The ‘top-notch’ group at Sullivan & Cromwell LLP is ‘excellent in every respect’, exhibiting a ‘business-friendly approach’, and ‘very deep bench’. The firm sits comfortably at the top of the market globally, which also ensures it is regularly involved in some of the most prominent cross-border matters. Most notably, the New York office teamed up with the London office to advise Anheuser-Busch InBev Finance on its $46bn offering of notes as well as on its subsequent $1.4bn offering of notes; the initial transaction was notable for being the second-largest corporate bond sale on record and the US side of the deal was led by Frank Aquila. Among its work for underwriters, Robert Risoleo assisted Citigroup Global Markets and UBS Securities with Aetna’s $13bn notes offering, while Los Angeles-based Patrick Brown advised the underwriters on two offerings of notes by AT&T totaling $10bn. Robert Downes and Catherine Clarkin are also highly regarded. Named partners are based in New York unless otherwise stated.
