The Supreme Court Solidifies the Securities Act’s Tracing Requirement For Section 11 Plaintiffs
June 9, 2023 | Blog | By Doug Baumstein, Jason Vigna, Ellen Shapiro, Aaron R. Megar
Last week, the U.S. Supreme Court solidified the “tracing” requirement for private plaintiffs to be able to assert Section 11 claims pursuant to the Securities Act of 1933, holding that plaintiffs asserting such securities fraud claims must show that they own stock that was issued pursuant to an allegedly misleading registration statement—even though such tracing may be impossible in the context of a direct listing. In effect, the decision likely protects future direct listings from Section 11 liability so long as the direct listing does not involve a “lock-up period” pursuant to which unregistered and registered shares enter the market at different times.
