Context

• This was an exercise-plus-sale (often called a cashless or sell-to-cover style transaction): the options were exercised and the resulting shares were immediately sold, converting the option value to cash. Such transactions are common for compensatory option exercises and do not by themselves indicate a change in the insider’s longer-term view of the company.
• The 10b5‑1 designation amendment suggests the trades may have been made pursuant to a prearranged trading plan, but the filing here only corrects the checkbox — it does not include the plan details.
