- Shares owned after the transactions: not specified in the provided filing.
- Timeliness: Filing date 2026-07-21. The 7/16 and 7/17 transactions appear to have been reported after the SEC’s typical two-business-day window (i.e., late); the 7/20 transaction was filed within one business day.
Context
- These were sell-to-cover/tax-withholding transactions tied to RSU vesting, a common administrative action that does not necessarily reflect the insider’s view of the company’s prospects. For retail investors, purchases by insiders tend to be more informative than routine withholding sales.
