In a securities class action under Section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5 thereunder, plaintiffs seeking to plead a violation must allege “with particularity facts giving rise to a strong inference” that each defendant made a material misrepresentation or omission with scienter, i.e., a “mental state embracing intent to deceive, manipulate, or defraud.”1 When the defendant is a corporate entity—with no single mind of its own—whose state of mind matters for purposes of the scienter analysis?

As the U.S. Court of Appeals for the Sixth Circuit recently asked in In re Omnicare, Inc. Sec.
