The business in brief

read the 10-K →

What this business is and what moves its needle, from its own SEC filings.

Situation: Regulated utility. Returns are set by regulation on an approved rate base; the capital spending regulators approve becomes the growth, recovered through allowed rates.
What moves the needle: Operating margin has run about 19% through the cycle, a solid margin the cost base and competition set as much as the price does. That margin has stayed fairly steady relative to where it runs (15%–23% over the years), so unit growth and cost discipline, not a moving line, are the lever. Capital spending runs about 30% of sales, well above depreciation, so the return earned on what it sinks into that plant weighs as much as the margin. Read this kind of business on rate base and the allowed return. On its own account, the filing leans hardest on concentrated dependence, set against the numbers in what the filing emphasizes, below.
Is it a good business?: Return on capital has rarely cleared the cost of capital (median 6%, above 15% in 0 of 10 years). By owner earnings: roughly 10% of revenue reaches owners as cash, consistently. Modest returns here are the design, not a verdict: a regulated utility's prices are set by commission, so the questions are the return the regulator allows, how fast the invested base it earns that return on is growing, and the health of the relationship with the commissions that decide both — all of which live in the 10-K, not the multiple.

Every line is arithmetic on the company's filings, shown in full in the sections below.

Owner-earnings bridge

FY2021–FY2025cash-flow statement, SEC EDGAR →

Net income is the accountant's number; owner earnings is the cash an owner could take out. The walk between them, off the cash-flow statement, and whether the gap is widening or holding.

In fiscal 2025 the business earned $104M of owner earnings, the operating cash left after the $166M it takes just to hold its position. It put $301M more into growth; free cash flow, after that spending, was ($198M).

Owner earnings is the cash an owner could pull out without starving the business: operating cash less the maintenance capital it must spend to hold its position (here about $166M, roughly its depreciation, the rate its assets wear out). The other $301M of its capital spending is growth it chose, not upkeep it owed; charged only with the maintenance it must do, the business earns well more than the year's free cash flow shows.

A regulated utility reads differently here. What it spends above depreciation goes into rate base, where the commission lets it earn the allowed return and recover the capital, with interest, over decades — growth that is financed, not taken out of owners' pockets this year. So the truth sits between the bridge's two ends: owner earnings excuses the build-out entirely, free cash flow charges it entirely, and the scorecard's utility-plant figure shows how fast the base earning that return is compounding.

Maintenance capex is estimated as depreciation where a growing business invests above it; free cash flow is the figure the scorecard's free-cash margin reads.

Owner’s Scorecard

FY2025 10-K · source on SEC EDGAR →

The allowed return, earned and credited

Earned return on equity 7.3%

Below the typical allowed band

Median over 10 readable years · latest FY2025: 7.7% (net income $113M ÷ equity $1.5B)

What this means
A commission caps what a regulated utility may earn on shareholders' capital, so the question is not whether the return is high but whether the company actually earns what it is allowed — persistent under-earning means costs the regulator will not put in rates, and a return above the band usually means unregulated businesses in the mix. Read through the record, because a single year carries rate-case timing noise.
AFUDC in earnings —

Not enough data

What this means
The equity allowance for funds used during construction is not tagged in this filer's structured data — the construction credit, if any, lives in the 10-K's rate-matters note.

The invested base and the regulatory ledger

Net utility plant —

On subsidiary axes only

What this means
This filer reports its utility plant only on subsidiary or segment axes that the SEC's structured data drops, so the figure is withheld rather than approximated from consolidated property, which includes what the regulator sets no return on. The property schedule in the 10-K carries it.
Regulatory assets & liabilities $568M / $896M

Owes ratepayers

Regulatory assets $568M · regulatory liabilities $896M · net $328M liability position, as filed

What this means
The ledger of the regulatory relationship: assets are costs the commission has agreed the utility may collect from ratepayers in future rates, liabilities are amounts it must give back. Both are promises whose worth depends entirely on the commissions that made them — which is why they are shown as filed and never netted into earnings adjustments here.

