CHURCH & DWIGHT REPORTS RECORD FIRST QUARTER EPS OF $1.11

PRINCETON, NJ, MAY 11, 2010 – Church & Dwight Co., Inc. (NYSE:CHD) today reported net income for the quarter ended April 2, 2010 of $80.0 million or $1.11 per share, compared to last year’s reported net income of $62.6 million or $0.88 per share.  Earnings per share increased 21%, excluding a plant restructuring charge of $0.04 per share in 2009. This year’s first quarter was six days longer than the comparable period in the prior year for its US businesses due to the Company’s fiscal calendar.

First Quarter Review

Reported net sales for the first quarter increased 9.2% to $634.6 million.  Organic sales increased 7.7% for the total Company and 8.1% for our total domestic and international consumer business, which excludes the impact of foreign exchange rate changes and divestitures.

James R. Craigie, Chairman and Chief Executive Officer, commented, “We are very pleased with our solid first quarter business results in what continues to be a difficult economic and competitive environment.  Consumer appeal for our high-quality premium and value-oriented products continues to be strong.  Both gross margin and operating margin expanded, reflecting the cost savings from our new laundry plant and the continuing benefit of our robust cost reduction programs.”

Consumer Domestic sales were $466.7 million, a $28.6 million increase or 6.5% above the prior year first quarter sales.First quarter organic sales increased by 8.1% as a result of higher sales of ARM & HAMMER liquid laundry detergent, ARM & HAMMER Super Scoop cat litter, NAIR, ORAJEL, TROJAN, AIM toothpaste and KABOOM bathroom cleaner, partially offset by lower sales of XTRA liquid laundry detergent.

Consumer International sales were $102.7 million, a $19.9 million increase or 24.0% above the prior year first quarter sales.  Excluding the16.2% favorable effect of foreign exchange rate changes, organic sales increased by 8.0%, primarily reflecting increased sales in Canada, Brazil, UK and Australia.

Specialty Products sales were $65.2 million, a $5.2 million increase or 8.6% above the prior year first quarter sales.  Excluding the 4% favorable effect of foreign exchange rate changes, organic sales for the first quarter increased by 4.6%, primarily due to growth in sodium bicarbonate sales.

Gross margin increased to 45.0% in the first quarter compared to 42.9% in the same quarter last year.  Excluding the $5.2 million plant restructuring charge in last year’s first quarter, gross margin expanded 120 basis points.  The increase in gross margin reflects the benefits of cost reduction programs, manufacturing at our new laundry facility and favorable product mix.  These benefits were partially offset by higher slotting costs and remaining costs associated with the closing of the North Brunswick plant.

Marketing expense was $68.9 million in the first quarter, a $2.6 million increase over the prior year first quarter.  The marketing spending was focused on the Company’s eight power brands.  Marketing expense as a percentage of net sales decreased 50 basis points to 10.9% in the quarter compared to 11.4% in last year’s first quarter.

Selling, general, and administrative expense (SG&A) was $84.6 million in the first quarter, a $6.3 million increase over the prior year first quarter.  SG&A as a percentage of net sales was 13.3% in the quarter, a decrease of 20 basis points from the prior year first quarter.  The increase in SG&A spending is attributed to foreign exchange rate changes, higher research and development expenses and higher costs associated with our global information systems upgrade.

Operating income increased 26.1% to $132.0 million in the first quarter compared to $104.7 million in the prior year first quarter.Operating margin expanded 280 basis points to 20.8%.  Excluding the plant restructuring charges in the prior year, operating margin expanded 190 basis points.

Equity in earnings of affiliates decreased $1.4 million due to lower income from a joint venture.

The effective tax rate in the first quarter was 36.2% compared to 37.1% in the prior year first quarter.

Net Debt and Free Cash Flow

At quarter end, the Company had net debt of $298 million (total debt of $745 million less cash of $447 million).  The Company repaid $71 million of bank debt in the quarter.

