FOR THE QUARTER ENDED MARCH 31, 2011

SOUTH JORDAN, UTAH— 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 $86.6 million for the quarter ended March 31, 2011, an increase of 28.5% over sales of $67.4 million for the first quarter of 2010.

Merit’s non-GAAP net income for the quarter ended March 31, 2011, adjusted to eliminate non-recurring costs attributable to Merit’s acquisition of BioSphere Medical, Inc., and amortization of intangible assets, was $7.9 million, or $0.27 per share, up 51% compared to the quarter ended March 31, 2010.  The non-recurring acquisition costs attributable to the BioSphere acquisition include legal, accounting and stepped-up inventory costs of $291,000, net of tax, for the quarter ended March 31, 2011.

GAAP net income for the first quarter of 2011 was a record $6.6 million, or $0.23 per share, up 47% compared to net income of $4.5 million, or $0.16 per share, for the first quarter of 2010.

Gross margin for the first quarter of 2011 was 45.9% of sales, up 370 basis points, compared to 42.2% of sales for the first quarter of 2010, primarily due to the sale of new, higher-margin BioSphere products and increased direct sales in China.  Merit’s gross margin would have been 46.4% of sales, up 420 basis points, excluding the one-time acquired BioSphere inventory mark-up costs of $404,000 for the quarter ended March 31, 2011.

Income from operations for the quarter ended March 31, 2011 was a record $10.2 million, or 11.8% of sales, up 61% compared to $6.3 million, or 9.4% of sales, for the first quarter of 2010.  The increase was primarily attributable to increased sales combined with improved gross margins.

“The business is growing in all geographic regions and all product groups,” said Fred P. Lampropoulos, Merit’s Chairman and Chief Executive Officer.  “We believe the investments we have made over the past few years are paying off.  Our acquisitions are providing best-in-class products as well as the pull-through of other core products.”

“In the past few weeks, we have received FDA approval for Merit’s ASAP™ Thrombus Removal Catheter, as well as two new product approvals in China.  In the next few weeks we expect to launch several new products including the Big60™ Inflation Device,” Lampropoulos continued.  “We thank our employees who produced and delivered $32.7 million of sales in March.”

Selling, general and administrative expenses for the first quarter of 2011 were 28.4% of sales, compared to 28.2% of sales for the first quarter of 2010.  Non-GAAP SG&A expenses, excluding one-time BioSphere acquisition costs, would have been 28.3% of sales for the quarter ended March 31, 2011, compared to 30.7% of sales for the fourth quarter of 2010, a sequential improvement of 240 basis points.

Research and development costs were 5.8% of sales for the first quarter of 2011, compared to 4.5% of sales for the first quarter of 2010, primarily due to the addition of the BioSphere R&D group and its projects, as well as Endotek stent development.

For the first quarter of 2011, compared to the first quarter of 2010, catheter sales increased 22%; inflation device sales grew 19%; stand-alone device sales rose 16%; custom kit and tray sales were up 16%; and Endotek sales increased 9%.  BioSphere sales contributed $7.7 million, or 11.3%, to Merit’s sales for the quarter ended March 31, 2011.  Merit’s core business, which excludes BioSphere revenues, was up 17.2% for the quarter ended March 31, 2011, compared to the first quarter of 2010.
