rookinvestor...this "dilution" should not have been unexpected.
Obviously, they purchased SEMCO with shares. Duh! How else would they do it?
The thing that all the doomsdayers will fail to mention is that those shares weren't just dumped for a personal profit...they are theoretically an "even trade" for an asset that is now part of the company.
Assuming that all the new OS went for the acquisition of SEMCO, the key is to figure out whether the price for it was "a steal, a fair price, or overpriced".
I'm going to assume it was a fair price until I know otherwise.
IMO, like Turek said....Semco will be the biggest part of the company's growth going forward and could/should ACCELERATE the growth/value of the company.
