Negatives

• While the Colstrip acquisition is at no cost, the plant is coal-fired, and NWE will own 55% of Units 3 & 4, which could present long-term environmental and regulatory challenges despite the "bridge to cleaner energy" narrative.

Risks

• Actual future business and financial performance may differ materially and adversely from expectations due to various factors listed in SEC filings.
• Financing plans are subject to change, and incremental capital opportunities may require equity financing, potentially impacting shareholder value.

• The disbursement of federal grants for projects like the North Plains Connector can be subject to political and regulatory delays, as evidenced by the recent Executive Order.
• While the Montana Wildfire Bill provides legal protections, the company still faces wildfire risks, and costs beyond authorized rates (up to $95 million over 5 years) may require deferral treatment.
• Achieving net-zero emissions by 2050 requires balancing affordability, reliability, and sustainability, and may necessitate carbon offsets and the development of new loweror no-carbon emitting resources, which will take time and investment.
