Cooley Alert—US Supreme Court: Pure Omissions Not Actionable Under Rule 10b-5(b)

Earlier this month, SCOTUS unanimously decided Macquarie Infrastructure Corp v. Moab Partners, holding that a pure omission of information required to be disclosed—in this case required in MD&A under Item 303—cannot form the basis of a private securities fraud action under Rule 10b-5(b). The Court was clear: “Pure omissions are not actionable under Rule 10b–5(b).” To be actionable under Rule 10b-5(b), the Court said, the omission must render an affirmative statement materially misleading. According to the Court, a “pure omission occurs when a speaker says nothing, in circumstances that do not give any particular meaning to that silence.”  Actionable “[h]alf-truths, on the other hand, are ‘representations that state the truth only so far as it goes, while omitting critical qualifying information’…….In other words, the difference between a pure omission and a half-truth is the difference between a child not telling his parents he ate a whole cake and telling them he had dessert.” As discussed in this new Cooley Alert, US Supreme Court: Pure Omissions Not Actionable Under Rule 10b-5(b), from our Securities Litigation + Enforcement and Public Companies groups, the “decision emphasizes the importance of assessing whether statements could be construed as being misleading by omission.”
