Most Popular Narrative: 5.6% Undervalued

Ambarella’s last close of $85.03 sits just below the narrative’s fair value target of $90.05, highlighting optimism about the company’s growth trajectory and future margins as edge AI markets expand. This sets up a pivotal debate around whether projected business drivers can sustain the recent rally.

"Sharply increasing demand for AI-powered edge devices, including portable video, robotics (notably aerial drones), and edge infrastructure, has led to a rapid expansion of Ambarella's addressable markets, as evidenced by record edge AI revenue and multiple recent, diversified design wins. This is catalyzing strong, sustained revenue growth and positions Ambarella to benefit further as additional vertical applications for edge AI proliferate."

Another View: Market Ratios Tell a Different Story

Looking at Ambarella through the lens of market ratios reveals a more expensive picture. Its price-to-sales ratio stands at 10.4x, which is nearly double both the US Semiconductor industry average of 4.8x and the calculated fair ratio of 5.5x. This suggests investors are paying a premium for growth that may already be priced in. Could Ambarella’s multiples come under pressure if expectations shift?
