Northwest Natural's 2026 Guide and MX3: A Few Cents at Risk, a Bigger Growth Story in Play

2026 guidance points to steadier utility returns, not a near-term EPS breakout

This is the part of the story where common sense matters most. Northwest Natural is not set up for a flashy near-term EPS surprise. It just posted record adjusted EPS of $2.93 in 2025 and is guiding to $2.95 to $3.15 for 2026. In plain English, the market is mostly paying for a steady utility with a stable operating base and predictable earnings power, not a breakout year. That is the defensibility.

It also means bears can argue the upside is only a few cents over the next twelve months, especially as increased depreciation and financing costs press on margins.

But there is a bigger lever underneath the routine backdrop. Management is targeting 6% to 8% rate-base growth through 2030, which is the mechanism for turning today's spending into tomorrow's earnings base. If that translation works, investors are not chasing a one-quarter beat. They are underwriting a utility that can keep adding recoverable assets and earn a return on them over time.

Why the next few quarters matter

• Management is rolling out a coordinated regulatory strategy to reduce lag and make consolidated earnings more linear.
• Investors need proof that new investment is building a recoverable asset base, not just a heavier cost burden.
• The stock is more likely to rerate on earnings durability and recoverable plant than on a few cents of near-term EPS upside.

MX3 is the main growth variable because it could raise long-term EPS growth

What makes MX3 investable is not the headline. It is the business logic underneath it.

Why management says the project matters

Oregon is not just dealing with a local reliability issue. Management says MX3 addresses a projected 14-gigawatt generation shortfall by 2035 in the Pacific Northwest. In plain English, that points to a meaningful future power constraint, and gas storage can help balance the system when renewable output is weak. For a regulated utility, that matters because the project does not need viral demand. It needs a real reliability problem, a practical solution, and a path to cost recovery.

And the payoff is not trivial if that path gets approved. Management has said long-term EPS growth could step up from 4% to 6% to 5% to 7% once MX3 receives notice to proceed, expected by 2027. That is the part of the story investors may be underweighting: not just one project, but a potential shift to a higher-growth regime for recoverable capital.

Why scale matters in this story

This is also a scale story. Northwest Natural already operates across six states with 810,000 gas meters and 80,000 water connections. That matters for three reasons:

• It already has the customer footprint, operating base, and regulated cash-flow engine to absorb a large storage asset.
• It already has growth engines elsewhere, including Texas, which helps reduce timing risk if Oregon moves slowly.
• Utility assets of this kind are not easy to replicate. Once a project becomes part of regional reliability planning, the asset can look less like a standard utility holding and more like a scarce reliability asset.

Bull case and bear case

Bulls will focus on: - the projected 14-gigawatt generation shortfall by 2035, which gives MX3 real economic importance - the potential move to 5% to 7% long-term EPS growth after notice to proceed - a 2027 Oregon multiyear rate-case framework that could make the economics easier to underwrite

Bears will focus on: - timing: the better growth range arrives only after notice to proceed, expected by 2027 - regulatory lag: even a constructive framework may still mean negotiation and delay - execution risk: a large storage project can face cost overruns or permitting delays

My take: the bear case explains the delay risk, but the bull case better captures the asymmetry. If MX3 is confirmed and recoverable, investors are not just buying a safer utility. They are buying a scarce asset with a longer earnings runway.

The real investor debate is earnings power versus capital intensity

The real test now is simpler than the narrative around it: will each round of new spending show up later as cash in the register, or just as a bigger debt load?

That is the line investors need to watch over the next two or three quarters. Management has already said 2026 EPS should land at $2.95 to $3.15, while the company plans $2.6 billion to $2.9 billion of capex through 2030. It also flagged that ongoing investment has already lifted depreciation and financing costs. That is the whole debate in one frame. A utility can spend its way into future earnings, or it can spend its way into a heavier burden and a slower stock.

What durable earnings power would look like

The clearest sign would be a more linear earnings progression, not just a lumpy post-approval jump. Management is pushing a coordinated regulatory strategy to cut regulatory lag and make consolidated earnings more predictable. If that is working, investors should start seeing healthier earnings quality inside the guided range, not just a hopeful step-up after MX3 receives a notice to proceed.

There is also a balance-sheet test here. The company said capital needs will be funded through operating cash flow, debt, and ATM equity issuances, while also maintaining $590 million of liquidity and investment-grade credit ratings. That is not a red flag by itself. But if financing costs keep rising and other growth engines do not help offset the heavier interest burden, the market may stop rewarding capex and start focusing more on leverage.

Why Texas and water matter to the argument

This is where scale becomes useful. Texas operations delivered 16% organic customer growth, while the water business has more than 10,000 connections in backlog in Texas. Those segments matter because they can help show that NW Natural is not dependent on one project. If faster-growing lines keep contributing earnings while Oregon moves at its own pace, the company has a better chance of turning infrastructure spending into durable EPS growth.

What to watch now

Confirmation signals - 2026 earnings track toward the $2.95 to $3.15 range with no obvious deterioration in earnings quality. - Management's coordinated regulatory strategy continues to smooth earnings and reduce lag. - Texas and water keep acting as cushions, with 16% organic customer growth and more than 10,000 connections in backlog.

Invalidation signals - Ongoing investments lift depreciation and financing costs without matching earnings follow-through. - Funding leans too heavily on debt and ATM equity issuances while growth assets remain unresolved. - Oregon timing slips and the market starts pricing a longer wait for the MX3 growth step.
