Matheson Adds Five New Partners

New partners appointed across three practice groups

Matheson LLP has promoted five lawyers to partner across three different practice areas.  The appointments bring the total number of partners and tax principals in the firm to 122.

The new partners, who have already taken up their positions, have been appointed in the following practice areas; Corporate M&A; Litigation; and Tax.  Four of the new partners are based in Matheson's main office in Dublin and one is based in Matheson's London office.

2023 was another very strong one for Matheson's Corporate M&A, Litigation and Tax teams, who acted on some of the biggest and high-profile matters of the year, including advising Horizon Therapeutics plc on the completion of its $27.5 billion acquisition by Amgen Inc; Smurfit Kappa on its proposed combination with WestRock Company, valued at circa $20 billion; and Aon's $13.4 billion agreement to acquire NFP.  The tax team also won the Ireland Transfer Pricing Firm of the Year award at the International Tax Review (ITR) EMEA Tax Awards 2023.

Michael Jackson, Managing Partner of Matheson said, " We are delighted to announce the recent appointment of five new partners at Matheson.  The promotion of these highly skilled individuals further strengthens our leadership team, and reflects the continuous growth and success of the firm in many key areas".

"The addition of these lawyers to our partnership highlights Matheson's people strategy and our continuous investment in talent.  They exemplify the vast legal and technical expertise fostered at all levels in the firm.  I congratulate our new partners on their appointments and look forward to working with them in the future."
