Key Financial Metrics (Six Months Ended June 30, 2026)

Material Changes vs. Prior Period

• Revenue Growth: Consolidated operating revenues increased by $3.48 million (0.5%) compared to the six months ended June 30, 2025, driven by new rates in Oregon effective October 31, 2025, and organic customer growth.
• Profitability: Consolidated net income increased by $12.67 million (14.8%) year-over-year. NW Natural net income rose $1.72 million, primarily due to rate increases, partially offset by higher depreciation and interest expenses.
• Segment Performance:
  • SiEnergy: Net income increased $4.63 million, driven by the acquisition of Pines Holdings (June 2025) and organic growth.
  • NWN Water: Net income decreased $0.82 million due to higher operations and maintenance expenses.
  • Other: Net loss improved (decreased) by $7.15 million due to lower business development and transaction expenses.
• Volume Trends: NW Natural total volumes sold decreased by 50.4 million therms year-over-year due to lower residential and commercial usage, despite a 0.3% increase in total meters.

Guidance, Outlook, and Risks

• Capital Expenditure Outlook: NW Holdings expects 2026 capital expenditures to range from $500 million to $550 million. The five-year plan (2026-2030) is projected between $2.6 billion and $2.9 billion.
• Regulatory Developments:
  • Washington Rate Case: New rates became effective August 1, 2026, providing an incremental revenue requirement of $20.1 million in Year 1.
  • Alternative Rate Mechanism (ARM): NW Natural filed a request for an ARM to recover costs for specific capital projects, with new rates anticipated to take effect October 31, 2026.
• Environmental Liabilities: Total estimated environmental liability is $362.3 million. Significant exposure remains at the Portland Harbor site (Gasco Sediments and Uplands), where remediation costs are deferred and recovered through rates subject to prudence reviews.
• Climate Policy Risks: The company faces ongoing regulatory uncertainty regarding the Washington Climate Commitment Act (CCA) and Oregon Climate Protection Program (CPP), which impose GHG emission reduction requirements. The company is currently recovering compliance costs in rates.
• Dividends: The Board declared a quarterly dividend of $0.4925 per share, payable August 14, 2026.

Investor Verification Checklist

• Rate Case Outcomes: Verify the final implementation details and revenue impact of the Washington multi-year rate plan and the pending Oregon Alternative Rate Mechanism (ARM).
• Environmental Cost Recovery: Monitor the status of the Oregon earnings test and prudence reviews for the $362.3 million in deferred environmental remediation costs, particularly regarding the Portland Harbor site.
• Debt Maturities: Review the $125.7 million in debt maturing within the next 12 months and the company's refinancing strategy given current interest rate environments.
• SiEnergy Integration: Assess the ongoing integration and performance of the SiEnergy and Pines Holdings acquisitions, which contributed significantly to YTD growth.
• Regulatory Asset Recoverability: Confirm the continued recoverability of regulatory assets, especially those related to climate compliance (CCA/CPP) and gas storage expansion projects.
