What Happened?
Arista Networks stock jumped about 6% on Wednesday to $210 per share, bringing shares back near their 52-week high of about $215 as investors continued to respond to strong AI networking demand, higher 2026 guidance, and a wave of analyst target increases. The broader opportunity is getting more competitive, with Cisco and Nvidia both targeting AI data-center networking spending. Cisco, for example, recorded $9.3 billion of hyperscaler AI infrastructure orders in fiscal 2026, including $4 billion in its latest quarter.
Arista stock rose because its Q2 results showed that surging AI and cloud networking demand is translating into faster growth, while management substantially raised expectations for the rest of 2026. Revenue reached a record $3.0357 billion, up 37.7% year over year, while non-GAAP EPS increased 39.7% to $1.02 and non-GAAP operating margin reached 49.9%. Arista also lifted its 2026 revenue outlook to approximately $12.6 billion, or around 40% growth, which is $1.1 billion above the $11.5 billion projection management gave in May.
In its latest earnings call, management provided more evidence that the acceleration has room to continue, with Etherlink AI fabric adoption exceeding 100 cumulative customers and purchase commitments reaching $9.7 billion as Arista secures components for future deployments. AI fabrics are high-speed Ethernet networks that connect large numbers of AI processors so they can exchange data efficiently as AI clusters grow. CEO Jayshree Ullal said “We are now projecting 40% annual growth,” while management set 2026 goals of at least $3.5 billion in AI fabrics revenue and $1.25 billion in campus revenue, and guided Q3 revenue to approximately $3.3 billion, with a 48% to 49% operating margin and diluted EPS of $1.06 to $1.08.
Analyst actions reinforced the earnings-driven advance. Barclays raised its price target to $289 from $195, Rosenblatt to $280 from $210, Needham to $260 from $200, UBS to $259 from $187, Wells Fargo to $255 from $200, JPMorgan to $250 from $220, Evercore ISI to $250 from $200, and KeyBanc to $250 from $200. The size and breadth of those revisions suggest Wall Street increasingly views Arista as a beneficiary of a longer AI networking investment cycle rather than a short hardware refresh, while improving supply availability gives the company more capacity to turn cloud and enterprise demand into revenue.

Is Arista Networks Fairly Valued?
Under valuation assumptions, the stock is modeled using:
- Revenue Growth (CAGR): Around 30%
- Operating Margins: Around 47%
- Exit P/E Multiple: 31x
Arista’s roughly 30% modeled revenue growth has a credible starting point because management now expects approximately $12.6 billion of 2026 revenue, while AI fabrics, traditional data-center networking, campus systems, and routing give the company multiple growth engines rather than leaving the outlook dependent on a single AI product cycle.
Supply execution could determine how quickly that demand becomes reported revenue. Arista increased purchase commitments to $9.7 billion, secured its 2026 memory supply, expanded manufacturing and distribution capacity, and established a liquid-cooling supply chain for increasingly dense AI systems. Management also said industry-wide supply tightness persists, making improved component availability an important part of the stronger second-half outlook.

Profitability is an equally important part of the story. Arista delivered a reported 49.9% non-GAAP operating margin in Q2, while the TIKR EBIT chart shows consensus margins staying around 49% through the forecast period. The valuation model’s roughly 47% operating margin therefore builds in some normalization rather than assuming current profitability expands indefinitely.
Competition remains substantial, but Arista combines rapid growth with unusually high profitability. Cisco’s latest quarter produced $17.25 billion of revenue, up 17.6% year over year, while its fiscal 2026 hyperscaler AI infrastructure orders reached $9.3 billion, confirming that the AI networking opportunity is large enough to attract aggressive competition. Arista’s EOS software and high-performance Ethernet architecture therefore need to keep winning on reliability, scalability, and operating simplicity as Cisco and Nvidia push deeper into large AI data centers.
At around $210 per share, TIKR’s valuation model targets around $243, implying about 16% total upside over roughly 2.4 years, or around a 6% annualized return. That leaves Arista looking close to fairly valued rather than deeply discounted, with stronger returns depending on continued AI fabric adoption, broader enterprise growth, improving supply execution, and the company’s ability to preserve high margins as revenue scales.
