ITEM 1. BUSINESS
OVERVIEW
NW Holdings is a holding company headquartered in Portland, Oregon and owns NW Natural, NW Natural Water Company, LLC (NWN Water), NW Natural Renewables Holdings, LLC, a non-regulated subsidiary established to pursue non-regulated renewable natural gas activities, and other businesses and activities. NW Natural is NW Holdings’ largest subsidiary.
NW Natural distributes natural gas to residential, commercial, and industrial customers in Oregon and southwest Washington. NW Natural and its predecessors have supplied gas service to the public since 1859, was incorporated in Oregon in 1910, and began doing business as NW Natural in 1997. NW Natural's natural gas distribution activities are reported in the natural gas distribution (NGD) segment. All other business activities, including certain gas storage activities, water and wastewater businesses, non-regulated renewable natural gas activities and other investments and activities are aggregated and reported as "other" at their respective registrant.
Our mission is to provide safe, reliable and affordable utility services and renewable energy in a sustainable way to better the lives of the communities we serve. We support our mission by following our core values of service ethic, integrity, safety, caring, and environmental stewardship.
NATURAL GAS DISTRIBUTION (NGD) SEGMENT
Both NW Holdings and NW Natural have one reportable segment, the NGD segment, which is operated by NW Natural. NGD provides natural gas service through approximately 806,000 meters in Oregon and southwest Washington. Approximately 88% of customers are located in Oregon and 12% are located in southwest Washington.
NW Natural has been allocated an exclusive service territory by the Oregon Public Utility Commission (OPUC) and Washington Utilities and Transportation Commission (WUTC), which includes the major population centers in western Oregon, including the Portland metropolitan area, most of the Willamette Valley, the Coastal area from Astoria to Coos Bay, and portions of Washington along the Columbia River. Major businesses located in NW Natural's service territory include retail, manufacturing, and high-technology industries.
Customers
The NGD business serves residential, commercial, and industrial customers with no individual customer accounting for more than 10% of NW Natural's or NW Holdings' revenues. On an annual basis, residential and commercial customers typically account for approximately 60% of NGD volumes delivered and approximately 90% of NGD margin. Industrial customers largely account for the remaining volumes and margin.
The following table presents summary meter information for the NGD segment as of December 31, 2024:
| | | | | | | | | | | | | | | | | | | | |
| | Number of Meters | | % of Volumes | | % of Margin |
| Residential | | 735,117 | | | 38 | % | | 65 | % |
| Commercial | | 69,362 | | | 23 | % | | 25 | % |
| Industrial | | 1,050 | | | 39 | % | | 6 | % |
Other(1) | | N/A | | N/A | | 4 | % |
| Total | | 805,529 | | | 100 | % | | 100 | % |
(1) NGD margin is also affected by other items, including miscellaneous revenues, gains or losses from NW Natural's gas cost incentive sharing mechanism, other margin adjustments, and other regulated services.
Generally, residential and commercial customers purchase both their natural gas commodity (gas sales) and natural gas delivery services from the NGD business. Industrial and some large commercial customers also purchase the gas commodity either from NW Natural or directly from a third-party gas marketer or supplier. Gas commodity cost is primarily a pass-through cost to customers; therefore, profit margins are not significantly affected by an industrial customer's decision to purchase gas from NW Natural or from third parties. Industrial and large commercial customers may also select between firm and interruptible service levels, with firm services generally providing higher profit margins compared to interruptible services.
To help manage gas supplies, tariffs are designed to provide some certainty regarding industrial and commercial customers' volumes by requiring an annual service election, special rates or possible restrictions for changes between elections.
We estimate natural gas was in approximately 63% of single-family residential homes in NW Natural's service territory in 2024. Customer growth in our region comes mainly from the following sources: single-family housing, both new construction and conversions; multifamily housing new construction; and commercial buildings, both new construction and conversions. Single-family new construction has consistently been our largest source of growth. Continued customer growth is closely tied to consumer preference for natural gas, the comparative price of natural gas to electricity and fuel oil, regulations and building codes permitting the use of natural gas in new construction and conversions, and the economic health of our service territory.
Competitive Conditions
In its service areas, the NGD business has no direct competition from other natural gas distributors. However, it competes with other forms of energy in each customer class. This competition among energy suppliers is based on price, efficiency, reliability, performance, preference, perceptions, market conditions, building codes, technology, federal, state, and local energy policy, and environmental impacts.
For residential and small to mid-size commercial customers, the NGD business competes primarily with providers of electricity, fuel oil, and propane.
In the industrial and large commercial markets, the NGD business competes with all forms of energy, including competition from wholesale natural gas marketers. In addition, large industrial customers could bypass NW Natural's natural gas distribution system by installing their own direct pipeline connection to the interstate pipeline system. NW Natural has designed custom transportation service agreements with several large industrial customers to provide transportation service rates that are competitive with the customer’s costs of installing their own pipeline.
Seasonality of Business
The NGD business is seasonal in nature due to higher gas usage by residential and commercial customers during the cold winter heating months. Other categories of customers experience similar seasonality in their usage but to a lesser extent.
Regulation and Rates
The NGD business is subject to regulation by the OPUC and WUTC. These regulatory agencies authorize rates and allow recovery mechanisms to provide the opportunity to recover prudently incurred capital and operating costs from customers, while also earning a reasonable return on investment for investors. In addition, the OPUC and WUTC also regulate the system of accounts and issuance of securities by NW Natural.
NW Natural files general rate cases and rate tariff requests periodically with the OPUC and WUTC to establish approved rates, an authorized return on equity (ROE), an overall rate of return (ROR) on rate base, an authorized capital structure, and other revenue/cost deferral and recovery mechanisms.
NW Natural is also regulated by the Federal Energy Regulatory Commission (FERC). Under NW Natural's Mist interstate storage certificate with FERC, NW Natural is required to file either a petition for rate approval or a cost and revenue study every five years to change or justify maintaining the existing rates for the interstate storage service.
For further discussion on our most recent general rate cases, see Part II, Item 7, "Results of Operations—Regulatory Matters—Regulation and Rates."
Gas Supply
NW Natural strives to secure sufficient, reliable supplies of natural gas to meet the needs of customers at the lowest reasonable cost, while maintaining price stability, managing gas purchase costs prudently and supporting our core value of environmental stewardship. This is accomplished through a comprehensive strategy focused on the following items:
•Reliability - ensuring gas resource portfolios are sufficient to satisfy customer requirements under extreme cold weather conditions;
•Diverse Supply - providing diversity of supply sources;
•Diverse Contracts - maintaining a variety of contract durations, types, and counterparties;
•Cost Management and Recovery - employing prudent gas cost management strategies; and
•Environmental Stewardship - striving to reduce the carbon content and environmental impacts of the energy we deliver.
Reliability
To support system reliability, the NGD business has developed a risk-based methodology in which it uses a planning standard to serve the highest firm sales demand day in any year with 99% certainty.
The projected maximum design day firm NGD customer sales is approximately 10 million therms. Of this total, the NGD business is currently capable of meeting approximately 55% of the requirements with gas from storage located within or adjacent to its service territory, while the remaining supply requirements would come from gas purchases under firm gas purchase contracts and recall agreements.
NW Natural segments transportation capacity, which is a natural gas transportation mechanism under which a shipper can leverage its firm pipeline transportation capacity by separating it into multiple segments with alternate delivery routes. The reliability of service on these alternate routes will vary depending on the constraints of the pipeline system. For those segments with acceptable reliability, segmentation provides a shipper with increased flexibility and potential cost savings compared to traditional pipeline service. The NGD business relies on segmentation of firm pipeline transportation capacity that flows from Stanfield, Oregon to various points south of Molalla, Oregon.
We believe gas supplies would be sufficient to meet existing NGD firm customer demand in the event of maximum design day weather conditions.
The following table shows the sources of supply projected to be used to satisfy the design day sales for the 2024-25 winter heating season:
| | | | | | | | | | | | | | |
| Therms in millions | | Therms | | Percent |
| Sources of NGD supply: | | | | |
| Firm supply purchases | | 3.4 | | | 34 | % |

The OPUC and WUTC have Integrated Resource Planning (IRP) processes in which utilities define different future scenarios and corresponding resource and compliance strategies in an effort to evaluate supply and demand resource and compliance requirements, consider uncertainties in the planning process and the need for flexibility to respond to changes, and establish a plan for providing reliable service while meeting carbon compliance obligations within frameworks that emphasize least cost and risk.
NW Natural generally files a full IRP biennially for Oregon and Washington with the OPUC and the WUTC, respectively, and files updates in Oregon between filings. The OPUC acknowledges NW Natural's action plan, whereas the WUTC provides notice that the IRP has met the requirements of the Washington Administrative Code. OPUC acknowledgment of the IRP does not constitute ratemaking approval of any specific resource acquisition strategy or expenditure. For additional information see Part II, Item 7, "Results of Operations—Regulatory Matters."
Diversity of Supply Sources
NW Natural purchases gas supplies primarily from the Alberta and British Columbia provinces of Canada and multiple receipt points in the U.S. Rocky Mountains to protect against regional supply disruptions and to take advantage of price differentials. For 2024, 60% of gas supply came from Canada, with the balance primarily coming from the U.S. Rocky Mountain region. We believe gas supplies available in the western United States and Canada are adequate to serve NGD customer requirements for
the foreseeable future. NW Natural continues to evaluate the long-term supply mix based on projections of gas production and pricing in the U.S. Rocky Mountain region as well as other regions in North America.
NW Natural supplements firm gas supply purchases with gas withdrawals from gas storage facilities, including underground reservoirs and LNG storage facilities. Storage facilities are generally injected with natural gas during the off-peak months in the spring and summer, and the gas is withdrawn for use during peak demand months in the winter.
The following table presents the storage facilities available for NGD business supply:
| | | | | | | | | | | | | | |
| | Maximum Daily Deliverability (therms in millions) | | Designed Storage
Capacity (Bcf) |
| Gas Storage Facilities | | | | |
| Owned Facility | | | | |
Mist, Oregon (Mist Facility)(1) | | 3.3 | | | 12.8 | |
Mist, Oregon (North Mist Facility)(2) | | 1.3 | | | 4.1 | |
| Contracted Facility | | | | |
Jackson Prairie, Washington(3) | | 0.5 | | | 1.1 | |
| LNG Facilities | | | | |
| Owned Facilities | | | | |
| Newport, Oregon | | 0.8 | | | 1.0 | |
| Portland, Oregon | | 1.0 | | | 0.6 | |
| Total | | 6.9 | | | 19.6 | |
(1) The Mist gas storage facility has a total maximum daily deliverability of 5.3 million therms and a total designed storage capacity of about 17.5 Bcf, of which 3.3 million therms of daily deliverability and 12.8 Bcf of storage capacity are reserved for NGD business customers.
(2) The North Mist facility is contracted to exclusively serve Portland General Electric, a local electric utility, and may not be used to serve other NGD customers. See "North Mist Gas Storage Facility" below for more information.
(3) The storage facility is located near Chehalis, Washington and is contracted from Northwest Pipeline, a subsidiary of The Williams Companies.
The Mist facility serves NGD segment customers and is also used for non-NGD purposes, primarily for contracts with gas storage customers, including utilities, third-party marketers, and electric generators. Under regulatory agreements with the OPUC and WUTC, gas storage at Mist can be developed in advance of NGD customer needs but is subject to recall when needed to serve such customers as their demand increases. When storage capacity is recalled for NGD purposes it becomes part of the NGD segment. As of May 1, 2024, 0.2 million therms per day of deliverability and 1.15 Bcf of associated non-utility Mist gas storage capacity was recalled to serve core customers. Customer rate increases related to this recall began on November 1, 2024. The North Mist facility is contracted for the exclusive use of Portland General Electric, a local electric utility, and may not be used to serve other NGD customers. See "North Mist Gas Storage Facility" below.
Diverse Contract Durations and Types
NW Natural has a diverse portfolio of short-, medium-, and long-term firm gas supply contracts and a variety of contract types including firm and interruptible supplies as well as supplemental supplies from gas storage facilities.
The majority of our gas supply contracts include year-round, winter-only, summer-only, and monthly baseload supplies, and daily spot purchases. We also maintain options to call on additional daily supplies during the winter heating season.
During 2024, a total of 822 million therms were purchased under contracts with durations as follows:
| | | | | |
| Contract Duration (primary term) | Percent of Purchases |
| Long-term (one year or longer) | 31 | % |
| Short-term (more than one month, less than one year) | 45 | |
| Spot (one month or less) | 24 | |
| Total | 100 | % |
During 2024, there was one supplier that provided 10% or more of the NGD business gas supply requirements. No other individual supplier provided 10% or more of the NGD business gas supply requirements.
Gas Cost Management
The cost of gas sold to NGD customers primarily consists of the following items, which are included in annual Purchased Gas Adjustment (PGA) rates: gas purchases from suppliers; charges from pipeline companies to transport gas to our distribution
system; gas storage costs; gas reserves costs; gas commodity derivative contracts; and renewable natural gas and its attributes, including renewable thermal certificates. Costs to comply with Washington's Climate Commitment Act (CCA) are included in the cost of gas for Washington customers. We expect that costs to comply with Oregon's Climate Protection Program (CPP) and any similar program that may be enacted in our service territory will also be included in the cost of gas.
The NGD business employs a number of strategies to mitigate the cost of gas sold to customers. The primary strategies for managing gas commodity price risk include:
•negotiating fixed prices directly with gas suppliers;
•negotiating financial derivative contracts that: (1) effectively convert floating index prices in physical gas supply contracts to fixed prices (referred to as commodity price swaps); or (2) effectively set a ceiling or floor price, or both, on floating index priced physical supply contracts (referred to as commodity price options such as calls, puts, and collars); and
•buying physical gas supplies at a set price and injecting the gas into storage for price stability and to minimize pipeline capacity demand costs.
NW Natural also contracts with an independent energy marketing company to capture opportunities regarding storage and pipeline capacity when those assets are not serving the needs of NGD business customers. Asset management activities provide opportunities for cost of gas savings for customers and incremental revenues for NW Natural through regulatory incentive-sharing mechanisms. These activities, net of the amount shared, are included in other for segment reporting purposes.
Gas Cost Recovery
Mechanisms for gas cost recovery are designed to be fair and reasonable, with an appropriate balance between the interests of customers and NW Natural. In general, natural gas distribution rates are designed to recover the costs of, but not to earn a return on, the gas commodity sold. Risks associated with gas cost recovery are minimized by resetting customer rates annually through the PGA and aligning customer and shareholder interests through the use of sharing, weather normalization, and conservation mechanisms in Oregon. See Part II, Item 7, "Results of Operations—Regulatory Matters" and "Results of Operations—Business Segment—Natural Gas Distribution Operations—Cost of Gas".
Environmental Stewardship
Part of our gas supply strategy is working to reduce the carbon content and the environmental impacts of the energy we deliver. To that end, NW Natural developed and implemented an emissions screening tool that uses Environmental Protection Agency (EPA) data to calculate the relative emissions intensity of gas producer operations and prioritize purchases from lower emitting producers. In 2019, we began using this emissions intensity screening tool alongside other purchasing criteria such as price, credit worthiness and geographic diversity. We view this as a cost-neutral way to reduce carbon emissions associated with our natural gas supply.
NW Natural is focused on taking steps to lower its emissions on behalf of customers by purchasing environmental attributes that are generated by the production of renewable natural gas (RNG). Under Oregon Senate Bill 98, NW Natural can purchase RNG or invest in RNG facilities, which generate these environmental attributes known as Renewable Thermal Certificates (RTCs). In 2019, the Washington State legislature also passed a bill supporting RNG procurement, House Bill 1257. The RTCs work like renewable energy certificates, or RECs, used in electricity markets. RTCs are verified and certified by the Midwest Renewable Energy Tracking System (M-RETS). The M-RETS Renewable Thermal Tracking System issues one RTC for every dekatherm of RNG injected into the gas system. NW Natural enters into contracts for the purchase of RNG and RTCs either through periodic request for proposals or through formal offerings or informal requests. See Part II, Item 7, "Results of Operations—Regulatory Matters".
In addition to purchases of RNG, NW Natural has piloted a hydrogen blend in pipelines serving its Sherwood Operations and Training Center. NW Natural has successfully tested a blend of up to 20% hydrogen. The tests met the safety protocols established by PHMSA Part 192. Additionally, NW Natural is focused on developing several hydrogen pilots for industrial and commercial customers to support their decarbonization goals.
NW Natural is subject to the requirements of the Washington CCA cap-and-invest program, and will be subject to Oregon's CPP. NW Natural has modeled pathways to compliance with the CCA and CPP in its most recent IRP. While costs associated with each possible compliance pathway differ, we intend to pursue recovery of the costs associated with these programs in rates.
Transportation of Gas Supplies
NW Natural's gas distribution system is reliant on a single, bi-directional interstate transmission pipeline to bring gas supplies into the natural gas distribution system. Although dependent on a single pipeline, the pipeline’s gas flows into the Portland metropolitan market from two directions: (1) the north, which brings supplies from the British Columbia and Alberta supply basins; and (2) the east, which brings supplies from Alberta as well as the U.S. Rocky Mountain supply basins.
NW Natural incurs monthly demand charges related to firm pipeline transportation contracts. These contracts have expiration dates ranging from 2025 to 2061. The largest pipeline agreements are with Northwest Pipeline. NW Natural actively works with Northwest Pipeline and others to renew contracts in advance of expiration to ensure gas transportation capacity is sufficient to meet customer needs.
Rates for interstate pipeline transportation services are established by FERC within the U.S. and by Canadian authorities for services on Canadian pipelines.
Gas Distribution
Safety and the protection of employees, customers, and our communities are, and will remain, top priorities. NW Natural constructs, operates, and maintains its pipeline distribution system and storage operations with the goal of ensuring natural gas is delivered and stored safely, reliably, and efficiently.
NW Natural has one of the most modern distribution systems in the country with no identified cast iron pipe or bare steel main. Since the 1980s, NW Natural has taken a proactive approach to replacement programs and partnered with the OPUC and WUTC on progressive regulation to further safety and reliability efforts for the distribution system. In the past, NW Natural had a cost recovery program in Oregon that encompassed programs for cast iron replacement, bare steel replacement, transmission integrity management, and distribution integrity management programs as appropriate.
Natural gas distribution businesses are likely to be subject to greater federal and state regulation in the future. Additional operating and safety regulations from the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) are currently under development. In January 2025, PHMSA released the final rulemaking: Gas Pipeline Leak Detection and Repair. The rulemaking includes congressional mandates from the PIPES (Protecting our Infrastructure of Pipelines and Enhancing Safety) Act of 2020 to reduce methane emissions from new and existing gas transmission, distribution, gathering, underground storage, and LNG facilities. The unpublished rulemaking was placed on a regulatory freeze by the new presidential administration and is expected to undergo additional review and amendment. In September 2023, PHMSA issued a notice of proposed rulemaking: Safety of Gas Distribution Pipelines and Other Pipeline Safety Initiatives. The proposed rulemaking requires operators to update distribution integrity management programs, emergency response plans, operations and maintenance manuals, and other safety practices. NW Natural does not foresee a significant impact of these rulemakings on our business given the modern materials used in our system.
North Mist Gas Storage Facility
The North Mist gas storage facility began operations in 2019. The North Mist facility provides long-term, no-notice underground gas storage service and is dedicated solely to Portland General Electric (PGE) under a 30-year contract with options to extend up to an additional 50 years upon mutual agreement of the parties. PGE uses the facility to fuel its gas-fired electric power generation facilities.
North Mist includes a reservoir providing 4.1 Bcf of available storage, a compressor station with a contractual capacity of 120,000 dekatherms of gas deliverability per day, no-notice service that can be drawn on rapidly, and a 13-mile pipeline to connect to PGE's Port Westward gas plants in Clatskanie, Oregon.
The facility is included in rate base under an established tariff schedule with revenues recognized consistent with the schedule. Billing rates are updated annually to the forecasted depreciable asset level and forecasted operating expenses.
There are additional expansion opportunities in the Mist storage field. Any expansion would be based on market demand, cost effectiveness, available financing, receipt of future permits, and other rights.
OTHER
Certain businesses and activities of NW Holdings and NW Natural are aggregated and reported as other for segment reporting purposes.
NW Natural
The following businesses and activities are aggregated and reported as other under NW Natural, a wholly-owned subsidiary of NW Holdings:
•4.7 Bcf of the Mist gas storage facility contracted to other utilities, third-party marketers, and electric generators;
•natural gas asset management activities; and
•appliance retail center operations.
Mist Gas Storage
The Mist gas storage facility began operations in 1989. It is a 17.5 Bcf facility with 12.8 Bcf used to provide gas storage for the NGD business. The remaining 4.7 Bcf of the facility is contracted with other utilities, third-party marketers, and electric generators with these results reported in other.
The overall facility consists of seven depleted natural gas reservoirs, 21 injection and withdrawal wells, a compressor station, dehydration and control equipment, gathering lines, and other related facilities. The capacity at Mist provides multi-cycle gas storage services to customers in the interstate and intrastate markets. The interstate storage services are offered under a limited jurisdiction blanket certificate issued by FERC. Under NW Natural's interstate storage certificate with FERC, NW Natural is required to file either a petition for rate approval or a cost and revenue study every five years to change or justify maintaining the
existing rates for the interstate storage service. Intrastate firm storage services in Oregon are offered under an OPUC-approved rate schedule as an optional service to certain eligible customers. Gas storage revenues from the 4.7 Bcf are derived primarily from firm service customers who provide energy-related services, including natural gas distribution, electric generation, and energy marketing. The Mist facility benefits from limited competition as there are few storage facilities in the Pacific Northwest region. Therefore, NW Natural has the ability to acquire high-value, multi-year contracts.
Asset Management Activities
NW Natural contracts with an independent energy marketing company to provide asset management services, primarily through the use of natural gas commodity exchange agreements and natural gas pipeline capacity release transactions. The results of these activities are included in other, except for the asset management revenues allocated to NGD business customers pursuant to regulatory agreements, which are reported in the NGD segment.
NW Holdings
These include the following businesses and activities aggregated under NW Holdings:
•NW Natural Water Company, LLC (NWN Water) and its water and wastewater utility operations and water services business;
•NWN Water's equity investment in Avion Water Company, Inc.;
•NW Natural Renewables Holdings, LLC and its non-regulated renewable natural gas activities;
•a minority interest in the Kelso-Beaver Pipeline held by our wholly-owned subsidiary NNG Financial Corporation (NNG Financial); and
•holding company and corporate activities, including business development activities, as well as adjustments made in consolidation.
NW Natural Water
NWN Water currently serves an estimated 190,000 people through approximately 76,000 water and wastewater connections across six states. NWN Water continues to grow though customer additions within or near its service territories, and continues to pursue acquisitions. See further discussion about the status of water general rate cases in Part II, Item 7, "Results of Operations—Regulatory Matters—Water and Wastewater Utilities."
The water and wastewater utilities primarily serve residential and commercial customers. Water distribution operations are seasonal in nature with peak demand generally during warmer summer months, while wastewater is less seasonally affected. Entities generally operate in exclusive service territories with no direct competitors. Water distribution customer rates are regulated by state utility commissions while the wastewater businesses we own consist of some state regulated systems and some systems that are not rate regulated by utility commissions.
NWN Water launched its services business in April 2023. 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. Today, NWN Water provides operations and maintenance services to approximately 25,000 connections.
NW Natural Renewables
NW Natural Renewables is an unregulated subsidiary of NW Natural Holdings established to pursue unregulated RNG activities. In September 2021, a subsidiary of NW Natural Renewables, Ohio Renewables, and a subsidiary of EDL, a global producer of sustainable distributed energy, executed agreements to secure RNG supply from two production facilities that are designed to convert landfill waste gases to RNG (EDL Facilities). The first facility was completed and commenced delivery of RNG to Ohio Renewables in September 2024. Upon reaching this milestone, Ohio Renewables paid $26.0 million to the EDL subsidiary. The second facility was completed and commenced delivery of RNG to Ohio Renewables in December 2024 at which time Ohio Renewables made an additional payment of $25.4 million to the EDL subsidiary.
Alongside these development agreements, Ohio Renewables and the subsidiary of EDL executed agreements for Ohio Renewables to purchase up to an annual specified amount of RNG produced by the EDL Facilities over a 20-year period at a contractually specified price. Ohio Renewables has contracted to sell the supply obtained from EDL at fixed-prices to investment grade counterparties.
Ohio Renewables has contracted to sell RNG produced by the EDL Facilities up to certain specified volumes in each of calendar years 2024 through 2026 to an investment-grade counterparty. We currently estimate RNG volumes to be sold pursuant to this agreement to be approximately 2,430,000 MMbtu over the life of the agreement, provided that such amounts of RNG are produced by the EDL Facilities during that period.
Ohio Renewables additionally has contracted to sell a fixed-volume of RNG under a long-term agreement with an investment-grade utility beginning in 2025 and extending through 2042. Amounts to be delivered under this agreement are estimated to be 112,500 MMbtu in 2025, 375,000 MMbtu in 2026, 1,950,000 MMbtu annually in 2027 through 2034, and 2,775,000 MMbtu annually in years 2035 through 2042. Under the current contract, if less than 75% of the contracted volumes of RNG are not delivered on an annual basis, Ohio Renewables is obligated to pay the per MMbtu price for volumes between the amount delivered and 75% of the contracted volumes on an annual basis.
ENVIRONMENTAL MATTERS
Properties and Facilities
NW Natural owns, or previously owned, properties and facilities that are currently being investigated that may require environmental remediation and are subject to federal, state, and local laws and regulations related to environmental matters. These laws and regulations may require expenditures over a long time frame to address certain environmental impacts. Estimates of liabilities for environmental costs are difficult to determine with precision because of the various factors that can affect their ultimate disposition. These factors include, but are not limited to, the following:
•the complexity of the site;
•changes in environmental laws and regulations at the federal, state, and local levels;
•the number of regulatory agencies or other parties involved;
•new technology that renders previous technology obsolete, or experience with existing technology that proves ineffective;
•the level of remediation required;
•variations between the estimated and actual period of time that must be dedicated to respond to an environmentally-contaminated site; and
•the application of environmental laws that impose joint and several liabilities on all potentially responsible parties.
NW Natural has received recovery of a portion of such environmental costs through insurance proceeds, seeks the remainder of such costs through customer rates, and believes recovery of these costs is probable. In both Oregon and Washington, NW Natural has mechanisms to recover expenses. Oregon recoveries are subject to an earnings test. See Part II, Item 7, "Results of Operations—Regulatory Matters—Rate Mechanisms—Environmental Cost Deferral and Recovery", and Note 2 and Note 17 to the Consolidated Financial Statements in Item 8 of this report for more information.
Greenhouse Gas Matters
For information concerning greenhouse gas matters, see Part II, Item 7, “Results of Operations—Environmental Regulation and Legislation Matters.”
HUMAN CAPITAL
Our core values of integrity, safety, caring, service ethic, and environmental stewardship guide how we engage with customers, stakeholders, shareholders, and communities. We actively work to foster these values in our employee culture and to nurture an inclusive and equitable environment that provides opportunities, prioritizes health and safety, encourages respect and trust, and supports growth and learning. We aim to recruit and retain employees who share our core values and reflect our communities.
Employees
At December 31, 2024, our workforce consisted of the following:
| | | | | |
| NW Natural: | |
Unionized employees(1) | 626 | |
| Non-unionized employees | 649 | |
| Total NW Natural | 1,275 | |
| |
| Other Entities: | |
| Water and wastewater company employees | 172 | |

| Total other entities | 177 | |
| |
| Total Employees | 1,452 | |
(1) Members of the Office and Professional Employees International Union (OPEIU) Local No. 11, AFL-CIO.
NW Natural's labor agreement with members of OPEIU covers wages, benefits, and working conditions. In May 2024, NW Natural's unionized employees ratified a collective bargaining agreement that is in effect June 1, 2024 through May 31, 2028, and is effective thereafter from year to year unless either party serves notice of its intent to negotiate modifications to the collective bargaining agreement. The terms of the collective bargaining agreement include the following items: a 6% wage increase effective June 1, 2024 and scheduled wage increases effective December 1 in the first year and each subsequent year of 4%; a 401(k) contribution of 4% for employees hired after our pension plan was closed on December 31, 2009; and a 401(k) match of 50% of the first 8% of savings. During calendar year 2024, NW Natural did not incur any work stoppages (strikes or lockouts), and therefore, experienced zero idle days for the year.
Certain subsidiaries may receive services from employees of other subsidiaries. Those services are generally charged to the entity receiving those services. When such services involve regulated entities, those entities receiving services are generally
charged rates pursuant to shared services agreements that are filed with the applicable state regulatory commission, as applicable.
Safety
Safety is one of our greatest responsibilities to employees. In managing the business, we strive to foster a safety culture focused on prevention, open communication, collaboration, and a strong service and safety ethic. We believe employee safety is critical to our success. A portion of executives’ compensation is tied to achieving our identified safety metrics, and our Board of Directors regularly reviews company safety metrics and receives reports on matters of health and safety. NW Natural’s health and safety policies and procedures are designed to comply with all applicable regulations, but we also work to go beyond compliance by striving to incorporate information we learn from benchmarking, peer reviews, and industry best practices.
As part of our commitment to employee health and safety, we maintain regular training programs, emergency preparedness procedures, and training and procedures to identify hazards and handle high-risk emergency situations. Employees complete classroom instruction and hands-on, scenario-based training at our training town facility in Oregon that allows employees to experience realistic situations in a controlled environment. We also host natural gas safety training events for first responders, which are designed to prepare those first responders and NW Natural field employees to deliver an integrated, seamless response in the event of an emergency that involves or affects the natural gas system. We also have a learning management system that provides virtual training options and more efficiency and flexibility in how we train.
Employee Benefits and Support
To attract employees and meet the needs of our workforce, NW Natural strives to offer competitive compensation and benefits packages to employees. The benefits package options vary depending on type of employee and date of hire. NW Natural continuously looks for ways to support employees’ work-life balance and well-being and this is reflected in physical, mental and financial wellness programs to meet the needs of our employees and help them care for their families. Benefits available to employees during 2024 included, among others: healthcare and other insurance coverages, wellness resources, retirement and savings plans, paid time off programs, and flexible and hybrid work schedules, where possible, employee resource groups, and culture and community-focused resources and opportunities, and employee recognition programs and discounts.
Talent Attraction and Development
In order to implement our business strategy and serve our customers, we depend upon our continuing ability to attract and retain talented professionals and a technically skilled workforce, and being able to transfer the knowledge and expertise of our workforce to new and increasingly diverse employees as our older workforce retires. A significant portion of our workforce is currently eligible or will reach retirement eligibility within the next five years, and therefore, we are focused on efforts to attract, train, and retain appropriately qualified and skilled workers to prevent loss of institutional knowledge or skills gaps.
NW Natural seeks to provide its employees with growth and development opportunities through programs designed to build skills and relationships. These programs currently include: (i) a culturally relevant mentoring program that creates opportunities for career growth by building relationships; (ii) a tuition assistance program for qualified educational pursuits; (iii) an internal class that provides participants with a big-picture understanding of the industry and company operations, equipping them to see how they contribute to NW Natural’s success and identify opportunities for career growth; (iv) internal and external continuing educational courses relevant to areas of expertise; and (v) ongoing management and leadership training programs.
We regularly monitor employee engagement and satisfaction through a variety of tools, including our annual engagement survey that is designed to enable company leaders to gather valuable feedback and guidance from employees.
Diversity, Equity and Inclusion
We have a longstanding commitment to creating a diverse and inclusive culture that reflects and supports the communities we serve, and believe a diverse, equitable, and inclusive workforce at all levels contributes to long-term success. Our efforts in recruiting, promoting, and retaining diverse talent, building inclusive teams, and creating a culture that embraces differences are elements of our workforce strategy.

