The five investor questions

70

2021–2025 (latest 5 aligned FYs; v3 window cap 5): revenue $167M to $343M, increasing; diluted EPS -1.46 to -0.67, increasing.

99

Median gross margin 70.4% over 7y, very stable.

—

Not enough years of ROIC data to score returns on capital.

78

Net cash position — no leverage risk.

44

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

The returnsOnCapital component abstained: Not enough years of ROIC data to score returns on capital. The other four 20% weights were renormalized over the scored 80%.

Price vs. value if growth stopped today

A cautious baseline, not a price target: what the shares may support if normalized owner earnings simply hold steady.

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.

Model details under moat-index@3.0.0: zero-growth multiple 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.

8 years of fundamentals

The business, in plain English

AMPLITUDE, INC. booked $343M of revenue in FY2025 in the Technology sector and kept 74.0% of it as gross profit — a high-margin business by that measure. After every other cost, −25.8% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $68.4M (FY2019) to $343M (FY2025) — about 30.8% a year compounded over 6 years.

AMPL'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.

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.

Records still being gathered — partial as of retrieval Sep 3, 2026.

Among the rows shown, A/F/M acquisition, payment or withholding, and exercise or conversion rows outnumber S sale rows (4 versus 0). The filing codes alone do not establish that every such row arose from a compensation plan.

Trailing-12-month totals and the 90-day cluster result are withheld because this issuer walk is incomplete.

Track record

How AMPLITUDE, 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 2021–2025, 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 AMPL on that December 31; the line below is its total-return price path (dividends reinvested) in the years since.

0406080100WideNarrowShallowNo moatPoint-in-time Moat Score2050100Indexed price · log scale (2022 = 100)202120222023202420252026

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, AMPL 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.

(Methodology or normalizer upgrades on Jul 20, 2026, Jul 23, 2026, Jul 26, 2026 re-based the score; readings across versions aren't compared.)
