How does the CMO of Unity have $13m value of inventory whereas solely having labored there for one 12 months?

I used to be studying this text https://www.marketbeat.com/instant-alerts/nyse-u-sec-filing-2023-03-10/

And apparently she bought about $1m value of the inventory not too long ago however nonetheless has over $12m value? How?

I'm having a tough time seeing the way it provides up particularly contemplating unity share value had steady been falling, which suggests the worth on the time of buy ought to have been even increased.

Even when she is 100% compensated by way of inventory, it appears method too excessive for one 12 months except she bought like $10m value of the inventory together with her personal cash which i doubt. Can somebody assist me make sense of this?
