Arista Networks: A Bargain, Perhaps?

by

Arista Networks (ANET +0.70%). The name itself lacks a certain… resonance. It doesn’t quite conjure images of titans of industry, does it? More like a particularly efficient plumbing supply company. Yet, beneath this unassuming exterior, a curious phenomenon is unfolding. Wall Street, that fickle mistress, whispers of a bargain. A bargain, mind you, in the realm of artificial intelligence, a field currently experiencing more hype than a Moscow theatrical premiere. A 23.6% upside potential, they claim, as of February 13th. One almost expects Behemoth to stroll in and demand a cut.

The core of this… intrigue lies in Arista’s rather vital, if unglamorous, role. They provide the Ethernet infrastructure – the digital capillaries, if you will – that connect the servers and AI accelerators within these modern data cathedrals. It’s the scaffolding upon which the digital miracles are built. And, naturally, everyone fixates on the miracles, conveniently forgetting the scaffolding. A predictable human failing.

A Revenue Visibility That Borders on the Ominous

The transition is happening, slowly, inexorably. Arista’s solutions, based on that most practical of technologies, Ethernet, are moving beyond the experimental stage. No longer merely toys for the engineers, they are being deployed at scale. As these AI data centers swell with complexity, the bottleneck isn’t simply computing power, it’s the ability to move data. A digital traffic jam, if you will. And Arista, it seems, is selling the traffic cops. The company now anticipates AI networking revenues of $3.25 billion by 2026. A tidy sum, though one can’t help but wonder what Faustian bargains were struck along the way.

Several large customers, already knee-deep in GPU deployments, are utilizing Ethernet-based architectures. Others are preparing to join them, though, as always, they lag. The initial rush to acquire the glittering new toys – the GPUs and accelerators – leaves the necessary infrastructure trailing behind. A rather pedestrian observation, but one that rarely penetrates the fog of technological fervor. They build the temple, then wonder where to put the altar. Arista stands to benefit from this predictable oversight.

Beyond the AI frenzy, Arista is cautiously expanding into campus, branch, and routing markets. A sensible diversification, like a chess master anticipating his opponent’s next move. They anticipate $1.25 billion in revenues from these ventures by 2026. Campus and networking now account for 18% of their total revenues. A solid foundation, though hardly the stuff of legends.

Management now estimates their total addressable market to exceed $100 billion. A figure that, frankly, feels suspiciously… optimistic. But in this age of boundless ambition, who dares question the pronouncements of those in power? Arista’s updated revenue growth guidance for 2026 is 25%, up from a prior estimate of 20%. A modest improvement, perhaps, but a welcome one nonetheless.

Profitable Growth, A Rarity These Days

The most curious aspect of Arista’s trajectory is its profitability. In a world obsessed with growth at any cost, they are actually… making money. Operating at gross margins in the low-to-mid-60% range, with expected operating margins of 46% in 2026. A feat that borders on the miraculous. They’ve managed to navigate the rising costs of supply chains, memory, and advanced networking chips without sacrificing their bottom line. A testament to shrewd management, or perhaps a pact with some unseen entity. One can’t be certain.

Beyond the hardware, their software and subscription business is strengthening their competitive moat. EOS and CloudVision, their network software and services, automate operations and provide deep visibility into complex traffic patterns. They allow customers to understand the chaos, to impose order upon the digital maelstrom. A valuable service, particularly in an age of increasing complexity. These capabilities are tightly integrated into customer networks, building a loyal, if somewhat captive, customer base.

Arista has served over 10,000 cumulative customers, with CloudVision deployed across roughly 3,000 over the past decade. Software is a high-margin revenue stream, improving the revenue mix. A sensible strategy, like a seasoned gambler hedging his bets.

They exited fiscal 2025 with a cash balance of $10.7 billion and negligible debt. A fortress of financial strength, allowing them to invest in future growth initiatives. A comforting sight, like a well-stocked pantry in times of uncertainty.

Therefore, given the evidence, Arista Networks appears well-positioned to surprise investors in the coming years. Though, one should always remember, the most carefully laid plans often succumb to the whims of fate. And in the realm of technology, fate is a particularly capricious mistress.
