A&O Shearman continues to expand Antitrust offering with partner addition in Washington, D.C.

A&O Shearman announces today the addition of partner Anna Kertesz to its U.S. Antitrust practice in Washington, D.C. 

Anna brings more than 20 years of antitrust experience in merger clearance, antitrust and consumer protection counseling, and civil and criminal antitrust litigation and investigation, including several years at the U.S. Federal Trade Commission investigating mergers and acquisitions (M&A) transactions with the Mergers 1 (Pharma) and 3 (Oil & Gas) units.

Her combination of government and private practice experience allows her to provide practical, strategic insights to clients navigating complex antitrust matters across a wide variety of industries, including key client verticals such as life sciences, technology, oil and gas, retail and consumer products, and industrial equipment.

Adam Hakki, co-chair of the global Executive Committee and Board, and U.S. chair at A&O Shearman, said: “Anna is an important addition to our Antitrust and M&A offering, bringing deep experience in complex merger clearance and antitrust counseling, including government experience, to our market-leading U.S. and global teams. This is the second Antitrust lateral partner we have recruited in the U.S. this year, complementing our exciting growth in U.S. M&A capability. We’re delighted to welcome Anna.” 

“Anna is a standout addition to our Antitrust team, bringing deep experience across complex transaction reviews, investigations, and litigation. Her ability to navigate challenging regulatory environments and engage effectively with enforcement agencies makes her an excellent asset as demand continues to grow,” said Noah Brumfield, head of U.S. Antitrust at A&O Shearman.

“I’m excited to join a firm with a clear commitment to growth and to delivering exceptional counsel to its clients, wherever they are based. I look forward to working with A&O Shearman’s talented teams and to helping clients navigate the increasingly sophisticated and evolving enforcement landscape.”

Anna joins A&O Shearman from White & Case.

Anna’s arrival builds on A&O Shearman’s continued investment in growing its Antitrust offering, which was strengthened this year with the recent addition of Kathryn Mims as an Antitrust partner in Washington, D.C.

The firm has recently welcomed a series of lateral partner hires that together further build out its U.S. capabilities: Steve Tyndall (Mergers and Acquisitions in Austin), Germaine Gurr (M&A in Los Angeles), Joseph Brown (Restructuring in New York), Matthew Karlyn (Digital, Data, IP and Technology in Boston), W. Andrew Lanius (Energy, Natural Resources, and Infrastructure in Houston), Kathryn Mims (Antitrust in Washington, D.C.), Paul Astolfi (Energy, Natural Resources, and Infrastructure in Dallas), Katy McNeil (Energy, Natural Resources, and Infrastructure in Chicago), Michael Kim (Capital Markets in New York), Ned Schodek (Restructuring in New York), Jan Sysel (Fund Finance in New York), Valentine Bleicher (M&A in Chicago), Nick Ramphal (M&A in New York), and Catherine Hein (International Trade and CFIUS in Washington, D.C.).
