Fried, Frank, Harris, Shriver & Jacobson LLP’s antitrust merger control team works hand-in-glove with the firm’s corporate and litigation practices across the US and Europe, advising on complex, high-profile transactions alongside investigations and contentious proceedings. Spearheading the team is Barry Nigro, who splits his time between Washington DC and New York and brings former DOJ Antitrust Division leadership experience to large-scale merger reviews and contested clearance strategies. In New York, Aleksandr Livshits is particularly active on technology-driven and software transactions, while Lexi Michaud regularly advises on HSR strategy and filings. Kathy O’Neill joined the team from Cooley LLP, having previously held senior leadership roles at the DOJ’s Antitrust Division, and brings enforcement-side perspective to merger clearance work and contested review.
