Context
This was an exercise of vested options (derivative code M) followed by open-market sales. Exercising options and immediately selling some or all of the resulting shares is common and may be done for liquidity or tax purposes; it does not by itself indicate the director’s longer-term view of the company. The filing appears timely (reported the next day).
