      "prior_body": "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 Pfizer Inc.2023 Form 10-K11 Pfizer Inc.2023 Form 10-K11 2023 Form 10-K 11 Pfizer Inc.2023 Form 10-K11 Pfizer Inc.2023 Form 10-K11 2023 Form 10-K 11 Pfizer Inc.2023 Form 10-K11 2023 Form 10-K 11 2023 Form 10-K 11 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 Factors—Development, Regulatory Approval and Marketing of Products and —Post-Authorization/Approval Data sections. 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 system by changing the way 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 Veterans Administration and the 340B Drug Pricing Program (340B Program). We also must report specific prices to government agencies. The calculations necessary to determine the prices reported are complex and the failure to do so accurately may expose us to enforcement measures. See the discussion regarding rebates in the Product Revenue Deductions section within MD&A and Note 1G. The drug pricing provisions of the IRA, which was signed into law in August 2022, began to be implemented in 2022 and implementation will continue over the next several years. The IRA includes several provisions to lower prescription drug costs for Medicare patients and to reduce drug spending by the federal 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 offered under the 340B Program ceiling price calculation. In addition, there will be a new Medicare manufacturer discount program agreement expected to be 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 legal challenges and therefore, the outcome of the Program remains uncertain. 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. 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 340B Program are undergoing Pfizer Inc.2023 Form 10-K12 Pfizer Inc.2023 Form 10-K12 Pfizer Inc.2023 Form 10-K12 2023 Form 10-K 12 Pfizer Inc.2023 Form 10-K12 Pfizer Inc.2023 Form 10-K12 2023 Form 10-K 12 Pfizer Inc.2023 Form 10-K12 2023 Form 10-K 12 2023 Form 10-K 12 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 has 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 Factors—Pricing and Reimbursement section. States seek to control healthcare costs 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 continue 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 business if implemented. Further, commercial payors often follow Medicare coverage and 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 Factors—Managed 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 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 U.S. New Drug Approvals. In the EU, the EMA conducts the scientific evaluation, supervision and safety monitoring of our innovative medicinal products that are eligible for the centralized marketing authorization procedure. Through the centralized procedure, pharmaceutical companies may submit to the EMA a single application for a marketing authorization valid in all the EU and the European Economic Area (EEA) countries. The EC takes a legally binding decision based on the EMA's recommendation. For medicinal products that are not eligible for the centralized procedure, the mutual recognition procedure is based on the recognition of a pre-existing national marketing authorization by one or more EU member states, and the decentralized procedure allows the submission of a marketing authorization application simultaneously in several EU member states. In the U.K., the Medicines and Healthcare Products Regulatory Agency is the sole regulatory authority. In Japan, the Pharmaceuticals and Medical Device Agency is involved in a wide range of regulatory activities, including clinical studies, approvals, post-marketing reviews and pharmaceutical safety. In China, the National Medical Product Administration is the primary regulatory authority for approving and supervising medicines. Health authorities in many middle- and lower-income countries might require marketing approval or scientific opinions by a recognized regulatory authority (e.g., the FDA or 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 revise the EU pharmaceutical legislation. The proposed legislation includes a significant focus on tackling inequalities on access, affordability and availability of medicines across the EU. The legislative process is ongoing and when eventually completed, it is likely to be the largest reform in over 20 years to EU medicines regulation, with a wide range of impacts including on approval procedures, regulatory data protection and environmental protection measures. Pharmacovigilance. In the EU, the EMA’s PRAC is responsible for reviewing and making recommendations on product safety issues. Specifically, the PRAC focuses on detecting, assessing and communicating the risks associated with adverse reactions of medicinal products, while considering their therapeutic effects. It also evaluates post-authorization safety studies and conducts pharmacovigilance audits. Outside developed markets, pharmacovigilance requirements vary and are generally not as extensive, but there is a trend toward increasing