The sale is small and routine — not likely to move the stock. However, Kampani sold 52,472 shares in early March (about $3.66M) and now plans another 9,100 share sale. While this is still modest relative to his likely holdings and the float, the sequential insider selling pattern at an all-time-high-ish price level is worth monitoring. The 88% win rate on past RKLB reports suggests the stock has strong momentum, but insiders taking some chips off the table is typical at these valuations.
