Business Snapshot
Arista Networks designs and sells high‑performance networking switches, routers, and software for data centers, cloud computing, and high‑frequency trading environments. The company competes with Cisco, Juniper, and white‑box vendors, and benefits from the secular shift toward 400G/800G Ethernet and AI cluster networking. The revenue model is largely hardware‑driven but includes recurring software subscriptions (EOS, CloudVision). No analyst targets or guidance are available in this data set.
Financial Trends (4‑Period Trajectory)
| Metric | Q2 2025 (Jun 30) | Q3 2025 (Sep 30) | FY 2025 (Dec 31) | Q1 2026 (Mar 31) | Δ Q1’26 vs Q3’25 |
|---|---|---|---|---|---|
| Revenue ($M) | 2,204.8 | 2,308.3 | 9,005.7 | 2,709.0 | +17.4% (QoQ) |
| Gross Margin | 65.25% | 64.56% | 64.06% | 61.90% | −264 bp |
| Operating Margin | 44.73% | 42.38% | 42.82% | 42.74% | +36 bp |
| Net Margin | 40.31% | 36.95% | 38.99% | 37.76% | +81 bp |
| EPS (Diluted) | $0.70 | $0.67 | $2.75 | $0.80 | +19.4% QoQ |
Revenue accelerated sequentially: Q2 2025 $2.20B → Q3 2025 $2.31B → Q1 2026 $2.71B. The annual FY 2025 figure of $9.01B implies Q4 2025 alone was ~$2.39B (inferred), consistent with a rising trend.
Margins have compressed from the year‑ago peak:
- Gross margin fell from 65.25% (Q2 2025) to 61.90% (Q1 2026), a decline of ~335 bp. This suggests product mix shift toward lower‑margin hardware or pricing pressure.
- Operating margin dipped from 44.73% to 42.74% but has stabilized in the last two quarters.
- Net margin fell from 40.31% to 37.76%, also showing a mild recovery from Q3’s 36.95%.
Cash Flow & FCF
Note: Cash flow line items for 2025-12-31 (10‑K) are annual; the 2025-09-30 and 2025-06-30 figures appear to be YTD cumulative. Below quarterly estimates are derived.
| Quarter | Operating CF (Estimated) | CapEx | Free Cash Flow |
|---|---|---|---|
| Q2 2025 (Jun) | $1,842M (quarter reported) | $52.4M | ~$1,790M |
| Q3 2025 (Sep) | ~$1,268M (cum. $3,110M – $1,842M) | $82.5M | ~$1,185M |
| Q4 2025 (Dec) | ~$1,262M (FY $4,372M – $3,110M) | N/A | N/A |
| Q1 2026 (Mar) | $1,694M (quarter reported) | $54.5M | $1,639M |
Operating cash flow weakened in Q3/Q4 2025 but rebounded sharply in Q1 2026 to $1.69B, the highest quarterly level in the dataset. FCF followed a similar pattern, reaching $1.64B in Q1 2026.
Balance Sheet Strength (all figures from end‑of‑quarter)
| Item | Jun 2025 | Sep 2025 | Dec 2025 | Mar 2026 | Δ latest vs 4Q ago |
|---|---|---|---|---|---|
| Total Assets ($B) | 16.53 | 18.05 | 19.45 | 21.66 | +31.0% |
| Cash & Equiv. ($B) | 2.23 | 2.33 | 1.96 | 2.79 | +25.1% |
| Working Capital ($B) | 9.45 | 10.52 | 11.01 | 12.00 | +27.0% |
| Current Ratio | 3.33x | 3.25x | 3.05x | 2.83x | declining |
| Debt / Equity | — | — | — | — | zero debt |
The balance sheet is fortress‑quality with no debt, growing cash, and rapidly expanding working capital. The current ratio has declined from 3.33x to 2.83x, but this is driven by faster growth in current liabilities (likely deferred revenue and payables) – a sign of scaling operations, not distress.
Financial Health (Latest Period – Q1 2026)
- Revenue growth is accelerating: Q1 2026 produced the highest quarterly revenue in the dataset, and the sequential increase (+$401M or 17%) is the largest on record. This points to strong demand for 400G/800G switching and AI networking.
- Margins are under pressure. Gross margin fell to 61.9%, the lowest in four periods. If this trend persists, it could signal a structural shift toward lower‑margin product categories (e.g., white‑box competition or high‑volume custom builds for hyperscalers).
- Cash generation remains elite. Operating cash flow of $1.69B in a single quarter, even with lower margins, demonstrates pricing power and working capital efficiency. FCF yield on current market cap (~$218B) is about 3.0% annualized – not cheap, but sustainable.
- Balance sheet buffer is growing. Total assets up 31% from June 2025, driven by cash + receivables + inventory. Inventory net grew only moderately ($2.06B → $2.38B), suggesting no forced build‑up.
