Dollar General CEO Todd Vasos said on Thursday that inflation continues to hurt the discounter’s customers and that the macroeconomic environment won’t improve this year.

Low-income Americans’ financial condition has gotten worse over the last year and more shoppers are going without basic necessities.

Dollar General joined a growing list of retailers warning of weak annual sales and profit, and said its consumers were struggling to afford some essentials as high inflation and economic uncertainty dent their spending power.
