NEW YORK (Standard&Poor's CreditWire) Jan. 18, 2001--Standard&Poor's today revised its outlook on PetsMart Inc. to negative from stable. At the same time, Standard&Poor's affirmed its double–'B'-minus corporate credit and senior secured bank loan ratings and its single–'B' subordinated debt rating on PetsMart. The outlook revision is based on Standard&Poor's belief that a slowing U.S. economy and higher inventory shrink and operating expenses in fiscal 2000 (ending January 2001) will result in EBITDA below fiscal 1999's level.
