TABLE OF CONTENTS

PART I
ITEM 1.BUSINESS
ABOUT PFIZER

Pfizer Inc. is a research-based, global biopharmaceutical company. We apply science and our global resources to bring therapies to people that extend and significantly improve their lives through the discovery, development and manufacture of healthcare products. Our global portfolio includes medicines and vaccines, as well as many of the world’s best-known consumer healthcare products. We work across developed and emerging markets to advance wellness, prevention, treatments and cures that challenge the most feared diseases of our time. We collaborate with healthcare providers, governments and local communities to support and expand access to reliable, affordable healthcare around the world. Our revenues are derived from the sale of our products and, to a much lesser extent, from alliance agreements, under which we co-promote products discovered or developed by other companies or us. The majority of our revenues come from the manufacture and sale of biopharmaceutical products. The Company was incorporated under the laws of the State of Delaware on June 2, 1942.

We believe that our medicines provide significant value for both healthcare providers and patients, not only from the improved treatment of diseases but also from a reduction in other healthcare costs, such as emergency room or hospitalization costs, as well as improvements in health, wellness and productivity. We continue to actively engage in dialogues about the value of our medicines and how we can best work with patients, physicians and payers to prevent and treat disease and improve outcomes. We continue to work within the current legal and pricing structures, as well as continue to review our pricing arrangements and contracting methods with payers, to maximize patient access and minimize any adverse impact on our revenues. We remain firmly committed to fulfilling our company’s purpose of innovating to bring therapies to patients that extend and significantly improve their lives. By doing so, we expect to create value for the patients we serve and for our shareholders.

We are committed to capitalizing on growth opportunities by advancing our own pipeline and maximizing the value of our in-line products, as well as through various forms of business development, which can include alliances, licenses, joint ventures, collaborations, equity- or debt-based investments, dispositions, mergers and acquisitions. We view our business development activity as an enabler of our strategies, and we seek to generate earnings growth and enhance shareholder value by pursuing a disciplined, strategic and financial approach to evaluating business development opportunities.

Our significant recent business development activities include:

On February 3, 2017, we completed the sale of our global infusion systems net assets, HIS, to ICU Medical for up to approximately $900 million, composed of cash and contingent cash consideration, ICU Medical common stock and seller financing. HIS, which was acquired as part of the Hospira acquisition in September 2015, includes IV pumps, solutions and devices.

On December 22, 2016, for $1,045 million we acquired the development and commercialization rights to AstraZeneca’s small molecule anti-infectives business, primarily outside the U.S., which includes the newly approved EU drug Zavicefta™ (ceftazidime-avibactam), the marketed agents Merrem™/Meronem™ (meropenem) and Zinforo™ (ceftaroline fosamil), and the clinical development assets aztreonam-avibactam and ceftaroline fosamil-avibactam.

On September 28, 2016, we acquired Medivation for approximately $14.3 billion in cash ($13.9 billion, net of cash acquired). Medivation is a biopharmaceutical company focused on developing and commercializing small molecules for oncology.

On June 24, 2016, we acquired Anacor for approximately $4.9 billion in cash ($4.5 billion net of cash acquired), plus $698 million debt assumed. Anacor is a biopharmaceutical company focused on novel small-molecule therapeutics derived from its boron chemistry platform.

On September 3, 2015, we acquired Hospira, a leading provider of sterile injectable drugs and infusion technologies as well as a provider of biosimilars, for approximately $16.1 billion in cash ($15.7 billion, net of cash acquired).

For a further discussion of our strategy and our business development initiatives, see the Notes to Consolidated Financial Statements—Note 2. Acquisitions, Sale of Hospira Infusion Systems Net Assets, Research and Development and Collaborative Arrangements, Equity-Method Investments and Cost-Method Investment and the Overview of Our Performance, Operating Environment, Strategy and OutlookOur StrategyOur Business Development Initiatives section in our 2017 Financial Report.

Our businesses are heavily regulated in most of the countries in which we operate. In the U.S., the principal authority regulating our operations is the FDA. The Pfizer-BioNTech COVID-19 Vaccine (2023-2024 Formula) has been authorized for emergency use by the FDA regulatesunder an EUA to prevent COVID-19 in individuals aged 6 months through 11 years of age. Paxlovid has been authorized for emergency use by the FDA under an EUA for the treatment of mild-to-moderate COVID-19 in pediatric patients (12 years of age and older weighing at least 40 kg) who are at high risk for progression to severe COVID-19, including hospitalization or death. The emergency uses are only authorized for the duration of the declaration that circumstances exist justifying the authorization of emergency use of the medical product during the COVID-19 pandemic under Section 564(b)(1) of the FFDCA, unless the declaration is terminated or authorization revoked sooner. Please see the EUA Fact Sheets at www.covid19oralrx.com and www.cvdvaccine-us.com.
This Form 10-K includes discussion of certain clinical studies relating to various in-line products and/or product candidates. These studies typically are part of a larger body of clinical data relating to such products or product candidates, and the discussion herein should be considered in the context of the larger body of data. In addition, clinical trial data are subject to differing interpretations, and, even when we view data as sufficient to support the safety andand/or efficacy of the products we offera product candidate or a new indication for an in-line product, regulatory authorities may not share our views and our research, quality, manufacturing processes, product promotion, advertising and product labeling. Similar regulations exist in most other countries, and in many countries the government also regulates our prices. In the EU, the EMA regulates the scientific evaluation, supervision and safety monitoring of our products, and employs a centralized procedure formay require additional data or may deny approval of drugs for the EU and the European Economic Area countries. In Japan, the PMDA is involved in a wide range of regulatory activities, including clinical studies, approvals, post-marketing reviews and pharmaceutical safety. Health authorities in many middle and lower income countries require marketing approval by a recognized regulatory authority (i.e., similar to the authority of the FDA or EMA) before they begin to conduct their application review process and/or issue their final approval. For additional information, see the Government Regulation and Price Constraints section below.altogether.

ABOUT PFIZER
Pfizer Inc. is a research-based, global biopharmaceutical company. We apply science and our global resources to bring therapies to people that extend and significantly improve their lives through the discovery, development, manufacture, marketing, sale and distribution of biopharmaceutical products worldwide. We work across developed and emerging markets to advance wellness, prevention, treatments and cures that challenge the most feared diseases of our time. We collaborate with healthcare providers, governments and local communities to support and expand access to reliable, affordable healthcare around the world. The Company was incorporated under the laws of the State of Delaware on June 2, 1942.
Most of our revenues come from the manufacture and sale of biopharmaceutical products. We also sell products for the detection of certain illnesses and provide end-to-end R&D services to select innovative biotech companies. We believe that our medicines and vaccines provide significant value for healthcare providers and patients through improved treatment of diseases and improvements in health, wellness and productivity as well as by reducing other healthcare costs, such as emergency room visits or hospitalizations. We seek to enhance the value of our medicines and vaccines and actively engage in dialogues about how we can best work with patients, physicians and payors to prevent and treat disease and improve outcomes. We seek to maximize patient access and evaluate our pricing arrangements and contracting methods with payors to minimize adverse impact on our revenues within the current legal and pricing structures.
We are committed to fulfilling our purpose: Breakthroughs that change patients’ lives. Our purpose fuels everything we do and reflects both our passion for science and our commitment to patients. Our core business principles are:
1.Trust is Everything
2.Science Will Win
3.Disruption Calls for Innovation
4.Time is Life
5.Execution Makes the Difference.
In addition, Pfizer’s ESG strategy, which is integrated into our corporate strategy, focuses on six areas where we see opportunities to create a meaningful impact: product innovation; equitable access and pricing; product quality and safety; diversity, equity and inclusion; climate change; and business ethics.
We manageare committed to strategically capitalizing on growth opportunities, primarily by advancing our own product pipeline and maximizing the value of our existing products, but also through various business development activities. We view our business development activity as an enabler of our strategies and seek to generate growth by pursuing opportunities and transactions that have the potential to strengthen our business and our

capabilities. We assess our business, assets and scientific capabilities/portfolio as part of our regular, ongoing portfolio review process and also continue to consider business development activities that will help advance our business strategy.
On December 14, 2023, we completed our acquisition of Seagen, a global biotechnology company that discovers, develops and commercializes transformative cancer medicines. With the addition of Seagen’s pipeline and its four in-line medicines (Padcev, Adcetris, Tukysa and Tivdak), Pfizer’s oncology portfolio spans multiple modalities, including ADCs, small molecules, bispecifics and other immunotherapies. In addition to the acquisition of Seagen, our significant recent business development activities in 2023 include, among others, the September 2023 divestiture of our early-stage rare disease gene therapy portfolio to Alexion. For a further discussion of our strategy and our business development initiatives, see the Overview of Our Performance, Operating Environment, Strategy and Outlooksection within MD&A and Note 2.
COMMERCIAL OPERATIONS
In 2023, we managed our commercial operations through a global structure consisting of two distinct business segments: Pfizer Innovative Health (IH) and Pfizer Essential Health (EH). The IH and EH operating segments, are each led by a single manager. Eachmanager: Biopharma, our innovative science-based biopharmaceutical business, and Business Innovation, an operating segment has responsibility for itsestablished in the first quarter of 2023 that includes PC1, our contract development and manufacturing organization and a leading supplier of specialty active pharmaceutical ingredients, and Pfizer Ignite, an offering that provides strategic guidance and end-to-end R&D services to select innovative biotech companies that align with our R&D focus areas. In 2023, Biopharma was the only reportable segment. The commercial activitiesstructure within Biopharma included three broad customer groups in 2023: Primary Care, Specialty Care and for certain IPR&D projects for new investigational productsOncology.
At the beginning of 2024, we made changes in our commercial organization to incorporate Seagen and additional indications for in-line products that generally have achieved proof-of-concept. Each business has a geographic footprint across developedimprove focus, speed and emerging markets.

Some additional information aboutexecution. Specifically, within our business segments as ofBiopharma reportable segment we created the date ofPfizer Oncology Division, the filing of this 2017 Form 10-K follows:
Pfizer U.S. Commercial Division, and the Pfizer International Commercial Division:
DivisionDescription
IH focuses on developing and commercializing novel, value-creating medicines and vaccines that significantly improve patients’ lives, as well as products for consumer healthcare.
Key therapeutic areas include internal medicine, vaccines, oncology, inflammation & immunology, rare disease and consumer healthcare.
EH includes legacy brands that have lost or will soon lose market exclusivity in both developed and emerging markets, branded generics, generic sterile injectable products, biosimilars, select branded products including anti-infectives and, through February 2, 2017, HIS. EH also includes an R&D organization, as well as our contract manufacturing business.
We expect that the IH biopharmaceutical portfolio of innovative, largely patent-protected, in-line and newly launched products will be sustained by ongoing investments to develop promising assets and targeted business development in areas of focus to help ensure a pipeline of highly-differentiated product candidates in areas of unmet medical need. The assets managed by IH are science-driven, highly differentiated and generally require a high-level of engagement with healthcare providers and consumers.
EH is expected to generate strong consistent cash flow by providing patients around the world with access to effective, lower-cost, high-value treatments. EH leverages our biologic development, regulatory and manufacturing expertise to seek to advance its biosimilar development portfolio. Additionally, EH leverages capabilities in formulation development and manufacturing expertise to help advance its generic sterile injectables portfolio. EH may also engage in targeted business development to further enable its commercial strategies.

IH will have continued focus on R&D productivity and pipeline strength while maximizing the value of our recently launched brands and in-line portfolio. Our acquisitions of Anacor and Medivation expanded our pipeline in the high priority therapeutic areas of inflammation and immunology and oncology.

For EH, we continue to invest in growth drivers and manage the portfolio to extract additional value while seeking opportunities for operating efficiencies. This strategy includes active management of our portfolio; maximizing growth of core product segments; acquisitions to strengthen core areas of our portfolio further, such as our recent acquisition of AstraZeneca’s small molecule anti-infectives business; and divestitures to increase focus on our core strengths. In line with this strategy, on February 3, 2017, we completed the sale of Pfizer’s global infusion systems net assets, representing the infusion systems net assets that we acquired as part of the Hospira transaction, HIS, to ICU Medical.

Beginning in the first quarter of 2018, revenues for Viagra in the U.S. and Canada, which were reported in IH through December 2017, will be reported in EH (which reported all other Viagra revenues excluding the U.S. and Canada through 2017). Therefore, total Viagra worldwide revenues will be reported in EH from 2018 forward.



Through February 2, 2017,Our R&D Priorities and Strategy. Our R&D priorities include:
delivering a pipeline of highly differentiated medicines and vaccines where we have a unique opportunity to bring the most important new therapies to patients in need;
advancing our EH business segmentcapabilities that can position us for long-term R&D leadership; and
advancing new models for partnerships with creativity, flexibility and urgency to deliver innovation to patients as quickly as possible.
To that end, our R&D primarily focuses on our main therapeutic areas, which are inflammation and immunology, internal medicine, oncology, rare diseases, vaccines, and anti-infectives.
While a significant portion of our R&D is internal, we also included HIS, which includes Medication Management products composed of infusion pumpsseek promising chemical and related softwarebiological lead molecules and services,innovative technologies developed by others to incorporate into our discovery and development processes or projects, as well as intravenous infusionour portfolio. We do so by entering into collaboration, alliance and license agreements with universities, biotechnology companies and other firms as well as through acquisitions and investments. These collaboration, alliance and license agreements and investments allow us to share knowledge, risk and cost. They also enable us to access external scientific and technological expertise, as well as provide us the opportunity to advance our own products and in-licensed or acquired products. For information on certain of these collaborations, alliances and license arrangements and investments, see Note 2.
Our R&D Operations. In 2023, we continued to strengthen our global R&D operations and pursue strategies to improve R&D productivity to achieve a sustainable pipeline that is positioned to deliver value in the near term and over time. Our R&D activity is conducted through various platform functions that support our global operations. Beginning in July 2023, in consideration of planned future investments in oncology, including large volume intravenous solutionsthe December 2023 acquisition of Seagen, we reorganized our R&D platform operations. Discovery to late-phase clinical development for oncology is performed by a new end-to-end Oncology Research and their associated administration sets. On February 3, 2017,Development (ORD) organization and discovery to late-phase clinical development for all remaining therapeutic areas is consolidated into the end-to-end Pfizer Research and Development (PRD) organization. ORD and PRD replace our former WRDM and GPD organizations, where, prior to July 2023, research units within WRDM were generally responsible for research and early-stage development assets and, prior to July 2023, GPD was generally responsible for the clinical development strategy and operational execution of clinical trials for both early- and late-stage clinical assets in Pfizer’s pipeline. In 2023, Biopharma received R&D services from ORD, PRD and the predecessor WRDM and GPD organizations. These services included IPR&D projects for new investigational products and additional indications for in-line products.
We manage R&D operations on a total-company basis through our PRD and ORD organizations described above. Specifically, the Portfolio Management Team, currently led by our Chairman and Chief Executive Officer and composed of other senior executives, is accountable for aligning resources across PRD and ORD, and for helping to ensure optimal capital allocation across the innovative R&D portfolio. We believe that this approach also serves to maximize accountability and flexibility.
We do not disaggregate total R&D expense by development phase or by therapeutic area since, as described above, we completed the saledo not manage all of HISour R&D operations by development phase or by therapeutic area. Further, as we are able to ICU Medical. adjust a significant portion of our spending quickly, we believe that any prior-period information about R&D expense by development phase or by therapeutic area would not necessarily be representative of future spending.
For additional information on our R&D operations, including R&D related costs and expenses, see the NotesCosts and ExpensesResearch and Development Expenses section within MD&A and Note 17.

RESEARCH AND DEVELOPMENT

Our goal is to discover, develop and bring to market innovative products that address major unmet medical needs.
Our R&D Priorities and Strategy

Our R&D priorities include delivering a pipeline of differentiated therapies and vaccines with the greatest medical and commercial potential, advancing our capabilities that can position Pfizer for long-term leadership and creating new models for biomedical collaboration that will expedite the pace of innovation and productivity. To that end, our research and development primarily focuses on:
Biosimilars;
Inflammation and Immunology;
Metabolic Disease and Cardiovascular Risks;
Oncology;
Rare Diseases; and
Vaccines.

In January 2018, we announced our decision to end internal neuroscience discovery and early development efforts and re-allocate funding to other areas where we have stronger scientific leadership. We plan to create a dedicated neuroscience venture fund to support continued efforts to advance the field. The development of tanezumab and potential treatments for rare neuromuscular disorders is not impacted by this decision.

While a significant portion of R&D is done internally, we continue to seek out promising chemical and biological lead molecules and innovative technologies developed by third parties to incorporate into our discovery and development processes or projects, as well as our product lines, by entering into collaborations, alliances and license agreements with other companies, as well as leveraging acquisitions and equity- or debt-based investments. We also enter into agreements pursuant to which a third party agrees to fund a portion of the development costs of one of our pipeline products in exchange for rights to receive potential milestone payments, revenue sharing payments, profit sharing payments and/or royalties. For additional information on these collaborations, agreements and investments, see the Overview of Our Performance, Operating Environment, Strategy and OutlookOur StrategyDescription of Research and Development Operations section in our 2017 Financial Report.

Our R&D Operations

We conduct R&D internally and also through contracts with third parties, through collaborations with universities and biotechnology companies and in cooperation with other pharmaceutical firms. We continue to strengthen our global R&D organization and pursue strategies intended to improve innovation and overall productivity in R&D to achieve a sustainable pipeline that will deliver value in the near term and over time.

Our R&D spending is conducted through a number of matrix organizations. Research Units within our Worldwide Research and Development (WRD) organization are generally responsible for research and early-stage development assets for our IH business (assets that have not yet achieved proof-of-concept). Our science-based and other platform-services organizations, where a significant portion of our R&D spending occurs, provide end-to-end scientific and technical expertise and other services to the various R&D projects, and are organized into science-based functions (which are part of our WRD organization), such as Pharmaceutical Sciences, Medicinal Chemistry, Regulatory and Drug Safety, and non-science-based functions, such as Facilities, Business Technology and Finance. Our R&D organization within the EH business supports the large base of EH products and is expected to develop potential new sterile injectable drugs and therapeutic solutions, as well as biosimilars. Our Global Product Development organization is a unified center for late-stage development for our innovative products and is generally responsible for the operational execution of clinical development of assets that are in clinical trials for our WRD and Innovative portfolios.

For discussion regarding these R&D matrix organizations and additional information on our R&D operations, see the Overview of Our Performance, Operating Environment, Strategy and OutlookOur StrategyDescription of Research and Development Operations and Costs and ExpensesResearch and Development (R&D) Expenses sections in our 2017 Financial Report.

Our R&D Pipeline and Competition

Innovation is critical to the success of our company, and drug discovery and development is time-consuming, expensive and unpredictable. According to the Pharmaceutical Benchmarking Forum, out of 17 compounds entering preclinical development, on average, only one is approved by a regulatory authority in a major market (U.S., the EU or Japan). The process from early discovery or design to development to regulatory approval can take more than ten years. Drug candidates can fail at any stage of the process, and candidates may not receive regulatory approval even after many years of research and development.

As of January 30, 2018, we had the following number of projects in various stages of R&D:
Development of a single compound is often pursued as part of multiple programs. While these drug candidates may or may not eventually receive regulatory approval, new drug candidates entering clinical development phases are the foundation for future products. In addition to discovering and developing new products, our R&D efforts seek to add value to our existing products by improving their effectiveness, enhancing ease of dosing and by discovering potential new indications for them.

Information concerning several of our drug candidates in development, as well as supplemental filings for existing products, is set forth in the Analysis of the Consolidated Statements of Income—Product DevelopmentsBiopharmaceutical section in our 2017 Financial Report, which is incorporated by reference.

Our competitors also devote substantial funds and resources to R&D. We also compete against numerous small biotechnology companies in developing potential drug candidates. The extent to which our competitors are successful in their research could result in erosion of the sales of our existing products and potential sales of products in development, as well as unanticipated product obsolescence. In addition, several of our competitors operate without large R&D expenses and make a regular practice of challenging our product patents before their expiration. For additional information, see the Competition and Item 1A. Risk FactorsCompetitive Products sections below.

Loss of Intellectual Property Rights. The loss, expiration or invalidation of intellectual property rights, patent litigation settlements and judgments and the expiration of co-promotion and licensing rights can have a material adverse effect on our revenues. Once patent protection has expired or has been lost prior to the expiration date as a result of a legal challenge, we typically lose exclusivity on these products, and generic and biosimilar pharmaceutical manufacturers generally produce identical or highly similar products and sell them for a lower price. The date at which generic or biosimilar competition commences may be different from the date that the patent or regulatory exclusivity expires. However, when generic or biosimilar competition does commence, the resulting price competition can substantially decrease our revenues for the impacted products, often in a very short period of time. Also, if one of our product-related patents is found to be invalid by judicial, court or regulatory or administrative proceedings, generic or biosimilar products could be introduced, resulting in the erosion of sales of our existing products. Additionally, we could be subject to claims that our intellectual property rights infringe third party patents.
Certain of our products have experienced patent-based expirations or loss of regulatory exclusivity in certain markets in the last few years, and we expect certain products to face increased generic competition over the next few years. While additional patent expiries will continue, we expect a moderate impact of reduced revenues due to patent expiries from 2024 through 2025. We anticipate a more significant impact of reduced revenues from patent expiries in 2026 through 2030 as several of our in-line products experience patent-based expirations. There is no assurance that a particular product will maintain market exclusivity for the full time period that appears in the estimates included in this Form 10-K or that we assume when we provide our financial guidance.

The expiration of a basic product patent or loss of patent protection resulting from a legal challenge normally results in significant competition from generic products against the originally patented product and can result in a significant reduction in revenues for that product in a very short period of time. In some cases, however, we can continue to obtain commercial benefits from product manufacturing trade secrets; patents on uses for products; patents on processes and intermediates for the economical manufacture of the active ingredients; patents for special formulations of the product or delivery mechanisms; or conversion of the active ingredient to OTC products.

Biotechnology Products

Our biotechnology products, including BeneFIX, ReFacto, Xyntha, Bavencio, Prevnar 13/Prevenar 13 and Enbrel (we market Enbrel outside the U.S. and Canada), may face in the future, or already face, competition from biosimilars (also referred to as follow-on biologics). In the U.S., such biosimilars would reference biotechnology products approved under the U.S. Public Health Service Act. Additionally, the FDA has approved a follow-on recombinant human growth hormone that referenced our biotechnology product, Genotropin, which was approved under the FFDCA.

Biosimilars are versions of biologic medicines that have been developed and proven to be similar to the original biologic in terms of safety and efficacy and to have no clinically meaningful differences. Biosimilars have the potential to offer high-quality, lower-cost alternatives to biologic medicines. Abbreviated legal pathways for the approval of biosimilars exist in certain international markets and, since the passage in 2010 of the ACA, a framework for such approval exists in the U.S.

In Europe, the European Commission has granted marketing authorizations for several biosimilars pursuant to a set of general and product class-specific guidelines for biosimilar approvals issued over the past few years.

As part of our business strategy, we are capitalizing on our expertise in biologics manufacturing, as well as our regulatory and commercial strengths, to develop biosimilar medicines. See Item 1A. Risk FactorsBiotechnology Products below.

We may face litigation with respect to the validity and/or scope of patents relating to our biotechnology products. Likewise, as we develop and manufacture biosimilars and seek to launch products, patents may be asserted against us.

COMPETITION

Our businesses arebusiness is conducted in intensely competitive and often highly regulated markets. Many of our prescription pharmaceutical products face competition in the form of branded or generic drugs or biosimilars that treat similar diseases or indications. The principal forms of competition include efficacy, safety, ease of use and cost effectiveness.cost. Though the means of competition vary among product categories and business groups,our products, demonstrating the value of our products is a critical factor for success in all ofsuccess.
We compete with other companies that manufacture and sell products that treat or prevent diseases or indications similar to those treated or prevented by our principal businesses.

Ourmajor products. These competitors include other worldwide research-based biopharmaceutical companies, smaller research companies with more limited therapeutic focus and generic drug and biosimilar drug manufacturersmanufacturers. Our competitors also may devote substantial funds and consumer healthcare manufacturers. We compete with other companies that manufactureresources to R&D and selltheir successful R&D could result in erosion of the sales of our existing products that treat diseases or indications similar to those treated byand potential sales of our major products.products in development, as well as product obsolescence. In addition, several of our competitors operate without large R&D expenses and make a regular practice of challenging our product patents before their expiration.

This competition affects our core product business,To help address competitive trends we continually emphasize innovation, which is focused on applying innovative science to discover and market products that satisfy unmet medical needs and provide therapeutic improvements. Our emphasis on innovation is underscored by our multi-billion-dollar investment in R&D, as well as our business development transactions, both designed to result in a strong and differentiated product pipeline.

enhance the organizational effectiveness of all of our biopharmaceutical functions, including coordinating support for our salespersons’ efforts to accurately and ethicallyeffectively launch and promotemarket our products to our customers.

Operating conditions have become more challenging under mountingalso shifted as a result of increased global competitive pressures, of competition, industry regulation and cost containment. We continue to take measures to evaluate, adapt and improve our organization and business practices in an effort to better meet customer and public needs. We believe that we have taken an industry-leading role in evolving our ethical approaches to U.S. direct-to-consumer advertising;advertising, interactions with, and payments to, healthcare professionals;professionals and medical education grants. We also continue to sponsorsupport programs to address patient affordability and access barriers, as we strive to advance fundamental health system change through our support for better healthcare solutions. For example, in May 2022, we launched An Accord for a Healthier World, which aims to provide our full portfolio of patented and off-patent medicines and vaccines for which Pfizer holds global rights on a not-for-profit basis to 1.2 billion people living in 45 lower-income countries around the world.

Our vaccines businesshave and may continue to face competition, including from the introduction of alternative vaccines or next generation vaccines. For example, Prevnar 13 may face competition in the form of alternative 13-valent or additional valent next-generation pneumococcal conjugate“next-generation” vaccines prior to or after the expiration of itstheir patents, which may adversely affect our future results.

Our genericsbiosimilars, which include biosimilars of certain inflammation & immunology and biosimilars businessesoncology biologic medicines, compete with branded products from competitors, as well as other generics and biosimilars manufacturers. Globally, Pfizer sells generic versions of Pfizer’s, as well as certain competitors’, solid oral dose and sterile injectable pharmaceutical products, as well as biosimilars. We seek to maximize the opportunity to establish a “first-to-market” or early market position for our generic injectable drugs and biosimilars as a “first-to-market” position providesto provide customers a lower-cost alternative immediately when available and also mayto potentially provide us with potentially higher levels of sales and profitability until other generic or biosimilar competitors enter the market.

Our Consumer Healthcare business faces competition from OTC business units in other majorGeneric Products. Generic pharmaceutical and consumer packaged goods companies, and retailers who carry their own private label brands. Our competitive position is affected by several factors, including the amount and effectiveness of our and our competitors’ promotional resources; customer acceptance; product quality; our and our competitors’ introduction of new products, ingredients, claims, dosage forms, or other forms of innovation; and pricing, regulatory and legislative matters (such as product labeling, patient access and prescription to OTC switches).

Managed Care Organizations

The evolution of managed care in the U.S. has been a major factor in the competitive makeup of the healthcare marketplace. Approximately 291 million people in the U.S. now have some form of health insurance coverage. Due to the expansion of health insurance coverage (see Government Regulation and Price ConstraintsIn the United States below), the marketing of prescription drugs to both consumers and the entities that manage this expanded coverage in the U.S. continues to grow in importance.

The influence of MCOs has increased in recent years due to the growing number of patients receiving coverage through MCOs. At the same time, those organizations have been consolidating into fewer, even larger entities. This consolidation enhances both their ability to negotiate, as well as their importance to Pfizer.

The growth of MCOs has increased pressure on drug prices as well as revenues. One objective of MCOs is to contain and, where possible, reduce healthcare expenditures. MCOs typically negotiate prices with pharmaceutical providers by using formularies (which are lists of approved medicines available to members of the MCOs), clinical protocols (requiring prior authorization for a branded product if a generic product is available or requiring the patient to first fail onmanufacturers pose one or more generic products before permitting access to a branded medicine), volume purchasing, long-term contracts and their ability to influence volume and market share of prescription drugs. In addition, by placing branded medicines on higher-tier status in their formularies (leading to higher patient co-pays) or non-preferred tier status, MCOs transfer a portion of the cost of the medicine to the patient, resulting in significant out-of-pocket expenses for the patient, especially for chronic treatments. This financial disincentive is a tool for MCOs to manage drug costs and channel patients to medicines preferred by the MCOs. MCOs also use additional measures such as new-to-market blocks, exclusion lists, indication-based pricing, copay accumulator programs and value-based pricing/contracting to improve their cost containment efforts. We are closely monitoring these newer approaches and developing appropriate strategies to respond to them.

Due to their generally lower cost, generic medicines typically are placed in lowest cost tiers of MCO formularies. The breadth of the products covered by formularies can vary considerably from one MCO to another, and many formularies include alternative and competitive products for treatment of particular medical problems. MCOs are currently evaluating the appropriate placement of biosimilars on their formularies.

Exclusion of a product from a formulary or other MCO-implemented restrictions can significantly impact drug usage in the MCO patient population. Consequently, pharmaceutical companies compete to gain access to formularies for their products. Unique product features, such as greater efficacy, better patient ease of use, or fewer side effects, are generally beneficial to achieving access to formularies. However, lower overall cost of therapy is also an important factor. We have been generally, although not universally, successful in having our major products included on MCO formularies. However, increasingly our branded products are being placed on the higher tiers or in a non-preferred status.


Pfizer Inc.2017 Form 10-K7

TABLE OF CONTENTS

MCOs also emphasize primary and preventive care, out-patient treatment and procedures performed at doctors’ offices and clinics as another way to manage costs. Hospitalization and surgery, typically the most expensive forms of treatment, are carefully managed. Since the use of certain drugs can reduce the need for hospitalization, professional therapy, or even surgery, such drugs can become favored first-line treatments for certain diseases.

The ACA has accelerated payment reform by distributing risk across MCOs and other stakeholders in care delivery with the intent of improving quality while reducing costs, which creates pressure on MCOs to tie reimbursement to defined outcomes. Under the Trump administration, there have been ongoing efforts to modify or repeal all or certain provisions of the ACA, although the current likelihood of repeal of the ACA appears low given the failure of the Senate’s multiple attempts to repeal various combinations of ACA provisions. We are monitoring any such actions to see if any changes to the ACA will be enacted that would impact our business.

Generic Products

One of the biggest competitive challenges thatto our branded small molecule products face is from generic pharmaceutical manufacturers. Uponbecause they can market a competing version of our product after the expiration or loss of our patent protection for a product, especially a small molecule product, we can lose the major portion of revenues for that product in a very short period of time.and often charge much less. Several competitors make a regular practice of challengingregularly challenge our product patents before their expiration. Generic competitors often operate without large R&D expenses, as well as without costs of conveying medical information about products to the medical community. In addition, the FDA approval process in the U.S. and in the EU exempts generics from costly and time-consuming clinical trials to demonstrate their safety and efficacy, allowing generic manufacturers to rely on the safety and efficacy data of the innovator product. Generic competitors do not generally needIn China, for example, given the expansion of the QCE process and continuation of the VBP program, we expect to conduct clinical trialscontinue to face intensified competition by certain generic manufacturers in 2024 and can market a competing versionbeyond, which has and may continue to result in price cuts and volume loss of some of our product after the expiration or loss of our patent and often charge much less.

As noted above, MCOs that focus primarily on the immediate cost of drugs often favor generics over brand-name drugs. Many governments alsoCommercial and government payors typically encourage the use of generics as alternatives to brand-name drugs in their healthcare programs, including Medicaid in the U.S. Laws in the, and U.S. laws generally allow, and in some cases require, pharmacists to substitute for brand-name drugs, generic drugs that have been rated under government procedures to be chemically and therapeutically equivalent tofor brand-name drugs. In a small subset of states, prescribing physicians are able to expressly prevent such substitution. Similar rules also apply in several EU member states, where national authorities typically encourage and incentivize the use of generic products.
RAW MATERIALS

Raw materials essential toBiosimilars. Certain of our businesses are purchased worldwidebiologic products, including Enbrel (we market Enbrel outside the U.S. and Canada), already face, or may face in the ordinary course
future, competition from biosimilars (also referred to as follow-on biologics). Biosimilars are versions of business from numerous suppliers. In general, these materials are available from multiple sources. In 2017, we experienced periodic shortages of select materials due to constrained capacity or operational challenges with the associated suppliers. Supplier management activities are ongoing to work to ensure the necessary supply to meet our requirements for these materials. No significant impact to our operations is anticipated in 2018.
GOVERNMENT REGULATION AND PRICE CONSTRAINTS

Pharmaceutical companies are subject to extensive regulation by government authorities in the countries in which they do business. Certain lawsbiologic medicines that have been developed and regulations that govern Pfizer’s business are discussed below.

Failureefficacy and that have no clinically meaningful differences in safety, purity or potency. Biosimilars have the potential to comply with these laws and regulations, including those governing the manufacture and marketing of our products, could subject usoffer high-quality, lower-cost alternatives to administrative and legal proceedings and actions by various governmental bodies. For additional information on these proceedings and actions, see the Notes to Consolidated Financial Statements—Note 17A. Commitments and Contingencies—Legal Proceedings in our 2017 Financial Report. Criminal charges, substantial fines and/or civil penalties, warning letters and product recalls or seizures, delays in product approvals, as well as limitations on our ability to conduct business in applicable jurisdictions, could result from such proceedings and actions.

In the United States

Drug Regulation.innovative biologic medicines. In the U.S., biopharmaceuticalbiosimilars referencing innovative biologic products are subject to extensive pre- and post-market regulationsapproved by the FDA including regulations that govern the testing, manufacturing, safety, efficacy, labeling and storage of our products, record keeping, advertising and promotion. Our products are also subject to post-market surveillance under the FFDCA and its implementing regulations with respect to drugs, as well as theU.S. Public Health Service Act, whereas in the EU the EMA is responsible for evaluating the majority of applications for biosimilars through the centralized procedure.
PRICING PRESSURES AND MANAGED CARE ORGANIZATIONS
Commercial Pricing Pressures. Pricing and its implementing regulations with respectaccess pressures in the commercial sector continue to biologics. The FDA also regulatesbe significant. Overall, there is increasing pressure on U.S. providers to deliver healthcare at a lower cost and to ensure that those expenditures deliver demonstrated value in terms of health outcomes. Many employers have adopted or make available high deductible health plans, which can increase out-of-pocket costs for medicines. This trend is likely to continue. Private third-party payors, such as health plans, increasingly challenge pharmaceutical product pricing, which could result in lower prices, lower reimbursement rates for payors and a reduction in demand for our Consumer Healthcare products.

Other U.S. federal agencies, including the DEA, also regulate certain of our products. The U.S. Federal Trade Commission has the authority to regulate the advertising of consumer healthcare products, including OTC drugs and dietary supplements. Manydenial of our activities also are subject to the jurisdiction of the SEC.

Before a new biopharmaceutical product may be marketed in the U.S., the FDA must approve an NDA for a new drug or a BLA for a biologic. The steps required before the FDA will approve an NDA or BLA generally include preclinical studies followed by multiple stages of clinical trials conducted by the study sponsor; sponsor submission of the application to the FDA for review; the FDA’s review of the data to assess the drug’s safety and effectiveness; and the FDA’s inspection of the facilities where the product will be manufactured.

Before a generic drug may be marketed in the U.S., the FDA must approve an ANDA. The ANDA review process typically does not require new preclinical and clinical studies, because it relies on the studies establishing safety and efficacy conducted for the referenced drug previously approved through the NDA process. The ANDA process, however, does require the sponsor to conduct one or more bioequivalence studies to show that the ANDA drug is bioequivalent to the previously approved referenced brand drug, submission of an application to the FDA for review, and the FDA’s inspection of the facilities where the product will be manufactured.

As a condition of product approval, the FDA may require a sponsor to conduct post-marketing clinical studies, known as Phase 4 studies, and surveillance programs to monitor the effect of the approved product. The FDA may limit further marketing of a product based on the results of these post-market studies and programs. Any modifications to a drug or biologic, including new indications or changes to labeling or manufacturing processes or facilities, may require the submission and approval of a new or supplemental NDA or BLA before the modification can be implemented, which may require that we develop additional data or conduct additional preclinical studies and clinical trials. Our ongoing manufacture and distribution of drugs and biologics is subject to continuing regulation by the FDA, including recordkeeping requirements, reporting of adverse experiences associated with the product, and adherence to cGMPs, which regulate all aspects of the manufacturing process. We are also subject to numerous regulatory requirements relating to the advertising and promotion of drugs and biologics, including, but not limited to, standards and regulations for direct-to-consumer advertising. Failure to comply with the applicable regulatory requirements governing the manufacture and marketingcoverage of our products, if lower cost alternatives are available. Payors often require significant discounts, or rebates, from our prices in exchange for more favorable formulary placement. Pricing pressures also may subject usoccur as a result of highly competitive biopharmaceutical markets and increasing concentration of insurers and PBMs. Healthcare provider purchasers, directly or through group purchasing organizations, are seeking enhanced discounts or implementing more rigorous bidding or purchasing review processes.
Longer term, we foresee a shift in focus among payors and their PBMs away from fee-for-service reimbursement towards outcomes-based payments and risk-sharing arrangements that reward providers and pharmaceutical manufacturers for cost reductions and improved patient outcomes. These new payment models can, at times, lead to administrativelower prices for, and restricted access to, new medicines. At the same time, these models can also promote utilization of drugs by encouraging physicians to screen and diagnose and consider drugs as a means of forestalling more costly medical interventions. Further, these models may also encourage payors and their PBMs to cover higher cost drugs where coverage is tied to patient outcomes and other quality incentives.

Pfizer Inc.2023 Form 10-K10


The impact of large-scale healthcare disruptions, like the COVID-19 pandemic, on the pace of adoption of value-based payment models remains unclear. Both payors and providers may resist adopting such models or judicial sanctions, including warning letters, product recalls or seizures, delayschoose to adopt such models at a slower pace if the incentives available do not outweigh the financial risk involved. Adoption of such models, in product approvals, injunctions, fines, civil penalties and/or criminal prosecution.

Biosimilar Regulation. The ACA created a frameworkparticular models that involve downside risk, may depend on revenue predictability for the approvalhospitals and other institutional providers, many of biosimilars (also known as follow-on biologics)which are still struggling to recover financially following the expirationCOVID-19 pandemic. Providers in more advanced value-based payment models, such as full capitation, a fixed amount paid in advance per-patient per-unit of 12 yearstime-period, generally found their revenues remained steady during the COVID-19 pandemic, which may ultimately encourage the growth of exclusivity for the innovator biologic, with a potential six-month pediatric extension. Under the ACA, biosimilar applications may not be submitted until four years after the approval of the reference, innovator biologic.

The FDA is responsible for implementation of the legislationsuch models. Going forward, we expect continued focus on value-based payment models that support financial resiliency and approval of new biosimilars. Through those approvals and the issuance of draft and final guidance, the FDA has begun to address open questions about the naming convention for biosimilars and the use of data from a non-U.S.-licensed comparator to demonstrate biosimilarity and/or interchangeability with a U.S.-licensed reference product. Over the next several years, the FDA is expected to issue additional draft and final guidance documents impacting biosimilars. In addition, in 2017, the Biosimilar User Fee Act was reauthorized for a five-year period, which should lead to a significant increase in the FDA’s biosimilar user fee revenues, thereby providing the FDA with additional resources to process biosimilar applications. Also, there have been ongoing federal legislative and administrative efforts to repeal, substantially modify or invalidate some or all of the provisions of the ACA. While none of those efforts have focused on changes to the provisions of the ACA related to the biosimilar regulatory framework, if those efforts continue in 2018 and if the ACA is repealed, substantially modified, or invalidated, it is unclear what, if any, impact such action would have on biosimilar regulation.

Sales and Marketing. The marketing practices of U.S. biopharmaceutical companies are generally subject to various federal and stateadvance healthcare laws that areequity by incorporating features intended to prevent fraudreduce disparities in healthcare quality and abuse in the healthcare industryaccess experienced by underrepresented and protect the integrity of government healthcare programs. These laws include anti-kickback laws and false claims laws. Anti-kickback laws generally prohibit a biopharmaceutical company from soliciting, offering, receiving, or paying any remuneration to generate business, including the purchase or prescription of a particular product. False claims laws generally prohibit anyone from knowingly and willingly presenting, or causing to be presented, any claims for payment for goods (including drugs) or services to third-party payers (including Medicare and Medicaid) that are false or fraudulent and generally treat claims generated through kickbacks as false or fraudulent. Violations of fraud and abuse laws may be punishable by criminal or civil sanctions and/or exclusion from federal healthcare programs (including Medicare and Medicaid). The federal government and various states also have enacted laws to regulate the sales and marketing practices of pharmaceutical companies. The laws and regulations generally limit financial interactions between manufacturers and healthcare providers; require disclosure to the federal or state government and public of such interactions; and/or require the adoption of compliance standards or programs. Many of these laws and regulations contain ambiguous requirements or require administrative guidance for implementation. Individual states, acting through their attorneys general, have become active as well, seeking to regulate the marketing of prescription drugs under state consumer protection and false advertising laws. Given the lack of clarity in laws and their implementation, our activities could be subject to the penalties under the pertinent laws and regulations.underserved populations.

Pricing and Reimbursement. Pricing for our pharmaceutical products depends in part on government regulation. Pfizer must offer discounted pricing or rebates on purchases of pharmaceutical products under various federal and state healthcare programs, such as the Medicaid Drug Rebate Program, the “federal ceiling price” drug pricing program, the 340B drug pricing program and the Medicare Part D Program. Pfizer must also report specific prices to government agencies under healthcare programs, such as the Medicaid Drug Rebate Program and Medicare Part B. The calculations necessary to determine the prices reported are complex and the failure to report prices accurately may expose Pfizer to penalties. See the discussion regarding rebates in the Analysis of the Consolidated Statements of IncomeRevenuesOverview section in our 2017 Financial Report and in the Notes to Consolidated Financial Statements—Note 1G. Basis of Presentation and Significant Accounting Policies: Revenues and Trade Accounts Receivable in our 2017 Financial Report, which are incorporated by reference.

Government and private third-party payers routinely seek to manage utilization and control the costs of our products. For example, the majority of states use preferred drug lists to restrict access to certain pharmaceutical products under Medicaid. Restrictions exist for some Pfizer products in certain states. As another example, access to our products under the Medicaid managed care program is typically determined by the health plans with which state Medicaid agencies contract to provide services to Medicaid beneficiaries. Given certain states’ current and potential ongoing fiscal crises, a growing number of states are considering a variety of cost-control strategies, including capitated managed care plans that typically contain cost by restricting access to certain treatments. In addition, we expect that consolidation and integration of pharmacy chains and wholesalers, who are the primary purchasers of our pharmaceutical products in the U.S., will increase competitive and pricing pressures on pharmaceutical manufacturers, including us.

Efforts by government officials or legislators to implement measures to regulate prices or payment for pharmaceutical products, including legislation on drug importation, could adversely affect our business if implemented. Recently, there has been considerable public and government scrutiny of pharmaceutical pricing and proposals to address the perceived high cost of pharmaceuticals. There have also been recent state legislative efforts to address drug costs, which generally have focused on increasing transparency around drug costs or limiting drug prices. Recent legislation enacted includes, for example, a 2017 Maryland law that prohibits a generic drug manufacturer or wholesale distributor from engaging in price gouging in the sale of certain off-patent or generic drugs, and a 2017 California law that requires manufacturers to provide advanced notification of price increases to certain purchasers and report specified drug pricing information to the state.Certain state legislation, like the Maryland law, has been subject to legal challenges.

Adoption of new legislation at the federal or state level could further affect demand for, or pricing of, our products. We believe medicines and vaccines are the most efficient and effective use of healthcare dollars based on the value they deliver to the overall healthcare system. We will continue to work with law makers and advocate for solutions that effectively improve patient health outcomes, lower costs to the healthcare system, and help ensure access to medicines and vaccines within an efficient and affordable healthcare system.

