The company leverages disciplined underwriting and diversified distribution channels to drive profitable growth and manage risk exposure.

What this transaction means for investors
Before January closed, there was another transaction a week later, in which Armstrong acquired 22,907 shares directly through a performance stock unit (PSU) award granted three years prior. The shares were vested on Jan. 28, 2026, because Armstrong met the company’s requirements for acquiring the shares.
Out of the total number of shares vested that day, 11,484 shares were automatically sold, as the company withheld shares on behalf of Armstrong to cover the taxes from the acquisition. So the transactions in this filing were not optional and automatic. The CEO still held the same number of indirect shares after the sale, but was left with 91,737 direct shares, worth about $11.34 million as of Jan. 31.
Palomar stock had a strong year in 2025, and even though shares fell approximately 8% last month, Wall St. remains very bullish on the stock, as the specialty insurance market continues to grow and the frequency of natural disasters has spiked and is expected to persist in the long term.
