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
Gross margin has run about 35% and operating margin about 18% through the cycle, a solid spread between what it charges and what the product costs to make. Capital spending runs about 44% 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 cyclicality & demand, 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 5%, above 15% in 0 of 10 years). By owner earnings: roughly 11% 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.

Where the cash went

ReinvestBuybacksDividendsAcquisitionsRetainedBeyond op. cash

Each year's outlays against its operating cash: the mix, and how it drifts. The hatched cap is spending beyond that year's operating cash — financed from the balance sheet or borrowing, not operations.

FY2016FY2025

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 $101M of owner earnings, the operating cash left after the $483M it takes just to hold its position. It put $713M more into growth; free cash flow, after that spending, was ($611M).

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 $483M, roughly its depreciation, the rate its assets wear out). The other $713M 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. The cash-flow statement also adds stock comp back as non-cash, but it is a real cost paid in shares; counted as the expense it is (less $9M), owner earnings is nearer $92M.

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

  • Below the typical allowed band
    Median over 10 readable years · latest FY2025: 4.4% (net income $151M ÷ equity $3.4B)
    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 8.1% · FY2022
    Last reported FY2022
    FY2022, the most recent year reported: equity AFUDC $14M
    What this means

    The construction credit the commission allows into earnings, read at the most recent year the filing data carries it — named, never passed off as current. A year without the line usually means construction paused, which is itself information.

The invested base and the regulatory ledger

  • Net utility plant $9.3B
    Growing ≈ 7.4%/yr
    Utility plant net of depreciation, as filed · FY2016→FY2025: $4.9B → $9.3B, ≈ 7.4%/yr
    What this means

    The closest filed figure to the rate base — the invested capital the commission sets the allowed return on. Its growth rate is the utility's reinvestment runway: under regulation, earnings power compounds roughly as fast as the base the return is earned on, funded by capital the regulator lets the company recover with interest. Rate base itself is not tagged in any structured filing, so this is the proxy, labeled as what it is.

  • Regulatory assets & liabilities $981M / $768M
    Owed recovery from ratepayers
    Regulatory assets $981M · regulatory liabilities $768M · net $213M asset 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 · 5 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 Pass
    Revenue ≥ $2B · $2.2B
    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) · $5.4B vs $3.4B 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 Pass
    A profit every year (10-yr record) · no losses
    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 · +70%
    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 $1.56/share (latest year $1.47), the averaged base the calculator's gate runs on, and book value is $33.03/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 10 of 10
    What this means

    Never lost money over the record, the earnings stability Graham insisted on.

  • Return on capital ≥ 15% 0 of 10 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 The margin has held, but the filing names price competition — the pressure is present even where the margin has absorbed it so far.

    What this means

    Through the cycle the operating margin held roughly steady — about 20% early, 18% lately, median 18%.

  • Reinvestment, incremental ROIC 5%
    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 −9%/yr
    What this means

    Owner earnings shrank about 9% a year over the record.

  • Worst year 2019 · 9.9% op. margin
    What this means

    Stayed profitable even in its hardest year, the resilience that survives recessions.

  • Share count +2.8%/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.

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

Rate cases, in the filing’s words

A regulated utility does not set its own price. It asks a commission for one, case by case, and the commission grants some part of it. Below are the proceedings this filing puts on the record, quoted verbatim, largest dollars first. Nothing here is computed; every figure is the filer’s own sentence.

  • PUCTrequested by the filer
    $2.8 billionreturn on equity10.4%
    “In November 2025, TNMP filed the TNMP Base Rate Review with the PUCT, requesting recovery of $2.8 billion of rate base, a requested ROE of 10.4%, and a 47.54% equity ratio.”

Sentences from the Regulatory Matters and Pending Proceedings disclosures and the MD&A of the latest 10-K, largest dollars first, at most six. “Granted” marks a sentence in which the commission itself is the subject of the approving verb; everything else renders as a request, never as a decided outcome. A return on equity is shown only where the filer states one between 8 and 13 percent — the same figure in these filings also carries equity ratios and fair-value returns, and a number that must be interpreted before it can be believed is not shown at all. Nothing here says whether a case is still pending: filings state timings that are already past by the time they are read.

From the company's latest filing.

How the cash was used, 2016–2025

Over the record, the business generated $5.1B of operating cash; how management split it reads as a reinvestor, most operating cash is plowed back into the business.

  • Reinvested$8.3B · 162%
  • Dividends$1.1B · 21%
  • Buybacks$112M · 2%
  • Returned to owners$1.2B

    67% of the owner earnings the business produced over the span, $1.1B as dividends and $112M as buybacks.

  • Source of funding−$4.4B

    Reinvestment and shareholder returns ran $4.4B beyond the operating cash the business generated, so the gap was financed off the balance sheet: debt rose from $2.4B to $5.4B.

  • Average price paid for buybacks

    Buybacks ran $112M over the span, but the filings don't tag the share count needed to deduce the average price paid.

  • Net change in share count38.8%

    The diluted count rose from 80M to 111M: issuance (stock pay, deals) outran any buybacks, so owners were diluted on net.

  • Dividend record$1.60/sh

    Paid in 10 of the years on record, the per-share dividend growing about 7% a year. It was never cut over the span.

  • Return on what it retained−35%

    Of the earnings it kept rather than paid out ($179M over the span), annual owner earnings (first three years vs last three) fell $63M, so each retained $1 gave back about 0.35 of yearly owner earnings. Buffett's test, run on owner earnings instead of market value.

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.

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. Owner earnings are the whole business's, from the record above, for the same fiscal years.

  • Insider ownership1.1%

    The stake all directors and executive officers hold together, per the 2026 proxy: skin in the game, the first thing Munger reads.

  • CEO pay ratio35:1

    What the chief earns for every dollar the median employee makes, per the 2026 proxy. A high ratio alone settles nothing; some businesses are genuinely top-heavy in scarce skill. A runaway figure is where Buffett starts asking whether the board is doing its job.

  • Stock-based compensation$9M

    The slice of the business handed to employees in shares in fiscal 2025, 0.4% of revenue, equal to 2.0% of operating profit. Buffett's oldest accounting fight: this is compensation, compensation is an expense, real whether or not the headline earnings admit it. One trap: the cash-flow statement adds SBC back, so the operating cash, and the owner earnings drawn from it, are flattered by exactly this amount; counted as the cost it is, what an owner keeps is lower.

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 TXNM Energy Inc. has delivered.

TXNM Energy Inc.’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.

$

Through the cycle, TXNM Energy Inc. earns about $237M on its 10.9% median owner-earnings margin. This year’s 4.7% 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’s price gate

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.

Against a high-grade bond: Graham’s yardstick bond yield%

Prefilled with the 10-year Treasury (4.71%, as of Aug 18, 2026). Edit it for today’s exact figure, or a AAA corporate yield.

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 ($502M) on 103M shares outstanding, per the 10-Q cover, as of 2026-07-24; net debt $5.4B. The if-converted diluted count is 111M, 8% above the shares outstanding: the dilution overhang (convertibles, options) a buyer inherits. 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 ($1.2B) runs well above depreciation ($501M), so this is a build-out; Steady-state swaps total capex for maintenance (≈ depreciation), lifting the base to about $179M, 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.