Healthcare Reform. The This includes assessing our go-to market model to help address patient affordability challenges. We have engaged with major payors and the U.S. government to explore opportunities to improve access and reimbursement in an effort to drive pro-patient policies. In addition, in response to the evolving U.S. and state governmentsglobal healthcare spending landscape, we work with health authorities, health technology assessment and quality measurement bodies and major U.S. payors throughout the product-development process to better understand how these entities value our compounds and products. Further, we are developing stronger support designed to demonstrate the net value of the medicines and vaccines that we discover or develop, register and manufacture.
For information on government pricing pressures, see the Item 1. BusinessGovernment Regulation and Price Constraints and Item 1A. Risk FactorsPricing and Reimbursementsections.
Managed Care Organizations. The evolution of managed care in the U.S. has been a major factor in the competitiveness of the healthcare marketplace. Approximately 318 million people in the U.S. now have some form of health insurance coverage, and the marketing of prescription drugs and vaccines to both consumers and the entities that manage coverage in the U.S. continues to grow in importance. In particular, the influence of MCOs has increased in recent years due to the growing number of patients receiving coverage through MCOs. At the same time, consolidation in the MCO industry has resulted in fewer, even larger MCOs, which enhances those MCOs’ ability to negotiate lower pricing and further increases their importance to our business. Since MCOs seek to contain and reduce healthcare expenditures, their growing influence has increased downward pressure on drug prices, as well as negatively impacted revenues.
MCOs and their PBMs typically negotiate prices with pharmaceutical providers by using formularies (which are lists of approved medicines available to MCO members), clinical protocols (which require prior authorization for a branded product if a generic product is available or require the patient to first fail on one or more generic products before permitting access to a branded medicine), long-term contracts and their ability to influence volume and market share of prescription drugs. In addition, by placing branded medicines on higher-tier or non-preferred status in their formularies, MCOs transfer to the patient higher patient out-of-pocket expenses. This financial disincentive is a tool for MCOs to manage drug costs and channel patients to medicines preferred by the MCOs. We expect payment reforms for MCOs will continue to proposeevolve with increased emphasis on expanded participation and pass legislation designedon removing barriers to equitable healthcare.
The breadth of the products covered by formularies can vary considerably from one MCO to another, and many formularies include alternative and competitive products for treatment of particular medical problems. MCOs emphasize primary and preventive care, out-patient treatment and procedures performed at doctors’ offices and clinics as ways to manage costs. Hospitalization and surgery, typically the most expensive forms of treatment, are carefully managed, and drugs that can help in chronic care management and reduce the need for hospitalization, professional therapy or surgery may become favored first-line treatments for certain diseases. At the same time, MCOs may seek to exclude high-cost drugs from formularies in their efforts to manage and lower their costs.
Exclusion of a product from a formulary or other MCO-implemented restrictions can significantly impact drug usage in the MCO patient population and beyond. Consequently, pharmaceutical companies compete to gain access to formularies for their products, typically on the basis of unique product features, such as greater efficacy, better patient ease of use, or fewer side effects, as well as the overall cost of the therapy. We continue to seek to ensure that our major products are included on MCO formularies. However, our branded products are increasingly being placed on the higher tiers or in a non-preferred status. Continuing efforts by managed care entities to contain or reduce costs of healthcare and/or impose price controls may adversely affect demand for our products and our financial performance. See the Item 1A. Risk FactorsManaged Care Trends section.
RAW MATERIALS
We procure raw materials essential to our business from numerous suppliers worldwide. In general, these materials have been available in sufficient quantities to support our demand and in many cases are available from multiple suppliers. No significant impact to our operations due to the availability of raw materials is currently anticipated in 2024. However, we continue to see heightened demand in the industry for certain components and raw materials, which could potentially result in constraining available supply leading to a possible future impact on our business. We are continuing to monitor and implement mitigation strategies to reduce any potential risk or impact including active supplier management, qualification of additional suppliers and advanced purchasing to the extent possible.
GOVERNMENT REGULATION AND PRICE CONSTRAINTS
We are subject to extensive regulation by government authorities in the countries in which we do business. This includes laws and regulations governing the operations of biopharmaceutical companies, such as the approval, manufacturing and marketing of products, pricing (including discounts and rebates) and price reporting, interactions with healthcare professionals, institutions, and referral sources, reporting of remuneration provided to healthcare providers and academic medical centers, financial assistance provided to patients, clinical research, data privacy and information security, among others. These laws and regulations may require administrative guidance for implementation, and a failure to comply could subject us to legal and/or administrative actions. Enforcement measures may include substantial fines and/or penalties, orders to stop non-compliant activities, criminal charges, warning letters, product recalls or seizures, delays in product approvals, exclusion from participation in government programs or contracts as well as limitations on conducting business in applicable jurisdictions, and could result in harm to our reputation and business. See Note 16A. Compliance with these laws and regulations may be costly, and may require significant technical expertise and capital investment to ensure compliance. While capital expenditures or operating costs for compliance with government regulations

Pfizer Inc.2023 Form 10-K11


cannot be predicted with certainty, we do not currently anticipate they will have a material effect on our capital expenditures or competitive position.
In the U.S.
Drug and Biologic Regulation. The FDA, pursuant to the FFDCA, the Public Health Service Act and other federal statutes and regulations, extensively regulates pre- and post-marketing activities related to our biopharmaceutical products and devices. The regulations govern areas such as safety and efficacy, clinical trials, advertising and promotion, quality control, manufacturing, labeling, distribution, post-marketing safety surveillance and reporting, and record keeping. Other U.S. federal agencies, including the DEA, also regulate certain of our products and activities.
For a biopharmaceutical company to market a drug or a biologic product, including vaccines, the FDA must evaluate whether the product is safe and effective for its intended use. If the FDA determines that the drug or biologic is safe and effective, the FDA will approve the product’s NDA or BLA (or supplemental NDA or supplemental BLA), as appropriate.
A drug or biologic may be subject to postmarketing commitments, which are studies or clinical trials that the product sponsor agrees to conduct, or postmarketing requirements, which are studies or clinical trials that are required as a condition of approval. In addition, we are also required to report adverse events and comply with cGMPs (the FDA regulations that govern all aspects of manufacturing quality for pharmaceuticals) and the Drug Supply Chain Security Act (the law that, among other things, sets forth requirements related to product tracing, product identifiers and verification for manufacturers, wholesale distributors, re-packagers and dispensers to facilitate the tracing of product through the pharmaceutical distribution supply chain), as well as advertising and promotion regulations. See the Item 1A. Risk FactorsDevelopment, Regulatory Approval and Marketing of ProductsandPost-Authorization/Approval Datasections.
In the context of public health emergencies, like the COVID-19 pandemic, we may apply to the FDA for an EUA which, if granted, allows for the distribution and use of our products during the declared emergency, in accordance with the conditions set forth in the EUA, unless the EUA is terminated by the government. Although the criteria for an EUA differ from the criteria for approval of an NDA or BLA, EUAs nevertheless require the development and submission of data to satisfy the relevant FDA standards, and a number of ongoing obligations. The FDA generally expects EUA holders to work toward submission of full applications, such as a BLA or an NDA, as soon as possible.
Biosimilar Regulation. The FDA is responsible for approval of biosimilars. Innovator biologics, or reference products, are entitled to 12 years exclusivity. Applications for biosimilars may not be submitted until four years after the date on which the reference product was first licensed and may not be approved until 12 years after the reference product was first licensed.
Sales and Marketing Regulations. Our marketing practices are subject to federal and state laws, such as the Anti-Kickback Statute (AKS), Civil Monetary Penalties Law and False Claims Act, intended to prevent fraud and abuse in the healthcare industry. The AKS prohibits soliciting, offering, receiving, or paying anything of value to generate business that may be paid for, in whole or in part, by a federal healthcare program. The Civil Monetary Penalties Law covers a variety of conduct, often violations under other laws, and includes penalties for AKS violations as well as causing the submission of false claims. The False Claims Act generally prohibits anyone from knowingly and willingly presenting, or causing to be presented, any claims for payment for goods or services, including to government payors, such as Medicare and Medicaid, that are false or fraudulent including false certifications of compliance with applicable law. The federal government and states also regulate sales and marketing activities and financial interactions between manufacturers and healthcare providers, requiring disclosure to government authorities and the public of such interactions, and the adoption of compliance standards or programs. State attorneys general have also taken action to regulate the marketing of prescription drugs under state consumer protection and false advertising laws.
Pricing, Reimbursement and Access Regulations. Pricing and reimbursement for our products depend in part on government regulation. Any significant efforts at the federal or state levels to reform the healthcare industry. For example, in March 2010,system by changing the U.S. Congress enactedway healthcare is provided or funded or to expand controls on drug pricing, government reimbursement, and access to medicines and vaccines on public and private insurance plans could have a material impact on us.
We must offer discounts or rebates on purchases of pharmaceutical products under various government programs including Medicare, Medicaid, the ACA that expanded healthcare coverage through Medicaid expansionVeterans Administration and the implementation of340B Drug Pricing Program (340B Program). We also must report specific prices to government agencies. The calculations necessary to determine the individual health insurance exchangesprices reported are complex and which included changesthe failure to do so accurately may expose us to enforcement measures. See the coveragediscussion regarding rebates in theProduct Revenue Deductionssection within MD&A and reimbursement ofNote 1G.
The drug products under government healthcare programs.

Under President Trump’s administration, there have been ongoing efforts to modify or repeal all or certainpricing provisions of the ACA, although the current likelihood of repeal of the ACA appears low given the failure of the Senate’s multiple attempts to repeal various combinations of ACA provisions. In October 2017, the President signed an Executive Order directing federal agencies to look for ways to authorize more health plans that could be less expensive because the plans would not have to meet all of the ACA’s coverage requirements, and announced that his administration will withhold the cost-sharing subsidies paid to health insurance exchange plans serving low-income enrollees. In December 2017, the comprehensive tax reform packageIRA, which was signed into law in August 2022, began to be implemented in 2022 and implementation will continue over the Tax Cutsnext several years. The IRA includes several provisions to lower prescription drug costs for Medicare patients and Jobs Act, includes a provision that effectively repealed the ACA’s individual mandate by removing the penalties. These and similar actionsto reduce drug spending by the administrationfederal government. Among other things, the IRA enhances the Medicare Part D benefit by eliminating the coverage gap (“donut hole”) beginning in 2025, adds a maximum out-of-pocket cap for Medicare beneficiaries (set at $2,000 for 2025), and creates a new program that allows patients to pay their cost-sharing over time. The law also requires manufacturers to provide a 10% discount on branded prescriptions in the initial coverage phase and a 20% discount in the catastrophic phase, imposes rebates under Medicare Part B and Medicare Part D on drug price increases that outpace inflation, and directs HHS to set the prices of certain high-expenditure, single-source drugs and biologics covered under Medicare (known as the “Medicare Drug Price Negotiation Program”). In August 2023, the Biden Administration published the first ten medicines subject to the Medicare Drug Price Negotiation Program, which included Eliquis. As a selected drug, CMS will establish a “maximum fair price” for Eliquis and that price will be published by September 1, 2024. The price will be in effect in 2026. The maximum fair price established by CMS is required to be offered to all Medicare beneficiaries and to covered entities participating in the 340B Program if that maximum fair price is lower than the discounted price such entities are widelyoffered under the 340B Program ceiling price calculation. In addition, there will be a new Medicare manufacturer discount program agreement expected to leadbe signed in March 2024 that will change our discounting obligations for all medicines in Medicare, with few exceptions, beginning in 2025. The Medicare Drug Price Negotiation Program is currently subject to fewer Americans having comprehensive ACA-compliant health insurance, even inlegal challenges and therefore, the absenceoutcome of a full legislative repeal. The revenues generated for Pfizer by the health insurance exchanges under the ACA are minor, soProgram remains uncertain. We continue to evaluate the impact of the recent administration actions is expected to be limited. We also may face uncertainties ifIRA on our industry is looked to for savings to fund certain legislation, suchbusiness, operations and financial condition and results as lifting the debt ceiling. One recent example is the Bipartisan Budget Act of 2018, which increased the discount we pay in the Medicare Part D coverage gap from 50% to 70%, which will modestly reduce our future Medicare Part D revenues.

We cannot predict the ultimate content, timing orfull effect of anythe IRA on our business and the pharmaceutical industry remains uncertain.
Changes to the Medicaid Drug Rebate Program or the 340B Program could have a material impact on our business. For example, certain changes finalized by CMS in a December 2020 final rule, including which products qualify as so-called “line extension” drugs subject to increased rebate liability, may have a material impact on our business. Additionally, in May 2023, CMS proposed new rules that could, if finalized, have a material impact on our business. Those proposals include, for example, new rules regarding how manufacturers would be required to aggregate discounts for purposes of determining their Medicaid Best Price. Additionally, various potential changes to the ACA340B Program are undergoing

review or are the subject of current regulatory activity and/or litigation, and their status is unclear. In 2022, we implemented a policy that will help improve contract pharmacy integrity. The HHS Health Resources and Services Administration (HRSA), which administers the 340B Program, has sent letters to numerous manufacturers that have also implemented contract pharmacy policies and integrity initiatives; the letters express HRSA’s view that those manufacturers’ policies are in violation of the 340B statute. HRSA also has referred some of those other manufacturers to the HHS Office of Inspector General (OIG) for potential enforcement action. Pfizer has not received an enforcement letter from HRSA to date relating to our 340B Program integrity initiative. Several manufacturers have challenged HRSA’s enforcement letters in federal court and litigation is ongoing in those cases. We believe that our policy is consistent with the statute. In addition, some states have enacted laws seeking to restrict manufacturer policies related to contract pharmacy transactions in their states. At least one state reform efforts. There is no assurance thathas begun to pursue enforcement proceedings under its law. Several stakeholders have challenged such laws in certain states. Other states have considered and could enact similar laws going forward, although any such laws also may be subject to legal challenges. Additional legal or legislative developments at the federal or state level with respect to the 340B Program may have an adverse impact on our integrity initiative, and we may face enforcement action or penalties, depending upon such developments. The 340B Program continues to be a subject of regulatory activity, congressional scrutiny and inquiries, litigation, and other developments, any or all of which could affect the scope of the program and Pfizer’s obligation to offer discounts to 340B Program covered entities under the program. See the Item 1A. Risk FactorsPricing and Reimbursement section.
States seek to control healthcare reformcosts related to Medicaid and other state regulated healthcare programs. A majority of states use preferred drug lists to manage access to pharmaceutical products under Medicaid, including some of our products. States may seek to negotiate supplemental rebate agreements that are larger than the minimum federal requirement for preferred formulary access. Preferred access to our products under the Medicaid managed care programs are often determined by the managed care health plans contracted by the state to administer benefits, which may also require supplemental rebates for preferred formulary access. We expect states will notcontinue to seek cost cutting, which may focus on managed care capitation payments, supplemental rebates, and/or formulary management.
We expect to see continued focus by Congress and the Biden Administration on regulating pricing and access to medicine, in addition to actions already taken, which could result in legislative and regulatory changes. Government and private payors routinely seek to manage utilization and control the costs of our products. There is considerable public and government scrutiny of pharmaceutical pricing and actions being taken at the state and federal level. Further efforts by states and the federal government to regulate prices or payment for pharmaceutical products, including proposed actions to facilitate drug importation, such as Florida’s drug importation program which was recently authorized by the FDA, limit reimbursement to lower reference prices, require deep discounts, impose financial penalties related to pricing practices, and require manufacturers to report and make public price increases and sometimes a written justification for the increase, could adversely affect our future business if implemented. Further, commercial payors often follow Medicare coverage and financial results.reimbursement policies when setting their own payment rates. Any reduction in cost or other containment measures may similarly be adopted by commercial plans. Payors may continue to promote generic drugs and biosimilars more aggressively to generate savings and attempt to stimulate additional price competition. In addition, we expect that consolidation and integration among pharmacy chains, wholesalers and PBMs will increase pricing pressures in the industry. See the Item 1A. Risk FactorsManaged Care Trends section.


Anti-Corruption.The FCPA prohibits U.S. corporations and their representatives from offering, promising, authorizing or making payments to any foreign government official, government staff member, political party or political candidate in an attempt to obtain or retain business abroad. The scope of the FCPA includes interactions with certain healthcare professionals in many countries. Other countries have enacted similar anti-corruption laws and/or regulations.


Data Privacy. The number of privacy and data security laws and regulations in the U.S. to which we are subject on the federal and state level continues to increase. We routinely collect and use sensitive personal information relating to digital health. The legislative, regulatory and litigation landscape for privacy and data protection requirements is rapidly evolving and changing. These requirements are not universal and can conflict between jurisdictions. Compliance with those laws and regulations is made more complex by the lack of consistent standards, common definitions, or clear regulatory expectations. At the same time, enforcement of these laws and regulations is increasing and litigation is becoming more common. Any failure or perceived failure by us to comply with applicable privacy and data protection laws and regulations, including cybersecurity breaches or incidents, could subject us to significant fines and penalties, litigation, and negatively impact our reputation.

Outside the United StatesU.S.

We encounter similar regulatory and legislative issues in most other countries.

New Drug Approvals.Approvals. In the EU, the approvalEMA conducts the scientific evaluation, supervision and safety monitoring of new drugsour innovative medicinal products that are eligible for the centralized marketing authorization procedure. Through the centralized procedure, pharmaceutical companies may be achieved usingsubmit to the Mutual Recognition Procedure, the Decentralized Procedure orEMA a single application for a marketing authorization valid in all the EU Centralized Procedure. These procedures apply in the EU member states, plusand the European Economic Area countries, Norway, Iceland and Liechtenstein.(EEA) countries. The Centralized Procedure, managed byEC takes a legally binding decision based on the EMA, results in one single authorizationEMA's recommendation. For medicinal products that are not eligible for the wholecentralized procedure, the mutual recognition procedure is based on the recognition of a pre-existing national marketing authorization by one or more EU which providesmember states, and the most rapiddecentralized procedure allows the submission of a marketing authorization application simultaneously in several EU member states. In the U.K., the Medicines and efficient means of gaining approval across the EU andHealthcare Products Regulatory Agency is the one most commonly used for new products.

sole regulatory authority. In Japan, the PMDA is the point of entry for businesses looking to sell drugs in the country. The PMDA, whichPharmaceuticals and Medical Device Agency is involved in a wide range of regulatory activities, including clinical studies, approvals, post-marketing reviews and pharmaceuticals safety, must approve an application before a new drug product may be marketed in Japan. The PMDA also offers consultations on clinical trials of new drugspharmaceutical safety. In China, the National Medical Product Administration is the primary regulatory authority for approving and provides advice on product classifications and approvals.

Historically, China’s regulatory system has presented numerous challenges for the pharmaceutical industry, as its requirements for drug development and registration have not always been consistent with U.S. or other international standards. The CFDA, however, has introduced reforms and draft reforms in recent years, which are discussed in more detail below, that attempt to address these challenges, with 2017 being an especially active year in this respect. In the past, it has been common to see treatments entering the Chinese market two to eight years behind first marketing in the U.S. and Europe, because historically China has only issued import drug licenses to treatments approved by mature regulatory authorities such as the FDA or the EMA. In addition, to obtain marketing approvals for new drugs in China, a clinical trial authorization issued by the CFDA has historically been required for the conduct of Phase I to III clinical trials. Applications for approval of imported drugs that included China-originated data in their Multi-Regional Clinical Trials and met the relevant technical review requirements were allowed to receive local clinical trial waivers on a case-by-case basis. Historically, oral generics only had to undergo bioequivalence studies upon a filing for record with the CFDA, while sterile injectable generics often needed local confirmatory trials for regulatory approval. A Chinese drug license would only be granted if, following review, the CFDA determines that the clinical data confirm the drug’s safety and effectiveness.

supervising medicines. Health authorities in many middlemiddle- and lower incomelower-income countries might require marketing approval or scientific opinions by a recognized regulatory authority (i.e.(e.g., similar to the authority of the FDA or the EMA) before they begin reviewing or approving applications. By way of example, the EMA, in cooperation with the World Health Organization (WHO), can provide scientific opinions on high priority human medicines, including vaccines, for markets outside the EU.
In April 2023, the EC proposed to conduct their application reviewrevise the EU pharmaceutical legislation. The proposed legislation includes a significant focus on tackling inequalities on access, affordability and availability of medicines across the EU.

There are also additional extensive requirements regarding adverse drug reaction reporting and additional monitoring of products.conducts pharmacovigilance audits. Outside developed markets, such as the EU and Japan, pharmacovigilance requirements vary and are generally not as extensive, but there is a trend toward increasing regulation.

Pricing and Reimbursement. In Europe,Certain governments, including in the different EU member states, the U.K., Japan, China, Canada and South Korea, and some other international markets, governments provide healthcare at low-to-zero direct cost to consumers at the point of care and have significant power as large single payers to regulate pharmaceutical

prices or patient reimbursement levels to control costs for the government-sponsored healthcare system, particularly under recent global economicfinancing pressures. Governments including the different EU Member States,globally may use a variety of cost-containment measures for our pharmaceutical products,to control costs, including, among others, legislative or regulatory pricing reforms, cross country collaboration and procurement, price cuts, mandatory rebates, health technology assessments, and internationalforced localization as a condition of market access, “international reference pricingpricing” (i.e., the practice of a country linking its regulated medicine prices to those of other countries). This, QCE processes and VBP. In addition, the international patchwork of price regulation, and differing economic conditions and incomplete value assessments of value across countries has led to different pricesvarying access to quality medicines in different countries, varying health outcomesmany markets and some third-party trade in our products between countries.

In particular, international reference pricing adds to the regional impact of price cuts in individual countries and can hinder patient access and innovation. Price variations, exacerbated by international reference pricing systems, also have resulted from exchange rate fluctuations. The downward pricing pressure resulting from this dynamic can be expected to continue as a result of reforms to international reference pricing policies and measures targeting pharmaceuticals in some European countries.

In addition, several Several important multilateral organizations such as the United Nations (UN) and the Organization for Economic Cooperation and Development (OECD), are increasing scrutiny ofWHO scrutinize international pharmaceutical pricing through issuing reports and policy recommendations (e.g., 2016 UN High Level Panel Report onand sponsorship of programs, such as “The Oslo Medicines Initiative” (OMI) which aims to ensure “affordability for high-priced medicines”.

Government adoption of these recommendations may lead to additional pricing pressures.

In Japan,China, pricing pressures have increased in recent years because of an overall focus on healthcare cost containment with the central government recently releasedemphasizing improved health outcomes and decreased drug prices as key indicators of progress towards its healthcare reform. State owned hospitals and the state insurance program account for the vast majority of all drug purchases. For patented innovative products, drug prices have decreased dramatically as a basic frameworkresult of adding innovative drugs (including oncology medicines, medicines for pharmaceutical pricing that will leadchildren and orphan drugs) to the adoptionNational Reimbursement Drug List via access-price negotiation. A centralized VBP program with a tendering process aims to contain healthcare costs by driving utilization of cost effectiveness assessmentsgenerics that have passed QCE. This has resulted in some form, quarterly pricing reviews for new indications, and severe narrowingfurther lowering the price of the criteria to gain a price maintenance premium. In China, despite removal of government-set price caps the government continues to exercise indirect price control by setting reimbursement standards through a negotiation mechanism between drug manufacturers and social insurance administrations. Provincial biddings, cross-regional procurement and secondary hospital price negotiations are likely to intensify as government cost containment efforts continue.

EU Regulatory Changes. The EU adopted a new Clinical Trials Regulation in May 2014, whichmedicines, especially off-patent medicines; this trend is expected to come into effect some time in late 2019. This regulationcontinue. China is aimed at simplifyingincreasing its use of Health Technology Assessment and harmonizingis controlling mark-ups within the governancecountry using a two-invoice limited system, which is a government policy that regulates the pricing of clinical trialspharmaceutical products and medical devices. Pfizer, along with most off-patent originators, have mostly not been successful in the EUVBP bidding process. The government has indicated that additional post-LOE drugs (including biological products) could be subjected to VBP qualification in future rounds. Certain of our products, such as Sulperazon and will require increased public postingVfend injectables, were included as candidates in VBP rounds in 2023, and Pfizer was not successful in the bidding process for such products. While certain details of clinical trial results.

The policy includes limited exceptions for commercially confidential information and the exclusion of any protected personal data.

Brexit. In June 2016, the U.K. electorate voted in a referendum to leave the EU, which is commonly referred to as “Brexit”. In March 2017, the U.K. government formally notified the European Council of its intention to leave the EU after it triggered Article 50our business of the Lisbon Treaty to begin the two-year negotiation process establishing the terms of the exit and outlining the future relationship between the U.K. and the EU. Formal negotiations officially started in June 2017. This process continues to be highly complex and the end result of these negotiations may pose certain implications to our research, commercial and general business operations in the U.K. and the EU, including the approval and supply of our products. It was announced in November 2017 that the EMA will be relocating from London, U.K. to Amsterdam, Netherlands by the expected date of Brexit in March 2019. At present, it is still unclear whether and to what extent the U.K. will remain within or aligned to the EU system of medicines regulation, and/or what separate requirements will be imposed in the U.K. after it leaves the EU. For additional information on Brexit, see the Analysis of Financial Condition, Liquidity and Capital ResourcesGlobal Economic ConditionsU.K. in our 2017 Financial Report.various pricing measures underway.

China Regulatory Changes. In an effort to encourage drug innovation and reduce backlogs for existing applications for drug approval, the CFDA has unveiled numerous reform initiatives for China’s drug approval system, and engaged in significant efforts to build its capabilities. The CFDA now divides drugs into new drugs and generics, with the definition for new drugs changed from “China New” to “Global New.” This means that drugs previously approved in other markets (such as the U.S. or Europe) will not be considered new drugs under China’s regulatory regime, with the exception of drugs introduced within one year of approval in mature markets. This change in definition creates more opportunities for China’s domestic drug manufacturers than for multinational firms, because multinational firms have historically had significant competitive advantage in successfully achieving regulatory approvals for drugs first approved outside of China. The 2017 revisions made clear, however, that regulatory approval from the FDA or the EMA would no longer be required for approval of imported drugs, though a notable exception persists for imported vaccines, which still require prior approval from a relevant regulatory agency. The “marketing authorization holder” system, which will allow for more flexibility in contract manufacturing arrangements and asset transfers, now applies to all drugs developed and manufactured in China, but not yet to imported drugs.

While challenges remain, a number of other policy changes are streamlining and accelerating approvals of domestic and imported drugs in China. These reforms, along with China’s June 2017 entry into the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use, are expected to pave the way for integration of CFDA’s regulations with global practices. These changes include introducing an umbrella clinical trial authorization for all three phases of registration studies (instead of the original phase-by-phase approvals), a filing/recordation system for bioequivalence studies on generics (instead of the original review and approval system), admitting more categories of drugs as innovative drugs eligible for the fast track/“green channel” approval pathway and ongoing implementation of previously announced regulatory reforms.

Healthcare Provider Transparency and Disclosures.A number ofSeveral countries have implemented laws requiring (or their industry trade associations have recommended) disclosure of transfers of value made by pharmaceutical companies to healthcare providers. For example,providers and/or healthcare organizations, such as academic teaching hospitals.
Intellectual Property. Reliable patent protection and enforcement around the EFPIA’s disclosure code requires all members, including Pfizer, to disclose transfers of value to healthcare professionalsworld are among the key factors we consider for continued business and healthcare organizations.

Intellectual Property.R&D investment. The World Trade OrganizationWTO Agreement on Trade Related Aspects of Intellectual Property Rights (WTO-TRIPS) requiredrequires participant countries to amend theirprovide patent and other intellectual property laws to provide patentproperty-related protection for pharmaceutical products by 2005,law, with an extension until 2033a time-limited exemption provided for least-developed countries. While some countries have made improvements, we still face patent grant, enforcement and other intellectual property challenges around the world, some countries have made improvements. We include stronger patent protection among the factors we consider for continued business expansion in other participantmany countries.

While the global intellectual property policy environment has generally improved following implementation of WTO-TRIPS and bilateral/multilateral trade agreements, our future business growth and ability to bring new product innovation to patients depends on maintaining those standards and further progress in intellectual property protection. In certain developed international markets, governments maintain relatively effective intellectual property policies. However, in the EU, pursuant to the ongoing review of pharmaceutical intellectual property and regulatory incentives, proposals introduced in 2023 may reduce the basic period of regulatory data protection from eight to six years, subject to the outcome of the ongoing legislative procedure. In several emerging market countries, in particular, governments have used intellectual property policies as a tool to force innovators to accept less than fair value for reducing the price of imported medicines, as well as to protect their local pharmaceutical industries. There is considerableadvance industrial policy and localization goals. Multilateral institutions continue to address the role of intellectual property in the context of the COVID-19 response, as well as pandemic preparedness and access to medicine more generally.
Considerable political and economic pressure to weaken existinghas weakened current intellectual property protection in some countries and resist implementation of any further protection, which has led to policies such as more restrictive standards for obtaining patents and more difficult procedures for patenting biopharmaceutical inventions, restrictions on patenting certain types of inventions, (e.g., new medical treatment methods), revocation of patents, issuance (and threat of issuance) oflaws or regulations that promote or provide broad discretion to issue a compulsory licenses,license, weak intellectual property enforcement and failure to implement effective regulatory data protection. Our industry advocacy efforts focus on seeking a more balancedfair and transparent business environment for foreign manufacturers, as well as on underscoring the importance of strong intellectual property systems for localall innovative industries. In developed countries as well, including the EU, weindustries (both domestic and foreign) and helping improve patients’ access to innovative medicines and vaccines.

Data Privacy. We are facing an increasingly challenging intellectual property environment.

Canada’s intellectual property regime for drugs provides some level of patent protectionsubject to extensive privacy and data exclusivity (eight years plus six-month pediatric extension), but it lacksprotection laws and regulations around the predictabilityworld concerning the collection, use and stability that otherwise comparable countries provide. Through intense negotiations as partsharing of the Canada/EU Comprehensive Economic & Trade Agreement (CETA), Canadian authorities reluctantly agreedpersonal data. We routinely collect and use sensitive personal information relating to introduce a right of appeal, a form of patent term restorationdigital health. The legislative, regulatory and to elevate the currentlitigation landscape for privacy and data protection to a treaty obligation, further aligning its intellectual property regime torequirements is rapidly evolving and changing. These requirements are not universal and can conflict between jurisdictions. Compliance with those laws and regulations is made more complex by the EU. In particular, CETA Article 20.25 provides sui generis protection for patent term extensions of two to five years for basic patents, subject to various rules and limitations.

In China, the intellectual property environment has improved, although effective enforcement and adequate legal remedies remain areas of concern. The government has taken steps to protect intellectual property rights in conformity with World Trade Organization provisions, and several companies, including Pfizer, have established R&D centers in China due to increased confidence in China’s intellectual property environment. Despite this, China remained on the U.S. Trade Representative’s Priority Watch List for 2017. Further, the standards for patentability in China remain more restrictive than in other major markets, including the U.S., Europe and Japan. Also, while a framework exists for protecting patents for 20 years, enforcement mechanisms are often lacking or inconsistent. For example, the absence of effective patent linkage mechanisms and preliminary injunctions, impractical evidentiary burdens, and heightened sufficiency standards have been used to invalidate patents at the enforcement stage.

In Brazil and other Latin American countries, the role of health regulatory authorities in reviewing patents (e.g., National Health Surveillance Agency in Brazil), restrictive patentability rules, ambiguity regarding the term of certain patents and backlogs at patent agencies may limit our ability to protect our products through patents. The lack of consistent standards, common definitions, or clear regulatory expectations. At the same time, enforcement of these laws and regulations is increasing and fines and penalties are also increasing. Any failure or perceived failure by us to comply with applicable privacy and data protection laws and difficulties in protecting certain types of inventions, such as new medical uses of drug products, may limit the commercial lifespan of some pharmaceutical products.regulations, including cybersecurity breaches or incidents, could subject us to significant fines and penalties, litigation, and negatively impact our reputation.

In India, we have seen some progress in terms of expediting patent approval processes to reduce pendency rates and implementing training programs to enhance enforcement. Despite these positive steps, gaps remain in terms of addressing longstanding intellectual property concerns. For example, policies favoring compulsory licensing of patents, the tendency of the Indian Patent Office to revoke pharmaceutical patents in opposition proceedings (both pre- and post-grant), and restrictive standards for patentability of pharmaceutical products have made it difficult to safeguard many of our inventions and our investments in innovation. These policies heighten the risk of additional patent challenges targeting innovative pharmaceutical products, especially in areas perceived as being important to the public health of the population. Challenges against Pfizer patents in India are ongoing.
ENVIRONMENTAL MATTERS

As part of this goal, Pfizer aims to decrease its GHG emissions by 95% and its value chain emissions by 90% from 2019 levels by 2040. To support our goal, we are developing and implementing our emission reduction plan, which will include strategies to achieve reductions throughout our value chain including the potentialinvesting in new technologies and innovative climate solutions, and setting expectations for additional regulatory requirementsour suppliers to establish science-aligned GHG emission reduction goals. Our emission reduction plan-related expenses and associated costs, and the potentialcapital spending incurred for more frequent and severe weather events and water availability challenges that may impact our facilities and those of our suppliers.

Basis of Presentation and Significant Accounting Policies and —Note 5. Tax Matters; plans relating to increasing investmentDecember 31, 2023, including Seagen colleagues, we employed approximately 88,000 people worldwide, with approximately 35,000 based in the U.S. followingWomen compose approximately 52% of our global workforce, and approximately 39% of our U.S.-based employees are individuals with ethnically diverse backgrounds.
Our continued success links directly to the expectedcommitment, engagement and performance of our employees. It is important that we not only attract and retain the best and brightest talent, but also ensure they remain engaged and can thrive in an environment that is committed to helping them grow, succeed and contribute directly to achieving our purpose. At Pfizer, prioritizing a positive net impactcolleague experience is of utmost importance, particularly during times of business transformation. We were conscious of the Tax Cutsimpact that the challenges and Jobs Actopportunities facing our business throughout the year had on colleagues. Our goal is to prioritize the health and wellness of our colleagues, creating an environment where colleagues can excel in their work and advance our purpose. To achieve this, we strive to cultivate an inclusive and empowering work environment. This involves simplifying processes and eliminating unnecessary complexity, recognizing both performance and leadership skills, fostering career growth and internal mobility, and providing competitive compensation and benefits programs that promote mental and physical well-being.
Core Values.To fully realize Pfizer’s purpose we have established a clear set forthof goals regarding what we need to achieve for patients and how we will go about achieving them. The “how” is represented by four simple, powerful company core values – Courage, Excellence, Equity and Joy.
Each value defines our company and our culture:
Courage: Breakthroughs start by challenging convention – especially in the Overviewface of Our Performance, Operating Environment, Strategyuncertainty or adversity. This happens when we think big, speak up and Outlook––Our Strategy––Capital Allocationare decisive.
Excellence: We can only change patients’ lives when we perform at our best together. This happens when we focus on what matters, agree who does what and Expense Management sectionmeasure outcomes.
Equity: Every person deserves to be seen, heard and cared for. This happens when we are inclusive, act with integrity and reduce healthcare disparities.
Joy: We give ourselves to our work, and it also gives to us. We find joy when we take pride, recognize one another and have fun.
Diversity, Equity and Inclusion. At Pfizer, every person deserves to be seen, heard and cared for. We embed diversity, equity and inclusion in our 2017 Financial Report;workplace and our purpose of delivering breakthroughs that change patients’ lives. As we work to bring together people with different backgrounds, perspectives and experiences we take specific actions to help foster an inclusive environment within Pfizer and beyond, including, among others: (i) building a more inclusive colleague experience through representation and meaningful connections; (ii) advancing equitable health outcomes by evaluating our work through the financiallens of the communities we serve, (iii) providing resources on allyship and the science behind inclusion to support all colleagues in having courageous conversations about equity, race and the avoidance of bias; (iv) working to help transform society with external diversity, equity and inclusion partnerships, including deploying capital, engaging diverse suppliers and amplifying equity initiatives; and (v) working to help ensure demographics of clinical trials correlate to those of the countries where trials are taking place.
Colleague Engagement. To attract, develop and inspire the brightest talent, we aim to support our colleagues by engaging and partnering with them to help ensure they feel they are part of a community. We understand that continuously listening and responding to colleague feedback is essential to fostering a healthy work environment particularly during times of change and uncertainty. We are passionate about creating safe spaces at work so our employees feel able and encouraged to provide the company with feedback. The Office of the Ombuds is a resource where all Pfizer colleagues at any level can come to get information and guidance set forthto help them address and resolve work-related issues. We also host company-wide safe space calls and provide various other public, private and anonymous channels for employees to share feedback without fear of retaliation.
Our annual engagement survey, Pfizer Pulse, provides a forum for our colleagues to give structured feedback about their colleague experience. Through this survey, we measure and track priority areas of the overall colleague experience and equip leaders with actionable insights for discussion and follow up. Regular topics in the Overviewsurvey include: (i) employee engagement, such as colleagues’ commitment to and advocacy for Pfizer; (ii) purpose, including how colleagues’ work connects with our purpose; (iii) inclusion, such as having a climate in which diverse perspectives are valued; (iv) empowerment, such as colleagues feeling empowered and enabled to do their best work together; and (v) growth, including the ability for colleagues to gain new experiences that align with their individual career goals. In addition, we ask for feedback at various points in the employee lifecycle through surveys, focus groups and colleague forums. The information we receive helps enable us to adapt to the real-time needs of our employees and continuously improve our ways of working. While we have already made progress in reducing bureaucracy and streamlining processes, we recognize that there is still room for improvement, particularly in the effectiveness of our cross-functional teams.
Throughout 2023, we have developed and tested a new approach that aims to expedite decision-making, provide clarity in roles and responsibilities, enhance governance, redefine the role of a leader, and ultimately improve overall team productivity and performance. This new way of working signifies our commitment to becoming a more dynamic organization that thrives on collaboration and agility. By revolutionizing the way our teams operate, we believe we can drive better business outcomes and, most importantly, make a meaningful difference in the lives of people around the world.
Pfizer also prioritizes colleague recognition to drive engagement, a sense of belonging, motivation, and productivity. Our global rewards and recognition program, Bravo, lets colleagues celebrate and acknowledge each other for demonstrating Pfizer values in a way that makes an impact on the company, a colleague, a team or a patient. In 2023, 84% of colleagues were recognized, and more than 650,000 recognitions were given.

Pfizer Inc.2023 Form 10-K15


Performance Operatingand Leadership.We understand the significance of leadership and its crucial role in promoting growth and delivering breakthrough results. We believe that each of our colleagues has the potential to lead in a unique way and create a meaningful impact on a global scale. To support this belief, we have developed a new leadership profile for our colleagues that aligns with our company values of courage, excellence, equity and joy.
We believe this renewed focus on leadership applies to all colleagues, which may help us to foster transformational thinking and executional excellence. By pursuing these leadership qualities, we believe Pfizer can help ensure that its leaders and colleagues are aligned with the company’s values, behaviors and purpose, which may help lead to better outcomes and a positive impact on the lives they touch.
We are committed to helping our colleagues reach their full potential by rewarding both their performance and leadership skills and by providing opportunities for growth and development. Our performance management approach—called Performance and Leadership Insights—is based on six-month semesters during which our colleagues and their managers set goals, receive feedback and meet to discuss performance. These conversations are meant to help colleagues grow and develop by evaluating performance (what the colleague achieved, measured by outcomes), leadership (how they achieved it, taking into account Pfizer’s values of courage, excellence, equity and joy), and identifying areas of growth that help move colleagues towards fulfilling their career goals and their potential.
Growth and Development. By prioritizing the ongoing development of our employees, we not only support their individual success but also cultivate a resilient and adaptable workforce that can thrive in the face of change. As we navigate the evolving landscape of our industry, we recognize that providing our employees with opportunities for learning, skill-building and growth is essential to their engagement, productivity, and overall job satisfaction. In 2023, we continued to maintain low voluntary turnover rates relative to the pharmaceutical industry.
Our view of career growth is built on aspirations and empowers individuals to boldly own their growth journey. We deepened our efforts to redefine growth as a fluid process that promotes incremental in-role growth or mobility along horizontal, vertical or diagonal individualized pathways—what we are calling “zig-zag” growth. Our commitments to colleague development consist of specific actions to encourage non-linear “zig-zag” career growth paths for all colleagues, including (i) a common language around growth—along with a guiding framework—to help colleagues identify their next best growth experience, (ii) tools and resources to encourage growth conversations and offer transparency on the sources of growth available, and (iii) a variety of opportunities to grow through experiences, connections with others and learning programs, including mentoring, job rotations, experiential projects, skill-based volunteering and personalized learning pathways that address a variety of topics, including leadership and management skills and industry- and job-specific learning, as well as general business, manufacturing, finance and technology skills.
Health, Safety and Well-Being. Protecting the health, safety and well-being of colleagues and contingent workers, all of whom are essential to delivering our business objectives, is an integral part of how we operate. Our Global Environment, StrategyHealth & Safety (EHS) Policy and Outlook—supporting standards outline our approach to assessment, evaluation, elimination, and mitigation of EHS risks across our operations globally. We are committed to supporting and encouraging our colleagues’ well-being and use results from Pfizer Pulse and other employee feedback forums to inform the wellness services we offer, such as (i) a Wellness Day for every colleague, (ii) on-site health clinics for colleagues in select locations, with access to certain vaccinations, where allowed by law, (iii) digital accessibility cafés that provide employees with disabilities the tools and equipment to do their jobs effectively, (iv) mental health resources, including a manager/team toolkit designed to facilitate conversations, actively care for coworkers, and provide local resources for employees to access support, (v) programming through Employee Assistance Program (EAP) providers, including our mental health partner THRIVE, our fitness partner Exos, and healthcare partner Kepro, (vi) financial support, including short-term loans and natural disaster relief, and (vii) flexible work policies enabling employees to work from home and their local offices.

The growing availability and use of innovative specialty pharmaceutical medicines that treat rare or life threatening conditions, typically with a relatively higher cost as compared to other types of pharmaceutical products, or obtaining such pricing or placement at unfavorable pricing could adversely impact revenue. In addition to formulary tier co-pay differentials, private health insurance companiesalso has generated increased payor interest in development of cost-containment strategies. These initiatives have increased consumers’ interest in drug prices and self-insured employers have been raising co-payments required from beneficiaries, particularly for branded pharmaceuticals and biotechnology products. They are also trying newer programs like copay accumulators to shift more of the cost burden to manufacturers and patients.

Also, generic manufacturers have filed applications with the FDA seeking approvalin various stages of product candidates that such companies claim do not infringe our patents; these include candidates that would compete with, among other products, Xeljanz and Xtandi. Our licensing and collaboration partners also face challenges by generic drug manufacturers to patents covering products for which we have licenses or co-promotion rights. In addition, our patent-protected products may face competition in the form of generic versions of competitors’ branded products that lose their market exclusivity.

Some of our competitors may have competitive, technical or other advantages over us for the development of technologies and processes or greater experience in particular therapeutic areas, and consolidation among certain pharmaceutical and biotechnology companies can enhance such advantages. These advantages may make it difficult for us to compete with them successfully to discover, develop and market new products and for our current products to compete with new products or indications they may bring to market. Our products have been competing and may continue to compete, and our product entrants, in-line brandedcandidates may compete, against products generic products, private label products, biosimilars andor product candidates that treat diseases and conditions similaroffer higher rebates or discounts, exclusionary contracting, lower prices, equivalent or superior efficacy, better safety profiles, easier administration, earlier market availability or other competitive features. If we are unable to those treated bycompete effectively, this could reduce sales, which could negatively impact our results of operations.
In addition, competition from manufacturers of generic drugs, including from generic versions of competitors’ branded products that lose their market exclusivity, is a major challenge for our branded products. Certain of our products have experienced significant generic competition over the last few years. We anticipate a more significant impact of reduced revenues from patent expiries in 2026 through 2030 as several of our in-line drugsproducts experience patent-based expirations. See the Item 1.

In China, we expect to continue to face intense competition by certain generic manufacturers, which has resulted, and may result in erosionthe future, in price cuts and volume loss of the salessome of our existingproducts.

We and our licensing and collaboration partners also face challenges in other countries.various jurisdictions by generic drug manufacturers to patents covering products for which we have patent rights, licenses or co-promotion rights. See Note 16A1.

We may become subject to competition from biosimilars referencing our biologic products if competitors are able to obtain marketing approval for such biosimilars.

The abilityentry to launch a generic or biosimilar pharmaceutical product at or before the anticipated formationmarket of the generic or biosimilar marketplacecompeting biosimilars is importantexpected to that product’s profitability. Prices for products typically decline, sometimes dramatically, following generic or biosimilar entry, and as additional companies receive approvals to market that product, competition intensifies. If a company’s generic or biosimilar product can be “first-to-market” such that its only competition is the branded drug for a period of time, higher levels of sales and profitability can be achieved until other generic or biosimilar competitors enter the market. With increasing competition in the generic or biosimilar product market, the timeliness with which we can market new generic or biosimilar products will increase in importance. Our success will dependpricing pressures on our abilitybiosimilar products. Uptake of our biosimilars may be lower due to bring new products to market quickly.

Patents coveringsignificant and our revenue forecasts and expectations could prove to be inaccurate and we may fail to meet these expectations. In particular, certain of our products have experienced patent-based expirations or loss of regulatory exclusivity in certain markets in the last few years. We anticipate a more significant impact of reduced revenues from patent expiries in 2026 through 2030 as several of our best-selling medicines have recently expired or will expire in the next few years (including some of our billion-dollar and previously billion-dollar products), andin-line products experience patent-based expirations. In addition, patents covering a number of our best-selling medicinesproducts are, or have been, the subject of pending legal challenges. For example, as a result of a patent litigation settlement, Teva Pharmaceuticals USA, Inc. launched a generic version of Viagra in the U.S. in December 2017. In addition, our revenues could be significantly impacted by the timing and rate of commercial acceptance of key new products.

For information on risks associated with Comirnaty and Paxlovid, see the COVID-19 section below.
In addition, certain of our businesses. Our product lines must be replenished over time in order to offset revenue losses when products lose their market exclusivity, as well as to providecustomers account for earnings growth. Our growth potential 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, either through internal R&D or through collaborations, acquisitions, joint ventures or licensing or other arrangements with third parties. However, balancing current growth, investment for future growth and the delivery of shareholder return remains a major challenge. The average costs of product development continue to rise, as do the regulatory requirements in many therapeutic areas, which may affect the number of candidates funded as well as the sustainability of the R&D portfolio. Our ongoing investments in new product introductions and in R&D for new products and existing product extensions could exceed corresponding sales growth.

Additionally, our R&D investment plans and resources may not be correctly matched between science and markets, and failure to invest in the right technology platforms, therapeutic segments, product classes, geographic markets and/or in-licensing and out-licensing opportunities in order to deliver a robust pipeline could adversely impact the productivitysignificant portion of our pipeline. Further, even if the areas with the greatest market attractiveness are identified, the science may not work for any given program despite the significant investment required for R&D, and the commercial potential of 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.

We continue to strengthen our global R&D organization and pursue strategies intended to improve innovation and overall productivity in R&D to achieve a sustainable pipeline that will deliver value in the near term and over time. There can be no assurance that these strategies will deliver the desired result, which could affect profitability in the future.

Abbreviated legal pathways for the approval of biosimilars exist in certain international markets and, since the passage of the ACA, a framework for such approval exists in the U.S. If competitors are able to obtain marketing approval for biosimilars referencing our biotechnology products, our biotechnology products may become subject to competition from these biosimilars, with attendant competitive pressure, and price reductions could follow. For example, Enbrel faces ongoing biosimilar competition in most developed Europe markets, which is expected to continue. The expiration or successful challenge of applicable patent rights could trigger this competition, assuming any relevant regulatory exclusivity period has expired. We may face litigation with respect to the validity and/or scope of patents relating to our biotechnology products.

