How to read APM (speculative micro-cap)
No model can pin a precise fair value on a company this small — but that does not mean there is nothing to learn. The useful questions are what the price is betting on, and whether the company can survive long enough to deliver it.
-
1
Reverse-DCF — what growth the price assumes ↓
The single most useful number here: it backs out the growth the market is paying for. If that figure is "historically unprecedented," the price is running on hype, not fundamentals.
-
2
Cash runway ↓
A pre-profit micro-cap lives or dies on whether it can fund itself to profitability before running out of money and diluting you.
-
3
The raw financial statements + the 10-K ↓
At this scale, the actual numbers, insider ownership, and share-count trend tell you more than any ratio.
Standard DCF doesn't fit APM well — but that's expected for this kind of business. The Rule of 40 (Pre-Profit Growth) Lens below uses the metrics actually used by analysts who value measuring & controlling devices. Reverse DCF + Football Field also work as cross-checks.
How to read a company this small
This is a clinical-stage biotech with little or no revenue. Standard DCF requires future cash flows to discount — there's nothing to discount yet. The value is entirely in the drug pipeline and the probability that it works.
- Drug pipeline — phase of each candidate (Phase I → II → III → FDA approval); each phase has historical success probabilities
- Total Addressable Market (TAM) of the lead indication — bigger market = bigger payoff if approved
- Cash runway — months of cash left at current burn rate before they need to raise more (and dilute shareholders)
- Strategic partnerships — Big Pharma collaborations validate the science and bring milestone payments
- Patent / exclusivity timeline — how long until generics if approved
- Insider holdings + management track record — biotech execs with prior wins are a real signal
P/E, P/B, EV/Sales, ROE — meaningless when there's no revenue or earnings. DCF outputs are nonsense.

How does APM stack up against its closest peers?
Ideally we compare APM only to same-industry peers, but too few exist in our universe right now, so the basket below mixes in broader-sector names. Treat the multiples as rough context, not a valuation. For a leveraged business, EV/EBIT and FCF yield (both in the table) are usually more reliable than EV/Sales, because revenue multiples ignore differences in margins and debt.
▾ What's "EV / Sales" in plain English?
EV (Enterprise Value) = market cap + total debt − cash. It's "what you'd pay to buy the entire company outright" — you pay the market cap to shareholders and take over their debt, but you keep their cash. EV is fairer than market cap alone because it includes the debt the new owner inherits.
EV / Sales = EV ÷ annual revenue. So "2.5×" means investors pay $2.50 of enterprise value per $1 of yearly sales. Higher = market is paying more per dollar of sales (usually because they expect future growth or fat margins).
p25 / median / p75 are the 25th, 50th (middle), and 75th percentile of the peers' multiples. Half the peers fall between p25 and p75. The median (p50) is the typical peer — that's the benchmark we compare to.
| EV / SalesEV / Sales — For every $1 of yearly revenue, this is how many dollars investors pay to own the whole business (including debt). Why it matters: Works for pre-profit growth companies where P/E and FCF don't apply. The most apples-to-apples cross-company multiple because it ignores accounting choices. Reference: 1–3x for mature companies · 4–10x for software/SaaS · 10–20x for hypergrowth · >20x is rare and demanding Full explanation → |
1.0x / 1.5x / 2.6x |
| EV / Gross ProfitEV / Gross Profit — Enterprise value divided by gross profit — the multiple paid for what each dollar of sales contributes after direct costs. Why it matters: More refined than EV/Sales for high-margin businesses (software, marketplaces) where gross margin is the real economic engine. Reference: 8–15x for SaaS · 15–25x for hypergrowth software · >30x demanding Full explanation → |
3.0x / 3.3x / 6.1x |
Bold middle number = median peer. Half the peers trade above it, half below. Computed over 8 peers (broad — see caveat); implausible multiples excluded.
⚠️ Important caveat: peer multiples only work if the peers are genuinely comparable. Always check the peer list below — if the auto-picker grabbed micro-caps or unrelated businesses, the comparison is noise. A medical-device giant priced against tiny biotech startups won't produce a useful signal.

Quality & solvency checks
Cheap stocks can be cheap for a reason. These screens warn when a low valuation comes paired with structural fragility.
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 -$1.4M in FY2025.Why this matters: Does the company actually earn a profit? Sustained losses eventually force it to raise money — diluting you — or take on debt.
-
✗ Positive operating cash flowOperating cash flow -$1.8M (was -$1.2M the prior year).Why this matters: Profit can be an accounting figure; cash from running the business is harder to fake. Negative operating cash flow means the core business consumes cash and must be funded externally.
-
✗ Cash flow backs up reported profitOperating cash flow -$1.8M vs net income -$1.4M.Why this matters: When cash generated exceeds reported earnings, profits are high-quality (not propped up by accruals or one-time items).
-
✓ Return on assets improvingReturn on assets -7.3% vs -26.5% a year ago.
-
✓ Debt load (vs assets)The filing reports no interest-bearing debt in either year (total assets $18.7M).
-
✓ Short-term liquidity (current ratio)Current ratio 0.78x vs 0.22x a year ago — improved, but still below 1.0: the ✓ grades the trend, the level remains a caution flag.
-
✗ Share count (dilution)Share count rose 34.8% (5.5M → 7.4M year-over-year).Why this matters: Issuing lots of new shares splits the pie into more pieces, shrinking your slice. Stable or falling share count protects existing owners.
-
· Pricing power (gross margin) (n/a — data not reported; not scored)
-
· Sales per asset (asset turnover) (n/a — data not reported; not scored)
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.
Plain English: the company holds about $3M in cash and is burning roughly $2M/year in operations. At that pace, the cash lasts 23 mo before it must raise capital (diluting shareholders), take on debt, or cut spending.
Assumes constant burn and ignores financing/asset sales. For pre-profit biotech and growth companies, this matters more than a DCF — a great drug pipeline is worthless if they run out of money before approval.
What if you assume different inputs?
Here's where we land — and what happens if you change the assumptions. Drag the sliders to set your own Discount RateDiscount Rate — The annual return you demand for taking single-stock risk instead of buying a safe Treasury or index fund.
Why it matters: Higher discount rate = stricter valuation (a stock has to produce more cash to be worth holding). Lower = more generous.
Reference: 8–12% is standard · 9–10% matches S&P 500 historical return · Below 7% is illogical for single-stock risk

