McDermott Will & Schulte is a go-to for activist investors running campaigns where the margin between leverage and overreach is defined by execution. The team pairs campaign strategy with tight control of the mechanics that decide outcomes in practice: nomination and notice requirements, proxy and disclosure rules, and the sequencing of engagement and public messaging when negotiations harden. The New York-based practice is particularly effective in matters that sit at the intersection of activism and complex structures, including closed-end fund campaigns, transaction-adjacent activism, and situations where litigation risk and securities issues shape the path forward. Eleazer Klein leads the practice and is closely involved in the firm’s most sensitive live engagements, guiding clients through escalation points and settlement dynamics. Marc Weingarten remains a key figure on major shareholder-side mandates. Brandon Gold and Abraham Schwartz are integral to day-to-day campaign execution, from engagement planning through nominations and settlement documentation. Adriana Schwartz has left the firm.
