If I were a major brand name company and I saw a struggling greylisted company with a good product and terrible management that was on its knees with legal issues... and had an opportunity to buy it for far less than fair market value, why not?! They'd rebrand it anyway...
Seems to me that if there were ever an opportune time to buy out a patent holding competitor, this would be it.
The buyout was a buyout to take the company private (European Hedge Fund). You don't need to trade if you are taking it private. The money would be distributed to shareholders of record.
If the buyout was that imminent, you would think that the data used to sign off on a buyout would certainly be data that could satisfy the SEC. Wasn't that request made by the SEC on the 18th?
