Impact Evaluation

• Earnings and Guidance: The company reported Q3 2025 GAAP EPS of $0.62 and affirmed its 2025 earnings guidance range of $3.53 to $3.65 per diluted share. This provides investors with confidence in the company's operational stability and financial outlook.
• Merger Progress: NorthWestern has filed joint applications with regulators in Montana, South Dakota, and Nebraska for its all-stock merger of equals with Black Hills Corporation. This is a critical step toward the anticipated closing in the second half of 2026 and a major catalyst for the company's future structure and valuation.
• Capital Return: The announcement of a $0.66 per share quarterly dividend reinforces the company's commitment to returning capital to shareholders.
• Future Growth: The submission of a project for a new 131 MW natural gas generating facility in South Dakota (approx. $300M cost) signals a clear strategy to address growing energy demands and invest in future rate base growth, which is a primary driver of earnings for regulated utilities.
