Matheson LLP is at the forefront of cross-border transactions, particularly transatlantic deals; it advised Smurfit Kappa Group on its combination with US-based WestRock Company to form Smurfit Westrock. The firm continues to advise a high proportion of the Fortune 100 companies, many of the top global technology brands and a large number of the world’s leading asset managers. It remains noted for public M&A, private capital and financial institution deals. George Brady, Patrick Spicer, Brian McCloskey and David Fitzgibbon are at the pinnacle of the profession. Fergus Bolster, Madeline McDonnell and Susanne McMenamin are also key practitioners, along with Robert Barrett, Enda Garvey and the recently promoted Susan Carroll Chrysostomou.
