NorthWestern Energy Reports $25M Net Income for Q2 2026, Plans Merger with Black Hills Corporation

NorthWestern Energy Group, Inc. reported a consolidated net income of $25.0 million for the three months ended June 30, 2026, an increase from $21.2 million in the same period last year. This growth was attributed to higher retail volumes and new rates, which were partially offset by increased operating, administrative, and general costs, including merger-related expenses and costs associated with additional ownership interests in Colstrip Units 3 and 4. For the six months ended June 30, 2026, net income was $88.5 million, down from $98.2 million in the prior year, primarily due to similar cost pressures and lower retail volumes.

Total revenues for the second quarter of 2026 reached $392.6 million, a 16.0% increase from $342.7 million in the same quarter of 2025. Electric revenues rose to $324.3 million, up from $279.5 million, while gas revenues increased to $68.3 million from $63.2 million. The company’s operating expenses also grew, totaling $328.4 million for the quarter, compared to $281.9 million in the previous year, driven by higher fuel costs and increased administrative expenses.

Strategically, NorthWestern Energy is in the process of merging with Black Hills Corporation, a transaction that was unanimously approved by both companies' boards and is expected to close by the end of 2026, pending regulatory approvals. The merger aims to create a stronger entity with enhanced operational capabilities and financial stability. During the first half of 2026, the company incurred $6.7 million in merger-related costs, which were included in administrative expenses.

Operationally, NorthWestern Energy serves approximately 850,300 customers across Montana, South Dakota, Nebraska, and Yellowstone National Park. The company reported an increase in customer counts and retail volumes, particularly in the electric segment, which benefited from favorable weather conditions in South Dakota. However, the natural gas segment experienced a decline in retail volumes due to unfavorable weather in Nebraska. The company also completed acquisitions of interests in Colstrip Units 3 and 4, which are expected to enhance resource adequacy for its customers.

Looking ahead, NorthWestern Energy anticipates continued growth driven by infrastructure investments and strategic initiatives, including the development of new energy resources and enhancements to its grid. The company remains focused on achieving a net-zero carbon emissions goal by 2050 while managing its capital expenditures and maintaining a strong balance sheet. The ongoing merger with Black Hills is expected to further bolster its market position and operational efficiency.
