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-sized 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 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, 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 types as well as provide a convenient consumer payments experience that helps billers optimize growth and operational efficiencies while improving customer experience. 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.

About Segments Disclosures

Segment disclosures break a company into its reportable operating units, revealing revenue, profit, and asset allocation that consolidated financial statements obscure. Under ASC 280, segments must match how the chief operating decision maker views the business, providing a window into internal management structure and resource allocation priorities.

Key signals: compare segment margins to identify which units drive profitability and which destroy value. Watch for changes in the number of reportable segments — segment aggregation or disaggregation often coincides with strategic shifts or attempts to obscure declining performance. Intersegment elimination patterns reveal internal pricing practices. The reconciliation between segment totals and consolidated figures exposes corporate overhead allocation and unallocated items. Geographic revenue concentration highlights regulatory and currency exposure. Compare segment-level capital expenditure against segment revenue to assess where management is investing for future growth versus harvesting existing assets.
