ACI WORLDWIDE, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

1. Condensed Consolidated Financial Statements

The unaudited condensed consolidated financial statements include the accounts of ACI Worldwide, Inc. and its wholly-owned subsidiaries (collectively, the “Company”). All intercompany balances and transactions have been eliminated. The condensed consolidated financial statements as of September 30, 2025, and for the three and nine months ended September 30, 2025 and 2024, are unaudited and reflect all adjustments of a normal recurring nature, which are, in the opinion of management, necessary for a fair presentation, in all material respects, of the financial position and operating results for the interim periods. The condensed consolidated balance sheet as of December 31, 2024, is derived from the audited financial statements.

The condensed consolidated financial statements contained herein should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2024, filed on February 27, 2025. Results for the three and nine months ended September 30, 2025, are not necessarily indicative of results that may be attained in the future.

The preparation of condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make judgments, estimates, and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed 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.

Other Current Liabilities

The components of other current liabilities are included in the following table (in thousands):


	September 30, 2025		December 31, 2024
Income taxes payable	$	16,737	$	3,284
Vendor financed licenses	15,522		14,462
Operating lease liabilities	8,563		9,265
Accrued interest	632		8,810
Other	41,087		37,987
Total other current liabilities	$	82,541	$	73,808

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 September 30, 2025, and December 31, 2024, was $ 201.7 million and $ 267.0 million, respectively.

Fair Value

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 measured 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 $ 399.2 million as of December 31, 2024. On June 18, 2025, the Company redeemed in full the Company's outstanding 2026 Notes. See Note 3, Debt, for additional information.

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

In accordance with the Accounting Standards Codification ("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, and as discussed in Note 9, Segment Information, in 2025 it realigned Banks and Merchants under a single general manager leading Payment Software. This change also resulted in a change in reporting units - combining Banks and Merchants into Payment Software, while maintaining Biller. As of September 30, 2025, the Company's goodwill balance of $ 1.2 billion was allocated $ 809.0 million to Payment Software and $ 417.0 million to Biller.

Recoverability of goodwill is measured using a discounted cash flow model incorporating discount rates commensurate with the risks involved. Use of a discounted cash flow model is common practice in impairment testing in the absence of available transactional market evidence to determine the fair value. The calculated fair value was substantially in excess of the current carrying value for all reporting units based upon the October 1, 2024, annual impairment test and there have been no indications of impairment in the subsequent periods.

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, and recorded its share of earnings and losses in the investment on a one-quarter lag basis. The Company had recorded an investment of $ 18.6 million, included in other noncurrent assets in the condensed consolidated balance sheet as of December 31, 2024. In March 2025, the Company sold its 30 % interest for $ 46.0 million. The Company recognized a gain on the sale of $ 25.9 million, which is recorded in other, net in the condensed consolidated statements of operations.

Recently Issued Accounting Standards Not Yet Effective

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The amendments in this update will require entities to provide disaggregated disclosures of specific expense categories underlying certain income statement expense line items on an annual and interim basis. ASU 2024-03 is effective for annual periods beginning after December 15, 2026, 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 that the adoption of ASU 2024-03 will have on its financial statement footnote disclosures.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments—Credit Losses (Topic 326) , to simplify the estimation of expected credit losses for certain short-term receivables and contract assets arising from revenue transactions. The ASU introduces a practical expedient that allows entities to assume current economic conditions will persist through the reasonable and supportable forecast period for eligible assets. ASU 2025-05 is effective for annual periods beginning after December 15, 2025, with early adoption permitted. The Company does not expect the adoption of ASU 2025-05 to have a material impact on its condensed consolidated financial statements or related disclosures.

In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software . The amendments in this update modernize the accounting guidance for internal-use software by replacing the previous stage-based model with a principles-based framework. Under the new guidance, cost capitalization begins when (1) management has authorized and committed to funding the software project and (2) it is probable that the project will be completed and the software will be used for its intended purpose. The update also supersedes the existing rules for website development costs, incorporating them into the internal-use software framework. ASU 2025-06 is effective for annual periods beginning after December 15, 2027, and early adoption is permitted. The Company is currently evaluating the impact that the adoption of ASU 2025-06 will have on its condensed consolidated financial statements and related disclosures.

