Linked Reviews
Financial and corporate
Mason Hayes & Curran is a Dublin-based firm with additional offices in London, San Francisco and New York.

 

Highlights 


The firm acted as Irish counsel to Carlyle on its acquisition of Vantive Health, Baxter International's renal care business, as part of one of the largest leveraged finance transactions in the market during 2025. The cross border deal involved the acquisition of US and international entities and formed a key part of Carlyle's strategy to expand its medtech portfolio.

Another highlight includes acting for Export Development Canada (EDC) and CJF Aviation DAC, the largest aircraft lessors to CityJet, in one of Ireland's most significant restructurings of 2025. The case was notable for addressing newly introduced provisions under Ireland’s preventive restructuring regime, including the application of the best-interest-of-creditors test.
