Northwest Natural Holding Co 8-K

What Happened

• Northwest Natural Holding Co (NWN) reported that its utility subsidiary, Northwest Natural Gas Company (NW Natural), received an order from the Washington Utilities and Transportation Commission (WUTC) on July 29, 2026 approving a multi‑year rate plan. The order adopts a previously filed settlement (Stipulation) with certain adjustments and preserves NW Natural’s line extension allowance in Washington. New rates are scheduled to take effect August 1, 2026.

Key Details

• Revenue increases: $20.1 million in Year 1 (beginning Aug 2026), $7.5 million in Year 2 (Aug 2027), and $7.4 million in Year 3 (Aug 2028) — total ≈ $35.0 million incremental revenue across the three years.
• Rate base and returns: Average rate base of $328.0M (Yr1), $368.2M (Yr2), $397.8M (Yr3); return on equity set at 9.5% for each year; overall rates of return of 7.15% (Yr1), 7.18% (Yr2), 7.22% (Yr3).
• Capital structure: authorized at 50.0% long‑term debt / 50.0% common equity. Year‑1 rate base represents an $80.7M increase since the prior rate case; about $3.5M of the revenue change reflects an updated depreciation study.
• Other conditions: Plant placed into service after March 31, 2025 is subject to review, adjustment and refund based on actual costs incurred.

Why It Matters

• For investors, the WUTC order formalizes higher authorized Washington utility revenues beginning August 1, 2026, which affects NW Natural’s regulated revenue and rate base in Washington. The approved return and capital structure parameters are key inputs for future regulated earnings.
• The decision reduces regulatory uncertainty in Washington by resolving the rate case (including the remaining contested issue) and sets the framework for recovery of specified plant and depreciation updates; customers may see rate impacts consistent with the approved revenue increases.
