Gallagher, Chairman and Chief Executive Officer of MIH. “I would also like to thank and congratulate Barbara J. Comly, General Counsel of MIH, and her entire legal team on the efficiency with which they were able to formally file MIAX PEARL’s Form 1 Application in August and obtain approval from the SEC. For MIH to receive approval in the timeframe that we did after the publication of the Form 1 in the Federal Register on September 14th is a remarkable accomplishment.”

Comly, Executive Vice President and General Counsel of MIH. “We would like to thank Chair White and all of the SEC Commissioners and Commission Staff for their support and vote of confidence in the launch of MIAX PEARL.”

Schafer, Jr., Executive Vice President and Chief Informational Officer of MIH, “As price-time exchanges continue to execute increased U.S. options market volume, we are confident that MIAX PEARL will help to create better markets in this sector of the market while at the same time continuing to provide the same outstanding trading experience that our MIAX Member firms have come to expect with us.
