ROSA MORALES is a leading antitrust litigator who represents clients in high-stakes matters, including government enforcement actions, multidistrict litigation, and class actions. She also advises and represents companies and executives in sensitive antitrust investigations involving significant legal, business, and reputational risk.

Rosa has successfully defended clients in numerous “bet-the-company” litigations and trials involving allegations of price-fixing, monopolization, exclusive dealing, tying, bid-rigging, no-poach agreements, and wage-fixing. She regularly represents companies and executives across a range of industries, including healthcare, technology, financial services, pharmaceuticals, telecommunications, and consumer products, as well as public and private higher education institutions.

In addition to her litigation work, Rosa helps clients defend their business practices in antitrust investigations conducted by the U.S. Department of Justice, the Federal Trade Commission, state attorneys general, and congressional committees. She has recently advised clients on matters involving algorithmic pricing, artificial intelligence, and digital platforms.

An active leader in the antitrust bar, Rosa serves on the Executive Committee and as co-chair of the Private Litigation and Class Action Committee of the New York State Bar Association’s Antitrust Section. She also serves as vice chair of the Joint Conduct Committee of the American Bar Association’s Antitrust Law Section and is co-editor of its weekly newsletter, Quick Look. Rosa frequently speaks and writes on emerging competition issues and has recently presented for the American Bar Association, New York State Bar Association, Hispanic National Bar Association, French-American Bar Association, New York City Bar Association, and Columbia University.

Rosa has been recognized as a “Rising Star” (2025) by the Minority Corporate Counsel Association, a “Pro Bono Star” (2025) by Human Rights First, and a “Notable Leader in Law” (2024) by Crain’s New York Business.
