Arista Networks increases purchase commitments amid multi-year memory supply shortage
Tuesday, March 3, 2026 at 06:00 PM
Arista Networks' CEO reported ongoing and worsening shortages in the memory supply chain, noting that the company is increasing purchase commitments to mitigate long-term supply constraints expected to persist for several years due to high demand in AI and automotive sectors.
Context
Arista Networks has accelerated its purchase commitments to $6.8 billion to combat a memory shortage that CEO Jayshree Ullal describes as "horrendous" and likely to last multiple years. Terming memory "the new gold" for the AI and automotive sectors, the company is aggressively securing supply to support its transition to 800G and 1.6T Ethernet ports. This strategic stockpiling, up from $4.8 billion in the previous quarter, utilizes the company's $10 billion cash reserve to bypass volatile spot markets and ensure production capacity for hyperscale customers.
The supply pressure comes as Arista Networks raises its 2026 revenue guidance to $11.25 billion, following a record $9 billion performance in 2025. While the firm has absorbed costs to sustain non-GAAP gross margins in the 62% to 64% range, management warned that selective price increases may be necessary for memory-heavy products throughout 2026. With AI-specific networking revenue projected to double to $3.25 billion this year, securing long-term inventory has become a core operational priority to maintain its lead in the AI infrastructure supercycle.
