Key Details

• Transaction dates and prices:
  • 2025-04-07: 20 shares @ $73.61 = $1,472
  • 2025-04-14: 20 shares @ $81.45 = $1,629
• Shares owned after the transactions: Not specified in the information provided in this summary.
• Footnotes of note:
  • F1: This is an amended filing correcting price/nature errors in a prior report filed 01/27/2026.
  • F2: The purchased shares are held in a managed account under an investment adviser's discretion; the reporting person disclaims beneficial ownership of these shares.
  • F3: Some shares are attributed to the reporting person's account in the issuer's 401(k) plan as of the filing date.
• Filing timeliness: The report (period of report 2025-04-07) was amended and filed on 2026-02-10; the amendment corrects an earlier filing and indicates late/corrected reporting.

Context
Because the purchases were made in a managed account where an adviser has trading discretion (F2), the transactions may reflect adviser decisions rather than direct, discretionary purchases by the executive. The dollar amounts are small (~$3.1k total), so these trades are immaterial in size and may be routine. The amended, late filing reduces the timeliness of the disclosure for investors.