Recently Adopted Accounting Pronouncements

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.

ASU 2023-09 is effective for our annual period beginning after December 15, 2024. ASU 2023-09 is expected to impact our income tax disclosures beginning with the consolidated financial statements included in the annual report on Form 10-K for the fiscal year ended December 31, 2025, but is not expected to have an impact on the Company's financial position, results of operations or cash flows.

7. 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):


	Three Months Ended September 30,		Nine Months Ended September 30,
	2025	2024	2025	2024
Weighted average shares outstanding:
Basic weighted average shares outstanding	103,245	104,770	104,316	105,651
Add: Dilutive effect of stock options, RSUs, and contingently issuable shares	650	1,248	948	901
Diluted weighted average shares outstanding	103,895	106,018	105,264	106,552

The diluted earnings per share computation excludes 1.7 million and 1.0 million options to purchase shares, RSUs, and contingently issuable shares during the three months ended September 30, 2025 and 2024, respectively, as their effect would be anti-dilutive. The diluted earnings per share computation excludes 1.7 million and 1.2 million options to purchase shares, RSUs, and contingently issuable shares during the nine months ended September 30, 2025 and 2024, respectively, as their effect would be anti-dilutive.

Common stock outstanding as of September 30, 2025, and December 31, 2024, was 103,256,397 and 105,254,913 , respectively.

8. Other, Net

The loss on extinguishment of debt represents the loss on redemption of the 2026 Notes as discussed in Note 3, Debt.

9. Segment Information

In 2025, the Company made a change in organizational structure to align with its strategic direction. As a result of this change, the Company reassessed its segment reporting structure due to changes in leadership structure and how the Company's chief operating decision maker ("CODM") assesses the Company's performance and allocates resources. Beginning in the first quarter of 2025, the Company reported financial performance based on its new operating segments, Payment Software, which includes bank and merchant customers, and Biller. The Company continues to use Segment Adjusted EBITDA as a measure of segment profitability.

The Company’s Chief Executive Officer is also the chief operating decision maker. 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.

Payment Software. Payment Software drives payments orchestration for banks and merchants. ACI provides payment solutions to large and mid-size banks globally for retail banking, 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. ACI’s support of merchants globally includes Tier 1 and Tier 2 merchants (in-store and online), payment service providers, independent selling organizations, value-added resellers, and acquirers who service them. These customers operate in a variety of verticals, including general retail, grocery, hospitality, dining, travel and ticketing, fuel, telecommunications, and others. The Company's solutions provide merchants with a secure, omnichannel payments platform that gives them flexibility and independence. The Company also offers secure solutions to online-only merchants that provide consumers with a convenient and seamless way to shop.

Biller. Within the Biller segment, ACI provides electronic bill presentment and payment services to companies operating in the consumer finance, insurance, healthcare, higher education, utility, government, mortgage, subscription provider, and telecommunications 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. ACI also provides fraud abuse protection to its Biller customers leveraging its proven AI, human, and data capabilities.

Revenue is attributed to the reportable segments based upon customer and product. 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, including budget and forecast-to-actual variances, and, therefore, Segment Adjusted EBITDA is presented in conformity with ASC 280, Segment Reporting. Segment Adjusted EBITDA is defined as earnings 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.

No other country outside the United States accounted for more than 10% of the Company's consolidated revenues during the three and nine months ended September 30, 2025, and nine months ended September 30, 2024.

10. Income Taxes

For the three and nine months ended September 30, 2025, the Company's effective tax rate was 23 % and 22 %, respectively. The Company reported a tax charge on pretax income for both the three and nine months ended September 30, 2025, with foreign entities recognizing earnings of $ 131.9 million and $ 231.1 million, respectively.

For the three and nine months ended September 30, 2024, the Company's effective tax rate was 24 % and 25 %, respectively. The Company reported a tax charge on pretax income for both the three and nine months ended September 30, 2024, with foreign entities recognizing earnings of $ 107.6 million and $ 148.1 million, respectively.

