"The Company continues to perform well, and we're executing on our growth and decarbonization opportunities," said David H. Anderson, CEO of NW Natural Holdings. "Our mission is to continue providing utility services and renewable energy to customers safely, reliably, and affordably in a sustainable way to better the lives of the communities we serve."

For the second quarter of 2023, net income was $1.2 million (or $0.03 per share), compared to net income of $1.7 million (or $0.05 per share) for the same period in 2022. Results reflected higher operating costs, partially offset by new rates in Oregon and Washington for our natural gas utility.

Net income increased $15.0 million to $72.9 million (or $2.03 per share) for the first six months of 2023, compared to $58.0 million (or $1.77 per share) for the same period in 2022. Results reflected new rates in Oregon and Washington for our natural gas utility, customer growth and lower pension expense, partially offset by higher operations and maintenance expenses.

NW Natural Water launched its services business in April by acquiring King Water Company in Washington and signing agreements with Hiland Water Corporation in May to acquire its services company and utility connections in Oregon. The two businesses support a combined 15,000 connections. This business provides operations and maintenance services to water and wastewater system owners and works to create value by leveraging shared personnel, technology and expertise to support delivery of clean, reliable water at a reasonable cost. The Hiland Water transaction is expected to close by the end of 2023. Upon closing outstanding transactions, NW Natural Water would serve approximately 170,000 people through more than 68,000 meters and provide operation and maintenance services to an additional 15,000 connections.

In August 2023, EDL announced that the Carbon Limestone RNG facility began operations. This is the first of two facilities NW Natural Renewables is investing in with EDL, a leading global producer of sustainable distributed energy. NW Natural Renewables has contracted to provide approximately $50 million toward the development of the two production facilities that are designed to convert landfill waste gases to RNG and connect that production to the existing regional pipeline networks. The second facility is expected to come online this fall.

NW Natural Renewables and EDL executed agreements designed to obtain a 20-year supply of RNG produced by the facilities for NW Natural Renewables. NW Natural Renewables has separately contracted to sell an equivalent amount of fixed-volume RNG supply to investment grade counterparties under long-term contracts. The revenues associated with these agreements are expected to start when the facilities begin commercial operations.

We primarily operate through our natural gas distribution segment, which is operated through a regulated utility and 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 RNG development and procurement for the utility.

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; NW Natural Water, which holds our water and wastewater utility operations and continues to pursue acquisitions in the water and wastewater sector; and NW Natural Renewables, which is a competitive renewable fuels business.

The following financial comparisons are for the second quarter of 2023 and 2022 with individual year-over-year drivers below presented on an after-tax basis using a statutory tax rate of 26.5% unless otherwise noted.

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

Natural Gas Distribution segment net income decreased $0.4 million (or $0.01 per share) primarily reflecting higher operations expenses, partially offset by new rates in Oregon and Washington that went into effect on Nov. 1, 2022.

Margin increased $11.4 million primarily due to new rates, which contributed $7.6 million; a $2.4 million higher gain from the Oregon gas cost incentive sharing mechanism due to lower than estimated gas costs; and the amortization of deferrals approved in the rate case contributed $1.2 million.

Operations and maintenance expense increased $8.4 million or 24% as a result of higher payroll costs; information technology costs; contractor labor; and the amortization of deferrals approved in the rate case, which is offset by revenues.

Depreciation and general taxes collectively increased by $3.2 million due to additional capital investments in the distribution system including several significant information technology projects that were placed into service in September 2022.

Other income, net reflected a benefit of $3.0 million primarily from lower pension expense, interest income from invested cash, and higher equity Allowance for Funds Used During Construction (AFUDC).

Interest expense increased $3.3 million due to higher debt balances.

Forward-looking statements are based on current expectations and assumptions regarding its business, the economy, geopolitical factors, and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. 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, epidemics and pandemics risks, macroeconomic and geopolitical risks, growth and strategic risks, operational risks, and environmental risks.

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 above.
