William (Bill) M. Regan
Partner Litigation, Arbitration, and Employment
To achieve this goal, Bill begins each case by working closely with the client to marshal the critical facts and efficiently and compellingly present the client's legal position to the court or regulator as early as possible. This intensive "up-front" approach to litigation regularly results in pleading-stage dismissals and terminated regulatory investigations.
Bill is a partner in Hogan Lovells' Securities, Shareholder and M&A Litigation group. He has more than 20 years of experience representing public and private companies in all types of securities litigation matters, including class actions under the Securities Act of 1933 and the Securities Exchange Act of 1934, stockholder derivative suits, SEC and FINRA investigations, internal and special committee investigations, and M&A and corporate governance disputes. Bill's securities litigation matters have involved corporate culture and #metoo allegations, accounting improprieties, missed earnings forecasts, regulatory violations, and representations concerning FDA approval of new drug applications. In the M&A space, Bill has represented clients in cases concerning false statements in proxy and tender offer disclosures, indemnification in connection with representation and warranty breaches, earn-out disputes, purchase price adjustments, and material adverse change issues.
In addition to his work for public and private issuers, Bill regularly represents financial institutions on securities-related matters. Recently, Bill has represented some of the world's largest international financial services firms in U.S. legal proceedings concerning repurchase agreements, CMBS, RMBS, hedge-fund linked derivatives, futures, commercial credit facilities, trading accounts, and real estate and construction loans.