The Company’s effective tax rate could fluctuate on a quarterly basis due to the occurrence of significant and unusual or infrequent items, such as vesting of stock-based compensation or foreign currency gains and losses. The Company’s effective tax rate could also fluctuate due to changes in the valuation of its deferred tax assets or liabilities, or by changes in tax laws, regulations, accounting principles, or interpretations thereof. In addition, the Company is occasionally subject to examination of its income tax returns by tax authorities in the jurisdictions in which it operates. The Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of its provision for income taxes.

Table of contents

As of both September 30, 2025, and December 31, 2024, the amount of unrecognized tax benefits for uncertain tax positions was $ 21.0 million, excluding no related liabilities for interest and penalties as of September 30, 2025 and $ 0.4 million as of December 31, 2024.

The Company believes it is reasonably possible that the total amount of unrecognized tax benefits will decrease within the next 12 months by approximately $ 0.8 million, due to the settlement of various audits and the expiration of statutes of limitation.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted into U.S. tax law. OBBBA includes a broad range of tax reform provisions, such as the permanent extension of certain expiring provisions of the 2017 Tax Cuts and Jobs Act and modifications to the international tax framework. OBBBA has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The provisions that are effective in 2025 have not had a significant impact on the Company’s effective tax rate through September 30, 2025. OBBBA also allows certain elections that the Company can make for the current year, which the Company continues to evaluate.

Overview

ACI Worldwide, an innovator in global payments technology, delivers software solutions that power intelligent payments orchestration in real time so banks, merchants, and billers can drive growth, while continuously modernizing their payment infrastructures, simply and securely. With nearly 50 years of trusted payments expertise, we combine our global footprint with a local presence to offer enhanced payment experiences to stay ahead of constantly changing payment challenges and opportunities.

Our products are sold and supported directly and through distribution networks covering three geographic regions – the Americas; Europe, Middle East, and Africa (“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 of all sizes, central 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 ATMs, merchant point-of-sale (“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.

Table of contents

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, rapid growth of eCommerce, and the adoption of real-time payments enabling more people, governments, and businesses to embrace digital payments. 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 prevalent in account-to-account payments, which is delivering greater value to banks and their customers and has now been rolled out across the world and continues to see adoption with local schemes, such as FedWire. We are seeing global players with existing schemes working to expand capacity in anticipation of volume growth and new payment types. Domestic schemes such as Unified Payments Interface ("UPI") in India and others are being made available to their citizens for cross-border transactions when abroad. Mature markets, including India, the United Kingdom, Australia, Brazil, Malaysia, Singapore, and Thailand, continue to accelerate innovation, especially in terms of overlay services, driving new transactions. The United States is driving real-time payments adoption through TCH Real-Time Payments and the FedNow Service. Asia is one of the most innovative markets for adoption of real-time payment systems. According to ACI’s Prime Time for Real-Time report, Asia Pacific is the largest regional market, with four of the global top five real-time payment markets by volume. ACI provides solutions for commercial and central banks across Asia. Latin American countries are pushing ahead with real-time payments modernization initiatives, looking to replicate Brazil’s success with PIX. ACI is also providing solutions centrally in Colombia and Peru. 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 Red Hat, 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 private and public cloud, and we are supporting our customers' cloud strategies. Cloud technology innovations allow the financial services ecosystem to remove technical risk from their operations, accelerate innovation and time to market for new revenue-generating solutions for their customers, and 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. Cloud-native solutions running in a multi-tenant SaaS environment also allow ACI to expand our market coverage to smaller institutions, offering scalable solutions which are easy to integrate with but at price points that fit their budgets.

Payments intelligence, fraud, and compliance. The accelerated adoption of real-time payments, fraudsters leveraging artificial intelligence, and the ramping up of mandates increase the urgency for industry-wide collaboration to mitigate fraud with precision and achieve operational excellence. As the threat of sophisticated fraud becomes a greater concern for remitting and receiving institutions, consumers are challenged with increased friction to prevent illegitimate access of genuine accounts or funds to protect the consumer trust and confidence, while achieving their strategic objectives. Regulators are beginning to litigate between consumers and financial institutions on the losses, and between remitting and receiving banks on the accountability. 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 evolve our advanced machine learning and network intelligence capabilities to stop criminals and enable frictionless, legitimate business. Meanwhile, with payments intelligence, organizations can integrate intelligent services to enhance consumer relationships while achieving precise, real-time fraud and risk mitigation capabilities.

