Nanosys started in 2001, and withdrew from an IPO in 2004 (shares $15-17) because they had no product or revenue. In 2015, their CEO Hartlove said that their revenue was $29.4 MM. I would estimate today they are between $50-100MM in revenue. Here is Nanosys on Wikipedia .

They never fulfilled their investors' goal to go public. Sixteen years is a long time, about twice as long as the longest QMC investors. At some point the investors want to cash out, if not for the gold at the IPO rainbow, than to recoup their money back, at least.

FWIW-

That's what I hear from a friend back east is happening today.
Nanosys has placed itself on the market for $1Billion for the Investment/Management/Banks/Brokers to sell. My friend is in
the Display Industry at a level with ties to the investment banker
world, and I trust him or would not put out this rumor.

Last I heard, Nanosys can make 20000Kg of quantum dot concentrate,
which Jeff Yurek once told me means a 10% load of QD, or 2000Kg QD.
That's about what QMC can do too.

So, if you give QMC the same valuation, $1Billion, / 400m shares = $2.5 per share.
That is 20 times today's share price. FYI.
