Pfizer (PFE) Risk Analysis

The discovery and development of new products, as well as the development of additional uses for existing products, are necessary for the continued strength of our business. Our product lines must be replenished over time to offset revenue losses when products lose exclusivity or market share or to respond to healthcare and innovation trends, as well as to provide for earnings growth, primarily through internal R&D or through collaborations, acquisitions, JVs, licensing or other arrangements. Growth depends in large part on our ability to identify and develop new products or new indications for existing products that address unmet medical needs and receive reimbursement from payers. However, balancing current growth, investment for future growth and the delivery of shareholder return remains a major challenge. The costs of product development continue to be high, as are regulatory requirements in many therapeutic areas, which may affect the number of candidates we are able to fund as well as the sustainability of the R&D portfolio. Decisions made early in the development process of a drug or vaccine candidate can have a substantial impact on the marketing strategy and payer reimbursement possibilities if the candidate receives regulatory approval. We try to plan clinical trials prudently and to reasonably anticipate and address challenges, but there is no assurance that an optimal balance between trial conduct, speed and desired outcome will be achieved. Additionally, our product candidates can fail at any stage of the R&D process, and may not receive regulatory approval even after many years of R&D. We may fail to correctly identify indications for which our science is promising or allocate R&D investment resources efficiently, and failure to invest in the right technology platforms, therapeutic areas, product classes, geographic markets and/or licensing opportunities could adversely impact the productivity of our pipeline. Further, even if we identify areas with the greatest commercial potential, the scientific approach may not succeed despite the significant investment required for R&D, and the product may not be as competitive as expected because of the highly dynamic market environment and the hurdles in terms of access and reimbursement. For example, our gene therapy product candidates are based on a novel technology with only a few gene therapies approved to date, which makes it difficult to predict the time and cost of development and the ability to obtain regulatory approval. Further, gene therapy may face difficulties in gaining the acceptance of patients or the medical community.

Our success largely depends on our ability to market technologically competitive products. We rely and expect to continue to rely on a combination of intellectual property, including patent, trademark, trade dress, copyright, trade secret and domain name protection laws, as well as confidentiality and license agreements, to protect our intellectual property and proprietary rights. If we fail to obtain and maintain adequate intellectual property protection, we may not be able to prevent third parties from launching generic or biosimilar versions of our branded products, from using our proprietary technologies or from marketing products that are very similar or identical to ours. Our currently pending or future patent applications may not result in issued patents or be granted on a timely basis. Similarly, any term extensions that we seek may not be granted on a timely basis, if at all. In addition, our issued patents may not contain claims sufficiently broad to protect us against claims regarding validity, enforceability, scope and effective term made by parties with similar technologies or products or provide us with any competitive advantage, including exclusivity in a particular product area. Further, legal or regulatory action by various stakeholders or governments could potentially result in us not seeking intellectual property protection for or agreeing not to enforce or being restricted from enforcing intellectual property related to our products. The WTO continues to address the role of intellectual property in the context of the COVID-19 pandemic response. This includes the June 2022 Ministerial Decision on the Agreement on Trade-Related Aspects of Intellectual Property Rights, which seeks to make it easier for certain WTO members to issue a compulsory license on COVID-19 vaccines, and discussions continue on whether to expand that decision to COVID-19 therapeutics and diagnostics. The scope of our patent claims also may vary between countries, as individual countries have distinct patent laws, and our ability to enforce our patents depends on the laws of each country, its enforcement practices, and the extent to which certain countries engage in policies or practices that weaken a country’s intellectual property framework (e.g., laws or regulations that promote or provide broad discretion to issue a compulsory license). In countries that provide some form of regulatory exclusivity, mechanisms exist permitting some form of challenge to our patents by competitors or generic drug marketers prior to or immediately following the expiration of such regulatory exclusivity, and generic companies are employing aggressive strategies, such as “at risk” launches that challenge our patent rights. Most of the suits involve claims by generic drug manufacturers that patents covering our products, uses, processes or dosage forms are invalid and/or do not cover the product of the generic or biosimilar drug manufacturer. Independent actions have been filed alleging that our assertions of, or attempts to enforce, patent rights with respect to certain products constitute unfair competition and/or violations of antitrust laws. Such claims may also be brought as