Global Economy and Inflation

Since 2022 and during the year ended December 31, 2023, the global economy has experienced high inflation, increased interest rates, and pressures on gross domestic product. While we believe our business is resilient and can generally weather unusually high levels of inflation, inflationary pressures have had some impact on our 2023 financial performance. Specifically, inflation had impacted our interchange costs associated with the Biller segment.

PART I

ITEM 1. BUSINESS

General

ACI develops, markets, installs, and supports a broad line of software products and solutions primarily focused on facilitating real-time digital payments. ACI’s enterprise payments capabilities target any channel, any network, and any payment type and our solutions empower customers to regain control, choice, and flexibility in today’s complex payments environment, get to market more quickly, and reduce operational costs.

ACI's solutions and services are used globally by banks, intermediaries, merchants, and billers, such as third-party digital payment processors, payment associations, switch interchanges, and a wide range of transaction-generating endpoints, including automated teller machines (“ATM”), merchant point-of-sale (“POS”) terminals, bank branches, mobile phones, tablets, corporations, and internet commerce sites. The authentication, authorization, switching, settlement, fraud-checking, and reconciliation of digital payments is a complex activity due to the large number of locations and variety of sources from which transactions can be generated, the large number of participants in the market, high transaction volumes, geographically dispersed networks, differing types of authorization, and varied reporting requirements. These activities are typically performed online and are conducted 24 hours a day, seven days a week.

ACI combines a global perspective with local presence to tailor digital payment solutions for our customers. We believe that we have one of the most diverse and robust digital payment solution portfolios in the industry with application software spanning the entire payments value chain. We also believe that our financial performance has been attributable to our ability to design and deliver quality products and solutions coupled with our ability to identify and successfully complete and integrate strategic acquisitions.

ACI is a Delaware corporation incorporated in November 1993 under the name ACI Holding, Inc. We are largely the successor to Applied Communications, Inc. and Applied Communications Inc. Limited, acquired from Tandem Computers Incorporated on December 31, 1993. On July 24, 2007, we changed our corporate name from “Transaction Systems Architects, Inc.” to “ACI Worldwide, Inc.” We have been marketing our products and services under the ACI Worldwide brand since 1993 and have gained significant market recognition under this brand name.

Fiscal 2022 Divestiture

Corporate Online Banking Solutions

On September 1, 2022, we sold our corporate online banking solutions related assets and liabilities to One Equity Partners for $100.0 million, and a net working capital adjustment. The sale included employees and customer contracts as well as technology assets and intellectual property.

Target Markets

ACI’s comprehensive digital payment solutions serve three key markets:

Banks

ACI provides payment solutions to large and mid-size banks globally for both retail banking, digital, and other payment services. Our solutions transform banks’ complex payment environments to speed time to market, reduce costs, and deliver a consistent experience to customers across channels while enabling them to prevent and rapidly react to fraudulent activity. In addition, we enable banks to meet the requirements of different real-time payment schemes and to quickly create differentiated products to meet consumer, business, and merchant demands.

ACI’s payment solutions support intermediaries, such as processors, networks, payment service providers (“PSPs”), and new financial technology ("fintech") entrants. We offer these customers scalable solutions that strategically position them to innovate and achieve growth and cost efficiency, while protecting them against fraud. Our solutions also allow new entrants in the digital marketplace to access innovative payment schemes, such as the U.S. FedNow and RTP from The Clearing House, the U.K. Faster Payments New Access Model, Singapore FAST, India Unified Payments Interface ("UPI"), the Payments Network Malaysia ("PayNet"), Real-time Retail Payments Platform ("RPP"), and others.

Merchants

ACI’s support of merchants globally includes Tier 1 and Tier 2 merchants, online-only merchants and the PSPs, independent selling organizations (“ISOs”), value-added resellers (“VARs”), and acquirers who service them. These customers operate in a variety of verticals, including general merchandise, grocery, hospitality, dining, transportation, and others. Our solutions provide merchants with a secure, omni-channel payments platform that gives them independence from third-party payment providers. We also offer secure solutions to online-only merchants that provide consumers with a convenient and seamless way to shop.

Billers

Within the biller segment, ACI provides electronic bill presentment and payment (“EBPP”) services to companies operating in the consumer finance, insurance, healthcare, higher education, utility, government, mortgage, subscription providers, and telecommunications categories. Our solutions enable these customers to support a wide range of payment options and provide a convenient consumer payments experience that drives consumer loyalty and increases revenue.

ACI Speedpay® is an integrated suite of digital billing, payment, disbursement, and communication services that lowers the cost of presenting and accepting bill payments while delivering industry-leading security.

On Premises, On Demand, or Hybrid Software Delivery Options

Our software solutions are offered to our customers through either a traditional term software license arrangement where the software is installed and operated on the customer premises or in a cloud environment, through an on-demand arrangement where the solution is maintained and delivered through the public cloud or ACI's private cloud via our global data centers, or a combination of the two based upon their unique needs. Solutions delivered through ACI’s on-demand cloud are available in either a single-tenant environment, known as a Software-as-a-Service (“SaaS”) offering, or in a multi-tenant environment, known as a Platform-as-a-Service (“PaaS”) offering. Pricing and payment terms depend on which solutions the customer requires and their transaction volumes. Generally, customers are required to commit to a minimum contract of five years, or three years in the case of certain acquired SaaS and PaaS contracts.

Partnerships and Industry Participation

We have two major types of third-party product partners: 1) technology partners, or industry leaders with whom we work closely that drive key industry trends and mandates, and 2) business partners, where we either embed the partners’ technology in ACI products, host the partners’ software in ACI’s cloud as a part of our cloud offerings, or jointly market solutions that include the products of the other company.

Technology partners help us add value to our solutions and stay abreast of current market conditions and industry developments such as standards. In addition, ACI has membership in or participates in the relevant committees of several industry associations, such as the International Organization for Standardization (“ISO”), Accredited Standards Committee ("ASC") X9, ATM Industry Association ("ATMIA"), Financial Services, Nexo Standards, U.K. Cards Association, U.S. Payments Forum, and the PCI Security Standards Council. These partnerships provide direction as it relates to the specifications that are used by the card schemes, real-time payment standards, and, in some cases, hardware vendors. These organizations typically look to ACI as a source of knowledge and experience to be shared in conjunction with creating and enhancing their standards. The benefit to ACI is having the opportunity to influence these standards with concepts and ideas that will benefit the market, our customers, and ACI.

ACI also holds important positions at different payment advisory leader groups worldwide, including advisory board membership with the Faster Payments Council in the U.S., global advisory board membership with the Merchant Risk Council ("MRC"), and a key stakeholder membership with the European Payments Council ("EPC").

Table of Contents

Business partner relationships extend our product portfolio, improve our ability to get our solutions to market, and enhance our ability to deliver market-leading solutions. We share revenues with these business partners based on several factors related to overall value contribution in the delivery of the joint solution or payment type. The agreements with business partners include referral, resale, traditional original equipment manufacturer (“OEM”) relationships, and transaction fee-based payment-enablement partnerships. These agreements generally grant ACI the right to create an integrated solution that we host or distribute, or provide ACI access to established payment networks or capabilities. The agreements are generally worldwide in scope and have a term of several years.

We have alliances with our technology partners Microsoft Corporation, Amazon, Google, HPE, IBM, and Oracle USA, Inc. (“Oracle”), whose industry-leading hardware, software, and cloud-based infrastructure services are utilized by and in delivery of ACI’s products. These partnerships allow us to understand developments in the partners’ technology and to utilize their expertise in topics like sizing, scalability, and performance testing.

Services

We offer our customers a wide range of professional services, including consultation, analysis, design, development, implementation, integration, testing, and project management. Our service professionals generally perform the majority of the work associated with implementing and integrating our software solutions. In addition, we work with a limited number of systems integration and services partners such as Accenture, LLC, Cognizant Technology Solutions Corporation, and Stanchion Payments Solution for staff augmentation and coordinated co-prime delivery where appropriate.

Product support services are available to customers after a solution has been installed and are based on the relevant product support category. An extensive team of support analysts are available to assist customers.

In addition, ACI education services with instructor-led courses include both theory and practical sessions to allow students to work though real business scenarios and put their newly learned skills to use. This hands-on approach ensures that the knowledge is retained, and the student is more productive upon their return to the workplace. Some training topics are further supplemented by self-paced eLearning, available to students on demand to support their skills journey. ACI’s education courses provide students with knowledge at all levels to enhance and improve their understanding of ACI products. ACI also provides further, more in-depth technical courses that allow students to use practical labs to enhance what they have learned in the classroom. The ACI trainers' ability to understand customers' systems means ACI may also provide tailored course materials for individual customers. Depending on the products purchased, training may be conducted at a dedicated education facility at one of ACI’s offices, online, on demand, or at the customer site.

Customer Support

ACI provides our customers with product support that is available 24 hours a day, seven days a week. We offer our customers two support options:

Standard Customer Support. After implementation completion, we provide maintenance services to customers for a monthly product support fee. Maintenance services include:

•New product releases (major, minor and patches) for active products

•24-hour hotline for priority one (“P1”) problem resolutions

•Access to our online support portal (eSupport)

•Vendor-required mandates and updates

•Product documentation

•Hardware operating system compatibility

•User group membership

Table of Contents

Premium Customer Support. Under the premium customer support option, referred to as the Premium Customer Support Program and available at additional cost, customers are provided support beyond the standard offering. The services available may differ by product and are defined in the customer contract.

We periodically provide new product releases, which often contain minor product enhancements, that are typically provided at no additional fee for customers under standard customer support agreements. Agreements with our customers permit us to charge for substantial product enhancements that are not provided as part of the standard or premium customer support agreement.

Competition

The digital payments market is highly competitive and subject to rapid change. Competitive factors affecting the market for our solutions, products, and services include product features, price, availability of customer support, ease of implementation, product and company reputation, and a commitment to continued investment in research and development.

Our competitors vary by solution, geography, and market segment. Generally, our most significant competition comes from in-house information technology departments of existing and potential customers, as well as third-party digital payment processors (some of whom are our customers). Many of these companies are significantly larger than us and have significantly greater financial, technical, and marketing resources.

Key competitors by solution area include the following:

The third-party software competitors for ACI’s Issuing, Acquiring, and Real-Time Payments solutions include Fidelity National Information Service, Inc. ("FIS"), Finastra, Fiserv, Inc.

Primary digital payment processing competitors in this area include global entities such as Atos Origin S.A., Fiserv, Mastercard, SiNSYS, and VISA, as well as regional or country-specific processors.

Third-party software and service competitors include Adyen, Cybersource (VISA Acceptance Solutions), Fiserv, Ingenico Group, NCR, Square, Inc., Tender Retail Inc., VeriFone Systems, Inc., Worldpay Inc. (FIS), and Worldline.

We are also competing in some areas with the traditional orchestration layer providers such as IXOpay, Payoneer, Nuvei, and Spreedly.

Principal competitors for our ACI Fraud Management solution are Accertify (American Express), BAE Systems, Cybersource (VISA), Fair Isaac Corporation, Featurespace, Feedzai, FIS, Fiserv, Forter, Kount, NCR, NICE LTD, and SAS Institute, Inc., as well as dozens of smaller companies focused on niches of this segment such as device identification and anti-money laundering.

(FIS), as well as smaller vertical-specific providers.

Research and Development

Our product development efforts focus on new products while continuing to increase the functionality of existing products. To ensure we are building for the market, we facilitate user group meetings to help us determine our product and solution strategy, development plans, and aspects of customer support. The user groups are generally organized geographically or by product lines. We believe that the timely development of new applications and enhancements is essential to maintaining our competitive position in the market.

Table of Contents

During the development of new products and solutions, we work closely with our customers and industry leaders to determine requirements. We work with device manufacturers, such as Diebold, NCR, and Wincor-Nixdorf, to ensure compatibility with the latest ATM technology. We work with network vendors, such as Mastercard, SWIFT, and VISA, to ensure compliance with new regulations or processing mandates. We work with computer hardware and software manufacturers, such as HPE, IBM, Microsoft Corporation, and Oracle, to ensure compatibility with new operating system releases and generations of hardware. Customers often provide additional information on requirements and serve as beta-test partners.

We have a continuous process to encourage and capture innovative product ideas. Such ideas include features, as well as entirely new products or service offerings. A proof of concept (“POC”) may be conducted to validate the idea. If determined to be viable, the innovation is scheduled into a product roadmap for development and release.

Customers

We provide software products and solutions to our banks, intermediary, and merchants customers worldwide. Our biller products and solutions are sold in the United States. As of December 31, 2023, we serve more than 6,000 organizations, including all 10 of the top 10 banks worldwide, as measured by asset size, and 80,000+ merchants directly and through payment service providers, and we have customers in 95+ countries on six continents. No single customer accounted for more than 10% of our consolidated revenues for the years ended December 31, 2023, 2022, and 2021. No customer accounted for more than 10% of the Company’s consolidated receivables balance as of December 31, 2023. One customer accounted for 10.1% of the Company's consolidated receivables balance as of December 31, 2022.

Selling and Implementation

Our products are sold and supported directly and through distribution networks covering three geographic regions – the Americas, Europe/Middle East/Africa ("EMEA") and Asia Pacific. Our primary method of distribution is direct sales by employees assigned to specific target customer segments. We have sales and services personnel in offices throughout the United States. Outside of the United States, our international subsidiaries sell, support, and service our products and solutions in their local countries. Our broad geographic footprint allows us to leverage the business and technical expertise of a global workforce.

We generate a majority of our sales leads through existing relationships with vendors, direct marketing programs, customers and prospects, or through referrals.

We use distributors and referral partners to supplement our direct sales force in countries where it is more efficient and economical to do so. ACI’s distributors, resellers, and system integration partners are enabled to provide supplemental or complete product implementation and customization services directly to our customers or in a joint delivery model.

We distribute the products of other vendors where they complement our existing product lines. We are typically responsible for the sales and marketing of the vendors' products, and agreements with these vendors generally provide for revenue sharing based on relative responsibilities.

Proprietary Rights and Licenses

We rely on a combination of trade secret and copyright laws, license agreements, contractual provisions, and confidentiality agreements to protect our proprietary rights. We distribute our software products under software license agreements that typically grant customers nonexclusive licenses to use our products. Use of our software products is usually restricted to designated computers, specified locations and/or specified capacity, and is subject to terms and conditions prohibiting unauthorized reproduction or transfer of our software products. We also seek to protect the source code of our software as a trade secret and as a copyrighted work. Despite these precautions, there can be no assurance that misappropriation of our software products and technology will not occur.

In addition to our own products, we distribute, or act as a sales agent for, software developed by third parties. However, we typically are not involved in the development process used by these third parties. Our rights to those third-party products and the associated intellectual property rights are limited by the terms of the contractual agreement between us and the respective third party.

Although we believe that our owned and licensed intellectual property rights do not infringe upon the proprietary rights of third parties, there can be no assurance that third parties will not assert infringement claims against us. Further, there can be no assurance that intellectual property protection will be available for our products in all foreign countries.

Government Regulation

Certain of our solutions are subject to federal, state, and foreign regulations and requirements.

Oversight by Banking Regulators. As a provider of payment services to banks and intermediaries, we are subject to regulatory oversight and examination by the Federal Financial Institutions Examination Council (“FFIEC”), an interagency body of the Federal Deposit Insurance Corporation, the Office of the Comptroller of the Currency, the Board of Governors of the Federal Reserve System, the National Credit Union Administration and various state regulatory authorities as part of the Multi-Region Data Processing Servicer Program (“MDPS”). The MDPS program includes technology suppliers who provide mission critical applications for a large number of financial institutions that are regulated by multiple regulatory agencies. Periodic information technology examination assessments are performed using FFIEC interagency guidelines to identify potential risks that could adversely affect serviced financial institutions, determine compliance with applicable laws and regulations that affect the services provided to financial institutions and ensure the services we provide to financial institutions do not create systemic risk to the banking system or impact the safe and sound operation of the financial institutions we serve. In addition, independent auditors annually review several of our operations to provide reports on internal controls for our clients’ auditors and regulators. We are also subject to review under state and foreign laws and rules that regulate many of the same activities that are described above, including electronic data processing and back-office services for financial institutions and the use of consumer information.

Money Transfer. ACI Payments, Inc., our EBPP affiliate, is registered as a Money Services Business. Accordingly, we are subject to the USA Patriot Act and reporting requirements of the Bank Secrecy Act and United States ("U.S.") Treasury Regulations. These businesses may also be subject to certain state and local licensing requirements. The Financial Crimes Enforcement Network (“FinCEN”), state attorneys general, and other agencies have enforcement responsibility over laws relating to money laundering, currency transmission, and licensing. In addition, most states have enacted statutes that require entities engaged in money transmission to register as a money transmitter with that jurisdiction’s banking department. We have implemented policies, procedures, and internal controls that are designed to comply with all applicable anti-money laundering laws and regulations. ACI has also implemented policies, procedures, and internal controls that are designed to comply with the regulations and economic sanctions programs administered by the U.S. Treasury’s Office of Foreign Assets Control (“OFAC”), which enforces economic and trade sanctions against targeted foreign countries, entities and individuals based on external threats to the U.S. foreign policy, national security, or economy; by other governments; or by global or regional multilateral organizations, such as the United Nations Security Council and the European Union as applicable.

Human Capital

As of December 31, 2023, we had 3,212 employees worldwide, with 1,427 employees in the Americas, 890 employees in Europe, the Middle East, and Africa ("EMEA"), and 895 employees in Asia Pacific. ACI emphasizes a diverse and inclusive workplace, with approximately 30 sites in over 40 countries. Globally, 35% of our employees are women. We are committed to ensuring employees feel safe and respected, regardless of race, color, age, gender, disability, minority, sexual orientation, or any other protected class. Employees have the ability to challenge themselves and continue to grow through various assignments, projects, and development programs. We strive to offer competitive salaries and benefits to all employees, and we continuously monitor salary ranges in our market areas.

Retention

Our voluntary regrettable turnover, or our turnover of high performers, through December 31, 2023 was 8%, which compares favorably to industry turnover rates. We are pleased with our retention and will continue to employ strategies to retain and engage our global employees.

ITEM 1A. RISK FACTORS

We operate in a rapidly changing technological and economic environment that presents numerous risks. Many of these risks are beyond our control and are driven by factors that often cannot be predicted. The following discussion highlights some of these risks.

Risks Related to Our Business and Operations

The markets in which we compete are rapidly changing and highly competitive, and we may not be able to compete effectively.

The markets in which we compete are characterized by rapid change, frequent introduction of new products and services, evolving technologies and industry standards, intense competition, and increasing client expectations. We may not be successful in developing, marketing, or selling new products and services that meet these demands or achieve market acceptance. We must anticipate and respond to these changes in order to remain competitive within our relevant markets. There is no assurance that we will be able to maintain our current market share or customer base. We face intense competition in our businesses and we expect competition to remain intense in the future. We have many competitors that are significantly larger than us and have significantly greater financial, technical and marketing resources, have well-established relationships with our current or potential customers, advertise aggressively or beat us to the market with new products and services. In addition, some of our clients have chosen to develop key products in-house. As a result, we may compete against our existing and potential clients' in-house capabilities. Additionally, we expect that the markets in which we compete will continue to attract new competitors and new technologies. Increased competition in our markets could lead to price reductions, reduced profits, or loss of market share.

Table of Contents

To compete successfully, we need to maintain a successful research and development effort. If we fail to enhance our current products and develop new products in response to changes in technology and industry standards, bring product enhancements or new product developments to market quickly enough, or accurately predict future changes in our customers’ needs and our competitors develop new technologies or products, our products could become less competitive or obsolete. In addition, the success of certain of our products and services rely, in part, on financial institutions, corporate, and other third parties to promote the use of our products and services by their customers. If we are unsuccessful in offering products or services that gain market acceptance and compete effectively, or if third parties insufficiently promote 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.

If we experience business interruptions or failure of our information technology and communication systems, the availability of our products and services could be interrupted which could adversely affect our reputation, business and financial condition.

Our ability to provide reliable service in a number of our businesses depends on the efficient and uninterrupted operation of our data centers, information technology and communication systems, and those of our external service providers. As we continue to grow our private and public cloud offerings, our dependency on the continuing operation and availability of these systems increases. Our systems and data centers, and those of our external service providers, could be exposed to damage or interruption from fire, natural disasters, constraints within our workforce due to pandemics such as outbreaks of COVID-19, power loss, telecommunications failure, unauthorized entry and computer viruses. Although we have taken steps to prevent system failures and we have installed back-up systems and procedures to prevent or reduce disruption, such steps may not be sufficient to prevent an interruption of services and our disaster recovery planning may not account for all eventualities. Further, our property and business interruption insurance may not be adequate to compensate us for all losses or failures that may occur.

