Insiders at Flat Capital AB (publ)

Shares is a position we rebuilt from reported transactions — not a disclosed balance.

Reconstructed by adding up every transaction this person reported to FI since 2016. FI publishes transactions, not balances, so this is a computed figure, not a disclosed one — and it omits anything held before the register began.

Value is that share count priced at the same closing price used everywhere else on this site. A row priced from only some of a person’s securities says so — we do not quietly present a partial sum as a complete one.

Recent insider transactions

Of the 51 rows we hold, 0 are open-market purchases and 3 open-market sales (SDIS) — the only codes we count as buying or selling.

The rest — awards, shares withheld to pay tax, option exercises, gifts and so on — follow from an employment contract or a transfer arranged off-market, not from a decision to buy or sell, so counting them would turn this into a pay table.

A price of 0.00 is a real reported figure on allotments, gifts and option exercises — not a gap in our data.