Graham’s defensive tests · 3 of 5 met

Graham’s numerical criteria for the defensive investor (The Intelligent Investor, ch. 14), run on the filings. A floor of safety, not a buy signal; many fine modern businesses fail his strictest liquidity rules by design.

Adequate size Near

Revenue ≥ $2B · $1.3B

What this means
Big enough to weather a storm. Graham's 1972 floor was ~$100M of sales (≈ $700M today); we use a $2B revenue line as a conservative modern stand-in.
Strong liquidity —

Current ratio ≥ 2× (waived for utilities) · exempt

What this means
Graham exempted public utilities from this test: their working capital “takes care of itself” through the continuous bond-and-share financing of growth, so a thin current ratio is the industry's structure, not a warning. His substitute test — debt no more than twice book equity — is the next line.
Conservative debt Pass

Debt ≤ 2× equity (Graham's utility test) · $2.4B vs $1.5B equity

What this means
Graham's own substitution for public utilities: debt not exceeding twice the stock equity at book value, in place of the working-capital tests an industrial faces. A utility finances its plant with bonds by design; the question is whether the borrowing stays inside the equity behind it.
Earnings stability Near

A profit every year (10-yr record) · 1 loss year

What this means
Graham wanted earnings in each of the past ten years, the stability a defensive owner leans on.
Dividend record Pass

Uninterrupted dividends · paid every year (10)

What this means
An unbroken dividend was Graham's mark of durability. He wanted twenty years; the filings show about ten, and a single suspension breaks the streak. Non-payers, many fine modern compounders, fall outside his defensive net by design.
Earnings growth Pass

Earnings +33% over the record · +322%

What this means
At least a third more earnings than a decade ago, averaging three years at each end. Net income (not per-share), so stock splits don't distort it, buybacks and dilution show up in the share-count line instead.
Moderate price —

P/E ≤ 15 and P/E × P/B ≤ 22.5 · decided by the price

What this means
Graham's valuation gate, the wall he kept between a sound business and a sound investment. Three-year average earnings are $2.27/share (latest year $2.69), the averaged base the calculator's gate runs on, and book value is $35.04/share. Enter a price in “What the price implies” just below for the P/E, P/B, and whether it clears. But this is the rule Buffett outgrew: there's no hard P/E law, and a wonderful business can deserve a far richer multiple if the thesis holds, treat it as the bargain-hunter's floor, not a verdict on the price.

Durability & moat, 2016–2025

Whether the record’s returns held, and what the capital reinvested earned.

Profitable years 9 of 10

What this means
Lost money in 1 year(s), look at what happened there before trusting the average.
Return on capital ≥ 15% 0 of 9 yrs

What this means
A moat shows up as a high return on invested capital that holds year after year, not one good vintage.
Operating margin 20% → 18% (3-yr avg ends)

In the filing’s words Input costs rose and the filing says it recovered them in price — consistent with the margin holding here.

What this means
The recent-years average (18%) sits below the early years (20%), but the latest year (22%) is back near the early level: a cyclical trough dragging the window down, not a one-way slide. The through-cycle median is 19% — read it across the cycle, not on the dip.
Reinvestment, incremental ROIC 4%

What this means
Reinvested capital came back at only a modest incremental return — near the cost of capital, where extra growth adds little per dollar. The record shows whether it is a soft stretch or a thinning moat.
Owner earnings growth −5%/yr

What this means
Owner earnings shrank about 5% a year over the record.
Worst year 2023 · 15.4% op. margin

What this means
Stayed profitable even in its hardest year, the resilience that survives recessions.
Share count +4.4%/yr

What this means
The share count is rising, dilution works against you on a per-share basis.
Dividend record rising

What this means
Paid and raised the dividend across the record, the continuity Graham prized.
How management talks about it Owner’s terms

What this means
Returns have thinned, but the filing discusses it in an owner’s vocabulary rather than selling past it — candor about a hard stretch counts for more than an adjective.

All figures as filed; the source filing is linked above.

