D&K Healthcare Resources, Inc. (NASDAQ: DKHR) reported today that due to lower gross profit margins in both the independent and regional pharmacies and national accounts trade classes, it had a net loss per diluted share of $(0.05) for the quarter ended December 31, 2004. The Company was negatively impacted by a lack of price increases by pharmaceutical manufacturers and a slower than anticipated transition from a “buy and hold” to a “fee for service” industry model.
