Antitrust settlement clears path as utility pipeline grows
- The regulated Electric segment is the anchor, with a $1.9 billion capital plan aimed at 10% rate base growth.
- A $103.5 million settlement agreement removes a major antitrust risk from the Plastics segment.
- The utility large load pipeline expanded to 1,400 megawatts in the second quarter.
- Plastics is still a major cash source, but PVC pipe prices continue to normalize.
- Finn's view is mixed: good financial health, fair valuation, and slower overall growth.
A utility story with less legal risk
Otter Tail's main appeal is its regulated utility growth, funded largely by cash from its other segments. Management has a $1.9 billion 5-year capital plan meant to grow rate base at a 10% compound annual rate. The utility pipeline is expanding, with 1,400 megawatts of large load projects now identified and a new 15-year resource plan requesting 150 megawatts of new generation.
The bull case is that Otter Tail can fund this utility growth with cash from Plastics while Manufacturing recovers. That lowers the need to sell new stock, which can dilute current shareholders. The recent $103.5 million settlement of the PVC antitrust lawsuit removes a major legal overhang, making the funding path clearer.
The bear case centers on execution and timing. MISO Tranche 2.1 transmission work faces regulatory opposition and potential delays. Additionally, while the large load pipeline grew, investors are waiting to see how many of those 1,400 megawatts convert into signed agreements with financial guarantees.
Rates, pipes, and metal parts
Otter Tail makes money in three ways. Electric sells power to homes and businesses in parts of Minnesota, North Dakota, and South Dakota. Manufacturing sells custom metal fabrication and thermoformed or extruded plastic products. Plastics sells PVC pipe for water, wastewater, and related uses.
The Electric segment is the main moat. A regulated utility is a natural monopoly because it is not practical to build competing wires to the same customers. In exchange, regulators decide what Otter Tail can charge and how much return it can earn.
The non-utility businesses add cash and risk. Plastics earned unusually high profits after PVC pipe prices peaked in late 2022, but those prices are normalizing downward. Manufacturing is tied to economic cycles, recovering slowly as construction and recreational vehicle demand improve.
What the company sells
Regulated electric service
Otter Tail Power generates, transmits, and distributes electricity. This is the core business and the main source of stable earnings.
Utility capital projects
The $1.9 billion 5-year plan includes renewable generation, advanced metering, and grid work. These projects grow the rate base.
Long-range transmission
MISO Tranche 2.1 and JTIQ projects could extend growth into the 2032 to 2034 period. The 2025 10-K estimated Otter Tail's MISO investment near $1 billion.
BTD Manufacturing
BTD makes custom metal parts and assemblies. Sales are recovering alongside construction and recreational vehicle demand.
PVC pipe
The Plastics segment sells pipe used in municipal and rural water projects. It produces strong cash, but prices are coming down from peak levels.
Recent revenue mix
The mix reflects early 2026 operating revenue. Electric contributes roughly half, while Manufacturing and Plastics split the remainder, though Plastics generates a larger share of cash flow.
What could go wrong
Large load projects do not convert
Medium impact · Medium oddsThe large load pipeline reached 1,400 megawatts in Q2 2026. The question is whether these opportunities become signed deals. If they stall, the utility growth plan has less upside.
MISO Tranche 2.1 delays
High impact · Medium oddsOtter Tail's long-term bull case includes large transmission investments after 2030. Management has warned that political opposition and FERC complaints could delay these projects, pushing out future rate base growth.
PVC pipe profits keep normalizing
Medium impact · High oddsPlastics is generating cash, but average PVC pipe prices are falling from peak levels. Demand has been strong ahead of resin price increases, but that volume strength may not last.
Coal and rate recovery risk
Medium impact · Medium oddsCoyote Station remains an environmental watch item. The Minnesota rate case includes accelerated recovery tied to ending service from Coyote Station by December 2031. EPA action on the North Dakota SIP could also affect costs.
In one breath
Is Otter Tail mainly a utility?
Yes. The Electric segment is the core business and the main source of regulated growth. The company also owns Manufacturing and Plastics businesses, which make earnings more cyclical than a pure utility.
What happened to the PVC pipe lawsuit?
In Q2 2026, the company entered into a $103.5 million settlement agreement to resolve the U.S. PVC pipe antitrust litigation. This removes a major risk overhang pending final court approval.
Why are Plastics earnings falling?
PVC pipe prices rose to very high levels after 2022, then started to normalize. Prices have continued to drop, although strong sales volumes have partially offset the decline.
What should investors watch next?
Final court approval of the PVC settlement, progress on the 1,400 megawatt large load pipeline, and any FERC action on MISO Tranche 2.1 transmission projects.
