Financial Review

Key Takeaways from the Quarter Strong sales growth Sales growth across all regions led to 36% increase in sales over prior-year quarter 60-month backlog growth of $27 million over March quarter, $74 million over YE 2010 Strong revenue quarter Led by strong growth in recurring revenue, up $16.1 million, or 25%, over prior-year quarter 91% of quarter's revenue, or $103.2 million, derived from backlog Expense growth drivers Higher selling and marketing expense Higher R&D expense to invest in accelerated product development 11

Key Takeaways from the Quarter (cont) Strong growth in operating income Up $6.0 million over prior-year quarter Strong growth in adjusted EBITDA Up $7.1 million over prior-year quarter Lower effective tax rate Favorable impact of $2.2 million release of tax reserves 12

Backlog as a Contributor of Quarterly Revenue Backlog from monthly recurring revenues and project go-lives continues to drive current quarter GAAP revenue, leading to predictable quarterly performance Consistent revenue from current quarter sales 13

Raising 2011 Guidance First half year strength driving higher full year expectations Top-line revenue and expenses both trending higher due largely to FX impact Sales should fall in the mid- $500 million range 14 * Adjusted EBITDA = operating income + Depreciation and Amortization + non-cash compensation expense

Non-GAAP Financial Measures ACI is presenting operating free cash flow, which is defined as net cash provided (used) by operating activities, less net after-tax payments associated with employee related activities, net after-tax payments associated with IBM IT outsourcing transition, and capital expenditures and plus or minus net proceeds from IBM. Operating free cash flow is considered a non-GAAP financial measure as defined by SEC Regulation G. We utilize this non-GAAP financial measure, and believe it is useful to investors, as an indicator of cash flow available for debt repayment and other investing activities, such as capital investments and acquisitions. We utilize operating free cash flow as a further indicator of operating performance and for planning investing activities. Operating free cash flow should be considered in addition to, rather than as a substitute for, net cash provided (used) by operating activities. A limitation of operating free cash flow is that it does not represent the total increase or decrease in the cash balance for the period. This measure also does not exclude mandatory debt service obligations and, therefore, does not represent the residual cash flow available for discretionary expenditures. We believe that operating free cash flow is useful to investors to provide disclosures of our operating results on the same basis as that used by our management. 26

Non-GAAP Financial Measures ACI also includes backlog estimates which are all software license fees, maintenance fees and services specified in executed contracts, as well as revenues from assumed contract renewals to the extent that 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. Backlog is considered a non-GAAP financial measure as defined by SEC Regulation G. Our 60-month backlog estimate represents expected revenues from existing customers using the following key assumptions: 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. License and facilities management arrangements are assumed to renew at the end of their committed term at a rate consistent with our historical experiences. Non-recurring license arrangements are assumed to renew as recurring revenue streams. 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. 27

Non-GAAP Financial Measures Estimates of future financial results are inherently unreliable. Our backlog estimates require substantial judgment and are based on a number of assumptions as described above. These assumptions may turn out to be inaccurate or wrong, including for reasons outside of management's control. For example, our customers 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 in the customer's industry or geographic location, or we may 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 actually recognized in future periods. Accordingly, there can be no assurance that contracts included in backlog estimates will actually generate the specified revenues or that the actual revenues will be generated within the corresponding 60-month period. Backlog should be considered in addition to, rather than as a substitute for, reported revenue and deferred revenue. ACI also includes Adjusted EBITDA, which is defined as net income (loss) plus income tax expense, net interest income (expense), net other income (expense), depreciation and amortization and non-cash compensation. Adjusted EBITDA is considered a non-GAAP financial measure as defined by SEC Regulation G. Adjusted EBITDA should be considered in addition to, rather than as a substitute for, operating income (loss). 28

Non-GAAP Financial Measures The presentation of these non-GAAP financial measures should be considered in addition to our GAAP results and is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP. Management generally compensates for limitations in the use of non-GAAP financial measures by relying on comparable GAAP financial measures and providing investors with a reconciliation of non-GAAP financial measures only in addition to and in conjunction with results presented in accordance with GAAP. We believe that these non-GAAP financial measures reflect an additional way of viewing aspects of our operations that, when viewed with our GAAP results, provide a more complete understanding of factors and trends affecting our business. 29
