Dec 4 (Reuters) - Dollar General raised its annual profit forecast after beating third-quarter earnings estimates on Thursday, banking on resilient demand at its discount stores, as well as its efforts to cut costs and reduce inventory-related damages.

Shares of the company, which also bumped up its full-year comparable sales forecast, were up about 3% premarket. The stock has risen about 45% so far this year.

A day earlier, rival Dollar Tree also raised its annual profit forecast as dollar stores attract middle- and lower-income customers in the U.S. seeking cheaper alternatives and better seasonal deals amid economic uncertainty and worries over a sluggish labor market.

Dollar General's focus on maintaining about 25% of its offering at or below the $1 price point to resonate with its core customers - households earning less than $35,000 annually - has also made the company a go-to destination.

The company projected annual earnings per share in the range of $6.30 to $6.50, compared with its earlier target of $5.80 to $6.30.

Dollar General now expects annual same-store sales to grow in the range of 2.5% to 2.7%, compared with its prior forecast of a 2.1% to 2.6% growth.

It earned a profit of $1.28 per share for the quarter ended October 31, compared with analysts' estimates of 95 cents, according to data compiled by LSEG.

The company's quarterly net sales of $10.65 billion edged past estimates of $10.64 billion.
