Material Changes vs. Prior Period
- Revenue Growth: Consolidated revenues increased 2.9% year-over-year, driven by a 10.8% increase in the Electric segment due to rate increases and higher sales volumes, partially offset by a 13.5% decline in the Plastics segment due to lower average sales prices.
- Profitability: Net income rose 6.6% to $72.6 million. The Electric segment net income surged 42.7% to $35.3 million, while the Manufacturing segment net income increased 179.6% to $4.3 million. The Plastics segment net income declined 24.2% to $32.9 million.
- Capital Spending: Capital expenditures jumped significantly to $185.3 million (up $127.3 million), primarily due to accelerated procurement of solar panels for the Abercrombie project and timing of utility investments.
- Tax Impact: The effective tax rate dropped to 6.3% from 12.9%, largely due to increased Production Tax Credits (PTCs) from wind generation assets following the completion of repowering projects.
- Debt Issuance: The company issued $100 million in new long-term debt (Series 2026A Notes) in March 2026 to fund capital projects and repay short-term borrowings.
Outlook, Risks, and Management Commentary
- Regulatory Matters:
- South Dakota: A rate case settlement was approved in March 2026, granting a 7.7% revenue increase effective April 1, 2026, with a moratorium on base rate increases until December 2029. Interim rate refunds of $1.3 million will begin in May 2026.
- Minnesota: Interim rates effective January 1, 2026, provide an 11.3% revenue increase. The final case includes a request for accelerated recovery of Coyote Station investments.
- Legal Contingencies: The company is facing multiple class-action lawsuits and a DOJ investigation regarding alleged antitrust violations in the PVC pipe industry (price-fixing via information exchange). The company states it cannot currently estimate the financial impact, though it believes it has factual and legal defenses.
- Market Risks: The Plastics segment faces continued pressure from declining PVC pipe prices, though demand was supported by inventory stocking ahead of potential resin cost increases. The Electric segment remains sensitive to weather patterns (heating degree days were below normal in Q1 2026).
- Liquidity: Total available liquidity stands at $658.9 million, comprising $348.4 million in cash and $310.5 million in available credit facilities. The company remains in compliance with all financial covenants.
Investor Verification Checklist

- Track the Plastics segment pricing trends to assess if the multi-year decline in PVC prices has stabilized.
- Review the timing of capital expenditures for the Abercrombie Solar project and its impact on future cash flows.
- Confirm the Production Tax Credit (PTC) realization rates for wind assets following the Q1 2026 repowering completion.
