NorthWestern Energy Group reported mixed first quarter 2026 results while advancing a major merger and growth projects. GAAP diluted EPS was $1.03 versus $1.25 a year ago as net income fell to $63.5 million from $76.9 million, driven by weaker retail volumes and higher operating, merger, Colstrip and depreciation costs.
Non-GAAP diluted EPS rose to $1.31 from $1.22, reflecting adjustments for unfavorable weather, merger costs, PCCAM changes and Avista Colstrip interests. Revenue increased to $497.6 million from $466.6 million, and utility margin grew to $352.0 million from $328.4 million, helped by Montana electric base rate increases and Puget Colstrip margins.
The company affirmed 2026 non-GAAP EPS guidance of $3.68–$3.83 per diluted share and long‑term EPS and rate base growth of 4%–6%, supported by a $3.2 billion 2026‑2030 capital plan and a record $683 million 2026 capital program. A quarterly dividend of $0.67 per share is payable June 30, 2026.
NorthWestern highlighted progress on its all‑stock merger of equals with Black Hills Corporation, including shareholder approvals, regulatory settlements in Montana, Nebraska and South Dakota, and expiration of the Hart‑Scott‑Rodino waiting period, with closing targeted in the second half of 2026. The company also detailed Colstrip acquisitions, South Dakota wildfire liability reforms, data center development agreements and a planned $300 million, 131 MW South Dakota gas plant, alongside a $150 million bond issuance at 5.51% to refinance $60 million of 2.80% bonds.
NorthWestern Energy Group reported first-quarter 2026 net income of $63.5 million, down from $76.9 million a year earlier, as higher operating, merger-related, Colstrip and depreciation costs and warmer weather more than offset new rates and stronger transmission revenue.
Total revenues rose to $497.6 million from $466.6 million, and non‑GAAP utility margin increased to $352.0 million from $328.4 million, driven mainly by higher electric base rates and margin from the acquired Puget Colstrip interests. However, electric and natural gas retail volumes fell on milder winter conditions, pressuring earnings.
