Miami International Holdings Reports 22.8% Revenue Growth but $102.1 Million Net Loss in Q3 2025

Miami International Holdings, Inc. (MIH) reported significant financial developments in its latest 10-Q filing for the quarter ending September 30, 2025. The company achieved total revenues of $339.8 million for the third quarter, marking a 22.8% increase from $276.7 million in the same period last year. For the nine months ended September 30, 2025, revenues reached $994.6 million, up 21.9% from $816.2 million in the prior year. The increase in revenue was primarily driven by a substantial rise in transaction and clearing fees, which totaled $292.8 million for the quarter, a 21.7% increase year-over-year, and $868.3 million for the nine-month period, reflecting a 21.9% increase.

Despite the revenue growth, MIH reported a net loss of $102.1 million for the third quarter, compared to a loss of $3.2 million in the same quarter of 2024. The nine-month net loss was $100.0 million, a stark contrast to a net income of $99.1 million for the same period last year. The losses were attributed to a $107.7 million loss on debt extinguishment related to the repayment of the 2029 Senior Secured Term Loan, as well as unrealized losses on derivative assets. The company also experienced increased operating expenses, which rose 55.2% to $109.8 million for the quarter, driven by higher compensation and benefits costs, including share-based compensation linked to the company's recent IPO.

Strategically, MIH completed its initial public offering (IPO) on August 15, 2025, raising approximately $396.8 million in gross proceeds. This capital was utilized to repay outstanding debt, including the full balance of the 2029 Senior Secured Term Loan. Additionally, MIH expanded its market presence through the acquisition of the International Stock Exchange Group Limited (TISEG) in June 2025, which is expected to enhance its international operations and revenue streams. The acquisition contributed $4.7 million to revenues in the third quarter.

Operationally, MIH reported a 25.6% increase in options market contracts and a 56.1% increase in MIH options contracts for the third quarter, indicating strong engagement in its options trading segment. The company also launched MIAX Sapphire, its fourth electronic U.S. equity options exchange, in August 2024, which has contributed to increased access fees and market data revenues. However, the equities segment saw a decline in transaction and clearing fees, attributed to a decrease in market share and pricing pressures.

Looking ahead, MIH anticipates that its cash from operations, combined with available cash and borrowings, will be sufficient to meet its liquidity needs for the next 12 months. The company remains focused on expanding its market share and product offerings while navigating the competitive landscape of financial marketplaces.
