Insights

CEO Michael Cannon-Brookes sold 7,665 shares under a pre-established trading plan, retaining significant ownership stake.

This Form 4 filing discloses that Michael Cannon-Brookes, Atlassian's CEO, Co-Founder, Director, and 10% owner, sold 7,665 shares of Class A Common Stock on June 23, 2025, at prices ranging from approximately $188 to $194 per share. The transactions were executed through six separate trades at different price points, with the largest block being 3,800 shares sold at a weighted average price of $192.75.

Notably, these sales were conducted pursuant to a Rule 10b5-1 trading plan established on February 20, 2025. Such plans allow insiders to pre-schedule trades to avoid concerns about trading on material non-public information. This structured approach to selling is common among executives with substantial equity positions.

Following these transactions, Cannon-Brookes still indirectly owns 38,325 shares through the Cannon-Brookes Head Trust. The shares sold represent approximately 16.7% of his reported holdings prior to the transactions. Despite this reduction, his continued substantial ownership position and leadership roles (CEO, Director, Co-Founder, 10% Owner) demonstrate ongoing alignment with shareholders.

The timing and execution of these sales through multiple tranches at varying price points suggest a methodical approach to the planned divestiture, rather than urgent liquidation. This pattern of selling shares under a pre-established plan is consistent with normal portfolio management practices for executives with significant equity compensation.
