Dollar Tree acquired Family Dollar for more than $8 billion in 2015 after a bidding war with rival Dollar General, but it has had difficulty absorbing the chain.
Dollar Tree swung to a surprise fourth-quarter loss and will close nearly 1,000 stores after the discount retailer slashed the value of a rival chain it acquired almost a decade ago.
The retailer plans to close about 600 Family Dollar stores in the first half of this year and 370 Family Dollar and 30 Dollar Tree stores over the next several years.
Dollar Tree acquired Family Dollar for more than $8 billion in 2015 after a bidding war with rival Dollar General, but it has had difficulty absorbing the chain.
On Wednesday, Dollar Tree said it would record a $950 million impairment against the trade name Family Dollar, on top of a $1.07 billion goodwill charge. Family Dollar will spend more than $594 million closing or rebranding stores, essentially erasing profits from the holiday season.
