Down 20% From Highs, Is Arista Networks a Genius Buy or a Trap Before Earnings?
Arista Networks heads into earnings having posted its first $3 billion quarter, yet the stock has shed nearly 10% in a month while trading at a premium multiple that left no margin for error last time around.
Arista Networks (NYSE:ANET | ANET Price Prediction) is expected to report third-quarter results on November 3 after the close. Shares have fallen 9.8% over the past month. This report will show whether AI networking demand still supports a premium valuation.
A Record Quarter, Then a Pullback
Last quarter, Arista posted its first $3 billion quarter. Revenue of $3.04 billion grew 37.7% year over year and beat the $2.83 billion estimate. Non-GAAP EPS of $1.02 exceeded the $0.89 consensus, extending the EPS beat run to 6 consecutive quarters.
Fiscal 2026 revenue guidance was raised to $12.6 billion, or 40% growth, up from $11.5 billion in May. Deferred revenue rose to $6.9 billion from $6.2 billion, and purchase commitments reached $9.7 billion.
The stock remains up 42.18% year to date at $186.30, though it traded at $206.55 a month ago. For Q3, management guided to about $3.3 billion in revenue, roughly 63% gross margin and EPS of $1.06 to $1.08.
Consensus Calls for Growth Above 40%
| Metric | Consensus | Prior-Year Actual | Implied YoY Growth |
|---|---|---|---|
| Q3 2026 EPS | $1.0788 | $0.75 | 43.84% |
| Q3 2026 Revenue | $3.33 billion | $2.31 billion | 44.44% |
| FY 2026 EPS | $4.1168 | $2.98 | 38.15% |
| FY 2026 Revenue | $12.68 billion | $9.01 billion | 40.75% |
Gross Margin and Another Guidance Raise Will Set the Tone
Gross margin is the first number to watch. It dropped to 63.4% in Q2 from 65.6% a year earlier on customer mix, with tariff refunds adding 20 to 30 basis points. CEO Jayshree Ullal said price increases will help “only towards the end of the year or more like next year” as memory and silicon costs rise.
Guidance comes next. Ullal said “all numbers are going up,” and fourth-quarter revenue consensus already stands near $3.6 billion. Analysts raised fiscal 2026 EPS estimates to $4.1168 from $3.6363 over 90 days, so a simple confirmation could look light.
AI fabric updates are another area to watch. Arista counts more than 100 cumulative Etherlink customers, targets at least $3.5 billion in AI fabrics revenue this year, and expects 1.6T switches to enter trials in the second half of 2026 before production in 2027.
Concentration and supply round out my list. Management expects 1, maybe 2 10% customers, anchored by Microsoft (NASDAQ:MSFT) and Meta Platforms (NASDAQ:META), and warned of extended component shortage: “I don’t think we get out of it as an industry until 2028.”
A Premium Multiple Leaves Little Room for Error
At $186.30, Arista trades around 45x fiscal 2026 consensus EPS. Beats alone have not guaranteed rallies. Shares dropped 13.61% after Q1 2026 results despite a 7.73% surprise.
Whether this pullback proves temporary depends on stable margins and a credible path above $12.6 billion. If management delivers both, the recent selloff may look like a reset heading into 2027.