regulation. Pricing and Reimbursement. Certain governments, including in the different EU member states, the U.K., Japan, China, Canada and South Korea, provide healthcare at low-to-zero direct cost to consumers at the point of care and have significant power to regulate pharmaceutical Pfizer Inc.2023 Form 10-K13 Pfizer Inc.2023 Form 10-K13 Pfizer Inc.2023 Form 10-K13 2023 Form 10-K 13 Pfizer Inc.2023 Form 10-K13 Pfizer Inc.2023 Form 10-K13 2023 Form 10-K 13 Pfizer Inc.2023 Form 10-K13 2023 Form 10-K 13 2023 Form 10-K 13 prices or patient reimbursement levels to control costs for the government-sponsored healthcare system, particularly under recent global financing pressures. Governments globally may use a variety of measures to control costs, including, among others, legislative or regulatory pricing reforms, 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. In addition, the international patchwork of price regulation, differing economic conditions and incomplete value assessments across countries has led to varying access to quality medicines in many markets and some third-party trade in our products between countries. Several important multilateral organizations such as the WHO scrutinize international pharmaceutical pricing through policy recommendations and sponsorship of programs, such as “The Oslo Medicines Initiative” (OMI) which aims to ensure “affordability for high-priced medicines”. The OMI concluded its work in September 2022, and the WHO/Europe Access to Novel Medicines Platform was established to enhance affordable and equitable access to effective, innovative and high-priced medicinal products in the region. In China, pricing pressures have increased in recent years because of an overall focus on healthcare cost containment with the central government emphasizing 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 result of adding innovative drugs (including oncology medicines, medicines for children and orphan drugs) to the National Reimbursement Drug List via access-price negotiation. A centralized VBP program with a tendering process aims to contain healthcare costs by driving utilization of generics that have passed QCE. This has resulted in further lowering the price of medicines, especially off-patent medicines; this trend is expected to continue. China is increasing its use of Health Technology Assessment and is controlling mark-ups within the country using a two-invoice limited system, which is a government policy that regulates the pricing of pharmaceutical products and medical devices. Pfizer, along with most off-patent originators, have mostly not been successful in the VBP 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 Vfend 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 future QCE expansion have been made available, we are unable to determine the impact on our business of the various pricing measures underway. Healthcare Provider Transparency and Disclosures. Several countries have implemented laws requiring (or industry trade associations have recommended) disclosure of transfers of value made by pharmaceutical companies to healthcare providers and/or healthcare organizations, such as academic teaching hospitals. Intellectual Property. Reliable patent protection and enforcement around the world are among the key factors we consider for continued business and R&D investment. The WTO Agreement on Trade Related Aspects of Intellectual Property Rights (WTO-TRIPS) requires participant countries to provide patent and other intellectual property-related protection for pharmaceutical products by law, with a 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 in many countries. While the global intellectual property policy environment has generally improved following implementation of WTO-TRIPS and bilateral/multilateral trade agreements, our 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, governments have used intellectual property policies as a tool to force innovators to accept less than fair value for medicines, as well as to advance 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 has weakened current intellectual property protection in some countries and 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, revocation of patents, laws or regulations that promote or provide broad discretion to issue a compulsory license, weak intellectual property enforcement and failure to implement effective regulatory data protection. Our industry advocacy efforts focus on seeking a fair and transparent business environment for foreign manufacturers, underscoring the importance of strong intellectual property systems for all innovative industries (both domestic and foreign) and helping improve patients’ access to innovative medicines and vaccines. Data Privacy. We are subject to extensive privacy and data protection laws and regulations around the world concerning the collection, use and sharing of personal data. 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 fines and penalties are also increasing. 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."

