Miami International Holdings, Inc.: what insiders have been doing

Purchases and sales both appear in the filings: 3 purchases (1 insider, €621k) and 49 sales (10 insiders, €48.7M). The amount is not disclosed for 1 filing. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Among those who bought: 1 senior executive. Gallagher Thomas P. filed the largest sale, €5.3M, on 20 August 2026, which represents 0.17% of the company's market value.
With 157 filings in twelve months, the company is more active than the median of 22 filings across the 5,458 companies we follow on the same exchange. The full history, which starts in 2025, counts 15 purchases against 49 sales. For the fiscal year to 31 December 2025, the annual 10-K puts revenue at 1.36 bn USD and net income at -70.0 m USD.
The last purchase on record was published on 6 March 2026, which is 226 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. Section 16 rules allow two business days to file each Form 4. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification.
In the same market, recent insider purchases at GameStop Corp. and Heico Corp also feature in our signals. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
