These networks are available to all issuers and merchants in the U.S.

Our person-to-person payment and account-to-account transfer services allow consumers a convenient way to send and receive money while offering financial institutions the opportunity to generate new transaction-based revenue, attract new accounts and increase loyalty among existing customers. We offer a turnkey implementation of Zelle® real-time person-to-person payments service. Our electronic bill payment and presentment product for financial and other institutions, CheckFree® RXP®, allows our clients’ customers to manage household bills via an easy-to-use, online tool; view billing and payment information; pay and manage their bills in one place; and complete same-day or next-day bill payments to a wide range of billers and others.

This turnkey, easy-to-use accounts receivable and payable solution is created for clients to offer a complete small and medium-sized business (“SMB”) solution to their customers and members to manage their working capital, while our client’s grow deposits, revenue and their SMB portfolio.

Additionally, we offer products and services that enable operating efficiencies and management insight by providing financial institutions with the infrastructure they need to process, route and settle non-card-based electronic payments, including ACH, wire and instant payments, and to efficiently manage associated information flows.

Banking

We provide customer loan and deposit account processing; digital banking; financial and risk management; professional services and consulting; and check processing. The lines between merchant acquiring, payment processing and banking are increasingly interconnected, as more banking and payment transactions are initiated at different touchpoints within merchant engagement.

Account processing solutions enable financial institutions to operate systems that process customer deposit and loan accounts, an institution’s general ledger, central information files and other financial information. These solutions also include security, reporting and other features that financial institutions need to process transactions for their customers. Although many of our clients obtain a majority of their processing requirements from us, our software design allows clients to start with one application and, as needed, add applications and features developed by us or by third parties. We support a broad range of client-owned peripheral devices manufactured by a variety of vendors, which reduce a new client’s initial conversion expenses, enhance existing clients’ ability to change technology and broaden our market opportunity. The principal account processing solutions used by our depository institution clients are DNA®, Finxact, Premier®, CoreAdvance, Portico®, and Signature®. CoreAdvance is our newest solution offering a more flexible architecture, modern user interface, real-time processing, and personalization capabilities, all of which enable increased efficiency. We are embedding artificial intelligence (“AI”) capabilities in our account processing solutions, led by Finxact. All of these solutions are available in the U.S., and the DNA, Finxact and Signature solutions are also available globally. Account processing solutions are offered primarily as an outsourced service or can be installed on client-owned computer systems or those hosted by third parties.

Our principal consumer and business digital banking platform, Experience Digital (“XD”), builds on our Configure™, Architect™, Corillian Online®, Mobiliti™ and Create™ products. XD is a cloud-based platform that enables customers to perform balance inquiries, view their transaction history and access electronic bill payments, person-to-person digital payments, card services, account and loan originations, funds transfer and personal financial management tools. XD can be highly customized and integrated to multiple products and services, allowing clients to deploy new services quickly and efficiently to increase customer acquisition, engagement and insights.

Additionally, our embedded finance solutions enable merchants and others to deliver personalized financial experiences to their customers through a combination of Fiserv solutions including Finxact, Payfare, Commerce Hub™, card manufacturing and processing, as well as third-party services. We have developed a comprehensive end-to-end embedded finance solution that supports various payment flows. This solution is built on a sophisticated ledger powered by Finxact to record transactions between buyers and sellers; an orchestration layer powered by Payfare to manage each transaction; and payment acceptance powered by Commerce Hub. Together, these components support all payment flows for payouts, returns, and reconciliations.

Through our acquisition of StoneCastle Cash Management, we enable our network of depository institutions to easily access stable, cost-efficient deposit funding. This allows us to become a technology-enabled source of institutional deposits, helping financial institutions strengthen their balance sheets by integrating insured deposit products alongside their core account processing, digital banking, payments and cash-management capabilities across the Fiserv ecosystem.

We also help clients create an infrastructure that they can use and deploy to their clients. We are building our stablecoin capabilities with the launch of FIUSD, embedded within our existing banking and payments ecosystem, which allows customers access to more efficient and interoperable digital asset service. Additionally, we offer consulting services, business

Servicing the Market

The financial technology industry is highly dynamic, with new innovations entering the market and driving the expectations of our clients globally. The products and services we offer seek to meet the needs of our clients and their customers, with strong emphasis on quality, security, service reliability, timely introduction of new capabilities and features, flexibility and value. This requires us to continue our focus on product and service delivery, integration and innovation to meet and exceed the specific needs of our clients.

Resources

Our business depends on a variety of resources to operate including products and services provided to us by third parties. For example, we rely on our human capital resources for product development (including product design and coding), sales, operations (including customer service, technology support, and security) and management; access to financial and telecommunication networks; computers, servers, mainframes, microchips and other computer equipment; and Clover and other POS devices. We periodically review our resource requirements and sources, as well as our relationships with key vendors, to meet the needs of our business including global sourcing efforts and alternate supplier resourcing. We believe we have access to the resources necessary for our current business needs. More information regarding supply chain risks can be found under the headings “Operational and Security Risks*”* and “Global Market Risks” in the Risk Factors section of this report and our human capital resources can be found below under the heading “Human Capital.”