We have made, and intend to continue to make, the expenditures necessary for compliance with applicable laws. We also are cleaning up environmental contamination from past industrial activity at certain sites. We incurred capital and operational expenditures in 2023 for environmental compliance purposes and for the clean-up of certain past industrial activity as follows: $92 million in environment-related capital expenditures and $158 million in other environment-related expenses. While capital expenditures or operating costs for environmental compliance cannot be predicted with certainty, we do not currently anticipate they will have a material effect on our capital expenditures or financial position. See also Note 16A3. As a science guided organization, we take a proactive approach to our environmental sustainability initiatives. In 2022, we announced a new goal to further reduce greenhouse gas (GHG) emissions and achieve the Science Based Target Initiative’s voluntary Net-Zero Standard by 2040. 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 investing in new technologies and innovative climate solutions, and setting expectations for our suppliers to establish science-aligned GHG emission reduction goals.

For a discussion of the risks associated with climate change and our environmental initiatives, see the Item 1A. Risk Factors—Climate Change and Sustainability section. OUR PEOPLE Our purpose is: Breakthroughs that change patients’ lives. These breakthroughs are delivered through the collaboration of our talented workforce. As of December 31, 2023, including Seagen colleagues, we employed approximately 88,000 people worldwide, with approximately 35,000 based in the U.S. Women 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 commitment, 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 colleague experience is of utmost importance, particularly during times of business transformation. We were conscious of the impact that the challenges and opportunities 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 of 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 face of uncertainty or adversity. This happens when we think big, speak up and are 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 measure 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 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 lens 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 to 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 survey 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.

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, Health & Safety (EHS) Policy and 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. Pay Equity. Our commitment to pay equity for all colleagues is based in our value of Equity and our intention to continue to build a diverse, inclusive and highly motivated workforce. We are committed to equitable pay practices at Pfizer for employees based on role, education, experience, performance, and location and we conduct and report publicly on pay equity on an annual basis. ITEM 1A.RISK FACTORS This section describes the material risks to our business, which should be considered carefully in addition to the other information in this report and our other filings with the SEC. Investors should be aware that it is not possible to predict or identify all such factors and that the following is not meant to be a complete discussion of all potential risks or uncertainties. Additionally, our business is subject to general risks applicable to any company, such as economic conditions, geopolitical events, extreme weather and natural disasters. If known or unknown risks or uncertainties materialize, our business operations, financial condition, operating results (including components of our financial results), cash flows, prospects, reputation or credit ratings could be adversely affected now and in the future, potentially in a material way. The following discussion of risk factors contains forward-looking statements, as discussed in the Forward-Looking Information and Factors that May Affect Future Results section."

In addition, we have been and may in the future be subject to claims and other actions related to our business activities, brought by governmental authorities, as well as consumers and private 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. Such claims, actions and inquiries may relate to alleged non-compliance with laws and regulations associated with the dissemination of product (approved and unapproved) information, potentially resulting in government enforcement action and reputational damage.

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-time received, and may receive in the future, inquiries and subpoenas and other types of information demands from government authorities. In addition, we have been subject to claims and other actions related to our business activities, brought by governmental authorities, as well as consumers and private 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. Such claims, actions and inquiries may relate to alleged non-compliance with laws and regulations associated with the dissemination of product (approved and unapproved) information, potentially resulting in government enforcement action and reputational damage. This risk may be heightened by digital marketing, including social media, mobile applications and blogger outreach. 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. We and certain of our subsidiaries are also subject to numerous contingencies arising in the ordinary course of business relating to legal claims and proceedings, including environmental contingencies. 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.

As the U.S. private third-party payor market consolidates further, and as the IRA prices become publicly available, we may face greater pricing pressure from private third-party payors as they continue to drive more of their patients to use lower cost alternatives or seek even larger rebates to control costs or offset losses from the IRA.

Transitional risks include, for example, a 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 GHG emissions, and increased GHG 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 our 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 medicines for patients.

