• Individual transactions:
  • 2026-03-13: 20.526 shares @ $54.66 = $1,122 (acquired)

  • 2026-03-27: 281.939 shares @ $51.53 = $14,528 (acquired)
• These are acquisitions (a bullish signal is sometimes inferred for purchases), but they were made through automatic reinvestment of dividends rather than open-market buys.

Key Details

• Transaction dates and prices: see list above (Mar 13 and Mar 27, 2026).
• Total shares acquired: 555.352; total reported value: ~$29,483.
• Footnote: F1 — shares were acquired under a dividend reinvestment plan and the transaction is described as exempt from Section 16 under Rule 16a-11.
• Transaction code: "J" (other acquisition/disposition) with the DRIP explanation in the footnote.
• Shares owned after the transactions: not specified in the provided filing details.
• Filing timeliness: Form filed 2026-04-03 reporting trades on 2026-03-13 and 2026-03-27; the Mar 27 trades appear to have been reported more than two business days after the transaction date, so this filing may be late.

Context

• Dividend reinvestment (DRIP) purchases are routine: the insider used dividends to buy additional shares rather than receiving cash, and these transactions are often exempt from some Section 16 reporting requirements under Rule 16a-11.
• Because this was a DRIP acquisition (not an open-market purchase or option exercise), it generally reflects reinvestment of income rather than a directional trade based on new information.