An operational failure or outage in any of these systems, or damage to or destruction of these systems, which causes disruptions in our services, could result in loss of customers, damage to customer relationships, reduced revenues and profits, refunds of customer charges and damage to our brand and reputation and may require us to incur substantial additional expense to repair or replace damaged equipment and recover data loss caused by the interruption. Any one or more of the foregoing occurrences could have a material adverse effect on our reputation, business, financial condition, cash flows and results of operations.

If our security measures are breached or become infected with a computer virus, or if our services are subject to attacks that degrade or deny the ability of users to access our products or services, our business may be harmed by disrupting delivery of services and damaging our reputation.

As part of our business, we electronically receive, process, store, and transmit sensitive business information of our customers. Unauthorized access to our computer systems or databases could result in the theft or publication of confidential information or the deletion or modification of records or could otherwise cause interruptions in our operations. These concerns about security are increased when we transmit information over the Internet. Security breaches in connection with the delivery of our products and services, including products and services utilizing the Internet, or well-publicized security breaches, and the trend toward broad consumer and general public notification of such incidents, could significantly harm our business, financial condition, cash flows and/or results of operations. We cannot be certain that advances in criminal capabilities, discovery of new vulnerabilities, attempts to exploit vulnerabilities in our systems, data thefts, physical system or network break-ins or inappropriate access, or other developments will not compromise or breach the technology protecting our networks and confidential information. Computer viruses have also been distributed and have rapidly spread over the Internet. Computer viruses could infiltrate our systems, disrupting our delivery of services and making our applications unavailable. Any inability to prevent security breaches or computer viruses could also cause existing customers to lose confidence in our systems and terminate their agreements with us, and could inhibit our ability to attract new customers.

Failure to attract and retain senior management personnel and skilled technical employees could harm our ability to grow.

Our senior management team has significant experience in the financial services industry. The loss of this leadership could have an adverse effect on our business, operating results and financial condition. Further, the loss of this leadership may have an adverse impact on senior management’s ability to provide effective oversight and strategic direction for all key functions within our company, which could impact our future business, operating results and financial condition.

Our future success also depends upon our ability to attract and retain highly-skilled technical personnel. Because the development of our solutions and services requires knowledge of computer hardware, operating system software, system management software, and application software, our technical personnel must be proficient in a number of disciplines. Competition for such technical personnel is intense, and our failure to hire and retain talented personnel could have a material adverse effect on our business, operating results and financial condition.

Table of Contents

Our future growth will also require sales and marketing, financial and administrative personnel to develop and support new solutions and services, to enhance and support current solutions and services and to expand operational and financial systems. There can be no assurance that we will be able to attract and retain the necessary personnel to accomplish our growth strategies and we may experience constraints that could adversely affect our ability to satisfy client demand in a timely fashion.

Our ability to maintain compliance with applicable laws, rules and regulations and to manage and monitor the risks facing our business relies upon the ability to maintain skilled compliance, security, risk and audit professionals. Competition for such skillsets is intense, and our failure to hire and retain talented personnel could have an adverse effect on our internal control environment and impact our operating results.

During the global COVID-19 pandemic, a significant portion of our workforce worked mostly in a remote environment. While our employees have begun to transition back to the office, this remote environment has continued after the pandemic for some of our workforce in part or in full, and could impact the quality of our corporate culture. Failure to attract, hire, develop, motivate and retain highly qualified and diverse employee talent, or to maintain a corporate culture that fosters innovation, creativity, and teamwork could harm our overall business and results of operations.

If we engage in acquisitions, strategic partnerships or significant investments in new business, we will be exposed to risks which could materially adversely affect our business.

As part of our business strategy, we anticipate that we may acquire new products and services or enhance existing products and services through acquisitions of other companies, product lines, technologies and personnel, or through investments in, or strategic partnerships with, other companies. Any acquisition, investment or partnership, is subject to a number of risks. Such risks include the diversion of management time and resources, disruption of our ongoing business, potential overpayment for the acquired company or assets, dilution to existing stockholders if our common stock is issued in consideration for an acquisition or investment, incurring or assuming indebtedness or other liabilities in connection with an acquisition which may increase our interest expense and leverage significantly, lack of familiarity with new markets, and difficulties in supporting new product lines.

Further, even if we successfully complete acquisitions, we may encounter issues not discovered during our due diligence process, including product or service quality issues, intellectual property issues and legal contingencies, the internal control environment of the acquired entity may not be consistent with our standards and may require significant time and resources to improve and we may impair relationships with employees and customers as a result of migrating a business or product line to a new owner. We may also face challenges in integrating any acquired business. These challenges may include eliminating redundant operations, facilities and systems, coordinating management and personnel, retaining key employees, customers and business partners, managing different corporate cultures, and achieving cost reductions and cross-selling opportunities. There can be no assurance that we will be able to fully integrate all aspects of acquired businesses successfully, realize synergies expected to result from the acquisition, advance our business strategy or fully realize the potential benefits of bringing the businesses together, and the process of integrating these acquisitions may further disrupt our business and divert our resources.

Our failure to successfully manage acquisitions or investments, or successfully integrate acquisitions could have a material adverse effect on our business, financial condition, cash flows and/or results of operations. Correspondingly, our expectations related to the benefits related to our recent acquisitions, prior acquisitions or any other future acquisition or investment could be inaccurate.

Failure to successfully complete divestitures or other restructuring activities could negatively affect our operations.

From time to time, we may divest of all or a portion of certain businesses. Divestitures involve risk, including, potential increased expense associated with the divestitures, and potential issues with the acquirers, customers or suppliers of the divested business, or products. Occasionally, we may wind down certain business activities and perform other organizational restructuring projects in an effort to reduce costs and streamline operations. For example, we divested our corporate online banking solutions related assets and liabilities to One Equity Partners on September 1, 2022. Divestiture activities involve risks as they may divert management's attention from our core businesses, increase expenses on a short‑term basis and lead to potential issues with employees or customers. If we do not complete these activities in a timely manner, or do not realize anticipated cost savings, synergies and efficiencies, business disruption occurs during or following such activities, or we incur unanticipated charges, this may negatively impact our business, financial condition, operating results, and cash flows.

We may experience difficulties implementing our strategy, and the strategy could prove unsuccessful in growing our business.

Our strategy focuses on investments in real-time payments, large sophisticated global merchants, and fast-growing emerging markets. Successfully implementing our strategy may present organizational and infrastructure challenges, and we may not be able to fully implement or realize the intended benefits of our strategy. Moving to a new business strategy may result in a loss of established efficiency, which may have a negative impact on our business. As we adjust, we also may need to bring on additional talent, which could prove difficult in a competitive job market, especially as remote working continues. The increased focus on opportunities for strategic mergers and acquisitions and research and development could result in financial difficulties and may not always be fruitful. We may also face an increased amount of competition as we attempt to expand and grow our business, which may negatively impact our financial results. In order for us to be successful as we enter and invest in emerging markets, these markets must continue to grow. However, this growth depends on a variety of factors that we are not always able to predict.

To the extent that we convert some or all of our on-premise licenses from a fixed-term to a subscription model, our future financial results will be affected by the frequency at which our customers adopt our subscription model, which carries with it certain risks.

Our on-premise licenses currently have a five-year fixed term model. In the future, we may transition some or all of these licenses to a subscription model. A transition to a subscription model would reflect a significant shift from a fixed-term license. In addition, a subscription model presents a number of risks to us including the following:

•arrangements entered into on a subscription basis generally delay the timing of revenue recognition and can require the incurrence of up-front costs, which may be significant;

•subscription models make it difficult to rapidly increase revenues through additional bookings in any period, as revenues are recognized ratably over the subscription period;

•customers in a subscription arrangement may elect not to renew their contract upon expiration or they may attempt to renegotiate pricing or other contractual terms at the point of (or prior to) renewal on terms that are less favorable to us; and

•there is no assurance that our customers will broadly accept a subscription model for our on-premise licenses.

Certain anti-takeover provisions contained in our charter and under Delaware law could hinder a takeover attempt.

We are subject to the provisions of Section 203 of the General Corporation Law of the State of Delaware prohibiting, under some circumstances, publicly held Delaware corporations from engaging in business combinations with some stockholders for a specified period of time without the approval of the holders of substantially all of our outstanding voting stock. Such provisions could delay or impede the removal of incumbent directors and could make more difficult a merger, tender offer, or proxy contest involving us, even if such events could be beneficial, in the short term, to the interests of our stockholders. In addition, such provisions could limit the price that some investors might be willing to pay in the future for shares of our common stock. Our certificate of incorporation and bylaws contain provisions relating to the limitation of liability and indemnification of our directors and officers, dividing our board of directors into three classes of directors serving three-year terms and providing that our stockholders can take action only at a duly called annual or special meeting of stockholders.

Risks Related to Our Customers

Certain payment funding methods expose us to the credit and/or operating risk of our clients.

When we process an automated clearing house or ATM network payment transaction for certain clients, we occasionally transfer funds from our settlement account to the intended destination account before we receive funds from a client’s source account. The vast majority of these occurrences are resolved quickly through normal processes. However, if they are not resolved and we are then unable to reverse the transaction that sent funds to the intended destination, a shortfall in our settlement account will be created. Although we have legal recourse against our clients for the amount of the shortfall, timing of recovery may be delayed by litigation or the amount of any recovery may be less than the shortfall. In either case, we would have to fund the shortfall in our settlement account from our corporate funds.

Potential customers may be reluctant to switch to a new vendor, which may adversely affect our growth, both in the United States and internationally.

For banks, intermediaries, and other potential customers of our products, switching from one vendor of core financial services software (or from an internally developed legacy system) to a new vendor is a significant endeavor. Many potential customers believe switching vendors involves too many potential disadvantages such as disruption of business operations, loss of accustomed functionality, and increased costs (including conversion and transition costs). As a result, potential customers may resist change. We seek to overcome this resistance through value enhancing strategies such as a defined conversion/migration process, continued investment in the enhanced functionality of our software and system integration expertise. However, there can be no assurance that our strategies for overcoming potential customers’ reluctance to change vendors will be successful, and this resistance may adversely affect our growth, both in the United States and internationally.

Risks Related to Our Intellectual Property

We may be unable to protect our intellectual property and technology.

To protect our proprietary rights in our intellectual property, we rely on a combination of contractual provisions, including customer licenses that restrict use of our products, confidentiality agreements and procedures, and trade secret and copyright laws. Despite such efforts, we may not be able to adequately protect our proprietary rights, or our competitors may independently develop similar technology, duplicate products, or design around any rights we believe to be proprietary. This may be particularly true in countries other than the United States because some foreign laws do not protect proprietary rights to the same extent as certain laws of the United States. Any failure or inability to protect our proprietary rights could materially adversely affect our business.

We also use a limited amount of software licensed by its authors or other third parties under so-called “open source” licenses and may continue to use such software in the future. Some of these licenses contain requirements that we make available source code for modifications or derivative works we create based upon the open source software, and that we license such modifications or derivative works under the terms of a particular open source license or other license granting third parties certain rights of further use. By the terms of certain open source licenses, we could be required to release the source code of our proprietary software if we combine our proprietary software with open source software in a certain manner. Additionally, the terms of many open source licenses have not been interpreted by United States or other courts, and there is a risk that these licenses could be construed in a manner that could impose unanticipated conditions or restrictions on our ability to commercialize our solutions. In addition to risks related to license requirements, usage of certain open source software can lead to greater risks than use of third-party commercial software, as open source licensors generally do not provide warranties or controls on origin of the software.

Our exposure to risks associated with the use of intellectual property may be increased for third-party products distributed by us or as a result of acquisitions since we have a lower level of visibility, if any, into the development process with respect to such third-party products and acquired technology or the care taken to safeguard against infringement risks.

We may be subject to increasing litigation over our intellectual property rights.

There has been a substantial amount of litigation in the software industry regarding intellectual property rights. Third parties have in the past, and may in the future, assert claims or initiate litigation related to exclusive patent, copyright, trademark or other intellectual property rights to business processes, technologies and related standards that are relevant to us and our customers. These assertions have increased over time as a result of the general increase in patent claims assertions, particularly in the United States. Because of the existence of a large number of patents in the electronic commerce field, the secrecy of some pending patents and the rapid issuance of new patents, it is not economical or even possible to determine in advance whether a product or any of its components infringes or will infringe on the patent rights of others. Any claim against us, with or without merit, could be time-consuming, result in costly litigation, cause product delivery delays, require us to enter into royalty or licensing agreements or pay amounts in settlement, or require us to develop alternative non-infringing technology.

Table of Contents

We anticipate that software product developers and providers of electronic commerce solutions could increasingly be subject to infringement claims, and third parties may claim that our present and future products infringe upon their intellectual property rights. Third parties may also claim, and we are aware that at least two parties have claimed on several occasions, that our customers’ use of a business process method which utilizes our products in conjunction with other products infringe on the third-party’s intellectual property rights. These third-party claims could lead to indemnification claims against us by our customers. Claims against our customers related to our products, whether or not meritorious, could harm our reputation and reduce demand for our products. Where indemnification claims are made by customers, resistance even to unmeritorious claims could damage the customer relationship. A successful claim by a third-party of intellectual property infringement by us or one of our customers could compel us to enter into costly royalty or license agreements, pay significant damages, or stop selling certain products and incur additional costs to develop alternative non-infringing technology. Royalty or licensing agreements, if required, may not be available on terms acceptable to us or at all, which could adversely affect our business.

We are engaged in offshore software development activities, which may not be successful and which may put our intellectual property at risk.

As part of our globalization strategy and to optimize available research and development resources, we utilize our Irish subsidiary to serve as the focal point for certain international product development and commercialization efforts. This subsidiary oversees remote software development operations in Romania and elsewhere, as well as manages certain of our intellectual property rights. In addition, we manage certain offshore development activities in India. While our experience to date with our offshore development centers has been positive, there is no assurance that this will continue. Specifically, there are a number of risks associated with this activity, including but not limited to the following:

•communications and information flow may be less efficient and accurate as a consequence of the time, distance and language differences between our primary development organization and the foreign based activities, resulting in delays in development or errors in the software developed;

•in addition to the risk of misappropriation of intellectual property from departing personnel, there is a general risk of the potential for misappropriation of our intellectual property that might not be readily discoverable;

•the quality of the development efforts undertaken offshore may not meet our requirements because of language, cultural and experiential differences, resulting in potential product errors and/or delays;

•potential disruption from the involvement of the United States in political and military conflicts around the world; and

•currency exchange rates could fluctuate and adversely impact the cost advantages intended from maintaining these facilities.

Risks Related to Our International Operations

There are a number of risks associated with our international operations that could have a material impact on our operations and financial condition.

We derive a significant portion of our revenues from international operations and anticipate continuing to do so. As a result, we are subject to risks of conducting international operations. One of the principal risks associated with international operations is potentially adverse movements of foreign currency exchange rates. Revenues and profit generated by international operations will increase or decrease compared to prior periods as a result of changes in foreign currency exchange rates. Our exposures resulting from fluctuations in foreign currency exchange rates may change over time as our business evolves and could have an adverse impact on our financial condition, cash flows and/or results of operations. We have not entered into any derivative instruments or hedging contracts to reduce exposure to adverse foreign currency changes.

Other potential risks include difficulties associated with staffing and management, competing with more established companies in international markets, reliance on independent distributors, longer payment cycles, potentially unfavorable changes to foreign tax rules, unfavorable trade treaties or tariffs, compliance with foreign regulatory requirements, effects of a variety of foreign laws and regulations, including restrictions on access to personal information, reduced protection of intellectual property rights, variability of foreign economic conditions, governmental currency controls, difficulties in enforcing our contracts in foreign jurisdictions, and general economic and political conditions in the countries where we sell our products and services. Some of our products may contain encrypted technology, the export of which is regulated by the United States government. Changes in U.S. and other applicable export laws and regulations restricting the export of software or encryption technology could result in delays or reductions in our shipments of products internationally. There can be no assurance that we will be able to successfully address these challenges.

Political, military, and other international developments can undermine bilateral cooperation in key policy areas, significantly disrupt trade, and otherwise adversely affect economic conditions.

Table of Contents

Recent events in eastern Europe and the Middle East present challenges and risks to us, and no assurances can be given that current or future developments would not have a material adverse effect on our business, results of operations and financial condition.

The crises in eastern Europe and the Middle East continues to be a challenge to global companies, including us. We currently have an office with 48 employees in Russia, a customer in Russia, and customers located in the Middle East. The U.S. and other global governments have placed restrictions on how companies may transact with, and provide services or solutions to, parties in these regions, particularly Russia, Belarus and restricted areas in Ukraine. We are currently in the process of closing our office in Russia and terminating our agreement with our customer in Russia, and do not expect to incur material expenses in connection with such activities. We believe the closure and termination will help us comply with our obligations under the various requirements in the U.S. and around the world. While it is difficult to estimate the impact on our business and financial position of our augmented operations with respect to businesses in Russia, Belarus, the restricted areas in Ukraine, and in the Middle East and the current or future sanctions, such changes could have adverse impacts on us in future periods. In addition, no assurances can be given that additional developments in the impacted regions, and responses thereto from the U.S. and other global governments, would not have a material adverse effect on our business, results of operations and financial condition.

Risks Related to Our Products and Services

Global economic conditions could reduce the demand for our products and services or otherwise adversely impact our cash flows, operating results and financial condition.

For the foreseeable future, we expect to derive most of our revenue from products and services we provide to the banking and financial services industries. Given this focus, we are exposed to global economic conditions, and adverse economic trends that may accelerate the timing, or increase the impact of, risks to our financial performance.

The global electronic payments industry and the banking and financial services industries depend heavily upon the overall levels of consumer, business and government spending. Adverse economic conditions such as those caused by the global economic downturn, the Russia-Ukraine conflict, the COVID-19 pandemic, and the potential for disruptions in these industries as well as the general software sector could result in a decrease in consumers’ use of banking services and financial service providers resulting in significant decreases in the demand for our products and services which could adversely affect our business and operating results. A lessening demand in either the overall economy, the banking and financial services industry or the software sector could also result in the implementation by banks and related financial service providers of cost reduction measures or reduced capital spending resulting in longer sales cycles, deferral or delay of purchase commitments for our products and increased price competition which could lead to a material decrease in our future revenues and earnings.

Our business may be negatively affected by domestic and global economic and credit conditions.

Our business is sensitive to the strength of domestic and global economic and credit conditions, particularly as they affect, either directly or indirectly, the banking and financial services industries. Economic and credit conditions are influenced by a number of factors, including political conditions, consumer confidence, unemployment levels, interest rates, tax rates, commodity prices, and government actions to stimulate economic growth. The imposition or threat of protectionist trade policies or import or export tariffs, global and regional market conditions and spending trends in the financial, retail and hospitality industries, new tax legislation across multiple jurisdictions, modified or new global or regional trade agreements, uncertainty over further potential changes in Eurozone participation and fluctuations in oil and commodity prices, among other things, have created a challenging and unpredictable environment in which to market our products and services across our different geographies and industries. A negative or unpredictable economic climate could create uncertainty or financial pressures that impact the ability or willingness of our customers to make capital expenditures, thereby affecting their decision to purchase or roll out our products or services or to pay accounts receivable owed to us. Additionally, if customers respond to a negative or unpredictable economic climate by consolidation, it could reduce our base of potential customers.

If our products and services fail to comply with legislation, government regulations, and industry standards to which our customers are subject, it could result in a loss of customers and decreased revenue.

Legislation, governmental regulation, and industry standards affect how our business is conducted, and in some cases, could subject us to the possibility of future lawsuits arising from our products and services. Globally, legislation, governmental regulation and industry standards may directly or indirectly impact our current and prospective customers’ activities, as well as their expectations and needs in relation to our products and services. For example, our products are affected by VISA, Mastercard and other major payment brand electronic payment standards that are generally updated twice annually. Beyond this, our products are affected by PCI Security Standards. As a provider of electronic data processing to financial institutions, we must comply with FFIEC regulations and are subject to FFIEC examinations.

Table of Contents

Legislation and regulation related to credit availability, data usage, privacy, or other related regulatory developments could have an adverse effect on our customers or us. Laws and regulations concerning the handling of personal information are expanding and becoming more complex. Our failure, or perceived failure, to comply with these and other laws and regulations could adversely affect our business and harm our reputation.

Our software products may contain undetected errors or other defects, which could damage our reputation with customers, decrease profitability, and expose us to liability.

Our software products are complex. Software may contain bugs or defects that could unexpectedly interfere with the operation of the software products when first introduced or as new versions are released. Additionally, errors could occur during our provision of services, including processing services such as our bill payment services and other services delivered through public or private cloud. Software defects or service errors may result in the loss of, or delay in, market acceptance of our products and services and a corresponding loss of sales or revenues.

