Atlassian Jumped More Than 30% After Guiding Next Year's Growth Down to 18%. The Market Bought the Margins.

Atlassian (TEAM) surged over 30% after reporting fourth-quarter results that showed GAAP profitability despite guiding subscription ARR growth down to 18% for fiscal 2027 from 23%. The market looked past the deceleration and rewarded margin expansion.

The company posted Q4 revenue of $1.77 billion, up 28% year-over-year, with a 12% operating margin and $139 million in net income—a swing from prior-year losses. Cloud revenue hit $1.2 billion, accelerating 31%, and management expects cloud to sustain mid-20% growth rates through fiscal 2027.

Total revenue growth is projected to slow to 13% next year as the mix shifts toward higher-margin cloud subscriptions. The move to GAAP profitability marks a turning point for the collaboration software maker, which has prioritized growth over earnings in prior years.

The rally suggests investors are betting the margin story offsets slower top-line expansion. Atlassian's cloud transition is gaining traction, but the guidance pullback on ARR growth introduces execution risk as the company balances profitability with customer acquisition.