Intellectual Property

We regard our hardware, software, transaction processing services and related products as proprietary, and we use a combination of patent, copyright, trademark and trade secret laws, internal security practices, employee confidentiality and assignment agreements, and third-party non-disclosure agreements to protect our intellectual property assets. Our patents cover innovations relating to numerous financial software and hardware products and services, and we continue, where appropriate, to seek and secure patents with respect to our ongoing innovations. We believe that we possess the proprietary rights necessary to conduct our business.

Competition

The market for technology products and services is fragmented, highly competitive, and served by a multitude of large and small businesses. Our principal competitors include other large, integrated providers of financial services technology and payment systems, data processing affiliates of large companies, processing centers owned or operated as user cooperatives, financial institutions, merchant acquirers, ISOs, ISVs, payments companies and payment network operators. Our competitors also include global and local IT product and services companies and payment service providers and processors. We expect competition to continue to increase as new companies enter our markets and existing competitors expand or consolidate their product lines and services. Some of these competitors possess substantial financial, sales and marketing resources and can compete with us in various ways, including through the use of integrated product offerings and through pricing and long-standing relationships. Depending on the product or service, competitive factors may include quality, security, innovation, breadth or novelty of features and functionality, client satisfaction, market opportunity, integration, global reach, multiple distribution channels, service reliability and performance standards, timely introduction of new products and features, platform scalability and flexibility, and value. We believe that we compete favorably in each of these categories. Additional information about competition in our segments is provided below.

Merchant

The products and services in our Merchant segment compete with merchant acquirers and financial institutions that provide acquiring and processing services to businesses on their own. In many cases, our alliance and commercial partners, such as ISOs and ISVs, compete against each other. We also compete with merchant services providers and, in a number of countries outside of the U.S., our Merchant segment competes with a growing number of local and regional providers. In addition, payment networks and large technology, media and other integrated payments software providers are increasingly offering products and services that compete with our suite of merchant acquiring solutions.

Financial

The products and services in our Financial segment compete with large, diversified software and service companies, independent suppliers of software products, businesses that offer consumer and business payment solutions and a number of payment and card issuer processors. In addition to traditional payments competitors, large technology, media and other emerging financial technology providers are increasingly seeking to provide alternative payment and financing solutions. Existing and potential financial institution and other corporate clients could also develop and use their own in-house systems or custom-designed solutions instead of our products and services. In addition, we compete with vendors that offer similar transaction processing products and services to financial institutions.

Government Regulation

Our operations, and the products and services that we offer, are subject to various U.S. federal, state and local regulations, as well as regulations outside the U.S. We are also subject to non-government-issued rules and requirements, such as those promulgated by various payment networks. Failure to comply with these rules and regulations may result in the suspension or

Table of Contents

revocation of licenses or registrations, the limitation, suspension or termination of service and the imposition of civil and criminal penalties, including fines. We may also be required, among other things, to make significant additional investments to comply with rules and regulations, to modify our products or services or the manner in which they are provided, or to limit or change the amount or types of revenue we are able to generate.

Financial Institution Regulations. Because a number of our businesses provide services to regulated financial institutions, we are considered to be a significant service provider under the Bank Service Company Act and, as a result, we are subject to examination by the U.S. Federal Banking Agencies, which are comprised of the Board of Governors of the Federal Reserve System, the Federal Deposit Insurance Corporation, and the Office of the Comptroller of the Currency. We are regulated based on the uniform principles, standards, and guidance created by the Federal Financial Institutions Examination Council (“FFIEC”). The FFIEC is a formal interagency body empowered to standardize and promote uniformity in supervision of financial institutions. The member agencies of the FFIEC include the Federal Reserve Board, the Federal Deposit Insurance Corporation, the Office of the Comptroller of the Currency, the National Credit Union Administration, and the Consumer Financial Protection Bureau (“CFPB”), which are empowered to conduct rule-making and supervision related to, and enforcement of, federal consumer financial laws, some of which apply to products and services offered by our clients.

In the U.S., we are subject to the Dodd-Frank Wall Street Reform and Consumer Protection Act, which, among other things, and in conjunction with the Federal Reserve Board’s Regulation II, caps debit interchange rates for certain debit and prepaid card issuers; prohibits card issuers and payment networks from restricting the ability of merchants to direct the routing of debit card transactions; requires all debit card issuers in the U.S. to participate in at least two unaffiliated debit payment card networks; prohibits payment card networks from restricting debit and prepaid card issuers from contracting with other payment card networks; and generally prohibits network exclusivity arrangements for debit card and prepaid card issuers. These regulations impact our card processing and debit network businesses.

