Arista Networks Inc. Common Stock (ANET) fair value

ACCE thesis

Arista Networks sells Ethernet switches and the EOS operating system that runs them, and its data center customers are increasingly buying those boxes to wire together large AI accelerator clusters. The moat is less about the hardware than about EOS and the cloud-scale automation built on it, which lets hyperscalers run one software stack across very large networks and makes switching vendors costly. Revenue growth of 37.7% on a company already at a 45.4% operating margin is unusual at this size, and it is coming from the AI back-end networking build-out rather than a one-off refresh cycle. At a forward P/E of 39.2 against a trailing 58.5, the market is pricing in a sizable earnings ramp, so the question for a deeper look is whether AI networking demand holds up through the next budget cycles of its large cloud customers. Arista is not in any major index, which is worth checking when sizing a position.
