Bain Capital, the US-based private equity group, is in the final stages of talks to acquire Skylark, the c.3,680-strong Japanese restaurant chain, from Nomura Holdings for $3.4bn (£2.18bn).

According to reports overnight, an agreement between Bain and Nomura over the deal, which will be one of the largest in Japan by a foreign firm since the start of the financial crisis, is likely to be finalised by the end of this month.

Bain, which has been linked with a bid for Domino’s Pizza in the past, previously backed Burger King as part of a consortium and currently owns Brakes Bros and part-owns Dunkin’ Brands.

Founded in 1970, Skylark operates around 3,680 restaurants in Japan and overseas.

Nomura linked up with CVC Capital Partners to acquire the then listed restaurants company for around $3.25bn in 2006.
