NorthWestern Energy Group reported mixed first-quarter 2026 financial results, with GAAP diluted EPS decreasing to $1.03 from $1.25 year-over-year, primarily due to retail volumes and increased operating expenses. However, adjusted non-GAAP diluted EPS increased to $1.31 from $1.22. The company affirmed its 2026 earnings guidance range of $3.68 to $3.83 per diluted share, signaling stability in its outlook despite the GAAP decline. Significant progress was made on the pending merger with Black Hills Corporation, including shareholder approvals and constructive settlement agreements with key intervenors in Montana, Nebraska, and South Dakota, moving closer to an anticipated second-half 2026 closing. Additionally, the passage of South Dakota's Senate Bill 36 provides crucial wildfire liability protections, mitigating a significant operational risk. The company also declared a quarterly dividend of $0.67 per share, a slight increase from the prior year.
