The five investor questions

50

2022–2025 (latest 4 aligned FYs; v3 window cap 5): revenue $34000 to $130000, increasing; diluted EPS -9.70 to -1.91, increasing.

70

Median gross margin 85.9% over 7y, variable.

0

Median ROIC -1200.5%, above the 12% hurdle in 0% of years.

28

Net debt/EBITDA n/ax, interest coverage -113x.

44

Owner earnings changed trend unclear over up to the ten most recent annual observations, share count n/a.

Price vs. value if growth stopped today

This zero-growth estimate assumes trailing owner earnings persist — unreliable for declining businesses. The recent FY revenue series does not trigger the three-consecutive-declines flag.

Among the current top-score group, the median current price is 239% above the zero-growth estimate across 48 of the current top 50 companies by Moat Score with both values.

This is a disclosed model range, not intrinsic value as fact.

10 years of fundamentals

The business, in plain English

Across the filed record, revenue shrank from $1.4M (FY2017) to $130000 (FY2025) — about −25.7% a year compounded over 8 years.

ROIC is not available for the latest filed year, FY2025. Across the full 3-year measurable filed record, median ROIC was −1200.5%. Over the v3 recent window (3 measurable filed years), median ROIC was −1200.5%. The Returns on Capital filter above scores it 0/100.

SER's latest filed year, FY2025, doesn't disclose total debt in a form the methodology can use, so current leverage is treated as unmeasured — never assumed to be zero.

Put together: Pricing Power is the strongest of the five filters (70/100) and Returns on Capital the weakest (0/100), which is how SER lands at 38/100 — a None moat.

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.

Insider activity

Form 4 reports mix P/S market or private transactions with compensation-plan mechanics. Activity casually described as “insider selling” can include compensation mechanics; awards, tax withholding, and option exercises are shown by their exact filed class here, never collapsed into “Bought” or “Sold.”

These are disclosed filing facts and arithmetic aggregates, not a signal or verdict.

This machine-readable surface covers SEC ownership filings from 2003; it does not represent earlier paper-era records.

Track record

How Serina Therapeutics, 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.

Point-in-time scores 2019–2025, one methodology version · reconstructed from filings on file each Dec 31 — never with hindsight

Point-in-time Moat Score (dot colored by tier)Indexed price (total-return (dividends reinvested))Rated Wide-moat that year

How to read this: each dot is what the engine would have scored SER on that December 31; the line below is its total-return price path (dividends reinvested) in the years since.

0406080100WideNarrowShallowNo moatPoint-in-time Moat Score25102050100Indexed price · log scale (2019 = 100)20192021202320252026

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, SER 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.

How has SER's Moat Score changed over time?
The record logs 15 readings since Jul 17, 2026; the latest reads 38.3 out of 100 (no moat). No tier changes on record yet. (Methodology or normalizer upgrades on Jul 20, 2026, Jul 23, 2026, Jul 26, 2026 re-based the score; readings across versions aren't compared.)
