X / SOCIAL CHATTER
Arista raised 2026 AI revenue target to $3.5B and full-year guidance to $11.5B after Q1 grew 35%. "@JasonL_Capital: $ANET - Arista Networks Q1 revenue $2.709B, up 35% YoY. Meta and Microsoft are anchor customers, accounting for roughly 48% of 2025 revenue. Raised 2026 AI networking revenue target to $3.5B." Wolfe Research reiterated Outperform ($175 PT) citing improving supply and tokenomics focus. "@knockouttrader: Wolfe came away from meetings with $ANET sounding increasingly constructive... supplychain debate fading."

MANAGEMENT CREDIBILITY
9/10. Delivered beats every quarter since Q2 2024; raised 2026 growth target from 17% to 27.7% without moving goalposts. Transparent on supply constraints and tariffs; only minor flag is one stalled AI trial customer.

KEY CATALYSTS
Q2 2026 earnings (late July); further AI cluster wins; supply-chain improvement updates.

KEY RISKS
Hyperscaler concentration (Meta/Microsoft ~48% of 2025 revenue); valuation compression if AI spend decelerates; persistent component shortages.

BOTTOM LINE
Strong AI-driven growth, pristine execution, and analyst support outweigh near-term bearish options/insider flow. Current price offers reasonable entry ahead of continued 2026 AI ramp.
