The business
What it sells, where the money comes from, the kind of company it is.
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 led by North America On-Highway (51%) and Service Parts Support Equipment and Other (21%), with 3 more lines behind.
- What moves the needle
- Gross margin has run about 48% and operating margin about 29% through the cycle, a solid spread between what it charges and what the product costs to make. That margin has stayed fairly steady relative to where it runs (25%–34% over the years), so unit growth and cost discipline, not a moving line, are the lever. Read this kind of business on volume, mix and the cost of the platform. 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 run high across the record (median 21%, above 15% in 8 of 10 years). Owner earnings agree: roughly 23% of revenue reaches owners as cash, consistently. Whether these returns reflect real pricing power or an accounting artifact is the judgment the 10-K is for.
Every line is arithmetic on the company's filings, shown in full in the sections below.

- Outside North America On-Highway+2.8%
“Outside North America On-Highway end market net sales were up 3% for the year ended December 31, 2025 compared to the year ended December 31, 2024, principally driven by higher demand in Europe and South America and price increases on certain products, partially offset by lower demand in Asia.”

Owner earnings vs. net income
Owner earningsNet incomeThe accountant's number, and the cash an owner can take; the gap is the tell.
Where the cash went
ReinvestBuybacksDividendsAcquisitionsRetainedBeyond op. cashEach 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.
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 $719M of owner earnings, the operating cash left after the $117M it takes just to hold its position. It put $58M more into growth; free cash flow, after that spending, was $661M.

