NorthWestern Energy reported third-quarter 2026 net income of $30.7 million, or $0.50 per diluted share, down from $38.2 million, or $0.62, a year earlier, mainly due to a $6.1 million net loss tied to its added Colstrip Units 3 and 4 interests, plus higher depreciation and interest expense. The company affirmed its 2026 non-GAAP earnings guidance of $3.68 to $3.83 per diluted share, but the guidance is standalone and will no longer apply if the pending Black Hills merger closes, which the company expects by year-end 2026.

Adjusted non-GAAP diluted EPS was $0.58 vs. $0.79 a year earlier; 2026 guidance of $3.68 to $3.83 per diluted share affirmed
