First Quarter 2017 Financial Results

Net sales rose 55% in the first quarter of 2017 to $35.9 million, compared to $23.1 million in the same period in 2016.  The growth reflected primarily strong unit volume increases and expansion of the company’s direct sales operations into new international markets.

Operating expenses for the first quarter of 2017 were $30.4 million, up 57% compared to $19.4 million in the same period of 2016.  The increase reflected primarily the company’s ongoing investment in, and expansion of, its global infrastructure by adding international sales operations and increasing domestic sales, marketing and administrative personnel and expenses.

Income from operations was $0.3 million in the first quarter of 2017, compared to $0.6 million in the first quarter of 2016.  Net income in the first quarter of 2017 was $0.9 million, or $0.02 per diluted share, compared to $0.9 million, or $0.03 per diluted share, in the first quarter of 2016.

2017 Revenue Guidance
