(Incorporated in Delaware)

We are a technology-driven leader in building and operating regulated financial marketplaces across multiple asset classes and geographies. Our MIAX Exchange marketplaces are enabled by our in-house built, proprietary technology. We believe the speed and performance of our proprietary technology coupled with our fully integrated, award-winning customer service, sets us apart from our competitors.

Our MIAX Exchange trading platform was originally built to meet the high-performance quoting demands of the U.S. options trading industry. We are regarded as a market leader relative to many of our peers with respect to our technology, based on feedback from our customers. We differentiate our trading platform with our throughput, latency, reliability and wire-order determinism.

We maintain a broad portfolio of U.S. exchange and clearing licenses, in both securities and futures. We operate markets across a diverse number of asset classes including options and cash equities as well as futures and options on futures. Our markets currently include: options on our exchanges regulated by the Securities and Exchange Commission (the “SEC”) through MIAX Options®, MIAX Pearl®, MIAX Emerald®, and MIAX Sapphire™; U.S. equities through MIAX Pearl Equities — also regulated by the SEC; U.S. futures and options on futures through MIAX Futures Exchange, LLC (“MIAX Futures”, formerly the Minneapolis Grain Exchange, LLC (“MGEX”)), which is regulated by the Commodity Futures Trading Commission (the “CFTC”); and international listings through The Bermuda Stock Exchange (“BSX”), which is regulated by the Bermuda Monetary Authority (the “BMA”), and The International Stock Exchange Group Limited (“TISEG”), which via its subsidiary, The International Stock Exchange Authority Limited (“TISEA”), is regulated by the Guernsey Financial Services Commission (“GFSC”). We also own Dorman Trading, LLC (“Dorman Trading”), a full-service Futures Commission Merchant (“FCM”) registered with the CFTC and the National Futures Association (“NFA”) and LedgerX LLC d/b/a MIAX Derivatives Exchange (“MIAXdx”), which is regulated by the CFTC, where we have the ability to list for trading fully collateralized U.S. futures and options on futures.

We entered into a master index services license agreement in July 2024 (the “Bloomberg License Agreement”) with Bloomberg Index Services Limited (“Bloomberg”) to develop a suite of proprietary products, including index futures, options on futures, and cash index options, based on Bloomberg’s portfolio of indexes as agreed to by the parties from time to time (the “Bloomberg Products”). Pursuant to a service schedule product license entered into in July 2024 (the “Service Schedule”) under the the Bloomberg License Agreement, we have a ten year exclusive license to list futures, options on futures, and cash-settled index options on (i) the Bloomberg US Large Cap Price Return Index (the “B500 Index”) and (ii) the Bloomberg US Large Cap Volatility Index (the “B500 Volatility Index”). We have the right to list these proprietary products on any of our affiliated U.S. exchanges in North and South America. The ten-year term under the Service Schedule does not expire until the tenth anniversary of the date the first product is listed. The Service Schedule also provides for automatic three-year renewal terms, provided certain minimum revenue thresholds are met.

The first Bloomberg Products we plan to exclusively list are futures and cash-settled index options on the B500 Index. We expect to launch futures on the B500 Index late in the fourth quarter of 2025 or early in the first quarter of 2026 on MIAX Futures, cash-settled index options on the B500 Index in the first half of 2026 on MIAX Options, and options on futures on the B500 Index on MIAX Futures targeted for the second half of 2026, subject to certain regulatory filings. We plan to have the Bloomberg Products cleared at The Options Clearing Corporation (“OCC”), also subject to certain regulatory filings. See “Business — Our Planned Proprietary Products.”

We currently list Hard Red Spring Wheat futures and options on futures contracts on MIAX Futures. We offer clearing services for U.S. futures and options on futures through the MIAX Futures derivatives clearing organization (“MIAX Futures Clearing”) and for futures and options on futures through the MIAXdx derivatives clearing organization (“MIAXdx Clearing”). In addition to the Bloomberg Products, we are developing other new products for our markets and plan to expand our suite of proprietary and other products on MIAX Futures and MIAXdx, and may enter into additional clearing as a service agreements with other futures markets. New MIAX Futures products will be traded on our own MIAX Futures Onyx trading system (“MIAX Futures Onyx”), which we launched on June 29, 2025.

Since launching our first options exchange in 2012, MIAX has grown to be the 14th largest global derivatives exchange operator as of June 30, 2025, as measured by the total number of futures and options contracts traded on exchanges as reported by the Futures Industry Association (the “FIA”). In 2024, trading in multi-listed U.S. options on our MIAX Exchanges totaled 1.69 billion contracts, a 6.5% increase from the 2023 total and a 30.1% increase from the 2022 total. Total volume of futures and options on futures on the MIAX Futures exchange reached 3.2 million contracts in 2024, an increase of 10.2% from the 2023 total and a 3.2% decrease from the 2022 total. For the six months ended June 30, 2025, trading in multi-listed U.S. options on our exchanges totaled 1.1 billion contracts, a 30.5% increase from the same period in 2024. Total volume of futures and options on futures on the MIAX Futures exchange was 2.2 million contracts for the six months ended June 30, 2025, an increase of 36.6% from the same period in 2024.

MIAX has a strong track record of organic growth. By increasing scale and launching new marketplaces, we have been able to substantially grow our transaction volume. Our average daily volume in U.S. options on the MIAX Exchanges increased from 1.0 million contracts in 2015 to 6.7 million contracts in 2024, a compound annual growth rate of 23.5%. Our average daily volume in U.S. options on the MIAX Exchanges in 2024 was 6.7 million contracts, as compared to 6.3 million contracts in 2023 and 5.2 million contracts in 2022. For the six months ended June 30, 2025, our average daily volume in U.S. options on the MIAX Exchanges was 8.7 million contracts, as compared to 6.5 million contracts in the same period in 2024.
