Insights

Equity markets analyst

Routine Rule 144 notice of insider stock sales with modest size.

The notice shows Jon Christianson planning several sales of PLMR common shares under Rule 144, using Morgan Stanley Smith Barney LLC as broker on the NASDAQ. The disclosed aggregate market values indicate individual transactions but do not, by themselves, suggest a transformational change.

The filing also details that the shares were granted as compensation (restricted and performance stock) and that Christianson sold additional shares in November and December 2025. With 26,494,524 shares outstanding, these transactions appear relatively small, so the information is useful for transparency but does not clearly alter the overall equity story.