ITEM 1A. RISK FACTORS
NW Holdings’ and NW Natural’s business and financial results are subject to a number of risks and uncertainties, many of which are not within our control, which could adversely affect our business, financial condition, and results of operations. Additional risks and uncertainties that are not currently known to us or that are not currently believed by us to be material may also harm our businesses, financial condition, and results of operations. When considering any investment in NW Holdings’ or NW Natural’s securities, investors should carefully consider the following information, as well as information contained in the caption "Forward-Looking Statements", Item 7A, and our other documents filed with the SEC. This list is not exhaustive and the order of presentation does not reflect management’s determination of priority or likelihood. Additionally, our listing of risk factors that primarily affects one of our businesses does not mean that such risk factor is inapplicable to our other businesses.
Legal, Regulatory and Legislative Risks
REGULATORY RISK. Regulation of NW Holdings’ and NW Natural’s regulated businesses, including changes in the regulatory environment, failure of regulatory authorities to approve rates which provide for timely recovery of costs and an adequate return on invested capital, or an unfavorable outcome in regulatory proceedings may adversely impact NW Holdings’ and NW Natural’s financial condition and results of operations.
The OPUC and WUTC have general regulatory authority over NW Natural’s gas business in Oregon and Washington. In January 2025, NW Holdings acquired SiEnergy Operating, LLC (SiEnergy), which is regulated by the Railroad Commission of Texas. NW Holdings’ regulated water utility businesses are generally regulated by the public utility commission in the state in which a water business is located. These public utility commissions have broad regulatory authority, including: the rates charged to customers; authorized rates of return on rate base, including ROE; the amounts and types of securities that may be issued by our regulated utility companies, like NW Natural; services our regulated utility companies provide and the manner in which they provide them; the nature of investments our utility companies make; deferral and recovery of various expenses, including, but not limited to, pipeline replacement, environmental remediation and compliance costs, capital, information technology and other investments, commodity hedging expense, and certain employee benefit expenses such as pension costs; transactions with affiliated interests; regulatory adjustment mechanisms such as weather adjustment mechanisms, and other matters. The OPUC also regulates actions investors may take with respect to our utility companies, NW Natural and NW Holdings. Similarly, FERC has regulatory authority over NW Natural’s interstate storage services. Expansion of our businesses generally results in regulation by other regulatory authorities. For example, certain of NW Holdings’ water companies are regulated in Idaho, Texas and Arizona, and in 2025, we acquired SiEnergy, which is regulated by the Railroad Commission of Texas.
The costs that are deemed recoverable in rates and prices regulators allow us to charge for regulated utility service, and the maximum FERC-approved rates FERC authorizes us to charge for interstate storage and related transportation services, are the most significant factors affecting both NW Natural’s and NW Holdings’ financial position, results of operations and liquidity. State utility regulators have the authority to disallow recovery of costs they find imprudently incurred or otherwise disallowed, and rates that regulators allow may be insufficient for recovery of costs we incur. We expect to continue to make expenditures to expand, improve and safely operate our gas and water utility distribution and gas storage systems, and to work toward reducing emissions from our gas systems. Regulators can deny recovery of those costs. Furthermore, while each applicable state regulator has established an authorized rate of return for our regulated utility businesses, we may not be able to achieve the earnings level authorized. Moreover, in the normal course of business we may place assets in service or incur higher than expected levels of operating expense before rate cases can be filed to recover those costs (this is commonly referred to as regulatory lag). The failure of any regulatory commission to approve requested rate increases on a timely basis to recover costs or to allow an adequate return could adversely impact NW Holdings’ or NW Natural’s financial condition, results of operations and liquidity.
As companies with regulated utility businesses, we frequently have dockets open with our regulators, including NW Natural’s general rate case filed with the OPUC in December 2024. The regulatory proceedings for these dockets typically involve multiple parties, including governmental agencies, consumer, environmental, and other advocacy groups, and other third parties. Each party advocates for the interests that they represent, which may include lower rates, additional regulatory oversight over the company, limitations on growth or phasing out of the gas system, decisions that favor electrification, or advancing other interests.
We cannot predict the timing or outcome of these proceedings, or the effects of those outcomes on NW Holdings’ and NW Natural’s results of operations and financial condition.
REGULATION, COMPLIANCE AND TAXING AUTHORITY RISK. NW Holdings and NW Natural are subject to governmental regulation, and compliance with local, state and federal requirements, including taxing requirements, and unforeseen changes in or interpretations of such requirements could affect NW Holdings’ or NW Natural’s financial condition and results of operations.
NW Holdings and NW Natural are subject to regulation by federal, state and local governmental authorities. We are required to comply with a variety of laws and regulations and to obtain authorizations, permits, approvals and certificates from governmental agencies in various aspects of our business. Significant changes in federal, state, or local governmental leadership can accelerate or amplify changes in existing laws or regulations, or the manner in which they are interpreted or enforced. For instance, the 2024 United States Presidential election has resulted in and may result in further leadership changes in many federal administrative agencies. Moreover, the 2024 election resulted in Republican control of the presidency and both houses of Congress, which may result in a wide range of new policies, executive orders, rules, initiatives and other changes to fiscal, tax, regulation, trade, environmental, climate and other federal policies, many of which have components that affect the energy and utilities sectors. Similarly, we could continue to face significant legislative, regulatory and other policy changes at the state level or in the local jurisdictions in which we operate. For example, the Oregon legislature is considering possible legislation aimed at addressing utility customer rate impacts and utility regulatory oversight. We cannot predict the impact of any such legislation on our rate structure, process or ability to apply regulatory accounting mechanisms. As we continue to expand our businesses into new states, we may be subject to additional legal, regulatory or taxing requirements. For example, certain of NW Holdings’ water companies are regulated in Idaho, Texas and Arizona, and in 2025, we acquired SiEnergy, a gas utility located in Texas. In addition, foreign governments may implement changes to their policies, in response to changes to U.S. policy or otherwise. Although we cannot predict the impact, if any, of these changes to our businesses, they could adversely affect NW Holdings’ or NW Natural’s financial condition and results of operations. Until we know what policy changes are made and how those changes impact our businesses and the business of our competitors over the long term, we will not know if, overall, we will benefit from them or will be negatively affected by them.
We cannot predict changes in laws, regulations, interpretations or enforcement or the impact of such changes. Additionally, any failure to comply with existing or new laws and regulations could result in fines, penalties or injunctive measures. For example, under the Energy Policy Act of 2005, the FERC may assess civil penalties under the Natural Gas Act for violations of FERC’s requirements up to nearly $1.6 million per day for each violation. In addition, as we expand our businesses and the regulatory environment for our businesses increases in complexity, the risk of inadvertent noncompliance may also increase. Changes in regulations, the imposition of additional regulations, and the failure to comply with laws and regulations could negatively influence NW Holdings’ or NW Natural’s operating environment and results of operations. There is uncertainty as to how our regulators will reflect the impact of the legislation and other government regulation in rates. The resulting ratemaking treatment may negatively affect NW Holdings’ or NW Natural’s financial condition and results of operations.
Additionally, changes in federal, state, local or foreign tax laws and their related regulations, or differing interpretations or enforcement of applicable law by a federal, state, local or foreign taxing authority, could result in substantial cost to us and negatively affect our results of operations. Tax law and its related regulations and case law are inherently complex and dynamic. Disputes over interpretations of tax laws may be settled with the taxing authority in examination, through programs like the Compliance Assurance Process (CAP), upon appeal or through litigation. Our judgments may include reserves for potential adverse outcomes regarding tax positions that have been or plan to be taken that may be subject to challenge by taxing authorities. Changes in laws, regulations or adverse judgments and the inherent difficulty in quantifying potential tax effects of business decisions may negatively affect NW Holdings’ or NW Natural’s financial condition and results of operations.
Furthermore, certain tax assets and liabilities, such as deferred tax assets and regulatory tax assets and liabilities, are recognized or recorded by NW Holdings or NW Natural based on certain assumptions and determinations made based on available evidence, such as projected future taxable income, tax-planning strategies, and results of recent operations. If these assumptions and determinations prove to be incorrect, the recorded results may not be realized, which may negatively impact the financial results of NW Holdings and NW Natural.
REPUTATIONAL RISKS. To the extent that customers, legislators, or regulators have or develop a negative opinion of our businesses, NW Holdings’ and NW Natural’s financial position, results of operations and cash flows could be adversely affected.
A number of factors can affect customers’, legislators’, regulators’, and other third parties’ perception of us or our business including: service interruptions or safety concerns due to failures of equipment or facilities or from other causes, and our ability to promptly respond to such failures; our ability to safeguard sensitive customer information; the timing and magnitude of rate increases; and volatility of rates. Customers', legislators', and regulators' opinions of us can also be affected by media coverage, including social media, which may include information, whether factual or not, that could damage the perception of natural gas, our brand, or our reputation.
Although we believe that natural gas serves an important role in helping our region reduce GHG emissions and move to a more resilient lower-carbon energy system, certain advocacy groups have opposed the use of natural gas as a fuel source altogether and have pursued policies that limit, restrict, or impose additional costs on, the use of natural gas in a variety of contexts.
Concerns raised about the use of natural gas include the potential for natural gas explosions or delivery disruptions, methane leakage along production, transportation and delivery systems, and end-use equipment, and contribution of natural gas energy use to GHG emission levels and global warming. Similarly, concerns have also been raised regarding the use of RNG or hydrogen in place of conventional natural gas. In addition, studies and claims by advocacy groups contend that there are detrimental indoor public health effects associated with the use of natural gas, which may also impact public perception. Shifts in public sentiment due to these concerns or others that may be raised may impact further legislative initiatives, regulatory actions, and litigation, as well as behaviors and perceptions of customers, investors, lawmakers, and regulators.
If customers, legislators, regulators, or other third parties have or develop a negative opinion of us and our services, or of natural gas as an energy source generally, this could make it more difficult for us to achieve policy, legislative or regulatory outcomes supportive of our business. Negative opinions could also result in reduced customer growth, sales volumes reductions, increased use of other sources of energy, or difficulties in accessing capital markets. Any of these consequences could adversely affect NW Holdings’ or NW Natural’s financial position, results of operations and cash flows.
REGULATORY ACCOUNTING RISK. In the future, NW Holdings or NW Natural may no longer meet the criteria for continued application of regulatory accounting practices for all or a portion of our regulated operations.
If we can no longer apply regulatory accounting, we could be required to write off our regulatory assets and precluded from the future deferral of costs not recovered through rates at the time such amounts are incurred, even if we are expected to recover these amounts from customers in the future.
The criteria for the application of regulatory accounting is highly specific, and legislative or regulatory changes to our rate structure or processes could impact our ability to apply regulatory accounting in the future.
Growth and Strategic Risks
STRATEGIC TRANSACTION RISK. NW Holdings’ and NW Natural’s ability to successfully complete strategic transactions is subject to significant risks, which could adversely affect NW Holdings’ or NW Natural’s financial condition, results of operations, and cash flows.
From time to time, NW Holdings and NW Natural have pursued and may continue to pursue strategic transactions including mergers, acquisitions, combinations, divestitures, joint ventures, business development projects or other strategic transactions, including, but not limited to, investments in RNG projects on a regulated basis by NW Natural and on a non-regulated basis by NW Holdings, as well as acquisitions by NW Holdings in the water, wastewater and water services, or in the gas or other utility sectors. Any such transactions involve substantial risks, including the following:
•such transactions that are contracted for may fail to close for a variety of reasons;
•the result of such transactions may not produce revenues, earnings or cash flow at anticipated levels, which could, among other things, result in the impairment of any investments or goodwill associated with such transactions;
•acquired businesses or assets could have environmental, permitting, or other problems for which contractual protections prove inadequate;
•our forecasts and projections regarding customer and business growth, financial performance, or economic and market conditions may prove to be incorrect;
•there may be difficulties in integration or higher than expected operation costs of new businesses;
•there may exist liabilities that were not disclosed to us, that exceed our estimates, or for which our rights to indemnification from the seller are limited;
•we may be unable to obtain the necessary regulatory or governmental approvals to close a transaction or receive approvals granted subject to terms that are unacceptable to us;
•we may be unable to achieve the anticipated regulatory treatment of any such transaction as part of the transaction approval or subsequent to closing the transaction; or
•we may be unable to avoid a disposition of assets for a price that is less than the book value of those assets.
One or more of these risks could affect NW Holdings’ and NW Natural’s financial condition, results of operations, and cash flows. For example, in January 2025, we completed the acquisition of SiEnergy, and while we consider this acquisition to be an important component of our growth strategy, we may face unexpected costs or challenges associated with integration of the business or otherwise fail to achieve the expected benefits of the transaction.
BUSINESS DEVELOPMENT RISK. NW Holdings’ and NW Natural’s business development projects may not be successful or may encounter unanticipated obstacles, costs, changes or delays that could result in a project being unsuccessful or becoming impaired, which could negatively impact NW Holdings’ or NW Natural’s financial condition, results of operations and cash flows.
Business development projects involve many risks. We are currently engaged in several business development projects, including, but not limited to, several water, wastewater, water services and RNG projects, non-regulated investments in RNG projects, and purchasing, marketing and reselling of RNG and its associated attributes. We may also engage in other business development projects such as investments in additional long-term gas reserves, gas storage projects, CNG refueling stations, power to gas, power generation, hydrogen projects, carbon capture projects, geothermal projects or other similar projects. Our business development activities are subject to uncertainties and changed circumstances and may not reach the scale expected,
be successful or perform as anticipated. Additionally, we may not be able to obtain required governmental permits and approvals to complete our projects in a cost-efficient or timely manner, potentially resulting in delays or abandonment of the projects. We could also experience issues such as: technological challenges; ineffective scalability; failure to achieve expected outcomes; unsuccessful business models; startup and construction delays; construction cost overruns; reliance on or inability to direct third parties; disputes with contractors or other third parties; the inability to negotiate acceptable agreements such as rights-of-way, easements, construction, gas supply or other material contracts; failure or delay in receiving applicable permits; changes in customer demand, perception or commitment; public opposition to projects; marketing risk and changes in market regulation, behavior or prices, market volatility or unavailability, including markets for RNG and its associated attributes or other environmental attributes; the inability to receive expected tax or regulatory treatment (including any applicable tax incentives or credits for renewable fuels); and operating cost increases. Additionally, we may be unable to finance our business development projects at acceptable costs or within a scheduled time frame necessary for completing the project. Any of the foregoing risks, if realized, could result in business development efforts failing to produce expected financial results and the project investment becoming impaired, and such failure or impairment could have an adverse effect on NW Holdings’ or NW Natural’s financial condition and results of operations.
JOINT PARTNER RISK. Investing in business development projects through partnerships, joint ventures or other business arrangements affects our ability to manage certain risks and could adversely impact NW Holdings’ or NW Natural’s financial condition, results of operations and cash flows.
We use joint ventures and other business arrangements to manage and diversify the risks of certain development projects and investments, including NW Natural’s gas reserves agreements, certain RNG projects, and certain of NW Holdings’ subsidiaries’ unregulated RNG projects and water platform investments. For example, in 2020, NW Natural began a partnership with BioCarbN to invest up to an estimated $38 million in four separate RNG development projects that access biogas derived from water treatment at Tyson Foods' processing plants, subject to approval by all parties. NW Holdings or NW Natural currently has and may further acquire or develop part-ownership interests in other projects in the future, including but not limited to, natural gas, water, wastewater, water services, RNG, or hydrogen projects. Under these arrangements, we may not be able to fully direct the management and policies of the business relationships, and other participants in those relationships may act contrary to our interests, including making operational decisions that could negatively affect our costs and liabilities. In addition, other participants may withdraw from the project, divest important assets, become financially distressed or bankrupt, be subject to additional regulatory or legal requirements, or have economic or other business interests or goals that are inconsistent with ours. We have in the past and may in the future become involved in disputes with our business partners, which could result in additional cost or divert management’s attention.
NW Natural’s gas reserves arrangements, which operate as a hedge backed by physical gas supplies, involve a number of risks, including: gas production that is significantly less than the expected volumes, or no gas volumes; operating costs that are higher than expected; inherent risks of gas production, including disruption to operations or a complete shut-in of the field; and one or more participants in one of these gas reserves arrangements becoming financially insolvent or acting contrary to NW Natural’s interests. For example, Jonah Energy, the counterparty in NW Natural’s gas reserves arrangement, no longer maintains any company credit ratings. Although NW Natural intends to continue monitoring Jonah Energy’s financial condition and take appropriate actions to preserve NW Natural’s interests, it does not control Jonah Energy’s financial condition or continued performance under the gas reserves arrangement. The cost of the original gas reserves venture is currently included in customer rates and additional wells under that arrangement are recovered at specific costs, the occurrence of one or more of these risks could affect NW Natural’s ability to recover this hedge in rates. Further, new gas reserves arrangements have not been approved for inclusion in rates, and regulators may ultimately determine to not include all or a portion of future transactions in rates. The realization of any of these situations could adversely impact NW Holdings’ or NW Natural’s financial condition, results of operations and cash flows.
CUSTOMER GROWTH RISK. NW Holdings’ and NW Natural’s NGD margin, earnings and cash flow may be negatively affected if we are unable to sustain customer growth rates in our NGD segment.
NW Natural’s NGD margins and earnings growth have largely depended upon the sustained growth of its residential and commercial customer base due, in part, to the new construction housing market, conversions of customers to natural gas from other energy sources and growing commercial use of natural gas. Building codes recently enacted and others under consideration in our territory may have the effect of reducing our natural gas customer growth rate. For example, building codes implemented in Washington, if determined to be valid, would have the effect of restricting or eliminating the use of gas space and water heating in new commercial and residential construction, or otherwise increasing the cost of new home construction incorporating natural gas. Certain jurisdictions in Oregon and Washington are considering similar measures. While we expect these types of codes to be subject to legal challenge, we cannot predict the outcome of any such challenge. Other regulations may impact growth; for example, in connection with the resolution of NW Natural’s general rate case, on October 25, 2024, the OPUC issued an order ordering the phase out of NW Natural’s line extension allowance by November 1, 2027. We are not currently able to quantify the extent to which limitations on natural gas use, or declining line extension allowances provided in rates to cover construction costs for new services, will affect new meter additions, or to what extent carbon compliance costs included in rates will affect the competitiveness of our business and the demand for natural gas service. Insufficient customer growth, for economic, political, public perception, policy, or other reasons could adversely affect NW Holdings’ or NW Natural’s utility margin, earnings and cash flows.
RISK OF COMPETITION. Our NGD business is subject to increased competition which could negatively affect NW Holdings’ or NW Natural’s results of operations.
In the residential and commercial markets, our natural gas distribution businesses compete primarily with suppliers of electricity, fuel oil, and propane. In the industrial market, we compete with suppliers of all forms of energy. Competition among these forms of energy is based on price, efficiency, reliability, performance, market conditions, technology, federal, state and local governmental regulation, actual and perceived environmental impacts, and public perception. Technological improvements such as electric heat pumps, batteries or other alternative technologies, or building code or other regulations or restrictions affecting the cost or ability to use certain gas appliances, could erode our competitive advantage. If natural gas prices are high relative to other energy sources, or if the cost, environmental impact or public perception of such other energy sources improves relative to natural gas, it may negatively affect our ability to secure new customers or retain our existing customers, which could have a negative impact on our customer growth rate and NW Holdings’ and NW Natural’s results of operations.
Our natural gas storage operations compete primarily with other storage facilities and pipelines. Increased competition in the natural gas storage business could reduce the demand for our natural gas storage services, drive prices down for our storage business, and adversely affect our ability to renew or replace existing contracts at rates sufficient to maintain current revenues and cash flows, which could adversely affect NW Holdings’ and NW Natural’s financial condition, results of operations and cash flows.
Operational Risks
OPERATING RISK. Transporting and storing gas and liquid fuels and distributing gas and liquid fuels and, water and wastewater involves numerous risks that may result in accidents and other operating risks and costs, some or all of which may not be fully covered by insurance, and which could adversely affect NW Holdings’ or NW Natural’s financial condition, results of operations and cash flows.
NW Holdings and NW Natural are subject to all of the risks and hazards inherent in the businesses of gas and liquid transmission, distribution and storage, water distribution, and water and wastewater services including:
•earthquakes, wildfires, floods, storms, landslides and other severe weather incidents and natural hazards;
•leaks or losses of gases or liquids, or contamination of gases or liquids by chemicals or compounds, as a result of the malfunction of equipment or facilities or otherwise;
•operator errors or damages from third parties;
•negative performance by our storage reservoirs, facilities, or wells that could cause us to fail to meet expected or forecasted operational levels or contractual commitments to our customers or other third parties;
•problems maintaining, or the malfunction of, pipelines, biodigester facilities, wellbores and related equipment and facilities that form a part of the infrastructure that is critical to the operation of our facilities;
•presence of chemicals or other compounds in the gases or liquids we deliver that could adversely affect the performance of the system or end-use equipment;
•failure of gas or water storage reservoirs;
•inadequate supplies of RNG, natural gas or water or contamination of water supplies;
•operating costs that are substantially higher than expected;
•supply chain disruptions, including unexpected price increases, or supply restrictions beyond the control of our suppliers;
•migration of gas through faults in the rock or to some area of the reservoir where existing wells cannot drain the gas effectively, resulting in loss of the gas;
•blowouts (uncontrolled escapes of gas from a pipeline or well) or other accidents, fires and explosions; and
•risks and hazards inherent in the drilling operations associated with the development of gas storage facilities, and wells.
For example, TC Pipelines, LP (TC Pipelines) has identified the presence of a chemical substance, dithiazine, at several facilities on the system of its subsidiary, Gas Transmission Northwest (GTN), and those of some upstream and downstream connecting pipeline facilities. A portion of NW Natural’s gas supplies from Canada are transported on GTN’s pipelines. TC Pipelines reports that dithiazine can drop out of gas streams in a powdery form at some points of pressure reduction (for example, at a regulator), and that in incidents where a sufficient quantity of the material accumulates in certain places, improper functioning of equipment can occur, which can result in increased preventative and corrective action costs. While NW Natural has not detected significant quantities of dithiazine on its system to date, we continue to monitor and could discover increased levels of dithiazine or other compounds on NW Natural’s system that could affect the performance of the system or end-use equipment.
These and other operational risks could result in disruption of service, personal injury or loss of human life, damage to and destruction of property and equipment, pollution or other environmental damage, breaches of our contractual commitments, and may result in curtailment or suspension of operations, which in turn could lead to significant costs and lost revenues. Further, because our pipeline, storage and distribution facilities are in or near populated areas, including residential areas, commercial business centers, and industrial sites, any loss of human life or adverse financial outcomes resulting from such events could be significant. We could be subject to lawsuits, claims, and criminal and civil enforcement actions. Additionally, we may not be able to maintain the level or types of insurance we desire, and the insurance coverage we do obtain may contain large deductibles or fail to cover certain hazards or cover all potential losses. The occurrence of any operating risks not covered by insurance could adversely affect NW Holdings’ or NW Natural’s financial condition, results of operations and cash flows.
SAFETY REGULATION RISK. NW Holdings and NW Natural may experience increased federal, state and local regulation of the safety of our systems and operations, which could adversely affect NW Holdings’ or NW Natural’s operating costs and financial results.
The safety and protection of the public, our customers and our employees is and will remain our top priority. We are committed to consistently monitoring, maintaining, and upgrading our distribution systems and storage operations to ensure that RNG, natural gas and water is acquired, stored and delivered safely, reliably and efficiently. Natural gas operators are subject to robust, ongoing federal, state and local regulatory oversight, which intensifies in response to incidents. For example, the 2020 Protecting our Infrastructure of Pipelines and Enhancing Safety Act (PIPES Act) prompted PHSMA to issue three rulemakings impacting transmission lines, gathering lines, and valve automation in response to past incidents in other parts of the country. Regulations issued in 2024 by PHMSA contain requirements related to the detection and repair of leaks and safety of gas distribution pipelines.
In addition, our workplaces are subject to the requirements of the Department of Transportation, through the Federal Motor Carrier Safety Administration, and the Occupational Safety and Health Administration, as well as state and local statutes and regulations that regulate the protection of the health and safety of workers. The failure to comply with these requirements or general industry standards, including keeping adequate records or preventing occupational injuries or exposure, could expose us to civil or criminal liability, enforcement actions, and regulatory fines and penalties that may not be recoverable through our rates and could have a material adverse effect on our business, financial condition, results of operations and cash flows.
We intend to work diligently with industry associations and federal and state regulators to comply with these regulations and other new laws. We expect there to be increased costs associated with compliance, and those costs could be significant. If these costs are not recoverable in our customer rates, they could have a negative impact on NW Holdings’ and NW Natural’s operating costs and financial results.
RELIANCE ON THIRD PARTIES TO SUPPLY OR OPTIMIZE NATURAL GAS, RNG AND ENVIRONMENTAL ATTRIBUTES OR CREDITS RISK. We rely on third parties to supply or optimize natural gas, RNG, storage or pipeline capacity, and environmental attributes or credits in our NGD segment, and limitations on our ability to obtain supplies, engage in effective optimization, or failure to receive expected supplies, could have an adverse impact on NW Holdings’ or NW Natural’s financial results.
Our ability to secure natural gas, RNG and environmental attributes or credits depends upon its ability to purchase and receive delivery of them from third parties. We, and in some cases our suppliers, do not have control over the availability of natural gas, RNG or environmental attributes or credits, competition for those supplies, disruptions in those supplies, priority allocations on transmission pipelines, markets for those supplies, or pricing and other terms related to such supplies. Additionally, third parties that we may rely on may fail to deliver supplies for which it has contracted. For example, in October, 2018, a 36-inch pipeline near Prince George, British Columbia owned by Enbridge ruptured, disrupting natural gas flows from Canada into Washington while the ruptured pipeline and an adjacent pipeline were assessed and the ruptured pipeline was repaired. Once repaired, pressurization levels for those pipelines were reduced for a significant period of time for assessment and testing. If we are unable or limited in our ability to obtain natural gas, RNG or environmental attributes or credits from our current suppliers or new sources, we may not be able to meet customers' gas requirements or regulatory or compliance requirements, and would likely incur costs associated with actions necessary to mitigate service disruptions or regulatory compliance, which could significantly and negatively impact NW Holdings’ and NW Natural’s results of operations.
We also contract with an independent energy marketing company to provide asset management services regarding storage and pipeline capacity when those assets are not serving the needs of NGD business customers. We may not be able to fully direct these transactions, or the counterparty to these arrangements may act contrary to our interests, become financially distressed or have economic or other business interests or goals that are inconsistent with ours. Failure to effectively optimize our assets could result in a negative impact on NW Holdings' and NW Natural’s financial condition, revenues and results of operations.
SINGLE TRANSPORTATION PIPELINE RISK. NW Natural relies on a single pipeline company for the transportation of gas to its service territory, a disruption, limitation, or inadequacy of which could adversely impact its ability to meet customers’ gas requirements, which could significantly and negatively impact NW Holdings’ and NW Natural’s results of operations.
NW Natural’s distribution system is directly connected to a single interstate pipeline, which is owned and operated by Northwest Pipeline. The pipeline’s gas flows are bi-directional, transporting gas into the Portland metropolitan market from two directions: (1) the north, which brings supplies from the British Columbia and Alberta supply basins; and (2) the east, which brings supplies from the Alberta and the U.S. Rocky Mountain supply basins. If there is a rupture or inadequate capacity in, or supplies to maintain adequate pressures in, the pipeline, NW Natural may not be able to meet its customers’ gas requirements and we would likely incur costs associated with actions necessary to mitigate service disruptions, both of which could significantly and negatively impact NW Holdings’ and NW Natural’s results of operations.
THIRD PARTY PIPELINE RISK. NW Natural’s gas storage business depends on third-party pipelines that connect our storage facilities to interstate pipelines, the failure or unavailability of which could adversely affect NW Holdings’ or NW Natural’s financial condition, results of operations and cash flows.
Our gas storage facilities are reliant on the continued operation of a third-party pipeline and other facilities that provide delivery options to and from our storage facilities. Because we do not own all of these pipelines, their operations are not within our control. If the third-party pipeline to which we are connected were to become unavailable for current or future withdrawals or injections of natural gas due to repairs, damage to the infrastructure, lack of capacity or other reasons, our ability to operate efficiently and satisfy our customers’ needs could be compromised, thereby potentially having an adverse impact on NW Holdings’ or NW Natural’s financial condition, results of operations and cash flows.
WORKFORCE RISK. NW Holdings’ and NW Natural’s businesses are heavily dependent on being able to attract and retain qualified employees and maintain a competitive cost structure with market-based salaries and employee benefits, and workforce disruptions could adversely affect NW Holdings’ or NW Natural’s operations and results.
NW Holdings’ and NW Natural’s ability to implement our business strategy and serve our customers is dependent upon our continuing ability to attract and retain diverse, talented professionals and a technically skilled workforce, and being able to transfer the knowledge and expertise of our workforce to new and increasingly diverse employees as our largely older workforce retires. A significant portion of our workforce is currently eligible or will reach retirement eligibility within the next five years, which will require that we attract, train and retain skilled workers to prevent loss of institutional knowledge or skills gaps. We face competition for qualified personnel with specific skillsets. This competition may result in increased pressure on wages or other challenges in recruiting or retaining personnel. Without an appropriately skilled workforce, our ability to provide quality service and meet our regulatory requirements will be challenged and this could negatively impact NW Holdings' and NW Natural’s earnings. Additionally, approximately half of NW Natural workers are represented by the OPEIU Local No. 11 AFL-CIO and are covered by a collective bargaining agreement that extends to May 31, 2028. Disputes with the union representing NW Natural employees over terms and conditions of their agreement, or failure to timely and effectively renegotiate the agreement upon its expiration, could result in instability in our labor relationship or other labor disruptions or work stoppages that could impact the timely delivery of gas and other services from our utility and storage facilities, which could strain relationships with customers and state regulators and cause a loss of revenues. The collective bargaining agreements may also limit our flexibility in dealing with NW Natural’s workforce, and the ability to change work rules and practices and implement other efficiency-related improvements to successfully compete in today’s challenging marketplace, which may negatively affect NW Holdings’ and NW Natural’s financial condition and results of operations.
Environmental Risks
ENVIRONMENTAL LIABILITY RISK. Certain of NW Natural’s, and possibly NW Holdings’, properties and facilities may pose environmental risks requiring remediation, the costs of which are difficult to estimate and which could adversely affect NW Holdings’ and NW Natural’s financial condition, results of operations, and cash flows.
NW Natural owns, or previously owned, properties that require environmental remediation or other action. NW Holdings or NW Natural may now, or in the future, own other properties that require environmental remediation or other action. NW Natural and NW Holdings accrue all material loss contingencies relating to these properties. A regulatory asset at NW Natural has been recorded for estimated costs pursuant to a deferral order from the OPUC and WUTC. In addition to maintaining regulatory deferrals, NW Natural settled with most of its historical liability insurers for only a portion of the costs it has incurred to date and expects to incur in the future. To the extent amounts NW Natural recovered from insurance are inadequate and it is unable to recover these deferred costs in utility customer rates, NW Natural would be required to reduce its regulatory assets which would result in a charge to earnings in the year in which regulatory assets are reduced. In addition, in Oregon, the OPUC approved the SRRM, which limits recovery of deferred amounts to those amounts which satisfy an annual prudence review and an earnings test that requires NW Natural to contribute additional amounts toward environmental remediation costs above approximately $10 million in years in which NW Natural earns above its authorized ROE. To the extent NW Natural earns more than its authorized ROE in a year, it would be required to cover environmental expenses greater than the $10 million with those earnings that exceed its authorized ROE. The OPUC ordered a review of the SRRM in 2018 or when we obtain greater certainty of environmental costs, whichever occurred first. We submitted information for review in 2018, and believe we could be subject to further review. Similarly, in October 2019, the WUTC authorized an ECRM, which allows for recovery of certain past deferred and future prudently incurred remediation costs allocable to Washington through application of insurance proceeds and collections from customers, subject to an annual prudence determination. These ongoing prudence reviews, or with respect to the SRRM, the earnings test, or the periodic review could reduce the amounts NW Natural is allowed to recover, and could adversely affect NW Holdings’ or NW Natural’s financial condition, results of operations and cash flows.
Moreover, we may have disputes with regulators and other parties as to the severity of particular environmental matters, what remediation efforts are appropriate, whether natural resources were damaged, and the portion of the costs or claims NW Natural or NW Holdings should bear. We cannot predict with certainty the amount or timing of future expenditures related to environmental investigations, remediation or other action, the portions of these costs allocable to NW Natural or NW Holdings, or disputes or litigation arising in relation thereto.
Environmental liability estimates are based on current remediation technology, industry experience gained at similar sites, an assessment of probable level of responsibility, and the financial condition of other potentially responsible parties. However, it is difficult to estimate such costs due to uncertainties surrounding the course of environmental remediation, the preliminary nature of certain site investigations, natural recovery of the site, unavoidable limitations associated with environmental investigations and remedial technologies, evolving science, the application of environmental laws that impose joint and several liabilities on all
potentially responsible parties, and changes in federal, state or local environmental statutes, regulations or policies. These uncertainties and disputes arising therefrom could lead to further adversarial administrative proceedings or litigation, with associated costs and uncertain outcomes, all of which could adversely affect NW Holdings’ or NW Natural’s financial condition, results of operations and cash flows.
ENVIRONMENTAL REGULATION COMPLIANCE RISK. NW Holdings and NW Natural are subject to environmental regulations, compliance with which or failure to comply with, could adversely affect our operations or financial results.
NW Holdings and NW Natural are subject to laws, regulations and other legal requirements enacted or adopted by federal, state and local governmental authorities relating to protection of the environment, including those legal requirements that govern discharges of substances into the air and water, the management and disposal of hazardous substances and waste, groundwater quality and availability, plant and wildlife protection, the emitting of greenhouse gases, and other aspects of environmental regulation. For example, our natural gas operations are subject to reporting requirements to a number of governmental authorities including, but not limited to, the Environmental Protection Agency (EPA), the Oregon Department of Environmental Quality (ODEQ), and the Washington State Department of Ecology regarding greenhouse gas emissions. We are also required to reduce emissions of GHGs over time in accordance with the recently issued Oregon Climate Protection Program (CPP) and the Washington Climate Commitment Act (CCA). We expect that compliance with any form of regulation of GHG emissions will require additional resources and legislative or regulatory tools and will increase costs. The developing and changing guidance to implement the CCA and CPP, evolving carbon credit markets and other regulatory tool options, decades-long timeframes for compliance, likely changing and evolving laws and energy policy, and evolving technological advancements, all make it difficult to accurately predict long-term tools for and costs of compliance. Increased compliance costs or additional operating restrictions resulting from current and future additional environmental regulations at the local, state or national level may or may not be recoverable in customer rates, through insurance or otherwise. If these costs are not recoverable, or if these regulations reduce the desirability, availability, or cost-competitiveness of natural gas, they could have an adverse effect on NW Holdings’ or NW Natural’s operations or financial condition. Furthermore, failure to comply with such laws or regulations could subject us to possible enforcement actions, financial liability or litigation, any of which could adversely affect NW Holdings’ or NW Natural’s financial condition and results of operations.
GLOBAL CLIMATE CHANGE RISK. Our businesses may be subject to physical risks associated with climate change, all of which could adversely affect NW Holdings’ or NW Natural’s financial condition, results of operations and cash flows.
Climate change may cause physical risks, including an increase in sea level, intensified storms, water scarcity, wildfire susceptibility and intensity and changes in weather conditions, such as changes in precipitation, average temperatures and extreme wind or other extreme weather events or climate conditions. Moreover, a significant portion of the nation’s gas infrastructure is located in areas susceptible to storm damage that could be aggravated by wetland and barrier island erosion, which could give rise to gas supply interruptions and price spikes. Fire risk is also significant in the western United States, including in our service territory, and may be elevated by warmer air temperatures, drought, wind and land management practices. Climate change may increase the likelihood and magnitude of damages that may be caused by fires, which may adversely affect our financial condition, results of operations, and cash flows.
These and other physical changes could result in disruptions to natural gas production and transportation systems potentially increasing the cost of gas and affecting our natural gas businesses’ ability to procure or transport gas to meet customer demand. These changes could also affect our distribution systems resulting in increased maintenance and capital costs, disruption of service, regulatory actions and lower customer satisfaction. Similar disruptions could occur in NW Holdings’ water utility and unregulated RNG businesses. To the extent we are unable to recover these costs, or if higher rates resulting from our recovery of such costs result in reduced demand for our services, our future business, financial condition, or financial results could be adversely impacted. Additionally, to the extent that climate change adversely impacts the economic health or weather conditions of our service territory directly, it could adversely impact customer demand or our customers’ ability to pay. Such physical risks could have an adverse effect on NW Holdings’ or NW Natural’s financial condition, results of operations, and cash flows.
PUBLIC PERCEPTION AND POLICY RISK. Changes in public sentiment or public policy with respect to natural gas, including through local, state or federal laws or legislation or other regulation (including ballot initiatives, executive orders or regulatory codes) or litigation, could adversely affect NW Holdings’ or NW Natural’s financial condition, results of operations and cash flows.
There are a number of international, federal, state, and local legislative, legal, regulatory and other initiatives being proposed and adopted in an attempt to measure, control or limit the effects of global warming and climate change, including greenhouse gas (GHG) emissions such as carbon dioxide, nitrous oxide, and methane. Legislation or other forms of public policy or regulation that aim to reduce GHG emissions at the federal, state, or local level have and could continue to take a variety of forms including, but not limited to, GHG emissions limits, reporting requirements, carbon taxes, requirements to purchase carbon credits, building codes, increased efficiency standards, additional charges to fund energy efficiency activities or other regulatory actions, and incentives or mandates to conserve energy, or use renewable energy sources. Federal, state, or local governments may provide tax advantages and other subsidies to support alternative energy sources, withdraw funding from fossil fuel sources, mandate the use of specific fuels or technologies, prohibit the use of natural gas, or promote research into new technologies to reduce the cost and increase the scalability of alternative energy sources. For example, during his administration, former President Biden issued a number of executive orders, and a wide range of federal agencies took action aimed at addressing
climate change and other environmental matters. Federal legislation passed under the Biden administration, such as the Inflation Reduction Act of 2022 (IRA), included several climate and energy provisions. Upon taking office in January, 2025, President Trump issued several executive orders aimed at revoking Biden-era climate policies. We expect there to be a number of additional changes related to climate policy under the Trump Administration, including additional executive orders, federal regulations, programs and other federal actions, however, we cannot currently predict when or if the Trump Administration or Congress will act, the form of the action, the extent to which any such action may replace or revoke prior administration policies, or the impact of those actions on our business.
At the state level, effective beginning in 2023, the State of Washington enacted the Climate Commitment Act (CCA), which establishes a comprehensive program that provides an overall limit for GHG emissions from major sources in the state and declines yearly to 95% below 1990 levels by 2050. NW Natural is currently subject to the CCA. Similarly, in Oregon, In November 2024, the ODEQ issued final cap and reduce rules for its Climate Protection Program (CPP), which became effective January 1, 2025. The CPP establishes a program to limit GHG emissions from covered entities, including natural gas utilities, by 50% by 2035 and 90% by 2050 from a 2017-2019 baseline. In addition, the State of Washington has implemented, and the State of Oregon and some local jurisdictions have considered or are considering, building codes that could have the effect of disfavoring or disallowing natural gas in residential or commercial new construction or conversions, including locations within our service territory. For example, the Eugene City Council continues to develop a plan to address GHG emissions, align incentives around GHG emissions and to engage in a number of actions, including identifying potential revenue sources, like a gas supplier tax. Similarly, some jurisdictions and advocates are evaluating restricting the use of natural gas and certain natural gas appliances inside homes contending that there are detrimental indoor health effects associated with the use of natural gas.
Such current or future legislation, regulation or other initiatives (including executive orders, ballot initiatives or ordinances) could impose on our natural gas businesses operational requirements or restrictions, additional charges to fund energy efficiency initiatives, or levy a tax based on carbon content. In addition, certain jurisdictions, including San Francisco, Seattle, and New York have enacted measures to ban or discourage the use of new natural gas hookups in residential or other buildings. Other jurisdictions, including several in our service territory, have considered or are currently considering similar restrictions or other measures discouraging the use of natural gas, such as limitations or bans on the use of natural gas in new construction, requiring the conversion of buildings to electric heat, or adopting policies or incentives to encourage the use of electricity in lieu of natural gas. Such restrictions could adversely impact customer growth or usage and could adversely impact our ability to recover costs and maintain reasonable customer rates. In addition, certain states, cities, local jurisdictions and private parties have initiated lawsuits against companies related to climate change impacts, GHG emissions or climate-related disclosures. We have been named as a defendant in two such legal proceedings, each as described in more detail in Note 17 to the Consolidated Financial Statements. While we intend to diligently defend against such claims, we cannot predict the outcome of such litigation. Such climate-related claims or actions could be costly to defend and could negatively impact our business, reputation, financial condition, and results of operations.
NW Natural believes natural gas has an important role in moving the Pacific Northwest to a lower carbon future, and to that end is developing programs and measures to reduce carbon emissions. However, NW Natural’s efforts may not happen quickly enough to keep pace with legislation or other regulation, legal changes or public sentiment, or may be more costly or not be as effective as expected. Any of these initiatives, or our unsuccessful response to them, could result in us incurring additional costs to comply with the imposed policies, regulations, restrictions or programs, provide a cost or other competitive advantage to energy sources other than natural gas, reduce demand for natural gas, restrict our customer growth, impose costs or restrictions on end users of natural gas, impact the prices we charge our customers, increase the likelihood of litigation, reduce our access to capital, impose increased costs on us associated with the adoption of new infrastructure and technology to respond to such requirements which may or may not be recoverable in customer rates, and could negatively impact public perception of our services or products that negatively diminishes the value of our brand, all of which could adversely affect NW Holdings’ or NW Natural’s business operations, financial condition and results of operations.
Business Continuity and Technology Risks
BUSINESS CONTINUITY RISK. NW Holdings and NW Natural may be adversely impacted by local or national disasters, pandemics, political unrest, terrorist activities, cyber-attacks or data breaches, and other extreme events to which we may not be able to promptly respond, which could adversely affect NW Holdings’ or NW Natural’s operations or financial condition.
Local or national disasters (including but not limited to earthquakes, wildfires, floods, storms, landslides), pandemics, political unrest, terrorist activities, cyber-attacks and data breaches, power outages, and other extreme events are a threat to our assets and operations. Companies in critical infrastructure industries face a heightened risk due to being the target of, and having heightened exposure to, acts of terrorism or sabotage, including physical and security breaches of our physical infrastructure and information technology or operational technology systems in the form of cyber-attacks or other forms of attacks. These attacks could, among other things, target or impact our technology or mechanical systems that operate our distribution, transmission or storage facilities and result in a disruption in our operations, damage to our system and inability to meet customer requirements. In addition, the threat of terrorist activities could lead to increased economic instability and volatility in the price of RNG, natural gas or other necessary commodities that could affect our operations. Threatened or actual national disasters, pandemics or terrorist activities may also disrupt capital or bank markets and our ability to raise capital or obtain debt financing, or impact our suppliers or our customers directly, including increasing volatility in the price of natural gas or reducing demand for natural gas or water. Local disaster, pandemics, or civil unrest could result in disruption of our infrastructure or facilities, increase our operating
costs, or result in part of our workforce being unable to operate or maintain our infrastructure or perform other tasks necessary to conduct our business. Local disruption may also limit our ability to collect on overdue accounts or disconnect gas or water service for nonpayment beyond an amount or period of time acceptable to us. A slow or inadequate response to events may have an adverse impact on our operations and earnings. We may not be able to maintain sufficient insurance to cover all risks associated with local and national disasters, pandemic illnesses, terrorist activities, cyber-attacks and other attacks or events. Additionally, large scale natural disasters or terrorist attacks could destabilize the insurance industry making the insurance we do have unavailable, which could increase the risk that an event could adversely affect NW Holdings’ or NW Natural’s operations or financial results. Similarly, business disruptions may limit, delay or block public utility commissions’ ability to approve or authorize applications or other requests we may make with respect to our regulated businesses. Any of these occurrences, or the resulting economic effects could have a material adverse effect on our business, outlook, financial condition, and results of operations and cash flows.
RELIANCE ON TECHNOLOGY RISK. NW Holdings’ and NW Natural’s efforts to integrate, consolidate and streamline each of their operations has resulted in increased reliance on technology, the failure of which could adversely affect NW Holdings’ or NW Natural’s financial condition and results of operations.
NW Holdings and NW Natural have undertaken, and will continue to undertake, a variety of initiatives to integrate, standardize, centralize and streamline operations. These efforts have resulted in greater reliance on technological tools such as, at NW Natural: an enterprise resource planning system, technology associated with gas operations, a digital dispatch system, an automated meter reading system, a web-based ordering and tracking system, and other similar technological tools and initiatives. Our future success will depend, in part, on our ability to anticipate and adapt to technological changes in a cost-effective manner and to offer, on a timely basis, services that meet customer demands and evolving industry standards. New technologies may emerge that could be superior to, or may not be compatible with, some of our existing technologies, and may require us to make significant expenditures to remain competitive. We continue to implement technology to improve our business processes and customer interactions. In addition, our various existing information technology systems require periodic modifications, upgrades and/or replacement. For example, NW Natural has recently implemented upgrades to its SAP system and intends to replace its customer information system in the near future.
There are various risks associated with these systems in addition to upgrades and replacements, including hardware and software failure, communications failure, data distortion or destruction, unauthorized access to data, misuse of proprietary or confidential data, unauthorized control through electronic means, programming mistakes and other inadvertent errors or deliberate human acts. In addition, we are dependent on a continuing flow of important components and appropriately skilled individuals to maintain and upgrade our information technology systems. Our suppliers have previously faced disruptions, such as during the COVID-19 pandemic, and may face additional production or import delays due to natural disasters, strikes, lock-outs, political unrest, pandemics or other such circumstances. Technology services provided by third-parties also could be disrupted due to events and circumstances beyond our control which could adversely impact our business, financial condition and results of operations.
Any modifications, upgrades, system maintenance or replacements subject us to inherent costs and risks, including potential disruption of our internal control structure, substantial capital expenditures, additional administrative and operating expenses, retention of sufficiently skilled personnel to implement and operate the new systems, and other risks and costs of delays or difficulties in transitioning to new systems or of integrating new systems into our current systems. In addition, the difficulties with implementing new technology systems may cause disruptions in our business operations and have an adverse effect on our business and operations, if not anticipated and appropriately mitigated. There is also risk that we may not be able to recover all costs associated with projects to improve our technological capabilities, which may adversely affect NW Holdings’ or NW Natural’s financial condition and results of operations.
CYBERSECURITY RISK. NW Holdings’ and NW Natural’s status as an infrastructure services provider coupled with its reliance on technology could result in a security breach which could adversely affect NW Holdings’ or NW Natural’s financial condition and results of operations.
Although we take precautions to protect our technology systems and are not aware of any material security breaches to date, there is no guarantee that the procedures we have implemented to protect against unauthorized access to secured data and systems, including our operational technology and information technology systems, are adequate to safeguard against all security breaches or other cyberattacks. Additionally, the facilities and systems of clients, suppliers and third-party service providers also could be vulnerable to cyber risks and attacks, and such third party systems may be interconnected to our systems. Therefore, an event caused by cyberattacks or other malicious act at an interconnected third party could impact our business and facilities similarly. As these potential cyber security attacks become more common and sophisticated, we could be required to incur costs to strengthen our systems or maintain insurance coverage against potential losses. Moreover, a variety of regulatory agencies are focused on cybersecurity risks, and specifically in critical infrastructure sectors. For example, the Transportation Security Administration (TSA) has published security directives and in November 2024, proposed formal rules mandating cybersecurity actions for critical pipeline owners and operators. Failure to meet the requirements of these directives or other cybersecurity regulations could result in fines or other penalties. We are continuing to evaluate the potential costs of implementation of these directives, and there is no assurance that we will be able to continue to recover in rates costs associated with such compliance.
In addition, our businesses could experience breaches of security pertaining to sensitive customer, employee, and vendor information maintained by us in the normal course of business, which could adversely affect our reputation, diminish customer confidence, disrupt operations, materially increase the costs we incur to protect against these risks, and subject us to possible financial liability or increased regulation or litigation. All of these risks could adversely affect NW Holdings’ or NW Natural’s financial condition and results of operations.
Financial and Economic Risks
HOLDING COMPANY DIVIDEND RISK. As a holding company, NW Holdings depends on its operating subsidiaries, including NW Natural, to meet financial obligations and the ability of NW Holdings to pay dividends on its common stock is dependent on the receipt of dividends and other payments from its subsidiaries, including NW Natural.
As a holding company, NW Holdings’ only significant assets are the stock and membership interests of its operating subsidiaries, which at this time is primarily NW Natural. NW Holdings’ direct and indirect subsidiaries are separate and distinct legal entities, managed by their own boards of directors, and have no obligation to pay any amounts to their respective shareholders, whether through dividends, loans or other payments. The ability of these companies to pay dividends or make other distributions on their common stock is subject to, among other things: their results of operations, net income, cash flows and financial condition, as well as the success of their business strategies and general economic and competitive conditions; the prior rights of holders of existing and future debt securities and any future preferred stock issued by those companies; and any applicable legal restrictions.
In addition, the ability of NW Holdings’ subsidiaries to pay upstream dividends and make other distributions is subject to applicable state law and regulatory restrictions. Under the OPUC and WUTC regulatory approvals for the holding company formation, if NW Natural ceases to comply with credit and capital structure requirements approved by the OPUC and WUTC, it will not, with limited exceptions, be permitted to pay dividends to NW Holdings. Under the OPUC and WUTC orders authorizing the holding company reorganization, NW Natural may not pay dividends or make distributions to NW Holdings if NW Natural’s credit ratings and common equity levels fall below specified ratings and levels. If NW Natural’s long-term secured credit ratings are below A- for S&P and A3 for Moody’s, dividends may be issued so long as NW Natural’s common equity is 45% or above. If NW Natural’s long-term secured credit ratings are below BBB for S&P and Baa2 for Moody’s, dividends may be issued so long as NW Natural’s common equity is 46% or above. Dividends may not be issued if NW Natural’s long-term secured credit ratings fall to BB+ or below for S&P or Ba1 or below for Moody’s, or if NW Natural’s common equity is below 44%. The ratio is measured using common equity and long-term debt excluding imputed debt or debt-like lease obligations, and is determined on a preceding or projected 13-month basis.
EMPLOYEE BENEFIT RISK. The cost of providing pension and postretirement healthcare benefits is subject to changes in pension assets and liabilities, changing employee demographics and changing actuarial assumptions, which may have an adverse effect on NW Holdings’ or NW Natural’s financial condition, results of operations and cash flows.
Until NW Natural closed the pension plans to new hires, which for non-union employees was in 2006 and for union employees was in 2009, it provided pension plans and postretirement healthcare benefits to eligible full-time utility employees and retirees. Approximately 22% of NW Natural’s current utility employees were hired prior to these dates, and therefore remain eligible for these plans. Other businesses we acquire may also have pension plans. The costs to NW Natural, or the other applicable businesses we may acquire, for providing such benefits is subject to change in the market value of the pension assets, changes in employee demographics including longer life expectancies, increases in healthcare costs, current and future legislative changes, and various actuarial calculations and assumptions. The actuarial assumptions used to calculate our future pension and postretirement healthcare expenses may differ materially from actual results due to significant market fluctuations and changing withdrawal rates, wage rates, interest rates and other factors. These differences may result in an adverse impact on the amount of pension contributions, pension expense or other postretirement benefit costs recorded in future periods. Sustained declines in equity markets and reductions in bond rates may have a material adverse effect on the value of the pension fund assets and liabilities. In these circumstances, NW Natural may be required to recognize increased contributions and pension expense earlier than it had planned to the extent that the value of pension assets is less than the total anticipated liability under the plans, which could have a negative impact on NW Holdings’ and NW Natural’s financial condition, results of operations and cash flows.
HEDGING RISK. NW Holdings’ and NW Natural’s risk management policies and hedging activities cannot eliminate the risk of commodity price movements and other financial market risks, and hedging activities may expose us to additional liabilities for which rate recovery may be disallowed, which could result in an adverse impact on NW Holdings’ and NW Natural’s operating revenues, costs, derivative assets and liabilities and operating cash flows.
Our gas purchasing requirements expose us to risks of commodity price movements, while our use of debt and equity financing exposes us to interest rate, liquidity and other financial market risks. We attempt to manage these exposures with both physical hedges, including our storage and gas reserves transactions, which are hedges backed by physical gas supplies, and financial hedges, such as gas swaps and interest rate hedging arrangements. We may also enter into other types of financial and physical hedging arrangements from time to time. While we have risk management procedures for hedging in place, they may not always work as planned and cannot entirely eliminate the risks associated with hedging. Additionally, our hedging activities may cause
us to incur additional expenses to obtain the hedge. We do not hedge our entire interest rate or commodity cost exposure, and the unhedged exposure will vary over time. Gains or losses experienced through NW Natural’s hedging activities, including carrying costs, generally flow through NW Natural’s PGA mechanism or are recovered in future general rate cases. However, the hedge transactions NW Natural enters into for utility purposes are subject to a prudence review by the OPUC and WUTC, and, if found imprudent, those expenses may be, and have been previously, disallowed, which could have an adverse effect on NW Holdings’ or NW Natural’s financial condition and results of operations.
In addition, our actual business requirements and available resources may vary from forecasts, which are used as the basis for hedging decisions and could cause our exposure to be more or less than anticipated. Moreover, if NW Natural’s derivative instruments and hedging transactions do not qualify for regulatory deferral or hedge accounting treatment under U.S. GAAP, NW Holdings’ or NW Natural’s results of operations and financial condition could be adversely affected.
NW Holdings and NW Natural also have credit and performance exposure to derivative counterparties. Counterparties owing NW Holdings, NW Natural or their respective subsidiaries money, physical natural gas, RNG or environmental attributes could breach their obligations. Should the counterparties to these arrangements fail to perform, we may be forced to enter into alternative arrangements to meet our normal business requirements. In that event, NW Holdings’ or NW Natural’s financial results could be adversely affected. Additionally, under most of NW Natural’s hedging arrangements, a downgrade of its senior unsecured long-term debt credit rating could allow its counterparties to require NW Natural to post cash, a letter of credit or other form of collateral, which would expose NW Natural to additional costs and may trigger significant increases in borrowing from its credit facilities or equity contribution needs from NW Holdings, if the credit rating downgrade is below investment grade. Further, based on current interpretations, each of NW Holdings, NW Natural and NWN Water is not considered a "swap dealer" or "major swap participant" in 2024, so we are exempt from certain requirements under the Dodd-Frank Act. If we are unable to claim this exemption, we could be subject to higher costs for our derivatives activities, and such higher costs could have a negative impact on NW Holdings’ and NW Natural’s operating costs and financial results.
GAS PRICE RISK. Higher natural gas commodity prices and volatility in the price of gas may adversely affect our NGD business, whereas lower gas price volatility may adversely affect NW Natural’s gas storage business, negatively affecting NW Holdings’ and NW Natural’s results of operations and cash flows.
The cost of natural gas is affected by a variety of factors, including weather, changes in demand, the level of production and availability of natural gas supplies, transportation constraints, availability and cost of pipeline capacity, federal, state and local energy and environmental policy, regulation and legislation, natural disasters and other catastrophic events, national and worldwide economic and political conditions, and the price and availability of alternative fuels. In recent years, we have experienced increased pricing and volatility in the current and forward gas markets. In addition, potential tariffs or trade restrictions could impact the price of natural gas that we import from Canada. At our gas businesses, the cost we pay for natural gas is generally passed through to customers through an annual purchased gas rate adjustment. If gas prices were to increase significantly and remain higher, it could raise the cost of energy to our customers, potentially causing those customers to conserve or switch to alternate sources of energy. Sustained significant price increases could also cause new home builders and commercial developers to select alternative energy sources. Decreases in the volume of gas we sell could reduce NW Holdings or NW Natural’s earnings, and a decline in customers could slow growth in future earnings. Additionally, notwithstanding NW Natural’s current rate structure, higher gas costs could result in increased pressure on the OPUC or the WUTC to seek other means to reduce NW Natural’s rates, which also could adversely affect NW Holdings’ and NW Natural’s results of operations and cash flows.
Temporary gas price increases can also adversely affect NW Holdings’ and NW Natural’s operating cash flows, liquidity and results of operations. In Oregon, a portion (10% or 20%) of any difference between the estimated average PGA gas cost in rates and the actual average gas cost incurred is recognized as current income or expense.
Temporary or sustained higher gas prices may also cause us to experience an increase in short-term debt and temporarily reduce liquidity because it pays suppliers for gas when it is purchased, which can be in advance of when these costs are recovered through rates. Significant increases in the price of gas can also slow collection efforts as customers experience increased difficulty in paying their higher energy bills, leading to higher than normal delinquent accounts receivable resulting in greater expense associated with collection efforts and increased bad debt expense.
INABILITY TO ACCESS CAPITAL MARKET RISK. NW Holdings’ or NW Natural’s inability to access capital, or significant increases in the cost of capital, could adversely affect NW Holdings’ or NW Natural’s financial condition and results of operations.
NW Holdings’ and NW Natural’s ability to obtain adequate and cost effective short-term and long-term financing depends on maintaining investment grade credit profiles, perceptions of our business in capital markets, and the existence of liquid and stable financial markets. NW Holdings relies on access to equity, debt, and bank markets to finance equity contributions to subsidiaries and other business requirements. NW Natural relies on access to capital and bank markets, including commercial paper and bond markets, to finance its operations, construction expenditures and other business requirements, and to refinance maturing debt that cannot be funded entirely by internal cash flows. Disruptions in capital markets, including but not limited to, pandemics, political unrest, inflationary pressures, recessionary pressures, or rising interest rates could adversely affect our ability to access short-term and long-term financing or refinance maturing indebtedness. Our access to funds under committed
credit facilities, which are currently provided by a number of banks, is dependent on the ability of the participating banks to meet their funding commitments. Those banks may not be able to meet their funding commitments if they experience shortages of capital and liquidity. Disruptions in the bank or capital financing markets as a result of economic uncertainty, changing or increased regulation of the financial sector, or failure of major financial institutions, or disruptions in credit markets, could adversely affect NW Holdings’ and NW Natural’s access to capital and negatively impact our ability to run our businesses, achieve NW Natural’s authorized rate of return, and make strategic investments.
Furthermore, recent trends toward investments that are perceived to be “green” or “sustainable” could shift capital away from, or increase the cost of capital for, our natural gas business. We believe our business is an important component of a lower carbon future and are striving to reduce emissions from our systems. Nevertheless, perceptions in the financial markets could differ or outpace our progress toward reducing emissions and result in a shift funding away from, or limit or restrict certain forms of funding for, natural gas businesses. Similarly, public policy developments impacting natural gas, including through local, state or federal laws or legislation or other regulation (including ballot initiatives, executive orders or regulatory codes) or litigation could impact our ability to access capital.
NW Natural is currently rated by S&P and Moody’s, and NW Holdings is currently rated by S&P. A negative change in their respective credit ratings, particularly below investment grade, could adversely affect our cost of borrowing and access to sources of liquidity and capital. Such a downgrade could further limit our access to borrowing under available credit lines. Additionally, downgrades in NW Natural’s current credit ratings below investment grade could cause additional delays in NW Natural's ability to access the capital markets while it seeks supplemental state regulatory approval, which could hamper its ability to access credit markets on a timely basis. NW Holdings' credit profile is largely supported by NW Natural’s credit ratings and any negative change in NW Natural’s credit ratings would likely negatively impact NW Holdings’ access to sources of liquidity and capital and cost of borrowing. A credit downgrade could also require additional support in the form of letters of credit, cash or other forms of collateral and otherwise adversely affect NW Holdings' or NW Natural’s financial condition and results of operations.
IMPAIRMENT OF LONG-LIVED ASSETS OR GOODWILL RISK. Impairments of the value of long-lived assets or goodwill could have a material effect on NW Holdings’ or NW Natural’s financial condition, or results of operations.
NW Holdings and NW Natural review the carrying value of long-lived assets other than goodwill whenever events or changes in circumstances indicate the carrying amount of the assets might not be recoverable. The determination of recoverability is based on the undiscounted net cash flows expected to result from the operation of such assets. Projected cash flows depend on the future operating costs and projected revenues associated with the asset.
We review the carrying value of goodwill annually or whenever events or changes in circumstances indicate that such carrying value may not be recoverable. A goodwill impairment analysis begins with a qualitative analysis of events and circumstances. If the qualitative assessment indicates that the carrying value may be at risk, we will perform a quantitative assessment and recognize a goodwill impairment for any amount in which the fair value of a reporting unit exceeds its fair value. NW Holdings' total goodwill was $183.8 million as of December 31, 2024 and $163.3 million as of December 31, 2023, which all related to water and wastewater acquisitions. There have been no impairments recognized for the water and wastewater acquisitions to date. Any impairment charge taken with respect to our long-lived assets or goodwill could be material and could have a material effect on NW Holdings’ or NW Natural’s financial condition and results of operations.
CUSTOMER CONSERVATION RISK. Customers’ conservation efforts may have a negative impact on NW Holdings’ and NW Natural’s revenues.
An increasing national focus on energy conservation, including improved building practices and appliance efficiencies may result in increased energy conservation by customers. This can decrease our sales of natural gas and adversely affect NW Holdings’ or NW Natural’s results of operations because revenues are collected mostly through volumetric rates, based on the amount of gas sold. In Oregon, NW Natural has a conservation tariff which is designed to recover lost utility margin due to declines in residential and small commercial customers’ consumption. However, NW Natural does not have a conservation tariff in Washington that provides it this margin protection on sales to customers in that state. Similar conservation risks exist for water utilities. Customers’ conservation efforts may have a negative impact on NW Holdings' and NW Natural’s financial condition, revenues and results of operations.
ECONOMIC RISK. Changes in the economy and in the financial markets may have a negative impact on our financial condition and results of operations.
If an economic slowdown occurs, our financial condition, results of operations, and cash flows could be adversely affected. Moreover, fluctuations and uncertainties in the economy make it challenging for us to accurately forecast and plan future business activities and to identify risks that may affect our business, financial condition, and operating results. Changes in economic activity in our markets and in global financial markets can result in lower demand for energy, increased incidence of customers’ inability to pay or delay in paying utility bills or increase in customer bankruptcies, less new housing construction or fewer conversions to natural gas, higher levels of residential foreclosures or vacancies, uncertainty regarding energy prices and the capital and commodity markets, increased credit risk and supply chain uncertainty. We are evaluating and monitoring current economic conditions, which include but are not limited to: inflation and interest rates, supply chain disruptions, and other
regulatory, physical or cyber related risks impacting our business. These and other macroeconomic conditions may adversely impact the markets in which we operate and could cause the local, national or global economy to enter a period of recession. We cannot predict the timing, strength, or duration of any future economic slowdown or recession. If the economy or the markets in which we operate decline from present levels, it may have an adverse effect on our business, financial condition, and results of operations.
WEATHER RISK. Warmer than average weather may have a negative impact on our revenues and results of operations.
We are exposed to weather risk in our natural gas businesses. A majority of NW Natural’s gas volume is driven by gas sales to space heating residential and small commercial customers during the winter heating season. Current NW Natural rates are based on an assumption of average weather. Warmer than average weather typically results in lower gas sales. Colder weather typically results in higher gas sales. Although the effects of warmer or colder weather on utility margin in Oregon are expected to be mitigated through the operation of NW Natural’s weather normalization mechanism, weather variations from normal could adversely affect utility margin because NW Natural may be required to purchase more or less gas at spot rates, which may be higher or lower than the rates assumed in its PGA. Additionally, extreme weather events, such as those that occurred in NW Natural’s service territory in February 2021 and January 2024 can result in the purchase of higher levels of gas at significantly higher spot rates. Also, a portion of NW Natural’s Oregon residential and commercial customers (usually less than 10%) have opted out of the weather normalization mechanism, and approximately 12% of its customers are located in Washington where it does not have a weather normalization mechanism. SiEnergy, our gas utility in Texas similarly maintains a weather normalization mechanism, however, this mechanism may not fully mitigate the impact of warmer or colder than expected weather in Texas. These effects could have an adverse effect on NW Holdings’ and NW Natural’s financial condition, results of operations and cash flows.
Water Business Risks
WATER SECTOR BUSINESS. NW Holdings' water, wastewater and water services businesses are subject to a number of risks in addition to the risks described above.
Although the water businesses are not currently expected to materially contribute to the results of operations of NW Holdings, these businesses are subject to risks, in addition to those described above, including:
•contamination of water supplies, including water provided to customers with naturally occurring or human-made substances or other hazardous materials, or disruptions to water treatment processes;
•interruptions in water supplies and service, weather conditions, natural disasters and droughts;
•insufficient water supplies, limitations on or disputes with respect to water rights or supplies, or the inability to secure water rights or supplies at a reasonable cost;
•disruptions to the wastewater collection and treatment process, including spills, overflows or system failures;
•wastewater discharges by third parties that contain unanticipated levels of chemical or other pollutants;
•reliance on third parties for water supplies and transportation of such water supplies;
•the ability to attract and retain customers to our water services business and competition for customers’ business;
•conservation efforts by customers;
•regulatory and legal requirements, including environmental, health and safety laws and regulations;
•operational risks, including customer and employee safety; and
•the outcome of rate cases and other regulatory proceedings.
Significant losses, liabilities or impairments arising from these businesses may adversely affect NW Holdings' financial position or results of operations.
INVESTMENT RISK. NW Holdings’ expectations with respect to the financial results of its investments in water, wastewater and water services operations are based on various assumptions and beliefs that may not prove accurate, resulting in failures or delays in achieving expected returns or performance.
NW Holdings’ expansion into the water sector is an important component of its growth strategy. Although NW Holdings expects its water and wastewater utility operations and water services businesses will result in various benefits, including expanding customer bases, providing investment opportunities through infrastructure development and enhancing regulatory relationships within the local communities served, NW Holdings may not be able to realize these or other benefits. Achieving the anticipated benefits is subject to a number of uncertainties, including whether the businesses acquired can be operated in the manner intended and whether costs to finance the acquisitions and investments will be consistent with expectations, as well as whether investments in the water sector can reach scale in a reasonable period of time. Events outside of our control, including but not limited to regulatory changes or developments, could adversely affect our ability to realize the anticipated benefits from building NW Holdings’ water platform. The integration of newly acquired water, wastewater or water services businesses, particularly over noncontiguous geographic regions, may be unpredictable, subject to delays or changed circumstances, and such businesses may not perform in accordance with our expectations. In addition, anticipated costs, level of management’s attention and internal resources to achieve the integration of or operate the acquired businesses may differ significantly from our current estimates resulting in failures or delays in achieving expected returns or performance. We have previously acquired, and from time to time may make further investments in unregulated businesses on the water platform, including wastewater and water services businesses, which may result in additional uncertainty or volatility of earnings from these businesses. If NW Holdings'
expectations regarding the financial results of its investments in water, wastewater or water services operations prove to be inaccurate, it may adversely affect NW Holdings' financial position or results of operations.
Non-Regulated RNG Risks
INVESTMENT RISK. NW Holdings’ expectations with respect to the financial results of its investments in non-regulated RNG investments are based on various assumptions and beliefs that may not prove accurate, resulting in failures or delays in achieving expected returns.
NW Holdings’ expansion into the non-regulated RNG business is an important component of its growth strategy. Although NW Holdings expects this expansion will result in various benefits, including providing renewable fuels to support decarbonization in the utility, commercial, industrial and transportation sectors, NW Holdings may not be able to realize these or other benefits. Achieving the anticipated benefits is subject to a number of uncertainties, including whether the investments can be made at an expected scale, whether the investments can be monetized in the manner intended, and whether costs to finance the investments will be consistent with expectations. Events outside of our control, including but not limited to market or regulatory changes or developments, could adversely affect our ability to realize the anticipated benefits from building NW Holdings’ non-regulated RNG platform. The establishment and growth of a non-regulated RNG business may be unpredictable, subject to uncertainties or changed circumstances, and such business may not perform in accordance with our expectations. In addition, anticipated costs, level of management’s attention and internal resources to achieve the integration of the acquired investments may differ significantly from our current estimates resulting in failures or delays in achieving expected returns or performance. As part of our business model, we may purchase RNG from third parties in a variety of structures, including on a volumes-produced basis. Conversely, we may sell RNG in a variety of structures, including on a fixed-volume basis. This model could result in a mismatch between our purchased RNG portfolio and RNG volumes we have contracted to sell at any one time, which could result in our obligation to procure additional RNG at then-market prices or to pay damages to satisfy RNG sales contracts to which we are a party, which amounts could be significant. For example, the RNG purchase contract between Ohio Renewables and a subsidiary of EDL is on a volumes-produced basis, whereas Ohio Renewables’ contract for the sale of RNG from 2025 through 2042 is a fixed-volume contract. We could additionally experience technological challenges; ineffective scalability or inability to achieve production volumes consistent with our expectations and marketing arrangements; construction delays or cost overruns; disputes with third party business partners; risks related to markets for RNG and its associated attributes (including changes in market regulation, behavior, or prices); the inability to receive expected tax or regulatory treatment; unsuccessful business models; or unexpected operating costs. If NW Holdings’ expectations regarding the financial results of its investments in non-regulated RNG prove to be inaccurate, it may adversely affect NW Holdings’ financial position or results of operations.
RENEWABLES BUSINESS RISK. NW Natural Renewables is an unregulated subsidiary of NW Holdings established to pursue unregulated renewable natural gas activities. These activities are subject to a number of risks in addition to the risks described above.
Our Renewables business is subject to risks, in addition to those described above, including:
•unpredictable production levels or performance or gas quality below expected levels, which may impact our ability to accept or deliver RNG under our contractual agreements;
•construction risks or delays, including due to inclement weather, supply chain or labor disruptions or otherwise;
•cost overruns and the need to commit more capital than initially budgeted as a result of environmental, construction, technological or other complications;
•weather conditions;
•changes in energy commodity prices, including pricing of, and volatility in markets for, RNG and its associated attributes;
•equipment failure, difficulties or delays in repairing or replacing equipment, technical difficulties or otherwise higher than expected operating costs;
•regulatory, policy, and legal requirements, including environmental, health and safety laws and regulations or regulations that may impact the value of RNG and its associated attributes or our ability to deliver RNG in the manner contemplated under our contractual arrangements;
•changes to laws or policies that may reduce demand for, or desirability of, RNG or its associated attributes;
•reliance on third parties, including for pipeline interconnection and for a sufficient supply of waste for conversion to RNG;
•catastrophic events such as fires, explosions, earthquakes, droughts, acts of terrorism and other force majeure events that may impact the Renewables business, its customers, suppliers, or other business partners; and
•failures or delays in obtaining necessary land rights, permits, approvals or other consents required to construct and operate projects.
Significant losses, liabilities or impairments arising from these businesses may adversely affect NW Holdings' financial position or results of operations.
ITEM 1B. UNRESOLVED STAFF COMMENTS
We have no unresolved staff comments.
ITEM 1C. CYBERSECURITY
Processes of Addressing Cybersecurity Threats
Cybersecurity is critical to our business. As an energy infrastructure company, we face a variety of cybersecurity threats that range from attacks common to most industries, such as ransomware and denial-of-service, to attacks from more advanced and persistent, highly organized adversaries, including nation state actors, that target critical infrastructure sectors. We recognize the critical importance of maintaining the safety and security of our systems and data and have a holistic process for overseeing and managing cybersecurity and related risks. The process is supported by management and overseen by our Board of Directors.
One of the tools used by management and our Board of Directors in managing business risks is an annual enterprise risk management (ERM) assessment to identify and manage key existing and emerging risks our company faces. Our ERM process is designed to identify significant risks relevant to the company and assess the characteristics and circumstances of the risks to identify both the potential impacts to our company of a particular risk and the velocity with which the risk may manifest. Cybersecurity is among the risks identified in our ERM assessment and has been embedded in the Company’s operating procedures, internal controls and information systems.
In addition to our overall ERM process, we have developed and implemented a cybersecurity risk management program and processes intended to detect, assess, manage, and develop resiliency against material risks from cybersecurity threats. Our cybersecurity program utilizes a risk-based approach and includes written cybersecurity and information technology processes and procedures, including a cybersecurity incident response plan that involves procedures for responding to cybersecurity incidents. We design and assess our program informed by various cybersecurity frameworks, such as the National Institute of Standards and Technology (NIST) and leverage a widely-adopted risk assessment model to identify, measure and prioritize cybersecurity and technology risks. The goal of our program is to prevent, identify, escalate, investigate, resolve and recover from identified incidents and security incidents in a timely manner.
Our cybersecurity program also incorporates intelligence sharing capabilities about emerging threats within the utility industry and other industries through collaboration with peer companies and specialized consultants and advisors, public-private partnerships with government intelligence agencies, including the FBI, CISA, and the Department of Energy Office of Cybersecurity, Energy Security and Emergency Response, and geopolitical briefings. We also leverage third-party benchmarking, the results from regular internal and third-party audits, technology partner resources, threat intelligence feeds, and other similar resources to inform our cybersecurity processes and allocate resources.
Beginning in May 2021, the Department of Homeland Security’s (DHS) and the Transportation Security Administration (TSA) released two directives, with several updates, applicable to certain owners and operators of pipeline facilities, including NW Natural. These directives cumulatively require owners and operators to implement cybersecurity incident reporting to the DHS, designate two cybersecurity coordinators, and perform a gap assessment of current entity cybersecurity practices against certain voluntary TSA security guidelines and report relevant results and proposed mitigation to applicable DHS agencies; implement a significant number of specified cyber security controls and processes; and clarifying Operational Technology (OT) scope and providing a risk- and outcome-based framework. We made significant additional and accelerated investments in cybersecurity in response to the TSA directives. In November 2024, the TSA proposed regulations with the aim of making the security directives permanent by incorporating them into the US Code of Federal Regulations.
Our cybersecurity program has several fundamental tenants, including security governance, cybersecurity risk management, compliance, defensibility, zero-trust architecture and cloud security. We utilize multilayered defenses and continuous monitoring with data analytics to detect anomalies and search for cyber threats in our system.
Key components of our cybersecurity risk management program include:
•risk assessments designed to help identify cybersecurity risks to our critical systems, information, services, and our broader technology environment;
•the use of external service providers with specific expertise, where appropriate, to assess, test or otherwise assist with aspects of our security processes;
•cybersecurity awareness training of our employees, incident response personnel and senior management, as well as periodic experiential learning through “phishing simulations”;
•segmentation of, and back-ups for, certain of our sensitive systems and data;
•third-party cyber risk management process for vendors including, among other things, a security assessment, contracting program, and ongoing monitoring for vendors based on their risk profile; and
•physical security around our sensitive infrastructure and cybersystems.
In accordance with our program and processes, we regularly assess risks from cybersecurity and technology threats and monitor our information systems for potential vulnerabilities. We conduct regular reviews and tests of our information security program and also utilize audits by our internal audit team and third-party consultants, table-top exercises, penetration and vulnerability testing, data recovery testing, simulations, and other exercises to evaluate the effectiveness of our information security program
and improve our security measures and planning. We are continuously working to evolve our oversight processes to mature how we identify and manage cybersecurity risks, and we perform periodic maturity assessments to measure our progress.
As a regulated energy infrastructure company, for decades we have used an incident command system (ICS) as a standardized approach to the command, control and coordination of a variety of emergency situations. In the event of emergencies, including cybersecurity events, we stand up a cross-functional Incident Command Team (ICT) to respond to the emergency. We exercise and train the ICT for a variety of emergencies, including cyber events on a regular basis.
At this time, we have not identified any risks from known previous cybersecurity incidents, that have materially affected or are reasonably likely to materially affect us, including our operations, business strategy, results of operations or financial condition. With a majority of our business in energy and infrastructure, we face sophisticated and rapidly evolving attempts to overcome our security measures and protections. The occurrence of both intentional and unintentional incidents could occur in the future. We face certain ongoing risks from cybersecurity threats that, if realized, are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial condition. See Item 1A, "Risk Factors” above for additional information on risks related to our business, including for example risks related to cyber attacks, information and system breaches, technology disruptions and failures, and our reliance on technology.
Cybersecurity Governance
Our Board considers cybersecurity risk as part of its risk oversight function and has delegated oversight of cybersecurity and other information technology risks to the Audit Committee. The Audit Committee oversees management’s implementation of the cybersecurity risk management program.
The Audit Committee receives regular reports from management on our cybersecurity risks. Additionally, management updates the Audit Committee as necessary, regarding any cybersecurity incidents. The Audit Committee reports to the full Board regarding the Audit Committee’s areas of oversight, including those related to cybersecurity. The full Board also receives briefings from management on our cybersecurity risk management program periodically. Additionally, our Board receives presentations on cybersecurity topics from our IT management team or external experts as part of the Board’s ongoing education.
Our management team, including our Cybersecurity management team, has primary responsibility for our overall cybersecurity risk management program, and supervises both our internal cybersecurity personnel and our retained external cybersecurity consultants. Our Cybersecurity management team is led by Brian Fellon, our Vice President, Chief Information Officer and Chief Information Security Officer (VP, CIO and CISO). Mr. Fellon joined NW Natural and was appointed to his role by the Board of Directors in September 2024. Mr. Fellon reports to our Chief Financial Officer. He has 28 years of experience in information technology. Prior to joining NW Natural, Mr. Fellon served as Director of Information Technology at Puget Sound Energy in Bellevue, Washington from 2016 to September 2024, where he was responsible for applications services, artificial intelligence and data.
Mr. Fellon is supported by our Director of Cybersecurity and Compliance, and his team. Collectively our team has certifications from various organizations such as American Society for Industrial Security, AXELOS, Cloud Security Alliance, Information Systems Audit and Control Association, International Information System Security Certification Consortium and SANS Institute.
Our cybersecurity and compliance team regularly collects data on cybersecurity threats and risk areas, monitors our systems, and conducts testing to assess our processes and procedures and the threat landscape. Our VP, CIO and CISO receives regular updates on cybersecurity matters, results of mitigation efforts and cybersecurity incident response and remediation.
In the event of an incident, we intend to utilize our ICT and follow our detailed incident program and processes, which outlines the steps to be followed from incident detection to mitigation, recovery and notification, including notifying relevant functional areas, as well as senior leadership and the Board, as appropriate.

