Otter Tail Corporation reported 2025 diluted earnings per share of $6.55, with a consolidated return on equity of 16% on an equity ratio of 63%. The Electric segment grew operating revenue 8.1% and net income 7.3%, helped by higher sales volumes, fuel recovery and favorable weather, partly offset by higher depreciation and interest costs.
The Manufacturing segment saw operating revenue decline 8.2% and net income fall 15.8% as softer demand in key end markets weighed on volumes, though cost actions improved margins. Plastics segment operating revenue declined 8.8% and net income decreased 15.1% as PVC pipe prices fell from 2024 peaks, partly offset by higher volumes and lower resin costs.
Operating cash flow was $386.0 million, funding $288.1 million of capital expenditures, mainly in the Electric segment. For 2026, the company guides diluted EPS to $5.22–$5.62, with an expected return on equity of 11.5%–12.3% and a roughly balanced earnings mix between Electric and non‑electric businesses.
