PETCO Animal Supplies, Inc. Updates Guidance for First Quarter and Fiscal 2003

        SAN DIEGO—(BUSINESS WIRE)—May 19, 2003—PETCO Animal Supplies, Inc. (Nasdaq:PETC) today updated its guidance for fiscal 2003 first quarter ended May 3, 2003, and full year ending January 31, 2004. The Company currently expects first quarter earnings per diluted share in the range of $0.19 - $0.20 and, accordingly, now expects full fiscal year 2003 earnings per diluted share in the range of $1.09 - $1.11, before the non-cash effect of an accounting change.

        As previously announced, the Company will be adopting a new accounting standard, Emerging Issues Task Force Issue No. 02-16 (EITF 02-16), on accounting for consideration received from suppliers. The adoption of the new accounting standard will result in the Company reporting higher gross margins and higher selling, general and administrative expenses. The Company today announced that adoption of EITF 02-16 is expected to reduce first quarter earnings per diluted share by $0.01 and full fiscal year 2003 earnings per diluted share by approximately $0.07. Accordingly, including the effect of the new accounting standard, the Company now expects earnings per diluted share for the first quarter of 2003 in the range of $0.18 - $0.19 and full fiscal year 2003 earnings per diluted share in the range of $1.02 - $1.04.

        The Company continues to expect to report a comparable store net sales increase in the range of 4.5% - 5.0% for the first quarter of fiscal 2003. This increase in comparable store net sales would come on top of the 9.3% increase achieved in the first quarter of fiscal 2002. For the full fiscal year 2003, the Company continues to expect a comparable store net sales increase of approximately 6%.
