Princeton, NJ – August 22, 2013 – The MIAX Options Exchange (“MIAX” or the “Exchange”) announced today that it anticipates implementing an equity rights program for Exchange members (the “Program”). Under the Program, participating Exchange members would be issued units representing the right to acquire equity in the MIAX’s parent holding company, Miami International Holdings, Inc., in exchange for a cash payment and the achievement of certain volume thresholds on the Exchange over a 23 month period. The purpose of the Program is to promote the long-term interests of MIAX by providing incentives designed to encourage MIAX market participants to contribute to the growth and success of MIAX, by being active liquidity providers and takers to provide enhanced levels of trading volume to MIAX’s market, through an opportunity to increase their proprietary interests in MIAX’s enterprise value. The implementation of the Program remains subject to review by the Securities and Exchange Commission and the publishing of a Form 19b-4 filing for notice and comment.

Thomas P. Gallagher, MIAX’s Chairman and Chief Executive Officer said, “As of today, a number of Exchange members have expressed strong interest in participating in the Program. In addition, the Program is open to all MIAX market participants generally.” Continued Gallagher, “The implementation of this Program is part of the Exchange’s overall business strategy to create a compelling trading venue and increase its market share in the U.S. equity options space. We are looking forward to the completion of this next major milestone in the development of MIAX as the Exchange approaches its 4 th operating quarter since launch in December 2012.”
