Can someone explain to me how income is distributed among stockholders?

A company may sell part of its ownership to outside investors (shareholders) in the form of stocks. However, as a result of half their company being owned by stockholders, I'm guessing half of their earnings needs to be split among the stockholders. However, this is not the case I observe. In most cases barely any dividend or annuity is paid. Can anyone explain to me this discrepancy?
