The withholding occurred on 2026-06-15 at a reported price of $23.37 per share, totaling roughly $74,574.

• Total value disposed: approximately $74,574.
• Shares owned after transaction: filing notes included unvested RSUs of 198,684 (per footnote); the filing’s reported beneficial ownership beyond that was not provided here.
• Footnotes: F1 = shares withheld by issuer to satisfy tax withholding on RSU vesting; F2 = includes 198,684 unvested RSUs.

Context

• This was a routine tax-withholding (cashless) action tied to RSU vesting rather than an intentional market sale or purchase. Such withholdings are common and generally reflect tax obligations on vested awards rather than a signal of insider sentiment.
