Twitter Co-Founder and Chairman and Square CEO Jack Dorsey speaks onstage during 'From 7 Dwarves to 140 Characters' at the Vanity Fair New Establishment Summit at Yerba Buena Center for the Arts on October 9, 2014 in San Francisco, California.
The IPO is expected to raise up to $403.7 million, the company said in a regulatory filing.
As Dan Primack points out in Fortune, this would actually place Square at a lower valuation than its most recent funding round, where the company raised $150 million at a $6 billion valuation.
Primack notes that this last private round priced the stock at roughly $15.5 per share.
Square is headed by Twitter Inc chief executive, Jack Dorsey.
