Key Terms

adjusted ebitda, adjusted earnings, adjusted eps, non-gaap financial measure, +4 more

8 terms

adjusted ebitda financial

"Q4 Adjusted EBITDA of $62.2 million (+112% YoY), Adjusted diluted EPS of $0.52"

Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.

adjusted earnings financial

"Adjusted earnings increased nearly three times to $57.1 million, compared to $19.6 million"

Adjusted earnings are a company’s profit figure that has been altered to remove one-time, unusual or non-operational items so it better reflects the business’s regular performance. Think of it like looking at a household budget but ignoring a big, unusual expense or windfall to see what normal monthly cash flow looks like; investors use adjusted earnings to compare companies and trends, but should watch what is excluded because choices can change the picture.

adjusted eps financial

"Adjusted diluted EPS of $0.52"

Adjusted earnings per share (adjusted eps) is a measure of a company's profit per share that has been modified to exclude certain one-time or unusual items, such as costs from restructuring or asset sales. It provides a clearer picture of the company’s core performance by removing events that may distort the usual earnings. Investors use adjusted eps to better understand a company's ongoing profitability and compare it more accurately over time.

non-gaap financial measure financial

"Adjusted earnings, a non-GAAP financial measure, is defined as net income (loss)"

A non-GAAP financial measure is a way companies present their financial results that excludes certain expenses or income to show how they believe their core business is performing. It matters because it can give a clearer picture of how the company is really doing, but it can also be used to make results look better than they actually are.

ebitda financial

"EBITDA | $ 35,041 | $ 12,623 | 178 %"

EBITDA stands for earnings before interest, taxes, depreciation, and amortization. It measures a company's profitability by focusing on the money it makes from its core operations, ignoring expenses like taxes and accounting adjustments. Investors use EBITDA to compare how well different companies are performing financially, as it provides a clearer picture of operational success without the influence of financial structure or accounting choices.

View in glossary

diluted eps financial

"GAAP diluted EPS of $0.27"

Diluted earnings per share (EPS) shows how much profit a company makes for each share of stock, assuming all possible shares from stock options or convertible securities are used. It provides a more conservative estimate than basic EPS, accounting for potential share increases that could dilute ownership. Investors use diluted EPS to get a clearer picture of a company's true profitability on a per-share basis.

capital expenditures financial

"Capital expenditures, including capitalization of internally developed software, in a range between $40 million and $45 million"

Capital expenditures are the money a company spends to buy or improve big assets like buildings, equipment, or machines that will last a long time. These investments matter because they help the company grow and operate more efficiently, similar to how upgrading a home’s appliances or adding a new room can make it better and more valuable.

View in glossary

effective tax rate financial

"Adjusted effective tax rate post valuation allowance release in a range between 27% and 29%"

The effective tax rate is the percentage of a company's profits that it pays in taxes. It shows how much of its earnings go to taxes after all deductions and credits are considered. For investors, it indicates how much of the company's income is taken by taxes, impacting overall profitability and financial health.

PRINCETON, N.J. and MIAMI, Feb. 25, 2026 /PRNewswire/ -- Miami International Holdings, Inc. (MIAX) (NYSE: MIAX), a technology-driven leader in building and operating regulated financial markets across multiple asset classes, today announced results for the fourth quarter and full year 2025.

"We ended a milestone year with another exceptional quarter of progress," said Thomas P. Gallagher, Chairman and Chief Executive Officer of MIAX. "Beyond our strong financial results and record volumes, 2025 was marked by a number of transformative strategic achievements including our successful IPO and secondary offering, the announcement of our strategic sale of 90% of MIAXdx, the launch of the MIAX Sapphire options trading floor in Miami, the launch of the MIAX Futures Onyx trading platform, and the completion of our acquisition of TISE."

"We have built a strong foundation for capturing emerging secular growth opportunities. Looking ahead, we'll leverage our technology advantage, broad range of regulatory licenses across multiple jurisdictions, diverse and expanding product range, and most importantly, our deep relationships with our customers to drive continued growth."

• Total operating expenses were $81.8 million, compared to $74.5 million in the prior-year period. The increase was primarily due to planned investments in headcount and technology to support our growth initiatives; increased depreciation and amortization expenses related to the launch of the MIAX Sapphire electronic and floor exchange; and the launch of the MIAX Futures Onyx trading platform.
• Operating income of $42.7 million, compared to $7.2 million in the prior-year period.
• GAAP net income of $29.9 million, compared to $2.9 million in the prior-year period.
• Adjusted earnings increased nearly three times to $57.1 million, compared to $19.6 million in the prior-year period.

Options

• Net revenue grew 46% to $106.9 million, compared to $73.1 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 full-year impact of the launch of the MIAX Sapphire electronic options exchange.
• Operating income increased 80% to $73.0 million, compared to $40.6 million in the prior-year period. The growth was primarily due to higher net revenues.
• Adjusted EBITDA grew 66% to $82.5 million, compared to $49.7 million in the prior-year period.

Equities

• Net revenue grew 245% to $6.4 million, compared to $1.8 million in the prior-year period. The increase was primarily due to higher net transaction fees from improved pricing. Equities capture was net neutral for the quarter as compared to historically inverted.
• Approached operating breakeven in the fourth quarter, compared to an operating loss of $6.3 million in the prior-year period.
• Adjusted EBITDA of $1.6 million, compared to ($3.8) million in the prior-year period.

Futures

• Net revenue was $4.8 million, compared to $5.6 million in the prior-year period. The decline was primarily due to lower listings fees, and decreased transaction fees due to lower volumes caused by timing of participant migrations to MIAX Futures Onyx and lower commodity market volatility, partially offset by the elimination of expenses related to CME Globex.
• Operating loss was $14.2 million, compared to an operating loss of $11.0 million in the prior-year period. The change was primarily due to lower revenue and higher operating expenses driven by increased compensation costs.
• Adjusted EBITDA of ($10.0) million, compared to ($6.9) million in the prior-year period.

International 

• Net revenue was $6.0 million, compared to $0.9 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 $0.9 million, compared to an operating loss of $2.8 million in the prior-year period. The change was primarily due to the impact of the TISE acquisition.
• Adjusted EBITDA of $1.8 million, compared to ($2.0) million in the prior-year period.

Capital and Liquidity

• As of December 31, 2025, MIAX had cash and cash equivalents of $433.6 million and total debt of $1.5 million.

FY 2026 Guidance

For full year 2026, we expect:

• Adjusted operating expenses, which exclude share based compensation, depreciation and amortization, and litigation expenses, in a range between $265 million and $275 million;
• Share based compensation expense in a range between $27 million and $30 million;
• Capital expenditures, including capitalization of internally developed software, in a range between $40 million and $45 million;
• Depreciation and amortization expense in a range between $33 million and $38 million;
• Adjusted effective tax rate post valuation allowance release in a range between 27% and 29%. Subject to continued improvements in U.S. operating results, the Company anticipates that within the next 12 months, sufficient positive evidence should become available to reach a conclusion that a significant portion of the deferred tax valuation allowance (VA) would no longer be required. The Adjusted ETR is based on non-GAAP adjusted earnings and excludes the discrete tax benefit of the anticipated VA release.
