SANTA CLARA, California, May 5, 2026, 14:02 (PDT)
- Arista Networks posted a 35.1% jump in first-quarter revenue, reaching $2.709 billion, as appetite for AI and cloud networking equipment remained strong.
- Adjusted earnings landed at 87 cents per share, topping the FactSet consensus of 81 cents. For the second quarter, the company is looking for sales of about $2.8 billion—right on top of Wall Street’s $2.78 billion estimate.
- Shares edged lower in late trading, with investors apparently looking for a heftier boost after ANET stock’s strong rally this year.
Shares of Arista Networks slipped after hours Tuesday. The data-center networking specialist topped estimates for its first-quarter profit and revenue but offered a second-quarter outlook that just slightly surpassed what analysts had penciled in.
Traders track Arista closely now, as it’s seen as a gauge for AI-driven data-center budgets. Shares are already up roughly 30% for 2026 after Tuesday’s close, so expectations are high and a standard earnings beat doesn’t offer much upside.
Arista builds switches and software to shuttle data among servers deep inside sprawling cloud and AI data centers. The company’s riding a surging market, though the competition has tightened—Nvidia, Cisco, and Hewlett Packard Enterprise’s Juniper arm are all vying for business as clients scale up their AI clusters.
Arista Networks reported quarterly revenue of $2.709 billion for the period ending March 31, up from $2.005 billion the previous year. GAAP earnings hit 80 cents per share, up from 64 cents, while non-GAAP earnings—which strip out items like stock-based pay—came in at 87 cents, compared with 66 cents a year ago.
FactSet’s analyst consensus had pegged adjusted earnings at 81 cents per share on $2.62 billion in revenue, Dow Jones reported. Arista’s own forecast called for roughly $2.6 billion in revenue.
The June quarter guidance stood out. Arista is looking for around $2.8 billion in revenue, adjusted EPS at roughly 88 cents, and a non-GAAP operating margin ranging between 46% and 47%. StreetInsider pegged consensus at $2.78 billion and 86 cents a share on the bottom line.
The stock ended the session off 1.4% at $170.22, then tracked down another 5.8% after hours to $160.35 just after the news hit, according to MarketScreener data.
Margins remain a key concern. Arista’s GAAP gross margin dropped to 61.9%, down from 63.7% a year ago, while non-GAAP gross margin slipped to 62.4% from 64.1%. Non-GAAP operating margin, however, stayed put at 47.8%.
“Off to a strong start,” Chief Executive Jayshree Ullal said, adding that Arista is “uniquely positioned” in secure cloud and AI networking. CFO Chantelle Breithaupt cited “disciplined execution” but flagged that macro and supply-chain conditions are still “dynamic.” Arista Networks
The company flagged new products targeting AI data centers. Arista claims its XPO high-density liquid-cooled pluggable optics can reduce networking racks by as much as 75%, trimming floor space needs up to 44% compared to standard pluggable optics. The 7800-based AI spine, meanwhile, is designed for heavy AI traffic.
The report came on the heels of renewed buzz from retail investors. On “Mad Money,” CNBC’s Jim Cramer told viewers he “would buy Arista Networks,” calling it a key player that helps “machines in the data center talk to each other.” Insider Monkey
Still, the risks aren’t far off. Arista flagged potential trouble from tariffs, parts shortages, heavy dependence on a major merchant silicon supplier, concentrated customers, and intensifying competition. Rivals—including Nvidia, Cisco, and HPE’s Juniper unit—are all vying for the same AI networking turf.
The focus now shifts to whether management can prove AI networking demand continues to outpace expectations. According to IBD, Arista stuck with its 2026 AI networking revenue target of $2.75 billion to $3.25 billion—that’s the range investors are watching to gauge what upside might remain for the trade.
