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
- A metals and mining business, a price-taker on a global commodity.
- What moves the needle
- Operating margin has run about 3.8% through the cycle, a thin margin, where volume, cost discipline and the price it gets all bear on the result. That margin has held in a narrow 2.9%–6.1% 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 16% 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 9%). Owner earnings, the cash-based check, have been thin too. 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.

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 reported $273M of profit but $159M of owner earnings: $114M less than the profit line, taken out by capital spending and the timing of cash.

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 .
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?
- AdequateOperating income $515M ÷ interest expense $109M
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? $1.8B · 3.5× operating profitMeaningful net debtCash $120M − debt $1.9B
What this means
Netting $120M of cash and short-term investments against $1.9B of debt leaves $1.8B owed, about 3.5× a year's operating profit (3.8× 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?
- Solid through the cycle3-yr median, range 5%–12%; 12% latest = NOPAT $346M ÷ invested capital $2.8BIndustry peers: median 6%
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 3 years (it ran 12% 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 cycle4-yr median margin, range -2%–2%; latest $159M = operating cash $489M − maintenance capex $330MIndustry 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 2% of revenue this year, a 1% median across 4 years.
- Cash-backedCash from ops $489M ÷ net income $273M
In the filing’s words The filing leans on adjusted, non-GAAP earnings, but the GAAP profit is itself cash-backed — the adjustments are not papering over a cash shortfall here.
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 $115M ÷ Owner Earnings $159M — this fiscal year
What this means
Of $159M Owner Earnings, $115M (72%) went back to shareholders, $0 dividends, $115M buybacks. 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 72%; across the record (2022–2025) it is 103%, the capital-allocation section below.
- Investing or harvesting? 1.00×MaintainingCapex $330M ÷ depreciation & amortization as filed $330M
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? 0.2%The count is edging downStock compensation $19M (fiscal 2025), 0.2% of revenue · repurchases $115M · diluted shares -3.4% 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 · 1 of 3 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 · $8.4B
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 MissCurrent ratio ≥ 2× · 1.29×
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 · $1.9B vs $524M 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.
- 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 $1.18/share (latest year $2.01), the averaged base the calculator's gate runs on, and book value is $7.02/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, 2022–2025
Whether the record’s returns held, and what the capital reinvested earned.
- Profitable years 4 of 4
What this means
Never lost money over the record, the earnings stability Graham insisted on.
- Return on capital ≥ 15% 0 of 3 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 4% → 5% (2-yr avg ends)
What this means
Through the cycle the operating margin widened — about 4% early to 5% lately, median 3% — 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 −31%/yr
What this means
Owner earnings shrank about 31% a year over the record.
- Worst year 2022 · 2.9% op. margin
What this means
Stayed profitable even in its hardest year, the resilience that survives recessions.
- Share count −1.2%/yr
What this means
The share count is shrinking, buybacks are quietly growing your slice of the business.

Debt maturity

Bars scaled to the largest single year; “later” is everything due after 2030, shown apart since it dwarfs the years.
Against what the business has and earns
Cash on hand as of Jun 30, 2026 plus a year’s owner earnings comes to $322M against the $5M due in the twelve months after the Dec 31, 2025 schedule: 64 times it.
Maturity schedule extracted from the company’s Dec 31, 2025 annual report and reconciled to the total the table states.
How the cash was used, 2022–2025
Over the record, the business generated $1.6B of operating cash; how management split it reads as a reinvestor, most operating cash is plowed back into the business.
- Reinvested$1.4B · 88%
- Buybacks$194M · 12%
- Returned to owners$194M
103% of the owner earnings the business produced over the span, $0 as dividends and $194M as buybacks.
- Average price paid for buybacks—
Buybacks ran $194M over the span, but the filings don't tag the share count needed to deduce the average price paid.
- Net change in share count−4.6%
The diluted count fell from 147M to 140M, so the buybacks outran 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 retained5%
Of the earnings it kept rather than paid out ($595M over the span), annual owner earnings (first three years vs last three) grew $28M, so each retained $1 added about 0.05 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.
Management, ownership & pay

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.
