Networking product gross margin measures product gross profit as a percentage of product revenue using Arista's disclosed product revenue and cost of revenue.

Arista reported $7.577 billion of product revenue and $2.979 billion of product cost of revenue for 2025.

Grizzly Bulls calculates an approximate product gross margin of 60.7%

The calculation is:

($7.577B - $2.979B) / $7.577B = 60.7%

That implies roughly $4.598 billion of product gross profit from the rounded disclosed values.

Service margin was about 21.2 points higher

Arista's derived service gross margin was about 81.9%.

The roughly 21.2-percentage-point spread shows why changes in product-versus-service mix can affect blended gross margin even when both revenue streams grow.

This is a calculated issuer-specific margin

Product mix, customer pricing, merchant silicon, freight, tariffs, and inventory charges can all move the result.

Use Networking Service Gross Margin for the adjacent economics rather than treating 60.7% as a standardized peer margin.

Where this concept fits

Unit economics and concentrationCurrent relationship
Product and service gross margins show the different cost structures of hardware-oriented shipments and support delivery. Non-Americas mix and top-two customer concentration show where revenue is generated and how dependent results are on a small number of large customers whose deployment timing and pricing can affect reported margins.

Platform mix and revenue composition
Core, Cognitive Adjacencies, and Software and Services describe Arista's product-category mix, while product and service revenue use the financial-statement classification. Product and service revenue mix therefore answer a different question from product-category mix and should be analyzed separately.

Deferred revenue and supply-chain commitments
Deferred revenue and its opening-balance recognition rate connect product acceptance and support contracts to future recognition, while the two-year future-revenue mix adds timing. Inventory write-downs and purchase commitments show the operating risk created when long-lead sourcing and product transitions outrun realized customer demand.
