Equity Compensation Analyst

Routine increase in equity plan capacity; potential dilution depends on future grants.

The board approved expanding the 2021 equity plan by 1,971,428 shares, setting a new cap of 2,000,000 Class A ordinary shares available for awards. Equity plans are commonly adjusted to maintain capacity for employee and executive incentives.

This action does not itself issue shares; any dilution would occur as awards are granted and settle. The filing also notes incorporation by reference into existing Form F‑3 and Form S‑8, a standard procedural step.
