Signed Agreement to Acquire Another Texas Gas Utility; Reaffirmed 2025 Adjusted EPS Guidance

Northwest Natural Holding Company (NYSE:NWN) (NW Natural Holdings) reported financial results and highlights, including:

Reported earnings per share (EPS) of $2.18 and achieved adjusted EPS¹ of $2.28 for the first quarter of 2025, compared to EPS of $1.69 for the same period in 2024
Closed the acquisition of SiEnergy, a Texas high-growth gas utility, in early January 2025
Signed agreement to purchase Hughes Gas Resources, Inc. (Hughes), adding scale to the SiEnergy gas utility platform in Texas
Added nearly 84,000 gas and water utility connections in the last 12 months for a combined growth rate of 9.6% as of March 31, 2025, mainly driven by the acquisition of SiEnergy
Strong first quarter organic customer growth of 2.2% (annualized) on a consolidated basis with new meter sets on track for the year and growth driven by SiEnergy
Oregon gas customers received bill credits totaling over $15 million in early 2025 related to strong gas supply management from our storage assets and pipeline capacity optimization. Over the last 20 years, we've credited NW Natural customers' bills with cumulative savings of over $280 million, helping keep rates affordable
Invested $102 million in our gas and water systems in the first quarter of 2025 to support growth and greater reliability and resiliency
For the fourth year in a row, honored as one of the World's Most Ethical Companies® by Ethisphere²
Updated 2025 GAAP EPS guidance to $2.65 to $2.85 and reaffirmed adjusted 2025 EPS¹ guidance of $2.75 to $2.95³
Reaffirmed long-term EPS growth rate target of 4% to 6% from our expected 2025 adjusted EPS^1,3

"We are off to a good start in 2025 with solid first quarter financial results," said Justin B. Palfreyman, President and CEO of NW Natural Holdings. "Our gas utilities operated safely and reliably over the winter heating season, serving customers well and highlighting the value of our infrastructure. Our financial results reflect the strength of our collective utilities, including the SiEnergy acquisition that was completed in early January 2025. The SiEnergy integration has gone well, and they have met their growth targets for the first quarter of 2025. I'm excited to announce an additional bolt-on acquisition that further enhances the scale and growth of our Texas utilities. We are well-positioned to deliver on our 2025 guidance and focused on creating long-term shareholder value."

Net income increased $24.1 million to $87.9 million (or $2.18 per share) for the first quarter of 2025, compared to $63.8 million (or $1.69 per share) for the same period in 2024. Adjusted net income was $91.8 million¹ (or $2.28 per share¹) for the first quarter of 2025 excluding transaction costs associated with the SiEnergy acquisition. The increase 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 related to new rates at our largest utility in Arizona and the Puttman acquisition, and a full quarter of revenues from NWN Renewables. These items were partially offset by higher depreciation and interest expense.

SIGNED AGREEMENT TO PURCHASE GROWING GAS UTILITY IN TEXAS

In May 2025, SiEnergy entered into an agreement to acquire Hughes from EPCOR USA Inc. for $60 million, subject to customary purchase price adjustments. We estimate rate base of approximately $46 million at year end 2025. Upon closing the transaction, Hughes will become a wholly owned subsidiary of SiEnergy.

³		Adjusted EPS growth forecasted for period 2025 – 2030 compounded annually; EPS growth rate uses adjusted 2025 EPS 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.

Hughes serves approximately 6,900 residential and commercial customers in the greater Houston metropolitan area. With a similar business model as SiEnergy, Hughes has grown organically by providing infrastructure to residential and commercial developments in high-growth areas.

This acquisition further expands our regulated gas utility business in Texas with a contracted customer backlog of approximately 11,000. The transaction is expected to close in the second quarter of 2025 and be accretive in the first full year of operations. Hughes is regulated by the Railroad Commission of Texas. No approvals are needed to close this transaction.

