Diamond Hill Capital Management, LLC on Ameren Corporation

Thesis

Diamond Hill added Ameren for a combination of regulated-utility stability and long-term growth. The business benefits from a supportive regulatory environment and a strong balance sheet. Its projected rate-base expansion should provide a visible source of earnings growth. The holding introduces an essential-infrastructure compounder into the broader large-cap value portfolio.

“its attractive rate base growth outlook should also support long-term growth.”
