Cirsa operates casinos and gambling platforms in Spain – where it is the largest casino operator – Italy and Morocco, as well as in Latin America. It entered Portugal and Puerto Rico last year.
The maximum offering size, including the over-allotment option, which if exercised in full would take the free float to 20.7%, was set at 521 million euros, or 34.8 million shares, the company said in a regulatory filing.
Cirsa expects its shares to be listed and start trading on the Spanish stock market on July 9.
