Lissauer will join the firm later this year, stepping into the dual role of global head of Shareholder Engagement and M&A Capital Markets. Based in New York, she will also serve as a Global Chair. The move represents a significant talent acquisition for JPMorgan, as the bank seeks to better anticipate and manage the demands of shareholders in an increasingly volatile financial landscape. Her expertise in defending companies against aggressive activist campaigns is expected to anchor the bank's advisory services, providing clients with a more robust defense mechanism during high-stakes corporate transitions.
