Astera Labs’ momentum has cooled after a strong stretch earlier in the year as the market weighs its growth narrative. Despite recent announcements with Microsoft and robust demand signals around AI-optimized products, the 1-year total shareholder return stands at an impressive 33.8%, even as the share price has pulled back nearly 12% over the past month. This pattern suggests investors are taking a breather following rapid gains. At the same time, the company’s positioning in cloud infrastructure and data center expansion keeps long-term prospects firmly in focus.

With shares pulling back but strong demand signals in AI and cloud infrastructure, is Astera Labs undervalued by the market or is all of that future growth already reflected in the current price? Could this be a buying opportunity, or is caution warranted?

Most Popular Narrative: 29% Undervalued

Astera Labs’ most widely followed narrative places its fair value at $196.83, well above the last closing price of $139.29. The narrative’s bullish foundation draws on accelerating revenue, increasing margins, and momentum with key 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: Earnings Multiple Raises Caution

While the most popular narrative suggests Astera Labs is undervalued, the market signals something different. Based on its price-to-earnings ratio of 118.3x, Astera Labs appears much more expensive than both its US semiconductor peers (32.8x) and the fair ratio of 45.6x. This wide gap suggests investors are paying a premium based on lofty future growth hopes. Will the fundamentals catch up, or does this premium carry extra risk?
