Costco Wholesale Corporation Reports Second Quarter and Year-to-Date Operating Results for Fiscal 2007, Including Certain One-Time Items, and February Sales Results

ISSAQUAH, WA -- (MARKET WIRE) -- March 8, 2007 --Costco Wholesale Corporation (NASDAQ: COST) announced today its operating results for the second quarter (12 weeks) and first half (24 weeks) of fiscal 2007, both ended February 18, 2007, and its February sales results.

Net sales for the second quarter of fiscal 2007 increased to $14.80 billion from $13.79 billion during the second quarter of fiscal 2006. In connection with recent changes to our consumer electronics returns policy, we undertook a more detailed analysis of our returns than we had performed historically. Although the operational data is still preliminary and being refined, the information indicated a longer timeframe over which returns are received and a lower realization rate on returned items than were previously estimated. Accordingly, as part of our quarterly analysis of our estimated reserve for sales returns, we increased by $224.4 million the sales reserve balance and took a charge to income for the quarter amounting to approximately $48.1 million ($30.4 million after tax). Excluding the sales reserve increase, net sales for the second quarter were $15.03 billion, representing a 9% increase over the prior year.

Net income for the second quarter of fiscal 2007 was $249.5 million, or $.54 per diluted share, compared to $296.2 million, or $.62 per diluted share, during the second quarter of fiscal 2006. Included in this year's second quarter results are three non-recurring items: (i) the $48.1 million pre-tax charge reflecting the reduced gross margin on the revised sales return reserve (discussed above); (ii) a pre-tax charge of $46.4 million associated with reducing adverse income tax consequences arising from the review of stock options by a special committee of the Board of Directors (this is $23.6 million less than the estimated expected charge announced last quarter); and (iii) a $10.1 million pre-tax benefit primarily to merchandise costs for an excise tax refund on prior merchandise sales of phone cards. Excluding these one-time items, second quarter net income would have been $302.9 million, or $.66 per diluted share.

Net sales for the first half of fiscal 2007 increased 8% to $28.66 billion from $26.46 billion during the first half of fiscal 2006. Excluding the sales return reserve adjustment recorded in the second quarter, net sales for the first half of fiscal 2007 would have been $28.88 billion, or a 9% increase over the prior year.

Net income for the first half of fiscal 2007 was $486.4 million, or $1.05 per diluted share, compared to net income for the first half of fiscal 2006 of $512.0 million, or $1.06 per diluted share. Excluding the three non-recurring items, as previously outlined, net income for the first half of fiscal 2007 would have been $539.5 million or $1.16 per diluted share, a 9% increase in earnings per diluted share over the prior year.

Comparable sales for the fiscal second quarter (12 weeks) and fiscal first half (24 weeks) of fiscal 2007, both ended February 18, 2007, were as follows:

                                   12 Weeks   24 Weeks

The Company today also reported net sales of $4.60 billion for the four weeks ended March 4, 2007, an increase of 9% from $4.22 billion in the same four-week period of the prior fiscal year. For the six-month retail reporting period of September through February, the twenty-seven weeks ended March 4, 2007, which includes the first two weeks of the Company's fiscal third quarter, the Company reported net sales of $32.40 billion, an increase of 9% from $29.65 billion during the comparable period of the prior fiscal year. These sales results exclude the adjustment to our sales returns reserve described above.

Comparable sales for the 4-week retail-reporting month of February and the 27-week retail-reporting period of September through February are as follows:

                                    4 Weeks   27 Weeks
