"This domestic giant is applauded for its formidable corporate practice, which excels in all aspects of the area."
Chambers Europe

Matheson’s Corporate Group is one of the leading practices in Ireland. Our lawyers are consistently chosen to advise on the most significant corporate transactions involving Irish and international companies.

We advise on the full range of domestic and international corporate transactions, including mergers and acquisitions, joint ventures, corporate restructurings, private equity, IPOs and other equity capital markets transactions.

Our International Business team provides a full range of Irish corporate law advice and services to overseas clients doing business in and through Ireland. This team has a particular focus on inward investment, cross-border re-organisations and integration projects.

We have advised the bidder on more cross-border deals involving Ireland than any other law firm in the last ten years (Mergermarket September 2017).

Matheson was named Ireland M&A Legal Adviser of Year at the 2017 Mergermarket European M&A Awards.
