Background

  • Slack conducted a direct listing on the NYSE in 2019, filing a registration statement for 118 million registered shares while 165 million unregistered (preexisting) shares were simultaneously available for sale.
  • Fiyyaz Pirani purchased Slack shares the day of the listing and later; he sued, alleging the registration statement contained material misstatements or omissions in violation of §11 (and §12) of the Securities Act of 1933.
  • §11 imposes strict liability for material misstatements or omissions in a registration statement; the dispute centered on whether a §11 plaintiff must have purchased securities traceable to the challenged registration statement.
  • The district court denied Slack’s motion to dismiss; the Ninth Circuit affirmed in a divided decision, creating a circuit split by allowing §11 claims even when plaintiff’s shares were not traceable to the registration statement.
  • The Supreme Court granted certiorari and held that §11 requires a plaintiff to plead and prove he purchased securities registered under the allegedly defective registration statement; the Ninth Circuit’s judgment was vacated and remanded.

Issues

Issue Plaintiff's Argument Defendant's Argument Held
Whether §11(a)’s phrase “such security” permits suits by purchasers of shares not traceable to the challenged registration statement "Such security" can include unregistered shares that bear a sufficient relationship to the registered offering (e.g., unregistered shares sold only because the registration existed) "Such security" means securities issued pursuant to the specific registration statement; plaintiff must trace purchases to that registration §11(a) requires the plaintiff to plead and prove purchase of securities traceable to the allegedly defective registration statement; case vacated and remanded