Certain of our subsidiaries hold payment institution or electronic money licenses. These subsidiaries are subject to regulation and oversight in the jurisdictions in which they operate and may be required to meet minimum capital maintenance requirements or other obligations. We are also subject to regulation by the Georgia Department of Banking and Finance in connection with our subsidiary’s Merchant Acquirer Limited Purpose Bank (“MALPB”) in Georgia, by the New Hampshire Banking Department in connection with our subsidiary’s trust company in New Hampshire and by the Colorado Division of Banking in connection with our subsidiary’s trust company in Colorado. In addition, several of our subsidiaries outside of the U.S. provide services such as merchant terminal leasing, debit processing, acquiring, issuing, factoring and settlement that make them subject to regulation by financial services supervisory agencies.

Association and Network Rules. We are subject to the rules of various payment networks, such as Visa and Mastercard. In order to provide processing services, a number of our subsidiaries are registered with Visa and/or Mastercard as service providers for member institutions. Our MALPB subsidiary and a number of our subsidiaries outside the U.S. are direct members or associate members of Visa and Mastercard for purposes of conducting merchant acquiring. Various subsidiaries are also processor level members of other debit and electronic benefits transaction networks or are otherwise subject to various network rules in connection with processing services and other services we provide. As such, we are subject to applicable card association, network and national scheme rules that could subject us to fines or penalties. We are subject to network operating rules promulgated by Nacha relating to payment transactions processed by us using the ACH network and to various federal and state laws regarding such operations, including laws pertaining to electronic benefits transactions.

Privacy and Cybersecurity Regulations. We provide services that involve the collection and processing of significant amounts of personal, financial, and other sensitive data which subject our offerings to various federal, state, local and foreign privacy and cybersecurity laws and regulations, as well as association and network privacy and cybersecurity rules, which govern, among other things, the collection, processing, storage, deletion, use and disclosure of personal information. These laws and rules contain a variety of obligations including the safeguarding of personal information, the provision of notices and use and disclosure rights. The regulations and rules are complex and evolving and can provide for significant penalties or the suspension or termination of our registrations or certifications for non-compliance.

In the U.S., we are subject to various federal and state privacy and cybersecurity laws and regulations. The U.S. Gramm-Leach-Bliley Act (“GLBA”) requires financial institutions to explain their information sharing practices to their customers and to safeguard customer data. In some circumstances, we are subject to GLBA and we have privacy and information security obligations to our clients who are regulated by the GLBA. In certain circumstances, we are subject to the U.S. Health Insurance Portability and Accountability Act (“HIPAA”), which governs the use and disclosure of protected health information in healthcare treatment, payment and operations by covered entities and their business associates. We are also subject to the Federal Trade Commission Act which empowers the U.S. Federal Trade Commission (“FTC”) to prohibit unfair and deceptive practices, including those related to privacy and cybersecurity. In addition to the Federal Trade Commission Act, the FTC, along with the CFPB, is responsible for overseeing and enforcing the privacy and information security provisions over certain

Table of Contents

aspects of GLBA and the Fair Credit Reporting Act (“FCRA”), each of which is applicable to our businesses in certain circumstances. We also have obligations under various state privacy and cybersecurity laws, such as the California Consumer Privacy Act, which, among other things, give consumers more control over the personal information businesses hold about them.

In the European Union (“E.U.”) and the U.K., we are subject to the General Data Protection Regulation (“GDPR”), which imposes a comprehensive approach to personal data protection and includes penalties for non-compliance of up to the greater of 20 million Euro (or 17.5 million British Pound) or four percent of a company’s consolidated global revenue. There are numerous additional privacy laws and regulations that apply to our businesses around the world which also provide for significant penalties. Some of these data protection laws, including in the E.U., Argentina, Uruguay, Brazil, India, United Arab Emirates and China, impose requirements regarding data rights and security and either prohibit the international transfer of personal data or restrict such transfers absent lawfully recognized transfer mechanisms. Because we provide services in the financial services industry or are considered to be providing critical infrastructure to our clients additional obligations apply to us, including under the SOCI Act in Australia, the EBA Outsourcing Requirements and the Digital Operational Resilience Act in the E.U., and the CERT-In obligations in India.

Additional information about privacy and cybersecurity regulation applicable to our business can be found in the Risk Factors section of this report under the heading “Regulatory and Compliance Risks.”

Money Transmission and Payment Instrument Licensing and Regulations. We are subject to various U.S. federal, state and foreign laws and regulations governing money transmission and the issuance and sale of payment instruments, including some of our prepaid products. In the U.S., most states license money transmitters and issuers of payment instruments. Many states exercise authority over the operations of our services related to money transmission and payment instruments and, as part of this authority, subject us to periodic examinations. Many states require money transmitters, issuers of payment instruments and their agents to comply with federal and state anti-money laundering laws and regulations and often require the licensee to maintain certain levels of net worth.

Stablecoin Regulations. In 2025, the U.S. enacted the Guiding and Establishing National Innovation for U.S. Stablecoins Act (“GENIUS Act”), which provides a regulatory framework for payment stablecoins, and will become effective on the earlier of January 18, 2027, or 120 days after the issuance of final regulations implementing the GENIUS Act. Among other provisions, the GENIUS Act will subject payment stablecoin issuers to certain technical, disclosure, capital, liquidity and risk management requirements, require issuers to meet reserve backing and redemption standards, and subject issuers to regulatory supervision.

