Is Ambarella’s Rally Sustainable After Recent AI Chip Demand Surge?

So, you’re wondering what to do with Ambarella’s stock after its recent run. Maybe you’ve noticed the 41.9% surge over the past year, or the solid 13.4% jump just in the last week. Long-term holders have done alright too, with a 52.9% gain over three years and 44.7% over five. Clearly, momentum has returned in a big way. This is not just because of general market buzz. Tech-focused investors are re-evaluating image processing and AI hardware companies, with Ambarella benefiting from strengthened sentiment around autonomous vehicles and next-generation security tech.

But what about valuation? If you’re worried you’ve missed the train, or the price is running ahead of fundamentals, you’re not alone.

Approach 1: Ambarella Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow (DCF) model estimates what a company is worth by projecting its future free cash flows and discounting them back to today's value. This approach provides an estimate of intrinsic value based on how much cash the business is expected to generate in the years ahead.

For Ambarella, the most recent free cash flow stands at $36.96 million. Analysts have offered detailed estimates through 2027, suggesting that free cash flow could increase steadily, reaching $140.2 million by 2030. Years beyond the analyst window are extrapolated based on growth trends. All forecasts are converted to dollars, matching the company’s reporting currency.

According to the DCF model, Ambarella's estimated intrinsic value per share is $65.09. This value represents a 27.0% premium compared to the current share price, which means the stock appears overvalued using this methodology. The implication is that Ambarella’s future growth may already be reflected in the current price, so further upside would require a new catalyst or performance beyond the present projections.

Result: OVERVALUED

Approach 2: Ambarella Price vs Sales

The Price-to-Sales (P/S) ratio is often considered a reliable valuation metric for tech companies like Ambarella, especially when earnings are negative or volatile and revenue growth remains strong. While Price-to-Earnings is common for established, profitable firms, the P/S ratio provides a useful sense of value for businesses at earlier growth stages or those investing heavily in future expansion.

Growth expectations and perceived risks play a significant role in determining what constitutes a reasonable P/S ratio. Higher expected sales growth can justify above-average multiples, while greater uncertainty or risk often leads to a discount. Context from the company’s peer set and industry benchmarks helps set these expectations, but each company's unique profile means the numbers can vary widely.

Currently, Ambarella’s P/S ratio stands at 10.1x. This is more than double the peer average of 4.85x and is also notably higher than the Semiconductor industry average of 5.19x. At face value, Ambarella appears expensive relative to its direct competitors and the broader sector.

However, Simply Wall St takes this analysis a step further with its proprietary “Fair Ratio.” This metric estimates what a reasonable P/S multiple would be for Ambarella, factoring in anticipated earnings growth, profit margins, industry, company size, and risks. This offers a more tailored view than industry or peer comparisons alone, which may overlook these specific factors. For Ambarella, the Fair Ratio is calculated at 5.70x.

Comparing the Fair Ratio (5.70x) to Ambarella’s actual P/S ratio (10.1x), the stock is trading at a meaningful premium to its fundamentals according to this framework.

Result: OVERVALUED
