More misinformation - VEND manufacturing relationships are so-so, and there will not be 2 manufacturing lines.
VEND hinted at this in an earlier announcement, but its latest 10-Q makes it clear - They are not going to have multiple kiosk suppliers, at least not beyond a transition period. They are hoping to (no final contract has yet been announced) make arrangements to have Stoelting manufacture the kiosk, and FLEX will be around only for a transition period while Stoelting picks up.
This makes some sense given the horrible performance thus far by FLEX. The 10-Q also noted that 34 kiosks had to be removed from service in February and March, bringing the total in actual use down to 186 as of March 31.
So, FLEX will be winding down, while Stoelting will be winding up. It seems to me that any predictions regarding expected deliveries in the second half of 2019 are only slightly better than speculation.
