Atlassian Co-CEOs Adopt New 10b5-1 Trading Plans

SAN FRANCISCO (May 25, 2017) - Atlassian Corporation Plc (NASDAQ: TEAM), a leading provider of team collaboration and productivity software, today announced that Scott Farquhar and Mike Cannon-Brookes, co-CEOs, co-founders and directors of Atlassian, each adopted a new stock trading plan in February 2017 in accordance with guidelines specified under Rule 10b5-1 of the Securities and Exchange Act of 1934, as amended, and the policies of Atlassian regarding stock transactions.  

These pre-arranged trading plans were adopted in order to allow Messrs. Farquhar and Cannon-Brookes to sell a portion of their Atlassian stock over time as part of their long-term strategies for individual asset diversification and liquidity. Using these new trading plans, they will diversify their investment portfolios and spread stock trades out over a period of a year from the time their current trading plans expire in June 2017 to reduce market impact on any given day. All sales of shares under Messrs. Farquhar’s and Cannon-Brookes’ trading plans are subject to volume limitations, pursuant to Rule 144, which limits the amount of shares that can be sold in any three-month period. 

In the aggregate, Messrs. Farquhar and Cannon-Brookes currently hold approximately 133.78 million Class B ordinary shares and 525,556 Class A ordinary shares, which represent approximately 58.95% of Atlassian’s outstanding Class A and Class B ordinary shares, taken together, and approximately 92.59% of the voting power. Under the terms of the new trading plans, Messrs. Farquhar and Cannon-Brookes each intends to sell up to approximately 2.64 million Class B ordinary shares (with such shares converting into Class A ordinary shares prior to sale). If Messrs. Farquhar and Cannon-Brookes complete all the planned sales under their current and new trading plans, they would continue to collectively own approximately 128.87 million Class B ordinary shares, which would represent approximately 56.56% of Atlassian’s outstanding Class A and Class B ordinary shares, taken together, and approximately 91.97% of the voting power (assuming no other issuances, repurchases, sales or conversions of Atlassian’s capital stock occur). Each Class B ordinary share is entitled to ten votes and each Class A ordinary share is entitled to one vote.
