Insights

Director received equity awards with immediate vesting and a staged vesting schedule for the remainder.

The filing documents a 9,167-unit RSU grant to director Leonardo Riera with 7,206 units vesting immediately and converting to Class A Common Stock on 08/01/2025. Immediate vesting increases the director's direct shareholdings by 7,206 shares as reported in Table I.

The remaining RSUs follow a clear quarterly vesting schedule of 490 RSUs on each of 10/01/2025, 01/01/2026, 04/01/2026, and 07/01/2026, which creates future, time‑based dilution only if shares are issued upon vesting. The form is an amended filing, signed on 10/02/2025, and shows all transactions reported at a $0 per‑share conversion price.