Credit Reporting and Debt Collections Regulations. TeleCheck, our check acceptance business, is subject to FCRA and various similar state laws. The collection business within our subsidiary TRS Recovery Services, Inc. (“TRS”) is subject to the U.S. federal Fair Debt Collection Practices Act and various similar state laws. TRS maintains licenses in a number of states in order to engage in collection in those states. TeleCheck and TRS are also subject to regulation, supervision and examination from the CFPB. In addition, several of our subsidiaries are subject to comparable local laws regarding collection activities and obtaining credit reports and the U.K. branch of our subsidiary FDR Limited, LLC also holds FCA permissions for debt collection activities.

Unfair Trade Practice Regulations. We and our clients are subject to various U.S. federal, state and foreign laws prohibiting unfair or deceptive trade practices. Various regulatory enforcement agencies, including the FTC and state attorneys general, have authority to take action against parties that engage in unfair or deceptive trade practices or violate other laws, rules and regulations. If we process payments for a merchant or other client in violation of laws, rules and regulations, we could be subject to enforcement actions and incur losses and liabilities that may impact our business.

Anti-Money Laundering, Anti-Bribery, and Sanctions Regulations. We are subject to anti-money laundering laws and regulations, including the U.S. Bank Secrecy Act (“BSA”). Among other things, the BSA requires money services businesses, such as money transmitters, issuers of money orders and official checks, and providers of prepaid access, to develop and implement anti-money laundering programs. Our U.S. MALPB and non-U.S. acquiring businesses are subject to anti-money laundering laws and regulations in the countries where they operate. Our Money Network Financial, LLC subsidiary provides prepaid access for various open loop prepaid programs for which it is the program manager and therefore must meet the requirements of the Financial Crimes Enforcement Network.

We are subject to the U.S. Foreign Corrupt Practices Act and similar anti-bribery and anti-corruption laws in the countries in which we operate. We are also subject to certain economic and trade sanctions programs that are administered by the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”), which prohibit or restrict transactions to or from, or dealings with, specified countries, governments, individuals and entities that are specially designated nationals of those countries, including narcotics traffickers and terrorists or terrorist organizations. Other entities may be subject to additional local sanctions requirements in other relevant jurisdictions.

Table of Contents

Similar anti-money laundering, counter terrorist financing and proceeds of crime laws apply to movements of currency and payments through electronic transactions and to dealings with persons specified in lists maintained by the country equivalents to OFAC lists in several other countries and require specific data retention obligations to be observed by intermediaries in the payment process. Our businesses in those jurisdictions are subject to those data retention obligations.

Communications Laws. We are subject to various federal and state laws that govern telephone calls and the issuance of text messages to clients and consumers in the U.S. as well as to regulations that impose requirements on marketing emails sent to U.S residents. Our foreign subsidiaries are subject to equivalent laws in applicable jurisdictions.

Indirect Regulatory Requirements. A number of our clients are subject to various regulations and compliance obligations that do not apply directly to us but impact the services that we provide to our clients. To remain competitive, we have invested, and expect to continue to invest, significant resources to develop and update our products and services to assist our clients to meet various compliance obligations. In addition, independent auditors annually review many of our operations to provide internal control evaluations for our clients and their auditors.

Human Capital

The Talent and Compensation Committee of our Board of Directors assists the Board of Directors in establishing our compensation philosophy and strategy and overseeing our human capital management strategy which includes maintaining a culture committed to attracting, developing and retaining top talent, fostering innovation, and promoting employee engagement, safety and well-being. As of December 31, 2025, we had over 38,000 employees worldwide.

Development and Retention

We are committed to creating a high-performance culture that consistently delivers excellence for our clients and long-term value for our shareholders while providing a workplace experience for our employees that values collaboration, innovation and diversity. Career development and internal mobility are important aspects of our value proposition for employees. We provide employees with numerous training and development opportunities, including through an e-learning platform specifically geared toward global technology employees; our Top Talent program, designed to accelerate the professional growth of our top talent across each of our global regions; our Leading Fiserv program, designed to develop critical leadership skills for frontline managers; our Vision to Results leadership program, focused on driving enterprise goals; and an online platform that provides global access to over 10,000 learning opportunities. Internal mobility is generally our preferred approach for filling open positions and fostering career advancement for our employees. To encourage internal mobility, we maintain an internal talent pipeline, increasing employee retention, job satisfaction and personal and professional growth opportunities.

We have adopted a pay-for-performance philosophy that is designed to recognize performance and reward achievement of our strategic business objectives and financial results. Total compensation consists of a competitive base pay and annual incentive opportunity typically delivered in a mix of cash and equity that is designed to promote retention and reward the attainment of defined performance goals. We are committed to providing fair pay to our employees regardless of gender, race, ethnicity or any other protected characteristic, and we regularly measure and evaluate employee compensation. In addition, throughout the year, we celebrate employee contributions and achievements through a peer-based global recognition program that enables recognition and financial rewards.

