• Footnotes: F1 — vesting occurred because the Compensation & Human Capital Management Committee determined performance conditions were met for RSUs granted Aug 7, 2023. F2 — the shares sold were to cover tax withholding and remittance obligations related to the RSU vesting.
• Filing: Form 4 filed Aug 11, 2026 reporting the Aug 7 and Aug 10 transactions; no late filing indication in the report.

Context

These transactions reflect a performance-RSU vesting event (award at $0) followed by a routine sell-to-cover for taxes. Such sell-to-cover transactions are common after equity compensation vests and are not, by themselves, a clear signal of CEO sentiment about the company’s stock price.
