CENTRAL GARDEN & PET REPORTS SECOND QUARTER RESULTS

REAFFIRMS FISCAL 2003 EARNINGS GUIDANCE

OF $1.70-$1.80 PER DILUTED SHARE

LAFAYETTE, CALIFORNIA, May 1, 2003 – Central Garden & Pet Company (NASDAQ: CENT) today announced its financial results for the fiscal second quarter of 2003, ended March 29, 2003.

Net sales for the second quarter were $330.5 million compared with $290.7 million in the comparable fiscal 2002 period. The Company recorded net income for the quarter of $13.5 million, or $0.68 per diluted share, compared with a net income of $10.9 million, or $0.53 per diluted share, in the comparable year-ago period.

The improved results for the second fiscal quarter of 2003 were driven by continued growth of higher margin proprietary branded product sales as well as lower litigation expenses. Partially offsetting these improvements were higher than normal grain prices, higher insurance costs and higher interest expense, due primarily to the Company’s issuance of $150 million of 9 ¹/8% senior subordinated notes due 2013 and retirement of its 6% convertible subordinated notes. In connection with this refinancing, the Company incurred a one-time charge to interest expense in the 2003 second quarter of $1.4 million.

Income from operations for the second fiscal quarter of 2003 improved to $28.2 million from $21.3 million in the year-ago period. Depreciation and amortization expense for the most recent quarter totaled $4.3 million, the same as the prior year. Unusual expenses, consisting primarily of litigation expenses, were $1.3 million and $8.8 million in the second fiscal quarters of 2003 and 2002, respectively.

Net sales for the first half of fiscal 2003 were $542.4 million, compared with $501.4 million in the comparable 2002 period. Net income for the first half of 2003 was $12.8 million, or $0.64 per diluted share, compared with $9.4 million, or $0.51 per diluted share, in the comparable year ago period, before the effect of adopting SFAS No. 142 on September 30, 2001. In the first half of fiscal 2002, including the effect of the non-cash SFAS No. 142 accounting charge of $146.7 million, or $112.2 million after-tax, the Company reported a net loss of $102.8 million, or $4.44 per diluted share.

Central continues to anticipate substantial earnings growth and reaffirms its expectation that fiscal 2003 net income will be in the range of $1.70-$1.80 per diluted share.

The Company will discuss its fiscal second quarter 2003 results on an earnings conference call today at 5:30 p.m. EDT. The earnings conference call will be simultaneously broadcast over the Internet through Central’s website, http://www.centralgardenandpet.com/.
