• Transaction date: 2026-03-13 (filed on 2026-03-17, within the 2 business-day SEC filing window)
• Prices and values: award 221.887 shares @ $46.42 ≈ $10,300; open-market purchase 5.386 shares @ $46.42 ≈ $250; total ≈ 227.273 shares / $10,550
• Shares owned after transaction: not disclosed in the Form 4 summary provided / not specified in this report
• Footnotes: F1 — execution date determined per SEC Rule 16a-3(g)(2) & (g)(4); F2 — award shares were director compensation under the company’s director compensation plan; F3 — the reported amount includes shares purchased via automatic dividend reinvestment (DRIP), which are exempt from Section 16 reporting
• Filing timeliness: filed March 17, 2026 — appears timely (within two business days)

Context

• The larger piece of this activity was a compensation award for board service (typical director equity compensation), while the small open-market buy increases the director’s stake slightly.
• DRIP-related share reinvestments can be exempt from Section 16 reporting per the filing footnote, so reported totals may include exempt reinvested shares.
• These transactions are routine insider acquisitions (not sales); they are factual events and do not by themselves indicate the director’s intent or future company performance.
