Key Financial Metrics

Note: Utility Margin is defined as Operating Revenues less fuel, purchased supply, and direct transmission expense.

Material Changes vs. Prior Period

• Revenue Growth: Total revenues increased 12.1% in Q3 2025 compared to Q3 2024, driven by higher retail rates, increased customer usage (favorable weather in South Dakota), and higher transmission revenues.
• Net Income Decline: Despite revenue growth, Net Income decreased 18.3% in Q3 2025. This was primarily due to:
  • Merger Costs: $7.6 million in merger-related transaction expenses.
  • Higher Expenses: Increases in depreciation ($5.8M), operating and maintenance costs, and interest expense ($5.0M higher due to higher borrowings and rates).
  • Tax Impact: The effective tax rate rose to 18.7% in Q3 2025 from a benefit of (7.3)% in Q3 2024, largely due to the absence of a prior-year gas repairs safe harbor method change benefit.
• Segment Performance: The Electric segment generated $61.3 million in net income for Q3 2025, while the Gas segment reported a net loss of $14.7 million, primarily due to higher operating costs and interest allocation.
• Acquisition: Completed the acquisition of Energy West Operations in July 2025 for approximately $35.9 million, adding 33,000 natural gas customers.

Guidance, Outlook, and Risks

• Merger with Black Hills: The company is proceeding with an all-stock merger (0.98 Black Hills shares for 1 NWE share). Closing is expected in H2 2026, subject to regulatory approvals (FERC, state commissions) and shareholder votes. Risks include regulatory delays, failure to realize synergies, and potential termination fees ($100 million).
• Regulatory Matters:
  • Montana Rate Review: Interim rates were implemented in July 2025. A final order is expected in Q4 2025. There is a risk of refunding excess interim revenues if final rates are lower.
  • Colstrip Acquisitions: NWE expects to acquire interests in Colstrip Units 3 and 4 from Avista and Puget Sound Energy on January 1, 2026. The company has filed for cost recovery mechanisms to offset estimated $48 million in annual incremental operating costs.
• Capital Expenditures: YTD 2025 capital expenditures were $374.5 million. The company plans to submit a project for a 131 MW natural gas facility in South Dakota (approx. $300 million cost) to meet regional capacity needs by 2030.
• Dividends: Declared dividends of $0.66 per share for Q3 2025. The company targets a long-term payout ratio of 60-70% of earnings per share.

Investor Verification Checklist

• Merger Closing Conditions: Verify the status of regulatory approvals (FERC, MPSC, NPSC, SDPUC) and shareholder votes required to close the Black Hills merger.
• Montana Rate Case Outcome: Monitor the final order from the Montana Public Service Commission (MPSC) expected in Q4 2025 to assess potential refunds of interim revenues.
• Colstrip Cost Recovery: Confirm the MPSC's decision on the PCCAM tariff waiver request filed in August 2025 to recover operating costs for the Avista interests.
• Interest Rate Exposure: Review the impact of rising interest rates on the company's debt service, given the increase in interest expense and new debt issuances.
• Utility Margin vs. GAAP Net Income: Analyze the divergence between the strong Utility Margin growth (+16.6%) and the decline in GAAP Net Income to understand the impact of non-operating and one-time costs.