NON-GAAP FINANCIAL MEASURES. 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 in this section to earnings per share (EPS) are on the basis of diluted shares. We use such non-GAAP financial measures to analyze our financial performance because we believe they provide useful information to our investors, analysts, 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 below.

| 2024 | | 2023 | | 2022 |
| In millions | Amount | | Amount | | Amount |
| Consolidated net income | $ | 89.0 | | | $ | 104.7 | | | $ | 91.6 | |
| Natural gas distribution margin | 601.3 | | | 575.0 | | | 505.9 | |
2024 COMPARED TO 2023. Consolidated net income decreased $15.7 million at NW Natural primarily due to the following factors:
•$18.2 million decrease in other income, net primarily due to higher pension costs, lower interest income from invested cash, lower regulatory interest income and a decline in the equity portion of Allowance for Funds Used During Construction (AFUDC);
•$13.7 million decrease due to the disallowance of undepreciated line extension costs as ordered in the 2024 Oregon general rate case;
•$10.1 million increase in depreciation expense from continued capital investments in our system for safety and reliability;
•$2.7 million increase in interest expense, net primarily due to higher short and long-term debt balances; and
•$2.0 million increase in general taxes primarily driven by higher regulatory commission fees; partially offset by
•$26.3 million increase in NGD segment margin driven by new rates on November 1, 2024 for Oregon, the amortization of deferred balances and customer growth; partially offset by lower usage from warmer comparative weather for customers not covered under the weather normalization mechanism;
•$3.1 million increase in gas storage revenue; and
•$1.4 million decrease in operations and maintenance expenses (excluding the regulatory disallowance) due to lower contract labor costs and lower bad debt expense, partially offset by higher amortization expense related to cloud computing arrangements.
Consolidated net income decreased $15.0 million at NW Holdings primarily due to the following factors:
•$15.7 million decrease in consolidated net income at NW Natural as discussed above; partially offset by
•$0.7 million increase in other net income primarily reflecting a $4.4 million increase in net income from water and wastewater subsidiaries, partially offset by $2.3 million of acquisition costs related to SiEnergy and higher interest expense at the holding company.
2023 COMPARED TO 2022. Consolidated net income increased $13.2 million at NW Natural primarily due to the following factors:
•$69.1 million increase in NGD segment margin driven by new rates in Oregon and Washington, actual gas prices that were lower than what was estimated in the 2022-2023 PGA, amortization of deferred balances (which is mostly offset in operations and maintenance expenses and interest expense), and customer growth; and
•$15.8 million increase in other income, net primarily due to interest income from invested cash and the equity portion of AFUDC, and lower pension costs; partially offset by
•$39.8 million increase in operations and maintenance expenses due to higher payroll costs, higher contract labor, the amortization of deferred balances (which is mostly offset in revenues), information technology costs and amortization expense related to cloud computing arrangements;
•$14.3 million increase in interest expense, net primarily due to higher long-term debt balances;
•$6.5 million increase in depreciation expense due to additional capital investments;
•$4.8 million increase in general taxes primarily driven by higher property and payroll taxes; and
•$4.6 million increase in income tax expense due to higher pre-tax income.
Consolidated net income increased $7.6 million at NW Holdings primarily due to the following factors:
•$13.2 million increase in consolidated net income at NW Natural as discussed above; partially offset by
•$5.6 million decrease in other net income primarily reflecting higher interest expense at the holding and water companies.
CURRENT ECONOMIC AND POLITICAL CONDITIONS. We continuously review and monitor current economic conditions, which include but are not limited to: inflation and interest rates, supply chain disruptions, and other regulatory, physical or cyber related risks impacting our business. Over the prior two years, we experienced higher material and labor costs across our businesses resulting from high levels of inflation. In 2024, inflation has come down from these prior year highs and we have started to experience more traditional price impacts in 2024. Lead times on materials have returned to normal levels in 2024 for most inventory items. We continue to look for opportunities through advanced planning to ensure inventory levels are appropriately maintained. With the improved lead times we have been able to also increase inventory turnover and reduce the amounts of inventory needed on hand in 2024.
NW Holdings and NW Natural monitor interest rates and financing options for all of its businesses. While short-term rates increased considerably starting in 2022 and through 2023, the U.S. Federal Reserve started reducing short-term rates in the second half of 2024 from the highs experienced in 2023. Long-term interest rates also increased in 2022 from historically low levels, however long-term rates have since stabilized and maintained a consistent level over the past two years and are down from their highest levels in 2023. NW Natural generally recovers interest expense on its long-term debt through its authorized cost of capital. Certain working capital items, such as the cost of gas, are deferred and accrue interest in Oregon and Washington. Additionally, short-term debt is incorporated in the capital structure in Washington. NW Natural Water's regulated water and wastewater utilities generally recover interest expense from long-term debt through their respective authorized cost of capital.
We continue to monitor a wide range of new policies, executive orders, rules, initiatives and other changes to fiscal, tax, regulation, environmental, climate and other federal policies that may impact NW Natural and NW Holdings under the new U.S. Governmental Administration. Similarly, we could face significant legislative, regulatory and other policy changes at the state level or in the local jurisdictions in which we operate.
See the discussion in "Results of Operations", "Regulatory Matters" and "Financial Condition" below for additional detail regarding all significant activity that occurred during 2024.

RESULTS OF OPERATIONS
Regulatory Matters
Regulation and Rates
NATURAL GAS DISTRIBUTION. NW Natural's natural gas distribution business is subject to regulation by the OPUC and WUTC with respect to, among other matters, rates and terms of service, systems of accounts, and issuances of securities by NW Natural. In 2024, approximately 88% of NGD customers were located in Oregon, with the remaining 12% in Washington. Earnings and cash flows from natural gas distribution operations are largely determined by rates set in general rate cases and other proceedings in Oregon and Washington. They are also affected by weather, the local economies in Oregon and Washington, the pace of customer growth in the residential, commercial, and industrial markets, federal, state and local energy, policy, customer preferences and NW Natural's ability to remain price competitive, control expenses, and obtain reasonable and timely regulatory recovery of its natural gas distribution-related costs, including operating expenses and investment costs in plant and other regulatory assets. See "Most Recent Completed Rate Cases" below.
MIST INTERSTATE GAS STORAGE. NW Natural's interstate storage activity at Mist is subject to regulation by the OPUC, WUTC, and the Federal Energy Regulatory Commission (FERC) with respect to, among other matters, rates and terms of service. The OPUC also regulates intrastate storage services at Mist, while FERC regulates interstate storage services at Mist. The FERC uses a maximum cost of service model which allows for gas storage prices to be set at or below the cost of service as approved by each agency in our last regulatory filing. The OPUC Schedule 80 rates are tied to the FERC rates, and are updated whenever NW Natural modifies FERC maximum rates. See "Most Recent Completed Rate Cases" below.
OTHER. The wholly-owned regulated water businesses of NWN Water, a wholly-owned subsidiary of NW Holdings, are subject to regulation by the utility commissions in the states in which they are located, which currently includes Oregon, Washington, Arizona, Idaho, and Texas. The wholly-owned regulated wastewater businesses of NWN Water are subject to regulation by the utility commissions in the states in which they are located, which currently includes Texas and Arizona.
Most Recent Completed Rate Cases
OREGON. On December 29, 2023, NW Natural filed a request for a general rate case (Rate Case) with the OPUC. On October 25, 2024, the OPUC issued an order approving two stipulations and resolving the remaining open items in the Rate Case. The final order provided for a total revenue requirement increase of $93.3 million over revenues from existing rates, which includes $9.6 million related to an updated depreciation study. The revenue requirement is based on the following assumptions:
•Capital structure of 50% common equity and 50% long-term debt;
•Return on equity of 9.4%;
•Cost of capital of 7.056%;
•Cost of long-term debt of 4.712%; and
•Average rate base of $2.09 billion or an increase of $334 million since the last rate case.
In addition to the above, the OPUC ordered the phase out of NW Natural’s line extension allowance by November 1, 2027. Additionally, the OPUC ordered a downward adjustment to rate base of $13.7 million of undepreciated line extension costs, which resulted in a non-cash, pre-tax charge of $13.7 million in the fourth quarter of 2024. In December 2024, NW Natural filed an appeal with the Oregon Court of Appeals, challenging the determination and the authority of the OPUC to take these actions.
New rates authorized by the OPUC order were effective November 1, 2024.
On October 24, 2022, the OPUC issued an order for rates effective November 1, 2022, which authorized a return on equity (ROE) of 9.4%, a cost of capital of 6.836%, and a capital structure of 50% common equity and 50% long-term debt. The OPUC further adopted an automatic adjustment clause that allows for NW Natural’s RNG project costs to be added to rates annually on November 1st.
From November 1, 2020 through October 31, 2022, the OPUC authorized rates to customers based on an ROE of 9.4% and a cost of capital of 6.965% with a capital structure of 50% common equity and 50% long-term debt. The OPUC also authorized NW Natural to recover the expense associated with the Oregon Corporate Activity Tax (CAT) as a component of base rates.
WASHINGTON. On October 21, 2021, the WUTC issued an order concluding NW Natural's general rate case filed in December 2020 (WUTC Order). The WUTC Order provides for an annual revenue requirement increase over two years, consisting of a 6.4% or $5.0 million increase in the first year beginning November 1, 2021 (Year One), and up to a 3.5% or $3.0 million increase in the second year beginning November 1, 2022 (Year Two). The increase is based on the following assumptions:
•Cost of capital of 6.814%; and
•Average rate base of $194.7 million, an increase of $20.9 million since the last rate case for capital expenditures already expended at the time of filing, with an additional expected $31.2 million increase in Year One, and an additional expected $21.4 million increase in Year Two, with the increases in Year One and Year Two relating to expected capital expenditures in those years.
The WUTC Order does not specify the underlying inputs to the cost of capital, including capital structure and return on equity. New rates authorized by the WUTC Order were effective November 1, 2021. In September 2023, NW Natural received a letter of compliance from the WUTC acknowledging that the Year Two rates are no longer subject to review and refund.
FERC. NW Natural is required under its Mist interstate storage certificate authority and rate approval orders to file every five years either a petition for rate approval or a cost and revenue study to change or justify maintaining the existing rates for its interstate storage services. NW Natural filed a rate petition with the FERC in August 2023 and the revised rates were effective beginning September 1, 2023.
NW Natural continuously evaluates the need for rate cases in its jurisdictions.
Regulatory Proceeding Updates
2025 OREGON RATE CASE. On December 30, 2024, NW Natural filed a request for a general rate increase with the OPUC. The filing includes a requested $59.4 million annual revenue requirement increase, or an approximate 5.79% increase over current customer rates. The request is based upon the following assumptions or requests:
•Capital structure of 48% long-term debt and 52% equity;
•Return on equity of 10.4%;
•Cost of capital of 7.658%; and
•Average rate base of $2.29 billion.
The filing includes approximately $10 million related to an updated depreciation study and an increase in average rate base of $204 million compared to the last rate case for several long-planned investments by NW Natural including the following:
•Supporting reinforcement, safety and reliability of NW Natural's distribution systems and operating facilities;
•Upgrading technology to, among other things, further modernize NW Natural’s information technology infrastructure, and enhance cybersecurity protections, and
•Investing in components of NW Natural’s Mist gas storage facility, which supports service during winter heating months.
NW Natural’s filing will be reviewed by the OPUC and other stakeholders. The process is anticipated to take up to 10 months with new rates expected to take effect November 1, 2025.

