What this transaction means for investors

It’s been a tough stretch for Palomar. Despite strong profit and revenue beats in the fourth quarter, the firm’s stock has faced pressure due to worse-than-expected underwriting results. The recent plunge erased what has otherwise been a years-long stretch of solid gains. Nevertheless, the recent sale appears to be routine rather than any sign of underlying issues, especially since, fundamentally, Palomar is performing solidly. In 2025, net income surged by 67.6% to reach $197.1 million, with adjusted net income climbing 62% to $216.1 million. According to the firm’s fourth-quarter earnings release, growth was driven by gross written premiums rising by 31.5% to $2 billion, and net earned premiums climbing over 57%.

All of that to say, the company is clearly growing, and the level of insider selling we're seeing here doesn’t change that. Armstrong attributed the firm’s “exceptional” year, in part, to the “successful” acquisitions of Advanced Ag Protection and The Gray Casualty and Surety Company. The firm is expected to report earnings again early next month, and that’ll ultimately matter much more. As long as the company can maintain its underwriting discipline, it has room to grow.
