There is an assumption implicit in this statement. The assumption is that it will require 50,000,000 shares to be sold to acheive the $250,000,000 goal.
If the share price rises above the $5 mark when the company decides to start selling shares, the number of shares drops. The higher the share price, the lower number of shares required to meet the target.
There is no evident reason for the company to start selling shares any time soon.
Good things have to happen before there is "anticipated growth" that would require that amount of money.
