Charting a Course for Sustained Prosperity: NW Natural's Strategic Ascent
Record-Breaking Financial Performance and Future Projections
Northwest Natural Gas Holdings celebrated a landmark year in 2025, achieving an unprecedented adjusted earnings per share (EPS) of $2.93, a notable increase from $2.33 in the previous year. This growth was fueled by the implementation of new rates in Oregon, a significant rise in organic customer acquisition, and strategic ventures into SiEnergy and the water utility sector. Looking ahead, the company has set an ambitious adjusted EPS guidance for 2026, ranging from $2.95 to $3.15, with the SiEnergy and water businesses projected to contribute approximately 25% of the total consolidated earnings.
Strategic Expansion in Gas Storage and Infrastructure Investment
A key initiative driving future growth is the planned MX3 gas storage expansion at the Mist facility, which is set to add 4–5 billion cubic feet (BCF) of storage capacity. This project, estimated to cost around $300 million, is underpinned by 25-year customer contracts guaranteeing a fixed 12.5% return on equity. With an anticipated in-service date by the end of 2029, this expansion is expected to elevate the company's long-term EPS growth target to 5%–7% upon receiving the notice to proceed, addressing critical regional reliability and capacity demands in the Pacific Northwest.
Regulatory Framework and Capital Expenditure Planning
The company's financial strategy includes a recently settled Oregon rate case and a proposed interim mechanism designed to incrementally increase customer rates by 1.5%, effective October 31, 2026. This measure aims to prevent substantial future rate hikes. Furthermore, Northwest Natural has outlined a long-term capital expenditure plan of $2.6–$2.9 billion through 2030, with approximately $500–$550 million allocated for 2026. Funding for these investments is expected to come from operating cash flow, around $150 million in new debt, and $40–$50 million from ATM equity issuances. The company also reaffirmed its commitment to consistent dividend growth, targeting a payout ratio between 55% and 65%.
Diversification Success: SiEnergy and Water Segment Contributions
The diversification strategy has yielded significant results, with SiEnergy exceeding expectations by contributing $0.33 per share to adjusted EPS in 2025, surpassing the projected $0.25–$0.30 range. The water segment also performed strongly, contributing $0.35 per share, driven by new rates and a late 2024 acquisition. These segments are critical to the company's growth trajectory, with SiEnergy expected to achieve 15%–20% customer growth annually through 2030 and contribute 10%–15% of consolidated EPS in 2026. The water segment is projected to deliver 2%–3% organic customer growth and contribute 10%–15% of consolidated EPS in 2026.
Funding Strategies and Shareholder Returns
The 2026 capital program will be financed through a combination of operational cash flow, approximately $150 million in net long-term debt, and $40 million to $50 million from equity issuance via the ATM program. In 2025, the company generated approximately $270 million in cash from operations, invested a record $467 million in capital expenditures, and spent nearly $340 million on acquisitions, closing the year with about $590 million in liquidity. A testament to its financial health, Northwest Natural boasts an impressive record of 70 consecutive years of dividend growth, with expectations for continued increases and a sustained payout ratio of 55%–65%.
