Remember that this is just an option to buy, the actual amount required to buy is most likely more then $1 million, up to $4 million. SRSR/Nio-star would have needed to earn/ forecasted to earn, $70 million + before it made sense to buy out this option (after ~$70 million they would be paying out more then it would cost them just to buy it out). At that point do they care about 1.5% ?
Obviously if this all goes as planned, whomever bought that option could make millions. ... If all goes as planned, someone whom invests $175k in SRSR stock this year could also make millions.