| ** The WUTC Order does not specify the underlying inputs to the cost of capital, including capital structure and return on equity. |
Annually, or more often if circumstances warrant, NW Natural reviews all regulatory assets for recoverability. If NW Natural should determine all or a portion of these regulatory assets no longer meet the criteria for continued application of regulatory accounting, then NW Natural would be required to write-off the net unrecoverable balances against earnings in the period such a determination was made.
PURCHASED GAS ADJUSTMENT. Rate changes are established for NW Natural each year under purchased gas adjustment (PGA) mechanisms in Oregon and Washington to reflect changes in the expected cost of natural gas commodity purchases. The PGA filings include costs for gas purchases, gas commodity derivative contracts, gas storage costs, gas reserves costs, pipeline demand costs, renewable natural gas and its environmental attributes, including renewable thermal certificates, and temporary rate adjustments, which amortize balances of deferred regulatory accounts.
In September 2024, NW Natural filed its annual PGAs and received OPUC and WUTC approval in October 2024. PGA rate changes were effective November 1, 2024. Rates may vary between states due to different rate structures, rate mechanisms and hedging policies.
Each year, NW Natural hedges gas prices on a portion of NW Natural's annual sales requirement based on normal weather, including both physical and financial hedges. NW Natural entered the 2024-25 gas year with total forecasted sales volume hedged at approximately 80%, including 64% in financial hedges and 16% in physical gas supplies. The total hedged was approximately 86% in Oregon and 32% in Washington.
For the subsequent two gas years, NW Natural was hedged in total between 13% and 31% for annual requirements, which consists of between 14% and 34% in Oregon and 0% and 10% in Washington. Hedge levels are subject to change based on actual load volumes, which depend to a certain extent on weather, economic conditions, and gas reserve production. Also, gas storage inventory levels may increase or decrease with storage expansion, changes in storage contracts with third parties,
variations in the heat content of the gas, and/or storage recall by NW Natural. Gas purchases and hedges entered into for the upcoming PGA year will be included in the Company’s PGA filings in Oregon and Washington.
Under the current PGA mechanism in Oregon, there is an incentive sharing provision whereby NW Natural is required to select each year an 80% deferral or a 90% deferral of higher or lower actual gas costs compared to estimated PGA prices, such that the impact on NW Natural's current earnings from the incentive sharing is either 20% or 10% of the difference between actual and estimated gas costs, respectively. For the 2024-25 and 2023-24 gas years, NW Natural selected the 90% deferral option. Under the Washington PGA mechanism, NW Natural defers 100% of the higher or lower actual gas costs, and those gas cost differences are passed on to customers through the annual PGA rate adjustment.
As of May 1, 2024, 0.2 million therms per day of deliverability and 1.15 Bcf of associated non-utility Mist gas storage capacity was recalled to serve core customers. Customer rate increases related to this recall began on November 1, 2024.
CLIMATE COMMITMENT ACT. Washington has enacted the Climate Commitment Act (CCA), which establishes a comprehensive program that includes an overall limit for GHG emissions from major sources in the state that declines yearly. The program began January 1, 2023. In December 2024, the WUTC re-authorized a CCA cost recovery mechanism with a rate effective date of January 1, 2025. Under this mechanism, NW Natural recovers CCA costs and will defer any difference between forecasted and actual costs in the following year. Additionally, under the approved tariff, proceeds from the sale of allowances, which is required under the CCA, would be used to offset CCA compliance costs for low-income customers. Any remaining proceeds would benefit other customers through fixed bill credits or use in other carbon reduction programs.
Additionally in December 2023, the WUTC approved a request to modify NW Natural's CCA deferral to allow for the recovery of interest from customers based on the actual cash paid for purchases of allowances, less proceeds received from the sale of allowances.
EARNINGS TEST REVIEW. NW Natural is subject to an annual earnings review in Oregon to determine if the NGD business is earning above its authorized ROE threshold. If NGD business earnings exceed a specific ROE level, then 33% of the amount above that level is required to be deferred or refunded to customers. Under this provision, if NW Natural selects the 80% deferral gas cost option, then NW Natural retains all earnings up to 150 basis points above the currently authorized ROE. If NW Natural selects the 90% deferral option, then it retains all earnings up to 100 basis points above the currently authorized ROE. For the 2023-24 and 2024-25 gas years, NW Natural selected the 90% deferral option. The ROE threshold is subject to adjustment annually based on movements in long-term interest rates. For calendar years 2022, 2023, and 2024, the ROE threshold was 10.40% in all periods. There were no refunds required for 2022 and 2023. NW Natural does not expect a refund for 2024 based on results, and anticipates filing its 2024 earnings test in May 2025.
GAS RESERVES. In 2011, the OPUC approved the Encana gas reserves transaction to provide long-term gas price protection for NGD business customers and determined costs under the agreement would be recovered on an ongoing basis through the annual PGA mechanism. Gas produced from NW Natural's interests is sold at then prevailing market prices, and revenues from such sales, net of associated operating and production costs and amortization, are included in cost of gas. The cost of gas, including a carrying cost for the rate base investment made under the original agreement, is included in NW Natural's annual Oregon PGA filing, which allows NW Natural to recover these costs through customer rates. The net investment under the original agreement earns a rate of return.
In 2014, NW Natural amended the original gas reserves agreement in response to Encana's sale of its interest in the Jonah field located in Wyoming to Jonah Energy. Under the amended agreement with Jonah Energy, NW Natural has the option to invest in additional wells on a well-by-well basis with drilling costs and resulting gas volumes shared at the amended proportionate working interest for each well in which NW Natural invests. Volumes produced from the additional wells drilled after the amended agreement are included in NW Natural's Oregon PGA at a fixed rate of $0.4725 per therm. NW Natural has not participated in additional wells since 2014.
DECOUPLING. In Oregon, NW Natural has a decoupling mechanism that covers residential and some commercial sales customers. Decoupling is intended to break the link between revenue and the quantity of gas consumed by customers, removing any financial incentive to discourage customers’ efforts to conserve energy. This mechanism employs a use-per-customer decoupling calculation, which adjusts margin revenues to account for the difference between actual and expected customer volumes. The margin adjustment resulting from differences between actual and expected volumes under the decoupling component is recorded to a deferral account, which is included in the annual PGA filing. The 2024 Oregon general rate case reset the Oregon decoupling baseline usage per customer.
WARM. In Oregon, NW Natural has an approved weather normalization mechanism (WARM), which is applied to residential and small commercial customer bills. This mechanism is designed to help stabilize the collection of fixed costs by adjusting residential and small commercial customer billings based on temperature variances from average weather, with rate decreases when the weather is colder than average and rate increases when the weather is warmer than average. The mechanism is applied to bills from December through mid-May of each heating season. The mechanism adjusts the margin component of customers’ rates to reflect average weather, which uses the 25-year average temperature for each day of the billing period. Daily average temperatures and 25-year average temperatures are based on a set point temperature of 59 degrees Fahrenheit for
residential customers and 58 degrees Fahrenheit for commercial customers. The collections of any unbilled WARM amounts due to tariff caps and floors are deferred and earn a carrying charge until collected, or returned, in the PGA the following year. Residential and small commercial customers in Oregon are allowed to opt out of the weather normalization mechanism, and as of December 31, 2024, 7% of total eligible customers had opted out. NW Natural does not have a weather normalization mechanism approved for Washington customers, which account for about 12% of total customers. See "Business Segment—Natural Gas Distribution" below.
INDUSTRIAL TARIFFS. The OPUC and WUTC have approved tariffs covering NGD service to major industrial customers, which are intended to give NW Natural certainty in the level of gas supplies needed to serve this customer group. The approved terms include, among other things, an annual election period, special pricing provisions for out-of-cycle changes, and a requirement that industrial customers complete the term of their service election under NW Natural's annual PGA tariff.
ENVIRONMENTAL COST DEFERRAL AND RECOVERY. NW Natural has authorizations in Oregon and Washington to defer costs related to remediation of properties that are owned or were previously owned by NW Natural. In Oregon, a Site Remediation and Recovery Mechanism (SRRM) is currently in place to recover prudently incurred costs allocable to Oregon customers, subject to an earnings test. Effective beginning November 1, 2019, the WUTC authorized an Environmental Cost Recovery Mechanism (ECRM) for recovery of prudently incurred costs allocable to Washington customers.
Oregon SRRM
Under the Oregon SRRM collection process, there are three types of deferred environmental remediation expense:
•Pre-review - This class of costs represents remediation spend that has not yet been deemed prudent by the OPUC. Carrying costs on these remediation expenses are recorded at NW Natural's authorized cost of capital. NW Natural anticipates the prudence review for annual costs and approval of the earnings test prescribed by the OPUC to occur by the third quarter of the following year.
•Post-review - This class of costs represents remediation spend that has been deemed prudent and allowed after applying the earnings test, but is not yet included in amortization. NW Natural earns a carrying cost on these amounts at a rate equal to the five-year treasury rate plus 100 basis points.
•Amortization - This class of costs represents amounts included in current customer rates for collection and is calculated as one-fifth of the post-review deferred balance. NW Natural earns a carrying cost equal to the amortization rate determined annually by the OPUC, which approximates a short-term borrowing rate. NW Natural included $8.8 million and $9.6 million of deferred remediation expense approved by the OPUC for collection during the 2024-25 and 2023-24 PGA years, respectively.
In addition, the SRRM also provides for the annual collection of $5.0 million from Oregon customers through a tariff rider. As it collects amounts from customers, NW Natural recognizes these collections as revenue net of any earnings test adjustments and separately amortizes an equal and offsetting amount of the deferred regulatory asset balance through the environmental remediation operating expense line shown separately in the operating expenses section of the Consolidated Statements of Comprehensive Income (Loss). See Note 17 for more information on our environmental matters.
The SRRM earnings test is an annual review of adjusted NGD ROE compared to authorized NGD ROE. To apply the earnings test NW Natural must first determine what if any costs are subject to the test through the following calculation:
| | |
| Annual spend |
| Less: $5.0 million base rate rider |
Prior year carry-over(1) |
| $5.0 million insurance + interest on insurance |
| Total deferred annual spend subject to earnings test |
| Less: over-earnings adjustment, if any |
Add: deferred interest on annual spend(2) |
| Total amount transferred to post-review |
(1) Prior year carry-over results when the prior year amount transferred to post-review is negative. The negative amount is carried over to offset annual spend in the following year.
(2) Deferred interest is added to annual spend to the extent the spend is recoverable.
To the extent the NGD business earns at or below its authorized ROE as defined in the SRRM, the total amount transferred to post-review is recoverable through the SRRM. To the extent more than authorized ROE is earned in a year, the amount transferred to post-review would be reduced by those earnings that exceed its authorized ROE. For 2024, NW Natural has performed this test, which is anticipated to be submitted to the OPUC in May 2025. No earnings test adjustment is expected for 2024.
Washington ECRM
The ECRM established by the WUTC order effective November 1, 2019 permits NW Natural’s recovery of environmental remediation expenses allocable to Washington customers. These expenses represent 3.32% of costs associated with
remediation of sites that historically served both Oregon and Washington customers. The order allows for recovery of past deferred and future prudently incurred remediation costs allocable to Washington through application of insurance proceeds and collections from customers. Prudently incurred costs that were deferred from the initial deferral authorization in February 2011 through June 2019 were fully offset with insurance proceeds, with any remaining insurance proceeds to be amortized over a 10.5 year period. On an annual basis, NW Natural will file for a prudence determination and a request to recover remediation expenditures in excess of insurance amortizations in the following year's customer rates. After insurance proceeds are fully amortized, if in a particular year the request to collect deferred amounts exceeds one percent of Washington normalized revenues, then the excess will be collected over three years with interest.
INTERSTATE STORAGE AND ASSET MANAGEMENT SHARING. On an annual basis, NW Natural credits amounts to Oregon and Washington customers as part of a regulatory incentive sharing mechanism related to net revenues earned from Mist gas storage for assets developed in advance of utility customer needs, and asset management revenues. In January 2025, the OPUC approved the annual 2025 bill credit for Oregon customers' share of interstate storage and asset management activities totaling approximately $15.5 million, which was credited to customers' bills in February 2025. This includes revenue generated for the November 2023 through October 2024 PGA year. Credits are given to customers in Washington as reductions in rates through the annual PGA filing in November.
The following table presents the credits to NGD customers:
| | | | | | | | | | | | | | | | | | | | |
| In millions | | 2024 | | 2023 | | 2022 |
| Oregon | | $ | 28.9 | | | $ | 23.5 | | | $ | 41.1 | |
| Washington | | 2.4 | | | 2.9 | | | 1.5 | |
LOW INCOME DISCOUNT TARIFFS.
Oregon
In July 2022, NW Natural received approval from the OPUC for an income-qualifying residential bill discount program. The income threshold for program participation is at or below 60 percent of Oregon state median income (SMI). The program provides a bill discount for income-qualifying residential customers at four discount tier levels based on household income compared to SMI, with higher discounts given for lower income levels. The bill discount percentages were modified effective November 1, 2024 and they are presented in the table below. Participating customers can self-certify their income and household size to qualify for the program directly with NW Natural or their local Community Action Agency. The program was available for qualifying customers starting November 1, 2022. Costs for the bill discount program include simultaneous recovery from all customers. Costs for the bill discount program, inclusive of start-up and administrative costs of the program, are recoverable in rates. The amount deferred to a regulatory asset as of December 31, 2024 was $2.8 million.
| | | | | | | | | | | |
| Total Household Income | | Bill Discount Percentage |
| Tier 0 | At or below 15% SMI | | 85% |
| Tier 1 | 16% - 30% of SMI | | 50% |
| Tier 2 | 31% - 45% of SMI | | 30% |
| Tier 3 | 46% - 60% of SMI | | 15% |
Washington
In December 2023, NW Natural received approval from the WUTC for an income-qualifying residential bill discount program. The program was available for qualifying customers starting January 1, 2024. The Washington program is similar to the Oregon program, with the exception of the discount tier levels shown below. The income threshold for the Washington program participation is based on the greater of area median income (AMI) or federal poverty level (FPL). The amount deferred to a regulatory asset as of December 31, 2024 was $0.3 million.
| | | | | | | | | | | |
| Total Household Income | | Bill Discount Percentage |
| Tier 0 | At or below 60% FPL | | 80% |
| Tier 1 | 61% - 120% of FPL | | 40% |
| Tier 2 | 121% - 150% of FPL | | 20% |
| Tier 3 | Greater of 80% AMI or 151% - 200% of FPL | | 15% |
RENEWABLE NATURAL GAS AND AUTOMATIC ADJUSTMENT CLAUSE. Oregon Senate Bill 98 (SB 98) enables natural gas utilities to procure or develop RNG on behalf of their Oregon customers. SB 98 and the rules outline the following parameters for the RNG program including: setting voluntary goals for adding as much as 30% renewable natural gas into the state’s pipeline system by 2050; enabling gas utilities to invest in and own the cleaning and conditioning equipment required to bring raw biogas and landfill gas up to pipeline quality, as well as the facilities to connect to the local gas distribution system; and allowing up to 5% of a utility’s revenue requirement to be used to cover the incremental cost or investment in renewable natural gas infrastructure.
Further, the law supports all forms of renewable natural gas including renewable hydrogen, which is made from excess wind, solar and hydro power. Renewable hydrogen can be used for the transportation system, industrial use, or blended into the natural gas pipeline system.
NW Natural has two investments in RNG facilities the OPUC has approved for recovery in rates. The first investment is in Lexington Renewables Energy, LLC where the OPUC approved recovery through an automatic adjustment clause that allows for NW Natural's investments in RNG projects, including operating costs, to be added to rates annually on November 1st, following a prudence review. The RNG recovery mechanism allows NW Natural to defer for recovery or credit the differences between the forecasted and actual costs of the RNG projects, subject to an earnings test that includes deadbands at 50 basis points below and above NW Natural's authorized ROE. For 2024, NW Natural has performed this test, which is anticipated to be submitted to the OPUC in May 2025. No earnings test adjustment is expected for 2024.
The second investment is in Dakota City Renewable Energy LLC where the OPUC also approved the investment through an automatic adjustment clause that allows NW Natural to begin recovering the investment costs and expenses of the facility. The Dakota City investment is subject to the earnings test requirements under the RNG recovery mechanism discussed above and is subject to a production risk-sharing mechanism based on the expected per unit of production. NW Natural is required to share 25% of the costs above this threshold.
For RNG procurement contracts, NW Natural seeks recovery of the costs in the PGA and other filings, subject to a prudence review.
METER MODERNIZATION PROGRAM. In January 2024, NW Natural filed a request with the OPUC and WUTC to defer the incremental costs to replace approximately 600,000 meters over four years. The deferral was granted by the WUTC in the first quarter of 2024. The filing is pending with the OPUC. The amount deferred to a regulatory asset as of December 31, 2024 was approximately $1.4 million.
INTEGRATED RESOURCE PLAN (IRP). NW Natural generally files a full IRP biennially for Oregon and Washington with the OPUC and WUTC, respectively. NW Natural jointly filed its 2022 IRP for both Oregon and Washington on September 23, 2022. The 2022 IRP evaluates several varying scenarios based on a range of inputs and outlines the least-cost resources required to meet future demand and environmental compliance obligations. With respect to IRPs generally, the WUTC issues letters of compliance and Oregon acknowledges the IRP Action Plan. In August 2023, NW Natural received a letter of compliance from the WUTC acknowledging compliance of the 2022 IRP. The OPUC issued their order on NW Natural's 2022 IRP in August 2023.
The development of an IRP filing is an extensive and complex process that engages multiple stakeholders in an effort to build a robust and commonly understood analysis. The final product is intended to provide a long-term outlook of the supply-side and demand-side resource requirements for reliable and low-cost natural gas service while also meeting NW Natural's environmental compliance requirements. The IRP examines and analyzes uncertainties in the planning process to evaluate risk, including potential changes in governmental and regulatory policies. The CCA that was passed in Washington is an example of a new policy that resulted in compliance requirements that need to be included in the planning process. We currently expect to file our next full IRP with Oregon and Washington in 2025.
PIPELINE SECURITY. In May and July 2021, the Department of Homeland Security’s (DHS) Transportation Security Administration (TSA) released two security directives applicable to certain owners and operators of natural gas pipeline facilities (including local distribution companies). The first directive require owners and operators to implement cybersecurity incident reporting to the DHS, designate a cybersecurity coordinator, and perform a gap assessment of current entity cybersecurity practices against certain voluntary TSA security guidelines and report relevant results and proposed mitigation to applicable DHS agencies. The second directive requires entities to implement a significant number of specified cybersecurity controls and processes. The TSA updated the second directive as well as clarifying Operational Technology (OT) scope and providing a risk- and outcome-based framework. The TSA continues to renew both directives and is in the process of formulating regulations with the aim of rendering the security directives permanent. NW Natural is currently evaluating and implementing the security directives and related deliverables. NW Natural frequently updates the TSA on its progress on achieving the security directives.
NW Natural received approval from the OPUC and WUTC to defer the costs associated with complying with the TSA's security directives. As of December 31, 2024, NW Natural has invested approximately $46.9 million in information and operational technology. A majority of the capital investment was included in rate base starting November 1, 2022 in Oregon.
NW Natural continues to evaluate the potential effect of these directives on our operations and facilities and will continue to monitor for any clarifications or amendments to these directives. We may seek to request recovery from customers of any additional costs incurred to the extent that incremental expenses and capital expenditures are incurred in the future.
WATER AND WASTEWATER UTILITIES. NWN Water currently serves an estimated 190,000 people through approximately 76,000 connections across six states. NWN Water continues to pursue acquisitions of regulated water and wastewater utilities:
•In the first quarter of 2023, NWN Water signed a purchase agreement for a water utility with approximately 700 connections in Texas. After completing a fair market valuation process through the Public Utility Commission of Texas (PUCT), NWN Water filed the application with the PUCT in the first quarter of 2024. The acquisition is expected to close in the first quarter of 2025.
•In the second quarter of 2024, NWN Water signed a purchase agreement for three water utilities with approximately 200 connections in Oregon. The OPUC approved the application in August 2024 and the acquisition closed in November 2024.
•In the fourth quarter of 2024, NWN Water signed a purchase agreement for a water utility with approximately 1,500 connections in Texas. NWN Water filed its notice of intent to seek fair market valuation with the PUCT in October 2024.
For our regulated water and wastewater utilities, we have been executing general rate cases.
•In October 2023, Foothills water and sewer utilities filed general rate cases with the ACC. The parties filed a settlement agreement in July 2024 and amended agreement in September 2024, which were approved by the ACC in October 2024. Rates were effective on November 1, 2024.
•In February 2024, Cascadia Water filed a general rate case with the WUTC. Cascadia Water and the WUTC filed a settlement agreement in January 2025 and rates are expected to be effective by May 1, 2025.
•In March 2024, Sunriver Water filed a general rate case with the OPUC and rates were effective on November 1, 2024.
•In June 2024, Avion Water filed a general rate case with the OPUC and rates were effective on February 1, 2025.
•In December 2024, Gem State Water filed a general rate case with the IPUC. The IPUC suspended the effective date of rates pending further review.
•In January 2025, Falls Water filed a general rate case with the IPUC.
Environmental Regulation and Legislation Matters
In recent years, there has been an international and domestic focus on climate change and the contribution of GHG emissions, most notably methane and carbon dioxide, to climate change. In response, there have been increasing efforts at the international, federal, state, and local level to regulate GHG emissions. Legislation or other forms of regulation have taken, and could continue to take, a variety of forms including, but not limited to, GHG emissions limits, reporting requirements, carbon taxes, requirements to purchase carbon credits, building codes, increased efficiency standards, additional charges to fund energy efficiency activities or other regulatory actions, incentives or mandates to conserve energy or use renewable energy sources, tax advantages and other subsidies to support alternative energy sources, a reduction in rate recovery for construction costs related to the installation of new customer services or other new infrastructure investments, mandates for the use of specific fuels or technologies, bans on specific fuels or technologies, or promotion of research into new technologies to reduce the cost and increase the scalability of alternative energy sources. These efforts have included, and could continue to include, legislation, legislative proposals, directed government funding, new regulations at the federal, state, and local level, and penalties for noncompliance, as well as private and other third-party litigation related to GHG emissions or regulation thereof. We recognize certain of our businesses, including our natural gas business, are likely to be affected by current or future regulation seeking to regulate GHG emissions.
Federal
A number of federal agencies currently regulate GHG emissions. For example, the EPA regulates GHG emissions pursuant to the Clean Air Act and requires the annual reporting of GHG emissions from certain industries, specified emission sources, and facilities. Under this reporting rule, local natural gas distribution companies like NW Natural are required to report system throughput to the EPA on an annual basis. The EPA also has required additional GHG reporting regulations to which NW Natural is subject, requiring the annual reporting of fugitive emissions from operations.
During his administration, former President Biden issued a number of executive orders directing agencies to conduct a general review of regulations and executive actions related to the environment and reestablished a framework for considering the social cost of carbon as part of certain agency cost-benefit analyses for new regulations. Federal legislation passed under the Biden administration, such as the Inflation Reduction Act of 2022 (IRA), included several climate and energy provisions. In addition, under the Biden administration, a number of federal agencies including the Securities and Exchange Commission (SEC), the Federal Trade Commission, the Federal Energy and Regulatory Commission, PHMSA, and the Commodities Futures Trading Commission (CFTC), had taken or were expected to take, actions related to climate change. Other federal regulatory agencies, including the U.S. Department of Energy, were additionally beginning to address matters related to GHG emissions that may include changes in their regulatory oversight approach, policies and rules.
Upon taking office in January 2025, President Trump issued executive orders directing the U.S. Ambassador to the United Nations to withdraw from the Paris Agreement on Climate and declaring a “national energy emergency” in the United States.
He issued other executive orders described as seeking to promote energy exploration and production in the United States, reducing permitting and other regulatory requirements related to energy exploration and production, freezing certain funding and regulatory rulemaking related to climate-related regulation, and revoking Biden administration executive orders that are related to climate policy. We expect there to be a number of additional changes related to climate policy under the Trump Administration, including additional executive orders, federal regulations, programs and other federal actions. We are currently evaluating the effect of various changes in federal climate policy, regulation and law, and cannot currently predict when or if the Trump Administration or Congress will act, the form of the action, or the impact of those actions on our business.
Washington State
In 2024, Washington comprised approximately 10% of NW Natural’s revenues, as well as 2% and 13% of new meters from commercial and residential customers, respectively. Effective February, 2021, building codes in Washington state require new residential homes to achieve higher levels of energy efficiency based on specified carbon emissions assumptions, which calculate electric appliances to have lower on-site GHG emissions than comparable gas appliances. This increases the cost of new home construction incorporating natural gas depending on a number of factors including home size, equipment configurations, and building envelope measures. Additionally, in March, 2024, the Washington State Building Code Council (SBCC) implemented rules that would have the effect of restricting or eliminating the use of gas space and water heating in new commercial and residential construction, with certain exceptions in residential construction for natural gas-fired heat pumps and hybrid fuel systems.
Subsequently, Washington Ballot initiative I-2066 passed in November 2024. I-2066 was described on the ballot as prohibiting state and local governments from restricting access to natural gas, prohibiting the SBCC from discouraging or penalizing the use of natural gas in any building, requiring providers of natural gas to provide energy services regardless of the other energy sources available, and prohibiting the WUTC from approving any multiyear rate plan requiring or incentivizing a natural gas company to terminate natural gas service or make such natural gas service cost-prohibitive. The SBCC rules, as well as the effect of I-2066 on the validity of the March 2024 SBBC’s rules and the February 2021 Washington buildings codes, are currently subject to legal challenge by a number of companies, organizations and utilities, including NW Natural.
In 2022, the state of Washington enacted the Climate Commitment Act (CCA), which establishes a comprehensive program that includes an overall limit for GHG emissions from major sources in the state that declines yearly beginning January 1, 2023, resulting in an overall reduction of GHG emissions to 95% below 1990 levels by 2050. The Washington Department of Ecology has adopted rules to create a cap-and-invest program, under which entities, including natural gas and electric utilities, large manufacturing facilities, and transportation and other fuel providers, which are subject to the CCA must either reduce their emissions, purchase qualifying offsets (including RNG) or obtain allowances to cover any remaining emissions. NW Natural is subject to the CCA, has received an order authorizing deferral of CCA costs from the WUTC, and is currently recovering CCA compliance costs in rates.
Oregon
In November 2024, the ODEQ issued final cap and reduce rules for its Climate Protection Program (CPP), which became effective in January 1, 2025. The CPP establishes a program to limit GHG emissions from covered entities, including natural gas utilities, by 50% by 2035 and 90% by 2050 from a 2017-2019 baseline. The first compliance period for the CPP concludes December 31. 2027. ODEQ previously promulgated CPP rules in December 2021 (former CPP rules invalidated by the Court of Appeals in December 2023 (Prior CPP)). NW Natural received an order from the OPUC authorizing deferral of Prior CPP compliance costs, and we also expect to pursue inclusion in rates of current CPP compliance costs. The CPP rules are subject to legal challenge.
Local Jurisdictions and Other Advocacy
In addition to legislative activities at the state level, advocacy groups have indicated a willingness to pursue municipal ordinances and ballot measures or other local activities. A number of cities across the country, and several in our service territory are taking action or currently considering actions such as limitations or bans on the use of natural gas in new construction or otherwise. For example, the Eugene City Council directed its City Manager to develop a plan to address GHG emissions and align incentives around GHG emissions and to engage in a number of actions, including identifying potential revenue sources as well as potential consequences of implementing the prior directive. Similarly, some jurisdictions and advocates are seeking to ban the use of natural gas and certain natural gas appliances inside homes contending that there are detrimental indoor health effects associated with the use of natural gas.
NW Natural is actively engaged with federal, state and local policymakers, consumers, customers, small businesses and other business coalitions, economic development practitioners, and other advocates in our service territory and is working with these communities to communicate the role that direct use natural gas, and in the coming years, RNG and hydrogen, can play in pursuing more effective policies to reduce GHGs while supporting reliability, resiliency, energy choice, equity, and energy affordability.
NW Natural Decarbonization Initiatives and Compliance Actions
Our residential customers are currently paying less for their natural gas today than they did 20 years ago. We expect that compliance with any form of regulation of GHG emissions will require additional resources and legislative or regulatory tools, and will increase costs. The developing and changing guidance to implement the CCA and CPP, evolving carbon credit markets and other regulatory tool options, decades-long timeframes for compliance, likely changing and evolving laws and energy policy, and evolving technological advancements, all make it difficult to accurately predict long-term tools for and costs of compliance. We are currently including costs of compliance with the CCA in rates. Compliance costs represent a 4.6% increase on a residential bill, which represents a 7.5% decrease from the prior year. Low income customers do not participate in these compliance costs and are not impacted.
We are not currently able to quantify the extent to which limitations on natural gas use, or declining line extension allowances provided in rates to cover construction costs for new services, will affect new meter additions, or to what extent carbon
compliance costs included in rates will affect the competitiveness of our business and the demand for natural gas service. All of these developments could negatively affect our gas utility customer growth. However, at the same time natural gas utilities will be subject to GHG emissions regulation, we expect that other energy source providers will be subject to similar, or in some cases stricter or more rapid, compliance requirements that are likely to affect their cost and competitiveness relative to natural gas as well. For example, in June 2021, the State of Oregon enacted HB 2021, a clean electricity bill that requires the state’s two largest investor-owned electric utilities and retail electricity service suppliers to reduce GHG emissions associated with electricity sold to Oregon customers to 100 percent below baseline levels by 2040 with interim steps, including an 80 percent reduction by 2030 and 90 percent reduction by 2035. This bill does not replace the separate renewable portfolio standards previously established in Oregon, which sets requirements for how much of the electricity used in Oregon must come from renewable resources. In Washington, SB 5116, the Clean Energy Transformation Act, requires all electric utilities in Washington to transition to carbon-neutral electricity by 2030 and to 100 percent carbon-free electricity by 2045. We expect compliance with these and other laws will increase the cost of energy for electric customers in our service territory. We are not able to determine at this time whether increased electricity costs will make natural gas use more or less competitive on a relative basis.
We expect these and other trends to drive innovation of, and demand for, technological developments and innovative new products that reduce GHG emissions. Research and development are occurring across the energy sector, including in the gas sector with work being conducted on gas heat pumps, higher efficiency water and space heating appliances including hybrid systems, carbon capture utilization and storage developments, continued development of technologies related to RNG, and various forms of hydrogen for different applications, among others.
Business Segment - Natural Gas Distribution (NGD)
NGD margin results are primarily affected by customer growth, revenues from rate-base additions, and, to a certain extent, by changes in delivered volumes due to weather and customers’ gas usage patterns. In Oregon, NW Natural has a conservation tariff (also called the decoupling mechanism), which adjusts margin up or down each month through a deferred regulatory accounting adjustment designed to offset changes resulting from increases or decreases in average use by residential and commercial customers. NW Natural also has a weather normalization tariff in Oregon, WARM, which adjusts customer bills up or down to offset changes in margin resulting from above- or below-average temperatures during the winter heating season. Residential and commercial customers in Oregon are allowed to opt out of the weather normalization mechanism, and as of December 31, 2024, approximately 7% of total eligible customers had opted out. NW Natural does not have a weather normalization mechanism approved for Washington customers, which account for about 12% of total customers. The decoupling and WARM mechanisms are designed to reduce, but not eliminate, the volatility of customer bills and natural gas distribution revenue. See "Regulatory Matters—Rate Mechanisms" above. In addition to NW Natural's local gas distribution business, the NGD segment also includes the portion of the Mist underground storage facility used to serve NGD customers, the North Mist gas storage expansion, NWN Gas Reserves, which is a wholly owned subsidiary of Energy Corp., and NW Natural RNG Holding Company, LLC.
The NGD business is primarily seasonal in nature due to higher gas usage by residential and commercial customers during the cold winter heating months. Other categories of customers experience seasonality in their usage but to a lesser extent. Seasonality affects the comparability of the results of operations of the NGD business across quarters but not across years.

2024 COMPARED TO 2023. NGD net income was $77.1 million in 2024 compared to $94.0 million in 2023. The primary factors contributing to the decrease in NGD net income were as follows:
•$18.2 million decrease in other income, net driven by higher pension non-service costs, lower interest income from invested cash, lower regulatory interest income and a decline in the equity portion of AFUDC;
•$13.7 million decrease due to the disallowance of undepreciated line extension costs as ordered in the 2024 Oregon general rate case;
•$10.1 million increase in depreciation expense from continued capital investments in our system for safety and reliability;
•$2.8 million increase in interest expense primarily due to higher short and long-term debt balances; and
•$2.0 million increase in general taxes primarily driven by higher regulatory commission fees; partially offset by
•$26.3 million increase in NGD margin primarily due to:
▪$25.8 million increase due to new customer rates in Oregon that went into effect November 1, 2024;
▪$3.7 million increase due to the amortization of deferred balances primarily related to COVID-19, cybersecurity, and ERP upgrades; and
▪$2.2 million increase driven by customer growth; partially offset by
▪$4.3 million decrease due to lower usage from warmer comparative weather for customers not covered under the weather normalization mechanism; and
▪$1.8 million decline in gains on the Oregon gas cost incentive sharing mechanism due to market prices more closely approximating prices embedded in the PGA and higher than estimated gas costs during the cold weather event in January 2024; and
•$2.1 million decrease in NGD operations and maintenance expenses (excluding the regulatory disallowance) due to lower contract labor costs and lower bad debt expense, partially offset by higher amortization expense related to cloud computing arrangements.
Total natural gas sold and delivered in 2024 decreased 3% over 2023 primarily due to 17% warmer than average weather in 2024 compared to 8% warmer than average weather in 2023.
2023 COMPARED TO 2022. NGD net income was $94.0 million in 2023 compared to $79.7 million in 2022. The primary factors contributing to the increase in NGD net income were as follows:
•$69.1 million increase in NGD margin primarily due to:
▪$47.5 million increase due to new customer rates in Oregon and Washington that went into effect November 1, 2022;
▪$9.4 million increase due to actual gas prices that were lower than what was estimated in the 2022-2023 PGA;
▪$9.2 million increase due to the amortization of deferred balances primarily related to COVID-19, cybersecurity, and ERP upgrades (which is mostly offset in operations and maintenance expenses and interest expense; and
▪$4.6 million increase driven by customer growth; partially offset by
▪$2.4 million decrease due to warmer than average weather for customers not covered under the weather normalization mechanism.
•$15.8 million increase in other income, net driven by interest income from invested cash and the equity portion of AFUDC, and lower pension costs; partially offset by
•$40.0 million increase in NGD operations and maintenance expenses due to higher payroll costs, higher contract labor, the amortization of deferred balances (which is mostly offset in revenues), information technology costs and amortization expense related to cloud computing arrangements;
•$14.3 million increase in interest expense primarily due to higher long-term debt balances;
•$6.5 million increase in depreciation expense due to additional capital investments in the distribution system, including several significant information technology projects that were placed into service in September 2022; and
•$4.9 million higher income tax expense reflecting higher pre-tax income.
Total natural gas sold and delivered in 2023 increased 4% over 2022 primarily due to 8% warmer than average weather in 2023 compared to 1% colder than average weather in 2022.

(1) Amounts reported as NGD margin for each category of meters are operating revenues less cost of gas, environmental remediation expense and revenue taxes.
(2) Heating degree days are units of measure reflecting temperature-sensitive consumption of natural gas, calculated by subtracting the average of a day's high and low temperatures from 59 degrees Fahrenheit.
(3) Average weather represents the 25-year average of heating degree days. Beginning November 1, 2024, average weather is calculated over the period June 1, 1998 through May 31, 2023, as determined in NW Natural's 2024 Oregon general rate case. From November 1, 2022 through October 31, 2024, average weather was calculated over the period June 1, 1996 through May 31, 2021, as determined in NW Natural's 2022 Oregon general rate case. From November 1, 2020 through October 31, 2022, average weather was calculated over the period June 1, 1994 through May 31, 2019, as determined in NW Natural’s 2020 Oregon general rate case.
Residential and Commercial Sales
The primary factors that impact results of operations in the residential and commercial markets are customer growth, seasonal weather patterns, energy prices, competition from other energy sources, and economic conditions in our service areas. The impact of weather on margin is significantly reduced through NW Natural's weather normalization mechanism in Oregon; approximately 81% of NW Natural's total customers are covered under this mechanism. The remaining customers either opt out of the mechanism or are located in Washington, which does not have a similar mechanism in place. For more information on the weather mechanism, see "Regulatory Matters—Rate Mechanisms—WARM" above.

2024 COMPARED TO 2023. NGD residential and commercial operating revenue decreased $46.4 million and NGD margin increased $28.4 million compared to the prior year. The increase in NGD margin was primarily driven by new customer rates in Oregon that took effect on November 1, 2024 and 0.9% growth in residential customer meters. Sales volumes decreased 26.9 million therms, or 4%, due to lower usage driven by comparatively warmer weather.
2023 COMPARED TO 2022. NGD residential and commercial operating revenue increased $133.7 million and NGD margin increased $56.8 million compared to the prior year. The increase was primarily driven by new customer rates in Oregon and Washington that took effect on November 1, 2022 and 0.6% growth in residential customer meters. Sales volumes decreased 30.8 million therms, or 4%, due to lower usage driven by comparatively warmer weather.
Industrial Sales and Transportation
Industrial customers have the option of purchasing sales or transportation services. Under the sales service, the customer buys the gas commodity from NW Natural. Under the transportation service, the customer buys the gas commodity directly from a third-party gas marketer or supplier. The NGD gas commodity cost is primarily a pass-through cost to customers; therefore, NGD profit margins are not materially affected by an industrial customer's decision to purchase gas from third parties. Industrial and large commercial customers may also select between firm and interruptible service options, with firm services generally providing higher profit margins compared to interruptible services. To help manage gas supplies, industrial tariffs are designed to provide some certainty regarding industrial customers' volumes by requiring an annual service election which becomes effective November 1, special charges for changes between elections, and in some cases, a minimum or maximum volume requirement before changing options.

2024 COMPARED TO 2023. NGD industrial sales and transportation margin decreased $0.6 million compared to the prior year primarily driven by lower sales and transportation volumes. Sales volumes decreased 8.9 million therms, or 2%, primarily due to lower usage from multiple customers, most notably in the pulp and paper, forest products, chemical manufacturing and food processing industries.
2023 COMPARED TO 2022. NGD industrial sales and transportation margin increased $1.2 million compared to the prior year primarily driven by new rates in Oregon and Washington that took effect on November 1, 2022, partially offset by lower sales volumes. Sales volumes decreased 14.8 million therms, or 3%, primarily due to lower usage from multiple customers, most notably in the primary metals, pulp and paper, glass, stone and clay, and chemical manufacturing industries.
Other Regulated Services Margin
Other Regulated Services primarily consist of lease revenues from NW Natural's North Mist storage facility as well as other lease revenues for compressed natural gas assets. See Note 7 for more information regarding North Mist expansion lease accounting.
Other regulated services margin highlights include:
| | | | | | | | | | | | | | | | | | | | |

| Total other regulated services | | $ | 19.5 | | | $ | 18.9 | | | $ | 19.6 | |
2024 COMPARED TO 2023. Other regulated services margin increased $0.6 million compared to the prior year primarily due to an increase in storage service revenue from the North Mist facility. North Mist service revenue increased due to an increase in billing rates from higher operating expenses in 2024.
2023 COMPARED TO 2022. Other regulated services margin decreased $0.7 million compared to the prior year due to lower depreciation rates for the North Mist facility beginning November 1, 2022.
Cost of Gas
Cost of gas as reported by the NGD segment includes gas purchases, gas storage costs, gas commodity derivatives contracts, pipeline demand costs, seasonal demand cost balancing adjustments, renewable natural gas and its attributes, including renewable thermal certificates, regulatory gas cost deferrals, gas reserves costs, and company gas use. The OPUC and WUTC generally require natural gas commodity costs to be billed to customers at the actual cost incurred, or expected to be incurred. Customer rates are set each year so that if cost estimates were met the NGD business would not earn a profit or incur a loss on gas commodity purchases; however, in Oregon we have the incentive sharing mechanism described under "Regulatory Matters—Rate Mechanisms—Purchased Gas Adjustment" above. In addition to the PGA incentive sharing mechanism, gains and losses from hedge contracts entered into after annual PGA rates are effective for Oregon customers are also required to be shared and therefore may impact net income. Further, NW Natural also has a regulatory agreement whereby it earns a rate of return on its investment in the gas reserves acquired under the original agreement with Encana and includes gas from the amended gas reserves agreement at a fixed rate of $0.4725 per therm, which are also reflected in NGD margin. See "Application of Critical Accounting Policies and Estimates—Derivative Instruments and Hedging Activities" below.

(2) For a discussion of the gas cost incentive sharing mechanism, see "Regulatory Matters—Rate Mechanisms—Purchased Gas Adjustment" above.
2024 COMPARED TO 2023. Cost of gas decreased $87.8 million, or 18%, primarily due to a 16% decrease in the average cost of gas and a 4% decrease in volumes sold. Volumes sold decreased 35.1 million due to lower usage from customers driven by comparatively warmer weather. The gain from the Oregon gas cost incentive sharing mechanism declined $1.9 million due to market prices more closely approximating prices embedded in the PGA and higher than estimated gas costs during the cold weather event in January 2024.
2023 COMPARED TO 2022. Cost of gas increased $70.2 million, or 16%, primarily due to a 21% increase in the average cost of gas with these higher gas costs embedded in the 2022-2023 PGA. Volumes sold decreased 32.9 million, or 4%, due to lower usage from customers driven by comparatively warmer weather.
Other
Other activities aggregated and reported as other at NW Holdings include NNG Financial's investment in Kelso-Beaver Pipeline (KB Pipeline); NW Natural Renewables Holdings, LLC and its non-regulated renewable natural gas activities; NWN Water, which owns and continues to pursue investments in the water, wastewater and water services sectors; and NWN Water's investment in Avion Water Company, Inc. (Avion Water). Other activities aggregated and reported as other at NW Natural include the non-NGD storage activity at Mist as well as asset management services and the appliance retail center operations. See Note 4 for further discussion of our business segment and other, as well as our direct and indirect wholly-owned subsidiaries. See Note 13 for information on our Avion Water investment.
At Mist, NW Natural provides gas storage services to customers in the interstate and intrastate markets using storage capacity that has been developed in advance of NGD customers’ requirements. Pre-tax income from gas storage at Mist and asset management services is subject to revenue sharing with NGD customers. Under this regulatory incentive sharing mechanism, NW Natural retains 80% of pre-tax income from Mist gas storage services and asset management services when the underlying costs of the capacity being used are not included in NGD business rates. The remaining 20% is credited to a deferred regulatory account for credit to NGD customers. To the extent that the capacity used is included in NGD rates, NW Natural retains 10% of pre-tax income from such storage and asset management services and 90% is credited to NGD business customers.
The following table presents the results of activities aggregated and reported as other for both NW Holdings and NW Natural:

Other income (expense), net primarily consists of regulatory interest, pension and other postretirement non-service costs, gains
from company-owned life insurance, the equity portion of AFUDC, interest income and donations.
2024 COMPARED TO 2023. Other income, net decreased $18.2 million at NW Natural primarily due to $6.6 million of higher pension non-service costs, $4.1 million of lower interest income from a lower level of invested cash, $2.6 million of lower regulatory interest income and a $2.6 million decline from the equity portion of AFUDC. Costs related to our defined benefit pension plan for 2024 increased compared to the prior year due to an increase in amortization of actuarial losses.
In addition to the $18.2 million decrease at NW Natural, NW Holdings experienced an additional $2.7 million decrease from a settlement gain recognized in 2023, which was partially offset by a decrease in the amount of contributions made by NW Holdings to fund community outreach initiatives in 2024.
2023 COMPARED TO 2022. Other income, net increased $15.8 million at NW Natural primarily due to $5.5 million of interest income from invested cash, $4.1 million from higher equity AFUDC interest income, and $5.8 million of lower pension costs.
Costs related to our defined benefit pension plan for 2023 decreased compared to the prior year due to a decrease in amortization of actuarial losses.
Other income, net increased $16.7 million at NW Holdings driven by the increase at NW Natural discussed above and a $2.7 million gain recognized from a settlement agreement with a third party to settle outstanding receivables, partially offset by contributions to fund community outreach initiatives at NW Holdings.

| Effective tax rate | | 28.0 | % | | 25.4 | % | | 25.3 | % |
2024 COMPARED TO 2023. The effective tax rate increased 2.7% and 2.6% at NW Holdings and NW Natural, respectively. The increase in the effective tax rate is primarily related to a regulatory tax benefit that was fully amortized in customer rates in 2023. The decrease in income tax expense is primarily due to lower pre-tax income in the current period compared to the prior year.
2023 COMPARED TO 2022. The effective tax rate increased 0.4% and 0.1% at NW Holdings and NW Natural, respectively. The increase in the effective tax rate is primarily due to higher pre-tax income in the current period compared to the prior year.
FINANCIAL CONDITION
Capital Structure
NW Holdings' long-term goal is to maintain a strong and balanced consolidated capital structure. NW Natural has historically targeted a regulatory capital structure of 50% common equity and 50% long-term debt, which is consistent with approved regulatory allocations in Oregon, which has an allocation of 50% common equity and 50% long-term debt without recognition of short-term debt. NW Natural has requested a 52% common equity and 48% long-term debt in its current rate case, which has not yet been decided.
When additional capital is required, debt or equity securities are issued depending on both the target capital structure and market conditions. These sources of capital are also used to fund long-term debt retirements and short-term commercial paper maturities. See "Liquidity and Capital Resources" below and Note 9. Achieving our target capital structure and maintaining sufficient liquidity to meet operating requirements is necessary to maintain attractive credit ratings and provide access to the capital markets at reasonable costs.
NW Holdings' consolidated capital structure, excluding short-term debt, was as follows:
| | | | | | | | | | | | | | |
| | December 31, |
| | 2024 | | 2023 |
| Common equity | | 44.8 | % | | 44.9 | % |
| Long-term debt (including current maturities) | | 55.2 | | | 55.1 | |
| Total | | 100.0 | % | | 100.0 | % |
NW Natural's consolidated capital structure, excluding short-term debt, was as follows:
| | | | | | | | | | | | | | |
| | December 31, |
| | 2024 | | 2023 |
| Common equity | | 49.2 | % | | 47.5 | % |
| Long-term debt (including current maturities) | | 50.8 | | | 52.5 | |
| Total | | 100.0 | % | | 100.0 | % |
As of December 31, 2024 and 2023, NW Holdings' consolidated capital structure included common equity of 42.4% and 43.5%, long-term debt of 51.4% and 48.3%, and short-term debt including current maturities of long-term debt of 6.2% and 8.2%, respectively. As of December 31, 2024 and 2023, NW Natural's consolidated capital structure included common equity of 46.9% and 47.2%, long-term debt of 47.2% and 52.2%, and short-term debt including current maturities of long-term debt of 5.9% and 0.6%, respectively.
During 2024, NW Natural's capital structure changed primarily due to the increase in short-term debt and capital contributions from NW Holdings. NW Holdings' capital structure changed primarily due to the issuance of long-term debt and common stock at NW Holdings. See further discussion below in "Cash Flows — Financing Activities".
Liquidity and Capital Resources
At December 31, 2024 and December 31, 2023, NW Holdings had approximately $38.5 million and $32.9 million, and NW Natural had approximately $20.0 million and $19.8 million, of cash and cash equivalents, respectively. In order to maintain sufficient liquidity during periods when capital markets are volatile, NW Holdings and NW Natural may elect to maintain higher cash balances and add short-term borrowing capacity. NW Holdings and NW Natural may also pre-fund their respective capital expenditures when long-term fixed rate environments are attractive. NW Holdings and NW Natural expect to have ample liquidity in the form of cash on hand and from operations and available credit capacity under credit facilities to support funding needs.
ATM Equity Program
In August 2021, NW Holdings initiated an at-the-market (ATM) equity program by entering into an equity distribution agreement under which NW Holdings may issue and sell from time to time shares of common stock, no par value, having an aggregate gross sales price of up to $200 million. In August 2024, the Finance Committee of the NW Holdings' Board of Directors authorized NW Holdings' sale of an additional $200 million in the aggregate gross sales price under the ATM equity program, with the result that a total of $400 million in the aggregate gross sales price has been authorized for issuance and sale under the ATM equity program. NW Holdings is under no obligation to offer and sell common stock under the ATM equity program, which the Finance Committee of the NW Holdings' Board of Directors has authorized through August 2027. Any shares of common stock offered under the ATM equity program are registered on NW Holdings’ universal shelf registration statement filed with the SEC, which expires in August 2027, or will be registered on a subsequent registration statement to be filed by NW Holdings.
During the year ended December 31, 2024, NW Holdings issued and sold 2,382,750 shares of common stock pursuant to the ATM equity program resulting in cash proceeds of $90.3 million, net of fees and commissions paid to agents of $1.6 million. As of December 31, 2024, NW Holdings had $151.6 million of equity available for issuance under the program.
NW Holdings
For NW Holdings, short-term liquidity is primarily provided by cash balances, dividends from its operating subsidiaries, in particular NW Natural, available cash from a multi-year credit facility, and short-term credit facilities. NW Holdings also has a universal shelf registration statement filed with the SEC for the issuance of debt and equity securities. NW Holdings long-term debt and equity issuances are primarily used to provide equity contributions to NW Holdings’ operating subsidiaries for operating and capital expenditures and other corporate purposes. NW Natural also has a universal shelf registration statement filed with the SEC for the issuance of debt securities. NW Holdings' issuance of securities is not subject to regulation by state public utility commissions, but the dividends from NW Natural to NW Holdings are subject to regulatory ring-fencing provisions. NW Holdings guarantees the debt of its wholly-owned subsidiary, NWN Water. See "Long-Term Debt" below for more information regarding NWN Water debt.
As part of the ring-fencing conditions agreed upon with the OPUC and WUTC in connection with the holding company reorganization, NW Natural may not pay dividends or make distributions to NW Holdings if NW Natural’s credit ratings and common equity ratio, defined as the ratio of equity to long-term debt, fall below specified levels. If NW Natural’s long-term
secured credit ratings are below A- for S&P and A3 for Moody’s, dividends may be issued so long as NW Natural’s common equity ratio is 45% or more. If NW Natural’s long-term secured credit ratings are below BBB for S&P and Baa2 for Moody’s, dividends may be issued so long as NW Natural’s common equity ratio is 46% or more. Dividends may not be issued if NW Natural’s long-term secured credit ratings are BB+ or below for S&P or Ba1 or below for Moody’s, or if NW Natural’s common equity ratio is below 44%, where the ratio is measured using common equity and long-term debt excluding imputed debt or debt-like lease obligations. In each case, common equity ratios are determined based on a preceding or projected 13-month average. In addition, there are certain OPUC notice requirements for dividends in excess of 5% of NW Natural’s retained earnings.
Additionally, if NW Natural’s common equity (excluding goodwill and equity associated with non-regulated assets), on a preceding or projected 13-month average basis, is less than 46% of NW Natural’s capital structure, NW Natural is required to notify the OPUC, and if the common equity ratio falls below 44%, file a plan with the OPUC to restore its equity ratio to 44%. This condition is designed to ensure NW Natural continues to be adequately capitalized under the holding company structure. Under the WUTC order, the average common equity ratio must not exceed 56%.
At December 31, 2024 and 2023, NW Natural satisfied the ring-fencing provisions described above.
Based on several factors, including current cash reserves, committed credit facilities, its ability to receive dividends from its operating subsidiaries, in particular NW Natural, and an expected ability to issue long-term debt and equity securities in the capital markets, NW Holdings believes its liquidity is sufficient to meet anticipated near-term cash requirements, including all contractual obligations, investing, and financing activities as discussed in "Cash Flows" below.
NW HOLDINGS DIVIDENDS. Quarterly dividends have been paid on common stock each year since NW Holdings’ predecessor’s stock was first issued to the public in 1951. Annual common stock dividend payments per share, adjusted for stock splits, have increased each year since 1956. The declarations and amount of future dividends to shareholders will depend upon earnings, cash flows, financial condition, NW Natural’s ability to pay dividends to NW Holdings and other factors. The amount and timing of dividends payable on common stock is at the sole discretion of the NW Holdings Board of Directors.
NW Natural
For the NGD business segment, short-term borrowing requirements typically peak during colder winter months when the NGD business borrows money to cover the lag between natural gas purchases and bill collections from customers. Short-term liquidity for the NGD business is primarily provided by cash balances, internal cash flow from operations, proceeds from the sale of commercial paper notes, as well as available cash from multi-year credit facilities, short-term credit facilities, company-owned life insurance policies, the sale of long-term debt, and equity contributions from NW Holdings. NW Natural's long-term debt and contributions from NW Holdings are primarily used to finance NGD capital expenditures, refinance maturing debt, and provide temporary funding for other general corporate purposes of the NGD business.
Based on its current debt ratings (see "Credit Ratings" below), NW Natural has been able to issue commercial paper and long-term debt at attractive rates. In the event NW Natural is not able to issue new long-term debt due to adverse market conditions or other reasons, NW Natural expects that near-term liquidity needs can be met using internal cash flows, issuing commercial paper, receiving equity contributions from NW Holdings, or drawing upon a committed credit facility. NW Natural also has a universal shelf registration statement filed with the SEC for the issuance of secured and unsecured debt securities.
In the event senior unsecured long-term debt ratings are downgraded, or outstanding derivative positions exceed a certain credit threshold, counterparties under derivative contracts could require NW Natural to post cash, a letter of credit, or other forms of collateral, which could expose NW Natural to additional cash requirements and may trigger increases in short-term borrowings while in a net loss position. NW Natural was not required to post collateral at December 31, 2024. See Note 15 below.
Other items that may have a significant impact on NW Natural's liquidity and capital resources include NW Natural's pension contribution requirements and environmental expenditures.
PENSION CONTRIBUTIONS. NW Natural expects to make contributions to its company-sponsored defined benefit plan, which is closed to new employees, over the next several years under applicable laws and regulations. See "Application of Critical Accounting Policies—Pensions and Postretirement Benefits" below and Note 10 for more information.
ENVIRONMENTAL EXPENDITURES. NW Natural expects to continue using cash resources to fund environmental liabilities for future environmental remediation or action. NW Natural has authorizations in Oregon and Washington to defer costs related to remediation of properties that are owned or were previously owned by NW Natural. In Oregon, a Site Remediation and Recovery Mechanism (SRRM) is currently in place to recover prudently incurred costs allocable to Oregon customers, subject to an earnings test. On October 21, 2019 the WUTC authorized an Environmental Cost Recovery Mechanism (ECRM) for recovery of prudently incurred costs allocable to Washington customers beginning November 1, 2019. See Note 17 and "Results of Operations—Regulatory Matters—Environmental Cost Deferral and Recovery" above.
Based on several factors, including current credit ratings, NW Natural's commercial paper program, current cash reserves, committed credit facilities, and an expected ability to issue long-term debt and receive equity contributions from NW Holdings,
NW Natural believes its liquidity is sufficient to meet anticipated near-term cash requirements, including all contractual obligations, and investing and financing activities as discussed in "Cash Flows" below.
NW NATURAL DIVIDENDS. The declarations and amount of future dividends to NW Holdings will depend upon earnings, cash flows, financial condition, the satisfaction of OPUC and WUTC regulatory ring-fencing restrictions, and other factors. The amount and timing of dividends payable on common stock is subject to approval of the NW Natural Board of Directors.
Gas and Pipeline Capacity Purchase Agreements
NW Natural has signed agreements providing for the reservation of firm pipeline capacity under which it is required to make monthly payments for contracted capacity. The pricing component of the monthly payment is established, subject to change, by U.S. or Canadian regulatory bodies, or is established directly with private counterparties, as applicable. In addition, NW Natural has entered into long-term agreements to release firm pipeline capacity. NW Natural also enters into short-term and long-term gas purchase agreements. Refer to Note 16 for gas and pipeline capacity purchase commitments.
NW Natural Renewables is an unregulated subsidiary of NW Natural Holdings established to pursue unregulated RNG activities. In September 2021, a subsidiary of NW Natural Renewables, Ohio Renewables, and a subsidiary of EDL, a global producer of sustainable distributed energy, executed agreements to secure RNG supply from two production facilities that are designed to convert landfill waste gases to RNG (EDL Facilities). The first facility was completed and commenced delivery of RNG to Ohio Renewables in September 2024. Upon reaching this milestone, Ohio Renewables paid $26.0 million to the EDL subsidiary. The second facility was completed and commenced delivery of RNG to Ohio Renewables in December 2024 at which point Ohio Renewables made an additional payment of $25.4 million to the EDL subsidiary.
Alongside these development agreements, Ohio Renewables and the subsidiary of EDL executed agreements for Ohio Renewables to purchase up to an annual specified amount of RNG produced by the EDL Facilities over a 20-year period at a contractually specified price. Under the amended agreements, we currently estimate the amount of RNG purchases based on prices and quantities specified in the agreements to be as follows: approximately $18.9 million in 2025, $18.9 million in 2026, $22.8 million in 2027, $22.8 million in 2028, $24.1 million in 2029 and $532.6 million thereafter.
Gas Sale Agreements
Ohio Renewables has contracted to sell RNG produced by the EDL Facilities up to certain specified volumes in each of calendar years 2024 through 2026 to an investment-grade counterparty. We currently estimate RNG volumes to be sold pursuant to this agreement to be approximately 2,430,000 MMbtu over the life of the agreement, provided that such amounts of RNG are produced by the EDL Facilities during that period.
Ohio Renewables additionally has contracted to sell a fixed-volume of RNG under a long-term agreement with an investment-grade utility beginning in 2025 and extending through 2042. Amounts to be delivered under this agreement are estimated to be 112,500 MMbtu in 2025, 375,000 MMbtu in 2026, 1,950,000 MMbtu annually in 2027 through 2034, and 2,775,000 MMbtu annually in years 2035 through 2042. Under the current contract, if less than 75% of the contracted volumes of RNG are not delivered on an annual basis, Ohio Renewables is obligated to pay the per MMbtu price for volumes between the amount delivered and 75% of the contracted volumes on an annual basis.
Other Purchase Agreements
Other purchase commitments primarily consist of remaining balances under existing purchase orders and gas storage agreements. At December 31, 2024, the amount due over the duration of the purchase agreements totaled $22.5 million. Except for these certain purchase commitments, NW Holdings and NW Natural have no material off-balance sheet financing arrangements.
Short-Term Debt
The primary source of short-term liquidity for NW Holdings is cash balances, dividends from its operating subsidiaries, in particular NW Natural, available cash from a multi-year credit facility, and short-term credit facilities it may enter into from time to time.
The primary source of short-term liquidity for NW Natural is from the sale of commercial paper, available cash from a multi-year credit facility, and short-term credit facilities it may enter into from time to time. In addition to issuing commercial paper or entering into bank loans to meet working capital requirements, including seasonal requirements to finance gas purchases and accounts receivable, short-term debt may also be used to temporarily fund capital requirements. For NW Natural, commercial paper and bank loans are periodically refinanced through the sale of long-term debt or equity contributions from NW Holdings. Commercial paper, when outstanding, is sold through two commercial banks under an issuing and paying agency agreement and is supported by one or more unsecured revolving credit facilities. See “Credit Agreements” below.
At December 31, 2024 and 2023, NW Natural's short-term debt consisted of the following:
| | | | | | | | | | | | | | | | | |
| December 31, 2024 | | December 31, 2023 |
| In millions | Balance Outstanding | Weighted Average Interest Rate(1) | | Balance Outstanding | Weighted Average Interest Rate(1) |
| NW Natural: | | | | | |
| Commercial paper | $ | 136.5 | | 4.8 | % | | $ | 16.8 | | 5.5 | % |

