8x8, Inc. Announces Change in
Treatment of Investor Warrants
Restatement of Previously Filed Financial Statements Will Be Made

SANTA CLARA, CA - June 15, 2007 -- 8x8, Inc. (the "Company") (Nasdaq: EGHT), announced today that a recent Securities and Exchange Commission (SEC) speech discussing the accounting treatment of warrants (an agreement with an investor which allows the purchase of a certain amount of a company's stock, at a certain price, for a certain amount of time), has led the Company to conclude that its historical accounting for three outstanding external investor warrants from the Company's fiscal years 2005 and 2006 must be restated to reflect the SEC's recent discussion. These warrants were issued in connection with financing transactions in 2004 and 2005.

The Company today filed with the SEC a current report on Form 8-K regarding this issue, and also filed a notice of late filing of its annual report on Form 10-K for the fiscal year ended March 31, 2007. The Company stated in these filings that it will restate its financial statements for fiscal years 2005 and 2006 as part of its 2007 Form 10-K filing, and will also file amended reports on Form 10-Q for each of the first three quarters of fiscal year 2007. The Company expects to file these restated reports within the 15-day extension period afforded by SEC Rule 12b-25 under the Securities Exchange Act of 1934.

"This technical accounting adjustment in our financial reports will result in non-cash charges and do not affect the underlying business of 8x8 in any way," said 8x8 Chairman and CEO Bryan R. Martin. "While the Company is still completing its analysis of the impact this change will have on its historical financials, the Company has determined that the modification of this warrant accounting will have no impact on previously reported revenue and income from operations or net cash flows for the fiscal years ended March 31, 2005, 2006 and 2007. The net effect of the restatement is to add a liability to our balance sheets, and to modify our reported net loss to reflect the change in market value of the affected warrants while they remain outstanding." Mr. Martin concluded, "For the three fiscal years ended March 31, 2005, 2006 and 2007, the restated results will reduce our previously reported net loss by approximately $4M, $1M, and $4M, respectively."
