Context

• The disposal was for tax withholding tied to the RSU grant — a routine administrative transaction common when equity awards vest or are granted. It should not be interpreted as a discretionary sale signaling a change in insider sentiment.
• For retail investors, the notable item is the RSU grant (18,354 units) which represents future potential equity if and when the units vest on 2028-12-31.
