MINNEAPOLIS — General Mills Inc. has closed its acquisition of natural food company Annie’s Inc.

General Mills said Tuesday that it completed its tender offer to buy Annie’s for $46 per share, or about $820 million. The deal was announced early last month.

Annie’s shares ceased trading on the New York Stock Exchange at the end of Monday’s session.

Plans call for Berkeley, Calif.-based Annie’s to join General Mills’ U.S. natural and organic products portfolio, which includes the Cascadian Farm, Muir Glen, Larabar and Food Should Taste Good brands.

Annie’s offers more than 145 products, and its offerings are sold in over 35,000 retail locations in the United States and Canada. Products include pastas, snacks, snack and meal kits, frozens, dressings and oils, condiments and sauces, and special diet items. The company’s sales totaled $204 million in its fiscal year ended in March.
