Material Changes vs. Prior Period
- Revenue Growth: Total revenues increased 6.6% to $497.6 million, driven by new rates, transmission revenues, and the acquisition of Colstrip interests, partially offset by lower retail volumes due to warmer weather.
- Profit Decline: Net income decreased 17.5% to $63.5 million. The decline was primarily attributed to higher operating expenses (including $3.4 million in merger-related costs and costs associated with new Colstrip ownership), increased depreciation, and higher interest expense.
- Utility Margin: The non-GAAP Utility Margin increased 7.2% to $352.0 million, reflecting the positive impact of base rate increases and the Colstrip Puget Interests acquisition, which offset volume headwinds.
- Segment Performance: Electric utility margin rose 12.0%, while Natural Gas utility margin fell 6.4% due to unfavorable weather reducing heating demand.
Outlook, Risks, and Management Commentary
- Pending Merger: The merger with Black Hills Corporation remains subject to regulatory approvals from FERC, MPSC, NPSC, and SDPUC. Shareholder approval was obtained in April 2026. Management anticipates closing in H2 2026.
- Colstrip Acquisitions: The company acquired interests in Colstrip Units 3 and 4 from Avista and Puget on January 1, 2026. While FERC approved cost-based rates for the Puget interests, the MPSC has suspended the 90/10 cost-sharing mechanism for Montana electric supply costs pending further review, creating uncertainty in cost recovery.
- Regulatory Matters: A Montana rate review resulted in a $30.9 million non-cash charge in Q4 2025 for disallowed capital costs related to the Yellowstone County Generating Station. The company has filed a Motion for Reconsideration.
- Data Center Growth: The company has signed development agreements for data centers in Montana with a combined expected load of 150 MW by late 2027, potentially growing to 1,500 MW by 2030.
- Capital Plan: Management targets a debt-to-total capital ratio of 50-55% and a dividend payout ratio of 60-70% of earnings per share.
Investor Verification Checklist
- Merger Closing Timeline: Verify the status of regulatory approvals (FERC, MPSC, NPSC, SDPUC) required to close the Black Hills merger in H2 2026.
- Colstrip Cost Recovery: Monitor the outcome of the MPSC's review of the PCCAM cost-sharing mechanism and the FERC rehearing request regarding Puget Interests rates.
- Montana Rate Review: Track the resolution of the Motion for Reconsideration regarding the $30.9 million disallowance for the Yellowstone County Generating Station.
- Weather Sensitivity: Assess the impact of warmer-than-average weather on Q1 retail volumes and the potential for volume recovery in subsequent quarters.
- Capital Expenditure Execution: Review the $116.1 million Q1 capex spend against the annual plan, particularly regarding the new 131 MW South Dakota gas facility and transmission projects.
