Jrai,  Actually the company does have to let the investors.  If it is of significence to the company and they hold back information from the stock holders, thay can get in a real world of hurt.  It is like having drill results, good or bad, at some point that is resonable, you need to release information.  If you were to go look at actions from the BCSC, you would see that not reporting material information is a major part of what the BCSC nails companies on.  They really get busted when insiders trade before news annoncement.
