Is OTTR a Buy? What to Consider in 2026
Last updated July 2026
Short answer
The bull case for Otter Tail Corporation (OTTR) rests on Regulated utility rate-base growth: The Electric segment is the durable core, with earnings expected to grow around 14% in 2026 on a similar increase in average rate base. Revenue (TTM) is ~$1.29B. If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: The central risk is that plastics earnings fall faster or further than expected as PVC pipe prices continue resetting, pressuring consolidated EPS during the 2026 to 2028 transition. Whether OTTR is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.
Otter Tail Corporation is a diversified company headquartered in Fergus Falls, Minnesota, operating through three segments. Its Electric segment is a regulated utility that generates, transmits, and distributes power to customers across Minnesota, North Dakota, and South Dakota using coal, natural gas, wind, and solar. Its Manufacturing segment provides contract metal fabrication and other industrial products, and its Plastics segment makes PVC pipe through subsidiaries such as Northern Pipe Products and Vinyltech. Trailing-twelve-month revenue is roughly $1.29 billion, with the regulated utility providing predictable, rate-base-driven earnings and the two non-regulated segments adding cyclical upside and downside. The investment picture centers on a transition. During 2021 to 2023 the Plastics segment earned outsized profits as PVC pipe prices spiked, inflating total earnings well above the utility's normal contribution. As pipe prices reset lower, plastics earnings are stepping down (management expects them to normalize toward roughly $45 million to $50 million annually by 2028), while the regulated Electric segment grows its rate base and earnings. The market debate is whether utility and manufacturing growth can offset the plastics normalization, and how much of OTTR's earnings should be valued at a utility multiple versus a lower cyclical one.
What's the case for buying OTTR?
1. Regulated utility rate-base growth
The Electric segment is the durable core, with earnings expected to grow around 14% in 2026 on a similar increase in average rate base. Investment in transmission, renewables, and grid reliability across its three-state footprint gives visible, regulator-supported earnings that anchor the company. This is the piece the market values most like a traditional utility.
2. Plastics normalization
Plastics earnings surged during the PVC price spike and are now resetting lower as pipe prices decline. Management flagged a large step-down in 2026 and a target of roughly $45 million to $50 million in annual plastics earnings by 2028. How gracefully this segment lands is the single biggest swing factor for consolidated results.
3. Manufacturing and diversification
The Manufacturing segment (contract metal fabrication) adds industrial exposure and is guided to modest growth, though certain end markets remain soft. The three-segment mix gives OTTR more cyclical torque than a pure utility while the regulated arm smooths the ride.
4. Dividend and capital returns
Otter Tail has a long track record of paying dividends, currently around $2.31 per share annually, supported by utility cash flows and a strong balance sheet built up during the plastics boom. That balance-sheet cushion helps fund utility capital spending without heavy external financing.
What are the risks to OTTR?
The central risk is that plastics earnings fall faster or further than expected as PVC pipe prices continue resetting, pressuring consolidated EPS during the 2026 to 2028 transition. Commodity and end-market cyclicality in both plastics and metal fabrication add volatility that pure regulated utilities do not carry. Regulatory outcomes on rate cases, allowed returns on equity, and the pace of the energy transition can affect the Electric segment's growth. The stock can also be re-rated if investors decide to value a larger share of earnings at a lower cyclical multiple rather than a utility multiple. Weather, fuel costs, and interest rates are additional standard utility sensitivities.
How is OTTR valued? (as of July 2026)
Snapshot for OTTR as of July 2026, sourced from Yahoo Finance and may be delayed. Valuation figures move with price and earnings; verify the current numbers with your broker before deciding.
- Revenue (TTM): ~$1.29B
- Q1 2026 revenue: ~$347M
- Q1 2026 diluted EPS: ~$1.73
- 2026 EPS guidance: ~$5.22 to $5.62
- Market cap: ~$3.9B
- P/E (approx): ~14x
- Dividend / yield: ~$2.31/yr (~2.5%)
OTTR trades at a mid-teens P/E, below many pure regulated utilities, reflecting the market's discount on the cyclical plastics earnings that are normalizing lower. Q1 2026 came in ahead of expectations with EPS of roughly $1.73, and management affirmed full-year guidance of about $5.22 to $5.62. The valuation debate hinges on how much of the earnings base is durable utility versus fading plastics upside.
How do you decide if OTTR is a buy?
Rather than asking whether OTTR is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold OTTR indirectly through an index or sector ETF before adding more.

What does Otter Tail Corporation do?
+
Otter Tail is a diversified company with three segments: a regulated Electric utility serving Minnesota, North Dakota, and South Dakota, a Manufacturing segment focused on contract metal fabrication, and a Plastics segment that makes PVC pipe. The utility provides stable earnings while the other two add cyclical exposure.
Is OTTR a utility stock?
+
It is a hybrid. The Electric segment is a traditional regulated utility, but a meaningful share of profits comes from non-regulated plastics and manufacturing. That mix gives OTTR more earnings cyclicality than a pure utility, which is why it often trades at a lower multiple than regulated peers.
Why are Otter Tail's plastics earnings declining?
+
PVC pipe prices spiked during 2021 to 2023 and lifted plastics profits far above normal. As those prices reset lower, plastics earnings are stepping down. Management expects the segment to normalize toward roughly $45 million to $50 million in annual earnings by 2028.
How did OTTR perform in Q1 2026?
+
Otter Tail reported first-quarter 2026 revenue of about $347 million and diluted EPS of roughly $1.73, both up year over year and ahead of analyst expectations. Electric revenue rose on higher retail volumes while plastics pricing declined.
