One mailer said GWBU was actually something called Start Scientific whose promotion was funded by another entity called Serenity Holdings. This identity trail is now convoluted enough to turn me off and I haven't even looked at the company's financials yet. There are no financial results of note, so it doesn't matter. Reading the 10-K from 2011 doesn't tell us much about what the company does, and it clearly didn't do much of anything that year. It was nothing but a shell company until this year, according to its 8-K from April 2012.
The mailers came from The Penny Stock Hunter and The Penny Stock Pillager, two outfits that share the same P.O. Box. I hope I never hear from either one again. Of course, all hope is pointless.
Full disclosure: No position in GWBU at all.
