They can supply information to shareholders at practically zero incremental cost.
If tomorrow FBR sends out a shareholder announcement of a major development the price will move, free business and industry level press will pick it up, news will spread, the price will grow, traders come in, the price grows more, less dilution, less very stupid conversations on Hotcopper on whether a company with constrained supply should waste money on marketing.
But more importantly, as FBR starts making money, shareholders love earnings, retail and institutions take notice, price goes up, value gets reflected in price, less dilution, more working capital, more investment, more production, more profits.
Either way, information is free or close to it. Information is not marketing. Marketing has a very specific meaning and costs a lot for a company still in it's investment phase as an early start-up.
Some would want FBR to waste the limited capital we have on some stupid newspaper adds, television slots, facebook adds, blah blah blah.

People that claim FBR should spend money on marketing to shareholders to prevent or limit dilution should seriously reflect on whether they should be investing in individual stocks vs simply holding ETFs.

Not investment advice. Do your own research, etc. etc.
