Northwest Natural Gas Signals Steady Growth Path

Northwest Natural Gas ((NWN)) has held its Q1 earnings call. Read on for the main highlights of the call.

Northwest Natural Gas struck a confident tone on its latest earnings call, highlighting steady earnings growth, robust customer additions and meaningful regulatory wins across its territories. While management acknowledged near‑term headwinds from higher depreciation, financing needs and softer water margins, they framed these as timing issues rather than structural problems, reinforcing a constructive outlook for long‑term shareholders.

Reaffirmed Earnings Guidance and Solid Start

Management reaffirmed full‑year 2026 EPS guidance of $2.95 to $3.15, underscoring confidence in the company’s trajectory despite a capital‑heavy plan. First‑quarter 2026 adjusted EPS rose to $2.33 from $2.28 a year ago, a 2.2% gain, as adjusted net income increased by $5.7 million, signaling healthy core performance even with incremental investment drag.

Rapid Customer Growth at C Energy

C Energy remained a primary growth engine, posting 16% organic customer growth in the quarter and building a backlog exceeding 250,000 future meters. Management expects C Energy to sustain 15% to 20% annual customer growth through 2030 and to provide roughly 10% to 15% of consolidated EPS in 2026, adding a faster‑growing leg to the company’s portfolio.

Water Segment Builds Scale Despite Near-Term Pressure

Northwest Natural Water delivered 4.1% overall customer growth, including 2.2% organic growth, backed by a backlog of more than 10,000 water and wastewater connections with about a quarter already in development. Management still expects water to contribute 10% to 15% of consolidated EPS in 2026 and to grow organically 2% to 3% annually through 2030, even as seasonality, higher O&M and depreciation weigh on near‑term margins.

Regulatory Progress Across Key Jurisdictions

The company reported important regulatory momentum, including a multi‑year rate case settlement in Washington that provides stepped revenue increases over three years with a 50‑50 capital structure and 9.5% allowed ROE. In Texas, C Energy filed a general rate case seeking a $12 million revenue increase, a 10.75% ROE, an 8.73% cost of capital and a sizable rate base step‑up, reinforcing earnings visibility from regulated returns.

MX3 Storage Project as Upside Catalyst

The MX3 storage expansion, a roughly $300 million FERC‑regulated project, would add 4 to 5 Bcf of fully contracted capacity under 25‑year agreements, representing long‑duration cash flow. Management targets a notice to proceed by 2027 and in‑service by 2029 and indicated that including MX3 in the plan could lift long‑term EPS growth guidance from 4% to 6% up to 5% to 7%.

Segment-Level Earnings Drivers

Core gas utility earnings benefited from new Oregon rates, with Northwest Natural Gas net income up $2.7 million in the quarter, helping offset investment‑related headwinds. C Energy added $0.08 to EPS driven by full‑quarter operations and strong organic growth, while water earnings were essentially flat but supported by higher revenues and acquisitions that should contribute more as regulatory recovery catches up.

Balanced Funding and Ample Liquidity

For 2026, management expects capital expenditures of $500 million to $550 million and plans to fund this through about $150 million of net long‑term debt and $40 million to $50 million of equity issued via its at‑the‑market program. With approximately $590 million of available liquidity, the company aims to cover its five‑year capex largely with operating cash flow supplemented by a balanced mix of debt and equity.

Reducing Regulatory Lag with New Mechanisms

To smooth earnings and reduce regulatory lag, Northwest Natural is pushing for multiyear rate frameworks and alternative mechanisms across its footprint, including GRIP‑style capital recovery in Texas and formula‑based rates in water utilities. These tools are intended to create a more linear earnings profile over time, aligning recovery more closely with ongoing investment and moderating the boom‑bust cycle of rate cases.

Regulatory Timing Risk in Oregon

Oregon remains a swing factor, as multiyear rate case rulemaking could drift into 2027, delaying the next wave of rate relief for the core gas utility. Management cautioned that Fair Act constraints and the existing regulatory cadence may allow rate base to grow faster than earnings recognition, potentially creating a catch‑up dynamic later in the planning period rather than smooth linear growth.

Depreciation and Financing as Near-Term Headwinds

Higher capital spending across the utilities is driving increased depreciation expense and greater financing needs, which partially offset earnings gains in the quarter. Management also noted that equity financing reduced gas utility EPS by $0.02, highlighting the trade‑off between funding growth and preserving per‑share earnings metrics in the near term.

Water Margins and M&A Slowdown

Water segment EPS was essentially flat as higher operating and depreciation costs absorbed much of the revenue increase, with Q1 seasonality further dampening results in what is typically a low‑demand period. Additionally, management described a slower acquisition market for water systems in 2026, suggesting that while organic growth remains solid, inorganic expansion will likely be more muted in the near term.

Macro Headwinds and Elevated Capex Plan

The company acknowledged a weaker economic backdrop in Oregon, including slower housing starts and softer macro indicators that could restrain customer growth in its home state utility. Combined with a sizable 2026 capex program of $500 million to $550 million, these conditions heighten sensitivity to financing costs and execution timing, even though management believes storage and other investments can support returns.

Forward-Looking Guidance and Growth Outlook

Looking ahead, management reiterated 2026 EPS guidance of $2.95 to $3.15 and maintained a long‑term EPS growth framework of 4% to 6%, with upside to 5% to 7% if MX3 proceeds on schedule. They expect C Energy and water to jointly supply about a quarter of consolidated EPS by 2026, underpinned by strong customer growth, expanding regulated rate bases and multiyear regulatory settlements that should progressively translate capital spending into earnings.

Northwest Natural Gas’s latest call painted a company steadily reshaping its earnings mix, with faster‑growing C Energy and water businesses complementing its core gas utility. While regulatory timing, higher depreciation, financing needs and a softer Oregon economy present near‑term challenges, solid customer growth, regulatory progress and the MX3 option leave management and investors with a generally constructive longer‑term outlook.
