Duolingo (DUOL) General Counsel exercises stock options, now holding 52,865 shares
Duolingo's General Counsel, Stephen C. Chen, exercised stock options to acquire 58 shares of Class A Common Stock at $14.42 per share. This was a routine, compensation-related transaction and not an open-market sale, increasing his direct holdings to 52,865 Class A shares. The options were fully vested and exercisable, and the filing indicates no further derivative balance for that specific grant.
