Most Popular Narrative: 21.6% Undervalued

Analysts’ most closely watched narrative sets a fair value significantly above Astera Labs’ last close. This perspective is based on accelerating revenue and profit margin expansion through strengthened relationships with hyperscale customers.

*Strong early engagement with hyperscalers and AI platform providers on open, interoperable standards like UALink (which are still in the early adoption phase with projected ramp in 2027 and beyond) enables Astera Labs to capture the industry's shift toward open, multi-vendor AI Infrastructure 2.0. This ensures exposure to significant long-term market expansion and incrementally larger addressable markets, positively impacting revenue growth rates and future margin potential as adoption accelerates.*

Another View: Multiples Paint a Pricier Picture

While the fair value model suggests Astera Labs is undervalued, traditional price-to-earnings analysis tells a different story. The company trades at 131x earnings, which is well above both the industry average of 35.8x and its fair ratio of 46.1x. Such a premium highlights significant valuation risk if future growth slows. Do these multiples reflect lasting demand, or is there downside if expectations reset?
