• Shares to be sold: 669,403 common shares
• Aggregate market value stated: 65,152,993 (currency not specified in the form)
• Approximate sale date: 26 June 2025 on the NYSE
• Broker: J.P. Morgan Securities LLC, 360 Madison Ave., New York, NY 10017
• Shares outstanding (as listed): 1,255,921,431
• Origin of shares: Stock-option exercises originally acquired on 01 Jan 2013 and later transferred to the 2000 Ullal Family Trust

No other sales of Arista securities by Ullal were reported during the past three months. The filer represents that no undisclosed material adverse information is known. The transaction represents a sizable insider disposition but is executed under a pre-arranged 10b5-1 trading plan, providing regulatory compliance and signaling advance planning.

Positive

• Compliance with Rule 144 and Rule 10b5-1: Sale is disclosed in advance and tied to a pre-arranged plan, reducing information-asymmetry risk.

Negative

• Significant insider sale: Officer/Director intends to dispose of 669,403 shares valued at about $65 m, which may be interpreted as reduced insider confidence.

Insights

Securities Analyst

TL;DR: CEO-linked trust plans 669k-share sale (~$65 m); routine 10b5-1 but notable size.

The planned divestiture equals roughly 0.9 % of Arista’s listed 74 m diluted shares (per latest 10-K; exact current count not supplied here). While Form 144 sales are common, the $65 m value and insider status of Ms. Ullal make the disclosure material for sentiment tracking. Execution under a 10b5-1 plan, adopted six months earlier, limits interpretation of the trade as a near-term signal on fundamentals. No concurrent negative operational data accompany the filing. For a company with a market capitalisation above $90 bn, the dollar size is modest, but investors may monitor additional insider activity to confirm whether this is an isolated liquidity event or the start of a pattern.

Corporate Governance Expert

TL;DR: Large insider sale by officer/director—possible governance red flag despite 10b5-1 protection.

Rule 144 filings provide transparency, yet 669,403 shares from an officer/director-controlled trust is sizable. Even with a pre-arranged plan, concentrated insider selling can raise questions about alignment of management with shareholders. The representation that no undisclosed adverse information exists mitigates legal risk, but perception risk remains. Continued monitoring of insider trend and board communication is advised.
