Future Outlook

Management Comments

• "The first quarter included several important developments across our regulatory and strategic priorities."
• "In South Dakota, the signing of Senate Bill 36 into law provided greater clarity around wildfire-related liabilities and strengthened our ability to manage risk associated with critical energy infrastructure, aligning South Dakota with similar wildfire liability protections enacted in Montana last year."
• "In Montana, we also submitted our Large New Load tariff rule proposal to the Public Service Commission—an important step in protecting existing customers while supporting long-term energy investment and economic development in the state."
• "Together, these milestones meaningfully advance us toward a targeted second-half 2026 closing of the transaction."
• "We are committed to ensuring that shareholders will be afforded the same rights and opportunities to participate at our virtual meeting as they would in person."
• "We are committed to maintaining a dividend payout ratio within our targeted range of 60-70% over the long term."

Industry Context

StockSavvy.ai notes that NorthWestern Energy's Q1 2026 results reflect typical utility sector challenges such as weather impacts and rising operating costs, while also highlighting strategic progress in regulatory matters and merger integration. The focus on large new load customers like data centers aligns with broader industry trends of increasing demand from energy-intensive industries.

Comparison to Industry Standards

• NorthWestern Energy's residential electric and natural gas bills are reported to be below the national average, indicating affordability relative to industry peers.
• The company's System Average Interruption Duration Index (SAIDI) performance in 2024 and 2025 ranked in the second quartile compared to other utilities, suggesting reliability that meets or exceeds many industry standards, particularly given its rural service territory.
• The company's carbon-free supply portfolio of 52% exceeds the U.S. national average of 41% for electric power generation, positioning it favorably in terms of sustainability compared to industry benchmarks.

Legal Proceedings

• Hearings with the Montana Public Service Commission (MPSC) and South Dakota Public Utilities Commission (SDPUC) are scheduled in the second quarter of 2026 regarding merger settlement agreements.
• A motion for rehearing filed with the Federal Energy Regulatory Commission (FERC) concerning the Puget Interests is expected to be ruled on in the second quarter of 2026.

Stakeholder Impact

• Shareholders: Merger progress and dividend declaration are positive. GAAP EPS decline may be a concern, but affirmed guidance and adjusted EPS provide some reassurance.
• Customers: South Dakota wildfire legislation offers protection. Large New Load tariff proposal aims to support economic development while protecting existing customers.
• Employees: Merger may lead to integration challenges and potential restructuring, though retention of key personnel is a stated goal.
• Creditors: Decreased liquidity may be a point of attention, though the company has access to credit facilities and plans debt issuances.

Next Steps

• Hold virtual annual meeting of shareholders on April 30, 2026.
• Host investor conference call and webcast on April 30, 2026, to review financial results.
• Complete the issuance and sale of $150.0 million of South Dakota First Mortgage Bonds on June 15, 2026.

• Seek MPSC and SDPUC approval for merger settlement agreements.

Key Dates

Recommendation

The company demonstrates solid operational performance and strategic progress, particularly with the merger nearing completion and regulatory advancements. However, the decrease in GAAP EPS and the inherent risks associated with merger integration and regulatory approvals warrant a cautious 'hold' stance until further clarity emerges.
