Eh thats kinda hard to say. Looking at the quoted price of a stock is a little bit misleading without looking at the Bid and Ask volumes.

Currently the bid of ~1000 shares are available at 24.97 (these number will vary second to second)

That doesn't mean that all of the shares IPOed could have been sold for that price.

Was there likely money left on the table? Yes. But its pretty difficult to put a dollar amount to it.