Customers depend upon our products and services for mission-critical applications, and product defects or service errors may hurt our reputation with customers. In addition, software product defects or errors could subject us to liability for damages, performance and warranty claims, and fines or penalties from governmental authorities, which could be material.

Risks Related to Legal, Regulatory, and Tax Matters

If we fail to comply with the complex regulations applicable to our payments business, we could be subject to liability or our revenues may be reduced.

ACI Payments, Inc. is licensed as a money transmitter in those states where such licensure is required. These licenses require us to demonstrate and maintain certain levels of net worth and liquidity, require us to file periodic reports and subject us to inspections by state regulatory agencies. In addition, our payment business is generally subject to federal regulation in the United States, including anti-money laundering regulations and certain restrictions on transactions to or from certain individuals or entities. The complexity of these regulations will continue to increase our cost of doing business. Any violations of these laws may also result in civil or criminal penalties against us and our officers or the prohibition against us providing money transmitter services in particular jurisdictions. We could also be forced to change our business practices or be required to obtain additional licenses or regulatory approvals that could cause us to incur substantial costs.

In addition, our customers must ensure that our services comply with the government regulations, including the EU GDPR, and industry standards that apply to their businesses. Federal, state, foreign or industry authorities could adopt laws, rules, or regulations affecting our customers’ businesses that could lead to increased operating costs that may lead to reduced market acceptance. In addition, action by regulatory authorities relating to credit availability, data usage, privacy, or other related regulatory developments could have an adverse effect on our customers and, therefore, could have a material adverse effect on our business, financial condition, and results of operations.

Our business could be harmed if we fail to comply with privacy and cybersecurity laws and regulations imposed on providers of services to financial institutions.

As a provider of services to financial institutions, we may be bound by the same limitations on disclosure of the information we receive from our customers as apply to the financial institutions themselves. If we fail to comply with applicable laws and regulations, including the EU GDPR, CCPA, and other laws, we could be exposed to regulatory investigations and actions, lawsuits for breach of contract or to governmental or consumer claims, our customer relationships and reputation could be harmed, and we could be inhibited in our ability to obtain new customers. Compliance with these and new laws could involve substantial expenses and divert resources from other initiatives and projects. More restrictive privacy and cybersecurity laws adopted in the future could have an adverse impact on our business.

U.S. and other banking agencies have adopted or proposed enhanced cyber risk management standards that would apply to us and our financial institution clients and that would address cyber risk governance and management, management of internal and external dependencies, and incident response, cyber resilience, and situational awareness. Several states in the U.S. have adopted or proposed new privacy and cybersecurity laws targeting these issues. Legislation and regulations on cybersecurity, data privacy and data localization may compel us to need to modify our systems, invest in new systems or alter our business practices or our policies on data governance and privacy. These actions could significantly increase our operational costs.

Table of Contents

Our risk management and information security programs are subject to oversight and periodic reviews by governmental agencies that regulate our business. In the event an examination of our information security and risk management functions results in adverse findings, such findings could be made public or communicated to our regulated financial institution customers, which could have a material adverse effect on us.

We are subject to consent orders and other compliance agreements (the “Consent Orders and Compliance Agreements”) entered into in connection with the settlement of state and federal regulators’ investigations. Failure to comply with the Consent Orders and Compliance Agreements could result in further, and more significant, enforcement actions against us.

We are required to conduct our operations in compliance with the Consent Orders and Compliance Agreements. While we have complied with the Consent Orders and Compliance Agreements, and have implemented processes by which we believe we will maintain compliance with the Consent Orders and Compliance Agreements going forward, we cannot be certain that we will maintain compliance with the Consent Orders and Compliance Agreements in all instances. In the event that we are deemed to be non-compliant with the terms of the Consent Orders and/or Compliance Agreements, the state and/or federal regulators have the authority to subject us to additional, and potentially more significant, corrective actions and could seek to initiate further enforcement actions against us, including seeking civil money penalties. Any failure by us to comply with the terms of the Consent Orders and Compliance Agreements or additional actions could adversely affect our business, financial condition and results of operations. In addition, our competitors may not be subject to similar actions, which could limit our ability to compete effectively.

We may face exposure to unknown tax liabilities, which could adversely affect our financial condition, cash flows and/or results of operations.

We are subject to income and non-income based taxes in the United States and in various foreign jurisdictions. Significant judgment is required in determining our worldwide income tax liabilities and other tax liabilities. We believe that our tax-saving strategies comply with applicable tax law. If the governing tax authorities have a different interpretation of the applicable law and successfully challenge any of our tax positions, our financial condition, cash flows and/or results of operations could be adversely affected.

Our U.S. companies are the subject of an examination by several state tax departments. Some of our foreign subsidiaries are currently the subject of a tax examination by the local taxing authorities. Other foreign subsidiaries could face challenges from various foreign tax authorities. It is not certain that the local authorities will accept our tax positions. We believe our tax positions comply with applicable tax law and intend to vigorously defend our positions. However, differing positions on certain issues could be upheld by foreign tax authorities, which could adversely affect our financial condition and/or results of operations.

Changes in tax laws and regulations could adversely affect our results of operations and cash flows from operations.

Our operations are subject to tax by federal, state, local, and international taxing jurisdictions. Changes in tax laws or their interpretations in our significant tax jurisdictions could materially increase the amount of taxes we owe, thereby negatively impacting our results of operations as well as our cash flows from operations. Additionally, future tax laws, regulations or guidance from the Internal Revenue Service, the Securities and Exchange Commission, or the Financial Accounting Standards Board could cause us to adjust current estimates in future periods, which could impact our earnings and have an adverse effect on our results of operations and cash flow.

The U.S. Congress, the Organization for Economic Co-operation and Development (the “OECD”) and other government agencies in jurisdictions in which we do business remain focused on the taxation of multinational corporations. The OECD, which represents a coalition of member countries, including the U.S., is contemplating changes to numerous longstanding tax principles, including ensuring all companies pay a 15% global minimum tax through the enactment of Pillar Two Model Rules (“Pillar Two”) and expanding taxing rights of market countries. Pillar Two is expected to be applicable to us beginning January 1, 2024; however, the timing of implementation of Pillar Two rules at the local country level is uncertain. The specific Pillar Two measures requiring adoption will vary among participating countries. Significant uncertainty remains regarding the implementation and impact of these initiatives, which could adversely affect our business or financial results.

Furthermore, our implementation of new practices and processes designed to comply with changing tax laws and regulations could require us to make substantial changes to our business practices, allocate additional resources, and increase our costs, which could negatively affect our business, results of operations, and financial condition.

Risks Related to Our Industry

Consolidations and failures in the financial services industry may adversely impact the number of customers and our revenues in the future.

Mergers, acquisitions, and personnel changes at key financial services organizations have the potential to adversely affect our business, financial condition, cash flows, and results of operations. Our business is concentrated in the financial services industry, making us susceptible to consolidation in, or contraction of, the number of participating institutions within that industry.

Our stock price may be volatile.

No assurance can be given that operating results will not vary from quarter to quarter, and past performance may not accurately predict future performance. Any fluctuations in quarterly operating results may result in volatility in our stock price. Our stock price may also be volatile, in part, due to external factors such as speculation regarding potential transactions, announcements by third parties or competitors, inherent volatility in the technology sector, variability in demand from our existing customers, failure to meet the expectations of market analysts, the level of our operating expenses, changing market conditions in the software industry, and the global economic downturn. In addition, the financial markets have experienced significant price and volume fluctuations that have particularly affected the stock prices of many technology companies and financial services companies, and these fluctuations sometimes are unrelated to the operating performance of these companies. Broad market fluctuations, as well as industry-specific and general economic conditions may adversely affect the market price of our common stock.

Risks Related to Our Financial Performance

Our future profitability depends on demand for our products.

Our revenue and profitability depend on the overall demand for our products and services. A significant portion of our total revenues result from licensing our Issuing and Acquiring solutions, including our BASE24 product line and providing related services and maintenance. Any reduction in demand for, or increase in competition with respect to, our Issuing and Acquiring solutions could have a material adverse effect on our financial condition, cash flows and/or results of operations.

Failure to obtain renewals of customer contracts or obtain such renewals on favorable terms could adversely affect our results of operations and financial condition.

Failure to achieve favorable renewals of customer contracts could negatively impact our business. Our contracts with our customers generally run for a period of five years, or three years in the case of certain acquired SaaS and PaaS contracts. At the end of the contract term, customers have the opportunity to renegotiate their contracts with us and to consider whether to engage one of our competitors to provide products and services. Failure to achieve high renewal rates on commercially favorable terms could adversely affect our results of operations and financial condition.

The delay or cancellation of a customer project or inaccurate project completion estimates may adversely affect our operating results and financial performance.

Any unanticipated delays in a customer project, changes in customer requirements or priorities during the project implementation period, or a customer’s decision to cancel a project, may adversely impact our operating results and financial performance. In addition, during the project implementation period, we perform ongoing estimates of the progress being made on complex and difficult projects and documenting this progress is subject to potential inaccuracies. Changes in project completion estimates are heavily dependent on the accuracy of our initial project completion estimates and our ability to evaluate project profits and losses. Any inaccuracies or changes in estimates resulting from changes in customer requirements, delays or inaccurate initial project completion estimates may result in increased project costs and adversely impact our operating results and financial performance.

Our balance sheet includes significant amounts of goodwill and intangible assets. The impairment of a significant portion of these assets could negatively affect our financial results.

Our balance sheet includes goodwill and intangible assets that represent a significant portion of our total assets at December 31, 2023. On at least an annual basis, we assess whether there have been impairments in the carrying value of goodwill and intangible assets. If the carrying value of the asset is determined to be impaired, then it is written down to fair value by a charge to operating earnings. An impairment of a significant portion of goodwill or intangible assets could materially negatively affect our results of operations.

Table of Contents

Management’s backlog estimate may not be accurate and may not generate the predicted revenues.

Estimates of future financial results are inherently unreliable. Our backlog estimates require substantial judgment and are based on a number of assumptions, including management’s current assessment of customer and third-party contracts that exist as of the date the estimates are made, as well as revenues from assumed contract renewals, to the extent that we believe that recognition of the related revenue will occur within the corresponding backlog period. A number of factors could result in actual revenues being less than the amounts reflected in backlog. Our customers or third-party partners may attempt to renegotiate or terminate their contracts for a number of reasons, including mergers, changes in their financial condition, or general changes in economic conditions within their industries or geographic locations, or we may experience delays in the development or delivery of products or services specified in customer contracts. Actual renewal rates and amounts may differ from historical experience used to estimate backlog amounts. Changes in foreign currency exchange rates may also impact the amount of revenue actually recognized in future periods. Accordingly, there can be no assurance that contracts included in backlog will actually generate the specified revenues or that the actual revenues will be generated within a 12-month or 60-month period. Additionally, because backlog estimates are operating metrics, the estimates are not required to be subject to the same level of internal review or controls as a U.S. generally accepted accounting principles (“GAAP”) financial measure.

Our revenue and earnings are highly cyclical, our quarterly results fluctuate significantly, and we have revenue-generating transactions concentrated in the final weeks of a quarter which may prevent accurate forecasting of our financial results and cause our stock price to decline.

Our revenue and earnings are highly cyclical causing significant quarterly fluctuations in our financial results. Revenue and operating results are usually strongest during the third and fourth fiscal quarters ending September 30 and December 31, primarily due to the sales and budgetary cycles of our customers. We experience lower revenues, and possible operating losses, in the first and second quarters ending March 31 and June 30. Our financial results may also fluctuate from quarter to quarter and year to year due to a variety of factors, including changes in product sales mix that affect average selling prices, and the timing of customer renewals (any of which may impact the pattern of revenue recognition).

In addition, large portions of our customer contracts are executed in the final weeks of each quarter. Before these contracts are executed, we create and rely on forecasted revenues for planning, modeling and earnings guidance. Forecasts, however, are only estimates and actual results may vary for a particular quarter or longer periods of time. Consequently, significant discrepancies between actual and forecasted results could limit our ability to plan, budget or provide accurate guidance, which could adversely affect our stock price. Any publicly-stated revenue or earnings projections are subject to this risk.

Risks Related to Financing

Our outstanding debt contains restrictions and other financial covenants that limit our flexibility in operating our business.

Our credit facility and the indenture governing our 5.750% Senior Notes due 2026 (“2026 Notes”) contain customary affirmative and negative covenants for debt of these types that limit our ability to engage in specified types of transactions. If an event of default occurs, the lenders, trustee, or holders of the 2026 Notes will be entitled to take various actions, including, but not limited to, demanding payment for all amounts outstanding. If adverse global economic conditions persist or worsen, we could experience decreased revenues from our operations attributable to reduced demand for our products and services and as a result, we could fail to satisfy the financial and other restrictive covenants to which we are subject under our existing debt, resulting in an event of default. If we are unable to cure the default or obtain a waiver, we will not be able to access our credit facility and there can be no assurance that we would be able to obtain alternative financing. See Note 4, Debt, to our Notes to Consolidated Financial Statements in Part IV, Item 15 of this Form 10-K for additional information.

Our existing levels of debt and debt service requirements may adversely affect our financial condition or operational flexibility and prevent us from fulfilling our obligations under our outstanding indebtedness.

Our level of debt could have adverse consequences for our business, financial condition, operating results and operational flexibility, including the following: (i) the debt level may cause us to have difficulty borrowing money in the future for working capital, capital expenditures, acquisitions or other purposes; (ii) our debt level may limit operational flexibility and our ability to pursue business opportunities and implement certain business strategies; (iii) we use a large portion of our operating cash flow to pay principal and interest on our credit facility and the 2026 Notes, which reduces the amount of money available to finance operations, acquisitions and other business activities; (iv) we have a higher level of debt than some of our competitors or potential competitors, which may cause a competitive disadvantage and may reduce flexibility in responding to changing business and economic conditions, including increased competition and vulnerability to general adverse economic and industry conditions; (v) some of our debt has a variable rate of interest, which exposes us to the risk of increased interest rates; (vi) there are significant maturities on our debt that we may not be able to fulfill or that may be refinanced at higher rates; and (vii) if we fail to satisfy our obligations under our outstanding debt or fail to comply with the financial or other restrictive covenants

Table of Contents

required under our credit facility and the 2026 Notes, an event of default could result that could cause all of our debt to become due and payable and could permit the lenders under our credit facility to foreclose on the assets securing such debt.

Despite our current levels of debt, we may still incur substantially more debt, including secured debt, and similar liabilities,

which would increase the risks described in these risk factors relating to indebtedness.

Although the agreements governing our credit facility and our 2026 Notes include restrictions on our ability to incur additional debt, those agreements do not prohibit us from incurring additional debt or pursuing other financing arrangements. As a result, the amount of additional debt and other obligations that we could incur could be substantial. Accordingly, to the extent permitted under our credit agreement or indenture, we could incur significant additional debt, liabilities or similar obligations in the future. In addition, if we form or acquire any subsidiaries in the future, those subsidiaries also could incur debt or similar liabilities. If new debt or similar liabilities are added to our current debt levels, the related risks that we now face could increase.

We may, from time to time, seek to opportunistically refinance, amend, reprice and/or otherwise replace any of our debt, obtain additional debt financing or enter into other financing arrangements, reduce or extend our debt, lower our interest payments or the cost of capital available to us under certain types of financing arrangements, or otherwise seek to improve our financial position or the terms of our debt or other financing agreements. These actions may include open market debt repurchases, negotiated repurchases, or other repayments, redemptions or retirements of our debt or other financing arrangements. The amount of debt that may be borrowed or issued, refinanced, and/or repurchased, repaid, redeemed or otherwise retired, if any, will depend on market conditions, trading levels of our debt, our cash position, compliance with our debt covenants and other considerations. Any such actions could impact our financial condition or results of operations.

General Risk Factors

Our business and operating results could be adversely affected by events outside of our control, including natural disasters, wars and outbreaks of disease or other adverse public health developments.

We may be impacted by natural disasters, wars, and outbreaks of disease or other adverse public health developments such as the COVID-19 coronavirus outbreak. These events could cause disruptions or restrictions on us, our partners and customers, including restrictions on travel, temporary closure of facilities, and other restrictions. Such disruptions or restrictions may result in delays or losses of sales and delays in the development or implementation of our products. These events could also result in a decrease in consumers’ use of our customers’ services, further adversely affecting our business and operating results.

If our revenues or mix of revenues are below anticipated levels or if our operating results are below analyst or investor expectations, the market price of our common stock could be adversely affected.

A significant percentage of our expenses, particularly personnel and facilities costs, are relatively fixed and based in part on anticipated revenue levels which can be difficult to predict. A decline in revenues without a corresponding and timely slowdown in expense growth could adversely affect our business. Significant revenue shortfalls in any quarter may cause significant declines in operating results since we may be unable to reduce spending in a timely manner.

Quarterly or annual operating results that are below the expectations of public market analysts could adversely affect the market price of our common stock. Factors that could cause fluctuations in our operating results include:

•a change in customer demand for our products, which is highly dependent on our ability to continue to offer innovative technology solutions in very competitive markets;

•the timing of customer orders;

•the timing of product implementations, which are highly dependent on customers’ resources and discretion;

•overall economic conditions, which may affect our customers’ and potential customers’ budgets for information technology expenditures;

•foreign exchange rate volatility, which can have a significant effect on our total revenues and costs when our foreign operations are translated to U.S. dollars;

•the incurrence of costs relating to the integration of software products and operations in connection with acquisitions of technologies or businesses; and

•the timing and market acceptance of new products or product enhancements by either us or our competitors.

ITEM 1C. CYBERSECURITY

Risk Management Strategy

Our cybersecurity risk management strategy is comprised of several key elements and is overseen by our Global Information Security team ("GIS"), which is incorporated into our Enterprise Risk Management ("ERM") function. The oversight of our cybersecurity risk is integrated into our ERM processes and procedures. Our ERM framework integrates our information technology and data management systems and related policies and practices into the larger framework to help guide and prioritize our cybersecurity and information technology-related investments, activities, and risk management strategy. We leverage a variety of risk methodologies and technologies to mitigate the risk of cybersecurity threats and incidents. We have a multi-layer, in-depth approach to technology solutions, including employing applications and tool suites used for perimeter, network, end point and application security, as well as for data recovery, in each case tailored to our systems, data, risk profile and mitigation strategy. At least annually, we review cybersecurity risk as part of our ERM processes and integrate those findings into our overall cybersecurity strategy.

We utilize threat intelligence services from multiple organizations, allowing us to proactively respond to emerging cybersecurity threats. We have also taken steps to address cybersecurity threats at third parties, including service providers, that handle, possess, process, and store our material information. Our Third-Party Risk Management program requires that these third parties maintain certain security controls and we assess their compliance with these requirements.

We have a cybersecurity training program that covers a variety of topics designed to educate our employees about the importance of cybersecurity awareness, highlight typical cybersecurity-related risks and issues (such as phishing attacks and other methods used to attempt to infiltrate systems), and test that awareness using knowledge assessments and simulations. The training is administered to employees on an annual basis, and we use a third-party provider for the content to ensure that the training is periodically updated to incorporate new cybersecurity-related developments and best practices.

In the event of a reported potential cybersecurity incident, GIS determines whether such incident triggers our cybersecurity threat evaluation and response plan (the “Response Plan”). If triggered, our cybersecurity response team, which includes representatives from GIS, our business team, and executive leadership, as needed under the circumstances (the “Cyber Response Team”), is convened. Members of the Cyber Response Team are responsible for developing, recommending and implementing the necessary measures to address the cybersecurity incident, including assessing, containing and mitigating its impact, notifying members of our management, the Audit Committee and the full Board of the cybersecurity incident, and coordinating external communications, in each case as appropriate under the circumstances. The Cyber Response Team is responsible for implementing and monitoring the effectiveness of any remediation plan adopted as a result of the cybersecurity incident.

Our cybersecurity policies, standards, processes, controls, and practices are periodically assessed by third-party consultants. These assessments address a variety of activities including information security maturity assessments, audits, regulatory compliance assessments, and independent reviews of our information security control environment and operating effectiveness. The results of assessments are reported to the Board and Audit Committee. Cybersecurity processes are adjusted based on the information provided from these assessments.

Governance

GIS oversees our cybersecurity program and is responsible for identifying, assessing, monitoring, managing and communicating our cybersecurity risks. GIS is led by our Chief Information Security Officer (“CISO”) and is comprised of information security professionals with a variety of cybersecurity certifications and accreditations. GIS is aided by the Executive Risk Management Committee, which is comprised of senior leaders and subject matter experts throughout our company, including our Chief Information Security Officer (“CISO”) and Chief Compliance Officer (“CCO”), who serve on the committee to assess and mitigate specific business unit risks, promote an understanding of potential issues, and provide risk resolution and prevention support. GIS and the Executive Risk Management Committee are responsible for keeping the Audit Committee apprised of developments with respect to our cybersecurity strategy and risks.

