Eckert Kurt M. 4

What Happened

• Kurt M. Eckert, a director of Miami International Holdings, Inc. (MIAX), received awards totaling 14,950 shares reported as grants/awards (transaction code A). The filings show: 2,267 RSUs on 2026-06-15 (vested on grant), 4,970 RSUs on 2026-06-16 (scheduled to vest before the 2027 annual meeting), and 7,713 derivative awards on 2026-06-16 with a time-based vesting schedule. All awards are reported at $0.00 purchase price because these are compensation awards (RSUs/options), not open-market purchases.

Context

• These were compensation awards (RSUs/derivative awards) rather than open-market buys or sales, so no cash outlay or proceeds occurred at grant. Vesting is contingent on continued service for most of the grants; vested RSUs typically convert to shares and may be subject to withholding or sale for taxes per company practice (not detailed here). Such awards are common executive/director compensation and are informational rather than a direct market signal of buying/selling intent.
