Closing the plant - which makes brands including Grape-Nuts and Raisin Bran - will deliver “net pretax annual cash manufacturing cost savings of approximately $14m”, said the company, which said last month that it was "committed to addressing our excess capacity" and improving operational efficiency.
Post - which was spun off from Ralcorp last year and is now an independent, publicly traded company - manufactures its cereals at facilities in Battle Creek, Michigan; Jonesboro, Arkansas; and Niagara Falls, Ontario; as well as Modesto.
Its brands include Honey Bunches of Oats, Pebbles, Great Grains, Post Shredded Wheat, Post Raisin Bran, Grape-Nuts, and Honeycomb.