Table of Contents

Our CISO has served in various roles in information technology and information security for more than 30 years, including serving as the Chief Information Security Officer at two other large public companies and has been with ACI since 2015. Our CCO has over 30 years of experience in compliance program leadership and process design, risk management and financial services operations, including serving as Head of Compliance for several banking and financial services technology organizations including two other publicly traded companies.

The Audit Committee oversees our cybersecurity strategy and risks. The Audit Committee is provided with cybersecurity strategy and risk updates on a quarterly, or as needed, basis. In addition, the Board is provided with an annual cybersecurity update that addresses similar topics to those discussed with the Audit Committee on a quarterly basis.

ITEM 2. PROPERTIES

We lease office space in Elkhorn, Nebraska, for our principal executive offices. As of the end of 2023, we owned and leased a total of approximately 286,000 square feet of office and data center space in the United States and leased approximately 332,000 square feet of office and data center space outside the United States, primarily in India, Ireland, South Africa, Romania, and Singapore.

We believe our current facilities are adequate for our present and short-term foreseeable needs and that additional suitable space will be available as required. We also believe we will be able to renew leases as they expire or secure alternate suitable space.

See Note 12, Leases, to our Notes to Consolidated Financial Statements in Part IV, Item 15 of this Form 10-K for additional information regarding our obligations under our facilities leases.

PART II

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITY SECURITIES

Our common stock trades on The NASDAQ Global Select Market under the symbol ACIW.

As of February 27, 2024, there were 229 holders of record of our common stock. A substantially greater number of shareholders hold our common stock in “street name”, or as beneficial holders whose shares are held in the name of banks, brokers, or other financial institutions.

For equity compensation plan information, please refer to Item 12 in Part III of this Annual Report.

Dividends

We have never declared nor paid cash dividends on our common stock. We do not presently anticipate paying cash dividends. However, any future determination relating to our dividend policy will be made at the discretion of our board of directors (the "board") and will depend upon our financial condition, capital requirements, and earnings, as well as other factors the board may deem relevant. The terms of our current Credit Facility may restrict the payment of dividends subject to us meeting certain financial metrics and being in compliance with the events of default provisions of the agreement.

Issuer Purchases of Equity Securities

The following table provides information regarding our repurchases of common stock during the three months ended December 31, 2023:


Period	Total Number of Shares Purchased	Average Price Paid per Share		Total Number of Shares Purchased as Part of Publicly Announced Program	Approximate Dollar Value of Shares that May Yet Be Purchased Under the Program
October 1, 2023 through October 31, 2023	—	$	—	—	$	200,000,000
November 1, 2023 through November 30, 2023 (1)	35,997	26.10		—	200,000,000
December 1, 2023 through December 31, 2023 (1)	939,764	29.36		939,567	172,413,000
Total	975,761	$	29.24	939,567

(1)Pursuant to our 2016 and 2020 Equity and Performance Incentive Plans, (the "2016 Incentive Plan" and "2020 Incentive Plan"), we granted RSUs. Under each arrangement, shares are issued without direct cost to the employee. During the three months ended December 31, 2023, 112,536 shares of RSUs vested. We withheld 36,194 of these RSUs to pay the employees’ portion of the applicable minimum payroll withholding taxes.

In 2005, our board approved a stock repurchase program authorizing us, as market and business conditions warrant, to acquire our common stock and periodically authorizes additional funds for the program, with the intention of using existing cash and cash equivalents to fund these repurchases. On February 24, 2023, the board approved the repurchase of the Company's common stock for up to $200.0 million, in place of the remaining purchase amounts previously authorized. As of December 31, 2023, the maximum remaining amount authorized for purchase under the stock repurchase program was approximately $172.4 million.

Table of Contents

There is no guarantee as to the exact number of shares we will repurchase. Repurchased shares are returned to the status of authorized but unissued shares of common stock. In March 2005, our board approved a plan under Rule 10b5-1 of the Securities Exchange Act of 1934 to facilitate the repurchase of shares of common stock under the existing stock repurchase program. Under our Rule 10b5-1 plan, we have delegated authority over the timing and amount of repurchases to an independent broker who does not have access to inside information about the Company. Rule 10b5-1 allows us, through the independent broker, to purchase shares at times when we ordinarily would not be in the market because of self-imposed trading blackout periods, such as the time immediately preceding the end of the fiscal quarter through a period of three business days following our quarterly earnings release.

Stock Performance Graph and Cumulative Total Return

The following table shows a line-graph presentation comparing cumulative stockholder return on an indexed basis with a broad equity market index and either a nationally-recognized industry standard or an index of peer companies selected by us. We selected the S&P 500 Index and the S&P MidCap 400 Index for comparison.

The graph above compares ACI Worldwide, Inc.’s annual percentage change in cumulative total return on common shares over the past five years with the cumulative total return of companies comprising the S&P 500 Index and the S&P MidCap 400 Index. This presentation assumes that $100 was invested in shares of the relevant issuers on December 31, 2018, and that dividends received were immediately invested in additional shares. The graph plots the value of the initial $100 investment at one-year intervals for the fiscal years shown. This information was provided by Zacks Investment Research, Inc. of Chicago, Illinois.

The stock performance graph disclosure above is not considered “filed” with the SEC under the Securities and Exchange Act of 1934, as amended, and is not incorporated by reference in any past or future filing by us under the Securities Exchange Act of 1934, as amended, or the Securities Act of 1933, as amended, unless specifically referenced.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

ACI Worldwide powers digital payments for more than 6,000 organizations around the world. More than 1,000 of the largest banks and intermediaries, as well as thousands of global merchants, rely on ACI to execute $14 trillion each day in payments and securities. In addition, myriad organizations utilize our electronic bill presentment and payment services. Through our comprehensive suite of software solutions delivered on customers’ premises, through the public cloud or through ACI’s private cloud, we provide real-time, immediate payments capabilities and enable the industry’s most complete omni-channel payments experience.

Our products are sold and supported directly and through distribution networks covering three geographic regions – the Americas, EMEA, and Asia Pacific. Each region has its own globally coordinated sales force, supplemented with local independent reseller and/or distributor networks. Our products and solutions are marketed under the ACI Worldwide brand and used globally by banks and intermediaries, merchants, and billers, such as third-party electronic payment processors, payment associations, switch interchanges, and a wide range of transaction-generating endpoints, including ATMs, merchant POS terminals, bank branches, mobile phones, tablets, corporations, and internet commerce sites.

We derive a majority of our revenues from domestic operations and believe we have large opportunities for growth in international markets, as well as continued expansion domestically in the United States. We also continue to maintain centers of expertise in Timisoara, Romania, and Pune and Bangalore in India, as well as key operational centers such as in Cape Town, South Africa and in multiple locations in the United States.

Our business and operating results are influenced by trends such as information technology spending levels, the growth rate of digital payments, mandated regulatory changes, and changes in the number and type of customers in the financial services industry, as well as economic growth, and purchasing habits.

Key trends that currently impact our strategies and operations include:

Increasing digital payment transaction volumes. The adoption of digital payments continues to accelerate, propelled by the digitization of cash, financial inclusion efforts of countries throughout the world, the Internet of Things, rapid growth of eCommerce and the adoption of real-time payments. COVID-19 further accelerated this growth as more people, governments, and businesses embraced digital payments - a change that has continued. We leverage the growth in transaction volumes through the licensing of new systems to customers whose older systems cannot handle increased volume, through the sale of capacity upgrades to existing customers, and through the scalability of our platform-based solutions.

Adoption of real-time payments. Expectations from both consumers and businesses are continuing to drive the payments world to more real-time delivery. This is bolstered by the new data-rich ISO 20022 messaging format, which is delivering greater value to banks and their customers. We are seeing global players with existing schemes working to expand capacity in anticipation of volume growth and new payment types. Mature markets, including India, the United Kingdom, Australia, Malaysia, Singapore, Thailand, and the Nordics, continue to accelerate innovation, especially in terms of overlay services and cross-border connectivity. The United States is driving real-time payments adoption through Zelle, TCH Real-Time Payments, and the FedNow service. We are seeing success with real-time payments in the Middle East as well, as they have started to renovate their payment systems from legacy payment types to the modern digital and real-time world. ACI's broad software portfolio, experience, and strategic partnerships with Mastercard, Microsoft, and Mindgate Solutions continue to position us as a leader in real-time payments, helping to drive seamless connectivity, increased security, and end-to-end modernization for organizations throughout the world.

Adoption of cloud technology. ACI has recognized the industry's technical inflection point in the transition from traditional on-premises infrastructure to the public cloud, and we are supporting our customers' cloud strategies. Public and private cloud technology innovations allow the financial services ecosystem to accelerate innovation and ensure scalability and resiliency while improving operating economics over time. As banks and intermediaries, merchants, and billers seek to transition their systems to make use of cloud technology, our investments and partnerships, as demonstrated by our product enablement and initial optimization onto Microsoft Azure, enable us to leverage those cloud technology benefits today and for the future while preserving ACI's fundamental base of performance, resiliency, and scalability.

Payments intelligence. fraud, and compliance. The accelerated adoption of real-time payments increases the urgency for industry-wide collaboration against fraud. As the threat of scams becomes a greater concern for remitting and receiving institutions, consumers are challenged with increased friction to prevent account take-over and criminals successfully persuading consumers to push transactions themselves, inadvertently, to mule accounts they have full control of, created with fake or synthetic identity, or simply "borrowed" with or without consent of the legit account holders. Regulators are beginning to litigate between consumers and financial institutions on the losses, and between remitting and receiving banks on the accountability for reimbursement. Banks and intermediaries, merchants, and billers are pursuing solutions to mitigate their risks while improving their customer experience, protecting their margins, and securing their revenue streams, especially with their new products and offerings. We continue to see opportunity for our advanced machine learning and network intelligence capabilities to stop criminals and enable frictionless legitimate business.

Omni-commerce. Shoppers are increasingly browsing, buying, and returning items across channels, including in-store, online, and mobile. COVID-19 accelerated this trend, leading to an increase in contactless payments, click and collect, and curbside collection. Merchants from all industries, including grocers, fuel and convenience stores, are being tasked with delivering seamless experiences that include pay-in-aisle, kiosks, mobile app payments, QR code payments, eCommerce, traditional and mobile POS, buy online pickup in-store (BOPIS), and buy online return in-store (BORIS). We believe there is significant opportunity to provide merchants with the tools to deliver a seamless, secure, personalized experience that creates loyalty and satisfaction, and drives conversion rates while protecting consumer data and preventing fraud.

Request for Payment (RfP). Markets across the world are introducing an innovative payments service called Request for Payment (RfP). This technology is known by different names in different markets: Collect payments in India, Request 2 Pay in Europe, Request To Pay (RTP) in the United Kingdom, or Request for Payment (RfP) in the United States. RfP offers secure messaging between consumers and billers or merchants, wherein a biller or merchant can request a payment from a consumer through the use of a trusted app, most likely a banking app. RfP is primarily being implemented on top of real-time payments, which are continuing to grow and flourish as countries around the world develop and launch their real-time schemes as noted above. ACI is in a unique position to deliver this overlay service given our real-time payments software, our relationships with banks, merchants, and billers, and global real-time connectivity.

Several other factors related to our business may have a significant impact on our operating results from year to year. For example, the accounting rules governing the timing of revenue recognition are complex, and it can be difficult to estimate when we will recognize revenue generated by a given transaction. Factors such as creditworthiness of the customer and timing of transfer of control or acceptance of our products may cause revenues related to sales generated in one period to be deferred and recognized in later periods. For arrangements in which services revenue is deferred, related direct and incremental costs may also be deferred. Additionally, while the majority of our contracts are denominated in the U.S. dollar, a substantial portion of our sales are made, and some of our expenses are incurred, in the local currency of countries other than the United States. Fluctuations in currency exchange rates in a given period may result in the recognition of gains or losses for that period.

We continue to seek ways to grow through organic sources, partnerships, alliances, and acquisitions. We continually look for potential acquisitions designed to improve our solutions’ breadth or provide access to new markets. As part of our acquisition strategy, we seek acquisition candidates that are strategic, capable of being integrated into our operating environment, and accretive to our financial performance.

Divestiture

On September 1, 2022, we sold our corporate online banking solutions related assets and liabilities to One Equity Partners ("OEP") for $100.0 million, and a net working capital adjustment. The sale included employees and customer contracts as well as technology assets and intellectual property.

For the year ended December 31, 2022, we recognized a gain of $38.5 million on the sale, which is recorded in other, net in the accompanying consolidated statements of operations. During the year ended December 31, 2023, the Company recognized a loss for the final post-closing adjustment pursuant to the definitive agreement of $0.5 million, which is recorded in other, net in the accompanying consolidated statements of operations.

The Company and OEP have also entered into a Transition Services Agreement ("TSA"), whereby the Company will continue to perform certain functions on OEP's behalf during a migration period. The TSA is meant to reimburse the Company for direct costs in order to provide such functions, which are no longer generating revenue for the Company.

Backlog

Backlog is comprised of:

•Committed Backlog, which includes (1) contracted revenue that will be recognized in future periods (contracted but not recognized) from software license fees, maintenance fees, service fees, and SaaS and PaaS fees specified in executed contracts (including estimates of variable consideration if required under ASC 606) and included in the transaction price for those contracts, which includes deferred revenue and amounts that will be invoiced and recognized as revenue in future periods and (2) estimated future revenues from software license fees, maintenance fees, services fees, and SaaS and PaaS fees specified in executed contracts.

•Renewal Backlog, which includes estimated future revenues from assumed contract renewals to the extent we believe recognition of the related revenue will occur within the corresponding backlog period.

We have historically included assumed renewals in backlog estimates based upon automatic renewal provisions in the executed contract and our historic experience with customer renewal rates.

Our 60-month backlog estimates are derived using the following key assumptions:

•License arrangements are assumed to renew at the end of their committed term or under the renewal option stated in the contract at a rate consistent with historical experience. If the license arrangement includes extended payment terms, the renewal estimate is adjusted for the effects of a significant financing component.

•Maintenance fees are assumed to exist for the duration of the license term for those contracts in which the committed maintenance term is less than the committed license term.

•SaaS and PaaS arrangements are assumed to renew at the end of their committed term at a rate consistent with our historical experiences.

•Foreign currency exchange rates are assumed to remain constant over the 60-month backlog period for those contracts stated in currencies other than the U.S. dollar.

•Our pricing policies and practices are assumed to remain constant over the 60-month backlog period.

In computing our 60-month backlog estimate, the following items are specifically not taken into account:

•Anticipated increases in transaction, account, or processing volumes by our customers.

•Optional annual uplifts or inflationary increases in recurring fees.

•Services engagements, other than SaaS and PaaS arrangements, are not assumed to renew over the 60-month backlog period.

•The potential impact of consolidation activity within our markets and/or customers.

We review our customer renewal experience on an annual basis. The impact of this review and subsequent updates may result in a revision to the renewal assumptions used in computing the 60-month backlog estimates. In the event a significant revision to renewal assumptions is determined to be necessary, prior periods will be adjusted for comparability purposes.

The following table sets forth our 60-month backlog estimate, by reportable segment, as of December 31, 2023; September 30, 2023; June 30, 2023; March 31, 2023; and December 31, 2022 (in millions). Dollar amounts reflect foreign currency exchange rates as of each period end. This is a non-GAAP financial measure being presented to provide comparability across accounting periods. We believe this measure provides useful information to investors and others in understanding and evaluating our financial performance.

Estimates of future financial results require substantial judgment and are based on several assumptions, as described above. These assumptions may turn out to be inaccurate or wrong for reasons outside of management’s control. For example, our customers may attempt to renegotiate or terminate their contracts for many reasons, including mergers, changes in their financial condition, or general changes in economic conditions in the customer’s industry or geographic location. We may also experience delays in the development or delivery of products or services specified in customer contracts, which may cause the actual renewal rates and amounts to differ from historical experiences. Changes in foreign currency exchange rates may also impact the amount of revenue recognized in future periods. Accordingly, there can be no assurance that amounts included in backlog estimates will generate the specified revenues or that the actual revenues will be generated within the corresponding 60-month period. Additionally, because certain components of Committed Backlog and all of Renewal Backlog estimates are operating metrics, the estimates are not required to be subject to the same level of internal review or controls as contracted but not recognized Committed Backlog.

Software as a Service (“SaaS”) and Platform as a Service (“PaaS”) Revenue

The Company’s SaaS arrangements allow customers to use certain software solutions (without taking possession of the software) in a single-tenant cloud environment on a subscription basis. The Company’s PaaS arrangements allow customers to use certain software solutions (without taking possession of the software) in a multi-tenant cloud environment on a subscription or consumption basis. Included in SaaS and PaaS revenue are fees paid by our customers for use of our Biller solutions. Biller-related fees may be paid by our clients or directly by their customers and may be a percentage of the underlying transaction amount, a fixed fee per executed transaction or a monthly fee for each customer enrolled. SaaS and PaaS costs include payment card interchange fees, the amounts payable to banks and payment card processing fees, which are included in cost of revenue in the accompanying consolidated statements of operations. All revenue from SaaS and PaaS arrangements that does not qualify for treatment as a distinct performance obligation, which includes set-up fees, implementation or customization services, and product support services, are included in SaaS and PaaS revenue.

License Revenue

Customers purchase the right to license ACI software under multi-year, time-based software license arrangements that vary in length but are generally five years. Under these arrangements the software is installed at the customer’s location (i.e. on-premise). Within these agreements are specified capacity limits typically based on customer transaction volume. ACI employs measurement tools that monitor the number of transactions processed by customers and if contractually specified limits are exceeded, additional fees are charged for the overage. Capacity overages may occur at varying times throughout the term of the agreement depending on the product, the size of the customer, and the significance of customer transaction volume growth. Depending on specific circumstances, multiple overages or no overages may occur during the term of the agreement.

Included in license revenue are license and capacity fees that are payable at the inception of the agreement or annually (initial license fees). License revenue also includes license and capacity fees payable quarterly or monthly due to negotiated customer payment terms (monthly license fees). The Company recognizes revenue in advance of billings for software license arrangements with extended payment terms and adjusts for the effects of the financing component, if significant.

License revenue decreased $26.9 million, or 8%, during the year ended December 31, 2023, as compared to the same period in 2022.

•The impact of certain foreign currencies weakening against the U.S. dollar resulted in a $0.7 million decrease in license revenue during the year ended December 31, 2023, as compared to the same period in 2022.

•Adjusted for the impact of foreign currency, license revenue for the year ended December 31, 2023, decreased $26.2 million, or 8%, as compared to the same period in 2022.

Segment Results

The Company reports financial performance based on its operating segments, Banks, Merchants, and Billers, and analyzes Segment Adjusted EBITDA as a measure of segment profitability.

The Company’s Chief Executive Officer is also the chief operating decision maker ("CODM"). The CODM, together with other senior management personnel, focus their review on consolidated financial information and the allocation of resources based on operating results, including revenues and Segment Adjusted EBITDA, for each segment, separate from corporate operations. No operating segments have been aggregated to form the reportable segments.

Banks. ACI provides payment solutions to large and mid-size banks globally for retail banking, real time, digital, and other payment services. These solutions transform banks’ complex payment environments to speed time to market, reduce costs, and deliver a consistent experience to customers across channels while enabling them to prevent and rapidly react to fraudulent activity. In addition, they enable banks to meet the requirements of different real-time payments schemes and to quickly create differentiated products to meet consumer, business, and merchant demands.

Merchants. ACI’s support of merchants globally includes Tier 1 and Tier 2 merchants, online-only merchants and the payment service providers, independent selling organizations, value-added resellers, and acquirers who service them. These customers operate in a variety of verticals, including general merchandise, grocery, hospitality, dining, transportation, and others. The Company's solutions provide merchants with a secure, omni-channel payments platform that gives them independence from third-party payment providers. They also offer secure solutions to online-only merchants that provide consumers with a convenient and seamless way to shop.

Billers. Within the billers segment, ACI provides electronic bill presentment and payment (“EBPP”) services to companies operating in the consumer finance, insurance, healthcare, higher education, utility, government, and mortgage categories. The solutions enable these customers to support a wide range of payment options and provide a convenient consumer payments experience that drives consumer loyalty and increases revenue.

Revenue is attributed to the reportable segments based upon the customer. Expenses are attributed to the reportable segments in one of three methods: (1) direct costs of the segment, (2) labor costs that can be attributed based upon time tracking for individual projects, or (3) costs that are allocated. Allocated costs are generally marketing and sales related activities.

