Exhibit 99.1

Center Financial to Report Record Second Quarter Results; Company Delays Conference Call and Issuance of Final Q2 Results Pending Adjustments to June 30, 2004 Financial Statements

LOS ANGELES, Aug 04, 2005 (BUSINESS WIRE) — Center Financial Corporation (Nasdaq:CLFC), the holding company of Center Bank, today said it is delaying the timing of its 2005 second quarter earnings news release and conference call, pending adjustments to the company’s previously reported June 30, 2004 financial statements to ensure compliance with hedge accounting principles generally accepted in the United States.

While the company believes that its interest rate swaps have been effective as hedges since their inception in 2001, management recently determined that the method of evaluating the effectiveness of the hedges used in 2002 through 2004 did not meet the technical requirements necessary to qualify for the hedge accounting treatment utilized during those periods. As a result, the company will be restating its results from 2002 through 2004 with respect to the reporting of gains and losses due to changes in the fair market values of its interest rate swaps. Notwithstanding that the restatement is expected to have a material effect on certain of the company’s results of operations during the 2002 through 2004 periods, it is not expected to affect the company’s financial condition for any of those periods.

Center Financial also said it expects to report the following results for the 2005 second quarter:

• Net income increased to $6.0 million, or $0.36 per diluted share

• Net loans rose to $1.1 billion

• Total deposits grew to $1.3 billion

• Total assets increased to $1.5 billion

• Return on average assets and return on average equity improved to 1.74% and 24.47%, respectively

• Efficiency ratio improved to 47.81%

• Revenues advanced to $26.8 million

• Net interest income before provision for loan losses increased to $15.6 million

• Noninterest income rose to $5.0 million
