2025 Highlights

2026 Guidance and Long-term Growth Targets

"Last year was a pivotal year," said Justin B. Palfreyman, President and CEO of NW Natural Holdings. "We delivered record adjusted earnings per share at the top of our guidance range, deployed a record amount of capital to support customers, and reported our strongest organic customer growth in nearly two decades. I'm incredibly proud that NW Natural gas customers' bills are about the same as they were 20 years ago — a testament to disciplined cost management and long-term rate stability. The strategic decisions we've made over the last few years have resulted in three strong, growing businesses with a long runway of opportunity. Projects like our new MX3 storage expansion strengthen regional reliability, energy affordability, and support our long‑term growth outlook. With momentum on our side, we’re executing with discipline and creating value for our customers and shareholders."

FOURTH QUARTER AND ANNUAL RESULTS

NW Natural Holdings' fourth quarter and annual results are summarized below:

KEY EVENTS

Oregon Commission Approves New Rates for NW Natural

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 our 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.

MX3 Storage Expansion Project Announced

NW Natural Gas Company (NW Natural) is advancing a 4–5 Bcf expansion of its Mist gas storage facility to support regional energy needs. Capacity is committed to investment grade regional utilities and midstream providers, who have agreed to 25-year contracts once Notice to Proceed is received. These new storage services will be regulated by FERC and customers have agreed to a fixed 12.5% return on equity, which should provide stable returns, and a capital structure of 50% equity and 50% long-term debt. Capital expenditures for the project are expected to total approximately $300 million. NW Natural expects the MX3 expansion to be in service by the end of 2029¹

2026 GUIDANCE AND LONG-TERM TARGETS

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. Required funds for the capital expenditures are expected to be internally generated or financed with long-term debt or equity, as appropriate.

ANNUAL RESULTS

We primarily operate through three reportable business segments, which are NWN Gas Utility, SiEnergy, and NWN Water. NW Holdings also has investments and business activities, including NW Natural Renewables, not specifically related to the reportable business segments, which are aggregated and reported as other.

NW Natural Holdings' annual results by business segment are summarized in the table below:

net income increased $32.9 million (or $0.71 per share). On an adjusted basis, net income increased $22.8 million (or $0.45 per share), which excludes the effects of the non-cash regulatory disallowance recorded in the fourth quarter of 2024. The increase in net income primarily reflects new rates in Oregon on Nov. 1, 2024 and Oct. 31, 2025, partially offset by higher operations and maintenance and depreciation expenses.NWN Gas Utility

was acquired on Jan. 7, 2025, and Pines was acquired on June 2, 2025. The segment provided net income of $13.7 million (or $0.33 per share) in 2025. Results were primarily driven by customer growth and investments in the system.SiEnergy Gas Utility

net income increased $8.7 million (or $0.21 per share) mainly reflecting an increase in operating revenues primarily due to new rates for its Arizona utilities and water acquisitions. This was partially offset by higher operations and maintenance expenses.NWN Water Utility

net loss from the Company's other business activities increased $20.9 million (or $0.51 per share). On an adjusted basis, the net loss increased $15.9 million ($0.39 per share), which excludes transaction expenses and business development costs. The change in the adjusted net loss was primarily related to higher interest expense due to incremental financings at NW Natural Holdings in December 2024 and March 2025.Other

FOURTH QUARTER RESULTS

NW Natural Holdings' fourth quarter results by business segment are summarized in the table below:

net income increased $7.5 million (or $0.15 per share). Margin increased due to new rates from the Oregon rate case effective Oct. 31, 2025, partially offset by higher depreciation and property taxes from investment in the system. On an adjusted basis, net income decreased $2.6 million (or $0.10 per share), which excludes the non-cash regulatory disallowance in the fourth quarter of 2024.NWN Gas Utility

was acquired on Jan. 7, 2025, and Pines was acquired on June 2, 2025. The segment provided net income of $5.7 million (or $0.13 per share) driven by customer growth and investments in the system.SiEnergy Gas Utility

net income increased $2.4 million (or $0.06 per share) mainly reflecting strong organic customer growth, partially offset by higher operations and maintenance and depreciation expenses.NWN Water Utility

net loss from the Company's other business activities increased $2.8 million (or $0.07 per share). The higher net loss was primarily due to higher interest expense mainly from incremental financings in December 2024 and March 2025, partially offset by higher contributions from NW Natural Renewables from a full quarter of renewable natural gas production in 2025. On an adjusted basis, net loss increased $4.4 million (or $0.11 per share), which excludes the SiEnergy transaction costs in the fourth quarter of 2024.Other

DIVIDEND DECLARED

In January 2026, 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 was paid on Feb. 13, 2026 to shareholders of record on Jan. 30, 2026. The Company’s current indicated annual dividend rate is $1.97 per share. Future dividends are subject to board of director discretion and approval.

The call will also be webcast in a listen-only format for the media and general public and can be accessed atir.nwnaturalholdings.com

Forward-looking statements are based on current expectations and assumptions regarding its business, the economy, geopolitical factors, and other future conditions.

Actual results may differ materially from those contemplated by the forward-looking statements. You are therefore cautioned against relying on any of these forward-looking statements. They are neither statements of historical fact nor guarantees or assurances of future operational, economic or financial performance. Important factors that could cause actual results to differ materially from those in the forward-looking statements are discussed by reference to the factors described in Part I, Item 1A "Risk Factors", and Part II, Item 7 and Item 7A "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Quantitative and Qualitative Disclosure about Market Risk" in the most recent Annual Report on Form 10-K and in Part I, Items 2 and 3 "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Quantitative and Qualitative Disclosures About Market Risk", and Part II, Item 1A, "Risk Factors", in the quarterly reports filed thereafter, which, among others, outline legal, regulatory and legislative risks, financial, macroeconomic and geopolitical risks, growth and strategic risks, operational risks, business continuity and technology risks, environmental risks and risks related to our water and renewables businesses.

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.