Segment Adjusted EBITDA is the measure reported to the CODM for purposes of making decisions on allocating resources and assessing the performance of the Company's segments and, therefore, Segment Adjusted EBITDA is presented in conformity with ASC 280, Segment Reporting. Segment Adjusted EBITDA is defined as earnings (loss) from operations before interest, income tax expense (benefit), depreciation and amortization (“EBITDA”) adjusted to exclude net other income (expense).

Corporate and unallocated expenses includes global facilities and information technology costs and long-term product roadmap expenses in addition to the corporate overhead costs that are not allocated to reportable segments. The overhead costs relate to human resources, finance, legal, accounting, and merger and acquisition activity. These costs along with depreciation and amortization and stock-based compensation are not considered when management evaluates segment performance.

Banks Segment Adjusted EBITDA decreased $13.9 million due to the divestiture. Excluding the divestiture, Banks Segment Adjusted EBITDA decreased $1.6 million for the year ended December 31, 2023, compared to the same period in 2022, primarily due to a $11.2 million increase in cash operating expense, partially offset by a $9.6 million increase in revenue.

Merchants Segment Adjusted EBITDA decreased $4.7 million for the year ended December 31, 2023, compared to the same period in 2022, primarily due to a $3.3 million decrease in revenue and a $1.4 million increase in cash operating expenses.

Billers Segment Adjusted EBITDA increased $35.0 million for the year ended December 31, 2023, compared to the same period in 2022, primarily due to a $56.5 million increase in revenue, partially offset by a $14.5 million increase in interchange and processing fees.

Liquidity and Capital Resources

General

Our primary liquidity needs are: (i) to fund normal operating expenses; (ii) to meet the interest and principal requirements of our outstanding indebtedness; and (iii) to fund acquisitions, capital expenditures, and lease payments. We believe these needs will be satisfied using cash flow generated by our operations, cash and cash equivalents, and available borrowings under our revolving credit facility over the next 12 months and beyond.

Table of Contents

Cash and cash equivalents consist of highly liquid investments with original maturities of three months or less. As of December 31, 2023, we had $164.2 million of cash and cash equivalents, of which $60.9 million was held by our foreign subsidiaries. If these funds were needed for our operations in the United States, we may potentially be required to accrue and pay foreign and U.S. state income taxes to repatriate these funds. As of December 31, 2023, only the earnings in our Indian foreign subsidiaries are indefinitely reinvested. The earnings of all other foreign entities are no longer indefinitely reinvested. We are also permanently reinvested for outside book/tax basis differences related to foreign subsidiaries. These outside basis differences could reverse through sales of the foreign subsidiaries, as well as various other events, none of which are considered probable as of December 31, 2023.

Available Liquidity

The following table sets forth our available liquidity for the periods indicated (in thousands):


	December 31,
	2023		2022
Cash and cash equivalents	$	164,239	$	124,981
Availability under revolving credit facility	373,900		393,500
Total liquidity	$	538,139	$	518,481

The Company and ACI Payments, Inc., a wholly owned subsidiary, maintain a $75.0 million uncommitted overdraft facility with Bank of America, N.A. The overdraft facility acts as a secured loan under the terms of the Credit Agreement to provide an additional funding mechanism for timing differences that can occur in the bill payment settlement process. As of December 31, 2023, the full $75.0 million was available.

On February 26, 2024, we entered into a Refinance Amendment (the “Amendment”) to the Second Amended and Restated Credit Agreement, dated as of April 5, 2019 (as amended, restated, supplemented or otherwise modified from time to time, including by the Amendment, the “Credit Agreement”) with ACI Worldwide Corp and ACI Payments, Inc. as co-borrowers, the lenders, and Bank of America N.A, as administrative agent and lender. The Amendment, among other things, (i) provides a senior secured term loan facility in an aggregate principal amount of $500 million, (ii) provides a senior secured revolving credit facility in an aggregate principal amount of $600 million, and (iii) extends the maturity date of the Facilities to February 26, 2029. The proceeds of the borrowings under the Amendment, together with cash on hand, were used to refinance all outstanding borrowings and replace all existing revolving commitments under the Credit Agreement immediately prior to the date of the Amendment and will be used to provide ongoing working capital and for other general corporate purposes.

Stock Repurchase Program

Our board approved a stock repurchase program authorizing the Company, as market and business conditions warrant, to acquire its common stock and periodically authorizes additional funds for the program. In February 2023, the board approved the repurchase of the Company's common stock of up to $200.0 million, in place of the remaining purchase amounts previously authorized.

We repurchased 939,567 shares for $27.6 million under our stock repurchase program during the year ended December 31, 2023. Under the program to date, we have repurchased 58,921,300 shares for approximately $953.8 million. As of December 31, 2023, the maximum remaining amount authorized for purchase under the stock repurchase program was approximately $172.4 million.

Subsequent to December 31, 2023, the Company has repurchased additional shares under the repurchase program.

Our stock repurchase authorization does not have an expiration date and the pace of our repurchase activity will depend on factors such as our working capital needs, cash requirements for acquisitions, debt repayment obligations, our stock price, and global economic and market conditions. Our stock repurchases may be affected from time to time through open market purchases and pursuant to a Rule 10b5-1 plan and they may be accelerated, suspended, delayed or discontinued at any time. See Note 7, Common Stock and Treasury Stock, to our Notes to Consolidated Financial Statements in Part IV, Item 15 of this Form 10-K for additional information.

Cash Flows

The following table sets forth summary cash flow data for the periods indicated (in thousands).


	Years Ended December 31,
	2023		2022
Net cash provided by (used in):
Operating activities	$	168,517	$	143,381
Investing activities	(37,777)		60,246
Financing activities	(111,552)		(171,060)

Cash Flows from Operating Activities

The primary source of operating cash flows is cash collections from our customers for purchase and renewal of licensed software products and various services including software and platform as a service, maintenance, and other professional services. Our primary uses of operating cash flows includes employee expenditures, taxes, interest payments, and leased facilities.

Cash flows provided by operating activities were $25.1 million higher for the year ended December 31, 2023, compared to the same period in 2022. This increase is primarily due to $69.2 million more in customer receipt collections on higher prior year-end receivable balances, partially offset by $25.0 million more in interest payments due to the increase in interest rates, and $21.9 million more in income tax payments, which is based upon higher pre-tax income in the prior year.

Our cash flow from operating activities can fluctuate from period to period due to several factors, including: the timing of billings, which are typically higher in the third and fourth quarters in conjunction with sales timing and are variable based upon license renewal timing; collections, which will lag the quarters with higher billings; the timing and amounts of interest due to interest rate fluctuations and semi-annual Senior Notes interest payments; income tax and other payments; and our operating results.

Cash Flows from Investing Activities

The changes in cash flows from investing activities primarily relate to the timing of our purchases and investments in capital and other assets, including strategic acquisitions, that support our growth.

During the year ended December 31, 2023, we used cash of $37.8 million to purchase software, property, and equipment, as compared to $39.9 million during the same period in 2022. During the year ended December 31, 2022, we received net proceeds of $100.1 million from the divestiture.

Cash Flows from Financing Activities

The changes in cash flows from financing activities primarily relate to borrowings and repayments related to our debt instruments and other debt, stock repurchases, and net proceeds related to employee stock programs.

During 2023, we repaid $73.0 million on the Term Loans, $16.8 million of other debt payments, and $2.2 million of debt issuance costs. In addition, we used $27.6 million to repurchase common stock, $5.1 million for the repurchase of stock-based compensation awards for tax withholdings, and $15.4 million for settlement assets and liabilities due to processing timing. We received net proceeds of $19.0 million on the Revolving Credit Facility, and proceeds of $9.5 million from the exercise of stock options and the issuance of common stock under our 2017 Employee Stock Purchase Plan, as amended. During 2022, we used the proceeds from the divestiture to partially fund repayments of $85.4 million on the Term Loans and $12.1 million of other debt payments. In addition, we used $206.5 million to repurchase common stock and $7.0 million for the repurchase of stock-based compensation awards for tax withholdings. We received net proceeds of $105.0 million on the Revolving Credit Facility, proceeds of $8.2 million from the exercise of stock options and the issuance of common stock under our 2017 Employee Stock Purchase Plan, as amended, and $26.8 million from settlement assets and liabilities due to processing timing.

Contractual Obligations

Our largest contractual obligations as of December 31, 2023, include the following:

•principal payments related to our Credit Agreement that are included in our consolidated balance sheet and the related periodic interest payments;

•semi-annual interest payments on our 2026 Notes and the ultimate principal payment that is included in our consolidated balance sheet;

•scheduled payments related to liabilities for certain multi-year license agreements for internal-use software that are included in our consolidated balance sheet;

•operating lease obligations that are included in our consolidated balance sheet; and

•other contractual commitments associated with agreements that are enforceable and legally binding.

In addition, we have gross unrecognized income tax benefits, including related interest and penalties, recorded on our consolidated balance sheet, the nature of which is uncertain with respect to settlement or release with the relevant tax authorities. See Note 11, Income Taxes, of our Notes to Consolidated Financial Statements in Part IV, Item 15 of this Form 10-K.

Notes 4, Debt, 12, Leases, and 13, Commitments and Contingencies, of our Notes to Consolidated Financial Statements in Part IV, Item 15 of this Form 10-K provide additional information regarding our contractual obligations and contingencies.

Critical Accounting Policies and Estimates

The preparation of the consolidated financial statements requires that we make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We base our estimates on historical experience and other assumptions that we believe to be proper and reasonable under the circumstances. We continually evaluate the appropriateness of estimates and assumptions used in the preparation of our consolidated financial statements. Actual results could differ from those estimates.

The following key accounting policies are impacted significantly by judgments, assumptions, and estimates used in the preparation of the consolidated financial statements. See Note 1, Nature of Business and Summary of Significant Accounting Policies, and Note 2, Revenue, to our Notes to Consolidated Financial Statements in Part IV, Item 15 of this Form 10-K for a further discussion of significant accounting policies and revenue recognition.

Revenue Recognition

In accordance with ASC 606, Revenue From Contracts with Customers, revenue is recognized upon transfer of control of promised products and/or services to customers in an amount that reflects the consideration we expect to be entitled to receive in exchange for those products and services.

Our software license arrangements provide the customer with the right to use functional intellectual property for the duration of the contract term. Implementation, support, and other services are typically considered distinct performance obligations when sold with a software license. Significant judgment is required to determine the stand-alone selling price (“SSP”) for each performance obligation, the amount allocated to each performance obligation and whether it depicts the amount that we expect to be entitled to receive in exchange for the related product and/or service. As the selling prices of our software licenses are highly variable, we estimate SSP of our software licenses using the residual approach when the software license is sold with other services and observable SSPs exist for the other services. We use a range of amounts to estimate SSP for maintenance and services. These ranges are based on stand-alone sales and vary based on the type of service and geographic region. If the SSP of a performance obligation is not directly observable, we will maximize observable inputs to determine its SSP.

When a software license arrangement contains payment terms that are extended beyond one year, a significant financing component may exist. The significant financing component is calculated as the difference between the stated value and present value of the software license fees and is recognized as interest income over the extended payment period. Judgment is used in determining: (1) whether the financing component in a software license agreement is significant and, if so, (2) the discount rate used in calculating the significant financing component.

We assess the significance of the financing component based on the ratio of license fees paid over time to total license fees. If determined to be significant, the financing component is calculated using a rate that discounts the license fees to the cash selling price.

Table of Contents

Our SaaS-based and PaaS-based arrangements represent a single promise to provide continuous access to our software solutions and their processing capabilities in the form of a service through one of our data centers. These arrangements may include fixed and/or variable consideration. Fixed consideration is recognized over the term of the arrangement and variable consideration, which is a function of transaction volume or another usage-based measure, generally meets the allocation objective and revenue is recognized as the usage occurs.

We apply judgment in determining the customer’s ability and intention to pay, which is based on a variety of factors including the creditworthiness of the customer, economic conditions in the customer’s industry and geographic location, and general economic conditions.

Certain of our arrangements are through unrelated distributors or sales agents. For software license arrangements in which we act as a distributor of another company’s product, and in certain circumstances, modify or enhance the product, revenues are recorded on a gross basis. These include arrangements in which we take control of the products and are responsible for providing the product or service. For software license arrangements in which we act as a sales agent for another company’s product, revenues are recorded on a net basis. Judgment is required in evaluating the facts and circumstances of our relationship with the distributor or sales agent as well as our operating history and practices that can impact the timing of revenue recognition related to these arrangements. For software license arrangements in which we utilize a third-party distributor or sales agent, we recognize revenue upon transfer of control of the software license(s) to the third-party distributor or sales agent.

We may execute more than one contract or agreement with a single customer at or near the same time. The separate contracts or agreements may be viewed as one combined arrangement or separate agreements for revenue recognition purposes. We evaluate whether the agreements were negotiated as a package with a single commercial objective, whether the products or services promised in the agreements represent a single performance obligation, or whether the amount of consideration to be paid in one agreement depends on the price and/or performance of another agreement to reach appropriate conclusions regarding whether such arrangements are related or separate. The conclusions reached can impact the allocation of the transaction price to each performance obligation and the timing of revenue recognition related to those arrangements.

Intangible Assets and Goodwill

Our business acquisitions typically result in the recording of intangible assets. As of December 31, 2023 and 2022, our intangible assets, excluding goodwill, net of accumulated amortization, were $195.6 million and $228.7 million, respectively. The determination of the value of such intangible assets requires management to make estimates and assumptions that affect the consolidated financial statements. We assess potential impairments to intangible assets when there is evidence that events or changes in circumstances indicate the carrying amount of an asset may not be recovered. Judgments regarding the existence of impairment indicators and future cash flows related to intangible assets are based on operational performance of our businesses, market conditions, and other factors. Although there are inherent uncertainties in this assessment process, the estimates and assumptions used, including estimates of future cash flows, volumes, market penetration and discount rates, are consistent with our internal planning. If these estimates or their related assumptions change in the future, we may be required to record an impairment charge on all or a portion of our intangible assets. Furthermore, we cannot predict the occurrence of future impairment-triggering events nor the impact such events might have on our reported asset values. Future events could cause us to conclude that impairment indicators exist and that intangible assets associated with acquired businesses are impaired. Any resulting impairment loss could have an impact on our results of operations.

Other intangible assets are amortized using the straight-line method over periods ranging from four to 20 years.

As of December 31, 2023 and 2022, our goodwill was $1.2 billion. In accordance with ASC 350, Intangibles – Goodwill and Other, we assess goodwill for impairment annually during the fourth quarter of our fiscal year using October 1 balances, or when there is evidence that events or changes in circumstances indicate that the carrying amount of the asset may not be recovered. We evaluate goodwill at the reporting unit level and have identified our reportable segments, Banks, Merchants, and Billers, as our reporting units. Recoverability of goodwill is measured using a discounted cash flow valuation model incorporating discount rates commensurate with the risks involved. Use of a discounted cash flow valuation model is common practice in impairment testing in the absence of available transactional market evidence to determine the fair value.

Table of Contents

The key assumptions used in the discounted cash flow valuation model include discount rates, growth rates, cash flow projections, and terminal value rates. Discount rates, growth rates, and cash flow projections are the most sensitive and susceptible to change, as they require significant management judgment. Discount rates are determined by using a weighted average cost of capital (“WACC”). The WACC considers market and industry data, as well as Company-specific risk factors. Operational management, considering industry and Company-specific historical and projected data, develops growth rates and cash flow projections for each reporting unit. Terminal value rate determination follows common methodology of capturing the present value of perpetual cash flow estimates beyond the last projected period assuming a constant WACC and low long-term growth rates. If the calculated fair value is less than the current carrying value, impairment of the reporting unit may exist. The implied fair value of goodwill is determined in a manner similar to how goodwill is calculated in a business combination. If the implied fair value of goodwill exceeds the carrying value of goodwill assigned to the reporting unit, there is no impairment. If the carrying value of goodwill assigned to the reporting unit exceeds the implied fair value of the goodwill, an impairment charge is recorded to write down the carrying value. The calculated fair value substantially exceeds the current carrying value for all reporting units. No reporting units were deemed to be at risk of failing Step 1 of the goodwill impairment test under ASC 350.

Business Combinations

We apply the provisions of ASC 805, Business Combinations, in the accounting for our acquisitions. It requires us to recognize the assets acquired and the liabilities assumed at their acquisition date fair values, separately from goodwill. Goodwill as of the acquisition date is measured as the excess of consideration transferred and the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While we use our best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date, estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements of operations.

Critical estimates in valuing certain intangible assets include but are not limited to future expected cash flows from customer relationships, covenants not to compete, and acquired developed technologies; brand awareness and market position, as well as assumptions about the period of time the brand will continue to be used in our product portfolio; and discount rates. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates.

Other estimates associated with the accounting for acquisitions may change as additional information becomes available regarding the assets acquired and liabilities assumed.

Stock-Based Compensation

On June 9, 2020, upon recommendation of our board, stockholders approved the ACI Worldwide, Inc. 2020 Equity and Incentive Compensation Plan (the “2020 Plan”). The 2020 Plan authorizes the board to provide for equity-based compensation in the form of stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units, dividend equivalents, and certain other awards, including those denominated or payable in, or otherwise based on, our common stock ("awards"). The purpose of the 2020 Plan is to provide incentives and rewards for service and/or performance by providing awards to non-employee directors, officers, other employees, and certain consultants and other service providers of us and our subsidiaries. Following the approval of the 2020 Plan, the 2016 Incentive Plan was terminated. Termination of the 2016 Incentive Plan did not affect any equity awards outstanding under the 2016 Incentive Plan or 2005 Incentive Plan.

Performance awards granted with a total shareholder return multiplier ("TSRs") are shares that are earned, if at all, based upon achievement of performance goals over a specified period. For 2023, performance awards granted are earned over a specified period that must not be less than one year and is typically a three-year performance period, based upon achievement of performance goals related to (i) net revenue growth and (ii) net adjusted EBITDA margin over the performance period as determined by the Company with a total shareholder return multiplier up to plus or minus 20%. Up to 200% of the performance shares could be earned upon achievement of the performance goals, including the multiplier. For 2022 and 2021, we granted performance shares that are earned based upon the Company’s total shareholder return as compared to a group of peer companies over a three-year performance period. The award payout can range from 0% to 200%. To determine the grant date fair value of the TSRs, a Monte Carlo simulation model is used. We recognize compensation expense for the TSRs over the performance period based on the grant date fair value.

Table of Contents

Restricted share unit awards (“RSUs”) generally have requisite service periods of three years and may vest 100% upon the three-year anniversary or in equal increments quarterly or annually. Under each arrangement, RSUs are issued without direct cost to the employee on the vesting date. We estimate the fair value of RSUs based upon the market price of our stock on the date of grant. We recognize compensation expense for RSUs on a straight-line basis over the requisite service period.

The assumptions utilized in the Monte Carlo simulation models, as well as the description of the plans the stock-based awards are granted under are described in further detail in Note 6, Stock-Based Compensation Plans, to our Notes to Consolidated Financial Statements in Part IV, Item 15 of this Form 10-K.

Accounting for Income Taxes

Accounting for income taxes requires significant judgments in the development of estimates used in income tax calculations. Such judgments include, but are not limited to, the likelihood we would realize the benefits of net operating loss carryforwards and/or foreign tax credit carryforwards, the adequacy of valuation allowances, and the rates used to measure transactions with foreign subsidiaries. As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. The judgments and estimates used are subject to challenge by domestic and foreign taxing authorities.

We account for income taxes in accordance with ASC 740, Income Taxes. As part of our process of determining current tax liability, we exercise judgment in evaluating positions we have taken in our tax returns. We periodically assess our tax exposures and establish, or adjust, estimated unrecognized benefits for probable assessments by taxing authorities, including the Internal Revenue Service, and various foreign and state authorities. Such unrecognized tax benefits represent the estimated provision for income taxes expected to ultimately be paid. It is possible that either domestic or foreign taxing authorities could challenge those judgments or positions and draw conclusions that would cause us to incur tax liabilities in excess of, or realize benefits less than, those currently recorded. In addition, changes in the geographical mix or estimated amount of annual pretax income could impact our overall effective tax rate.

To the extent recovery of deferred tax assets is not more likely than not, we record a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized. Although we have considered future taxable income along with prudent and feasible tax planning strategies in assessing the need for a valuation allowance, if we should determine that we would not be able to realize all or part of our deferred tax assets in the future, an adjustment to deferred tax assets would be charged to income in the period any such determination was made. Likewise, in the event we are able to realize our deferred tax assets in the future in excess of the net recorded amount, an adjustment to deferred tax assets would increase income in the period any such determination was made.

