why after an announcment does the sp drop?, page-11

No I think it's the fact that they only let the market know of the error in forecasting revenue in the half yearly results.
As this accounting practice would have been implemented prior to the beginning of the FY - they had ample time to update the market (well their accountants should have known about it!!).....SH's would be alot more forgiving if known earlier.

In saying that....i think they'll hit the 6million in revenue no problem....with 2.3million in H1 and the expectation that majority of the revenue would be in the back half of the FY I can't see them not hitting the revised target - especially if the UWS contract goes according to plan.
