11.00am: ProPhotonix shares dim as it swings to first-half loss and warns on outlook 

ProPhotonix Limited (LON:PPIX) shares dimmed by 32.5% to 2.12p after the maker of LED illumination systems and laser diode modules swung to a first-half loss.

The group made an adjusted earnings (EBITDA) loss of US$0.5mln in the six months to 30 June, compared to a profit of US$0.2mln last year, as revenue fell 18.9% to US$7.2mln.

“Revenues in the first half of 2019 were down 18.9% primarily due to a decrease in laser and diode product sales (including the decline of $0.9mln from the largest customer due to a delay in a new product launch) partially offset by a small net increase in LED product sales,” said chief executive Tim Losik.

He added: “Currently, we are not able to accurately estimate full year sales, but the board currently envisage they will be no more than US$15.0mln.

“We are now forecasting revenues in the second half will broadly approximate those achieved in the first half.”

He said the company expects to continue to be loss-making and is now reviewing all funding and strategic options available to ensure short-term working capital needs are met.
