Just listened to it again Turr, the others are correct, SV states clearly from 14:55 onward that POET currently owns 80% of SPX, they expect an IPO of that company by 2026/27 and said by that time they expect to own 50%, which was all part of the original agreement as I recall.
At 15:50 SV says Sanan will invest another $15M over the next 6 months which should bring the joint ownership to 50/50 since the company was originally valued at $50M, and their total investment will then be $25M.
All part of the plan...
