In a series of transactions disclosed in a recent SEC filing, Derek J. Maetzold, President and CEO of Castle Biosciences Inc . (NASDAQ:CSTL), has sold shares worth approximately $585,673. The sales, executed on March 7 and March 10, 2025, involved multiple trades at prices ranging from $19.518 to $20.744 per share. The timing of these sales coincides with the stock’s recent 14.8% decline over the past week, according to InvestingPro data.

The transactions were part of a prearranged trading plan under Rule 10b5-1, which allows company insiders to set up a predetermined schedule for buying or selling shares.

Following these transactions, Maetzold retains a significant stake in Castle Biosciences, with shares held directly and through various trusts. The company, based in Friendswood, Texas, specializes in medical laboratory services and maintains a strong financial position with a healthy current ratio of 7.29 and more cash than debt on its balance sheet. The company generated $332 million in revenue over the last twelve months, with an impressive gross margin of 82%.

In other recent news, Castle Biosciences Inc. reported a significant earnings beat for the fourth quarter of 2024, with an earnings per share (EPS) of $0.32, far surpassing the analyst forecast of $0.01.
