The cluster is too small to be a material signal. Monitor for any upcoming 8-K or press release that might explain the shared sale date (e.g., blackout window opening, 10b5-1 plan adoption, or a routine quarterly vesting event). Without a catalyst, this filing is neutral.
Price Chart
Executive Summary
Four senior insiders at Korro Bio (COO, CSO, SVP Finance, General Counsel) sold a total of $180K in open-market sales on June 16, 2026, all at $10.83 per share. The cluster is small relative to the $154M market cap (0.12%), and the sales are concentrated on a single day, consistent with a shared blackout-window or vesting-driven event rather than an informational signal.
Key Financial Metrics
Key Facts
- Four insiders sold a total of 16,578 shares at $10.83 on June 16, 2026, for $180K.
- Total sales represent 0.12% of KRRO's $154M market cap — well below the 0.5% materiality threshold.
- All sales were open-market (S code) and occurred on the same day, suggesting a shared liquidity event (blackout window, 10b5-1 plan, or vesting).
- No insider purchases were reported in the cluster; the net direction is entirely selling.
- The company's analyst consensus is 81% bullish (4 Strong Buy, 9 Buy), but the stock has a $154M market cap in the pharmaceutical preparations sector.
Financial Impact
$180K total sales, 0.12% of market cap — trivial
Risk Factors
- No insider purchases to offset the selling — all sales are one-directional, but the dollar amount is trivial.
- The stock has a small market cap ($154M) and low liquidity, so even small sales could be amplified in percentage terms, but the absolute value is routine.
