Financials Review Scott Behrens, Principal Financial Officer

16 Key Takeaways from the Quarter . Revenue growth of 11% at $109.2 million in the current quarter versus $98.1 million in June 2007 quarter . $13.5 million attributable to Faster Payments (license fees + services) . Growth of $3.7 million in monthly recurring revenues versus prior year quarter . Decline in capacity fees largely due to impact of large deal in Canada booked in Q2-07 . Sales were up $36.1 million over Q1, $14.7 million over prior year quarter . OFCF of ($10.9) million versus $11.7 million in June 2007 quarter ~$12 million variance in personnel costs including consultants/contractors paid Higher capex of ~$5 million; primarily from build-out of new Omaha premise Prepayment of $2 million for new Omaha facility rent Higher cash severance of $1 million as compared to $30k in prior year quarter . 12-month backlog growth of $23 million year over year 12-month backlog was reduced by the revenue recognition of the Faster Payments transactions in the UK, MasterCard in the US

17 Takeaways from the Quarter (cont) . Overall rate of deferred revenue growth has slowed as we move backlog into current period GAAP • Short term deferred revenue shrunk to $121.1 million as we booked Faster Payments deals in the UK and Middle East switch revenue as well as Mastercard in US . Expenses up $14.7 million versus prior year quarter primarily due to: • $9.2 million in services-related personnel costs including • $6 million contractor and personnel expense • $1 million ACI On Demand -related • $5.8 million in selling & marketing due to timing of commission expense as well as increased headcount to support our 2008 sales plan, including IBM Alliance sales initiatives • $3.7 million in IBM transition costs and severance related to IBM outsourcing . Other income was positively impacted by non-cash gain of $2.9 million on the mark to market of the interest rate swap

18 Backlog is Still a Significant Contributor to current period Revenue • Continue to see backlog generating most of GAAP revenue in Q2 2008 due to: – Services release as large deals moved out of backlog – Implementation & professional services contributing 28% of Q2 2008 revenue versus an 18% contribution in Q2 2007 Qtr. Ended June 08 Qtr.

19 Revenue by Product Category 05-06-07-08 • Business shifting away from non-recurring license driven revenue • Monthly recurring revenue is growing in absolute terms as is implementation and professional services – Monthly recurring revenue- inclusive of quarterly recurring revenue- has risen significantly- up 22% in past three years- but it is a smaller percentage of overall revenue due to growth of services business revenue – Implementation/services have nearly doubled in past 3 years • Driven by the recognition of long-tenured backlog deals • General growth in the professional services, post-implementation business $ in thousands CY 2005 Actuals CY 2006 Actuals CY 2007 Actuals 1H 2008 Actuals Revenue by Type ($) Non-recurring License & Capacity 91,400 107,568 91,667 42,680 Monthly Recurring 179,458 190,700 219,223 114,635 Implementation & Professional Services 46,848 57,848 63,321 44,495 Total Revenue 317,706 356,116 374,211 201,810 Revenue by Type (%) Non-recurring License & Capacity 28.8% 30.2% 24.5% 21.1% Monthly Recurring 56.5% 53.5% 58.6% 56.8% Implementation & Professional Services 14.7% 16.2% 16.9% 22.1% Total Revenue 100.0% 100.0% 100.0% 100.0%

20 Guidance Update • Sales – 95-98% of original expectations – ~2-5% lower than earlier view or approximately $430-440 million due to extended sales cycles • OFCF lower due to sales mix; new accts/new apps require heavier use of cash in service implementation than term extensions • Rev-log reduced slightly from previous guidance due to lower sales expectations • Expenses to grow 8-10% over calendar 2007 expense – $8 million additional IBM IT Outsourcing transition costs announced in March 2008 • Taxes- No change; anticipate $14 million cash expenditure for the year Key Metrics Current Guidance Prior Guidance Prior Year Comments OFCF $45-50 $65 $53 Booking more new accounts/new apps which require use of implementation cash prior to milestones than in prior year Rev-Log $190-195 $200 $157 Impacted by reduction in sales from earlier guidance

30 Non-GAAP Financial Measures • This presentation includes operating free cash flow and backlog estimates. ACI is presenting these non-GAAP guidance measures to provide more transparency to its earnings, focusing on operating free cash flow and backlog • ACI is presenting operating free cash flow, which is defined as net cash provided (used) by operating activities, excluding cash payments associated with the cash settlement of stock options, cash payments associated with one-time employee related actions, less capital expenditures, plus or minus net proceeds from IBM. 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 is considered a non-GAAP financial measure as defined by SEC Regulation G. • 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. 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. These non-GAAP measures should be considered as a supplement to, and not as a substitute for, or superior to, income from operations and net income per share calculated in accordance with GAAP. 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. We also believe that this measure can assist investors in comparing our performance to that of other companies on a consistent basis without regard to certain items, which do not directly affect our ongoing cash flow.

31 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. • 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. • 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.
