Business Overview: MIH operates regulated financial marketplaces across options, futures, and cash equities through its MIAX Exchanges, MIAX Futures, and international listings (BSX, TISE).

Key Financial Metrics (Nine Months Ended Sept 30, 2025)

|---|---|
| Total Revenues | $994,639 |
| Net Income (Loss) | $(99,973) |
| Operating Income | $49,279 |

| Cash and Cash Equivalents | $401,482 |
| Total Debt (Carrying Value) | $6,463 |

Note: Net loss is significantly impacted by non-operating items, specifically a $107.7 million loss on debt extinguishment and a $39.0 million unrealized loss on derivative assets (Pyth tokens).
Material Changes vs. Prior Period
- Revenue Growth: Total revenues increased 21.9% to $994.6 million (from $816.2 million in 2024), driven by a 34.6% increase in Options transaction fees and the acquisition of TISE.
- Profitability Shift: The company reported a net loss of $100.0 million for the nine months ended Sept 30, 2025, compared to net income of $99.2 million in the prior year. This reversal is primarily due to the $107.7 million loss on debt extinguishment and $39.0 million unrealized loss on Pyth tokens, which offset strong operating performance.
- Debt Reduction: Following an August 2025 IPO, the company repaid its entire $140.0 million 2029 Senior Secured Term Loan. Total debt outstanding dropped from $106.5 million (Dec 31, 2024) to $6.5 million (Sept 30, 2025).
- Segment Performance: The Options segment generated $161.1 million in operating income, while the Futures segment reported an operating loss of $42.6 million, largely due to platform migration costs and liquidity incentives.
Guidance, Outlook, and Risks
- Capital Resources: The company raised approximately $369.0 million in net proceeds from its August 2025 IPO. Management believes available cash and operating cash flows are adequate for the next 12 months.
- Strategic Initiatives: MIH plans to launch financial futures on the MIAX Futures Onyx platform in early 2026, including products based on Bloomberg indexes (B500, B100Q).
- Key Risks:
- Regulatory: Ongoing CFTC inquiries regarding MIAXdx (related to prior FTX ownership) and potential changes to CAT funding models which could impact fee recovery.
- Market Volatility: Significant exposure to Pyth token valuation, which resulted in a $39.0 million unrealized loss in the period.
- Competition: Intense price competition in transaction fees and the need to maintain order flow from Equity Rights Program (ERP) participants post-IPO.
Investor Verification Checklist
- Debt Extinguishment Impact: Verify the sustainability of earnings excluding the one-time $107.7 million debt extinguishment loss and $39.0 million Pyth token unrealized loss.
- Pyth Token Exposure: Assess the remaining exposure to 250 million locked Pyth tokens (valued at $27.0 million) and the volatility risk associated with their future unlocking and sale.
- Options Segment Dominance: Confirm the continued growth trajectory of the Options segment, which contributed the majority of operating income ($161.1 million YTD).
- Regulatory Status: Monitor the outcome of CFTC inquiries into MIAXdx and the SEC's decision on the CAT funding model by the November 29, 2025 deadline.
- Liquidity Payments: Review the ratio of liquidity payments to transaction fees, particularly in the Equities segment where "inverted pricing" (payments exceeding fees) remains a factor.
