Matthew Reilly - Kirkland & Ellis LLP

Within: Merger control

Kirkland & Ellis LLP’s team was significantly bolstered by the hire of Matthew Reilly from Simpson Thacher & Bartlett LLP. Reilly combines substantial private practice experience with skills learned during a tenure as head of the FTC’s Merger IV division, where he led on merger investigations and litigation across a broad cross-section of industries. The firm features prominently in some of the largest and most complex transactions, with a particular strength in those involving regulated sectors. In 2016, Mark Kovner and Ian Conner had key roles in Teva Pharmaceuticals’ $40bn acquisition of Allergan’s generics business; according to the FTC, this matter involved the largest pharmaceutical divestiture consent in US history. The team handled other mandates for Micro Focus International, Danaher Corporation and Delta Airlines. Marin Boney as well as New York-based Ian John and Katherine Rocco are other notable individuals. Named attorneys are based in Washington DC except where indicated otherwise.
