Shareholder engagement is pivotal in corporate governance, evolving beyond formal resolutions to impact business decisions. This chapter unveils the typically undisclosed dynamics of board-shareholder engagement through a survey of 171 SEC-registered corporations, targeting corporate secretaries, general counsel, and investor relations officers. The survey was complemented by a review of the disclosure on shareholder voting and engagement included in proxy statements filed by Russell 3000 companies during the 2018–2022 meeting seasons. Larger and mid-sized companies more frequently engage than smaller organizations. Engagement, often with major asset managers, can take a confrontational turn, particularly with hedge funds at smaller firms. Topics include executive incentive plans, ESG metrics, GHG emission reduction, workforce diversity, pay equity, and political spending. The study reveals that engagement significantly influences corporate practices, leading to changes, withdrawal of proposals, alterations in proxy votes, and the inclusion of engaged shareholder-nominated directors in management slates.
