Key Details

• Transaction date: 2026-05-14
• Transaction type: Sale (open market/private sale) — 3,300 shares at $92.13 each; total ≈ $304,029
• Filing date / Period of report: 2026-05-14 (filed same day) — no late filing indicated in the report
• Footnote: Sale executed under a written Rule 10b5-1 trading plan established by Ms. Day on May 20, 2024 (footnote F1)

Context
Sales made under an established 10b5-1 plan are pre-scheduled trades and are often routine; they do not necessarily reflect the insider’s current view of the company. The filing corrects a prior reporting error (342-share overstatement), improving the accuracy of reported insider holdings.
