1. Earnings Preview

Key Takeaway: The setup favors a beat on revenue with consensus sitting at $2.827B vs. guidance of ~$2.8B, but the real debate is whether deferred revenue conversion and gross margin can surprise to the upside — supply-chain headwinds remain the single biggest swing factor.

Heading into Q2 2026, the bar for Arista is calibrated tightly around management's own guidance: consensus revenue of $2.827B sits just ~1% above the $2.8B midpoint guided on May 5, and non-GAAP EPS consensus of $0.883 is essentially in line with the $0.88 guide, leaving limited room for a large headline beat but also a low hurdle for an in-line print. Management's tone on the Q1 call was the most bullish in company history — CEO Jayshree Ullal described demand as "the best I've ever seen in my Arista tenure" — yet simultaneously flagged industry-wide supply shortages across wafers, silicon, CPUs, optics, and memory as a 1-to-2-year phenomenon, creating a supply-constrained ceiling on near-term revenue upside. Estimate revisions since the Q1 print have been remarkably stable: the 2Q26 revenue consensus moved from $2.823B on May 8 to $2.827B today, and FY26 consensus edged from $11.582B to $11.600B, suggesting the Street has largely accepted management's framework and is not pricing in incremental upside. The stock has rallied ~15.6% in the past month and is up ~50% over the past year, trading at ~43.8x NTM P/E — a premium that prices in continued strong execution and leaves the stock vulnerable to any guidance disappointment. The wildcard heading into the print is the trajectory of

deferred revenue: at $6.2B exiting Q1 (up $830M sequentially), any acceleration in customer acceptance and revenue recognition — or conversely, a further build — will be the most watched data point beyond the headline numbers, as it signals whether AI deployments are converting to P&L revenue or continuing to accumulate on the balance sheet.

2. KPIs & Consensus Expectations

Key Takeaway: Consensus is a low bar on revenue (~1% above guidance midpoint at $2.827B) and essentially in-line on EPS ($0.883 vs. $0.88 guide);

gross margin is the bigger swing factor — any upside vs. the 62%–63% guide would be the catalyst for a post-earnings rally, while a miss would pressure the stock despite a revenue beat.

Source: Visible Alpha Consensus and Actuals Data. Pattern: ANET has beaten revenue consensus in each of the last 8 quarters by 1.5%–4.7%, and non-GAAP EPS by 5%–15%; the beat cadence is consistent but the magnitude has compressed as guidance has become more precise — suggesting the Street has learned to calibrate closer to management's own numbers.

3. Guidance & Commentary Evolution

Key Takeaway: No guidance revisions since the May 5 Q1 2026 earnings call — the June 25 rack-scale AI webinar was purely product/technology focused with zero financial updates. Management tone remains

Note: The June 25, 2026 "New Era of Rack-scale AI Fabrics" webinar introduced the 7060 XC seven series 1.6T platform and discussed XPO liquid-cooled optics but contained no financial guidance updates or revisions to any metric above.

Key Takeaway: Guidance has been unchanged since the Q1 2026 earnings call on May 5; no post-earnings 8-K, conference, or investor day has revised the Q2 or FY26 numbers. Management tone remains

Key Takeaway: No guidance revisions since the May 5 Q1 2026 earnings call. Management tone remains

extremely bullish on demand ("best I've ever seen") while cautious on supply — a combination that keeps estimates anchored tightly to guidance with no incremental upside being priced in.

4. Guidance vs. Estimate Revision Tracker

Key Takeaway: Estimates have been remarkably stable since the Q1 print — Q2 revenue consensus moved only +$4M (+0.1%) from the post-earnings baseline, and FY26 revenue moved +$18M (+0.2%), suggesting the Street has fully absorbed management's guidance framework with no incremental upside being priced in.

The near-zero estimate drift since the Q1 print is notable: the Street has essentially locked in management's guidance as the base case with no incremental upside or downside being priced in. This creates a binary setup — any deferred revenue conversion surprise or supply-chain improvement commentary could drive meaningful upward revision, while a gross margin miss or cautious Q3 guide could trigger the reverse.

5. Stock Performance

Key Takeaway: The +50% 12-month gain has been driven almost entirely by

earnings/estimate revisions with minimal multiple expansion (+0.5% NTM EV/EBITDA over 12 months), but the recent +15.6% 1-month surge reflects multiple re-expansion (+6.6%) — suggesting the stock has gotten ahead of fundamentals in the near term and is vulnerable to any guidance disappointment.

Key Takeaway: ANET's +50% 12-month gain is predominantly earnings/estimate-driven with only modest multiple expansion (+0.5% NTM EV/EBITDA over 12 months), but the recent +15.6% 1-month surge reflects multiple re-expansion (+6.6% EV/EBITDA) — suggesting the stock has gotten ahead of fundamentals in the near term.

Sector ETF: IGV (iShares Expanded Tech-Software Sector ETF) is the most appropriate benchmark for ANET given its software-first networking model and premium valuation profile. The 1-month multiple re-expansion (+6.6% EV/EBITDA) is the key risk heading into the print — the stock has priced in a beat and any in-line result with cautious Q3 guidance could compress the multiple back toward the 3-month average of ~35.8x.

6. Material News & Developments

Key Takeaway: The most important development since Q1 earnings is the June 25 launch of the 1.6T 7060 XC seven series platform, which validates Arista's AI networking roadmap and positions the company for the next speed-generation upgrade cycle; the broader AI infrastructure spending acceleration confirmed by hyperscaler capex raises (Amazon to $220B, Alphabet raising guidance) is a strong demand read-through.

