Kirkland & Ellis Expands Antitrust Practice with Hires of Norman Armstrong, Jr., and Daniel Zach

Kirkland & Ellis announced today that leading antitrust attorneys Norman Armstrong, Jr., and Daniel Zach have joined the Firm as partners. The lawyers join Kirkland’s antitrust and competition practice, which is among the most active for merger control and complex antitrust litigation matters.  

“Norm and Dan are very talented and highly respected attorneys with many years of distinguished service at the Federal Trade Commission as well as in private practice,” said Jon A. Ballis, chairman of Kirkland’s Executive Committee. “They will significantly enhance our already excellent antitrust offering, which provides holistic support to our private equity and corporate clients on their most significant transactions and antitrust litigation.”

Both Mr. Armstrong and Mr. Zach focus on antitrust and competition matters involving complex transactions, government investigations and litigation, including matters before the U.S. Federal Trade Commission, Department of Justice, and federal and state courts. 

“We are thrilled to welcome Norm and Dan, both exceptional attorneys who will strengthen our already strong antitrust team,” said Matt Reilly, antitrust partner at Kirkland. “They have been involved with cutting-edge merger reviews as well as antitrust litigation and bolster our 110-lawyer team of top antitrust attorneys across the U.S. and Europe, helping us meet the demands of our large and growing transactional practice.” 

Kirkland ranked number one for M&A deal value in the Dealogic and London Stock Exchange Group year-end league tables, with the Firm advising on 644 transactions worth more than $400 billion globally in 2023 — amounting to 13% market share. The Firm handled 19% of all Hart-Scott-Rodino premerger notifications filed in 2023, more than any other law firm.

Mr. Armstrong is a former deputy director of the FTC Bureau of Competition. He served in the role from 2008-2014 and oversaw three divisions and the regional offices that investigated anticompetitive transactions and conduct across industries such as healthcare, technology, pharmaceuticals, retail, consumer goods, energy and entertainment.

He is recognized as a leading lawyer by Chambers & Partners, The Legal 500, Global Competition Review and other industry publications. Law360 named him a 2022 Competition MVP.

“Kirkland has the largest deal flow of any law firm in the world, which provides immense opportunity to help clients navigate the evolving antitrust regulatory environment,” said Mr. Armstrong. “The team is also highly collaborative and collegial and that was important for me in making this move.”
