PRINCETON, N.J. and MIAMI, Aug. 5, 2026 /PRNewswire/ -- Miami International Holdings, Inc. (MIAX or MIH) (NYSE: MIAX), a technology-driven leader in building and operating regulated financial markets across multiple asset classes, today announced financial results for the second quarter of 2026.

MIAX achieved strong financial performance in Q2 2026 with record net revenue, adjusted EBITDA, and adjusted earnings. Total net revenue grew 35% year-over-year to $141.1 million, adjusted EBITDA increased 57% to $76.8 million, and adjusted EBITDA margin expanded by more than 700 basis points to 54%. Adjusted diluted earnings per share was $0.48. The company's options business benefited from elevated market volatility during the quarter, which led to a 25% year-over-year increase in average daily volume to 11.0 million contracts.

"We delivered another record quarter, growing net revenue 35% year-over-year and successfully navigating a shifting market backdrop, demonstrating both our ability to execute consistently as well as sustained customer demand," said Thomas P. Gallagher, Chairman and Chief Executive Officer of MIAX. "Our options business remains strong, our model's operating leverage drove record margins, and our Bloomberg^® index futures suite is now live."

Mr. Gallagher added: "We remain disciplined in how we allocate capital and execute our strategy, and continue to invest in a product pipeline that we expect will contribute meaningfully to continued, long-term growth."

Second Quarter 2026 Highlights

All figures are compared to the second quarter of 2025 unless otherwise stated.

Net revenue, defined as revenues less cost of revenues, grew 35%, or $36.5 million, to a record $141.1 million, compared to $104.7 million in the prior-year period. The increase was primarily driven by strong options business performance, including increased industry volumes and higher non-transaction revenue.
Total operating expenses were $113.3 million, compared to $77.4 million in the prior-year period. The increase was primarily due to a litigation settlement charge as well as planned investments in headcount and technology to support growth initiatives, and increased marketing spend. These were partially offset by lower regulatory costs, lower share-based compensation, and 2025 acquisition-related costs.
Operating income was $27.8 million, compared to $27.3 million in the prior-year period.
Realized an income tax benefit of $15.4 million, primarily driven by a discrete tax benefit of $22.4 million related to share-based compensation.
GAAP net income was $44.2 million, compared to $23.5 million in the prior-year period.
Adjusted earnings increased 41% to $53.3 million, compared to $37.8 million in the prior-year period.
Adjusted EBITDA increased 57% to $76.8 million, compared to $49.1 million in the prior-year period, driven primarily by strong growth in net revenues.
Adjusted EBITDA margin expanded to 54% from 47% in the prior-year period.

Second Quarter 2026 Business Updates

MIAX options exchanges reached average daily volume of 11.0 million contracts in the second quarter of 2026, a 25.3% year-over-year (YoY) increase.
MIAX options exchanges achieved market share of 16.5% in the second quarter of 2026, compared to 16.7% in the prior year period.

Options

Net revenue grew 34% to $124.4 million, compared to $92.8 million in the prior-year period. Growth was primarily driven by higher net transaction fees tied to increased industry volume, and higher revenue per contract (RPC). Higher non-transaction fees were primarily driven by increased member connections, 2026 fee increases, the expiration of certain MIAX Sapphire related fee waivers, and new market data products.
Operating income increased 10% to $64.9 million, compared to $59.2 million in the prior-year period. Growth was primarily due to higher net revenues, partially offset by a $22.5 million litigation settlement charge.
Adjusted EBITDA grew 44% to $96.7 million, compared to $67.0 million in the prior-year period.

Equities

Net revenue grew 27% to $5.5 million, compared to $4.4 million in the prior-year period. The increase was primarily due to higher net transaction fees from improved pricing.
Operating loss of $2.3 million in the second quarter, compared to an operating loss of $3.1 million in the prior-year period. Growth was primarily due to higher net revenues.
Adjusted EBITDA of ($0.5) million, compared to ($0.9) million in the prior-year period.

Futures

Net revenue was $5.1 million, compared to $5.0 million in the prior-year period. Net transaction fees were flat as increases in agricultural future revenues were offset by inverted financial futures revenue.
Operating loss was $12.7 million, compared to an operating loss of $12.8 million in the prior-year period.
Adjusted EBITDA of ($9.5) million, compared to ($9.0) million in the prior-year period.

International

Net revenue was $5.7 million, compared to $2.3 million in the prior-year period. The increase was primarily due to revenue generated by The International Stock Exchange Group Limited (TISE), which the company acquired in June 2025.
Operating income was $1.1 million, compared to an operating loss of $1.2 million in the prior-year period. The increase was primarily due to the impact of the TISE acquisition.
Adjusted EBITDA of $2.0 million, compared to ($0.6) million in the prior-year period.
