Underwriter-side specialist Cahill Gordon & Reindel LLP has steadily expanded its debt capital markets capabilities. Although it is best known for its top-tier high-yield debt capability, the firm’s ‘excellent relationships with investment banks’ and ‘very prominent lawyers’ have developed into a broad standalone investment grade debt practice. Of particular note, the firm advised the underwriters on Comcast’s twelve-tranche public offering of $27bn in new debt financing to fund its acquisition of Sky; the deal, which represented the fourth-largest bond sale to date, was led by William Hartnett. In another highlight, a team led by Timothy Howell, John Tripodoro and Corey Wright advised the underwriters on a $2.5bn notes offering by Charter Communications Operating LLC and Charter Communications Operating Capital. Other senior names in the New York-based group include James Clark, Jonathan Schaffzin and Daniel Zubkoff.

Of late, William Hartnett advised the underwriters on PlayAGS’ $164m IPO, and also advised the underwriters on two secondary offerings of PlayAGS’ common stock totaling $285.5m Other key clients include Morgan Stanley, which Jonathan Schaffzin advised on a $543.5m secondary offering of Norwegian Cruise Line shares, and Citigroup Global Markets, which Hartnett, Schaffzin and William Miller advised on Keane Investor Holdings’ $279.5m secondary offering of shares in Keane Group.

Within: Capital markets: high-yield debt offerings

‘In a league of its own’, high-yield debt heavyweight Cahill Gordon & Reindel LLP is widely acclaimed as ‘the indisputable leader in underwriter-side representations’. The New York-based group, which is admired by peers for its ‘excellent relationships with all the major banks’, ranked top in 2018 for manager-side mandates in the high-yield debt space by both deal value and deal count. Among its highlights, William Hartnett advised the initial purchasers on a string of offerings by Valeant Pharmaceuticals totaling $4.7bn, while Jonathan Schaffzin paired up with William Miller to act for the underwriters on three offerings by Equinix worth a combined €2.7bn. The firm is also widely recognized for its ‘dominant position in the LBO market’. In a recent headline on that front, the firm advised the initial purchasers and lead arrangers on over $13bn in financings to back Blackstone Group’s acquisition of a 55% stake in Refinitiv, which was one of the largest non-investment grade leveraged buyouts completed since the financial crisis — James Clark, Daniel Zubkoff and Corey Wright led that transaction. Other highly regarded senior specialists are Douglas Horowitz and John Tripodoro. The group also includes up-and-coming names Marc Lashbrook and Joshua Zelig and rising star Meghan McDermott.
