Private Equity

Simpson Thacher is quite simply the world’s leading legal advisor in the private equity sector. Since the earliest days of private equity, clients have sought our advice on fund formation, minority investments, mergers and acquisitions, financing solutions and exit transactions. Significantly, we have represented the private equity sponsor in the five largest leveraged acquisitions ever completed.

Our scale and depth give us insight into the needs of every participant in private equity transactions: private equity sponsors, senior bank lenders, subordinated and bridge lenders, management and financial investors and underwriters. We have partnered with our clients as trailblazers in developing various acquisition and financing techniques in the private equity field, and we continue to be the firm of choice for many of the world’s largest and most sophisticated private equity firms.
