NW Natural Holdings to Acquire Rapidly Growing Gas Utility

Acquisition expands NWN’s presence in Texas

PORTLAND, Ore.--(BUSINESS WIRE)-- Northwest Natural Holding Company (NYSE: NWN) (NW Natural Holdings) today announced it entered into an agreement to acquire SiEnergy Operating, LLC (SiEnergy or the Company) from SiEnergy Capital Partners, LLC (an affiliate of Ridgewood Infrastructure) for $273 million in cash and the assumption of $152 million of debt. Upon closing the transaction, which is expected to occur in the first quarter of 2025, SiEnergy will become a wholly owned subsidiary of NW Natural Holdings.

SiEnergy is one of the fastest growing natural gas distribution utilities in the nation. The Company serves approximately 70,000 residential and commercial customers in the greater metropolitan areas of Houston, Dallas, and Austin (known as the Texas Triangle). SiEnergy has grown organically by providing infrastructure to residential and commercial developments in high-growth areas and has a current contracted customer backlog of over 180,000. SiEnergy’s regulated business model generates stable earnings and is well positioned for future investment opportunities as communities and new developments in the Texas Triangle continue to expand.

As of Dec. 31, 2024, SiEnergy is expected to have approximately $247 million in rate base and to have achieved rate base and customer growth of 26% and 22% compounded annually, respectively, over the last five years ending in 2024. NW Natural Holdings expects capital expenditures for the Company to be in the range of $450 million to $650 million over the next five years. We estimate rate base growth of 6% to 8% from 2023 to 2028 for our regulated utilities, an increase over our previous 5% to 7% projection.

“The acquisition of SiEnergy builds on our core strength of operating utilities and delivering essential services to customers,” said David H. Anderson, CEO of NW Natural Holdings. “Texas is one of the fastest growing states in the nation with a constructive regulatory and policy environment. SiEnergy has a substantial number of contracts to add new customers in the coming years. We believe we will be well positioned to capture additional growth as Texas' population expands and new housing developments provide opportunities for new customers.”

“We have a proven track record of acquiring utilities, supporting growth and delivering safe and reliable service to customers. This acquisition directly aligns with our strategic and financial goals,” said Justin B. Palfreyman, president of NW Natural Holdings. “Through this transaction, we expect to meaningfully increase our presence in Texas, creating more opportunities for organic growth, and setting the stage for future growth. We are excited for SiEnergy to join the team and will aim to build on their incredible track record and drive shareholder value.”

The transaction is expected to further support management's long-term EPS growth outlook of 4% to 6%. In addition, NW Natural Holdings reaffirmed its 2024 EPS guidance in the range of $1.94 to $2.14 on a GAAP basis or $2.20 to $2.40 on a non-GAAP Adjusted Basis¹.

NW Natural Holdings expects to finance the cash portion of the acquisition with junior subordinated notes in the first half of 2025. We do not anticipate issuing common equity to directly fund this transaction. NW Natural Holdings has obtained a committed interim term loan from J.P. Morgan Securities LLC to fund the purchase price of $273 million.

The transaction is expected to close in the first quarter of 2025 subject to customary closing conditions including expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. No regulatory approval is needed from the Railroad Commission of Texas to close this transaction.

J.P. Morgan Securities LLC is serving as exclusive financial advisor to NW Natural Holdings with Stoel Rives, LLP serving as legal advisor.

1 See "Non-GAAP Financial Measures" for a definition and further information on Adjusted Basis EPS.

2 Non-GAAP guidance excludes the $13.7 million non-cash, pre-tax regulatory charge (approximately $10.1 million or $0.26 per share after-tax) related to the Oregon general rate case recorded in the fourth quarter of 2024. Impact on EPS assumes average diluted shares of 39.0 million and an income tax rate of 26.5%.

Non-GAAP Financial Measures

Management uses "adjusted net income" and "adjusted basis earnings per share," both 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 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 table above.
