• Realized strong organic customer growth of 1.9% (annualized) on a consolidated basis for the first half 2025
• Updated 2025 GAAP EPS guidance to $2.60 to $2.80 and reaffirmed adjusted 2025 EPS¹ guidance of $2.75 to $2.95²

"Our second quarter results extend our solid financial performance for 2025 and keep us on pace for the year," said Justin B. Palfreyman, President and CEO of NW Natural Holdings. "Our team continues to execute well on all of our strategic objectives, and I am particularly pleased with the strong customer growth we are seeing across our businesses."

For the second quarter of 2025, the Company reported a net loss of $2.5 million (or $0.06 per share), compared to $2.8 million (or $0.07 per share) for the same period in 2024. Adjusted net income increased $3.1 million to $0.3 million¹ (or $0.01 per share¹) for the second quarter of 2025 compared to the same period last year. For the first six months of 2025, net income increased $24.4 million to $85.4 million (or $2.11 per share), compared to $61.0 million (or $1.60 per share) for the same period in 2024. Adjusted net income increased $31.1 million to $92.1 million¹ (or $2.28 per share¹) for the first six months of 2025 compared to the same period last year. Adjusted net income excludes transaction costs associated with the SiEnergy and Pines acquisition, and business development costs in 2025. The increase in net income for the first six months of 2025 compared to the same period last year reflected strong results across all business segments, including new rates for our gas utility in Oregon, contributions from SiEnergy, higher net income from our NWN Water utility primarily due to new rates at our largest utility in Arizona and water acquisitions, and earnings contribution from NWN Renewables. These items were partially offset by higher operations and maintenance costs, depreciation, and interest expense.

KEY EVENTS

Reached Settlements in Oregon General Rate Case for NW Natural

On Dec. 30, 2024, NW Natural filed a request for a general rate increase with the Public Utility Commission of Oregon (OPUC). The filing requested a $59.4 million annual revenue requirement increase (including an approximately $10 million increase from a depreciation study). The request also included an increase in average rate base of $204 million compared to the last rate case to support long-planned investments related to safety and reliability upgrades.

On June 23, 2025, NW Natural and other parties to the rate case filed a settlement with the OPUC, which addresses the revenue requirement components of the rate case. The settlement provides a $21.3 million or 2.5% increase in revenue requirement over current rates (including a $4.8 million increase related to an updated depreciation study). The settlement 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%. We expect rate base of approximately $2.2 billion or an increase of $144 million since the last rate case.

An additional settlement has been filed related to non-revenue requirement items in the rate case. The settlements are subject to review and approval by the OPUC and the completion of capital projects identified as being placed in service prior to the rate effective date. New rates in Oregon are expected to take effect Oct. 31, 2025.

Closed the acquisition of Hughes Gas Resources, Inc. (rebranded as Pines Holdings, Inc. or Pines)

In June 2025, SiEnergy closed the acquisition of Pines from EPCOR USA Inc. for $60.8 million. Pines serves approximately 7,000 connections in 12 communities northeast of Houston and is expected to have a rate base of approximately $47 million at the end of 2025. With a similar business model as SiEnergy, Pines has grown organically by providing infrastructure to residential and commercial developments in high-growth areas. Pines further expands SiEnergy's regulated gas utility business in Texas with a contracted customer backlog of over 12,000 as of June 30, 2025.

2025 GUIDANCE AND LONG-TERM TARGETS

NW Natural Holdings updated 2025 GAAP EPS guidance to $2.60 to $2.80 as a result of the final transaction costs from the Pines acquisition and business development costs. NW Natural Holdings reaffirmed adjusted EPS guidance of $2.75 to $2.95 on a non-GAAP¹ basis excluding the $8.6 million pre-tax transaction costs associated with the acquisitions of SiEnergy and Pines and business development costs (approximately $6.3 million or $0.15 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 expected 2025 adjusted EPS³.

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 $0.49 per share on the Company's common stock. The dividend is payable on Aug. 15, 2025 to shareholders of record on July 31, 2025. The Company's current indicated annual dividend rate is $1.96 per share. Future dividends are subject to board of director discretion and approval.

Second Quarter Results: NWN Gas Utility net income increased $4.5 million (or $0.12 per share) primarily reflecting new rates in Oregon. Margin increased $16.9 million primarily due to an increase from the Oregon rate case effective Nov. 1 2024. Operations and maintenance expense increased $6.3 million due to higher payroll and benefit expense and non-payroll costs including increased contractor expenses. Depreciation and general taxes collectively increased by $4.8 million primarily due to continued investment in our system. Income taxes increased $1.3 million dollars due to higher pre-tax results.

Year-to-Date Results: NWN Gas Utility net income increased $26.0 million (or $0.54 per share) primarily reflecting new rates in Oregon. Margin increased $55.6 million primarily due to an increase from the Oregon rate case. Operations and maintenance expense increased $8.5 million primarily due to higher payroll and benefit expense. Depreciation and general taxes collectively increased by $9.5 million primarily due to continued investment in our system. Other expense reflected a $1.7 million increase primarily from higher pension expense partially offset by higher equity allowance for funds used during construction (AFUDC) and interest income on invested cash. Income taxes increased $10.6 million dollars due to higher pre-tax results.

SiEnergy Gas Utility

SiEnergy Gas Utility (or SiEnergy) is a regulated natural gas distribution utility serving customers in the greater metropolitan areas of Houston, Dallas, and Austin, Texas.

Margin results met management's expectations and reflected strong customer growth during the second quarter and first six months of 2025.

NWN Water Utility

NWN Water Utility (or NWN Water) provides water distribution and wastewater services to communities throughout the Pacific Northwest, Texas, Arizona, and California.

Second Quarter Results: NWN Water net income increased $1.8 million (or $0.04 per share) mainly reflecting a $4.8 million increase in operating revenues primarily due to new rates at its largest utility in Arizona and incremental revenues from the Infrastructure Capital Holdings/Puttman (ICH) water utilities after the acquisition in September 2024. Operating expenses increased $2.3 million from higher operations and maintenance expenses primarily due to the addition of ICH activities in results.

Year-to-Date Results: NWN Water net income increased $4.2 million (or $0.10 per share) mainly reflecting a $8.0 million increase in operating revenues primarily due to new rates for its Arizona utilities and incremental revenues from the ICH water utilities acquisition. Operating expenses increased $2.9 million from higher operations and maintenance expenses and depreciation expense primarily due to the addition of ICH activities in results. Interest expense decreased $0.7 million from lower long-term debt balances as $50.0 million of NWN Water debt matured in March 2024 and was not refinanced at NWN Water.

Other

Other business activities are reported through "Other" results and primarily include Interstate Storage Services and third-party asset management services for the Mist facility in Oregon; NWN Renewables, which is a renewable fuels business; and corporate financing activities, consolidation entries, and other activities.

Second Quarter Results: The net loss from the Company's other business activities increased $7.0 million (or $0.18 per share). On an adjusted basis, the net loss increased $4.2 million (or $0.11 per share), which excludes transaction expenses and business development costs. The increase in the adjusted net loss was primarily due to $9.1 million 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 $12.3 million (or $0.29 per share). On an adjusted basis, the net loss increased $5.6 million ($0.12 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.
