A Form 4 is filed within two business days of a company insider — an officer, a director, or a holder of more than ten percent of the stock — changing their position in the shares. All 12 filings in this group are Form 4s for Brilliant Earth Group, Inc.
The difficulty with reading these filings as a group is that a single form type covers transactions that mean entirely different things. An executive spending their own money to buy stock and an executive having shares withheld to pay tax on a vesting grant both appear as a Form 4. Every filing below is therefore tagged with the nature of the underlying transaction, taken from the transaction code reported on the form itself.
Across the 12 insider filings shown, the breakdown is 4 open-market sale, 3 compensation award, 3 open-market purchase and 2 other reported transaction. 7 of them involved a discretionary open-market trade; the rest are compensation and administrative mechanics.
