Nancy A. Lieberman concentrates on mergers and acquisitions involving public and private companies, including negotiated and contested acquisitions, private equity transactions, tender offers, recapitalizations and restructurings.


Ms. Lieberman advises corporations on various corporate governance issues as well as on responses to shareholder activists. Starting in January 2019, Ms. Lieberman is co-teaching a seminar at Columbia University Law School on the subject of Negotiating M&A Transactions.

Ms. Lieberman is acknowledged as a leading corporate lawyer by various academic institutions, industry publications and the mainstream financial media. In 2015, she was one of 75 attorneys selected for inclusion on the National Law Journal’s list of “Outstanding Women Lawyers” and one of 50 women selected worldwide by Harvard Law School as an honoree for its International Women’s Day celebration. She was recognized as “Alumna of the Year” by The University of Chicago Law School in 2014 and delivered the school’s commencement address.

In 2013, Ms. Lieberman also was named a “Dealmaker of the Year” by The American Lawyer for her work on the termination of Amylin Pharmaceuticals’ alliance with Eli Lilly and Company and the subsequent sale of Amylin for $7 billion to Bristol-Myers Squibb. According to The American Lawyer, this two-step transaction was a “blockbuster combination ... [that] never would have happened without Lieberman’s deft counsel.” Law360 selected Ms. Lieberman as one of its 2012 “M&A  MVPs” for both her work on the Amylin transaction as well as her representation of satellite company DigitalGlobe Inc. and stated that “Lieberman’s steady leadership helped … DigitalGlobe turn the tables on a potential [unsolicited] acquirer in just a weekend’s time.”

Over the years, she has been profiled in The Wall Street Journal, Crain’s New York Business, NYU Law Magazine, Fortune Magazine and the New York Times Magazine, among other publications.
