of money to injured patients, delay, negatively impact or end our opportunity to receive or maintain regulatory approval to market our products, or require us to suspend or abandon our commercialization efforts. Even in a circumstance in which we do not believe that an adverse event is related to our products, the investigation into the circumstance may be time consuming or inconclusive. These investigations may interrupt our sales efforts, impact and limit the type of regulatory approvals our products receive or maintain, or delay the regulatory approval process in other countries. Factors similar to those listed above also apply to our collaborators in the jurisdictions in which they have development and commercialization rights.
