From what I know about dilutions, is that they usually happen when there is a secondary offering of the stock, (i.e. the company sells more shares to raise more money for a project or acquisition.) The dilution statement may refer to the current equity holders. Is the company publically trading on an exchange outside of the US? either way there may be investors (if they company has really not been taken public, then their shares are not publically traded, but may still exist... think Venture Capitalists and Angel Investors.)
my second point is that when they do the IPO pricing for $24-$26 range, expect it to open at $30-$33 on the first day of trading. The only way you can get-in on the IPO price is if you open an account with one of the underwriters (usually GS, MS, CS have good records -- the stocks they take public do rather well) but what happens to the price after the IPO week is uncertain.
my third point is that the Ag stocks have had their run, now is not the time to play catch-up. My play would be to wait until they are falling down, and play them on the short side.
Good luck, I hope this helps!
