Our tested checks disagree with each other, so the answer depends on something further down the page rather than on any one measure.

What each rating means, in numbers

Business quality — Middling. Passes 4 of the 8 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.

How wild is the price? — Average. The share price swings about 39% in a typical year, which puts it in the middling. Out of every 100 companies that swung like this, about 1.5 went bankrupt within the year. Across the three periods we tested that ran from 0.2% to 3.0%.

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.

How to read BNTX (pre-profit growth)

BNTX generates real cash flow, but the DCF here is a low-confidence estimate — the value is sensitive to how we normalize cash flow, cyclicality, and secular/industry risk. Treat the DCF as one input, then pressure-test it against the reverse-DCF, leverage, and the operating trends below.

ⓘ Why does BNTX trade at $96.96?

BioNTech SE has 241.7 million shares outstanding. At $96.96 per share, the market values all outstanding BNTX equity at $23.4 billion. That's market capitalization, not enterprise value — enterprise value also accounts for debt and cash (BNTX carries little or no debt, so the two are close here). The share price by itself tells you almost nothing — a company can pick any share price by splitting or issuing more shares. What matters is the total value (Market Cap?Market Cap — The total dollar value the market is assigning to the entire company.
Why it matters: This is the number that actually matters when comparing companies. Two companies with the same business but different share counts have the same market cap.

What growth must the market believe? ?Reverse DCF — Instead of asking "what is this stock worth?", asks "what growth rate is the current market price already assuming?"
Why it matters: It crystallizes the bull thesis as a single number you can argue with. If the market expects 40% growth for 10 years and you do not believe that, the stock is overvalued.
Reference: 10–15% = sustainable for strong companies · 20–25% = exceptional · 30%+ = historically very rare

Traditional DCF asks "what is this stock worth?" Reverse DCF flips it: it treats today's price as correct and solves for the growth rate that justifies it. In plain terms — if our model is right about everything else, the company's cash flow would have to grow (or shrink) by this much every year for the next 5 years for today's price to make sense. If that required growth looks unrealistic, the price is stretched; if it looks easy to beat, the price may be cheap.

To justify today's $96.96 price, BNTX's free cash flow?Free 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.

A 5-year cash-flow growth rate, fading to terminal growth afterwards, implied by today's live price.
▾ Exactly how this 5-year figure is computed
Starting FCF/share: $2.21 (projected from revenue × terminal margin)
Forecast length: 5 years at the solved rate, then a linear fade to terminal growth over years 6-10 — the same shape the DCF above uses
Terminal growth after the fade: 1.6%
Discount rate: 9.5% (the rate the model used)
Price used: $96.96 — the live price shown on this page (not frozen)
Method: solve for the constant annual growth rate that makes the discounted 10-year FCF stream + terminal value equal today's price.
Exceptional

Sustaining 22-30% a year for five years is rare, and rarer still at large scale where the base is already enormous. The price is betting on a top-tier outcome.

For reference: Exceptional is not a compliment here — sustaining mid-teens cash-flow growth for ten straight years is rare at scale. The price is betting on a top-tier outcome.

How does BNTX stack up against its closest peers?

We take the 8 same- or closely-related-industry companies closest in size to BNTX and check what investors are paying for each dollar of their revenue (or profits). If BNTX is much more expensive on the same yardstick, that's a red flag — unless you have a specific reason it deserves a premium. 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.

What peers trade at (p25 / median / p75)
EV / Sales?EV / 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.

Peer-implied value check
We're not showing a peer-implied price for BNTX: its closest comparables are valued very differently from one another (from 5.3× to 23.4× sales across the middle half), so any single "peer value" would mostly reflect which companies happened to be picked. Read the table as context.

⚠️ 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.

What these health ratings mean, in numbers

Business quality — Middling. Passes 4 of the 8 health checks we can measure — making a profit, turning it into cash, not piling on debt, not issuing shares. 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".

