C&C says the deal to buy Anheuser-Busch InBev's Irish, Scottish and Northern Irish businesses is now complete.
The deal, which is worth €205m, has been approved by the company's shareholders, its workers and the Irish Competition Authority.
Under the deal, the main brand C&C is getting is Tennent's lager. It will also secure the distribution rights for global brands like Stella and Beck's as well as Budweiser in Scotland and Northern Ireland.
C&C said it believes the deal represents a 'logical' platform to develop its existing business, with potential to increase the position of its Magners cider brand outside its core UK market. It added that it is 'both strategically and financially attractive'.
