Between 1988 and 2015, Family Dollar Stores made an average annual profit of $182.9 million, according to data from S&P Global Market Intelligence. But those days are long gone since the 2015 acquisition by Dollar Tree.

Last week, Dollar Tree announced a "review of strategic alternatives" for Family Dollar.

"Last year, we announced a comprehensive review of the Family Dollar portfolio, including the planned closure of approximately 970 underperforming Family Dollar stores to focus on enhanced investments in remaining Family Dollar stores that present favorable opportunities for long-term growth and transformation, with more attractive returns on capital," Rick Dreiling, Dollar Tree chairman and chief executive officer, said in prepared remarks. The company said that it was "beginning to see progress" while trying to "grow the Dollar Tree banner through compelling initiatives like our expanded multi-price offerings, significant planned new store openings across the United States" and acquisition of 170 stores from 99 Cents Only.
