Astera Labs revenue jumps 93% as hyperscaler AI spending surges

Hyperscalers are pouring billions into AI compute, and Astera Labs is capturing a growing share of every dollar spent on server connectivity. Revenue surged 93 percent year over year to $308 million last quarter.

"Astera is focused on attaching as much dollar content as possible to every AI accelerator in a rack," management said in the earnings release, as the company prepares to report second-quarter results on Aug. 4.

First-quarter revenue of $308 million came in above the company's own expectations, with management guiding for $355 million to $365 million in the current period. The new Scorpio X 320-lane fabric switches, expected to ramp in the second half of 2026, could further boost revenue per deployment as hyperscalers build larger AI clusters that demand higher-bandwidth connectivity.

Alphabet raised its full-year capital expenditure guidance to about $200 billion and plans further increases in 2027, a demand tailwind for Astera's connectivity products. Yet the stock trades at 93 times forward earnings, pricing in years of sustained momentum that the company must deliver on.

Scorpio X Switches Target Higher Revenue Per Rack

Astera's new Scorpio X fabric switches, built with 320 lanes of high-bandwidth connectivity, target the growing density of AI server racks. As hyperscalers pack more accelerators into each cluster, the need for internal connectivity grows — and Astera's dollar content per deployment rises with it. The switches are expected to begin contributing to revenue in the second half of 2026.

Competition and Concentration Create Risk

Astera operates in a connectivity market that Broadcom and Marvell Technology are also targeting aggressively. Both companies have deeper resources and broader product portfolios, which could pressure Astera's market share over time. Customer concentration adds another risk: one buyer accounted for more than 70 percent of revenue in 2025, leaving the company exposed to any shift in that customer's procurement strategy.

Astera shares have gained about 70 percent this year, reflecting optimism about the AI infrastructure buildout. But at 93 times forward earnings, the stock already prices in sustained growth. The Aug. 4 earnings report will test whether the company can deliver on those expectations — and whether the Scorpio X ramp can justify the premium.
