Exhibit 99.2

UNAUDITED CONDENSED COMBINED PRO FORMA FINANCIAL INFORMATION

The following unaudited pro forma condensed combined statement of income for the year ended December 31, 2012 are presented on a pro forma basis to give effect to the tender offer (the “Offer”) and related transactions as if they had been completed on January 1, 2012. The following unaudited pro forma combined balance sheet as of December 31, 2012 is presented on a pro forma basis to give effect to the offer and related transactions as if they had been completed on December 31, 2012.

The following unaudited pro forma condensed combined financial statements, or the “pro forma financial statements,” were derived from and should be read in conjunction with:

The consolidated financial statements of ACI and ORCC as of December 31, 2012 and for the year ended December 31, 2012 have been adjusted in the pro forma financial statements to give effect to items as disclosed in Note 4. The pro forma financial statements should be read in conjunction with the accompanying notes to the pro forma financial statements.

The unaudited pro forma adjustments were based on publicly available information, including the ACI 10-K, and the ORCC 2012 consolidated financial statements provided in Exhibit 99.1 of this Form 8-K/A. The unaudited pro forma adjustments were also based on certain assumptions and estimates that ACI believes are reasonable based on such publicly available information. Additional information may exist that could materially affect the assumptions and estimates and related pro forma adjustments. Pro forma adjustments have been included only to the extent appropriate information is known, factually supportable and reasonably available to ACI.

The pro forma financial statements have been presented for informational purposes only. The pro forma financial statements are not necessarily indicative of what the combined company’s financial position or results of operations actually would have been had the offer been completed as of the dates indicated. In addition, the pro forma financial statements do not purport to project the future financial position or operating results of the combined company. There were no material transactions between ACI and ORCC during the periods presented in the pro forma financial statements that would need to be eliminated.

The pro forma financial statements have been prepared using the acquisition method of accounting under generally accepted accounting principles in the United States (“U.S. GAAP”). ACI has been treated as the acquirer in the offer for accounting purposes. Assumptions and estimates underlying the pro forma adjustments are described in the accompanying notes, which should be read in conjunction with the pro forma financial statements.

Acquisition accounting is dependent upon certain valuations and other studies that have not yet been completed. Accordingly, the pro forma adjustments are preliminary and have been made solely for the purpose of preparing the pro forma financial statements and are based upon preliminary information available at the time of the preparation of this Form 8-K/A. Differences between these preliminary estimates and the final acquisition accounting may occur and these differences could have a material impact on the pro forma financial statements and the combined company’s future results of operations and financial position.

The pro forma financial statements do not reflect any cost savings or other synergies that the combined company may achieve as a result of the offer or the costs to integrate the operations of ACI and ORCC or the costs necessary to achieve these cost savings and other synergies. The effects of the foregoing items could, individually or in the aggregate, materially impact the pro forma financial statements.

Notes to the Unaudited Pro Forma Condensed Combined Financial Statements

1. Description of Transaction

On March 11, 2013, the ACI Worldwide, Inc. (the “Company” or “ACI”) completed the exchange offer for Online Resources Corporation (“ORCC”) and all its subsidiaries. The Company paid cash of $3.85 per share of common stock for approximately $132.9 million and $127.2 million for the Series A-1 Convertible Preferred Stock for a total purchase price of $260.1 million (the “Merger”). As a leading provider of online banking and full service bill pay solutions, the acquisition of ORCC adds Electronic Bill Presentment and Payment (“EBPP”) solutions as a strategic part of ACI’s Universal Payments portfolio. It also strengthens the Company’s online banking capabilities with complementary technology, and expands the Company’s leadership in serving community banking and credit union customers.

Each outstanding option to acquire ORCC common stock was canceled and terminated at the effective time of the Merger and converted into the right to receive an equivalent number of options to purchase ACI common stock. Each ORCC restricted stock unit was vested immediately prior to the effective time of the Merger and received $3.85 per share.

The Company used $300.0 million of senior bank financing arranged through Wells Fargo Bank, National Association, as Administrative Agent, to fund the acquisition.

2. Basis of Presentation

These pro forma financial statements were prepared using the acquisition method of accounting in accordance with Financial Accounting Standards Board’s Accounting Standards Codification (ASC) 805, Business Combinations, and use the fair value concepts defined in ASC 820, Fair Value Measurements and Disclosures. Certain reclassifications have been made to the historical financial statements of ORCC to conform with ACI’s presentation as detailed in the following tables:

Further review of ORCC’s accounting policies could identify additional differences between the accounting policies of the two companies that, when conformed, could have a material impact on the financial statements of ACI as a combined company. At this time, ACI is not aware of any differences that would have a material impact on the financial statements of ACI as a combined company.

ASC 805 requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values as of the consummation of the combination. In addition, ASC 805 establishes that the consideration transferred be measured at the consummation of the combination at the then-current market price.

ASC 820 defines the term “fair value” and sets forth the valuation requirements for any asset or liability measured at fair value, expands related disclosure requirements and specifies a hierarchy of valuation techniques based on the nature of the inputs used to develop the fair value measures. Fair value is defined in ASC 820 as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” This is an exit price concept for the valuation of the asset or liability. In addition, market participants are assumed to be buyers and sellers in the principal (or the most advantageous) market for the asset or liability. Fair value measurements for an asset assume the highest and best use by these market participants. As a result of these standards, ACI may be required to record assets which are not intended to be used or sold and/or to value assets at fair value measures that do not reflect ACI’s intended use of those assets. Many of these fair value measurements can be highly subjective and it is also possible that other persons, applying reasonable judgment to the same facts and circumstances, could develop and support a range of alternative estimated amounts.

3. Consideration Transferred

The following is a summary of consideration transferred to consummate the offer:

The Company incurred approximately $4.7 million in transaction related expenses during the three months ended March 31, 2013, including fees to the investment bank, legal and other professional fees. The transaction related expenses have not been included in the pro forma adjustments.

4. Pro Forma Adjustments

Adjustments included in the column under the heading “Pro Forma Adjustments” represent the following:

The pro forma balance sheet adjustments reflect the effect of the acquisition assuming the acquisition occurred on December 31, 2012.

The amounts above are considered preliminary. The allocation of purchase price is based upon certain external valuations and other analyses that have not been completed as of the date of this filing, including, but not limited to, certain tax matters, property and equipment, intangible assets, and deferred revenue. Critical estimates in valuing certain intangible assets include but are not limited to future expected cash flows from customer relationships, and acquired developed technologies; brand awareness and market position, as well as assumptions about the period of time the brand will continue to be used in our product portfolio; and discount rates. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. Accordingly, the purchase price allocations are preliminary and are subject to future adjustments during the maximum one-year allocation period. Differences between these preliminary estimates and the final acquisition accounting may occur and these differences could have a material impact on the pro forma financial statements and the combined company’s future results of operations and financial position.

The Company believes that if there were to be any substantial changes in the purchase price allocation it would be to software or other identifiable intangibles assets. The Company is unable to quantify the effect of potential adjustments until the valuation is finalized. The table below illustrates the effect of a 10% increase or decrease in software and other identifiable intangible assets on the pro forma financial statements:

Amortization expense for the above intangible assets is estimated at $14.8 million annually. A 10% decrease or increase in the intangibles value would decrease or increase, respectively, that estimate by $1.5 million annually.

For purposes of calculating the pro forma interest expense, ACI used a rate of 2.46%, the interest rate as of March 31, 2013 on the incremental term loan, for the year ended December 31, 2012.
