Pinnacle Entertainment Inc. said the acquisition would save it at least $40 million a year and boost earnings.
Pinnacle has casinos in Louisiana, Missouri and Indiana. It's developing another property in Ohio, and also has a racetrack in the state. Ameristar's holdings include casinos in Missouri, Iowa, Colorado, Mississippi, Indiana and Nevada. If the two companies had already been combined into one, it would have generated $2.4 billion in revenue in the 12 months through September, Pinnacle said.