counterclaims to actions we bring to enforce our patents. We are also party to other patent damages suits in various jurisdictions pursuant to which generic drug manufacturers, payers, governments or other parties are seeking damages from us for alleged delay of generic entry. We also are often involved in other proceedings, such as inter partes review, post-grant review, re-examination or opposition proceedings, before the U.S. Patent and Trademark Office, the European Patent Office, or other foreign counterparts relating to our intellectual property or the intellectual property rights of others. Also, if one of our patents or a competitors’ patents is found to be invalid in such proceedings, generic or biosimilar products could be introduced into the market resulting in the erosion of sales of our existing products. For additional information, including information regarding certain legal proceedings in which we are involved, see Note 16A1. Further, if we are unable to maintain our existing license agreements or other agreements pursuant to which third parties grant us rights to intellectual property, our operating results and financial condition could be adversely affected. We currently hold trademark registrations and have trademark applications pending in many jurisdictions, any of which may be the subject of a governmental or third-party objection, which could prevent the maintenance or issuance of the trademark. As our products mature, our reliance on our trademarks and trade dress to differentiate us from our competitors increases and, as a result, our business could be adversely affected if we are unable to prevent third parties from adopting, registering or using trademarks and trade dress that infringe, dilute or otherwise violate our rights. We seek to protect our proprietary information, including our trade secrets and proprietary know-how, by requiring our employees, consultants, other advisors and other third parties to execute proprietary information and confidentiality agreements upon the commencement of their relationship with us. Despite these efforts and precautions, we may be unable to prevent a third-party from copying or otherwise obtaining and using our trade secrets or our other intellectual property without authorization, and legal remedies may not adequately compensate us for the damages caused by such unauthorized use. Further, others may independently and lawfully develop substantially similar or identical products that circumvent our intellectual property by means of alternative designs or processes or otherwise.

U.S. and international governmental regulations that mandate price controls or limitations on patient access to our products or establish prices paid by government entities or programs for our products impact our business, and our future results could be adversely affected by changes in such regulations or policies. The adoption of restrictive price controls in new jurisdictions, more restrictive controls in existing jurisdictions or the failure to obtain or maintain timely or adequate pricing could also adversely impact revenue. We expect pricing pressures will continue globally. In the U.S., pharmaceutical product pricing is subject to government and public scrutiny and calls for reform, and many of our products are subject to increasing pricing pressures as a result. We expect to see continued focus by the Federal government on regulating pricing which could result in legislative and regulatory changes designed to control costs. For example, in August 2022, the IRA was signed into law, which, among other things, requires manufacturers of certain drugs to engage in price negotiations with Medicare, imposes rebates under Medicare Part B and Medicare Part D to penalize price increases that outpace inflation, and replaces the Part D coverage gap discount program with a new discounting program. Some states have implemented, and others are considering, patient access constraints or cost cutting under the Medicaid program, and some are considering measures that would apply to broader segments of their populations that are not Medicaid-eligible. State legislatures also have continued to focus on addressing drug costs, generally by increasing price transparency or limiting drug price increases. Measures to regulate prices or payment for pharmaceutical products, including legislation on drug importation, could adversely affect our business. For additional information on U.S. pricing and reimbursement, see the Item 1. Business—Government Regulation and Price Constraints section in this Form 10-K. We encounter similar regulatory and legislative issues in most other countries in which we operate. In certain markets, such as in EU member states, the U.K., Japan, China, Canada and South Korea, governments have significant power as large single payers to regulate prices, access criteria, or impose other means of cost control, particularly as a result of recent global financing pressures. For example, the QCE and VBP tender process in China has resulted in significant price cuts for off-patent medicines. For additional information regarding these government initiatives, see the Item 1. Business—Government Regulation and Price Constraints section in this Form 10-K. We anticipate that these and similar initiatives will continue to increase pricing pressures in China and elsewhere in the future. In addition, in many countries, with respect to our vaccines, we participate in a tender process for selection in national immunization programs. Failure to secure participation in national immunization programs or to obtain acceptable pricing in the tender process could adversely affect our business. We also anticipate pricing pressures will be amplified by COVID-19 induced budget deficits and focus on pricing for COVID-19 treatments and vaccines.

