KEY EVENTS

Received Order in NW Natural's Oregon General Rate Case
On Oct. 24, 2025, the Public Utility Commission of Oregon (OPUC) issued an order approving the all-party settlements in NW Natural's Oregon general rate case and resolving the remaining outstanding items. The order increased the revenue requirement by $20.7 million, or 2.0%, over current rates including final adjustments for capital projects placed into service and the depreciation study. The order included a capital structure of 50% common equity and 50% long-term debt, return on equity of 9.5%, and overall cost of capital of 7.12%. Rate base is approximately $2.3 billion, or an increase of $180.1 million, since the last rate case. New rates in Oregon were effective beginning Oct. 31, 2025.

Filed Multi-year General Rate Case in Washington for NW Natural
On Aug. 29, 2025, NW Natural filed a request for a general rate increase with the Washington Utilities and Transportation Commission (WUTC). This multi-year rate plan filing seeks increases in annual revenue requirement over three years, consisting of a $25.6 million revenue increase in the first year beginning Aug. 1, 2026 (Year 1), an $8.6 million revenue increase in the second year beginning Aug. 1, 2027 (Year 2), and an $8.3 million revenue increase in the third year beginning Aug. 1, 2028 (Year 3). The request included a capital structure of 51% common equity, 48% long-term debt, and 1% short-term debt. In addition, it included a request for a return on equity of 10.1% in Year 1 and 10.2% in Year 2 and Year 3.

This is NW Natural's first general rate case since 2021 and the filing reflects the effects of inflation, an updated depreciation study, and long-planned investments primarily supporting system safety and reliability. The process is anticipated to take up to 11 months with new rates expected to take effect Aug. 1, 2026.


2025 GUIDANCE AND LONG-TERM TARGETS
NW Natural Holdings expects 2025 results to be above the midpoint of its updated 2025 GAAP EPS guidance of $2.59 to $2.79, which was updated as a result of transaction and business development costs. NW Natural Holdings also expects to be above the midpoint of its reaffirmed adjusted EPS guidance of $2.75 to $2.95 on a non-GAAP1 basis excluding the $9.1 million pre-tax transaction and business development costs, including the acquisitions of SiEnergy and Pines gas utilities (approximately $6.7 million or $0.16 per share after-tax2). This guidance assumes continued customer growth, average weather conditions, and no significant changes in prevailing regulatory policies, mechanisms, or assumed outcomes, or significant local, state or federal laws, legislation or regulations.

NW Natural Holdings reaffirmed its long-term EPS growth rate target of 4% to 6% compounded annually from the midpoint of the adjusted 2025 EPS guidance range3.

NW Natural Holdings expects capital expenditures for 2025 to be in the range of $450 – $500 million. The timing and amount of the capital expenditures and projects for 2025 or additional investments in our infrastructure during or after 2025 could change based on customer growth, significant changes in prevailing regulatory policies or outcomes, or significant local, state or federal laws, legislation or regulations, or cost estimates. Required funds for the investments are expected to be internally generated or financed with long-term debt or equity, as appropriate.

DIVIDEND DECLARED
The board of directors of NW Natural Holdings declared a quarterly dividend of $0.4925 per share on the Company’s common stock. The dividend is payable on Nov. 14, 2025 to shareholders of record on Oct. 31, 2025. The Company's current indicated annual dividend rate is $1.97 per share. Future dividends are subject to board of director discretion and approval.





1 See "Non-GAAP Financial Measures" and "2025 Guidance Reconciliation to GAAP" for a definition and further information on adjusted EPS. Adjusted EPS excludes transaction and business development costs, including the effects of SiEnergy and Pines.
2 Effect on EPS assumes average diluted shares of 40.9 million and an income tax rate of 26.5%.
3 Adjusted EPS growth forecasted for period 2025 – 2030 compounded annually; EPS growth rate uses midpoint of adjusted 2025 EPS guidance range as base year. NW Natural Holdings does not provide a reconciliation of adjusted EPS growth rate target to the most directly comparable GAAP measures due to the inherent difficulty in forecasting and quantifying certain significant items. These items are uncertain, depend on various factors and could have a material impact on GAAP-reported results for the relevant period.

Year-to-Date Results: NWN Water net income increased $6.3 million (or $0.14 per share) mainly reflecting an $11.2 million increase in operating revenues primarily due to new rates for its Arizona utilities and incremental revenues from the ICH water utilities acquisition.

Third Quarter Results: The net loss from the Company's other business activities increased $5.8 million (or $0.14 per share). The increase in the net loss was primarily due to higher interest expense mainly from the issuance of junior subordinated notes in March 2025.

Year-to-Date Results: The net loss from the Company's other business activities increased $18.1 million (or $0.44 per share). On an adjusted basis, the net loss increased $11.4 million ($0.28 per share), which excludes transaction expenses and business development costs. The increase in the adjusted net loss was primarily related to higher interest expense primarily due to incremental financings at NW Natural Holdings in December 2024 and March 2025.

NON-GAAP FINANCIAL MEASURES
Management uses "adjusted net income", "adjusted earnings per share," "adjusted segment net loss," "segment earnings per share” and "adjusted segment earnings per share," each of which are non-GAAP financial measures, when evaluating NW Natural Holdings' overall performance. Management uses non-GAAP measures in making operating decisions because we believe those measures provide meaningful supplemental information regarding our earning potential and performance for management by excluding certain expenses and charges that may not be indicative of our core business operating results and can affect the comparison of period-over-period results. These adjustments may include transaction and business development costs primarily consisting of professional fees including legal, accounting, financial and other professional fees incurred in connection with business combinations and business development activities. In addition to presenting the results of operations and earnings amounts in total, certain financial measures are expressed in cents per share, which are non-GAAP financial measures. All references to EPS are on the basis of diluted shares.

Such non-GAAP financial measures are used to analyze our financial performance because we believe they provide useful information to our investors and creditors in evaluating our financial condition and results of operations. Our non-GAAP financial measures should not be considered a substitute for, or superior to, measures calculated in accordance with U.S. GAAP. Moreover, these non-GAAP financial measures have limitations in that they do not reflect all the items associated with the operations of the business as determined in accordance with GAAP. Other companies may calculate similarly titled non-GAAP financial measures differently than how such measures are calculated in this report, limiting the usefulness of those measures for comparative purposes. A reconciliation of each non-GAAP financial measure to the most directly comparable GAAP financial measure is provided in the tables below.
