Why Ambarella's latest quarter matters for stock watchers

Ambarella (AMBA) just reported fiscal second quarter results that combined higher sales with a narrower net loss. The company also issued new revenue guidance and announced new AI focused distribution and services partnerships.

The quarter brought sales of US$108.13 million and a net loss of US$6.69 million. Management provided guidance for third quarter revenue of US$115 million to US$124 million and highlighted expanded collaboration with Macnica and Capgemini in edge and physical AI.

Ambarella's latest updates on AI partnerships and revenue guidance arrive after a sharp pullback, with the 1 day share price return down 5.6% and the 30 day share price return down 22.9%, while the 3 year total shareholder return is still slightly positive at 4.9% despite a 21.9% decline over the past year.

Ambarella now trades well below both its own intrinsic value estimate and the average analyst target after the recent pullback. The real question is how that gap compares with the company's current fundamentals.

Most Popular Ambarella Narrative: 46.4% Undervalued

Ambarella's most followed narrative currently anchors on a fair value of $118.20 per share, which sits well above the last close at $63.38. That gap rests on a detailed view of how edge AI and automotive opportunities could filter through to revenue, margins and future earnings power.

The market is only beginning to grasp the depth of Ambarella's penetration into next-wave edge AI verticals, such as portable video, robotics, and especially edge infrastructure; increased adoption here could create multiple independent long-term revenue streams, de-risking the business model and supporting multi-year earnings growth beyond traditional video and automotive cycles.

Ambarella's unified hardware-software platform and developer ecosystem are now at a level where customer onboarding, design, and deployment cycles can be radically compressed, making Ambarella a default standard for a growing number of OEMs and enabling the company to capture increasing shares of the global shift to smart edge devices, translating to accelerating revenue and normalized net margin expansion.

Another view on Ambarella's valuation

While the narrative and analyst targets frame Ambarella as undervalued, the preferred sales multiple paints a stricter picture. The current P/S of 6.9x is higher than both the US Semiconductor sector at 6.3x and the peer average at 4.3x. It is also above the fair ratio of 5.4x, which suggests less room for error if growth or margins do not meet expectations. How comfortable are you with paying a higher multiple today based on those assumptions?
