Valuation Assessment
| characteristic | ANET (based on $170) | ANET ($150 after hours) | Sector average |
|---|---|---|---|
| Trailing P/E | 62.1x | 54.8x | ~25x |
| Forward P/E | 39.4x | 34.7x | ~22x |

Growth Outlook
Historical growth rate
The 3-year sales CAGR (2022–2025) is approximately 381 TP3T, recording the fastest growth rate in the industry.
The recent fourth-quarter YoY sales growth rate is actually accelerating, with Q4 2025 at +28.91 TP3T and Q1 2026 at +35.11 TP3T.
Key Growth Drivers
- Explosion in Demand for AI Networking: Demand for 100G/400G/800G Ethernet switches is surging due to increased AI infrastructure investment by mega-cloud companies such as Microsoft, Meta, Google, and Amazon.
- AI Revenue Target Doubled: 2026 AI Revenue Target: $3.5B (Increase from previous year's $1.5B to 133%)
- Campus Network Expansion: Accelerating entry into the enterprise campus market following data centers
- Increased share of software/services: Margin improvement expected due to increased recurring subscription revenue
Calculation of expected growth rate
Historical growth (381 TP3T) × 0.4 + Analyst estimate (281 TP3T) × 0.4 + Industry growth (17.61 TP3T) × 0.2 = approx. 29.9% Expected growth rate
The 2026 annual revenue consensus is $11.5B (guidance raised) and YoY +27.7%, and the FY2026 EPS consensus is $4.32.

Price Forecast (1-Year Target Price)
Current Reference Price: $150.15 (After-hours trading price on May 6, 2026, reflecting Q1 earnings)
| scenario | premise | Target price | Rate of return |
|---|---|---|---|
| Basic (50%) | FY2026 EPS $4.32 × P/E 40x | $172.8 | +15.1% |
| Bullish (25%) | AI demand exceeds supply, EPS $4.70 × 45x | $207.4 | +38.2% |
| Weakness (25%) | Economic slowdown, EPS $4.00 × 35x | $138.2 | -7.9% |
Expected Rate of Return = ($172.8×0.5 + $207.4×0.25 + $138.2×0.25 – $150.15) / $150.15 = +15.1%
The analyst consensus (25 analysts) suggests a Strong Buy, with an average target price of 181.94, a high of 220.0, and a low of 161.0.
Recent Developments
Q1 2026 Earnings Surprise (2026.05.05): Both revenue and EPS exceeded consensus, and annual guidance was raised to 11.5 billion. However, the stock price plummeted -141 in after-hours trading.
“With the typical Wall Street reaction that "it met high expectations but failed to meet even higher ones," this appears to be a short-term correction rather than a deterioration in Arista's fundamentals.
AI Revenue Target Raised by More Than Double: The $3.5B AI sales target is an important signal confirming the strong sustainability of demand for AI infrastructure.
Adjustment after approaching 52-week high: Prior to the earnings announcement, it traded near 179.8 (52-week high), up +901 TP3T from the beginning of the year, and has now entered a healthy correction phase.
Microsoft and Meta Continue Investment in AI: Key customers' capital expenditure plans for 2026–2027 are expected to provide continued benefits to Arista.

Risk Factors
- Valuation Burden: Forward P/E remains at 34–35x even after the sharp after-hours decline — there is a high risk of multiple compression if growth slows.
- NVIDIA InfiniBand Competition: There is a continuous need to prove the competitiveness of Ethernet against NVIDIA InfiniBand in AI cluster networking.
- Customer Concentration Risk: Due to high dependence on top cloud customers (Microsoft, Meta, etc.), it may be vulnerable to changes in the client's investment cycle.
- Geopolitical and Supply Chain Risks: Uncertainty regarding the semiconductor supply chain due to the U.S.-China trade dispute remains.
- Overvaluation Adjustment Risk: After rising +901 TP3T from the beginning of the year, the possibility of a further short-term correction cannot be ruled out.
Investment Recommendation
| item | detail |
|---|---|
| Investment opinion | ✅ Buy |
| Level of certainty | Medium-High |
| 12-month target price | $172.8 (Basic Scenario) |
| Investment period | 12 months |

Arista Networks is a key beneficiary of the AI infrastructure investment cycle.
Q1 2026 earnings surprise and the upward revision of the annual guidance to 11.5B (1TP/4T) confirmed fundamental momentum.
The sharp after-hours decline of -141 TP3T following the earnings announcement is short-term volatility due to high valuations, not a deterioration in the company's fundamentals.
As long as the structure of sustained growth in AI networking demand continues into 2026–2027, the current correction phase offers attractive entry opportunities for mid-to-long-term investors.
