Dollar Tree’s decade-long effort to fold the Family Dollar chain into its business is ending after agreeing to sell the bargain store chain to a pair of private equity firms for $1 billion. Dollar Tree Inc. bought Family Dollar with its over 7,000 stores ten years ago for more than $8 billion.

Analysts cite a number of reasons for Family Dollar’s difficulties, including low-income shoppers who are wrestling with inflation, competition with other retailers, and issues including poorly maintained stores.

Dollar Tree is selling its Family Dollar business at a discount. A decade after buying the 66-year-old business, Family Dollar, for $8.81 billion and absorbing the chain's locations, Dollar Tree is agreeing to the chain being acquired by the private equity firms Brigade Capital Management and Macellum Capital Management for just over $1 billion.
