Overview
Ryan Tisch provides strategic antitrust counsel for boards of directors, chief executive officers and key business stakeholders as they maneuver government regulations around the world.
Ryan is known for securing approvals for significant mergers facing review in multiple jurisdictions, including some of the largest mergers in the communications, manufacturing, technology, and food and beverage industries. As the digital economy exposes traditional businesses to new competition, clients also turn to Ryan to advise on their evolving business platforms and go-to-market strategies.
Throughout his global practice, Ryan handles matters extensively before the United States Department of Justice and the Federal Trade Commission and manages substantive merger review matters before the United Kingdom’s Competition and Markets Authority, the Competition Tribunal of South Africa, the Australian Competition and Consumer Commission, and China’s State Administration for Market Regulation, among other international authorities. Ryan has a proven track record of leading merger matters from the auction process to a successful resolution, including through trial.
In addition to his deal work, Ryan helps clients mitigate risk on a day-to-day basis. He advises on complex operational issues such as joint venture agreements, trade association activities, standard setting and data exchange. Ryan has particular experience navigating clients’ vertical relationships and distribution systems, and managing antitrust issues associated with resale price maintenance, price discrimination and loyalty incentives.
