Texas growth now carries the story

01 Running thesis

A Northwest utility leans on Texas

NWN is a slow, regulated utility with a faster growth leg in Texas. The old center of the company is gas distribution in Oregon and Washington. That business is steady, but it is mature and depends on regulators approving fair rates.

The bull case got stronger in Q1 2026. C Energy, reported as SiEnergy in the filing, grew its backlog to more than 250,000 future meters. Management also said it expects 15% to 20% annual customer growth in that Texas gas business through 2030. That gives NWN a clear place to spend capital and grow rate base, which is the asset base regulators allow it to earn on.

The Texas rate case is now the key test. C Energy asked the Railroad Commission of Texas for a $12 million revenue increase, a 10.75% return on equity, and the ability to use the GRIP mechanism, which can update rates between full rate cases. A good ruling would reduce lag between spending money and earning money. A weak ruling would hurt the growth story.

Finn's view stays cautious because this is still a capital-heavy utility. Growth has improved, but the stock also depends on debt costs, regulator decisions, and whether Texas housing stays healthy enough to turn backlog into active customers.

May 2026▲Q1 2026 strengthened the Texas growth case. C Energy backlog rose above 250,000 future meters, and the Texas rate case became a defined catalyst with a $12 million revenue request and a 10.75% return on equity.
Aug 2025▲The Oregon rate case settlement reduced risk in the legacy gas utility. At the same time, the Texas backlog reached more than 217,000 future meters and was running ahead of plan.
May 2025▲NWN showed that C Energy and Water were becoming real earnings contributors. The Hughes Gas Resources deal added scale to Texas and lifted the contracted customer backlog above 200,000.
Feb 2025▲The C Energy acquisition closed and shifted the story toward a more diversified utility. Management raised the combined utility rate base growth target to 6% to 8% and lifted the capital plan through 2030.
Nov 2024→The initial thesis balanced steady regulated gas cash flows against Oregon regulatory risk. Water acquisitions and renewable natural gas projects offered growth options, but execution risk was still high.
02 Business model

Rates, pipes, meters, and returns

Most of NWN's money comes from regulated utilities. It builds and maintains gas, water, and wastewater systems. Regulators then decide what customers can be charged and what return the company can earn on its allowed rate base.

That model can be steady, but it is not automatic. If NWN spends money before rates catch up, earnings can lag. If a regulator rejects part of the investment, shareholders can lose value. The Oregon settlement in 2025 helped calm one concern, so the bigger watch item has moved to Texas.

NWN also owns smaller related businesses. Renewable natural gas projects sell output under long-term, fixed-price contracts with investment-grade buyers. Gas storage earns from storage services and could grow if the MX3 project moves ahead.

MX3 is a possible upside case, not the base case. Management described it as a $300 million FERC-regulated gas storage expansion that could add 4 to 5 Bcf of capacity under 25-year agreements. Management said it is not in the current 4% to 6% long-term EPS growth guidance, but could lift that range to 5% to 7% after a notice to proceed.

03 Product portfolio

What NWN sells

Cash cow

Oregon and Washington gas utility

This is the main legacy business. It serves residential, commercial, and industrial gas customers and gives NWN most of its current revenue.

Growth engine

Texas gas utility

C Energy, reported as SiEnergy, serves customers around Houston, Dallas, and Austin. Its backlog above 250,000 future meters is the main reason the growth outlook improved.

Growth engine

Water and wastewater

NWN Water serves communities across several states. Management expects this business to contribute about 10% to 15% of 2026 consolidated EPS.

Option

Renewable natural gas

NWN develops renewable natural gas projects, mainly from landfill gas. The goal is stable contract revenue rather than betting on volatile environmental credit prices.

Option

Gas storage

The company owns regulated storage assets, including Mist. MX3 could become a larger earnings driver if it receives a notice to proceed.

04 Business segments

Revenue still comes from NW Natural

NW Natural89%flat
SiEnergy6%growing fast
NWN Water3%modest
Other2%modest

Segment shares use Q1 2026 operating revenue from the Form 10-Q. The mix is still concentrated in NW Natural, even though the faster growth is in Texas and Water.

05 Risk factors

What could break the thesis

Texas rate case disappoints

High impact · Medium odds

C Energy asked for a $12 million revenue increase and a 10.75% return on equity. It also wants the GRIP mechanism so rates can update more quickly after capital spending. If regulators approve much less, Texas growth could look less valuable.

We watchThe Railroad Commission of Texas decision expected in Q4 2026, especially the allowed return on equity and GRIP treatment.

Backlog does not become customers

High impact · Medium odds

The Texas gas backlog is above 250,000 future meters, but backlog is not the same as paying customers. A sharp slowdown in Texas housing could delay new meter hookups. That would slow rate base growth and weaken the long-term EPS target.

We watchQuarterly updates on C Energy active customers, new meter additions, and the future meter backlog.

Capital needs outrun cash flow

Medium impact · Medium odds

Utilities spend a lot before they recover that money through rates. NWN is also expanding in Texas, Water, and possible storage projects. If debt costs stay high or equity issuance grows, per-share gains could be muted.

We watchCapital expenditure guidance, debt levels, equity issuance under the ATM program, and interest expense.

MX3 slips or fails to proceed

Medium impact · Medium odds

Management said MX3 is not in the current 4% to 6% long-term EPS growth guidance. It is the main named path to a possible 5% to 7% long-term range. If the project is delayed or canceled, that upside may not arrive.

We watchA formal notice to proceed for MX3 and any updated long-term EPS growth guidance.

Legacy regulation turns tougher again

Medium impact · Low odds

The Oregon settlement helped stabilize the older gas business, but this area still depends on regulator support. Past disallowances show that not every investment is guaranteed to be recovered. A renewed dispute could hurt earnings and investor trust.

We watchOregon and Washington rate orders, allowed return on equity, and any disallowed rate base.
06 Quick answers

In one breath

What does Northwest Natural Holding Company do?

NWN owns regulated gas, water, and wastewater utilities. Its largest business serves gas customers in Oregon and Washington, while its fastest-growing gas platform is in Texas.

Why is Texas important for NWN?

Texas gives NWN faster customer growth than its mature Northwest gas utility. C Energy had more than 250,000 future meters in backlog at Q1 2026, and management expects strong customer growth through 2030.

What is the biggest near-term catalyst for NWN stock?

The Texas rate case is the main catalyst. C Energy is asking for a $12 million revenue increase, a 10.75% return on equity, and GRIP treatment to reduce future regulatory lag.

Is NWN mainly a dividend utility or a growth utility?

It is still more of a regulated utility than a fast growth stock. The growth story is improving because of Texas gas, Water, and possible MX3 storage upside, but the company remains capital intensive.
