Context

• 10b5-1 plans allow insiders to sell shares under a pre-set plan and are generally viewed as prearranged/routine dispositions rather than a new signal of insider conviction.
• These are sales (code “S”); sales alone do not indicate company performance or insider expectations. For retail investors, purchases typically carry more weight as a bullish signal.
• If you want transaction-level pricing breakdowns within the reported weighted-average ranges, the filing notes the reporting person will provide that detail to the issuer, SEC staff, or any security holder upon request.
