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 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.
