Context

• This was an option exercise (an acquisition) combined with share sales. Selling shares to cover taxes or immediately after exercising options is a common administrative action (often called a cashless exercise/tax withholding) and does not necessarily indicate a change in the insider’s view of the company. The presence of a 10b5‑1 plan means the exercise and sales were executed under a prearranged trading plan adopted on September 19, 2025.
