NorthWestern Energy reported financial results for the full year ended December 31, 2025. Net income attributable to shareholders was USD 181.1 million, or USD 2.94 per diluted share. Non-GAAP net income was USD 220.1 million, with non-GAAP earnings per share at USD 3.58. The company noted that the decrease in net income was primarily due to higher operating expenses, including a non-cash charge for the regulatory disallowance of certain Yellowstone County Generating Station capital costs, merger-related costs, increased depreciation, interest expense, Montana property tax tracker collections, non-recoverable Montana electric supply costs, and higher income tax expense. These impacts were partly offset by higher rates, electric transmission revenue, natural gas transportation revenues, and retail volumes. During the period, NorthWestern Energy highlighted the passage of House Bill 490 in Montana, providing clarity and limits around wildfire-related risks, which the company described as a critical achievement for customers, communities, and investors. The company also completed the Energy West acquisition and advanced several major initiatives to support reliable and affordable service across Montana, South Dakota, and Nebraska. An investor earnings webinar will be hosted on February 12, 2026.
