Negatives

• Operating, administrative, and general costs increased, including merger-related costs and costs associated with additional ownership interests in Colstrip Units 3 and 4.
• Depreciation expense and interest expense also increased compared to the prior year period.
• Merger-related costs incurred were $3.3 million for the quarter and $6.7 million year-to-date.
• Power prices in the Pacific Northwest were insufficient to recover operating expenses associated with the Avista Interests in Colstrip.
• A $30.9 million non-cash charge was recorded in Q4 2025 due to a regulatory disallowance of a portion of capital costs related to the construction of Yellowstone County Generating Station.

Risks

• The pending merger with Black Hills Corporation is subject to risks including potential delays in consummation, unexpected conditions on regulatory approvals, and the possibility that anticipated benefits may not be realized.
• Adverse determinations by regulators, such as denial of interim rates or failure to approve cost recovery for Colstrip interests, could materially affect liquidity and financial condition.
• Wildfire damages in excess of liability insurance coverage pose a risk.
• The ability to attract and serve large new load customers depends on supportive regulatory and legislative actions.
• Supply chain constraints, inflation for products, services, and labor costs could impact capital expenditures and operations.
• Unscheduled generation outages or forced reductions in output could reduce revenues and increase operating costs.
• Cybersecurity attacks or data security breaches could cause damage to facilities or result in the release of confidential information.

Future Outlook

The company affirmed its 2026 non-GAAP earnings guidance range of $3.68 to $3.83 per diluted share. It also reaffirmed its long-term diluted earnings per share growth guidance of 4% to 6% based on a 2024 adjusted diluted non-GAAP EPS baseline of $3.40. The $3.2 billion capital investment plan for 2026-2030, expected to support rate base growth of 4% to 6%, was also affirmed. Equity issuances are expected beginning in 2027 to fund South Dakota generation investment.

Management Comments

• "We are pleased to report solid results for the quarter and exciting progress on the merger," said President and CEO Brian Bird.
• "In the meantime, we remain focused on executing our strategic priorities, delivering safe, reliable, and affordable service to our customers, and integration planning to position the combined company for long-term success."

Industry Context

StockSavvy.ai notes that NorthWestern Energy's Q2 2026 results and merger progress align with broader industry trends of consolidation and strategic investment in infrastructure to meet growing energy demands, particularly from large-load customers like data centers.

Comparison to Industry Standards

• NorthWestern Energy's affirmed long-term EPS and rate base growth targets of 4%-6% are generally in line with stable, mature utility companies, though potentially lower than some growth-oriented utilities in rapidly expanding markets.
• The company's focus on a $3.2 billion capital investment plan over five years to support rate base growth is a significant undertaking, comparable to other utilities investing heavily in grid modernization and new generation.
• The merger with Black Hills Corporation, if completed, would create a larger entity with a combined rate base of approximately $11 billion, positioning it more competitively against larger regional and national utilities.

Legal Proceedings

• Two MPSC commissioners appealed the FERC's decision regarding the Puget Interests to the Ninth Circuit; NorthWestern has intervened in the case.

Stakeholder Impact

• Shareholders: Benefit from affirmed earnings guidance, dividend declaration, and potential value creation from the merger.
• Customers: Benefit from continued focus on safe, reliable, and affordable service; potential for enhanced services through merger scale; regulatory mechanisms aim to recover costs.
• Employees: Merger integration planning and focus on operational execution are key.
• Creditors: Increased liquidity and affirmed financial targets support creditworthiness.

Next Steps

• Await final order from the Montana Public Service Commission for merger approval.
• Host investor conference call and webcast on July 30, 2026, to review financial results.
• File wildfire mitigation plan with the South Dakota Public Utilities Commission in the third quarter of 2026.
• Anticipate the merger transaction closing by year-end 2026.
• Begin equity issuances in 2027 to fund South Dakota generation investment.

Key Dates

Recommendation

The company is performing well operationally and making good progress on a transformative merger. However, the successful completion of the merger is still subject to regulatory approval, and potential integration challenges and market reception warrant a cautious 'hold' stance until the transaction is finalized and its benefits are more clearly realized.
