So what

Atlassian delivered another strong round of growth. Revenue jumped 40% in the period to $243.8 million, beating estimates of $233 million, as the company added 6,600 net new customers in the quarter to finish the fiscal year with 125,796 customers. On an adjusted basis, operating margin rose from 14% to 19%, and the company reported earnings per share of $0.13, up from $0.09 a year ago. That also topped expectations by a penny.

However, the bigger news in the report seemed to be Atlassian's new strategic partnership with Slack, the privately held office-messaging platform. Atlassian said it would sell the intellectual property of its two messaging products, HipChat and Stride, to Slack, which would discontinue the products. Management said the two companies would deepen existing product integrations such as Jira Cloud, Bitbucket Cloud, Trello, and the eponymous Slack.

The market cheered the move, as it both eliminates competition for Atlassian and gives the company a powerful new collaborator. Atlassian also made an equity investment in Slack for an undisclosed amount.

Now what

For the fiscal year ahead, Atlassian sees revenue of $1.146 billion to $1.154 billion, representing 31.6% growth, and projects an adjusted operating margin of 20%, along with adjusted EPS of $0.77, up from $0.49 last year. Shares had already been on a run before the recent earnings report, gaining 42% through the first half of the year. The partnership with Slack should only enhance the company's position in enterprise solutions -- Atlassian already serves two-thirds of the Fortune 500.

There's good reason to expect more growth ahead for Atlassian.
