Princeton, N.J. – Feb. 6, 2017 – MIAX PEARL, the newest U.S. equity options exchange, today announced a successful launch of trading operations with the rollout of options on its first symbol, IBM. MIAX PEARL will continue listing options on IBM for its first week of trading and then begin rolling out additional symbols thereafter. MIAX PEARL is the second exchange of the MIAX exchange group following the launch of MIAX Options in December 2012 by its parent holding company Miami International Holdings, Inc. (MIH).

“The successful launch of MIAX PEARL marks a momentous occasion not only for us but also in the history of MIH, which is now the parent holding company of two U.S. equity options exchanges,” said Thomas P. Gallagher, Chairman and Chief Executive Officer of MIAX PEARL. “We are excited to be a part of the MIAX exchange group along with MIAX Options, and look forward to helping to grow our exchange group’s collective market share by establishing MIAX PEARL as one of the preeminent maker-taker exchanges in the industry. Added Gallagher, “This accomplishment would not have been possible were it not for the determination and hard work of our entire company, and I would like to specifically recognize the tremendous efforts of the members of our technology, legal, engineering, business strategy, operational, finance and accounting, and regulatory teams to ensure that MIAX PEARL launched seamlessly today.”

“We are very pleased with the results from our first day of live trading and the performance of our systems, as all reports from our member firms indicate that the capabilities of our trading platform met or exceeded their expectations,” said Douglas M. Schafer, Jr., Executive Vice President and Chief Information Officer of MIAX PEARL. “We look forward to MIAX PEARL continuing to meet the trading needs of our member firms and providing exceptional customer service while at the same time helping to create deeper market liquidity in this particular trading sector.”

Shelly Brown, Executive Vice President of Strategic Planning and Operations of MIAX PEARL, further commented, “The purpose of building and launching MIAX PEARL was to meet the changing trading needs of the industry as more volume shifted to maker-taker exchanges. The result is that we now have a MIAX exchange group consisting of two exchanges – MIAX PEARL and MIAX Options – with two different pricing structures and allocation models. This enables us to better serve the needs of the U.S. options market, and the addition of MIAX PEARL along with the recent introduction of the Complex Order System at MIAX Options provides us with access to approximately 75% of the total U.S. market volume.”
