$500k was earmarked for advance component purchases and manufacturing up to end of December 2019. Most original and Boost sales over the quarter would have used existing stock. So little expenditure on those imo. i reckon they have a headstart on funding the components for the first shipment of IQbuds2 Max.

And back to my original question. Can cash recieved from preoroders be expended to fund the manufacture and shipment of those preordered buds?

i think so.
