Astera Labs, Inc. - Common Stock

The investment conclusion is that the market is prepaying for an unvalidated rack-scale AI interconnect platform, as current EV/TTM revenue of 50.8x and TTM GAAP P/E of 194.5x leave little cushion for execution shortfalls. Customer concentration is severe, with five direct customers accounting for 90% of Q1 revenue, and the Amazon warrant arrangement of up to USD 6.5 billion represents a ceiling condition rather than a minimum purchase commitment. The DCF, which explicitly treats SBC as an operating cost and uses 195 million diluted shares, yields approximately USD 210 even at aggressive 8.5% WACC and 5.0% perpetual growth, still below the current price.

The reverse DCF requires approximately 31% annual revenue growth through 2035, reaching USD 17.5 billion, to justify the current valuation. Material risks include competition from Broadcom, Marvell, and Credo; TSMC and Taiwan geopolitical supply chain concentration; SBC and warrant dilution; and the absence of buybacks to offset share count growth. Positive catalysts include Q2 revenue above USD 365 million, Scorpio X-Series volume production ramping in H2 2026, and improved product-level revenue transparency.
