Post, which is based in St. Louis, also makes nutrition drinks and a variety of store-brand products including pasta and peanut butter. It said Monday that it expects about $1.07 billion in revenue for the fiscal quarter that ended Dec. 31. That includes some results from the company’s acquisitions of the PowerBar and Musashi brands as well as American Blanching Co.

That forecast matches Wall Street expectations, according to the data firm FactSet.

Shares of Post Holdings closed at $41.44 on Friday and have fallen about 25 percent over the past year.
