Trading Update

ProPhotonix Limited (London Stock Exchange - AIM: PPIX, OTC: STKR), a high technology designer and manufacturer of LED illumination systems and laser diode modules, with operations in Ireland and the United Kingdom, today announces a trading update for the 2019 fiscal year.

Trading conditions remain challenging and the Board currently expects Group revenue for the year ending December 31, 2019 will not likely exceed the 2018 full year ($16.4 million). Trading has been inconsistent across our customer base due to product introduction delays and the current business climate.

Tim Losik, CEO, commented:

"Our strategy, to support our significant OEM customer base and to make continued investments in new product introductions, remains a priority for the Board. We continue to invest in production and technical capability as we take on new customers and develop products. These investments, which will occur in advance of realized revenue, will allow us to complete the production build out necessary for OEM and UV LED products.

We continue to see an inconsistency in customer order behavior in 2019 - with customers both falling below and exceeding our budgeted projections. Second half revenue is still unclear and whilst the Board considers it conservative, it is right to provide this guidance to the market given these current uncertainties. Measures are underway to partially mitigate the effect of the revenue profile to shore up cash flow. We remain optimistic about the future of the business as we build our OEM partnerships along with a comprehensive portfolio of products."