2025 GUIDANCE AND LONG-TERM TARGETS

NW Natural Holdings updated 2025 GAAP EPS guidance to $2.65 to $2.85 (from the previous range of $2.66 to $2.86) as a result of the expected transaction costs from the Hughes acquisition. NW Natural Holdings reaffirmed adjusted EPS guidance of $2.75 to $2.95 on a non-GAAP¹ basis excluding the $5.8 million pre-tax transaction costs associated with the acquisitions of SiEnergy and Hughes (approximately $4.3 million or $0.10 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.

We expect NW Natural Holdings 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 May 15, 2025 to shareholders of record on April 30, 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.

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 related costs including the effects of SiEnergy transaction costs of $3.9 million after tax recorded in first quarter 2025 and the expected $0.4 million after tax from the acquisition of Hughes anticipated in the second quarter of 2025.
²		Effect on EPS assumes average diluted shares of 41.1 million and an income tax rate of 26.5%.

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.

NWN Gas Utility

NWN Gas Utility is a regulated utility principally engaged in the delivery of natural gas to customers in Oregon and southwest Washington. The segment also includes the portion of the Mist underground storage facility used to serve gas utility customers, the North Mist gas storage expansion, and renewable natural gas development and procurement for the utility.

See "Non-GAAP Financial Measures" for additional information and the table under "First Quarter Results" for a reconciliation to Consolidated NW Natural Holdings EPS. Segment EPS is a non-GAAP financial measure which takes NWN Gas Utility segment net income calculated in accordance with GAAP and divides it by the diluted shares outstanding of NW Natural Holdings.

NWN Gas Utility net income increased $21.5 million (or $0.42 per share) primarily reflecting new rates in Oregon. Margin increased $38.7 million primarily due to a $42.6 million increase from the Oregon rate case partially offset by lower deferral amortizations of $5.0 million.

Operations and maintenance expense increased $2.2 million primarily due to higher payroll and benefit expense. Depreciation and general taxes collectively increased by $4.8 million primarily due to continued investment in our system. Other expense reflected a $1.4 million increase primarily from higher pension expense. Income taxes increased $9.3 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.

See "Non-GAAP Financial Measures" for additional information and the table under "First Quarter Results" for a reconciliation to Consolidated NW Natural Holdings EPS. Segment EPS is a non-GAAP financial measure which takes SiEnergy Gas Utility segment net income calculated in accordance with GAAP and divides it by the diluted shares outstanding of NW Natural Holdings.

SiEnergy was acquired on January 7, 2025 and subsequently provided net income of $5.5 million (or $0.14 per share) in the first quarter of 2025. Margin results met management's expectations and reflected strong customer growth.

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.

	Three Months Ended March 31,

Segment EPS is a non-GAAP financial measure which takes NWN Water Utility segment net income calculated in accordance with GAAP and divides it by the diluted shares outstanding of NW Natural Holdings.

NWN Water net income increased $2.4 million (or $0.06 per share) mainly reflecting a $3.2 million increase in operating revenues primarily due to new rates at its largest utility in Arizona and incremental revenues from the Puttman/Infrastructure Capital Holdings water utilities after the acquisition in September 2024. Operating expenses increased $0.6 million from higher operations and maintenance expenses primarily related to reflecting the Puttman/Infrastructure Capital Holdings activities in results after the acquisition in 2024. 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.

Net income from the Company's other business activities decreased $5.3 million (or $0.13 per share) reflecting $3.9 million of transaction expenses (after-tax) related to acquiring SiEnergy. Adjusted net loss, which excludes SiEnergy transaction expenses, increased $1.4 million (or $0.03 per share) related to higher interest expense at the Holding Company, partially offset by higher revenues from the NWN Renewables business as it completed its first full quarter of operations.

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 believes that these non-GAAP measures provide meaningful information to investors about NW Natural Holdings' performance because they eliminate the impacts of significant discrete items that are unusual or non-recurring and can affect the comparison of period-over-period results. 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.
