Giancarlo Charles, a director of Arista Networks, sold 8,000 shares in a series of open-market transactions on July 1, 2026, generating roughly $1,336,472 in proceeds (overall weighted-average ≈ $167.06/share).

Context

• A 10b5‑1 plan means these were pre-scheduled trades and are often considered routine, not a direct signal of the insider’s current view of the company.
• Sales by directors are common for diversification or liquidity; purchases generally carry more informational weight for bullish signals.
• If you track insider activity, note the apparent late filing — regulators require timely reporting and late filings may attract scrutiny.
