The business, in plain English

AMBARELLA, INC. booked $390.7M 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 $390.7M (FY2026) — about 9.9% a year compounded over 15 years.

It earned −16.1% on invested capital in FY2026, with a median of −9.1% across 14 filed years. The Returns on Capital filter above scores it 7/100.

AMBA'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.

The share count rose 469.7% between FY2012 and FY2026 — existing owners have been diluted over the record. Capital Discipline scores it 24/100.

Put together: Pricing Power is the strongest of the four filters (99/100) and Returns on Capital the weakest (7/100), which is how AMBA lands at 48/100 — 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.
