Insights

TL;DR Insider sales under a pre-established Rule 10b5-1 plan reduced indirect holdings; disclosure is orderly and not an unscheduled block sale.

The Form 4 documents four separate dispositions on 09/29/2025 by Michael Cannon-Brookes under a Rule 10b5-1 plan adopted February 20, 2025. Each sale lists weighted-average execution prices and the form identifies the remaining indirect holdings (7,665 shares) held via CBC Co Pty Limited as trustee. For investors, the key elements are the use of a pre-established trading plan and detailed price ranges provided in footnotes, which increase transparency about execution timing and pricing.

TL;DR Transactions were executed pursuant to a documented 10b5-1 plan, aligning with standard insider trading compliance practices.

The filing explicitly states the trades were effected under a Rule 10b5-1 plan adopted on February 20, 2025, and provides price ranges and weighted-average prices for each tranche.
