For a gas utility, the third quarter is usually the season of losses, and NW Natural is no exception. A year ago the company lost $0.73 per share in the July through September period on revenue of $164.7 million. The headline number matters less than its direction, though. When NW Natural reports before the open on November 5, the real question is whether the summer quarter shows the first measurable lift from the rate actions that led management to steer full-year 2026 earnings toward the upper half of its $2.95 to $3.15 range.

That guidance shift is the core of the setup. After simply reaffirming the range in its two prior reports, management used the second-quarter call to narrow its outlook to the upside for the first time. The full-year consensus of $3.04 sits just below the $3.05 floor of that upper half. The Street, in other words, has not fully bought the upgrade. A narrower year-over-year loss in the third quarter, together with a firm restatement of the top-half view, would push estimates toward management's number. Any softening of that language would be a clear setback, since the step-up was the main reason the tone improved.

The mechanics behind the upgrade should start showing up now. New Washington rates took effect August 1 after a settlement that delivered more than 80% of the requested revenue requirement, a 9.5% return on equity and a 50/50 capital structure. That outcome should contribute roughly two months of benefit this quarter. Management also pointed to the Oregon ARM to support a stronger second half, although the settlement came in at $13 million, below the original $15.6 million request. The counterweight is cost. Earnings at the core gas utility slipped in the second quarter as operations and maintenance expense, depreciation and financing costs all rose. If those costs keep growing faster than new rates, the second-half improvement will look smaller than promised.

Water is the swing factor to watch. Management acknowledged that first-half results ran modestly behind plan, citing integration costs on the platform, but noted that peak season was still ahead. The third quarter is that peak. Solid summer demand and steady customer growth, which ran at 3.4% over the trailing twelve months, would support the view that the shortfall was a matter of timing. Another miss would raise doubts about how much water can contribute to the plan. The renewable gas business remains a steadier story, with its backlog rising past 260,000 future meters and management still targeting 15% to 20% annual growth through 2030. Continued backlog gains would reinforce that thesis. On the MX3 storage project, the useful update would be any progress on the appeal filed with Oregon's land use board, since a notice to proceed by the end of 2027 is what would lift the company's long-term growth target to 5% to 7%.

Sentiment remains negative but has improved, with the bearish reading easing to 38.9% from 45.5% heading into the last report. The stock has edged up 0.7% since then while the S&P 500 slipped 0.8%. At $49.93, shares sit essentially on their 200-day moving average and in the upper part of the post-earnings range of $45.75 to $51.60. That leaves them close to, though not yet testing, a breakout. Investors appear cautiously receptive rather than convinced.

In the end, this report comes down to whether new Washington revenue and a strong water summer can outrun rising costs. If the seasonal loss narrows meaningfully and management stays committed to the top half of its range, the improving narrative holds. If cost pressure absorbs the rate relief, the upgrade will start to look premature.
