Northwest Natural Holding Co 8-K

What Happened

• Northwest Natural Holding Co (through subsidiary Northwest Natural Gas Company) filed an 8‑K disclosing a March 23, 2026 settlement (Stipulation) with WUTC staff and most parties in its Washington multi‑year rate case. The settlement would change the company’s original 2025 filing and provide phased revenue requirement increases for three rate years beginning August 1, 2026. The Stipulation is subject to review and approval by the Washington Utilities and Transportation Commission (WUTC); new rates are expected to take effect August 1, 2026 if approved.

Key Details

• Settlement revenue increases: Year 1 = $20.1 million; Year 2 = $7.7 million; Year 3 = $8.7 million. (Original 2025 request: $25.6M / $8.6M / $8.3M.)
• Washington footprint and impact: ~99,000 customers in WA (~12% of NW Natural’s customers) and about 8% of NW Natural’s revenues are from Washington.
• Regulatory assumptions: capital structure 50% long‑term debt / 50% common equity; allowed return on equity 9.5% each year; overall rates of return ~7.15%–7.22% across the three years. Average rate base: $328.0M (Year 1) → $369.6M (Year 2) → $410.7M (Year 3).
• Other terms: plant placed in service after March 31, 2025 is subject to review/adjustment/refund; the Stipulation does not resolve the line extension allowance policy (ongoing litigation). Includes ~ $3.5M related to an updated depreciation study.

Why It Matters

• If approved, the settlement would raise NW Natural’s Washington revenues modestly over three years, with the largest single‑year increase reduced from the company’s original request (Year 1 reduced by $5.5M).
• Because Washington represents roughly 8% of NW Natural’s revenues, the settlement’s direct impact on NW Holdings’ consolidated results is limited but still material to Washington operations and near‑term cash flow.
• The outcome remains subject to WUTC approval and potential adjustments; investors should watch for the WUTC order and the August 1, 2026 effective date for new rates.
