The business in brief

read the 10-K →

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

What it is
Revenue is KMT (58%) and Distribution and Services (42%).
Situation
Cyclical. Margins collapse and recover repeatedly across the record; a single year, good or bad, misstates the through-cycle earning power.
What moves the needle
Operating margin has run about 7.7% through the cycle, a thin margin, where volume, cost discipline and the price it gets all bear on the result. The margin is cyclical, swinging between −19% and 15% over the years, so the through-cycle figure carries more than any single year — and the balance sheet at the trough more than the peak. Inventory runs near 14% of sales, so how fast it turns back into cash — and the risk of writing it down when demand softens — sits alongside the margin. On its own account, the filing leans hardest on supplier & input 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 4%, above 15% in 0 of 10 years). By owner earnings: roughly 10% of revenue reaches owners as cash, consistently. The cycle and the balance sheet decide this one; the worst year tells more than the median, and the rest is in the 10-K.

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

  • KMT+1.2%
    “KMT’s revenues for 2025 increased 1% compared to 2024 and operating income increased 3%, compared to 2024. The increase in revenues for 2025 was primarily due to higher term pricing in the coastal market and higher term and spot pricing in the inland market during the 2025 first half, partially offset by lower fuel rebills in both the inland and coastal markets.”

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 turned $355M of profit into $406M of owner earnings: more cash than the profit line showed, after the non-cash charges and the capital it put back in.

Owner earnings is the cash an owner could pull out without starving the business: operating cash less the capital it must spend to hold its position . 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 $18M), owner earnings is nearer $388M.

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 →

Will it survive?

  • Comfortable
    Operating income $496M ÷ interest expense $46M
    What this means

    Operating profit covers interest with the kind of margin Graham wanted for a defensive holding. Necessary, not sufficient, it says solvent, not cheap.

  • How heavy is the debt, net of cash? $833M · 1.7× operating profit
    Modest net debt
    Cash $79M − debt $912M
    What this means

    Netting $79M of cash and short-term investments against $912M of debt leaves $833M owed, about 1.7× a year's operating profit (1.8× on the gross debt, before the cash). Net debt is the leverage figure that matters: the cash is already set against the debt. Strategic or illiquid investments aren't counted here.

  • Not enough data
    What this means

    The filing data didn't include the inputs for this check.

Is it a good business?

  • Below average through the cycle
    10-yr median, range -7%–9%; 9% latest = NOPAT $374M ÷ invested capital $4.2B
    Industry peers: median 11%
    What this means

    The rate the business earns on the money tied up in it, Buffett's north star, because over time a stock tracks the ROIC beneath it. Above ~15% sustained hints at a moat; a return below the cost of capital (~8%) erodes value as a business grows rather than building it — the test Buffett weighs most. The headline is the median of the last 10 years (it ran 9% most recently), so one peak or trough year doesn't set the verdict. Asset-light businesses (R&D expensed, little capital) read artificially high, pair this with Owner Earnings.

  • Solid through the cycle
    10-yr median margin, range 4%–16%; latest $406M = operating cash $670M − maintenance capex $264M
    Industry peers: median 18%
    What this means

    What an owner could take out without starving the business: operating cash less the maintenance capital it must spend to hold its position — Buffett's owner earnings. That's 12% of revenue this year, a 10% median across 10 years. Treating stock comp as the real expense it is (less $18M of SBC) leaves $388M.

  • Cash-backed
    Cash from ops $670M ÷ net income $355M
    What this means

    How much of reported profit showed up as operating cash. Above 1× is reassuring; well below suggests earnings lean on accruals. One year is noisy, growth and working-capital swings distort it, and this is operating cash, not free cash. Watch the multi-year trend.

How is the cash used?

  • Returns about half
    Dividends + buybacks $354M ÷ Owner Earnings $406M — this fiscal year
    What this means

    Of $406M Owner Earnings, $354M (87%) went back to shareholders, $0 dividends, $354M buybacks. Net of $18M stock comp, the real buyback was about $337M. Returning most of it is the mark of a mature business with little left to reinvest at a high return; reinvesting most could mean a long runway, or empire-building. The split doesn't say which; the return earned on it (see ROIC) does. This year's proportion is 87%; across the record (2016–2025) it is 25%, the capital-allocation section below.

  • Investing or harvesting? 1.00×
    Maintaining
    Capex $264M ÷ depreciation & amortization as filed $264M
    What this means

    Descriptive, not a grade. Above ~1× means investing faster than assets wear out (growth, or, sustained for years, today's earnings carrying less depreciation than tomorrow's will). Below means spending less than it's wearing out (efficiency, or a melting asset base). The ratio won't tell you which; the filings will.

The promise and the pay packet

  • Is the buyback buying ownership, or mopping up? 0.5%
    The count is genuinely shrinking
    Stock compensation $18M (fiscal 2025), 0.5% of revenue · repurchases $354M · diluted shares -7.1% since 2022
    What this means

    Stock handed to employees is a real cost paid in the owner's own currency: it is charged against profit, but the shares it creates are permanent. Many companies repurchase stock at the same time, which looks like a return of capital and often is not — if the count barely moves, the cash merely cancelled the pay packet and bought the owner nothing. The three states worth telling apart are a count genuinely shrinking, a count standing still despite large repurchases, and a count rising because the issuance was never offset at all.

