Company & revenue

About Ambarella, Inc.

Primary reporting period: 2026-01-31 · Research updated Oct 12, 2026. A research update is not a new financial filing.

Financial risk observations and what to check

These are saved observations about business performance, not predictions. Review the company filings alongside the interpretation below. Latest stored financial period end: 2026-07-31.

Total debt increased 267.3% versus the same quarter last year.

Compare the added borrowing with available cash, cash generation and maturities. A percentage increase from a small starting balance can look large without measuring the full debt burden.

WSS View

The quick read

The overall Wall Street Score is low across its combined quality, valuation and risk inputs. This can reflect an expensive share price, business weaknesses, or both; check Company Quality and the category breakdown before drawing a conclusion.

At today’s price, the WSS valuation framework currently reads as less attractive based on the available valuation and market data.

The model outlook is currently cautious.

What we like
  • •Recent buyback activity is present
What to watch
  • •Valuation is a weaker part of the current profile
  • •Revenue fundamentals are weak
  • •Debt / balance-sheet profile needs attention
  • •Asset quality is a weaker factor

Momentum & Volatility Signals

Two different market-behavior signals. Momentum measures direction and trend strength. Volatility measures how large and unstable the price moves are, regardless of direction.

Normal movement

Momentum = Where is it going?

A high momentum score means price has been trending upward with confirming short- and medium-term strength. A low score means downward or weakening momentum.

Volatility = How violently is it moving?

A high volatility score means larger, less stable price swings. It can happen while a stock is rising or falling, so high volatility is not automatically bullish or bearish.

Important: the volatility score above is based on realized price volatility. Implied volatility (IV) comes from options prices and represents the market's expected future movement. Wall Street Score will keep IV separate and will only display it when a verified options-chain feed is available.
