# Arista Networks: Business Model & Revenue Engine



## Direct Answer

Arista Networks reports revenue across 2 product and service lines in its fiscal 2025 Form 10-K. Product is the largest, with $7.6 billion of revenue (84% of the total), followed by Service at $1.4 billion (16%).

## How Does Arista Networks Make Money?

Product supplies 84% of revenue, so Arista Networks's results move mostly with that one business; the others matter more for diversification than for the headline number. Between fiscal 2024 and 2025, Product grew fastest (+28.8%) and Service slowest (+27.7%), so the revenue mix tilts toward Product while that gap lasts.

| Product or service | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| Product | $7.6 billion | $5.9 billion | 84.1% | 28.8% |
| Service | $1.4 billion | $1.1 billion | 15.9% | 27.7% |

## What the Segment Figures Do Not Show

The rows above add up to 100% of Arista Networks's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.

## Where These Numbers Come From

Every figure on this page is a value Arista Networks reported in the segment note and revenue disclosures of its Form 10-K filed February 17, 2026 (accession 0001596532-26-000013), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.

Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
