Context

• The sale was executed under a pre-established 10b5-1 trading plan, which allows insiders to sell shares according to a preset schedule and is commonly used to avoid timing disputes; it does not, by itself, indicate the insider’s current view of the company. The filing appears timely (Form 4 filed two days after the transaction).
