S. Michael Sirkin

Mike Sirkin litigates corporate and business disputes in the Delaware Court of Chancery and Supreme Court.  He specializes in cases arising from mergers and acquisitions, including appraisal cases and cases involving the fiduciary duties of corporate directors and officers.  Mike also advises clients about the Delaware law and corporate governance issues that arise in a variety of transactional and pre-litigation contexts, including pre-suit demands, conflict-of-interest transactions, books and records requests, and inside-round financings.

Mike has substantial experience litigating valuation issues, having represented respondents in three of the largest appraisal cases in history (BMC Software, Lender Processing Services, and Zale).  Mike also represented the directors of Facebook in a lawsuit in the Court of Chancery challenging their compensation.  In addition, he represented the Kinder Morgan entities in a lawsuit challenging their $75 billion corporate consolidation.  In that case, the Court of Chancery denied the plaintiffs' motion to enjoin the closing of the transaction and granted the defendants' post-closing motion to dismiss the case.  The Supreme Court affirmed the dismissal on appeal.  

Mike is a frequent author and speaker on Delaware law issues.  He has published articles in The Business Lawyer, The M&A LawyerInsights, and Deal Points, and has spoken on panel discussions sponsored by the Private Equity and Venture Capital Subcommittee of the Business Law Section of the American Bar Association and Thompson West.

Mike began his legal career as a judicial law clerk to the Honorable Vice Chancellor J. Travis Laster of the Delaware Court of Chancery.  After his clerkship, he practiced in the Corporate and Business Litigation group of Morris, Nichols, Arsht & Tunnell LLP before joining the firm.  Mike has also participated in the Delaware Volunteer Legal Services Pro Bono Program, successfully obtaining protection from abuse orders for clients in Family Court.

Outside of the firm, Mike is active in the Delaware State Bar Association and the American Bar Association, and he is the President of the Lehigh Lawyers Association.