We are developing biosimilar medicines. The evolving pathway for registration and approval of biosimilar products by the FDA and regulatory authorities in certain other countries could diminish the value of our investments in biosimilars. Other risks related to our development of biosimilars include the potential for steeper than anticipated price erosion due to increased competitive intensity, coupled with high costs associated with clinical development or intellectual property challenges that may preclude timely commercialization of our potential biosimilar products. There is also a risk of lower prescriptions for biosimilars due to potential concerns over comparability with innovator medicines. See also the Competitive Products risk factor above.

RESEARCH STUDIES

Decisions about research studies 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 it receives regulatory approval. For example, a wider range of studies can lead to approval for a broader set of indications that may impact the marketing and payer reimbursement process. However, each additional indication must be balanced against the time and resources required to demonstrate benefit, the increased complexity of development and the potential delays to approval of the lead indication. We try to plan clinical trials prudently and to reasonably anticipate and address challenges, but there is no guarantee that an optimal balance between trial conduct, speed and desired outcome will be achieved each time. The degree to which such potential challenges are foreseen and addressed could affect our future results.

RISKS AFFECTING INTERNATIONAL OPERATIONS

Our international operations could be affected by currency fluctuations, capital and exchange controls, expropriation and other restrictive government actions, changes in intellectual property legal protections and remedies, trade regulations and procedures and actions affecting approval, production, pricing, and marketing of, reimbursement for and access to our products, as well as by political unrest, unstable governments and legal systems and inter-governmental disputes. Any of these changes could adversely affect our business.

Many emerging markets have experienced growth rates in excess of developed markets, leading to an increased contribution to the industry’s global performance. As a result, we have been employing strategies to grow in emerging markets. However, there is no assurance that our strategies in emerging markets will be successful or that these countries will continue to sustain these growth rates. In addition, some emerging market countries may be particularly vulnerable to periods of financial or political instability or significant currency fluctuations or may have limited resources for healthcare spending. Even though we constantly monitor the evolving emerging markets for any unanticipated risk to Pfizer, certain financial or political events in such markets, as discussed above, can adversely affect our results.

SPECIALTY PHARMACEUTICALS

Specialty pharmaceuticals are medicines that treat rare or life-threatening conditions that typically have smaller patient populations. The growing availability and use of innovative specialty pharmaceuticals, combined with their relative higher cost as compared to other types of pharmaceutical products, has generated payer interest in developing cost-containment strategies targeted to this sector. The impact of payers’ efforts to control access to and pricing of specialty pharmaceuticals is increasing. For Pfizer to date, a number of factors create a more challenging paradigm given our growing specialty business portfolio. These include formulary restrictions and dispensation barriers, such as step edits, leading to higher negotiated rebates or discounts to health plans and PBMs in the U.S., as well as the increasing use of health technology assessments in markets around the world.

CONSUMER HEALTHCARE

The Consumer Healthcare business may be impacted by economic volatility, the timing and severity of the cough, cold and flu season, generic or store brand competition affecting consumer spending patterns and market share gains of competitors’ branded products or generic store brands. In addition, regulatory and legislative outcomes regarding the safety, efficacy or unintended uses of specific ingredients in our Consumer Healthcare products may require withdrawal, reformulation and/or relabeling of certain products (e.g., cough/cold products). See The Global Economic Environment and Strategic Alternatives for Pfizer Consumer Healthcare risk factors below.

PRODUCT MANUFACTURING, SALES AND MARKETING RISKS

Difficulties or delays in product manufacturing, sales or marketing could affect future results through regulatory actions, shut-downs, approval delays, withdrawals, recalls, penalties, supply disruptions or shortages, reputational harm, product liability, unanticipated costs or otherwise. Examples of such difficulties or delays include, but are not limited to, the inability to increase production capacity commensurate with demand; the failure to predict market demand for, or to gain market acceptance of, approved products; the possibility that the supply of incoming materials may be delayed or become unavailable and that the quality of incoming materials may be substandard and not detected; the possibility that we may fail to maintain appropriate quality standards throughout the internal and external supply network and/or comply with cGMPs and other applicable regulations such as serialization (which allows for track and trace of products in the supply chain to enhance patient safety); risks to supply chain continuity and commercial operations as a result of natural (including hurricanes, earthquakes and floods) or man-made disasters at our facilities or at a supplier or vendor, including those that may be related to climate change; or failure to maintain the integrity of our supply chains against intentional and criminal acts such as economic adulteration, product diversion, product theft, counterfeit goods and cyberattacks.

Regulatory agencies periodically inspect our drug manufacturing facilities to evaluate compliance with applicable cGMP requirements. Failure to comply with these requirements may subject us to possible legal or regulatory actions, such as warning letters, suspension of manufacturing, seizure of product, injunctions, debarment or voluntary recall of a product, any of

Pfizer Inc.2017 Form 10-K13

TABLE OF CONTENTS

which could have a material adverse effect on our business, financial condition and results of operations. In February 2017, we received a warning letter from the FDA communicating the FDA’s view that certain violations of cGMP regulations exist at Hospira’s manufacturing facility in McPherson, Kansas. We are undertaking corrective actions to address the concerns raised by the FDA. In January 2018, the FDA upgraded the status of Pfizer’s McPherson, Kansas manufacturing facility to Voluntary Action Indicated (VAI) based on an October 2017 inspection. The change to VAI status will lift the compliance hold that the FDA placed on approval of pending applications, and is an important step toward resolving the issues cited in the February 2017 FDA warning letter. In addition, in September 2017, Meridian, a subsidiary of Pfizer Inc., received a warning letter from the FDA asserting the FDA’s view that certain violations of cGMP and Quality System Regulations exist at Meridian’s manufacturing sites in St. Louis, Missouri. We are undertaking corrective actions to address the concerns raised by the FDA, and communication with the FDA is ongoing. Until the corrective actions are implemented and approved by the FDA, the FDA may refuse to grant premarket approval of applications and/or the FDA may refuse to grant export certificates related to products manufactured at our St. Louis, Missouri sites.

OUTSOURCING AND ENTERPRISE RESOURCE PLANNING

We outsource certain services to third parties in areas including transaction processing, accounting, information technology, manufacturing, clinical trial execution, clinical lab services, non-clinical research, safety services, integrated facilities management and other areas. For example, in 2017, we placed the majority of our clinical trial execution services with four Clinical Research Organizations (CROs). Service performance issues with these CROs may adversely impact the progression of our clinical trial programs. Outsourcing of services to third parties could expose us to sub-optimal quality of service delivery or deliverables, which may result in repercussions such as missed deadlines or other timeliness issues, erroneous data, supply disruptions, non-compliance (including with applicable legal requirements and industry standards) or reputational harm, with potential negative implications for our results.

We are migrating to a consistent enterprise resource planning system across the organization. These are enhancements of ongoing activities to standardize our financial systems. If any difficulties in the migration to or in the operation of our enterprise resource planning system were to occur, they could adversely affect our operations, including, among other ways, through a failure to meet demand for our products, or adversely affect our ability to meet our financial reporting obligations.

COLLABORATIONS AND OTHER RELATIONSHIPS WITH THIRD PARTIES

We depend on third-party collaborators, service providers, and others in the research, development and commercialization of our products and product candidates and also enter into joint ventures and other business development transactions in connection with our business. To achieve expected longer term benefits, we may make substantial upfront payments in such transactions, which may negatively impact our reported earnings. We rely heavily on these parties for multiple aspects of our drug development, manufacturing and commercialization activities, but we do not control many aspects of those activities. Third parties may not complete activities on schedule or in accordance with our expectations. Failure by one or more of these third parties to meet their contractual or other obligations to Pfizer; failure of one or more of these parties to comply with applicable laws or regulations; or any disruption in the relationships between Pfizer and one or more of these third parties, could delay or prevent the development, approval or commercialization of our products and product candidates and could also result in non-compliance or reputational harm, all with potential negative implications for our product pipeline and business.

BIOPHARMACEUTICAL WHOLESALERS

In 2017, our largest biopharmaceutical wholesaler accounted for approximately 16% of our total revenues (and approximately 33% of our total U.S. revenues), and our top three biopharmaceutical wholesalers accounted for approximately 38% of our total revenues (and approximately 79% of our total U.S. revenues).revenues. If one of our significant biopharmaceutical wholesalerscustomers should encounter financial or other difficulties, such wholesalerit might decrease the amount of business that itsuch customer does with us andand/or we might be unable to timely collect all the amounts that the wholesalersuch customer owes us on a timely basis 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. See Note 17Cfor a discussion of our significant customers.

RESEARCH AND DEVELOPMENT
BUSINESS DEVELOPMENT ACTIVITIESThe 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


Pfizer Inc.2023 Form 10-K17


new products or new indications for existing products that address unmet medical needs and receive reimbursement from payors. 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 and are growing, as are regulatory requirements in many therapeutic areas, which may affect the complexity of drug trials, and 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 payor 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 compounds or 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 regulatory and market environments and the hurdles in terms of access, coverage and reimbursement. For example, certain of our gene therapy product candidates are based on a novel technology with only a handful of gene therapies approved to date, which make it difficult to predict the time and cost of development and the ability to obtain regulatory approval.
GLOBAL OPERATIONS
We expectoperate on a global scale and could be affected by currency and interest rate fluctuations; capital and exchange controls; local and global economic conditions including inflation, recession, volatility and/or lack of liquidity in capital markets; expropriation and other restrictive government actions; changes in intellectual property; legal protections and remedies; trade regulations; tax laws and regulations; and procedures and actions affecting approval, production, pricing, and marketing of, reimbursement for and access to our products, as well as impacts of political or civil unrest or military action, including the ongoing conflicts between Russia and Ukraine and in the Middle East and their economic consequences, geopolitical instability, terrorist activity, unstable governments and legal systems, inter-governmental disputes, public health outbreaks, epidemics, pandemics, natural disasters or disruptions related to climate change.
Some emerging market countries may be particularly vulnerable to periods of financial, economic or political instability or significant currency fluctuations or may have limited resources for healthcare spending. As a result of these and other factors, our strategy to grow in emerging markets may not be successful, and any growth rates in these markets may not be sustainable. Additionally, local economic conditions may adversely affect the ability of payors, as well as our distributors, customers, suppliers and service providers, to pay for our products, or otherwise to buy necessary inventory or raw materials, and to perform their obligations under agreements with us.
Government financing and economic pressures can lead to negative pricing pressure in various markets where governments take an active role in setting prices, access criteria (e.g., through health technology assessments) or other means of cost control. For additional information on government pricing pressures, see the Item 1. Business—Government Regulation and Price Constraints section.
We continue to enhancemonitor the global trade environment and potential trade conflicts and impediments that could impact our in-line productsbusiness. If trade restrictions or tariffs reduce global economic activity, potential impacts could include declining sales; increased costs; volatility in foreign exchange rates; a decline in the value of our financial assets and product pipeline through collaborations, alliances, licensepension plan investments; required increases of our pension funding obligations; increased government cost control efforts; delays or failures in the performance of customers, suppliers and funding agreements, joint ventures, equity-other third parties on whom we may depend for the performance of our business; and the risk that our allowance for doubtful accounts may not be adequate.
We operate in many countries and transact in many different currencies. Changes in the value of those currencies relative to the U.S. dollar, or debt-basedhigh inflation or deflation in those countries, can impact our revenues, costs and expenses and our financial guidance. Significant portions of our revenues, costs and expenses, as well as our substantial international net assets, are exposed to exchange rate changes. 54% of our total 2023 revenues were derived from international operations, including 24% from Europe and 20% from Japan, China and the rest of the Asia Pacific region. Future changes in exchange rates or economic conditions and the impact they may have on our results of operations, financial condition or business are difficult to predict. For additional information about our exposure to foreign currency risk, see the Analysis of Financial Condition, Liquidity, Capital Resources and Market Risk section within MD&A.
In addition, our borrowing, pension benefit and postretirement benefit obligations and interest-bearing investments mergers and acquisitions. However, these enhancement plans are subject to risk from changes in interest and exchange rates. The risks related to interest-bearing investments and borrowings and the availability and cost of appropriate opportunities, competition from other pharmaceutical companies thatmeasures we have taken to help contain them are seeking similar opportunities and our ability to successfully identify, structure and execute transactions, including the ability to satisfy the conditions to closing of announced transactionsdiscussed in the anticipated timeframeAnalysis of Financial Condition, Liquidity, Capital Resources and Market Risk section within MD&A and Note 7E. For additional details on critical accounting estimates and assumptions for our benefit plans, see the Significant Accounting Policies and Application of Critical Accounting Estimates and Assumptions—Benefit Plans section within MD&A andNote 11.
PRODUCT MANUFACTURING, SALES AND MARKETING RISKS
We could encounter difficulties, delays or inefficiencies in our supply chain, product manufacturing and distribution networks, as well as sales or marketing, due to regulatory actions, shut-downs, work stoppages or strikes, approval delays, withdrawals, recalls, penalties, supply disruptions, shortages or stock-outs at all, and integrate acquisitions. Further, while we seek to mitigate risks and liabilities of such 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,our facilities or third-party facilities that we inadequately assess. Legal proceedingsrely on, reputational harm, the impact to our facilities due to health pandemics or regulatory issues often arisenatural or man-made disasters, including as a result of activitiesclimate change, product liability or unanticipated costs. Examples of such difficulties or delays include the inability to increase or maintain production capacity commensurate with demand; challenges related to component materials to maintain supply and/or appropriate quality standards throughout our supply network and/or comply with applicable regulations; inability to supply certain products due to voluntary product recalls; and supply chain disruptions at our facilities or at a supplier or vendor. In addition, we engage contract manufacturers, and, from time to time, our contract manufacturers may face difficulties or are unable to manufacture our products at the necessary quantity or quality levels.
Regulatory agencies periodically inspect our manufacturing facilities, as well as third-party facilities that occurredwe rely on, to evaluate compliance with cGMP or other applicable requirements. Failure to comply with these requirements may subject us to possible legal or regulatory actions, such as warning letters, suspension of manufacturing, seizure of product, injunctions, debarment, product recalls, delays or denials of product approvals, import bans or denials of import certifications.
In 2021, Pfizer recalled all lots of Chantix in the U.S. due to the presence of a nitrosamine, N-nitroso-varenicline, at acquired companies, their partnersor above the FDA interim acceptable intake limit. Regulatory authorities outside the U.S. have issued updated guidance on nitrosamine acceptable intake levels. With this recently issued guidance, which included an updated intake level for N-nitroso-varenicline, we expect to make regulatory submissions in 2024 to potentially enable Chantix to return to market outside the U.S., and our related discussions with FDA are ongoing.

COUNTERFEIT PRODUCTS

A counterfeit medicine is one that has been deliberatelyOur reputation, in-line and fraudulently mislabeled as to its identitypipeline portfolios render our medicines and source. A counterfeit Pfizer medicine, therefore, is one manufactured by someone other than Pfizer, but which appears to be the same as an authentic Pfizer medicine. The prevalence of counterfeit medicines is a significant and growing industry-wide issue due to a variety of factors, including, but not limited to, the following: the widespread use of the Internet, which has greatly facilitated the ease by which counterfeit medicines can be advertised, purchased and delivered to individual patients; the availability of sophisticated technology that makes it easier for counterfeiters to make counterfeit medicines; the growing involvement in the medicine supply chain of under-regulated wholesalers and repackagers; the lack of adequate inspection at certain international postal facilities as counterfeit medicines are increasingly delivered direct to customers in small parcel packages; and the relatively modest risk of penalties faced by counterfeiters compared to the large profits that can be earned by them from the sale of counterfeit medicines. Further, laws against pharmaceutical counterfeiting vary greatly from country to country, and the enforcement of existing law varies greatly from jurisdiction to jurisdiction. For example, in some countries, pharmaceutical counterfeiting is not a crime; in others, it may result in only minimal sanctions. In addition, those involved in the distribution of counterfeit medicines use complex transport routes in order to evade customs controls by disguising the true source of their products.

Pfizer’s global reputation makes its medicinesvaccines prime targets for counterfeiting organizations. Counterfeit medicinescounterfeiters. Counterfeits pose a significant risk to patient health and safety because of the conditions under which they are manufactured—often in unregulated, unlicensed, uninspected, and unsanitary sites—as well as the lack of regulation of their contents. Failure to mitigate thethis threat of counterfeit medicines, which is exacerbated by the complexity of the supply chain, could adversely impact our business, by, among other things,Pfizer’s patients, potentially causing them harm. This situation, in turn, may result in the loss of patient confidence in the Pfizer name and in the integrity of our medicines and vaccines, and potentially resulting inimpact our business through lost sales, product recalls, and an increased threat ofpossible litigation.

The prevalence of counterfeit medicines is an industry-wide issue due to a variety of factors, including the adoption of e-commerce. The increased adoption during the COVID-19 pandemic further exposed consumers to fake prescription treatments via the internet as access to traditional brick and mortar pharmacies or authorized full-service internet pharmacies that offer authentic treatments may have been hindered. The internet exposes patients to greater risk as it is a preferred vehicle for dangerous counterfeit offers and scams that target unsuspecting consumers. Traffic to these generally deceptive pharmacy sites is largely driven by misplaced trust in sophisticated internet retailers and social media offers coupled with the convenience e-commerce affords consumers. Counterfeiters generally target any medicine or vaccine boasting strong demand and we have observed heightened counterfeit and fraud attempts to our internal medicine portfolio, as well as products utilized in the treatment of COVID-19.
We undertake significant effortsconsistently invest in an enterprise-wide strategy to counteract theaggressively combat counterfeit threats associated with counterfeit medicines, including, among other things, working with the FDA and other regulatory authorities and multinational coalitions to combat the counterfeiting of medicines and supporting efforts by law enforcement authorities to prosecute counterfeiters; assessing new and existing technologies to seek to make it more difficult for counterfeiters to copy our products and easier foreducating patients and healthcare providers to distinguish authentic from counterfeit medicines; implementing business practices designed to protect patient health; promoting public policies intended to hinder counterfeiting; working diligently to raise public awareness about the dangersrisks, investing in innovative technologies to detect and disrupt sophisticated internet offers and scams, proactively monitoring and interdicting supply with the help of counterfeit medicines; and working collaboratively with wholesalers, pharmacies, customs offices, and law enforcement, agencies to increase inspection coverage, monitor distribution channels, and improve surveillance of distributorsadvising legislators and repackagers. No assurance can be given, however, thatregulators. However, our efforts and the effortsthose of others willmay not be entirely successful, and the presence of counterfeit medicines may continue to increase.

RISKS RELATED TO GOVERNMENT REGULATION AND LEGAL PROCEEDINGS:

PROCEEDINGS:
PRICING AND REIMBURSEMENT

U.S. and international governmental regulations that mandate price controls andor limitations on patient access to our products, create coverage criteria 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.

In addition to the recent expansion of price controls in the U.S. in the IRA, the adoption of restrictive coverage policies and price controls in new jurisdictions, more restrictive controls in existing jurisdictions or the failure to obtain or maintain timely or adequate coverage and pricing could also adversely impact revenue. We expect pricing pressures and other cost containment measures for drugs and vaccines 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. Pharmaceutical productpressures as a result. We expect to see continued focus by the U.S. Congress and the Biden Administration on regulating pricing isand access to medicine. For example, in August 2022, the drug pricing provisions of the IRA were signed into law, which, among other things, require manufacturers of certain drugs, including Pfizer, to engage in price negotiations with Medicare which will permit the CMS to set a maximum fair price for selected drugs, impose rebates under Medicare Part B and Medicare Part D to penalize price increases that outpace inflation, and replace the Part D coverage gap discount program with a new discounting program. The drug pricing provisions of the IRA began to be implemented in 2022 and implementation efforts are expected to continue over the next several years. In August 2023, the Biden Administration unveiled the first round of medicines subject to enhanced governmentthe Medicare Drug Pricing Negotiation Program, which included Eliquis. CMS will establish a maximum fair price for Eliquis that will be in effect in 2026. That maximum fair price will be required to be offered to all Medicare beneficiaries and public scrutinyto covered entities participating in the 340B Program if lower than the 340B price. Health plans may also require rebates in addition to the maximum fair price for preferred placement on a Medicare plan formulary. The Medicare Drug Price Negotiation Program is currently subject to legal challenges and calls for reform.therefore, the outcome of the 340B Program remains uncertain. We continue to evaluate the impact of the IRA on our business, operations, financial condition and results as the full effect of the IRA on our business and the pharmaceutical industry remains uncertain.
Payors may promote generic drugs and biosimilars more aggressively to generate savings and attempt to stimulate additional price competition. In addition, we expect that consolidation and integration among pharmacy chains, wholesalers and PBMs will increase pricing pressures in the industry. Some states have implemented, and other statesothers are considering, pharmaceutical price controls or patient access constraints or cost cutting under state regulated programs including the Medicaid program, and some states are considering price-control regimes that would applyprogram. State legislatures also have continued to broader segments of their populations that are not Medicaid-eligible.

Pricing pressures have been, and we anticipate will continue to be, amplified by COVID-19 induced budget deficits and focus on pricing for COVID-19 treatments and vaccines.
U.S. HEALTHCARE REFORM/HEALTHCARE LEGISLATIONREGULATION

The U.S. healthcare industry is highly regulated and subject to frequent and substantial changes. Any significant additional efforts at the U.S. federal or state levels to reform the healthcare system by changing the way healthcare is provided or funded could have a material impact on us. For example,additional information on U.S. healthcare regulation, see the ACA was enacted by Congress in March 2010 and established a major expansion of healthcare coverage, financed in part by a number of new rebates, discounts, and taxes that had a significant effect on our expenses and profitability. See the discussion under the Overview of Our Performance, Operating Environment, Strategy and OutlookOur Operating EnvironmentIndustry-Specific ChallengesRegulatory Environment/Pricing and AccessU.S. Healthcare Legislation section in our 2017 Financial Report and in Item 1. Business under the caption Business––Government Regulation and Price Constraints—In the United States. We face uncertainties due to federal legislative and administrative efforts to repeal, substantially modify or invalidate some or all of the provisions of the ACA. The likelihood of such a repeal currently appears low given the recent failure of the Senate’s multiple attempts to repeal various combinations of such ACA provisions. In October 2017, the President signed an Executive Order directing federal agencies to look for ways to authorize more health plans that could be less expensive because the plans would not have to meet all of the ACA’s coverage requirements, and announced that his administration will withhold the cost-sharing subsidies paid to health insurance exchange plans serving low-income enrollees. These and similar actions by the administration are widely expected to lead to fewer Americans having comprehensive ACA-compliant health insurance, even in the absence of a legislative repeal. The revenues generated for Pfizer by the health insurance exchanges under the ACA are minor, so the impact of the recent administration actions is expected to be limited. There is no assurance that any future replacement, modification or repeal of the ACA will not adversely affect our business and financial results, particularly if the legislation reduces incentives for employer-sponsored insurance coverage, and we cannot predict how future federal or state legislative or administrative changes relating to healthcare reform will affect our business.

section.
Other U.S. federal or state legislative or regulatory action and/or policy efforts could adversely affect our business, including, among others, general budget control actions, changes in patent laws, the importation of prescription drugs from outsideto the U.S. at prices that are regulated by foreign governments, revisions to reimbursement of various foreign countries (which is among the U.S. presidential administration’s policy proposals), restrictions on U.S. direct-to-consumer advertising,biopharmaceuticals under government programs that could reference international prices or require new discounts, limitations on interactions with healthcare professionals and other industry stakeholders, or the use of comparative effectiveness methodologies that could be implemented in a manner that focuses primarily on cost differences and minimizes the therapeutic differences among pharmaceutical products and restricts access to innovative medicines.

Any additional reduction of U.S. ENTITLEMENT REFORM

In the U.S., government action to reduce federal spending on entitlement programs beyond the IRA, including Medicare and Medicaid, may affect payment for our products or services provided using our products. The Congressional Budget Office routinely releases options for reducing federal spending, and the December 2016 release includes proposals to cap Medicaid grants to the states, and to require manufacturers to pay a minimum rebate on drugs covered under part D of Medicare for low-income beneficiaries. Significant Medicare reductions could also result if Congress proceeds with certain proposals to convert the Medicare fee-for-service program into a premium support program, or Congress chooses to implement the recommendations made annually by the Medicare Payment Advisory Commission, which are primarily intended to extend the fiscal solvency of the Medicare program. These and anyAny other significant spending reductions or cost controls affecting Medicare, Medicaid or other publicly funded or subsidized health programs that may be implemented could have an adverse impact on our results of operations.

SUBSTANTIAL REGULATION

The IRA will be implemented largely through government guidance and as its effect on Medicare and commercial markets evolve, we will continue to evaluate the potential impacts to our business.
We are subject to extensive, complex, costly and evolving regulation byexpect additional cost containment measures at both the federal and state governmental authoritieslevels as efforts to reduce drug costs continue. Further, commercial payors often follow Medicare coverage policy and payment limitations when setting their own payment rates. Any reduction in cost or other containment measures may similarly be adopted by commercial plans. Coverage policies and reimbursement rates for commercial plans may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products, less favorable coverage policies and reimbursement rates may be implemented in the U.S., principally by the FDA and the DEA, and foreign regulatory authorities. Failure to comply with all applicable regulatory requirements may subject us to operating restrictions and criminal prosecution, monetary penalties and other disciplinary actions, including, sanctions, warning letters, product seizures, recalls, fines, injunctions, suspension, revocation of approvals, or exclusion from future participation in government healthcare programs.

There is also a risk that we may not adequately address existing regulatory agency findings concerning the adequacy of our regulatory compliance processes and systems or implement sustainable processes and procedures to maintain regulatory compliance and to address future regulatory agency findings, should they occur. In addition, there are risks associated with preliminary, early stage or interim data, including the risk that final results of studies for which preliminary, early stage or interim data have been provided and/or additional clinical trials may be different from (including less favorable than) the preliminary, early stage or interim data results and may not support further clinical development of the applicable product candidate or indication. In addition, clinical trial data are subject to differing interpretations and assessments by regulatory authorities. As a result of regulatory interpretations and assessments or other developments that may occur during the review process, or even when we view data as sufficient to supportafter a product is authorized or approved for marketing, a product’s commercial potential could be adversely affected by potential emerging concerns or regulatory decisions regarding or impacting the scope of indicated patient populations, labeling or marketing, manufacturing processes, safety issues and/or effectiveness of aother matters, including decisions relating to emerging developments regarding potential product candidate or a new indication for an in-line product, regulatory authorities may not share our views and may require additional data or may deny approval altogether.

to granting approval, or increased post-approval requirements, such as risk evaluationrequirements. For these and mitigation strategies.other reasons discussed in this Risk Factors section, we may not obtain the approvals we expect within the timeframe we anticipate, or at all.

In addition, failure to put in place adequate controls and/or resources for effective collection, reporting and management of adverse events from clinical trials and post-marketing surveillance, in compliance with current and evolving regulatory requirements could result in risks to patient safety, regulatory actions and risks to product sales.

The FDA, along with other regulatory agencies around the world, has been experiencing a backlog of generic drug applications, which may result in delayed approvals of new generic products. While the FDA is taking steps to address the backlog of pending applications, continued approval delays may be experienced by generic drug applicants over the next few years.

POST-APPROVALPOST-AUTHORIZATION/APPROVAL DATA

As a condition to granting marketing authorization or approval of a product, the FDA may require, a companyor the sponsor may voluntarily agree to conductundertake, post-marketing commitments such as additional clinical trials.trials or other studies. The results generated in these Phase 4 trials have in the past impacted certain of our products and could resultimpact our products in the future, such as by resulting in the loss of marketing approval, changes in product labeling, and/or new or increased concerns about the side effects safety and/or efficacy, of a product.including newly discovered adverse events. Regulatory agencies in countries outside the U.S. often have similar authorityregulations and may impose comparable requirements.requirements, although there are differences between the U.S., the EU and other international regulatory requirements, which may contribute to inconsistency or uncertainty in the marketability of our products across different jurisdictions. Post-marketing studies and clinical trials, whether conducted by us or by others, and whether mandated by regulatory agencies or voluntary,conducted voluntarily, and other emerging data about marketed products, such as adverse event reports, may also adversely affect the availability or commercial potential of our products. Further, the discovery of significant problems withif safety or efficacy concerns are raised about a product similar toin the same class as one of our products, thatthose concerns could implicate (or are perceived to implicate) anthe entire class of productsclass; and this, in turn, could have an adverse effectimpact on the availability or commercial viability of our product(s) as well as other products in the class. The potential regulatory and commercial implications of post-marketing study results typically cannot immediately be determined.
The terms of our EUA for Comirnaty require that we conduct post-observational studies to evaluate the association between the Pfizer-BioNTech COVID-19 Vaccine (Original monovalent), Pfizer-BioNTech COVID-19 Vaccine, Bivalent, and the Pfizer-BioNTech COVID-19 Vaccine (2023-2024 Formula), and a pre-specified list of adverse events of special interest, including myocarditis and pericarditis, along with deaths and hospitalizations, and severe COVID-19. The required study populations include individuals specified in our September 2023 authorization letter (reissued) as well as populations of interest, such as healthcare workers, pregnant women, immunocompromised individuals and subpopulations with specific comorbidities. Additionally, in relation to the FDA approval for Comirnaty, we are required to complete certain postmarketing study requirements and commitments through 2024 and beyond. In the FDA’s revision to the EUA for Paxlovid, the FDA removed the post-authorization requirements as they were addressed as a post-marketing commitment associated with the approval of the affected products. Accordingly, new data aboutPaxlovid NDA. The terms of our products, or products similarPaxlovid EUA had previously required monitoring of a genomic database(s) for the emergence of global viral variants of SARS-CoV-2 and providing reports to our products, could negatively impact demand for our products duethe FDA on a monthly basis summarizing any findings. Also, the FDA required Pfizer to real or perceived side effects or uncertainty regarding efficacy and, in some cases, could result in updated labeling, restrictions on use, product withdrawal or recall.

INTERACTIONS WITH HEALTHCARE PROFESSIONALS AND GOVERNMENT OFFICIALS

Risks and uncertainties apply if we provide something of value to a healthcare professional, other healthcare provider and/or government official. Ifassess the interaction is found to be improper, government enforcement actions and penalties could result. These risks may increase as non-U.S. jurisdictions adopt or increase enforcement efforts of new anti-bribery laws and regulations. Requirements or industry standards in the U.S. and certain jurisdictions abroad that require pharmaceutical manufacturers to track and disclose financial interactions with healthcare professionals and healthcare providers increase government and public scrutiny of such financial interactions.

CHANGES IN LAWS AND ACCOUNTING STANDARDS

Our future results could be adversely affected by changes in interpretations of existing laws and regulations, or changes in laws and regulations, including, among others, changes in accounting standards, taxation requirements (including tax rate changes, new tax laws, changes to existing tax laws and revised tax law and regulatory clarifications and/or interpretations, including changes affecting the taxation by the U.S. of income earned outside the U.S. that may result from pending and possible future proposals, including further clarifications and/or interpretationsactivity of the recently passed Tax Cutsauthorized Paxlovid against any global SARS-CoV-2 variant(s) of interest and Jobs Act), competition laws, privacy lawscomplete certain other analyses and environmental laws in the U.S. and other countries.

LEGAL PROCEEDINGS

MATTERS
We are and certain of our subsidiaries aremay be involved in various legal proceedings, including patent litigation, product liability and other product-related litigation, including personal injury, consumer, off-label promotion, securities, antitrust and breach of contract claims, commercial and other asserted and unasserted matters, environmental, government and tax investigations, employment, tax litigation and other legal proceedings that arise from time to time in the ordinary course of our business. Litigation is inherently unpredictable, and excessive verdicts do occur. Although we believe that our claims and defenses in matters in which we are a defendant are substantial, we have substantial defenses in these matters, wethe past and could in the future incur judgments, enter into settlements of claims or revise our expectations regarding the outcomesoutcome of certain matters, and such developments could have a material adverse effect on our results of operations in the period in which the amounts are accrued and/or our cash flows in the period in which the amounts are paid.

Claims against our patents include challenges to the coverage and/or validity of our patents on various products or processes. Although we believe we have substantial defenses to these challenges with respect to all of our material patents, thereThere can be no assurance as to the outcome of these matters, and a loss in any of these cases could result in a loss of patent protection for the product at issue, which could lead to a significant loss of sales of that product and could materially affect future results of operations.

Like other pharmaceutical companies, weWe are subjectalso involved in government investigations that arise in the ordinary course of our business. There continues to be a significant volume of government investigations and extensive regulation by government agencieslitigation against companies operating in our industry, both in the U.S., other developed markets and multiple emerging marketsaround the world. Government investigations and actions have and could result in which we operate. As a result, we have interactions with government agencies on an ongoing basis.

Our activities relating to the salesales and marketing andactivities, the pricing of our products and other aspects of our business are subject to extensive regulation under the FFDCA, the Medicaid Drug Rebate Program, the FCPA and other federal and state statutes, including those discussed elsewhere in this 2017 Form 10-K, as well as anti-kickback and false claimsthe Anti-Kickback Statute, anti-bribery laws, the False Claims Act, and similar laws in international jurisdictions. In addition to the potential for changes to relevant laws, the compliance and enforcement landscape is informed by government litigation, settlement precedent, advisory opinions, and special fraud alerts. Our approach to certain practices may evolve over time in light of these types of developments.
Requirements or industry standards in the U.S. and certain jurisdictions abroad require pharmaceutical manufacturers to track and disclose financial interactions with healthcare professionals and healthcare providers and can increase government and public scrutiny of such financial interactions. If an interaction is found to be improper, government enforcement actions and penalties could result. Like many companies in our industry, we have from time to timetime-to-time received, and may receive in the future, inquiries and subpoenas and other types of information demands from government authorities, andauthorities. In addition, we have been subject to claims and other actions related to our business activities, brought by governmental authorities, as well as by consumers and private payers.payors. In some instances, we have incurred significant expense, civil payments, fines and other adverse consequences as a result of these claims, actions and inquiries. For example, theseSuch claims, actions and inquiries may relate to alleged failures to accurately interpret or identify or prevent non-compliance with the laws and regulations associated with the dissemination of product information (approved and unapproved), information, potentially resulting in government enforcement action and damage to our reputation.reputational damage. This risk may be heightened by digital marketing, including social media, mobile applications and blogger outreach.

ENVIRONMENTAL CLAIMS AND PROCEEDINGS

In connection with the resolution of a U.S. government investigation concerning independent copay assistance organizations that provide financial assistance to Medicare patients, in 2018, we entered into a Corporate Integrity Agreement (CIA) with the Office of the Inspector General of the HHS (OIG), which expired in May 2023. Pfizer submitted its final annual report and is awaiting a response from the OIG.

RISKS RELATED TO INTELLECTUAL PROPERTY,: TECHNOLOGY AND SECURITY:

PATENTINTELLECTUAL PROPERTY PROTECTION

Our long-term 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.all, and any term adjustments related to patent office delays in obtaining a patent may be reduced or eliminated entirely due to risks associated with changes in law relating to patent terms. In addition, our issued patents may not contain claims sufficiently broad to protect us against thirdclaims 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 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. We may be subject to challenges by third parties regardinglaws, and our intellectual property, including, among others, claims regarding validity, enforceability, scope and effective term.


Pfizer Inc.2017 Form 10-K18

TABLE OF CONTENTS

Our ability to enforce our patents also depends on the laws of individual countries and each country’s practice with respect tocountry, its enforcement of intellectual property rights,practices, and the extent to which certain sovereigns may seek tocountries engage in policies or practices that weaken a policy of routine compulsory licensing of pharmaceuticalcountry’s intellectual property asframework (e.g., laws or regulations that promote or provide broad discretion to issue a result of local political pressure or in the case of national emergencies.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 increasingly employing aggressive strategies, such as “at risk”“at-risk” launches tothat 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,payors, 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 byin such proceedings, generic or competitivebiosimilar products could be introduced into the market resulting in the erosion of sales of our existing products. For example, several of the patents in our pneumococcal vaccine portfolio have been challenged in inter partes review and post-grant reviewadditional information, including information regarding certain legal proceedings in the U.S. The invalidation of these patents could potentially allow a competitor pneumococcal vaccine into the marketplace.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, including because such agreements expire or are terminated, our operating results and financial condition could be materially adversely affected.

Likewise, in the U.S. and other countries, weWe currently hold issued 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 trademark rights, our business could be materially adversely affected.rights. We actively 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 employment, engagement or other relationship.relationship with us. Despite these efforts and precautions, we may be unable to prevent a third partythird-party from copying or otherwise obtaining and using our trade secrets or our other intellectual property without authorization, and legal remedies in some countries 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.

THIRD PARTYTHIRD-PARTY INTELLECTUAL PROPERTY CLAIMS

A properly functioning intellectual property regime is essential to our business model. We are committed to respecting the valid intellectual property rights of other companies, but the patent granting process is imperfect. Accordingly, the pursuit of valid business opportunities may require us to challenge intellectual property rights held by other companiesothers that we believe were improperly granted. Suchgranted, including challenges may includethrough negotiation and litigation, whichand such challenges may not always be successful.

Part of our EH business depends upon successfully identifying generic pharmaceutical product and biosimilar opportunities and launching products to take advantage of those opportunities, which may involve litigation, associated costs and time delays, and may ultimately not be successful. These opportunities may arise in situations where patent protection of equivalent branded products has expired where patents haveor been declared invalid, or where products do not infringe the patents of others. To achieve a “first-to-market” or early market position for generic pharmaceutical products and biosimilars,In some circumstances we may take action, such as litigation, asserting that our products do not infringe patents of existing products or that those patents are invalid or unenforceable.

Third parties may claim that our products infringe one or more patents owned or controlled by the third party.them. Claims of intellectual property infringement can be costly and time-consuming to resolve, may delay or prevent product launches, and may result in significant damages.royalty payments or damages or potential licensing agreements. For example, our R&D in a therapeutic area may not be first and another company or entity may have obtained relevant patents before us. We are involved in patent-related disputes with third parties over our attempts to market generic pharmaceutical products, including related to Abrysvo, Comirnaty and biosimilars.Paxlovid. As we expand our mRNA portfolio, patent-related disputes may increase. Once we have final regulatory approval of the related generic pharmaceuticals products, or biosimilars, we may decide to commercially market these products even though associated legal proceedings (including any appeals) have not been resolved (i.e., “at-risk” launch). If one of our marketed products (or a product of our

Pfizer Inc.2023 Form 10-K22


collaboration/licensing partners to which we have licenses or co-promotion rights) is found to infringe valid patent rights of a third party, such third party may be awarded significant damages or royalty payments, or we may be prevented from further sales of that product. Such damages may be enhanced as much as three-fold in the event thatif we or one of our subsidiaries like Hospira, is found to have willfully infringed valid patent rights of a third party. Any of these adverse consequences could have a material adverse effect on our profitability and financial condition.

Significant disruptions of information technologyIT systems or breaches of information security could adversely affect our businesses.business. We extensively rely to a large extent upon sophisticated information technologyIT systems (including cloud services) to operate our businesses. In the ordinary course of business, webusiness. We produce, collect, process, store and transmit large amounts of confidential information (including but not limited to, personal information and intellectual property), and we deploy and operate an array of technical and procedural controls to maintain the confidentiality, integrity and integrityavailability of such confidential information. We alsodevelop and operate digital systems to engage patients, healthcare providers, governments, payors and supply chain partners to conduct business and deliver medicines, digital diagnostics, clinical trials and digital therapies. Such systems include mobile applications, wearable devices, internet websites and other digital technologies that may be targets of attack. We have outsourced significant elements of our operations, to third parties, including significant elements of our information technologyIT infrastructure and, as a result, we are managing many independent vendormanage relationships with third partiesmany third-party providers who may or could have access to our confidential information. We rely on technology developed, supplied and/or maintained by third-parties that may make us vulnerable to “supply chain” style cyber-attacks. Further, technology and security vulnerabilities of acquisitions, business partners or third-party providers may not be identified during due diligence or soon enough to mitigate exploitation. The size and complexity of our information technologyIT and information security systems, and those of our third-party vendors with whom we contractproviders (and the large amounts of confidential information that is present on them), make such systems potentially vulnerable to service interruptions or to security breaches from inadvertent or intentional actions by, but not limited to, our employees, contingent workers, service providers, business partners, customers or vendors, or from attacks by malicious third parties.attackers. As a global pharmaceutical company, our systems and assets are the target of frequent cyber-attacks. Such attackscyber-attacks are of ever-increasing levels of sophistication, including the use of adversarial artificial intelligence techniques, and are made by groups and individuals with a wide range of motives (including, but not limited to, industrial espionage)espionage, extortion, property destruction and personal information theft) and expertise, including, but not limited to, organized criminal groups, “hacktivists,” nation states, employees, business partners and others. As a global pharmaceutical company, our systems are subject to frequent attacks. Due to the nature of some of these attacks, there is a risk that they may remain undetected for a period of time. While we have invested in the protection of data and information technology, there can be no assurance thatIT and develop and maintain systems and controls, our efforts, willlike those of other similar companies, have not always and may not in the future prevent service interruptions, extortion, theft of confidential, personal or security breaches.proprietary information, compromise of data integrity or unauthorized information disclosure. Any suchtechnology service interruption or breach of our systems could adversely affect our business operations and/or result in the loss of critical or sensitivepersonal data, confidential information or intellectual property,property. Such incidents could require disclosure to government authorities and/or regulators and could require notification to impacted individuals and any incident could result in financial, legal, business and reputational harm to us. We maintain cyber liability insurance; however, this insurance may not be sufficient to cover the financial, legal, business or reputational losses that may result from an interruption or breach of our systems.

Artificial intelligence-based software is increasingly being used in the biopharmaceutical and global healthcare industries. As with many developing technologies, artificial intelligence-based software presents risks and challenges. For example, algorithms may be flawed; data sets may be insufficient, of poor quality, or contain biased information; and inappropriate or controversial data practices by data scientists, engineers, and end-users could impair results. If the analyses that artificial intelligence-based applications assist in producing are deficient or inaccurate, we could be subjected to competitive harm, potential legal liability and brand or reputational harm. Furthermore, use of artificial intelligence-based software may lead to the release of confidential information which may impact our ability to realize the benefits of our intellectual property.
GENERAL RISKS RELATED TO OUR
BUSINESS DEVELOPMENT ACTIVITIES AND STRATEGIC TRANSACTIONS:GOALS

STRATEGIC ACQUISITIONS

We have established significant growth goals, which we plan to achieve, in part, by not only advancing our own product pipelines and maximizing the value of our existing products, but also through various forms of business development activities, which can include alliances, licenses, JVs, collaborations, equity- or debt-based investments, dispositions, divestments, mergers and acquisitions. Our recent acquisition of Seagen is part of that growth plan. We view our business development activity as an enabler of our strategies and seek to generate growth by pursuing opportunities and transactions that have the potential to strengthen our business and our capabilities. The success of our acquisitionsbusiness development activities is dependent on the availability and accurate evaluation of Hospira, Anacor, Medivationappropriate opportunities, competition from others that are seeking similar opportunities and AstraZeneca’s small molecule anti-infectivesour ability to successfully identify, structure and execute transactions, including the ability to satisfy closing conditions in the anticipated timeframes or at all, and our ability to successfully integrate acquired businesses and develop and commercialize acquired products. Pursuing, executing and consummating these transactions may require substantial investment, which may require us to obtain additional equity or debt financing, which has in the past and could in the future result in increased leverage and/or a downgrade of our credit ratings and could limit our ability to obtain future financing. We have incurred substantial indebtedness to fund our recent acquisition of Seagen. We financed a portion of the transaction with the proceeds from the $31 billion of long-term debt issued in May 2023, plus $8 billion in additional short-term indebtedness issued prior to the acquisition. The amount of debt that we have incurred could have significant consequences including, among other things, reducing our operating or financial flexibility, requiring a portion of our cash flow from operations to make interest payments and reducing the cash flow available to fund capital expenditures and other corporate purposes and to grow our business. To the extent we incur additional indebtedness or interest rates increase, these risks could increase further.
The success of our business will depend, in large part,development transactions, including our recent acquisition of Seagen, depends on our ability to realize the anticipated benefits of these transactions and is subject to numerous risks and uncertainties, many of which are outside of our control. Unsuccessful clinical trials, regulatory hurdles and commercialization challenges, among other factors, may adversely impact revenue and income contribution from combiningbusiness development transactions, including from acquired products and businesses. We may fail to generate expected revenue growth for our existing products, product pipeline and contribution from these transactions or from acquired products or businesses with Pfizer. We, for example,or we may fail to achieve anticipated cost savings, anticipatedsuch as those expected with the acquisition of Hospira, or such cost savingsrespect to Seagen, within the expected time frame. frames or at all, which may impact our ability to meet our growth objectives. In certain transactions, we may agree to provide certain transition services for an extended period of time, which may divert our focus and resources that would otherwise be invested into maintaining or growing our business. Similarly, the accretive impact anticipated from the acquisitions of Hospira, Anacor and Medivationcertain transactions may not be realized or may be delayed. Integration of theseacquired products or businesses may result in the loss of key employees, the disruption of ongoing business, including third-party relationships, or inconsistencies in standards, controls, procedures and policies. We alsoFurther, while we seek to mitigate risks and liabilities through, among other things, due diligence, we may failbe exposed to generaterisks and liabilities as a result of business development transactions. There is no assurance that we will be able to acquire attractive businesses or enter into strategic business relationships on favorable terms ahead of our competitors, or that such acquisitions or strategic business development relationships will be accretive to earnings or improve our competitive position.

