First quarter 2014 revenue of $6.0 million increased $0.4 million, or 6.9%, compared with the first quarter of 2013. Higher sales reflect the success of Micron Products’ precision-machined orthopedic implants, as well as $250K in sales of Predictor^® licenses, the Company’s proprietary and customizable signal-averaging electrocardiography (SAECG) software used to help assess a patient’s risk of certain heart arrhythmias.

Gross profit grew 38% to $1.3 million, or 21.7% of sales. Expanded gross margin resulted from the significant operating leverage gained on increased volume of machined orthopedic implants and sensors, as well as a lower cost of goods sold associated with Predictor license revenue. Last year’s first quarter gross profit was $952 thousand, or 16.9% of sales.

Moderately higher selling and marketing expenses of $0.1 million reflect the Company’s strategy to grow sales of its higher margin, precision-machined orthopedic implants and other customer specific proprietary technologies for the military, law enforcement and automotive industries.

During the first quarter of 2014, the Company's general and administrative expenses declined
$0.1 million to 9.9% of sales compared with 12.8% of sales for the same period last year.

Research and development (R&D) expenses for the quarter increased $37,425 to $96,827, or 1.6% of sales, up from $59,402, or 1.1% of sales, last year.

“We are committed to the development of new products for the medical device, military and law enforcement industries. We believe that our R&D investments will drive future growth,” added Mr. Emma.

Interest expense increased $59,601 to $70,149 over the prior-year period as a result of the Company’s new credit facility, which it entered into in March 2013, and the subordinated promissory notes, which the Company entered into in December 2013.

Net income increased $262,388 to $256,717. On a diluted per share basis, earnings were $0.09 per share, measurably improved over break-even in the same period last year.

Mr. Emma concluded, “We are transforming Micron Products by exploiting our engineering design and manufacturing expertise to capture opportunities to diversify our products and customers. We are anticipating new sales potential combined with profitable, efficient operations. We are highly optimistic about our future and believe we are strategically positioned for growth over the long term.”
