NorthWestern Energy Group to Combine With Black Hills

The two utilities framed the merger as a scale-and-investment play aimed at data-center-driven power demand.

The proposed combination of NorthWestern Energy Group, Inc. (NWE) and Black Hills (BKH) was described by the companies as a highly attractive value-creation opportunity that would increase scale, growth, and investment capacity, including addressing growing energy demand from data centers.

The two utilities presented the combination as a way to expand investment resources to address growing energy demand, including from data centers. That framing sits alongside a year in which Black Hills was already spending heavily on its own plant. In the nine months ended September 30, 2026, the company recorded $756.0 million of property, plant and equipment additions, up from $550.2 million a year earlier.

Black Hills reported revenue of $1,699.6 million for that nine-month period, compared with $1,674.5 million in the year-ago stretch. Operating income was $397.1 million. Net income available for common stock was $210.2 million, or $2.76 a share on a diluted basis.

For the three months ended September 30, 2026, revenue was $466.1 million and operating income was $98.1 million. Diluted earnings were $0.54 a share.

The balance sheet at September 30, 2026 showed total assets of $11.14 billion, with property, plant and equipment, net, of $8.78 billion. Long-term debt, net of current maturities, was $3.99 billion. Cash and cash equivalents stood at $18.2 million.

Operating cash flow for the nine months ended September 30, 2026 was $542.6 million. Financing included $398.8 million of proceeds from refundable advances for construction and $300.0 million of long-term debt repayments. Dividends paid on common stock were $160.2 million.

NorthWestern and Black Hills have already been flagging the proposed transaction in investor materials, including statements about anticipated benefits, expected timing, and the combined company’s plans after closing. Those decks also carry the usual caution that actual results may differ from the companies’ current expectations.

The combination is still subject to the customary closing conditions that accompany a utility merger of this kind, including regulatory approvals and the other hurdles the companies have listed in their transaction materials. Until those conditions clear, the scale-and-investment case the two firms put forward remains a plan rather than a closed deal.
