Brian Duffy: trading record in brief
Brian Duffy (senior executive) discloses dealings in Atlassian Corp to SEC (Form 4). Over a trading history stretching from 20 February 2025 to 20 September 2026, the count stands at 42 filings.
On the market, this insider has only sold: 38 sales, €2.7M in total. No amount is published for 5 filings, which the totals therefore leave out. Outside the open market, there are 4 share grants. In 2026 alone, the filings show no purchases and 31 sales.
The record was last updated on 22 September 2026 with a share grant in Atlassian Corp. The median gap between a trade and its publication by SEC (Form 4) is 1 day. Section 16 rules allow two business days to file each Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
