ProPhase Labs Reports Financial Results

for the Three Months Ended March 31, 2015

DOYLESTOWN, Pennsylvania – May 13, 2015.  ProPhase Labs, Inc. (NASDAQ: PRPH, www.ProPhaseLabs.com) today reported its net sales were $5.9 million for the three months ended March 31, 2015 as compared to net sales of $6.2 million for the three months ended March 31, 2014. The Company incurred a net loss for the three months ended March 31, 2015, of $1.4 million, or ($0.09) per share, compared to a net loss of $804,000, or ($0.05) per share, for the three months ended March 31, 2014.

The Company’s sales are derived principally from its over-the-counter (“OTC”) cold remedy products. As a consequence, a significant portion of our business is highly seasonal, which causes significant variations in operating results from quarter to quarter.

Results for the first quarter of 2015 compared to the first quarter of 2014 principally reflect the net effect of (i) a decrease in net sales of $311,000 principally due to the timing of customer purchases and consumer demand as a consequence of the incidence and severity of upper respiratory illnesses, respectively, (ii) an increase of $514,000 in administration costs due principally to an increase in legal and professional costs relating principally to now resolved litigation matters, offset by (iii) a decrease in sales and marketing expenses of $185,000 and (iv) a decrease in research and development expenses of $70,000.

Ted Karkus, the CEO of the Company, stated, “Our product development efforts have been largely focused on successfully leveraging the Cold-EEZE^® brand. To this end, we anticipate that two new products will be available on retail shelves in the fourth quarter of 2015 and that two additional Cold-EEZE^® branded products will be introduced to the trade in February of 2016.

Mr. Karkus added, “As previously reported, we are in the process of transitioning to a narrower lozenge package which adversely impacted our fiscal 2014 results. Although this transition is continuing into fiscal 2015, we expect that this adverse impact will be minimized going forward. Furthermore, we anticipate that our new Cold-EEZE^® product initiatives, in combination with additional in-store merchandizing programs, will help us grow revenues for fiscal 2015 and restore the positive revenue growth trends that started in fiscal 2011.”

Mr. Karkus continued, “In addition to new Cold-EEZE^® branded products, we are also continuing the process of implementing a series of development and pre-commercialization initiatives in the dietary supplement category. We are exploring various ways to introduce these new dietary supplement products to consumers which may include Direct Response TV. While no assurance can be made that our new product efforts will be successful, we continue to anticipate that one or more products in this new category will begin shipping before year end fiscal 2015. Furthermore, over time we may need to raise additional funds to support all of these strategic initiatives and to provide additional working capital.”
