ALAB Benefits From Strong UALink Growth: Will the Momentum Continue?
Read MoreHide Full Article
Key Takeaways
ALAB is seeing rising UA Link interest, with hyperscalers and AI firms in active RFP and RFQ stages.
UALink supports high-bandwidth, low-latency scale-up for AI clusters using Astera Labs' fabric design.
ALAB expects UA Link to boost PCIe scale-up revenue, with a multibillion-dollar opportunity by 2029.
Astera Labs (ALAB - Free Report) is benefiting from strong growth in UALink, an open standard scale-up connectivity protocol designed to address the increasing demands of AI infrastructure. UALink combines the memory semantics of PCIe and the fast speed of Ethernet, but is devoid of the software complexity and performance limitations of Ethernet.
The company has experienced strong customer activity surrounding UALink. Several top hyperscalers and AI platform providers are currently involved in the RFP (Request for Proposal) and RFQ (Request for Quotation) stages to match their designs and applications with UALink’s capabilities.
UALink’s ability to support higher bandwidth and ultra-low latency makes it ideal for scaling AI clusters. Astera Labs is leveraging its flexible fabric architecture and hands-on experience with scale-up networks to develop UALink products that meet diverse customer needs. This positions the company to capture a significant share of the growing AI infrastructure market, which is forecasted to see hyperscaler CapEx surpass $500 billion by 2026.
The adoption of UALink is expected to be meaningfully additive to Astera Labs’ PCIe scale-up revenues, providing a significant growth opportunity. ALAB expects to deliver UALink solutions in 2026 to solve scale-up connectivity challenges for next-generation AI infrastructure. The growing proliferation of UALink is expected to be a multibillion-dollar additional market opportunity for Astera Labs by 2029.
ALAB Suffers From Stiff Competition
Astera Labs is facing stiff competition from other industry players, such as Broadcom (AVGO - Free Report) and Marvell Technology (MRVL - Free Report) , which are also making strong efforts in the AI infrastructure market.
Broadcom is benefiting from strong demand for its networking products and custom AI accelerators. Broadcom’s AI revenue grew 65% year over year in fiscal 2025, reaching $20 billion. This growth is driven by AI semiconductors and infrastructure software, with AI revenue expected to double year over year to $8.2 billion in the first quarter of fiscal 2026.
Marvell Technology’s expanding portfolio has been noteworthy. In December 2025, Marvell Technology announced broad industry adoption of its Alaska P PCIe 6 retimer family, enabling low-power, high-speed, low-latency connectivity across AI accelerators, GPUs, CPUs, SSDs, and CXL devices in advanced data centers. The 5nm PAM4-based retimers support 64 GT/s PCIe 6 links, compensating for up to 40 dB channel loss while scaling AI compute fabrics within servers, racks and clusters.
ALAB’s Share Price Performance, Valuation, and Estimates
ALAB shares have risen 91% in the past six-month period, outperforming the broader Zacks Computer & Technology sector’s return of 19.5%. The Zacks Internet - Software industry has declined 7.6% in the same time frame.
