• These were acquisitions (buys), but they were routine dividend reinvestment purchases rather than open-market buys.

Key Details

• Transaction dates and prices:
  • 2026-03-13: 63.411 sh @ $54.66 ($3,466) and 168.097 sh @ $54.89 ($9,227).
  • 2026-03-27: 75.932 sh @ $52.92 ($4,018) and 207.583 sh @ $51.53 ($10,697).
• Total acquired: 515.023 shares for ≈ $27,408.
• Shares owned after the transactions: not specified in the provided Form 4.
• Footnote: F1 — Shares were acquired under a dividend reinvestment plan; the filing notes these dividend reinvestment transactions are exempt under Rule 16a-11 (routine automatic reinvestment).
• Timeliness: The Form 4 was filed on 2026-04-03, which is more than two business days after the March transactions; the filing therefore appears to have been submitted late.

Context

• Dividend reinvestment plan purchases are automatic transactions that use cash dividends to buy additional shares; they are common and typically viewed as routine rather than a special display of insider conviction.
• Because these purchases were through the company's DRIP and exempt under Rule 16a-11, they differ from discretionary open-market buys by insiders.
