As previously disclosed, on August 29, 2025, Northwest Natural Gas Company (NW Natural), a wholly owned subsidiary of Northwest Natural Holding Company (NW Holdings), filed a request for a general rate increase (Rate Case) with the Washington Utilities and Transportation Commission (WUTC) under Washington's multi-year rate plan statute. Also as previously disclosed, on March 23, 2026, NW Natural, Staff of the WUTC, The Energy Project, and the Alliance of Western Energy Consumers, which comprise all but one of the parties to the Rate Case, filed a settlement with the WUTC that addressed all issues but one in the Rate Case (Stipulation).
On July 29, 2026, the WUTC issued an order in the Rate Case (Order). The Order approved the Stipulation, subject to certain adjustments and conditions, and resolved the remaining litigated issue by preserving NW Natural’s line extension allowance in Washington.
The Order provides for a $20.1 million revenue increase in the first year beginning in August 2026 (Year 1), a $7.5 million revenue increase in the second year beginning in August 2027 (Year 2), and a $7.4 million revenue increase in the third year beginning in August 2028 (Year 3). The revenue requirement for Year 1 includes additions to rate base expected to be placed into service by the start of Year 1. Years 2 and 3 include expected additions to rate base during the rate years. Plant placed into service after March 31, 2025 is subject to review, adjustment and refund according to actual costs incurred. The incremental revenue requirement for each year is based upon the following assumptions:
| Year 1 | Year 2 | Year 3 | |||||||||||||||
| Revenue Requirement Increase | $20.1 million | $7.5 million | $7.4 million2 | ||||||||||||||

| Average Rate Base | $328.0 million1 | $368.2 million | $397.8 million | ||||||||||||||
1 Represents an increase of $80.7 million since the last rate case.
2 Includes approximately $3.5 million related to an updated depreciation study.
New rates authorized by the Order are scheduled to take effect on August 1, 2026.
