The five investor questions
2024–2025 (latest 2 aligned FYs; v3 window cap 5): revenue $3M to $4.6M, increasing; diluted EPS -1.65 to -1.35, increasing. Latest-filed diluted EPS remains usable for Business Trend, but an integer share-count change lacks enough evidence to confirm a comparable EPS basis; valuation growth therefore stays at 0%. Two-year history is scoreable but carries less confidence than a full-cycle record.
Not enough years of gross-margin data to score pricing power.
Median ROIC -176.8%, above the 12% hurdle in 0% of years.
Net cash position — no leverage risk.
Owner earnings trend unclear, share count growing (dilution).
The pricingPower component abstained: Not enough years of gross-margin data to score pricing power. The other four 20% weights were renormalized over the scored 80%.
Price vs. conservative owner-earnings floor
A cautious baseline, not a price target: what the shares may support if normalized owner earnings simply hold steady.
- Owner earnings (normalized)
- Not reported
- Owner-earnings floor / share
- Unavailable — insufficient owner-earnings data
- Capped-growth comparison / share
- Unavailable — insufficient growth-model data
- Recent price
- $3.02
- Price vs. owner-earnings floor
- No price data
This floor assumes trailing owner earnings persist — unreliable for declining businesses. The recent FY revenue series does not trigger the three-consecutive-declines flag.
Cohort context: median current price is 232% above the floor across 48 of the current top 50 companies by Moat Score with both values.

Model details under moat-index@3.0.0: zero-growth floor 11.1×, capped-growth comparison at no more than 18×; 9% discount rate; high-end growth 0% (capped at 4%) using min(5y revenue CAGR, 5y diluted-EPS CAGR), clamped to 0%–4%; maintenance capex uses min(capex, D&A); abstain when D&A is unavailable. This is a disclosed model range, not intrinsic value as fact.
7 years of fundamentals
The business, in plain English
Across the filed record, revenue shrank from $5.2M (FY2020) to $4.6M (FY2025) — about −2.3% a year compounded over 5 years.
It earned −284.6% on invested capital in FY2025, with a median of −176.8% across 3 filed years. The Returns on Capital filter above scores it 0/100.
PRME's filings don't disclose total debt in a form the methodology can use, so leverage is treated as unmeasured — never assumed to be zero.
This breakdown is generated from the filed numbers and sub-scores above — no outside narrative, no estimates. Where a filing doesn’t disclose an input, the sentence that would need it is omitted instead of guessed.
Not disclosed in PRME’s filings for these years — we don’t estimate it.
Gaps in a line mean that item isn’t in PRME’s filings for that year — the series is never interpolated or estimated. The Table view lists every filed value, including operating and net margins, total debt, and share count.
Moat Score history
Breaks in the line mark methodology upgrades — readings scored by different engine versions aren’t compared, so a level shift there isn’t a change in the business.

Scores are logged append-only and never overwritten — this record can’t be backfilled, which is exactly why it’s worth keeping.
Track record
How Prime Medicine, Inc.’s moat rated in each of the years we can reconstruct from its filings — scored only on what was knowable at the time — and what its price and returns did afterward. The score never saw a price; the two are joined only in hindsight, for education, not as a signal.
How to read this: each dot is what the engine would have scored PRME on that December 31; the line below is its total-return price path (dividends reinvested) in the years since.
Two tracks, one timeline: the score has its own 0–100 scale (top), the price its own 100-based scale (bottom) — never a shared axis. The price path is a total-return (dividends reinvested) index built from the same data the forward returns use; gaps in the score line are years with no reconstructed rating (see the table for why). The Table view carries every value.
What followed, in the years it rated Wide
In the reconstructed history shown, PRME did not rate Wide-moat in any year, so there is no wide-moat track record to report. That absence is itself the honest answer — we don’t manufacture a comparison where the rating never earned one.
