With the headline numbers on the table, the next step is to set these results against the main narratives around Miami International Holdings to see which stories fit the current margin profile and which start to look out of date.

Net Income Swings Back To US$170.2 Million

• Net income excluding extra items moved from a loss of US$102.1 million in Q3 2025 to a profit of US$170.2 million in Q1 2026, with the latest trailing 12 month net income sitting at US$121.6 million on US$1.4b of revenue.
• What stands out for a bullish angle is that trailing earnings grew 42% over the past year while net margin sits at 8.6%. However, the trailing period also includes a one off loss of US$67.7 million, so anyone leaning bullish has to separate the underlying profit trend from that single hit.

P/E Of 38.8x Sits Between Peers And Industry

• MIAX trades on a trailing P/E of 38.8x, compared with a peer average of 10x and a wider US Capital Markets industry average of 42.8x. The stock is therefore priced above its closer peer group but below the broader industry.
• Bears often point to valuation first, and here they have some backing because the 38.8x multiple is materially higher than the 10x peer average. The same data also shows earnings growth of 42% and a net margin of 8.6%, which gives bullish investors concrete profitability figures to set against that richer peer comparison.

Revenue Steady While Trailing Margins Improve

• Quarterly revenue has hovered in a tight band, from US$327.1 million in Q1 2025 to US$369.7 million in Q1 2026, while trailing net profit margin is 8.6% compared with 7.2% a year earlier on US$1.4b of revenue.
• What challenges a more bearish stance is that, despite forecasts indicating revenue could decline by 24.4% per year over the next three years, the reported trailing period still shows higher earnings and a stronger margin. Anyone taking a cautious line therefore needs to weigh those projected revenue pressures against the currently reported profitability profile.
