ALAB Benefits From Strong Demand for PCIe Solution

ALAB is rapidly expanding its portfolio to address the growing demands of AI infrastructure and connectivity solutions. Its product portfolio, including Scorpio, Aries, and Taurus, has been a key catalyst. In the second quarter of 2026, PCIe 6 products, including the Scorpio AI Fabric Switches and Aries Retimers, accounted for more than 50% of total revenues, highlighting the market leadership of ALAB’s Gen 6 portfolio.

The Scorpio product family delivered significant growth in the second quarter of 2026, as the X-Series began shipping in initial production volumes across multiple lane configurations. The high-radix Scorpio X-Series entered volume production and is expected to scale materially during the second half of 2026. Management expects Scorpio to become the company’s largest product family in the third quarter, one quarter earlier than previously projected. The transition will be led by the 320-lane Scorpio X-Series fabric switch, which supports larger accelerator clusters and includes hardware-based Hypercast and in-network compute capabilities.

In the second quarter of 2026, Taurus revenues grew strongly on increased unit shipments across AI and general-purpose computing platforms. The company also delivered preproduction volumes of 100-gigabit-per-lane Taurus Smart Cable Modules for 800-gigabit active electrical cables.

Astera Labs expanded its Taurus signal conditioning portfolio with 3.2T Smart Retimers and Smart Redrivers for 224G Ethernet and UALink connectivity, strengthening AI infrastructure capabilities. The new OCP-compatible design enables Smart Swap flexibility, while Unified COSMOS software adds advanced telemetry, diagnostics and intelligent link management across high-speed interconnects.

ALAB Offers Strong Q3 Guidance

Aster Labs is benefiting from strong demand for its Aries, Taurus, and Scorpio product families, all of which are expected to drive growth in the third quarter of 2026.

For the third quarter of 2026, revenues are expected to be between $540 million and $560 million. The midpoint implies sequential growth of approximately 40%, driven by the Scorpio X-Series production ramp, continued Aries PCIe 6 retimer strength and preproduction Taurus shipments for 800-gigabit Ethernet applications. The Zacks Consensus Estimate for third-quarter revenues is pegged at $405.29 million, representing year-over-year growth of 75.78%.

Management projects non-GAAP earnings between $1.16 and $1.21 per share in the third quarter of 2026. The Zacks Consensus Estimate for third-quarter 2026 earnings is pegged at 77 cents per share, which has been unchanged over the past 30 days. The figure implies a year-over-year increase of 57.14%.

ALAB Faces Stiff Competition

Despite an expanding portfolio and strong partner base, ALAB is facing stiff competition from other industry players like Marvell Technology MRVL, Cisco Systems CSCO and Credo Technology CRDO. These companies are all expanding their footprints in the AI infrastructure space.

Marvell Technology’s expanding portfolio has been noteworthy. In June 2026, Marvell Technology introduced the Teralynx T100, the industry’s first 102.4 Tbps AI-optimized switch silicon, delivering up to 25% lower power consumption and ultra-low latency to improve efficiency and scalability in large AI data center networks.

Cisco Systems has been integrating AI into its product portfolios across networking, security, collaboration and observability. Strong demand for Cisco Systems’ products in developing AI infrastructure has been a game-changer for the company. In the third quarter of fiscal 2026, AI infrastructure orders taken from hyperscalers totaled $1.9 billion in the reported quarter compared with $600 million in the year-ago quarter. Cisco Systems raised its fiscal 2026 hyperscaler AI infrastructure order outlook from $5 billion to $9 billion, and increased expected AI infrastructure revenues from $3 billion to $4 billion. 

Credo Technology’s expanding portfolio has been noteworthy. In May 2026, Credo Technology completed its acquisition of DustPhotonics, adding industry-leading silicon photonics technology to strengthen its optical interconnect portfolio across 800G, 1.6T and 3.2T solutions. The acquisition enhances Credo Technology’s vertically integrated AI connectivity stack and is expected to be a significant growth driver in fiscal 2027, supported by increasing hyperscale AI adoption.
