The company will offer 5 million shares on on Friday, and another 750,000 Class A shares could be made available at the underwriters' discretion. Selling 5 million shares would raise $105 million and value the company at more than $700 million.

The price was originally expected to come in between $14 and $16 a share, but that was raised to a range of $17 to $19 this week.

Shake Shack applied to have its common stock listed as "SHAK" on the New York Stock Exchange.
