99 Cents Only Stores to Announce Its Year-End 2004 and Fourth Quarter 2004 Earnings on June 30, 2005; Announces Restatement of Financial Statements Related to Lease Accounting and Depreciation.

CITY OF COMMERCE, Calif. -- 99 Cents Only Stores(R) (NYSE:NDN) will issue a press release announcing its year-end 2004 and unaudited fourth quarter 2004 earnings on Thursday, June 30, 2005, at 6:00 A.M. PDT. A conference call to discuss the earnings release is scheduled for Thursday, June 30, 2005, at 11:00 A.M. PDT.

As previously announced, following a review undertaken by the Company and discussions with its current and former independent registered public accountants, and in response to views expressed by the Chief Accountant of the Securities and Exchange Commission ("SEC") in a February 7, 2005, letter to the American Institute of Certified Public Accountants, the Company will be restating its financial statements for 2002, 2003, and the first three quarters of 2004 for its accounting for operating lease rent holidays, and its accounting for leasehold improvements funded by landlord incentives or allowances under operating leases (tenant improvement allowances). In addition, the Company has completed the previously reported analysis of useful lives used to depreciate certain building and leasehold improvements and determined, in consultation with its current and former independent registered public accountants, that a restatement of these prior period financial statements is required to reflect adjustments to these useful lives to periods longer than initially assigned, in order to properly reflect the economic lives of these assets. The amount of these adjustments to each prior period will be disclosed in the earnings release. These adjustments are non-cash and have no impact on the Company's cash flows, cash position or revenues. All prior periods once restated, as well as the fourth quarter of 2004, were profitable. The Company remains profitable and debt free with a strong cash position.
