Summary: written with AI from the case record.

What it's about
The Court said an opinion is not false merely because it proves wrong, but material omissions about Omnicare’s inquiry or knowledge can violate Section 11 if they clash with reasonable investors’ understanding; it wiped out the appeals ruling (vacated it) and sent the case back (remanded) to test the claim.
Section 11 of the Securities Act of 1933 addresses false material facts and important omissions in registration statements.
Question presented
For purposes of §11 of the Securities Act of 1933, may an entity’s opinion statements constitute an untrue statement of fact if the opinion statement is shown to be objectively false without proof that the entity knew the opinion statement was false?
What the Court decided
Holding
1. A statement of opinion does not constitute an “untrue statement of... fact” simply because the stated opinion ultimately proves incorrect. The Sixth Circuit’s contrary holding wrongly conflates facts and opinions. A statement of fact expresses certainty about a thing, whereas a statement of opinion conveys only an uncertain view as to that thing. Section 11 incorporates that distinction in its first clause by exposing issuers to liability only for “untrue statement[s] of... fact. ” §77k(a) (emphasis added). 2. If a registration statement omits material facts about the issuer’s inquiry into, or knowledge concerning, a statement of opinion, and if those facts conflict with what a reasonable investor, reading the statement fairly and in context, would take from the statement itself, then §11’s omissions clause creates liability. 719 F. 3d 498, vacated and remanded.
- Result
- Vacated
The Court's reasoning
The Court distinguished opinions from factual claims: an opinion expresses an uncertain view, so it does not become a false fact just because it proves wrong. But material facts omitted about the issuer’s inquiry or knowledge can create liability if they conflict with what a reasonable investor would understand from the opinion, read fairly and in context.
