NEW YORK, August 5, 2026, 09:12 EDT — U.S. stocks were active ahead of the open.
- Arista shares climbed 10.3% to $210.90 just ahead of the market open.
- The company’s third-quarter revenue projection of $3.3 billion exceeded LSEG expectations by roughly 12%.
- Management increased its revenue forecast for 2026 to $12.6 billion, indicating a 40% rise.
Arista stock rose 10.3% to $210.90 as of 8:59 a.m. ET, after the company issued a quarterly outlook that surpassed Wall Street’s high expectations.
The investor message extended beyond another earnings win tied to AI. Management lifted its 2026 outlook by $1.1 billion compared to the projection made in May. The company anticipates expansion across key data-center, campus, routing, and AI-related products.
Revenue for the second quarter climbed to $3.036 billion, marking a 37.7% increase compared with the previous year. Adjusted earnings were up 39.7% at $1.02 per share.
| Metric | Q2 2026 actual | Wall Street estimate | Beat | Year-on-year |
|---|---|---|---|---|
| Revenue | $3.036 billion | $2.82 billion | 7.6% | 37.7% |
| Adjusted EPS | $1.02 | $0.88 | 15.9% | 39.7% |
| Non-GAAP operating margin | 49.9% | — | — | increase of 110 basis points |
| Non-GAAP gross margin | 63.4% | — | — | decline of 220 basis points |
Arista’s reported results and LSEG consensus forecasts are the basis for beat calculations.
Operating leverage stayed exceptionally robust. The adjusted operating margin was 49.9%, maintaining strength even as gross margin declined due to shifts in customer and product mix.
Arista increased its third-quarter outlook, now expecting $3.3 billion in revenue and adjusted EPS in the range of $1.06 to $1.08.
| Metric | Arista forecast | Comparison | Implied difference |
|---|---|---|---|
| Revenue | About $3.30 billion | LSEG: $2.94 billion | 12.2% above consensus |
| Adjusted EPS | $1.06-$1.08 | LSEG: $0.91 | 17.6% higher than consensus at midpoint |
| Revenue growth | $3.30 billion | Q2: $3.036 billion | 8.7% higher quarter-on-quarter |
| Revenue growth | $3.30 billion | Q3 2025: $2.308 billion | Near 43.0% higher year-over-year |
| Non-GAAP operating margin | 48%-49% | Q2: 49.9% | Down 140 basis points at midpoint |
Cited company data and figures from LSEG are used to determine growth rates and midpoint comparisons.
The revenue outlook signals another significant sequential increase. Margin forecasts permit slight normalization, reflecting rising shipments and supply expenses.
The key focus for investors is the makeup of that expansion. CEO Jayshree Ullal referred to the extra demand as covering Arista’s “core Arista product line.” MarketBeat
Simon Leopold, an analyst at Raymond James Financial NYSE:RJF, arrived at the same assessment. “Most of the incremental forecast stems from Arista’s core/general purpose products,” he wrote. Investors.com
| 2026 outlook component | Management figure | Share of $12.6 billion guide |
|---|---|---|
| Company-wide revenue | Approximately $12.60 billion | 100% |
| AI fabrics minimum revenue | At minimum $3.50 billion | At minimum 27.8% |
| Campus minimum revenue | At minimum $1.25 billion | At minimum 9.9% |
| Combined reported minimums | At least $4.75 billion | At least 37.7% |
| Other revenue, calculated maximum | No more than $7.85 billion | No more than 62.3% |
The residual is calculated by subtraction and does not reflect a segment forecast provided by the company. Arista’s stated AI and campus numbers represent minimum targets.
The calculation underpins a wider demand thesis. Over 60% of projected revenue is likely to still originate from key data-center, routing, services and additional sales.
Visibility of demand increased as well. Deferred revenue climbed to approximately $6.9 billion, and purchase commitments totaled $9.7 billion. These commitments represent about 3.2 times the company’s quarterly revenue.
Wall Street started adjusting targets ahead of the opening bell. Three optimistic updates have moved Arista’s latest valuation range to between $240 and $280.
| Firm and analyst | Recommendation | Previous target | New target | Upside from $210.90 |
|---|---|---|---|---|
| Rosenblatt, Mike Genovese | Buy | $210 | $280 | 32.8% |
| Needham, Ryan Koontz | Buy | $200 | $260 | 23.3% |
| Bank of America NYSE:BAC, Tal Liani | Buy | $200 | $240 | 13.8% |
The implied upside is calculated based on the $210.90 premarket price observed at 8:59 a.m. ET.
The overall published consensus continued to indicate 24 buy recommendations and a single hold. The average price target of $201.25 was still under the premarket level. This difference is likely due to the updates from Wednesday not being fully factored in yet.
Risks continue to be significant. Purchase obligations are currently approximately 2.7 times higher than they were a year ago. Management anticipates that supply constraints industry-wide will continue through 2028. If demand slows, inventory may accumulate or gross margin may come under additional pressure.
The surge means there is limited space for an average quarter. Investors are now seeking proof that core networking can maintain the accelerated momentum in the second half.
