"% of total stake" is the shares in this event against all the vested shares the person held that day, across every share class and holding entity, after that day's vesting. "n/a" means the person's holdings don't reconcile, or the row is a purchase. "Holdings record incomplete" means more shares were sold than the filings show the person held that day, so a percentage would be wrong.

Is this normal? Less than usual: about a third of the 3-year average. 9 insiders sold; the average is 8 a year. Year by year

What stands out

Brian Duffy sold 26% of vested holdings: 33K shares for $3.8M, 22% under a disclosed plan.Largest sale, Aug 14, 2026
Scott Belsky bought 3.1K shares for $498K, first on Nov 3, 2025.Purchase, Nov 3, 2025
Shona Brown sold 528 shares (1.4% of starting holdings), but 1.9K more vested, so the stake grew (from 37K to 38K).Largest sale, Dec 12, 2025

Percentages cover 16 of 18 officers and directors. Left out: James Chuong (most of their shares vested during the period, so a percentage would mislead); Anil Sabharwal (held no vested shares at the start). Disclosed company stock is not an insider's whole wealth.

Who sold, and how much of their stake

Officers and directors, past 12 months. Each bar is the insider's vested stake at the start of the period (Oct 8, 2025). The gold part is what they sold.

Common questions

Is the Atlassian Corp CEO selling stock?

Yes. Michael Cannon-Brookes sold 636K shares ($95.1M, 1.3% of starting holdings) in the past 12 months, all of it under a trading plan disclosed in the filings.

Why are Atlassian Corp insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 95% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 5% were to cover taxes. A trading plan schedules sales in advance.

Are any Atlassian Corp insiders buying?

Yes. 1 officer or director reported 2 purchases in the past 12 months (Form 4 code P, which includes private purchases).

How much of their stake did Atlassian Corp insiders sell?

About 1.4% overall. As a group they still hold 99% of their starting shares. That covers the 12 months to Oct 8, 2026 and counts vested shares reported on SEC Forms 3, 4 and 5, which is not an insider's whole wealth.

18 of 18 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (18 exactly, 0 with a minor or footnoted difference). Percentages cover 16 of 18 officers and directors. Left out: James Chuong (most of their shares vested during the period, so a percentage would mislead); Anil Sabharwal (held no vested shares at the start). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$202M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $202M across 1,367,079 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

The lighter segment is sales with no plan disclosed in the filing ($10.4M), including tax-related sales outside a plan.

Taxes

$10.5M of sales (5.2%) cite tax obligations in their footnotes, $133K of them also under a plan. Example: James Chuong, Aug 19, 2026

Purchases · 1 buyer (2 trades)

1 officer or director bought shares in this period, in 2 trades(Form 4 code P). Across all their filings on record there are 9 purchase trades.

n/an/an/a

Open-market sales (Form 4 code S) by people who were officers or directors, in split-adjusted shares. Earlier years include people who have since left. A sale that an outside holder also reports (a family trust, a fund) is counted with outside holders in every year. Shares, not dollars, are compared, so a change in the stock price doesn't look like a change in selling. Years the filings don't fully cover are shown but left out of the average.

Known gaps and uncertaintyEvery officer and director reconciles

Every officer and director reconciles for this period.

Inferred rename: "Trust" is treated as the same holder as "Farquhar Investment Partnership No. 2", because the old name was never reported again and the new one opened with the same balance (48,630,468 shares). Old name, new name

Inferred rename: "Trust" is treated as the same holder as "Cannon-Brookes Head Trust", because the old name was never reported again and the new one opened with the same balance (48,630,468 shares). Old name, new name

Inferred rename: "Belsky Family, 2018 Exempt Trust" is treated as the same holder as "family trust", because the old name was never reported again and the new one opened with the same balance (6,169 shares). Old name, new name

External context: we only cite outside events when a documented connection exists. None is shown for this period.

Sources and methodology2,020 filings from SEC EDGAR, and how we read them

All 2,020 Forms 3, 4 and 5 filed for Atlassian Corp (SEC CIK 1650372) from Oct 3, 2022 to Sep 22, 2026, retrieved from SEC EDGAR on Oct 8, 2026. Prices are the ones reported in each filing, often weighted averages.

Holdings. Each holding line (a share class plus an owner, such as a trust or LLC) carries its last reported balance forward. Entities first reported during the period start at zero, so transfers between an insider's own trusts don't count as selling. Lines not reported for three years or more are listed separately and left out of totals.

Sales. A sale counts as under a 10b5-1 plan if its footnote cites one or the filing's Rule 10b5-1 box is checked, and as tax-related if its footnote cites tax obligations or sell-to-cover. Shares withheld by the company for taxes are listed separately. Sales with neither attribute are labeled "no plan disclosed".
