Case Brief Summary & Legal Analysis
tl;dr: The SEC sued Mark Cuban for insider trading. The Fifth Circuit reversed a dismissal, finding it plausible that Cuban’s agreement to keep information about a stock offering confidential also included an implicit agreement not to trade on that information, creating a duty under the misappropriation theory.
Legal Significance: The case clarifies that, under the misappropriation theory, a plausible claim for insider trading can be based on an implicit agreement not to trade, inferred from the context of a confidentiality agreement and the parties’ conduct, without needing an explicit prohibition on trading.

Case Facts & Court Holding
Key Facts & Case Background
Mark Cuban, a 6.3% shareholder in Mamma.com, was contacted by the company’s CEO about a pending private investment in public equity (PIPE) offering, which would likely dilute existing shares and lower the stock price. The CEO first secured Cuban’s agreement to keep the information confidential before disclosing it. Upon learning of the PIPE, Cuban allegedly stated, “Well, now I’m screwed. I can’t sell.” The CEO and other board members appeared to understand that Cuban recognized he could not trade until the PIPE was publicly announced. Nevertheless, after obtaining more details about the PIPE’s discounted pricing from the company’s investment banker, Cuban sold his entire stake in Mamma.com, avoiding over $750,000 in losses. The SEC sued Cuban for insider trading under the misappropriation theory, alleging he breached a duty of trust and confidence owed to Mamma.com. The district court dismissed the complaint, finding it alleged only a duty of confidentiality, not a duty to abstain from trading.
Court Holding & Legal Precedent
