Atlassian Q1 2027: Strong Beat, But the Growth Guide Stings

Atlassian posted adjusted EPS of $1.65 for its fiscal first quarter of 2027, clearing the $1.43 consensus by roughly 16% and extending a streak of consecutive quarterly EPS beats to six. Revenue came in at $1.77 billion, up about 24% year-over-year and about 3.4% ahead of the $1.71 billion estimate. On the surface, those are strong numbers.

The stock dropped roughly $30 within minutes of the filing, and the culprit is the full-year guide. Management is targeting total revenue growth of about 13.75% for all of fiscal 2027, a sharp deceleration from the 24% pace the company just delivered in Q1. For investors who had priced in continued momentum, that gap is what triggered the selloff.

Cloud revenue surged 31% to $1.30 billion, the clear engine of the business. But Data Center revenue is expected to decline about 16% for the full year as customers migrate away from on-premise deployments. That migration is strategically healthy, and it is also mathematically painful, because a fast-growing segment replacing a shrinking one leaves headline growth rates looking considerably more modest in the near term.

For Q2, Atlassian guided to Cloud growth of about 27% and a Data Center contraction of roughly 14%. Non-GAAP operating margin is targeted at about 26% for Q2 and about 25.5% for the full year, suggesting the company sees profitability expanding even as top-line growth cools.

CEO Mike Cannon-Brookes highlighted remaining performance obligations up 44% year-over-year and noted that Teamwork Collection customers grew 7x year-over-year. Those figures point to durable demand building in the pipeline, even if that demand does not translate immediately into recognized revenue. Free cash flow of $463 million, representing a 26% margin, adds another layer of financial solidity beneath the softer growth outlook.

The tension the market is now pricing is straightforward: an operationally healthy business with a cloud transition that compresses near-term reported growth. How quickly Data Center headwinds fade and whether Cloud can sustain growth above 26% are the two variables that will determine whether today's selloff looks like an overreaction or a rational re-rating.