Cash on hand as of Jun 30, 2026 plus a year’s owner earnings comes to $128M against the $161M due in the twelve months after the Dec 31, 2025 schedule: about 80% of it, so the near maturities lean on refinancing or the rest of the year’s cash.

Maturity schedule extracted from the company’s Dec 31, 2025 annual report and reconciled to the balance-sheet debt.

How the cash was used, 2016–2025

Over the record, the business generated $2.0B of operating cash; how management split it reads as a reinvestor, most operating cash is plowed back into the business.

Reinvested$2.9B · 145%
Dividends$602M · 30%
Buybacks$3M · 0%

Returned to owners$605M
68% of the owner earnings the business produced over the span, $602M as dividends and $3M as buybacks.
Source of funding−$1.5B
Reinvestment and shareholder returns ran $1.5B beyond the operating cash the business generated, so the gap was financed off the balance sheet.
Average price paid for buybacks—
Buybacks ran $3M over the span, but the filings don't tag the share count needed to deduce the average price paid.
Net change in share count51.2%
The diluted count rose from 28M to 42M: issuance (stock pay, deals) outran any buybacks, so owners were diluted on net.
Dividend record$1.89/sh
Paid in 10 of the years on record, the per-share dividend growing about 0% a year. It was cut at least once along the way.
Return on what it retained—
Not read here: owner earnings are negative over the span, or the company returned nearly all its earnings rather than retaining them, so there is too little retained to measure a return on.

Buybacks are gross of stock issued to staff; the share-count line above is the net of that, the figure that decides whether owners gained. The average price paid blends a year of purchases (and any accelerated repurchase), so it is close, not exact. The record of where the cash went and on what terms.

Management, ownership & pay

read the proxy →

From the proxy: how much of the business the people running it own, and how they are paid, beside what the business earned for its owners in the same years.

Fiscal year	Chief executive	Pay, as filed	“Actually paid”	Owner earnings
2021	Mr. Anderson	$3.8M	$3.4M	$47M

2025	Mr. Anderson	$576k	$1.1M	$104M
2025	Mr. Palfreyman	$3.7M	$3.6M	$104M

Both pay figures are the company’s own, from the pay-versus-performance table its proxy statement files. “As filed” is the Summary Compensation Table total: salary, bonus, and equity awards at their value on the day of grant. “Actually paid” is the SEC’s prescribed recalculation, which re-marks those equity awards to what they became as they vested; it can swing far above or below the filed figure in either direction, and negative years occur.

The price

What a price has to assume.

What the price implies

reverse-DCF

Type today's close and see the owner-earnings growth you'd have to believe to justify it, beside what Northwest Natural has delivered.

Northwest Natural’s latest year shows negative owner earnings, the mark of a build-out: total capital spending outruns the cash the business throws off today. So the tool opens on the steady-state base (maintenance capex in place of the build-out spend), the cash it would earn at rest; clear the toggle below to read the latest year exactly as reported.

Today’s price $

Through the cycle, Northwest Natural earns about $128M on its 9.9% median owner-earnings margin. This year’s 8.0% margin runs below that; the reported figure may understate a lean year. Normalize, below, values the price on that through-cycle figure rather than the latest year.

Graham capped the multiple at 15×; Buffett and Munger let that rule go: a wonderful business can deserve 50× if the thesis holds. The gate marks the bargain-hunter's floor.

Graham measured a stock against the bond you could own instead, the heart of his margin of safety. Enter a price above to weigh the owner-earnings yield against this bond.

Free cash flow ($266M) on 42M shares outstanding, per the 10-Q cover, as of 2026-07-28; net debt $2.5B. The base opens on the steady-state figure (the latest year is negative on total capex mid-build-out); clear Steady-state to use the year as filed. Net of stock comp treats option pay as the expense it is. Capex ($479M) runs well above depreciation ($172M), so this is a build-out; Steady-state swaps total capex for maintenance (≈ depreciation), lifting the base to about $48M, the cash it would throw off if it stopped expanding. The dials set the multiple a growth belief justifies; the price, and every dollar on this page, is yours.
