What Science in Sport said
Chief executive Stephen Moon said:
I am pleased to announce yet another period of substantial growth for SiS, which was in line with our expectations, and saw our revenues increase 24 per cent year-on-year.
We have invested heavily in digital marketing and product sampling during the first half, and the benefits are evident in the growth we are achieving, which we believe is significantly ahead of our market peers.
Trading is in line with market expectations and reflects the continued investment in brand awareness and growing the customer database, together with our expansion into Australia.
