Atlassian Corp. insider Brian Duffy reported transactions in the company’s Class A common stock on June 10, 2026, according to a Form 4 filed June 12. The filing indicates the trades were carried out under a Rule 10b5-1 trading plan that Duffy adopted on March 6, 2026, meaning the sales were prearranged under a plan intended to reduce the appearance of trading on material nonpublic information. The reported activity appears to consist of multiple sales of Atlassian Class A shares. The transactions listed include 1,432 shares at $88.79 per share, 3,000 shares at $89.71 per share, and 1,813 shares at $92.79 per share. Together, those sales total 6,245 shares for estimated gross proceeds of about $564,482, before any taxes, commissions, or other costs. The filing text also shows post-transaction ownership figures of 230,691 shares after one reported transaction and 227,691 shares after a later transaction. Based on the sequence of reported sales, Duffy’s beneficial ownership would have declined further by the final 1,813-share sale, implying remaining ownership of approximately 225,878 Atlassian Class A shares after the reported activity. No option exercise, vesting event, or derivative-security transaction details are described in the provided filing text. The key point of the filing is that Duffy reduced his holdings of Atlassian Class A common stock through pre-planned open-market transactions, with the sales executed at prices ranging from $88.79 to $92.79 per share. The filing was signed on Duffy’s behalf by Veena Bhatia, attorney-in-fact.
