Item 8.01 Other Events.

As expected, The Nasdaq Stock Market (“Nasdaq”) announced on May 27, 2010, that it is removing Frontier Financial Corporation’s (“Corporation”) securities from listing and registration on Nasdaq. Nasdaq will file a Form 25 with the Securities and Exchange Commission to complete the delisting. The delisting becomes effective ten days after the Form 25 is filed. The Corporation’s stock was suspended on May 12, 2010, and has not traded on Nasdaq since that time. We understand the Corporation’s common stock has been quoted on the Pink Sheets, a centralized electronic quotation service for over-the-counter securities, under the symbol “FTBK.PK”. The Corporation can give no assurance, however, that trading in its stock will continue on the Pink Sheets or on any other securities exchange or quotation medium or the willingness of any market makers to trade the Corporation’s common stock in the future.

As of May 27, 2010, the Corporation believes its only material assets, excluding its investment in Frontier Bank, which investment is expected to be written off completely, consist only of a limited amount of cash, and that after the payment of the Corporation’s liabilities and expenses of winding up its business and pending matters, the Corporation anticipates that little, if any, assets or funds will be left for distribution or winding up of the Corporation by its board of directors, pursuant to the Washington Business Corporation Act, or filing a voluntary petition seeking relief under Chapter 7 of Title 11 of the United States Code.

Shareholders should contact their tax preparer about claiming a loss or worthless stock deduction for their investment on their 2010 tax return to be filed in 2011.

You can find out about your stock holdings in Frontier by contacting the transfer agent, American Stock Transfer – Shareholder Services, at 1-866-659-2641 or 1-800-937-5449, or you may access your account information on its website at www.amstock.com using your account number and social security number.
