The U.S. Supreme Court held that purchasers of shares sold to the public through a direct listing cannot sue under Section 11 of the Securities Act of 1933 unless they can trace their shares to an allegedly defective registration statement. The short, unanimous decision in Slack Technologies, Inc. v. Pirani (June 1, 2023) appears likely to increase the difficulty of pleading § 11 claims arising from direct listings, thereby requiring dissatisfied purchasers to resort to the Securities Exchange Act of 1934, which imposes stricter standards for liability. The Court declined to comment on Securities Act § 12(a)(2)’s requirements, leaving the issue for the Ninth Circuit on remand.
