The Wall Street Journal reports St. Louis-based Ralcorp Holdings is about to buy the nation’s number three cereal maker – Post.

Neither Ralcorp nor Kraft Foods, the present owner of Post, has commented. The Journal says Ralcorp will pay $2.8-Billion. Post has 14 percent of the United States cereal market. Kellogg has 34; General Mills, 30.

The deal is expected to hike Ralcorp’s revenue by about half.
