This is 15 per cent more that what the Dunkin’ Brands group initially planned in raising when it announced two months ago that it would take part of the company public and sell at least $400m of stock.
The funds raised from selling the shares will be used to reduce about $475 million in debt, notes the SEC filing.
The private equity owners, comprising three investor houses, will each retain a 26.1 per cent controlling interest.
Investors Bain Capital, Carlyle Group and Thomas H Lee Partners acquired Dunkin’ Brands for $2.4bn from Pernod Ricard in 2006.
The business, which operates through a franchise system, consists of four segments: Dunkin’ Donuts US, Dunkin’ Donuts International, Baskin-Robbins International and Baskin-Robbins US.
In 2010, the company reports that its Dunkin’ Donuts segments generated revenues of $416.5m, or 76 per cent of its total segment revenues, of which $402.4m was in US generated, and $14.1m was internationally derived.