We recorded direct product and/or Alliance revenues of more than $1 billion for each of ten products that collectively accounted for 82% of our total revenues in 2022. In particular, Comirnaty and Paxlovid together accounted for 57% of our total revenues in 2022. For additional information, see Notes 1 and 17. If these products or any of our other major products were to experience loss of patent protection (if applicable), changes in prescription or vaccination purchasing or growth rates, reduced product demand, material product liability litigation, unexpected side effects or safety concerns, regulatory proceedings or investigations, lower governmental and/or regulatory confidence, negative publicity affecting doctor or patient confidence, pressure from competitive products, changes in labeling, pricing and access pressures or supply shortages or if a new, more effective product should be introduced, the adverse impact on our revenues could be significant. In particular, certain of our products have experienced patent-based expirations or loss of regulatory exclusivity in certain markets in the last few years, and patents covering a number of our best-selling products are, or have been, the subject of pending legal challenges. For additional information on our patents, see the Item 1. Business—Patents and Other Intellectual Property Rights section in this Form 10-K. For Comirnaty and Paxlovid, while we believe that these products have the potential to provide ongoing revenue streams for Pfizer for the foreseeable future, revenues of these products following the COVID-19 pandemic may not be at similar levels as those generated during the pandemic. For 2023, our revenue guidance for Comirnaty and Paxlovid as of January 31, 2023 is significantly lower than the 2022 revenues from these products. For information on risks associated with Comirnaty and Paxlovid, see the COVID-19 section below. In addition, we sell our prescription biopharmaceutical products, with the exception of Paxlovid, principally to wholesalers, but we also sell directly to retailers, hospitals, clinics, government agencies and pharmacies. In 2022, we principally sold Paxlovid to government agencies. We primarily sell our vaccines in the U.S. directly to the federal government, CDC, wholesalers, individual provider offices, retail pharmacies and integrated delivery systems. Outside the U.S., we primarily sell our vaccines to government and non-government institutions. For additional information, see Note 17C. If one of our significant customers should encounter financial or other difficulties, it might decrease the amount of business such customer does with us and/or we might be unable to timely collect all the amounts that such customer owes us or at all, which could negatively impact our results of operations. In addition, we expect that consolidation and integration of pharmacy chains and wholesalers will increase competitive and pricing pressures on pharmaceutical manufacturers, including us.

COVID-19 has impacted and may continue to impact our business, operations and financial condition and results. COVID-19-related risks and challenges for our business, include, among others: decreased product demand, due to reduced new prescriptions or refills of existing prescriptions and reduced demand for products used in procedures, or as a result of unemployment or increased focus on COVID-19 vaccination; impacts due to travel limitations and mobility restrictions in some jurisdictions; manufacturing disruptions and delays; supply chain disruptions and shortages, including challenges related to reliance on third-party suppliers resulting in reduced availability of materials or components used in the development, manufacturing, distribution or administration of our products; disruptions to pipeline development and clinical trials, including challenges related to enrolling certain clinical trials and accruing a sufficient number of cases in certain clinical trials; challenges presented by reallocating resources to assist in responding to COVID-19; costs associated with COVID-19, including increased supply chain costs and additional R&D costs incurred in our efforts to develop Comirnaty and Paxlovid; challenges related to our business development initiatives; interruptions or delays in the operations of regulatory authorities, which may delay potential approval of new products we are developing, potential label expansions for existing products and the launch of newly-approved products; challenges operating in a virtual or hybrid work environment; increased cyber threats and attack attempts; challenges related to our intellectual property, both domestically and internationally, including in response to any pressure, or legal or regulatory action by, various stakeholders or governments that could potentially result in us not seeking intellectual property protection for or agreeing not to enforce or being restricted from enforcing intellectual property rights related to our products, including Comirnaty and Paxlovid; challenges