• Tax withholding/disposition: 8,603 shares withheld at $109.45 = $941,598 (reported as disposition code F).
• Footnotes: F1 — These were performance-based RSUs granted 3/1/2023; 179.1% of the original grant was earned and vested as of 3/1/2026; each vested unit settled into one common share. F2 — Shares withheld to satisfy tax withholding; because 3/1/2026 was a Sunday, the withholding used the issuer’s closing price on 2/27/2026.

Context This was a compensation-related vesting of performance-based RSUs (not an open-market purchase or a voluntary sale). The tax withholding (code F) is a routine disposition to satisfy tax obligations and does not by itself indicate the insider’s view of the company’s prospects. The award reflects achievement of pre-established performance targets (earned at 179.1% of target).
