The offering price to the primary market was 27.02. The underwriters set a secondary-market sell target of 27.60, but clearly they were willing to let shares go for a few pennies less.
It's worth noting that only 37 million shares crossed yesterday. Given the rather large profit the underwriters are making, I have no doubt they are all picking up the option on the 5.5 million overallotment. Even though those are now being sold, the price is rising.
Demand for this stock is heavy. Fecund. Pendulous. Zaftig.