Omni-commerce. Shoppers are increasingly browsing, buying, and returning items across channels, including in-store, online, and mobile. This trend has led 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.

Open banking . Open banking is gaining momentum globally, and while it has been accelerated in Europe by regulations like PSD3, the United States is also seeing significant shifts driven by market demand and technology innovation rather than regulatory mandates. In the United States, the growing adoption of Request to Pay (RTP) offers an alternative to traditional bill payment methods, allowing payers to respond directly to payment requests with flexibility on timing, method, and amount. This aligns with the broader movement toward real-time payments, supported by platforms like the FedNow ® Service and The Clearing House’s RTP network. While the United States doesn't have a regulatory equivalent to PSD3, there's a strong push for open banking solutions that provide greater control and transparency for consumers, and RTP is a key trend within that space. By embracing both RTP and open banking trends in the United States, payment processors and financial institutions can offer more dynamic, flexible payment options, driving innovation and improving customer experience, while staying competitive in a rapidly evolving payments landscape. ACI is in a unique position to deliver service that takes advantage of our real-time payments software, our relationships with banks, merchants, and billers, and global 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.

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, Revenue From Contracts with Customers ) 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.

Table of contents

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 September 30, 2025, June 30, 2025, March 31, 2025, and December 31, 2024 (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.

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 condensed consolidated statements of operations. All fees from SaaS and PaaS arrangements that do 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. License revenue also includes license and capacity fees payable annually, quarterly, or monthly due to negotiated customer payment terms. 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 increased $4.5 million, or 3%, during the three months ended September 30, 2025, as compared to the same period in 2024.

• The impact of foreign currencies strengthening against the U.S. dollar resulted in a $2.1 million increase in license revenue during the three months ended September 30, 2025, as compared to the same period in 2024.

• Adjusted for the impact of foreign currency, license revenue for the three months ended September 30, 2025, increased $2.4 million, or 2%, as compared to the same period in 2024.

General and administrative expense increased $14.4 million, or 17%, during the nine months ended September 30, 2025, as compared to the same period in 2024.

• General and administrative expenses for the nine months ended September 30, 2025, included $6.3 million for cost reduction strategies and $0.5 million of other significant transaction-related expenses, compared to $4.3 million for cost reduction strategies and $1.0 million of other significant transaction-related expenses during the same period in 2024.

• Adjusted for the impact of cost reduction strategies and significant transaction-related expenses, general and administrative expense for the nine months ended September 30, 2025, increased $12.9 million, or 16%, as compared to the same period in 2024.

• The increase was primarily due to higher personnel and related expenses of $11.3 million, including a $8.4 million increase in stock-based compensation expense, as well as an increase in professional fees of $1.6 million.

Depreciation and Amortization

Depreciation and amortization decreased $14.5 million, or 17%, during the nine months ended September 30, 2025, as compared to the same period in 2024.

• Depreciation and amortization for the nine months ended September 30, 2024, included $4.4 million of accelerated depreciation related to the closure of a facility.

• Adjusted for the impact of the facility closure, depreciation and amortization expenses for the nine months ended September 30, 2025, decreased $10.1 million, or 12%, as compared to the same period in 2024.

• The decrease was primarily due to a decrease in amortization for fully amortized intangibles acquired through acquisitions.

Other Income and Expense

Interest expense for the nine months ended September 30, 2025, decreased $11.8 million, or 21%, as compared to the same period in 2024, primarily due to lower comparative debt balances during 2025 as well as a decrease in interest rates.

Interest income for the nine months ended September 30, 2025, was flat compared to the same period in 2024.

Other, net is primarily comprised of foreign currency transaction gains and losses. During the nine months ended September 30, 2025, other, net also included the $25.9 million gain on the sale of the Company's equity method investment and the $1.1 million loss on extinguishment of debt. Other, net was $18.9 million of income and $1.7 million of expense for the nine months ended September 30, 2025 and 2024, respectively.