Employee Engagement

We value employee engagement and feedback. Throughout the year, we engage with our employees through events such as lunch-and-learns, quarterly all-hands meetings, town halls, leadership meetings and other forums. We encourage managers to meet regularly with their teams and encourage skip-level discussions.

To assess employee engagement, we periodically collect employee feedback through employee engagement surveys, including annual enterprise-wide surveys and issue-specific surveys. These surveys cover a variety of topics, such as engagement, well-being, client experience, employee experience, communication, teamwork, manager effectiveness and trust. In addition to assessing engagement, the survey results enable us to gain insight into employee perspectives and issues which we use to enhance processes, set priorities and respond to employee concerns. In 2025, 90% of our employees participated in our engagement survey.

Safety and Well-Being

We are committed to the safety of our workforce and maintain a global safety program that is designed to protect the safety and well-being of our employees in the workplace, minimize injury and accident frequency and severity, minimize loss to property, equipment and operational disruption, and enable greater employee satisfaction and productivity.

Table of Contents

We are also committed to providing comprehensive and competitive benefits to our employees that are responsive to their physical, financial, social and emotional needs. Our benefit offerings include a variety of medical and dental plan choices, mental health and counseling programs, caregiver support programs, enhanced family forming and planning resources, and paid time off. We seek to control the cost of health care benefits for our employees despite the increased cost of such benefits to the company. Investing in our employees in this way helps us retain top talent and demonstrates our commitment to our employees, our most important asset.

Available Information

Our website address is www.fiserv.com. We are not including the information provided on our website as a part of, or incorporating it by reference into, this Annual Report on Form 10-K. We make available free of charge (other than an investor’s own internet access charges) through our website our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to these reports, as soon as reasonably practicable after we electronically file such material with, or furnish such material to, the Securities and Exchange Commission.

You should carefully consider each of the risks described below, together with all of the other information contained in this Annual Report on Form 10-K, before making an investment decision with respect to our securities. If any of the following risks develop into actual events, our business, results of operations or financial condition could be materially and adversely affected, and you may lose all or part of your investment.

Competitive and Business Risks

We operate in a competitive business environment and may not be able to compete effectively.

The markets for our products and services are highly competitive from new and existing competitors. Our principal competitors include other vendors and providers of financial services technology and payment systems, data processing affiliates of large companies, processing centers owned or operated as user cooperatives, financial institutions, independent sales organizations (“ISOs”), independent software vendors, payments companies and payment network operators. Our competitors vary in size and in the scope and breadth of the services they offer. Many of our larger existing and potential clients have historically developed their key applications in-house. As a result, we may compete against our existing or potential clients’ in-house capabilities. In addition, we expect that the markets in which we compete will continue to attract new technologies and well-funded competitors, including large technology, telecommunication, media and other companies not historically in the financial services and payments industries, start-ups and international providers of products and services similar to ours. In addition, participants in the financial services, payments and technology industries may merge, create joint ventures or engage in other business combinations, alliances and consolidations that may strengthen their existing products and services or create new products and services that compete with ours. We cannot provide any assurance that we will be able to compete successfully against current or future competitors or that competitive pressures faced by us in the markets in which we operate will not materially and adversely affect our business, results of operations and financial condition.

If we fail to keep pace with technological change, including as a result of artificial intelligence, we could lose clients or have trouble attracting new clients.

The markets for our products and services are characterized by constant and rapid technological change, evolving industry standards, frequent introduction of new products and services, and increasing client expectations. Our ability to respond timely to these changes, including by enhancing our current products and services and developing and introducing new products and services, will significantly affect our future success. In addition, competitors and other third parties may incorporate artificial intelligence into products and offerings more quickly or more successfully than we do, which could impair our ability to compete effectively and adversely affect our results of operations. Furthermore, the success of certain of our products and services rely, in part, on financial institutions, business partners and other third parties promoting the use of or distributing our products and services. If we are unsuccessful in developing, marketing and selling products or services that gain market acceptance, or if third parties insufficiently promote or distribute our products and services, it would likely have a material adverse effect on our ability to retain existing clients, to attract new ones and to grow profitably.

We use artificial intelligence in our business, and challenges with properly managing its use could result in legal liability or reputational harm.

We believe that data, and the insights enabled by data, can be used to create or enhance the products and services that we offer to our clients. As a result, we are using, and expect to continue to expand our use of, artificial intelligence and machine learning in our product development processes, services and operations. The use of artificial intelligence technologies carries inherent

Table of Contents

risks, and there can be no assurance that our use of artificial intelligence will enhance our products or services or achieve any improvements in innovation or efficiency. If the content, analyses or recommendations that artificial intelligence applications assist in producing are or are alleged to be inaccurate, deficient or biased, our business, financial condition and results of operations may be adversely affected. Furthermore, our services that integrate third-party artificial intelligence models may rely on certain safeguards implemented by the third-party providers of the underlying artificial intelligence models, including those related to the accuracy, bias and other variables of the data, and these safeguards may be insufficient. Legislation and regulations governing the development or use of artificial intelligence and automated-decision making have been implemented or are under consideration in the U.S. at the state and local level, as well as internationally. Such legislation and regulations may impose obligations related to our development, offering, and use of artificial intelligence, particularly those use cases that are deemed by the law to be “high risk”, and expose us to increased risk of regulatory enforcement and litigation. As a result, our ability to use artificial intelligence and machine learning may be constrained by current or future laws, regulatory or self-regulatory requirements.

