Our Corporate and M&A Group is the largest Group in the firm and, combined with the strength and depth of the firm’s specialist departments, advises on highly complex and innovative transactions.  We have been, and continue to be, involved in most large Irish M&A transactions and most of the major flotations of Irish companies.

We advise clients on public and private M&A, migrations, reorganisations and spin-outs, joint ventures, and corporate governance. We have also advised on a large number of complex private equity transactions, acting for Irish and international equity sponsors, lenders, companies raising capital and management teams.  Our experience extends beyond transactional work and we also look after our clients through every stage of the company life-cycle.

Constant innovation allows us to service our clients in the best possible way – we pride ourselves on being the first to devise and implement new structures for Irish companies.
