Key Details

• Transaction date: 2026-07-01; filing date: 2026-07-02 (appears timely).
• Award: 61.6 stock units valued at $175.60 each; total value $10,817.
• Shares owned after transaction: not specified in the provided filing.
• Footnote: these are stock units payable automatically on a 1-for-1 basis in shares of common stock (i.e., each unit converts to one share).
• Transaction code: A = Award/Grant.

Context
This was a compensation-related award (stock units/RSU-style) to a director and is generally part of routine board compensation rather than an open-market investment decision. Stock units will convert 1-for-1 into common shares per the footnote, which means the award increases his future share holdings when vested/paid.