In addition to the expansion of price controls in the U.S. in the IRA, the adoption of more restrictive coverage policies and price controls in new and existing jurisdictions, or the failure to obtain or maintain coverage and pricing could also adversely impact revenue. We expect pricing pressures and other cost containment measures for drugs and vaccines will continue. In the U.S., pharmaceutical product pricing is subject to government and public scrutiny and calls for reform, and many of our products are subject to increasing pricing pressures as a result. We expect to see continued focus by the U.S. government on regulating pricing and access to medicine. For example, the drug pricing provisions of the IRA are being implemented over the next several years. The IRA directs HHS to set the prices of certain high-expenditure, single-source drugs and biologics covered under Medicare. The IRA also imposes rebates under Medicare Part B and Medicare Part D which require manufacturers to pay rebates if price increases outpace inflation relative to a benchmark period, and replaces the Medicare 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 will continue in coming years. In August 2023, CMS published the first ten medicines subject to the MDPNP, which included Eliquis. In August 2024, the government released the new Medicare price for Eliquis, which will become effective January 1, 2026. On January 17, 2025, CMS announced the selection of another 15 drugs from Medicare Part D for the maximum fair price, with prices to be set and effective on January 1, 2027. Ibrance and Xtandi were included in the list of 15 drugs selected. Another 15 drugs from Medicare Part B or Medicare Part D will be selected by February 1, 2026, for the maximum price to be set and in effect by January 1, 2028. It is possible that more of our products could be selected in future years, which could, among other things, lead to lower revenues prior to expiry of intellectual property protections. Health plans may also require rebates in addition to the maximum fair price for preferred placement on a Medicare plan formulary. The MDPNP is currently subject to legal challenges and therefore, the outcome remains uncertain. 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. For additional information, see the Item 1. Business—Government Regulation and Price Constraints section. Payors may give preference to 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 others are considering, patient access constraints or cost cutting under state regulated programs including the Medicaid program. States have continued to focus on addressing drug costs, generally by increasing price transparency or attempting to limit drug price increases for state-regulated insurance. Measures to regulate prices or payment for pharmaceutical products, including legislation on drug importation and prescription drug affordability boards (PDABs) that seek to impose reimbursement limits for certain drugs, could adversely affect our business. For additional information on U.S. pricing and reimbursement, see the Item 1. Business—Government Regulation and Price Constraints section. We encounter similar regulatory and legislative issues in most other countries in which we operate. In certain markets, such as in EU member states, the U.K., Japan, China, Canada, Australia and New Zealand, governments have significant power as large single payors to regulate prices, access criteria, or impose other means of cost control, particularly as a result of recent global financing pressures. For example, the QCE and VBP tender process in China has resulted in significant price cuts for off-patent medicines. Additionally, in the EU, the EC proposed the largest reform of EU pharmaceutical legislation in 20 years. In April 2024, the European Parliament introduced amendments to the EC’s proposal. The EU legislative process remains ongoing, with several stages still required before the reform can receive final approval. This reform may alter Pfizer Inc.2024 Form 10-K18 Pfizer Inc.2024 Form 10-K18 Pfizer Inc.2024 Form 10-K18 2024 Form 10-K 18 regulatory exclusivity periods for our products and may add burdensome obligations that impact access. In addition, with the European Regulation on Health Technology Assessment (EU HTA-R) taking effect in January 2025, we are engaging and monitoring application of the EU’s new clinical assessment program to new oncology products and certain biologic products submitted to the EMA. For additional information regarding these government initiatives, see the Item 1. Business—Government Regulation and Price Constraints section. We anticipate that these and similar initiatives will continue to increase pricing and access pressures globally. In addition, in many countries, with respect to our vaccines, we participate in a tender process for selection in national immunization programs.

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

As such, IPR&D assets may become impaired and/or be written off in the future if the associated R&D effort is abandoned or is curtailed. For goodwill, all reporting units can confront events and circumstances that can lead to a goodwill impairment charge such 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 market exclusivity. Our other intangible assets, including developed technology rights and brands, face similar risks for impairment. Our equity-method investments may also be subject to impairment charges that may result from the occurrence of unexpected adverse events or management decisions that impact our estimates of expected cash flows to be generated from these investments. We may recognize impairment charges as a result of a weak economic environment, challenging market conditions, decisions by management, or events related to particular customers or asset types, such as the development of competing assets by us or others, regulatory actions or product recalls or withdrawals. Any such impairment charge of our intangible assets, goodwill and equity-method investments may be significant. See Note 4 for a discussion of recent impairments of intangible assets.

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 monitor the global trade environment and potential trade conflicts, sanctions and impediments that could impact our business. 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 pension plan investments; required increases of our pension funding obligations; increased government cost control efforts; delays or failures 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. In addition, issued or future executive orders or other new or changes in laws, regulations or policy regarding tariffs, could have a material adverse effect on our business, earnings and financial guidance. The actual impact of the new tariffs on our business is subject to a number of factors including, but not limited to, restrictions on trade, the effective date and duration of such tariffs, countries included in the scope of tariffs, changes to amounts of tariffs, and potential retaliatory tariffs imposed by other countries. 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 high 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. In 2024, 39% of our total revenues were derived from international operations, including 19% from Europe and 13% from China, Japan 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 are subject to risk from changes in interest and exchange rates. The risks related to interest-bearing investments and borrowings and the measures we have taken to help contain them are discussed in the Analysis 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 and Note 11."

