Ambarella (AMBA): Revisiting Valuation After Upgraded 2026 Revenue Outlook and Narrower Quarterly Loss

Simply Wall St · 2d ago

Ambarella (AMBA) just delivered a quarter that combined faster sales growth with a slimmer loss, and then immediately raised its full year revenue outlook to a record range, which is what has investors paying attention.

See our latest analysis for Ambarella.

The latest earnings beat and upgraded guidance come after a choppy spell, with a 30 day share price return of minus 14.34% and a five year total shareholder return of minus 16.23%. This positive surprise could mark a turn in sentiment.

If Ambarella’s update has you thinking about what else could rerate on stronger growth signals, it might be a good time to explore high growth tech and AI stocks.

With revenue accelerating, losses narrowing and the share price still sitting at a steep discount to analyst targets, the big question now is simple: Is Ambarella undervalued, or is the market already pricing in that future growth?

Most Popular Narrative Narrative: 24.5% Undervalued

With Ambarella last closing at $74.10 against a narrative fair value near $98, the current gap assumes a very different future than the market does.

The company's unified architecture and software development platform enable efficient support and rapid customer onboarding across a growing array of applications, which lowers incremental operating expenses and strengthens operating leverage as revenue grows. The robust pipeline of new product launches and design wins in autonomous mobility (including automotive safety, ADAS, and telematics) are expected to realize significant long term, high volume opportunities, improving multi year revenue visibility and supporting future revenue inflection points as OEM decision cycles play out.

Curious how steady double digit revenue growth, margin expansion, and a punchy future earnings multiple all combine into that upside case? The full narrative unpacks the exact assumptions, the timing of the expected inflection, and why future profitability is treated more like a mature chip leader than a turnaround story.

Result: Fair Value of $98.09 (UNDERVALUED)

However, concentrated IoT exposure and slower than hoped automotive design wins could easily derail the upbeat growth and valuation assumptions embedded in this narrative.
