First Quarter 2017 Financial Results

Revenue was $1.4 million for the quarter ended March 31, 2017.  This amount includes $0.9 million for medical device and service revenue and $0.5 million for industrial sales. Revenue was $8.5 million for the quarter ended March 31, 2016.  This amount included $6.5 million of previously deferred revenue that was recognized as a result of a change of an accounting estimate, and $0.4 million of engineering services revenue.

Gross profit for the quarter ended March 31, 2017 of $0.4 million was primarily derived from device and related revenue. This amount reflects a gross profit of $0.2 million from medical device sales and $0.2 million from industrial sales. This compares to a gross profit of $1.5 million for the first quarter of 2016, which included $2.4 million resulting from the change of an accounting estimate.

Sales and marketing expenses were $3.1 million in the first quarter of 2017 compared to $2.5 million in the first quarter of 2016, an increase of $0.6 million. This increase was primarily due to increased clinical research for the medical business and activities supporting our industrial products.

Research and development expenses were $2.9 million in the first quarter of 2017 compared to $2.1 million in the first quarter of 2016, an increase of $0.7 million. This increase was primarily due to internal development efforts for our next generation home mobility and industrial products.

General and administrative expenses were $2.6 million in the first quarter of 2017 compared to $3.5 million in the first quarter of 2016, a decrease of $0.9 million.  This decrease was primarily caused by charges in 2016 related to the departure of a former CEO without comparable amounts in 2017.

Cash was $9.4 million as of March 31, 2017 compared to $12.3 million as of March 31, 2016.  Cash outflow from operations in the first quarter of 2017 was $7.3 million.  In April 2017, we completed a financing, raising approximately 11.7 million for working capital and general corporate purposes.
