I don't think that's correct. The $1.5M+ was one purchase order. According to the tweet, Walmart paid it and HearingAssist has it in their possession. The other PO is for $9M+, for a total of $11M+.
These are just purchase orders, not profit from the kiosks/displays.
This is how I understand it. Maybe, someone with a finance and/or business background can chime in.
