This page follows insider dealings at Otter Tail Corp as filed with SEC (Form 4), a company from the Energy sector based in Fergus Falls, United States. The group dates from 1909. 16 insiders have disclosed 29 filings since 18 October 2025.
The flow runs one way only: 3 sales worth €342k, from 1 insider, and no purchase. At €283k, the sale published on 11 August 2026 by Knutson Paul l is the largest of the period (0.0086% of market cap).
Compared with its exchange (5,458 companies, median 22 filings), a count of 29 filings is above the norm. Since 2016, the database holds no purchases and 5 sales by insiders of the company. On the fundamentals side, the SEC filing (10-K/A) for the period ending 31 December 2025 lists revenue at 1.30 bn USD and net income at 275.9 m USD; the dividend was 2.10 USD per share.
Between a trade and the moment it shows up on SEC (Form 4), the median delay is 1 day. The legal deadline for a Form 4 is two business days after the transaction. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning.

About Otter Tail Corp
Otter Tail Corp. (Nasdaq: OTTR) is a U.S.-listed diversified company headquartered in Fergus Falls, Minnesota, in the United States. For French-, Belgian-, and Swiss-based investors, it stands out as a hybrid profile that combines a regulated electric utility with industrial manufacturing and plastics operations. This mix gives the company a balance between earnings visibility from regulated assets and incremental growth potential from its non-utility businesses. According to the company’s corporate profile, Otter Tail is built around a regulated electric platform and complemented by manufacturing and plastics businesses, with a mission to deliver value to shareholders, customers, and employees. ([ottertail.com](https://www.ottertail.com/investors/corporate-profile/default.aspx))
The core of the investment case is Otter Tail Power, the regulated utility subsidiary. It serves customers across parts of the Upper Midwest and is actively investing in grid reliability, transmission and distribution assets, renewable generation, battery storage, and related technology upgrades. Management has highlighted a multi-year capital plan that supports growth in the regulated rate base, with solar, wind repowering, and storage among the key investment themes. For investors, this regulated utility base is an important anchor because it typically provides steadier cash generation than a pure industrial model.

Beyond the utility franchise, Otter Tail also owns manufacturing businesses and a plastics segment. This diversification is a defining feature versus many U.S. utilities that remain almost entirely regulated. The industrial platform adds exposure to end-market demand, pricing dynamics, and operating leverage, while also contributing cash flow and helping fund utility investment needs. Management has repeatedly emphasized cost discipline, execution, and the ability of the non-regulated portfolio to produce accretive returns alongside the electric business. ([ottertail.com](https://www.ottertail.com/investors/corporate-profile/default.aspx))
Geographically, Otter Tail remains concentrated in the northern United States, with a practical operational footprint centered in the Midwest. That regional focus supports local utility relationships and a more stable customer base, but it also means results can be influenced by weather patterns, regulatory outcomes, and infrastructure recovery needs. Recent updates show the company executing well: in the first quarter of 2026 it affirmed full-year EPS guidance, secured approval of its fully settled South Dakota rate case, implemented new base rates in April, completed its wind repowering project, and finished the second phase of the Vinyltech expansion, adding 15% more production capacity. ([ottertail.com](https://www.ottertail.com/investors/news/news-details/2026/Otter-Tail-Corporation-Announces-First-Quarter-Earnings-and-Affirms-2026-EPS-Guidance/default.aspx))
From a market perspective, OTTR trades on the Nasdaq in the United States. In 2025, the company reported $1.304 billion of revenue, $276 million of net income, and diluted EPS of $6.55, while also maintaining a growing dividend profile. For European investors seeking U.S. listed income-oriented equities with a utility core and industrial upside, Otter Tail offers a differentiated combination of regulated earnings, capital investment visibility, and diversified cash generation.
