Matthew ReillyKirkland & Ellis LLP

Kirkland & Ellis LLP takes on both US and foreign mergers clearances, hence filing numerous HSR notifications as well as handling second requests on a regular basis. ‘Exceptionally knowledgeable and strategic’ antitrust teams in Chicago, New York, Washington DC and Dallas work closely with the firm’s M&A department to handle antitrust aspects of transactions. Practice strength is evenly balanced across locations: Washington DC fields Matthew Reilly, healthcare expert Marin Boney and Michael DeRita. Katherine Rocco, global transactional practice co-head Ian John and Peter McCormack are all located in New York. Chicago is James Mutchnik‘s playing field, which includes a white-collar crime defense practice in addition to antitrust merger advice. The Dallas office recently received a significant boost with the arrival of Sean Royall and Olivia Adendorff from Gibson, Dunn & Crutcher LLP in November 2019. Richard Cunningham relocated to Washington DC.
