Business Overview: A Storied History of Adaptation and Expansion

Northwest Natural Holding Company traces its roots back to 1859, when it was founded as the Portland Gas Light Company. In 1910, the company was incorporated as Portland Gas & Coke Company. Over the decades, the company has undergone several transformations, adapting to changing market dynamics and customer needs. A significant transition occurred in the 1950s when the company navigated the shift from manufactured gas to natural gas.

In 1997, the company rebranded as Northwest Natural Gas Company (NW Natural), reflecting its growing natural gas distribution business. During the Great Recession, NW Natural demonstrated resilience by maintaining its focus on safety and reliability for customers despite economic challenges.

In 2018, the company reorganized into a holding company structure, forming Northwest Natural Holding Company as the parent entity. This strategic move allowed the company to diversify its operations beyond its core natural gas distribution business, paving the way for its expansion into the water utility and renewable natural gas (RNG) sectors.

The 2010s marked a period of significant diversification for NW Holdings. In 2019, the company launched NW Natural Renewables to invest in renewable natural gas projects. This was followed by the acquisition of Avion Water Company in 2021, further expanding its water utility operations.

Throughout its history, NW Holdings has maintained investment-grade credit ratings and a balanced capital structure to support ongoing infrastructure investments. The company's natural gas distribution business has consistently earned authorized returns on equity from state regulators in Oregon and Washington, underscoring its strong regulatory relationships.

Today, NW Natural Holdings' natural gas distribution segment remains its largest business, serving approximately 806,000 meters across Oregon and southwestern Washington. The company has built a reputation for reliable service, safety, and environmental stewardship, making strategic investments to modernize its infrastructure and reduce emissions.

Recognizing the importance of diversification, NW Natural Holdings has also made significant strides in expanding its water and wastewater utility operations through its NW Natural Water subsidiary. Since 2018, the company has completed several strategic acquisitions, growing its water customer base to over 190,000 people across six states.

Most recently, in 2025, NW Natural Holdings announced the acquisition of SiEnergy, a rapidly growing natural gas utility serving the greater metropolitan areas of Houston, Dallas, and Austin, Texas. This transformative move further diversifies the company's geographic footprint and provides a new avenue for growth.

Financials: A Balanced Approach to Capital Allocation

NW Natural Holdings' financial performance has been relatively stable, with the company reporting net income of $78.9 million, or $2.03 per share, for the full year 2024. The company's revenue for the same period reached $1.15 billion. Operating cash flow for 2024 was $200.3 million, while free cash flow was negative $194.1 million.

The company's capital allocation strategy has been well-balanced, with a focus on both organic and inorganic growth. In 2024, NW Natural Holdings invested $394.4 million in its utility systems, primarily to support safety, reliability, and technology improvements. The company has also been active in the mergers and acquisitions space, deploying $30 million for water and wastewater utility acquisitions in 2024.

NW Natural Holdings' balance sheet remains strong, with a debt-to-capital ratio of 58.1% as of December 31, 2024. The company's credit ratings from S&P and Moody's are A- and Baa1, respectively, reflecting its financial discipline and prudent risk management. The debt-to-equity ratio stands at 1.39x, while the current ratio is 0.86x and the quick ratio is 0.69x.

Looking ahead, the company has provided guidance for 2025 adjusted earnings in the range of $2.75 to $2.95 per share, with a long-term earnings growth target of 4% to 6% per annum. This guidance factors in the expected contributions from the recently acquired SiEnergy business, as well as continued growth in the company's water and renewable natural gas operations.

For 2025, NW Natural Holdings expects consolidated capital expenditures to be in the range of $450 million to $500 million. The company has increased its consolidated CapEx range to $2.5 billion to $2.7 billion through 2030, representing a nearly 40% increase from their previous trajectory. Additionally, NW Natural Holdings' utilities combined annual rate base growth target has increased from 5% to 7% to 6% to 8%.

Segment Performance: Diversification Drives Resilience

Natural Gas Distribution (NGD): NW Natural's natural gas distribution business remains the core of the company's operations, accounting for the majority of its revenue and earnings. In 2024, the NGD segment reported a $26.3 million increase in utility margin, driven primarily by new customer rates in Oregon. The company has also made significant investments in its distribution infrastructure to enhance safety and reliability.

The NGD segment serves residential, commercial, and industrial customers in Oregon and southwest Washington, with approximately 88% of customers 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.

