Event summary

The SEC has launched an investigation into RTW Investments' role in Masimo's recent proxy war, specifically regarding an "empty voting" scheme. Masimo alleges that former CEO Joe Kiani and RTW conspired to manipulate shareholder votes, rigging 19% in Kiani's favor through practices like put options or selling shares after record dates. While empty voting is not inherently illegal, Masimo claims evidence of an insider group, which is a red flag for the SEC and potentially the Department of Justice.
