• Price / value: No cash price or market value reported in the filing for the shares acquired.
• Shares owned after transaction: not stated in the provided filing.
• Footnotes: F1–F3 explain these shares were delivered upon vesting/settlement of RSUs granted on May 21, 2025, which vest in full upon the earlier of the day before the issuer’s 2026 annual meeting or May 21, 2026.

Context

• This was a compensation-related settlement of RSUs (a non‑cash event), not an open‑market buy or sale. Such conversions typically reflect standard equity compensation vesting rather than a deliberate market-timing trade by the insider. The derivative conversion (code M) simply reflects the RSU-to-share settlement; no immediate sale or cash proceeds were reported.
