The insider's one prior sale at NP on 2025-10-01 was followed by a 90-day return of +59.2%, and the cross-ticker well-timed rate stands at 0.00%, reflecting that prior sells have not preceded stock declines.

BSIV Hold 101, LP (10% Owner) sold 820,123 shares of NP at $18.75 on 2025-10-01, reducing stake by 4.0% to 19,530,472 shares.

A significant 10% shareholder of Neptune Insurance Holdings disposed of 820,123 shares for $15,377,306.25 just three trading days after the company's IPO listing, executing the sale at $18.75—well below the current market price of $30.40. This material stake reduction by a major owner early in the company's public market history represents a substantial capital event. The timing immediately post-listing, combined with the substantial gap between the execution price and current price, suggests the shareholder's transaction occurred amid the initial public market volatility phase. The 4.0% reduction in holdings signals a meaningful but not complete exit by the 10% owner.
