Another View: Astera Labs Through The P/E Lens
While the most followed narrative points to Astera Labs being around 7.6% undervalued, the P/E picture looks very different. At about 145.7x earnings, compared with 47.2x for the US semiconductor industry and a 65.9x peer average, the stock trades at a very large premium to both groups and to an estimated fair ratio of 54.5x.