New Accounting Standards Recently Adopted

For information related to recent accounting pronouncements and the impact of these pronouncements on our consolidated financial statements, see Note 1, Nature of Business and Summary of Significant Accounting Policies, to our Notes to Consolidated Financial Statements in Part IV, Item 15 of this Form 10-K.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Excluding the impact of changes in interest rates, inflationary pressures, and the uncertainty in the global financial markets, there have been no material changes to our market risk for the year ended December 31, 2023. We conduct business in all parts of the world and are thereby exposed to market risks related to fluctuations in foreign currency exchange rates. The U.S. dollar is the single largest currency in which our revenue contracts are denominated. Any decline in the value of local foreign currencies against the U.S. dollar results in our products and services being more expensive to a potential foreign customer. In those instances where our goods and services have already been sold, receivables may be more difficult to collect. Additionally, in jurisdictions where the revenue contracts are denominated in U.S. dollars and operating expenses are incurred in the local currency, any decline in the value of the U.S. dollar will have an unfavorable impact to operating margins. At times, we enter into revenue contracts that are denominated in the country’s local currency, primarily in Australia, Canada, the United Kingdom, other European countries, Brazil, India, and Singapore. This practice serves as a natural hedge to finance the local currency expenses incurred in those locations. We have not entered into any foreign currency hedging transactions. We do not purchase or hold any derivative financial instruments for speculation or arbitrage.

The primary objective of our cash investment policy is to preserve principal without significantly increasing risk. If we maintained similar cash investments for a period of one year based on our cash investments and interest rates at December 31, 2023, a hypothetical ten percent increase or decrease in effective interest rates would increase or decrease interest income by $0.1 million annually.

Table of Contents

We had approximately $1.0 billion of debt outstanding at December 31, 2023, with $643.7 million outstanding under our Credit Facility and $400.0 million in 2026 Notes. Our Credit Facility has a floating rate, which was 7.21% at December 31, 2023. Our 2026 Notes are fixed-rate long-term debt obligations with a 5.750% interest rate. A hypothetical ten percent increase or decrease in effective interest rates would increase or decrease interest expense related to the Credit Facility by approximately $4.6 million.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of our consolidated financial statements for external purposes in accordance with U.S. GAAP. Under the supervision of, and with the participation of our Chief Executive Officer and Chief Financial Officer, management assessed the effectiveness of internal control over financial reporting as of December 31, 2023.

Management based its assessment on criteria established in “Internal Control Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2023.

The effectiveness of our internal control over financial reporting as of December 31, 2023, has been audited by Deloitte & Touche, LLP, an independent registered public accounting firm, and Deloitte & Touche, LLP has issued an attestation report on our internal control over financial reporting.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) under the Exchange Act) during the quarter ended December 31, 2023, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of ACI Worldwide, Inc.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of ACI Worldwide, Inc. and subsidiaries (the “Company”) as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by 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, 2023, of the Company and our report dated February 29, 2024, 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 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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of ACI Worldwide, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of ACI Worldwide, Inc. and subsidiaries (the “Company”) as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2023, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 29, 2024, expressed an unqualified opinion on the Company’s internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue Recognition - Refer to Note 2 to the financial statements

The Company recognizes revenue upon transfer of control of promised products and/or services to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those products or services. The Company’s software license arrangements provide the customer with the right to use functional intellectual property (as it exists at the point in time at which the license is granted) for the duration of the contract term. Implementation, support, and other services are typically considered distinct performance obligations when sold with a software license.

Table of Contents

Significant judgment is exercised by the Company in determining revenue recognition for these customer arrangements, and includes the following:

•Determination of the term of a software license arrangement when early termination rights are provided to the customer.

•Determination of whether products and/or services are considered distinct performance obligations that should be accounted for separately.

•Determination of whether the financing component in a software licensing arrangement is significant and, if so, the discount rate used in calculating the significant financing component.

•Assessment of whether the extension of payment terms in a software licensing arrangement results in variable consideration and, if so, the amount to be included in the transaction price.

•Determination of the standalone selling price for each performance obligation, the amount allocated to each performance obligation and whether it depicts the amount that the Company expects to be entitled to in exchange for the related product and/or service. As the selling prices of the Company’s software licenses are highly variable, the Company estimates standalone selling price of its software licenses using the residual approach when the software license is sold with other services and observable standalone selling prices exist for the other services.

Given these factors, the related audit effort in evaluating management’s judgments in determining revenue recognition for software license arrangements was extensive and required a high degree of auditor judgment.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the Company’s accounting for software license arrangements included the following, among others:

•We tested the effectiveness of controls over the review of software license arrangements, including, among others, the determination of the contract term, identification of performance obligations, determination of significant financing component, estimation of variable consideration, and determination of standalone selling prices, including those controls over the determination that software license pricing is highly variable.

•We selected a sample of software license arrangements and performed the following, among others:

•Obtained contract source documents for each selection, including separate contracts or agreements that should be combined with the selected arrangement, and other documents that were part of the arrangement.

•Tested management’s determination of the contract term, identification of performance obligations, determination of significant financing component, estimation of variable consideration, and determination of standalone selling prices.

•Evaluated the reasonableness of the methodology and estimates used by management and the appropriateness of its revenue recognition conclusions for these key judgment areas.

•Tested the mathematical accuracy of management’s calculations of revenue and the associated timing of revenue recognized in the financial statements.

•We evaluated management’s determination that software license pricing is highly variable by obtaining management’s highly variable analysis and performing the following:

•Testing the completeness of management’s analysis by tracing a selection of known data points from an independent internal source into the highly variable analysis.

•Testing the accuracy of management’s analysis by selecting a sample of contracts from the highly variable analysis, obtaining the contract and price detail, and evaluating whether discounts were appropriately included in the analysis.

•Testing the mathematical accuracy of management’s calculation.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Nature of Business and Summary of Significant Accounting Policies

Nature of Business

ACI Worldwide, Inc., a Delaware corporation, and its subsidiaries (collectively referred to as “ACI” or the “Company”) develop, market, install, and support a broad line of software products and services primarily focused on facilitating electronic payments. In addition to its own products, the Company distributes or acts as a sales agent for software developed by third parties. These products and services are used principally by banks and intermediaries, merchants, and billers, both in domestic and international markets.

Consolidated Financial Statements

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated.

Capital Stock

The Company’s outstanding capital stock consists of a single class of common stock. Each share of common stock is entitled to one vote for each matter subject to a stockholder’s vote and to dividends, if and when declared by the board of directors (the “board”).

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions are affected by management’s application of accounting policies, as well as uncertainty in the current economic environment. Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company’s cash and cash equivalents includes holdings in checking, savings, money market, and overnight sweep accounts, all of which have daily maturities, as well as time deposits with maturities of three months or less at the date of purchase.

Other Current Liabilities

Other current liabilities include the following (in thousands):


	December 31,
	2023		2022
Vendor financed licenses	$	12,702	$	13,525
Operating lease liabilities	9,348		11,218
Accrued interest	9,172		9,067
Royalties payable	5,199		3,726
Other	45,823		65,109
Total other current liabilities	$	82,244	$	102,645

Settlement Assets and Liabilities

Individuals and businesses settle their obligations to the Company’s various Biller clients using credit or debit cards or via automated clearing house (“ACH”) payments. The Company creates a receivable for the amount due from the credit or debit card processor and an offsetting payable to the client. Upon confirmation that the funds have been received, the Company settles the obligation to the client. Due to timing, in some instances, the Company may (1) receive the funds into bank accounts controlled by and in the Company’s name that are not disbursed to its clients by the end of the day, resulting in a settlement deposit on the Company’s books and (2) disburse funds to its clients in advance of receiving funds from the credit or debit card processor, resulting in a net settlement receivable position.

Table of Contents

Off Balance Sheet Settlement Accounts

The Company also enters into agreements with certain Biller clients to process payment funds on their behalf. When an ACH or automated teller machine network payment transaction is processed, a transaction is initiated to withdraw funds from the designated source account and deposit them into a settlement account, which is a trust account maintained for the benefit of the Company’s clients. A simultaneous transaction is initiated to transfer funds from the settlement account to the intended destination account. These “back to back” transactions are designed to settle at the same time, usually overnight, such that the Company receives the funds from the source at the same time as it sends the funds to their destination. However, due to the transactions being with various financial institutions there may be timing differences that result in float balances. These funds are maintained in accounts for the benefit of the client which is separate from the Company’s corporate assets. As the Company does not take ownership of the funds, these settlement accounts are not included in the Company’s balance sheet. The Company is entitled to interest earned on the fund balances. The collection of interest on these settlement accounts is considered in the Company’s determination of its fee structure for clients and represents a portion of the payment for services performed by the Company. The amount of settlement funds as of December 31, 2023 and 2022, were $273.2 million and $328.7 million, respectively.

Property and Equipment

Property and equipment are stated at cost. Depreciation of these assets is generally computed using the straight-line method over their estimated useful lives based on asset class. As of December 31, 2023 and 2022, net property and equipment consisted of the following (in thousands):

Software

Software may be for internal use or for resale. Costs related to certain software, which is for resale, are capitalized in accordance with Accounting Standards Codification (“ASC”) 985-20, Costs of Software to be Sold, Leased, or Marketed, when the resulting product reaches technological feasibility. The Company generally determines technological feasibility when it has a detailed program design that takes product function, feature and technical requirements to their most detailed, logical form and is ready for coding. The Company does not typically capitalize costs related to software for resale as technological feasibility generally coincides with general availability of the software. The Company capitalizes the costs of software developed or obtained for internal use in accordance with ASC 350-40, Internal Use Software. The Company expenses all costs incurred during the preliminary project stage of its development and capitalizes the costs incurred during the application development stage. Costs incurred relating to upgrades and enhancements to the software are capitalized if it is determined that these upgrades or enhancements add additional functionality to the software. Costs incurred during the application development stage include purchased software licenses, implementation costs, consulting costs, and payroll-related costs for projects that qualify for capitalization. All other costs, primarily related to maintenance and minor software fixes, are expensed as incurred.

Amortization of software for resale is determined on a product-by-product basis and begins when the product is available for licensing to customers. The annual amortization is computed using the greater of (a) the ratio of current gross revenues to the total of current and future gross revenues expected to be derived from the software or (b) the straight-line method over the remaining estimated useful life of generally five to ten years, including the period being reported on. Due to competitive pressures, it may be possible that the estimates of future gross revenue or remaining estimated useful life of the software will be reduced significantly. As a result, the carrying amount of the software may be reduced accordingly. Amortization of internal-use software is generally computed using the straight-line method over estimated useful lives of three to eight years.

Business Combinations

The Company applies the provisions of ASC 805, Business Combinations, in the accounting for its acquisitions. It requires the Company to recognize separately from goodwill the assets acquired and the liabilities assumed at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred and the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date, its estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, it records adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements of operations.

Critical estimates in valuing certain intangible assets include but are not limited to future expected cash flows from customer relationships, covenants not to compete and acquired developed technologies, brand awareness and market position, as well as assumptions about the period of time the brand will continue to be used in our product portfolio, and discount rates. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates.

Other estimates associated with the accounting for acquisitions may change as additional information becomes available regarding the assets acquired and liabilities assumed.

Fair Value

ASC 820, Fair Value Measurements and Disclosures, (“ASC 820”) defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. ASC 820 establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

•Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

•Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

•Level 3 Inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

The fair value of the Company’s Credit Agreement approximates the carrying value due to the floating interest rate (Level 2 of the fair value hierarchy). The Company measures the fair value of its Senior Notes based on Level 2 inputs, which include quoted market prices and interest rate spreads of similar securities. The fair value of the Company’s 5.750% Senior Notes due 2026 (“2026 Notes”) was $398.5 million and $390.0 million as of December 31, 2023 and 2022, respectively.

The fair values of cash and cash equivalents approximate the carrying values due to the short period of time to maturity (Level 2 of the fair value hierarchy).

Goodwill and Other Intangibles

In accordance with ASC 350, Intangibles – Goodwill and Other, the Company assesses goodwill for impairment annually during the fourth quarter of its fiscal year using October 1 balances or when there is evidence that events or changes in circumstances indicate that the carrying amount of the asset may not be recovered. The Company evaluates goodwill at the reporting unit level using the discounted cash flow valuation model and allocates goodwill to these reporting units using a relative fair value approach. During this assessment, management relies on a number of factors, including operating results, business plans, and anticipated future cash flows. The Company has identified its reportable segments, Banks, Merchants, and Billers, as the reporting units. As of December 31, 2023, the Company's goodwill balance of $1.2 billion was allocated $671.7 million to Banks, $137.3 million to Merchants, and $417.0 million to Billers.

Table of Contents

The key assumptions used in the discounted cash flow valuation model include discount rates, growth rates, cash flow projections and terminal value rates. Discount rates, growth rates, and cash flow projections are the most sensitive and susceptible to change, as they require significant management judgment. Discount rates are determined by using a weighted average cost of capital (“WACC”). The WACC considers market and industry data as well as company-specific risk factors. Operational management, considering industry and company-specific historical and projected data, develops growth rates and cash flow projections for each reporting unit. Terminal value rate determination follows common methodology of capturing the present value of perpetual cash flow estimates beyond the last projected period, assuming a constant WACC and low, long-term growth rates. If, as per the quantitative test, the estimated fair value of the reporting unit is less than the carrying amount of the reporting unit, impairment is recognized for the difference, limited to the amount of goodwill recognized for the reporting unit. The calculated fair value substantially exceeded the current carrying value for all reporting units for all periods.

Other intangible assets, which include customer relationships and trademarks and trade names, are amortized using the straight-line method over periods ranging from four to 20 years. The Company reviews its other intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.

Equity Method Investment

In July 2019, the Company invested $18.3 million for a 30% non-controlling financial interest in a payment technology and services company in India. The Company accounted for this investment using the equity method in accordance with ASC 323, Investments - Equity Method and Joint Ventures. The Company records its share of earnings and losses in the investment on a one-quarter lag basis. Accordingly, the Company recorded an investment of $18.5 million and $17.9 million, which is included in other noncurrent assets in the consolidated balance sheet as of December 31, 2023 and 2022, respectively.

Impairment of Long-Lived Assets

The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset group may not be recoverable. An impairment loss is recorded if the sum of the future cash flows expected to result from the use of the asset (undiscounted and without interest charges) is less than the carrying amount of the asset. The amount of the impairment charge is measured based upon the fair value of the asset group.

Treasury Stock

The Company accounts for shares of its common stock that are repurchased without intent to retire as treasury stock. Such shares are recorded at cost and reflected separately on the consolidated balance sheets as a reduction of stockholders’ equity. The Company issues shares of treasury stock upon exercise of stock options, issuance of restricted share units, payment of earned performance shares, and for issuance of common stock pursuant to the Company’s employee stock purchase plan. For purposes of determining the cost of the treasury shares re-issued, the Company uses the average cost method.

Stock-Based Compensation Plans

In accordance with ASC 718, Compensation – Stock Compensation, ("ASC 718") the Company recognizes stock-based compensation expense for awards that are probable of vesting on a straight-line basis over the requisite service period of the award, which is generally the vesting term. Stock-based compensation expense is recorded in operating expenses depending on where the respective individual’s compensation is recorded. To determine the grant date fair value of total shareholder return awards (“TSRs”), a Monte Carlo simulation model was used. The assumptions utilized in the Monte Carlo simulation models, as well as the description of the plans the stock-based awards are granted under, are described in further detail in Note 6, Stock-Based Compensation Plans.

Translation of Foreign Currencies

The Company’s foreign subsidiaries typically use the local currency of the countries in which they are located as their functional currency. Their assets and liabilities are translated into U.S. dollars at the exchange rates in effect at the balance sheet date. Revenues and expenses are translated at the average exchange rates during the period. Translation gains and losses are reflected in the consolidated financial statements as a component of accumulated other comprehensive income (loss). Transaction gains and losses, including those related to intercompany accounts, that are not considered to be of a long-term investment nature are included in the determination of net income. Transaction gains and losses, including those related to intercompany accounts, that are considered to be of a long-term investment nature are reflected in the consolidated financial statements as a component of accumulated other comprehensive income (loss).

Income Taxes

The provision for income taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities. Deferred tax assets are reduced by a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized.

The Company periodically assesses its tax exposures and establishes, or adjusts, estimated unrecognized tax benefits for probable assessments by taxing authorities, including the Internal Revenue Service, and various foreign and state authorities. Such unrecognized tax benefits represent the estimated provision for income taxes expected to ultimately be paid.

Recently Issued Accounting Standards Not Yet Effective

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for annual periods beginning after December 15, 2023 and interim periods beginning after December 15, 2024, and early application is permitted. The Company is currently assessing the impact the adoption of ASU 2023-07 will have on its segment reporting disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this update will require disclosure of more disaggregated information about a reporting entity's effective tax rate reconciliation and income taxes paid. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, and early application is permitted for annual financial statements that have not yet been issued or made available for issuance. The Company is currently assessing the impact the adoption of ASU 2023-09 will have on its income tax disclosures.

2. Revenue

Revenue Recognition

In accordance with ASC 606, Revenue From Contracts With Customers, revenue is recognized upon transfer of control of promised products and/or services to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those products and services. Revenue is recognized net of any taxes collected from customers and subsequently remitted to governmental authorities.

Contract Combination. The Company may execute more than one contract or agreement with a single customer at or near the same time. The separate contracts or agreements may be viewed as one combined arrangement or separate agreements for revenue recognition purposes. In order to reach appropriate conclusions regarding whether such agreements should be combined, the Company evaluates whether the agreements were negotiated as a package with a single commercial objective, whether the amount of consideration to be paid in one agreement depends on the price and/or performance of another agreement, or whether the product(s) or services promised in the agreements represent a single performance obligation. The conclusions reached can impact the allocation of the transaction price to each performance obligation and the timing of revenue recognition related to those arrangements.

Software as a Service (“SaaS”) and Platform as a Service (“PaaS”) Arrangements. The Company’s SaaS-based and PaaS-based arrangements, including implementation, support and other services, represent a single promise to provide continuous access (i.e. a stand-ready performance obligation) to its software solutions and their processing capabilities in the form of a service through one of the Company’s data centers. As each day of providing access to the software solution(s) is substantially the same and the customer simultaneously receives and consumes the benefits as access is provided, the Company’s single promise under its SaaS-based and PaaS-based arrangements is comprised of a series of distinct service periods. The Company’s SaaS-based and PaaS-based arrangements may include fixed consideration, variable consideration, or a combination of the two. Fixed consideration is recognized over the term of the arrangement or longer if the fixed consideration relates to a material right. A material right would be a separate performance obligation. The Company estimates the stand-alone selling price for a material right by reference to the services expected to be provided and the corresponding expected consideration. Variable consideration in these arrangements is typically a function of transaction volume or another usage-based measure. Depending upon the structure of a particular arrangement, the Company: (1) allocates the variable amount to each distinct service period within the series and recognizes revenue as each distinct service period is performed, (2) estimates total variable consideration at contract inception (giving consideration to any constraints that may apply and updating the estimates as new information becomes available) and recognizes the total transaction price over the period to which it relates, or (3) applies the ‘right to invoice’ practical expedient and recognizes revenue based on the amount invoiced to the customer during the period.

Table of Contents

License Arrangements. The Company’s software license arrangements provide the customer with the right to use functional intellectual property (as it exists at the point in time at which the license is granted) for the duration of the contract term. Implementation, support, and other services are typically considered distinct performance obligations when sold with a software license.

Payment terms for the Company’s software license arrangements generally include fixed license and capacity fees that are payable up front or over time. These arrangements may also include incremental usage-based fees that are payable when the customer exceeds its contracted license capacity limits. The Company accounts for capacity overages as a usage-based royalty that is recognized when the usage occurs.

When a software license arrangement contains payment terms that are extended beyond one year, a significant financing component may exist. The significant financing component is calculated as the difference between the stated value and present value of the software license fees and is recognized as interest income over the extended payment period. The total fixed software license fee net of the significant financing component is recognized as revenue at the point in time when the software is transferred to the customer.

For those software license arrangements that include customer-specific acceptance provisions, such provisions are generally presumed to be substantive and the Company does not recognize revenue until the earlier of the receipt of a written customer acceptance, objective demonstration that the delivered product meets the customer-specific acceptance criteria, or the expiration of the acceptance period. The Company recognizes revenues on such arrangements upon the earlier of receipt of written acceptance or the first production use of the software by the customer.

For software license arrangements in which the Company acts as a distributor of another company’s product, and in certain circumstances, modifies or enhances the product, revenues are recorded on a gross basis. These include arrangements in which the Company takes control of the products and is responsible for providing the product or service. For software license arrangements in which the Company acts as a sales agent for another company’s product, revenues are recorded on a net basis. These include arrangements in which the Company does not take control of products and is not responsible for providing the product or service.

