MRVL's Margin Pressure Mounts as AI Revenues Rise: Is it Sustainable?

Read MoreHide Full Article

Key Takeaways

  • MRVL's revenues are rising due to strong demand for custom AI XPUs and high bandwidth memory chips.
  • Higher manufacturing costs in AI silicon are driving a continued decline in MRVL's gross margin.
  • MRVL faces stiff competition from AVGO and AMD in custom silicon solutions and AI accelerators.

Marvell Technology’s (MRVL - Free Report) top line is growing on the back of custom AI silicon chips that are experiencing massive traction among hyperscalers. However, Marvell Technology’s gross margin has been moving inconsistently for the past several quarters, with a long-term declining trend.

MRVL’s robust top-line growth is coming from the massive traction in its custom AI XPUs, electro-optics solutions and custom high bandwidth memory chips, which enable longer reach scale-up fabric connections for custom AI servers and improve bandwidth. The Co-Packaged Optics improves performance by increasing XPU density.

However, Marvell Technology’s custom AI silicon, including XPUs, which are driving its revenue growth, comes with higher costs associated with manufacturing these chips. The margin in the AI-focused custom silicon semiconductor business is fundamentally lower, further affecting MRVL’s total gross margin.

Marvell’s non-GAAP gross margin has declined 260 basis points from the year-ago quarter and 30 basis points sequentially to 59.8% in the first quarter of fiscal 2026. For the second quarter of fiscal 2026, MRVL has projected a non-GAAP gross margin range of 59% to 60%, which is lower than the second quarter of fiscal 2025’s gross margin of 61.9%.

Nevertheless, as MRVL’s other business segments are on the path of recovery so this margin pressure might ease out in the long run.

How Competitors Fare Against MRVL

The contraction in gross margin is not the only challenge faced by MRVL stock at present. The company also faces massive competitive pressure from Broadcom (AVGO - Free Report) and Advanced Micro Devices (AMD - Free Report) in the custom silicon solutions space.

Broadcom’s advanced 3.5D XDSiP packaging platform is specifically designed to enhance the performance and efficiency of custom AI XPUs. Broadcom’s Semiconductor segment, which accounts for its custom silicon solutions, grew 11% year over year in the first quarter of fiscal 2025.

Advanced Micro Devices’ custom silicon solutions and AI accelerators, like Instinct Accelerators, power numerous data centers. Advanced Micro Devices’ reconfigurable Alveo Adaptable Accelerator Cards are used to speed up compute-intensive applications in data centers.