The One Fiserv action plan may not generate the benefits that we anticipate.

In 2025, we announced a strategic plan, referred to as the One Fiserv action plan, that focuses on: operating with a client-first mindset to win new enterprise clients and grow average revenue per client; building the pre-eminent small business operating platform through Clover; creating differentiated, innovative platforms in finance and commerce, including embedded finance and stablecoin; delivering operational excellence enabled by artificial intelligence; and employing disciplined capital allocation for the long-term. To successfully execute the plan, we must implement operational, technological and cultural changes across our organization, which may be difficult to do. In addition, although we have planned for a certain level of expense in implementing the plan, there are factors beyond our control that could cause the total amount or the timing of the expenses we may incur to be different than anticipated. As a result, the actual benefits of the plan may be less significant than anticipated. Furthermore, we may not be able to achieve expected benefits of the plan on our anticipated timeline or at all.

If we are unable to renew contracts on favorable terms or if contracts are terminated prematurely, we could lose clients and our results of operations and financial condition may be adversely affected.

Failure to achieve favorable renewals of client contracts could negatively impact our business. At the end of the contract term, clients have the opportunity to renegotiate their contracts with us or to consider whether to engage one or more of our competitors to provide products and services or to perform the services in-house. Some of our competitors may offer more attractive prices, features or other services that we do not offer, and some clients may desire to perform the services themselves. Larger clients may be able to seek lower prices from us when they renew or extend a contract or the client’s business has significant volume changes. In addition, larger clients may reduce the services we provide if they decide to move services in-house. Further, our small merchant business clients may seek reduced f

Enterprise Risk Management

At the core of our business, we host, collect, process, use and retain significant amounts of financial, personal and other sensitive data across our own technology environment and the third-party information systems of our vendors, service providers and partners. In order to keep this data secure, we maintain an enterprise risk management (“ERM”) program designed to systematically identify and manage risk including risk from cybersecurity threats. The risk committee of the board of directors oversees our ERM program and it is reviewed annually by both the risk and audit committees of the board of directors. The risk committee also monitors and reports to the board regarding issues arising with respect to the risk governance structure and performance of the risk management function. The board, as a whole and through its committees, regularly engages with the Chief Risk Officer, management and outside advisors to identify, assess and manage risks of the company and to ensure the risk management function has the appropriate resources and authority to fulfill its responsibilities. An executive risk committee, comprised of senior leaders of our lines of business and corporate functions, provides executive level accountability for the ERM program.

On an ongoing basis, we identify, categorize, assess, monitor and respond to business risks. We consider the various ways in which risks may affect our business by measuring the impact of those risks against a consistent set of criteria, which include the potential impact to our operations, financial performance, clients, technology, reputation, business strategy and regulatory environment. The risk committee of the board of directors reviews and approves a list of top enterprise risks and the risk appetite relating to such risks. Among the top risks included in our ERM program is cybersecurity risk. Response plans are developed, tracked and implemented for residual risks that are above the acceptable tolerance level.

Cybersecurity Risk

Management’s Role in Cybersecurity

Our global cybersecurity services team is responsible for assessing our technology environment, identifying emerging cybersecurity threats and evolving cybersecurity threat capabilities, and implementing business processes and technical defenses to safeguard our technology environment and services. Our management has established a cybersecurity and technology risk committee focused on managing cybersecurity and technology risk and implementing cybersecurity and technology plans, strategies and objectives. The committee is chaired by the Deputy Chief Information Security Officer, who reports to our Co-President through our Chief Information Security Officer (“CISO”), and is comprised of senior business, cybersecurity, and technology leaders responsible for delivering our products and services. Our cybersecurity program is designed to enable us to detect and respond to cybersecurity incidents, continually improve the effectiveness of our cybersecurity controls, and dynamically respond to the evolving threat landscape.

We operate a cybersecurity operations center that continuously monitors our environment for cyber events, suspicious activity or unusual behaviors, and responds to minimize operational impact. We use layered security technologies, controls and modern analytics to detect, prevent and respond to threats. Our global cybersecurity services team gathers intelligence from public and private sources about threats, adversary campaigns and vulnerabilities. The global cybersecurity services team combines this external intelligence with our internal intelligence and analytics to assess risk and develop strategies that reduce exposure and improve response.

We maintain a global cybersecurity policy and supporting standards which incorporate recognized industry standards and best practices from the National Institute of Standards and Technology as well as various industry security requirements.

Our employees play a vital role in protecting our and our clients’ data. We provide annual, mandatory training for all of our employees regarding cybersecurity threats to enable our employees to address cybersecurity threats and to communicate our evolving information security policies, standards, processes and practices. We also maintain a third-party risk management program to identify, assess, mitigate and monitor risks associated with third parties’ software and services that we utilize.