| NW Holdings | $ | 170.1 | | | | $ | 89.8 | | |
(1) Weighted average interest rate on outstanding short-term debt
Credit Agreements
NW Holdings
NW Holdings has a $200 million sustainability-linked credit agreement, with a feature that allows it to request increases in the total commitment amount, up to a maximum of $300 million. In December 2024, the maturity date of the agreement was extended to November 2, 2027, with an available extension of commitments for one additional one-year period, subject to lender approval.
All lenders under the NW Holdings credit agreement are major financial institutions with committed balances and investment grade credit ratings as of December 31, 2024 as follows:
| | | | | |
| In millions | |
| Lender rating, by category | Loan Commitment |
| AA/Aa | $ | 200 | |
| |
| Total | $ | 200 | |
Based on credit market conditions, it is possible one or more lending commitments could be unavailable to NW Holdings if the lender defaulted due to lack of funds or insolvency; however, NW Holdings does not believe this risk to be imminent due to the lenders' strong investment-grade credit ratings. There was $33.6 million and $73.0 million of outstanding balances under the NW Holdings agreement at December 31, 2024 and 2023, respectively.
The NW Holdings credit agreement permits the issuance of letters of credit in an aggregate amount of up to $40 million. The principal amount of borrowings under the credit agreement is due and payable on the maturity date. The credit agreement requires NW Holdings to maintain a consolidated indebtedness to total capitalization ratio of 70% or less. Failure to comply with this covenant would entitle the lenders to terminate their lending commitments and accelerate the maturity of all amounts outstanding. NW Holdings was in compliance with this covenant at December 31, 2024 and 2023, with consolidated indebtedness to total capitalization ratios of 57.6% and 56.5%, respectively.
The NW Holdings credit agreement also requires NW Holdings to maintain debt ratings (which are defined by a formula using NW Natural's credit ratings in the event NW Holdings does not have a credit rating) with Standard & Poor's (S&P) and Moody's Investors Service, Inc. (Moody’s) and notify the lenders of any change in its senior unsecured debt ratings or senior secured debt ratings, as applicable, by such rating agencies. A change in NW Holdings' debt ratings by S&P or Moody’s is not an event of default, nor is the maintenance of a specific minimum level of debt rating a condition of drawing upon the credit agreement. Rather, interest rates on any loans outstanding under the credit agreements are tied to debt ratings and therefore, a change in the debt rating would increase or decrease the cost of any loans under the credit agreements when ratings are changed. NW Holdings maintains a credit rating with S&P of A- and does not currently maintain ratings with Moody's.
NW Holdings had no letters of credit issued and outstanding at December 31, 2024 and 2023.
NW Natural
NW Natural has a sustainability-linked multi-year credit agreement for unsecured revolving loans totaling $400 million, with a feature that allows NW Natural to request increases in the total commitment amount, up to a maximum of $600 million. In December 2024, the maturity date of the agreement was extended to November 3, 2027 with an available extension of commitments for one additional one-year period, subject to lender approval.
All lenders under the NW Natural credit agreement are major financial institutions with committed balances and investment grade credit ratings as of December 31, 2024 as follows:
| | | | | |
| In millions | |
| Lender rating, by category | Loan Commitment |
| AA/Aa | $ | 400 | |
| |
| Total | $ | 400 | |
Based on credit market conditions, it is possible one or more lending commitments could be unavailable to NW Natural if the lender defaulted due to lack of funds or insolvency; however, NW Natural does not believe this risk to be imminent due to the lenders' strong investment-grade credit ratings.
The NW Natural credit agreement permits the issuance of letters of credit in an aggregate amount of up to $60 million. The principal amount of borrowings under the credit agreement is due and payable on the maturity date. There were no outstanding balances under this credit agreement at December 31, 2024 or 2023. The credit agreement requires NW Natural to maintain a consolidated indebtedness to total capitalization ratio of 70% or less. Failure to comply with this covenant would entitle the lenders to terminate their lending commitments and accelerate the maturity of all amounts outstanding. NW Natural was in compliance with this covenant at December 31, 2024 and 2023, with consolidated indebtedness to total capitalization ratios of 53.1% and 52.8%, respectively.
The NW Natural credit agreement also requires NW Natural to maintain credit ratings with S&P and Moody’s and notify the lenders of any change in NW Natural's senior unsecured debt ratings or senior secured debt ratings, as applicable, by such rating agencies. A change in NW Natural's debt ratings by S&P or Moody’s is not an event of default, nor is the maintenance of a specific minimum level of debt rating a condition of drawing upon the credit agreement. Rather, interest rates on any loans outstanding under the credit agreement are tied to debt ratings and therefore, a change in the debt rating would increase or decrease the cost of any loans under the credit agreement when ratings are changed. See "Credit Ratings" below.
NW Natural had no letters of credit outstanding at December 31, 2024 and one letter of credit outstanding at December 31, 2023. In December 2023, NW Natural issued a $15 million letter of credit through its existing credit agreement, which expired January 5, 2024.
Letters of Credit Facility
In January 2024, NW Natural entered into an Uncommitted Letter of Credit and Reimbursement Agreement (LC Reimbursement Agreement), pursuant to which NW Natural agreed to reimburse each Lender acting as an issuing bank (Issuing Bank) thereunder for disbursements in respect of letters of credit (Letters of Credit) issued pursuant to the LC Reimbursement Agreement from time to time. The Company expects to use Letters of Credit issued under the facility created by the LC Reimbursement Agreement (LC Facility) primarily to support its participation in Washington Climate Commitment Act cap-and-invest program auctions.
Although there is no expressly stated maximum amount of Letters of Credit that can be issued or outstanding under the LC Facility, under current regulatory authority from the OPUC, the aggregate sum of Letters of Credit outstanding and available to be drawn under the LC Reimbursement Agreement may not exceed $100 million at any one time. The Issuing Banks have no commitment to issue Letters of Credit under the LC Facility and will have the discretion to limit and condition the terms for the issuance of Letters of Credit (including maximum face amounts) in their sole discretion.
The LC Reimbursement Agreement requires NW Natural to maintain certain ratings with S&P and Moody’s. NW Natural must also notify the Administrative Agent and Lenders of any change in the S&P or Moody’s Ratings, although any such change is not an event of default.
The LC Reimbursement Agreement prohibits NW Natural from permitting Consolidated Indebtedness to be greater than 70% of Total Capitalization, each as defined therein and calculated as of the end of each fiscal quarter of NW Natural. Failure to comply with this financial covenant would constitute an Event of Default under the LC Reimbursement Agreement. The occurrence of this or any other Event of Default would entitle the Administrative Agent to require cash collateral for the LC Exposure, as defined in the LC Reimbursement Agreement, and to exercise all other rights and remedies available to it and the Lenders under the Credit Documents, as defined in the LC Reimbursement Agreement, and under applicable law.
There were no letter of credits issued or outstanding under the LC reimbursement agreement at December 31, 2024.
Credit Ratings
NW Natural's credit ratings are a factor of liquidity, potentially affecting access to the capital markets including the commercial paper market. NW Natural's credit ratings also have an impact on the cost of funds, and may have an impact on the need to post collateral under financial derivative contracts.
The following table summarizes NW Natural's current credit ratings:
| | | | | | | | | | | | | | |
| | S&P | | Moody's |
| Commercial paper (short-term debt) | | A-1 | | P-2 |
| Senior secured (long-term debt) | | AA- | | A2 |
| Senior unsecured (long-term debt) | | n/a | | Baa1 |
| Issuer credit rating | | A+ | | n/a |
| Ratings outlook | | Stable | | Stable |
In November 2024, S&P revised NW Holdings' rating from A to A- and ratings outlook from "negative" to "stable."
The above credit ratings and ratings outlook are dependent upon a number of factors, both qualitative and quantitative, and are subject to change at any time. The disclosure of or reference to these credit ratings is not a recommendation to buy, sell or hold NW Holdings or NW Natural securities. Each rating should be evaluated independently of any other rating.
As part of the ring-fencing conditions agreed upon with the OPUC and WUTC, NW Holdings and NW Natural are required to maintain separate credit ratings, long-term debt ratings, and preferred stock ratings, if any.
Long-Term Debt
Note Purchase Agreement
In December 2023, NW Holdings entered into a Note Purchase Agreement between NW Holdings and the institutional investors named as purchasers therein. The Note Purchase Agreement provides for the issuance of (i) $100.0 million aggregate principal amount of NW Holdings’ 5.78% Senior Notes, Series A, due March 7, 2028 (5.78% Notes) and (ii) $50.0 million aggregate principal amount of NW Holdings’ 5.84% Senior Notes, Series B, due March 7, 2029 (5.84% Notes) in reliance on an exemption from registration under Section 4(a)(2) of the Securities Act of 1933, as amended. The 5.78% Notes and the 5.84% Notes were issued in March 2024, pursuant to the Note Purchase Agreement. The proceeds from the Note Purchase Agreement were used to settle an existing term loan at NW Holdings for $100.0 million and make an equity contribution to NWN Water, which was used to settle an existing term loan for $50.0 million.
Issuance of Long-Term Debt
In December 2024, NW Holdings issued and sold (i) $90.0 million in aggregate principal amount of its 5.52% Senior Notes, Series C, due December 19, 2029 (the 5.52% Notes), and (ii)$45.0 million in aggregate principal amount of its 5.86% Senior Notes, Series D, due December 19, 2034 (the 5.86% Notes, together with the 5.52% Notes, the Notes), to certain institutional investors pursuant to a Note Purchase Agreement dated December 19, 2024 (the Note Purchase Agreement), in reliance on an exemption from registration under Section 4(a)(2) of the Securities Act of 1933, as amended.
The 5.52% Notes and the 5.86% Notes bear interest at the rate of 5.52% and 5.86%, respectively, per annum, payable semi-annually on June 19 and December 19 of each year, commencing June 19, 2025, and will mature on December 19, 2029, and December 19, 2034, respectively. The 5.52% Notes and the 5.86% Notes will be subject to prepayment at the option of NW Holdings, in whole or in part, (i) at any time at a price equal to 100% of the principal amount thereof, plus the applicable “make-whole” premium and accrued and unpaid interest thereon to the date of prepayment, and (ii) at any time on or after November 19, 2029 and September 19, 2034, respectively, at 100% of the principal amount thereof, plus accrued and unpaid interest thereon to the date of prepayment, but without the payment of a “make-whole” premium, in each case, so long as there is no Default or Event of Default under the Note Purchase Agreement.
Interest Rate Swap Agreement
In January 2023, NWN Water entered into an interest rate swap agreement with a major financial institution for $55.0 million that effectively converted variable-rate debt to a fixed rate of 3.80%. Interest payments made between the effective date and expiration date are hedged by the swap agreement. The interest rate swap agreement expires in June 2026, along with the variable-rate debt.
Retirement of Long-Term Debt
The following NW Natural debentures were retired in the periods indicated:

Bankruptcy Ring-fencing Restrictions
As part of the ring-fencing conditions agreed upon with the OPUC and WUTC, NW Natural is required to have one director who is independent from NW Natural management and from NW Holdings and to issue one share of NW Natural preferred stock to an independent third party. NW Natural was in compliance with both of these ring-fencing provisions as of December 31, 2024 and 2023. NW Natural may file a voluntary petition for bankruptcy only if approved unanimously by the Board of Directors of NW Natural, including the independent director, and by the holder of the preferred share.
Cash Flows
Operating Activities
Changes in our operating cash flows are primarily affected by net income or loss, changes in working capital requirements, and other cash and non-cash adjustments to operating results.
| | | | | | | | | | | | | | | | | | | | |
| In millions | | 2024 | | 2023 | | 2022 |
| NW Natural cash provided by operating activities | | $ | 230.7 | | | $ | 281.9 | | | $ | 145.2 | |
| NW Holdings cash provided by operating activities | | 200.3 | | | 279.9 | | | 147.7 | |
2024 COMPARED TO 2023. The significant factors contributing to the $51.1 million decrease at NW Natural cash flow provided by operating activities were as follows:
•$64.8 million decrease in accounts receivable due to comparatively warmer weather in the current year;
•$20.5 million increase in contributions to our defined benefit pension plan;
•$18.4 million increase in asset optimization revenue sharing bill credits to customers; and
•$15.7 million decrease in net income; partially offset by
•$22.8 million decrease in accounts payable resulting from payments of higher priced gas in the prior year;
•$21.6 million decrease in inventories due to higher priced gas and more gas withdrawn from storage in the prior year; and
•$16.6 million increase in the decoupling mechanism primarily due to lower usage driven by comparatively warmer weather.
The $79.7 million decrease in cash provided by operating activities at NW Holdings was primarily driven by the factors discussed above. In addition, Ohio Renewables paid $51.4 million to a subsidiary of EDL in connection with two RNG facilities.
2023 COMPARED TO 2022. The significant factors contributing to the $136.7 million increase at NW Natural cash flow provided by operating activities were as follows:
•$126.6 million decrease in accounts receivable due to colder weather in December 2022;
•$40.0 million decrease in net deferred gas costs due to the recovery of higher priced gas in 2022;
•$30.6 million decrease in asset optimization revenue sharing bill credits; and
•$19.9 million increase due to a compliance obligation related to the Washington CCA; partially offset by
•$64.9 million decrease in accounts payable resulting from payments of higher priced gas purchased in December 2022; and
•$22.3 million decrease in the decoupling mechanism.
The $132.3 million increase in cash provided by operating activities at NW Holdings was primarily driven by the factors discussed above.
NW Natural made $20.5 million of cash contributions to its qualified defined benefit pension plans during the year ended December 31, 2024 and no cash contributions during the year ended December 31, 2023. The American Rescue Plan, which was signed into law on March 11, 2021, includes a provision for pension relief that extends the amortization period for required contributions from 7 to 15 years and provides for the stabilization of interest rates used to calculate future required contributions. The amount and timing of future contributions will depend on market interest rates and investment returns on the plans’ assets. See Note 10.
NW Holdings and NW Natural have lease and purchase commitments relating to our operating activities that are financed with cash flows from operations. For information on cash flow requirements related to leases and other purchase commitments, see Note 7 and Note 16.
Investing Activities
| | | | | | | | | | | | | | | | | | | | |
| In millions | | 2024 | | 2023 | | 2022 |
| NW Natural cash used in investing activities | | $ | (357.6) | | | $ | (290.5) | | | $ | (320.3) | |
| NW Holdings cash used in investing activities | | (429.0) | | | (335.5) | | | (435.5) | |
2024 COMPARED TO 2023. Cash used in investing activities increased $67.2 million at NW Natural and $93.5 million at NW Holdings, respectively. The increase at NW Natural and NW Holdings is primarily driven by higher capital expenditures as we continue to invest in our natural gas, water and wastewater utility systems. In addition, NWN Water completed the acquisition of Infrastructure Capital Holdings in 2024 and paid $29.9 million in cash consideration.
2023 COMPARED TO 2022. Cash used in investing activities decreased $29.8 million at NW Natural and $100.0 million at NW Holdings, respectively. The decrease at NW Natural is primarily driven by a decrease in capital expenditures related to two significant information technology projects that were placed into service in the prior year.
The decrease in cash used in investing activities at NW Holdings is driven by lower capital expenditures at NW Natural and less cash used for water and wastewater acquisitions.
NW Holdings capital expenditures for 2025 are expected to be in the range of $450 million to $500 million and for the six-year period from 2025 to 2030 are expected to range from $2.5 billion to $2.7 billion. NW Natural capital expenditures for 2025 are expected to be in the range of $330 million to $360 million and for the six-year period from 2025 to 2030 are expected to be approximately 70% of NW Holdings expected cap-ex range. SiEnergy capital expenditures for 2025 are expected to be in the range of $65 million to $75 million. NW Natural Water capital expenditures for 2025 are expected to be in the range of $55 million to $65 million.
The timing and amount of the core capital expenditures and projects for 2025 and the next six years could change based on regulation, growth, and cost estimates. Additional investments in our infrastructure during and after 2025 that are not incorporated in the estimates provided above will depend largely on additional regulations, growth, and expansion opportunities. Required funds for the investments are expected to be internally generated or financed with long-term debt or equity, as appropriate.
Financing Activities
| | | | | | | | | | | | | | | | | | | | |
| In millions | | 2024 | | 2023 | | 2022 |
| NW Natural cash provided by financing activities | | $ | 119.8 | | | $ | 20.4 | | | $ | 178.9 | |
| NW Holdings cash provided by financing activities | | 227.1 | | | 64.2 | | | 301.6 | |
2024 COMPARED TO 2023. Cash provided by financing activities increased $99.4 million at NW Natural primarily driven by higher short-term debt borrowings, lower long-term debt maturities and higher cash contributions from NW Holdings, partially offset by lower long-term debt issuances.
Cash provided by financing activities increased $162.9 million at NW Holdings primarily driven by higher short-term debt borrowings and higher proceeds from common stock issuances, partially offset by higher long-term debt maturities and lower long-term debt issuances.
2023 COMPARED TO 2022. Cash provided by financing activities decreased $158.5 million at NW Natural attributable to lower cash contributions from NW Holdings and the retirement of short and long-term debt, partially offset by an increase in long-term debt issuances.
Cash provided by financing activities decreased $237.4 million at NW Holdings attributable to lower proceeds from common stock issuances and the retirement of short and long-term debt, partially offset by an increase in long-term debt issuances.
Pension Cost and Funding Status of Qualified Retirement Plans
NW Natural's pension costs are determined in accordance with accounting standards for compensation and retirement benefits. See “Application of Critical Accounting Policies and Estimates – Pensions and Postretirement Benefits” below. Pension expense for NW Natural's qualified defined benefit plan, which is allocated between operations and maintenance expenses and capital expenditures, totaled $4.1 million in 2024, a change of $6.5 million from 2023. The fair market value of pension assets in this plan increased to $284.1 million at December 31, 2024 from $283.4 million at December 31, 2023. The increase was due to an increase in employer contributions of $20.5 million and a gain on plan assets of $4.9 million, partially offset by benefit payments of $24.6 million.
Contributions made to NW Natural's company-sponsored qualified defined benefit pension plan are based on actuarial assumptions and estimates, tax regulations, and funding requirements under federal law. The qualified defined benefit pension plan was underfunded by $88.7 million at December 31, 2024. The American Rescue Plan, which was signed into law on March 11, 2021, includes a provision for pension relief that extends the amortization period for required contributions from 7 to 15 years and provides for the stabilization of interest rates used to calculate future required contributions. As a result, NW Natural did not make any plan contributions during 2023. NW Natural made $20.5 million of cash contributions to its qualified defined benefit pension plans during the year ended December 31, 2024. The amount and timing of future contributions will depend on market interest rates and investment returns on the plan's assets. See Note 10 for information regarding employer contributions and estimated future benefit payments and other pension disclosures.
Contingent Liabilities
Loss contingencies are recorded as liabilities when it is probable that a liability has been incurred and the amount of the loss is reasonably estimable in accordance with accounting standards for contingencies. See “Application of Critical Accounting Policies and Estimates—Environmental Contingencies” below. At December 31, 2024, NW Natural's total estimated liability related to environmental sites was $160.0 million. See Note 17 and "Results of Operations—Regulatory Matters—Rate Mechanisms—Environmental Cost Deferral and Recovery" above.
New Accounting Pronouncements
For a description of recent accounting pronouncements that may have an impact on our financial condition, results of operations, or cash flows, see Note 2.
APPLICATION OF CRITICAL ACCOUNTING POLICIES AND ESTIMATES
In preparing financial statements in accordance with U.S. GAAP, management exercises judgment to assess the potential outcomes and related accounting impacts in the selection and application of accounting principles, including making estimates and assumptions that affect reported amounts of assets, liabilities, revenues, expenses, and related disclosures in the financial statements. Management considers critical accounting policies to be those which are most important to the representation of financial condition and results of operations and which require management’s most difficult and subjective or complex judgments, including accounting estimates that could result in materially different amounts if reported under different conditions or used different assumptions. Our most critical estimates and judgments for both NW Holdings and NW Natural include accounting for:
•regulatory accounting;
•revenue recognition;
•derivative instruments and hedging activities;
•pensions and postretirement benefits;
•income taxes;
•environmental contingencies; and
•impairment of long-lived assets and goodwill.
Management has discussed its current estimates and judgments used in the application of critical accounting policies with the Audit Committees of the Boards of NW Holdings and NW Natural. Within the context of critical accounting policies and estimates, management is not aware of any reasonably likely events or circumstances that would result in materially different amounts being reported.
Regulatory Accounting
The NGD segment is regulated by the OPUC and WUTC, which establish the rates designed to recover specific costs of providing regulatory services, and, to a certain extent, set forth special accounting treatment for certain regulatory transactions for which NW Natural records regulatory assets and liabilities. In general, the same accounting principles as non-regulated companies reporting under U.S. GAAP are used. However, authoritative guidance for regulated operations (regulatory accounting) requires different accounting treatment for regulated companies to show the effects of such regulation. For example, NW Natural accounts for the cost of gas using a PGA deferral and cost recovery mechanism, which is submitted for approval annually to the OPUC and WUTC. See "Results of Operations—Regulatory Matters—Rate Mechanisms—Purchased Gas Adjustment" above. There are other expenses and revenues that the OPUC or WUTC may require NW Natural to defer for recovery or refund in future periods. Regulatory accounting requires NW Natural to account for these types of deferred expenses (or deferred revenues) as regulatory assets (or regulatory liabilities) on the balance sheet. When the recovery of these regulatory assets from, or refund of regulatory liabilities to, customers is approved, NW Natural recognizes the expense or revenue on the income statement at the same time the adjustment to amounts is included in rates charged to customers.
The conditions that must be satisfied to adopt the accounting policies and practices of regulatory accounting include:
•an independent regulator sets rates;
•the regulator sets the rates to cover specific costs of delivering service; and
•the service territory lacks competitive pressures to reduce rates below the rates set by the regulator.
Because NW Natural's NGD operations satisfy all three conditions, NW Natural continues to apply regulatory accounting to NGD operations. Future accounting changes, regulatory changes, or changes in the competitive environment could require NW Natural to discontinue the application of regulatory accounting for some or all of our regulated businesses. This would require the write-off of those regulatory assets and liabilities that would no longer be probable of recovery from or refund to customers.
Based on current accounting and regulatory competitive conditions, NW Natural believes it is reasonable to expect continued application of regulatory accounting for NGD activities. Further, it is reasonable to expect the recovery or refund of NW Natural's regulatory assets and liabilities at December 31, 2024 through future customer rates. If it is determined that all or a portion of these regulatory assets or liabilities no longer meet the criteria for continued application of regulatory accounting, then NW Natural would be required to write-off the net unrecoverable balances against earnings in the period such determination is made. The net balance in regulatory asset and liability accounts was a net liability of $333.4 million and a net liability of $268.2 million as of December 31, 2024 and 2023, respectively. See Note 2 for more detail on regulatory balances.
Revenue Recognition
Revenues, which are derived primarily from the sale, transportation, and storage of natural gas, are recognized upon the delivery of gas commodity or services rendered to customers.
Accrued Unbilled Revenue
For a description of the policy regarding accrued unbilled revenue, most of which relates to the NGD business at NW Natural, see Note 2. The following table presents changes in key metrics if the estimated percentage of unbilled volume at December 31 was adjusted up or down by 1%:
| | | | | | | | | | | | | | |
| | 2024 |
| In millions | | Up 1% | | Down 1% |
Unbilled revenue increase (decrease)(1) | | $ | 1.4 | | | $ | (1.4) | |
Margin increase (decrease)(1) | | 0.2 | | | (0.2) | |
Net income before tax increase (decrease)(1) | | 0.1 | | | (0.1) | |
(1) Includes impact of regulatory mechanisms including decoupling mechanism and excludes the impact of unbilled revenue from water services.
Derivative Instruments and Hedging Activities
NW Holdings and NW Natural have financial derivative policies that set forth guidelines for using financial derivative instruments to support prudent risk management strategies. These policies specifically prohibit the use of derivatives for speculative purposes. Financial derivative contracts are utilized to hedge most of our natural gas sale requirements. These contracts include swaps, options, and combinations of option contracts. NW Natural primarily uses these derivative financial instruments to manage commodity price variability. A small portion of NW Natural's derivative hedging strategy involves foreign currency exchange contracts.
Derivative instruments are recorded on the balance sheet at fair value. If certain regulatory conditions are met, then the derivative instrument fair value is recorded together with an offsetting entry to a regulatory asset or liability account pursuant to
regulatory accounting, and no unrealized gain or loss is recognized in current income or loss. See "Regulatory Accounting" above for additional information. The gain or loss from the fair value of a derivative instrument subject to regulatory deferral is included in the recovery from, or refund to, NGD business customers in future periods. If a derivative contract is not subject to regulatory deferral, then the accounting treatment for unrealized gains and losses is recorded in accordance with accounting standards for derivatives and hedging which is either in current income or loss or in accumulated other comprehensive income or loss (AOCI or AOCL). Derivative contracts outstanding at December 31, 2024, 2023 and 2022 were measured at fair value using models or other market accepted valuation methodologies derived from observable market data. Estimates of fair value may change significantly from period-to-period depending on market conditions, notional amounts, and prices. These changes may have an impact on results of operations, but the impact would generally be mitigated due to the majority of derivative activities being subject to regulatory deferral treatment. For more information on derivative activity and associated regulatory treatment, see Note 2 and Note 15.
The following table summarizes the amount of gains (losses) realized from commodity price transactions for the last three years:

Realized gains and losses from commodity hedges shown above were recorded in cost of gas and were, or will be, included in annual PGA rates.
NWN Water also used financial derivatives to hedge interest rate risk in the form of a pay-fixed interest rate swap. Unrealized gains and losses related to the interest rate swap agreement qualifies for cash flow hedge accounting and are recorded in AOCI on the consolidated balance sheet.
Pensions and Postretirement Benefits
NW Natural maintains a qualified non-contributory defined benefit pension plan, non-qualified supplemental pension plans for eligible executive officers and certain key employees, and other postretirement employee benefit plans covering certain non-union employees. NW Natural also has a qualified defined contribution plan (Retirement K Savings Plan) for all eligible employees. Only the qualified defined benefit pension plan and Retirement K Savings Plan have plan assets, which are held in qualified trusts to fund the respective retirement benefits. The qualified defined benefit retirement plan for union and non-union employees was closed to new participants several years ago. Non-union and union employees hired or re-hired after December 31, 2006 and 2009, respectively, and employees of certain NW Holdings subsidiaries are provided an enhanced Retirement K Savings Plan benefit. The postretirement Welfare Benefit Plan for non-union employees was also closed to new participants several years ago.
Net periodic pension and postretirement benefit costs (retirement benefit costs) and projected benefit obligations (benefit obligations) are determined using a number of key assumptions, including discount rates, rate of compensation increases, retirement ages, mortality rates and an expected long-term return on plan assets. See Note 10.
The vested benefit obligation for the defined benefit pension plan is the actuarial present value of the vested benefits to which the employee is entitled based on the employee's expected date of separation or retirement based on valuation assumptions.
Accounting standards also require balance sheet recognition of unamortized actuarial gains and losses and prior service costs in AOCI or AOCL, net of tax. However, the retirement benefit costs related to qualified defined benefit pension and postretirement benefit plans are generally recovered in rates charged to NGD customers, which are set based on accounting standards for pensions and postretirement benefit expenses. As such, NW Natural received approval from the OPUC to recognize the unamortized actuarial gains and losses and prior service costs as a regulatory asset or regulatory liability based on expected rate recovery, rather than including it as AOCI or AOCL under common equity. See "Regulatory Accounting" above and Note 2, "Industry Regulation."
A number of factors, as discussed above, are considered in developing pension and postretirement benefit assumptions. For the December 31, 2024 measurement date, NW Natural reviewed and updated:
•the weighted-average discount rate assumptions for pensions increased from 4.98% for 2023 to 5.56% for 2024, and the weighted-average discount rate assumptions for other postretirement benefits increased from 4.98% for 2023 to 5.53% for 2024. The new rate assumptions were determined for each plan based on a matching of benchmark interest rates to the estimated cash flows, which reflect the timing and amount of future benefit payments. Benchmark interest rates are drawn from the FTSE Above Median Curve, which consists of high quality bonds rated AA- or higher by S&P or Aa3 or higher by Moody’s;
•the expected annual rate of future compensation is separately determined for bargaining unit and non-bargaining unit employees. The rate assumption ranges from 4.8% to 5.1% in 2025 and thereafter;
•the expected long-term return on qualified defined benefit plan assets remained the same at 7.50% in 2023 and 2024; and
•other key assumptions, which were based on actual plan experience and actuarial recommendations.
At December 31, 2024, the net pension liability (benefit obligations less market value of plan assets) for the defined benefit pension plan decreased $20.5 million compared to 2023. The decrease in the net pension liability is primarily due to the $19.8 million decrease to the pension benefit obligation and the $0.7 million increase in plan assets. The liability for non-qualified plans decreased $0.1 million and the liability for other postretirement benefits increased $0.6 million in 2024.
The expected long-term rate of return on assets is based on a forward-looking capital markets model along with the defined benefit pension plan current and target asset allocation. The model inputs are based on future expected long-term total returns and historical volatilities for various asset classes, along with their historical correlations. The model considers current investment-grade yields for fixed income investments, and the same plus a risk premium for riskier assets such as common stocks.
NW Natural believes its pension assumptions are appropriate based on plan design and an assessment of market conditions. The following shows the sensitivity of retirement benefit costs and benefit obligations to changes in certain actuarial assumptions:
| | | | | | | | | | | | | | | | | | | | |
| Dollars in millions | | Change in Assumption | | Impact on 2024 Retirement Benefit Costs | | Impact on Retirement
Benefit Obligations at Dec. 31, 2024 |
| Discount rate: | | (0.25) | % | | | | |
| Qualified defined benefit plans | | | | $ | 1.1 | | | $ | 9.7 | |
| Non-qualified plans | | | | — | | | 0.1 | |
| Other postretirement benefits | | | | — | | | 0.5 | |
| Expected long-term return on plan assets: | | (0.25) | % | | | | |
| Qualified defined benefit plans | | | | 0.8 | | | N/A |
Income Taxes
Valuation Allowances
Deferred tax assets are recognized to the extent that these assets are believed to be more likely than not to be realized. In making such a determination, available positive and negative evidence is considered, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. NW Holdings and NW Natural have determined that all recorded deferred tax assets are more likely than not to be realized as of December 31, 2024. See Note 11.
Uncertain Tax Benefits
The calculation of tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in the jurisdictions in which we operate. A tax benefit from a material uncertain tax position will only be recognized when it is more likely than not that the position, or some portion thereof, will be sustained upon examination, including resolution of any related appeals or litigation processes, on the basis of the technical merits. NW Holdings and NW Natural participate in the Compliance Assurance Process (CAP) with the Internal Revenue Service (IRS). Under the CAP program companies work with the IRS to identify and resolve material tax matters before the federal income tax return is filed each year. No reserves for uncertain tax benefits were recorded during 2024, 2023, or 2022. See Note 11.
Tax Legislation
When significant proposed or enacted changes in income tax rules occur, we consider whether there may be a material impact to our financial position, results of operations, cash flows, or whether the changes could materially affect existing assumptions used in making estimates of tax related balances.
The final tangible property regulations applicable to all taxpayers were issued on September 13, 2013 and were generally effective for taxable years beginning on or after January 1, 2014. In April 2023, the IRS published Revenue Procedure 2023-15 that provides a safe harbor method of income tax accounting for determining when expenditures for natural gas transmission and distribution property must be capitalized or are allowable as repair deductions. We have evaluated this new safe harbor and do not believe that the safe harbor method is materially different from NW Natural’s current repairs methodology or that this additional guidance would have a material effect on our financial condition and results of operations.
Regulatory Matters
Regulatory tax assets and liabilities are recorded to the extent it is probable they will be recoverable from, or refunded to, customers in the future. At December 31, 2024 and 2023, NW Natural had net regulatory income tax assets of $5.8 million and $8.0 million, respectively, representing future rate recovery of deferred tax liabilities resulting from differences in NGD plant financial statement and tax bases and NGD plant removal costs. These regulatory assets are currently being recovered through customer rates. At December 31, 2024 and 2023, regulatory income tax assets of $6.0 million and $4.9 million, respectively, were recorded by NW Natural, representing future rate recovery of deferred tax liabilities resulting from the equity portion of AFUDC. These regulatory assets are currently being recovered through customer rates.
At December 31, 2024 and 2023, regulatory liability balances, representing the estimated net benefit to NGD customers resulting from the change in deferred taxes as a result of the Tax Cut and Jobs Act (TCJA), of $169.5 million and $174.2 million, respectively, were recorded by NW Natural. These balances include a gross up for income taxes of $44.9 million and $46.1 million, respectively. These regulatory liabilities are currently being amortized as a reduction in customer rates.
Environmental Contingencies
Environmental liabilities are accounted for in accordance with accounting standards under the loss contingency guidance when it is probable that a liability has been incurred and the amount of the loss is reasonably estimable. Amounts recorded for environmental contingencies take numerous factors into consideration, including, among other variables, changes in enacted laws, regulatory orders, estimated remediation costs, interest rates, insurance proceeds, participation by other parties, timing of payments, and the input of legal counsel and third-party experts. Accordingly, changes in any of these variables or other factual circumstances could have a material impact on the amounts recorded for our environmental liabilities. For a complete discussion of environmental accounting policies refer to Note 2. For a discussion of current environmental sites and liabilities refer to Note 17. In addition, for information regarding the regulatory treatment of these costs and NW Natural's regulatory recovery mechanism, see "Results of Operations—Regulatory Matters—Rate Mechanisms—Environmental Cost Deferral and Recovery" above.
Impairment of Long-Lived Assets and Goodwill
Long-Lived Assets
We review the carrying value of long-lived assets whenever events or changes in circumstances indicate the carrying amount of the assets might not be recoverable. Factors that would necessitate an impairment assessment of long-lived assets include a significant adverse change in the extent or manner in which the asset is used, a significant adverse change in legal factors or business climate that could affect the value of the asset, or a significant decline in the observable market value or expected future cash flows of the asset, among others.
When such factors are present, we assess the recoverability by determining whether the carrying value of the asset will be recovered through expected future cash flows. An asset is determined to be impaired when the carrying value of the asset exceeds the expected undiscounted future cash flows from the use and eventual disposition of the asset. If an impairment is indicated, we record an impairment loss for the difference between the carrying value and the fair value of the long-lived assets. Fair value is estimated using appropriate valuation methodologies, which may include an estimate of discounted cash flows.
Goodwill and Business Combinations
In a business combination, goodwill is initially measured as any excess of the acquisition-date fair value of the consideration transferred over the acquisition-date fair value of the net identifiable assets acquired.
The carrying value of goodwill is reviewed annually during the fourth quarter, or whenever events or changes in circumstance indicate that such carrying values may not be recoverable.
NW Holdings' policy for goodwill assessments begins with a qualitative analysis in which events and circumstances are evaluated, including macroeconomic conditions, industry and market conditions, regulatory environments, and the overall financial performance of the reporting unit. If the qualitative assessment indicates that the carrying value may be at risk of recoverability, a quantitative evaluation is performed to measure the carrying value against the fair value of the reporting unit. This evaluation may involve the assessment of future cash flows and other subjective factors for which uncertainty exists and could impact the estimation of future cash flows. These factors include, but are not limited to, the amount and timing of future cash flows, future growth rates, and the discount rate. Unforeseen events and changes in circumstances or market conditions could adversely affect these estimates, which could result in an impairment charge. A qualitative assessment was performed during the fourth quarter of 2024 which indicated a quantitative assessment was not required; thus, no goodwill impairment was recorded. See Note 2 and Note 14 for additional information.
Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the aggregate of the consideration transferred, measured at fair value at the acquisition date, and the fair value of any non-controlling interest in the acquiree. Acquisition-related costs are expensed as incurred. When NW Natural acquires a business, it assesses the financial assets acquired and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions as of the acquisition date. When there is substantial judgment or uncertainty around the fair value of acquired assets, we may engage a third party expert to assist in determining the fair values of certain assets or liabilities.
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
NW Holdings and NW Natural are exposed to various forms of market risk including commodity supply risk, commodity price risk, interest rate risk, foreign currency risk, credit risk and weather risk. The following describes NW Holdings' and NW Natural's exposure to these risks, as applicable.
Commodity Supply Risk
NW Natural enters into spot, short-term, and long-term natural gas supply contracts, along with associated pipeline transportation contracts, to manage commodity supply risk. NW Natural has arranged for physical delivery of an adequate supply of gas, including gas in its Mist storage facility and other off-system storage facilities, to meet expected requirements of core NGD customers. NW Natural's long-term gas supply contracts are primarily index-based and subject to monthly re-pricing, a strategy that is intended to substantially mitigate credit exposure to physical gas counterparties. Absolute notional amounts under physical gas contracts related to open positions on derivative instruments were 561 million therms and 572 million therms as of December 31, 2024 and 2023, respectively.
Commodity Price Risk
Natural gas commodity prices are subject to market fluctuations due to unpredictable factors including weather, pipeline transportation congestion, drilling technologies, market speculation, governmental tariffs and other factors that affect supply and demand. Commodity price risk is primarily hedged with financial swaps, storage and physical gas reserves from a long-term investment in working interests in gas leases operated by Jonah Energy. These hedges are generally included in NW Natural's annual PGA filing for recovery, subject to a regulatory prudence review. Notional amounts under financial derivative contracts were $303.7 million and $405.7 million as of December 31, 2024 and 2023, respectively. The fair value of financial swaps, based on market prices at December 31, 2024, was an unrealized loss of $82.7 million, which would result in cash outflows of $71.3 million in 2025, $10.0 million in 2026, and $1.4 million in 2027.
Interest Rate Risk
NW Holdings and NW Natural are exposed to interest rate risk primarily associated with debt financing needed to fund capital requirements, including future contractual obligations and maturities of long-term and short-term debt. Interest rate risk is primarily managed through the issuance of fixed-rate debt with varying maturities. NW Holdings and NW Natural may also enter into financial derivative instruments, including interest rate swaps, options and other hedging instruments, to manage and mitigate interest rate exposure. NW Holdings and NWN Water entered into interest rate swaps transactions for a total notional amount of $155 million to manage variable interest rate risk in December 2022. Unrealized gains related to these interest rate swap agreements totaled $0.2 million and $0.2 million, net of tax, as of December 31, 2024 and 2023, respectively.
Foreign Currency Risk
The costs of certain pipeline fees are subject to changes in the value of the Canadian currency in relation to the U.S. currency. Foreign currency forward contracts are used to hedge against fluctuations in exchange rates for NW Natural's commodity-related demand and reservation charges paid in Canadian dollars. Notional amounts under foreign currency forward contracts were $10.3 million and $11.9 million as of December 31, 2024 and 2023, respectively. If all of the foreign currency forward contracts had been settled on December 31, 2024, a loss of $0.5 million would have been realized. See Note 15.
Credit Risk
Credit Exposure to Natural Gas Suppliers
Certain gas suppliers have either relatively low credit ratings or are not rated by major credit rating agencies. To manage this supply risk, NW Natural purchases gas from a number of different suppliers at liquid exchange points. NW Natural evaluates and monitors suppliers’ creditworthiness and maintains the ability to require additional financial assurances, including deposits, letters of credit, or surety bonds, in case a supplier defaults. In the event of a supplier’s failure to deliver contracted volumes of gas, the NGD business would need to replace those volumes at prevailing market prices, which may be higher or lower than the original transaction prices. NW Natural expects these costs would be subject to its PGA sharing mechanism discussed above. Since most of NW Natural's commodity supply contracts are priced at the daily or monthly market index price tied to liquid exchange points, and NW Natural has adequate storage flexibility, NW Natural believes it is unlikely a supplier default would have a material adverse effect on its financial condition or results of operations.
Credit Exposure to Financial Derivative Counterparties
NW Natural did not have any counterparty credit exposure related to commodity swap counterparties based on their estimated fair value at December 31, 2024. NW Natural does not have credit exposure to financial commodity swap derivative counterparties when the value of contracts in an unrealized loss position exceeds that of contracts in an unrealized gain position. The net unrealized loss position occurs when forward market prices are lower than our hedge prices. NW Natural’s credit exposure also includes interest rate swap and foreign exchange forward counterparties, neither of which were significant at December 31, 2024. NW Natural's financial derivatives policy requires counterparties to have at least an investment-grade credit rating at the time the derivative instrument is entered into and specific limits on the potential financial exposure and duration based on each counterparty’s credit rating. NW Natural actively monitors and manages derivative credit exposure and places counterparties on hold for trading purposes or requires cash collateral, letters of credit, or guarantees as circumstances warrant.
The following table summarizes NW Natural's overall financial swap and option credit exposure, based on estimated fair value, and the corresponding counterparty credit ratings. The table uses credit ratings from S&P and Moody’s, reflecting the higher of the S&P or Moody’s rating or a middle rating if the entity is split-rated with more than one rating level difference:
| | | | | | | | | | | | | | |
| | Financial Derivative Position by Credit Rating
Unrealized Fair Value Gain (Loss) |
| In millions | | 2024 | | 2023 |
| | | | |
| AA/Aa | | $ | (71.9) | | | $ | (100.7) | |
| A/A | | (10.8) | | | (14.8) | |
| | | | |
| Total | | $ | (82.7) | | | $ | (115.5) | |
In most cases, NW Natural also mitigates the credit risk of financial derivatives by having master netting arrangements with counterparties which provide for making or receiving net cash settlements. Transactions of the same type in the same currency that have settlement on the same day with a single counterparty are netted and a single payment is delivered or received depending on which party is due funds.
Additionally, NW Natural has master contracts in place with each derivative counterparty, most of which include provisions for posting or calling for collateral. Generally, NW Natural can obtain cash or marketable securities as collateral with one day’s notice. Various collateral management strategies are used to reduce liquidity risk. The collateral provisions vary by counterparty but are not expected to result in the significant posting of collateral, if any. NW Natural has performed stress tests on the gas portfolio and concluded the liquidity risk from collateral calls is not material. Derivative credit exposure is primarily with investment grade counterparties rated AA-/Aa3 or higher. Contracts are diversified by counterparty, industry, sector and country to reduce credit and liquidity risk.
At December 31, 2024, financial derivative commodity credit risk on a volumetric basis was geographically concentrated 17% in the United States and 83% in Canada, based on counterparties' location. At December 31, 2023, financial derivative commodity credit risk on a volumetric basis was geographically concentrated 24% in the United States and 76% in Canada with our counterparties.
Credit Exposure to Insurance Companies
Credit exposure to insurance companies for loss or damage claims could be material. NW Holdings and NW Natural regularly monitor the financial condition of insurance companies who provide general liability insurance policy coverage to NW Holdings, NW Natural, their predecessors, and their subsidiaries.
Weather Risk
NW Natural has a weather normalization mechanism in Oregon; however, it is exposed to weather risk primarily from NGD business operations. A large percentage of NGD margin is volume driven, and current rates are based on an assumption of average weather. NW Natural's weather normalization mechanism in Oregon is for residential and small commercial customers, which is intended to stabilize the recovery of NGD business fixed costs and reduce fluctuations in customers’ bills due to colder or warmer than average weather. Customers in Oregon are allowed to opt out of the weather normalization mechanism. As of December 31, 2024, approximately 7% of Oregon customers had opted out. In addition to the Oregon customers opting out, Washington customers account for approximately 12% of our total customer base and are not covered by weather normalization. The combination of Oregon and Washington customers not covered by a weather normalization mechanism is 18% of all customers. See "Results of Operations—Regulatory Matters—Rate Mechanisms—WARM" above.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Shareholders of Northwest Natural Holding Company
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of Northwest Natural Holding Company and its subsidiaries (the "Company") as of December 31, 2024 and 2023, and the related consolidated statements of comprehensive income (loss), of shareholders' equity and of cash flows for each of the three years in the period ended December 31, 2024, including the related notes and financial statement schedules listed in the accompanying index (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.
Basis for Opinions
The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matters
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Accounting for the Effects of Regulatory Matters
As described in Note 2 to the consolidated financial statements, there were $512.6 million of regulatory assets and $846.3 million of regulatory liabilities as of December 31, 2024. The Company’s principal business is to operate as a holding company for Northwest Natural Gas Company (“NW Natural”) and its other subsidiaries. NW Natural's principal business is the distribution of natural gas, which is regulated; the accounting records and practices of the regulated businesses conform to the requirements and uniform system of accounts prescribed by regulatory authorities. Customer rates are regulated and have approved cost-based rates which are intended to allow the Company to earn a return on invested capital. As disclosed by management, regulatory accounting requires management to account for deferred expenses (or deferred revenues) as regulatory assets (or regulatory liabilities) on the balance sheet. When the recovery of these regulatory assets from, or refund of regulatory liabilities to, customers is approved, management recognizes the expense or revenue on the income statement at the same time the adjustment to amounts is included in rates charged to customers.
The principal considerations for our determination that performing procedures relating to the Company’s accounting for the effects of regulatory matters is a critical audit matter are the high degree of auditor effort in performing procedures and evaluating audit evidence related to the recovery of regulatory assets and the settlement of regulatory liabilities.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Shareholder of Northwest Natural Gas Company:
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Northwest Natural Gas Company and its subsidiaries (the "Company") as of December 31, 2024 and 2023, and the related consolidated statements of comprehensive income (loss), of shareholder’s equity and of cash flows for each of the three years in the period ended December 31, 2024, including the related notes and financial statement schedule listed in the accompanying index (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024 in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matters
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Accounting for the Effects of Regulatory Matters
As described in Note 2 to the consolidated financial statements, there were $511.8 million of regulatory assets and $845.2 million of regulatory liabilities as of December 31, 2024. The Company’s principal business is the distribution of natural gas, which is regulated; the accounting records and practices of the regulated businesses conform to the requirements and uniform system of accounts prescribed by regulatory authorities. Customer rates are regulated and have approved cost-based rates which are intended to allow the Company to earn a return on invested capital. As disclosed by management, regulatory accounting requires management to account for deferred expenses (or deferred revenues) as regulatory assets (or regulatory liabilities) on the balance sheet. When the recovery of these regulatory assets from, or refund of regulatory liabilities to, customers is approved, management recognizes the expense or revenue on the income statement at the same time the adjustment to amounts is included in rates charged to customers.
The principal considerations for our determination that performing procedures relating to the Company’s accounting for the effects of regulatory matters is a critical audit matter are the high degree of auditor effort in performing audit procedures and evaluating audit evidence obtained related to the recovery of regulatory assets and the settlement of regulatory liabilities.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s assessment of rates cases and other proceedings, including the probability of recovery of regulatory assets and the settlement of regulatory liabilities and related accounting and disclosure impacts. These procedures also included, among others (i) evaluating the reasonableness of management’s assessment regarding the probability of recovery of regulatory assets and settlement of regulatory liabilities, (ii) evaluating the sufficiency of the disclosures in the consolidated financial statements,
and (iii) testing, on a sample basis, the regulatory assets and liabilities, including those subject to rate cases and other proceedings, by considering the provisions and formulas outlined in rate orders, other regulatory correspondence, and the application of relevant regulatory precedents.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. ORGANIZATION AND PRINCIPLES OF CONSOLIDATION
The accompanying consolidated financial statements represent the respective, consolidated financial results of NW Holdings and NW Natural and all respective companies that each registrant directly or indirectly controls, either through majority ownership or otherwise. This is a combined report of NW Holdings and NW Natural, which includes separate consolidated financial statements for each registrant.
NW Natural's regulated natural gas distribution activities are reported in the natural gas distribution (NGD) segment. The NGD segment is NW Natural's core operating business and serves residential, commercial, and industrial customers in Oregon and southwest Washington. The NGD segment is the only reportable segment for NW Holdings and NW Natural. All other activities, water, wastewater and water services businesses, and other investments are aggregated and reported as other at their respective registrant.
NW Holdings and NW Natural consolidate all entities in which they have a controlling financial interest. Investments in corporate joint ventures and partnerships that NW Holdings does not directly or indirectly control, and for which it is not the primary beneficiary, include NNG Financial's investment in Kelso-Beaver Pipeline and NWN Water's investment in Avion Water Company, Inc., which are accounted for under the equity method. See Note 13 for activity related to investments. NW Holdings and its direct and indirect subsidiaries are collectively referred to herein as NW Holdings, and NW Natural and its direct and indirect subsidiaries are collectively referred to herein as NW Natural. The consolidated financial statements of NW Holdings and NW Natural are presented after elimination of all intercompany balances and transactions.
Notes to the consolidated financial statements reflect the activity for both NW Holdings and NW Natural for all periods presented, unless otherwise noted. Certain reclassifications have been made to conform prior period information to the current presentation. The reclassifications did not have a material effect on our consolidated financial statements.
2. SIGNIFICANT ACCOUNTING POLICIES
Use of Estimates
The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect reported amounts in the consolidated financial statements and accompanying notes. Actual amounts could differ from those estimates, and changes would most likely be reported in future periods. Management believes the estimates and assumptions used are reasonable.
Industry Regulation
NW Holdings' principal business is to operate as a holding company for NW Natural and its other subsidiaries. NW Natural's principal business is the distribution of natural gas, which is regulated by the OPUC and WUTC. NW Natural also has natural gas storage services, which are regulated by the FERC, and to a certain extent by the OPUC and WUTC. Additionally, certain of NW Holdings' subsidiaries own water businesses, which are regulated by the public utility commission in the state in which the water utility is located, which is currently Oregon, Washington, Idaho, Texas and Arizona. Wastewater businesses, to the extent they are regulated, are generally regulated by the public utility commissions in the state in which the wastewater utility is located, which is currently Texas and Arizona. Accounting records and practices of the regulated businesses conform to the requirements and uniform system of accounts prescribed by these regulatory authorities in accordance with U.S. GAAP. The businesses in which customer rates are regulated have approved cost-based rates which are intended to allow such businesses to earn a reasonable return on invested capital.
In applying regulatory accounting principles, NW Holdings and NW Natural capitalize or defer certain costs and revenues as regulatory assets and liabilities pursuant to orders of the applicable state public utility commission, which provide for the recovery of revenues or expenses from, or refunds to, utility customers in future periods, including a return or a carrying charge in certain cases.
Amounts NW Natural deferred as regulatory assets and liabilities were as follows:

