Astera Labs ALAB is benefiting from strong demand for its PCIe solutions, which have also been a major growth driver. In the fourth quarter of 2025, the company reported revenues of $270.6 million, marking a 17% sequential increase and 92% year-over-year growth.
Astera Labs’ product portfolio, including Scorpio, Aries and Taurus, has been a key catalyst. A standout performer in ALAB’s portfolio is its Aries PCIe 6 DSP retimer solutions, which are currently the only PCIe 6 DSP retimer products shipping in high volume. The Aries portfolio saw 70% year-over-year growth in 2025, driven by the increasing deployment of custom AI accelerators at major hyperscalers. With the PCIe 6 transition cycle still in its early stages, ALAB expects further growth as more customers launch PCIe 6 capable AI accelerators and systems in 2026 and beyond.
The Scorpio P-Series family has also been a key growth driver, contributing more than 15% of revenues in 2025. As the only PCIe 6 fabric available in large quantities, Scorpio P-Series is poised to grow in 2026, with shipments to more hyperscalers for next-generation AI platforms. The Scorpio X $TWTR-Series is likely to move to high-volume production in the second half of 2026, which will further boost revenues.
ALAB's strong demand for PCIe solutions, coupled with its leadership in the AI connectivity space, positions the company for significant upside. Astera Labs expects first-quarter 2026 revenues between $286 million and $297 million, up approximately 6% to 10% year over year.