Our CISO has served in various senior roles in information technology and information security, in both the public and private sector, for over three decades. Similarly, the other members of our global cybersecurity services team have a broad range of cybersecurity training and experience in both the public, including military and law enforcement, and private sectors and maintain various certifications in relevant subjects.

Board Oversight

The board of directors maintains primary oversight of the company’s strategic, operational and financial risks, including cybersecurity risks. The risk committee of the board of directors assists the board in its oversight of such risks and is primarily responsible for oversight of cybersecurity risks. The risk committee regularly reviews and discusses with management the current cybersecurity threat landscape, emerging trends and developments, and the company’s guidelines, policies and processes for monitoring, managing, and mitigating cybersecurity risks.

The board and the risk committee receive regular presentations and reports from management as well as outside experts on cybersecurity risks, which address a wide range of topics including recent developments, evolving standards, vulnerability assessments, third-party and independent reviews, the threat environment, technology trends and information security considerations arising with respect to our peers and third parties. On an annual basis, the board and the risk committee discuss our approach to cybersecurity risk management with our Chief Risk Officer, Chief Compliance Officer and Chief Information Security Officer, among others. At each regular board meeting, the risk committee reviews and reports to the board on key cybersecurity risks. The board and the risk committee receive prompt and timely information regarding any cybersecurity incident that meets established reporting thresholds, as well as ongoing updates regarding any such incident until it has been addressed.

Impact of Cybersecurity Threats

Our results of operations and financial condition have not been materially affected by cybersecurity threats or incidents to date. However, to assess, identify, and manage material risks from cybersecurity threats, including as a result of previous cybersecurity incidents, we have invested and expect to continue to invest significant resources, including maintaining cybersecurity insurance coverage, to sustain and enhance our information security and controls or to investigate and mitigate security vulnerabilities. As a result, cybersecurity threats and other technological risks involving our systems have materially affected our business strategy and processes. Although we believe that we maintain a robust program of information security and controls and that none of the cybersecurity incidents that we have encountered to date have materially affected us, we

Table of Contents

cannot be certain that the security measures and procedures we have in place to detect security incidents and protect sensitive data will be successful or sufficient to counter all current and emerging risks and threats. The impact of a material cybersecurity incident involving our systems and data, or those of our clients, partners or vendors, could have a material adverse effect on our business strategy, results of operations and financial condition.

Additional information on the impact of cybersecurity threats applicable to our business can be found in the Risk Factors section of this report under the heading “Operational and Security Risks”.

At December 31, 2025, we owned 16 and leased 120 properties globally. Our real estate strategy includes developing centralized campus environments in strategic locations, including in Florida, Georgia, Nebraska, New Jersey, Wisconsin and Dublin, Ireland. These locations are used for operational, data center, sales, management and administrative purposes. As a normal part of our business operations, including in connection with the integration of companies that we acquire, we regularly review our real estate portfolio. We may choose to acquire or dispose of properties in order to maintain a real estate footprint designed to maximize collaboration, innovation and communication in ways that enable us to best serve our clients and to create more opportunities for professional growth and development for our associates.

One Fiserv Action Plan

In the third quarter of 2025, we launched the One Fiserv action plan designed to prioritize and enhance client focus across five strategic pillars.

Market risk refers to the risk that a change in the level of one or more market prices, interest rates, inflation, currency exchange rates, indices, correlations or other market factors, such as liquidity, will result in losses for a certain financial instrument or group of financial instruments. Our senior management actively monitors certain market risks to which we are exposed, primarily from fluctuations in interest rates and foreign currency exchange rates. In order to limit our exposure to these risks, we may enter into derivative instruments with creditworthy institutions to hedge against changing interest rates and foreign currency rate fluctuations. We currently utilize forward exchange contracts, fixed-to-fixed cross-currency rate swap contracts and other non-derivative hedging instruments to manage risk.

Interest Rate Risk

In addition to existing cash and cash equivalents balances and cash provided by operating activities, we use a combination of fixed- and variable-rate debt instruments to finance our operations. We are exposed to interest rate risk on certain of these debt obligations. We had fixed- and variable-rate debt, excluding finance leases and other financing obligations, with varying maturities for an aggregate carrying amount of $24.9 billion and $2.1 billion, respectively, at December 31, 2025. Our fixed-rate debt at December 31, 2025 primarily consisted of fixed-rate senior notes with a fair value of $24.3 billion, based on matrix pricing which considers readily observable inputs of comparable securities. The potential change in fair value of our fixed-rate senior notes from a hypothetical 1% change in market interest rates would not alone impact any decisions to repurchase our outstanding fixed-rate debt instruments before their maturity. Our variable-rate debt at December 31, 2025 primarily consisted of outstanding U.S. dollar and Euro commercial paper and borrowings on our variable rate foreign lines of credit. Based on our outstanding debt balances and interest rates at December 31, 2025, a hypothetical 1% increase in market interest rates related to our variable-rate debt would increase annual interest expense by approximately $21 million. This sensitivity analysis assumes the outstanding debt balances at December 31, 2025 and the change in market interest rates is applicable for an entire year.

