Astera Labs Stock Jumps 16% on AI Connectivity Outlook

(Bloomberg) — Shares of Astera Labs Inc. (NASDAQ:ALAB) surged more than 16 percent Tuesday, touching a high of $255.96 after company executives outlined a bullish growth forecast fueled by surging demand for artificial intelligence infrastructure and the company’s expanding portfolio of connectivity solutions.

“We reported $308 million in revenue in its most recent quarter, up 14% sequentially and 93% year over year,” Chief Executive Officer Jitendra Mohan said at J.P. Morgan’s Technology and Media Communications Conference, adding that the company guided to $360 million for the next quarter at the midpoint.

The growth highlights the critical role of specialized hardware required to connect processors and memory inside data centers running AI workloads. Astera’s results showed earnings per share of $0.61, a substantial increase from about $0.10 around its March 2024 IPO, reflecting strong operational performance as it scales production.

At stake is a rapidly expanding market for AI-specific hardware, with investors trying to identify key suppliers beyond high-profile chip designers. The company’s strategy to be “the Switzerland of connectivity” for both merchant GPUs and custom chips positions it to capture growth across the entire AI hardware sector, which could insulate it from the dominance of a single chip architecture.

Scorpio and UALink to Drive Future Growth

Astera’s Scorpio product family is quickly becoming its main growth engine, with management expecting it to be the company’s largest product line by year-end. The Scorpio P-Series, which accounted for about 15 percent of revenue last year, is set to ship to two new hyperscaler customers in the second half of the year, with ramps continuing into 2027. The company also noted it has ten customer engagements for its higher-radix Scorpio X-Series switches across hyperscalers and AI platform providers.

Further cementing its neutral-provider status, Astera is developing products for the UALink protocol, an open standard for scale-up applications supported by competitors like AMD and major customers like AWS. With platforms from these companies expected to ramp in 2027, Astera’s on-track development could lead to significant design wins. This approach contrasts with proprietary interconnects like Nvidia’s NVLink, for which Astera is also a collaborator, working on a custom silicon project expected to ramp in 2027.

Optics and CXL Emerge as Long-Term Catalysts

As AI clusters grow, the physical limits of copper wiring are forcing a shift to optical interconnects, a market some research suggests could reach $146 billion by 2040. While CEO Jitendra Mohan noted copper will remain dominant at the rack level, he said optics will be necessary for multi-rack connections. Astera is positioning for this shift through its acquisition of aiXscale, targeting initial revenue from near-packaged optics (NPO) in 2027.

This places Astera in a competitive field with established optical players like Broadcom, Cisco (via its Acacia acquisition), and Marvell Technology. However, Astera’s focus on silicon photonics and CXL memory controllers offers a differentiated path. The company’s Leo CXL memory controllers are gaining traction for new use cases like KV Cache offload, which addresses memory bottlenecks in large language model inference. A custom version of Leo for a hyperscaler customer highlights the demand for such solutions.

For investors, Astera Labs presents a specific bet on the increasing importance of data connectivity in the AI era. While the AI trade has become crowded, according to a recent Bank of America survey, Astera’s focus on the interconnect bottlenecks provides a distinct growth narrative. The company’s long-term model targets a 70 percent gross margin, which CFO Desmond Lynch called “very rich for a semiconductor business,” reflecting the high value customers place on solving these complex connectivity challenges.