PANDEMICS
Pandemics, such as the COVID-19 pandemic, have impacted and product candidates also may be constrained by developments outsidein the future impact our business, operations and financial condition and results. Related risks and challenges for our business include, among others: uncertainty regarding the severity and duration of a pandemic; impacts to business operations; decreased demand for certain of our control. Unsuccessfulproducts; increased costs of doing business; 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; evolving macroeconomic factors and conditions, including general economic uncertainty, unemployment rates and recessionary pressures; changes in labor markets, including challenges related to our human capital and talent development; unknown consequences on our business performance and initiatives stemming from the substantial investment of time and other resources to any potential pandemic response; increased difficulty and uncertainty regarding predicting or estimating future performance; pace of post-pandemic recovery, disruption and volatility within the financial or credit markets; and our financial performance in general.
COVID-19
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, market share and commercial markets for our current or future 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 or our COVID-19 products on our business, operations and financial condition and results due to the uncertainty of future developments. COVID-19 or our COVID-19 products 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:

CLIMATE CHANGE AND SUSTAINABILITY
Pfizer is subject to transitional and physical risks related to climate change. Transitional risks include, for example, has experienced manufacturing disruptionsa disorderly global transition away from fossil fuels that may result in increased energy prices; customer preference for low or no-carbon products; stakeholder pressure to decarbonize assets; or new legal or regulatory requirements that result in new or expanded carbon pricing, taxes, restrictions on greenhouse gas emissions, and substantial regulatory scrutiny dueincreased greenhouse gas disclosure and transparency. These risks could increase operating costs, including the cost of our electricity and energy use, or otherwise increase compliance costs. Physical risks to quality issues, including receiving a warning letter from the FDA in February 2017 communicating the FDAs view that certain violationsour operations include water stress and drought; flooding and storm surge; wildfires; extreme temperatures and storms, which could impact pharmaceutical production, increase costs, or disrupt supply chains of cGMP regulations exist at Hospirasmedicines for patients. For example, our manufacturing facility in McPherson, Kansas. Manufacturing problems, as well as any corrective actions and their operational implementation, could adversely impactRocky Mount, NC was damaged by a tornado in July 2023. While manufacturing has resumed, the revenue we generate from products acquired from Hospira and result in substantial unanticipated costs.supply of medicines impacted by the tornado is expected to be affected through 2024. For additional information,details on the impact of the tornado in Rocky Mount, NC, see the Overview of Our Performance, Operating Environment, Strategy and Outlook––Our BusinessProduct Manufacturing Operating Environmentsection within MD&A. Our supply chain is subject to these same transitional and physical risks and would likely pass along any increased costs to us.
In June 2022, Pfizer established our fourth consecutive greenhouse gas reduction goal with new near- and long-term targets to achieve the Science Based Target Initiative’s voluntary Net-Zero Standard by 2040. While we are working to develop and implement emission reduction plans to achieve our voluntary climate goals, various factors, including the long time horizons and commercial availability of new technologies to enable the emission reductions, in our 2017 Financial Report. Also, the success of our acquisition of Medivation depends ontime and scale needed, may present inherent risk in our ability to grow revenuesmeet these goals. Additionally, success may depend on the actions of governments and third parties and may require, among other things, significant capital investment; R&D; and government policies and incentives to foster innovation and reduce costs of technologies that may not currently exist or be available at scale.
Governmental authorities, non-governmental organizations, customers, investors, employees, and other stakeholders are increasingly sensitive to ESG matters, such as equitable access to medicines and vaccines, product quality and safety, diversity, equity and inclusion, environmental stewardship, support for Xtandilocal communities, value chain environmental and expand Xtandi intosocial due diligence, corporate governance and transparency, and addressing human capital factors in our operations. In addition, governments and the non-metastatic castration-resistant prostate cancer setting.

STRATEGIC ALTERNATIVES FOR PFIZER CONSUMER HEALTHCARE

In October 2017, we announced planspublic expect companies like us to review a range of strategic alternatives forreport on our Consumer Healthcare business including a full or partial separation of the Consumer Healthcare business from Pfizer through a spin-off, sale or other transaction,practices with respect to human rights, responsible sourcing and environmental impact, as well as the possibilityactions of our third-party contractors and suppliers around the world. This focus on ESG matters may lead to new expectations or requirements that we may ultimately determinecould result in increased costs associated with research, development, manufacture, or distribution of our products. Our ability to retain the business. We expect that a decision regarding strategic alternatives for the Consumer Healthcare business would be made in 2018.

We will incur expenses in connection with the review of strategic alternatives and are likely to incur significant expenses if we determine to move forward with any strategic alternatives. Our future results maycompete could also be affected by the impact ofchanging customer preferences and requirements, such as growing demand for companies to establish validated Net Zero targets or offer more sustainable products. While we strive to improve our reviewESG performance and meet our voluntary goals, if applicable, consummation of strategic alternativeswe do not meet, or are perceived not to meet, our goals or other stakeholder expectations in key ESG areas, we risk negative stakeholder reaction, including from proxy advisory services, as well as damage to our brand and reputation, reduced demand for our Consumer Healthcare business, which are subject to certain risks and uncertainties, including, amongproducts or other things, the ability to realize the anticipated benefits of any strategic alternatives we may pursue, the potential for disruption tonegative impacts on our business and diversionoperations. While we monitor a broad range of management’s attention fromESG matters, we cannot be certain that we will manage such matters successfully, or that we will successfully meet the expectations of investors, employees, consumers, governments and other aspectsstakeholders.

OTHER RISKS:

THE GLOBAL ECONOMIC ENVIRONMENT

Like all businesses, we are exposed to both global and industry-specific economic conditions. Governments, corporations and insurance companies, which provide insurance benefits to patients, have implemented increases in cost-sharing and restrictions on access to medicines, potentially causing patients to switch to generic or biosimilar products, delay treatments, skip doses or use less effective treatments. Government financing pressures can lead to negative pricing pressure in various markets where governments take an active role in setting prices, access criteria (e.g., through public or private health technology assessments), or other means of cost control. Examples include Europe, Japan, China, Canada, South Korea and a number of other international markets. The U.S. continues to maintain competitive insurance markets, but has also seen significant increases in patient cost-sharing and growing government influence as government programs continue to grow as a source of coverage.

The global economic environment has not had, nor do we anticipate that it will have, a material impact on our liquidity or capital resources. Due to our significant operating cash flows, financial assets, access to capital markets and available lines of credit and revolving credit agreements, we continue to believe that we have, and will maintain, the ability to meet our liquidity needs for the foreseeable future. We monitor our liquidity position continuously in the face of evolving economic conditions, but there can be no guarantee that changes in global financial markets and global economic conditions will not affect our liquidity or capital resources or impact our ability to obtain financing in the future.

We continue to monitor credit, capital restrictions and economic situations in volatile regions and markets, especially where the ability to obtain U.S. dollars for local currency is unpredictable and challenging. We cannot predict the likelihood of future changes in these economic conditions, or what impact they may have on our results of operations, financial condition or business.

In addition, given that a significant portion of our business is conducted in the EU, including the U.K., the formal change in the relationship between the U.K. and the EU caused by Brexit may pose certain implications to our research, commercial and general business operations in the U.K. and the EU, including the approval and supply of our products. Details on how Brexit will be executed and the impact on the remaining EU countries will dictate how and whether the broader EU will be impacted and what the resulting impact on our business may be. For additional information, see the Analysis of Financial Condition, Liquidity, and Capital ResourcesGlobal Economic ConditionsU.K. and Market Risksection in our 2017 Financial Report.within MD&A.

We also continueOur pension benefit obligations and postretirement benefit obligations are subject to monitor the global trade environment and potential trade conflicts. If trade restrictions reduce global economic activity, or if other factors lead to a general economic downturn, potential impacts could include declining sales; increased costs; volatility in foreign exchange rates; a declinefrom changes in the fair value of our financial assetsequity investments and pension plan investments; required increases of our pension funding obligations; increased government cost control efforts; delays or failuresother investment risk in the performance of customers, suppliers, and other third parties on whom we may depend for the performance of our business; and the risk that our allowance for doubtful accounts may not be adequate.

FOREIGN EXCHANGE AND INTEREST RATE RISK

Significant portions of our revenues, costs and expenses,assets funding these plans, as well as our substantial international net assets, are exposed to changes in foreign exchange rates. 50% of our total 2017 revenues were derived from international operations, including 21% from Europe and 20% from Japan and the rest of Asia. As we operate in multiple foreign currencies, includingappropriate discount rate. See the euro, the Japanese yen, the Chinese renminbi, the U.K. pound, the Canadian dollar and approximately 100 other currencies, changes in those currencies relative to the U.S. dollar will impact our revenues and expenses. If the U.S. dollar were to weaken against another currency, assuming all other variables remained constant, our revenues would increase, having a positive impact on earnings, and our overall expenses would increase, having a negative impact on earnings. Conversely, if the U.S. dollar were to strengthen against another currency, assuming all other variables remained constant, our revenues would decrease, having a negative impact on earnings, and our overall expenses would decrease, having a positive impact on earnings. Therefore, significant changes in foreign exchange rates can impact our results and our financial guidance.

The impact of possible currency devaluations in countries experiencing high inflation rates or significant exchange fluctuations can impact our results and financial guidance. For additional information about our exposure to foreign currency risk, see the Overview of Our Performance, Operating Environment, Strategy and Outlook––Our Financial Guidance for 2018 and Analysis of Financial Condition, Liquidity and Capital Resources sections in our 2017 Financial Report.

In addition, our interest-bearing investments and borrowings, and our pension benefit obligations, net, and our postretirement benefit obligations, net, are subject to risk from changes in interest rates and foreign exchange rates. These risks and the measures we have taken to help contain them are discussed in the Forward-Looking Information and Factors That May Affect Future ResultsFinancial Risk Management section in our 2017 Financial Report.

NONORDINARY EVENTS
Growth in costs and expenses, changes in product segment and geographic mix and the impact of acquisitions, divestitures, restructurings, internal reorganizations, product withdrawals, recalls and other unusual events that could result from evolving business strategies, evaluation of asset realization and organizational restructuring could adversely affect future results. Such risks and uncertainties include, in particular, our ability to realize the projected benefits of (i) our cost-reduction and productivity initiatives; (ii)initiatives, including our internal separation of our commercial operations into our current operating structure; (iii) anyenterprise-wide cost realignment program, other corporate strategic initiatives such as our evaluation of strategic alternatives for our Consumer Healthcare business; and (iv) any acquisitions, divestitures or other initiatives, as well as potential disruption of ongoing business, such as potential impacts on our acquisitionsability to deliver on our pipeline as planned. Additionally, as a result of Hospira, Anacor, Medivationthese initiatives, we may experience a loss of continuity, loss of accumulated knowledge or intellectual property and/or inefficiency, adverse effects on employee morale, loss of key employees and/or other retention issues during transitional periods. Reorganizations and AstraZeneca’s small molecule anti-infectivesrestructurings can require a significant amount of time and focus, which may divert attention from operating and growing our business.

If we fail to achieve some or all of the expected benefits of restructuring, it could have a material adverse effect on our competitive position, business, financial condition, results of operations and cash flows.
INTANGIBLE ASSETS, GOODWILL AND EQUITY-METHOD INVESTMENTS

Our consolidated balance sheet contains significant amounts of intangible assets, including IPR&D and goodwill. For IPR&D assets, the risk of failure is significant, and there can be no certainty that these assets ultimately will yield successful products. The nature of the biopharmaceutical business is high-risk and requires that we invest in a large number of projects in an effort to achieve a successful portfolio of approved products. Our ability to realize value on these significant investments is often contingent upon, among other things, regulatory approvals and market acceptance. As such, we expect that many of these IPR&D assets willmay become impaired andand/or be written off at some time in the future. future if the associated R&D effort is abandoned or is curtailed. See Note 4for a discussion of recent impairments of IPR&D assets. For goodwill, all reporting units can confront events and circumstances that can lead to a goodwill impairment charge (suchsuch as, among other things, unanticipated competition, an adverse action or assessment by a regulator, a significant adverse change in legal matters or in the business climate and/or a failure to replace the contributions of products that lose exclusivity). Any such charge may be significant.exclusivity. Our other intangible assets, including developed technology rights and brands, face similar risks for impairment and charges related to such assets may be significant as well.

ITEM 1C.CYBERSECURITY
Managing cybersecurity risk is a crucial part of our overall strategy for safely operating our business. We incorporate cybersecurity practices into our Enterprise Risk Management (ERM) approach, which is subject to oversight by our BOD. Our cybersecurity policies and practices are aligned with relevant industry standards.
Consistent with our overall ERM program and practices, our cybersecurity program includes:
Vigilance: We maintain a global cybersecurity operation that endeavors to detect, prevent, contain, and respond to cybersecurity threats and incidents in a prompt and effective manner with the goal of minimizing business disruptions.
External Collaboration: We collaborate with public and private entities, including intelligence and law enforcement agencies, industry groups and third-party service providers to identify, assess and mitigate cybersecurity risks.
Systems Safeguards: We deploy technical safeguards that are designed to protect our information systems, products, operations and sensitive information from cybersecurity threats. These include firewalls, intrusion prevention and detection systems, disaster recovery capabilities, malware and ransomware prevention, access controls and data protection. We continuously conduct vulnerability assessments to identify new risks and periodically test the efficacy of our safeguards through both internal and external penetration tests.
Education: We provide periodic training for all personnel regarding cybersecurity threats, with such training appropriate to the roles, responsibilities and access of the worldrelevant Company personnel. Our policies require all workers to report any real or suspected cybersecurity events.
Supplier Ecosystem Management: We extend our cybersecurity management control expectations to our supply chain ecosystem, as applicable. This includes identifying cybersecurity risks presented by third parties.
Incident Response Planning: We have established, and related U.S. military action overseas.maintain and periodically test, incident response plans that direct our response to cybersecurity events and incidents. Such plans include the protocol by which material incidents would be communicated to executive management, our BOD, external regulators and shareholders.


Enterprise-Wide Coordination: We engage experts from across the Company to identify emerging risks and respond to cybersecurity threats. This cross-functional approach includes personnel from our R&D, manufacturing, commercial, technology, legal, compliance, internal audit and other business functions.

Pfizer Inc.20172023 Form 10-K2226

TABLE OF CONTENTS

Governance: Our BOD’s oversight of cybersecurity risk management is led by the Audit Committee, which oversees our ERM program. Cybersecurity threats, risks and mitigation are periodically reviewed by the Audit Committee and such reviews include both internal and independent assessment of risks, controls and effectiveness.
Our risk assessment efforts have indicated that we are a target for theft of intellectual property, financial resources, personal information, and trade secrets from a wide range of actors including nation states, organized crime, malicious insiders and activists. The impacts of attacks, abuse and misuse of Pfizer’s systems and information include, without limitation, loss of assets, operational disruption and damage to Pfizer’s reputation.
A key element of managing cybersecurity risk is the ongoing assessment and testing of our processes and practices through auditing, assessments, drills and other exercises focused on evaluating the sufficiency and effectiveness of our risk mitigation. We regularly engage third parties to perform assessments of our cybersecurity measures, including information security maturity assessments and independent reviews of our information security control environment and operating effectiveness. Certain results of such assessments and reviews are reported to the Audit Committee and the BOD, as appropriate, and we make adjustments to our cybersecurity processes and practices as necessary based on the information provided by the third-party assessments and reviews.
The Audit Committee oversees cybersecurity risk management, including the policies, processes and practices that management implements to prevent, detect and address risks from cybersecurity threats. The Audit Committee receives regular briefings on cybersecurity risks and risk management practices, including, for example, recent developments in the external cybersecurity threat landscape, evolving standards, vulnerability assessments, third-party and independent reviews, technological trends and considerations arising from our supplier ecosystem. The Audit Committee may also promptly receive information regarding any material cybersecurity incident that may occur, including any ongoing updates regarding the same. The Audit Committee periodically discusses our approach to cybersecurity risk management with our Chief Information Security Officer (CISO).
Our CISO is a member of our management team who is principally responsible for overseeing our cybersecurity risk management program, in partnership with other business leaders across the Company. The CISO works in coordination with other members of the management team, including, among others, the Chief Digital Officer, the Chief Financial Officer, the Chief Compliance and Risk Officer and the General Counsel and their designees. We believe our business leaders have the appropriate expertise, background and depth of experience to manage risks arising from cybersecurity threats.
Our CISO, along with leaders from our privacy and corporate compliance functions, collaborate to implement a program designed to manage our exposure to cybersecurity risks and to promptly respond to cybersecurity incidents. Prompt response to incidents is delivered by multi-disciplinary teams in accordance with our incident response plan. Through ongoing communications with these teams during incidents, the CISO monitors the triage, mitigation and remediation of cybersecurity incidents, and reports such incidents to executive management, the Audit Committee and other Pfizer colleagues in accordance with our cybersecurity policies and procedures, as is appropriate.
As of the date of this Form 10-K, we are not aware of any cybersecurity incidents that have materially affected or are reasonably likely to materially affect the Company, including our business strategy, results of operations, or financial condition at this time. For further discussion of the risks associated with cybersecurity incidents, see the Item 1A. Risk Factors—Information Technology and Security section in this Form 10-K.

References to operational variances pertain to period-over-period changes that exclude the impact of foreign exchange rates. Although foreign exchange rate changes are part of our business, they are not within our control and since they can mask positive or negative trends in the business, we believe presenting operational variances excluding these foreign exchange changes provides useful information to evaluate our results.
Our Business and Strategy––Pfizer Inc. is a research-based, global biopharmaceutical company. We apply science and our global resources to bring therapies to people that extend and significantly improve their lives. See the Item 1. Business––About Pfizersection. As a science-driven global biopharmaceutical company, we remain focused on advancing our pipeline, supporting our marketed brands and deploying capital responsibly, with a focus on initiatives that can help contribute to our long-term revenue and future growth. Most of our revenues come from the discussion undermanufacture and sale of biopharmaceutical products. We believe that our medicines and vaccines provide significant value for healthcare providers and patients and continuously evaluate how we can best collaborate with patients, physicians and payors to support and expand patient access to reliable, affordable healthcare around the heading Financial Reviewworld. In addition, we continually seek to expand and broaden our product portfolio offerings through prioritized development of our pipeline and business development opportunities targeted at critical unmet patient needs. As a result, our commercial organizational structure and R&D operations are critical to the successful execution of our business strategy. Our ability to fulfill our purpose, Breakthroughs that change patients’ lives, remains a core focus and underscores our commitment to addressing the needs of society to help sustain long-term value creation for all stakeholders. Our 2024 key priorities are:
Achieve world-class oncology leadership
Deliver next wave of pipeline innovation
Maximize performance of our new products
Expand margins by realigning our cost base
Allocate capital to enhance shareholder value

Pfizer Inc.2023 Form 10-K30


In 2023, we managed our commercial operations through a global structure consisting of two operating segments: Biopharma and Business Innovation. Biopharma was the only reportable segment. See Note 1Aand the Item 1. Business––Commercial Operationssection.
In December 2023, we completed our acquisition of Seagen. At the beginning of 2024, we made changes in our 2017 Financial Report.commercial organization that went into effect on January 1, 2024 to incorporate Seagen and improve focus, speed and execution. Specifically, within our Biopharma reportable segment we created:

the Pfizer Oncology Division, which brings together U.S. oncology commercial operations from both Pfizer and Seagen and is led by the Chief Oncology Officer, Executive Vice President, who also leads Pfizer’s newly combined global oncology R&D operations;
the Pfizer U.S. Commercial Division, which focuses on the commercialization of non-oncology products in the U.S. and is led by the Chief U.S. Commercial Officer, Executive Vice President; and
the Pfizer International Commercial Division, which focuses on the commercialization of Pfizer’s entire product portfolio outside the U.S. and is led by the Chief International Commercial Officer, Executive Vice President.
In the fourth quarter of 2022, we began taking steps through our Transforming to a More Focused Company restructuring program to optimize our end-to-end R&D operations to reduce costs and cycle times as well as to further prioritize our internal R&D portfolio in areas where our capabilities are differentiated while increasing external innovation efforts to leverage an expanding and productive biotech sector. Beginning in July 2023, in consideration of planned future investments in oncology, including the acquisition of Seagen on December 14, 2023, we reorganized our R&D platform operations. See Note 17A. In the fourth quarter of 2023, we announced that we launched a multi-year, enterprise-wide cost realignment program that aims to realign our costs with our longer-term revenue expectations. See Note 3. For a description of savings related to these programs, see the Costs and Expenses––Restructuring Charges and Other Costs Associated with Acquisitions and Cost-Reduction/Productivity Initiativessection within MD&A.
R&D: We believe we have a strong pipeline and are well-positioned for future growth. R&D is at the heart of fulfilling our purpose to deliver breakthroughs that change patients’ lives as we work to translate advanced science and technologies into the medicines and vaccines that may be the most impactful for patients. Innovation, drug discovery and development are critical to our success. In addition to discovering and developing new products, our R&D efforts seek to add value to our existing products by improving their effectiveness and ease of dosing and by discovering potential new indications. See the Item 1. BusinessResearch and Developmentsection for our R&D priorities and strategy.
We seek to leverage a strong pipeline, organize around expected operational growth drivers and capitalize on trends creating long-term growth opportunities, including:
an aging global population that is generating increased demand for innovative medicines and vaccines that address patients’ unmet needs; and
advances in both biological science and platform technologies that are enhancing the delivery of breakthrough new medicines and vaccines.
Our Business Development Initiatives––We are committed to strategically capitalizing on growth opportunities, primarily by advancing our own product pipeline and maximizing the value of our existing products, but also through various business development activities. We view our business development activity as an enabler of our strategies and seek to generate growth by pursuing opportunities and transactions that have the potential to strengthen our business and our capabilities. We assess our business, assets and scientific capabilities/portfolio as part of our regular, ongoing portfolio review process and also continue to consider business development activities that will help advance our business strategy. For a discussion of recent significant business development activities, see Note 2.
Our 2023 Performance
Total Revenues––Total revenues decreased $41.8 billion, or 42%, to $58.5 billion in 2023 from $100.3 billion in 2022, reflecting an operational decrease of $40.8 billion, or 41%, as well as an unfavorable impact of foreign exchange of $1.0 billion, or 1%. The operational decrease was primarily driven by significant declines in revenues from Comirnaty and Paxlovid, including a $3.5 billion non-cash revenue reversal for Paxlovid recorded in the fourth quarter of 2023. Excluding contributions from Comirnaty and Paxlovid, Total revenues increased 7% operationally, reflecting an increase in revenues from Nurtec ODT/Vydura and Oxbryta; revenues from Abrysvo, primarily driven by the launch of the older adult indication in the U.S.; as well as continued growth from the Vyndaqel family and Eliquis; partially offset by a decline in Ibrance.
The following chart outlines the components of the net change in Total revenues:

Pfizer Inc.
ITEM 7A.2023 Form 10-KQUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK31



Information requiredWhile royalty income through December 31, 2023 has been recorded in Other Income/(Deductions)—net, we will begin reporting such royalty income in Total revenues beginning in 2024 and will restate prior periods for consistency with our 2024 presentation. Additionally, we will no longer record royalties from U.S. sales of Bavencio, as we have irrevocably chosen to donate the right to such royalties to the American Association for Cancer Research.
Income from Continuing Operations Before Provision/(Benefit) for Taxes on Income––The decrease in Income from continuing operations before provision/(benefit) for taxes on income of $33.7 billion, to $1.1 billion in 2023 from $34.7 billion in 2022, was primarily attributable to (i) lower revenues, (ii) higher intangible asset impairment charges, and (iii) increases in Restructuring charges and certain acquisition-related costs, Amortization of intangible assets, and Selling, informational and administrative expenses, partially offset by this item(iv) a decrease in Cost of sales and (v) net gains on equity securities in 2023 versus net losses on equity securities in 2022.
SeetheAnalysis of the Consolidated Statements of Income section within MD&A and Note 4. For information on our tax provision and effective tax rate, see the Provision/(Benefit) for Taxes on Income section within MD&A and Note 5.
Our Operating Environment––We, like other businesses in our industry, are subject to certain industry-specific challenges. These include, among others, the topics listed below. See also the Item 1. Business––Government Regulation and Price Constraints and Item 1A. Risk Factorssections.
Regulatory Environment––Pipeline Productivity––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. As a result, we devote considerable resources to our R&D activities which, while essential to our growth, incorporate a high degree of risk and cost, including whether a particular product candidate or new indication for an in-line product will achieve the desired clinical endpoint or safety profile, will be approved by regulators or will be successful commercially. Clinical trials are conducted to determine, among other things, whether an investigational drug, vaccine or device is incorporated by referencesafe and effective for a particular patient population. After a product has been approved or authorized and launched, we continue to monitor its safety as long as it is available to patients, including conducting postmarketing trials, voluntarily or pursuant to a regulatory request. For the entire life of the product, we collect safety data and report safety information to the FDA and other regulators. Regulatory authorities evaluate potential safety concerns and take any regulatory action deemed necessary and appropriate. Such action(s) may include: updating a product’s labeling, restricting its use, communicating new safety information or, in rare cases, seeking to suspend or remove a product from the market.
Intellectual Property Rights and Collaboration/Licensing Rights––The loss, expiration or invalidation of intellectual property rights, patent litigation settlements and judgments, and the expiration of co-promotion and licensing rights can have a material adverse effect on our revenues. Certain of our products have experienced patent-based expirations or loss of regulatory exclusivity in certain markets in the last few years, and we expect certain products to face increased generic competition over the next few years. While additional patent expiries will continue, we expect a moderate impact of reduced revenues due to patent expiries from 2024 through 2025. We anticipate a more significant impact of reduced revenues from patent expiries in 2026 through 2030 as several of our in-line products experience patent-based expirations. We continue to vigorously defend our patent rights against infringement, and we will continue to support efforts that strengthen worldwide recognition of patent rights while taking necessary steps to help ensure appropriate patient access.
For additional information on patent rights we consider most significant to our business as a whole, see the Item 1. Business––Patents and Other Intellectual Property Rights section. For a discussion of recent developments with respect to patent litigation, see Note 16A1.
Regulatory Environment/Pricing and Access––Government and Other Payor Group Pressures––The pricing of medicines and vaccines by pharmaceutical manufacturers and the cost of healthcare, which includes medicines, vaccines, medical services and hospital services, continues to be important to payors, governments, patients, and other stakeholders. Federal and state governments and private third-party payors in the U.S. continue to take action to manage the utilization and cost of drugs, including increasingly employing formularies to control costs and encourage utilization of certain drugs, including through the use of deductibles, utilization management tools, cost sharing or formulary placement. We consider a number of factors impacting the pricing of our medicines and vaccines. Within the U.S., we often engage with patients, doctors and healthcare plans. We also often provide significant discounts from the list price to insurers, including PBMs and MCOs. The price that patients pay in the U.S. for prescribed medicines and vaccines is ultimately set by healthcare providers and insurers. Governments globally, as well as private third-party payors in the U.S., may use a variety of measures to control costs, including, among others, legislative or regulatory pricing reforms, drug formularies (including tiering and utilization management tools), cross country collaboration and procurement, price cuts, mandatory rebates, health technology assessments, forced localization as a condition of market access, “international reference pricing” (i.e., the practice of a country linking its regulated medicine prices to those of other countries), QCE processes and VBP. We anticipate that these and similar initiatives will continue to increase pricing and access pressures globally. In the U.S., we expect to see continued focus by Congress and the Biden Administration on regulating pricing. The drug pricing provisions of the IRA, which was signed into law in August 2022, began to be implemented in 2022 and implementation efforts will continue over the next several years. In August 2023, the Biden Administration unveiled the first ten medicines subject to the “Medicare Drug Price Negotiation Program,” which requires manufacturers of select drugs to engage in a process with the federal government to set new Medicare prices which would go into effect in 2026. Among the first ten medicines subject to the Program included Eliquis. We continue to evaluate the impact of the IRA on our business, operations and financial condition and results as the full effect of the IRA on our business and the pharmaceutical industry remains uncertain. In addition, changes to the Medicaid Drug Rebate program or the 340B Program, including legal or legislative developments at the federal or state level with respect to the 340B program, could have a material impact on our business. See the Item 1. Business––Pricing Pressures and Managed Care Organizationsand ––Government Regulation and Price Constraints and the Item 1A. Risk Factors––Pricing and Reimbursementsections.
Impact of the July 2023 Tornado in Rocky Mount, North Carolina (NC)––Our manufacturing facility in Rocky Mount, NC was damaged by a tornado in July 2023. The facility is a key producer of sterile injectables and is responsible for manufacturing nearly 25 percent of all our sterile injectables—including anesthesia, analgesia, and micronutrients—which is nearly eight percent of all the sterile injectables used in U.S. hospitals. While manufacturing has resumed, the supply of medicines impacted by the tornado is expected to be affected through 2024.
In 2023, we recorded $286 million to Cost of sales for inventory losses, overhead costs related to the period in which the facility could not operate, and incremental costs resulting from the tornado damage. Losses incurred in 2023 were partially offset by insurance recoveries received in the fourth quarter of 2023. We may record additional losses and/or costs and/or insurance recoveries in future periods, but we are unable to predict them with certainty at this time.

Pfizer Inc.2023 Form 10-K32


Product Supply––We periodically encounter supply delays, disruptions and shortages, including due to voluntary product recalls and natural or man-made disasters. In 2021, Pfizer recalled all lots of Chantix in the U.S. due to the presence of a nitrosamine, N-nitroso-varenicline, at or above the FDA interim acceptable intake limit. Regulatory authorities outside the U.S. have issued updated guidance on nitrosamine acceptable intake levels. With this recently issued guidance, which included an updated intake level for N-nitroso-varenicline, we expect to make regulatory submissions in 2024 to potentially enable Chantix to return to market outside the U.S., and our related discussions with FDA are ongoing.
Except for the tornado in Rocky Mount, NC discussed above, we have not seen a significant disruption of our supply chain in 2023 and through the date of filing of this Form 10-K, and all of our manufacturing sites globally have continued to operate at or near normal levels; however, we continue to see heightened demand in the industry for certain components and raw materials, which could potentially result in constraining available supply leading to a possible future impact on our business. We continue to monitor and implement mitigation strategies in an effort to reduce any potential risk or impact including active supplier management, qualification of additional suppliers and advanced purchasing to the extent possible. For information on risks related to product manufacturing, see the Item 1A. Risk Factors––Product Manufacturing, Sales and Marketing Risks section.
The Global Economic Environment––In addition to the industry-specific factors discussed above, we, like other businesses of our size and global extent of activities, are exposed to economic cycles. Certain factors in the global economic environment that may impact our global operations include, among other things, currency and interest rate fluctuations, capital and exchange controls, local and global economic conditions including inflation, recession, volatility and/or lack of liquidity in capital markets, expropriation and other restrictive government actions, changes in intellectual property, legal protections and remedies, trade regulations, tax laws and regulations and procedures and actions affecting approval, production, pricing, and marketing of, reimbursement for and access to our products, as well as impacts of political or civil unrest or military action, including the ongoing conflicts between Russia and Ukraine and in the Middle East and their economic consequences, geopolitical instability, terrorist activity, unstable governments and legal systems, inter-governmental disputes, public health outbreaks, epidemics, pandemics, natural disasters or disruptions related to climate change. Government pressures can lead to negative pricing pressure in various markets where governments take an active role in setting prices, access criteria or other means of cost control. For additional information on risks related to our global operations, see theItem 1A. Risk Factors—Global Operationssection.
COVID-19––In response to COVID-19, we developed Paxlovid and collaborated with BioNTech to jointly develop Comirnaty, including an Omicron XBB.1.5-adapted monovalent vaccine. As part of our strategy for COVID-19, we are continuing to make significant investments in breakthrough science and global manufacturing. This includes continuing to evaluate Comirnaty and Paxlovid, including against new variants of concern, developing variant adapted vaccine candidates and developing potential combination respiratory vaccines and potential next generation vaccines and therapies. We are also evaluating Paxlovid for additional populations. See the Product Developments section within MD&A.
In 2023, we principally sold Comirnaty globally under government contracts. In September 2023, Comirnaty transitioned to traditional commercial market sales in the U.S., triggered by the expiration of current contracts and the COVID-19 vaccines from Pfizer and BioNTech purchased through them becoming either depleted or not used following the introduction of a new variant vaccine. Internationally, sales of Comirnaty in international developed markets were generally under government contracts in 2023, and in emerging markets, under a combination of private channels and government contracts; in both cases, we expect to start transitioning to commercial markets in 2024. Due to the commercial market transition as well as the anticipated seasonal nature of COVID vaccination, we expect more than 80% of our 2024 global revenues for Comirnaty to be recorded in the second half of the year.
In 2023, we principally sold Paxlovid globally to government agencies. Internationally, for Paxlovid, we are continuing the transition to commercial markets and are expecting most revenue for Paxlovid to be generated through commercial channels in 2024. On October 13, 2023, we announced an amended agreement with the U.S. government, which facilitated the transition of Paxlovid to traditional commercial markets in November 2023, with minimal uptake of NDA-labeled commercial product before January 1, 2024. See Note 17C.
For information on risks associated with our COVID-19 products, including certain assumptions made for purposes of our operational planning and financial projections and the uncertainty of future developments, as well as COVID-19 intellectual property disputes, see theItem 1A. Risk FactorsCOVID-19, Intellectual Property Protectionand ––Third-Party Intellectual Property Claims sections and Note 16A1.
Israel/Hamas Conflict––Our local operations have been impacted by the armed conflict between Israel and Hamas that began on October 7, 2023. For the years ended December 31, 2023 and 2022, the business of our Israeli subsidiary represented less than 1% of our consolidated revenues and assets. We are closely monitoring developments in this conflict, including evaluating potential impacts to our business, customers, suppliers, employees, and operations in Israel and elsewhere in the Middle East that may impact global operations. At this time, longer term impacts to the Company are uncertain and subject to change.
Russia/Ukraine Conflict––Our local operations have been impacted by the armed conflict between Russia and Ukraine. For the years ended December 31, 2023 and 2022, the business of our Russia and Ukraine subsidiaries represented less than 1% of our consolidated revenues and assets, and while we are monitoring the effects of the conflict between Russia and Ukraine, the situation continues to evolve and the long-term implications, including the broader economic consequences of the conflict, are difficult to predict at this time. While as of now, we do not anticipate any significant negative impacts on our global operations from this conflict, continued regional instability, geopolitical shifts, potential additional sanctions and other restrictive measures against Russia, neighboring countries or allies of Russia, any retaliatory measures taken by Russia, neighboring countries or allies of Russia, and actions by our customers or suppliers, including financial institutions, in response to such measures could adversely affect the global macroeconomic environment, our operations, currency exchange rates and financial markets, which could in turn adversely impact our business and results of operations.
SIGNIFICANT ACCOUNTING POLICIES AND APPLICATION OF CRITICAL ACCOUNTING ESTIMATES AND ASSUMPTIONS
Following is a discussion about the critical accounting estimates and assumptions impacting our consolidated financial statements. Also, see Note 1C.
For a description of our significant accounting policies, see Note 1. Of these policies, the following are considered critical to an understanding of our consolidated financial statements as they require the application of the most subjective and the most complex judgments: Acquisitions (Note 1D); Fair Value (Note 1E); Revenues (Note 1G); Asset Impairments (Note 1M); Tax Assets and Liabilities andIncome Tax Contingencies (Note 1Q); Pension and Postretirement Benefit Plans (Note 1R); and Legal and Environmental Contingencies (Note 1S).
For a discussion of recently adopted accounting standards, see Note 1B.

Pfizer Inc.2023 Form 10-K33


Acquisitions
We account for acquired businesses using the acquisition method of accounting, which requires, among other things, that most assets acquired and liabilities assumed be recognized at their estimated fair value as of the acquisition date. To estimate fair value, we utilize an exit price approach from the perspective of a market participant. For further detail on acquisition accounting, see Note 1D. For further detail on the techniques and methodologies that we use to estimate fair value, see Note 1E. Historically, intangible assets have been the most significant fair values within our business combinations. We utilize an income approach to estimate the acquisition date fair value of each identifiable intangible asset. Some of the more significant estimates and assumptions inherent in this approach include the amount and timing of projected net cash flows, the discount rate, the tax rate, and, for IPR&D assets, the probability of technical and regulatory success (PTRS). All of these judgments and estimates can materially impact our results of operations. For further information on our process to estimate the fair value of intangible assets, see Asset Impairments below.
We estimate the fair value of acquired inventory, including finished goods and work in process, by determining the estimated selling price when completed, less an estimate of costs to be incurred to complete and sell the inventory, and an estimate of a reasonable profit allowance for those manufacturing and selling efforts. The fair value of inventory is recognized in our results of operations as the inventory is sold. Some of the more significant estimates and assumptions inherent in the estimate of the fair value of inventory include stage of completion, costs to complete, costs to dispose and selling price.
We estimate the fair value of acquired PP&E using a combination of the cost and market approaches. Some of the more significant estimates and assumptions inherent in these approaches are the values of asset replacement costs, comparable assets and estimated remaining economic lives of the assets.
For the provisional amounts recognized for the Seagen assets acquired and liabilities assumed as of the acquisition date, see Note 2A. The estimated values are not yet finalized and are subject to change, which could be significant. We will finalize the amounts recognized as we obtain the information necessary to complete the analyses. We expect to finalize the amounts of assets acquired and liabilities assumed as soon as possible but no later than one year from the acquisition date.
Revenues
Our gross product revenues are subject to a variety of deductions, which generally are estimated and recorded in the same period that the revenues are recognized. Such variable consideration represents chargebacks, rebates, sales allowances and sales returns. These deductions represent estimates of the related obligations and, as such, knowledge and judgment are required when estimating the impact of these revenue deductions on gross sales for a reporting period. Historically, adjustments to these estimates to reflect actual results or updated expectations, have not been material to our overall business and generally have been less than 1% of revenues. Product-specific rebates, however, can have a significant impact on year-over-year individual product revenue growth trends. If any of our ratios, factors, assessments, experiences or judgments are not indicative or accurate estimates of our future experience, our results could be materially affected. The potential of our estimates to vary (sensitivity) differs by program, product, type of customer and geographic location. However, estimates associated with U.S. Medicare, Medicaid and performance-based contract rebates are most at risk for material adjustment because of the extensive time delay between the recording of the accrual and its ultimate settlement, an interval that can generally range up to one year. Because of this lag, our recording of adjustments to reflect actual amounts can incorporate revisions of several prior quarters. Rebate accruals are product specific and, therefore for any period, are impacted by the mix of products sold as well as the forecasted channel mix for each individual product. For further information, see the Product Revenue Deductions section within MD&A and Note 1G.
Asset Impairments
We review all of our long-lived assets for impairment indicators throughout the year. We perform impairment testing for indefinite-lived intangible assets and goodwill at least annually and for all other long-lived assets whenever impairment indicators are present. When necessary, we record charges for impairments of long-lived assets for the amount by which the fair value is less than the carrying value of these assets. Our impairment review processes are described in Note 1M.
Examples of events or circumstances that may be indicative of impairment include:
A significant adverse change in legal factors or in the business climate that could affect the value of the asset. For example, a successful challenge of our patent rights would likely result in generic competition earlier than expected.
A significant adverse change in the extent or manner in which an asset is used such as a restriction imposed by the FDA or other regulatory authorities that could affect our ability to manufacture or sell a product.
An expectation of losses or reduced profits associated with an asset. This could result, for example, from a change in a government reimbursement program that results in an inability to sustain projected product revenues and profitability. This also could result from the introduction of a competitor’s product that impacts projected revenue growth, as well as the lack of acceptance of a product by patients, physicians and payors. For IPR&D projects, this could result from, among other things, a change in outlook based on clinical trial data, a delay in the projected launch date or additional expenditures to commercialize the product.
Identifiable Intangible Assets––We use an income approach, specifically the discounted cash flow method to determine the fair value of intangible assets, other than goodwill. We start with a forecast of all the expected net cash flows associated with the asset, which incorporates the consideration of a terminal value for indefinite-lived assets, and then we apply an asset-specific discount rate to arrive at a net present value amount. Some of the more significant estimates and assumptions that impact our fair value estimates include: the amount and timing of the projected net cash flows, which includes the expected impact of competitive, legal and/or regulatory forces on the projections and the impact of technological advancements and risk associated with IPR&D assets, as well as the selection of a long-term growth rate; the discount rate, which seeks to reflect the various risks inherent in the projected cash flows; and the tax rate, which seeks to incorporate the jurisdictional mix of the projected cash flows.
While all intangible assets other than goodwill can face events and circumstances that can lead to impairment, those that are most at risk of impairment include IPR&D assets (approximately $23.2 billion as of December 31, 2023) and newly acquired or recently impaired indefinite-lived brand assets. IPR&D assets are high-risk assets, given the uncertain nature of R&D. Newly acquired and recently impaired indefinite-lived assets are more vulnerable to impairment as the assets are recorded at fair value and are then subsequently measured at the lower of fair value or carrying value at the end of each reporting period. As such, immediately after acquisition or impairment, even small declines in the outlook for these assets can negatively impact our ability to recover the carrying value and can result in an impairment charge.

Pfizer Inc.2023 Form 10-K34


Goodwill––Our goodwill impairment review work as of December 31, 2023 concluded that none of our goodwill was impaired and we do not believe the risk of impairment is significant at this time, as the fair value of each of our reporting units is significantly higher than their respective net book values.
In our review, we first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. Qualitative factors that we consider include, for example, macroeconomic and industry conditions, overall financial performance and other relevant entity-specific events. If we conclude that it is more likely than not that the fair value of a reporting unit is less than its carrying value, we then perform a quantitative fair value test.
When we are required to determine the fair value of a reporting unit, we typically use the income approach. The income approach is a forward-looking approach to estimating fair value and relies primarily on internal forecasts. Within the income approach, we use the discounted cash flow method. We start with a forecast of all the expected net cash flows for the reporting unit, which includes the application of a terminal value, and then we apply a reporting unit-specific discount rate to arrive at a net present value amount. Some of the more significant estimates and assumptions inherent in this approach include: the amount and timing of the projected net cash flows, which includes the expected impact of technological risk and competitive, legal and/or regulatory forces on the projections, as well as the selection of a long-term growth rate; the discount rate, which seeks to reflect the various risks inherent in the projected cash flows; and the tax rate, which seeks to incorporate the geographic diversity of the projected cash flows.
For all of our reporting units, there are a number of future events and factors that may impact future results and that could potentially have an impact on the outcome of subsequent goodwill impairment testing. For a list of these factors, see the Forward-Looking Information and Factors That May Affect Future Results—FinancialResults and the Item 1A. Risk Management sectionFactors sections.
Benefit Plans
For a description of our different benefit plans, seeNote 11.
Our assumptions reflect our historical experiences and our judgment regarding future expectations that have been deemed reasonable by management. The judgments made in determining the costs of our benefit plans can materially impact our results of operations.
The following provides (i) at the end of each year, the expected annual rate of return on plan assets for the following year, (ii) the actual annual rate of return on plan assets achieved in each year, and (iii) the weighted-average discount rate used to measure the benefit obligations at the end of each year for our U.S. pension plans and our international pension plans(a):

(a)For detailed assumptions associated with our benefit plans, see Note 11B.
Expected Annual Rate of Return on Plan Assets––The assumptions for the expected annual rate of return on all of our plan assets reflect our actual historical return experience and our long-term assessment of forward-looking return expectations by asset classes, which is used to develop a weighted-average expected return based on the implementation of our targeted asset allocation in our 2017 Financial Report.respective plans.

The expected annual rate of return on plan assets for our U.S. plans and international plans is applied to the fair value of plan assets at each year-end and the resulting amount is reflected in our net periodic benefit costs in the following year. Differences between the actual rate of return on plan assets and the expected annual rate of return on plan assets are immediately recognized through earnings upon remeasurement.
The following illustrates the sensitivity of net periodic benefit costs to a 50 basis point decline in our assumption for the expected annual rate of return on plan assets, holding all other assumptions constant (in millions, pre-tax):
AssumptionChange

(a)The estimate excludes any potential mark-to-market adjustments.

The actual return on plan assets resulted in a net gain on our plan assets of approximately $835 million during 2023.
Discount Rate Used to Measure Plan Obligations––The weighted-average discount rate used to measure the plan obligations for our U.S. defined benefit plans is determined at least annually and evaluated and modified, as required, to reflect the prevailing market rate of a portfolio of high-quality fixed income investments, rated AA/Aa or better, that reflect the rates at which the pension benefits could be effectively settled. The discount rate used to measure the plan obligations for our significant international plans is determined at least annually by reference to investment grade corporate bonds, rated AA/Aa or better, including, when there is sufficient data, a yield-curve approach. These discount rate determinations are made in consideration of local requirements. The measurement of plan obligations at the end of the year will affect (i) the actuarial (gains)/losses recognized in our net periodic benefit cost for that year and (ii) the amount of service cost and interest cost reflected in our net periodic benefit costs in the following year.

The following illustrates the sensitivity of net periodic benefit costs and benefit obligations to a 10 basis point decline in our assumption for the discount rate, holding all other assumptions constant (in millions, pre-tax):
AssumptionChangeDecrease in 2024 Net Periodic Benefit CostsIncrease to 2023 Benefit Obligations

The change in the discount rates used in measuring our plan obligations as of December 31, 2023 resulted in a decrease in the measurement of our aggregate plan obligations by approximately $616 million.
Income Tax Assets and Liabilities
Income tax assets and liabilities include income tax valuation allowances and accruals for uncertain tax positions. See Notes 1Qand 5, as well as the Analysis of Financial Condition, Liquidity, Capital Resources and Market Risk section within MD&A.
Contingencies

We and certain of our subsidiaries are subject to numerous contingencies arising in the ordinary course of business, including tax and legal contingencies, guarantees and indemnifications. See Notes 1Q,1S,5D and 16.

The operational decrease in emerging markets revenues was primarily driven by declines from Comirnaty and Paxlovid, partially offset by growth from Lorbrena, Zavicefta and Eliquis.
See the Total Revenues––Selected Product Discussion section within MD&A for additional analysis.
Product Revenue Deductions––Our gross product revenues are subject to a variety of deductions, which generally are estimated and recorded in the same period that the revenues are recognized. These deductions represent estimates of the related obligations and, as such, knowledge and judgment are required when estimating the impact of these product revenue deductions on gross sales for a reporting period. Historically, adjustments to these estimates to reflect actual results or updated expectations, have not been material to our overall business and generally have been less than 1% of revenues. Product-specific rebates, however, can have a significant impact on year-over-year individual product revenue growth trends.

