Key Takeaways
- Q1 2026 revenue reached $2.71 billion, representing 35% year-over-year growth and surpassing the $2.61 billion Street estimate
- The company delivered adjusted earnings per share of $0.87, improved from $0.66 in the same period last year
- Shares plummeted nearly 14% in extended trading despite exceeding expectations, driven by margin and annual outlook worries
- Second-quarter projections of $2.8 billion in revenue and $0.88 EPS beat consensus, yet full-year growth guidance of 27.7% fell short of analyst forecasts in the 28–30% range
- Morgan Stanley maintained its Overweight stance, describing ANET as “one of the cleanest ways to own the AI networking cycle”
Arista Networks delivered impressive first-quarter results, yet investors responded with sharp selling pressure. Shares plunged nearly 14% during after-hours trading Tuesday, sliding below $148 after ending the regular session at $170.22, off 1.4%.
The dramatic decline occurred despite the company exceeding both top and bottom-line expectations. First-quarter revenue totaled $2.71 billion, outpacing the consensus estimate of $2.61 billion. Adjusted earnings per share of $0.87 surpassed the prior-year figure of $0.66. Billings growth showed notable acceleration, reaching 54% year-over-year compared to 43% in the previous quarter.
Looking ahead to Q2, the company projected approximately $2.8 billion in revenue alongside adjusted EPS of $0.88 — both figures exceeding analyst predictions. What triggered the selloff?
The culprit was margin pressure. The company forecast an adjusted operating margin between 46% and 47% for the second quarter, declining from Q1’s 47.8% and trailing last year’s Q2 margin of 48.8%. This compression raised red flags among investors.
The more significant headwind emerged from the annual forecast. While Arista lifted its 2026 revenue growth projection to 27.7% from a previous 25% estimate, Morgan Stanley analyst Meta Marshall highlighted that Wall Street had anticipated growth between 28% and 30%, creating a meaningful disconnect that fueled the retreat.
New Product Launches
On the innovation front, Arista unveiled XPO high-density liquid-cooled pluggable optics, engineered specifically for next-generation AI data centers. According to the company, XPO reduces networking rack space requirements by as much as 75% while delivering up to 44% savings in floor space compared to conventional pluggable optics.
The company also rolled out what it describes as a “universal AI spine” utilizing its 7800 platform. This system is architected to support massive AI workloads, incorporating capabilities such as Virtual Output Queuing to eliminate bottlenecks during AI traffic spikes.
Chief Executive Jayshree Ullal highlighted the company’s Net Promoter Score of 89, with 94% of customers providing favorable ratings, as validation of robust operational execution.
Analysts Maintain Optimistic Outlook
Notwithstanding the after-hours plunge, Wall Street sentiment continues to skew positive. Morgan Stanley’s Marshall retained his Overweight recommendation, characterizing Arista as among the most compelling opportunities for capturing AI networking expansion. While acknowledging supply chain headwinds, he noted Arista’s superior track record in navigating such challenges compared to competitors.
Additional research firms preserved Buy or Strong Buy recommendations, with several raising price objectives following the quarterly report.
Analysts at Evercore ISI had identified Arista as a potential winner from Alphabet’s new Virgo Network platform prior to the earnings release, observing that Virgo’s design philosophy aligns seamlessly with Arista’s high-radix, high-bandwidth switching solutions.
Despite Tuesday’s sharp decline, ANET remained elevated nearly 30% for the year-to-date period and had rallied more than 87% over the trailing twelve months entering the earnings announcement.
Marshall’s research note captured the current investment debate succinctly: questions surrounding Arista no longer center on demand strength — instead, the focus has shifted to the company’s ability to procure adequate supply.
