Korro Bio, Inc. (NASDAQ: KRRO) disclosed that director Jean Francois Formela sold approximately $2.46 million worth of company shares, according to a Form 4 filing with the U.S. Securities and Exchange Commission (SEC).
The reported sales occurred across three trading days. Formela sold 3,962 shares on June 22 at an average price of $13.95, 119,005 shares on June 23 at an average price of $14.25, and 48,438 shares on June 24 at an average price of $14.61.
In total, the filing showed 171,405 shares sold.
Korro Bio is a biotechnology company focused on developing genetic medicines, including RNA editing therapies designed to treat serious diseases.
The sale is notable because it crossed the $1 million threshold often used to flag meaningful insider selling.
Single insider sales above $1 million are generally worth reviewing, while sales above $5 million tend to draw greater investor attention.
In this case, Formela’s reported sales totaled approximately $2.46 million, making the filing relevant but below the highest-signal insider-selling range.
The largest reported sale occurred on June 23.
Formela sold 119,005 shares at an average price of $14.25 per share, valued at approximately $1.7 million.
That one transaction date accounted for most of the total reported sale value.
The dashboard showed 169,556 shares owned indirectly after the latest reported sale.
The detailed Form 4 also listed another indirect ownership line with 793,328 shares after related June 24 transactions.
That means the 169,556-share figure should be read as tied to a specific indirect ownership line, not necessarily the reporting person’s entire economic exposure across all affiliated holdings.
The sales were reported across June 22, June 23, and June 24, with average sale prices ranging from $13.95 to $14.61.
Repeated selling over several trading days can become more relevant when it continues across additional filings or rises above larger dollar thresholds.
For now, the cleaner takeaway is that a director reported nearly $2.5 million in stock sales while still showing indirect ownership after the transactions.
Insider sales become more meaningful when they exceed common dollar thresholds, occur repeatedly, or reduce reported ownership positions sharply.
