CDNL, Cardinal Infrastructure Group Inc.
A capital-intensive business, run on heavy physical assets that must be kept working and earn a return above what they cost to maintain.
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 moves the needle
- Operating margin has run about 11% through the cycle, a solid margin the cost base and competition set as much as the price does. That margin has held in a narrow 8.9%–12% band over the years, so steadiness itself is the evidence — the lever is unit growth and cost discipline, not a moving line. On its own account, the filing leans hardest on debt terms & refinancing, set against the numbers in what the filing emphasizes, below.
Every line is arithmetic on the company's filings, shown in full in the sections below.

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 $13M of owner earnings, the operating cash left after the $25M it takes just to hold its position. It put $19M more into growth; free cash flow, after that spending, was ($6M).

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 $25M, roughly its depreciation, the rate its assets wear out). The other $19M 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 $6M), owner earnings is nearer $7M.
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
“Changes in Internal Control Over Financial Reporting We have identified material weaknesses in the Company's internal controls over financial reporting.”
The figures below are only as sound as the controls that produced them. read the note →
Will it survive?
- ComfortableOperating income $40M ÷ interest expense $7M
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? $121M · 3.0× operating profitMeaningful net debtCash $0 − debt $121M
What this means
Netting $0 of cash and short-term investments against $121M of debt leaves $121M owed, about 3.0× a year's operating profit. 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?
- SolidNOPAT $37M ÷ invested capital $261M (debt + equity − cash)Industry peers: median 9%
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. Asset-light businesses (R&D expensed, little capital) read artificially high, pair this with Owner Earnings.
- Solid through the cycle3-yr median margin, range 3%–8%; latest $13M = operating cash $38M − maintenance capex $25MIndustry peers: median 4%
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 7% median across 3 years. It chose to put $19M more into growth, so free cash flow this year was ($6M) — the gap is investment, not weakness. Treating stock comp as the real expense it is (less $6M of SBC) leaves $7M.
- Cash-backedCash from ops $38M ÷ net income $23M
In the filing’s words The filing discloses a material weakness in its financial controls — the reported numbers here, and the record built on them, are only as reliable as the controls that produced them.
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? 1.74×ExpandingCapex $44M ÷ depreciation $25M
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 · 2 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 MissRevenue ≥ $2B · $456M
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× · 2.35×
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 PassDebt ≤ working capital · $121M vs $124M 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 $1.43/share (latest year $1.50), the averaged base the calculator's gate runs on, and book value is $9.24/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.
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.
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.

Acquisitions & goodwill
from the balance sheet & the 3-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.

Management, ownership & pay
read the proxy →From the proxy: how much of the business the people running it own, and how they are paid.
- Insider ownership61.7%
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$6M
The slice of the business handed to employees in shares this year, 1% of revenue, equal to 15% 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.
