Dialight plc ("Dialight" or the "Group")

Trading Update

As reported in the 2013 interim results, the timing of the award of major Obstruction System contracts remains difficult to predict. Since the interim results, the Group has announced one contract for Obstruction Systems and has made good progress towards qualification and award of other significant Obstruction System business. However, the Group does not expect these contracts to be awarded in time to sufficiently impact the current financial year. This is likely to negatively affect the Group's expectations for overall financial performance in 2013.

The Lighting segment continues to grow very strongly with no change in guidance for both the short and long term.

The delay in contract awards for Obstruction Systems means that the Group's expectations for overall profitability are likely to be broadly in line with the prior year.
