There is a clue in the 2020 Financials DB 2020
Post# of 7805
2020 had $829k in Sales with a Cost of Goods $323k.
That equals a 61% Margin with roughly 37% of Sales being Retail and 63% being OEM as this was a transition year.
In 2019 the Margin was 56% with all sales being Retail.
Things get real interesting when BIEL is giving orders of 1 million devices to their manufacturer instead of 100k orders.
There is a volume discount in manufacturing, so each unit cost less to make. OEM will bring a big jump in volume with every device costing less to make.
Major $$$$ flowing to BIEL when the OEM Machine picks up speed with KT, DJO, and SAI entering full Launch Mode.
