Material Changes vs. Prior Period
- Revenue Growth: Total revenues increased 14.6% in Q2 2026 and 10.0% YTD 2026 compared to the prior year. Growth was driven by new base rates, increased retail volumes (partly due to favorable weather in South Dakota and customer growth), and the acquisition of Colstrip Units 3 and 4 interests.
- Net Income Variance: Q2 2026 net income rose 17.8% to $25.0 million. However, YTD 2026 net income declined 9.9% to $88.5 million. The YTD decline was primarily due to unfavorable weather impacts on retail volumes, higher operating expenses (including merger costs and Colstrip operating costs), and increased interest expense.
- Expense Increases: Operating expenses (excluding fuel) rose 15.4% in Q2 and 16.1% YTD. Key drivers included electric generation maintenance (linked to Colstrip acquisitions), depreciation, merger-related costs ($3.3M in Q2, $6.7M YTD), and wildfire mitigation expenses.
- Interest Expense: Net interest expense increased 11.2% in Q2 and 10.3% YTD due to higher borrowings and interest rates, partially offset by higher capitalization of Allowance for Funds Used During Construction (AFUDC).
Guidance, Outlook, and Risks
- Merger with Black Hills: The transaction is an all-stock merger of equals. Regulatory approvals have been received from the SEC, FERC, Nebraska PSC, and South Dakota PUC. The Montana PSC approval is pending a final order following a hearing in May 2026. Closing is anticipated by year-end 2026.
- Colstrip Acquisitions: NWE acquired interests in Colstrip Units 3 and 4 from Avista and Puget on January 1, 2026. While the Puget interests are expected to be cost-neutral via power sales contracts, the Avista interests face cost recovery challenges as power prices were insufficient to offset operating costs in the first half of 2026. A temporary tariff waiver was approved by the MPSC.
- Regulatory Matters: The Montana PSC suspended the 90/10 cost-sharing mechanism of the Power Cost and Credit Adjustment Mechanism (PCCAM) pending review. NWE filed a motion for reconsideration regarding capital cost prudence for the Yellowstone County Generating Station.
- Large New Loads: NWE is pursuing data center development agreements (Sabey, Atlas, Quantica) with a combined potential load of up to 1,500 MW by 2030. A new Large New Load tariff rule was filed with the MPSC in March 2026.
- Capital Projects: A 131 MW natural gas facility in Aberdeen, South Dakota, is planned to meet regional capacity needs by 2030, with estimated costs of $300 million. $42.3 million has been recorded for non-refundable milestone payments.
- Risks: Key risks include delays in merger regulatory approvals, failure to recover costs associated with Colstrip acquisitions, adverse weather impacts on volumes, and potential wildfire liabilities (though South Dakota legislation passed in March 2026 limits strict liability).
Investor Verification Checklist
- Merger Closing Timeline: Verify the status of the final Montana Public Service Commission (MPSC) order required to close the Black Hills merger.
- Colstrip Cost Recovery: Monitor the outcome of the MPSC's review of the PCCAM tariff waiver and the ability to recover operating costs for the Avista interests.
- Capital Expenditure Execution: Track progress on the $300 million South Dakota gas facility and the North Plains Connector transmission project.
- Weather Sensitivity: Assess the impact of weather normalization on YTD 2026 revenue and volume trends, particularly in Montana and Nebraska.
- Debt Maturities: Review the schedule of long-term debt maturities and refinancing needs, given the increase in interest rates.
