Context

• This transaction was effected under a pre-established 10b5-1 plan to cover tax withholding tied to RSU vesting, which is a common reason insiders sell shares and does not necessarily indicate a change in view on the company.
• Sales are generally less informative than purchases for signaling conviction; this appears to be routine tax-related selling rather than an opportunistic purchase or exercise.
