Exhibit 99.3

UNAUDITED PRO FORMA COMBINED CONDENSED

CONSOLIDATED FINANCIAL STATEMENTS

The following unaudited pro forma combined condensed consolidated financial information and explanatory notes illustrate the effect of the merger of Center Financial Corporation (“Center”) with and into Nara Bancorp, Inc. (“Nara”) on Nara’s financial position and results of operations based upon the companies’ respective historical financial positions and results of operations under the acquisition method of accounting with Nara treated as the acquirer. The unaudited pro forma combined condensed consolidated financial information has been derived from and should be read in conjunction with the historical consolidated financial statements and the related notes of (i) Nara included in its Annual Report on Form 10-K for the year ended December 31, 2010 and its quarterly report on Form 10-Q for the quarter ended June 30, 2011, and (ii) Center included in Exhibits 99.1 and 99.2 to the Current Report on Form 8-K of Nara to which this Exhibit 99.3 is attached.

In accordance with generally accepted accounting principles in the United States of America, or GAAP, the assets and liabilities of Center will be recorded by Nara at their estimated fair values as of the date the merger is completed. The unaudited pro forma combined condensed consolidated balance sheet as of June 30, 2011 assumes the merger took place on that date. The unaudited pro forma combined condensed consolidated income statements for the six months ended June 30, 2011 and for the year ended December 31, 2010 assume the merger took place on January 1, 2010.

The pro forma financial information includes Nara’s estimated adjustments to record assets and liabilities of Center at their respective fair values. These adjustments are subject to change depending on changes in interest rates and the components of assets and liabilities as of the merger date and as additional information becomes available and additional analyses are performed. The final amount and allocation of the purchase price will be determined after the merger is completed and after completion of further analyses to determine the fair value of Center’s tangible and identifiable intangible assets and liabilities as of the date the merger is completed. Increases or decreases in the estimated fair values of the net assets acquired as compared with the information shown in the unaudited pro forma combined condensed consolidated financial information may change the amount of the purchase price allocated to goodwill and other assets and liabilities and may impact Nara’s statements of income due to adjustments in yield and/or amortization of the adjusted assets or liabilities. Any changes to Center’s stockholders’ equity, including results of operations from June 30, 2011 through the date the merger is completed, will also change the purchase price allocation, which may include the recording of a lower or higher amount of goodwill. The final adjustments may be materially different from the unaudited pro forma adjustments presented herein.

Nara anticipates that the merger with Center will provide the combined company with financial benefits that include reduced combined operating expenses. The pro forma information, which is intended to illustrate the financial characteristics of the merger and the combined company under one set of assumptions, does not reflect the benefits of expected cost savings or opportunities to earn additional revenues, or all integration costs that may be incurred and, accordingly, should not be considered a prediction of future results. It also does not necessarily reflect what the historical results of the combined company would have been had our companies been combined during the period shown.

The unaudited pro forma stockholders’ equity and net income should not be considered indicative of the market value of Nara common stock or the actual or future results of operations of Nara for any period. Actual results may be materially different than the pro forma information presented.

Notes to Unaudited Pro Forma Combined Condensed Consolidated Financial Statements

(In thousands, except share and per share data unless otherwise stated)

The unaudited pro forma combined condensed consolidated financial information related to the merger includes the unaudited pro forma combined condensed consolidated balance sheet as of June 30, 2011 assuming the merger was completed on June 30, 2011. The unaudited pro forma combined condensed consolidated income statements for the six months ended June 30, 2011 and for the year ended December 31, 2010 were prepared assuming the merger was completed on January 1, 2010. For the purposes of the pro forma combined condensed consolidated financial statements, the purchase price is currently estimated at approximately $206.2 million, which is based upon a price of $6.62 per share (the closing price on September 12, 2011) of Nara common stock and an implied value per share of Center common stock of $5.17. The pro forma adjustments included herein reflect the conversion of Center common stock into Nara common stock at the exchange ratio stated in the merger agreement of 0.7804 of a share of Nara common stock for each of the approximately 39.9 million shares of Center Financial common stock outstanding as of June 30, 2011.

The merger will be accounted for as an acquisition of Center by Nara in accordance with the acquisition method of accounting as detailed in ASC 805-10 (previously SFAS No. 141(R)), Business Combinations. The acquisition method of accounting requires an acquirer to recognize the assets acquired, the liabilities assumed and any noncontrolling interest in the acquiree based on their fair values as of the date of acquisition. As described in more detail in ASC 805-10, goodwill, if any, will be recognized as of the acquisition date, in the amount equal to the excess of the consideration transferred over the fair value of identifiable net assets acquired. Based on Nara’s preliminary purchase price allocation, goodwill of approximately $8.2 million is currently expected to be recorded by Nara in the period the merger is completed.

