Private equity buyouts

Within: Private equity buyouts

Kirkland & Ellis LLP’s inexorable rise continues. The firm has retained its core client base of big names such as Madison Dearborn and Bain Capital, while developing tighter relationships with the likes of Blackstone, KKR, Cerberus Capital Management, Thomas H Lee Partners and TPG. The firm established a Boston office in 2017 with a series of key partner relocations and several lateral hires, including private equity specialist Matthew Cohn from Weil, Gotshal & Manges LLP. This follows a number of recent lateral recruits in New York and Houston, two key private equity locations. The ‘top-echelon and pre-eminent law firm’ is the ‘crème de la crème’ and is commended for its oil and gas expertise thanks to its ‘unmatched knowledge and transaction expertise’. The ‘commercial’ team ‘can work faster than anyone without forgoing work quality’. In 2017, the firm advised anchor client Bain Capital on a $3.2bn carve-out acquisition from Sealed Air of its Diversey Care division and the food hygiene and cleaning business of its Food Care division. It also advised Blackstone on its $4.8bn acquisition of Aon’s technology-enabled benefits and human resources platform and its $6.1bn acquisition of TeamHealth Holdings. Beyond these large cap-deals, the firm also operates a market-leading mid-market practice. Notable partners include Jon Ballis, Sanford Perl, Matthew Steinmetz, Richard Campbell and New York’s Eunu Chun. Stephen Ritchie and Walter Holzer are ‘extremely practical and business minded’, they ‘consider the upside of every obstacle’ and are ‘very problem solving and creative’. New York’s Peter Martelli has played a key role in cementing the firm’s connection to Blackstone and Andrew Calder is a star performer in Houston. New York-based Michael Weisser and Leo Greenberg are also prominent names, Jeremy Lissis a rare M&A attorney with the ability to cut across multiple practice areas and solve problems’, and Corey Fox is a ‘super star’ whose ‘personal skills set him apart’. Jeffrey Seifman is ‘straightforward, cuts through the nonsense and is able to build consensus on very complex matters’. Steven Napolitano and Brendan Head joined from DLA Piper LLP (US) in May 2018. Attorneys are based in Chicago unless stated otherwise.
