Risks

• Adverse determinations by regulators, such as denial of interim rates or final rates not consistent with a reasonable ability to earn allowed returns, could materially affect liquidity, results of operations, and financial condition.
• Potential adverse federal, state, or local legislation or regulation, including costs of compliance with existing and future environmental requirements, could impact financial performance.
• Wildfire damages in excess of liability insurance coverage could have a material effect on liquidity, results of operations, and financial condition.
• The impact of extraordinary external events and natural disasters, such as weather events (e.g., drought, lightning, wind, fire), could adversely affect liquidity, results of operations, and financial condition.
• Acts of terrorism, cybersecurity attacks, data security breaches, or other malicious acts could damage facilities or systems, or result in the release of confidential information.
• Supply chain constraints, high levels of inflation for products, services, and labor costs, and their impact on capital expenditures and operating activities, could affect the ability to safely and reliably serve customers.
• Changes in availability of trade credit, creditworthiness of counterparties, usage, commodity prices, fuel supply costs or availability due to higher demand, shortages, weather conditions, or transportation problems, may reduce revenues or increase operating costs.
• Unscheduled generation outages or forced reductions in output, maintenance or repairs, may reduce revenues, increase operating costs, or require additional capital expenditures.
• Adverse changes in general economic and competitive conditions in the U.S. financial markets and in service territories could negatively impact the business.
• If the Montana Public Service Commission (MPSC) chooses to accept intervenors' positions on contested issues or does not accept the Settlement Agreements in its final order, losses related to excess interim revenues collected will be incurred.
• Any difference between interim and final approved rates in Montana will be refunded to customers with interest; however, if final approved rates are higher than interim rates, the company will not recover the difference.
• Compliance with Environmental Protection Agency (EPA) greenhouse gas (GHG) and Mercury and Air Toxics Standards (MATS) Rules could require expensive upgrades at coal-fired facilities with potentially unachievable compliance dates or unproven technology, despite recent regulatory relief efforts.

Future Outlook

The company is initiating 2025 non-GAAP earnings guidance of $3.53 to $3.65 per diluted share, representing 4% to 7% EPS growth from the 2024 non-GAAP base year. It is affirming its long-term (five-year) diluted earnings per share growth guidance of 4% to 6% and a $2.7 billion capital investment plan for 2025-2029, which is expected to support rate base growth of 4% to 6%. The capital program is planned to be funded through cash from operations and secured debt issuances, with minimal cash taxes expected into 2028. The company remains committed to maintaining a dividend payout ratio within its targeted range of 60-70% over the long term, with earnings growth expected to exceed dividend growth until this ratio is achieved. An outcome in the Montana rate review is expected early in the fourth quarter of 2025, which is crucial for aligning rates with current service costs.
