So AddValue Tech just released its FY15 result. As a company, it looks pretty mediocre/weak.

Comparing its first 6 months after IsatHub's launch in Oct 14, to previous comparable 6 months, the total sales of the company is up USD 1.3mil, vs. WRR up AUD 3.1m (H1 fy15 vs. H1 fy14). Without further breakdown, it's hard to tell much out of this regarding Hub's sale. It did mention "teething problems" in new product production. No clear indication from Inmarsat Q1 report either on Hub sales momentum. The name only came up once in the whole Q1 conference call as a new product.
As I mentioned elsewhere, the next announcement I am anticipating from WRR is a further Go! order. Iridium might also make a news release upon the product anniversary in June/July.
