Macys has warned customers it will be “working with our supplier partners to help mitigate the impact of the crash on our customers and business”.
The company said the loss of sales to the Australian market and to China, where it is based, was the result of “some challenging trading conditions”.
“We continue to work with our suppliers to assess the impact on our clients and business,” a statement said.
The company also said the impact was likely to be more severe than expected because of the “shortening” of the Chinese trading season.
AppleInsider reported earlier this month that Macys had lost $9.7 million in sales in September, and the company has lost more than $6.5 billion since its IPO in 2006.
AppleInsiders reported the company had $2.3 billion in cash on hand as of March 31, down from $5.6 billion as of the same date last year.