Bankruptcy score (Altman Z) — Very safe. Altman Z is 6.16. It combines working capital, retained earnings, operating profit and market value against total assets into one bankruptcy score. Above 3.0 is the safe zone, 1.8 to 3.0 is grey, below 1.8 is the distress zone. It was calibrated on manufacturers in 1968, so it reads asset-light and heavily-financed businesses badly — which is why it is one input here and never the verdict.

The workings
Altman Z-Score?Altman Z-Score — A bankruptcy-risk score combining 5 financial ratios into one number. Predictive of bankruptcy within 2 years.
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.

Full explanation →
6.16
Safe zone

Safe zone under the classic Altman thresholds — companies scoring here have historically gone bankrupt only rarely within ~2 years. A screening signal, not a guarantee.

The classic Z-score was calibrated on manufacturers. It is less reliable for asset-light or non-manufacturing businesses (broadcasters, media, software, services) and not applicable to banks, REITs, or insurers — for those the coefficients and the asset-turnover term distort the result. Read it as one screening input, not a verdict.

4 passed · 4 failed · 1 n/a
Partial result, not a standard F-score: 4 of 8 measurable checks passed. 1 of the 9 standard checks couldn't be measured, so this is scored out of 8, not 9 — it isn't comparable to a published F-score.
▾ The checks — what passed, what didn't (and what we couldn't measure)
  • ✗ Positive net income
    Net income -$1,283.4M 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 flow
    Operating cash flow $515.1M (was $224.8M the prior year).
  • ✓ Cash flow backs up reported profit
    Operating cash flow $515.1M vs net income -$1,283.4M.
  • ✗ Return on assets improving
    Return on assets -5.0% vs -3.1% 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)
    The filing reports no interest-bearing debt in either year (total assets $25,836.6M).
  • ✓ Short-term liquidity (current ratio)
    Current ratio 7.54x vs 7.45x a year ago.
  • ✗ Share count (dilution)
    Share count rose 0.5% (240.4M → 241.7M 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)
    Asset turnover 0.13x vs 0.13x a year ago.
    Why this matters: Asset turnover measures how much revenue each dollar of assets generates. Rising = more productive use of the asset base.

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.

Where the discount rate comes from — discount rate = risk-free + beta × equity-risk-premium
What you'd earn risk-free from government bonds — the floor under every other rate. Slide it down to model the market expecting rate cuts (value rises); up for higher-for-longer.
The extra yearly return investors demand for owning stocks instead of safe bonds — the price of risk. History runs ~4.5–6.5%; we default to 5.5% (slightly conservative). It's an estimate, not a law — lower it if you think equities are less risky than that.
Inflation reduces the purchasing power of a nominal return: a 9% gain at 3% inflation is about 6% in real terms. The intrinsic value above is already in today's dollars (a nominal DCF carries inflation in both the growth and the discount rate), so this switch does not change the value — it restates the return in real terms.
Higher beta → higher discount rate (sets the rate above). 1.0 = moves with the market.

    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.

    BNTX BioNTech SE stock anatomy showing per-share revenue, operating expenses, free cash flow, and debt
    −39.6%
    loss
    Where each $1 of revenue goes
    For every $1 of revenue, BNTX currently loses 39.6¢ — costs exceed sales. A money-losing business can still be a good investment if losses are shrinking toward profitability; check the trend, not just the snapshot.
    Net margin = net income ÷ revenue (most recent fiscal year).
    Plain English: each share (at $97) represents $13.41 of revenue per share per year, $5.31 lost per share per year, and $0.82 of owner-earnings free cash flow per current share (latest fiscal year) from the latest fiscal year. The filing reports no interest-bearing debt — the 3.2B of total liabilities on the balance sheet are operating items (payables, leases, deferred taxes), not borrowings. The DCF does not start from that single year — it instead starts from a projected from revenue × terminal margin of $2.21 per share to capture a full cycle.
    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.

