Lou Kling has been one of the leading M&A lawyers in the United States over the past 30 years. Until becoming of counsel at the end of 2015 (when he was named a "Senior Statesman" by Chambers), he consistently had been one of a small number of attorneys included in its highest-ranked tier of M&A attorneys.


Mr. Kling has been included in Euromoney’s listing of the leading M&A lawyers in the world and repeatedly has been recognized as a leading lawyer in corporate and M&A transactions by Chambers Global and Chambers USA, and also has been listed in The Best Lawyers in America, The Legal 500 U.S., Lawdragon 500 Leading Lawyers in America, IFLR1000 and Who’s Who Legal — M&A. In 2016, Mr. Kling was named to the Lawdragon Hall of Fame in the Dealmakers category.

He has been an adjunct professor at University of Virginia School of Law for more than 15 years, as well as at University of Pennsylvania School of Law for 2019 and 2020, and NYU Law School for 2020. He also has taught courses at Cornell Law School and has appeared numerous times as a guest lecturer at Harvard, Yale, University of Pennsylvania and NYU law schools. He is the co-author (with his partner) of Negotiated Acquisitions of Companies, Subsidiaries and Divisions, a two-volume treatise, which has been the leading work in its field for more than 25 years.

Until recently (as part of his moving to an of counsel role at the firm), Mr. Kling served for more than 15 years as the head of the firm’s Financial Oversight and Audit Committee, as the head (or co-head) of the firm’s Opinion Committee and as a member of the firm’s Policy Committee.

Mr. Kling has worked on dozens of multibillion-dollar transactions for companies such as DuPont, Express Scripts, 21st Century Fox (formerly named News Corporation), Ford, Warner Lambert, McDonnell Douglas, Chris-Craft, Lockheed Martin, Howard Hughes Medical Institute, Jefferson Smurfit and Xerox. He also has worked on numerous small- and mid-cap transactions. While he has primarily represented corporate buyers and targets, he also has represented numerous private equity groups, as well as financial advisors (including Goldman Sachs, Morgan Stanley, First Boston/Credit Suisse, Merrill Lynch and Salomon Brothers). He also has represented borrowers and issuers in billions of dollars of financings.
