(NEW YORK — May 3, 2012) —ACI Worldwide, Inc. (NASDAQ:ACIW), a leading international provider of payment systems, today announced financial results for the period ended March 31, 2012. We will hold a conference call on May 3, 2012, at 8:30 a.m. EST to discuss this information. Interested persons may also access a real-time audio broadcast of the teleconference atwww.aciworldwide.com/investors.

“ACI had a solid first quarter. Revenue from backlog grew 34% over prior-year as we concluded service implementations and added higher recurring maintenance and hosting revenues to our predictable business model,” said Chief Executive Officer Philip Heasley. “We also closed the S1 acquisition in mid-February and effected cost savings by the end of the first quarter which will amount to $33 million on an annualized basis. We remain excited about cross-selling opportunities that lie ahead of us now that the former S1 employees have joined the ACI family.”

FINANCIAL SUMMARY

Sales

Sales bookings in the quarter totaled $108.5 million. In the prior-year quarter sales bookings were $122.9 million. S1 contributed $24.4 million to sales in the quarter.

Backlog

60-month backlog increased $700 million to $2.317 billion as compared to $1.617 billion at December 31, 2011. 12-month backlog increased $158 million to $582 million as compared to $424 million at December 31, 2011. Contribution of the former S1 Corporation backlog accounted for $705 million of the rise in 60-month backlog and $174 million of the 12-month backlog during the quarter.

Revenue

Non-GAAP revenue increased $37.4 million, or 36%, over prior-year first quarter. Non-GAAP revenue excludes the impact of $4.3 million of deferred revenue that would have been recognized in the normal course of business by S1 but was not recognized due to GAAP purchase accounting requirements. GAAP revenue increased $33.1 million, or 32%, over prior-year first quarter. The acquisition of S1 Corporation contributed $22.5 million of revenue in the quarter for the period February 13-March 31, 2012.

Operating Expenses

Excluding $15.0 million of S1 acquisition related one-time expenses, operating expenses increased $27.2 million compared to the prior-year quarter primarily from the addition of S1. Total GAAP operating expenses for the quarter were $139.2 million.

Operating Income

Non-GAAP operating income increased $10.2 million, or 135%, compared to the prior-year quarter. GAAP operating income decreased $9.1 million compared to the prior-year quarter. Non-GAAP operating income excludes the deferred revenue adjustment due to purchase accounting as well as $15.0 million of S1 acquisition-related one-time expenses.

Adjusted EBITDA

Adjusted EBITDA increased to $31.1 million, growth of $14.4 million, or 86%, compared to the prior year quarter. Adjusted EBITDA excludes $15.0 million of acquisition related one-time expenses and the impact of $4.3 of million deferred revenue that would have been recognized in the normal course of business by S1 but was not recognized due to GAAP purchase accounting requirements.

Liquidity

We had $201.1 million in cash on hand as of March 31, 2012. The Company also paid $3.1 million in principal payments for the term credit facility during the first quarter 2012. Year to date to May 2, 2012, we repurchased 185,800 shares for $7.1 million. The maximum remaining dollar value of shares authorized for purchase under the stock repurchase program was approximately $68.0 million.

During Q1 2012, we received proceeds of $295 million from our credit facility to partially fund the purchase of S1 Corporation.

Operating Free Cash Flow

Operating free cash flow (“OFCF”) for the quarter was $4.0 million, a decrease of $8.3 million as compared to the March 2011 quarter.

Other Expense

Other expense for the quarter was $0.8 million, essentially flat as compared to other expense of $0.7 million in the March 2011 quarter.

Taxes

Income tax benefit in the quarter was $0.6 million, or a 23% effective tax rate, compared to income tax expense of $5.2 million, or a 76% rate, in the prior-year quarter. The income tax benefit for the quarter ended March 31, 2012 was favorably impacted by income in our foreign jurisdictions taxed as a lower rate and a loss in the US being taxed at a higher rate.

