- Shares sold: 25,000 total; Aggregate proceeds: ~$7.70 million.

Context
- Sales made under a Rule 10b5-1 plan are typically prearranged and do not by themselves indicate a change in the insider’s view of the company; they are often used to allow routine disposition of shares while avoiding accusations of trading on material nonpublic information.
- As a 10% owner (not solely an executive trade), these filings reflect large-holder dispositions. Retail investors should view this as factual disclosure of insider selling activity but avoid inferring motivation from the sale alone.