related to conducting oversight and monitoring of regulated activities in a virtual or hybrid environment; challenges related to our human capital and talent development; challenges related to vaccine mandates; and other challenges presented by disruptions to our normal operations in response to COVID-19, as well as uncertainties regarding the impact of COVID-19, and government or regulatory actions to contain the virus or control the supply of medicines and vaccines. The extent to which COVID-19 impacts our business going forward will depend on many factors, and we have made certain assumptions regarding COVID-19 for purposes of our operational planning and financial projections, including assumptions regarding the global macroeconomic impact of COVID-19, as well as the demand, revenues, supply, contracts and commercial markets for our COVID-19 products, which remain dynamic. Despite careful tracking and planning, we are unable to accurately predict the extent of the impact of COVID-19 on our business, operations and financial condition and results due to the uncertainty of future developments. In particular, we believe the ultimate impact on our business, operations and financial condition and results will be affected by, among other things, the emergence, infectiousness and severity of the predominant strains of the SAR-CoV-2 virus, the safety, efficacy, availability and public adherence of vaccines, boosters and treatments for COVID-19, proportion of the population that receives a vaccine or treatment for COVID-19, patient demand and market share for Comirnaty and Paxlovid, timing for delivery, and potential other amendments to the terms, of contracted doses or treatment courses to certain markets, timing and effectiveness for the expected transition to the commercial market for Comirnaty and Paxlovid, the global macroeconomic impact of COVID-19 and governmental responses or regulatory actions to contain the virus or control supply of medicines and vaccines. COVID-19 may also affect our business, operations or financial condition and results in a manner that is not presently known to us or that we currently do not consider as presenting significant risks. We also face risks and uncertainties related to our efforts to develop and commercialize our COVID-19 products, as well as challenges related to their manufacturing, supply and distribution, including, among others: •uncertainties inherent in R&D, including the ability to meet anticipated clinical endpoints, commencement and/or completion dates for clinical trials, regulatory submission dates, regulatory approval dates and/or launch dates, as well as risks associated with pre-clinical and clinical data (including Phase 1/2/3 or Phase 4 data for Comirnaty, any monovalent, bivalent or variant-adapted vaccine candidates or any other vaccine candidate in the BNT162 program or Paxlovid or any future COVID-19 treatment) in any of our studies in pediatrics, adolescents or adults or real world evidence, including the possibility of unfavorable new pre-clinical, clinical or safety data and further analyses of existing pre-clinical, clinical or safety data or further information regarding the quality of pre-clinical, clinical or safety data, including by audit or inspection; •the ability to produce comparable clinical or other results for Comirnaty, any monovalent, bivalent or variant-adapted vaccine candidates or other vaccines that may result from the BNT162 program, Paxlovid or any future COVID-19 treatment or any other COVID-19 program, including the rate of effectiveness and/or efficacy, safety and tolerability profile observed to date, in additional analyses of the Phase 3 trial for any such products and additional studies, in real-world data studies or in larger, more diverse populations following commercialization; •the ability of Comirnaty, any monovalent, bivalent or variant-adapted vaccine candidates or any future vaccine to prevent, or Paxlovid or any future COVID-19 treatment to be effective against, COVID-19 caused by emerging virus variants; •the risk that demand for any products may be reduced, no longer exist or not meet expectations, which may lead to excess inventory on-hand and/or in the channel or reduced revenues; •challenges related to a transition to the commercial market for any of our products; •uncertainties related to the public’s adherence to vaccines, boosters and treatments; •the risk that more widespread use of Comirnaty or Paxlovid will lead to new information about efficacy, safety or other developments, including the risk of additional adverse reactions, some of which may be serious; •the risk that pre-clinical and clinical trial data are subject to differing interpretations and assessments, including during the peer review/publication process, in the scientific community generally, and by regulatory authorities; •whether and when additional data from the BNT162 mRNA vaccine program, Paxlovid or other COVID-19 programs will be published in scientific journal publications and, if so, when and