Context

• These entries are RSU vesting/conversion and a new RSU grant — not open‑market purchases or sales. The “disposed” derivative entry reflects conversion of the RSU instrument into shares, not a market sale for cash.
• RSU grants and vesting are common director compensation; new grants indicate future compensation tied to continued service and/or performance, while vested RSUs convert to ordinary shares available to the insider.
