NorthWestern Energy Group (NASDAQ:NWE) reported a decline in first-quarter net income as the utility digested costs associated with its high-profile "megamerger" with Black Hills and increased its stake in one of the region's largest power plants.
The company posted GAAP net income of $63.5 million, or $1.03 per diluted share, down from $76.9 million, or $1.25 per share, in the same period last year.
The drop was primarily driven by administrative and general costs linked to the pending all-stock merger with Black Hills, alongside higher interest and depreciation expenses.
However, on a non-GAAP basis—which strips out merger-related items and one-off costs—net income rose to $80.6 million, or $1.31 per share, beating the prior year's $1.22.
A significant operational shift occurred on January 1, 2026, when NorthWestern officially acquired an additional 592 megawatts of the Colstrip power plant at no purchase price.
By taking over shares previously held by Puget Sound Energy and Avista, NorthWestern now holds a 55% majority stake in the facility.
While the acquisition increases operating costs in the near term, management noted it provides a critical "dependable bridge" for Montana’s energy security during the clean-energy transition.
Meanwhile, the utility’s strategic roadmap reached several milestones during the quarter.
Shareholders of both NorthWestern and Black Hills have approved all merger proposals.
The company also reached constructive settlement agreements with key regulatory intervenors in Montana, Nebraska, and South Dakota, clearing a significant hurdle for the tie-up.
NorthWestern also affirmed its record $683 million capital plan for 2026, part of a long-term strategy to drive a 4% to 6% rate base growth rate.
Elsewhere, the board announced a quarterly dividend of $0.67 per share, payable June 30, 2026.
The company also reaffirmed its full-year 2026 earnings guidance range of $3.68 to $3.83 per diluted share, signaling confidence that the efficiencies from the upcoming merger will offset the integration headwinds.
