... and which has been mentioned before, a vertically integrated producer and manufacturer of VRBs has a huge cost advantage. AVL does not need to up the price for VRBs because V2O5 market price and demand has rocketed, they can price this where ever they want between opex at 4$s ish, and current market or above. This is assuming you have extra V2O5 being produced above contract orders, and open market sales... no point letting it sit in a stock pile getting bigger... that will only reduce the market price anyway. This is where their leasing concept of V2O5 comes in.

Typically the most revenue does not come from initial product sales, it comes from long term support, maintenance and parts over 10+yrs. The argument that current V2O5 market price makes VRBs unviable is extremely short sighted and IMO completely incorrect.
