Second Circuit Opines on Claims Under Securities Exchange Act - The National Law Review

On November 24, 2021, the U.S. Court of Appeals for the Second Circuit issued a pair of decisions addressing threshold requirements for securities fraud claims under Section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5: (i) pleading a material misstatement or omission, and (ii) demonstrating standing to sue as a “purchaser” or “seller” of a security. In Altimeo Asset Management v. Qihoo 360 Technology Co. Ltd.,1 the Court reinstated Section 10(b) claims premised on the defendants’ alleged failure to disclose in proxy materials a plan to relist the post-merger company on a foreign exchange. In so ruling, the Court parted ways with the district court, which concluded that the proxy materials adequately disclosed the “possibility” of a relisting, and the plaintiffs failed to allege a “concrete” pre-merger relisting plan so as to render the disclosure misleading. In Aiello v. Brown,2 the Court clarified that holders of unexercised preemptive rights to acquire securities—absent “irrevocable liability” to acquire a security—lack standing to assert Section 10(b) claims. We discuss these decisions and the implications for securities litigants below.
