Costco Wholesale Corporation announced net sales for the third quarter of fiscal 2003 increased 11% to $9.34 billion from $8.44 billion during the third quarter of fiscal 2002. On a comparable warehouse basis, that is warehouses open at least a year, net sales increased 6%.

Net income for the third quarter of fiscal 2003 increased 18% to $153.8 million, or $.33 per share (diluted), from $130.4 million, or $.28 per share (diluted), during the third quarter of fiscal 2002.

Net sales for the first thirty-six weeks of fiscal 2003 increased 9% to $28.28 billion from $25.94 billion during the first thirty-six weeks of fiscal 2002. Comparable warehouse sales during the first thirty-six weeks of fiscal 2003 increased 5% over the prior year’s level.

Net income for the first thirty-six weeks of fiscal 2003 increased 6% to $481.6 million, or $1.02 per diluted share, compared to net income for the first thirty-six weeks of fiscal 2002 of $452.6 million, or $.96 per diluted share. Excluding the pre-tax charge of $26 million ($16 million or $.03 per diluted share after tax) reflecting an increase in workers compensation loss reserves, which was booked in the second quarter of fiscal 2003, net income for the first thirty-six weeks of fiscal 2003 would have been $497.6 million, or $1.05 per diluted share, reflecting a 10% increase in net income over the prior year’s thirty-six week period.
