Net income increased 124% to $621,000 or $0.09 per diluted share from $277,000 or $0.04 per diluted share for the comparable quarter last year. Income from operations was $1.1 million compared to $675,000 in the comparable quarter last year.

As of March 31, 2006, NAI had cash and working capital of $1.6 million and $12.7 million, compared to $1.9 million and $14.4 million at June 30, 2005, respectively.

CEO Mark LeDoux commented, “During the third quarter we integrated previously outsourced fulfillment activities for our Dr. Cherry Pathway to Healing^® product line into RHL’s existing operation, which should generate cost savings in future periods. We are pleased with our progress related to the integration of RHL and expect to realize additional strategic and operational benefits.”

President Randell Weaver added, “During the third quarter, we invested in inventory and made substantial progress in completing orders for our two new contract manufacturing customers. Though deliveries through March 31 were limited, in April we began regular deliveries and expect to continue for the remainder of the fourth quarter. We expect consolidated net sales to exceed $33 million in the fourth quarter. We are committed to growing and strengthening the relationships with our new and existing highly valued customers.”
