Oil-Dri Announces Second Quarter Results

CHICAGO – (March 9, 2012) – Oil-Dri Corporation of America (NYSE: ODC) today announced net sales of $60,203,000 for the second quarter ended January 31, 2012, a 5% increase compared with net sales of $57,201,000 in the same quarter one year ago. Net income for the second quarter was $3,239,000, or $0.45 per diluted share, an 80% increase compared with net income of $1,777,000 or $0.25 per diluted share, for the same quarter one year ago.

Net sales for the six-month period were $119,785,000, a 6% increase compared with net sales of $113,486,000 in the same period one year ago. Net income for the six-month period was $4,314,000, or $0.60 per diluted share, approximately equal to net income of $4,296,000, or $0.60 per diluted share, in the same period one year ago.

Second Quarter Business Review

President and Chief Executive Officer Daniel S. Jaffee said, “We are pleased with the second quarter results as we were able to deliver meaningful earnings growth primarily driven by higher sales and profitability in the Business to Business products group. We are encouraged that many of these products are an essential part of the feed and food supply chain that supports the growing population trend worldwide.

“Advertising and promotional costs were substantially lower for Cat’s Pride Fresh & Light in the quarter in order to coordinate our expenditures with the expanded distribution that we anticipate during the second half of the fiscal year.

“The continued focus on value added products combined with lower natural gas costs contributed to improved gross margins in the quarter from 21.8% to 24.2%.”

Second Quarter Segment Review

Net sales for the Company’s Business to Business products were up 18% from one year ago driven by an increase in units sold, a favorable product mix and a higher average net selling price. Net sales of products sold as carriers for corn rootworm insecticides, vegetable oil processing and animal health increased, while co-packaged cat litters were down. Group income was up 42% in the quarter due to product mix and an increase in units sold.

Net sales for the Company’s Retail and Wholesale products for the second quarter were down 1% from one year ago primarily due to decreased sales in foreign subsidiaries. Net sales for cat litter and industrial absorbents products were even year over year. Sales declined in private label cat litters but were offset by increases of Cat's Pride Fresh & Light and other branded scoopable litters. Group income was up 18% due to decreased spending in the quarter for advertising and promotional activities versus prior year and product mix.

Financial Review

On December 13, 2011, Oil-Dri’s Board of Directors declared quarterly cash dividends of $0.17 per share of outstanding Common Stock and $0.1275 per share of outstanding Class B Stock. The dividends were payable March 9, 2012 to stockholders of record at the close of business on February 24, 2012. The Company has paid cash dividends continuously since 1974 and has increased dividends annually for the past eight years.

At the end of the second quarter, the annualized dividend yield on the Company’s Common Stock was 3.2%, based on the quarter’s stock closing price of $20.99 per share and the latest cash quarterly dividend of $0.17.

Cash, cash equivalents and short-term investments at January 31, 2012, totaled $36,324,000. Capital expenditures for the six months totaled $3,512,000, which was $1,122,000 less than the quarter’s depreciation and amortization of $4,634,000. Cash generated from operating activities increased 42% to $10,281,000.

Looking Forward

Jaffee continued, “We are encouraged by the positive sales trends in the Business to Business products group. This segment has helped to support promotional costs of our Cat’s Pride Fresh & Light product launch.

“We anticipate increased advertising and promotional activities throughout the second half of Fiscal 2012.  While we expect to see expanded distribution and sales growth from Cat’s Pride Fresh & Light we do not believe the incremental sales and gross profit will offset the expense of launching this product line during this fiscal year.”
