Miami International (MIAX) Financials

Miami International Holdings (NYSE: MIAX) showed strong revenue growth and very solid cash generation in Q1 2026, but profitability still depends heavily on a large non-operating gain. The company continues to grow its top line, maintain a large cash balance, and produce positive operating cash flow, but the income statement also shows that core operating earnings remain modest relative to reported net income.

Quarter-over-quarter, the business improved materially from Q1 2025. Revenue rose to $369.7 million from $327.1 million, while gross profit increased to $128.6 million from $91.9 million. Operating income also improved to $46.0 million from $22.3 million, and the company swung from a net loss of $21.4 million to net income of $170.2 million. However, that sharp earnings jump was largely driven by a large “other income” line, not just by core operations.

Cash flow remains a key strength. MIAX generated $60.9 million of operating cash flow in Q1 2026, up from $11.2 million in Q1 2025. It also produced $45.6 million of investing cash flow, helped by $59.8 million tied to acquisitions, and ended the quarter with $113.1 million of net cash increase. That indicates the company is still converting its business into cash, which is important for a financial exchange operator.

The balance sheet looks healthy overall. As of March 31, 2026, MIAX held $550.8 million in cash and equivalents plus $41.2 million in restricted cash. Total assets were $1.44 billion versus total liabilities of $378.6 million, leaving shareholders’ equity of about $1.07 billion. Debt also appears manageable, with only $1.5 million of short-term debt and no meaningful long-term debt shown in the latest quarter.

• Revenue rose 13% year over year in Q1 2026, showing continued business expansion.
• Gross profit climbed to $128.6 million from $91.9 million, reflecting better absolute earnings power.
• Operating income improved to $46.0 million from $22.3 million in the prior-year quarter.
• Operating cash flow surged to $60.9 million, a strong sign of underlying liquidity generation.
• The company ended Q1 2026 with more than $550 million in cash and equivalents.
• Leverage appears low, with very limited debt on the balance sheet.
• Q1 2026 net income of $170.2 million was far above operating income, suggesting a large non-operating contribution.
• Other income was unusually high in Q1 2026 at $49.7 million, which may not be repeatable every quarter.
• Shares outstanding increased versus Q1 2025, which can dilute per-share results over time.
• Q3 2025 showed the company can still swing to a quarterly net loss when other income weakens and expenses rise.

There are some areas investors should watch closely. While operating revenue and operating income are trending in the right direction, MIAX’s earnings can be volatile because other income and expense items have a major impact on quarterly results. For example, Q3 2025 posted a net loss of $102.1 million despite $109.5 million of gross profit, mainly because of a large negative other-income result and very high interest expense. That kind of volatility means headline earnings may overstate the consistency of the underlying business.

Bottom line: MIAX looks financially solid, liquid, and growing, but investors should focus on whether the company can keep expanding core operating income without relying on large non-recurring gains. The balance sheet and cash flow are strengths, while earnings quality and quarterly volatility remain the main watch items.
