"MIH produced strong results in the third quarter while also executing on a successful initial public offering, driven by our team's focus on providing customers with best-in-class technology, reliability and risk protections across our markets," said Thomas P. Gallagher, Chairman and Chief Executive Officer of MIH. "Elevated volatility supported record volumes, contributing to strong performance in our options business. Notably, we achieved record average daily volume of 9.6 million contracts across our options exchanges for the third quarter, increasing 56% over the same period in the prior year." "Looking ahead, we remain committed to leveraging our ongoing investments in technology, relationships and industry expertise as we seek to further expand market share in our options business and grow our equities, futures, and international segments. With a strong foundation to build on, we are well-positioned to execute on our growth strategy and create long-term shareholder value." Third Quarter 2025 Highlights All figures are compared to the third quarter of 2024 unless otherwise stated. • Net revenue, defined as revenues less cost of revenues, grew 57% to $109.5 million, compared to $69.6 million in the prior-year period primarily driven by strong options business performance, including increased industry volumes and the launch of the MIAX Sapphire® electronic options exchange in August 2024. • Total operating expenses were $109.8 million, compared to $70.7 million in the prior-year period primarily due to initial public offering (IPO) related expenses and planned increases in headcount to support our growth initiatives. • Operating loss of $0.3 million, compared to an operating loss of $1.2 million in the prior-year period. • GAAP net loss of $102.1 million, compared to GAAP net loss of $3.2 million in the prior-year period primarily due to one-time loss on extinguishment of debt and IPO-related expenses. • Adjusted earnings increased nearly five times to $39.9 million, compared to adjusted earnings of $8.3 million in the prior-year period. • Adjusted EBITDA more than doubled to $48.0 million, compared to $18.7 million in the prior-year period driven primarily by strong growth in net revenues. • Adjusted EBITDA margin expanded to 44% from 27% in the prior-year period. Business Updates • Launched the MIAX Sapphire options trading floor in Miami in September 2025. • MIAX® options exchanges reached a market share record of 17.2% in the third quarter of 2025.

Summary of Selected Unaudited Condensed Consolidated Financial Results ($000, except per share amounts and percentages) Consolidated Third Quarter Results 3Q25 September 30, 2025 3Q24 September 30, 2024 Change Total revenues less cost of revenues $109,483 $69,558 57% Operating loss $(305) $(1,159) NA Net loss attributable to MIH stockholders $(102,080) $(3,204) NA Diluted EPS $(1.46) $(0.05) NA Adjusted earnings\* $39,947 $8,273 383% Adjusted diluted EPS\* $0.42 $0.11 282% EBITDA $(93,941) $5,768 NA Adjusted EBITDA\* $48,019 $18,690 157% Adjusted EBITDA margin %\* 44% 27% 63% \* Reconciliation of non-GAAP results is included in the tables below. See "Non-GAAP Financial Information" below. Segment Results ($000) Total Revenues Less Cost of Revenues (Net Revenue) by Business Segment 3Q25 September 30, 2025 3Q24 September 30, 2024 Change Options $94,499 $60,925 55% Equities 4,352 2,234 95% Futures 4,786 5,288 (9)% International 5,533 806 586% Corporate/Other 313 305 3% Total $109,483 $69,558 57% Options • Net revenue grew 55% to $94.5 million, compared to $60.9 million in the prior-year period. The growth was primarily driven by higher net transaction fees that benefitted from increased industry volume, higher market share, and higher revenue per contract (RPC). Higher non-transaction fees were primarily driven by the launch of the MIAX Sapphire electronic options exchange in August 2024 which also contributed to increased revenues. • Operating income increased 56% to $51.4 million, compared to $32.9 million in the prior-year period. The growth was primarily due to higher net revenues, partially offset by higher expenses driven by share- based compensation costs. • Adjusted EBITDA grew 70% to $69.1 million, compared to $40.7 million in the prior-year period. 2

![](miax3q25earningsrelease003.jpg)

Equities • Net revenue nearly doubled to $4.4 million, compared to $2.2 million in the prior-year period. The increase was primarily due to higher net transaction fees from improved but still negative pricing as liquidity payments exceeded transaction revenues. • Operating loss of $4.9 million, compared to an operating loss of $5.0 million in the prior-year period. • Adjusted EBITDA of $(0.9) million, compared to $(2.5) million in the prior-year period. Futures • Net revenue was $4.8 million, compared to $5.3 million in the prior-year period. The decrease was due to participant migrations to the MIAX Futures Onyx trading platform and lower commodity market volatility, partially offset by the elimination of expenses related to CME Globex. • Operating loss was $18.5 million, compared to an operating loss of $12.8 million in the prior-year period. The change was primarily due to lower revenue and higher operating expenses driven by share-based compensation costs. • Adjusted EBITDA of $(9.6) million, compared to $(8.0) million in the prior-year period. International • Net revenue was $5.5 million, compared to $0.8 million in the prior-year period. The increase was primarily due to the acquisition of The International Stock Exchange Group Limited (TISE) in June 2025. • Operating income was $0.8 million, compared to an operating loss of $2.6 million in the prior-year period. The change was primarily due to the impact of the TISE acquisition. • Adjusted EBITDA of $1.7 million, compared to $(1.7) million in the prior-year period. Capital and Liquidity • On August 13, 2025, MIH raised $396.8 million in gross proceeds from its IPO of 17,250,000 shares of common stock, including the full exercise of the underwriters' option to purchase additional shares. • On August 18, 2025, MIH repaid its outstanding senior secured loan agreement maturing in 2029. The amount repaid by MIH included $178.4 million of outstanding indebtedness, accrued and unpaid interest, the related premium, and fees. • As of September 30, 2025, MIH had cash and cash equivalents of $401.5 million and total debt of $6.5 million.