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 $117M, roughly its depreciation, the rate its assets wear out). The other $58M 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 $27M), owner earnings is nearer $692M.
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
Will it survive?
- Interest expense not tagged in the data
What this means
No usable interest-expense line was tagged in the filing data, but the balance sheet carries real net debt — so the interest burden here is unknown, not absent. Read the debt on the net-debt check below.
- How heavy is the debt, net of cash? $1.4B · 1.6× operating profitModest net debtCash $1.5B − debt $2.9B
What this means
Netting $1.5B of cash and short-term investments against $2.9B of debt leaves $1.4B owed, about 1.6× a year's operating profit (3.3× on the gross debt, before the cash). It also holds $24M in longer-dated marketable securities; counting those, it sits at $1.4B of net debt. 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 40 + DIO 75 − DPO 45 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?
- High through the cycle10-yr median, range 9%–25%; 21% latest = NOPAT $682M ÷ invested capital $3.3BIndustry peers: median 12%
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 21% 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.
- High through the cycle10-yr median margin, range 20%–28%; latest $719M = operating cash $836M − maintenance capex $117MIndustry peers: median 5%
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 24% of revenue this year, a 22% median across 10 years. Treating stock comp as the real expense it is (less $27M of SBC) leaves $692M.
- Cash-backedCash from ops $836M ÷ net income $623M
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 halfDividends + buybacks $419M ÷ Owner Earnings $719M
What this means
Of $719M Owner Earnings, $419M (58%) went back to shareholders, $91M dividends, $328M buybacks. Net of $27M stock comp, the real buyback was about $301M. 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.
- Investing or harvesting? 1.50×ExpandingCapex $175M ÷ depreciation $117M
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 · 5 of 6 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 PassRevenue ≥ $2B · $3.0B
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 PassCurrent ratio ≥ 2× · 4.85×
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 MissDebt ≤ working capital · $2.9B vs $1.8B 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 PassA 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 PassUninterrupted 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 PassEarnings +33% over the record · +49%
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 $8.15/share (latest year $7.51), the averaged base the calculator's gate runs on, and book value is $22.51/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% 8 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 29% → 30% (3-yr avg ends)
In the filing’s words The filing ties gains to its own pricing, but names price competition too — pricing power that is real yet contested, not unopposed. The margin shows who is winning.
What this means
Through the cycle the operating margin held roughly steady — about 29% early, 30% lately, median 29%.
- 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 +3%/yr
What this means
Owner earnings grew about 3% a year over the record.
- Worst year 2016 · 24.6% op. margin
What this means
Stayed profitable even in its hardest year, the resilience that survives recessions.
- Dividend record paid
What this means
Paid a dividend in 10 of the years on record.
Does AI threaten the moat?
Low contestabilityThe moat is physical, regulated or balance-sheet-funded, the kind AI cuts costs within but does not contest.
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, 2016–2025
Over the record, the business generated $7.2B of operating cash; how management split it reads as a cash returner, paying most of what it earns straight back to owners.
- Reinvested$1.3B · 19%
- Dividends$842M · 12%
- Buybacks$4.0B · 56%
- Retained (debt / cash)$1.0B · 14%
- Returned to owners$4.8B
78% of the owner earnings the business produced over the span, $842M as dividends and $4.0B as buybacks.
- Source of fundingOperating cash
Operating cash covered reinvestment and returns; over the span debt rose $2.1B and cash and short-term investments rose $106M.
- Average price paid for buybacks—
Buybacks ran $4.0B over the span, but the filings don't tag the share count needed to deduce the average price paid.
- Net change in share count−50.3%
The diluted count fell from 169M to 84M, so the buybacks outran the stock issued to staff.
- Dividend record$1.07/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—
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.
Acquisitions & goodwill
from the balance sheet & the 10-year cash-flow recordGoodwill 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.
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 10-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 year | Chief executive | Pay, as filed | “Actually paid” | Owner earnings |
|---|---|---|---|---|
| 2021 | Mr. Graziosi | $8.5M | $5.1M | $531M |
| 2022 | Mr. Graziosi | $9.2M | $12.0M | $548M |
| 2023 | Mr. Graziosi | $10.3M | $18.8M | $659M |
| 2024 | Mr. Graziosi | $12.3M | $40.3M | $690M |
| 2025 | Mr. Graziosi | $8.0M | −$424k | $719M |
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.
- Stock-based compensation$27M
The slice of the business handed to employees in shares this year, 1% of revenue, equal to 3% 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 Allison Transmission Holdings Inc. 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 2016–2025.
4 of the 6 tests turned up something to look into; the other 2 came back clean.
- Look hereIs it less profitable than it was?22.3% vs 27.1%
The owner-earnings margin averaged 27.1% early in the record and 22.3% across the last three years, and the latest year has not recovered. Ask the filing whether that is a structural drift or a cyclical trough — price, mix, cost, or a competitor — and whether it is permanent.
- Look hereDid debt outgrow the business?$2.2B → $4.3B
Debt rose from $2.2B to $4.3B while owner earnings went from about $616M to $689M — about 3.5 years of owner earnings in debt then, about 6.2 now: measured against what the business earns, the balance sheet carries more debt than it did. Debt raised for buybacks or deals rather than growth is the kind that bites in a downturn.
- Look hereDid receivables and inventory outpace sales?18% → 47% of sales
Receivables and inventory grew from $323M to $1.7B while revenue grew 98%: working capital is climbing faster than sales (18% of revenue then, 47% now). That can mean customers paying slower, stock building up, or revenue pulled forward. The filing's cash-flow and receivables notes say which.
- Look hereAre "one-time" charges a yearly habit?5 of 10 years
Management took an impairment or write-down in 5 of the last 10 years, $68M in all. Taken across the majority of the record, the "one-time" label is wearing thin — ask whether these are past deals coming due rather than genuinely isolated events. Read it beside the goodwill the company still carries.
- Did the share count rise anyway?
- Did reported profit become cash?
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.

Free cash flow $609M on 83M shares outstanding, per the 10-Q cover, as of 2026-04-23; net debt $4.0B. The base is the latest year by default; Normalize values it on the through-cycle median owner-earnings margin (to avoid paying on a peak year). Net of stock comp treats option pay as the expense it is. Capex ($202M) runs well above depreciation ($146M), so this is a build-out; Steady-state swaps total capex for maintenance (≈ depreciation), lifting the base to about $694M, the cash it would throw off if it stopped expanding.
