CIEN•Arista Networks has raised its 2026 revenue forecast to $11.5 billion, driven by expected $3.5 billion in AI infrastructure sales, doubling AI revenues year-over-year. However, supply constraints could last one to two years, generating $6.2 billion in deferred revenue and pressuring gross margins.
Arista Networks has experienced record demand for its high-speed networking hardware, driven by hyperscale customers building AI infrastructure. The company raised its full-year 2026 revenue target to $11.5 billion, with AI-related sales expected to reach $3.5 billion, reflecting a doubling of AI revenue compared to the prior year.
Management warned that component shortages—from wafers to optics—are creating a one- to two-year supply bottleneck. Arista is incurring higher procurement costs to secure limited capacity, which is expected to compress gross margins as the company fulfills demand at elevated input expenses.
The backlog of unrecognized revenue has grown to $6.2 billion as deployed AI networking projects await formal customer sign-off before bookings can be recognized. This deferred revenue balance represents products shipped and installed but pending contractual acceptance over six to eight quarters.
Arista faces the challenge of converting its massive backlog into recognized sales before customers seek alternative suppliers. Efficient deployment and faster customer approvals will be critical to sustaining growth momentum and avoiding market share erosion.
