ProPhotonix Limited provided earnings guidance for the first half of 2017. The company announced that Revenue for the first half 2017 is expected to be approximately $8.3 million, an increase of 4% over the 2016 comparable figure. The revenue growth stems from an increase in sales to several major customers, partially offset by a decrease in sales to one large customer that converted to an alternate technology in the second quarter of 2017. Operating income for the first half 2017 is expected to be approximately $500,000, a decrease of approximately $245,000 versus the 2016 comparable figure. The reduction in operating income results is a reflection of the investment the Company is making for the future growth of the business and from increased sales expenses from the hiring of additional staff in the fourth quarter of 2016, increased engineering and development costs associated with several large original equipment manufacturing (OEM) projects, and the continuing investment in the UV LED product development.
