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

•Reported net income of $71.7 million ($2.01 per share) for the first three months of 2023, compared to earnings of $56.2 million ($1.80 per share) for the same period in 2022

•Added nearly 8,100 natural gas meters in the last 12 months for a growth rate of 1.0% as of March 31, 2023

•Completed construction on Dakota City renewable natural gas (RNG) facility, which is designed to provide environmental attributes on behalf of NW Natural customers

•Honored as one of the 2023 World's Most Ethical Companies® by Ethisphere for the second year in a row1

•Reaffirmed 2023 earnings guidance in the range of $2.55 to $2.75 per share and our long-term earnings per share growth rate target of 4% to 6% compounded annually from 2022 through 2027

"We're continuing to work on behalf of our customers to provide safe, reliable utility service and execute on the decarbonization and growth opportunities in front of us," said David H. Anderson, president and CEO of NW Natural Holdings. "I'm pleased with our strong first quarter and the progress we've made securing renewable natural gas. In addition, I'm proud of NW Natural Holdings being named one of the 2023 World's Most Ethical Companies® by Ethisphere for the second year running. This designation reflects our long-standing commitment to leadership in business integrity through best-in-class ethics, compliance and governance practices."

Net income increased $15.5 million to $71.7 million (or $2.01 per share) for the first three months of 2023, compared to $56.2 million (or $1.80 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, offset by higher operations and maintenance expenses.

NW Natural continues to pursue RNG supply on behalf of our customers under the landmark Oregon Senate Bill 98, which supports renewable energy procurement and investment by natural gas utilities. Operations commenced on the first RNG facility under Senate Bill 98 with Tyson Foods and BioCarbN in January 2022. In April 2023, operations at the second RNG facility began. To date, NW Natural has invested approximately $20 million in two RNG facilities on behalf of gas utility customers.

NW Natural Water launched its services business by acquiring King Water Company in Washington and is poised to sign agreements with an additional water services company 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. With this expansion, NW Natural Water has an opportunity to further broaden its scope, expand its footprint, and help smaller systems improve customer service, compliance, and reliability. We believe our first steps in this sector provide a strong platform that can support a larger scale in the coming years.

Upon closing of these agreements, NW Natural Water will serve over 168,000 people through nearly 68,000 meters and provide operation and maintenance services to an additional 15,000 connections.

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.

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 an unregulated RNG business.

The following financial comparisons are for the first three months 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' year-to-date results are summarized by business segment in the table below:

Natural Gas Distribution segment net income increased $16.6 million (or $0.25 per share) reflecting new rates in Oregon and Washington that went into effect on Nov. 1, 2022, partially offset by higher operating expenses. Earnings per share was affected by issuing 4.5 million of common shares over the last twelve months.

Margin increased $29.3 million primarily due to new rates, which contributed $19.4 million; the amortization of deferrals approved in the rate case contributed $3.8 million; and customer growth of 1.0% over the last 12 months contributed $2.0 million.

Operations and maintenance expense increased $8.7 million or 21% as a result of higher payroll costs; the amortization of deferrals approved in the rate case, which is offset by revenues; information technology costs; and contractor labor.

Depreciation and general taxes collectively increased by $3.3 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 $2.6 million primarily from lower pension expense, interest income from invested cash, and higher equity Allowance for Funds Used During Construction (AFUDC).

Interest expense increased $2.8 million due to higher long-term debt balances.

Other net income decreased $1.1 million (or $0.04 per share) reflecting lower net income from NW Natural Holding's other businesses as a result of higher costs including interest expense, partially offset by higher net income from asset management revenues from NW Natural.

During the first three months of 2023, the Company generated $176.9 million in operating cash flows, compared to $141.0 million for the same period in 2022. The Company used $73.0 million in investing activities during the first three months of 2023 primarily for natural gas utility capital expenditures, compared to $69.8 million used in investing activities during the same period in 2022. Net cash provided by financing activities was $11.2 million for the first three months of 2023, compared to $62.8 million used in financing activities during the same period in 2022. As of March 31, 2023, NW Natural Holdings held cash of $140.8 million.

NW Natural Holdings is reaffirming 2023 earnings guidance in the range of $2.55 to $2.75 per share. This guidance assumes continued customer growth, average weather conditions, and no significant changes in prevailing regulatory policies, mechanisms, or outcomes, or significant local, state or federal laws, legislation or regulations. NW Natural Holdings' long-term earnings per share growth rate target is 4% to 6% compounded annually from 2022 through 2027.

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, COVID-19 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.
