Industry Context

The company's strong options business performance, including record average daily volume and market share, was supported by elevated market volatility, which is a broader industry trend benefiting exchange operators. The expansion into new futures products with Bloomberg indices and the acquisition of TISE reflect a strategy to diversify across asset classes and geographies, aligning with trends of global financial market integration and product innovation.

Comparison to Industry Standards

• Achieved record average daily volume of 9.6 million contracts across options exchanges for Q3 2025, representing a 56% increase over the prior year, outperforming the overall market's 25.6% increase in equity and ETF market contracts.
• MIAX options exchanges reached a market share record of 17.2% in Q3 2025, a 3.3 percentage point increase from 13.9% in Q3 2024, indicating significant market share gains against competitors.
• The 57% net revenue growth significantly outpaces typical growth rates for established exchange operators, suggesting strong competitive positioning and successful strategic initiatives.

Legal Proceedings

• Ongoing litigation related to the Nasdaq matter.

Stakeholder Impact

• Shareholders: The IPO provided liquidity and capital, while the debt repayment strengthens the balance sheet. Strong adjusted earnings and growth prospects could lead to increased shareholder value, despite the temporary GAAP loss.
• Employees: Increased headcount to support growth initiatives and one-time IPO bonuses were paid to certain employees, indicating positive impact.
• Customers: Continued focus on best-in-class technology, reliability, and risk protections across markets, along with new product launches (MIAX Sapphire, Bloomberg Index futures), aims to enhance customer offerings.
• Creditors: Repayment of the senior secured loan significantly reduces the company's debt burden and improves its credit profile.

Next Steps

• MIAX will host a webcast and conference call on November 5, 2025, at 5:00 p.m. ET to review third-quarter financial results.
• MIAX Futures will announce support for the trading of financial futures on the MIAX Futures Onyx trading platform in the first quarter of 2026.
• MIAX Futures will list futures on the Bloomberg 500 Index in collaboration with Bloomberg during the first quarter of 2026.

Recommendation

The filing reveals a company with exceptional underlying operational momentum, evidenced by a 57% increase in net revenue, a doubling of Adjusted EBITDA, and a nearly five-fold increase in Adjusted Earnings. The significant GAAP net loss is primarily attributable to one-time, non-recurring expenses associated with a successful IPO and the strategic extinguishment of substantial debt, both of which are long-term positives for the company's financial health and capital structure. The record options market share and expansion into new product offerings (Bloomberg Index futures) demonstrate strong competitive positioning and a clear growth strategy. With a significantly de-leveraged balance sheet and robust cash position post-IPO, Miami International Holdings is well-positioned for sustained growth and market leadership. The one-time charges obscure a fundamentally strong performance, making this an attractive entry point for long-term investors.
