ASP Isotopes Inc. (ASPI) Stock Analysis
ASP Isotopes Inc.
▾ What's in the 31/100 risk score? (higher = riskier)
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.
How to read ASPI (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.

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.

Set your own growth + margin assumptions and see what the business would be worth if you are right.
Standard DCF doesn't fit ASPI 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 specialty chemicals. Reverse DCF + Football Field also work as cross-checks.
⚠ We found only 2 genuine same-industry (Specialty Chemicals) comparables — fewer than the 4 we require for a reliable median. The 8 names in the table below therefore include 6 broader Basic Materials names marked fallback, whose business models and margins differ — which is why any median below is computed over that wider set, not over true comparables. So we do not derive a peer-implied share value here. Read the multiples as rough context only.
How does ASPI stack up against its closest peers?
Ideally we compare ASPI 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 → |
0.6x / 2.5x / 3.8x |
| 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 → |
2.0x / 12.7x / 14.5x |
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 →
We can't produce a trustworthy Altman Z here: retained earnings weren't separately reported in our data, so a core input would have to be fabricated. Rather than show a categorical "distress" verdict from an invented number, we mark it unavailable. Judge financial health from the leverage, cash position, and the measurable Piotroski checks instead.
Why it matters: High score = fundamentals improving. Low score = deteriorating. Especially powerful for filtering cheap stocks: cheap + high F-score historically outperforms; cheap + low F-score is often a value trap.
Reference: 7–9 = strong · 4–6 = mediocre · 0–3 = weak

▾ The checks — what passed, what didn't (and what we couldn't measure)
-
✗ Positive net incomeNet income -$159.8M 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 -$37.8M (was -$16.7M 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 -$37.8M vs net income -$159.8M.
-
✓ Return on assets improvingReturn on assets -32.1% vs -34.4% a year ago.
-
✗ Debt load (vs assets)Long-term debt is 2.9% of assets vs 2.5% a year ago ($14.4M of $498.0M assets).Why this matters: Rising debt relative to assets means more risk and more cash going to interest instead of shareholders. Falling debt is a sign of strengthening.
-
✓ Short-term liquidity (current ratio)Current ratio 12.23x vs 9.31x a year ago.
-
✗ Share count (dilution)Share count rose 49.1% (55.7M → 83.0M 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)Gross margin 14.3% vs 38.6% a year ago.Why this matters: Rising gross margin means stronger pricing power or lower input costs — a sign of competitive strength. Falling margin signals pressure.
-
✓ Sales per asset (asset turnover)Asset turnover 0.05x vs 0.04x 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.
Plain English: the company holds about $286M in cash and is burning roughly $38M/year in operations. At that pace, the cash lasts 7.6 yrs 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
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 ASPI. 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.
A full intrinsic value isn't shown for ASPI 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 → valuation is not meaningful for ASP Isotopes Inc. due to its negative operating cash flow and net income, indicating a cash-burning growth stage. Investors are likely focused on the company's product pipeline and future revenue growth potential rather than current profitability. The primary quantifiable risk is the continued negative operating cash flow, which could necessitate further capital raises.

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 new isotope production contracts
- Progress in product development pipeline
- Improvement in operating cash flow
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 +476% to $23.8M.
- Free cash flow is negative at -$63.5M — the cash burn widened vs last year.
- Gross margin shrank to 14% (-24 pts).
- Still unprofitable at -$159.8M — loss widening.

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 prices ASPI based on expectations for future growth and the potential of its isotope separation technologies, rather than current cash flow. The company's negative net income and operating cash flow indicate it is in a cash-burning growth phase, with investors betting on its product pipeline and eventual profitability.
Business Model & Valuation
How They Make Money
The company funds itself primarily through equity raises, given its negative operating cash flow and lack of dividends or buybacks.
Normalized FCF
Cyclical/commodity sector (Specialty Chemicals) with negative current FCF: normalized FCF uses multi-year median to smooth through the cycle.

What this model does NOT do: this is a consolidated owner-earnings FCF model. Standalone segment assumptions: none. It does not project production volumes, realized commodity prices and unit cash costs 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
The company has been profitable in 0 out of the last 4 years, with negative net income and operating cash flow in the latest period.
Geography & Markets
ASP Isotopes Inc. is headquartered in the United States, with its operations and customer base primarily focused within North America and potential for expansion into global markets, though specific geographic revenue mix is not available.

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: -37.8M − 9.7M − 16.0M (SBC & adj.) = -63.5M. This is the same owner-earnings FCF definition the valuation model uses, though the DCF's starting value is a mid-cycle estimate (median operating cash flow less estimated maintenance capex and stock compensation — by design NOT the table's FCF, which deducts every year's full capex), not this single year.
