There are other explanations too.
You generally get 80% of sales from 20% of clients. Anyone who has been in business knows this. While it may not be an exact 80% and there is always variance it pretty much is the case nearly all the time.
They will most likely get 80% of their sales from 20 % of the points of sale
Walmart did not kick them out, they are part of 6 OTC offering that has been rolled out throughout their stores, however they nor the other vendors will get equal sales across all stores. The stores vary in location demographics. What a nonsense thing to say.
Why would enyone focus an equal spend across all points of sale when that is not how sales occur.
The half yearly will be out in a couple of weeks which is an acrual based accounting report so we will have a better idea on what is being invoiced and what that flow looks like.
The last 4C tells nothing of invoicing as it is a cash based document and cannot factor any acrual earnings.
At the end of the day they still need a commercialisation deal or deals, and they need it very soon.