2023 v. 2022
Cost of Sales
Cost of sales decreased $9.4 billion, primarily due to:
a reduction of $14.2 billion due to lower sales of Comirnaty; and
a reduction of $1.5 billion due to lower sales of Paxlovid,
partially offset by:
non-cash charges of $6.2 billion for inventory write-offs and related charges ($5.0 billion for Paxlovid and $1.2 billion for Comirnaty).
The increase in Cost of sales as a percentage of Total revenues was mainly driven by the non-cash charge of $6.2 billion discussed above, and unfavorable changes in sales mix, primarily due to lower sales of Paxlovid and Comirnaty, which includes the unfavorable impact of the $3.5 billion non-cash Paxlovid revenue reversal.
Selling, Informational and Administrative Expenses
Selling, informational and administrative expenses increased $1.1 billion, mostly due to:
an increase of $1.1 billion in marketing and promotional expenses for recently acquired and launched products;
an increase of $280 million for the expected Paxlovid commercial launch;
an increase of $210 million in our liability to be paid to participants of our supplemental savings plan; and
an increase of $170 million in marketing and promotional expenses for rare disease products,
partially offset by:
a decrease of $690 million due to a lower provision for U.S. healthcare reform fees related to Comirnaty and Paxlovid.
Research and Development Expenses
Research and development expenses decreased $749 million, primarily due to:
lower spending of $870 million mainly for lower compensation-related expenses, and ongoing vaccine and hospital programs, as well as
a decrease of $260 million in the value of the portfolio performance share grants reflecting the decrease in the price of Pfizer’s common stock,

Pfizer Inc.2023 Form 10-K39


partially offset by:
increased investments of $345 million, mainly to develop certain acquired assets, as well as activities to support upcoming product launches.
Acquired In-Process Research and Development Expenses
Acquired in-process research and development expenses decreased $758 million primarily reflecting the non-recurrence of:
an upfront payment of $426 million related to the closing of the acquisition of ReViral Ltd. in 2022;
an upfront payment to Biohaven and a premium paid on our equity investment in Biohaven totaling $263 million in 2022; and
a $76 million premium paid on our equity investment in BioNTech to develop a potential mRNA vaccine against shingles, both recorded in 2022.
See Notes 2Aand 2E.
Amortization of Intangible Assets
Amortization of intangible assets increased $1.1 billion, primarily as a result of 2023 reflecting a full year of amortization of intangible assets from our acquisitions of Biohaven and GBT, higher amortization of intangible assets related to Prevnar, as well as reclassifications of IPR&D to developed technology rights, partially offset by fully amortized assets. See Notes 2Aand 10A.
Restructuring Charges and Other Costs Associated with Acquisitions and Cost-Reduction/Productivity Initiatives
Transforming to a More Focused Company Program––In connection with restructuring our corporate enabling functions, we achieved gross cost savings of $1.0 billion, or net cost savings, excluding merit and inflation growth and certain real estate cost increases, of $700 million, in the two year period from 2021 through 2022. In connection with transforming our commercial go-to market strategy, we expect net cost savings of $1.4 billion, to be achieved primarily from 2022 through 2024. In connection with manufacturing network optimization, we achieved net cost savings of $550 million. In connection with optimizing our end-to-end R&D operations, we expect net cost savings of $2.3 billion to be achieved primarily from 2023 through 2025.
Realigning our Cost Base Program––This program is expected to deliver net cost savings of at least $4 billion, to be achieved primarily from 2023 through 2024.
Certain qualifying costs for these programs were recorded in 2023, 2022 and 2021, and are reflected as Certain Significant Items and excluded from our non-GAAP measure of Adjusted Income. See the Non-GAAP Financial Measure: Adjusted Income section within MD&A.
In connection with our acquisition of Seagen, we are focusing our efforts on achieving an appropriate cost structure for the combined company. We expect to generate approximately $1 billion of annual cost synergies, to be achieved by 2026.
For a description of our programs, as well as the anticipated and actual costs, see Note 3A, The program savings discussed above may be rounded and represent approximations. In addition to these programs, we continuously monitor our operations for cost reduction and/or productivity opportunities, especially in light of the losses of exclusivity and the expiration of collaborative arrangements for various products.
Other (Income)/Deductions––Net
The favorable period-over-period change of $1.1 billion was primarily driven by net gains on equity securities in 2023 versus net losses recognized on equity securities in 2022 and lower net interest expense, partially offset by higher intangible asset impairment charges. See
Note 4.
Upjohn Separation Costs
Since inception through December 31, 2023, we have incurred substantially all costs of approximately $700 million in connection with separating Upjohn, including costs and expenses related to separation of legal entities and transaction costs.

For information about our effective tax rate and the events and circumstances contributing to the changes between periods, as well as details about discrete elements that impacted our tax provisions, see Note 5.

Changes in Tax Laws––Many countries outside the U.S. have enacted legislation for global minimum taxation resulting from the Organization for Economic Co-operation and Development’s (OECD) Base Erosion and Profit Shifting “Pillar 2” project. The EU has approved a directive requiring member states to incorporate the OECD provisions into their respective domestic laws, and other countries outside the EU are also enacting the provisions into their domestic law. The provisions are generally effective for Pfizer in 2024, though significant details and guidance around the provisions are still pending. Income tax expense could be adversely affected as the legislation becomes effective in countries in which we do business, and such impact could be material to our results of operations. We continue to monitor pending OECD guidance and legislation enactment and implementation by individual countries.

PRODUCT DEVELOPMENTS
A comprehensive update of Pfizer’s development pipeline was published as of January 30, 2024 and is available at www.pfizer.com/science/drug-product-pipeline. It includes an overview of our research and a list of compounds in development with targeted indication and phase of development, as well as mechanism of action for some candidates in Phase 1 and all candidates from Phase 2 through registration.
This section provides information as of the date of this filing about significant marketing application-related regulatory actions by, and filings pending with, the FDA and regulatory authorities in the EU and Japan.
The tables below include filing and approval milestones for products that have occurred in the last twelve months and generally do not include approvals that may have occurred prior to that time. The tables include filings with regulatory decisions pending (even if the filing occurred outside of the last twelve-month period).
COVID-19 Vaccine Products
Beginning with the original monovalent Pfizer-BioNTech COVID-19 Vaccine, initially authorized for emergency use, to Comirnaty (COVID-19 Vaccine, mRNA, 2023-2024 Formula), approved by the FDA for individuals 12 years and older and the Pfizer-BioNTech COVID-19 Vaccine (2023-2024 Formula) authorized by the FDA for emergency use for individuals 6 months through 11 years of age, efforts to stay current with circulating COVID-19 strains have resulted in the rapid development of targeted, adapted vaccines for licensure in the U.S., Europe, Japan and other markets. The adapted vaccines have included two bivalent formulations (Original and Omicron BA.1, not authorized in the U.S., and Original and Omicron BA.4/BA.5). As updated COVID-19 vaccines are formulated to more closely target currently circulating vaccines, prior vaccine formulations are generally no longer utilized in a majority of the markets.
The 2023-2024 Formula includes a monovalent (single) component that corresponds to the Omicron sub-variant XBB.1.5 of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The table below summarizes the approval of the 2023-2024 Formula in the markets indicated:

NON-GAAP FINANCIAL MEASURE: ADJUSTED INCOME
Adjusted income is an alternative measure of performance used by management to evaluate our overall performance as a supplement to our GAAP Reported performance measures. As such, we believe that investors’ understanding of our performance is enhanced by disclosing this measure. We use Adjusted income, certain components of Adjusted income and Adjusted diluted EPS to present the results of our major operations––the discovery, development, manufacture, marketing, sale and distribution of biopharmaceutical products worldwide––prior to considering certain income statement elements as follows:
MeasureDefinitionRelevance of Metrics to Our Business Performance
Adjusted income
Net income attributable to Pfizer Inc. common shareholders(a)
before the impact of amortization of intangible assets, certain acquisition-related items, discontinued operations and certain significant items
Provides investors useful information to:
evaluate the normal recurring operational activities, and their components, on a comparable year-over-year basis
assist in modeling expected future performance on a normalized basis
Provides investors insight into the way we manage our budgeting and forecasting, how we evaluate and manage our recurring operations and how we reward and compensate our senior management(b)
Adjusted cost of sales, Adjusted selling, informational and administrative expenses, Adjusted research and development expenses and Adjusted other (income)/deductions––net
Cost of sales, Selling, informational and administrative expenses, Research and development expenses and Other (income)/deductions––net (a), each before the impact of amortization of intangible assets, certain acquisition-related items, discontinued operations and certain significant items, which are components of the Adjusted income measure
Adjusted diluted EPS
EPS attributable to Pfizer Inc. common shareholders––diluted (a) before the impact of amortization of intangible assets, certain acquisition-related items, discontinued operations and certain significant items
(a)Most directly comparable GAAP measure.
(b)The short-term incentive plans for substantially all non-sales-force employees worldwide are funded from a pool based on our performance, measured in significant part versus three budgeted metrics, one of which is Adjusted diluted EPS (as defined for annual incentive compensation purposes), which is derived from Adjusted income and accounts for 40% of the bonus pool funding tied to financial performance. Additionally, the payout for performance share awards is determined in part by Adjusted net income, which is derived from Adjusted income. Beginning in the first quarter of 2022, we no longer exclude any expenses for acquired IPR&D from our non-GAAP Adjusted results but we continue to exclude certain of these expenses for our financial results for annual incentive compensation purposes. The bonus pool funding, which is largely based on financial performance, is adjusted by our R&D pipeline performance, as measured by four metrics, and performance against certain of our ESG metrics, and may be further modified by our Compensation Committee’s assessment of other factors.
Adjusted income and its components and Adjusted diluted EPS are non-GAAP financial measures that have no standardized meaning prescribed by GAAP and, therefore, are limited in their usefulness to investors. Because of their non-standardized definitions, they may not be comparable to the calculation of similar measures of other companies and are presented to permit investors to more fully understand how management assesses performance. A limitation of these measures is that they provide a view of our operations without including all events during a period, and do not provide a comparable view of our performance to peers. These measures are not, and should not be viewed as, substitutes for their most directly comparable GAAP measures of Net income attributable to Pfizer Inc. common shareholders, components of Net income attributable to Pfizer Inc. common shareholders and EPS attributable to Pfizer Inc. common shareholders—diluted, respectively.
We also recognize that, as internal measures of performance, these measures have limitations, and we do not restrict our performance-management process solely to these measures. We also use other tools designed to achieve the highest levels of performance. For example, our R&D organization has productivity targets, upon which its effectiveness is measured. In addition, total shareholder return, both on an absolute basis and relative to a publicly traded pharmaceutical index, plays a significant role in determining payouts under certain of our incentive compensation plans.
Adjusted Income and Adjusted Diluted EPS
Amortization of Intangible Assets—Adjusted income excludes all amortization of intangible assets.
Acquisition-Related Items––Adjusted income excludes certain acquisition-related items, which are composed of transaction, integration, restructuring charges and additional depreciation costs for business combinations because these costs are unique to each transaction and represent costs that were incurred to restructure and integrate businesses as a result of an acquisition. We have made no adjustments for resulting synergies.
The significant costs incurred in connection with a business combination result primarily from the need to eliminate duplicate assets, activities or employees––a natural result of acquiring a fully integrated set of activities. For this reason, we believe that such costs incurred can be viewed differently in the context of an acquisition from those costs incurred in other, more normal, business contexts. The integration and restructuring costs for a business combination may occur over several years, with the more significant impacts typically ending within three years of the relevant transaction. Because of the need for certain external approvals for some actions, the span of time needed to achieve certain restructuring and integration activities can be lengthy.
Acquisition-related items may include purchase accounting impacts such as the incremental charge to cost of sales from the sale of acquired inventory that was written up to fair value, depreciation related to the increase/decrease in fair value of acquired fixed assets, amortization related to the increase in fair value of acquired debt, and the fair value changes for contingent consideration.

Pfizer Inc.2023 Form 10-K44


Discontinued Operations––Adjusted income excludes the results of discontinued operations, as well as any related gains or losses on the disposal of such operations. We believe that this presentation is meaningful to investors because, while we review our product portfolio for strategic fit with our operations, we do not build or run our business with the intent to discontinue parts of our business. Restatements due to discontinued operations do not impact compensation or change the Adjusted income measure for the compensation in respect of the restated periods, but are presented for consistency across all periods.
Certain Significant Items––Adjusted income excludes certain significant items representing substantive and/or unusual items that are evaluated individually on a quantitative and qualitative basis. Certain significant items may be highly variable and difficult to predict. Furthermore, in some cases it is reasonably possible that they could reoccur in future periods. For example, although major non-acquisition-related cost-reduction programs are specific to an event or goal with a defined term, we may have subsequent programs based on reorganizations of the business, cost productivity or in response to LOE or economic conditions. Legal charges to resolve litigation are also related to specific cases, which are facts and circumstances specific and, in some cases, may also be the result of litigation matters at acquired companies that were inestimable, not probable or unresolved at the date of acquisition, or legal matters related to divested products or businesses. Gains and losses on equity securities and pension and postretirement actuarial remeasurement gains and losses have a very high degree of inherent market volatility, which we do not control and cannot predict with any level of certainty, and we do not believe including these gains and losses assists investors in understanding our business or is reflective of our core operations and business. Unusual items represent items that are not part of our ongoing business; items that, either as a result of their nature or size, we would not expect to occur as part of our normal business on a regular basis; items that would be non-recurring; or items that relate to products we no longer sell. See the Reconciliations of GAAP Reported to Non-GAAP Adjusted Information––Certain Line Items below for a non-inclusive list of certain significant items.

ANALYSIS OF THE CONSOLIDATED STATEMENTS OF CASH FLOWS
For a discussion of the drivers of change for 2022 versus 2021 as well as cash flows from discontinued operations in 2021, see the Analysis of the Consolidated Statements of Cash Flows sectionwithin MD&A in our 2022 Form 10-K.
Cash Flows from Continuing Operations
 Year Ended December 31,
(MILLIONS)202320222021Drivers of change 2023 v. 2022
Cash provided by/(used in):
Operating activities from continuing operations$8,700 $29,267 $32,922 
The change was driven primarily by a decrease in net income adjusted for non-cash items and the timing of receipts and payments in the ordinary course of business, partially offset by net changes in inventory greater than one year (see Note 8A).
Investing activities from continuing operations$(32,278)$(15,783)$(22,534)
The change was driven mainly by $43.4 billion cash paid in 2023 for the acquisition of Seagen, net of cash acquired, compared with $23.0 billion cash paid in 2022 for acquisitions (Biohaven, $11.5 billion, Arena, $6.2 billion and GBT, $5.2 billion), net of cash acquired (see Note 2A), as well as a $4.0 billion dividend received from the Consumer Healthcare JV in 2022 that was allocated to investing activities (see Note 2C), partially offset by a $5.5 billion increase in net redemptions of short-term investments in 2023 and a $1.7 billion decrease in purchases of long-term investments.
Financing activities from continuing operations$26,066 $(14,834)$(9,816)The change was driven mostly by $30.8 billion of proceeds from the issuance of long-term debt in May of 2023 and a $7.9 billion increase in net proceeds from the issuance of short-term borrowings.
ANALYSIS OF FINANCIAL CONDITION, LIQUIDITY, CAPITAL RESOURCES AND MARKET RISK
Our historically robust operating cash flow, which we expect to continue over time, is a key strength of our liquidity and capital resources and our primary funding source. We believe as a result of this, together with our financial assets, access to capital markets, revolving credit agreements, and available lines of credit, we have and will maintain the ability to meet our liquidity needs to support ongoing operations, our capital allocation objectives, and our contractual and other obligations for the foreseeable future.
We focus efforts to optimize operating cash flows through achieving working capital efficiencies that target accounts receivable, inventories, accounts payable, and other working capital. Excess cash from operating cash flows is invested in money market funds and available-for-sale debt securities which consist of primarily high-quality, highly liquid, well-diversified debt securities. We have taken, and will continue to take, a conservative approach to our financial investments and monitoring of our liquidity position in response to market changes. We typically maintain cash and cash equivalent balances and short-term investments which, together with our available revolving credit facilities, are in excess of our commercial paper and other short-term borrowings.
Additionally, we may obtain funding through short-term or long-term sources from our access to the capital markets, banking relationships and relationships with other financial intermediaries to meet our liquidity needs.

Financing for Seagen Acquisition––As part of the financing for our acquisition of Seagen, we issued $31 billion of long-term debt in May 2023 and $8 billion of commercial paper in the fourth quarter of 2023. The net proceeds from long-term debt were invested in short-term investments in a combination of money market funds and available-for-sale debt securities until the completion of the acquisition.

Pfizer Inc.2023 Form 10-K47


Credit Ratings––The cost and availability of financing are influenced by credit ratings, and an increase or decrease in our credit rating could have a beneficial or adverse effect on financing. Our long-term debt is rated high-quality by both S&P and Moody’s. In March 2023, following the announcement of the proposed acquisition of Seagen, Moody’s changed its outlook on our long-term debt to Negative; S&P downgraded our short-term rating from A-1+ to A-1. In October 2023, following the announcement of the amended Paxlovid supply agreement with the U.S. government and updated 2023 guidance, S&P changed its outlook on our long-term debt to Negative. In December 2023, following the release of 2024 guidance (i) Moody’s downgraded our long-term rating from A1 to A2 and changed its outlook on our long-term debt to Stable and (ii) S&P downgraded our long-term rating from A+ to A and changed its outlook on our long-term debt to Stable.
As of the date of the filing of this Form 10-K, the following ratings have been assigned to our commercial paper and senior unsecured long-term debt:
NAME OF RATING AGENCYPfizer Short-Term RatingPfizer Long-Term RatingOutlook/Watch
Moody’sP-1A2Stable Outlook
S&PA-1AStable Outlook
These ratings are not a recommendation to buy, sell or hold securities and the ratings are subject to revision or withdrawal at any time by the rating organization. Each rating should be evaluated independently of any other rating.
Capital Allocation Framework––Our capital allocation framework is primarily devised to enhance shareholder value and is based on three core pillars: growing our dividend, reinvesting in the business and making share repurchases after de-levering our balance sheet. See the Overview of Our Performance, Operating Environment, Strategy and OutlookOur Business and Strategy section within MD&A.
Our current and projected dividends provide a return to shareholders while maintaining sufficient capital to invest in growing our business. Our dividends are not restricted by debt covenants. While the dividend level remains a decision of Pfizer’s BOD and will continue to be evaluated in the context of future business performance, we currently believe that we can support future annual dividend increases, barring significant unforeseen events. On December 14, 2023, our BOD declared a first-quarter dividend of $0.42 per share, payable on March 1, 2024, to shareholders of record at the close of business on January 26, 2024. The first-quarter 2024 cash dividend will be our 341st consecutive quarterly dividend.
As of December 31, 2023, our remaining share-purchase authorization was approximately $3.3 billion.
Off-Balance Sheet Arrangements, Contractual, and Other Obligations––In the ordinary course of business, (i) we enter into off-balance sheet arrangements that may result in contractual and other obligations and (ii) in connection with the sale of assets and businesses and other transactions, we often indemnify our counterparties against certain liabilities that may arise in connection with the transaction or that are related to events and activities. For more information on guarantees and indemnifications, see Note 16B.
Additionally, certain of our co-promotion or license agreements give our licensors or partners the rights to negotiate for, or in some cases to obtain under certain financial conditions, co-promotion or other rights in specified countries with respect to certain of our products. Furthermore, collaboration, licensing or other R&D arrangements may give rise to potential milestone payments. Payments under these agreements generally become due and payable only upon the achievement of certain development, regulatory and/or commercialization milestones, which may span several years and which may never occur.
Our significant contractual and other obligations as of December 31, 2023 consisted of:
Long-term debt, including current portion (see Note 7D) and related interest payments;
Estimated cash payments related to the TCJA repatriation estimated tax liability (see Note 5). Estimated future payments related to the TCJA repatriation tax liability that will occur after December 31, 2023 total $6.0 billion, of which an estimated $1.5 billion is to be paid in the next twelve months and an estimated $4.5 billion is to be paid in periods thereafter. Our obligations may vary as a result of changes in our uncertain tax positions and/or availability of attributes such as foreign tax and other credit carryforwards;
Certain commitments totaling $5.2 billion, of which an estimated $1.3 billion is to be paid in the next twelve months, and $3.9 billion in periods thereafter (seeNote 16C);
Purchases of PP&E (seeNote 9). In 2024, we expect to spend approximately $3.7 billion on PP&E; and
Future minimum rental commitments under non-cancelable operating leases (see Note 15).
Global Economic Conditions––Venezuela, Argentina and Turkey operations function in a hyperinflationary economy. The impact to Pfizer is not considered material. See the Item 1A. Risk Factors––Global Operations section.
Market Risk––We are subject to foreign exchange risk, interest rate risk, and equity price risk. The objective of our financial risk management program is to minimize the impact of foreign exchange rate and interest rate movements on our earnings. We address such exposures through a combination of operational means and financial instruments. For more information on how we manage our foreign exchange and interest rate risks, see Notes 1F and 7E, as well as the Item 1A. Risk Factors—Global Operationssection for key currencies in which we operate. Our sensitivity analyses of such risks are discussed below.
Foreign Exchange Risk—The fair values of our financial instrument holdings are analyzed at year-end to determine their sensitivity to foreign exchange rate changes. In this analysis, holding all other assumptions constant and assuming that a change in one currency’s rate relative to the U.S. dollar would not have any effect on another currency’s rates relative to the U.S. dollar, if the dollar were to move against all other currencies by 10%, as of December 31, 2023, the expected impact on our net income would not be significant.
Interest Rate Risk—The fair values of our financial instrument holdings are analyzed at year-end to determine their sensitivity to interest rate changes. In this analysis, holding all other assumptions constant and assuming a parallel shift in the interest rate curve for all maturities and for all instruments, if there were a one hundred basis point change in interest rates as of December 31, 2023, the expected impact on our net income would not be significant.
Equity Price Risk––We hold long-term investments in equity securities with readily determinable fair values in life science companies as a result of certain business development transactions (see Note 7B). While we are holding such securities, we are subject to equity price risk, and this may increase the volatility of our income in future periods due to changes in the fair value of equity investments. From time to time, we will sell

Pfizer Inc.2023 Form 10-K48


such equity securities based on our business considerations, which may include limiting our price risk. Our equity securities with readily determinable fair values are analyzed at year-end to determine their sensitivity to equity price rate changes. In this sensitivity analysis, the expected impact on our net income would not be significant.
NEW ACCOUNTING STANDARDS
Recently Adopted Accounting Standards
See Note 1B.
Recently Issued Accounting Standards, Not Adopted as of December 31, 2023
Standard/DescriptionEffective DateEffect on the Financial Statements
In June 2022, the FASB issued final guidance to clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered when measuring fair value. Recognizing a contractual sale restriction as a separate unit of account is not permitted.
January 1, 2024, with early adoption permitted.The new guidance is consistent with our current policy, and it will not have an impact on our consolidated financial statements.
In November 2023, the FASB issued final guidance to improve transparency of segment disclosures. The final guidance requires the disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, other segment items by reportable segment and a description of its composition, and requires all current annual disclosures be provided in interim periods.
January 1, 2024 for annual reports and January 1, 2025 for interim reports. Early adoption is permitted.This new guidance will result in increased disclosures in the notes to our financial statements.
In December 2023, the FASB issued final guidance to improve income tax disclosures. The final guidance requires enhanced disclosures primarily related to existing rate reconciliation and income taxes paid information.
January 1, 2025, with early adoption permitted.This new guidance will result in increased disclosures in the notes to our financial statements.

ITEM 8.FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Information required by this item is incorporated by reference from the Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders
Pfizer Inc.:
Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheets of Pfizer Inc. and Subsidiary Companies (the Company) as of December 31, 2023 and 2022, the related consolidated statements of income, comprehensive income, equity, and cash flows for each of the years in the three-year period ended December 31, 2023, and the related notes (collectively, the consolidated financial statements). In our 2017 Financial Report and fromopinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2023, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 22, 2024 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matters
The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
Evaluation of the U.S. Medicare, Medicaid, and performance-based contract rebates accrual
As discussed in Note 1G to the consolidated financial statements, the Company records estimated deductions for Medicare, Medicaid, and performance-based contract rebates (collectively, U.S. rebates) as a reduction to gross product revenues. The accrual for U.S. rebates is recorded in the same period that the corresponding revenues are recognized. The length of time between when a sale is made and when the U.S. rebate is paid by the Company can be as long as one year, which increases the need for significant management judgment and knowledge of market conditions and practices in estimating the accrual.
We identified the evaluation of the U.S. rebates accrual as a critical audit matter because the evaluation of the product-specific experience ratio assumption involved especially challenging auditor judgment. The product-specific experience ratio assumption relates to estimating which of the Company’s revenue transactions will ultimately be subject to a related rebate.
The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s U.S. rebates accrual process related to the development of the product-specific experience ratio assumptions. We estimated the U.S. rebates accrual using internal information and historical data and compared the result to the Company’s estimated U.S. rebates accrual. We evaluated the Company’s ability to accurately estimate the accrual for U.S. rebates by comparing historically recorded accruals to the actual amount that was ultimately paid by the Company.
Evaluation of gross unrecognized tax benefits
As discussed in Notes 5D and 1Q, the Company’s tax positions are subject to audit by local taxing authorities in each respective tax jurisdiction, and the resolution of such audits may span multiple years. Since tax law is complex and often subject to varied interpretations and judgments, it is uncertain whether some of the Company’s tax positions will be sustained upon audit. As of December 31, 2023, the Company has recorded gross unrecognized tax benefits, excluding associated interest, of $4.8 billion.
We identified the evaluation of certain of the Company’s gross unrecognized tax benefits as a critical audit matter because a high degree of audit effort, including specialized skills and knowledge, and complex auditor judgment was required in evaluating the Company’s interpretation of tax law and its estimate of the ultimate resolution of its tax positions.
The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of an internal control over the Company’s liability for unrecognized tax position process related to (1) interpretation of tax law, (2) evaluation of which of the Company’s tax positions may not be sustained upon audit, and (3) estimation and recording of the gross

Pfizer Inc.2023 Form 10-K50


Report of Independent Registered Public Accounting Firm
unrecognized tax benefits. We involved tax and valuation professionals with specialized skills and knowledge who assisted in evaluating the Company’s interpretation of tax laws, including the assessment of transfer pricing practices in accordance with applicable tax laws and regulations. We inspected settlements with applicable taxing authorities, including assessing the expiration of statutes of limitations. We tested the calculation of the liability for uncertain tax positions, including an evaluation of the Company’s assessment of the technical merits of tax positions and estimates of the amount of tax benefits expected to be sustained.
Evaluation of product liability and other product-related litigation
As discussed in Notes 1S and 16 to the consolidated financial statements, the Company is involved in product liability and other product-related litigation, which can include personal injury, consumer, off-label promotion, securities, antitrust and breach of contract claims, among others. Certain of these pending product and other product-related legal proceedings could result in losses that could be substantial. The accrued liability and/or disclosure for the pending product liability and other product-related legal proceedings requires a complex series of judgments by the Company about future events, which involves a number of uncertainties.
We identified the evaluation of product liability and other product-related litigation as a critical audit matter. Challenging auditor judgment was required to evaluate the Company’s judgments about future events and uncertainties.
The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s product liability and other product-related litigation processes, including controls related to (1) the evaluation of information from external and internal legal counsel, (2) forward-looking expectations, and (3) new legal proceedings, or other legal proceedings not currently reserved or disclosed. We read letters received directly from the Company’s external and internal legal counsel that described the Company’s probable or reasonably possible legal contingency to pending product liability and other product-related legal proceedings. We inspected the Company’s minutes from meetings of the Audit Committee, which included the status of key litigation matters. We evaluated the Company’s ability to estimate its monetary exposure to pending product and other product-related legal proceedings by comparing historically recorded liabilities to actual monetary amounts incurred upon resolution of prior legal matters. We analyzed relevant publicly available information about the Company, its competitors, and the industry.
Evaluation of the fair value measurement of the developed technology rights and in-process research and development intangible assets acquired in the Seagen business combination
As discussed in Note 2A to the consolidated financial statements, on December 14, 2023, the Company acquired Seagen Inc. and its subsidiaries (Seagen). The total fair value of consideration transferred was $44.2 billion. Of that, the Company provisionally recorded $7.5 billion of developed technology rights with an estimated weighted-average life of approximately 18 years and $20.8 billion of in-process research and development (IPR&D).
We identified the evaluation of the fair value measurement of the acquired developed technology rights and IPR&D as a critical audit matter. A high degree of subjective auditor judgment was required to evaluate certain key assumptions used to estimate the acquisition-date fair value of the acquired developed technology rights and IPR&D. Specifically, the key assumptions for certain IPR&D assets, including revenue growth rates, probability of technical and regulatory success (PTRS) rates, and the discount rate, and the key assumptions for certain developed technology rights, including revenue growth rates and the discount rate, represented subjective determinations of future market and economic conditions. Changes to those assumptions could have had a significant effect on the determination of the fair value measurements.
The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company’s acquisition-date valuation process, including controls related to the development of the key assumptions for certain IPR&D assets and developed technology rights. We performed sensitivity analyses over the key assumptions for certain IPR&D assets and developed technology rights to assess the impact of changes in those key assumptions on the Company’s determination of the fair value of the IPR&D and developed technology rights, respectively. We evaluated the reasonableness of the Company’s forecasted revenue growth rates by comparing them to historical results for comparable products and peer companies, analyst expectations, and industry related third-party data. Further, we evaluated the PTRS rates for certain IPR&D assets by considering the phase of development of the clinical projects and the Company's history of obtaining regulatory approval and comparing them to PTRS rates derived from analyst reports and other industry related third-party data. We evaluated the data sources used by management in determining the key assumptions for certain IPR&D assets and developed technology rights by comparing to industry standards and evidence obtained in other areas of the audit.In addition, we involved valuation professionals with specialized skills and knowledge, who assisted in:
(1)evaluating the discount rates used by the Company for certain IPR&D and developed technology rights by comparing them against discount rate ranges that were independently developed using publicly available market data for comparable entities
(2)testing the source information underlying the determination of the discount rates.

We have not been able to determine the specific year that we or our predecessor firms began serving as the Company’s auditor, however, we are aware that we or our predecessor firms have served as the Company’s auditor since at least 1942.

Notes to Consolidated Financial Statements
Pfizer Inc. and Subsidiary Companies

Note 1. Basis of Presentation and Significant Accounting Policies
A. Basis of Presentation
The consolidated financial statements include the accounts of our parent company and all subsidiaries and are prepared in accordance with U.S. GAAP. The decision of whether or not to consolidate an entity for financial reporting purposes requires consideration of majority voting interests, as well as effective economic or other control over the entity. Typically, we do not seek control by means other than voting interests. For subsidiaries operating outside the U.S., the financial information is included as of and for the year ended November 30 for each year presented. Pfizer's fiscal year-end for U.S. subsidiaries is as of and for the year ended December 31 for each year presented. All significant transactions among our subsidiaries have been eliminated.
In 2023, we managed our commercial operations through two operating segments, each led by a single manager: Biopharma and Business Innovation. Biopharma is the only reportable segment. See Note 17.
On December 14, 2023, we completed the acquisition of Seagen. On December 31, 2021, we completed the sale of our Meridian subsidiary, the manufacturer of EpiPen and other auto-injector products. In addition, other acquisitions and business development activities completed in 2023, 2022 and 2021 impacted financial results in the periods presented. See Note 2.
We have made certain reclassification adjustments to conform prior-period amounts to the current presentation. Certain amounts in the consolidated financial statements and associated notes may not add due to rounding. All percentages have been calculated using unrounded amounts.
B. New Accounting Standards Adopted in 2023
On January 1, 2023, we adopted a new accounting standard for supplier finance programs which requires increased disclosures in the notes to our financial statements. See Note 8C.
In the second quarter of 2023, we adopted new accounting standards on reference rate reform that provide temporary optional expedients and exceptions to the guidance for contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate that were discontinued after June 30, 2023. We applied certain of the optional expedients related to hedge accounting relationships. The main purpose of the expedients is to allow hedge accounting to continue uninterrupted and make it easier to apply the requirements to maintain hedge accounting during the transition period through December 31, 2024.
C. Estimates and Assumptions
In preparing these financial statements, we use certain estimates and assumptions that affect reported amounts and disclosures. These estimates and assumptions can impact all elements of our financial statements. For example, in the consolidated statements of income, estimates are used when accounting for deductions from revenues, determining the cost of inventory that is sold, allocating cost in the form of depreciation and amortization, and estimating restructuring charges and the impact of contingencies, as well as determining provisions for taxes on income. On the consolidated balance sheets, estimates are used in determining the valuation and recoverability of assets, and in determining the reported amounts of liabilities, all of which also impact the consolidated statements of income. Certain estimates of fair value and amounts recorded in connection with acquisitions, revenue deductions, impairment reviews, restructuring-associated charges, investments and financial instruments, valuation allowances, pension and postretirement benefit plans, contingencies, share-based compensation, and other calculations can result from a complex series of judgments about future events and uncertainties and can rely heavily on estimates and assumptions.
Our estimates are often based on complex judgments and assumptions that we believe to be reasonable, but that can be inherently uncertain and unpredictable. If our estimates and assumptions are not representative of actual outcomes, our results could be materially impacted. As future events and their effects cannot be determined with precision, our estimates and assumptions may prove to be incomplete or inaccurate, or unanticipated events and circumstances may occur that might cause us to change those estimates and assumptions. We are subject to risks and uncertainties that may cause actual results to differ from estimated amounts, such as changes in the healthcare environment, competition, litigation, legislation and regulations. We regularly evaluate our estimates and assumptions using historical experience and expectations about the future. We adjust our estimates and assumptions when facts and circumstances indicate the need for change.
D. Acquisitions
Our consolidated financial statements include the operations of acquired businesses after the completion of the acquisitions. We account for acquired businesses using the acquisition method of accounting, which requires, among other things, that most assets acquired and liabilities assumed be recognized at their estimated fair values as of the acquisition date and that the fair value of acquired IPR&D be recorded on the balance sheet. Transaction costs are expensed as incurred. Any excess of the consideration transferred over the assigned values of the net assets acquired is recorded as goodwill. When we acquire net assets that do not constitute a business, as defined in U.S. GAAP, no goodwill is recognized and acquired IPR&D is expensed in Acquired in-process research and development expenses.
Contingent consideration in a business combination is included as part of the acquisition cost and is recognized at fair value as of the acquisition date. Fair value is generally estimated by using a probability-weighted discounted cash flow approach. See Note 16D. Any liability resulting from contingent consideration is remeasured to fair value at each reporting date until the contingency is resolved. These changes in fair value are recognized in earnings in Other (income)/deductions––net.
E. Fair Value
We measure certain assets and liabilities at fair value, either upon initial recognition or for subsequent accounting or reporting. We estimate fair value using an exit price approach, which requires, among other things, that we determine the price that would be received to sell an asset or paid to transfer a liability in an orderly market. The determination of an exit price is considered from the perspective of market participants,

Pfizer Inc.2023 Form 10-K58


Notes to Consolidated Financial Statements
Pfizer Inc. and Subsidiary Companies
considering the highest and best use of non-financial assets and, for liabilities, assuming that the risk of non-performance will be the same before and after the transfer.
When estimating fair value, depending on the nature and complexity of the asset or liability, we may use one or all of the following techniques:
Income approach, which is based on the present value of a future stream of net cash flows.
Market approach, which is based on market prices and other information from market transactions involving identical or comparable assets or liabilities.
Cost approach, which is based on the cost to acquire or construct comparable assets, less an allowance for functional and/or economic obsolescence.
Our fair value methodologies depend on the following types of inputs:
Quoted prices for identical assets or liabilities in active markets (Level 1 inputs).
Quoted prices for similar assets or liabilities in active markets, or quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are directly or indirectly observable, or inputs that are derived principally from, or corroborated by, observable market data by correlation or other means (Level 2 inputs).
Unobservable inputs that reflect estimates and assumptions (Level 3 inputs).
The following inputs and valuation techniques are used to estimate the fair value of our financial assets and liabilities:
Available-for-sale debt securities—third-party matrix-pricing model that uses significant inputs derived from or corroborated by observable market data and credit-adjusted yield curves.
Equity securities with readily determinable fair values—quoted market prices and observable NAV prices.
Derivative assets and liabilities—third-party matrix-pricing model that uses inputs derived from or corroborated by observable market data. Where applicable, these models use market-based observable inputs, including interest rate yield curves to discount future cash flow amounts, and forward and spot prices for currencies. The credit risk impact to our derivative financial instruments was not significant.
Money market funds—observable NAV prices.
We periodically review the methodologies, inputs and outputs of third-party pricing services for reasonableness. Our procedures can include, for example, referencing other third-party pricing models, monitoring key observable inputs (like benchmark interest rates) and selectively performing test-comparisons of values with actual sales of financial instruments.
F. Foreign Currency Translation
For most of our international operations, local currencies have been determined to be the functional currencies. We translate functional currency assets and liabilities to their U.S. dollar equivalents at exchange rates in effect as of the balance sheet date and income and expense amounts at average exchange rates for the period. The U.S. dollar effects that arise from changing translation rates are recorded in Other comprehensive income/(loss). The effects of converting non-functional currency monetary assets and liabilities into the functional currency are recorded in Other (income)/deductions––net. For operations in highly inflationary economies, we translate monetary items at rates in effect as of the balance sheet date, with translation adjustments recorded in Other (income)/deductions––net, and we translate non-monetary items at historical rates.
G. Revenues and Trade Accounts Receivable
Revenue Recognition––We record revenues from product sales when there is a transfer of control of the product from us to the customer. We typically determine transfer of control based on when the product is shipped or delivered and title passes to the customer. For certain contracts, the finished product may temporarily be stored at our or our third-party subcontractors’ locations under a bill-and-hold arrangement. Revenue is recognized on bill-and-hold arrangements at the point in time when the customer obtains control of the product and all of the following criteria have been met: the arrangement is substantive; the product is identified separately as belonging to the customer; the product is ready for physical transfer to the customer; and we do not have the ability to use the product or direct it to another customer. In bill-and-hold arrangements which are part of the U.S. Government Strategic National Stockpile, we recognize revenue for the product sale when the product is initially placed into the Stockpile and we provide a rotation service to maintain an agreed upon level of shelf life for product in the stockpile. In determining when the customer obtains control of the product, we consider certain indicators, including whether we have a present right to payment from the customer, whether title and/or significant risks and rewards of ownership have transferred to the customer and whether customer acceptance has been received.
In the fourth quarter of 2023, we began reporting Product revenues and Alliance revenues as separate line items in our consolidated statements of income. Prior-period amounts have been reclassified to conform to the current presentation.
Our Sales Contracts––Sales on credit are typically under short-term contracts. Collections are based on market payment cycles common in various markets, with shorter cycles in the U.S. Salesare adjusted for sales allowances, chargebacks, rebates and sales returns and cash discounts. Sales returns may occur due to LOE, product recalls or a changing competitive environment.
Deductions from Revenues––Our gross product revenues are subject to a variety of deductions, which generally are estimated and recorded in the same period that the revenues are recognized. Such variable consideration represents chargebacks, rebates, sales allowances and sales returns. These deductions represent estimates of the related obligations and, as such, knowledge and judgment is required when estimating the impact of these product revenue deductions on gross sales for a reporting period.
Provisions for pharmaceutical sales returns––Provisions are based on a calculation for each market that incorporates the following, as appropriate: local returns policies and practices; historical returns as a percentage of sales; an understanding of the reasons for past returns; estimated shelf life by product; an estimate of the amount of time between shipment and return or lag time; and any other factors that could

Pfizer Inc.2023 Form 10-K59


Notes to Consolidated Financial Statements
Pfizer Inc. and Subsidiary Companies
impact the estimate of future returns, such as LOE, product recalls or a changing competitive environment. Generally, returned products are destroyed, and customers are refunded the sales price in the form of a credit.
We record sales incentives as a reduction of revenues at the time the related revenues are recorded or when the incentive is offered, whichever is later. We estimate the cost of our sales incentives based on our historical experience with similar incentives programs to predict customer behavior.
The following outlines our common sales arrangements:
Customers––Our prescription biopharmaceutical products, with the exception of Paxlovid in 2022 and 2023, are sold principally to wholesalers, but we also sell directly to retailers, hospitals, clinics, government agencies and pharmacies. In 2022 and 2023, we principally sold Paxlovid globally to government agencies. Our vaccines in the U.S. are primarily sold directly to the federal government (including the CDC), wholesalers, individual provider offices, retail pharmacies and integrated delivery systems. Our vaccines outside the U.S. are primarily sold to government and non-government institutions. Prescription pharmaceutical products that ultimately are used by patients are generally covered under governmental programs, managed care programs and insurance programs, including those managed through PBMs, and are subject to sales allowances and/or rebates payable directly to those programs. Those sales allowances and rebates are generally negotiated, but government programs may have legislated amounts by type of product (e.g., patented or unpatented).
Specifically:
In the U.S., we sell our products principally to distributors and hospitals. We also have contracts with managed care programs or PBMs and legislatively mandated contracts with the federal and state governments under which we provide rebates based on medicines utilized by the lives they cover. We record provisions for Medicare, Medicaid, and performance-based contract pharmaceutical rebates based upon our experience ratio of rebates paid and actual prescriptions written during prior periods. We apply the experience ratio to the respective period’s sales to determine the rebate accrual and related expense. This experience ratio is evaluated regularly to ensure that the historical trends are as current as practicable. We estimate discounts on branded prescription drug sales to Medicare Part D participants in the Medicare “coverage gap,” also known as the “doughnut hole,” based on the historical experience of beneficiary prescriptions and consideration of the utilization that is expected to result from the discount in the coverage gap. We evaluate this estimate regularly to ensure that the historical trends and future expectations are as current as practicable. For performance-based contract rebates, we also consider current contract terms, such as changes in formulary status and rebate rates.
Outside the U.S., the majority of our pharmaceutical sales allowances are contractual or legislatively mandated and our estimates are based on actual invoiced sales within each period, which reduces the risk of variations in the estimation process. In certain European countries, rebates are calculated on the government’s total unbudgeted pharmaceutical spending or on specific product sales thresholds and we apply an estimated allocation factor against our actual invoiced sales to project the expected level of reimbursement. We obtain third-party information that helps us to monitor the adequacy of these accruals.
Provisions for pharmaceutical chargebacks (primarily reimbursements to U.S. wholesalers for honoring contracted prices and legislated discounts to third parties) closely approximate actual amounts incurred, as we settle these deductions generally within two to five weeks of incurring the liability.
We recorded direct product sales and/or Alliance revenues of more than $1 billion for each of nine products in 2023, for each of ten products in 2022 and for each of nine products in 2021. In the aggregate, these direct product sales and/or Alliance revenues represented 64%, 82% and 75% of our Total revenues in 2023, 2022 and 2021, respectively. See Note 17C. The loss or expiration of intellectual property rights can have a significant adverse effect on our revenues as our contracts with customers will generally be at lower selling prices and lower volumes due to added generic competition. We generally provide for higher sales returns during the period in which individual markets begin to near the loss or expiration of intellectual property rights.
Our accruals for Medicare, Medicaid and related state program and performance-based contract rebates, chargebacks, sales allowances and sales returns and cash discounts are as follows:
  As of December 31,
(MILLIONS)20232022
Reserve against Trade accounts receivable, less allowance for doubtful accounts
$1,770 $1,200 
Other current liabilities:
Accrued rebates5,546 4,479 
Other accruals902 430 
Other noncurrent liabilities796 612 
Total accrued rebates and other sales-related accruals$9,014 $6,722 
Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from Product revenues.
Trade Accounts Receivable—Trade accounts receivable are stated at their net realizable value. The allowance for credit losses reflects our best estimate of expected credit losses of the receivables portfolio determined on the basis of historical experience, current information, and forecasts of future economic conditions. In developing the estimate for expected credit losses, trade accounts receivables are segmented into pools of assets depending on market (U.S. versus international), delinquency status, and customer type (high risk versus low risk and government versus non-government), and fixed reserve percentages are established for each pool of trade accounts receivables.
In determining the reserve percentages for each pool of trade accounts receivables, we considered our historical experience with certain customers and customer types, regulatory and legal environments, country and political risk, and other relevant current and future forecasted macroeconomic factors. These credit risk indicators are monitored on a quarterly basis to determine whether there have been any changes in the economic environment that would indicate the established reserve percentages should be adjusted, and are considered on a regional basis to reflect more geographic-specific metrics. Additionally, write-offs and recoveries of customer receivables are tracked against collections

Pfizer Inc.2023 Form 10-K60


Notes to Consolidated Financial Statements
Pfizer Inc. and Subsidiary Companies
on a quarterly basis to determine whether the reserve percentages remain appropriate. When management becomes aware of certain customer-specific factors that impact credit risk, specific allowances for these known troubled accounts are recorded. Trade accounts receivable are written off after all reasonable means to collect the full amount (including litigation, where appropriate) have been exhausted.
During 2023 and 2022, additions to the allowance for credit losses, write-offs and recoveries of customer receivables were not material to our consolidated financial statements.

