Is Fonar Corp (FONR) a good stock to buy?
Nothing we have tested argues against it, and one check argues for it.
What each rating means, in numbers
Business quality — Strong. Passes 6 of the 7 health checks we can measure — things like making a profit, turning it into cash, and not piling on debt. Across 131,000 company-quarters the weakest scorers went on to fail at 5.4% against 1.4% for the strongest, in every era and all twelve sectors.
What "tested" means here, and why there is no score out of 100
Tested means the read was measured against what actually happened afterwards, on a history that keeps the companies that were later delisted, using only figures that had been filed on the day they are used. Survival was ranked on companies that really did fail. What an owner keeps was tested across the universe from 2011 to 2025.
The full record of everything we have tested is on the research pages.
Which benchmark. Over the period we tested, the median listed company returned +5.8% a year while the S&P 500 returned about +13.9% — the index is weighted by size and was carried by a handful of enormous winners. So "beats the index" and "beats the other companies you could have bought" are different questions. Where a read says it picks better companies, it means the second one. None of these gets you an index fund's return, and we would rather say that than imply otherwise.
The quality read is the strongest thing we have tested: 131,000 company-quarters across 5,300 companies, where the weakest scorers went on to fail at 5.4% against 1.4% for the strongest, holding in every era and all twelve sectors. It still says less likely to break, not likely to beat the market — every band in that study lost to the index at the median, because the median listed company does.
Each read is shown on its own rather than merged into a single score, so you can see which part is strong and which is weak instead of taking an average on trust.
▾ What goes into the smart-money reading
Contributions (weight × component score) sum to the total. This near-term score now includes fundamental health (leverage, FCF trend). It excludes the Altman Z score, whose retained-earnings input this filer does not report separately. See the Financial Health section for the full balance-sheet read.
Chance the S&P 500 falls 10% or more in the next three months.

📍 Where to start on this page, and what to look at first
How to read FONR
We are not publishing an intrinsic value for this one — the section below says exactly why. Everything on this page that comes straight from the filings and the tape is still here; treat the missing valuation as a known gap, not as a verdict on the business.
-
1
Reported earnings & margins ↓
What the company actually reported — unaffected by the valuation being held.
-
2
Balance sheet & book value ↓
Assets, liabilities and equity as filed.
-
3
Who's selling & betting against it ↓
Insider and short-interest behaviour needs no valuation model.
The share count we read for FONR looks wrong — common for multi-class / founder-controlled filers that report shares per share-class. That makes per-share figures (including intrinsic value) misleading, so we suppressed them. The company's total financials below are sound.
What to use instead: Lean on the totals — revenue, net income, cash flow — and the balance sheet. Multi-class share counts are being corrected; once fixed, the per-share valuation returns automatically.
This note is only about the single DCF fair-value number — FONR's full financial statements, health scores, and written analysis are all below.
Quality & solvency checks
Cheap stocks can be cheap for a reason. These screens warn when a low valuation comes paired with structural fragility.
What these health ratings mean, in numbers
Business quality — Strong. Passes 6 of the 7 health checks we can measure — things like making a profit, turning it into cash, and not piling on debt. Across 131,000 company-quarters the weakest scorers went on to fail at 5.4% within a year against 1.4% for the strongest, and that held in every era and all twelve sectors. It says "less likely to break", not "likely to beat the market".
Why it matters: Cheap-looking stocks (low P/E or P/B) often have low Z-scores because the market knows the company is dying. Z-score warns you before you fall into a value trap.
Reference: > 3.0 = safe zone · 1.81–3.0 = grey zone · < 1.81 = distress zone
Full explanation →
The Z-score needs working capital, retained earnings, EBIT, sales and total assets from the latest balance sheet, and at least one of those isn't reported in machine-readable form here — common for foreign private issuers. We leave it blank rather than compute a distress verdict from an estimated input. It doesn't affect the reported figures in the financial tables below.
▾ The checks — what passed, what didn't (and what we couldn't measure)
-
✓ Positive net incomeNet income $8.3M in FY2025.
-
✓ Positive operating cash flowOperating cash flow $11.3M (was $14.1M the prior year).
-
✓ Cash flow backs up reported profitOperating cash flow $11.3M vs net income $8.3M.
-
✗ Return on assets improvingReturn on assets 3.8% vs 4.9% a year ago.Why this matters: Is the company squeezing more profit out of each dollar of assets than last year? Rising = getting more efficient; falling = the opposite.
-
✓ Debt load (vs assets)Total debt is 0.0% of assets vs 0.1% a year ago ($0.0M of $216.9M assets).

✓ Short-term liquidity (current ratio)Current ratio 8.45x vs 7.86x a year ago.

