After less than four months of looking for a buyer, Michael's Stores Inc. agreed to be acquired by Bain Capital and the Blackstone Group in a $6-billion deal. Shareholders will receive $44 per share in cash, should the deal get approved. Both Bain Capital and Blackstone Group have been active in the recent trend that has seen dozens of retailers taken private. Bain was involved in the acquisitions of both Toys ‘R’ Us and Burlington Coat Factory. Michael's operates 900 Michael's stores, 165 Aaron Brothers sites, 11 Recollections stores and four Star Wholesale outlets.
