ProPhotonix Limited provided earnings guidance for the first half and full year 2018. For the first half, the company revenue is expected to be approximately $8.8 million, an increase of 4% over the 2017 comparable figure first half 2017: $8.5 million. Increased revenue was generated from higher sales to several major customers, although this was less than internal company expectations.  These gains were partly offset by a decrease in sales from one large customer that converted to an alternate technology in the second quarter of 2017. Finally, the first half revenue was impacted by delayed shipments of products valued at approximately $0.5 million that had been expected to be recognized in first half -2018 but will instead be recognized in second half -2018. A competitive market environment, revenue mix and higher component costs have contributed to gross profit margins declining to approximately 39% in first half -2018 (first half-2017: 44%). Higher SG&A expenses, mainly in respect of stock based compensation expense, have adversely impacted the operating and net income for firs half-2018 as compared to first half-2017. Operating loss (unaudited) for first half -2018 is expected to be approximately $0.5 million, first half -2017: $0.6 million profit.  Earnings before interest, taxes, depreciation, amortization, and stock-based compensation (adjusted EBITDA) for first half -2018 are expected to be approximately $0.2 million (unaudited), compared to $0.7 million in first half -2017. The board currently expects full year 2018 revenue of approximately $19.0 million, gross profit margin at approximately 41%, adjusted EBITDA of between $1.25 and $1.50 million, and net income of break-even.
