Context

• These sales were conducted under a prearranged 10b5‑1 plan, which typically means trades were scheduled in advance and do not necessarily signal a change in the holder’s view of the company. As a 10% owner (not identified as an executive here), this represents institutional/major‑holder selling rather than an executive-directed sale.