As the merger is recorded using the acquisition method of accounting, all loans of Center are recorded at fair value, including adjustments for credit, and no allowance for credit losses is carried over to Nara’s balance sheet. In addition, certain anticipated nonrecurring costs associated with the merger, such as severance costs, accounting fees, legal and other professional fees and conversion related expenditures are not reflected in the pro forma statements of income.

While the recording of the acquired loans at their fair value will impact the prospective determination of the provision for loan losses and the allowance for loan losses, for purposes of the unaudited pro forma combined condensed consolidated income statements for the six months ended June 30, 2011 and for the year ended December 31, 2010, we assumed no adjustments to the historical amount of Center’s provision for credit losses. If such adjustments were estimated, there could be a reduction, which could be significant, to the historical amounts of Center’s provision for credit losses presented.

For purposes of the unaudited pro forma combined condensed consolidated income statements for the six months ended June 30, 2011 and for the year ended December 31, 2010, we assumed no adjustments to the historical deferred tax asset valuation in the amount of $3.0 million and $6.0 million, respectively, recorded by Center. Had Nara acquired Center as of January 1, 2010, the reversal of all or a portion of the deferred tax asset valuation allowance of the combined entity could have differed materially from the amount presented in the unaudited pro forma combined condensed consolidated income statements. In addition, the pro forma combined condensed consolidated financial statements do not take into account the impact, if any, of an ownership change under Section 382 of the Code that would have occurred with respect to Center (and potentially Nara) as of January 1, 2010.

The historical financial results of Nara include merger and acquisition integration costs of $0.9 million and $1.0 million for the six months ended June 30, 2011 and the year ended December 31, 2010, respectively. These integration costs primarily consisted of legal and other professional fees and due diligence related costs. The historical financial results of Nara also include $2.2 million and $4.3 million of preferred stock dividends and discount accretion for the six months ended June 30, 2011 and the year ended December 31, 2010. These amounts relate to Nara’s participation in the U.S. Department of the Treasury’s Capital Purchase Program.

The historical financial results of Center for the six months ended June 30, 2011 and the year ended December 31, 2010 included $11.0 million and $22.0 million provisions for credit losses and professional fees of $0.6 million and $0.7 million associated with the merger, respectively. The historical financial results of Center also include $1.5 million and $3.0 million of preferred stock dividends and discount accretion for the six months ended June 30, 2011 and the year ended December 31, 2010, respectively, as well as an intrinsic value of $29 million for the beneficial conversion feature of its Series B Preferred Stock issued in December 2009.

The merger is expected to result in annual cost savings to be achieved following the consummation of the merger. These expected savings have not been included in the pro forma combined amounts.

The unaudited pro forma combined condensed consolidated financial information for the merger includes the unaudited pro forma combined condensed consolidated balance sheet as of June 30, 2011 assuming the merger was completed on June 30, 2011. The unaudited pro forma combined condensed consolidated income statements for the six months ended June 30, 2011 and the year ended December 31, 2010 was prepared assuming the merger was completed on January 1, 2010.

In accordance with GAAP, subsequent to the effective date Nara will record the fair value difference pertaining to market rate differential into interest income over the remaining term of loan portfolio, which is estimated to be five years. In addition, the fact that the loans acquired with deteriorated credit quality are recorded at fair value at acquisition date could result in a reduction in the amount of loan loss provision expense required on these loans in the future.

Center in connection with the merger. Some of these costs may not be tax deductible. The deductibility of such costs will be determined subsequent to the completion of the merger.

The plan to integrate the operations of Nara and Center following the merger is still being developed. The specific details of this plan will continue to be refined over the next several months, and will include assessments of the personnel, benefit plans, premises, equipment and service contracts to determine the extent of redundancies that may be eliminated. Certain decisions arising from these assessments may involve involuntary termination of employees, vacating leased premises, changing information systems, canceling contracts with service providers and selling or otherwise disposing of certain furniture and equipment. Also included in the restructuring costs are additional integration costs consisting of costs relating to corporate name changes and incremental communication costs to customers and business partners, among others. Costs associated with these actions will be recorded based on the nature of the cost and timing of the integration actions.