- No debt, no financing reliance. Share repurchase activity in FY 2025 (financing cash outflow of –$1.6B) shows management is returning capital, but the Q1 2026 financing line is $0 – likely a pause.
Overall: Revenue and cash flow are inflecting upward. Margin compression is a yellow flag but may normalize as scale improves. The company is highly profitable with a pristine balance sheet.
Insider Activity
Sentiment (70‑day window): Neutral (–10)
Net Dollar Flow: –$236,148,354 (Buys $977k, Sells $237.1M)
| Insider | Role | Action | Noteworthy |
|---|---|---|---|
| Jayshree Ullal | CEO | Sells ~$178M across multiple trades (Apr 13–22) | Sold at $150–$178; largest dollar amount. |
| Kenneth Duda | CFO | Buys $488k (option exercise at $15.26) and sells ~$8.3M at $161–$165 | Exercise/conversion then immediate profit‑taking. |
| Chantelle Breithaupt | Director | Sells $1.38M | One‑time sale. |
| Charles Giancarlo | Director | Sells $1.40M | Multiple trades May 1. |
| Yvonne Wassenaar | Director | Sells ~$214k | Small sell. |
Interpretation: Extreme sell‑side activity by the CEO and other insiders. The only buy was an option exercise by the CFO, immediately followed by selling the same shares at market. This is a textbook bearish insider signal. Insiders are monetizing at a time when the stock has been in a strong uptrend. While stock‑based compensation and pre‑arranged 10b5‑1 plans can explain some sales, the scale and concentration (CEO alone $178M) suggest a lack of confidence at current levels, or at least a desire to diversify.
Caution: Insider selling does not always precede a decline, but when the CEO is the primary seller at elevated prices (stock was ~$170s in April), it warrants attention.
Multi‑Timeframe Technical Context
No candle, indicator, or price‑action data were provided for this analysis. This section cannot be completed with the available information. Traders should overlay their own short‑term charts (1m, 5m, 1D) to identify support/resistance and momentum.
Bull / Bear Cases
Short‑Term (hours to days)
| Bull Case | Bear Case |
|---|---|
| Strong Q1 2026 revenue beat (relative to prior quarters) may attract momentum buyers. Cash flow surge suggests no cash‑flow issues. | Insider selling tsunami – CEO alone sold ~$178M in the last month. Overhang could cap any rally. |
| Gross margin stabilized sequentially (61.9% vs 61.5%? Actually had been 64.6% → 61.9% is a drop; not stable). | Margins continue to compress; any negative headline on pricing could drive a rapid selloff. |
| No debt, massive cash pile – safe haven in a macro risk‑off. | Technical data unavailable; if the stock broke below key moving averages, short‑term bears could pile on. |
Long‑Term (weeks to months)
| Bull Case | Bear Case |
|---|---|
| Revenue acceleration tied to AI networking (Arista’s 7060X and 7800R3 are key for AI backbones). | Gross margin trending down – if it falls below 60%, valuation (P/E ~98x on trailing EPS? Actually EPS TTM: Q1 2026 $0.80, FY 2025 $2.75, Q3 2025 $0.67, Q2 2025 $0.71 = $4.93 TTM. At $137, P/E ~27.8x – not extreme. But on forward basis likely higher.) |
| Strong cash generation allows continued buybacks and M&A optionality. | Competition from Cisco, NVIDIA (Spectrum-X), and white‑box vendors could erode market share. |
| Zero debt in a rising rate environment is a structural advantage. | Insider selling may indicate that management sees the stock as fully valued. |
| Working capital growth supports capacity for further expansion. | Growth rates may decelerate as AI capital expenditure cycles mature. |
Summary of Key Tension: The bull case rests on a re‑accelerating top line and pristine finances. The bear case relies on margin erosion and the thunderous sell signal from the CEO.
Key Levels & Triggers
(Since technical data is absent, focus on fundamental triggers)
- Volume: Watch for heavy insider‑sale execution dates (Apr 13–22, May 1). Unusual volume on those dates may have already caused absorption.
- Earnings Catalyst: Next 10‑Q (Q2 2026) likely due mid‑August 2026. A surprise on gross margin or revenue guidance will drive the next major move.
- Key Fundamental Trigger: Any announcement regarding a major AI data center win (e.g., hyperscaler deal) could reverse bearish insider sentiment on market share gains. Conversely, a pricing/margin warning would amplify the insider sell signal.
- Support: Without chart levels, use the latest insider sell range – $150–$178. A breakdown below $150 (where CEO sold heavily on Apr 13) would be technically and sentimentally negative.
- Resistance: The area above $178 (CEO’s highest sold price on Apr 22) is potential resistance if the stock recovers.