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 additional information on U.S. healthcare regulation, see the Item 1. Business––Government Regulation and Price Constraints 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 to the U.S. at prices that are regulated by foreign governments, revisions to reimbursement of biopharmaceuticals under government programs that could reference international prices or require new discounts, limitations on interactions with healthcare professionals and other industry stakeholders, restrictions on pharmaceutical advertising, 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. In addition, we may face increased risks to, among other things, our business, revenue, earnings, reputation or financial guidance, as a result of potential changes to vaccine or other healthcare policy in the U.S. Any additional reduction of U.S. federal spending on entitlement programs beyond the IRA, including Medicare, Medicaid, or any other publicly funded or subsidized health programs, and the 340B Program, may affect payment for our products or services provided using our products. Any 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. The IRA is being 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 expect additional drug cost containment efforts at both the federal and state levels. 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 future."

      "current_body": "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) program. Management is responsible for assessing and managing risk, including through the ERM program, subject to oversight by our BOD. Our cybersecurity policies and practices are aligned with NIST (National Institute of Standards and Technology) 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 relevant 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 appropriate. This includes identifying cybersecurity risks presented by third parties. •Incident Response Planning: We have established, and maintain and periodically test, incident response plans that direct our response to cybersecurity events and incidents. Such plans include the protocol by which certain significant or potentially material incidents would be communicated to executive management, our BOD, external regulators and shareholders, as appropriate. •Enterprise-Wide Coordination: We engage relevant stakeholders 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.

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. 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 could 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 by the Chief Information Security Officer (CISO) to certain senior leaders, 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 periodic briefings on, and discusses with our CISO, 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 certain significant or potentially material cybersecurity incidents that may occur, including any ongoing updates regarding the same. 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. We believe our CISO and the information security organization have the appropriate expertise, background and depth of experience relating to monitoring the prevention, mitigation, detection and remediation of cybersecurity incidents to manage risks arising from cybersecurity threats. The CISO works in coordination with other members of the management team, including, among others, the Chief Digital Officer, the Chief Financial Officer and the Chief Legal Officer and their designees. 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. For the fiscal year ended December 31, 2024, 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. 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."

      "current_body": "Significant disruptions of IT systems or breaches of information security could adversely affect our business. We extensively rely upon sophisticated IT systems (including cloud services) to operate our business. We produce, collect, process, store and transmit large amounts of confidential information (including personal information and intellectual property), and we deploy and operate an array of technical and procedural controls to maintain the confidentiality, integrity and availability of such confidential information. We develop 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, including significant elements of our IT infrastructure and, as a result, we manage relationships with many 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 IT and information security systems, and those of our third-party providers (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 malicious attackers. As a global pharmaceutical company, our systems and assets are the target of frequent cyber-attacks. Such cyber-attacks are of ever-increasing levels of sophistication, including the use of adversarial AI techniques, and are made by groups and individuals with a wide range of motives (including, but not limited to, industrial 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. 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 IT and develop and maintain systems and controls, our efforts, like those of other similar companies, have not always and may not in the future prevent service interruptions, extortion, theft of confidential, personal or proprietary information, compromise of data integrity or unauthorized information disclosure. Any technology service interruption or breach of our systems could adversely affect our business operations and/or result in potential legal liability, the loss of personal data, confidential information or intellectual 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. AI is increasingly being used in the biopharmaceutical and global healthcare industries. As with many developing technologies, AI presents risks and challenges. For example, algorithms may be flawed or trained on content without the necessary intellectual property rights or other legal rights or permissions; data sets may not be appropriate for the intended use, of poor quality, contain biased information, or become corrupted during a cyber-attack; and inappropriate or controversial data practices by data scientists, engineers, and end-users could impair results. If the outputs that AI produces or assists in producing are deficient or inaccurate, we could be subjected to competitive harm, potential legal liability and brand or reputational harm. Furthermore, use of AI may lead to the release of confidential information which may impact our ability to realize the benefits of our data, including intellectual property."
