    Sullivan & Cromwell continues to be a perennial leader in financial services M&A in the United States and worldwide. The Firm ranks first by value among law firms advising on financial institutions M&A over the past 15 years, having acted in more than $2.64 trillion in announced transactions worldwide. Since 2010, S&C has acted on more bank M&A deals exceeding $1 billion by deal value than any other law firm, comprising over $171.7 billion in announced transactions.

    The Firm takes a multidisciplinary approach to mergers, acquisitions and dispositions of—and investments in—the full range of financial services companies and businesses. S&C’s financial services lawyers work seamlessly in M&A and strategic matters across the banking, asset management, broker-dealer, exchange, financial technology, specialty finance and insurance sectors. The Firm has advised on some of the most complex and innovative transactions in all of these industry segments.

    S&C’s financial services lawyers deliver creativity, teamwork and collaboration for clients in planning and executing transactions. S&C works on M&A and other strategic assignments of all sizes with the full commitment of the Firm’s resources.

    The Firm’s regulatory and enforcement expertise is a natural complement to its M&A practice. Clients executing M&A transactions in today’s economic landscape rely on the Firm to navigate the transaction, including regulatory obstacles, and manage closing and post-closing risk. This last element has become even more critical to the success of the Firm’s clients as the regulatory environment has caused problems for acquirors in relation to the legacy issues of the institutions and assets they acquire.
