What Went Well and What Went Wrong

• What Went Well

  • “We surpassed $2B in revenue for the first time in Q1 2025 despite the unknowns around tariffs… Arista's trifecta of innovation, growth, and profitability is reflected in our results.” — CEO Jayshree Ullal .
  • Non-GAAP gross margin 64.1% came in above ~63% guidance, driven by a stronger-than-expected mix of non-cloud revenue and minimal tariff absorption impact .

• What Went Wrong

  • Tariff uncertainty elevated risk; management bookended potential gross margin impact at 1–1.5 pts in a worst-case scenario without mitigation .
  • Product deferred revenue volatility increased (+$219M q/q), reflecting new products/use cases and acceptance clauses, potentially amplifying quarterly swings in 2025 .

Q&A Highlights

• Tariffs: Management bookended worst-case GM hit at 1–1.5 pts, with mitigation via absorption, supply chain fungibility, and potential pricing; annual outlook held to avoid frequent updates amid uncertainty .
• AI customers: Four Tier‑1 back-end customers progressing well; two heading to ~50k GPU deployments; three already in production; 1:1 front-end ratio remains a good heuristic .
• Deferred revenue: Product deferred revenue increase tied to new acceptance clauses and trials shifting to production across Etherlink platforms; volatility can be multi-quarter .
• Pull-forward: Some pull-forward ahead of tariff dates, but not significant or material; Q2 seasonally stronger partly reflecting tariff-driven timing .
• Competitive landscape: Coexistence with white box; AI spine typically EOS due to rich routing/telemetry; CPO remains early; Ethernet momentum accelerating across neo-clouds .

Implications: Results beat on revenue, EPS, and GM; EBITDA modestly below consensus likely reflects operating expense timing and other income/tax dynamics discussed by management .

Key Takeaways for Investors

• Beat and raise setup: Strong Q1 beat vs consensus and seasonally stronger Q2 guide (~$2.1B, ~63% GM) position estimates for upward revisions, while annual GM range remains 60–62% amid tariff uncertainty .
• Tariff risk manageable: Worst-case GM impact framed at 1–1.5 pts; mitigation plans include absorption, supply chain flexibility, and potential pricing actions .
• AI pipeline accelerating: Back-end revenue target ($750M) reaffirmed; front-end deployment ratio ~1:1 supports broader AI center revenues; Ethernet gaining ground over IB .
• Demand signals: Product deferred revenue rising (+$219M q/q) and purchase commitments ($3.5B) indicate robust pipeline as trials move to production across Etherlink platforms .
• Capital returns: $787M repurchased in Q1 and new $1.5B authorization provide downside support and confidence in LT value creation .
• Mix watch: Gross margin trajectory driven by customer mix (cloud titans vs enterprise); follow Q2 mix and tariff pass-throughs to gauge full-year GM within 60–62% range .
• Execution focus: Inventory turns stable at 1.4x with buffers; DSOs up to 64 days on linearity; monitor working capital as AI ramps and tariff timing evolve .

Notes
