Overview

• The all-cash deal is slated to close in Atlassian’s fiscal second quarter, which ends in December, subject to regulatory approvals.
• Atlassian will use cash on its balance sheet to fund the purchase and does not expect a material impact on fiscal 2026–2027 results.
• Dia, in beta since June, becomes the priority product, while Arc will be maintained but not actively developed.
• Atlassian plans to merge Arc’s power-user concepts, Dia’s AI capabilities, and its enterprise security and admin controls to create a work-optimized browser experience.
• The acquisition enters a crowded AI-browser race led by incumbents and startups, with Chrome holding about 69% market share and rivals such as Perplexity and Brave adding agentic features.
