The business in brief

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

What moves the needle
Gross margin has run about 18% and operating margin about 9.1% through the cycle, a thin spread that turns the result on volume and the cost of what it sells far more than on the price it sets. That margin has held in a narrow 7.7%–11% band over the years, so steadiness itself is the evidence — the lever is unit growth and cost discipline, not a moving line. Inventory runs near 13% of sales, so how fast it turns back into cash — and the risk of writing it down when demand softens — sits alongside the margin. Read this kind of business on the commodity price and the cost position. On its own account, the filing leans hardest on customer concentration, set against the numbers in what the filing emphasizes, below.
Is it a good business?
Return on capital has sat near the cost of capital (median 13%). By owner earnings: roughly 4% of revenue reaches owners as cash, consistently. This is price-taker territory, where the balance sheet and the cycle matter more than any multiple; the rest is in the 10-K.

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

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.

FY2021FY2025

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 $85M of owner earnings, the operating cash left after the $194M it takes just to hold its position. It put $154M more into growth; free cash flow, after that spending, was ($70M).

Owner-earnings marginowner earnings ÷ revenue3%6%7%4%4%

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 $194M, roughly its depreciation, the rate its assets wear out). The other $154M 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 $11M), owner earnings is nearer $73M.

Much of fiscal 2025's profit didn't arrive as operating cash; it sits in “working capital & other” above. That can be a real inventory or timing swing, or profit that doesn't run through operating cash at all: a heavy tax year, equity-method earnings, or investment income booked through investing. For a year like this, owner earnings understates the cash earned; the full cash-flow statement carries the rest.

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?

  • Adequate
    Operating income $286M ÷ interest expense $82M
    What this means

    Comfortable in a normal year, but below the margin of safety Graham looked for. Worth checking how stable the coverage has been across a full cycle.

  • How heavy is the debt, net of cash? $1.1B · 3.8× operating profit
    Meaningful net debt
    Cash $74M − debt $1.2B
    What this means

    Netting $74M of cash and short-term investments against $1.2B of debt leaves $1.1B owed, about 3.8× a year's operating profit (4.1× 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.

  • Long (60+ days)
    DSO 32 + DIO 62 − DPO 21 days
    What this means

    Days cash is tied up between paying suppliers and collecting from customers. Lower is better; a long cycle means growth itself eats cash.

Is it a good business?

  • Solid through the cycle
    5-yr median, range 8%–15%; 8% latest = NOPAT $211M ÷ invested capital $2.7B
    Industry peers: median 7%
    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 5 years (it ran 8% 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.

  • Thin through the cycle
    5-yr median margin, range 3%–7%; latest $85M = operating cash $278M − maintenance capex $194M
    Industry peers: median 7%
    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 3% of revenue this year, a 4% median across 5 years. It chose to put $154M more into growth, so free cash flow this year was ($70M) — the gap is investment, not weakness. Treating stock comp as the real expense it is (less $11M of SBC) leaves $73M.

  • Cash-backed
    Cash from ops $278M ÷ net income $157M
    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?

  • Not enough data
    What this means

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

  • Investing or harvesting? 1.80×
    Expanding
    Capex $348M ÷ depreciation $194M
    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.

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 Pass
    Revenue ≥ $2B · $3.1B
    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 Pass
    Current ratio ≥ 2× · 2.54×
    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 · $1.2B vs $583M 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 Pass
    A profit every year (5-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 Miss
    Uninterrupted dividends · none paid
    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.

  • 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 $3.18/share (latest year $2.77), the averaged base the calculator's gate runs on, and book value is $28.91/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, 2021–2025

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

  • Profitable years 5 of 5
    What this means

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

  • Return on capital ≥ 15% 0 of 4 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% → 10% (2-yr avg ends)

    In the filing’s words The filing claims pricing power in its strongest form — price raised, volume held — yet the margin here has not widened to match. The claim leads the record; weigh them together.

    What this means

    Through the cycle the operating margin widened — about 8% early to 10% lately, median 9% — pricing power intact or improving.

  • Reinvestment, incremental ROIC 9%
    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 +12%/yr
    What this means

    Owner earnings grew about 12% a year over the record.

  • Worst year 2022 · 7.7% op. margin
    What this means

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

  • Share count +0.1%/yr
    What this means

    Roughly flat share count, little dilution, little buyback.

Does AI threaten the moat?

Low contestability

The moat is physical, regulated or balance-sheet-funded, the kind AI cuts costs within but does not contest.

In its own filing Raised, but not as a competitor

The filing raises AI among its risks, but in other terms (security, regulation, energy or the like), not as a competitor to its product.

AI is unlikely to contest a moat that is physical, regulated or balance-sheet-funded; here it reads more as a cost tool than a threat.

From the company's latest filing.

How the cash was used, 2021–2025

Over the record, the business generated $1.3B of operating cash; how management split it reads as a reinvestor, most operating cash is plowed back into the business.

  • Reinvested$997M · 75%
  • Retained (debt / cash)$328M · 25%
  • Net change in share count0.3%

    The diluted count barely moved (57M to 57M): 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 retained4%

    Of the earnings it kept rather than paid out ($788M over the span), annual owner earnings (first three years vs last three) grew $33M, so each retained $1 added about 0.04 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 5-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.

Goodwill & intangibles$552M15% of all assets; the premium carried on the balance sheet for businesses acquired
Against book equity32%goodwill is this share of book equity; the rest is the company’s own retained and paid-in capital
Cash spent acquiring$978Mover 5 years buying other businesses, against $997M of capital spent building

None written down over the record; the goodwill is still carried at full cost. That is the deals holding their value on the books so far; whether they keep doing so is the test an owner watches, since the write-down, when it comes, is the admission the price was too high.

Goodwill, acquired intangibles and equity from the latest balance sheet; acquisition spend and write-downs summed across the 5-year record, from the company's own filings.

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
2023Brian R. Gray$5.0M$6.5M$211M
2024Brian R. Gray$6.9M$11.3M$185M
2025Brian R. Gray$5.8M−$242k$85M

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 ownership<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 ratio64:1

    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$11M

    The slice of the business handed to employees in shares this year, 0% of revenue, equal to 4% 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.

Inverting the record

Invert: instead of why Knife Riv Holding Co. is a good business, the question is what would make owning it a mistake, and whether those marks are in the record. Disconfirming tests across 2021–2025.

None of the 4 tests turned up a mark; each came back clean. A clean panel says only that these particular ways of being wrong are not written into the record.

Each test came back clean
  • Is it less profitable than it was?
  • Did the share count rise anyway?
  • Did reported profit become cash?
  • Are "one-time" charges a yearly habit?

Each test is read from the filings and is noisy alone; a flag can mark a cyclical trough or a year of heavy investment as easily as a problem. The filing says which.

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 Knife Riv Holding Co. has delivered.

Knife Riv Holding Co.’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, Knife Riv Holding Co. earns about $113M on its 3.6% median owner-earnings margin. This year’s 2.7% 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.
