    Sullivan & Cromwell advises the world's leading private equity houses and other financial sponsors, sovereign wealth funds and institutional investors. Our relentless commitment to excellence means we aim to deliver creative, commercially astute, pragmatic and technically proficient advice at the highest level on every matter.

    That principle shapes how our practice works. S&C operates as a single, integrated partnership. Partners across M&A, leveraged finance, private credit, high-yield, capital markets, restructuring, tax, antitrust, regulatory and disputes work together as one team, ensuring that the advice our clients receive reflects the input of lawyers within the Firm whose experience and expertise best match the circumstances. Our deal teams are led from the top, with senior lawyers working closely with associates in lean, technology-enabled teams.

    We advise across the complete private equity lifecycle: control acquisitions, take-privates, carve-outs, growth and minority investments, consortium transactions, portfolio company matters, governance arrangements, disputes, restructurings, financings and exits. The practice spans the full spectrum of private capital, from large-cap leveraged buyouts to structured equity solutions, co-investments and bespoke governance arrangements, with deep experience in the sectors where sponsors are most active, including business services, technology, digital infrastructure, healthcare, financial services, energy transition and consumer.

    Sponsors increasingly deploy hybrid structures combining equity, debt, preferred capital, structured instruments and bespoke governance rights. In that environment, financing and creative capital solutions are central to how complex private capital transactions are structured and executed. S&C is among the few firms able to deliver M&A, financing, capital markets and restructuring advice within a single, fully integrated global team, coordinated through one senior point of contact.