(1)Unrealized gains or losses on derivatives are non-cash items and therefore do not earn a rate of return or a carrying charge. These amounts are recoverable through natural gas distribution rates as part of the annual Purchased Gas Adjustment (PGA) mechanism when realized at settlement.
(2)Refer to the Environmental Cost Deferral and Recovery table in Note 17 for a description of environmental costs.
(3)This deferral represents the margin adjustment resulting from differences between actual and expected volumes.
(4)Balance represents deferred net periodic benefit costs as approved by the OPUC.
(5)Energy efficiency program for industrial sales customers in Oregon to provide assistance with reducing their gas usage.
(6)Balances consist of deferrals and amortizations under approved regulatory mechanisms and typically earn a rate of return or carrying charge.
(7)Balance represents excess deferred income tax benefits subject to regulatory flow-through. See Note 11.
(8)Estimated costs of removal on certain regulated properties are collected through rates. See "Accounting Policies—Plant, Property, and Accrued Asset Removal Costs" below.
The amortization period for NW Natural's regulatory assets and liabilities ranges from less than one year to an indeterminable period. Regulatory deferrals for gas costs payable are generally amortized over 12 months beginning each November 1 following the gas contract year during which the deferred gas costs are recorded. Similarly, most other regulatory deferred accounts are amortized over 12 months. However, certain regulatory account balances, such as income taxes, environmental costs, pension liabilities, and accrued asset removal costs, are large and tend to be amortized over longer periods once NW Natural has agreed upon an amortization period with the respective regulatory agency.
We believe all costs incurred and deferred at December 31, 2024 are prudent. All regulatory assets are reviewed annually for recoverability, or more often if circumstances warrant. If we should determine that all or a portion of these regulatory assets no longer meet the criteria for continued application of regulatory accounting, then NW Holdings and NW Natural would be required to write-off the net unrecoverable balances in the period such determination is made.
Regulatory interest income of $5.4 million and $6.5 million and regulatory interest expense of $4.0 million and $2.9 million was recognized within other income (expense), net for the years ended December 31, 2024 and 2023, respectively.
Environmental Regulatory Accounting
See Note 17 for information about the SRRM and OPUC orders regarding implementation.
New Accounting Standards
NW Natural and NW Holdings consider the applicability and impact of all accounting standards updates (ASUs) issued by the Financial Accounting Standards Board (FASB). ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on consolidated financial position or results of operations.
Recently Issued Accounting Pronouncements
JOINT VENTURE FORMATIONS. In August 2023, the FASB issued ASU 2023-05, which requires a joint venture to initially measure all contributions received upon its formation at fair value. The standard is effective for all joint venture entities with a formation date on or after January 1, 2025, with early adoption permitted. The adoption of this standard is not anticipated to have a material impact on our results of operations, liquidity or capital resources.
SEGMENT REPORTING. In November 2023, the FASB issued ASU 2023-07, which requires additional disclosures about significant segment expenses. The disclosures were required beginning with this annual report for the year ending December 31, 2024. The adoption of this standard did not have an impact on our results of operations, liquidity or capital resources. See Note 4.
IMPROVEMENTS TO INCOME TAX DISCLOSURES. In December 2023, the FASB issued ASU 2023-09, which requires additional disclosures about income taxes. The disclosures are required beginning with our annual report for the year ending December 31, 2025. The adoption of this standard is not anticipated to have an impact on our results of operations, liquidity or capital resources.
DISAGGREGATION OF EXPENSE DISCLOSURES. In November 2024, the FASB issued ASU 2024-03, which requires additional disclosures of disaggregated income statement expenses. The disclosures are required beginning with our annual report for the year ending December 31, 2027. The adoption of this standard is not anticipated to have an impact on our results of operations, liquidity, or capital resources.
Recent Securities and Exchange Commission (SEC) Final Rules
INSIDER TRADING ARRANGEMENTS. In December 2022, the SEC adopted the final rule under SEC Release No. 33-11138, Insider Trading Arrangements and Related Disclosures, which requires new disclosures regarding insider trading policies and procedures, the use of certain insider trading plans and director and executive compensation regarding equity compensation awards made close in time to disclosure of material nonpublic information. The policy was included as an exhibit to our annual report for the year ending December 31, 2024.

In March 2024, the SEC issued a final rule under SEC Release Nos. 33-11275 and 34-99678, The Enhancement and Standardization of Climate-Related Disclosures for Investors, which requires registrants to provide climate disclosures in their annual reports. Under the final rule, disclosures are required beginning with our annual report for the year ending December 31, 2025. In April 2024, the SEC voluntarily stayed implementation of the climate rule pending completion of judicial review of challenges to the rules consolidated in the Eighth Circuit Court of Appeals. We are currently evaluating the impact of this final rule on our disclosures.
Accounting Policies
The accounting policies discussed below apply to both NW Holdings and NW Natural.
Plant, Property, and Accrued Asset Removal Costs
Plant and property are stated at cost, including capitalized labor, materials, and overhead. In accordance with regulatory accounting standards, the cost of acquiring and constructing long-lived plant and property generally includes an allowance for funds used during construction (AFUDC) or capitalized interest. AFUDC represents the regulatory financing cost incurred when debt and equity funds are used for construction (see “AFUDC” below). When constructed assets are subject to market-based rates rather than cost-based rates, the financing costs incurred during construction are included in capitalized interest in accordance with U.S. GAAP, not as regulatory financing costs under AFUDC.
In accordance with long-standing regulatory treatment, our depreciation rates consist of three components: one based on the average service life of the asset, a second based on the estimated salvage value of the asset, and a third based on the asset’s estimated cost of removal. We collect, through rates, the estimated cost of removal on certain regulated properties through depreciation expense, with a corresponding offset to accumulated depreciation. These removal costs are non-legal obligations as defined by regulatory accounting guidance. Therefore, we have included these costs as non-current regulatory liabilities rather than as accumulated depreciation on our consolidated balance sheets. In the rate setting process, the liability for removal costs is treated as a reduction to the net rate base on which the NGD business has the opportunity to earn its allowed rate of return.
The costs of NGD plant retired or otherwise disposed of are removed from NGD plant and charged to accumulated depreciation for recovery or refund through future rates. Gains from the sale of regulated assets are generally deferred and refunded to customers. For assets not related to NGD, we record a gain or loss upon the disposal of the property, and the gain or loss is recorded in operating income or loss in the consolidated statements of comprehensive income.
The provision for depreciation of NGD property, plant, and equipment is recorded under the group method on a straight-line basis with rates computed in accordance with depreciation studies approved by regulatory authorities. The weighted-average depreciation rate for NGD assets in service was approximately 2.9% for 2024, and 3.0% for 2023 and 2022, reflecting the approximate weighted-average economic life of the property. This includes 2024 weighted-average depreciation rates for the
following asset categories: 2.5% for transmission and distribution plant, 2.3% for gas storage facilities, 4.7% for general plant, and 6.1% for intangible and other fixed assets.
AFUDC. Certain additions to NGD and water plant include AFUDC, which represents the net cost of debt and equity funds used during construction. AFUDC is calculated using actual interest rates for debt and authorized rates for ROE, if applicable. If short-term debt balances are less than the total balance of construction work in progress, then a composite AFUDC rate is used to represent interest on all debt funds, shown as a reduction to interest charges, and on ROE funds, shown as other income. While cash is not immediately recognized from recording AFUDC, it is realized in future years through rate recovery resulting from the higher cost of service. Our NGD composite AFUDC rate was 6.4% in 2024, 7.5% in 2023, and 2.8% in 2022.
IMPAIRMENT OF LONG-LIVED ASSETS. We review the carrying value of long-lived assets whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable. Factors that would necessitate an impairment assessment of long-lived assets include a significant adverse change in the extent or manner in which the asset is used, a significant adverse change in legal factors or business climate that could affect the value of the asset, or a significant decline in the observable market value or expected future cash flows of the asset, among others.
When such factors are present, we assess the recoverability by determining whether the carrying value of the asset will be recovered through expected future cash flows. An asset is determined to be impaired when the carrying value of the asset exceeds the expected undiscounted future cash flows from the use and eventual disposition of the asset. If an impairment is indicated, we record an impairment loss for the difference between the carrying value and the fair value of the long-lived assets. Fair value is estimated using appropriate valuation methodologies, which may include an estimate of discounted cash flows.
Cash and Cash Equivalents
Cash and cash equivalents include cash on hand plus highly liquid investment accounts with original maturity dates of three months or less. These investments are readily convertible to cash with fair value approximating cost.
At December 31, 2024, NW Holdings had outstanding checks of $3.9 million, substantially all of which is recorded at NW Natural, and at December 31, 2023, NW Holdings had $7.5 million of outstanding checks. These balances are included in accounts payable in the NW Holdings and NW Natural balance sheets.
Restricted Cash
Restricted cash is primarily comprised of funds from public purpose charges for programs that assist low-income customers with bill payments or energy efficiency. These balances are included in other current assets in the NW Holdings and NW Natural balance sheets.
The following table provides a reconciliation of the cash, cash equivalents and restricted cash balances at NW Holdings as of December 31, 2024 and 2023:

| Cash, cash equivalents and restricted cash | | $ | 29,428 | | | $ | 36,520 | |
Revenue Recognition and Accrued Unbilled Revenue
Revenues, derived primarily from the sale and transportation of natural gas, are recognized upon delivery of gas or water, or service to customers. Revenues include accruals for gas or water delivered but not yet billed to customers based on estimates of deliveries from meter reading dates to month end (accrued unbilled revenue). Accrued unbilled revenue is dependent upon a number of factors that require management’s judgment, including total natural gas receipts and deliveries, customer use of natural gas or water by billing cycle, and weather factors. Accrued unbilled revenue is reversed the following month when actual billings occur. NW Holdings' accrued unbilled revenue at December 31, 2024 and 2023 was $94.4 million and $83.1 million, respectively, substantially all of which is accrued unbilled revenue at NW Natural.
Revenues not related to NGD are derived primarily from Interstate Storage Services, asset management activities at the Mist gas storage facility, and other investments and business activities. At the Mist underground storage facility, revenues are primarily firm service revenues in the form of fixed monthly reservation charges. In addition, we also have asset management service revenue from an independent energy marketing company that optimizes commodity, storage, and pipeline capacity release transactions. Under this agreement, guaranteed asset management revenue is recognized using a straight-line, pro-rata methodology over the term of each contract. Revenues earned above the guaranteed amount are recognized as they are earned.
Revenue Taxes
Revenue-based taxes are primarily franchise taxes, which are collected from customers and remitted to taxing authorities. Revenue taxes are included in operating expenses in the statements of comprehensive income for NW Holdings and NW Natural. Revenue taxes at NW Holdings were $48.3 million, $48.7 million, and $41.8 million for 2024, 2023, and 2022, respectively.
Accounts Receivable and Allowance for Uncollectible Accounts
Accounts receivable consist primarily of amounts due for natural gas sales and transportation services to NGD customers, plus amounts due for gas storage services. NW Holdings and NW Natural establish allowances for uncollectible accounts (allowance) for trade receivables, including accrued unbilled revenue, based on the aging of receivables, collection experience of past due account balances including payment plans, and historical trends of write-offs as a percent of revenues. A specific allowance is established and recorded for large individual customer receivables when amounts are identified as unlikely to be partially or fully recovered. Inactive accounts are written-off against the allowance after they are 120 days past due or when deemed uncollectible. Differences between the estimated allowance and actual write-offs will occur based on a number of factors, including changes in economic conditions, customer creditworthiness, and natural gas prices. The allowance for uncollectible accounts is adjusted quarterly, as necessary, based on information currently available.
ALLOWANCE FOR TRADE RECEIVABLES. The payment term of our NGD receivables is generally 15 days. For these short-term receivables, it is not expected that forecasted economic conditions would significantly affect the loss estimates under stable economic conditions. For extreme situations like a financial crisis, natural disaster, and the economic slowdown caused by the COVID-19 pandemic, we enhanced our review and analysis.
For the residential and commercial uncollectible provision, we primarily followed our standard methodology, which includes assessing historical write-off trends and current information on delinquent accounts. Beginning October 1, 2022, new collection rules from the OPUC applied to residential and commercial customers. This included enhanced protections for low-income customers, a return to pre-pandemic time payment arrangements terms, revised disconnection rules during the heating season, and other items. As a result of these Oregon rule changes and our recent collection process experience, we augmented our provision review for accounts in the following categories: closed or inactive accounts aged less than 120 days, accounts on payment plans, and all other open accounts not on payment plans. For industrial accounts, we continue to assess the provision on an account-by-account basis with specific reserves taken as necessary. NW Natural will continue to closely monitor and evaluate our accounts receivable and the provision for uncollectible accounts.
The following table presents the activity related to the NW Holdings provision for uncollectible accounts by pool, substantially all of which is related to NW Natural's accounts receivable:
| | | | | | | | | | | | | | | | | | | | | | | |

| Total NW Holdings | $ | 3,455 | | | $ | 2,283 | | | $ | (2,264) | | | $ | 3,474 | |
ALLOWANCE FOR NET INVESTMENTS IN SALES-TYPE LEASES. NW Natural currently holds two net investments in sales-type leases, with substantially all of the net investment balance related to the North Mist natural gas storage agreement with Portland General Electric (PGE) which is billed under an OPUC-approved rate schedule. See Note 7 for more information on the North Mist lease. Due to the nature of this service, PGE may recover the costs of the lease through general rate cases. Therefore, we expect the risk of loss due to the credit of this lessee to be remote. As such, no allowance for uncollectibility was recorded for our
sales-type lease receivables. NW Natural will continue monitoring the credit health of the lessees and the overall economic environment, including the economic factors closely tied to the financial health of our current and future lessees.
Inventories
NGD gas inventories, which consist of natural gas in storage for NGD customers, are stated at the lower of weighted-average cost or net realizable value. The regulatory treatment of these inventories provides for cost recovery in customer rates. NGD gas inventories injected into storage are priced in inventory based on actual purchase costs, and those withdrawn from storage are charged to cost of gas during the period they are withdrawn at the weighted-average inventory cost.
Gas storage inventories mainly consist of natural gas received as fuel-in-kind from storage customers. Gas storage inventories are valued at the lower of average cost or net realizable value. Cushion gas is not included in inventory balances, is recorded at original cost, and is classified as a long-term plant asset.
Materials and supplies inventories consist of inventories both related to and unrelated to NGD and are stated at the lower of average cost or net realizable value.
NW Natural's NGD and gas storage inventories totaled $37.9 million and $47.2 million at December 31, 2024 and 2023, respectively. At December 31, 2024 and 2023, NW Holdings' materials and supplies inventories, which are comprised primarily of NW Natural's materials and supplies, totaled $24.8 million and $25.6 million, respectively.
During 2024 and 2023, NW Natural entered into certain agreements to purchase renewable thermal certificates (RTCs). RTCs are initially recorded at cost and subsequently assessed for impairment based on the lower-of-cost or market model. NW Natural's RTCs inventory totaled $0.4 million and $0.5 million at December 31, 2024 and 2023, respectively.
Greenhouse Gas Allowances
WASHINGTON. NW Natural is subject to greenhouse gas (GHG) emission reduction requirements under the Washington Climate Commitment Act (CCA) regulations. Under Washington's CCA, emission reduction compliance mechanisms include: 1) allowances distributed at no cost by the state, 2) purchasing allowances at state-run auctions or secondary markets, 3) purchasing carbon offsets, and 4) supplying alternative gaseous fuels, such as renewable natural gas and hydrogen.
NW Natural will account for all purchased Washington allowances as inventory at the lower of cost or market. Any compliance instruments or allowances that are acquired through government allocations at no cost will be accounted for as inventory at no cost. As of December 31, 2024 and 2023, NW Natural had $43.9 million and $39.3 million of emissions allowances for compliance in Washington recorded as inventory, respectively.
The CCA allows for the sale of compliance instruments or allowances, and as a result, should NW Natural sell these it will recognize revenue when title to the instrument or allowance is transferred to a counterparty, and NW Natural will recognize expense at the time of recognition of the related sale. During the years ended December 31, 2024 and 2023 NW Natural consigned no-cost allowances to Washington auctions and received $8.5 million and $17.1 million, respectively, in cash, which proceeds were recorded as a regulatory liability for the benefit of customers.
We measure the compliance obligation, which is based on emissions, at the carrying value of inventory held plus the fair value of any additional emission allowances NW Natural would need to purchase to satisfy the obligations. Under the Washington program, NW Natural recognized a liability of $29.9 million and $19.9 million as of December 31, 2024 and 2023, respectively. A portion of the costs to comply with the Washington program are currently being recovered from utility customers through rates beginning January 1, 2024. NW Natural recognized $29.9 million and $20.5 million of deferred costs as of December 31, 2024 and 2023, respectively.
OREGON. In November 2024, the Environmental Quality Commission adopted the Climate Protection Program (CPP). The CPP sets enforceable and declining limits, or caps, on GHG emissions from fossil fuels used throughout Oregon. The first compliance period starts January 1, 2025 and covers emissions through the end of 2027.
Gas Reserves
Gas reserves are payments to acquire and produce natural gas reserves. Gas reserves are stated at cost, adjusted for regulatory amortization, with the associated deferred tax benefits recorded as liabilities on the balance sheet. The current portion is calculated based on expected gas deliveries within the next fiscal year. NW Natural recognizes regulatory amortization of this asset on a volumetric basis calculated using the estimated gas reserves and the estimated therms extracted and sold each month. The amortization of gas reserves is recorded to cost of gas along with gas production revenues and production costs. See Note 13.
Derivatives
NW Natural's derivatives are measured at fair value and recognized as either assets or liabilities on the balance sheet. Changes in the fair value of the derivatives are recognized in earnings unless specific regulatory or hedge accounting criteria are met. Accounting for derivatives and hedges provides an exception for contracts intended for normal purchases and normal sales for
which physical delivery is probable. In addition, certain derivative contracts are approved by regulatory authorities for recovery or refund through customer rates. Accordingly, the changes in fair value of these approved contracts are deferred as regulatory assets or liabilities pursuant to regulatory accounting principles. NW Natural's financial derivatives generally qualify for deferral under regulatory accounting.
Derivative contracts entered into for NGD requirements after the annual PGA rate has been set and transacted during the PGA year are subject to the PGA incentive sharing mechanism. In Oregon, NW Natural participates in a PGA sharing mechanism under which it is required to select either an 80% or 90% deferral of higher or lower gas costs such that the impact on current earnings from the gas cost sharing is either 20% or 10% of gas cost differences compared to PGA prices, respectively. For each of the PGA years in Oregon beginning November 1, 2024, 2023, and 2022, NW Natural selected the 90% deferral of gas cost differences. In Washington, 100% of the differences between the PGA prices and actual gas costs are deferred. See Note 15.
NW Holdings and NW Natural have financial derivative policies that set forth guidelines for using selected derivative products to support prudent risk management strategies within designated parameters. NW Natural's objective for using derivatives is to decrease the volatility of gas prices, interest rates, foreign currency, and cash flows without speculative risk. The use of derivatives is permitted only after the risk exposures have been identified, are determined to exceed acceptable tolerance levels, and are determined necessary to support normal business activities. NW Natural does not enter into derivative instruments for trading purposes. All commodity and foreign exchange derivatives are currently held at NW Natural, and an interest rate swap is held at NWN Water.
Fair Value
In accordance with fair value accounting, we use the following fair value hierarchy for determining inputs for our debt, pension plan assets, and derivative fair value measurements:
•Level 1: Valuation is based on quoted prices for identical instruments traded in active markets;
•Level 2: Valuation is based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market; and
•Level 3: Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect our own estimates of assumptions market participants would use in valuing the asset or liability.
In addition, the fair value for certain pension trust investments is determined using Net Asset Value per share (NAV) as a practical expedient, and therefore they are not classified within the fair value hierarchy. These investments primarily consist of institutional commingled funds.
When developing fair value measurements, it is our policy to use quoted market prices whenever available or to maximize the use of observable inputs and minimize the use of unobservable inputs when quoted market prices are not available. Fair values are primarily developed using industry-standard models that consider various inputs including: (a) quoted future prices for commodities; (b) forward currency prices; (c) time value; (d) volatility factors; (e) current market and contractual prices for underlying instruments; (f) market interest rates and yield curves; (g) credit spreads; and (h) other relevant economic measures. NW Natural considers liquid points for natural gas hedging to be those points for which there are regularly published prices in a nationally recognized publication or where the instruments are traded on an exchange.
Goodwill and Business Combinations
NW Holdings, through its wholly-owned subsidiary NWN Water and NWN Water's wholly-owned subsidiaries, has completed various acquisitions that resulted in the recognition of goodwill. Goodwill is measured as the excess of the acquisition-date fair value of the consideration transferred over the acquisition-date fair value of the net identifiable assets assumed. Adjustments are recorded during the measurement period to finalize the allocation of the purchase price. The carrying value of goodwill is reviewed annually during the fourth quarter, or whenever events or changes in circumstance indicate that such carrying values may not be recoverable. The goodwill assessment policy begins with a qualitative analysis in which events and circumstances are evaluated, including macroeconomic conditions, industry and market conditions, regulatory environments, and overall financial performance of the reporting unit. If the qualitative assessment indicates that the carrying value may be at risk of recoverability, a quantitative evaluation is performed to measure the carrying value of the goodwill against the fair value of the reporting unit. The reporting unit is determined primarily based on current operating segments and the level of review provided by the Chief Operating Decision Maker (CODM) and/or segment management on the operating segment's financial results. Reporting units are evaluated periodically for changes in the corporate environment.
As of December 31, 2024 and 2023, NW Holdings had goodwill of $183.8 million and $163.3 million, respectively. All of NW Holdings' goodwill was acquired through the business combinations completed by NWN Water and its wholly-owned subsidiaries. No impairment charges were recorded as a result of the fourth quarter goodwill impairment assessment.
Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the aggregate of the consideration transferred, measured at fair value at the acquisition date, and the fair value of any non-controlling interest in the acquiree. Acquisition-related costs are expensed as incurred. When NW Natural acquires a business, it assesses the financial assets acquired and liabilities assumed for appropriate classification and designation in accordance with the contractual
terms, economic circumstances and pertinent conditions as of the acquisition date. When there is substantial judgment or uncertainty around the fair value of acquired assets, we may engage a third party expert to assist in determining the fair values of certain assets or liabilities.
Income Taxes
We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the enactment date period unless, for NW Natural, a regulatory order specifies deferral of the effect of the change in tax rates over a longer period of time.
For NW Natural, deferred income tax assets and liabilities are also recognized for temporary differences where the deferred income tax benefits or expenses have previously been flowed through in the ratemaking process of the NGD business. Regulatory tax assets and liabilities are recorded on these deferred tax assets and liabilities to the extent it is believed they will be recoverable from or refunded to customers in future rates.
Investment tax credits associated with rate regulated plant additions are deferred for financial statement purposes and amortized over the estimated useful lives of the related plant.
NW Holdings files consolidated or combined income tax returns that include NW Natural. Income tax expense is allocated on a separate company basis incorporating certain consolidated return considerations. Subsidiary income taxes payable or receivable are generally settled with NW Holdings, the common agent for income tax matters.
Interest and penalties related to unrecognized tax benefits, if any, are recognized within income tax expense and accrued interest and penalties are recognized within the related tax liability line in the consolidated balance sheets. No accrued interest or penalties for uncertain tax benefits have been recorded. See Note 11.
Environmental Contingencies
Loss contingencies are recorded as liabilities when it is probable a liability has been incurred and the amount of the loss is reasonably estimable in accordance with accounting standards for contingencies. Estimating probable losses requires an analysis of uncertainties that often depend upon judgments about potential actions by third parties. Accruals for loss contingencies are recorded based on an analysis of potential results.
With respect to environmental liabilities and related costs, estimates are developed based on a review of information available from numerous sources, including completed studies and site specific negotiations. NW Natural's policy is to accrue the full amount of such liability when information is sufficient to reasonably estimate the amount of probable liability. When information is not available to reasonably estimate the probable liability, or when only the range of probable liabilities can be estimated and no amount within the range is more likely than another, it is our policy to accrue at the low end of the range. Accordingly, due to numerous uncertainties surrounding the course of environmental remediation and the preliminary nature of several site investigations, in some cases, it may not be possible to reasonably estimate the high end of the range of possible loss. In those cases, the nature of the potential loss and the fact that the high end of the range cannot be reasonably estimated is disclosed. See Note 17.
Unconsolidated Affiliates
NWN Water has an equity interest in a business which we account for under the equity method as we do not exercise control of the major operating and financial policies. The business transactions with our equity method investment are not significant. We regularly assess the profitability and valuation of our investment for any potential impairment. See Note 13.
Cloud Computing Arrangements
Implementation costs associated with its cloud computing arrangements are capitalized consistent with costs capitalized for internal-use software. Capitalized implementation costs are included in other assets in the consolidated balance sheets. The implementation costs are amortized over the term of the related hosting agreement, including renewal periods that are reasonably certain to be exercised. Amortization expense of implementation costs are recorded as operations and maintenance expenses in the consolidated statements of comprehensive income. The implementation costs are included within operating activities in the consolidated statements of cash flows.
Subsequent Events
We monitor significant events occurring after the balance sheet date and prior to the issuance of the financial statements to determine the impacts, if any, of events on the financial statements to be issued. See Note 18.
3. EARNINGS PER SHARE
Basic earnings or loss per share are computed using NW Holdings' net income or loss and the weighted average number of common shares outstanding for each period presented. Diluted earnings per share are computed in the same manner, except using the weighted average number of common shares outstanding plus the effects of the assumed exercise of stock options and the payment of estimated stock awards from other stock-based compensation plans that are outstanding at the end of each period presented. Anti-dilutive stock awards are excluded from the calculation of diluted earnings or loss per common share.
NW Holdings' diluted earnings or loss per share are calculated as follows:

4. SEGMENT INFORMATION
We primarily operate in one reportable business segment, which is NW Natural's local gas distribution business and is referred to as the NGD segment. NW Natural and NW Holdings also have investments and business activities not specifically related to the NGD segment, which are aggregated and reported as other and described below for each entity.
No individual customer accounts for over 10% of NW Holdings' or NW Natural's operating revenues.
Natural Gas Distribution
NW Natural's local gas distribution segment (NGD) is a regulated utility principally engaged in the purchase, sale, and delivery of natural gas and related services to customers in Oregon and southwest Washington. The NGD business is responsible for building and maintaining a safe and reliable pipeline distribution system, purchasing sufficient gas supplies from producers and marketers, contracting for firm and interruptible transportation of gas over interstate pipelines to bring gas from the supply basins into its service territory, and re-selling the gas to customers subject to rates, terms, and conditions approved by the OPUC or WUTC. NGD also includes taking customer-owned gas and transporting it from interstate pipeline connections, or city gates, to the customers’ end-use facilities for a fee, which is approved by the OPUC or WUTC. Approximately 88% of NGD customers are located in Oregon and 12% in Washington. On an annual basis, residential and commercial customers typically account for around 60% of total NGD volumes delivered and around 90% of NGD margin. Industrial customers largely account for the remaining volumes and NGD margin. A small amount of the margin is also derived from miscellaneous services, gains or losses from an incentive gas cost sharing mechanism, and other service fees.
Industrial sectors served by the NGD business include: pulp, paper, and other forest products; the manufacture of electronic, electrochemical and electrometallurgical products; the processing of farm and food products; the production of various mineral products; metal fabrication and casting; the production of machine tools, machinery, and textiles; the manufacture of asphalt, concrete, and rubber; printing and publishing; nurseries; and government and educational institutions.
In addition to NW Natural's local gas distribution business, the NGD segment also includes the portion of the Mist underground storage facility used to serve NGD customers, North Mist gas storage, NWN Gas Reserves, which is a wholly-owned subsidiary of Energy Corp, and NW Natural RNG Holding Company, LLC, a holding company established to invest in the development and procurement of regulated renewable natural gas for NW Natural.
NW Natural
NW Natural's activities in Other include Interstate Storage Services and third-party asset management services for the Mist facility in Oregon, appliance retail center operations, and corporate operating and non-operating revenues and expenses that cannot be allocated to NGD operations.
Earnings from Interstate Storage Services assets are primarily related to firm storage capacity revenues. Earnings from the Mist facility also include revenue, net of amounts shared with NGD customers, from management of NGD assets at Mist and upstream pipeline capacity when not needed to serve NGD customers. Under the Oregon sharing mechanism, NW Natural retains 80% of the pre-tax income from these services when the costs of the capacity were not included in NGD rates, or 10% of
the pre-tax income when the costs have been included in these rates. The remaining 20% and 90%, respectively, are recorded to a deferred regulatory account for crediting back to NGD customers.
NW Holdings
NW Holdings' activities in Other include all remaining activities not associated with NW Natural, specifically NWN Water, which consolidates the water and wastewater utility operations and water services businesses; NWN Water's equity investment in Avion Water Company, Inc.; NWN Gas Storage, a wholly-owned subsidiary of NWN Energy; other pipeline assets in NNG Financial; and NW Natural Renewables Holdings, LLC and its non-regulated renewable natural gas activities. Other also includes corporate revenues and expenses that cannot be allocated to other operations, including certain business development activities.

(1) Income (loss) from operations is not a financial measure used by the CODM, but is included in the table above to enable the reconciliation of NGD margin to consolidated income before taxes in accordance with ASU 2023-07.
Natural Gas Distribution Margin
NGD margin is the primary financial measure used by the CODM, consisting of NGD operating revenues, reduced by the associated cost of gas, environmental remediation expense, and revenue taxes. The cost of gas purchased for NGD customers is generally a pass-through cost in the amount of revenues billed to regulated NGD customers. Environmental remediation expense represents collections received from customers through environmental recovery mechanisms in Oregon and Washington as well as adjustments for the Oregon environmental earnings test when applicable. This is offset by environmental remediation expense presented in operating expenses. Revenue taxes are collected from NGD customers and remitted to taxing authorities. The collections from customers are offset by the expense recognition of the obligation to the taxing authority. By subtracting cost of gas, environmental remediation expense, and revenue taxes from NGD operating revenues, NGD margin provides a key metric used by the CODM in assessing the performance of the NGD segment.
NW Holdings and NW Natural's CODM is the chief executive officer. The CODM uses NGD margin to allocate resources predominantly in the annual budget and forecasting process. The CODM considers budget-to-actual variances on a monthly basis when making decisions about allocating capital and personnel. The CODM also uses NGD margin to assess the performance of NGD.

5. COMMON STOCK
As of December 31, 2024 and 2023, NW Holdings had 100 million shares of common stock authorized. As of December 31, 2024, NW Holdings had 260,935 shares reserved for issuance of common stock under the Employee Stock Purchase Plan (ESPP) and 250,460 shares reserved for issuance under the Dividend Reinvestment and Direct Stock Purchase Plan (DRPP). At NW Holdings' election, shares sold through the DRPP may be purchased in the open market or through original issuance of shares reserved for issuance under the DRPP.
In August 2021, NW Holdings initiated an at-the-market (ATM) equity program by entering into an equity distribution agreement under which NW Holdings issued and sold from time to time shares of common stock, no par value, having an aggregate gross sales price of up to $200 million. In August 2024, the Finance Committee of the NW Holdings' Board of Directors authorized NW Holdings' sale of an additional $200 million in the aggregate gross sales price under the ATM equity program, with the result that a total of $400 million in the aggregate gross sales price has been authorized for issuance and sale under the ATM equity program. NW Holdings is under no obligation to offer and sell common stock under the ATM equity program, which the Finance Committee of the NW Holdings' Board of Directors has authorized through August 2027. Any shares of common stock offered under the ATM equity program are registered on NW Holdings’ universal shelf registration statement filed with the SEC, which expires in August 2027, or will be registered on a subsequent registration statement to be filed by NW Holdings.
During the year ended December 31, 2024, NW Holdings issued and sold 2,382,750 shares of common stock pursuant to the ATM equity program resulting in cash proceeds of $90.3 million, net of fees and commissions paid to agents of $1.6 million. As of December 31, 2024, NW Holdings had $151.6 million of equity available for issuance under the program. The ATM equity program was initiated to raise funds for general corporate purposes, including equity contributions to NW Holdings’ subsidiaries, NW Natural and NW Natural Water. Contributions to NW Natural and NW Natural Water will be used for general corporate purposes.
Stock Repurchase Program
Effective May 23, 2024, NW Holdings’ Board authorized a new share repurchase program under which NW Holdings may repurchase in open market or privately negotiated transactions up to an aggregate of 5.0 million shares or an amount not to exceed $150 million. The new share repurchase program is authorized to continue until the program is used, terminated or replaced. The repurchase program replaces the Company’s previously authorized share repurchase program, which commenced in 2000 and authorized the repurchase of up to 2.8 million shares, or an amount not to exceed $100 million, in the aggregate. No shares of common stock were repurchased pursuant to our new program or prior program during the year ended December 31, 2024. Since the previous plan’s inception in 2000 under NW Natural, a total of 2.1 million shares have been repurchased at a total cost of $83.3 million.

NW Natural's revenue represents substantially all of NW Holdings' revenue and is recognized for both registrants when the obligation to customers is satisfied and in the amount expected to be received in exchange for transferring goods or providing services. Revenue from contracts with customers contains one performance obligation that is generally satisfied over time, using the output method based on time elapsed, due to the continuous nature of the service provided. The transaction price is determined by a set price agreed upon in the contract or dependent on regulatory tariffs. Customer accounts are settled on a monthly basis or paid at time of sale and based on historical experience. It is probable that we will collect substantially all of the consideration to which we are entitled. We evaluated the probability of collection in accordance with the current expected credit losses standard.
NW Holdings and NW Natural do not have any material contract assets, as net accounts receivable and accrued unbilled revenue balances are unconditional and only involve the passage of time until such balances are billed and collected. NW Holdings and NW Natural do not have any material contract liabilities.
Revenue taxes are included in operating revenues with an equal and offsetting expense recognized in operating expenses in the consolidated statements of comprehensive income. Revenue-based taxes are primarily franchise taxes, which are collected from NGD customers and remitted to taxing authorities.
Natural Gas Distribution
Natural Gas Sales
NW Natural's primary source of revenue is providing natural gas to customers in the NGD service territory, which includes residential, commercial, industrial and transportation customers. NGD revenue is generally recognized over time upon delivery of the gas commodity or service to the customer, and the amount of consideration received and recognized as revenue is dependent on the Oregon and Washington tariffs. There is no right of return or warranty for services provided. Revenues include firm and interruptible sales and transportation services, franchise taxes recovered from the customer, late payment fees, service fees, and accruals for gas delivered but not yet billed (accrued unbilled revenue). The accrued unbilled revenue balance is based on estimates of deliveries during the period from the last meter reading and management judgment is required for a number of factors used in this calculation, including customer use and weather factors.
Customer accounts are to be paid in full each month and as such, there is no significant financing component for this source of revenue. Due to the election of the right to invoice practical expedient, we do not disclose the value of unsatisfied performance obligations.
Alternative Revenue
Weather normalization (WARM) and decoupling mechanisms are considered to be alternative revenue programs. Alternative revenue programs are considered to be contracts between NW Natural and its regulator and are excluded from revenue from contracts with customers.
Leasing Revenue
Leasing revenue primarily consists of revenues from NW Natural's North Mist Storage contract with Portland General Electric (PGE) in support of PGE's gas-fired electric power generation facilities under an initial 30-year contract with options to extend, totaling up to an additional 50 years upon mutual agreement of the parties. The facility is accounted for as a sales-type lease with regulatory accounting deferral treatment. The investment is included in rate base under an established cost-of-service tariff schedule, with revenues recognized according to the tariff schedule and as such, profit upon commencement was deferred and will be amortized over the lease term. Leasing revenue also contains rental revenue from small leases of property owned by NW Natural to third parties. The majority of these transactions are accounted for as operating leases and the revenue is recognized over the term of the lease agreement. Lease revenue is excluded from revenue from contracts with customers. See Note 7 for additional information.
NW Natural Other
Gas Storage Revenue
NW Natural's other revenue includes gas storage activity, which includes Interstate Storage Services used to store natural gas for customers. Gas storage revenue is generally recognized over time as the gas storage service is provided to the customer and the amount of consideration received and recognized as revenue is dependent on set rates defined per the storage agreements. Noncash consideration in the form of dekatherms of natural gas is received as consideration for providing gas injection services to gas storage customers. This noncash consideration is measured at fair value using the average spot rate. Customer accounts are generally paid in full each month, and there is no right of return or warranty for services provided. Revenues include firm and interruptible storage services, net of the profit sharing amount refunded to NGD customers.
Asset Management Revenue
Revenues include the optimization of storage assets and pipeline capacity by a third party and are provided net of the profit sharing amount refunded to NGD customers. Certain asset management revenues received are recognized over time using a straight-line approach over the term of each contract, and the amount of consideration received and recognized as revenue is dependent on a variable pricing model. Variable revenues earned above guaranteed amounts are estimated and recognized at the end of each period using the most likely amount approach. Additionally, other asset management revenues may be based on a fixed rate. Generally, asset management accounts are settled on a monthly basis.
As of December 31, 2024, unrecognized revenue for the fixed component of the transaction price related to gas storage and asset management revenue was approximately $113.4 million. Of this amount, approximately $22.6 million will be recognized in 2025, $16.1 million in 2026, $15.3 million in 2027, $13.9 million in 2028, $13.9 million in 2029 and $31.6 million thereafter. The amounts presented here are calculated using current contracted rates.
Appliance Retail Center Revenue
NW Natural owns and operates an appliance store that is open to the public, where customers can purchase natural gas home appliances. Revenue from the sale of appliances is recognized at the point in time in which the appliance is transferred to the third party responsible for delivery and installation services and when the customer has legal title to the appliance. It is required that the sale be paid for in full prior to transfer of legal title. The amount of consideration received and recognized as revenue varies with changes in marketing incentives and discounts offered to customers.
NW Holdings Other
Water and Wastewater Services
NW Natural Water provides water and wastewater services to customers. Water and wastewater service revenue is generally recognized over time upon delivery of the water commodity or service to the customer, and the amount of consideration received and recognized as revenue is dependent on the tariffs established in the states where we operate. There is no right of return or warranty for services provided.
Customer accounts are to be paid in full each month, bi-monthly, or quarterly and as such, there is no significant financing component for this source of revenue. Due to the election of the right to invoice practical expedient, we do not disclose the value of unsatisfied performance obligations.
Renewable Natural Gas Sales
NW Natural Renewables is an unregulated subsidiary of NW Holdings established to pursue investments in renewable natural gas (RNG) activities. NW Natural Renewables' primary source of revenue is from the sale of RNG under long-term contracts. RNG revenue is generally recognized over time upon delivery of the gas commodity to the customer at the designated delivery point and the amount of consideration received and recognized as revenue is dependent on a variable pricing model defined per the contract. Customer accounts are to be paid in full each month and as such, there is no significant financing component for this source of revenue. Due to the election of the right to invoice practical expedient, we do not disclose the value of unsatisfied performance obligations.
7. LEASES
Lease Revenue
Leasing revenue primarily consists of NW Natural's North Mist natural gas storage agreement with PGE which is billed under an OPUC-approved rate schedule and includes an initial 30-year term beginning May 2019 with options to extend, totaling up to an additional 50 years upon mutual agreement of the parties. Under U.S. GAAP, this agreement is classified as a sales-type lease and qualifies for regulatory accounting deferral treatment. The investment in the storage facility is included in rate base under a separately established cost-of-service tariff, with revenues recognized according to the tariff schedule. As such, the selling profit that was calculated upon commencement as part of the sale-type lease recognition was deferred and will be amortized over the lease term. Billing rates under the cost-of-service tariff will be updated annually to reflect current information including depreciable asset levels, forecasted operating expenses, and the results of regulatory proceedings, as applicable, and revenue received under this agreement is recognized as operating revenue on the consolidated statements of comprehensive income. There are no variable payments or residual value guarantees. The lease does not contain an option to purchase the underlying
assets.
NW Natural also maintains a sales-type lease for specialized compressor facilities to provide high pressure compressed natural gas (CNG) services. Lease payments are outlined in an OPUC-approved rate schedule over a 10-year term. There are no variable payments or residual value guarantees. The selling profit computed upon lease commencement was not significant.
Our lessor portfolio also contains small leases of property owned by NW Natural to third parties. These transactions are accounted for as operating leases and the revenue is recognized over the term of the lease agreement.
The components of lease revenue at NW Natural were as follows:

Additionally, lease revenue of $0.6 million was recognized for each of the years ended December 31, 2024, 2023, and 2022, respectively, related to operating leases associated with non-utility property rentals. Lease revenue related to these leases was presented in other income (expense), net on the consolidated statements of comprehensive income as it is non-operating income.