Table of Contents

In connection with processing electronic payments transactions, funds received from subscribers are invested into short-term, highly liquid investments from the time we collect the funds until payments are made to the applicable recipients. Fluctuations in market interest rates affect the interest-related income that we earn on these investments. We also earn interest on intermediary settlement cash balances received from agents, payment networks, bank partners, merchants or direct consumers that we hold on behalf of merchants until the funding becomes due to the merchants or payees. Subscriber funds and intermediary settlement cash balances earning interest averaged $3.6 billion during the year ended December 31, 2025. The interest earned on subscriber funds and intermediary settlement cash is recorded as a component of total revenue in the consolidated statements of income. During the year ended December 31, 2025, a hypothetical 1% decrease in market interest rates would decrease the annual interest-related income by approximately $36 million. This sensitivity analysis uses the average subscriber fund and intermediary settlement cash balances during the year ended December 31, 2025 and assumes the change in market interest rates is applicable for an entire year.

Our risk with regard to interest rate fluctuations is largely mitigated by the offsetting impacts associated with our variable-rate debt and interest earning liquid investments associated with subscriber funds and intermediary settlement cash.

Foreign Currency Risk

We conduct business globally and are exposed to foreign currency risk from changes in the value of underlying monetary assets and liabilities of our non-U.S. dollar-denominated foreign investments and foreign currency transactions. We manage the exposure to these risks through the use of foreign currency forward exchange contracts, fixed-to-fixed cross-currency rate swap contracts and non-derivative net investment hedges. Translation gains and losses from non-U.S. subsidiaries are generally reflected as a component of accumulated other comprehensive loss within shareholders’ equity on the consolidated balance sheets. For subsidiaries located in highly inflationary economies, primarily Argentina, the financial statements are remeasured into U.S. dollars, and the foreign currency gains and losses from the remeasurement of monetary assets and liabilities are reflected in the consolidated statements of income, rather than in shareholders’ equity. In April 2025, the Argentine government announced economic policy changes, including the removal of certain currency controls, resulting in a significant devaluation of the Argentine Peso. Additionally, the Argentina Peso experienced significant volatility during 2025 due to the recent economic landscape in Argentina. The remeasurement of monetary assets and liabilities in highly inflationary economies, including Argentina, resulted in foreign currency exchange losses of $158 million and $98 million during the years ended December 31, 2025 and 2024, respectively, which is included within other expense, net in the consolidated statements of income. Gains and losses from foreign currency transactions, included within operating expenses in the consolidated statements of income, were not significant during the years ended December 31, 2025 and 2024. We also have exposure to risks related to currency devaluation in certain countries, which may negatively impact our international operating results if there is a prolonged devaluation of local currencies relative to the U.S. dollar or if the economic conditions in these countries decline.

Our exposure to foreign currency exchange risks generally arise from our international operations to the extent they are conducted in local currency. Approximately 16% of our total revenue was generated internationally in 2025. The major currencies to which our revenues are exposed are the Argentine Peso, Brazilian Real, British Pound, Euro and Indian Rupee.

A strengthening or weakening of the U.S. dollar, relative to the currencies in which our income is denominated, by 10% would not have a material impact on our reported pre-tax income for the years ended December 31, 2025 and 2024.

We maintain forward exchange contracts, designated as cash flow hedges, to hedge foreign currency exposure to the Indian Rupee. At December 31, 2025, the notional amount of these derivatives was $323 million, with a fair value liability of $11 million. In addition, we maintain fixed-to-fixed cross-currency rate swap contracts to hedge a portion of our net investment in certain subsidiaries whose functional currencies are in the Euro, Singapore Dollar and Canadian Dollar. At December 31, 2025, aggregate notional fixed-to-fixed cross-currency rate swaps of 940 million Euros, 828 million Singapore Dollars and 405 million Canadian Dollars were designated as net investment hedges. We also designated certain of our Euro- and British Pound-denominated senior notes and Euro commercial paper notes as net investment hedges to hedge a portion of our net investment in certain subsidiaries whose functional currencies are the Euro and British Pound.

*(b)*Management Report on Internal Control Over Financial Reporting

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) under the Securities Exchange Act of 1934. Our 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.

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 risk that controls may become inadequate because of changes in conditions.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2025. 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 management’s assessment, our management believes that, as of December 31, 2025, our internal control over financial reporting was effective based on those criteria.

Our independent registered public accounting firm has issued their attestation report on our internal control over financial reporting. The report is included below under the heading “Report of Independent Registered Public Accounting Firm on Internal Control Over Financial Reporting.”

*(c)*Changes in Internal Control Over Financial Reporting

There was no change in internal control over financial reporting that occurred during the three months ended December 31, 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Fiserv, Inc.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Fiserv, Inc. and subsidiaries (the “Company”) as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2025, of the Company and our report dated February 19, 2026, expressed an unqualified opinion on those financial statements.

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 Annual 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 included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and 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.
