    The appointment comes at a time when companies across industries face heightened scrutiny from antitrust regulators in the United States and abroad. Mergers and acquisitions, joint ventures, information-sharing arrangements, and compliance obligations continue to attract close attention from enforcement agencies, making experienced antitrust counsel increasingly valuable to global businesses.

    Hine joins Sullivan & Cromwell’s Antitrust Group with extensive experience advising clients on a wide range of competition-related matters. Her practice includes merger review, compliance with the Hart-Scott-Rodino (HSR) Act, competitor collaborations, information-sharing issues, interlocking directorate restrictions, trade association participation, and distribution practices. She has also represented clients before both the Federal Trade Commission (FTC) and the Department of Justice (DOJ) Antitrust Division.

    Prior to joining Sullivan & Cromwell, Hine practiced at Weil, Gotshal & Manges, where she advised clients on complex mergers, acquisitions, collaborations, and antitrust compliance matters. She has also held leadership positions within the American Bar Association’s Antitrust Section, helping shape discussions around merger enforcement and competition policy.

    Strategic Importance for Sullivan & Cromwell

    The addition strengthens Sullivan & Cromwell’s presence in Washington, D.C., a critical hub for antitrust enforcement and regulatory engagement. As regulators continue to examine large transactions in sectors ranging from technology and healthcare to energy and financial services, law firms are increasingly investing in experienced antitrust practitioners who can guide clients through complex investigations and merger reviews.

    For Sullivan & Cromwell, the hire enhances an already prominent antitrust practice that advises multinational corporations, private equity sponsors, and financial institutions on high-stakes transactions and government investigations. The firm’s ability to offer integrated counsel across mergers, litigation, and regulatory matters is likely to benefit from Hine’s experience before federal enforcement agencies.

    A Competitive Market for Antitrust Talent

    Hine’s move also highlights a broader trend within the legal industry: intense competition among elite firms for antitrust talent. Regulatory uncertainty and evolving enforcement priorities have increased demand for lawyers with deep experience in merger clearance, investigations, and compliance.

    Washington, D.C. has become a focal point in this competition, with firms seeking practitioners who can navigate both legal and policy dimensions of antitrust enforcement. Lateral partner moves have become a key strategy for firms looking to expand capabilities and respond to growing client demand in competition law.
