Business Overview

  • Core business model: Regulated natural gas distribution primarily in Oregon and southwest Washington through NWN Gas Utility segment
  • New emphasis on SiEnergy (Texas gas distribution and transmission) and NWN Water (regulated/unregulated water services) as distinct reportable segments starting 2025
  • Strategic repositioning with segment restructuring: NGD segment renamed NWN Gas Utility; SiEnergy and NWN Water elevated to core reporting segments
  • Service to ~810,000 gas meters with 2025 storage deliverability of 7.0 million therms/day; 60% gas supply sourced from Canada, 40% from U.S. Rockies
  • Planned 4-5 Bcf expansion at North Mist gas storage facility announced in Feb 2026, permitted Jan 2025, conditional on customer approvals

Risk Factors

  • Operational vulnerability: 4-5 Bcf North Mist gas storage expansion dependent on customer approval, permits, and timely project authorization
  • Market disruption risk: competition from electric heat pumps and alternative technologies could erode NW Natural’s natural gas customer growth
  • Financial risk: counterparty risk exposure to Jonah Energy in gas reserves arrangement, with Jonah lacking credit ratings and potential impact on cost recovery
