United-Guardian Reports Record Earnings

HAUPPAUGE, N.Y., Aug. 8, 2013 (GLOBE NEWSWIRE) -- United-Guardian, Inc. (Nasdaq:UG) reported today that net income for the second quarter of 2013 was up 12% over last year's second quarter, with earnings per share increasing from $0.26 to $0.29, resulting in the strongest second quarter in the company's history. For the first half of the year, earnings were up 20% and earnings per share increased from $0.53 to $0.63, once again reaching a new record high for the company.

Ken Globus, President of United-Guardian, stated, "We are very pleased that we have been able to continue to increase our earnings despite the fact that there was no revenue from Renacidin^® Irrigation, one of our pharmaceutical products. Renacidin has been out of stock for the past year due to manufacturing problems experienced by our supplier. While this has resulted in slightly lower sales this year, increased revenue from our personal care and medical products has more than made up for that lost income, with personal care product sales up over 9% for the quarter and 12% for the year, and medical product sales up almost 14% for the quarter and 22% for the year. Although we continue to be hopeful that Renacidin sales will resume by the end of the year, we are also continuing our development work on a new single-dose form of Renacidin that will be produced by a different supplier. We believe that this new form of Renacidin, along with our ongoing efforts to develop new and innovative personal care products, will enable us to continue to increase our revenues over the coming years."

United-Guardian is a manufacturer of cosmetic ingredients, personal and health care products, pharmaceuticals, and specialty industrial products.