H. Collaborative Arrangements
Payments to and from our collaboration partners are presented in our consolidated statements of income based on the nature of the arrangement (including its contractual terms), the nature of the payments and applicable accounting guidance. Under co-commercialization agreements, we record the amounts received for our share of gross profits from our collaboration partners as Alliance revenues, when our collaboration partners are the principal in the transaction and we receive a share of their net sales or profits. Alliance revenues are recorded as we perform co-promotion activities for the collaboration and the collaboration partners sell the products to their customers. The related expenses for selling and marketing these products including reimbursements to or from our collaboration partners for these costs are included in Selling, informational and administrative expenses. In collaborative arrangements where we manufacture a product for our collaboration partners, we record revenues when we transfer control of the product to our collaboration partners. In collaboration arrangements where we are the principal in the transaction, we record amounts paid to collaboration partners for their share of net sales or profits earned, and all royalty payments to collaboration partners as Cost of sales. Royalty payments received from collaboration partners are included in Other (income)/deductions—net.
Reimbursements to or from our collaboration partners for development costs are typically recorded in Research and development expenses. Upfront payments and pre-approval milestone payments due from us to our collaboration partners in development stage collaborations are recorded as Acquiredin-process research and development expenses. Milestone payments due from us to our collaboration partners after regulatory approval has been attained for a medicine are recorded in Identifiable intangible assets—developed technology rights. Upfront and pre-approval milestone payments earned from our collaboration partners by us are recognized in Other (income)/deductions—net over the development period for the products, when our performance obligations include providing R&D services to our collaboration partners. Upfront, pre-approval and post-approval milestone payments earned by us may be recognized in Other (income)/deductions—net immediately when earned or over other periods depending upon the nature of our performance obligations in the applicable collaboration. Where the milestone event is regulatory approval for a medicine, we generally recognize milestone payments due to us in the transaction price when regulatory approval in the applicable jurisdiction has been attained. We may recognize milestone payments due to us in the transaction price earlier than the milestone event in certain circumstances when recognition of the income would not be probable of a significant reversal.
I. Cost of Sales and Inventories
Inventories are recorded at the lower of cost or net realizable value. The cost of finished goods, work in process and raw materials is determined using average actual cost. We regularly review our inventories for impairment and reserves are established when necessary. Inventories that are not expected to be sold within 12 months are classified as Other noncurrent assets. See Note 8A.
J. Selling, Informational and Administrative Expenses
Selling, informational and administrative costs are expensed as incurred. Among other things, these expenses include the internal and external costs of marketing, advertising, shipping and handling, digital and legal defense. Advertising expenses totaled approximately $3.7 billion in 2023, $2.8 billion in 2022 and $2.0 billion in 2021. Production costs are expensed as incurred and the costs of TV, radio, and other electronic media and publications are expensed when the related advertising occurs.
K. Research and Development Expenses
R&D costs are expensed as incurred. These expenses include the costs of our proprietary R&D efforts, as well as R&D activities performed in connection with certain licensing arrangements.
L. Acquired In-Process Research and Development Expenses
Before a compound receives regulatory approval, we record upfront and milestone payments we make to third parties under licensing and collaboration arrangements as expense. Upfront payments are recorded when incurred, and milestone payments are recorded when the specific milestone has been achieved. Once a compound receives regulatory approval, we record any milestone payments in Identifiable intangible assets, less accumulated amortization and, unless the asset is determined to have an indefinite life, we typically amortize the payments on a straight-line basis over the remaining agreement term or the expected product life cycle, whichever is shorter. Acquired in-process research and development expenses includes costs incurred in connection with (a) all upfront and milestone payments on collaboration and in-license agreements, including premiums on equity securities and (b) asset acquisitions of acquired IPR&D.
M. Amortization of Intangible Assets, Depreciation and Certain Long-Lived Assets
Long-lived assets include:
Property, plant and equipment, less accumulated depreciation—These assets are recorded at cost, including any significant improvements after purchase, less accumulated depreciation. Property, plant and equipment assets, other than land and construction in progress, are depreciated on a straight-line basis over the estimated useful life of the individual assets. Depreciation begins when the asset is ready for its intended use. For tax purposes, accelerated depreciation methods are used as allowed by tax laws.
Identifiable intangible assets, less accumulated amortization—These assets are recorded at fair value at acquisition. Intangible assets with finite livesare amortized on a straight-line basis over their estimated useful lives. Intangible assets with indefinite lives are not amortized until a useful life can be determined.

Pfizer Inc.2023 Form 10-K61


Notes to Consolidated Financial Statements
Pfizer Inc. and Subsidiary Companies
Goodwill—Goodwill represents the excess of the consideration transferred for an acquired business over the assigned values of its net assets. Goodwill is not amortized.
Amortization of finite-lived acquired intangible assets is included in Amortization of intangible assets.
We review our long-lived assets for impairment indicators throughout the year. We perform impairment testing for indefinite-lived intangible assets and goodwill at least annually and for all other long-lived assets whenever impairment indicators are present. When necessary, we record impairments of long-lived assets for the amount by which the fair value is less than the carrying value of these assets.
Specifically:
For finite-lived intangible assets, such as developed technology rights, and for other long-lived assets, such as property, plant and equipment, whenever impairment indicators are present, we calculate the undiscounted value of the projected cash flows for the asset, or asset group, and compare this estimated amount to the carrying amount. If the carrying amount is greater, we record an impairment loss for the excess of book value over fair value. In addition, in all cases of an impairment review, we reevaluate the remaining useful lives of the assets and modify them, as appropriate.
For indefinite-lived intangible assets, such as brands and IPR&D assets, when necessary, we determine the fair value of the asset and record an impairment loss, if any, for the excess of book value over fair value. In addition, in all cases of an impairment review other than for IPR&D assets, we re-evaluate whether continuing to characterize the asset as indefinite-lived is appropriate.
For goodwill, when necessary, we determine the fair value of each reporting unit and record an impairment loss, if any, for the excess of the book value of the reporting unit over the implied fair value.
N. Restructuring Charges and Other Costs Associated with Acquisitions and Cost-Reduction/Productivity Initiatives

We incur restructuring charges in connection with acquisitions when we implement plans to restructure and integrate the acquired operations or in connection with our cost-reduction and productivity initiatives.
In connection with acquisition activity, we typically incur costs associated with executing the transactions, integrating the acquired operations (which may include expenditures for consulting and the integration of systems and processes), and restructuring the combined company (which may include charges related to employees, assets and activities that will not continue in the combined company); and
In connection with our cost-reduction/productivity initiatives, we typically incur costs and charges for site closings and other facility rationalization actions, workforce reductions and the expansion of shared services, including the development of global systems.
Included in Restructuring charges and certain acquisition-related costs are all restructuring charges, as well as certain other costs associated with acquiring and integrating an acquired company. If the restructuring action results in a change in the estimated useful life of an asset, that incremental impact is classified in Cost of sales, Selling, informational and administrative expenses and/or Research and development expenses, as appropriate. Employee termination costs are generally recorded when the actions are probable and estimable and include accrued severance benefits, pension and postretirement benefits, many of which may be paid out during periods after termination.Transaction costs, such as banking, legal, accounting and other similar costs incurred in connection with a business acquisition are expensed as incurred.
Our business and platform functions may be impacted by these actions, including sales and marketing, manufacturing and R&D, as well as our corporate enabling functions.
O. Cash Equivalents and Statement of Cash Flows
Cash equivalents include items almost as liquid as cash, such as certificates of deposit and time deposits with maturity periods of three months or less when purchased. If items meeting this definition are part of a larger investment pool, we classify them as Short-term investments.
Cash flows for financial instruments designated as fair value or cash flow hedges may be included in operating, investing or financing activities, depending on the classification of the items being hedged. Cash flows for financial instruments designated as net investment hedges are classified according to the nature of the hedging instrument. Cash flows for financial instruments that do not qualify for hedge accounting treatment are classified according to their purpose and accounting nature.
P. Investments and Derivative Financial Instruments
The classification of an investment depends on the nature of the investment, our intent and ability to hold the investment, and the degree to which we may exercise influence. Our investments are primarily comprised of the following:
Public equity securities with readily determinable fair values, which are carried at fair value, with changes in fair value reported in Other (income)/deductions—net.
Available-for-sale debt securities, which are carried at fair value, with changes in fair value reported in Other comprehensive income/(loss) until realized.
Held-to-maturity debt securities, which are carried at amortized cost.
Private equity securities without readily determinable fair values and where we have no significant influence are measured at cost minus any impairment and plus or minus adjustments resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer.
For equity investments in common stock or in-substance common stock where we have significant influence over the financial and operating policies of the investee, we use the equity-method of accounting. Under the equity-method, we record our share of the investee’s income and expenses in Other (income)/deductions—net. The excess of the cost of the investment over our share of the underlying equity in the net assets of the investee as of the acquisition date is allocated to the identifiable assets and liabilities of the investee, with any remaining

Pfizer Inc.2023 Form 10-K62


Notes to Consolidated Financial Statements
Pfizer Inc. and Subsidiary Companies
excess amount allocated to goodwill. Such investments are initially recorded at cost, which is the fair value of consideration paid and typically does not include contingent consideration.
Realized gains or losses on sales of investments are determined by using the specific identification cost method.
We regularly evaluate all of our financial assets for impairment. For investments in debt and equity, if and when a decline in fair value is determined, an impairment charge is recorded and a new cost basis in the investment is established. For equity-method investments, an impairment charge is recorded only if and when a decline in fair value is determined to be other-than-temporary.
Derivative financial instruments are carried at fair value in certain balance sheet categories (see Note 7A), with changes in fair value reported in net income or, for certain qualifying hedging relationships, in Other comprehensive income/(loss) (see Note 7E).
Q. Tax Assets and Liabilities and Income Tax Contingencies
Tax Assets and Liabilities––Current tax assets primarily include (i) tax effects for intercompany transfers of inventory within our combined group, which are recognized in the consolidated statements of income when the inventory is sold to a third party and (ii) income tax receivables that are expected to be recovered either via refunds from taxing authorities or reductions to future tax obligations.
Deferred tax assets and liabilities are recognized for the expected future tax consequences of differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates and laws. We provide a valuation allowance when we believe that our deferred tax assets are not recoverable based on an assessment of estimated future taxable income that incorporates ongoing, prudent and feasible tax-planning strategies, that would be implemented, if necessary, to realize the deferred tax assets. Amounts recorded for valuation allowances requires judgments about future income which can depend heavily on estimates and assumptions. All deferred tax assets and liabilities within the same tax jurisdiction are presented as a net amount in the noncurrent section of our consolidated balance sheet.
The TCJA subjects a U.S. shareholder to current tax on global intangible low-taxed income earned by certain foreign subsidiaries. The FASB Staff Q&A, Topic 740, No. 5, Accounting for Global Intangible Low-Taxed Income, states that we are permitted to make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as global intangible low-taxed income in future years or provide for the tax expense related to such income in the year the tax is incurred. We elected to recognize deferred taxes for temporary differences expected to reverse as global intangible low-taxed income in future years.
Other non-current tax assets primarily represent our estimate of the potential tax benefits in one tax jurisdiction that could result from the payment of income taxes in another tax jurisdiction. These potential benefits generally result from cooperative efforts among taxing authorities, as required by tax treaties to minimize double taxation, commonly referred to as the competent authority process. The recoverability of these assets, which we believe to be more likely than not, is dependent upon the actual payment of taxes in one tax jurisdiction and, in some cases, the successful petition for recovery in another tax jurisdiction.
Other taxes payable as of December 31, 2023 and 2022 include liabilities for uncertain tax positions and the noncurrent portion of the repatriation tax liability for which we elected payment over eight years through 2026. See Note 5D for uncertain tax positions and Note 5A for the repatriation tax liability and other estimates and assumptions in connection with the TCJA.
Income Tax Contingencies––We account for income tax contingencies using a benefit recognition model. If we consider that a tax position is more likely than not to be sustained upon audit, based solely on the technical merits of the position, we recognize all or a portion of the benefit. We measure the benefit by determining the amount that is greater than 50% likely of being realized upon settlement, presuming that the tax position is examined by the taxing authority with full knowledge of all relevant information.
We regularly monitor our position and subsequently recognize the unrecognized tax benefit: (i) if there are changes in tax law, analogous case law or there is new information that sufficiently raise the likelihood of prevailing on the technical merits of the position to “more likely than not”; (ii) if the statute of limitations expires; or (iii) if there is a completion of an audit resulting in a favorable settlement of that tax year with the appropriate agency. Liabilities for uncertain tax positions are classified as current only when we expect to pay cash within the next 12 months. Interest and penalties, if any, are recorded in Provision/(benefit) for taxes on income and are classified on our consolidated balance sheet with the related tax liability.
Our assessments are based on estimates and assumptions that have been deemed reasonable by management, but our estimates of unrecognized tax benefits and potential tax benefits may not be representative of actual outcomes, and variation from such estimates could materially affect our financial statements in the period of settlement or when the statutes of limitations expire, as we treat these events as discrete items in the period of resolution.
R. Pension and Postretirement Benefit Plans
The majority of our employees worldwide are covered by defined benefit pension plans, defined contribution plans or both. In the U.S., we have both IRC-qualified and supplemental (non-qualified) defined benefit plans and defined contribution plans, as well as other postretirement benefit plans consisting primarily of medical insurance for retirees and their eligible dependents. Net periodic pension and postretirement benefit costs other than the service costs are recognized in Other (income)/deductions—net. We immediately recognize actuarial gains and losses arising from the remeasurement of our pension and postretirement plans (mark-to-market accounting). Each time a pension or postretirement plan is remeasured, the actuarial gain or loss is recognized immediately and classified as Other (income)/deductions––net. We recognize the overfunded or underfunded status of each of our defined benefit plans as an asset or liability. The obligations are generally measured at the actuarial present value of all benefits attributable to employee service rendered, as provided by the applicable benefit formula. Our pension and other postretirement obligations may be determined using assumptions such as discount rate, expected annual rate of return on plan assets, expected employee turnover and participant mortality. For our pension plans, the obligation may also include assumptions as to future compensation levels. For our other postretirement benefit plans, the obligation may include assumptions as to the expected cost of providing medical insurance benefits, as well as the extent to which those costs are shared with the employee or others (such as governmental programs). Plan assets are measured at fair value.

Pfizer Inc.2023 Form 10-K63


Notes to Consolidated Financial Statements
Pfizer Inc. and Subsidiary Companies
S. Legal and Environmental Contingencies
We and certain of our subsidiaries are subject to numerous contingencies arising in the ordinary course of business, such as patent litigation, product liability and other product-related litigation, commercial and other asserted or unasserted matters, environmental claims and proceedings, government investigations and guarantees and indemnifications. In assessing contingencies related to legal and environmental proceedings that are pending against the Company, or unasserted claims that are probable of being asserted, we record accruals for these contingencies to the extent that we conclude that a loss is both probable and reasonably estimable. If some amount within a range of loss appears to be a better estimate than any other amount within the range, we accrue that amount. Alternatively, when no amount within a range of loss appears to be a better estimate than any other amount, we accrue the lowest amount in the range. We record anticipated recoveries under existing insurance contracts when recovery is assured.
T. Share-Based Payments
Our compensation programs can include share-based payments. Generally, grants under share-based payment programs are accounted for at fair value and these fair values are generally amortized on a straight-line basis or on an accelerated attribution approach over the vesting terms with the related costs recorded in Cost of sales, Selling, informational and administrative expenses and/or Research and development expenses, as appropriate.
Note 2. Acquisitions, Divestitures, Equity-Method Investments, Licensing Arrangement, Collaborative Arrangements and Research and Development Arrangement

A. Acquisitions
Seagen––On December 14, 2023 (the acquisition date), we acquired Seagen, a global biotechnology company that discovers, develops and commercializes transformative cancer medicines, for $229 per share in cash. The total fair value of the consideration transferred was $44.2 billion ($43.4 billion, net of cash acquired). In addition, in connection with the acquisition $476 million in post-closing compensation expense for Seagen employee incentive awards was recorded in Restructuring charges and certain acquisition-related costs (see Note 3). The combination of local Pfizer and Seagen entities may be pending in various jurisdictions and integration is subject to completion of various local legal and regulatory steps.
Seagen’s principal business was the development, manufacture, marketing and distribution of targeted cancer therapeutics, primarily using antibody-drug conjugate technology. Seagen’s portfolio includes four approved medicines as well as a pipeline of product candidates. Clinical development programs are ongoing for each of these approved medicines for potential new or expanded indications and for several product candidates. We believe our acquisition of Seagen will strengthen our oncology capabilities by allowing us to combine Seagen’s antibody-drug conjugate technology with the resources and scale of the Pfizer enterprise and to advance more potential breakthroughs to patients with cancer.
The following table summarizes the provisional amounts recognized for assets acquired and liabilities assumed as of the acquisition date. The estimated values are not yet finalized (see below) and are subject to change, which could be significant. We will finalize the amounts recognized as we obtain the information necessary to complete the analyses. We expect to finalize these amounts as soon as possible but no later than one year from the acquisition date.

(b)Comprised of $1.0 billion current inventories and $3.1 billion noncurrent inventories.
(c)Comprised mainly of $7.5 billion of finite-lived developed technology rights with an estimated weighted-average life of approximately 18 years.
(d)As of the acquisition date, included primarily in Noncurrent deferred tax liabilities.
The following items are subject to change:
Amounts for certain balances included in working capital (excluding inventories), and certain legal contingencies, pending receipt of certain information that could affect provisional amounts recorded. We do not believe any adjustments for legal contingencies will have a material impact on our consolidated financial statements.
Amounts for identifiable intangible assets, inventories, contractual commitments, PP&E, and operating lease ROU assets and liabilities, pending finalization of valuation efforts, the completion of certain physical inventory counts and the confirmation of the physical existence and condition of certain PP&E assets.

Pfizer Inc.2023 Form 10-K64


Notes to Consolidated Financial Statements
Pfizer Inc. and Subsidiary Companies
Amounts for income tax assets, receivables and liabilities, pending the filing of Seagen’s pre-acquisition tax returns and the receipt of information, including but not limited to that from taxing authorities, which may change certain estimates and assumptions used.
As of the acquisition date, the fair value of accounts receivable approximated the book value acquired. The gross contractual amount receivable was $597 million.
In the ordinary course of business, Seagen may incur liabilities for environmental, legal and tax matters, as well as guarantees and indemnifications. These matters may include contingencies. Except as specifically excluded by the relevant accounting standard, contingencies are required to be measured at fair value as of the acquisition date if the acquisition-date fair value of the asset or liability arising from a contingency can be determined. If the acquisition-date fair value of the asset or liability cannot be determined, the asset or liability would be recognized at the acquisition date if both of the following criteria are met: (i) it is probable that an asset existed or that a liability had been incurred at the acquisition date, and (ii) the amount of the asset or liability can be reasonably estimated.
Environmental Matters—In the ordinary course of business, Seagen may incur liabilities for environmental matters such as remediation work, asset retirement obligations and environmental guarantees and indemnifications.
Legal Matters—Seagen is involved in various legal proceedings, including patent, intellectual property, and product liability matters of a nature considered normal to its business. The contingencies arising from legal matters are not significant to our consolidated financial statements.
Tax Matters—In the ordinary course of business, Seagen incurs liabilities for income taxes. Income taxes are exceptions to both the recognition and fair value measurement principles associated with the accounting for business combinations. Reserves for income tax contingencies continue to be measured under the benefit recognition model previously used by Seagen (see Note 1Q). Net liabilities for income taxes as of the acquisition date were $6.1 billion, including $56 million for uncertain tax positions. The net tax liability includes $7.5 billion for the tax impact of fair value adjustments, partially offset by $1.4 billion for deferred tax assets on which Seagen had recognized a valuation allowance.
Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Specifically, the goodwill recorded as part of the acquisition of Seagen includes the following:
the expected specific synergies and other benefits that we believe will result from combining the operations of Seagen with the operations of Pfizer;
any intangible assets that do not qualify for separate recognition, as well as future, as yet unidentified projects and products; and
the value of the going-concern element of Seagen’s existing businesses (the higher rate of return on the assembled collection of net assets versus if Pfizer had acquired all of the net assets separately).
Goodwill is not amortized and is not deductible for tax purposes. All of the goodwill related to the acquisition of Seagen is related to our Biopharma segment (see Note 10).
Actual and Pro Forma Impact of Acquisition—The following table presents information for Seagen’s operations that are included in Pfizer’s consolidated statements of income beginning from the acquisition date, December 14, 2023, through Pfizer’s year-end in 2023:
(MILLIONS)
December 31,
2023
Revenues$120
Net loss attributable to Pfizer Inc. common shareholders(a)
(746)
(a)Includes restructuring, integration and acquisition-related costs ($614 million pre-tax) and purchase accounting charges related to (i) the preliminary fair value adjustment for acquisition-date inventory estimated to have been sold ($109 million pre-tax); (ii) amortization expense related to the preliminary fair value of identifiable intangible assets acquired from Seagen ($25 million pre-tax); as well as (iii) depreciation expense related to the preliminary fair value adjustment of fixed assets acquired from Seagen ($2 million pre-tax).
The following table provides unaudited U.S. GAAP supplemental pro forma information as if the acquisition of Seagen had occurred on January 1, 2022:
Unaudited Supplemental Pro Forma Consolidated Results
Year Ended December 31,
(MILLIONS, EXCEPT PER SHARE DATA)20232022
Revenues$60,632 $102,127 
Net income/(loss) attributable to Pfizer Inc. common shareholders(1,474)27,938 
Diluted earnings/(loss) per share attributable to Pfizer Inc. common shareholders(0.26)4.87 
The unaudited supplemental pro forma consolidated results do not purport to reflect what the combined company’s results of operations would have been had the acquisition occurred on January 1, 2022, nor do they project the future results of operations of the combined company or reflect the expected realization of any cost savings associated with the acquisition. The actual results of operations of the combined company may differ significantly from the pro forma adjustments reflected here due to many factors.
The unaudited supplemental pro forma financial information includes various assumptions, including those related to the preliminary purchase price allocation of the assets acquired and the liabilities assumed from Seagen. The historical U.S. GAAP financial information of Pfizer and Seagen was adjusted, primarily for the following pre-tax adjustments:
Additional amortization expense (approximately $503 million in 2023 and $526 million in 2022) related to the preliminary estimate of the fair value of identifiable intangible assets acquired.

Pfizer Inc.2023 Form 10-K65


Notes to Consolidated Financial Statements
Pfizer Inc. and Subsidiary Companies
Additional expense related to the preliminary estimate of the fair value adjustment to acquisition-date inventory estimated to have been sold (approximately $796 million in 2023 and $887 million in 2022).
Additional interest expense (approximately $984 million in 2023 and $2.0 billion in 2022) related to the estimated debt issued by Pfizer and the commercial paper borrowings to partially finance the acquisition.
Elimination of interest income (approximately $1.2 billion in 2023 and $267 million in 2022) related to the debt issuance proceeds that were invested prior to the acquisition date and associated with money market funds under the assumption that a portion of these funds would have been liquidated to partially fund the acquisition.
Adjustment to move Seagen royalty income received from collaboration partners (approximately $203 million in 2023 and $165 million in 2022) from total revenues to other (income)/deductions, which is consistent with Pfizer’s presentation in 2023.
The above adjustments were then adjusted for the applicable tax impact using an estimated weighted-average statutory tax rate applied to the applicable pro forma adjustments.
The acquisition of Seagen had no impact on Pfizer’s weighted-average shares as no shares were issued.
GBT––On October 5, 2022, we acquired GBT, a biopharmaceutical company dedicated to the discovery, development and delivery of life-changing treatments for underserved patient communities, starting with sickle cell disease, for $68.50 per share in cash. The total fair value of the consideration transferred was $5.7 billion ($5.2 billion, net of cash acquired). In addition, $136 million in payments to GBT employees for the fair value of previously unvested long-term incentive awards was recognized as post-closing compensation expense and recorded in Restructuring charges and certain acquisition-related costs (see Note 3).
The final allocation of the consideration transferred to the assets acquired and the liabilities assumed was completed in 2023. In connection with this business combination, we recorded: (i) $4.4 billion in Identifiable intangible assets, consisting of $3.0 billion of IPR&D and $1.4 billion of developed technology rights with a useful life of six years, (ii) $1.1 billion of Goodwill, (iii) $644 million of inventories to be sold over approximately three years, (iv) $516 million of net deferred tax liabilities and (v) $331 million of assumed long-term debt that was paid in full in the fourth quarter of 2022.
Biohaven––On October 3, 2022, we acquired Biohaven, the maker of Nurtec ODT/Vydura (rimegepant), an innovative therapy approved for both acute treatment of migraine and prevention of episodic migraine in adults. The transaction included the acquisition of Biohaven’s CGRP programs, including rimegepant, zavegepant and a portfolio of five pre-clinical CGRP assets. Under the terms of the agreement, we acquired all outstanding common shares of Biohaven not already owned by us for $148.50 per share, in cash, for payments of approximately $11.5 billion, plus repayment of third-party debt of $863 million and redemption of Biohaven’s redeemable preferred stock for $495 million. Effective immediately prior to the closing of the acquisition, Biohaven completed the spin-off of Biohaven Ltd. (NYSE: BHVN), distributing Biohaven Ltd.’s shares to Biohaven shareholders. Biohaven Ltd. became a new publicly traded company that retained Biohaven’s non-CGRP development stage pipeline compounds. Pfizer, a Biohaven shareholder, received a pro rata portion of Biohaven Ltd.’s shares in the distribution and owns approximately 1.3% of Biohaven Ltd. as of December 31, 2023.
This acquisition follows on the November 2021 collaboration for the commercialization of rimegepant and zavegepant outside the U.S., in connection with which Pfizer acquired 2.6% of Biohaven’s common stock (see Note 2E). Biohaven Ltd. also has the right to receive tiered royalties from Pfizer on any annual net sales of rimegepant and zavegepant in the U.S. in excess of $5.25 billion. This contingent consideration was determined to have no fair value as of the acquisition date. Pfizer also acquired Biohaven’s commitments for payment of high single digit to mid-teen percentage tiered royalties on world-wide net sales excluding China and low to high single digit royalties on net sales in China of rimegepant and zavegepant as well as certain regulatory approval and commercial milestone payments associated with rimegepant and zavegepant of up to $1.1 billion under pre-existing third-party license and other agreements. These milestone amounts have been reduced by $608 million since the acquisition due to payments made and renegotiation of certain of the applicable agreements.
The total fair value of the consideration transferred was $11.8 billion, which includes the fair value of Pfizer’s previous investment in Biohaven on the acquisition date of approximately $300 million. The final allocation of the consideration transferred to the assets acquired and the liabilities assumed was completed in 2023. In connection with this business combination, we recorded: (i) $12.1 billion in Identifiable intangible assets, consisting of $11.6 billion of developed technology rights with a useful life of 11 years and $450 million of IPR&D, (ii) $823 million of Goodwill, (iii) $813 million of inventories to be sold over approximately two years, (iv) $398 million of trade accounts receivable, (v) $1.4 billion of assumed long-term debt that was paid in full in the fourth quarter of 2022, (vi) $544 million of net deferred tax liabilities and (vii) $526 million of Other current liabilities.
Arena––On March 11, 2022, we acquired Arena, a clinical stage company with development-stage therapeutic candidates in gastroenterology, dermatology and cardiology, for $100 per share in cash. The total fair value of the consideration transferred was $6.6 billion ($6.2 billion, net of cash acquired). In addition, $138 million in payments to Arena employees for the fair value of previously unvested long-term incentive awards was recognized as post-closing compensation expense and recorded in Restructuring charges and certain acquisition-related costs (see Note 3).
The final allocation of the consideration transferred to the assets acquired and the liabilities assumed was completed in 2023. In connection with this business combination, we recorded: (i) $5.5 billion in Identifiable intangible assets, consisting of $5.0 billion of IPR&Dand $460 million of indefinite-lived licensing agreements and other, (ii) $1.0 billionof Goodwill and (iii) $490 million of net deferred tax liabilities.
ReViral––On June 9, 2022, we acquired ReViral, a privately held, clinical-stage biopharmaceutical company focused on discovering, developing and commercializing novel antiviral therapeutics that target respiratory syncytial virus, for a total consideration of up to $536 million, including upfront payments of $436 million upon closing (including a base payment of $425 million plus working capital adjustments) and an additional $100 million contingent upon a future development milestone for a secondary pipeline asset. It was subsequently determined the applicable milestone was not achieved.
We accounted for the transaction as an asset acquisition since the lead asset, sisunatovir, represented substantially all of the fair value of the gross assets acquired. At the acquisition date, we recorded a $426 million charge representing an acquired IPR&D asset with no alternative

Pfizer Inc.2023 Form 10-K66


Notes to Consolidated Financial Statements
Pfizer Inc. and Subsidiary Companies
use in Acquired in-process research and development expenses, which is presented as a cash outflow from operating activities. Other assets acquired and liabilities assumed were not significant.
Trillium––On November 17, 2021, we acquired all of the issued and outstanding common stock not already owned by Pfizer of Trillium, a clinical stage immuno-oncology company developing therapies targeting cancer immune evasion pathways and specific cell targeting approaches, for $18.50 per share in cash, for total consideration of $2.0 billion, net of cash acquired. As a result, Trillium became our wholly owned subsidiary. We previously held a 2% ownership investment in Trillium. Trillium’s lead program, TTI-622, is an investigational fusion protein that is designed to block the inhibitory activity of CD47, a molecule that is overexpressed by a wide variety of tumors.
We accounted for the transaction as an asset acquisition since the lead asset, TTI-622, represented substantially all of the fair value of the gross assets acquired, which exclude cash acquired. At the acquisition date, we recorded a $2.1 billion charge representing an acquired IPR&D asset with no alternative future use in Acquired in-process research and development expenses, of which the $2.0 billion net cash consideration is presented as a cash outflow from operating activities. In connection with this acquisition, we recorded $256 million of assets acquired primarily consisting of cash and investments. Liabilities assumed were approximately $81 million.
Pro forma information for the aforementioned acquisitions (except for Seagen) has not been presented because these acquisitions were not material to our consolidated financial statements.
B. Divestitures
Divestiture of Early-Stage Rare Disease Gene Therapy Portfolio––On September 19, 2023, we completed an agreement with Alexion, under which Alexion purchased and licensed the assets of our early-stage rare disease gene therapy portfolio. This agreement is consistent with our previously announced strategy to pivot from viral capsid-based gene therapy approaches to harnessing new platform technologies that we believe can have a transformative impact on patients, such as mRNA or in vivo gene editing. Under the terms of the agreement, Alexion will pay us total consideration of up to $1 billion, consisting of an upfront payment of $300 million which was paid at closing and future contingent milestone payments, plus tiered royalties based on annual net sales of the assets. In connection with the closing of the transaction, Pfizer recognized a $222 million pre-tax gain in Other (income)/deductions––net (see Note 4).
Discontinued Operations
Meridian––On December 31, 2021, we completed the sale of our Meridian subsidiary for approximately $51 million in cash and recognized a loss of approximately $167 million, net of tax, in Discontinued operations––net of tax. In connection with the sale, Pfizer and the purchaser of Meridian entered into various agreements to provide a framework for our relationship after the sale, including interim TSAs and an MSA. Services under the TSAs are completed as of December 31, 2023. The MSA is for a term of three years post sale with a two year extension period. Amounts recorded under the interim TSAs and MSA in 2023 and 2022 were not material to our operations. No amounts were recorded under these arrangements in 2021.
Upjohn Separation and Combination with Mylan––In connection with the 2020 spin-off and the combination of the Upjohn Business with Mylan to form Viatris, Pfizer and Viatris entered into various agreements, including a separation and distribution agreement, interim operating models, including agency arrangements, MSAs, TSAs, a tax matters agreement, and an employee matters agreement, among others. The interim agency operating model arrangements primarily include billings, collections and remittance of rebates that we are performing on a transitional basis on behalf of Viatris. Under the MSAs, Pfizer or Viatris, as the case may be, manufactures, labels and packages products for the other party. The terms of the MSAs range in initial duration from four to seven years post-separation. Services under the TSAs were largely completed as of December 31, 2023. Amounts recorded under the above agreements in 2023, 2022 and 2021 were not material to our operations. Net amounts due to Viatris under the above agreements were $33 million as of December 31, 2023 and $94 million as of December 31, 2022. The cash flows associated with the above agreements are included in Net cash provided by operating activities from continuing operations, except fora $277 million payment to Viatris made in 2021 pursuant to terms of the separation agreement, which is reported in Other financing activities, net.

C. Equity-Method Investments
Haleon/Consumer Healthcare JV––On July 18, 2022, GSK completed a demerger of the Consumer Healthcare JV which became Haleon, an independent, publicly traded company listed on the London Stock Exchange that holds the joint historical consumer healthcare business of GSK and Pfizer following the demerger. We continue to own 32% of Haleon as of December 31, 2023.
The carrying value of our investment in Haleon as of December 31, 2023 and December 31, 2022 was $11.5 billion and $10.8 billion, respectively, and is reported in Equity-method investments. The fair value of our investment in Haleon as of December 31, 2023, based on quoted market prices of Haleon stock, was $12.1 billion. Haleon/the Consumer Healthcare JV is a foreign investee whose reporting currency is the U.K. pound, and therefore we translate its financial statements into U.S. dollars and recognize the impact of foreign currency translation adjustments in the carrying value of our investment and in other comprehensive income. The increase in the value of our investment from December 31, 2022 to December 31, 2023 is primarily due to our share of Haleon’s earnings of $489 million as well as $280 million in pre-tax foreign currency translation adjustments (see Note 6), partially offset by $153 million in dividends. We record our share of earnings from Haleon/the Consumer Healthcare JV on a quarterly basis on a one-quarter lag in Other (income)/deductions––net. Our total share of Haleon’s earnings generated in the fourth quarter of 2022 and the first nine months of 2023, which we recorded in our operating results in 2023, was $489 million. Our total share of Haleon/the Consumer Healthcare JV’s earnings generated in the fourth quarter of 2021 and the first nine months of 2022, which we recorded in our operating results in 2022, was $536 million. Our total share of the JV’s earnings generated in the fourth quarter of 2020 and the first nine months of 2021, which we recorded in our operating results in 2021, was $495 million. As part of the initial accounting for our investment in the Consumer Healthcare JV in 2019, we determined that the difference between the initial fair value of our investment less our underlying equity in the carrying value of the net assets of the JV resulted in an initial excess basis difference of $4.8 billion. We allocated the difference primarily to inventory, definite-lived intangible assets, indefinite-lived intangible assets, related deferred tax liabilities, and equity-method goodwill. We recognize amortization of these basis differences in Other (income)/deductions––net. Amortization of basis differences on inventory and related deferred tax liabilities was completely recognized by the second quarter of 2020. Basis differences on definite-lived intangible assets and related deferred tax liabilities are being amortized over the lives of the underlying assets, which range from 8 to 20 years. In 2022, our equity-method income included in Other (income)/ deductions––net also included charges of $100 million, primarily for adjustments to our equity-method basis differences related to the separation of Haleon/the Consumer Healthcare JV from GSK. The total amortization and adjustment of basis differences resulting from the excess of the initial fair value of our investment over the underlying equity in the carrying value of the net assets of Haleon/the Consumer Healthcare JV was not material to our results of operations in 2023 and 2021. See Note 4.

In connection with GSK’s previously announced planned demerger of at least 80% of GSK’s 68% equity interest in the Consumer Healthcare JV, in March 2022 the Consumer Healthcare JV completed its offering of a total aggregate principal amount of $8.75 billion in U.S. dollar-denominated senior notes of various maturities, €2.35 billion in euro-denominated senior notes of various maturities and £700 million in U.K. pound-denominated senior notes of various maturities (collectively, the “notes”). The notes were guaranteed by GSK generally up to and excluding the date of the demerger (the “Guarantee Assumption Date”). We agreed to indemnify GSK for 32% (representing our pro rata equity interest in the Consumer Healthcare JV) of any amount payable by GSK pursuant to its guarantee of the notes. Our indemnity was provided solely for the benefit of GSK. Neither we nor any of our subsidiaries were an issuer or guarantor of any of the notes.
Following its issuance of the notes in March 2022, which fell in our international second quarter of 2022, the Consumer Healthcare JV loaned to us and GSK the net proceeds received from the notes on a pro rata equity ownership basis, for which we received a loan of £2.9 billion ($3.7 billion as of the end of our second quarter of 2022), at an interest rate of 1.365% per annum payable semi-annually in arrears. In conjunction with the demerger, we received £3.5 billion ($4.2 billion) in dividends from the JV in July 2022, of which $4.0 billion related to a one-time pre-separation dividend, which decreased the carrying value of our investment and are included in Net cash provided by/(used in) investing activities. Simultaneous with the receipt of the dividends, we repaid the £2.9 billion loan from the JV. GSK similarly received pro rata dividends and simultaneously repaid its pro rata loan from the JV. In conjunction with these transactions, our indemnification of GSK’s guarantee discussed above was terminated.
Investment in ViiV––In 2009, we and GSK created ViiV, which is focused on research, development and commercialization of human immunodeficiency virus (HIV) medicines. We own approximately 11.7% of ViiV, and prior to 2016 we accounted for our investment under the equity method due to the significant influence that we have over the operations of ViiV through our board representation and minority veto rights. We suspended application of the equity method to our investment in ViiV in 2016 when the carrying value of our investment was reduced to zero due to the recognition of cumulative equity-method losses and dividends, and therefore we no longer record our proportionate share of ViiV’s net income (loss) in our results of operations. Since 2016, we have recognized dividends from ViiV as income in Other (income)/deductions––net when earned, including dividends of $265 million in 2023, $314 million in 2022 and $166 million in 2021 (see Note 4).
Summarized financial information for our equity-method investee, ViiV, as of December 31, 2023 and 2022 and for the years ending December 31, 2023, 2022, and 2021 is as follows:

D. Licensing Arrangement
Agreement with Valneva––In June 2022, we entered into an Equity Subscription Agreement, under which we invested €90.5 million ($95 million) in Valneva to further support our arrangement to co-develop and commercialize Lyme disease vaccine candidate, VLA15, which we originally entered into with Valneva in 2020. In addition, we updated the terms of our existing co-development and commercialization agreement for VLA15. Valneva will now fund 40% of the remaining shared development costs, and we will pay Valneva tiered royalties ranging from 14% to 22%, compared to royalties starting at 19% in the initial agreement. In addition, the royalties will be complemented by up to $100 million in milestones payable to Valneva based on cumulative sales. Other early commercialization milestones are unchanged. As of December 31, 2023, we held a 6.9% equity stake of Valneva.
E. Collaborative Arrangements
We enter into collaborative arrangements with respect to in-line medicines, as well as medicines in development that require completion of research and regulatory approval. Collaborative arrangements are contractual agreements with third parties that involve a joint operating activity, typically a research and/or commercialization effort, where both we and our partner are active participants in the activity and are exposed to the significant risks and rewards of the activity. Our rights and obligations under our collaborative arrangements vary. For example, we have agreements to co-promote pharmaceutical products discovered by us or other companies, and we have agreements where we partner to co-develop and/or participate together in commercializing, marketing, promoting, manufacturing and/or distributing a drug product or vaccine.
Collaboration with Biohaven––In November 2021, we entered into a collaboration and license agreement and related sublicense agreement with Biohaven and certain of its subsidiaries to commercialize rimegepant and zavegepant for the treatment and prevention of migraines outside of the U.S., subject to regulatory approval. Under the terms of the agreement, Biohaven would lead R&D globally and we would have the exclusive right to commercialization globally, outside of the U.S. Upon the closing of the transaction on January 4, 2022, we paid Biohaven $500 million, including an upfront payment of $150 million and an equity investment of $350 million. We recognized $263 million for the upfront payment and premium paid on our equity investment in Acquired in-process research and development expenses. In October 2022, we acquired all outstanding common shares of Biohaven not already owned by us for $148.50 per share, in cash, for payments of approximately $11.5 billion. See Note 2A. This acquisition represented a settlement of the pre-existing relationship, and we determined that no gain or loss was required to be recognized.
Collaborations with BioNTech––On December 30, 2021, we entered into a research, development and commercialization agreement to develop a potential first mRNA-based vaccine for the prevention of shingles (herpes zoster virus) based on BioNTech’s proprietary mRNA technology and our antigen technology. Under the terms of the agreement, we agreed to pay BioNTech $225 million, including an upfront cash payment of $75 million and an equity investment of $150 million. BioNTech is eligible to receive future regulatory and sales milestone payments of up to $200 million. In return, BioNTech agreed to pay us $25 million for our proprietary antigen technology. The net upfront payment to BioNTech was recorded to Acquired in-process research and development expenses in our fourth quarter of 2021. We and BioNTech share development costs. We will have commercialization rights to the potential vaccine worldwide, excluding Germany, Turkey and certain developing countries where BioNTech will have commercialization rights. We and BioNTech will share gross profits from commercialization of any product. As of December 31, 2023, we held an equity stake of 2.7% of BioNTech.
On April 9, 2020, we signed a global agreement with BioNTech to co-develop a mRNA-based coronavirus vaccine program aimed at preventing COVID-19 infection, which resulted in the development of Comirnaty. On January 29, 2021, we and BioNTech signed an amended version of the April 2020 agreement. Under the January 2021 agreement, BioNTech paid us their 50 percent share of prior development costs in a lump sum payment during the first quarter of 2021. Further R&D costs are being shared equally. We have commercialization rights to the vaccine worldwide, excluding Germany and Turkey where BioNTech markets and distributes the vaccine under the agreement with us, and excluding China, Hong Kong, Macau and Taiwan, which are subject to a separate collaboration between BioNTech and Shanghai Fosun Pharmaceutical (Group) Co., Ltd. We recognize revenues and cost of sales on a gross basis in markets where we are commercializing the vaccine and we record our share of gross profits related to sales of the vaccine by BioNTech in Germany and Turkey in Alliance revenues.
Collaboration with Beam––On December 24, 2021, we entered into a multi-year research collaboration with Beam to utilize Beam’s in vivo base editing programs, which use mRNA and lipid nanoparticles, for three targets for rare genetic diseases of the liver, muscle and central nervous system. Under the terms of the agreement, Beam conducts all research activities through development candidate selection for three undisclosed targets, which are not included in Beam’s existing programs, and we may opt in to obtain exclusive licenses to each development candidate. Beam has a right to opt in, at the end of phase 1/2 studies, upon the payment by Beam of an option exercise fee, to a global co-development and co-commercialization agreement with respect to one program licensed under the collaboration pursuant to which we and Beam would share net profits as well as development and commercialization costs in a 65%/35% ratio (Pfizer/Beam). Upon entering into the agreement, we recorded $300 million in Acquired in-process research and development expenses in the fourth quarter of 2021 for an upfront payment due to Beam, and if we exercise our opt in to licenses for all three targets, Beam will be eligible for up to an additional $1.05 billion in development, regulatory and commercial milestone payments for a potential total deal consideration of up to $1.35 billion. Beam is also eligible to receive royalties on global net sales for each licensed program.

Collaboration with Arvinas––On July 21, 2021, we entered into a global collaboration with Arvinas to develop and commercialize ARV-471, an investigational oral PROTAC® (PROteolysis TArgeting Chimera) estrogen receptor protein degrader. The estrogen receptor is a well-known disease driver in most breast cancers. In connection with the agreement, we made an upfront cash payment of $650 million to Arvinas and we made a $350 million equity investment in the common stock of Arvinas. We recognized $706 million for the upfront payment and a premium paid on our equity investment in Acquired in-process research and development expenses in our third quarter of 2021. Arvinas is also eligible to receive up to $400 million in approval milestones and up to $1 billion in commercial milestones. The companies equally share worldwide development costs, commercialization expenses and profits. As of December 31, 2023, we held a 5.1% equity stake of Arvinas.

(a)Represents sales to our partners of products manufactured by us.
(b)Substantially all relates to amounts earned from our partners under co-promotion agreements. The decrease in 2023 was primarily driven by a decline in Alliance revenues from Comirnaty, partially offset by an increase in Alliance revenues from Eliquis. The increase in 2022 was primarily driven by increases in Alliance revenues from Eliquis, Comirnaty and Bavencio.
(c)Primarily relates to amounts paid to collaboration partners for their share of net sales or profits earned in collaboration arrangements where we are the principal in the transaction, and cost of sales for inventory purchased from our partners. The decreases in 2023 and in 2022 primarily relate to Comirnaty.
(d)Represents net reimbursements to our partners for selling, informational and administrative expenses incurred.
(e)Represents net reimbursements from our partners for research and development expenses incurred.
(f)Primarily relates to upfront payments to our partners as well as premiums paid on our equity investments in the common stock of our partners.
(g)Primarily relates to royalties from our collaboration partners.
The amounts outlined in the above table do not include transactions with third parties other than our collaboration partners, or other costs for the products under the collaborative arrangements.
F. Research and Development Arrangement
Research and Development Funding Arrangement with Blackstone––In April 2023, we entered into an arrangement with Blackstone under which we will receive up to a total of $550 million in 2023 through 2026 to co-fund our quarterly development costs for specified treatments. As there is substantive transfer of risk to the financial partner, the development funding is recognized by us as an obligation to perform contractual services. We are recognizing the funding as a reduction of Research and development expenses using an attribution model over the period of the related expenses. The reduction to Research and development expenses in 2023 was $175 million. If successful, upon regulatory approval in the U.S. or certain major markets in the EU for the indications based on the applicable clinical trials, Blackstone will be eligible to receive approval-based fixed milestone payments of up to $468 million contingent upon the successful results of the clinical trials. Fixed milestone payments due upon approval will be recorded as intangible assets and amortized to Amortization of intangible assets over the shorter of the term of the agreement or estimated commercial life of the product. Following potential regulatory approval, Blackstone will be eligible to receive a combination of fixed milestone payments of up to $550 million in total based on achievement of certain levels of cumulative applicable net sales, as well as royalties based on a mid-to-high single digit percentage of the applicable net sales. Fixed sales-based milestone payments will be recorded as intangible assets and amortized to Amortization of intangible assets over the shorter of the term of the agreement or estimated commercial life of the product, and royalties on net sales will be recorded as Cost of sales when incurred.
Note 3.Restructuring Charges and Other Costs Associated with Acquisitions and Cost-Reduction/Productivity Initiatives
A. Restructuring Programs
Transforming to a More Focused Company Program––In 2019, we announced that we would be incurring costs associated with our Transforming to a More Focused Company Program, a multi-year effort to ensure our cost base aligned appropriately with our operating structure following Pfizer’s transformation into a more focused, innovative science-based global biopharmaceutical business. This program included activities to (i) restructure our corporate enabling functions to appropriately support our operating structure; (ii) transform our commercial go-to-market model; and (iii) optimize our manufacturing network and R&D operations. The costs to restructure our corporate enabling functions, and to optimize our R&D operations and reduce cycle times, as well as to further prioritize our internal R&D portfolio, primarily included severance and implementation costs. The costs to optimize our manufacturing network largely included severance, implementation costs, product transfer costs, site exit costs, and accelerated depreciation. From the start of this program in the fourth quarter of 2019 through December 31, 2023, we incurred costs of $4.0 billion, of which $1.5 billion ($1.0 billion of restructuring charges) was associated with our Biopharma segment and have substantially completed this program.