The total leases receivable above is reported under the NGD segment and the short- and long-term portions are included within other current assets and assets under sales-type leases on the consolidated balance sheets, respectively. The total amount of unguaranteed residual assets was $6.0 million and $5.5 million at December 31, 2024 and 2023, respectively, and is included in assets under sales-type leases on the consolidated balance sheets. Additionally, under regulatory accounting, the revenues and
expenses associated with these agreements are presented on the consolidated statements of comprehensive income such that their presentation aligns with similar regulated activities at NW Natural.
Lease Expense
Operating Leases
We have operating leases for land, buildings and equipment. Our primary lease is for NW Natural's headquarters and operations center. Our leases have remaining lease terms of three months to 15 years. Many of our lease agreements include options to extend the lease, which we do not include in our minimum lease terms unless they are reasonably certain to be exercised. Short-term leases with a term of 12 months or less are not recorded on the balance sheet.
As most of our leases do not provide an implicit rate and are entered into by NW Natural, we use an estimated discount rate representing the rate we would have incurred to finance the funds necessary to purchase the leased asset and is based on information available at the lease commencement date in determining the present value of lease payments.

Headquarters and Operations Center Lease
NW Natural commenced a 20-year operating lease agreement in March 2020 for a new headquarters and operations center in Portland, Oregon. There is an option to extend the term of the lease for two additional periods of seven years. There is a material timing difference between the minimum lease payments and expense recognition as calculated under operating lease accounting rules. OPUC issued an order allowing us to align our expense recognition with cash payments for ratemaking purposes. We recorded the difference between the minimum lease payments and the aggregate of the imputed interest on the finance lease obligation and amortization of the right-of-use asset as a regulatory asset on our balance sheet. The balance of the regulatory asset was $9.0 million and $8.0 million as of December 31, 2024 and 2023, respectively.

Finance Leases
NW Natural also leases building storage spaces for use as a gas meter room in order to provide natural gas to multifamily or mixed use developments. These contracts are accounted for as finance leases and typically involve a one-time upfront payment with no remaining liability. The right of use asset for finance leases was $3.0 million and $2.6 million at December 31, 2024 and 2023, respectively.
8. STOCK-BASED COMPENSATION
Stock-based compensation plans are designed to promote stock ownership in NW Holdings by employees and officers of NW Holdings and its affiliates. These compensation plans include a Long Term Incentive Plan (LTIP) and an ESPP.
Long Term Incentive Plan
The LTIP is intended to provide a flexible, competitive compensation program for eligible officers and key employees. Under the LTIP, shares of NW Holdings common stock are authorized for equity incentive grants in the form of stock, restricted stock, restricted stock units, stock options, or performance shares. An aggregate of 1,100,000 shares were authorized for issuance as of December 31, 2024. Shares awarded under the LTIP may be purchased on the open market or issued as original shares.
Of the 1,100,000 shares of common stock authorized for LTIP awards at December 31, 2024, there were 65,153 shares available for issuance under any type of award. This assumes market, performance, and service-based grants currently outstanding are awarded at the target level. There were no outstanding grants of restricted stock or stock options under the LTIP at December 31, 2024 or 2023. The LTIP stock awards are compensatory awards for which compensation expense is based on the fair value of stock awards, with expense being recognized over the performance and vesting period of the outstanding awards. Forfeitures are recognized as they occur.
Performance Shares
LTIP performance shares incorporate a combination of market, performance, and service-based factors. The following table summarizes performance share expense information:
| | | | | | | | | | | | | | | | | | | | |
| Dollars in thousands | | Shares(1) | | Expense During Award Year(2) | | Total Expense for Award |
| Estimated award: | | | | | | |
2022-2024 grant(3) | | 37,059 | | | $ | 1,098 | | | $ | 1,098 | |
| Actual award: | | | | | | |
| 2021-2023 grant | | 40,719 | | | $ | 1,581 | | | $ | 1,581 | |
| 2020-2022 grant | | 29,472 | | | $ | 888 | | | $ | 888 | |
(1) In addition to common stock shares, a participant also receives a dividend equivalent cash payment equal to the number of shares of common stock received on the award payout multiplied by the aggregate cash dividends paid per share during the performance period.
(2) Amount represents the expense recognized in the third year of the vesting period noted above. For the 2020-2022, 2021-2023, and 2022-2024 grants, mutual understanding of the award's key terms was established in the third year of the vesting period, triggering full expense recognition in 2022, 2023, and 2024, respectively.
(3) This represents the estimated number of shares to be awarded as of December 31, 2024 as certain performance share measures have been achieved. Amounts are subject to change with final payout amounts authorized by the Board of Directors in February 2025.
The aggregate number of performance shares granted and outstanding at the target and maximum levels were as follows:
| | | | | | | | | | | | | | | | | | | | | | |
| Dollars in thousands | | Performance Share Awards Outstanding | | 2024 | | |
| Performance Period | | Target | | Maximum | | Expense | | |
| 2022-24 | | 46,156 | | | 92,312 | | | $ | 1,098 | | | |
| 2023-25 | | — | | | — | | | — | | | |
| 2024-26 | | — | | | — | | | — | | | |
| Total | | 46,156 | | | 92,312 | | | $ | 1,098 | | | |
Performance share awards are based on the achievement of a three-year ROIC threshold that must be met and a cumulative EPS factor, which can be modified by a TSR factor relative to a specified peer group (2022-2024, 2023-2025, and 2024-2026 performance share awards) over the three-year performance period. The performance period allows for one of the performance factors to remain variable until the first quarter of the third year of the award period. As the performance factor will not be approved until the first quarter of 2025 and 2026, there is not a mutual understanding of the awards' key terms and conditions between NW Natural and the participants as of December 31, 2024, and therefore, no expense was recognized for the 2023-2025 and 2024-2026 performance period. NW Natural will calculate the grant date fair value and recognize expense once the final performance factor has been approved. If the target is achieved for the 2023-2025 and 2024-2026 awards, NW Holdings would grant for accounting purposes 50,542 and 73,150 shares in the first quarter of 2025 and 2026, respectively.
Compensation expense is recognized in accordance with accounting standards for stock-based compensation and calculated based on performance levels achieved and an estimated fair value using the Monte-Carlo method. Due to there not being a mutual understanding of the 2023-2025 and 2024-2026 awards' key terms and conditions as noted above, the grant date fair value has not yet been determined and no non-vested shares existed at December 31, 2024. The weighted-average grant date fair value of non-vested shares associated with the 2022-2024 awards was $39.70 per share at December 31, 2024. The weighted-average grant date fair value of shares vested during the year was $39.70 per share and there was no unrecognized compensation expense for accounting purposes as of December 31, 2024.
Restricted Stock Units
In 2012, RSUs began being granted under the LTIP instead of stock options under the Restated SOP. Generally, the RSUs awarded are forfeitable and include a performance-based threshold as well as a vesting period of four years from the grant date. The majority of our RSU grants obligate NW Holdings, upon vesting, to issue the RSU holder one share of common stock. The grant may also include a cash payment equal to the total amount of dividends paid per share between the grant date and vesting date of that portion of the RSU depending on the structure of the award agreement. The fair value of an RSU is equal to the closing market price of NW Holdings' common stock on the grant date. During 2024, total RSU expense was $1.9 million compared to $1.9 million in 2023 and $2.1 million in 2022. As of December 31, 2024, there was $3.7 million of unrecognized compensation cost from grants of RSUs, which is expected to be recognized over a period extending through 2028.

Employee Stock Purchase Plan
NW Holdings' ESPP allows employees of NW Holdings, NW Natural and certain designated subsidiaries to purchase common stock at 85% of the closing price on the trading day immediately preceding the initial offering date, which is set annually. For the 2024-2025 ESPP period, each eligible employee may purchase up to $21,226 worth of stock through payroll deductions over a period defined by the Board of Directors, with shares issued at the end of the subscription period.
Stock-Based Compensation Expense
Stock-based compensation expense is recognized as operations and maintenance expense or is capitalized as part of construction overhead at the entity at which the award recipient is employed. The following table summarizes the NW Holdings' financial statement impact, substantially all of which was recorded at NW Natural, of stock-based compensation under the LTIP and ESPP:

9. DEBT
Short-Term Debt
The primary source of short-term liquidity for NW Holdings is cash balances, dividends from its operating subsidiaries, in particular NW Natural, available cash from a multi-year credit facility, and short-term credit facilities it may enter into from time to time.
The primary source of short-term liquidity for NW Natural is from the sale of commercial paper, available cash from a multi-year credit facility, and short-term credit facilities it may enter into from time to time. In addition to issuing commercial paper or entering into bank loans to meet working capital requirements, including seasonal requirements to finance gas purchases and accounts receivable, short-term debt may also be used to temporarily fund capital requirements. For NW Natural, commercial paper and bank loans are periodically refinanced through the sale of long-term debt or equity contributions from NW Holdings. Commercial paper, when outstanding, is sold through two commercial banks under an issuing and paying agency agreement and is supported by one or more unsecured revolving credit facilities. See “Credit Agreements” below.
At December 31, 2024 and 2023, NW Natural's short-term debt consisted of the following:
| | | | | | | | | | | | | | | | | |
| December 31, 2024 | | December 31, 2023 |
| In millions | Balance Outstanding | Weighted Average Interest Rate(1) | | Balance Outstanding | Weighted Average Interest Rate(1) |
| NW Natural: | | | | | |

| Credit agreement | 33.6 | | 5.5 | % | | 73.0 | | 6.4 | % |
| NW Holdings | $ | 170.1 | | | | $ | 89.8 | | |
(1) Weighted average interest rate on outstanding short-term debt
The carrying cost of commercial paper approximates fair value using Level 2 inputs. See Note 2 for a description of the fair value hierarchy. At December 31, 2024, NW Natural's commercial paper had a maximum remaining maturity of 42 days and an average remaining maturity of 22 days.
Credit Agreements
NW Holdings
In November 2021, NW Holdings entered into an amended and restated $200 million credit agreement, with a feature that allows NW Holdings to request increases in the total commitment amount, up to a maximum of $300 million. In December 2024, the maturity date of the agreement was extended to November 2, 2027, with an available extension of commitments for one additional one-year period, subject to lender approval. Interest charges on the NW Holdings credit agreement are indexed the secured overnight financing rate (SOFR) beginning February 2023. The SOFR is subject to a 10 basis point spread adjustment.
The NW Holdings credit agreement permits the issuance of letters of credit in an aggregate amount of up to $40 million. The principal amount of borrowings under the credit agreement is due and payable on the maturity date. The credit agreement requires NW Holdings to maintain a consolidated indebtedness to total capitalization ratio of 70% or less. Failure to comply with this covenant would entitle the lenders to terminate their lending commitments and accelerate the maturity of all amounts outstanding. NW Holdings was in compliance with this covenant at December 31, 2024 and 2023.
The NW Holdings credit agreement also requires NW Holdings to maintain debt ratings (which are defined by a formula using NW Natural's credit ratings in the event NW Holdings does not have a credit rating) with Standard & Poor's (S&P) and Moody's Investors Service, Inc. (Moody’s) and notify the lenders of any change in its senior unsecured debt ratings or senior secured debt ratings, as applicable, by such rating agencies. A change in NW Holdings' debt ratings by S&P or Moody’s is not an event of default, nor is the maintenance of a specific minimum level of debt rating a condition of drawing upon the credit agreement. Rather, interest rates on any loans outstanding under the credit agreements are tied to debt ratings and therefore, a change in the debt rating would increase or decrease the cost of any loans under the credit agreements when ratings are changed. NW Holdings maintains a credit rating with S&P of A- and does not currently maintain ratings with Moody's.
There was $33.6 million and $73.0 million of outstanding balances under the NW Holdings agreement at December 31, 2024 and 2023, respectively. No letters of credit were issued or outstanding under the NW Holdings agreement at December 31, 2024 and 2023.
NW Natural
In November 2021, NW Natural entered into an amended and restated credit agreement for unsecured revolving loans totaling $400 million, with a feature that allows NW Natural to request increases in the total commitment amount, up to a maximum of $600 million. In December 2024, the maturity date of the agreement was extended to November 3, 2027 with an available extension of commitments for one additional one-year period, subject to lender approval. The credit agreement permits the issuance of letters of credit in an aggregate amount of up to $60 million. The principal amount of borrowings under the credit
agreement is due and payable on the maturity date. Interest charges on the NW Natural credit agreement are indexed to the SOFR beginning February 2023. The SOFR is subject to a 10 basis point spread adjustment.
NW Natural's credit agreement requires NW Natural to maintain a consolidated indebtedness to total capitalization ratio of 70% or less. Failure to comply with this covenant would entitle the lenders to terminate their lending commitments and accelerate the maturity of all amounts outstanding. NW Natural was in compliance with this covenant at December 31, 2024 and 2023.
The NW Natural credit agreement also requires NW Natural to maintain credit ratings with S&P and Moody’s and notify the lenders of any change in NW Natural's senior unsecured debt ratings or senior secured debt ratings, as applicable, by such rating agencies. A change in NW Natural's debt ratings by S&P or Moody’s is not an event of default, nor is the maintenance of a specific minimum level of debt rating a condition of drawing upon the credit agreement. Rather, interest rates on any loans outstanding under the credit agreement are tied to debt ratings and therefore, a change in the debt rating would increase or decrease the cost of any loans under the credit agreement when ratings are changed.
There were no letters of credit outstanding at December 31, 2024 under NW Natural's credit agreement and one letter of credit outstanding at December 31, 2023. In December 2023, NW Natural issued a $15 million letter of credit through its existing credit agreement, which expired January 5, 2024.
Letters of Credit Facility
In January 2024, NW Natural entered into an Uncommitted Letter of Credit and Reimbursement Agreement (LC Reimbursement Agreement), pursuant to which NW Natural agreed to reimburse each Lender acting as an issuing bank (Issuing Bank) thereunder for disbursements in respect of letters of credit (Letters of Credit) issued pursuant to the LC Reimbursement Agreement from time to time. The Company expects to use Letters of Credit issued under the facility created by the LC Reimbursement Agreement (LC Facility) primarily to support its participation in Washington Climate Commitment Act cap-and-invest program auctions.
Although there is no expressly stated maximum amount of Letters of Credit that can be issued or outstanding under the LC Facility, under current regulatory authority from the OPUC, the aggregate sum of Letters of Credit outstanding and available to be drawn under the LC Reimbursement Agreement may not exceed $100 million at any one time. The Issuing Banks have no commitment to issue Letters of Credit under the LC Facility and will have the discretion to limit and condition the terms for the issuance of Letters of Credit (including maximum face amounts) in their sole discretion.
The LC Reimbursement Agreement requires NW Natural to maintain certain ratings with S&P and Moody’s. NW Natural must also notify the Administrative Agent and Lenders of any change in the S&P or Moody’s Ratings, although any such change is not an event of default.
The LC Reimbursement Agreement prohibits NW Natural from permitting Consolidated Indebtedness to be greater than 70% of Total Capitalization, each as defined therein and calculated as of the end of each fiscal quarter of NW Natural. Failure to comply with this financial covenant would constitute an Event of Default under the LC Reimbursement Agreement. The occurrence of this or any other Event of Default would entitle the Administrative Agent to require cash collateral for the LC Exposure, as defined in the LC Reimbursement Agreement, and to exercise all other rights and remedies available to it and the Lenders under the Credit Documents, as defined in the LC Reimbursement Agreement, and under applicable law.
There were no letters of credit issued or outstanding under the LC Reimbursement Agreement at December 31, 2024.

NW Natural Long-Term Debt
NW Natural's issuance of First Mortgage Bonds (FMBs), which includes NW Natural's medium-term notes, under the Mortgage and Deed of Trust (Mortgage) is limited by eligible property, adjusted net earnings, and other provisions of the Mortgage. The Mortgage constitutes a first mortgage lien on certain gas properties owned from time to time by NW Natural, including substantially all of NW Natural's NGD property.

In December 2023, NW Holdings entered into a Note Purchase Agreement between NW Holdings and the institutional investors named as purchasers therein. The Note Purchase Agreement provides for the issuance of (i) $100.0 million aggregate principal amount of NW Holdings’ 5.78% Senior Notes, Series A, due March 7, 2028 (5.78% Notes) and (ii) $50.0 million aggregate principal amount of NW Holdings’ 5.84% Senior Notes, Series B, due March 7, 2029 (5.84% Notes) in reliance on an exemption from registration under Section 4(a)(2) of the Securities Act of 1933, as amended. The 5.78% Notes and the 5.84% Notes were issued in March 2024, pursuant to the Note Purchase Agreement. The proceeds from the Note Purchase Agreement were used to settle an existing term loan at NW Holdings for $100.0 million and make an equity contribution to NWN Water, which was used to settle an existing term loan for $50.0 million.
In December 2024, NW Holdings issued and sold (i) $90.0 million in aggregate principal amount of its 5.52% Senior Notes, Series C, due December 19, 2029 (the 5.52% Notes), and (ii)$45.0 million in aggregate principal amount of its 5.86% Senior Notes, Series D, due December 19, 2034 (the 5.86% Notes, together with the 5.52% Notes, the Notes), to certain institutional investors pursuant to a Note Purchase Agreement dated December 19, 2024 (the Note Purchase Agreement), in reliance on an exemption from registration under Section 4(a)(2) of the Securities Act of 1933, as amended.
The 5.52% Notes and the 5.86% Notes bear interest at the rate of 5.52% and 5.86%, respectively, per annum, payable semi-annually on June 19 and December 19 of each year, commencing June 19, 2025, and will mature on December 19, 2029, and December 19, 2034, respectively. The 5.52% Notes and the 5.86% Notes will be subject to prepayment at the option of NW Holdings, in whole or in part, (i) at any time at a price equal to 100% of the principal amount thereof, plus the applicable “make-whole” premium and accrued and unpaid interest thereon to the date of prepayment, and (ii) at any time on or after November 19, 2029 and September 19, 2034, respectively, at 100% of the principal amount thereof, plus accrued and unpaid interest thereon to the date of prepayment, but without the payment of a “make-whole” premium, in each case, so long as there is no Default or Event of Default under the Note Purchase Agreement.
Interest Rate Swap Agreement
In January 2023, NWN Water entered into an interest rate swap agreement with a major financial institution for $55.0 million that effectively converted variable-rate debt to a fixed rate of 3.80%. Interest payments made between the effective date and expiration date are hedged by the swap agreement. The interest rate swap agreement expires in June 2026, along with the variable-rate debt.

Fair Value of Long-Term Debt
NW Holdings' and NW Natural's outstanding debt does not trade in active markets. The fair value of debt is estimated using the value of outstanding debt at natural gas distribution companies with similar credit ratings, terms, and remaining maturities to NW Holdings' and NW Natural's debt that actively trade in public markets. Substantially all outstanding debt at NW Holdings is comprised of NW Natural debt. These valuations are based on Level 2 inputs as defined in the fair value hierarchy. See Note 2.
The following table provides an estimate of the fair value of long-term debt, including current maturities of long-term debt, using market prices in effect on the valuation date:

10. PENSION AND OTHER POSTRETIREMENT BENEFIT COSTS
NW Natural maintains a qualified non-contributory defined benefit pension plan (Pension Plan) for all eligible employees, non-qualified supplemental pension plans for eligible executive officers and other key employees, and other postretirement employee benefit plans. NW Natural also has a qualified defined contribution plan (Retirement K Savings Plan) for all eligible employees. The Pension Plan and Retirement K Savings Plan have plan assets, which are held in qualified trusts to fund retirement benefits.
Effective January 1, 2007 and 2010, the Pension Plan and postretirement benefits for non-union employees and union employees, respectively, were closed to new participants. Non-union and union employees hired or re-hired after December 31, 2006 and 2009, respectively, and employees of NW Natural subsidiaries are provided an enhanced Retirement K Savings Plan benefit.
The following table provides a reconciliation of the changes in NW Natural's benefit obligations and fair value of plan assets, as applicable, for NW Natural's pension and other postretirement benefit plans, excluding the Retirement K Savings Plan, and a summary of the funded status and amounts recognized in NW Holdings' and NW Natural's consolidated balance sheets as of December 31:

At December 31, 2024, the net liability (benefit obligations less market value of plan assets) for the Pension Plan decreased $20.5 million compared to 2023. The decrease in the net pension liability is primarily due to the $19.8 million decrease to the pension benefit obligation and the $0.7 million increase in plan assets. The liability for non-qualified plans decreased $0.1 million, and the liability for other postretirement benefits increased $0.6 million in 2024.
NW Natural's Pension Plan had a projected benefit obligation of $372.8 million and $392.6 million at December 31, 2024 and 2023, respectively, and fair values of plan assets of $284.1 million and $283.4 million, respectively. The plan had an accumulated benefit obligation of $343.7 million and $363.5 million at December 31, 2024 and 2023, respectively.

In 2025, NW Natural will amortize $9.1 million in estimated costs from regulatory assets to net periodic benefit costs.
The assumed discount rates for NW Natural's Pension Plan and other postretirement benefit plans were determined independently based on the FTSE Above Median Curve (discount rate curve), which uses high quality corporate bonds rated AA- or higher by S&P or Aa3 or higher by Moody’s. The discount rate curve was applied to match the estimated cash flows in each of the plans to reflect the timing and amount of expected future benefit payments for these plans.
The assumed expected long-term rate of return on plan assets for the Pension Plan was developed using a weighted-average of the expected returns for the target asset portfolio. In developing the expected long-term rate of return assumption, consideration was given to the historical performance of each asset class in which the plan’s assets are invested and the target asset allocation for plan assets.
The investment strategy and policies for Pension Plan assets held in the retirement trust fund were approved by the NW Natural Retirement Committee, which is composed of senior management with the assistance of an outside investment consultant. The policies set forth the guidelines and objectives governing the investment of plan assets. Plan assets are invested for total return with appropriate consideration for liquidity, portfolio risk, and return expectations. All investments are expected to satisfy the prudent investments rule under the Employee Retirement Income Security Act of 1974. The approved asset classes may include cash and short-term investments, fixed income, common stock and convertible securities, absolute and real return strategies, and real estate. Plan assets may be invested in separately managed accounts or in commingled or mutual funds. Investment re-balancing takes place periodically as needed, or when significant cash flows occur, in order to maintain the allocation of assets within the stated target ranges. The retirement trust fund for the Pension Plan is not currently invested in NW Holdings or NW Natural securities.
The following table presents the Pension Plan asset target allocation at December 31, 2024:
| | | | | |
| Asset Category | Target Allocation |
| Long government/credit | 40 | % |
| U.S. large cap equity | 21 | |
| Global equity | 15 | |
| Developed non-U.S. equity | 11 | |
| Emerging market equity | 5 | |
| High yield bonds | 4 | |
| Real estate investment trusts | 2 | |
| Emerging market debt | 2 | |
Non-qualified supplemental defined benefit plan obligations were $32.7 million and $32.8 million at December 31, 2024 and 2023, respectively. These plans are not subject to regulatory deferral, and the changes in actuarial gains and losses, prior
service costs, and transition assets or obligations are recognized in AOCL, net of tax until they are amortized as a component of net periodic benefit cost. These are unfunded, non-qualified plans with no plan assets; however, a significant portion of the obligations is indirectly funded with company and trust-owned life insurance and other assets.
Other postretirement benefit plans are unfunded plans but are subject to regulatory deferral. The actuarial gains and losses, prior service costs, and transition assets or obligations for these plans are recognized as a regulatory asset.
Net periodic benefit costs consist of service costs, interest costs, the expected returns on plan assets, and the amortization of gains and losses and prior service costs. The gains and losses are the sum of the actuarial and asset gains and losses throughout the year and are amortized over the average remaining service period of active participants. The asset gains and losses are based in part on a market-related valuation of assets. The market-related valuation reflects differences between expected returns and actual investment returns with the differences recognized over a two-year period from the year in which they occur, thereby reducing year-to-year net periodic benefit cost volatility.
The service cost component of net periodic benefit cost for NW Natural pension and other postretirement benefit plans is recognized in operations and maintenance expense in the consolidated statements of comprehensive income. The other non-service cost components are recognized in other income (expense), net in the consolidated statements of comprehensive income. The following table provides the components of net periodic benefit cost for NW Natural's pension and other postretirement benefit plans for the years ended December 31:

Net periodic benefit costs are reduced by amounts capitalized to NGD plant. In addition, a certain amount of net periodic benefit costs were recorded to the regulatory balancing account, representing net periodic pension expense for the Pension Plan above the amount set in rates, as approved by the OPUC, from 2011 through October 31, 2018. Total amortization of the regulatory balancing account of $7.1 million was recognized in each of the years ended December 31, 2024 and 2023, of which $2.6 million was charged to operations and maintenance expense and $4.5 million was charged to other income (expense).
The following table provides the assumptions used in measuring periodic benefit costs and benefit obligations for the years ended December 31:

| Expected long-term rate of return | | 7.50 | % | | 7.50 | % | | 7.50 | % | | n/a | | n/a | | n/a |
(1) Rate assumption ranges from 4.8% to 5.1% in 2025 and thereafter.
The assumed annual increase in health care cost trend rates used in measuring other postretirement benefits as of December 31, 2024 was 6.00%. These trend rates apply to both medical and prescription drugs. Medical costs and prescription drugs are assumed to decrease gradually each year to a rate of 4.00% by 2029.
Assumed health care cost trend rates can have a significant effect on the amounts reported for the health care plans; however, other postretirement benefit plans have a cap on the amount of costs reimbursable by NW Natural.
Mortality assumptions are reviewed annually and are updated for material changes as necessary. In 2024, mortality rate assumptions remained consistent with 2023, using Pri-2012 mortality tables using scale MP-2021.

Employer Contributions to Company-Sponsored Defined Benefit Pension Plan
NW Natural makes contributions to its Pension Plan based on actuarial assumptions and estimates, tax regulations, and funding requirements under federal law. The American Rescue Plan, which was signed into law on March 11, 2021, includes a provision for pension relief that extends the amortization period for required contributions from 7 to 15 years and provides for the stabilization of interest rates used to calculate future required contributions. NW Natural made $20.5 million of cash contributions to its Pension Plan for 2024.
The Pension Plan was underfunded by $88.7 million at December 31, 2024. During 2025, NW Natural expects to make cash contributions of approximately $11.3 million to the Pension Plan.
Multiemployer Pension Plan
In addition to the NW Natural-sponsored Pension Plan presented above, prior to 2014 NW Natural contributed to a multiemployer pension plan for its NGD union employees known as the Western States Office and Professional Employees International Union Pension Fund (Western States Plan). That plan's employer identification number is 94-6076144. Effective December 22, 2013, NW Natural withdrew from the plan, which was a noncash transaction. Vested participants will receive all benefits accrued through the date of withdrawal. As the plan was underfunded at the time of withdrawal, NW Natural was assessed a withdrawal liability of $8.3 million, plus interest, which requires NW Natural to pay $0.6 million each year to the plan for 20 years beginning in July 2014. The cost of the withdrawal liability was deferred to a regulatory account on the balance sheet.
Payments were $0.6 million for 2024, and as of December 31, 2024, the liability balance was $4.7 million. For 2023 and 2022, contributions to the plan were $0.6 million each year, which was approximately 17% to 1% of the total contributions to the plan by all employer participants in those years.
Defined Contribution Plan
NW Natural's Retirement K Savings Plan is a qualified defined contribution plan under Internal Revenue Code Sections 401(a) and 401(k). NW Natural contributions totaled $11.1 million, $10.4 million, and $9.6 million for 2024, 2023, and 2022, respectively.
Deferred Compensation Plans
NW Natural's supplemental deferred compensation plans for eligible officers and senior managers are non-qualified plans. These plans are designed to enhance the retirement savings of employees and to assist them in strengthening their financial security by providing an incentive to save and invest regularly.
Fair Value
Below is a description of the valuation methodologies used for assets measured at fair value. In cases where NW Natural's Pension Plan is invested through a collective trust fund or mutual fund, the fund's market value is utilized. Market values for investments directly owned are also utilized.
U.S. EQUITY. These are non-published net asset value (NAV) assets. The non-published NAV assets consist of commingled trusts where NAV is not published but the investment can be readily disposed of at NAV or market value. The underlying investments in this asset class includes investments primarily in U.S. common stocks.
INTERNATIONAL/GLOBAL EQUITY. These are Level 1 and non-published NAV assets. The Level 1 asset is a mutual fund, and the non-published NAV assets consist of commingled trusts where the NAV/unit price is not published, but the investment can be readily disposed of at the NAV/unit price. The mutual fund has a readily determinable fair value, including a published NAV, and the commingled trusts are valued at unit price. This asset class includes investments primarily in foreign equity common stocks.
LIABILITY HEDGING. These are non-published NAV assets. The non-published NAV assets consist of commingled trusts where NAV is not published but the investment can be readily disposed of at NAV or market value. The underlying investments in this asset class include long duration fixed income investments primarily in U.S. treasuries, U.S. government agencies, municipal securities, mortgage-backed securities, asset-backed securities, as well as U.S. and international investment-grade corporate bonds.
OPPORTUNISTIC. These are non-published NAV assets. The non-published NAV assets consist of commingled trusts where NAV is not published but the investment can be readily disposed of at NAV or market value. The underlying investments in this asset class include real estate investment trust equities, high yield bonds, floating rate debt, emerging market debt and a commodity index pool.
CASH AND CASH EQUIVALENTS. These are non-published NAV assets. The non-published NAV assets represent mutual funds without published NAV's but the investment can be readily disposed of at the NAV. The mutual funds are valued at the NAV of the shares held by the plan at the valuation date.
The preceding valuation methods may produce a fair value calculation that is not indicative of net realizable value or reflective of future fair values. Although we believe these valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain investments could result in a different fair value measurement at the reporting date.
Commingled trust investments are subject to a redemption notice period of five business days. There were no unfunded commitments for Plan investments as of December 31, 2024 and 2023.
Investment securities are exposed to various financial risks including interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of NW Natural's investment securities will occur in the near term and such changes could materially affect NW Natural's investment account balances and the amounts reported as plan assets available for benefit payments.
The following tables present the fair value of NW Natural's Pension Plan assets, including outstanding receivables and liabilities, of NW Natural's retirement trust fund:

(1) The fair value for these investments is determined using Net Asset Value per share (NAV) as of December 31, as a practical expedient, and therefore they are not classified within the fair value hierarchy. These investments primarily consist of institutional investment products, for which the NAV is generally not publicly available.
11. INCOME TAX
The following table provides a reconciliation between income taxes calculated at the statutory federal tax rate and the provision for income taxes reflected in the NW Holdings and NW Natural statements of comprehensive income or loss for December 31:

| Effective tax rate | | 28.3% | | 25.6% | | 25.2% | | 28.0% | | 25.4% | | 25.3% |
The NW Holdings and NW Natural effective income tax rates for 2024 compared to 2023 changed primarily as a result of pre-tax income and a regulatory tax benefit that was fully amortized in customer rates in 2023.
The NW Holdings and NW Natural effective income tax rates for 2023 compared to 2022 changed primarily as a result of pre-tax income.
The provision for current and deferred income taxes consists of the following at December 31:

At December 31, 2024 and 2023, regulatory income tax assets of $5.8 million and $8.0 million, respectively, were recorded by NW Natural, a portion of which is recorded in current assets. These regulatory income tax assets primarily represent future rate recovery of deferred tax liabilities, resulting from differences in NGD plant financial statement and tax bases and NGD plant removal costs, which were previously flowed through for rate making purposes and to take into account the additional future taxes, which will be generated by that recovery. These deferred tax liabilities, and the associated regulatory income tax assets, are currently being recovered through customer rates. At December 31, 2024 and 2023, regulatory income tax assets of $6.0 million and $4.9 million, respectively, were recorded by NW Natural, representing future recovery of deferred tax liabilities resulting from the equity portion of AFUDC.
At December 31, 2024 and 2023, deferred tax assets of $44.9 million and $46.1 million, respectively, were recorded by NW Natural representing the future income tax benefit associated with the excess deferred income tax regulatory liability recorded as a result of the lower federal corporate income tax rate provided for by the TCJA. At December 31, 2024 and 2023, regulatory liability balances representing the benefit of the change in deferred taxes as a result of the TCJA of $169.5 million and $174.2 million, respectively, were recorded by NW Natural.
NW Holdings and NW Natural assess the available positive and negative evidence to estimate if sufficient taxable income will be generated to utilize their respective existing deferred tax assets. Based upon this assessment, NW Holdings and NW Natural determined that it is more likely than not that all of their respective deferred tax assets recorded as of December 31, 2024 will be realized.
The Company estimates it has net operating loss (NOL) carryforwards of $138 thousand for federal taxes and $147 thousand for state taxes at December 31, 2024. The federal NOLs do not expire and we anticipate fully utilizing the state NOL carryforward
balances before they begin to expire in 2036. California alternative minimum tax (AMT) credits of $56 thousand are also available. The AMT credits do not expire.
Uncertain tax positions are accounted for in accordance with accounting standards that require an assessment of the anticipated settlement outcome of material uncertain tax positions taken in a prior year, or planned to be taken in the current year. Until such positions are sustained, the uncertain tax benefits resulting from such positions would not be recognized. No reserves for uncertain tax positions were recorded as of December 31, 2024, 2023, or 2022.
The federal income tax returns for tax years 2020 and earlier are closed by statute. The IRS Compliance Assurance Process (CAP) examination of the 2021 and 2022 tax years have been completed. There were no material changes to these returns as filed. The 2023 and 2024 tax years are currently under IRS CAP examination. The 2025 CAP application has been filed. Under the CAP program, NW Holdings and NW Natural work with the IRS to identify and resolve material tax matters before the tax return is filed each year.
As of December 31, 2024, income tax years 2020 through 2023 remain open for examination by the states of California and Texas. Income tax years 2021 through 2023 are open for examination by the states of Idaho, Nebraska, and Oregon. Income tax years 2022 through 2023 are open for examination by the state of Arizona.

NW Natural
NGD balances primarily consist of transmission and distribution plant, gas storage facilities, general plant and other fixed assets. In October 2024, the OPUC issued an order concluding the NW Natural 2024 Oregon rate case. The OPUC ordered a regulatory disallowance related to $13.7 million of undepreciated line extension costs, which resulted in a reduction of NGD plant in service and a non-cash, pre-tax charge that was recorded as operations and maintenance expense in the consolidated statements of comprehensive income in the fourth quarter of 2024.
Other plant balances include non-utility gas storage assets at the Mist facility and other long-lived assets not related to NGD.
The weighted average depreciation rate for NGD assets was 2.9% in 2024, 3.0% in 2023, and 3.0% 2022. The weighted average depreciation rate for assets not related to NGD was 1.7% in 2024, 1.7% in 2023 and 1.8% in 2022.
Accumulated depreciation does not include the accumulated provision for asset removal costs of $526.5 million and $496.2 million at December 31, 2024 and 2023, respectively. These accrued asset removal costs are reflected on the balance sheet as regulatory liabilities. See Note 2.
NW Holdings
Other plant balances include long-lived assets associated with water and wastewater operations and non-regulated activities not held by NW Natural or its subsidiaries.
13. INVESTMENTS
Investments include gas reserves, financial investments in life insurance policies, and equity method investments. The following table summarizes other investments at December 31:

Investment in Life Insurance Policies
NW Natural has invested in key person life insurance contracts to provide an indirect funding vehicle for certain long-term employee and director benefit plan liabilities. The amount in the above table is reported at cash surrender value, net of policy loans.
NW Natural Gas Reserves
NW Natural has invested $188 million through the gas reserves program in the Jonah Field located in Wyoming as of December 31, 2024. Gas reserves are stated at cost, net of regulatory amortization, with the associated deferred tax benefits of $2.6 million and $4.0 million, which are recorded as liabilities in the December 31, 2024 and 2023 consolidated balance sheets, respectively. NW Natural's investment is included in NW Holdings' and NW Natural's consolidated balance sheets under other current assets and other investments (non-current portion) with the maximum loss exposure limited to the investment balance. The amount of gas reserves included in other current assets was $2.7 million and $2.3 million as of December 31, 2024 and 2023, respectively. The investment in gas reserves provides long-term price protection and acted to hedge the cost of gas for approximately 3% and 3% of NGD gas supplies for the years ended December 31, 2024 and 2023, respectively.
Investments in Unconsolidated Affiliates
In December 2021, NWN Water purchased a 37.3% ownership stake in Avion Water Company, Inc. (Avion Water), an investor-owned water utility for $14.5 million. NWN Water subsequently increased its ownership stake in Avion Water as follows:
| | | | | | | | | | | | | | |
| In millions | | Amount | | Ownership % |
| July 2022 | | $ | 1.0 | | | 40.3 | % |
| June 2023 | | $ | 1.0 | | | 43.1 | % |
| January 2024 | | $ | 1.0 | | | 45.6 | % |
| February 2025 | | $ | 1.0 | | | 47.9 | % |
Avion Water operates in Bend, Oregon and the surrounding communities, serving approximately 16,000 customer connections and employing 38 people. The carrying value of the equity method investment is $9.8 million higher than the underlying equity in the net assets of the investee at December 31, 2024 due to equity method goodwill. NWN Water's share in the earnings (loss) of Avion Water is included in other income (expense), net.
In 2020, NW Natural began a partnership with BioCarbN to invest in renewable natural gas (RNG) development facilities that are designed to access biogas derived from water treatment at Tyson Foods’ processing plants, subject to approval by all parties. In January 2022, commissioning of the first facility, Lexington Renewable Energy LLC (Lexington), was completed. In April 2023, commissioning of the second facility, Dakota City Renewable Energy LLC (Dakota City), was completed. NW Natural recorded the investment as an equity method investment. As of December 31, 2023, NW Natural had an investment balance in Lexington and Dakota City of $19.5 million.
In January 2024, NW Natural replaced BioCarbN as manager of the Lexington and Dakota City companies. As a result, NW Natural determined that these investments no longer qualified as an equity method investment and were fully consolidated for the year ended December 31, 2024.
14. BUSINESS COMBINATIONS

