PRINCETON, N.J., May 2 , 2018 – MIAX PEARL™, a member of the MIAX Exchange Group along with MIAX Options® , announced today that it has closed its Equity Rights Program (ERPIV) following its entry into agreements with a number of leading order flow providers and market making MIAX PEARL member firms. Similar to the three prior Equity Rights Programs offered by MIAX Options, ERP-IV’s structure provides these MIAX PEARL member firms with the right to invest in MIAX PEARL’s parent holding company Miami International Holdings, Inc. in exchange for payment of an initial purchase price or the prepayment of certain transaction fees and the achievement of certain liquidity volume thresholds on MIAX PEARL.

MIAX PEARL member firms involved in ERP-IV include Citadel Securities, IMC, Interactive Brokers Group, Morgan Stanley & Co., Optiver US, Simplex Trading, Susquehanna Securities, Two Sigma Securities, Virtu Financial, and Wolverine Trading. This is the first time that Simplex Trading and Virtu Financial are participating in an Equity Rights Program. All other member firms have participated in one or more of the prior Equity Rights Programs.

Thomas P. Gallagher, Chairman and Chief Executive Officer of MIAX PEARL, said, “We are pleased to be launching an Equity Rights Program for MIAX PEARL and happy to report that we are fully subscribed for all of the prepaid fee units offered. ERP-IV follows in the tradition of the three Equity Rights Programs established by MIAX Options, and we look forward to it being equally as successful for MIAX PEARL. We would like to thank those member firms that previously participated in the Equity Rights Programs of MIAX Options for choosing to participate in ERP-IV and to welcome Simplex Trading and Virtu Financial as our newest partners.”

“Participating member firms were very receptive to the idea of an Equity Rights Program for MIAX PEARL following their positive experiences with those for MIAX Options,” said Shelly Brown, Executive Vice President – Strategic Planning and Business Development of MIAX PEARL. “We believe that, in light of their prior experiences, these firms’ participation in ERPIV will help to promote strong markets in the specific market segment that MIAX PEARL occupies while they continue to capitalize on the trading advantages that have become synonymous with the MIAX Exchange Group.”

Added Joseph Bracco, Senior Vice President – Head of Sales of MIAX PEARL, “ERP-IV was offered as a way to provide member firms not connected to MIAX Options due to market model preferences the ability to partner with the MIAX Exchange Group. With the launch of ERP-IV and MIAX Options’ current Equity Rights Program, ERP-III, scheduled to continue through 2 December 2020, we are confident that participants will take full advantage of the trading benefits and opportunities offered by the MIAX Exchange Group.”

Kurt M. Eckert, Partner and Head of Market Structure at Wolverine Trading and current director of both MIAX PEARL and MIAX Options, added, “Wolverine Trading is excited to be participating in the Equity Rights Program offered by MIAX PEARL and eager to capitalize on its structure. Congratulations to the MIAX PEARL team on the closing of ERP-IV.”

Sunny Khiani, Chief Executive Officer of IMC Chicago, commenting on the closing of ERP-IV stated, “MIAX PEARL has been an excellent addition to the MIAX Exchange Group and complements the allocation and pricing model of MIAX Options well. It is great to see both MIAX PEARL and MIAX Options having such an impact on the U.S. options exchange space in such a short time period.” Khiani further added, “Such growth confirms that the technology, risk protections and customer service offered by MIAX PEARL have been widely accepted by customers, and I believe that ERP-IV will accelerate this positive momentum towards MIAX PEARL.”