Missing data is never counted as a pass or a fail — it's shown as n/a and excluded from the denominator. Each check compares the company against its own prior year.
A standard discounted cash flowDCF — Discounted Cash Flow — sums up all future cash a business will produce, adjusted for the fact that future dollars are worth less than dollars today.
Why it matters: It is the most fundamentally honest valuation method when applicable — but only works for companies with predictable, positive cash flow.
Reference: Best for: mature, profitable businesses. Fails for: pre-profit growth, banks, REITs.
Full explanation → (DCF) valuation is not meaningful for FONAR CORP due to the unreliability of per-share values, as indicated by missing or defaulted shares/market cap data. While the company is profitable and cash flow positive, investors are likely focused on its consistent revenue growth and operational health signals. The primary quantifiable risk is the illiquidity discount applied, suggesting difficulty in exiting positions.

Anatomy of a share
What you're buying per share. Bars are at the same scale so you can see the relative size of revenue, costs, cash flow, and debt — not just read them in a table.
What you actually need to decide
Every stock price is a disagreement. Here's the single thing that must go right for the bulls, the single thing that breaks the thesis, and the concrete signposts to watch so you can update your view as real results arrive.
- Continued positive net income in upcoming quarters
- Sustained operating cash flow generation
- Growth in revenue above the current 3.8%/yr rate
The trend, in plain numbers (FY2024 → FY2025, latest reported)
Straight from the financial statements — no model, no opinion. For a small or unprofitable company, the direction of these numbers usually tells you more than any single valuation.
- Revenue grew +1% to $104.4M.
- Free cash flow fell to $7.5M.
- Net income fell -21% to $8.3M.

Revenue Drivers
Why Is It Priced Like This?
Why Customers Pay
What we use instead: earnings (P/E, EV/EBIT), book value (P/B) — computed from the figures this company does report, shown in the sections below. Those numbers are unaffected by the missing cash-flow data.
The market is likely pricing FONAR based on its consistent profitability and positive operating cash flow, which has been positive for 5/5 years. Despite the challenges in a standard DCFDCF — Discounted Cash Flow — sums up all future cash a business will produce, adjusted for the fact that future dollars are worth less than dollars today.
Why it matters: It is the most fundamentally honest valuation method when applicable — but only works for companies with predictable, positive cash flow.
Reference: Best for: mature, profitable businesses. Fails for: pre-profit growth, banks, REITs.
Full explanation → valuation due to data limitations, the company's steady revenue growth of 3.8%/yr over four years suggests investor confidence in its established product and market position, rather than speculative future cash flows.
Business Model & Valuation
How They Make Money
The company has been profitable for 5/5 years and operating cash flow positive for 5/5 years, suggesting it funds itself through operations rather than relying on external equity raises.
Free Cash Flow DCF
This is the model the pipeline would normally apply to a company like this. Its output failed our checks here, so no intrinsic value is published; the notes below are context, not a valuation.
Show advanced inputs
| Revenue Growth | 3.8% |
| Eps Growth | 21.0% |
| Historical Fcf Growth | -16.7% |
| Sector Default | 10.0% |
| Best Estimate | 5.7% |
| Method | blend(70% revenue_cagr, 30% sector) |
| Growth Basis | total |
What this model does NOT do: this is a consolidated owner-earnings cash-flow model. Standalone segment assumptions: none. It does not project its revenue segments independently; their combined effect is embedded in the historical revenue and cash-flow trend the model extrapolates. The calculator above can only approximate a segment's impact through the single consolidated growth rate — it cannot model any one line separately. For a true segment-level view, build a separate model from the company's segment disclosures.

Market Signals
These are timing signals, not value signals — they describe the stock's recent price behavior, not what the business is worth. Use them for the "the thesis looks good, but is now the moment?" question. Each tile below explains what it's saying.
Why it matters: Short-term contrarian indicator. Extreme readings often precede mean reversion, though not always.
Reference: 30–70 normal · >70 overbought · <30 oversold
Full explanation → (14)78.7OverboughtBought up hard recently — stretched; pullbacks are common from here.
Why it matters: When the fast line crosses above the slow line, short-term momentum is turning up; below, turning down. A timing cue, not a value signal.
Reference: Line above signal = bullish momentum · below = bearish
Full explanation →BullishLine above signalThe fast trend is above the slow trend — short-term momentum is currently upward.
Technicals describe price, not the business. A great company can have a "bearish" tape (a buying chance) and a weak one a "bullish" tape (a trap). Pair these with the valuation and health sections above.

- Shares/market cap missing or defaulted; per-share valuation unreliable.
- Shares defaulted to 1; IV is NOT meaningful — treat as data-unavailable.
- DATA UNAVAILABLE: per-share values suppressed due to missing/unreliable shares data.
