RE:RE:RE:GSPWSP, you can call Gensource for information on how to obtain a copy of their Registered Shareholder list, but that will only give you shareholders names registered with Gensource.
You can also jump through hoops to try get a NOBO list which is tougher and more expensive to obtain information on shareholders who hold shares through banks. (The majority of us)
Havent done it for a few years, but it cost about $2k in 2015 to get that corporate info. The public company I looked into only had about 2500 shareholders in total, where I would guess GSP has far more than that.
There is also an OBO list out there with a corporations shareholders that do not want to be known. Obviously impossible to get.
Good luck with your search..........
