SOUTH JORDAN, Utah, April 25, 2013 (GLOBE NEWSWIRE) -- Merit Medical Systems, Inc. (Nasdaq:MMSI), a leading manufacturer and marketer of proprietary disposable devices used primarily in cardiology, radiology and endoscopy, today announced record sales of $103.9 million for the quarter ended March 31, 2013, an increase of 9% over sales of $95.6 million for the quarter ended March 31, 2012. Merit's non-GAAP net income for the quarter ended March 31, 2013, was $4.3 million, or $0.10 per share, compared to $7.2 million, or $0.17 per share, for the quarter ended March 31, 2012. GAAP net income for the first quarter of 2013 was $671,000, or $0.02 per share, compared to net income of $5.7 million, or $0.14 per share, for the first quarter of 2012. The decrease in GAAP net income was attributable primarily to lower gross margins, higher investments in research and development, and increased interest expense. For the first quarter of 2013, compared to the first quarter of 2012, catheter sales grew 10%; custom kit and tray sales were up 7%; Endotek sales increased 6%; stand-alone device sales rose 2%; BioSphere sales decreased 5%; and inflation device sales decreased 5%. Excluding lower sales to an OEM customer, inflation device sales rose 1%. Gross margins for the first quarter of 2013 were 41.4% of sales, compared to 46.2% of sales for the first quarter of 2012. The reduction in gross margins was due to higher standard costs of 1.9% of sales resulting from lower production volumes for the first quarter of 2013, amortization of developed technology costs of 1.3% of sales associated with the integration of the operations of Thomas Medical Products, Inc. ("Thomas Medical"), implementation of the Medical Device Excise Tax of 1.0% of sales which was part of the Affordable Care Act, and one-time finished goods inventory mark-up costs of 0.6% of sales related to the Thomas Medical acquisition. Excluding the non-recurring Thomas Medical finished goods inventory mark-up costs, gross margins would have been 42.0% of sales for the first quarter of 2013. The non-GAAP gross margin was 44.4% of sales for the quarter ended March 31, 2013, compared to 47.2% of sales for the quarter ended March 31, 2012.
