CRMD, CorMedix Inc.
CorMedix Inc. is a biopharmaceutical company focused on developing and commercializing therapeutic products for life-threatening diseases and conditions.
According to the 2025 United States Renal Disease System, reporting data from 2023, there were approximately 485,000 End-Stage-Renal-Disease ("ESRD") patients on permanent hemodialysis in the U.S. and over 25% of these utilized a CVC for vascular access.
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 DefenCath (83%), Melinta Portfolio (15%) and Contract revenue (2%).
- What moves the needle
- Operating margin has reached 48% at its best but run negative through the cycle (median −9997%) on a 14% gross margin — so the question is which reading is truer: whether the median was pulled below zero by one-off charges, by the cycle, or by spending it is still growing into, and whether it settles back at a profit. Stock-based pay runs about 596% of sales, a real and recurring claim on owners that the GAAP margin understates. Read this kind of business on the pipeline against the patent cliff, and pricing. 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 rarely cleared the cost of capital (median −202%, above 15% in 1 of 8 years). 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.

Owner earnings vs. net income
Owner earningsNet incomeThe accountant's number, and the cash an owner can take; the gap is the tell.
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 $174M of owner earnings, the operating cash left after the $677K it takes just to hold its position. It put $2M more into growth; free cash flow, after that spending, was $173M.
| FY2025 | FY2024 | FY2022 | FY2021 | FY2020 | |

| Owner-earnings marginowner earnings ÷ revenue | 56% | -117% | -37368% | -11112% | -9230% |
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 $677K, roughly its depreciation, the rate its assets wear out). The other $2M 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 $14M), owner earnings is nearer $161M.
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?
- Can it pay its interest? 54.0×ComfortableOperating income $150M ÷ interest expense $3M
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.
- Net cashCash $145M + ST investments $4M − debt $6M
What this means
Cash and short-term investments exceed every dollar of debt by $142M, on net the company owes nothing, and can act from strength when others can't. 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 201 + DIO 491 − DPO 130 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?
- Below average through the cycle8-yr median, range -928%–58%; 56% latest = NOPAT $150M ÷ invested capital $267MIndustry peers: median -62%
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 8 years (it ran 56% 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.
- Positive this year, negative across the cyclelatest $174M = operating cash $175M − maintenance capex $677K (positive this year), after an earlier loss stretch (10-yr median -8692%)Industry peers: median -34%
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 56% of revenue this year, a -8692% median across 10 years. Treating stock comp as the real expense it is (less $14M of SBC) leaves $161M.
- Cash-backedCash from ops $175M ÷ net income $163M
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? 3.34×ExpandingCapex $2M ÷ depreciation $677K
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 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 MissRevenue ≥ $2B · $312M
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× · 2.11×
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 · $6M vs $193M 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 MissA profit every year (10-yr record) · 9 loss years
What this means
Graham wanted earnings in each of the past ten years, the stability a defensive owner leans on.
- Dividend record MissUninterrupted 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.
- Earnings growth —Earnings +33% over the record · —
What this means
Earnings were negative early in the record, a growth rate isn't meaningful.
- 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 $0.49/share (latest year $2.08), the averaged base the calculator's gate runs on, and book value is $5.17/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, 2015–2025
Whether the record’s returns held, and what the capital reinvested earned.
- Profitable years 1 of 10
What this means
Lost money in 9 year(s), look at what happened there before trusting the average.
- Operating margin −9657% → −15608% (3-yr avg ends)
In the filing’s words The filing attributes gains to higher prices, but the margin in the record has not followed — the claim outruns the result here.
What this means
The recent-years average (−15608%) sits below the early years (−9657%), but the latest year (48%) is back near the early level: a cyclical trough dragging the window down, not a one-way slide. The through-cycle median is −9997% — read it across the cycle, not on the dip.
- 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.
- Worst year 2022 · −46819.9% op. margin
What this means
Operations went underwater in 2022, understand why before trusting the good years.
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 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.

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 | Pay, as filed | “Actually paid” | Net income |
|---|---|---|---|
| 2023 | $2.5M | $1.9M | — |
| 2024 | $2.4M | $5.4M | ($18M) |
| 2025 | $6.1M | $8.9M | $163M |
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. Net income is the whole business's, as filed, for the same fiscal years.
- Insider ownership3.5%
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$14M
The slice of the business handed to employees in shares this year, 4% of revenue, equal to 9% 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.
