Macquarie Infrastructure Corp. v. Moab Partners, L. P.
Headline: Court rules that mere silence about required SEC disclosures cannot by itself support private fraud suits, limiting investors’ ability to sue companies for nondisclosure unless prior statements are rendered misleading.
Holding:
- Limits private securities suits based solely on nondisclosure of Item 303 information.
- Requires plaintiffs to point to misleading statements, not just silence.
- Leaves SEC authority to enforce disclosure rules and registration-law claims intact.
Summary
Background
An infrastructure company that runs large liquid storage terminals did not mention a new international shipping rule (IMO 2020) that sharply limited use of a high-sulfur fuel its terminals stored. An investment firm sued after the company reported falling contracted storage and its stock dropped about 41%, arguing the company broke SEC disclosure rules and committed securities fraud by failing to tell investors about the regulatory change.
Reasoning
The Court addressed whether a private fraud claim under the federal anti-fraud rule (Rule 10b-5(b)) can be based solely on a company’s failure to disclose information required by SEC Item 303. The Court explained that Rule 10b-5(b) bans lies and those omissions that make earlier statements misleading (half-truths), but does not create liability for pure silence. Because the rule refers to “statements made,” the Court held that silence alone—without some affirmative statement rendered misleading—does not give rise to a private Rule 10b-5(b) claim. The Court noted that other parts of the law, like a separate registration statute and the SEC’s enforcement authority, can address pure omissions.
Real world impact
The ruling means investors cannot rely on Rule 10b-5(b) alone to sue companies for failing to disclose Item 303 information unless they show an earlier statement was made misleading by that omission. Plaintiffs must point to misleading statements (half-truths) rather than mere silence. The SEC still can enforce disclosure rules, and other statutory claims remain available.
