Material Changes vs. Prior Period
- Revenue Decline: Consolidated revenues decreased 3.7% in Q3 and 3.1% YTD. This was driven by a 13.9% drop in Plastics segment sales prices and an 8% volume decline in the Manufacturing segment due to soft demand in agriculture and recreational vehicle markets.
- Electric Segment Growth: The Electric segment saw revenue increases of 6.3% in Q3 and 8.4% YTD, fueled by higher wholesale sales volumes (up 124% in Q3) and increased fuel recovery revenues.
- Profitability: Net income decreased 8.4% in Q3 and 9.2% YTD. Operating income fell 10.2% in Q3, primarily due to lower revenues in non-utility segments and higher production fuel costs in the Electric segment.
- Tax Rate Reduction: The effective tax rate dropped to 14.1% in Q3 (from 17.9% in 2024) and 14.0% YTD (from 18.8%), largely due to increased Production Tax Credits (PTCs) from wind generation assets.
- Debt Issuance: In 2025, the Company issued $100 million in new long-term debt (Series 2025A and 2025B notes) to refinance short-term borrowings and fund capital projects.
Guidance, Outlook, and Risks
- Regulatory Filings:
- Minnesota: Filed a request on Oct 31, 2025, for a $44.8M annual revenue increase (17.7%), including accelerated recovery of Coyote Station investments. Interim rates of $31.8M are requested to begin Jan 1, 2026.

- Capital Expenditures: Anticipated total capital expenditures for 2025 are $321 million, with the Electric segment accounting for $300 million (renewables, transmission, distribution).
- Legal Contingencies: The Company is facing putative class action lawsuits in the U.S. and Canada regarding alleged antitrust violations in the PVC pipe market. A DOJ investigation is also ongoing. The Company states it cannot currently estimate the range of reasonably possible losses.
- Macro Risks: Management cites risks related to U.S. trade tariffs, inflation, and potential supply chain disruptions impacting the Manufacturing segment.
Investor Verification Checklist
- Antitrust Litigation Exposure: Verify the status of the PVC pipe antitrust lawsuits and DOJ investigation, as potential liabilities could be material and are currently unquantified.
- Rate Case Outcomes: Monitor the approval status of the Minnesota and South Dakota rate cases, which are critical for future revenue recovery and cash flow stability.
- Plastics Pricing Trends: Assess whether the 14% decline in PVC sales prices stabilizes, as this segment remains a significant profit driver despite volume increases.
- Wind Generation PTCs: Confirm the sustainability of the lower effective tax rate driven by Production Tax Credits from wind repowering projects.
- Debt Covenants: Review compliance with financial covenants (debt-to-capitalization ratios) given the recent issuance of $100M in new debt.
