Pirani v. Slack Technologies, Inc., et al., Case No. 3:19-cv-05857-SI; Pirani v. Slack Technologies, Inc. (N.D. Cal.); No. 20-16419 (9th Cir. 2021); Slack Technologies, LLC, f/k/a Slack Technologies, Inc., et al., No. 22-200 (2022). The plaintiff brought this class action case against Slack, alleging that Slack's registration statement was misleading because it did not disclose certain information in its registration statement about Slack's service disruptions and how customers were compensated for them.

The United States Supreme Court granted certiorari and in a decision released in June 2023, the Court rejected certain Section 11 arguments and remanded the case to the Ninth Circuit for further consideration of Plaintiff’s Section 11 and Section 12 claims.