Pfizer Inc. and Subsidiary Companies
Realigning our Cost Base Program––In the fourth quarter of 2023, we announced that we launched a multi-year, enterprise-wide cost realignment program that aims to realign our costs with our longer-term revenue expectations. We expect costs associated with this multi-year effort to continue through 2024 and to total approximately $3.0 billion, primarily representing cash expenditures for severance and implementation costs, of which $1.1 billion is associated with our Biopharma segment.
In 2023, we incurred costs under this program of $1.7 billion, of which $674 million (including $665 million of restructuring charges) is associated with our Biopharma segment.

(a)Capitalized interest totaled $160 million in 2023, $124 million in 2022 and $108 million in 2021.
(b)The decrease in net interest expense in 2023 reflects higher interest expense driven by our $31 billion aggregate principal amount of senior unsecured notes issued in May 2023 as part of the financing for our acquisition of Seagen, which was more than offset by higher interest income on the investment of the net proceeds from the debt issuance.
(c)2023 net gains primarily include, among other things, a realized gain of $1.7 billion related to our investment in Telavant Holdings, Inc. and unrealized gains of $297 million related to our investment in Cerevel Therapeutics Holdings, Inc (Cerevel), partially offset by unrealized losses of $292 million related to our investment in BioNTech. 2022 net losses included, among other things, unrealized losses of $986 million related to investments in BioNTech, Allogene Therapeutics, Inc. and Arvinas. 2021 net gains included, among other things, unrealized gains of $1.6 billion related to investments in BioNTech and Cerevel.
(d)2021 included, among other things, $188 million of net collaboration income from BioNTech related to Comirnaty.
(e)2023 primarily includes certain product liability and other legal expenses related to products discontinued and/or divested by Pfizer and legal obligations related to pre-acquisition matters. 2022 primarily included certain product liability and other legal expenses related to products discontinued and/or divested by Pfizer. 2021 primarily included certain product liability expenses related to products discontinued and/or divested by Pfizer, and to a lesser extent, legal obligations related to pre-acquisition matters.
(f)2023 primarily represents intangible asset impairment charges of $3.0 billion, of which $2.9 billion is associated with our Biopharma segment ($2.8 billion recorded in the fourth quarter), including: $1.4 billion for etrasimod (Velsipity) IPR&D, based on a change in development plans for additional indications and overall revenue expectations, $964 million for Prevnar 13 developed technology rights ($834 million for pediatric and $130 million for adult), due to updated commercial forecasts mainly reflecting a transition to higher serotype coverage, and $486 million for various other IPR&D assets and developed technology rights, due to updated commercial forecasts mainly reflecting competitive pressures and/or prioritization decisions. 2023 also includes $128 million associated with Other business activities, related to IPR&D and developed technology rights for acquired software assets and reflects unfavorable pivotal trial results and updated commercial forecasts. 2022 represented intangible asset impairment charges associated with our Biopharma segment of: $200 million for an IPR&D asset for the unapproved indication of symptomatic dilated cardiomyopathy due to a mutation of the gene encoding the lamin A/C protein that resulted from the Phase 3 trial reaching futility at a pre-planned interim analysis and $171 million for developed technology rights due to updated commercial forecasts mainly reflecting competitive pressures. 2022 also included intangible asset impairment charges of $50 million associated with PC1, related to finite-lived licensing agreements and reflected updated contract manufacturing forecasts reflecting changes to market dynamics.
(g)See Note 2C.
(h)2023 includes, among other things, (i) dividend income of $265 million from our investment in ViiV and $211 million from our investment in Nimbus resulting from Takeda’s acquisition of Nimbus’s oral, selective allosteric tyrosine kinase 2 (TYK2) inhibitor program subsidiary and (ii) a $222 million gain on the divestiture of our early-stage rare disease gene therapy portfolio to Alexion. 2022 included, among other things, (i) dividend income of $314 million from our investment in ViiV, (ii) income net of costs associated with TSAs of $142 million and (iii) charges of $77 million, reflecting the change in the fair value of contingent consideration. 2021 included, among other things, (i) income net of costs associated with TSAs of $288 million, (ii) dividend income of $166 million from our investment in ViiV and (iii) charges of $142 million, reflecting the change in the fair value of contingent consideration.

(b)Reflects intangible assets written down to fair value in 2023. Fair value was determined using the income approach, specifically the multi-period excess earnings method, also known as the discounted cash flow method. We started with a forecast of all the expected net cash flows for the asset and then applied an asset-specific discount rate to arrive at a net present value amount. Some of the more significant estimates and assumptions inherent in this approach include: the amount and timing of the projected net cash flows, which includes the expected impact of competitive, legal and/or regulatory forces on the product; the discount rate, which seeks to reflect the various risks inherent in the projected cash flows; and the tax rate, which seeks to incorporate the geographic diversity of the projected cash flows.

(a)2023 v. 2022––The domestic loss in 2023 versus domestic income in 2022 and the decrease in international income in 2023 was primarily attributable to lower revenues, higher intangible asset impairment charges, and increases in Restructuring charges and certain acquisition-related costs, Amortization of intangible assets, and Selling, informational and administrative expenses, partially offset by a decrease in Cost of sales and net gains on equity securities in 2023 versus net losses on equity securities in 2022.
(b)2022 v. 2021––The decrease in domestic income is primarily related to net losses on equity securities in 2022 versus net gains on equity securities in 2021, lower net periodic benefit credits and higher restructuring charges and certain acquisition-related costs, partially offset by Paxlovid income and lower acquired IPR&D expenses. The increase in international income is primarily related to Paxlovid and Comirnaty income partially offset by lower net periodic benefit credits.

The changes in Provision/(benefit) for taxes on income impacting the effective tax rate year-over-year are summarized below:
2023 v. 2022
The tax benefit of $1.1 billion for 2023 compared to the tax provision of $3.3 billion for 2022 was primarily a result of changes in the jurisdictional mix of earnings and the resolution of uncertain tax positions in various markets. The 2023 pre-tax income included a greater percentage of expenses taxed at higher rates as compared to the 2022 pre-tax income, resulting in a 2023 tax benefit compared to the 2022 tax provision. These expenses included amortization expense, acquisition-related costs, restructuring charges and intangible asset impairment charges. The tax benefit for 2023 and the tax provision for 2022 included tax benefits related to global income tax resolutions in multiple tax jurisdictions spanning multiple tax years. The tax provision for 2022 also included the closing of U.S. IRS audits covering five tax years.
2022 v. 2021
The higher effective tax rate in 2022 was mainly the result of:
the non-recurrence of certain initiatives executed in 2021 associated with our investment in the Consumer Healthcare JV with GSK based on estimates and assumptions that we believe to be reasonable,
partially offset by:
tax benefits in 2022 related to global income tax resolutions in multiple tax jurisdictions spanning multiple tax years that included the closing of U.S. IRS audits covering five tax years.
In all years, federal, state and international net tax liabilities assumed or established as part of a business acquisition are not included in Provision/(benefit) for taxes on income (see Note 2A).
We elected, with the filing of our 2018 U.S. Federal Consolidated Income Tax Return, to pay our initial estimated $15 billion repatriation tax liability on accumulated post-1986 foreign earnings over eight years through 2026. The fifth annual installment of this liability was paid by its April 18, 2023 due date. The sixth annual installment is due April 15, 2024 and is reported in current Income taxes payable as of December 31, 2023. The remaining liability is reported in noncurrent Other taxes payable. Our obligations may vary as a result of changes in our uncertain tax positions and/or availability of attributes such as foreign tax and other credit carryforwards.

Effective tax rate for income from continuing operations(105.4)%9.6 %7.6 %
*The higher rate percentages for the 2023 reconciling items are significantly impacted by the lower domestic and international Income from continuing operations before provision/(benefit) for taxes on income (see Note 5A).
(a)For taxation of non-U.S. operations, this rate impact reflects the income tax rates and relative earnings in the locations where we do business outside the U.S., together with the U.S. tax cost on our international operations, changes in uncertain tax positions not included in the reconciling item called “Tax settlements and resolution of certain tax positions,” as well as changes in valuation allowances. Specifically: (i) the jurisdictional location of earnings is a significant component of our effective tax rate each year, and the rate impact of this component is influenced by the specific location of non-U.S. earnings and the level of such earnings as compared to our total earnings; (ii) the U.S. tax implications of our foreign operations is a significant component of our effective tax rate each year and generally offsets some of the reduction to our effective tax rate each year resulting from the jurisdictional location of earnings; (iii) the impact of certain tax initiatives; and (iv) the impact of changes in uncertain tax positions not included in the reconciling item called “Tax settlements and resolution of certain tax positions” is a component of our effective tax rate each year that can result in either an increase or decrease to our effective tax rate. The jurisdictional mix of earnings, which includes the impact of the location of earnings as well as the U.S. tax cost on our international operations, can vary as a result of operating fluctuations in the normal course of business and as a result of the extent and location of other income and expense items, such as restructuring charges, asset impairments and gains and losses on strategic business decisions. See also Note 5Afor the components of pre-tax income and Provision/(benefit) for taxes on income, which is based on the location of the taxing authorities, and for information about settlements and other items impacting Provision/(benefit) for taxes on income.
(b)In all years, the reduction in our effective tax rate is a result of the jurisdictional location of earnings and is largely due to lower tax rates in certain jurisdictions, as well as manufacturing and other incentives for our subsidiaries in Singapore and, to a lesser extent, in Puerto Rico. We benefit from Puerto Rican tax incentives pursuant to a grant that expires during 2053. Under such grant, we are partially exempt from income, property and municipal taxes. In Singapore, we benefit from incentive tax rates effective through 2048 on income from manufacturing and other operations.
(c)See Note 5A.
(d)The higher rate benefit from the Foreign-Derived Intangible Income deduction in 2022 is mainly the result of the TCJA requirement to capitalize R&D costs for tax years beginning after December 31, 2021.
(e)Includes the impact of U.S. state and local taxes and changes in the state valuation allowances including those related to the acquisition of Seagen.
(f)Includes changes in interest related to our uncertain tax positions not included in the reconciling item called “Tax settlements and resolution of certain tax positions”.
(g)All other, net is primarily due to routine business operations.

*The deferred tax assets and liabilities associated with global intangible low-taxed income are included in the relevant categories. See Note 1Q.
(a)The increase in net deferred tax assets in 2023 is primarily related to temporary differences associated with the timing of cash tax payments made and accruals recorded in the ordinary course of business.
(b)The increase in deferred tax assets in 2023 is primarily related to temporary differences associated with the non-cash revenue reversal for Paxlovid recorded in the fourth quarter of 2023. See Note 17C.
(c)The decrease in net deferred tax assets in 2023 is primarily due to the acquisition of inventories related to Seagen, partially offset by the temporary differences associated with the non-cash charges for inventory write-offs for Paxlovid and Comirnaty.
(d)The increase in net deferred tax liabilities in 2023 is primarily due to the acquisition of intangible assets related to Seagen, partially offset by the amortization of intangible assets and certain impairment charges.
(e)The decrease in net deferred tax assets in 2023 is primarily due to changes in pension and postretirement benefit obligations, as well as the performance of plan assets reported in the period. See Note 11.
(f)The increase in deferred tax assets in 2023 is primarily related to the acquisition of capitalized R&D costs related to Seagen and the TCJA requirement to capitalize R&D costs for tax years beginning after December 31, 2021.
(g)The increase in deferred tax assets in 2023 is primarily due to the acquisition of net operating loss carryforwards and credit carryforwards related to Seagen. See Note 2A.
(h)The amounts in 2023 and 2022 are reduced for unrecognized tax benefits of $1.3 billion and $1.2 billion, respectively, where we have net operating loss carryforwards, similar tax losses, and/or tax credit carryforwards that are available, under the tax law of the applicable jurisdiction, to settle any additional income taxes that would result from the disallowance of a tax position.
(i)The increase in net deferred tax liabilities in 2023 is primarily due to the impact of foreign currency translation adjustments related to our equity-method investment in Haleon/the Consumer Healthcare JV. See Note 2C.
(j)In 2023, Noncurrent deferred tax assets and other noncurrent tax assets ($1.8 billion), and Noncurrent deferred tax liabilities ($0.6 billion). In 2022, Noncurrent deferred tax assets and other noncurrent tax assets ($4.8 billion), and Noncurrent deferred tax liabilities ($1.0 billion).
(k)Excludes indefinite- and definite-lived deferred tax assets for certain non-U.S. tax losses and interest carryforwards and U.S. state general business credits, totaling $11.1 billion, given that management has determined based on applicable accounting rules that it is remote that these tax attributes will be utilized.
We have carryforwards, primarily related to net operating and capital losses, general business credits, foreign tax credits and charitable contributions, which are available to reduce future U.S. federal and/or state, as well as international, income taxes payable with either an indefinite life or expiring at various times from 2024 to 2043. Certain of our U.S. net operating losses and general business credits are subject to limitations under IRC Section 382.
As of December 31, 2023, we have not made a U.S. tax provision on $49.0 billion of unremitted earnings of our international subsidiaries. As these earnings are intended to be indefinitely reinvested overseas, the determination of a hypothetical unrecognized deferred tax liability as of December 31, 2023 is not practicable. The amount of indefinitely reinvested earnings is based on estimates and assumptions and subject to management evaluation, and is subject to change in the normal course of business based on operational cash flow, completion of local statutory financial statements and the finalization of tax returns and audits, among other things. Accordingly, we regularly update our earnings and profits analysis for such events.
D. Tax Contingencies

Uncertain Tax Positions
As tax law is complex and often subject to varied interpretations, it is uncertain whether some of our tax positions will be sustained upon audit. As of December 31, 2023, we had $3.1 billion and as of December 31, 2022, we had $2.9 billion in net unrecognized tax benefits, excluding associated interest.
Tax assets for uncertain tax positions primarily represent our estimate of the potential tax benefits in one tax jurisdiction that could result from the payment of income taxes in another tax jurisdiction. These potential benefits generally result from cooperative efforts among taxing authorities, as required by tax treaties to minimize double taxation, commonly referred to as the competent authority process. The recoverability of these assets, which we believe to be more likely than not, is dependent upon the actual payment of taxes in one tax jurisdiction and, in some cases, the successful petition for recovery in another tax jurisdiction. As of December 31, 2023, we had $1.7 billion in assets associated with uncertain tax positions. These amounts were included in Noncurrent deferred tax assets and other noncurrent tax assets ($1.6 billion) and Other taxes payable ($45 million). As of December 31, 2022, we had $1.5 billion in assets associated with uncertain tax positions. These amounts were included in Noncurrent deferred tax assets and other noncurrent tax assets ($1.5 billion) and Other taxes payable ($45 million).
Substantially all of these unrecognized tax benefits, if recognized, would impact our effective income tax rate.
The reconciliation of the beginning and ending amounts of gross unrecognized tax benefits follows:

(c)Primarily related to cash payments and reductions of tax attributes.
(d)Primarily related to decreases as a result of a lapse of applicable statutes of limitations.
(e)In 2023, included in Income taxes payable ($94 million), Other current assets ($1 million), Noncurrent deferred tax assets and other noncurrent tax assets ($1.3 billion), Noncurrent deferred tax liabilities ($4 million) and Other taxes payable ($3.4 billion). In 2022, included in Income taxes payable ($40 million), Other current assets ($3 million), Noncurrent deferred tax assets and other noncurrent tax assets ($1.2 billion), Noncurrent deferred tax liabilities ($5 million) and Other taxes payable ($3.2 billion).
Interest related to our unrecognized tax benefits is recorded in accordance with the laws of each jurisdiction and is recorded primarily in Provision/(benefit) for taxes on income. In 2023, we recorded a net increase in interest of $64 million. In 2022, we recorded a net decrease in interest of $17 million. In 2021, we recorded a net increase in interest of $108 million. Gross accrued interest totaled $605 million as of December 31, 2023 (reflecting a decrease of $11 million as a result of cash payments) and gross accrued interest totaled $552 million as of December 31, 2022 (reflecting a decrease of $31 million as a result of cash payments). In 2023 and 2022, these amounts were substantially all included in Other taxes payable. Accrued penalties are not significant. See also Note 5A.
Status of Tax Matters and Potential Impact on Accruals for Uncertain Tax Positions
The U.S. is one of our major tax jurisdictions, and we are regularly audited by the IRS. With respect to Pfizer, tax years 2016-2018 are under audit. Tax years 2019-2023 are open but not under audit. All other tax years are closed. In addition to the open audit years in the U.S., we have open audit years and certain related audits, appeals and investigations in certain major international tax jurisdictions such as Canada (2017-2023), Europe (2012-2023, primarily in Ireland, the U.K., France, Italy, Spain and Germany), Asia Pacific (2013-2023, primarily in Australia, China, Japan and Singapore) and Latin America (1998-2023, primarily in Brazil).
Any settlements or statutes of limitations expirations could result in a significant decrease in our uncertain tax positions. We estimate that it is reasonably possible that within the next 12 months, our gross unrecognized tax benefits, exclusive of interest, could decrease by as much as $100 million, as a result of settlements with taxing authorities or the expiration of the statutes of limitations. Our assessments are based on estimates and assumptions that have been deemed reasonable by management, but our estimates of unrecognized tax benefits and potential tax benefits may not be representative of actual outcomes, and variation from such estimates could materially affect our financial statements in the period of settlement or when the statutes of limitations expire, as we treat these events as discrete items in the period of resolution. Finalizing audits with the relevant taxing authorities can include formal administrative and legal proceedings, and, as a result, it is difficult to estimate the timing and range of possible changes related to our uncertain tax positions, and such changes could be significant.

Financial Assets and Liabilities Not Measured at Fair Value on a Recurring Basis––The carrying value of Long-term debt, excluding the current portion was $62 billion as of December 31, 2023 and $33 billion as of December 31, 2022. The estimated fair value of such debt, using a market approach and Level 2 inputs, was $61 billion as of December 31, 2023 and $30 billion as of December 31, 2022.
The differences between the estimated fair values and carrying values of held-to-maturity debt securities, private equity securities, long-term receivables and short-term borrowings not measured at fair value on a recurring basis were not significant as of December 31, 2023 and 2022. The fair value measurements of our held-to-maturity debt securities and short-term borrowings are based on Level 2 inputs. The fair value measurements of our long-term receivables and private equity securities are based on Level 3 inputs.

E. Derivative Financial Instruments and Hedging Activities
Foreign Exchange Risk––A significant portion of our revenues, earnings and net investments in foreign affiliates is exposed to changes in foreign exchange rates. Where foreign exchange risk is not offset by other exposures, we manage our foreign exchange risk principally through the use of derivative financial instruments and foreign currency debt. These financial instruments serve to mitigate the impact on net income as a result of remeasurement into another currency, or against the impact of translation into U.S. dollars of certain foreign exchange-denominated transactions.
The derivative financial instruments primarily hedge or offset exposures in the euro, U.K. pound, Japanese yen, Canadian dollar, and Chinese renminbi, and include a portion of our forecasted foreign exchange-denominated intercompany inventory sales hedged up to two years. We may seek to protect against possible declines in the reported net investments of our foreign business entities.
Changes in fair value are reported in earnings or in Other comprehensive income/(loss), depending on the nature and purpose of the financial instrument (hedge or offset relationship). For certain foreign exchange contracts, we exclude an amount from the assessment of hedge effectiveness and recognize the excluded amount through an amortization approach in earnings. The hedge relationships are as follows:
Generally, we recognize the gains and losses on foreign exchange contracts that are designated as fair value hedges in earnings upon the recognition of the change in fair value of the hedged item. We also recognize the offsetting foreign exchange impact attributable to the hedged item in earnings.
Generally, we record in Other comprehensive income/(loss) gains or losses on foreign exchange contracts that are designated as cash flow hedges and reclassify those amounts into earnings in the same period or periods during which the hedged transaction affects earnings.
We record in Other comprehensive income/(loss)––Foreign currency translation adjustments, net the foreign exchange gains and losses related to foreign exchange-denominated debt and foreign exchange contracts designated as a hedge of our net investments in foreign subsidiaries and reclassify those amounts into earnings upon the sale or substantial liquidation of our net investments.
For foreign exchange contracts not designated as hedging instruments, we recognize the gains and losses immediately into earnings along with the earnings impact of the items they generally offset. These contracts take the opposite currency position of that reflected on the balance sheet to counterbalance the effect of any currency movement.
Interest Rate Risk––Our interest-bearing investments and borrowings are subject to interest rate risk. Depending on market conditions, we may change the profile of our outstanding debt or investments by entering into derivative financial instruments like interest rate swaps, either to hedge or offset the exposure to changes in the fair value of hedged items with fixed interest rates, or to convert variable rate debt or investments to fixed rates. The derivative financial instruments primarily hedge U.S. dollar fixed-rate debt.
We recognize the change in fair value on interest rate contracts that are designated as fair value hedges in earnings, as well as the offsetting earnings impact of the hedged risk attributable to the hedged item.

F. Credit Risk
On an ongoing basis, we monitor and review the credit risk of our customers, financial institutions and exposures in our 2017investment portfolio.
With respect to our trade accounts receivable, we monitor the creditworthiness of our customers to which we grant credit in the normal course of business. In general, there is no requirement for collateral from customers. For additional information on our trade accounts receivable and allowance for credit losses, see Note 1G. A significant portion of our trade accounts receivable balances are due from wholesalers and governments. For additional information on our trade accounts receivables with significant customers, see Note 17C.

Notes to Consolidated Financial Report.Statements

Pfizer Inc. and Subsidiary Companies
With respect to our investments, we monitor concentrations of credit risk associated with government, government agency, and corporate issuers of securities. Investments are placed in instruments that are investment grade and are primarily short in duration. Exposure limits are established to limit a concentration with any single credit counterparty. As of December 31, 2023, the largest investment exposures in our portfolio consisted primarily of U.S. government money market funds, as well as sovereign debt instruments issued by the U.S.
With respect to our derivative financial instrument agreements with financial institutions, we do not expect to incur a significant loss from failure of any counterparty. Derivative financial instruments are executed under International Swaps and Derivatives Association master agreements with credit-support annexes that contain zero threshold provisions requiring collateral to be exchanged daily depending on levels of exposure. As a result, there are no significant concentrations of credit risk with any individual financial institution. As of December 31, 2023, the aggregate fair value of these derivative financial instruments that are in a net payable position was $768 million, for which we have posted collateral of $771 million with a corresponding amount reported in Short-term investments. As of December 31, 2023, the aggregate fair value of our derivative financial instruments that are in a net receivable position was $225 million, for which we have received collateral of $221 million with a corresponding amount reported in Short-term borrowings, including current portion of long-term debt.

$10,189 $8,981 
Noncurrent inventories not included above(b)
$4,568 $5,827 
(a)The increase from December 31, 2022 of $1.2 billion reflects an increase of approximately $1.0 billion representing acquired Seagen inventory, inclusive of the fair value step-up (see Note 2A), and increases for certain products due to new product launches, supply recovery and changes in net market demand. These increases were offset to a large extent by $1.0 billion in inventory write-offs for Paxlovid and Comirnaty.
(b)Included in Other noncurrent assets. The decrease from December 31, 2022 of $1.3 billion is primarily driven by inventory write-offs for Paxlovid of $4.2 billion and, to a lesser extent, inventory write-offs for Comirnaty of $0.7 billion, offset to a large extent by an increase of approximately $3.1 billion representing acquired Seagen inventory, inclusive of the fair value step-up (see Note 2A). The charges and corresponding inventory write-offs were based on our analysis of Paxlovid and Comirnaty inventory levels as of December 31, 2023 in relation to our commercial outlook for both products. Based on current estimates and assumptions, there are no recoverability issues for these amounts.
B. Other Current Liabilities
Other current liabilities includes, among other things, amounts payable to BioNTech for the gross profit split for Comirnaty, which totaled $2.0 billion as of December 31, 2023 and $5.2 billion as of December 31, 2022.
C. Supplier Finance Program Obligation
We maintain voluntary supply chain finance agreements with several participating financial institutions. Under these agreements, participating suppliers may voluntarily elect to sell their accounts receivable with Pfizer to these financial institutions. Our suppliers negotiate their financing agreements directly with the respective financial institutions and we are not a party to these agreements. We have no economic interest in our suppliers’ decision to participate and we pay the financial institutions the stated amount of confirmed invoices on the original maturity dates, which is generally within 90 to 120 days of the invoice date. The agreements with the financial institutions do not require Pfizer to provide assets pledged as security or other forms of guarantees for the supplier finance program. All outstanding amounts related to suppliers participating in such financing arrangements are recorded within trade payables in our consolidated balance sheet. As of December 31, 2023 and December 31, 2022, respectively, $791 million and $849 million of our trade payables to suppliers who participate in these financing arrangements were outstanding.

(a)The increase in the gross carrying amount primarily includes, among other things: (i) $7.5 billion for the acquisition of Seagen (see Note 2A); (ii) the transfer of IPR&D to developed technology rights of $3.6 billion for etrasimod (Velsipity), $2.1 billion for Padcev, $1.1 billion for Braftovi/Mektovi, and $450 million as a result of the approval in the U.S. for Zavzpret nasal spray; and (iii) $495 million of capitalized milestones as a result of the approval in the U.S. for Zavzpret nasal spray, partially offset by (iv) impairments of $964 million for Prevnar 13 (see Note 4).
(b)The increase in the gross carrying amount primarily reflects $450 million for the acquisition of Seagen (see Note 2A).
(c)The increase in the gross carrying amount mainly reflects $20.8 billion for the acquisition of Seagen (see Note 2A), partially offset by the transfer from IPR&D to developed technology rights as mentioned in note (a) above, and impairments of $1.4 billion for etrasimod (Velsipity).
(d)The increase is primarily due to $28.8 billion for the acquisition of Seagen (see Note 2A) and the $495 million of capitalized milestones described in note (a) above, partially offset by amortization expense of $4.7 billion and impairments of $3.0 billion (see Note 4).
Developed Technology Rights––Developed technology rights represent the cost for developed technology acquired from third parties and can include the right to develop, use, market, sell and/or offer for sale the product, compounds and intellectual property that we have acquired with respect to products, compounds and/or processes that have been completed. We possess a well-diversified portfolio of hundreds of developed technology rights across therapeutic categories, representing our commercialized products. The significant components of developed technology rights are the following: Nurtec ODT/Vydura, Adcetris, Xtandi, etrasimod (Velsipity), Padcev, Braftovi/Mektovi, Prevnar 13 family and Oxbryta. Also included in this category are the post-approval milestone payments made under our alliance agreements for certain prescription pharmaceutical products.
Brands––Brands represent the cost for tradenames and know-how, as the products themselves do not receive patent protection. Indefinite-lived brands include Medrol and Depo-Medrol, while finite-lived brands include Zavedos and Depo-Provera.
IPR&D––IPR&D assets represent the acquisition date fair value (less impairments) of R&D assets acquired through business combinations that have not yet received regulatory approval in a major market which could include both new investigational products and additional indications for in-line products. The significant components of IPR&D are SGN-B6A, Disitamab vedotin, GBT601, Tukysa, Padcev and talazoparib. IPR&D assets are required to be classified as indefinite-lived assets until the successful completion or the abandonment of the associated R&D effort. Accordingly, during the development period after the date of acquisition, these assets are not amortized until approval is obtained in a major market, typically either the U.S. or the EU, or in a series of other countries, subject to certain specified conditions and management judgment. At that time, we will determine the useful life of the asset, reclassify it out of IPR&D and begin amortization. If the associated R&D effort is abandoned, the related IPR&D assets will be written-off, and we will record an impairment charge. IPR&D assets are high-risk assets, given the uncertain nature of R&D. Accordingly, IPR&D assets may become impaired and/or be written-off in the future.
Licensing Agreements––Licensing agreements for developed technology and for technology in development primarily relate to out-licensing arrangements acquired from third parties, including the Array, Arena and Seagen acquisitions. These assets represent the cost for the license, where we acquired the right to future royalties and/or milestones upon development or commercialization by the licensing partners. A

Notes to Consolidated Financial Statements
Pfizer Inc. and Subsidiary Companies
significant component of the licensing arrangements are for out-licensing arrangements with a number of partners. Accordingly, during the development period after the date of acquisition, each of these assets is classified as indefinite-lived intangible assets and will not be amortized until approval is obtained in a major market. At that time we will determine the useful life of the asset, reclassify the respective licensing arrangement asset to finite-lived intangible asset and begin amortization. If the development effort is abandoned, the related licensing asset will be written-off, and we will record an impairment charge.
Amortization––The weighted-average life for each of our total finite-lived intangible assets is approximately 11 years, and for the largest component, developed technology rights, is approximately 11 years.

Note 11. Pension and Postretirement Benefit Plans and Defined Contribution Plans
The majority of our employees worldwide are eligible for retirement benefits provided through defined benefit pension plans, defined contribution plans or both. In the U.S., we sponsor both IRC-qualified and supplemental (non-qualified) defined benefit plans and defined contribution plans. A qualified plan meets the requirements of certain sections of the IRC, and, generally, contributions to qualified plans are tax deductible. A qualified plan typically provides benefits to a broad group of employees with restrictions on discriminating in favor of highly compensated employees with regard to coverage, benefits and contributions. A supplemental (non-qualified) plan provides additional benefits to certain employees. In addition, we provide medical insurance benefits to certain retirees and their eligible dependents through our postretirement plans.

(a)The rate of compensation increase is not used to determine the net periodic benefit cost and benefit obligation for the U.S. pension plans as these plans are frozen.
All of the assumptions are reviewed at least annually. We revise these assumptions based on an annual evaluation of long-term trends as well as market conditions that may have an impact on the cost of providing retirement benefits.
The weighted-average discount rate for our U.S. defined benefit plans is set with reference to the prevailing market rate of a portfolio of high-quality fixed income investments, rated AA/Aa or better that reflect the rates at which the pension benefits could be effectively settled. For our international plans, the discount rates are set by benchmarking against investment grade corporate bonds rated AA/Aa or better, including, when there is sufficient data, a yield curve approach. These rate determinations are made consistent with local requirements. Overall, the yield curves used to measure the benefit obligations at year-end 2023 resulted in broadly unchanged discount rates for the U.S. pension and postretirement plans and higher discount rates for the international pension plans as compared to the prior year.
The following provides the healthcare cost trend rate assumptions for our U.S. postretirement benefit plans:

(c)As a result of a group annuity contract entered into between Pfizer and a third-party insurance company in July 2022, the third party insurance company assumed future benefit obligations and responsibility for the annuity payments of certain retirees in the Pfizer Consolidated Pension Plan. Benefit obligations of $586 million and plan assets of $588 million were associated with this contract. In February 2024, regulatory approval was received for this contract.
(d)Our main U.S. qualified plan, U.S. postretirement plan and many of our larger funded international plans were overfunded as of December 31, 2023.

Pfizer Inc. and Subsidiary Companies
The following methods and assumptions were used to estimate the fair value of our pension and postretirement plans’ assets:
Cash and cash equivalents: Level 1 investments may include cash, cash equivalents and foreign currency valued using exchange rates. Level 2 investments may include short-term investment funds which are commingled funds priced at a stable NAV by the administrator of the funds.
Equity securities: Level 1 investments may include individual securities that are valued at the closing price or last trade reported on the major market on which they are traded. Level 1 and Level 2 investments may include commingled funds that have a readily determinable fair value based on quoted prices on an exchange or a published NAV derived from the quoted prices in active markets of the underlying securities. Level 3 investments may include individual securities that are unlisted, delisted, suspended, or illiquid and are typically valued using their last available price.
Fixed income securities: Level 1 investments may include individual securities that are valued at the closing price or last trade reported on the major market on which they are traded. Level 2 investments may include commingled funds that have a readily determinable fair value based on observable prices of the underlying securities. Level 2 investments may include corporate bonds, government and government agency obligations and other fixed income securities valued using bid evaluation pricing models or quoted prices of securities with similar characteristics. Level 3 investments may include securities that are valued using alternative pricing sources, such as investment managers or brokers, which use proprietary pricing models that incorporate unobservable inputs.
Other investments: Level 1 investments may include individual securities that are valued at the closing price or last trade reported on the major market on which they are traded. Level 2 investments may include insurance contracts which invest in interest bearing cash, U.S. government securities and corporate debt instruments. Level 3 investments may include securities or insurance contracts that are valued using alternative pricing sources, such as investment managers or brokers, which use proprietary pricing models that incorporate unobservable inputs.
Equity securities, Fixed income securities and Other investments may each be combined into commingled funds. Most commingled funds are valued to reflect the interest in the fund based on the reported year-end NAV. Partnership and Other investments are valued based on year-end reported NAV (or its equivalent), with adjustments as appropriate for lagged reporting of up to three months.
Certain investments are authorized to include derivatives, such as equity or bond futures, swaps, options and currency futures or forwards for managing risks and exposures.
Global plan assets are managed with the objective of generating returns that will enable the plans to meet their future obligations, while seeking to manage net periodic benefit costs and cash contributions over the long-term. We utilize long-term asset allocation ranges in the management of our plans’ invested assets. Our long-term return expectations are developed based on a diversified, global investment strategy that takes into account historical experience, as well as the impact of portfolio diversification, active portfolio management, and our view of current and future economic and financial market conditions. As market conditions and other factors change, we may adjust our targets accordingly and our asset allocations may vary from the target allocations.
E. Cash Flows
It is our practice to fund amounts for our qualified pension plans that are at least sufficient to meet the minimum requirements set forth in applicable employee benefit laws and local tax laws.
The following provides the expected future cash flow information related to our benefit plans:
  Pension PlansPostretirement Plans

The above table reflects the total U.S. and international plan benefits projected to be paid from the plans or from our general assets under the current actuarial assumptions used for the calculation of the benefit obligation.
F. Defined Contribution Plans
We have defined contribution plans in the U.S. and other countries. For the majority of the U.S. defined contribution plans, employees may contribute a portion of their salaries and bonuses to the plans, and we match, in cash, a portion of the employee contributions. We also offer a Retirement Savings Contribution which is an annual non-contributory employer contribution in the U.S. and Puerto Rico. We recorded charges related to the employer contributions to global defined contribution plans of $843 million in 2023, $770 million in 2022 and $732 million in 2021.
Note 12. Equity
A. Common Stock Purchases
We purchase our common stock through privately negotiated transactions or in the open market as circumstances and prices warrant. Purchased shares under a share-purchase plan, which is authorized by our BOD, are available for general corporate purposes. In December

Pfizer Inc.2023 Form 10-K90


Notes to Consolidated Financial Statements
Pfizer Inc. and Subsidiary Companies
2018, the BOD authorized a $10 billion share repurchase program to be utilized over time and share repurchases commenced thereunder in the first quarter of 2019.
In the first quarter of 2022, we purchased 39 million shares of our common stock at a cost of $2 billion under our publicly announced share-purchase plan. Our remaining share-purchase authorization was approximately $3.3 billion as of December 31, 2023.
B. Employee Stock Ownership Plans
We have one ESOP that holds common stock of the Company (Common ESOP). As of December 31, 2023, all shares of common stock held by the Common ESOP have been allocated to the Pfizer U.S. defined contribution plan participants. The compensation cost related to the Common ESOP was $20 million for 2023 and $19 million for each of 2022 and 2021.
Note 13. Share-Based Payments
Our compensation programs can include share-based payment awards with value that is determined by reference to the fair value of our shares and that provide for the grant of shares or options to acquire shares or similar arrangements. Our share-based awards are designed based on competitive survey data or industry peer groups used for compensation purposes, and are allocated between different long-term incentive awards, generally in the form of Total Shareholder Return Units (TSRUs), Restricted Stock Units (RSUs), Portfolio Performance Shares (PPSs), Performance Share Awards (PSAs), Breakthrough Performance Awards (BPAs) and stock options, as determined by the Compensation Committee of our BOD. No BPAs were granted in 2023 and no BPAs were outstanding as of December 31, 2023.
The 2019 Stock Plan (2019 Plan) provides for 400 million shares to be authorized for grants. The number of stock options, TSRUs, RSUs, or performance-based awards that may be granted to any one individual during any 36-month period is limited to 20 million shares. RSUs count as three shares, and PPSs, PSAs and BPAs count as three shares times the maximum potential payout, while TSRUs and stock options count as one share, toward the maximum shares available under the 2019 Plan. As of December 31, 2023, 248 million shares were available for award, including 68 million shares that we assumed from the remaining shares available from the stock plan of Seagen which can be issued to legacy employees of Seagen and newly hired employees after the date of acquisition once such shares are registered on Form S-8. Although not required to do so, we have used authorized and unissued shares and, to a lesser extent, treasury stock to satisfy our obligations under these programs.

A summary of the awards and valuation details:
Awarded toTermsValuationRecognition and Presentation
Total Shareholder Return Units (TSRUs)
Senior and other key management and select employees
Entitle the holder to receive shares of our common stock with a value equal to the difference between the defined settlement price and the grant price, plus the dividend equivalents accumulated during the five or seven-year term, if and to the extent the total value is positive.
Settlement price is the average closing price of our common stock during the 20 trading days ending on the fifth or seventh anniversary of the grant, as applicable; the grant price is the closing price of our common stock on the date of the grant.
Automatically settle on the fifth or seventh anniversary of the grant but vest on the third anniversary of the grant.
Retirement-eligible holders can convert their TSRUs, when vested, into Profit Units (PTUs) with a conversion ratio based on a calculation used to determine the shares at TSRU settlement. The PTUs are entitled to earn Dividend Equivalent Units (DEUs), and the PTUs and DEUs will be settled in our common stock on the TSRUs’ original settlement date and will be subject to the terms and conditions of the original grant including forfeiture provisions.

Note 15. Leases
We lease real estate, fleet, and equipment for use in our operations. Our leases generally have lease terms of 1 to 30 years, some of which include options to terminate or extend leases for up to 5 to 10 years or on a month-to-month basis. We include options that are reasonably certain to be exercised as part of the determination of lease terms. We may negotiate termination clauses in anticipation of any changes in market conditions, but generally these termination options have not been exercised. Residual value guarantees are generally not included within our operating leases with the exception of some fleet leases. In addition to base rent payments, the leases may require us to pay directly for taxes and other non-lease components, such as insurance, maintenance and other operating expenses, which may be dependent on usage or vary month-to-month. Variable lease payments amounted to $444 million in 2023, $536 million in 2022 and $381 million in 2021. We elected the practical expedient to not separate non-lease components from lease components in calculating the amounts of ROU assets and lease liabilities for all underlying asset classes.
We determine if an arrangement is a lease at inception of the contract and we perform the lease classification test as of the lease commencement date. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date

based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our estimated incremental borrowing rate based on the information available at commencement date in determining the present value of future payments.

Note 16. Contingencies and Certain Commitments
We and certain of our subsidiaries are subject to numerous contingencies arising in the ordinary course of business, including tax and legal contingencies, guarantees and indemnifications. The following outlines our legal contingencies, guarantees and indemnifications. For a discussion of our tax contingencies, see Note 5D.
A. Legal Proceedings
Our legal contingencies include, but are not limited to, the following:
Patent litigation, which typically involves challenges to the coverage and/or validity of patents on various products, processes or dosage forms. An adverse outcome could result in loss of patent protection for a product, a significant loss of revenues from a product or impairment of the value of associated assets. We are the plaintiff in the majority of these actions.

