EAST WEST BANCORP COMMENCES PUBLIC OFFERING OF

11 MILLION SHARES OF COMMON STOCK

Pasadena, California — July 20, 2009 — East West Bancorp, Inc. (Nasdaq: EWBC), parent company of East West Bank, today announced that it has commenced a public offering of 11 million shares of its common stock, par value $0.001. The offering also includes an option for the underwriter to purchase an additional 1,650,000 shares.

The public offering completes a comprehensive capital-raising plan that to-date has raised $168.9 million of tangible common equity through exchanges of Series A preferred shares into common shares, private sales of common stock, and the desecuritization of private label MBS securitizations.

“With our recent actions that have increased tangible common equity by $168.9 million and this offering, we believe we have the capital to weather an even more severe economic environment than we currently expect,” stated Dominic Ng, Chairman, President and Chief Executive Officer of East West. “And this additional capital will provide us with flexibility to pursue new growth opportunities or keep up an aggressive pace in resolving problem assets, should economic conditions get worse,” concluded Ng.

Barclays Capital Inc. is acting as the sole underwriter of the public offering. A preliminary prospectus supplement relating to the offering has been filed with the SEC. Copies of the preliminary prospectus supplement, and the accompanying prospectus for the offering, may be obtained from Barclays by telephone at (888) 603-5847, or by mail c/o Broadridge, Integrated Distribution Services, 1155 Long Island Avenue, Edgewood, NY 11717, or by email at barclaysprospectus@broadridge.com.
