Abstract: This Article investigates the time of COVID-19 to test the claims of supporters of stakeholder capitalism (“stakeholderism”). Such supporters advocate encouraging and relying on corporate leaders to use their discretion to serve stakeholders such as employees, customers, suppliers, local communities, and the environment. The pandemic followed and was accompanied by peak support for stakeholderism and broad expressions of commitment to it from corporate leaders. Nonetheless, and even though the pandemic heightened risks to stakeholders, we document that corporate leaders negotiating deal terms failed to look after stakeholder interests. Some supporters of stakeholder capitalism argue that corporate leaders should and do give weight to stakeholder interests because delivering value to stakeholders is a major element of corporate purpose. Other supporters maintain that corporate leaders considering a sale of the company should and do seek to benefit stakeholders, because fulfilling implicit promises to do so serves shareholders’ ex ante interest in inducing stakeholder cooperation, arguably essential to corporate success. We find that the evidence is inconsistent with the claims of both views. We conduct a detailed examination of all the $1B+ acquisitions of public companies that were announced during the COVID pandemic, totaling more than 100 acquisitions with an aggregate consideration exceeding $700 billion. We find that deal terms provided large gains for the shareholders of target companies, as well as substantial private benefits for corporate leaders. However, although many transactions were viewed at the time of the deal as posing significant post-deal risks for employees, corporate leaders largely did not obtain any employee protections, including payments to employees who would be laid off post-deal. Similarly, we find that corporate leaders failed to negotiate for protections for customers, suppliers, communities, the environment, and other stakeholders. After conducting various tests to examine whether this pattern could have been driven by other factors, we conclude that it is likely to have been driven by corporate leaders’ incentives to benefit stakeholders only to the extent needed to serve shareholders’ interests. While we focus on decisions in the acquisition context, we explain why our findings also have implications for ongoing-concern decisions, and we discuss and respond to potential objections to our conclusions. Overall, our findings cast substantial doubt on the claims made by supporters of stakeholder capitalism. Those who seriously care about corporations’ external effects on shareholders should not harbor illusory hopes that corporate leaders would protect stakeholder interests on their own. Instead, they should concentrate their efforts on securing governmental interventions (such as carbon taxes and employee protection policies) that could truly protect stakeholders.