Pfizer Inc.2023 Form 10-K95


Notes to Consolidated Financial Statements
Pfizer Inc. and Subsidiary Companies
Product liability and other product-related litigation related to current or former products, which can include personal injury, consumer, off-label promotion, securities, antitrust and breach of contract claims, among others, and often involves highly complex issues relating to medical causation, label warnings and reliance on those warnings, scientific evidence and findings, actual, provable injury and other matters.
Commercial and other asserted or unasserted matters, which can include acquisition-, licensing-, intellectual property-, collaboration- or co-promotion-related and product-pricing claims and environmental claims and proceedings, and can involve complexities that will vary from matter to matter.
Government investigations, which often are related to the extensive regulation of pharmaceutical companies by national, state and local government agencies in the U.S. and in other jurisdictions.
Certain of these contingencies could result in increased expenses and/or losses, including damages, royalty payments, fines and/or civil penalties, which could be substantial, and/or criminal charges.
We believe that our claims and defenses in matters in which we are a defendant are substantial, but litigation is inherently unpredictable and excessive verdicts do occur. We do not believe that any of these matters will have a material adverse effect on our financial position. However, we could incur judgments, enter into settlements or revise our expectations regarding the outcome of matters, which could have a material adverse effect on our results of operations and/or our cash flows in the period in which the amounts are accrued or paid.
We have accrued for losses that are both probable and reasonably estimable. Substantially all of our contingencies are subject to significant uncertainties and, therefore, determining the likelihood of a loss and/or the measurement of any loss can be complex. Consequently, we are unable to estimate the range of reasonably possible loss in excess of amounts accrued. Our assessments, which result from a complex series of judgments about future events and uncertainties, are based on estimates and assumptions that have been deemed reasonable by management, but that may prove to be incomplete or inaccurate, and unanticipated events and circumstances may occur that might cause us to change those estimates and assumptions.
Amounts recorded for legal and environmental contingencies can result from a complex series of judgments about future events and uncertainties and can rely heavily on estimates and assumptions. For proceedings under environmental laws to which a governmental authority is a party, we have adopted a disclosure threshold of $1 million in potential or actual governmental monetary sanctions.
The principal pending matters to which we are a party are discussed below. In determining whether a pending matter is a principal matter, we consider both quantitative and qualitative factors to assess materiality, such as, among others, the amount of damages and the nature of other relief sought, if specified; our view of the merits of the claims and of the strength of our defenses; whether the action purports to be, or is, a class action and, if not certified, our view of the likelihood that a class will be certified by the court; the jurisdiction in which the proceeding is pending; whether related actions have been transferred to multidistrict litigation; any experience that we or, to our knowledge, other companies have had in similar proceedings; whether disclosure of the action would be important to a reader of our financial statements, including whether disclosure might change a reader’s judgment about our financial statements in light of all of the information that is available to the reader; the potential impact of the proceeding on our reputation; and the extent of public interest in the matter. In addition, with respect to patent matters in which we are the plaintiff, we consider, among other things, the financial significance of the product protected by the patent(s) at issue. Some of the matters discussed below include those which management believes that the likelihood of possible loss in excess of amounts accrued is remote.
A1. Legal Proceedings––Patent Litigation
We are involved in suits relating to our patents (or those of our collaboration/licensing partners to which we have licenses or co-promotion rights), including but not limited to, those discussed below. We face claims by generic drug manufacturers that patents covering our products (or those of our collaboration/licensing partners to which we have licenses or co-promotion rights and to which we may or may not be a party), processes or dosage forms are invalid and/or do not cover the product of the generic drug manufacturer. Also, counterclaims, as well as various 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. In addition to the challenges to the U.S. patents that are discussed below, patent rights to certain of our products or those of our collaboration/licensing partners are being challenged in various other jurisdictions. Some of our collaboration or licensing partners face challenges to the validity of their patent rights in non-U.S. jurisdictions. For example, in April 2022, the U.K. High Court issued a judgment finding invalid a BMS patent related to Eliquis due to expire in 2026. In May 2023, the Court of Appeal dismissed BMS’s appeal and in October 2023, the Supreme Court refused BMS’s permission to appeal. Additional challenges are pending in other jurisdictions. Also, in July 2022, CureVac AG (CureVac) brought a patent infringement action against BioNTech and certain of its subsidiaries in the German Regional Court alleging that Comirnaty infringes certain German utility model patents and certain expired and unexpired European patents. Additional challenges involving Comirnaty patents may be filed against us and/or BioNTech in other jurisdictions in the future. Adverse decisions in these matters could have a material adverse effect on our results of operations.We are also party to patent damages suits in various jurisdictions pursuant to which generic drug manufacturers, payors, governments or other parties are seeking damages from us for allegedly causing 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, as well as court proceedings relating to our intellectual property or the intellectual property rights of others, including challenges to such rights initiated by us. Also, if one of our patents (or one of our collaboration/licensing partner’s patents) is found to be invalid by such proceedings, generic or competitive products could be introduced into the market resulting in the erosion of sales of our existing products. For example, several of the patents in our pneumococcal vaccine portfolio have been challenged in inter partes review and post-grant review proceedings in the U.S. Patent and Trademark Office, as well as outside the U.S.The invalidation of any of the patents in our pneumococcal portfolio could potentially allow additional competitor vaccines, if approved, to enter the marketplace earlier than anticipated. In the event that any of the patents are found valid and infringed, a competitor’s vaccine, if approved, might be prohibited from entering the market or a competitor might be required to pay us a royalty.
We are also subject to patent litigation pursuant to which one or more third parties seek damages and/or injunctive relief to compensate for alleged infringement of its patents by our commercial or other activities. If one of our marketed products (or a product of our collaboration/

Pfizer Inc.2023 Form 10-K96


Notes to Consolidated Financial Statements
Pfizer Inc. and Subsidiary Companies
licensing partners to which we have licenses or co-promotion rights) is found to infringe valid patent rights of a third party, such third party may be awarded significant damages or royalty payments, or we may be prevented from further sales of that product. Such damages may be enhanced as much as three-fold if we or one of our subsidiaries is found to have willfully infringed valid patent rights of a third party.
Actions In Which We Are The Plaintiff
Xeljanz (tofacitinib)
Beginning in 2017, we brought patent-infringement actions against several generic manufacturers that filed separate abbreviated new drug applications (ANDAs) with the FDA seeking approval to market their generic versions of tofacitinib tablets in one or both of 5 mg and 10 mg dosage strengths, and in both immediate and extended release forms. To date, we have settled actions with several manufacturers on terms not material to us. The remaining actions continue in the U.S. District Court for the District of Delaware as described below.
In October 2021, we brought a separate patent-infringement action against Sinotherapeutics Inc. (Sinotherapeutics) asserting the infringement and validity of our patent covering extended release formulations of tofacitinib that was challenged by Sinotherapeutics in its ANDA seeking approval to market a generic version of tofacitinib 11 mg extended release tablets. In November 2022, we filed an additional patent-infringement action against Sinotherapeutics relating to its challenge of our extended release formulation and method of treatment patents in its ANDA seeking approval to market a generic version of tofacitinib 22 mg extended release tablets.
In June 2023, we brought a patent-infringement action against Aurobindo Pharma Limited and Aurobindo Pharma USA, Inc. (collectively Aurobindo) asserting the infringement and validity of our basic compound patent, in connection with Aurobindo’s ANDA seeking approval to market a generic version of tofacitinib 11 mg extended release tablets. In December 2023, we reached a settlement agreement with Aurobindo on terms not material to the Company.
Ibrance (palbociclib)
Beginning in January 2021, several generic companies notified us that they had filed ANDAs with the FDA seeking approval to market generic versions of Ibrance tablets. We have settled with one of these generic companies on terms not material to us, and have dismissed the patent infringement actions against all other generic companies except for the action against Synthon Pharmaceuticals Inc. and its affiliated entities (collectively, Synthon), in which we have asserted the infringement and validity of the composition of matter patent, expiring in 2027. In December 2023, we reached a settlement agreement with Synthon on terms not material to the Company.
Mektovi (binimetinib)
Beginning in August 2022, several generic companies notified us that they had filed ANDAs with the FDA seeking approval to market generic versions of Mektovi. The companies assert the invalidity and non-infringement of two method of use patents expiring in 2030, a method of use patent expiring in 2031, two method of use patents expiring in 2033, and a product by process patent expiring in 2033. Beginning in September 2022, we brought patent infringement actions against the generic filers in the U.S. District Court for the District of Delaware, asserting the validity and infringement of all six patents.
In August 2022 we received notice from Teva Pharmaceuticals, Inc. (Teva) that it had filed an ANDA seeking approval to market a generic version of Mektovi. Teva asserts the invalidity and non-infringement of two method of use patents expiring in 2033 and a product by process patent expiring in 2033. In June 2023, we brought a patent infringement action against Teva in the U.S. District Court for the District of Delaware, asserting the validity and infringement of the three patents.
Vyndaqel-Vyndamax(tafamidis/tafamidis meglumine)
Beginning in June 2023, several generic companies notified us that they had filed ANDAs with the FDA seeking approval to market generic versions of tafamidis capsules (61 mg) or tafamidis meglumine capsules (20 mg), challenging some or all of the patents listed in the FDA’s Orange Book for Vyndamax (tafamidis) and Vyndaqel (tafamidis meglumine). Scripps Research Institute (Scripps) owns the composition of matter patent and the method of treatment patents covering the products, and Pfizer is the exclusive licensee. Pfizer separately owns the crystalline form patent. Beginning in August 2023, we and Scripps brought patent infringement actions against the generic filers in the U.S. District Court for the District of Delaware, asserting the validity and infringement of the patents in suit. Pfizer is the sole plaintiff in actions that assert only the infringement and validity of the crystalline form patent.
Actions in Which We are the Defendant
Comirnaty
In March 2022, Alnylam Pharmaceuticals, Inc. (Alnylam) filed a complaint in the U.S. District Court for the District of Delaware against Pfizer and Pharmacia & Upjohn Company LLC, our wholly owned subsidiary, alleging that Comirnaty infringes a U.S. patent issued in February 2022, and seeking unspecified monetary damages. In July 2022, Alnylam filed a second complaint in the U.S. District Court for the District of Delaware against Pfizer, Pharmacia & Upjohn Company LLC, BioNTech and BioNTech Manufacturing GmbH, alleging that Comirnaty infringes a U.S. patent issued in July 2022, and seeking unspecified monetary damages. In May 2023, Alnylam filed a separate complaint in the U.S. District Court for the District of Delaware against Pfizer and Pharmacia & Upjohn Company LLC alleging that Comirnaty infringes four additional U.S. patents issued on various dates in 2023 and seeking unspecified monetary damages.
In August 2022, ModernaTX, Inc. (ModernaTX) and Moderna US, Inc. (Moderna) sued Pfizer, BioNTech, BioNTech Manufacturing GmbH and BioNTech US Inc. in the U.S. District Court for the District of Massachusetts, alleging that Comirnaty infringes three U.S. patents. In its complaint, Moderna stated that it is seeking damages for alleged infringement occurring after March 7, 2022.
In August 2022, ModernaTX filed a patent infringement action in Germany against Pfizer and certain subsidiary companies, as well as BioNTech and certain subsidiary companies, alleging that Comirnaty infringes two European patents. The German infringement action was stayed in December 2023 pending further action from the European Patent Office on the patents at issue. In September 2022, ModernaTX filed patent infringement actions in the U.K. and in the Netherlands against Pfizer and certain subsidiary companies, as well as BioNTech and certain subsidiary companies, on the same two European patents. In its complaints, ModernaTX stated that it is seeking damages for alleged infringement occurring after March 7, 2022. In the U.K., Pfizer and BioNTech brought an action against ModernaTX seeking to revoke these two European patents, which was consolidated with the September 2022 action filed by ModernaTX. In November 2023, one of the European patents was revoked by the European Patent Office. In December 2023, the other European patent was declared invalid by a court in the

Pfizer Inc. and Subsidiary Companies
Netherlands (the invalidity decision is limited to the Netherlands). ModernaTX has also filed additional patent infringement actions against Pfizer and BioNTech in certain other ex-U.S. jurisdictions.
In April 2023, Arbutus Biopharma Corporation (Arbutus) and Genevant Sciences GmbH (Genevant) filed a complaint in the U.S. District Court for the District of New Jersey against Pfizer and BioNTech alleging that Comirnaty and its manufacture infringe five U.S. patents, and seeking unspecified monetary damages.
Paxlovid
In June 2022, Enanta Pharmaceuticals, Inc. filed a complaint in the U.S. District Court for the District of Massachusetts against Pfizer alleging that the active ingredient in Paxlovid, nirmatrelvir, infringes a U.S. patent issued in June 2022, and seeking unspecified monetary damages.
Abrysvo
In August 2023, GlaxoSmithKline Biologics SA and GlaxoSmithKline LLC (collectively, GSK Group) filed a complaint in the U.S. District Court for the District of Delaware against Pfizer alleging that the active ingredient in Abrysvo infringes four U.S. patents. The complaint seeks unspecified monetary damages and a permanent injunction against sales of Abrysvo for use in adults over 60 years of age. In November 2023, GSK Group amended its complaint to assert infringement of two additional patents. In addition, we have challenged certain of GSK’s RSV vaccine patents in certain ex-U.S. jurisdictions, including the U.K., the Netherlands and Belgium, and GSK has asserted that Abrysvo infringes these patents.
Matters Involving Pfizer and its Collaboration/Licensing Partners
Comirnaty
In July 2022, Pfizer, BioNTech and BioNTech Manufacturing GmbH filed a declaratory judgment complaint against CureVac in the U.S. District Court for the District of Massachusetts seeking a judgment of non-infringement for three U.S. patents relating to Comirnaty. In May 2023, the case was transferred to the U.S. District Court for the Eastern District of Virginia. Also in May 2023, CureVac asserted that Comirnaty infringes the three patents that were the subject of our declaratory judgment complaint, and in May and July 2023, CureVac asserted that Comirnaty infringes a number of additional U.S. patents.
In the U.K., Pfizer and BioNTech have sued CureVac seeking a judgment of invalidity of several patents and CureVac has made certain infringement counterclaims.
A2. Legal Proceedings––Product Litigation
We are defendants in numerous cases, including but not limited to those discussed below, related to our pharmaceutical and other products. Plaintiffs in these cases seek damages and other relief on various grounds for alleged personal injury and economic loss.
Asbestos
Between 1967 and 1982, Warner-Lambert owned American Optical Corporation (American Optical), which manufactured and sold respiratory protective devices and asbestos safety clothing. In connection with the sale of American Optical in 1982, Warner-Lambert agreed to indemnify the purchaser for certain liabilities, including certain asbestos-related and other claims. Warner-Lambert was acquired by Pfizer in 2000 and is a wholly owned subsidiary of Pfizer. Warner-Lambert is actively engaged in the defense of, and will continue to explore various means of resolving, these claims.
Numerous lawsuits against American Optical, Pfizer and certain of its previously owned subsidiaries are pending in various federal and state courts seeking damages for alleged personal injury from exposure to products allegedly containing asbestos and other allegedly hazardous materials sold by Pfizer and certain of its previously owned subsidiaries.
There also are a small number of lawsuits pending in various federal and state courts seeking damages for alleged exposure to asbestos in facilities owned or formerly owned by Pfizer or its subsidiaries.
Effexor
Beginning in 2011, actions, including purported class actions, were filed in various federal courts against Wyeth and, in certain of the actions, affiliates of Wyeth and certain other defendants relating to Effexor XR, which is the extended-release formulation of Effexor. The plaintiffs in each of the class actions seek to represent a class consisting of all persons in the U.S. and its territories who directly purchased, indirectly purchased or reimbursed patients for the purchase of Effexor XR or generic Effexor XR from any of the defendants from June 14, 2008 until the time the defendants’ allegedly unlawful conduct ceased. The plaintiffs in all of the actions allege delay in the launch of generic Effexor XR in the U.S. and its territories, in violation of federal antitrust laws and, in certain of the actions, the antitrust, consumer protection and various other laws of certain states, as the result of Wyeth fraudulently obtaining and improperly listing certain patents for Effexor XR in the Orange Book, enforcing certain patents for Effexor XR and entering into a litigation settlement agreement with a generic drug manufacturer with respect to Effexor XR. Each of the plaintiffs seeks treble damages (for itself in the individual actions or on behalf of the putative class in the purported class actions) for alleged price overcharges for Effexor XR or generic Effexor XR in the U.S. and its territories since June 14, 2008. All of these actions have been consolidated in the U.S. District Court for the District of New Jersey.
In 2014, the District Court dismissed the direct purchaser plaintiffs’ claims based on the litigation settlement agreement, but declined to dismiss the other direct purchaser plaintiff claims. In 2015, the District Court entered partial final judgments as to all settlement agreement claims, including those asserted by direct purchasers and end-payor plaintiffs, which plaintiffs appealed to the U.S. Court of Appeals for the Third Circuit. In 2017, the U.S. Court of Appeals for the Third Circuit reversed the District Court’s decisions and remanded the claims to the District Court.
Lipitor
Beginning in 2011, purported class actions relating to Lipitor were filed in various federal courts against, among others, Pfizer, certain Pfizer affiliates, and, in most of the actions, Ranbaxy Laboratories Limited (Ranbaxy) and certain Ranbaxy affiliates. The plaintiffs in these various actions seek to represent nationwide, multi-state or statewide classes consisting of persons or entities who directly purchased, indirectly purchased or reimbursed patients for the purchase of Lipitor (or, in certain of the actions, generic Lipitor) from any of the defendants from March 2010 until the cessation of the defendants’ allegedly unlawful conduct (the Class Period). The plaintiffs allege delay in the launch of generic Lipitor, in violation of federal antitrust laws and/or state antitrust, consumer protection and various other laws, resulting from (i) the

Pfizer Inc.2023 Form 10-K98


Notes to Consolidated Financial Statements
Pfizer Inc. and Subsidiary Companies
2008 agreement pursuant to which Pfizer and Ranbaxy settled certain patent litigation involving Lipitor and Pfizer granted Ranbaxy a license to sell a generic version of Lipitor in various markets beginning on varying dates, and (ii) in certain of the actions, the procurement and/or enforcement of certain patents for Lipitor. Each of the actions seeks, among other things, treble damages on behalf of the putative class for alleged price overcharges for Lipitor (or, in certain of the actions, generic Lipitor) during the Class Period. In addition, individual actions have been filed against Pfizer, Ranbaxy and certain of their affiliates, among others, that assert claims and seek relief for the plaintiffs that are substantially similar to the claims asserted and the relief sought in the purported class actions described above. These various actions have been consolidated for pre-trial proceedings in a MDL in the U.S. DistrictCourt for the District of New Jersey.
In September 2013 and 2014, the District Court dismissed with prejudice the claims of the direct purchasers. In October and November 2014, the District Court dismissed with prejudice the claims of all other MDL plaintiffs. All plaintiffs appealed the District Court’s orders dismissing their claims with prejudice to the U.S. Court of Appeals for the Third Circuit. In addition, the direct purchaser class plaintiffs appealed the order denying their motion to amend the judgment and for leave to amend their complaint to the Court of Appeals. In 2017, the Court of Appeals reversed the District Court’s decisions and remanded the claims to the District Court.
Also, in 2013, the State of West Virginia filed an action in West Virginia state court against Pfizer and Ranbaxy, among others, that asserts claims and seeks relief on behalf of the State of West Virginia and residents of that state that are substantially similar to the claims asserted and the relief sought in the purported class actions described above.
EpiPen (Direct Purchaser)
In February 2020, a lawsuit was filed in the U.S. District Court for the District of Kansas against Pfizer, its current and former affiliates King and Meridian, and various Mylan entities, on behalf of a purported U.S. nationwide class of direct purchaser plaintiffs who purchased EpiPen devices directly from the defendants. Plaintiffs in this action generally allege that Pfizer and Mylan conspired to delay market entry of generic EpiPen through the settlement of patent litigation regarding EpiPen, and thereby delayed market entry of generic EpiPen in violation of federal antitrust law. Plaintiffs seek treble damages for alleged overcharges for EpiPen since 2011. In July 2021, the District Court granted defendants’ motion to dismiss the direct purchaser complaint, without prejudice. In September 2021, plaintiffs filed an amended complaint. In August 2022, the District Court granted Pfizer’s motion to dismiss the complaint, and plaintiffs appealed to the U.S. Court of Appeals for the Tenth Circuit. In October 2023, the parties reached an agreement to settle the litigation on terms not material to Pfizer. The settlement is subject to court approval.
Docetaxel
Personal Injury Actions
A number of lawsuits have been filed against Hospira and Pfizer in various federal and state courts alleging that plaintiffs who were treated with Docetaxel developed permanent hair loss. The significant majority of the cases also name other defendants, including the manufacturer of the branded product, Taxotere. Plaintiffs seek compensatory and punitive damages. Additional lawsuits have been filed in which plaintiffs allege they developed blocked tear ducts following their treatment with Docetaxel.
In 2016, the federal cases were transferred for coordinated pre-trial proceedings to a MDL in the U.S. District Court for the Eastern District of Louisiana. In 2022, the eye injury cases were transferred for coordinated pre-trial proceedings to a MDL in the U.S. District Court for the Eastern District of Louisiana.
Mississippi Attorney General Government Action
In 2018, the Attorney General of Mississippi filed a complaint in Mississippi state court against the manufacturer of the branded product and eight other manufacturers including Pfizer and Hospira, alleging, with respect to Pfizer and Hospira, a failure to warn about a risk of permanent hair loss in violation of the Mississippi Consumer Protection Act. The action seeks civil penalties and injunctive relief.
Zantac
A number of lawsuits have been filed against Pfizer in various federal and state courts alleging that plaintiffs developed various types of cancer, or face an increased risk of developing cancer, purportedly as a result of the ingestion of Zantac. The significant majority of these cases also name other defendants that have historically manufactured and/or sold Zantac. Pfizer has not sold Zantac since 2006, and only sold an OTC version of the product. In 2006, Pfizer sold the consumer business that included its Zantac OTC rights to Johnson & Johnson and transferred the assets and liabilities related to Zantac OTC to Johnson & Johnson in connection with the sale. Plaintiffs in these cases seek compensatory and punitive damages.
In February 2020, the federal actions were transferred for coordinated pre-trial proceedings to a MDL in the U.S. District Court for the Southern District of Florida (the Federal MDL Court). Plaintiffs in the MDL filed against Pfizer and many other defendants a master personal injury complaint, a consolidated consumer class action complaint alleging, among other things, claims under consumer protection statutes of all 50 states, and a medical monitoring complaint seeking to certify medical monitoring classes under the laws of 13 states. In December 2022, the Federal MDL Court granted defendants’ Daubert motions to exclude plaintiffs’ expert testimony and motion for summary judgment on general causation, which has resulted in the dismissal of all complaints in the litigation. Plaintiffs have appealed the Federal MDL Court’s rulings.
In addition, (i) Pfizer has received service of Canadian class action complaints naming Pfizer and other defendants, and seeking compensatory and punitive damages for personal injury and economic loss, allegedly arising from the defendants’ sale of Zantac in Canada; and (ii) the State of New Mexico and the Mayor and City Council of Baltimore separately filed civil actions against Pfizer and many other defendants in state courts, alleging various state statutory and common law claims in connection with the defendants’ alleged sale of Zantac in those jurisdictions. In April 2021, a Judicial Council Coordinated Proceeding was created in the Superior Court of California in Alameda County to coordinate personal injury actions against Pfizer and other defendants filed in California state court. Coordinated proceedings have also been created in other state courts. The large majority of the state court cases have been filed in the Superior Court of Delaware in New Castle County.
Many of these Zantac-related cases have been outstanding for a number of years and could take many more years to resolve. From time to time, Pfizer has explored and will continue to explore opportunistic settlements of these matters.

Pfizer Inc. and Subsidiary Companies
Chantix
Beginning in August 2021, a number of putative class actions have been filed against Pfizer in various U.S. federal courts following Pfizer’s voluntary recall of Chantix due to the presence of a nitrosamine, N-nitroso-varenicline. Plaintiffs assert that they suffered economic harm purportedly as a result of purchasing Chantix or generic varenicline medicines sold by Pfizer. Plaintiffs seek to represent nationwide and state-specific classes and seek various remedies, including damages and medical monitoring. In December 2022, the federal actions were transferred for coordinated pre-trial proceedings to a MDL in the U.S. District Court for the Southern District of New York. Similar putative class actions have been filed in Canada and Israel, where the product brand is Champix.
A3. Legal Proceedings––Commercial and Other Matters
Monsanto-Related Matters
In 1997, Monsanto Company (Former Monsanto) contributed certain chemical manufacturing operations and facilities to a newly formed corporation, Solutia Inc. (Solutia), and spun off the shares of Solutia. In 2000, Former Monsanto merged with Pharmacia & Upjohn Company to form Pharmacia. Pharmacia then transferred its agricultural operations to a newly created subsidiary, named Monsanto Company (New Monsanto), which it spun off in a two-stage process that was completed in 2002. Pharmacia was acquired by Pfizer in 2003 and is a wholly owned subsidiary of Pfizer.
In connection with its spin-off that was completed in 2002, New Monsanto assumed, and agreed to indemnify Pharmacia for, any liabilities related to Pharmacia’s former agricultural business. New Monsanto has defended and/or is defending Pharmacia in connection with various claims and litigation arising out of, or related to, the agricultural business, and has been indemnifying Pharmacia when liability has been imposed or settlement has been reached regarding such claims and litigation.
In connection with its spin-off in 1997, Solutia assumed, and agreed to indemnify Pharmacia for, liabilities related to Former Monsanto’s chemical businesses. As the result of its reorganization under Chapter 11 of the U.S. Bankruptcy Code, Solutia’s indemnification obligations relating to Former Monsanto’s chemical businesses are primarily limited to sites that Solutia has owned or operated. In addition, in connection with its spin-off that was completed in 2002, New Monsanto assumed, and agreed to indemnify Pharmacia for, any liabilities primarily related to Former Monsanto’s chemical businesses, including, but not limited to, any such liabilities that Solutia assumed. Solutia’s and New Monsanto’s assumption of, and agreement to indemnify Pharmacia for, these liabilities apply to pending actions and any future actions related to Former Monsanto’s chemical businesses in which Pharmacia is named as a defendant, including, without limitation, actions asserting environmental claims, including alleged exposure to polychlorinated biphenyls. Solutia and/or New Monsanto are defending Pharmacia in connection with various claims and litigation arising out of, or related to, Former Monsanto’s chemical businesses, and have been indemnifying Pharmacia when liability has been imposed or settlement has been reached regarding such claims and litigation.
Environmental Matters
In 2009, as part of our acquisition of Wyeth, we assumed responsibility for environmental remediation at the Wyeth Holdings LLC (formerly known as Wyeth Holdings Corporation and American Cyanamid Company) discontinued industrial chemical facility in Bound Brook, New Jersey. Since that time, we have executed or have become a party to a number of administrative settlement agreements, orders on consent, and/or judicial consent decrees, with the U.S. Environmental Protection Agency, the New Jersey Department of Environmental Protection and/or federal and state natural resource trustees to perform remedial design, removal and remedial actions, and related environmental remediation activities, and to resolve alleged damages to natural resources, at the Bound Brook facility. We have accrued for the currently estimated costs of these activities.
We are also party to a number of other proceedings brought under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended, and other state, local or foreign laws in which the primary relief sought is the cost of past and/or future remediation.
Contracts with Iraqi Ministry of Health
In 2017, a number of U.S. service members, civilians, and their families brought a complaint in the U.S. District Court for the District of Columbia against a number of pharmaceutical and medical devices companies, including Pfizer and certain of its subsidiaries, alleging that the defendants violated the U.S. Anti-Terrorism Act. The complaint alleges that the defendants provided funding for terrorist organizations through their sales practices pursuant to pharmaceutical and medical device contracts with the Iraqi Ministry of Health, and seeks monetary relief. In July 2020, the District Court granted defendants’ motions to dismiss and dismissed all of plaintiffs’ claims. In January 2022, the Court of Appeals reversed the District Court’s decision. In February 2022, the defendants filed for en banc review of the Court of Appeals’ decision. In February 2023, the Court of Appeals denied defendants’ en banc petitions.
Allergan Complaint for Indemnity
In 2019, Pfizer was named as a defendant in a complaint, along with King, filed by Allergan Finance LLC (Allergan) in the Supreme Court of the State of New York, asserting claims for indemnity related to Kadian, which was owned for a short period by King in 2008, prior to Pfizer's acquisition of King in 2010. This suit was voluntarily discontinued without prejudice in January 2021.
Viatris Securities Litigation
In October 2021, a putative class action was filed in the Court of Common Pleas of Allegheny County, Pennsylvania on behalf of former Mylan N.V. shareholders who received Viatris common stock in exchange for Mylan shares in connection with the spin-off of the Upjohn Business and its combination with Mylan (the Transactions). Viatris, Pfizer, and certain of each company’s current and former officers, directors and employees are named as defendants. An amended complaint was filed in January 2023, and alleges that the defendants violated certain provisions of the Securities Act of 1933 in connection with certain disclosures made in or omitted from the registration statement and related prospectus issued in connection with the Transactions, as well as related communications. Plaintiff seeks damages, costs and expenses and other equitable and injunctive relief. In November 2023, the parties reached an agreement to settle the litigation on terms not material to Pfizer. The settlement is subject to court approval.
Breach of Contract – Comirnaty
In 2023, Pfizer and BioNTech Manufacturing GmbH initiated separate formal proceedings against the Republic of Poland, the Republic of Romania and Hungary in Belgium’s Court of First Instance of Brussels. Pfizer and BioNTech are seeking an order from the Court holding those countries to their commitments for COVID-19 vaccine orders, which were placed as part of their contracts signed in 2021.

A4. Legal Proceedings––Government Investigations
We are subject to extensive regulation by government agencies in the U.S., other developed markets and multiple emerging markets in which we operate. Criminal charges, substantial fines and/or civil penalties, limitations on our ability to conduct business in applicable jurisdictions, corporate integrity or deferred prosecution agreements, as well as reputational harm and increased public interest in the matter could result from government investigations in the U.S. and other jurisdictions in which we do business. These matters often involve government requests for information on a voluntary basis or through subpoenas after which the government may seek additional information through follow-up requests or additional subpoenas. In addition, in a qui tam lawsuit in which the government declines to intervene, the relator may still pursue a suit for the recovery of civil damages and penalties on behalf of the government. Among the investigations by government agencies are the matters discussed below.
Greenstone Investigations
U.S. Department of Justice Antitrust Division Investigation
Since July 2017, the U.S. Department of Justice’s Antitrust Division has been investigating our former Greenstone generics business. We believe this is related to an ongoing broader antitrust investigation of the generic pharmaceutical industry. We have produced records relating to this investigation.
State Attorneys General and Multi-District Generics Antitrust Litigation
In April 2018, Greenstone received requests for information from the Antitrust Department of the Connecticut Office of the Attorney General. In May 2019, Attorneys General of more than 40 states plus the District of Columbia and Puerto Rico filed a complaint against a number of pharmaceutical companies, including Greenstone and Pfizer. The matter has been consolidated with a MDL in the Eastern District of Pennsylvania. As to Greenstone and Pfizer, the complaint alleges anticompetitive conduct in violation of federal and state antitrust laws and state consumer protection laws. In June 2020, the State Attorneys General filed a new complaint against a large number of companies, including Greenstone and Pfizer, making similar allegations, but concerning a new set of drugs. This complaint was transferred to the MDL in July 2020. The MDL also includes civil complaints filed by private plaintiffs and state counties against Pfizer, Greenstone and a significant number of other defendants asserting allegations that generally overlap with those asserted by the State Attorneys General.
Subpoena & Civil Investigative Demand relating to Tris Pharma/Quillivant XR
In October 2018, we received a subpoena from the U.S. Attorney’s Office for the Southern District of New York (SDNY) seeking records relating to our relationship with another drug manufacturer and its production and manufacturing of drugs including, but not limited to, Quillivant XR. We responded to that subpoena in full and have had no communication with the SDNY in connection with the subpoena since June 2019. Additionally, in September 2020, we received a Civil Investigative Demand (CID) from the Texas Attorney General’s office seeking records of a similar nature to those requested by the SDNY. We produced records in response to this request. In November 2023, the investigation culminated in a qui tam litigation brought by the State of Texas. The investigation is now closed.
Government Inquiries relating to Meridian Medical Technologies
In February 2019, we received a CID from the U.S. Attorney’s Office for the SDNY. The CID seeks records and information related to alleged quality issues involving the manufacture of auto-injectors at the Meridian site. In August 2019, we received a HIPAA subpoena issued by the U.S. Attorney’s Office for the Eastern District of Missouri, in coordination with the Department of Justice’s Consumer Protection Branch, seeking similar records and information. We have produced records in response to these and subsequent requests.
U.S. Department of Justice/SEC Inquiry relating to Russian Operations
In June 2019, we received an informal request from the U.S. Department of Justice’s Foreign Corrupt Practices Act (FCPA) Unit seeking documents relating to our operations in Russia. In September 2019, we received a similar request from the SEC’s FCPA Unit. We have produced records pursuant to these requests.
Docetaxel––Mississippi Attorney General Government Investigation
See Legal Proceedings––Product Litigation––Docetaxel––Mississippi Attorney General Government Action above for information regarding a government investigation related to Docetaxel marketing practices.
U.S. Department of Justice Inquiries relating to India Operations
In March 2020, we received an informal request from the U.S. Department of Justice’s Consumer Protection Branch seeking documents relating to our manufacturing operations in India, including at our former facility located at Irrungattukottai in India. In April 2020, we received a similar request from the U.S. Attorney’s Office for the SDNY regarding a civil investigation concerning operations at our facilities in India. We are producing records pursuant to these requests.
U.S. Department of Justice/SEC Inquiry relating to China Operations
In June 2020, we received an informal request from the U.S. Department of Justice’s FCPA Unit seeking documents relating to our operations in China. In August 2020, we received a similar request from the SEC’s FCPA Unit. We have produced records pursuant to these requests.
Zantac––State of New Mexico and Mayor and City Council of Baltimore Civil Actions
See Legal Proceedings––Product Litigation––Zantac above for information regarding civil actions separately filed by the State of New Mexico and the Mayor and City Council of Baltimore alleging various state statutory and common law claims in connection with the defendants’ alleged sale of Zantac in those jurisdictions.
Government Inquiries relating to Biohaven
In June 2022, the U.S. Department of Justice's Commercial Litigation Branch and the U.S. Attorney’s Office for the Western District of New York issued a CID relating to Biohaven. The CID seeks records and information related to, among other things, engagements with healthcare professionals and co-pay coupons cards. In March 2023, the California Department of Insurance issued a subpoena seeking records similar to those requested by the CID. Biohaven is a wholly-owned subsidiary that we acquired in October 2022. We are producing records in response to these requests.

U.S. Department of Justice Inquiry relating to Mexico Operations
In March 2023, we received an informal request from the U.S. Department of Justice’s FCPA Unit seeking documents relating to our operations in Mexico. We are producing records pursuant to this request.
Government Inquiries relating to Xeljanz
In April 2023, we received a HIPAA subpoena issued by the U.S. Attorney’s Office for the Western District of Virginia, in coordination with the Department of Justice’s Commercial Litigation Branch, seeking records and information related to programs Pfizer sponsored in retail pharmacies relating to Xeljanz. We are producing records pursuant to this request.
B. Guarantees and Indemnifications
In the ordinary course of business and in connection with the sale of assets and businesses and other transactions, we often indemnify our counterparties against certain liabilities that may arise in connection with the transaction or that are related to events and activities prior to or following a transaction. If the indemnified party were to make a successful claim pursuant to the terms of the indemnification, we may be required to reimburse the loss. These indemnifications are generally subject to various restrictions and limitations. Historically, we have not paid significant amounts under these provisions and, as of December 31, 2023, the estimated fair value of these indemnification obligations is not material to Pfizer. See Note 2C for a description of the March 2022 indemnity provided by Pfizer to GSK in connection with the issuance of notes by the Consumer Healthcare JV. In conjunction with the completion of GSK’s demerger transactions in July 2022, GSK’s guarantee and our related indemnification of GSK’s guarantee were terminated.
In addition, in connection with our entry into certain agreements and other transactions, our counterparties may be obligated to indemnify us. For example, our global agreement with BioNTech to co-develop a mRNA-based coronavirus vaccine program aimed at preventing COVID-19 infection, includes certain indemnity provisions pursuant to which each of BioNTech and Pfizer has agreed to indemnify the other for certain liabilities that may arise in connection with certain third-party claims relating to Comirnaty.
SeeNote 7Dfor information on Pfizer Inc.’s guarantee of the debt issued by PIE in May 2023.
We have also guaranteed the long-term debt of certain companies that we acquired and that now are subsidiaries of Pfizer. See Note 7D.
C. Certain Commitments
As of December 31, 2023, we had commitments totaling $5.2 billion that are legally binding and enforceable. These commitments include payments relating to potential milestone payments deemed reasonably likely to occur, and purchase obligations for goods and services.
See Note 5A for information on the TCJA repatriation tax liability.
D. Contingent Consideration for Acquisitions
We may be required to make payments to sellers for certain prior business combinations that are contingent upon future events or outcomes. See Note 1D. The estimated fair value of contingent consideration as of December 31, 2023 is $692 million, of which $179 million is recorded in Other current liabilities and $512 million in Other noncurrent liabilities, and as of December 31, 2022 was $645 million, of which $42 million was recorded in Other current liabilities and $603 million in Other noncurrent liabilities. The increase in the contingent consideration balance from December 31, 2022 is primarily due to fair value adjustments, partially offset by payments made upon the achievement of certain sales-based milestones.
E. Insurance
Our insurance coverage reflects market conditions (including cost and availability) existing at the time it is written, and our decision to obtain insurance coverage or to self-insure varies accordingly. Depending upon the cost and availability of insurance and the nature of the risk involved, the amount of self-insurance may be significant. The cost and availability of coverage have resulted in self-insuring certain exposures, including product liability.If we incur substantial liabilities that are not covered by insurance or substantially exceed insurance coverage and that are in excess of existing accruals, there could be a material adverse effect on our cash flows or results of operations in the period in which the amounts are paid and/or accrued.
Note 17.Segment, Geographic and Other Revenue Information
A. Segment Information
We regularly review our operating segments and the approach used by management to evaluate performance and allocate resources. In 2023, we managed our commercial operations through two operating segments, each led by a single manager: Biopharma, our innovative science-based biopharmaceutical business, and Business Innovation, an operating segment established in the first quarter of 2023 that includes PC1, our contract development and manufacturing organization and a leading supplier of specialty active pharmaceutical ingredients, and Pfizer Ignite, an offering that provides strategic guidance and end-to-end R&D services to select innovative biotech companies that align with Pfizer’s R&D focus areas. Biopharma is the only reportable segment. Each operating segment has responsibility for its commercial activities. Regional commercial organizations market, distribute and sell our products and are supported by global platform functions that are responsible for the research, development, manufacturing and supply of our products and global corporate enabling functions. Each operating segment has a geographic footprint across developed and emerging markets. Our chief operating decision maker uses the revenues and earnings of the operating segments, among other factors, for performance evaluation and resource allocation. Beginning in July 2023, in consideration of planned future investments in oncology, including the December 2023 acquisition of Seagen, we reorganized our R&D platform operations. Discovery to late-phase clinical development for oncology is performed by a new end-to-end ORD organization and discovery to late-phase clinical development for all remaining therapeutic areas is consolidated into the end-to-end PRD organization. ORD and PRD replace our former WRDM and GPD organizations, where, prior to July 2023, research units within WRDM were generally responsible for research and early-stage development assets and, prior to July 2023, GPD was generally responsible for the clinical development strategy and operational execution of clinical trials for both early- and late-stage clinical assets in Pfizer’s pipeline. In 2023, Biopharma received R&D services from

Pfizer Inc.2023 Form 10-K102


Notes to Consolidated Financial Statements
Pfizer Inc. and Subsidiary Companies
ORD, PRD and the predecessor WRDM and GPD organizations. These services included IPR&D projects for new investigational products and additional indications for in-line products.
Other Business Activities––Other business activities include the operating results of Business Innovation as well as certain pre-tax costs not allocated to our operating segment results, such as costs associated with:
ORD––the R&D expenses managed by our ORD organization, which is responsible for discovery to late-phase clinical development for oncology research projects for our global Biopharma portfolio along with facilitating regulatory submissions and interactions with regulatory agencies for these projects. R&D spending may include upfront and milestone payments for intellectual property rights for oncology projects.
PRD––the R&D expenses managed by our PRD organization, which is responsible for discovery to late-phase clinical development research projects for all therapeutic areas other than oncology for our global Biopharma portfolio, along with facilitating regulatory submissions and interactions with regulatory agencies for these projects. R&D spending may include upfront and milestone payments for intellectual property rights related to non-oncology projects. The PRD organization also has responsibility for certain science-based and other platform-services organizations, which provide end-to-end technical expertise and other services to both ORD and PRD R&D projects, as well as the Worldwide Medical and Safety group, which helps ensure that Pfizer provides all stakeholders––including patients, healthcare providers, pharmacists, payors and health authorities––with complete and up-to-date information on the risks and benefits associated with Pfizer products so that they can make appropriate decisions on how and when to use Pfizer’s medicines.
Corporate and other unallocated––the costs associated with (i) corporate enabling functions (such as digital, global real estate operations, legal, finance, human resources, worldwide public affairs, compliance and worldwide procurement, among others) and other corporate costs, including, but not limited to, all strategy, business development and portfolio management capabilities and certain compensation, as well as interest income and expense, and gains and losses on investments; (ii) overhead costs primarily associated with our manufacturing operations (which include manufacturing variances associated with production) that are not directly assessed to an operating segment, as business unit (segment) management does not manage these costs; and (iii) our share of earnings from Haleon/the Consumer Healthcare JV.
Reconciling Items––The following items, transactions and events are not allocated to our operating segment results: (i) all amortization of intangible assets; (ii) acquisition-related items, where we incur costs for executing the transaction, integrating the acquired operations and restructuring the combined company, and which may also include purchase accounting impacts, such as the incremental charge to cost of sales from the sale of acquired inventory that was written up to fair value, depreciation related to the increase/decrease in fair value of acquired fixed assets, amortization related to the increase in fair value of acquired debt, and the fair value changes for contingent consideration; and (iii) certain significant items, representing substantive and/or unusual, and in some cases recurring, items that are evaluated on an individual basis by management and that, either as a result of their nature or size, would not be expected to occur as part of our normal business on a regular basis. Such certain significant items can include, but are not limited to, pension and postretirement actuarial remeasurement gains and losses, non-acquisition-related restructuring costs, net gains and losses on investments in equity securities, as well as costs incurred for legal settlements, asset impairments and disposals of assets or businesses, including, as applicable, any associated transition activities.
Segment Assets––We manage our assets on a total company basis, not by operating segment, as our operating assets are shared or commingled. Therefore, our chief operating decision maker does not regularly review any asset information by operating segment and, accordingly, we do not report asset information by operating segment. Total assets were $227 billion as of December 31, 2023 and $197 billion as of December 31, 2022.

C. Other Revenue Information
Significant Customers
We and our collaboration partner, BioNTech, have entered into agreements to supply pre-specified doses of Comirnaty with multiple developed and emerging nations around the world and are continuing to deliver doses of Comirnaty under such agreements. This includes supply agreements entered into in November 2020 and February and May 2021 with the EC for Comirnaty on behalf of the different EU member states and certain other countries. Each EU member state submits its own Comirnaty vaccine order to us and is responsible for payment pursuant to terms of the supply agreements negotiated by the EC. In May 2023, we and BioNTech amended our contract with the EC to deliver COVID-19 vaccines to the EU. The amended agreement includes rephasing of delivery of doses annually through 2026 and an aggregate volume reduction, providing additional flexibility for those EU member states who agreed to the amended agreement. The EC will maintain access to future adapted COVID-19 vaccines and the ability to donate doses, in alignment with the original agreement.
In 2022 and 2023, we had entered into agreements to supply pre-specified treatment courses of Paxlovid with government and government sponsored customers in multiple developed and emerging nations around the world, which represented most Paxlovid revenues in 2022 and 2023, while commercialization began in some markets in 2023. In October 2023, we announced an amended agreement with the U.S. government, which facilitated the transition of Paxlovid to traditional commercial markets starting in November 2023, with prices negotiated with commercial payors and a copay assistance program for eligible privately insured patients, as the U.S. government began to discontinue the distribution of EUA-labeled Paxlovid. We ensured commercial readiness by providing NDA-labeled commercial supply by the end of 2023. However, EUA-labeled Paxlovid remained available free-of-charge to all eligible patients until the end of 2023, and therefore, there was only minimal uptake of NDA-labeled commercial product before January 1, 2024. In connection with this agreement, we recorded a non-cash revenue reversal of $3.5 billion in the fourth quarter of 2023, of which a portion was associated with sales recorded in 2022, related to the expected return of an estimated 6.5 million treatment courses of EUA-labeled U.S. government inventory. We will convert these treatment courses previously purchased by the U.S. government to a volume-based credit, based on the actual number of treatment courses that are returned by the U.S. government, which will support continued access to Paxlovid through a U.S. government patient assistance program operated by Pfizer. Therefore, we expect the patient assistance program will provide an estimated 6.5 million treatment courses of FDA-approved, NDA-labeled Paxlovid free of charge to all eligible uninsured, Medicare and Medicaid patients through 2024, and to eligible uninsured and underinsured patients through 2028. We also agreed to create, in 2024, a U.S. Strategic National Stockpile of 1.0 million treatment courses to enable future pandemic preparedness through 2028, which will be managed and supplied by Pfizer at no cost to the U.S. government or taxpayers. While we will recognize revenue as the estimated 7.5 million treatment courses are delivered, there is no remaining cash consideration for these treatment courses.
The following summarizes revenue, as a percentage of Total revenues, for our three largest U.S. wholesaler customers and the U.S. government, which was concentrated in our Biopharma operating segment:

(a) The decrease in revenues from the U.S. government as a percentage of Total revenues for 2023 compared to 2022 was primarily due to the transition of Comirnaty and Paxlovid to commercial market sales in the second half of 2023 as well as the revenue reversal for Paxlovid in the fourth quarter of 2023.

Effective June 30, 2023, Merck KGaA took full control of the global commercialization of Bavencio. Beginning in the third quarter of 2023, the related profit share was replaced by a 15% royalty to Pfizer on net sales of Bavencio, which was recorded in Other (income)/deductions––net. We and Merck KGaA continue to operationalize our respective ongoing clinical trials for Bavencio; and Merck KGaA controls all future R&D activities. Bavencio is a registered trademark of Merck KGaA.

(g)See Note 17A above for information about Business Innovation. Prior-period financial information has been revised to reflect the current period presentation.
(h)PC1 includes revenues from our contract manufacturing, including certain Comirnaty-related manufacturing activities performed on behalf of BioNTech ($33 million for 2023, $188 million for 2022, and $320 million for 2021), and revenues from our active pharmaceutical ingredient sales operation, as well as revenues related to our manufacturing and supply agreements with former legacy Pfizer businesses/partnerships.
Remaining Performance Obligations––Contracted revenue expected to be recognized from remaining performance obligations for firm orders in long-term contracts to supply Comirnaty and Paxlovid to our customers totaled approximately $6 billion and $3.4 billion, respectively, as of December 31, 2023, which includes amounts received in advance and deferred, as well as amounts that will be invoiced as we deliver these products to our customers in future periods. Of these amounts, current contract terms provide for expected delivery of product with contracted revenue from 2024 through 2028, the timing of which may be renegotiated. Remaining performance obligations are based on foreign exchange rates as of the end of our fiscal fourth quarter of 2023 and exclude arrangements with an original expected contract duration of less than one year. Remaining performance obligations associated with contracts for other products and services were not significant as of December 31, 2023 or 2022.
Deferred Revenues––Our deferred revenues primarily relate to advance payments received or receivable from various government or government sponsored customers for supply of Paxlovid and Comirnaty.
The deferred revenues related to Paxlovid totaled $3.4 billion as of December 31, 2023, with $1.5 billion and $1.9 billion recorded in current liabilities and noncurrent liabilities, respectively, while deferred revenues related to Paxlovid were not material as of December 31, 2022. The increase in Paxlovid deferred revenues during 2023 was primarily driven by the reversal of Paxlovid revenues and conversion of previously purchased EUA-labeled Paxlovid treatment courses into a volume-based credit under our October 2023 amended agreement with the U.S. government.

Pfizer Inc.2023 Form 10-K106


Notes to Consolidated Financial Statements
Pfizer Inc. and Subsidiary Companies
The deferred revenues related to Comirnaty totaled $1.7 billion as of December 31, 2023, with $1.1 billion and $552 million recorded in current liabilities and noncurrent liabilities, respectively. The deferred revenues related to Comirnaty totaled $2.5 billion as of December 31, 2022, with $2.4 billion and $77 million recorded in current liabilities and noncurrent liabilities, respectively. The decrease in Comirnaty deferred revenues during 2023 was primarily the result of amounts recognized in Product revenues as we delivered the products to our customers, partially offset by additional advance payments received as we entered into amended contracts, as well as the impact of foreign exchange. During 2023, we recognized revenue of approximately $2.2 billion that was included in the balance of Comirnaty deferred revenues as of December 31, 2022.
The Paxlovid and Comirnaty deferred revenues as of December 31, 2023 will be recognized in Product revenues proportionately as we transfer control of the products to our customers and satisfy our performance obligations under the contracts, with the amounts included in current liabilities expected to be recognized in Product revenues within the next 12 months, and the amounts included in noncurrent liabilities expected to be recognized in Product revenues from December 2024 (which falls in our international first quarter of 2025) through 2028. Deferred revenues associated with contracts for other products were not significant as of December 31, 2023 or 2022.

Based on this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures are effective in alerting them in a timely manner to material information required to be disclosed in our periodic reports filed with the SEC.

Internal Control over Financial Reporting

Management’s report on the Company’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act), and the related report of our independent registered public accounting firm, are included in our 2017 Financial Report under the headings Management’s Report on Internal Control Over Financial Reporting and Report of Independent Registered Public Accounting Firm on Internal Control Over Financial Reporting, respectively, and are incorporated by reference.

Changes in Internal Controls


DuringOn December 14, 2023, we acquired Seagen. Other than the addition of Seagen’s operations to our most recent fiscal quarter,internal control over financial reporting and any related changes in control to integrate Seagen into Pfizer, there has not been any change in the Company’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Report of Independent Registered Public Accounting Firm
To the Board of Directors and Shareholders
Pfizer Inc.:

Opinion on Internal Control Over Financial Reporting
We have audited Pfizer Inc. and Subsidiary Companies’ (the Company) internal control over financial reporting as of December 31, 2023, based on criteria established in Internal ControlIntegrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2023 and 2022, the related consolidated statements of income, comprehensive income, equity, and cash flows for each of the years in the three-year period ended December 31, 2023, and the related notes (collectively, the consolidated financial statements), and our report dated February 22, 2024 expressed an unqualified opinion on those consolidated financial statements.
The scope of management’s assessment of the effectiveness of internal control over financial reporting includes all of the Company’s consolidated operations except for the operations of Seagen Inc. and its subsidiaries (Seagen), which the Company acquired on December 14, 2023. Seagen’s operations represent 0.2% of the Company’s consolidated revenues for the year ended December 31, 2023, and assets associated with Seagen’s operations represent 22% of the Company’s consolidated total assets, as of December 31, 2023. Our audit of internal control over financial reporting of the Company also excluded an evaluation of the internal control over financial reporting of Seagen.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

We prepared and are responsible for the financial statements that appear in this Form 10-K. These financial statements are in conformity with accounting principles generally accepted in the United States of America and, therefore, include amounts based on informed judgments and estimates. We also accept responsibility for the preparation of other financial information that is included in this document.
Report on Internal Control Over Financial Reporting
The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. The Company’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States of America. The Company’s internal control over financial reporting includes those policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate. Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2023. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework(2013). Based on our assessment and those criteria, management believes that the Company maintained effective internal control over financial reporting as of December 31, 2023.
The scope of management’s assessment of the effectiveness of internal control over financial reporting includes all of the Company’s consolidated operations except for the operations of Seagen Inc. and its subsidiaries (Seagen), which the Company acquired on December 14, 2023. Seagen’s operations represent 0.2% of the Company’s consolidated revenues for the year ended December 31, 2023, and assets associated with Seagen’s operations represent 22% of the Company’s consolidated total assets, as of December 31, 2023.
The Company’s independent auditors have issued their auditors’ report on the Company’s internal control over financial reporting. That report appears above in this Form 10-K.