with what modifications and interpretations; •whether regulatory authorities will be satisfied with the design of and results from existing or future pre-clinical and clinical studies; •whether and when submissions to request emergency use or conditional marketing authorizations for Comirnaty or any future vaccines in additional populations, for a potential booster dose for Comirnaty, any monovalent or bivalent vaccine candidates or any potential future vaccines (including potential future annual boosters or re-vaccinations), and/or biologics license and/or EUA applications or amendments to any such applications may be filed in particular jurisdictions for Comirnaty, any monovalent or bivalent vaccine candidates or any other potential vaccines that may arise from the BNT162 program, including a potential variant-based, higher dose, or bivalent vaccine or any other potential vaccines, and if obtained, whether or when such EUA or licenses, or existing EUAs, will expire or terminate; •whether and when submissions to request emergency use or conditional marketing authorizations for Paxlovid or any future COVID-19 treatment and/or any drug applications and/or EUA applications or amendments to any such applications for any indication for Paxlovid or any future COVID-19 treatment may be filed in particular jurisdictions, and if obtained, whether or when such EUA or licenses, or existing EUAs, will expire or terminate; •whether and when any application that may be pending or filed for Comirnaty, any monovalent, bivalent or variant-adapted vaccine candidates or other vaccines that may result from the BNT162 program, Paxlovid or any future COVID-19 treatment or any other COVID-19 program may be approved by particular regulatory authorities, which will depend on myriad factors, including making a determination as to whether the vaccine’s or drug’s benefits outweigh its known risks and determination of the vaccine’s or drug’s efficacy and, if approved, whether it will be commercially successful; •decisions by regulatory authorities impacting labeling or marketing, manufacturing processes, safety and/or other matters that could affect the availability or commercial potential of a vaccine or drug, including the authorization or approval of products or therapies developed by other companies; •disruptions in the relationships between us and our collaboration partners, clinical trial sites or third-party suppliers, including our relationship with BioNTech; •the risk that other companies may produce superior or competitive products; risks related to the availability of raw materials to manufacture or test any such products; •challenges related to our vaccine’s formulation, dosing schedule and attendant storage, distribution and administration requirements, including risks related to storage and handling after delivery by us; •challenges and risks related to medication errors such as prescribing or dispensing the wrong strength, improper dosing and self-administration errors; •the risk that we may not be able to successfully develop other vaccine formulations, booster doses or potential future annual boosters or re-vaccinations or new variant-based or next generation vaccines or next generation COVID-19 treatments; •the risk that we may not be able to recoup costs associated with our R&D and manufacturing efforts; •risks associated with any changes in the way we approach or provide research funding for the BNT162 program, Paxlovid or any other COVID-19 program; •challenges and risks associated with the pace of our development programs; •the risk that we may not be able to maintain manufacturing capacity or access to logistics or supply channels commensurate with global demand for our COVID-19 products, which would negatively impact our ability to supply our COVID-19 products within the projected time periods; •risks related to our ability to achieve our revenue forecasts for Comirnaty and Paxlovid or any potential future COVID-19 vaccines or treatments; •whether and when additional supply or purchase agreements will be reached or existing agreements will be completed or renegotiated; •uncertainties regarding the ability to obtain recommendations from vaccine or treatment advisory or technical committees and other public health authorities and uncertainties regarding the commercial impact of any such recommendations; •pricing and access challenges for such products; •challenges related to public confidence in, or awareness of Comirnaty or Paxlovid, including challenges driven by misinformation or disinformation, access, concerns about clinical data integrity, or prescriber and pharmacy education; •uncertainties around future changes to applicable healthcare policies and guidelines issued by the U.S. federal government in connection with the declared termination of the federal government’s COVID-19 public health emergency as of May 11, 2023; •trade restrictions; •the risk that we may owe third-party royalties or have other claims asserted related to Comirnaty or Paxlovid; and •competitive developments.