Net Income (loss) and Diluted Earnings Per Share

Net loss for the quarter ended March 31, 2012 was $1.8 million, compared to net income of $1.6 million during the same period last year, a reduction of $3.4 million.

Earnings (loss) per share for the quarter ended March 31, 2012 was $(0.05) per diluted share compared to $0.05 per diluted share during the same period last year. Excluding the impact of $15.0 million of S1 acquisition related one-time expenses and the impact of $4.3 of million deferred revenue that would have been recognized in the normal course of business by S1 but was not recognized due to GAAP purchase accounting requirements, earnings per share was $0.28 per diluted share.

Weighted Average Shares Outstanding

Total diluted weighted average shares outstanding were 36.7 million for the quarter ended March 31, 2012 as compared to 34.0 million shares outstanding for the quarter ended March 31, 2011. The number of weighted average shares outstanding was increased by 2.7 million due to the issuance of shares related to the acquisition of S1 Corporation. 7.1 million options to purchase shares, restricted share awards, common stock warrants and contingently issuable shares were excluded from the diluted earnings per share computation as their effect would have been anti-dilutive.

2012 Guidance

We are reiterating our annual guidance based upon what we are seeing in our business markets to date. Hence, guidance for calendar year is as follows: Revenue to achieve a range of $696-706 million, Operating Income of $99-104 million and Adjusted EBITDA of $165-170 million. Guidance for the year excludes the impact of professional fees and transaction-related expenses associated with the acquisition of S1 Corporation.

(1) This presentation includes non-GAAP measures. Our non-GAAP measures are not meant to be considered in isolation or as a substitute for commparable GAAP measures, and should be read only in conjunction with our consolidated financial statements prepared in accordance with GAAP.

(2) Adjustment for $4.3 million of deferred revenue that would have been recognized in the normal course of business by S1 but was not recognized due to GAAP pruchase accounting requirements.

(3) One-time expense related to the acquistion of S1, including, $7.4 million for employee related actions, $4.1 million for S1 acquisition fees and $ 1.1 million for other professional fees.

(4) Adjustments tax effected at 35%.

(5) Accelerated stock compensation expense for terminated employees related to the S1 acquisition.

(6) Diluted shares in the non-GAAP adjustment column includes dilutive effect of stock options, restricted share awards, and common stock warrants as if the Company had net income for the reported period.

To supplement our financial results presented on a GAAP basis, we use the non-GAAP measure indicated in the tables, which exclude certain business combination accounting entries and expenses related to the acquisition of S1, as well as other significant non-cash expenses such as depreciation, amortization and share-based compensation, that we believe are helpful in understanding our past financial performance and our future results. The presentation of these non-GAAP financial measures should be considered in addition to our GAAP results and are 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.

• Non-GAAP revenue, revenue plus deferred revenue that would have been recognized in the normal course of business by S1 if not for GAAP purchase accounting requirements. Non-GAAP revenue should be considered in addition to, rather than as a substitute for, revenue.

• Non-GAAP operating income, operating income (loss) plus deferred revenue that would have been recognized in the normal course of business by S1 if not for GAAP purchase accounting requirements and one-time expense related to the acquisition of S1. Non-GAAP operating income should be considered in addition to, rather than as a substitute for, operating income.

• Adjusted EBITDA, which is defined as net income (loss) plus income tax expense, net interest income (expense), net other income (expense), depreciation, amortization and non-cash compensation, as well as deferred revenue that would have been recognized in the normal course of business by S1 if not for GAAP purchase accounting requirements and one-time expense related to the acquisition of S1. Adjusted EBITDA should be considered in addition to, rather than as a substitute for, operating income.

• ACI is also presenting operating free cash flow, which is defined as net cash provided (used) by operating activities, less net after-tax payments associated with cash settlement of S1 stock options and S1 related transaction costs, net after-tax payments associated with IBM IT outsourcing transition, 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 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.

Reconciliation of Operating Free Cash Flow	Quarter Ended March 31,
(millions)	2012			2011

• 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.
