Tyson Foods says its fourth-quarter net income is less than half what it posted last year, with higher grain costs offsetting better prices and revenue.

The meat producer said Monday that it earned $97 million, or 26 cents per share, compared with $213 million, or 57 cents per share, a year ago. The results fell short of the 31 cents per share that analysts had expected. Revenue climbed 13 percent to $8.4 billion.

The company increased prices sharply, with chicken up 5 percent, pork up 13 percent, and beef up 19 percent. Still, profit margins remain under pressure because of higher costs at Tyson, based in Springdale, Ark. Tyson has two procsssing plants in the Hutchinson area.
