What this transaction means for investors

Koblinski sold a total of 300,000 shares within that four-month period, with each share averaging $65.43, totaling approximately $19.63 million. But the CEO isn't the only insider who sold shares towards the end of 2025.

Karman’s CFO, COO, CGO, and a director all sold shares during the week of Nov. 10, averaging 85,250 shares each at $63.56 per share for an average transaction value of $5.42 million.

The flurry of insider sales to end 2025 isn't too alarming when considering the stock has been surging since the company's IPO on Feb. 13, 2025.

Every month since then has resulted in price gains, outside of November, and the stock is already up 38% YTD (as of Jan. 9). With a forward price-to-earnings (P/E) ratio of nearly 200, there are significantly high expectations for the stock's growth, and investors should consider this stock for their portfolio.
