How to read GOSS (pre-profit growth)

This company is reinvesting instead of generating profit, so a standard DCF cannot price it. The useful question is whether the growth the market is paying for is achievable — and whether the company can fund itself until then.

Where to start — the sections that matter most for this stock
  1. 1 Reverse-DCF — the growth the price demands ↓
    It shows exactly how fast the business must grow to justify today's price. Compare that to what comparable companies have actually achieved.
  2. 2 Cash runway ↓
    Can it reach profitability before it has to raise money and dilute shareholders?
  3. 3 Interactive calculator ↓
    Set your own growth + margin assumptions and see what the business would be worth if you are right.
Or — what are you trying to decide?
A note on process: fear-driven decisions — including fear of missing out — tend to be the expensive ones. A stock up 10% a day for three days is excitement, not evidence. Whichever reader you are, the data below is there to be checked before anything is decided.
🚀
"It's surging — should I chase it?"
The momentum / FOMO trade. Before you chase, see whether the people who know it best are quietly selling into the rally.
🏷️
"Is it a cheap bargain?"
The deep-value trade. How far below assets and our value it trades — and whether it's cheap for a reason.
ⓘ Using the right valuation lens for this business type

Standard DCF doesn't fit GOSS 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 pharmaceuticals. Reverse DCF + Football Field also work as cross-checks.

ⓘ Why does GOSS trade at $10.70?

Gossamer Bio, Inc. has 228.5 million shares outstanding. At $10.70 per share, the market values all outstanding GOSS equity at $2.4 billion. That's market capitalization, not enterprise value — enterprise value also accounts for debt and cash (GOSS 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.

VALUATION RANGE — CROSS-METHOD CHECK

Football field: where does the price sit?

Different valuation methods produce different fair-value ranges depending on assumptions. Plotting them together lets you see at a glance whether the current price is reasonable across approaches, or only one specific lens.

$1$3$6$9$11Current price $10.70EV / Sales (p25→p75)$0.70$2.29
The current price sits ABOVE the high end of every method. The market is paying a premium to all of these lenses — it expects materially better growth or margins than the models assume.

Industry multiples sourced from: industry: Pharmaceuticals. See the Peer Basket section below for the peer comparison and its limited-comparables caveat.

PEER BASKET — TIGHT COMPARABLES

How does GOSS stack up against its closest peers?

We take the 8 same-industry companies most similar to GOSS (similar size) and check what investors are paying for each dollar of their revenue (or profits). If GOSS 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, FCF yield (in the table) is 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)

Bold middle number = median peer. Half the peers trade above it, half below. Computed over 8 same-industry peers; implausible multiples excluded.

Peer-implied value check
Not enough clean peer EV/Sales multiples to derive a reliable median (some were dropped as implausible/outliers). The EV/EBIT and FCF-yield rows above are the better read here; also lean on the DCF.

⚠️ 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.

FINANCIAL HEALTH SCREENS

Bankruptcy + quality screens

Cheap stocks can be cheap for a reason. These screens warn when a low valuation comes paired with structural fragility.

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.
Reference: > 3.0 = safe zone · 1.81–3.0 = grey zone · < 1.81 = distress zone
Full explanation →
2.71
Grey zone

Grey zone — a mixed, inconclusive band under the classic thresholds. A warning to verify the recent trend, not a probability of failure.

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.

Piotroski-style checks (partial — not a standard F-score)
1 passed · 7 failed · 1 n/a
Partial result, not a standard F-score: 1 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 -$170.4M 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 -$171.3M (was -$3.5M 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 profit
    Operating cash flow -$171.3M vs net income -$170.4M.
    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 improving
    Return on assets -98.9% vs -17.9% 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)
    The filing reports no interest-bearing debt in either year (total assets $172.2M).
  • ✗ Short-term liquidity (current ratio)
    Current ratio 2.64x vs 6.88x a year ago.
    Why this matters: The current ratio compares assets it can turn to cash within a year against bills due within a year. Below 1.0 means it may struggle to cover near-term obligations.
  • ✗ Share count (dilution)
    Share count rose 1.0% (226.2M → 228.5M 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 0.28x vs 0.36x 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.

Cash Runway
3 mo
CRITICAL — under 6 months of cash

Plain English: the company holds about $38M in cash and is burning roughly $171M/year in operations. At that pace, the cash lasts 3 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.

INTERACTIVE — TWEAK YOUR ASSUMPTIONS

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 Rate?Discount 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
Full explanation → (the annual return you demand for single-stock risk) and terminal growth; the value updates live so you can see whether the stock looks cheaper or richer. The discount rate starts at 10.0%, the figure our model used for GOSS. Open Advanced to also change beta, growth and the rate path.

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.

4.5% (risk-free)9-10% normal18% (deep-risk)
0%2-3% (GDP)5% (rarely sustainable)

A full intrinsic value isn't shown for GOSS 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)
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 think GOSS can grow revenue for ~5 years, then fades to terminal.
For a pre-profit company: the % of revenue that eventually becomes free cash flow once mature. (Our published value uses the sector norm.)

    Gossamer Bio, Inc. The market may be paying up for potential future drug pipeline catalysts, which are not captured in the backward-looking model. The company has negative net income and operating cash flow, indicating it is a cash-burner. The #1 quantifiable risk is the persistent negative operating cash flow, which has been negative for 5 consecutive years.

    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.

    GOSS Gossamer Bio, Inc. stock anatomy showing per-share revenue, operating expenses, free cash flow, and debt
    −351.5%
    loss
    Where each $1 of revenue goes
    For every $1 of revenue, GOSS currently loses 351.5¢ — 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 $11) represents $0.21 of revenue per share per year, $0.75 lost per share per year, and $0.80 of cash burned per share (negative free cash flow) from the latest fiscal year. The filing reports no interest-bearing debt — the 295.0M of total liabilities on the balance sheet are operating items (payables, leases, deferred taxes), not borrowings.
    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.

    THE KEY DEBATE

    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 company's drug candidates must achieve positive clinical trial results and progress towards regulatory approval to justify the current premium valuation.
    🐻 The Bear Case
    Continued negative operating cash flow, which has been negative for 5/5 years, implies ongoing reliance on external financing and potential dilution if not reversed.
    📌 Signposts to watch — update your view as these print
    • Announcement of Phase 2/3 clinical trial results
    • Updates on regulatory submissions
    • New partnership or licensing agreements
    MOMENTUM — WHAT'S GETTING BETTER & WORSE

    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.

    ⚠ Worsening
    • Revenue fell -58% to $48.5M.
    • Free cash flow is negative at -$181.9M — the cash burn widened vs last year.
    • Still unprofitable at -$170.4M — loss widening.

    Nothing was clearly improving year-over-year.

    No discounted-cash-flow value for this filer This company's reported free cash flow is negative, so a discounted-cash-flow valuation has no positive cash stream to discount. That is a fact about the business, not missing data — the reported figures below are complete.

    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 prices Gossamer Bio at a premium of +147% to the model, likely assigning value to its drug pipeline optionality, which is not in the model. Despite negative net income and operating cash flow for the latest period and 0/5 years, the market may be anticipating future successes from its clinical-stage assets. The falling long-term debt from $29M to $0M could also be perceived positively, suggesting a cleaner balance sheet for future development.

It does not project its revenue segments independently; their combined effect is embedded in the historical revenue and cash-flow trend the model extrapolates.