Payment Software Segment Adjusted EBITDA increased $1.0 million for the three months ended September 30, 2025, compared to the same period in 2024, due to a $11.9 million increase in revenue primarily related to an increase in license revenues, partially offset by a $10.9 million increase in cash operating expense.

Biller Segment Adjusted EBITDA increased $1.2 million for the three months ended September 30, 2025, compared to the same period in 2024, due to a $18.7 million increase in revenue, partially offset by a $17.5 million increase in cash operating expense primarily for payment card interchange and other processing fees.

Payment Software Segment Adjusted EBITDA increased $44.0 million for the nine months ended September 30, 2025, compared to the same period in 2024, due to a $69.1 million increase in revenue primarily related to an increase in license and capacity revenue, partially offset by a $25.1 million increase in cash operating expense.

Biller Segment Adjusted EBITDA increased $3.7 million for the nine months ended September 30, 2025, compared to the same period in 2024, due to a $67.8 million increase in revenue, partially offset by a $64.1 million increase in cash operating expense primarily for payment card interchange and other 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, our cash and cash equivalents, and available borrowings under our revolving credit facility over the next 12 months and beyond.

Cash and cash equivalents consist of highly liquid investments with original maturities of three months or less. As of September 30, 2025, we had $199.3 million of cash and cash equivalents, of which $94.4 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 September 30, 2025, only the earnings from our Indian foreign subsidiaries are indefinitely reinvested. We are also permanently reinvested in the outside book/tax basis differences related to foreign subsidiaries. These outside basis differences could reverse through the sale of foreign subsidiaries, as well as various other events, none of which are considered probable as of September 30, 2025.

Available Liquidity

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


	September 30, 2025		December 31, 2024
Cash and cash equivalents	$	199,268	$	216,394
Availability under revolving credit facility	358,100		528,100
Total liquidity	$	557,368	$	744,494

The decrease in total liquidity is primarily due to increased borrowings on the revolving credit facility used to redeem the Company's outstanding 2026 Notes.

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 September 30, 2025, the full $75.0 million was available.

Stock Repurchase Program

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 June 2024, the board approved the repurchase of the Company's common stock of up to $400.0 million in place of the remaining purchase amounts previously authorized.

We repurchased 3,073,321 shares for $151.0 million under the program during the nine months ended September 30, 2025. Under the program to date, we have repurchased 65,941,158 shares for approximately $1.2 billion. As of September 30, 2025, the maximum remaining amount authorized for purchase under the stock repurchase program was approximately $207.1 million. See Note 6, Common Stock and Treasury Stock, to our unaudited condensed consolidated financial statements in Part I of this Form 10-Q for additional information.

On October 31, 2025, the Board of Directors approved $500.0 million for the stock repurchase program in place of the remaining purchase amounts previously authorized.

Cash Flows

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


	Nine Months Ended September 30,
	2025		2024
Net cash provided by (used by):
Operating activities	$	201,056	$	232,266
Investing activities	19,648		(31,641)
Financing activities	(235,247)		(170,445)

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 include employee expenditures, taxes, interest payments, and leased facilities.

Cash flows provided by operating activities were $31.2 million lower for the nine months ended September 30, 2025, compared to the same period in 2024. Operating cash flows for the current year decreased primarily due to lower customer receipt collections as a result of lower invoiced amounts at the prior year-end and higher income taxes paid, partially offset by improved profitability.

Table of contents

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; 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 first nine months of 2025, we received net proceeds of $46.0 million from the sale of our equity method investment. In addition, we used cash of $26.4 million to purchase software, property, and equipment, as compared to $31.6 million during the same period in 2024.

