Dollar Tree is suffering its biggest intraday drop since 2012 over the effect of tariffs.

Shares of the discount retailer fell as much as 17% Tuesday after the company reported disappointing third-quarter earnings and lowered its full-year guidance due to uncertainty around the trade war and tariffs.

For the full year, Dollar Tree expects earnings per share to be between $4.66 and $4.76, below its previous estimate of earnings between $4.90 and $5.11 per share.

It now forecasts fourth quarter earnings per share between $1.70 and $1.80, where analysts expected $1.94 per share.

Dollar Tree expects that tariffs placed on Chinese imports, if fully implemented, will boost cost of goods sold by approximately $19 million in the fourth quarter.
