Financial Services

Preeminent in its field, our Financial Institutions Practice advises a broad range of financial institutions, private investors and government agencies on transactional and regulatory matters.

We have represented clients in many of the largest and most complex mergers of the past decades, as well as important and innovative capital raising transactions and regulatory matters ranging from compliance with the Dodd-Frank Act and its implementing regulations to chartering new institutions and obtaining regulatory approvals for expanded banking powers. Our clients span the entire spectrum of financial services, including global and smaller domestic banks, insurance companies, asset management firms, securities and mortgage brokers, FinTech companies, credit card issuers and specialty finance firms, as well as investors in these companies and their boards of directors. During the financial crisis and its aftermath, we were at the forefront of advising clients on innovative strategies for recapitalizations and restructurings, as well as purchases of failed banks from the FDIC by banks and private investor clients.

Clients appreciate our unique insight into issues relating to the financial services industry, gained through our extensive deal experience and deep knowledge of the complex and changing regulatory framework. Most of the lawyers in our Financial Institutions Practice have broad experience in both regulatory and transactional matters, giving them an invaluable perspective to address our clients’ needs with practical and creative solutions.