Graham’s defensive tests · 2 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 · $3.4B
    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 Near
    Current ratio ≥ 2× · 1.53×
    What this means

    Current assets at least twice current liabilities, near-term bills covered without touching the business. Strict by design: many cash-rich modern firms run leaner and miss it, holding their cushion in longer-dated securities.

  • Conservative debt Miss
    Debt ≤ working capital · $912M vs $371M WC
    What this means

    Graham's rule that borrowings not exceed net current assets. Capital-heavy and buyback-heavy firms routinely fail it, read it next to interest coverage, not alone.

  • Earnings stability Miss
    A profit every year (10-yr record) · 2 loss years
    What this means

    Graham wanted earnings in each of the past ten years, the stability a defensive owner leans on.

  • Dividend record
    Uninterrupted dividends · no dividend line tagged in the data
    What this means

    An unbroken dividend was Graham's mark of durability. This record carries no dividends-paid line in any year — common for partnerships, whose distributions file under tags the chain doesn't read — so the criterion is withheld rather than judged on silence.

  • Earnings growth Pass
    Earnings +33% over the record · +62%
    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 $5.46/share (latest year $6.72), the averaged base the calculator's gate runs on, and book value is $64.02/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 8 of 10
    What this means

    Lost money in 2 year(s), look at what happened there before trusting the average.

  • 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 8% → 13% (3-yr avg ends)
    What this means

    Through the cycle the operating margin widened — about 8% early to 13% lately, median 7% — pricing power intact or improving.

  • Reinvestment, incremental ROIC returns capital
    What this means

    The capital base barely grew: this business returns cash through dividends and buybacks rather than reinvesting. Judge it on the cash returned, not on compounding.

  • Owner earnings growth +11%/yr
    What this means

    Owner earnings grew about 11% a year over the record.

  • Worst year 2020 · −19.4% op. margin
    What this means

    Operations went underwater in 2020, understand why before trusting the good years.

  • Share count +0.5%/yr
    What this means

    Roughly flat share count, little dilution, little buyback.

  • How management talks about it Owner’s terms
    What this means

    The record and the register agree: capital is compounding and the filing reasons in an owner’s terms — per-share value, return on capital, the long term — not a promoter’s.

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

From the company's latest filing.

How the cash was used, 2016–2025

Over the record, the business generated $4.7B of operating cash; how management split it reads as a reinvestor, most operating cash is plowed back into the business.

  • Reinvested$2.4B · 51%
  • Buybacks$667M · 14%
  • Retained (debt / cash)$1.6B · 34%
  • Returned to owners$667M

    25% of the owner earnings the business produced over the span, $0 as dividends and $667M as buybacks.

  • Average price paid for buybacks

    Buybacks ran $667M over the span, but the filings don't tag the share count needed to deduce the average price paid.

  • Net change in share count0.6%

    The diluted count barely moved (54M to 54M): buybacks roughly offset the stock issued to staff.

  • Dividend record

    No dividend line was reported in the filing data over the span; the record here neither confirms nor rules out a payout.

  • Return on what it retained54%

    Of the earnings it kept rather than paid out ($475M over the span), annual owner earnings (first three years vs last three) grew $256M, so each retained $1 added about 0.54 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.

Acquisitions & goodwill

from the balance sheet & the 10-year cash-flow record

Goodwill grows only when a company acquires and falls only when it concedes it overpaid. The size of that bet, the cash put into buying rather than building, and how much has already been written off.

$610M written down across 3 years (2018, 2020, 2021): goodwill the company has already conceded it overpaid for, charged against earnings. That is roughly 30% of the cash it put into acquisitions over the span. A write-down costs no cash (the cash went out when the deal was signed), but it is management marking its own past judgment to market.

Beside that spending sits $110M of cumulative amortization of acquired intangibles charged against earnings since fiscal 2015 — the purchase price of past deals, expensed over time.

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 yearChief executivePay, as filed“Actually paid”Owner earnings
2021Mr. Grzebinski$5.9M$6.9M$224M
2022Mr. Grzebinski$6.2M$6.8M$122M
2023Mr. Grzebinski$7.8M$9.3M$329M
2024Mr. Grzebinski$7.1M$9.4M$516M
2025Mr. Grzebinski$6.7M$7.1M$406M

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 ownership0.8%

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

  • CEO pay ratio66:1

    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$18M

    The slice of the business handed to employees in shares in fiscal 2025, 0.5% of revenue, equal to 3.5% 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 same industry, side by side on owner economics. Each column names the period it is read over, and a median resting on fewer than three years carries that count beside it; the group median at the foot is the line to read each figure against.

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 Kirby has delivered.

Kirby’s latest year runs above its own through-cycle margin — the reported figure may flatter a peak. So the tool opens on the through-cycle base, Graham’s averaging cutting both ways; clear the toggle below to read the latest year exactly as reported.

$

Through the cycle, Kirby earns about $343M on its 10.2% median owner-earnings margin. This year’s 12.1% margin runs above that; the reported figure may flatter a peak you'd be paying on. Normalize, below, values the price on that through-cycle figure rather than the latest year. It comes pre-checked here for that reason, the same rule that already normalizes a trough; clear it to price the year as filed.

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.
