Columbia Law School’s annual conference on mergers and acquisitions and corporate governance featured speakers from law firms, academia, and the Delaware courts, who unpacked topics such as antitrust policy and enforcement, M&A in politics, AI and M&A, and recent changes in Delaware’s corporate law. Held on November 21 on Columbia University’s Morningside campus, the event was sponsored by the Ira M. Millstein Center for Global Markets and Corporate Ownership; the Center on Corporate Governance; law firms Paul Hastings and Wachtell, Lipton, Rosen & Katz; and financial communications firm Gladstone Place Partners.

The daylong conference included a lunchtime conversation between Eric Talley, Marc and Eva Stern Professor of Law and Business and a faculty co-director of the Millstein Center, and Justice Abigail M. LeGrow of the Delaware Supreme Court. The court is currently considering the constitutionality of the state’s recently enacted law (SB 21; see panel topics, below) that limits shareholder lawsuits against corporate directors and officers for conflicts of interest and self-dealing. The new law is widely viewed as an attempt by Delaware to bolster its advantage as the state where businesses prefer to incorporate.

Without commenting on the case itself, LeGrow said that the recent regulatory moves by Texas and Nevada mark the first time she can recall concerted competition for Delaware’s preeminence in business formation. “There’s nothing wrong with a little competition,” she said. “And if it strengthens our model and helps us innovate, … I think it’s probably not a bad thing in the long run.”

LeGrow added that Delaware’s dependence on corporate franchise tax revenue means the state will always act to protect its position, in contrast to other states that are able to rely on more diverse economic bases. That, she said, “should give people a lot of confidence in the longevity of Delaware as a place to incorporate.”
