Dollar Tree Inc's chief financial officer said on Wednesday that the retailer remains comfortable with the third-quarter and full-year sales and earnings forecasts it issued last month.

CFO Kevin Wampler made the comment at the company's capital markets conference, which was broadcast over the Internet.

In August, after Dollar Tree reported second-quarter results, it forecast third-quarter sales of $1.19 billion to $1.23 billion, and earnings of 58 to 64 cents per share.

It also said it expected full-year sales of $5.09 billion to $5.19 billion and full-year earnings per share of $3.10 to $3.25.

Analysts, on average, currently expect third-quarter earnings per share of 63 cents and full-year EPS of $3.26, according to Reuters Estimates.