    🐂 The Bull Case
    The most important operating factor for the bull case is that the company's drug pipeline must yield successful commercial products, leading to a stabilization and eventual growth of underlying cash flow around the modeled business rate. This would leverage the current $9.0 billion cash reserves for R&D and market expansion.
    🐻 The Bear Case
    The biggest operating risk is that revenue continues its DECLINING trend from $3.2 billion, and net income remains NEGATIVE, indicating a failure of new products to offset the decline in existing revenue streams. This would lead to a sustained contraction in per-share cash flow, worse than what the current price implies.
    📌 Signposts to watch — update your view as these print
    • Announcements of positive clinical trial results for pipeline candidates
    • New product approvals and commercialization updates
    • Trends in cash and short-term investments and operating cash flow

    The trend, in plain numbers (FY2024 → FY2025, latest reported)

    , likely due to its substantial cash and short-term investments of $9.0 billion and positive operating cash flow of $515.1 million. The market may be assigning value to future drug pipeline catalysts, which is not in the model, anticipating significant future revenue streams despite the current revenue DECLINING trend.

    Reading the last column: it is the move from today's price to each value (IV ÷ price − 1). The headline "premium/discount to model IV" measures the same gap from the value's side (price ÷ IV − 1), so the two percentages differ in size and sign by construction — e.g. a price 8% above value is a value 7.4% below price.

    Growth / Revenue DCF Low

    Extreme market premium (P/FCF 122x): market is pricing future growth far beyond current FCF. Using revenue/margin model.

    ▾ Why is DCF applicability "Low" for BNTX?
    A "Low" score means an FCF-DCF is a weaker fit for this business — not that the number is wrong, but that it deserves more skepticism. The specific drivers here:
    • The latest single-year FCF sits materially below the normalized figure the model uses, a sign of cyclicality.
    • Individual business-segment drivers are not forecast separately — the model works off consolidated cash flow only.

    Because of this, we headline the more conservative discount rate and urge you to weight the reverse-DCF, leverage, and operating trends alongside the DCF.

    In plain English: we estimate BNTX's value by projecting its owner-earnings free cash flow (operating cash flow minus capital expenditure and stock-based compensation) into the future and converting it back to what it's worth today. We start from $2.21 per share (projected from revenue × terminal margin), assume it grows 2.0% per year for about 5 years (then gradually fades), and discount everything at 9.5% — the yearly return a buyer should demand for this much risk. After that it's assumed to grow 1.6% per year forever (kept below long-run economic growth — the terminal rate fades from the near-term growth above, so a low near-term rate produces a low perpetual rate). A higher discount rate or slower growth means a lower value, and vice-versa — change any of these yourself in the calculator above.

    Revenue Growth2.0%

    What this model does NOT do: this is a consolidated owner-earnings cash-flow model. Standalone segment assumptions: none. It does not project product, services and recurring/cloud lines 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.

    Model bearish, tape neutral
    RSI?RSI — Relative Strength Index — a 0-100 momentum gauge. Above 70 = overbought; below 30 = oversold.
    Why it matters: Short-term contrarian indicator. Extreme readings often precede mean reversion, though not always.

    Data Quality & Risk Flags (6 notes — click to expand/collapse)

    Guardrail Notes (6)
    • Revenue/margin projection model used - trailing FCF may understate growth runway at current scale.
    • Terminal growth set to 1.6% — the lowest of the applicable caps (binding: 80% of near-term growth (2%)). We use one effective terminal rate everywhere on the page.
    • Price is 4.4x model IV - market may be pricing optionality, narrative catalysts, or margin expansion beyond what trailing cash flows support.
    • Price is 4.2x model IV - market may be pricing optionality, narrative catalysts, or margin expansion beyond what trailing cash flows support.
    • Operating cash flow exceeded revenue in one recent year — can be legitimate (large upfront/prepaid collections), but worth verifying the revenue concept.
    • Extreme valuation gap (P/IV 4.41): result may be dominated by model assumptions, share count issues, or sector-specific dynamics. Treat as low confidence.

    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). Latest year: 515.1M − 197.8M − 120.0M (stock-based comp) = 197.3M. 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.
