The detail is thin but it does confirm the continuing growth pattern. To do 4.2m in the year means that H2 will do 2.3m an increase of 25% over H1. If EBITDA is to be over 1m then H2 has to be 0.64m which is 75% up on H1, which means that the "gross margin" will have increased to 27% in H2 from 19% in H1.
Whilst it all looks good, will have to wait for the prelim numbers at the end of February before we can get the full picture. In the meanwhile I am quite happy to hold. The apparent increase in margins demonstrates the potential gearing of the model.