The acquisition added wastewater and recycled water customers across Oregon, Idaho and California. The acquisition-date fair value of the total consideration transferred was approximately $29.9 million.
The ICH acquisition met the criteria of a business combination, and as such a preliminary allocation of the consideration to the acquired net assets based on their estimated fair value as of the acquisition date was performed. In accordance with U.S. GAAP, the fair value determination involves management judgment in determining the significant estimates and assumptions used for net assets associated with ICH. This allocation is considered preliminary as of December 31, 2024, as facts and circumstances that existed as of the acquisition date may be discovered as we continue to integrate ICH. As a result, subsequent adjustments to the preliminary valuation of tangible assets, contract assets and liabilities, tax positions, and goodwill may be required. Subsequent adjustments are not expected to be significant, and any such adjustments are expected to be completed within the one-year measurement period. The acquisition costs were not material and expensed as incurred.
Preliminary goodwill of $18.4 million was recognized from this acquisition. The goodwill recognized is attributable to ICH's water utility service territory, experienced workforce, and the strategic benefits for both the water utility and wastewater services expected from growth in its service territory. No intangible assets aside from goodwill were recognized. The amount of goodwill that is expected to be deductible for income tax purposes is approximately $18.4 million.
The preliminary purchase price for the acquisition has been allocated to the net assets acquired as of the acquisition date and is as follows:

| Total net assets acquired | $ | 29,902 | |
The amount of ICH revenues included in NW Holdings' consolidated statements of comprehensive income is $1.9 million for the year ended December 31, 2024. Earnings from ICH activities for the year ended December 31, 2024 were not material to the results of NW Holdings.
2023 Business Combinations
During the year ended December 31, 2023, NWN Water and its subsidiaries acquired the assets of five businesses qualifying as business combinations. The aggregate fair value of the total consideration transferred for these acquisitions was $22.8 million, most of which was preliminarily allocated to property, plant, and equipment, and goodwill. These transactions align with NW Holdings' water and wastewater sector strategy as it continues to expand its water and wastewater service territories and included:
•Pedersen Family, LLC in Washington
•King Water Corporation in Washington
•Rose Valley Water Company in Arizona
•Hiland Water in Oregon
•Truxton and Cerbat in Arizona
Intangible Assets
In connection with the acquisition of King Water Corporation, NWN Water recorded long-term customer relationship intangible assets totaling $2.6 million, which will be amortized over 24 years. There was $0.2 million of amortization expense recognized in 2024 and no amortization expense recognized in 2023. Projected amortization expense at NW Holdings for customer relationship intangible assets for each of the next five years is $0.1 million in each period. The amortization will change in future periods if other intangible assets are acquired, impairments are recognized or the preliminary valuations as part of our purchase price allocation is refined.
2022 Business Combinations
Far West Water & Sewer, Inc.
On October 5, 2022, NWN Water completed the acquisition of the water and wastewater utilities of Far West Water & Sewer, Inc. (Far West), which has a combined approximately 25,000 connections in Yuma, Arizona. The acquisition-date fair value of the total consideration transferred, after closing adjustments, was approximately $97.0 million, of which $88.4 million was cash consideration transferred at closing, $8.1 million was contingent consideration, and $0.5 million was deferred consideration.
The contingent consideration is an earnout payment in an amount equal to the product of (i) the amount, if any, by which the average annual System Operating Revenue for the 2026, 2027, and 2028 years exceeds $13.0 million (ii) multiplied by 4 but shall not exceed $12.0 million. As of the acquisition date, the contingent consideration had a fair value of $8.1 million and was included in other non-current liabilities. The fair value as of the acquisition date was determined using a scenario-based technique using management's best estimate of forecast revenue for the years 2026, 2027, and 2028 discounted to present value. The inputs to determine the fair value of the contingent consideration include estimated future revenue and a risk-adjusted discount rate. The fair value measurement is based on significant inputs that are not observable in the market and thus represents a fair value measurement categorized within Level 3 of the fair value hierarchy per ASC Topic 820.
The Far West acquisition met the criteria of a business combination, and as such an allocation of the consideration to the acquired net assets based on their estimated fair value as of the acquisition date was performed. In accordance with U.S. GAAP, the fair value determination involves management judgment in determining the significant estimates and assumptions used and was made using existing regulatory conditions for net assets associated with Far West. The acquisition costs were expensed as incurred.
Goodwill of $69.9 million was recognized from this acquisition. The goodwill recognized is attributable to Far West's regulated water utility service territory, experienced workforce, and the strategic benefits for both the water utility and wastewater services expected from growth in its service territory. No intangible assets aside from goodwill were recognized. The amount of goodwill that is expected to be deductible for income tax purposes is approximately $63.3 million.
The purchase price for the acquisition has been allocated to the net assets acquired as of the acquisition date and is as follows:
| | | | | |
| In thousands | |
| Current assets | $ | 1,569 | |
| Property, plant and equipment | 25,974 | |
| Goodwill | 69,890 | |

| |
| Current liabilities | (991) | |
| Non-current liabilities | (9,115) | |
| Total net assets acquired | $ | 88,404 | |
The amount of Far West revenues included in NW Holdings' consolidated statements of comprehensive income is $2.9 million for the year ended December 31, 2022. Earnings from Far West activities for the year ended December 31, 2022 were not material to the results of NW Holdings. Far West is referred to as Foothills Utilities following the closure of the acquisition.
Other 2022 Business Combinations
During the year ended December 31, 2022, NWN Water and its subsidiaries acquired the assets of six additional businesses qualifying as business combinations. The aggregate fair value of the consideration transferred for these acquisitions was $8.7 million, most of which was allocated to property, plant and equipment and goodwill. These transactions align with NW Holdings' water and wastewater sector strategy as it continues to expand its water and wastewater service territories and included:
•Belle Oaks Water and Sewer Co., Inc in Texas
•Northwest Water Services, LLC in Washington
•Aquarius Utilities, LLC in Washington
•Valiant Idaho, LLC (The Idaho Club - Sewer) in Idaho
•Caney Creek in Texas
•Water Necessities, Inc. and Rural Water Co. in Texas
Goodwill
NW Holdings allocates goodwill to reporting units based on the expected benefit from the business combination. We perform an annual impairment assessment of goodwill at the reporting unit level, or more frequently if events and circumstances indicate that goodwill might be impaired. An impairment loss is recognized if the carrying value of a reporting unit’s goodwill exceeds its fair value.
As a result of all acquisitions completed, total goodwill was $183.8 million as of December 31, 2024 and $163.3 million as of December 31, 2023. The increase in the goodwill balance was primarily due to additions associated with our acquisitions in the water and wastewater sector. All of our goodwill is related to water and wastewater acquisitions and is included in the other category for segment reporting purposes. The annual impairment assessment of goodwill occurs in the fourth quarter of each year. There have been no impairments recognized to date.
15. DERIVATIVE INSTRUMENTS
NW Natural
NW Natural enters into financial derivative contracts primarily to hedge a portion of the NGD segment’s natural gas sales requirements. These contracts include swaps, options, and option combinations. These derivative financial instruments are primarily used to manage commodity price variability. A small portion of NW Natural's derivative hedging strategy involves hedging interest rates and foreign currency forward contracts.
NW Natural enters into these financial derivatives, up to prescribed limits, primarily to hedge price variability related to term physical gas supply contracts. The foreign currency forward contracts are used to hedge the fluctuation in foreign currency exchange rates for pipeline demand charges paid in Canadian dollars.
In the normal course of business, NW Natural also enters into indexed-price physical forward natural gas commodity purchase contracts and options to meet the requirements of NGD customers. These contracts qualify for regulatory deferral accounting treatment.
Notional Amounts
The following table presents the absolute notional amounts related to open positions on NW Natural derivative instruments:
| | | | | | | | | | | | | | |
| | At December 31, |
| In thousands | | 2024 | | 2023 |
| Natural gas (in therms): | | | | |

| Physical | | 560,900 | | | 571,610 | |
| Foreign exchange | | $ | 10,332 | | | $ | 11,926 | |
Purchased Gas Adjustment (PGA)
Rates and hedging approaches may vary between states due to different rate structures and mechanisms. Under the PGA mechanism in Oregon, derivatives entered into by NW Natural for the procurement or hedging of natural gas for future gas years generally receive regulatory deferral accounting treatment. In general, commodity hedging for the current gas year is completed prior to the start of the gas year, and hedge prices are fully recovered and reflected in the weighted-average cost of gas in the PGA filing. Hedge contracts entered into after the start of the PGA period for the current PGA year are subject to the PGA incentive sharing mechanism in Oregon. Under the PGA mechanism in Washington, NW Natural incorporates a risk-responsive hedging strategy, and receives regulatory deferral accounting treatment for its Washington gas supplies.
NW Natural entered the 2023-24 gas year with total forecasted sales volumes hedged at approximately 82%, including 66% in financial hedges and 16% in physical gas supplies. The total hedged was approximately 85% in Oregon and 55% in Washington. NW Natural entered the 2024-25 gas year with total forecasted sales volume hedged at approximately 80%, including 64% in financial hedges and 16% in physical gas supplies. The total hedged was approximately 86% in Oregon and 32% in Washington.
Unrealized and Realized Gain/Loss
The following table reflects the income statement presentation for the unrealized gains and losses from NW Natural's derivative instruments:
| | | | | | | | | | | | | | | | | | | | | | | | | | |
| | December 31, 2024 | | December 31, 2023 |
| In thousands | | Natural gas commodity | | Foreign exchange | | Natural gas commodity | | Foreign exchange |
| Benefit (expense) to cost of gas | | $ | 4,431 | | | $ | (524) | | | $ | (131,833) | | | $ | 168 | |
| | | | | | | | |
| Amounts deferred to regulatory accounts on balance sheet | | (4,431) | | | 524 | | | 131,833 | | | (168) | |
| Total gain (loss) in pre-tax earnings | | $ | — | | | $ | — | | | $ | — | | | $ | — | |
Unrealized Gain/Loss
Outstanding derivative instruments related to regulated NGD operations are deferred in accordance with regulatory accounting standards. The cost of foreign currency forward and natural gas derivative contracts are recognized immediately in the cost of gas; however, costs above or below the amount embedded in the current year PGA are subject to a regulatory deferral tariff and therefore, are recorded as a regulatory asset or liability.
Realized Gain/Loss
NW Natural realized a net loss of $119.2 million and a net gain of $125.5 million for the years ended December 31, 2024 and 2023, respectively, from the settlement of natural gas financial derivative contracts. Realized gains and losses offset the higher or lower cost of gas purchased, resulting in no incremental amounts to collect or refund to customers.
Credit Risk Management of Financial Derivatives Instruments
No collateral was posted with or by NW Natural counterparties as of December 31, 2024 or 2023. NW Natural attempts to minimize the potential exposure to collateral calls by diversifying counterparties and using credit limits to manage liquidity risk. Counterparties generally allow a certain credit limit threshold based on our credit rating before requiring NW Natural to post collateral against unrealized loss positions. Given NW Natural's credit ratings, counterparty credit limits and portfolio diversification, it was not subject to collateral calls in 2024 or 2023. The collateral call exposure is set forth under credit support agreements, which generally contain credit limits. NW Natural could also be subject to collateral call exposure where it has agreed to provide adequate assurance, which is not specific as to the amount of credit limit allowed, but could potentially require additional collateral posting by NW Natural in the event of a material adverse change in NW Natural's ability to perform.
NW Natural's financial derivative instruments are subject to master netting arrangements; however, they are presented on a gross basis in the consolidated balance sheets. NW Natural and its counterparties have the ability to set-off obligations to each other under specified circumstances. Such circumstances may include a defaulting party, a credit change due to a merger affecting either party, or any other termination event.
If netted by its counterparties, NW Natural's physical and financial derivative position would result in an asset of $4.4 million and a liability of $86.0 million as of December 31, 2024, and an asset of $9.0 million and a liability of $124.2 million as of December 31, 2023.
NW Natural is exposed to derivative credit and liquidity risk primarily through securing fixed-price natural gas commodity swaps and interest rate swaps with financial counterparties. NW Natural utilizes master netting arrangements with International Swaps and Derivatives Association (ISDA) contracts to minimize these risks including ISDA Credit Support Agreements with counterparties based on their credit ratings. Additionally, NW Natural uses counterparty, industry, sector and country diversification to minimize credit risk. In certain cases, NW Natural may require counterparties to post collateral, guarantees, or letters of credit to maintain its minimum credit requirement standards or for liquidity management purposes.
NW Natural's financial derivatives policy requires counterparties to have an investment-grade credit rating at the time the derivative instrument is entered into, and specifies limits on the contract amount and duration based on each counterparty’s credit rating. NW Natural does not speculate in derivatives. Derivatives are used to manage NW Natural's market risk and we hedge exposure above risk tolerance limits. It is required that increases in market risk created by the use of derivatives is offset by the exposures they modify.
We actively monitor NW Natural's derivative credit exposure and place counterparties on hold for trading purposes or require other forms of credit assurance, such as letters of credit, cash collateral, or guarantees as circumstances warrant. The ongoing assessment of counterparty credit risk includes consideration of credit ratings, credit default swap spreads, bond market credit spreads, financial conditions, government actions, and market news. A Monte Carlo simulation model is used to estimate the change in credit and liquidity risk from the volatility of natural gas prices. The results of the model are used to establish trading limits. NW Natural's outstanding financial derivatives at December 31, 2024 mature by November 1, 2027.
We could become materially exposed to credit risk with one or more of our counterparties if natural gas prices experience a significant increase. If a counterparty were to become insolvent or fail to perform on its obligations, we could suffer a material loss; however, we would expect such a loss to be eligible for regulatory deferral and rate recovery, subject to a prudence review. All of our existing counterparties currently have investment-grade credit ratings.
Fair Value
In accordance with fair value accounting, NW Natural includes non-performance risk in calculating fair value adjustments. This includes a credit risk adjustment based on the credit spreads of NW Natural counterparties when in an unrealized gain position, or on NW Natural's own credit spread when it is in an unrealized loss position. The inputs in our valuation models include natural gas futures, volatility, credit default swap spreads, and interest rates. Additionally, the assessment of non-performance risk is generally derived from the credit default swap market and from bond market credit spreads. The impact of the credit risk adjustments for all financial derivatives outstanding to the fair value calculation was $0.3 million at December 31, 2024. As of December 31, 2024 and 2023, the net fair value was a liability of $81.6 million and a liability of $115.2 million, respectively, using
significant other observable, or Level 2, inputs. No Level 3 inputs were used in our derivative valuations during the years ended December 31, 2024 and 2023.
NWN Water Interest Rate Swap Agreement
In January 2023, NWN Water entered into an interest rate swap agreement with a major financial institution for $55.0 million that effectively converted variable-rate debt to a fixed rate of 3.80%. Interest payments made between the effective date and expiration date are hedged by the swap agreement. The interest rate swap agreement expires in June 2026, along with the variable-rate debt.
Unrealized gains related to the interest rate swap agreement are recorded in AOCI on the consolidated balance sheet and totaled $0.2 million and $0.2 million, net of tax, as of December 31, 2024 and 2023, respectively. Realized gains or losses occur as a result of monthly swap settlements. Gains of $0.9 million were reclassified from AOCI to net income during each of the years ended December 31, 2024 and 2023. The estimated amount of gains recorded in AOCI as of December 31, 2024 that are expected to be reclassified to net income within the next twelve months is $0.1 million.

Total fixed charges under capacity purchase agreements were $85.1 million for 2024, $87.0 million for 2023, and $90.2 million for 2022, of which $8.9 million, $8.2 million, and $8.3 million, respectively, related to capacity releases which third parties paid directly to the related pipelines. In addition, per-unit charges are required to be paid based on the actual quantities shipped under the agreements. In certain take-or-pay purchase commitments, annual deficiencies may be offset by prepayments subject to recovery over a longer term if future purchases exceed the minimum annual requirements.
RNG Purchase Agreements
NW Natural Renewables is an unregulated subsidiary of NW Holdings established to pursue investments in RNG activities. NW Natural Renewables, through its subsidiary Ohio Renewables, executed agreements with a subsidiary of EDL, a global producer of sustainable distributed energy, to secure RNG supply from two production facilities that are designed to convert landfill waste gases to RNG. This arrangement consists of a development agreement, an exclusive use agreement, a purchase agreement, and various guarantees.
Under the development agreement, the EDL subsidiary is responsible for the development and construction of the facilities and Ohio Renewables is committed to make payments of approximately $25 million per facility to the EDL subsidiary upon satisfaction of certain conditions. The first facility was completed and commenced delivery of RNG to Ohio Renewables in September 2024. Upon reaching this milestone, Ohio Renewables paid $26.0 million to the EDL subsidiary. The second facility was completed and commenced delivery of RNG to Ohio Renewables in December 2024 at which point Ohio Renewables made an additional payment of $25.4 million to the EDL subsidiary. The payments were recorded as long-term prepaid assets and will be amortized based on the volumes delivered over the life of the agreement.
Under the purchase agreement, Ohio Renewables and the subsidiary of EDL executed agreements for Ohio Renewables to purchase up to an annual specified amount of RNG produced by the EDL facilities over a 20-year period at a contractually specified price. We currently estimate the amount of RNG purchases (not included in the table above) from both facilities based on prices and quantities specified in the agreements to be as follows: approximately $18.9 million in 2025, $18.9 million in 2026, $22.8 million in 2027, $22.8 million in 2028, $24.1 million in 2029 and $532.6 million thereafter.
NW Holdings entered into a guarantee on behalf of Ohio Renewables with EDL. Per the guarantee, NW Holdings unconditionally and irrevocably guarantees the timely payment and performance when due of all obligations of Ohio Renewables. NW Holdings has not recognized a liability for its obligations under the guarantee in accordance with ASC 460, Guarantees.
RNG Sale Agreements
2024 - 2026
Ohio Renewables has contracted to sell RNG produced by the EDL facilities up to certain specified volumes in each of calendar years 2024 through 2026 to an investment-grade counterparty. Upon each delivery of RNG, Ohio Renewables will purchase an equal quantity of natural gas without renewable attributes at the same delivery point. Ohio Renewables has separately contracted to sell the natural gas purchased from EDL to another counterparty also at the same delivery point upon receipt. Alongside these agreements, NW Holdings entered into a guarantee on behalf of Ohio Renewables. Per the guarantee, NW Holdings unconditionally and irrevocably guarantees the prompt payment of all present and future obligations of Ohio Renewables. NW Holdings has not recognized a liability for its obligations under the guarantee in accordance with ASC 460, Guarantees.
The guarantee specifies annual cap amounts on the aggregate liability covered by the Guarantee as follows:

17. ENVIRONMENTAL MATTERS
NW Natural owns, or previously owned, properties that may require environmental remediation or action. The range of loss for environmental liabilities is estimated based on current remediation technology, enacted laws and regulations, industry experience gained at similar sites, and an assessment of the probable level of involvement and financial condition of other potentially responsible parties (PRPs). When amounts are prudently expended related to site remediation of those sites described herein, NW Natural has recovery mechanisms in place to collect 96.7% of remediation costs allocable to Oregon customers and 3.3% of costs allocable to Washington customers.
These sites are subject to the remediation process prescribed by the Environmental Protection Agency (EPA) and the Oregon Department of Environmental Quality (ODEQ). The process begins with a remedial investigation (RI) to determine the nature and extent of contamination and then a risk assessment (RA) to establish whether the contamination at the site poses unacceptable risks to humans and the environment. Next, a feasibility study (FS) or an engineering evaluation/cost analysis (EE/CA) evaluates various remedial alternatives. It is at this point in the process when NW Natural is able to estimate a range of remediation costs
and record a reasonable potential remediation liability, or make an adjustment to the existing liability. From this study, the regulatory agency selects a remedy and issues a Record of Decision (ROD). After a ROD is issued, NW Natural would seek to negotiate a consent decree or consent judgment for designing and implementing the remedy. NW Natural would have the ability to further refine estimates of remediation liabilities based upon an approved remedial design.
Remediation may include treatment of contaminated media such as sediment, soil and groundwater, removal and disposal of media, institutional controls such as legal restrictions on future property use, or natural recovery. Following construction of the remedy, the EPA and ODEQ also have requirements for ongoing maintenance, monitoring and other post-remediation care that may continue for many years. Where appropriate and reasonably known, NW Natural will provide for these costs in the remediation liabilities described below.
Due to the numerous uncertainties surrounding the course of environmental remediation and the preliminary nature of several site investigations, in some cases, NW Natural may not be able to reasonably estimate the high end of the range of possible loss. In those cases, the nature of the possible loss has been disclosed, as has the fact that the high end of the range cannot be reasonably estimated where a range of potential loss is available. Unless there is an estimate within the range of possible losses that is more likely than other cost estimates within that range, NW Natural records the liability at the low end of this range. It is likely changes in these estimates and ranges will occur throughout the remediation process for each of these sites due to the continued evaluation and clarification concerning responsibility, the complexity of environmental laws and regulations and the determination by regulators of remediation alternatives. In addition to remediation costs, NW Natural could also be subject to Natural Resource Damages (NRD) claims. NW Natural will assess the likelihood and probability of each claim and recognize a liability if deemed appropriate. Refer to "Other Portland Harbor" below.
Environmental Sites
The following table summarizes information regarding liabilities related to environmental sites, which are recorded in other current liabilities and other noncurrent liabilities in NW Natural's balance sheet at December 31:

Portland Harbor Site
The Portland Harbor is an EPA listed Superfund site that is approximately 10 miles long on the Willamette River and is adjacent to NW Natural's Gasco uplands site. NW Natural is one of over one hundred PRPs, each jointly and severally liable, at the Superfund site. In January 2017, the EPA issued its Record of Decision, which selects the remedy for the clean-up of the Portland Harbor site (Portland Harbor ROD). The Portland Harbor ROD estimates the present value total cost at approximately $1.05 billion with an accuracy between -30% and +50% of actual costs.
NW Natural's potential liability is a portion of the costs of the remedy for the entire Portland Harbor Superfund site. The cost of that remedy is expected to be allocated among more than one hundred PRPs. NW Natural is participating in a non-binding allocation process with other PRPs in an effort to resolve its potential liability. The Portland Harbor ROD does not provide any additional clarification around allocation of costs among PRPs; accordingly, NW Natural has not modified any of the recorded liabilities at this time as a result of the issuance of the Portland Harbor ROD.
NW Natural manages its liability related to the Superfund site as two distinct remediation projects, the Gasco Sediments Site and Other Portland Harbor projects.
GASCO SEDIMENTS. In 2009, NW Natural and Siltronic Corporation entered into a separate Administrative Order on Consent with the EPA to evaluate and design specific remedies for sediments adjacent to the Gasco uplands and Siltronic uplands sites. NW Natural submitted a draft EE/CA to the EPA in May 2012 and the EE/CA estimated the cost of potential remedial alternatives for this site. In March 2020, NW Natural and the EPA amended the Administrative Order on Consent to include additional remedial design activities downstream of the Gasco sediments site and in the navigation channel. Siltronic Corporation is not a party to the amended order. NW Natural is completing pre-design studies and has submitted a draft Basis of Design Report. These preliminary design steps do not include a cost estimate for cleanup. No remedial design is more likely than the EE/CA alternatives at this time, and NW Natural expects further design discussion and iteration with the EPA.
The estimated costs for the various sediment remedy alternatives in the draft EE/CA for the additional studies and design work needed before the cleanup can occur, and for regulatory oversight throughout the cleanup range from $55.2 million to $350 million. NW Natural has recorded a liability of $55.2 million for the Gasco sediment clean-up, which reflects the low end of the range. At this time, we believe sediments at the Gasco sediments site represent the largest portion of NW Natural's liability related to the Portland Harbor site discussed above.
In September 2023, the EPA approved the In Situ Stabilization and Solidification (ISS) Work Plan for the ISS field pilot study, which was successfully completed during the fall of 2023. Information obtained from the pilot study will be used to support remedial design of the Gasco sediments project.
OTHER PORTLAND HARBOR. While we believe liabilities associated with the Gasco sediments site represent NW Natural's largest exposure, there are other potential exposures associated with the Portland Harbor ROD, including NRD costs and harborwide remedial design and cleanup costs (including downstream petroleum contamination), for which allocations among the PRPs have not yet been determined.
NW Natural and other parties have signed a cooperative agreement with the Portland Harbor Natural Resource Trustee council to participate in a phased NRD assessment to estimate liabilities to support an early restoration-based settlement of NRD claims. One member of this Trustee council, the Yakama Nation, withdrew from the council in 2009, and in 2017, filed suit against NW Natural and 29 other parties seeking remedial costs and NRD assessment costs associated with the Portland Harbor site, set forth in the complaint. The complaint seeks recovery of alleged costs totaling $0.3 million in connection with the selection of a remedial action for the Portland Harbor site as well as declaratory judgment for unspecified future remedial action costs and for costs to assess the injury, loss or destruction of natural resources resulting from the release of hazardous substances at and from the Portland Harbor site. The Yakama Nation has filed two amended complaints addressing certain pleading defects and dismissing the State of Oregon. On the motion of NW Natural and certain other defendants the federal court has stayed the case pending the outcome of the non-binding allocation proceeding discussed above. NW Natural has recorded a liability for NRD claims which is at the low end of the range of the potential liability; the high end of the range cannot be reasonably estimated at this time. The NRD liability is not included in the aforementioned range of costs provided in the Portland Harbor ROD.
Gasco Uplands Site
A predecessor of NW Natural, Portland Gas and Coke Company, owned a former gas manufacturing plant that was closed in 1958 (Gasco site) and is adjacent to the Portland Harbor site described above. The Gasco site has been under investigation by NW Natural for environmental contamination under the ODEQ Voluntary Cleanup Program (VCP). It is not included in the range of remedial costs for the Portland Harbor site noted above. The Gasco site is managed in two parts, the uplands portion and the groundwater source control action.
NW Natural submitted a revised Remedial Investigation Report for the uplands to ODEQ in May 2007. In March 2015, ODEQ approved the Risk Assessment (RA) for this site, enabling commencement of work on the FS in 2016. A draft FS is currently anticipated to be submitted in 2024. NW Natural has recognized a liability for the remediation of the uplands portion of the site which is at the low end of the range of potential liability; the high end of the range cannot be reasonably estimated at this time.
In October 2016, ODEQ and NW Natural agreed to amend their VCP agreement for the Gasco uplands to incorporate a portion of the Siltronic property formerly owned by Portland Gas & Coke between 1939 and 1960 into the Gasco RA and FS. Previously, NW Natural was conducting an investigation of manufactured gas plant constituents on the entire Siltronic uplands for ODEQ. Siltronic will be working with ODEQ directly on environmental impacts to the remainder of its property.
In September 2013, NW Natural completed construction of a groundwater source control system, including a water treatment station, at the Gasco site. NW Natural has estimated the cost associated with the ongoing operation of the system and has recognized a liability which is at the low end of the range of potential cost. NW Natural cannot estimate the high end of the range at this time due to the uncertainty associated with the duration of running the water treatment station, which is highly dependent on the remedy determined for both the upland portion as well as the final remedy for the Gasco sediments site.
In December 2024, NW Natural submitted the Gasco uplands FS to ODEQ. The FS presents a set of remedial action alternatives and provides the basis for range of potential remedial costs for the site. The estimated costs for the alternative remedies range from $45.6 million to $358 million. NW Natural has recorded a liability of $45.6 million, which reflects the low end of the range.
Additionally, the EPA's Gasco sediments Administrative Order requires the integration of upland source controls with the sediment remedy. The selected sediment remedy is currently under separate design for the EPA. To comply with the source control integration requirement, some Gasco uplands work must be expedited. An Interim Remedial Action Measure (IRAM) for the Gasco uplands is the regulatory mechanism ODEQ has selected to accomplish that goal. As a result, the Gasco uplands FS also includes a separate cost range for the IRAM. The estimated costs for the IRAM range from $9.1 million to $78 million. NW Natural has recorded a liability of $9.1 million, which reflects the low end of the range.
Other Sites
In addition to those sites above, NW Natural has environmental exposures at three other sites: Central Service Center, Front Street and Oregon Steel Mills. NW Natural may have exposure at other sites that have not been identified at this time. Due to the
uncertainty of the design of remediation, regulation, timing of the remediation and in the case of the Oregon Steel Mills site, pending litigation, liabilities for each of these sites have been recognized at their respective low end of the range of potential liability; the high end of the range could not be reasonably estimated at this time.
FRONT STREET SITE. The Front Street site was the former location of a gas manufacturing plant NW Natural operated (the former Portland Gas Manufacturing site, or PGM). At ODEQ’s request, NW Natural conducted a sediment and source control investigation and provided findings to ODEQ. In December 2015, an FS on the former Portland Gas Manufacturing site was completed.
In July 2017, ODEQ issued the PGM ROD. The ROD specifies the selected remedy, which requires a combination of dredging, capping, treatment, and natural recovery. In addition, the selected remedy also requires institutional controls and long-term inspection and maintenance. Construction of the remedy began in July 2020 and was completed in October 2020. The second year of post-construction monitoring was completed in 2022 and demonstrated that the cap was intact and performing as designed. NW Natural has recognized an additional liability of $1.1 million associated with long-term monitoring and post-construction work.
OREGON STEEL MILLS SITE. Refer to “Legal Proceedings,” below.
Environmental Cost Deferral and Recovery
NW Natural has authorizations in Oregon and Washington to defer costs related to remediation of properties that are owned or were previously owned by NW Natural. In Oregon, a Site Remediation and Recovery Mechanism (SRRM) is currently in place to recover prudently incurred costs allocable to Oregon customers, subject to an earnings test. On October 21, 2019 the WUTC authorized an Environmental Cost Recovery Mechanism (ECRM) for recovery of prudently incurred costs allocable to Washington customers beginning November 1, 2019.
The following table presents information regarding the total regulatory asset deferred as of December 31:
| | | | | | | | | | | | | | |
| In thousands | | 2024 | | 2023 |
Deferred costs and interest(1) | | $ | 64,940 | | | $ | 57,758 | |
Accrued site liabilities(2) | | 159,954 | | | 121,575 | |
| Insurance proceeds and interest | | (47,062) | | | (50,764) | |
Total regulatory asset deferral(1) | | 177,832 | | | 128,569 | |
Current regulatory assets(3) | | 10,746 | | | 9,950 | |
Long-term regulatory assets(3) | | 167,086 | | | 118,619 | |
(1) Includes pre-review and post-review deferred costs, amounts currently in amortization, and interest, net of amounts collected from customers.
(2) Excludes 3.3% of the Front Street site liability as the OPUC only allows recovery of 96.7% of costs for those sites allocable to Oregon, including those that historically served only Oregon customers. Amounts excluded from regulatory assets were $36 thousand in 2024 and $53 thousand in 2023.
(3) Environmental costs relate to specific sites approved for regulatory deferral by the OPUC and WUTC. In Oregon, NW Natural earns a carrying charge on cash amounts paid, whereas amounts accrued but not yet paid do not earn a carrying charge until expended. It also accrues a carrying charge on insurance proceeds for amounts owed to customers. In Washington, neither the cash paid nor insurance proceeds received accrue a carrying charge. Current environmental costs represent remediation costs management expects to collect from customers in the next 12 months. Amounts included in this estimate are still subject to a prudence and earnings test review by the OPUC and do not include the $5.0 million tariff rider. The amounts allocable to Oregon are recoverable through NGD rates, subject to an earnings test. See "Oregon SRRM" below.
Oregon SRRM
Collections From Oregon Customers
Under the SRRM collection process, there are three types of deferred environmental remediation expense:
•Pre-review - This class of costs represents remediation spend that has not yet been deemed prudent by the OPUC. Carrying costs on these remediation expenses are recorded at NW Natural's authorized cost of capital. NW Natural anticipates the prudence review for annual costs and approval of the earnings test prescribed by the OPUC to occur by the third quarter of the following year.
•Post-review - This class of costs represents remediation spend that has been deemed prudent and allowed after applying the earnings test, but is not yet included in amortization. NW Natural earns a carrying cost on these amounts at a rate equal to the five-year treasury rate plus 100 basis points.
•Amortization - This class of costs represents amounts included in current customer rates for collection and is generally calculated as one-fifth of the post-review deferred balance. NW Natural earns a carrying cost equal to the amortization rate determined annually by the OPUC, which approximates a short-term borrowing rate.
In addition to the collection amount noted above, an order issued by the OPUC provides for the annual collection of $5.0 million from Oregon customers through a tariff rider. As NW Natural collects amounts from customers, it recognizes these collections as
revenue and separately amortizes an equal and offsetting amount of its deferred regulatory asset balance through the environmental remediation operating expense line shown separately in the operating expense section of the income statement.
NW Natural received total environmental insurance proceeds of approximately $150 million as a result of settlements from litigation that was dismissed in July 2014. Under a 2015 OPUC order which established the SRRM, one-third of the Oregon allocated proceeds were applied to costs deferred through 2012 with the remaining two-thirds applied to costs at a rate of $5.0 million per year plus interest over the following 20 years. NW Natural accrues interest on the Oregon allocated insurance proceeds in the customer’s favor at a rate equal to the five-year treasury rate plus 100 basis points. As of December 31, 2024, NW Natural has applied $105.7 million of insurance proceeds to prudently incurred remediation costs allocated to Oregon.
Environmental Earnings Test
To the extent NW Natural earns at or below its authorized Return on Equity (ROE) as defined by the SRRM, remediation expenses and interest in excess of the $5.0 million tariff rider and $5.0 million insurance proceeds are recoverable through the SRRM. To the extent NW Natural earns more than its authorized ROE in a year, it is required to cover environmental expenses and interest on expenses greater than the $10.0 million with those earnings that exceed its authorized ROE.
Washington ECRM
Washington Deferral
On October 21, 2019, the WUTC issued an order (WUTC Order) establishing the ECRM which allows for recovery of past deferred and future prudently incurred environmental remediation costs allocable to Washington customers through application of insurance proceeds and collections from customers. Environmental remediation expenses relating to sites that previously served both Oregon and Washington customers are allocated between states with Washington customers receiving 3.3% percent of the costs and insurance proceeds.
In accordance with the WUTC Order, insurance proceeds were fully applied to costs incurred between December 2018 and June 2019 that were deemed prudent. Remaining insurance proceeds will be amortized over a 10.5 year period ending December 31, 2029. As of December 31, 2024, approximately $4.1 million of proceeds have been applied to prudently incurred costs.
On an annual basis, NW Natural files for a prudence determination and a request to amortize costs to the extent that remediation expenses exceed the insurance amortization. After insurance proceeds are fully amortized, if in a particular year the request to collect deferred amounts exceeds one percent of Washington normalized revenues, then the excess will be collected over three years with interest.
Legal Proceedings
On October 11, 2024, NW Natural was added as a defendant to an ongoing lawsuit brought by Multnomah County in the Circuit Court for Multnomah Count, Oregon (County of Multnomah v. Exxon Mobil Corp., et. al., No.23-cv-25164) against more than a dozen oil and gas producers seeking damages relating to climate change impacts. The County asserts various causes of action, including negligence, fraud, trespass and public nuisance under Oregon law related to the refining, producing and/or marketing of fossil fuels. NW Natural is diligently defending against the claims.
On October 14, 2024, NW Natural and NW Holdings were named the defendants in a lawsuit filed in the Circuit Court for Multnomah County, Oregon (Blumm et. al. v. Northwest Natural Gas Company, 24-cv-48490), that is seeking class certification on behalf of all Oregon NW Natural Smart Energy-enrolled customers during the past approximately six years. The lawsuit alleges claims under Oregon's Unlawful Trade Practices Act and for breach of contract, with respect to NW Natural's Smart Energy program. The plaintiffs seek injunctive and equitable relief and damages. We are diligently defending against the claims.
NW Natural and NW Holdings are subject to claims and litigation arising in the ordinary course of business, including the matters discussed above. Although the final outcome of any of these legal proceedings cannot be predicted with certainty, including the matter relating to the Oregon Steel Mills site referenced below, NW Natural and NW Holdings do not expect that the ultimate disposition of any of these matters will have a material effect on their financial condition, results of operations, or cash flows. See also Part I, Item 3, “Legal Proceedings".
Oregon Steel Mills Site
In 2004, NW Natural was served with a third-party complaint by the Port of Portland (the Port) in a Multnomah County Circuit Court case, Oregon Steel Mills, Inc. v. The Port of Portland. The Port alleges that in the 1940s and 1950s petroleum wastes generated by NW Natural's predecessor, Portland Gas & Coke Company, and 10 other third-party defendants, were disposed of in a waste oil disposal facility operated by the United States or Shaver Transportation Company on property then owned by the Port and now owned by Evraz Oregon Steel Mills. The complaint seeks contribution for unspecified past remedial action costs incurred by the Port regarding the former waste oil disposal facility as well as a declaratory judgment allocating liability for future remedial action costs. No date has been set for trial. In August 2017, the case was stayed pending the outcome of the Portland Harbor allocation process or other mediation. Although the final outcome of this proceeding cannot be predicted with certainty, NW Natural and NW Holdings do not expect the ultimate disposition of this matter will have a material effect on NW Natural's or NW Holdings' financial condition, results of operations, or cash flows.
18. SUBSEQUENT EVENTS
Term Loan
On January 6, 2025, NW Holdings entered into a Term Loan Credit Agreement (the Term Loan Agreement), among NW Holdings, as borrower, certain lenders parties thereto, and U.S. Bank National Association, as Administrative Agent, pursuant to which NW Holdings borrowed a $50.0 million senior unsecured term loan (the Term Loan), the proceeds of which will be used for working capital needs and for general corporate purposes. The Term Loan is due and payable on April 6, 2026. NW Holdings may prepay the Term Loan without premium or penalty (other than customary breakage costs, if applicable). Amounts prepaid may not be reborrowed.
The Term Loan Agreement requires NW Holdings to cause its wholly owned subsidiary, NW Natural, to maintain credit ratings with S&P and Moody’s. NW Holdings must also notify the Administrative Agent and Lenders of any change in either NW Holdings' or NW Natural's S&P or Moody’s ratings. NW Holdings currently maintains ratings with S&P but not Moody's. NW Natural is not a party to and does not guarantee the Term Loan Credit Agreement.
The Term Loan bears interest at a per annum rate equal to the sum of (x) either (i) term SOFR with a one-, three- or six-month tenor, plus an adjustment of 0.10%, or (ii) the Alternate Base Rate, as defined in the 364-Day Credit Agreement, plus (y) the Applicable Margin, as defined in the Term Loan Agreement. The Applicable Margin is 0.90% per annum, for term SOFR loans, and 0.00% per annum, for Alternate Base Rate loans.
The Term Loan Agreement prohibits NW Holdings from permitting Consolidated Indebtedness to be greater than 70% of Total Capitalization, each as defined therein and calculated as of the end of each fiscal quarter of NW Holdings. Failure to comply with this financial covenant would entitle the lenders to accelerate the maturity of the Term Loan and all other amounts outstanding under the Term Loan Agreement. NW Holdings is in compliance with this covenant as of the date of this filing.
SiEnergy Acquisition
On January 7, 2025, NW Holdings acquired 100% of the issued and outstanding limited liability company interests of SiEnergy Operating, LLC (SiEnergy) from SiEnergy Capital Partners, LLC, from SiEnergy Capital Partners, LLC, an affiliate of Ridgewood Infrastructure, for approximately $271.1 million in cash and an assumption of $156.1 million of debt, subject to customary purchase price adjustments. SiEnergy serves approximately 70,000 residential and commercial customers in the greater metropolitan areas of Houston, Dallas, and Austin. Acquisition costs totaling $2.3 million in 2024 and $5.3 million in 2025 were expensed as incurred. The initial accounting for the business combination is incomplete due to the timing of the acquisition compared to when the financial statements were issued.
SiEnergy Credit Agreement
SiEnergy and its subsidiaries Si Investment Co, LLC (Si Investment Co), SiEnergy, L.P., Terra Transmission, LLC, SiEnergy Power Solutions, LLC, and SiEnergy GP, L.L.C. (collectively, the Loan Parties) are party to a Credit Agreement dated as of December 22, 2020 (the Original Credit Agreement) with ING Capital LLC, as administrative agent and L/C Issuer (as defined therein), and the lenders party thereto, as amended by Amendment No. 1 to Credit Agreement dated as of March 23, 2021 (the First Credit Agreement Amendment), Amendment No. 2 to Credit Agreement dated as of July 13, 2021 (the Second Credit Agreement Amendment), Amendment No. 3 to Credit Agreement dated as of July 11, 2022 (the Third Credit Agreement Amendment), and Amendment No. 4 to Credit Agreement dated as of December 22, 2023 (the Fourth Credit Agreement Amendment, and collectively with the First Credit Agreement Amendment, the Second Credit Agreement Amendment, the Third Credit Agreement Amendment, the Credit Agreement Amendments; and the Original Credit Agreement as amended by the Credit Agreement Amendments, the Amended Credit Agreement). Amounts under the Amended Credit Agreement are expected to be drawn on from time to time and used for general corporate purposes for the Loan Parties.
The Amended Credit Agreement provides Si Investment Co, as borrower, with access to the following credit facilities (collectively, the Facilities): (a) a term loan credit facility (the Delayed Draw Term Loan Facility), on a delayed draw basis, which had initial aggregate commitments, as amended, of $200,000,000, of which $33,300,000 remain in effect as of January 7, 2025; (b) a revolving credit facility (the Revolving Facility), in aggregate commitments (the Revolving Loan Commitments) as of January 7, 2025 of $5,000,000 including a letter of credit sublimit of $1,000,000; and (c) a term loan facility (the 2021 Term Loan Facility) with initial aggregate commitments of $17,900,000, none of which remains available as of January 7, 2025. As of January 7, 2025, the outstanding principal balance of the Delayed Draw Term Loan Facility is $151,116,760, the outstanding principal balance of the Revolving Facility is $5,000,000 and the outstanding principal balance of the 2021 Term Loan Facility is $0.
Under the Amended Credit Agreement, Si Investment Co is required to pay upfront fees, structuring fees, annual administrative fees, commitment fees, letter of credit fees and certain other fees. Loans extended under the Facilities bear interest at a per annum rate equal to the sum of (a) either (i) the Base Rate, as defined in the Amended Credit Agreement (the Base Rate), or (ii) term SOFR with a one-, three- or six-month tenor; plus (b) the Applicable Margin. The Applicable Margin is 0.750% with respect to Base Rate loans and 1.750% with respect to SOFR loans.
Loans borrowed under the Delayed Draw Term Loan Facility from time to time become funded term loans (Funded Term Loans), which are subject to required amortization, once per year. Si Investment Co. is required to make principal payments with respect
to Funded Term Loans in equal quarterly installments in an amount sufficient to amortize such loans over a period of 25 years. In addition, the Facilities are subject to certain mandatory prepayments, including in connection with certain asset sales or casualty or that result in Loan Parties’ receipt of certain insurance or condemnation proceeds. The Facilities mature on December 22, 2026.
Acquisition Bridge Facility
On January 7, 2025, NW Holdings entered into a 364-Day Term Loan Credit Agreement (the Acquisition Bridge Facility) among NW Holdings, as borrower, certain lenders parties thereto, and JPMorgan Chase Bank, N.A., as Administrative Agent, pursuant to which NW Holdings borrowed a $273.0 million senior unsecured term loan (the Bridge Loan), the proceeds of which were used to finance the SiEnergy acquisition, with any remaining proceeds to be used for working capital needs and for general corporate purposes.
The Bridge Loan is due and payable on January 6, 2026. Some or all of the Bridge Loan is subject to mandatory prepayment in the event of specified asset dispositions, casualty or condemnation events or the issuance by NW Holdings of certain public or private offerings of debt securities or equity interests, subject to certain exceptions, thresholds and reinvestment rights. NW Holdings may prepay the Bridge Loan without premium or penalty (other than customary breakage costs, if applicable). Amounts prepaid may not be reborrowed.
The Acquisition Bridge Facility requires NW Holdings to cause NW Natural, a wholly-owned subsidiary of NW Holdings, to maintain credit ratings with S&P and Moody’s. NW Holdings must also notify the Administrative Agent and Lenders of any change in the S&P or Moody’s ratings. NW Holdings currently maintains ratings with S&P but not Moody's. NW Natural is not a party to and does not guarantee the Acquisition Bridge Facility.
The Bridge Loan bears interest at a per annum rate equal to the sum of (x) either (i) term SOFR with a one-, three- or six-month tenor, plus an adjustment of 0.10%, or (ii) the Alternate Base Rate, as defined in the Acquisition Bridge Facility, plus (y) an Applicable Margin, as defined in the Acquisition Bridge Facility. The Applicable Margin is determined according to the Debt Rating, as defined in the Acquisition Bridge Facility, and ranges from 1.00% per annum to 1.50% per annum, for term SOFR loans, and 0.00% per annum to 0.50% per annum, for Alternate Base Rate loans.

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS
As of February 18, 2025, NW Holdings owned 100% of the outstanding common stock of NW Natural.
The following table sets forth information regarding compensation plans under which equity securities of NW Holdings are authorized for issuance as of December 31, 2024 (see Note 8 to the Consolidated Financial Statements):
| | | | | | | | | | | | | | | | | | | | |
| | | (a) | | (b) | | (c) |
| Plan Category | | Number of securities to be issued upon exercise of outstanding options, warrants and rights | | Weighted-average exercise price of outstanding options, warrants and rights | | Number of securities remaining available for future issuance under equity compensation plans (excluding securities reflected in column (a)) |
| Equity compensation plans approved by security holders: | | | | | | |
Long Term Incentive Plan (LTIP) (1)(2) | | 292,253 | | | n/a | | 65,153 | |
| Employee Stock Purchase Plan | | 41,838 | | | $ | 34.29 | | | 219,097 | |
| Equity compensation plans not approved by security holders: | | | | | | |
Executive Deferred Compensation Plan (EDCP)(3) | | 652 | | | n/a | | n/a |
Directors Deferred Compensation Plan (DDCP)(3) | | 27,052 | | | n/a | | n/a |
Deferred Compensation Plan for Directors and Executives (DCP)(4) | | 225,532 | | | n/a | | n/a |
| Total | | 587,327 | | | | | 284,250 | |
(1)Awards may be granted under the LTIP as Performance Share Awards, Restricted Stock Units, or stock options. Shares issued pursuant to Performance Share Awards and Restricted Stock Units under the LTIP do not include an exercise price, but are payable when the award criteria are satisfied. The number of shares shown in column (a) include 122,405 Restricted Stock Units and 169,848 Performance Share Awards, reflecting the number of shares to be issued as performance share awards under outstanding Performance Share Awards if target performance levels are achieved. If the maximum awards were paid pursuant to the Performance Share Awards outstanding at December 31, 2024, the number of shares shown in column (a) would increase by 169,848 shares, reflecting the maximum share award of 200% of target, and the number of shares shown in column (c) would decrease by the same amount of shares. No stock options or other types of award have been issued under the LTIP.
(2)The number of shares shown in column (c) includes shares that are available for future issuance under the LTIP as Restricted Stock Units or Performance Share Awards at December 31, 2024.
(3)Prior to January 1, 2005, deferred amounts were credited, at the participant’s election, to either a “cash account” or a “stock account.” If deferred amounts were credited to stock accounts, such accounts were credited with a number of shares of NW Natural (now NW Holdings) common stock based on the purchase price of the common stock on the next purchase date under our Dividend Reinvestment and Direct Stock Purchase Plan, and such accounts were credited with additional shares based on the deemed reinvestment of dividends. Cash accounts are credited quarterly with interest at a rate equal to Moody’s Average Corporate Bond Yield plus two percentage points, subject to a 6% minimum rate. At the election of the participant, deferred balances in the stock accounts are payable after termination of Board service or employment in a lump sum, in installments over a period not to exceed 10 years in the case of the DDCP, or 15 years in the case of the EDCP, or in a combination of lump sum and installments. Amounts credited to stock accounts are payable solely in shares of common stock and cash for fractional shares, and amounts in the above table represent the aggregate number of shares credited to participant's stock accounts. We have contributed common stock to the trustee of the Umbrella Trusts such that the Umbrella Trusts hold approximately the number of shares of common stock equal to the number of shares credited to all participants’ stock accounts.
(4)Effective January 1, 2005, the EDCP and DDCP were closed to new participants and replaced with the DCP. The DCP continues the basic provisions of the EDCP and DDCP under which deferred amounts are credited to either a “cash account” or a “stock account.” Stock accounts represent a right to receive shares of NW Holdings common stock on a deferred basis, and such accounts are credited with additional shares based on the deemed reinvestment of dividends. Effective January 1, 2007, cash accounts are credited quarterly with interest at a rate equal to Moody’s Average Corporate Bond Yield. Our obligation to pay deferred compensation in accordance with the terms of the DCP will generally become due on a predetermined date during a participant's service if elected by such participant or on retirement, death, or other termination of service, and will be paid in a lump sum or in installments of five, 10, or 15 years as elected by the participant in accordance with the terms of the DCP. Amounts credited to stock accounts are payable solely in shares of common stock and cash for fractional shares, and amounts in the above table represent the aggregate number of shares credited to participants' stock accounts. We have contributed common stock to the trustee of the Supplemental Trust such that this trust holds approximately the number of common shares equal to the number of shares credited to all participants' stock accounts. Historically, we have satisfied NW Holdings' stock contributions to the Supplemental Trust through purchases of NW Holdings stock in the open market. In 2023, the board of directors of NW Holdings authorized the original issuance of NW Holdings shares to the Supplemental Trust in satisfaction of such contributions. As of December 31, 2024, 343,977 shares remained available for issuance under current authorizations. The right of each participant in the DCP is that of a general, unsecured creditor of NW Natural.
