Aug 24 (Reuters) - J.M. Smucker reported a lower-than-expected profit for the first quarter due to higher marketing costs and lower sales of its popular Folgers coffee, and the company also trimmed its full-year earnings forecast.
The company's shares were down 4.7 percent at $113.29 in premarket trading on Thursday.
Sales in Smucker's U.S. coffee business fell 8 percent in the first quarter, while operating profits tumbled 29 percent, as retailers placed fewer orders due to the rising cost of coffee.
While pet foods sales, Smucker's biggest business, inched up 0.5 percent, profits declined by a fifth due to higher marketing spend for the launch of the Nature's Recipe brand at mass retailers.
Smucker, the maker of Jiffy peanut butter, has been facing intense competition in the pet foods department as bigger and deeper-pocketed rivals, such as Mars and Nestle, build their pet food portfolio.
Smucker also lowered its full-year profit forecast to $7.75-$7.85 per share from $$7.85-$8.05.
Net income fell 25 percent to $126.8 million, or $1.12 per share, in the three months ended July 31. Excluding items, the company earned $1.51 per share.
Net sales fell to $1.75 billion from $1.82 billion.
Analysts on average had expected the company to report a profit of $1.62 per share on revenue of $1.81 billion according to Thomson Reuters I/B/E/S. (Reporting by Uday Sampath Kumar; Editing by Savio D'Souza)
