PRINCETON, NJ, MAY 6, 2004 - Church &Dwight Co., Inc. (NYSE:CHD) today announced, ahead of its Annual Meeting of Stockholders, preliminary results for the first quarter of 2004. Diluted net income per share advanced to $0.70 per share from $0.50 a year ago. Revenues increased to $296 million, up 19% from the comparable period a year ago. This year's first quarter, which closed April 2, was six days longer than the comparable period a year ago, and also benefited from the acquisition of the Unilever North American oral care business late last year.

The Company also announced that it has reached a non-binding understanding with its partner, Kelso &Company, to purchase Kelso's 50% interest in Armkel, LLC, for a purchase price of approximately $254 million. It is expected that the purchase will be completed on or about May 30, 2004. The closing is subject to customary closing conditions, including completion of financing. Armkel's sales in 2003 totalled $411 million and net income was $50.2 million.

On completion of this transaction, the Company will incur certain non-cash accounting charges, primarily related to the revaluation of Armkel's inventories and the write-off of deferred financing costs, which will have an adverse effect on earnings in the second and third quarters. The Company expects the acquisition to be earnings accretive by early 2005.

Robert A. Davies, III, Chairman and Chief Executive Officer of Church &Dwight, said, "Armkel has been a highly successful addition to our business during the past two and one-half years, and we are very pleased to have been able to move up the timetable to acquire the remainder of the Company."

The Company will provide more details when it releases full first quarter results on Tuesday, May 11, and during the earnings conference call on that date at 10:00 a.m. (ET). The dial-in number is 800-299-7635, access code: Church & Dwight. A replay of the call will be available from 5/11/04 to 5/18/04. The replay dial-in number is 888-286-8010, access code: 28202909.
