The Jackson, Mississippi-based company reported net income of $11.1 million, or 47 cents per share, for the first quarter ended Aug 30. It earned $18.0 million, or 76 cents per share, in the year-ago period.

Net sales rose about 16 percent to $206.9 million driven by higher egg prices and demand for eggs in both the retail and food service markets.

Cal-Maine sells the majority of its shell eggs in 29 states across the southwestern, southeastern, mid-western and mid-Atlantic regions of the United States.

CEO Fred Adams Jr. said corn and soybean meal prices peaked in July, but have dropped substantially in the last few weeks. However, it is expected that feed prices will remain volatile and high for the year ahead, he added.

Shares of the company were down $8.37 at $29.54 in morning trade Monday on Nasdaq. They hit a low of $28.59 earlier.