For software license arrangements in which the Company utilizes a third-party distributor or sales agent, the Company recognizes revenue upon transfer of control of the software license(s) to the third-party distributor or sales agent.

The Company’s software license arrangements typically provide the customer with a standard 90-day assurance-type warranty. These warranties do not represent an additional performance obligation as services beyond assuring that the software license complies with agreed-upon specifications are not provided.

Software license arrangements typically include an initial post contract customer support (maintenance or “PCS”) term of one year with subsequent renewals for additional years within the initial license period. The Company’s promise to those customers who elect to purchase PCS represents a stand-ready performance obligation that is distinct from the license performance obligation and recognized over the PCS term.

The Company also provides various professional services to customers with software licenses. These include project management, software implementation, and software modification services. Revenues from arrangements to provide professional services are generally distinct from the other promises in the contract(s) and are recognized as the related services are performed. Consideration received under these arrangements is either fixed fee or on a time-and-materials basis, which represents variable consideration that must be estimated using the most likely amount based on the range of hours expected to be incurred in providing the services.

The Company estimates the stand-alone selling price (“SSP”) for maintenance and professional services based on observable stand-alone sales. The Company applies the residual approach to estimate the SSP for software licenses.

Refer to Note 10, Segment Information, for further details, including disaggregation of revenue based on primary solution category and geographic location.

Significant Judgments

The Company applies judgment in determining the customer’s ability and intention to pay, which is based on a variety of factors including the customer’s historical payment experience or, in the case of a new customer, published credit and financial information.

The Company also applies judgment in determining the term of an arrangement when early termination rights are provided to the customer.

The Company’s software license arrangements with its customers often include multiple promises to transfer licensed software products and services. Determining whether the products and/or services are distinct performance obligations that should be accounted for separately may require significant judgment.

The Company’s SaaS and PaaS arrangements may include variable consideration in the form of usage-based fees. If the arrangement that includes variable consideration in the form of usage-based fees does not meet the allocation exception for variable consideration, the Company estimates the amount of variable consideration at the outset of the arrangement using either the expected value or most likely amount method, depending on the specifics of each arrangement. These estimates are constrained to the extent that it is probable that a significant reversal of incremental revenue will not occur and are updated each reporting period as additional information becomes available.

Judgment is used in determining: (1) whether the financing component in a software license agreement is significant and, if so, (2) the discount rate used in calculating the significant financing component. The Company assesses the significance of the financing component based on the ratio of license fees paid over time to total license fees. If determined to be significant, the financing component is calculated using a rate that discounts the license fees to the cash selling price.

Judgment is also used in assessing whether the extension of payment terms in a software license arrangement results in variable consideration and, if so, the amount to be included in the transaction price. The Company applies the portfolio approach to estimate the amount of variable consideration in these arrangements using the most likely amount method that is based on the Company’s historical collection experience under similar arrangements.

Significant judgment is required to determine the SSP for each performance obligation, the amount allocated to each performance obligation and whether it depicts the amount that the Company expects to be entitled to in exchange for the related product and/or service. As the selling prices of the Company’s software licenses are highly variable, the Company estimates SSP of its software licenses using the residual approach when the software license is sold with other services and observable SSPs exist for the other services. The Company uses a range of amounts to estimate SSP for maintenance and services. These ranges are based on stand-alone sales and vary based on the type of service and geographic region. If the SSP of a performance obligation is not directly observable, the Company will maximize observable inputs to determine its SSP.

Contract Balances

Timing of revenue recognition may differ from the timing of invoicing to customers. The Company records an accrued receivable when revenue is recognized prior to invoicing and the Company’s right to consideration only requires the passage of time, or deferred revenue when revenue is recognized subsequent to invoicing.

Total receivables represent amounts billed and amounts earned that are to be billed in the future (i.e., accrued receivables). Included in accrued receivables are services and SaaS and PaaS revenues earned in the current period but billed in the following period and amounts due under multi-year software license arrangements with extended payment terms for which the Company has an unconditional right to invoice and receive payment subsequent to invoicing.

Table of Contents

Total receivables, net is comprised of the following (in thousands):

Revenue allocated to remaining performance obligations represents contracted revenue that will be recognized in future periods, which is comprised of deferred revenue and amounts that will be invoiced and recognized as revenue in future periods. This does not include:

•Revenue that will be recognized in future periods from capacity overages that are accounted for as a usage-based royalty.

•SaaS and PaaS revenue from variable consideration that will be recognized in accordance with the ‘right to invoice’ practical expedient or meets the allocation objective.

Revenue allocated to remaining performance obligations was $665.6 million as of December 31, 2023, of which the Company expects to recognize approximately 50% over the next 12 months and the remainder thereafter.

During the year ended December 31, 2023, the revenue recognized by the Company from performance obligations satisfied in previous periods was $79.0 million.

Costs to Obtain and Fulfill a Contract

The Company accounts for costs to obtain and fulfill its contracts in accordance with ASC 340-40.

The Company capitalizes certain of its sales commissions that meet the definition of incremental costs of obtaining a contract and for which the amortization period is greater than one year. The costs associated with those sales commissions are capitalized during the period in which the Company becomes obligated to pay the commissions and are amortized over the period in which the related products or services are transferred to the customer. As of December 31, 2023 and 2022, $3.3 million and $1.5 million of these costs are included in other current assets, respectively, and $13.9 million and $14.5 million of these costs are included in other noncurrent assets, respectively, on the consolidated balance sheets. During the years ended December 31, 2023 and 2022, the Company recognized $8.7 million and $8.3 million of sales commission expense, respectively, related to the amortization of these costs, which is included in selling and marketing expense on the consolidated statements of operations.

The Company capitalizes costs incurred to fulfill its contracts that: (1) relate directly to the arrangement, (2) are expected to generate resources that will be used to satisfy the Company’s performance obligation under the arrangement, and (3) are expected to be recovered through revenue generated under the arrangement. Contract fulfillment costs are expensed as the Company transfers the related services to the customer. As of both December 31, 2023 and 2022, less than $0.1 million of these costs are included in other current assets, and $9.7 million of these costs are included in other noncurrent assets on the consolidated balance sheets. The amounts capitalized primarily relate to direct costs that enhance resources under the Company’s SaaS and PaaS arrangements. During the years ended December 31, 2023 and 2022, the Company recognized $3.6 million and $3.1 million of expense, respectively, related to the amortization of these costs, which is included in cost of revenue on the consolidated statements of operations.

3. Divestiture

Corporate Online Banking Solutions

On June 7, 2022, the Company announced a definitive agreement to divest its corporate online banking solutions related assets and liabilities to One Equity Partners ("OEP") for $100.0 million, and a net working capital adjustment. The sale included employees and customer contracts as well as technology assets and intellectual property and closed on September 1, 2022.

For the year ended December 31, 2022, the Company recognized a gain of $38.5 million on the sale, which is recorded in other, net on the consolidated statements of operations. During the year ended December 31, 2023, the Company recognized a loss for the final post-closing adjustment pursuant to the definitive agreement of $0.5 million, which is recorded in other, net on the consolidated statements of operations.

4. Debt

As of December 31, 2023, the Company had $124.0 million, $519.7 million, and $400.0 million outstanding under its Revolving Credit Facility, Term Loans, and Senior Notes, respectively, with up to $373.9 million of unused borrowings under the Revolving Credit Facility portion of the Credit Agreement, as amended, and up to $2.1 million of unused borrowings under the Letter of Credit agreements. The amount of unused borrowings actually available varies in accordance with the terms of the agreement.

Credit Agreement

On April 5, 2019, the Company (and its wholly-owned subsidiaries, ACI Worldwide Corp. and ACI Payments, Inc. entered into the Second Amended and Restated Credit Agreement (the “Credit Agreement”), with the lenders, and Bank of America, N.A., as administrative agent for the lenders, to amend and restate the Company's existing agreement, as amended, dated February 24, 2017. The amended Credit Agreement permitted the Company to borrow up to $500.0 million in the form of an additional senior secured term loan; extended the revolver and the existing term loan maturity date from February 24, 2022, to April 5, 2024; increased the maximum consolidated senior secured net leverage ratio covenant from 3.50:1.00 to 3.75:1.00; and increased the maximum consolidated total net leverage ratio covenant from 4.25:1.00 to 5.00:1.00, with subsequent decreases occurring every three quarters thereafter for a specified period of time; among other things.

On May 5, 2022, the Company and Bank of America entered into the LIBOR Transition Amendment (the "Amendment") that replaced the LIBOR reference rate with the Secured Overnight Financing Rate ("SOFR") reference rate. No other terms or conditions of the Credit Agreement were changed as a result of the Amendment.

On April 28, 2023, the Company and Bank of America entered into the 2023 Extension Amendment to extend the term of the Credit Facility one year to April 5, 2025. All other terms remained the same.

The Credit Agreement consists of (a) a five-year $500.0 million senior secured revolving credit facility (the “Revolving Credit Facility”), which includes sublimits for (1) the issuance of standby letters of credit and (2) swingline loans, (b) a five-year $279.0 million senior secured term loan facility (the “Initial Term Loan”) and (c) a five-year $500.0 million Delayed Draw Term Loan (together with the Initial Term Loan, the "Term Loans", and together with the Initial Term Loan and the Revolving Credit Facility, the “Credit Facility”). The Credit Agreement also allows the Company to request optional incremental term loans and increases in the revolving commitment.

At the Company’s option, borrowings under the Credit Facility bear interest at an annual rate equal to either (a) a base rate determined by reference to the highest of (1) the annual interest rate publicly announced by the administrative agent as its Prime Rate, (2) the federal funds effective rate plus 1/2 of 1% or (3) SOFR rate determined by reference to the costs of funds for U.S. dollar deposits for a one-month interest period, adjusted for certain additional costs plus 1% or (b) SOFR rate determined by reference to the costs of funds for U.S. dollar deposits for the interest period relevant to such borrowings, adjusted for certain additional costs plus an applicable margin. Based on the calculation of the applicable consolidated total leverage ratio, the applicable margin for borrowings under the Credit Facility is between 0.25% to 1.25% with respect to base rate borrowings and between 1.25% and 2.25% with respect to SOFR rate borrowings. Interest is due and payable monthly. The interest rate in effect for the Credit Facility as of December 31, 2023, was 7.21%.

The Company is also required to pay (a) a commitment fee related to the unutilized commitments under the Revolving Credit Facility, payable quarterly in arrears, (b) letter of credit fees on the maximum amount available to be drawn under all outstanding letters of credit in an amount equal to the applicable margin on SOFR rate borrowings under the Revolving Credit Facility on an annual basis, payable quarterly in arrears, and (c) customary fronting fees for the issuance of letters of credit fees and agency fees.

The Company’s obligations under the Credit Facility and cash management arrangements entered into with lenders under the Credit Facility (or affiliates thereof) and the obligations of the subsidiary guarantors are secured by first-priority security interests in substantially all assets of the Company and any guarantor, including 100% of the capital stock of ACI Worldwide Corp. and each domestic subsidiary of the Company, each domestic subsidiary of any guarantor, and 65% of the voting capital stock of each foreign subsidiary of the Company that is directly owned by the Company or a guarantor, in each case subject to certain exclusions set forth in the credit documentation governing the Credit Facility. The collateral agreement of the Credit Agreement, as amended, released the lien on certain assets of ACI Payments, Inc., our electronic bill presentment and payment affiliate, to allow ACI Payments, Inc. to comply with certain eligible securities and unencumbered asset requirements related to money transmitter or transfer license rules and regulations.

The Credit Agreement contains a number of covenants that, among other things and subject to certain exceptions, restrict the Company’s and its subsidiaries' ability to: create, incur, assume or suffer to exist any additional indebtedness; create, incur, assume or suffer to exist any liens; enter into agreements and other arrangements that include negative pledge clauses; pay dividends on capital stock or redeem, repurchase or retire capital stock or subordinated indebtedness; create restrictions on the payment of dividends or other distributions by subsidiaries; make investments, loans, advances and acquisitions; merge, consolidate or enter into any similar combination or sell assets, including equity interests of the subsidiaries; enter into sale and leaseback transactions; directly or indirectly engage in transactions with affiliates; alter in any material respect the character or conduct of the business; enter into amendments of or waivers under subordinated indebtedness, organizational documents and certain other material agreements; and hold certain assets and incur certain liabilities.

On February 26, 2024, the Company entered into a Refinance Amendment (the “Amendment”) to the Second Amended and Restated Credit Agreement, dated as of April 5, 2019 (as amended, restated, supplemented or otherwise modified from time to time, including by the Amendment, the “Credit Agreement”) with ACI Worldwide Corp and ACI Payments, Inc. as co-borrowers, the lenders, and Bank of America N.A, as administrative agent and lender. The Amendment, among other things, (i) provides a senior secured term loan facility in an aggregate principal amount of $500 million, (ii) provides a senior secured revolving credit facility in an aggregate principal amount of $600 million, and (iii) extends the maturity date of the Facilities to February 26, 2029. The proceeds of the borrowings under the Amendment, together with cash on hand, were used to refinance all outstanding borrowings and replace all existing revolving commitments under the Credit Agreement immediately prior to the date of the Amendment and will be used to provide ongoing working capital and for other general corporate purposes.

Letters of Credit

From time to time the Company enters into standby letters of credit under the terms of the Credit Agreement. These letters of credit typically have one-year terms and may include auto-renewal terms without notice of intent to terminate the agreement. As of December 31, 2023, the Company had three letter of credit agreements outstanding for a total of $2.1 million.

The letters of credit reduce the maximum available borrowings under the Revolving Credit Facility to $497.9 million. Upon expiration of the letters of credit, maximum borrowings would return to $500.0 million.

Senior Notes

On August 21, 2018, the Company completed a $400.0 million offering of the 2026 Notes at an issue price of 100% of the principal amount in a private placement for resale to qualified institutional buyers. The 2026 Notes bear interest at an annual rate of 5.750%, payable semi-annually in arrears on February 15 and August 15 of each year, which commenced on February 15, 2019. The 2026 Notes will mature on August 15, 2026.

Overdraft Facility

In 2019, the Company and ACI Payments, Inc. entered in to an uncommitted overdraft facility with Bank of America, N.A. The overdraft facility bears interest at the federal funds effective rate plus 2.25% based on the Company’s average outstanding balance and the frequency in which overdrafts occur. The overdraft facility acts as a secured loan under the terms of the Credit Agreement to provide an additional funding mechanism for timing differences that can occur in the bill payment settlement process. Amounts outstanding on the overdraft facility are included in other current liabilities in the consolidated balance sheet. As of December 31, 2023, there was $75.0 million available and no amount outstanding on the overdraft facility. As of December 31, 2022, there was no amount outstanding on the overdraft facility.

6. Stock-Based Compensation Plans

Employee Stock Purchase Plan

On April 6, 2017, the board approved the 2017 Employee Stock Purchase Plan (“2017 ESPP”), which was approved by shareholders at the 2017 Annual Shareholder meeting. The 2017 ESPP provides employees with an opportunity to purchase shares of the Company’s common stock. Under the Company’s 2017 ESPP, a total of 3,000,000 shares of the Company’s common stock have been reserved for issuance to eligible employees. Participating employees are permitted to designate up to the lesser of $25,000 or 10% of their annual base compensation for the purchase of common stock under the ESPP. Purchases under the ESPP are made one calendar month after the end of each fiscal quarter. The price for shares of common stock purchased under the ESPP is 85% of the stock’s fair market value on the last business day of the three-month participation period.

Additionally, the discount offered pursuant to the Company’s ESPP discussed above is 15%, which exceeds the 5% non-compensatory guideline in ASC 718 and exceeds the Company’s estimated cost of raising capital. Consequently, the entire 15% discount to employees is deemed to be compensatory for purposes of calculating expense using a fair value method. Compensation expense related to the ESPP for the years ended December 31, 2023, 2022, and 2021, was approximately $0.5 million, $0.6 million, and $0.6 million, respectively.

Stock Incentive Plans – Active Plans

2020 Equity and Incentive Compensation Plan

On June 9, 2020, upon recommendation of the board, stockholders approved the ACI Worldwide, Inc. 2020 Equity and Incentive Compensation Plan (the “2020 Plan”). The 2020 Plan authorizes the board to provide for equity-based compensation in the form of stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units, dividend equivalents, and certain other awards, including those denominated or payable in, or otherwise based on, the Company’s common stock ("awards"). The purpose of the 2020 Plan is to provide incentives and rewards for service and/or performance by providing awards to non-employee directors, officers, other employees, and certain consultants and other service providers of the Company and its subsidiaries. Following the approval of the 2020 Plan, the 2016 Equity and Performance Incentive Plan (the “2016 Incentive Plan”) was terminated. Termination of the 2016 Incentive Plan did not affect any equity awards outstanding under the 2016 Incentive Plan.

Subject to adjustment and share counting rules as described in the 2020 Plan, a total of 6,658,754 shares of common stock are available for awards granted under the 2020 Plan. Shares underlying certain awards under the 2020 Plan, the Company’s 2005 Equity and Performance Incentive Plan (the "2005 Incentive Plan"), and the 2016 Incentive Plan (each including as amended or amended and restated) that are cancelled or forfeited, expire, are settled for cash, or are unearned after June 9, 2020, will again be available under the 2020 Plan.

The board generally will be able to amend the 2020 Plan, subject to stockholder approval in certain circumstances, as described in the 2020 Plan.

2016 Equity and Performance Incentive Plan

The Company's 2016 Incentive Plan provided for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock awards, performance awards, and other awards. The 2016 Incentive Plan was adopted by the stockholders on June 14, 2016. Following the adoption of the 2016 Incentive Plan, the 2005 Incentive Plan was terminated. Subject to adjustment in certain circumstances, the maximum number of shares of common stock that was issued or transferred in connection with awards granted under the 2016 Incentive Plan was the sum of (i) 8,000,000 shares of common stock and (ii) any shares of common stock that were represented by options previously granted under the 2005 Incentive Plan which were subsequently forfeited, expired, or cancelled without delivery of common stock or which resulted in the forfeiture or relinquishment of common stock back to the Company.

2005 Equity and Performance Incentive Plan

The Company's 2005 Incentive Plan, as amended, under which shares of the Company’s common stock were reserved for issuance to eligible employees or non-employee directors of the Company. The 2005 Incentive Plan provided for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock awards, performance awards, and other awards. The maximum number of shares of the Company’s common stock that was issued or transferred in connection with awards granted under the 2005 Incentive Plan was the sum of (i) 23,250,000 shares and (ii) any shares represented by outstanding options that had been granted under designated terminated stock option plans that were subsequently forfeited, expired, or are cancelled without delivery of the Company’s common stock.

Stock Options

Stock options granted pursuant to the Company's incentive plans were granted at an exercise price not less than the market value per share of the Company’s common stock on the date of grant. The term of the outstanding options may not exceed ten years nor be less than one year. Vesting of options is determined by the compensation committee of the board and the administrator of the respective plan and can vary based upon the individual award agreements. In addition, outstanding options do not have dividend equivalent rights associated with them.

A summary of stock option activity is as follows:


	Number of Shares	Weighted Average Exercise Price ($)		Weighted Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value of In-the-Money Options ($)
Outstanding, December 31, 2022	1,221,219	$	19.00
Exercised	(343,093)	19.60

Expired	(4,614)	19.63
Outstanding, December 31, 2023	873,512	$	18.76	1.98	$	10,345,792
Exercisable, December 31, 2023	873,512	$	18.76	1.98	$	10,345,792

The Company did not grant stock options during the years ended December 31, 2023, 2022, and 2021. The total intrinsic value of stock options exercised during the years ended December 31, 2023, 2022, and 2021, was $2.1 million, $2.9 million, and $11.4 million, respectively.

Long-term Incentive Program Performance Share Awards

During the year ended December 31, 2017, pursuant to the Company’s 2016 Incentive Plan, the Company granted long-term incentive program performance share awards (“LTIP performance shares”). These LTIP performance shares were earned based upon the achievement, over a specified period that must not be less than one year and was typically a three-year performance period, of performance goals related to (i) the compound annual growth over the performance period in the sales for the Company as determined by the Company, and (ii) the cumulative operating income or EBITDA over the performance period as determined by the Company. Up to 200% of the LTIP performance shares could be earned upon achievement of performance goals equal to or exceeding the maximum target levels for the performance goals over the performance period. On a quarterly basis, management evaluated the probability that the threshold performance goals would be achieved, if at all, and the anticipated level of attainment to determine the amount of compensation expense to record in the consolidated financial statements.