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 the first nine months of 2025, we repaid $400.0 million for the redemption of the 2026 Notes and $12.0 million of other debt payments. In addition, we used $150.0 million to repurchase common stock and $23.9 million for the repurchase of stock-based compensation awards for tax withholdings. We received net proceeds of $170.0 million on the Revolving Credit Facility and $170.6 million on the Incremental Term Loan, used for the redemption of the 2026 Notes. In addition, we received proceeds of $3.8 million from the exercise of stock options and the issuance of common stock under our 2017 Employee Stock Purchase Plan, as amended, and $6.3 million for settlement assets and liabilities due to processing timing. During the first nine months of 2024, we repaid a net $47.8 million on the Term Loan under the Amendment, $9.3 million of other debt payments, and $5.1 million of debt issuance costs. In addition, we used $127.7 million to repurchase common stock and $9.3 million for the repurchase of stock-based compensation awards for tax withholdings. We received net proceeds of $7.0 million on the Revolving Credit Facility, proceeds of $4.1 million from the exercise of stock options and the issuance of common stock under our 2017 Employee Stock Purchase Plan, as amended, and $17.7 million for settlement assets and liabilities due to processing timing.

Contractual Obligations and Commercial Commitments

For the nine months ended September 30, 2025, there have been no material changes to the contractual obligations and commercial commitments disclosed in Item 7 of our Form 10-K for the fiscal year ended December 31, 2024, other than as disclosed in Note 3, Debt .

Critical Accounting Estimates

The preparation of the condensed consolidated financial statements requires us to 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 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 condensed consolidated financial statements. Actual results could differ from those estimates.

The accounting policies that reflect our more significant estimates, judgments, and assumptions, and that we believe are the most critical to aid in fully understanding and evaluating our reported financial results, include the following:

• Revenue Recognition

• Intangible Assets and Goodwill

• Stock-Based Compensation

• Accounting for Income Taxes

During the nine months ended September 30, 2025, there were no significant changes to our critical accounting policies and estimates. Please refer to Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in Part II, Item 7 of our Annual Report on Form 10-K for our fiscal year ended December 31, 2024, for a more complete discussion of our critical accounting policies and estimates.

ITEM 3. 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 nine months ended September 30, 2025. 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 September 30, 2025, a hypothetical ten percent increase or decrease in effective interest rates would increase or decrease interest income by $0.3 million annually.

As of September 30, 2025, we had $873.1 million outstanding under our Credit Facility. Our Credit Facility has a floating rate, which was 6.01% as of September 30, 2025. A hypothetical ten percent increase or decrease in effective interest rates would increase or decrease interest expense related to the Credit Facility by approximately $5.2 million.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Management, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer, performed an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded our disclosure controls and procedures are effective as of September 30, 2025.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) under the Exchange Act) during the quarter ended September 30, 2025, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

From time to time, we are involved in various litigation matters arising in the ordinary course of our business. We are not currently a party to any legal proceedings the adverse outcome of which, individually or in the aggregate, we believe would be likely to have a material effect on our financial condition or results of operations.

ITEM 1A. RISK FACTORS

There have been no material changes to the risk factors disclosed in Item 1A of our Form 10-K for the fiscal year ended December 31, 2024. Additional risks and uncertainties, including risks and uncertainties not presently known to us, or that we currently deem immaterial, could also have an adverse effect on our business, financial condition and/or results of operations.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Issuer Purchases of Equity Securities

The following table provides information regarding our repurchases of common stock during the three months ended September 30, 2025:


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
July 1, 2025 through July 31, 2025	244,278	(1)	$	45.08	244,183
August 1, 2025 through August 31, 2025	108,828	(1)	43.13		81,834
September 1, 2025 through September 30, 2025	82,348	(1)	50.69		33,505
Total	435,454					$	207,145,000

(1) Pursuant to our 2020 Equity and Performance Incentive Plan, we granted RSUs. Under each arrangement, shares are issued without direct cost to the employee. During the three months ended September 30, 2025, 229,527 shares of RSUs vested. We withheld 75,932 of those shares to pay the employees’ portion of the applicable minimum payroll withholding.

In 2005, the board approved a stock repurchase program authorizing us, as market and business conditions warrant, to acquire our common stock. The board periodically authorizes additional funds for the program, with the intention of using existing cash and cash equivalents to fund these repurchases. In June 2024, the board approved the repurchase of the Company's common stock of up to $400.0 million in place of the remaining purchase amounts previously authorized. As of September 30, 2025, the maximum remaining amount authorized for purchase under the stock repurchase program was approximately $207.1 million.

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, the 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.
