Kenneth Wallach – Simpson Thacher & Bartlett LLP

Simpson Thacher & Bartlett LLP is consistently at the forefront of the high-yield debt market, both for issuers and underwriters. The high-yield practice is rated for standalone transactions and those as part of leveraged financings, which is a particular forte for them. The firm advised on well over 100 high-yield deals in both 2020 and 2021; it achieves this volume of deals despite having a relatively small senior-bench compared to its natural competitors. Along with its prestigious underwriter client base, its swathe of private equity clients and their portfolio companies, the firm is also recognised for its regular engagements in deals involving first-time issuers. It has also made an impression in ESG and sustainability-linked financings. The firm is further noted for advising on deals involving high-yield issuers that are looking to achieve investment grade status. Roxane Reardon is a rounded debt capital markets specialist with an especially strong record in underwriter engagements. Kenneth Wallach is rated for private equity-related deals and transactions in the technology sector. Both are based in New York. The lauded Arthur Robinson has stepped down as global head of capital markets.

United States > Finance > Capital markets: equity offerings

Simpson Thacher & Bartlett LLP has a well-rounded and high-end equity offerings practice, driven by a balanced mix of investment bank, private equity sponsor and general corporate clients. The firm has gained further traction in SPAC IPOs and de-SPAC transactions. With its history in private equity, the firm has really benefitted from the trend of private equity sponsors taking their portfolio companies public. The firm has made further progress in representing tech companies and unicorns, thanks in part to the success of its Palo Alto office and the activities of its esteemed private equity clients such as Silver Lake Partners and Blackstone. A team led by leading equity capital markets specialist Joshua Ford Bonnie  advised Blackstone portfolio company Bumble on its headline $2.5bn IPO. Kenneth Wallach also has an excellent record in novel transactions, including for regular client Silver Lake Partners. Joseph Kaufman and Roxane Reardon are highly rated, along with Ryan Bekkerus. William Brentani and Kevin Kennedy are key names in Palo Alto. All named individuals are based in New York unless stated otherwise.