During the year ended December 31, 2021, the Company modified the performance target for the remaining outstanding long-term incentive program performance shares in consideration of the impact of the COVID-19 pandemic, resulting in additional stock-based compensation expense of approximately $0.4 million. There are no LTIP performance shares outstanding as of December 31, 2023.

Performance Share Awards

During the years ended December 31, 2023, 2022, and 2021, pursuant to the 2020 Plan and 2016 Incentive Plan, the Company granted performance share awards with a total shareholder return component ("TSRs"). For 2023, performance awards granted are earned, if at all, based upon achievement, over a specified period that must not be less than one year and is typically a three-year performance period, of performance goals related to (i) net revenue growth and (ii) net adjusted EBITDA margin over the performance period as determined by the Company with a total shareholder return multiplier up to plus or minus 20%. Up to 200% of the performance shares could be earned upon achievement of the performance goals, including the multiplier. For 2022 and 2021, the Company granted performance shares that are earned, if at all, based upon the Company’s total shareholder return as compared to a group of peer companies over a three-year performance period. The award payout can range from 0% to 200%. To determine the grant date fair value of the TSRs, a Monte Carlo simulation model is used. The Company recognizes compensation expense for the TSRs over the performance period based on the grant date fair value.

A summary of nonvested TSRs is as follows:


	Number of Shares	Weighted Average Grant Date Fair Value
Nonvested as of December 31, 2022	1,011,881	$	39.21
Granted	233,404	26.94

Forfeited	(144,474)	39.54
Change in payout rate	(427,685)	30.01
Nonvested as of December 31, 2023	673,126	$	40.73

During the year ended December 31, 2023, the TSRs granted in 2020 were earned by the employees. However, the performance goals were not met and no shares were issued.

The fair value of TSRs granted during the years ended December 31, 2023, 2022, and 2021, were estimated on the date of grant using the Monte Carlo simulation model, acceptable under ASC 718, using the following weighted-average assumptions:


	Years Ended December 31,
	2023		2022		2021
Expected life (years)	2.9		3.1		2.8
Risk-free interest rate	3.6	%	1.5	%	0.3	%
Volatility	37.1	%	40.0	%	41.2	%
Expected dividend yield	—		—		—

Restricted Share Units

During the years ended December 31, 2023, 2022, and 2021, pursuant to the 2020 Plan and the 2016 Incentive Plan, the Company granted restricted share unit awards (“RSUs”). RSUs generally have requisite service periods of three years and may vest 100% upon the three-year anniversary or in equal increments quarterly or annually. RSUs granted to the board vest one year from grant or as of the next annual shareholders meeting, whichever is earlier. Under each arrangement, RSUs are issued without direct cost to the recipient on the vesting date. The Company estimates the fair value of the RSUs based upon the market price of the Company’s stock on the date of grant. The Company recognizes compensation expense for RSUs on a straight-line basis over the requisite service period.

A summary of nonvested RSUs is as follows:


	Number of Shares	Weighted Average Grant Date Fair Value
Nonvested as of December 31, 2022	1,184,024	$	30.73
Granted	1,532,978	24.87
Vested	(666,026)	28.37
Forfeited	(476,093)	28.15
Nonvested as of December 31, 2023	1,574,883	$	26.81

During the year ended December 31, 2023, a total of 666,026 RSUs vested. The Company withheld 201,634 of those shares to pay the employees’ portion of the minimum payroll withholding taxes.

As of December 31, 2023, there was unrecognized compensation expense of $32.2 million related to RSUs and $7.8 million related to TSRs, which the Company expects to recognize over a weighted average period of 2.1 years and 1.7 years, respectively.

The Company recorded stock-based compensation expense recognized under ASC 718 during the years ended December 31, 2023, 2022, and 2021, of $24.5 million, $29.8 million, and $27.2 million, respectively, with corresponding tax benefits of $4.5 million, $4.5 million, and $3.9 million, respectively.

7. Common Stock and Treasury Stock

In 2005, the board approved a stock repurchase program authorizing the Company, as market and business conditions warrant, to acquire its common stock and periodically authorizes additional funds for the program. In February 2023, the board approved the repurchase of the Company's common stock of up to $200.0 million, in place of the remaining purchase amounts previously authorized.

The Company repurchased 939,567 shares for $27.6 million under the program for the year ended December 31, 2023. Under the program to date, the Company has repurchased 58,921,300 shares for approximately $953.8 million. As of December 31, 2023, the maximum remaining amount authorized for purchase under the stock repurchase program was $172.4 million.

Subsequent to December 31, 2023, the Company has repurchased additional shares under the repurchase program.

In 2006, the Company began to issue shares of treasury stock upon exercise of stock options, payment of earned performance shares (LTIP performance shares and TSRs), vesting of RSUs, and for issuances of common stock pursuant to the Company’s ESPP. Treasury shares issued by award type are as follows:


	Years Ended December 31,
	2023	2022	2021
Stock options	343,093	406,230	546,192
LTIP performance shares	—	—	10,457
TSRs	—	212,210	782,588
RSUs	666,026	534,759	522,618
ESPP	140,992	145,909	120,937
Total treasury shares issued	1,150,111	1,299,108	1,982,792

8. Earnings Per Share

Basic earnings per share is computed in accordance with ASC 260, Earnings per Share, based on weighted average outstanding common shares. Diluted earnings per share is computed based on basic weighted average outstanding common shares adjusted for the dilutive effect of stock options, RSUs, and certain contingently issuable shares for which performance targets have been achieved.

The following table reconciles the weighted average share amounts used to compute both basic and diluted earnings per share (in thousands):


	Years Ended December 31,
	2023	2022	2021
Weighted average shares outstanding:
Basic weighted average shares outstanding	108,497	113,700	117,407
Add: Dilutive effect of stock options, RSUs, and contingently issuable shares	360	538	1,240
Diluted weighted average shares outstanding	108,857	114,238	118,647

The diluted earnings per share computation excludes 1.3 million, 1.9 million, and 1.3 million options to purchase shares, RSUs, and contingently issuable shares during the years ended December 31, 2023, 2022, and 2021, respectively, as their effect would be anti-dilutive.

Common stock outstanding as of December 31, 2023 and 2022, was 108,077,738 and 108,068,828, respectively.

9. Other, Net

Other, net is primarily comprised of foreign currency transaction gains and losses and, for the year ended December 31, 2022, the $38.5 million gain on the divestiture. Other, net was $8.5 million of expense, $43.4 million of income, and $1.3 million of expense for the years ended December 31, 2023, 2022, and 2021, respectively.

10. Segment Information

The Company reports financial performance based on its operating segments, Banks, Merchants, and Billers, and analyzes Segment Adjusted EBITDA as a measure of segment profitability.

Revenue is attributed to the reportable segments based upon customer. Expenses are attributed to the reportable segments in one of three methods: (1) direct costs of the segment, (2) labor costs that can be attributed based upon time tracking for individual projects, or (3) costs that are allocated. Allocated costs are generally marketing and sales related activities.

Segment Adjusted EBITDA is the measure reported to the CODM for purposes of making decisions on allocating resources and assessing the performance of the Company’s segments, and, therefore, Segment Adjusted EBITDA is presented in conformity with ASC 280, Segment Reporting. Segment Adjusted EBITDA is defined as earnings (loss) from operations before interest, income tax expense (benefit), depreciation and amortization (“EBITDA”) adjusted to exclude net other income (expense).

Corporate and unallocated expenses includes global facilities and information technology costs and long-term product roadmap expenses in addition to corporate overhead costs that are not allocated to reportable segments. The overhead costs relate to human resources, finance, legal, accounting, and merger and acquisition activity. These costs along with depreciation and amortization and stock-based compensation are not considered when management evaluates segment performance.

The deferred tax asset and liabilities disclosure above reflects a $6.8 million deferred interest reclass for the year ended December 31, 2022. Prior year reported $6.8 million related to deferred interest as Other within the deferred tax asset section. The amount is now reported separately within the deferred tax asset section.

In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company considers projected future taxable income, carryback opportunities, and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods which the deferred tax assets are deductible, the Company believes it is more likely than not that it will realize the benefits of these deductible differences, net of the valuation allowances recorded.

At December 31, 2023, the Company had domestic federal tax net operating losses (“NOLs”) of $47.9 million, of which $2.9 million may be utilized over an indefinite life, with the remainder beginning to expire in 2024. The Company had deferred tax assets equal to $0.9 million related to domestic state tax NOLs which will begin to expire in 2024. The Company did not have any valuation allowance against the federal tax NOLs but had provided a $0.5 million valuation allowance against the deferred tax asset associated with the state NOLs. The Company had foreign tax NOLs of $16.7 million, of which $16.5 million may be utilized over an indefinite life, with the remainder expiring over the next five years. The Company did not have any valuation allowance against the deferred tax asset associated with the foreign NOLs.

The Company had U.S. foreign tax credit carryforwards at December 31, 2023, of $2.2 million, for which a $2.2 million valuation allowance had been provided. The U.S. foreign tax credits will begin to expire in 2028. The Company had foreign tax credit carryforwards in other foreign jurisdictions at December 31, 2023, of $3.3 million, of which $1.0 million may be utilized over an indefinite life, with the remainder expiring over the next seven years. The Company had provided a $1.0 million valuation allowance against the tax benefit associated with these foreign credits. The Company also had domestic federal general business tax credit carryforwards at December 31, 2023, of $27.4 million, which will expire in 2033 and state general business tax credit carryforwards of $0.6 million, which will begin to expire in 2024.

The Company did not provide deferred taxes on $41.5 million of unremitted earnings of its Indian subsidiaries that are considered permanently reinvested. The company did not estimate the deferred tax liability on these earnings as such estimation is not practicable to determine or is immaterial to the financial statements. As of December 31, 2023, deferred taxes for non-United States withholding and other taxes were provided on $23.4 million of unremitted earnings of non-United States subsidiaries that may be remitted to the United States. As of December 31, 2023 and 2022, the Company recorded a deferred tax liability of $0.6 million and $1.3 million, respectively, related to these non-United States earnings that may be remitted.

The unrecognized tax benefit at December 31, 2023 and 2022, was $20.9 million and $26.4 million, respectively, of which $10.5 million and $19.9 million, respectively, are included in other noncurrent liabilities in the consolidated balance sheets. Of the total unrecognized tax benefit amounts at December 31, 2023 and 2022, $20.1 million and $25.0 million, respectively, represent the net unrecognized tax benefits that, if recognized, would favorably impact the effective income tax rate in the respective years.

A reconciliation of the beginning and ending amount of unrecognized tax benefits for the years ended December 31 is as follows (in thousands):


	2023		2022		2021
Balance of unrecognized tax benefits at beginning of year	$	26,408	$	24,510	$	24,310
Increases for tax positions of prior years	1,568		2,349		1,533
Decreases for tax positions of prior years	(6,560)		(3,659)		(65)

Balance of unrecognized tax benefits at end of year	$	20,889	$	26,408	$	24,510

On July 21, 2023, the Internal Revenue Service (“IRS”) issued Notice 2023-55 providing guidance to taxpayers in determining whether a foreign tax is eligible for a U.S. foreign tax credit for tax years 2022 and 2023 effectively delaying the application of an unfavorable foreign tax credit regulation until 2024. As a result of this guidance, the Company recorded a tax benefit of $6.0 million in the fiscal third quarter of 2023.

The Company files income tax returns in the U.S. federal jurisdiction, various state and local jurisdictions, and many foreign jurisdictions. The United States, Ireland, and the United Kingdom are the main taxing jurisdictions in which the Company operates. The years open for audit vary depending on the tax jurisdiction. In the United States, the Company’s federal tax return for years following 2019 are open for audit. In the foreign jurisdictions, the tax returns open for audit generally vary by jurisdiction between 2006 and 2022.

The Company has been notified by the U.S. Internal Revenue Service that their 2021 federal tax return has been selected to be examined. The Company’s Indian income tax returns covering fiscal years ended March 31, 2005, 2014, 2016, 2018, and 2020 are under audit by the Indian tax authority. Other foreign subsidiaries could face challenges from various foreign tax authorities. It is not certain that the local authorities will accept the Company’s tax positions. The Company believes its tax positions comply with applicable tax law and intends to vigorously defend its positions. However, differing positions on certain issues could be upheld by tax authorities, which could adversely affect the Company’s financial condition and results of operations.

The Company believes it is reasonably possible that the total amount of unrecognized tax benefits will decrease within the next 12 months by approximately $2.2 million due to the settlement of various audits and the expiration of statutes of limitations. The Company accrues interest related to uncertain tax positions in interest expense or interest income and recognizes penalties related to uncertain tax positions in other income or other expense. As of December 31, 2023 and 2022, $0.5 million and $0.6 million, respectively, is accrued for the payment of interest and penalties related to income tax liabilities. The aggregate amount of interest and penalties expense (benefit) recorded in the statements of operations for the years ended December 31, 2023, 2022, and 2021, was $(0.1) million, $(0.5) million, and $(0.1) million, respectively.

12. Leases

The Company has operating leases primarily for corporate offices and data centers. Excluding office leases, leases with an initial term of 12-months or less that do not include an option to purchase the underlying asset are not recorded on the consolidated balance sheet and are expensed on a straight-line basis over the lease term.

The Company’s leases typically include certain renewal options to extend the leases for up to 25 years, some of which include options to terminate the leases within one year. The exercise of lease renewal options is at the Company’s sole discretion. The Company combines lease and non-lease components of its leases and currently has no leases with options to purchase the leased property. Payments of maintenance and property tax costs paid by the Company are accounted for as variable lease cost, which are expensed as incurred.

The components of lease cost are as follows (in thousands):


	Years Ended December 31,
	2023		2022		2021
Operating lease cost	$	13,074	$	12,506	$	12,369
Variable lease cost	2,663		2,771		3,140

Total lease cost	$	15,737	$	15,277	$	15,509

Supplemental cash flow information related to leases is as follows (in thousands):


	Years Ended December 31,
	2023		2022		2021
Cash paid for amounts included in the measurement of lease liabilities:
Operating cash flows from operating leases	$	14,039	$	14,020	$	19,623
Right-of-use assets obtained in exchange for new lease obligations:
Operating leases	$	6,359	$	7,693	$	20,944

Supplemental balance sheet information related to leases is as follows (in thousands, except lease term and discount rate):


	December 31,
	2023		2022
Assets:
Operating lease right-of-use assets	$	34,338	$	40,031
Liabilities:

Operating lease liabilities	29,074		33,910
Total operating lease liabilities	$	38,422	$	45,128


Weighted average remaining operating lease term (years)	5.31		5.53
Weighted average operating lease discount rate	3.47	%	3.21	%

The Company uses its incremental borrowing rate as the discount rate. As the Company enters into operating leases in multiple jurisdictions and denominated in currencies other than the U.S. dollar, judgment is used to determine the Company’s incremental borrowing rate including (1) conversion of its subordinated borrowing rate (using published yield curves) to an unsubordinated and collateralized rate, (2) adjusting the rate to align with the term of each lease, and (3) adjusting the rate to incorporate the effects of the currency in which the lease is denominated.

Maturities on lease liabilities as of December 31, 2023, are as follows (in thousands):


Fiscal Year Ending December 31,
2024	$	10,465
2025	8,162
2026	6,290
2027	5,580
2028	4,801
Thereafter	6,363
Total lease payments	41,661
Less: imputed interest	3,239
Total lease liability	$	38,422

13. Commitments and Contingencies

In accordance with ASC 460, Guarantees, the Company recognizes the fair value for guarantee and indemnification arrangements it issues or modifies if these arrangements are within the scope of the interpretation. In addition, the Company must continue to monitor the conditions that are subject to the guarantees and indemnifications, as required under the previously existing generally accepted accounting principles, to identify if a loss has occurred. If the Company determines it is probable a loss has occurred, then any estimable loss would be recognized under those guarantees and indemnifications. Under its customer agreements, the Company may agree to indemnify, defend, and hold harmless its customers from and against certain losses, damages, and costs arising from claims alleging that the use of its software infringes the intellectual property of a third-party. Historically, the Company has not been required to pay material amounts in connection with claims asserted under these provisions, and accordingly, the Company has not recorded a liability relating to such provisions.

Under its customer agreements, the Company also may represent and warrant to customers that its software will operate substantially in conformance with its documentation, and that the services the Company performs will be performed in a workmanlike manner by personnel reasonably qualified by experience and expertise to perform their assigned tasks. Historically, only minimal costs have been incurred relating to the satisfaction of warranty claims. In addition, from time to time, the Company may guarantee the performance of a contract on behalf of one or more of its subsidiaries, or a subsidiary may guarantee the performance of a contract on behalf of another subsidiary.

Other guarantees include promises to indemnify, defend, and hold harmless the Company’s executive officers, directors, and certain other key officers. The Company’s certificate of incorporation provides that it will indemnify and advance expenses to its directors and officers to the maximum extent permitted by Delaware law. The indemnification covers any expenses and liabilities reasonably incurred by a person, by reason of the fact that such person is, was, or has agreed to be a director or officer, in connection with the investigation, defense, and settlement of any threatened, pending, or completed action, suit, proceeding, or claim. The Company’s certificate of incorporation authorizes the use of indemnification agreements, and the Company enters into such agreements with its directors and certain officers from time to time. These indemnification agreements typically provide for a broader scope of the Company’s obligation to indemnify the directors and officers than set forth in the certificate of incorporation. The Company’s contractual indemnification obligations under these agreements are in addition to the respective directors’ and officers’ rights under the certificate of incorporation or under Delaware law.

Pending and Threatened Legal Proceedings

In April 2021, ACH files associated with one of the Company's mortgage servicing customers were inadvertently transmitted into the ACH network during a test of the Company's payment processing system. The Company took immediate corrective action and issued reversing ACH files, restoring affected accounts.

The Company was named as a defendant in seven class action lawsuits filed in various federal courts purportedly on behalf of consumers whose mortgage accounts were affected by the inadvertent ACH file transmission. The Company settled these lawsuits by establishing a $5.0 million fund out of which payments were to be made to class members and for attorneys’ fees and administrative costs. The $5.0 million was funded from insurance.

The inadvertent ACH file transmission also gave rise to investigations by the U.S. Consumer Financial Protection Bureau (the "CFPB") and state attorneys general in all 50 states, the District of Columbia, and certain U.S. territories as well as money transmission regulators in most of those jurisdictions. The Company settled the CFPB investigation for $25.0 million plus various undertakings. Payment was made to the CFPB from funds received from the insurance carriers during the year ended December 31, 2023. The Company also settled with the state money transmission regulators and attorneys general for a total of $20.0 million plus various undertakings. Funds for the state and money transmission regulator settlements, which were previously received from the insurance carriers and deposited into an escrow account, were paid during the year ended December 31, 2023. The Company believes that the CPFB and state undertakings will not adversely affect it.

The Company’s customer commenced an action for damages as a result of this event. The customer action remains pending and the Company presently intends to vigorously defend it. The Company expects that insurance will fund payments and costs associated with the defense of the customer action, and other claims that may be asserted against it, subject to the policy limits and other terms of the applicable policies.

Funds received from or expected to be received from insurance carriers are generally subject to the respective carriers' reservation of rights.

The Company is from time to time subject to other claims, litigation and investigations. While the Company believes that none of the currently pending matters is reasonably likely to have a material adverse effect on it, there can be no assurance with respect thereto or future matters.

14. Employee Benefit Plans

The Company offers various defined contribution plans for our U.S. and non-U.S. employees. Total defined contribution plan expense was $12.8 million, $13.4 million, and $13.0 million during the years ended December 31, 2023, 2022, and 2021, respectively.

ACI 401(k) Plan

The ACI 401(k) Plan is a defined contribution plan covering all domestic employees of the Company. Participants may contribute up to 75% of their annual eligible compensation up to a maximum of $22,500 (for employees who are under the age of 50 on December 31, 2023) or a maximum of $30,000 (for employees aged 50 or older on December 31, 2023). After one year of service, the Company matches 100% of the first 4% of eligible participant contributions and 50% of the next 4% of eligible participant contributions, not to exceed $5,000 per employee annually. Company contributions charged to expense were $5.0 million, $6.2 million, and $6.0 million during the years ended December 31, 2023, 2022, and 2021, respectively.

ACI Worldwide EMEA Group Personal Pension Scheme

The ACI Worldwide EMEA Group Personal Pension Scheme is a defined contribution plan covering substantially all ACI Worldwide (EMEA) Limited (“ACI-EMEA”) employees. For those ACI-EMEA employees who elect to participate in the plan, the Company contributes a minimum of 8.5% of eligible compensation to the plan for employees employed at December 1, 2000 or from 7% to 10% of eligible compensation for employees employed subsequent to December 1, 2000. ACI-EMEA contributions charged to expense were $1.7 million, $1.6 million, and $1.6 million, during the years ended December 31, 2023, 2022, and 2021, respectively.
