Company Overview

Post Holdings is a St. Louis food holding company behind Honey Bunches of Oats, Fruity Pebbles, Grape-Nuts, Malt-O-Meal, Peter Pan, Rachael Ray Nutrish, Bob Evans side dishes, Michael Foods egg products and Weetabix. It was spun off from Ralcorp in February 2012 with founding Chairman and CEO William Stiritz, and Robert Vitale ran it as CEO from November 2014 until September 2026. It first entered the Fortune 500 in 2025. The company is headquartered in St. Louis, Missouri. Post Holdings traces its origins to C.W. Post creating Postum in 1895 in Battle Creek, Michigan, before being spun off from Ralcorp Holdings in 2012 by corporate architect William P. Stiritz as an aggressive consumer packaged goods holding company headquartered in St. Louis, Missouri.

Post makes money by manufacturing and selling packaged food through four segments. Post Consumer Brands sells branded and private-label cereal and granola (Honey Bunches of Oats, Pebbles, Malt-O-Meal), pet food (Rachael Ray Nutrish, Nature's Recipe, 9Lives, Kibbles 'n Bits) and Peter Pan peanut butter to grocery, mass and club retailers. Foodservice, run by Michael Foods, sells value-added egg products and potato products to restaurant chains, distributors and institutions. Refrigerated Retail sells Bob Evans side dishes, sausage and egg products to supermarkets. Weetabix sells cereal, muesli and protein shakes mainly in the United Kingdom. In Q3 fiscal 2026, Post Consumer Brands produced $974.2 million of the $1.948 billion in net sales and Foodservice produced $652.9 million.
