Key Details

• Transaction date: May 14, 2026. Filing date: May 18, 2026 (timely — within 2 business days).
• Transaction codes: M = exercise or conversion of a derivative security.
• Share counts and prices: 3,286 shares acquired @ $0.00; 3,286 shares disposed @ $0.00.
• Shares owned after the transaction: not specified in the disclosed entries.
• Footnotes of note:
  • F1: The shares are held in trust for the reporting person's children; the spouse is trustee.
  • F2: Each restricted stock unit represents a right to one share.
  • F3: The RSUs were granted on May 14, 2025 and vested on/after May 14, 2026 (or at the 2026 annual meeting).

Context
This appears to be a routine vesting/conversion of RSUs rather than an open-market buy or sale. The immediate disposition into a family trust is a transfer, not a market sale, and therefore should not be read as a directional signal on company stock. The M code and the footnotes together indicate conversion of previously granted RSUs into shares and transfer to a trust for the reporting person's children.