In 2024, NGD net income was $77.1 million, with a diluted EPS of $1.98 for the NGD segment. This decrease from the prior year was primarily due to a regulatory disallowance, regulatory lag, higher pension costs, lower interest income, and higher depreciation expense, partially offset by an increase in NGD margin driven by new customer rates in Oregon, amortization of deferred balances, and customer growth.

Northwest Natural Water (NW Natural Water): NW Natural's water and wastewater utility business has been a key driver of growth in recent years. In 2024, the water segment contributed to a $4.4 million increase in net income, reflecting both organic and inorganic expansion. The company continues to pursue strategic acquisitions to scale its water operations, which now serve over 190,000 people across six states.

For Northwest Natural Water, the company expects water and wastewater rate base to grow 10% to 15% from 2025 to 2027, with net income growing at a similar pace.

Northwest Natural Renewables (NW Natural Renewables): The company's renewable natural gas (RNG) business, housed under NW Natural Renewables, has also been an area of focus. In 2024, the company's first two RNG facilities with EDL went into operation, providing steady cash flows and earnings. NW Natural Renewables is poised to benefit from growing demand for renewable energy solutions.

Other Investments: NW Natural Holdings' "Other" segment includes the company's interstate natural gas storage activities, asset management services, and holding company operations. This segment contributed $11.9 million in net income in 2024, highlighting the diversification of the company's business model.

The Other segment at NW Holdings had a net loss of $10.1 million in 2024. The decrease at the NW Holdings level was driven by acquisition costs related to SiEnergy and higher interest expense at the holding company, partially offset by an increase in net income from water and wastewater subsidiaries.

Geographic Markets and Growth Projections

NW Natural Holdings operates primarily in the Pacific Northwest, serving customers in Oregon and southwest Washington. The company's recent acquisition of SiEnergy, now rebranded as C Energy, marks a significant expansion into the Texas market.

For C Energy, NW Natural Holdings anticipates total meter growth of approximately 20% over 2024 levels, translating to rate base growth of 20% to 25% and net income growth of 32% to 37% compounded annually from 2025 to 2027. This acquisition is expected to be a key driver of the company's overall growth, with NW Natural Holdings projecting 2% to 2.5% customer growth from 2025, largely driven by 20% or higher customer growth from C Energy.

Industry Trends and Competitive Landscape

The natural gas distribution industry has seen a compound annual growth rate (CAGR) of around 4-6% in recent years, driven by customer growth and rate base investments. NW Natural Holdings is well-positioned to capitalize on this trend, with its target long-term EPS growth rate aligning with industry averages.

Risks and Challenges

While NW Natural Holdings has demonstrated resilience and adaptability, the company faces several risks and challenges that warrant consideration:

1. Regulatory Environment: As a regulated utility, NW Natural Holdings is subject to the decisions and policies of various state public utility commissions, which can have a significant impact on the company's operations and financial performance.

2. Capital Expenditure Requirements: Maintaining and upgrading the company's vast natural gas and water distribution infrastructure requires substantial capital investments, which could put pressure on the company's financial resources.

3. Environmental Regulations: Evolving environmental regulations, particularly around greenhouse gas emissions and water quality standards, could necessitate additional investments and operational changes for the company.

4. Competitive Landscape: NW Natural Holdings faces competition from alternative energy sources, such as electricity and renewable energy, which could impact the demand for natural gas and the company's ability to attract and retain customers.

5. Integration Risks: The successful integration of acquired businesses, such as SiEnergy, will be crucial in realizing the anticipated synergies and growth opportunities.

Despite these challenges, NW Natural Holdings' diversified business model, strong balance sheet, and prudent management team position the company well to navigate the evolving utility landscape and deliver sustainable growth for its shareholders.

Leadership Transition

In January 2025, NW Natural Holdings announced that CEO David Anderson will be retiring in April 2025, and Justin Palfreyman will succeed him as the new CEO. This planned transition is expected to provide continuity in the company's strategic direction while bringing fresh perspectives to its leadership.

Liquidity and Capital Resources

NW Natural Holdings maintains a strong liquidity position to support its operations and growth initiatives. As of December 31, 2024, the company had cash and cash equivalents of $38.5 million. Additionally, NW Natural Holdings has access to substantial credit facilities, including a $200 million sustainability-linked credit agreement at the holding company level and a $400 million sustainability-linked credit agreement for NW Natural Gas.
