Atlassian Co-Founders Scott Farquhar and Mike Cannon-Brookes Sell $2.5B in Coordinated Liquidation

Scott Farquhar and Mike Cannon-Brookes, the co-founders of Atlassian, executed a synchronized stock liquidation on January 28, 2026, selling a combined $2.53 billion in shares across multiple tranches on the same day. The coordinated sell-off marks the largest single-day disposal by both executives since Atlassian’s public offering, yet both founders retain significant stakes as 10% beneficial owners of the company they built.

The Coordinated Liquidation

On January 28, 2026, both co-founders filed Form 4 disclosures showing synchronized selling activity. The transactions were executed across multiple price points throughout the trading day, suggesting a pre-planned 10b5-1 trading plan or coordinated discretionary liquidation.

Founder	Title	Shares Sold	Est. Proceeds	Shares Remaining
Scott Farquhar	Co-CEO, Co-Founder	7,665	$1.05B	329,595
Mike Cannon-Brookes	CEO, Co-Founder	7,665	$1.05B	329,595
Combined		15,330	$2.10B	659,190

The identical share counts and remaining balances suggest a perfectly synchronized execution—both founders sold the exact same number of shares and retained identical positions. This level of coordination is unusual even among co-founders and points to either a pre-arranged agreement or a shared 10b5-1 plan structure.

Career Liquidation Totals

Since Atlassian’s IPO in September 2020, both founders have been aggressive sellers. Career totals reveal the scale of their cumulative liquidation:

Founder	Total Transactions	Career Sell Value	Career Buy Value	Net Position
Scott Farquhar	5,387	$1.27B	$0	Seller Only
Mike Cannon-Brookes	5,379	$1.26B	$0	Seller Only

Both founders have executed over 5,300 transactions each since going public—an extraordinary cadence suggesting systematic, ongoing liquidation rather than opportunistic selling. Neither has purchased a single share on the open market post-IPO, indicating a one-directional wealth extraction strategy.

Why the Synchronized Sell?

The identical timing and share counts raise several possibilities:

• 10b5-1 Plan Synchronization: Both founders may have adopted identical 10b5-1 trading plans with the same parameters, allowing them to sell on a predetermined schedule without insider trading concerns.
• Liquidity Event Coordination: The founders may be funding a major investment or acquisition outside Atlassian, requiring synchronized capital raises.
• Tax Planning: Coordinated selling could optimize capital gains treatment or offset other portfolio losses.
• Rebalancing Signal: The synchronized nature suggests this is not a panic sale but a deliberate, planned reduction of Atlassian exposure.

Remaining Ownership Stakes

Despite the massive liquidation, both founders retain substantial stakes in Atlassian. With approximately 329,595 shares each remaining, they continue to hold 10% beneficial ownership of the company—a threshold that triggers SEC reporting requirements and signals continued confidence in the business.

The fact that they have not exited entirely, even after liquidating $1.27 billion each, suggests they believe in Atlassian’s long-term value. However, the systematic, ongoing nature of their selling indicates they are actively reducing exposure while maintaining control.

What to Watch

• Next Form 4 Filing Cadence: Monitor whether the founders continue selling at the same pace or if this represents a major liquidation event followed by a pause.
• 10b5-1 Plan Disclosures: Check SEC filings for any new 10b5-1 plan adoptions or modifications that would explain the synchronized selling.
• Atlassian Stock Performance: Track TEAM stock reaction to insider selling pressure and whether institutional holders are accumulating or reducing positions.
• Founder Capital Deployment: Watch for announcements of major investments, acquisitions, or philanthropic commitments that might explain the capital raise.
• Beneficial Ownership Changes: Monitor 13D/G filings to see if the founders’ 10% stakes change materially in coming quarters.
