Department store retailer Neiman Marcus Group Inc has posted a 67 per cent jump in earnings to $68.8 million for the latest quarter, up from $41.1m in the same period a year earlier.

The Texas-based company also reported improved revenue of $877.6m for the quarter to May 1, up from $722.9m in the year-ago period.

Same-store sales, meanwhile, rose 8.5 per cent during the three-month period.

"This performance is a result of the many initiatives we have taken over the past few years, including an intense focus on regular price sales growth, disciplined inventory management and active expense control," Neiman Marcus CEO Burton Tansky said.

Strong sellers in the company's specialty retail stores segment during the quarter included couture fashion, contemporary sportswear and women's dresses, while the direct marketing division experienced positive sales of casual sportswear.
