Atlassian faces removal from the Nasdaq-100 index following a formal announcement scheduled for April 10, 2026. The fast-exit rule triggered this action after the company’s index weighting remained below 0.1% for two consecutive months. Atlassian’s stock price fell approximately 50% over the last three months.
The deletion takes effect at the close of trading on April 17, 2026. Passive investment funds tracking the index face an estimated 15 million shares of selling pressure. Sandisk Corp will replace Atlassian in the index.
