OTTER TAIL CORP
Guided by a long history of delivering energy and value-added services, Otter Tail Corp operates primarily through regulated electric utility and related infrastructure businesses, ensuring core products such as electricity generation, transmission, distribution, and energy management solutions reach largely rural residential, commercial, and industrial customers across the Upper Midwest; this orientation reflects its legacy SIC 4911 electric services pedigree even as it adapts to broader demand-side technologies. With energy affordability and reliability at the heart of its value proposition, the company works closely with public utility commissions and partners to balance investment in grid resilience while navigating material risks tied to fluctuating fuel costs, extreme weather events, and stringent regulatory oversight on emissions, rate design, and capital deployment. Stakeholders should take note of the company’s governance posture and filings, including the most recent submission available through its SEC profile, and reference CIK 75129 when monitoring compliance activity; for up-to-the-minute insight, view live SEC filings on Earnings Feed.
