Vice Chair
“Michael is a leader in the litigation world, ascending rapidly to the highest levels due to his excellent courtroom presence, deep knowledge of the law and impeccable judgment.” (Chambers USA, 2024 (Client Quote))
Chambers USA, 2014–2026
Michael is the Head of Vinson & Elkins’ Litigation Department. He is Vice Chair of the firm and a member of the firm’s Management Committee.
Michael is a trial lawyer who focuses his practice on business litigation. He is a seasoned trial lawyer with particular experience in securities and corporate governance matters, including fiduciary duty cases, litigation arising from M&A transactions, securities class actions, corporate governance matter and alternative entity litigation, among other areas. He has appeared as lead counsel in numerous cases pending in federal and state courts around the country, including the Delaware Court of Chancery, as well as arbitral tribunals.
Michael got his first taste for being a lead trial lawyer in a Justice of the Peace Court in Atlanta, Texas shortly after joining the firm in 1997. Since then, he has litigated and tried several significant cases, including some of the largest, most high-profile cases. As examples: In 2009, Michael was on the trial team that a won a judgment ordering Hexion to close its merger with Huntsman. In 2016, Michael led a trial team that won a judgment allowing Energy Transfer to terminate its transaction with The Williams Companies, and in 2019 he led a trial team that won a take-nothing judgment for a publicly-traded company against a $1.6 billion entire fairness claim.
Michael has earned the praise and respect of trial lawyers on both sides of the bar.
“As trial lawyers, we accept that we will win some and we will lose some. Of course winning is always better. And I have to tip my hat to Michael, since he finds a way to win cases that I thought he’d surely lose.”
–Lawdragon, 2021 (Former Adversary Quote)
“Michael Holmes is a rock star with a good strategic mind and who often handles matters in Delaware.”
–Legal 500 US, 2019 (Market Commentary)
