The five investor questions

43

2022–2026 (latest 5 aligned FYs; v3 window cap 5): revenue $332M to $391M, increasing; diluted EPS -0.72 to -1.78, decreasing.

99

Median gross margin 60.7% over 10y, very stable.

7

Median ROIC -15.2%, above the 12% hurdle in 20% of years.

55

Net cash position — no leverage risk.

24

Owner earnings changed trend unclear over up to the ten most recent annual observations.

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.

17 years of fundamentals

The business, in plain English

AMBARELLA, INC. booked $391M of revenue in FY2026 in the Technology sector and kept 59.2% of it as gross profit — a high-margin business by that measure. After every other cost, −19.4% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $94.7M (FY2011) to $391M (FY2026) — about 9.9% a year compounded over 15 years.

It earned −16.1% on invested capital in the latest filed year, FY2026. Across the full 14-year measurable filed record, median ROIC was −9.1%. Over the v3 recent window (10 measurable filed years), median ROIC was −15.2%. The Returns on Capital filter above scores it 7/100.

AMBA's latest filed year, FY2026, 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 (99/100) and Returns on Capital the weakest (7/100), which is how AMBA lands at 46/100 — a Shallow 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 AMBARELLA, 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 2012–2025, 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 AMBA on that December 31; the line below is its total-return price path (dividends reinvested) in the years since.

0406080100WideNarrowShallowNo moatPoint-in-time Moat Score1002005001,0002,000Indexed price · log scale (2013 = 100)201220152018202120242026

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 6 years AMBA rated Wide-moat (2013, 2014, 2015, 2016, 2017 and 2018), the median forward total return that followed — measured only after each year’s filings were public — was:

  • 1 year 12% vs the S&P 500’s 12% (price basis) · median over 6 years
  • 3 years 34% vs the S&P 500’s 34% (price basis) · median over 6 years
  • 5 years 47% vs the S&P 500’s 71% (price basis) · median over 6 years

These are medians computed from the data, not a claim about any one year. The company figures are total returns (dividends reinvested); the S&P 500 is the price-only ^GSPC index, which excludes dividends and so understates the index — the gap flatters the company. A quality rating is not a return forecast, and past returns don’t predict future ones. Educational only, not investment advice.