For the quarter, the Company reported $72.0 million of net cash from operations compared to $92.0 million in the prior year.  The decrease in net cash from operations is primarily related to higher inventories related to new product launches, higher receivables and higher cash tax payments.  For the first quarter, the Company generated $ 62.7 million in free cash flow compared to $70.7 million in the prior period.   Free cash flow is defined as net cash from operations less capital expenditures.

Capital expenditures in the first quarter were $9.2 million compared to $21.3 million in the prior year first quarter.   Last year’s first quarter included approximately $15 million of capital expenditures related to the new manufacturing facility in York County, Pennsylvania.

Acquisitions/Divestitures

In the first quarter, the Company completed the divestitures of two of its non-core brands, BRILLO and LAMBERT KAY pet products.

During the second quarter, the Company entered into a definitive asset purchase agreement to acquire the SIMPLY SALINE brand of products from Blairex Laboratories, Inc.  The proposed acquisition is subject to customary conditions to closing.  The transaction is expected to be completed during the second quarter of 2010.

The proposed acquisition meets the Company’s previously stated acquisition criteria: the brand holds the #1 position in the nasal saline solution category, has high growth potential, and is expected to be gross margin accretive to the Company.  Annual sales of Simply Saline are approximately $20 million.  In addition, the acquisition will complement the Company’s existing STERIMAR brand nasal saline solution business in Europe and other parts of the world.

The acquisitions and divestitures are expected to be neutral to earnings per share in 2010 and accretive to earnings per share in 2011.

Outlook for 2010

With regard to 2010, Mr. Craigie said, “We are launching our best new product line-up ever in 2010 and the customer response has been excellent with distribution gains across almost every key category.  We expect to deliver organic sales growth of approximately 4-5% in 2010 based on our strong pipeline of innovative new products supported by effective marketing programs.  We remain confident in our previously announced earnings per share estimate of $3.93 to $4.00 in 2010, which is an increase of 13% to15%, excluding plant restructuring charges of $0.24 per share and the favorable litigation settlement of $0.17 per share in 2009.”

“We expect second quarter earnings per share of $0.93-$0.95, up 8%-10% excluding the prior period plant restructuring charge of $0.05 per share.  First half earnings per share is expected to increase approximately 15% excluding plant restructuring charges in 2009 of $0.09 per share.”

The following discussion addresses the non-GAAP measures used in this press release and reconciliations of non-GAAP measures to the most directly comparable GAAP measures:

Adjusted Net Income per Share, Adjusted Gross Margin and Adjusted Operating Profit Margin

The press release provides information regarding the Company’s net income per share, gross margin and operating profit margin adjusted to exclude restructuring charges related to plant closing expenses. Management believes that the presentation of adjusted net income per share, gross margin and operating profit margin (including reconciliation information in the press release) is useful to investors because it enables them to assess the Company’s historical performance exclusive of extraordinary events that do not reflect the Company’s day-to-day operations.

Organic Sales Growth

The press release provides information regarding organic sales growth, namely net sales growth excluding the effect of acquisitions, divestitures and foreign exchange rate changes from year-over-year comparisons. Management believes that the presentation of organic sales growth is useful to investors because it enables them to assess, on a consistent basis, sales trends related to products that were marketed by the Company during the entirety of relevant periods, without the effect of foreign exchange rate changes that are out of the control of, and do not reflect the performance of, management.

Free Cash Flow

Free cash flow is net cash from operating activities less capital expenditures.  Free cash flow is used by the Company's management, and management believes it is useful to investors, to help assess funds available for investing activities, such as acquisitions and financing activities, including debt payments, dividend payments and share repurchases.  Free cash flow also is one of the measures used in determining management's annual incentive award.  Free cash flow does not represent cash available only for discretionary expenditures, since the Company has mandatory debt service requirements and other contractual and non-discretionary expenditures.  Free cash flow excluding the capital expenditures for the new Pennsylvania facility is used by management, and management believes it is useful to investors, to assess funds available for investing activities, such as acquisitions and financing activities, including debt payments, dividend payments and share repurchases exclusive of extraordinary events that do not reflect the Company's day-to-day operations.  Please refer to the condensed cash flow statement for details.