7. Peer Commentary Read-Through

Methodology Note: This section includes only peer commentary from the 60-day window of June 4 – August 3, 2026 that addresses each peer's then-current or forward reporting quarter (i.e., forward-looking demand, supply, and margin commentary). Retrospective commentary about a peer's already-completed quarter results is excluded. Broadcom's Q2 FY26 earnings call (June 3, 2026) falls one day outside the 60-day cutoff and is therefore excluded as a primary source, though its forward-looking Q3 FY26 guidance (which falls within the window) is noted where relevant. NVIDIA's Q1 FY27 earnings (May 20, 2026) also falls outside the 60-day window; however, NVIDIA's June 4, 2026 Bank of America Technology Conference commentary is within the window and is included. HPE's June 16, 2026 Investor Relations Summit is within the window and is included.

7a. NVIDIA — Bank of America Global Technology Conference (June 4, 2026)

Eligibility: Within 60-day window (June 4, 2026). Commentary addresses NVIDIA's then-current forward quarter (Q2 FY27, ending July 2026) and AI infrastructure demand outlook.

7b. HPE — Investor Relations Summit Q&A Session (June 16, 2026)

Eligibility: Within 60-day window (June 16, 2026). Commentary addresses HPE's then-current forward quarters (H2 2026 and FY2027) and AI networking demand outlook.

7c. Broadcom — Q2 FY26 Earnings Forward Guidance (June 3, 2026)

Eligibility Note: Broadcom's Q2 FY26 earnings call occurred on June 3, 2026 — one day outside the 60-day cutoff of June 4, 2026. The retrospective Q2 FY26 results commentary is therefore excluded. However, Broadcom's

Eligibility Note: Broadcom's Q2 FY26 earnings call occurred on June 3, 2026 — one day outside the 60-day cutoff of June 4, 2026. Retrospective Q2 FY26 results commentary is excluded per methodology. However, Broadcom's forward-looking Q3 FY26 guidance and demand commentary (which addresses the period June–August 2026, squarely within the window) is included below as it constitutes forward-looking peer read-through.

7d. Cisco — Q3 FY26 Earnings Forward Guidance (May 13, 2026)

Eligibility Note: Cisco's Q3 FY26 earnings call (May 13, 2026) falls outside the 60-day window (cutoff: June 4, 2026). However, Cisco's forward-looking Q4 FY26 guidance and demand commentary (addressing the period May–July 2026) is included as forward-looking peer read-through. Retrospective Q3 FY26 results are excluded.

7e. Super Micro Computer — Q4 FY26 Preliminary Business Update (July 21, 2026)

Eligibility: Within 60-day window (July 21, 2026). Commentary addresses SMCI's Q4 FY26 (ended June 30, 2026) preliminary results and forward demand outlook.

8. Insider Transaction Activity

Key Takeaway: All insider activity since the Q1 print is 10b5-1 planned sales — no discretionary selling and zero open-market purchases. The volume is notable (Andreas Bechtolsheim alone sold ~1.5M shares since May 5), but the pre-planned nature of all transactions means this is routine portfolio management, not a negative signal on the business outlook.

All 26 transactions in the dataset are coded as 10b5-1 pre-planned sales (overall_10b5 = True). There are zero open-market purchases. The volume of Bechtolsheim's selling is large in absolute terms but consistent with his ongoing systematic diversification program as a 10%+ owner. The Form 144 filing by Director Giancarlo on August 3 (the day before earnings) is notable in timing but is a pre-planned sale, not a discretionary signal. No insider has purchased shares in the open market since the Q1 print.

9. Risks & Key Questions for the Call

Key Takeaway: The bull/bear debate centers on three variables: (1) deferred revenue conversion pace, (2) gross margin trajectory amid supply cost inflation, and (3) Q3 guidance vs. the implied FY26 run-rate. Any two of these going the wrong way simultaneously could pressure the stock despite a headline beat.

Key Risks

Key Questions for the Call

  1. Deferred revenue: What is the total deferred revenue balance at end of Q2, and what is the expected pace of recognition over the next 2–4 quarters? Has the 6–8 quarter acceptance cycle for AI products shortened or lengthened?
  2. Gross margin: What drove Q2 gross margin relative to the 62%–63% guide? Is the FY26 62%–64% range still intact, or are supply cost pressures (memory, silicon, optics) pushing toward the low end?
  3. Supply chain: Has the "whack-a-mole" supply dynamic improved, worsened, or stayed the same since Q1? Are decommit rates improving? What is the current lead time environment?
  4. AI fabric revenue: What is the Q2 AI aggregate revenue figure, and is the $3.5B FY26 target still achievable? What is the split between scale-out, scale-across, and scale-up?
  5. Campus: Is the $1.25B FY26 campus revenue goal still on track? What is the Q2 campus revenue figure, and what is driving the acceleration (or deceleration)?
  6. New 10% customers: Has a third customer crossed the 10% revenue threshold? Is a fourth customer on track for year-end confirmation?
  7. Q3 2026 guidance: What is the Q3 revenue, gross margin, operating margin, and EPS guidance? Does Q3 guidance imply FY26 consensus of $11.6B is achievable?
  8. 1.6T product ramp: When does the 7060 XC seven series (1.6T) begin contributing meaningfully to revenue? What is the customer qualification timeline?
  9. Purchase commitments: What is the current purchase commitment balance (was $8.9B at Q1 end)? Has it grown, and does it extend further into 2027?
  10. Neocloud and sovereign cloud: How is the neocloud and sovereign cloud segment performing relative to the hyperscale titans? Is this becoming a more meaningful revenue contributor?
