Ok, so the report is on the person (CEO in this case). Only directors and certain executive levels are required to report.
Table I shows ‘non-derivative securities’ (regular stock). The CEO holds in their own name 3 million+ shares. No transaction was reported for those, but they have to be listed.
The CEO’s spouse aquired 2000 shares at a cost of $1.425 each. After this transaction, they had 2000 shares total (column 5).
They then sold those shares for $40 each. After, they weren’t holding any stock, so column 5 shows 0.
The CEO financially benefits from this, so the transactions are listed on their form, as (I) for indirect. If the spouse also had a position within Unity which required reporting this would be listed on their own SEC form as well.
