What We Know

Slack went public through a direct listing on the New York Stock Exchange in June 2019, trading under the ticker WORK. Rather than a traditional IPO, the company chose a direct listing approach that allowed existing shareholders to sell shares without raising new capital. The listing was successful and the stock performed well initially. In December 2020, Salesforce announced its acquisition of Slack for approximately $27.7 billion, which was completed in July 2021. The all-cash and stock deal was one of the largest software acquisitions at the time. Following the acquisition, Slack became part of Salesforce and is no longer traded as a separate public company, though it continues to operate as a product within Salesforce's ecosystem.
