The virus has upended the retail industry as shoppers stay home to avoid catching the highly contagious illness and stores remain shut.

Mastercard Inc, Visa Inc and PayPal Holdings Inc have also warned of slowing revenue growth due to the outbreak.

American Express said it now expects revenue growth to be in the range of 2% to 4% on a constant currency basis and adjusted earnings per share in the range of $1.90 to $2.10, excluding reserve builds in the first quarter.

This compares to analysts' average estimate of a $2.17 per share profit and revenue growth of about 8%, according to IBES data from Refinitiv.

American Express said it was not able to forecast its future financial results beyond the first quarter at this time, citing ongoing uncertainty surrounding the duration, magnitude and geographic reach of the coronavirus pandemic.