Note: no headline intrinsic value is published for this stock (the valuation is held for a data-quality reason — see the notes above). The calculator below is a what-if tool: the values it produces are your assumptions played out, not our estimate.
A full intrinsic value isn't shown for APM because the valuation is currently held for a data-quality reason (see the guardrail notes above). The reverse-DCF reading still works — it needs only the price and cash flow — but we won't publish a forward value until the underlying data passes our checks.

⚙ Advanced — tinker with every input (beta, growth, rate path, margin → full intrinsic value)
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 Aptorum Group Ltd because the company has negative net income and operating cash flow, indicating it is not currently profitable. Valuing it would require projecting a clear path to profitability and positive free cash flowFree Cash Flow (FCF) — Operating cash flow minus capital spending: cash left after a company covers operating costs, taxes and interest and reinvests in the business — but BEFORE repaying debt principal or paying dividends. The cash actually available to investors.
Why it matters: A company can show big profits on paper while burning through cash. FCF is what actually fills the bank account.
Reference: Healthy mature businesses convert 8–15% of revenue into FCF · Growth companies often negative
Full explanation →, which is highly speculative at this stage. Investors are likely betting on the potential success of its drug pipeline, which is not captured in backward-looking cash flow models. The primary quantifiable risk is its current ratio of 0.78, indicating current liabilities exceed liquid assets.

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's free cash flow / what do these mean?
Revenue per share — how much the business earns from customers, divided by the number of shares outstanding. Top of the income statement.
Earnings per share — profit left after operating costs, interest, and taxes, per share. Two versions appear on this page and are not interchangeable: GAAP diluted EPS uses the company's weighted-average diluted share count during the reporting period (this is the "earnings" in "price-to-earnings"); net income per current share divides annual net income by today's share count. They differ whenever the share count has changed.
Owner-earnings free cash flow per share — the cash the business produces for shareholders. Savng's owner-earnings FCF subtracts capital expenditures and stock-based compensation from operating cash flow (SBC is a real dilution cost even though it's non-cash). This is deliberately more conservative than "standard" FCF, which subtracts only capital expenditures — so our figure is lower than the headline FCF you'll see elsewhere. FCF funds dividends, buybacks, debt repayment, and acquisitions; a company can report positive earnings yet negative FCF.
Debt per share — total interest-bearing borrowings divided by shares. High debt-per-share next to thin FCF-per-share is a fragility signal.
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.
- Announcement of positive Phase 2/3 clinical trial results
- Regulatory approval for a key drug candidate
- Securing significant licensing or collaboration agreements
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.
- Still unprofitable at -$1.4M — loss narrowing.
- Free cash flow is negative at -$1.8M — the cash burn widened vs last year.

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 pricing Aptorum Group based on the potential future value of its drug pipeline rather than current cash flows, as evidenced by its negative net income and operating cash flow. The market may be assigning value to the potential success of its clinical-stage drug candidates, which is not in the model. This speculative valuation reflects expectations for future revenue generation from successful product development and commercialization, rather than current profitability.
Business Model & Valuation
How They Make Money
The company funds itself through equity raises, as indicated by its negative operating cash flow and lack of dividends or buybacks.
Growth / Revenue DCF
Negative free cash flow: revenue/margin growth model used - standard FCF DCF is unreliable for companies still scaling.

What this model does NOT do: this is a consolidated owner-earnings FCF 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.
Maturity & Competitive Position
Moat Signals
Net income and operating cash flow have been negative in the latest period, with no profitability in the last five years.

Cash Flow (5yr)
Capital expenditure isn't tagged in this filer's machine-readable data (the CapEx column shows "—"). The free-cash-flow column is therefore operating cash flow less stock-based compensation only — an upper bound on true owner earnings, not the real figure. Companies that report capex under a custom label (some large IFRS filers do) look better here than they are.
| Year | Operating CF | CapEx | − SBC & adj. | Free Cash Flow |
|---|---|---|---|---|
| 2025 | -1.8M | — | — | -1.8M |
| 2024 | -1.2M | — | — | -1.2M |
| 2023 | -7.7M | 3,015 | 1.3M | -9.0M |

| 2021 | -14.7M | 131,750 | 1.7M | -16.5M |
How we define FCF: operating cash flow − capital expenditure − stock-based compensation (owner-earnings basis — SBC is a real cost to shareholders even though it's non-cash). This is the same owner-earnings FCF definition the valuation model uses, though the DCF's starting value is a projected from revenue × terminal margin, not this single year.
