LAFAYETTE, CALIFORNIA, December 10, 2002 – Central Garden & Pet Company (NASDAQ: CENT) today announced that it would restate its financial results for 1998 through 2002 in order to make adjustments for manufacturing-related costs associated with its Pennington and Kaytee subsidiaries. The changes will improve fiscal 2001 net results by $2.1 million; reduce net results by $1.7 million, $0.3 million and $0.1 million in fiscal years 2000, 1999 and 1998, respectively; and increase Cost of Goods Sold and decrease Selling General and Administrative expenses by like amounts in fiscal years 1998 through 2002. The adjustments will have no impact on cumulative results or 2002 profitability.

The restated financial statements are included in an amendment on Form 10-K/A for fiscal 2001 and amendments on Form 10-Q/A for the first three quarters of 2002 which were filed with the SEC today.

For the fourth quarter ended September 28, 2002, Central expects to report a profit of $0.04 per diluted share as compared to a loss of $0.74 per diluted share in the comparable 2001 period.

The amendments on Form 10-Q/A filed today also give effect to the results of the previously announced adoption by the Company of SFAS No. 142, “Goodwill and Other Intangible Assets” as of September 30, 2001. The Company will record a non-cash impairment charge of $147 million ($112 million after-tax) for fiscal 2002. This is expected to result in a loss of $3.44 per diluted share for fiscal 2002.

Net income for fiscal year 2002 before the accounting charge is expected to be $1.44 per diluted share, compared to a loss of $0.39 per diluted share in fiscal year 2001.

Said William Brown, chairman and chief executive officer of Central Garden & Pet, “We have made tremendous progress in the last few years transforming from a company engaged primarily in distribution to one that is now a strong, profitable competitor in higher-margin branded pet and garden products. The restatement is an unfortunate event, but it is modest and historical in nature. It does not impact 2002 profitability, nor does it alter in any way the fundamentally positive trends in our business today. We are pleased with our progress and profitability in 2002 and our prospects for 2003 and beyond.”

Central anticipates substantial earnings growth in fiscal 2003. The Company’s expectation for fiscal 2003 is that fully diluted EPS will be in the range of $1.70-$1.80.

The Company will discuss this earnings guidance and its fourth quarter and fiscal 2002 results on an analyst conference call on Thursday, December 12, 2002, at 5:30 p.m. EST. The analyst conference call will be simultaneously broadcast over the Internet through Central’s website, http://www.centralgardenandpet.com.
