Key Details

• Transaction date: 2026-01-24; Filing date: 2026-01-27 (filing does not indicate lateness).
• Vested/converted: 2,758 RSUs -> 2,758 shares (reported as M: exercise/conversion of derivative, $0 exercise price).
• Tax withholding: 1,141 shares disposed at $128.70 each = $146,847 (reported as F: payment of tax liability).
• Net shares delivered to insider: 1,617 shares.
• Footnotes: F1 notes each RSU is a contingent right to cash or one common share. F2 notes these RSUs were granted Jan 29, 2021 and vest in five equal annual installments beginning Jan 24, 2022; the issuer may elect to deliver cash or shares on vesting.

Context

• This was a routine vesting/settlement of RSUs, not an open-market sale of previously owned shares. The withholding of shares to cover taxes is a common administrative step and does not necessarily indicate a view on the company’s prospects.
• For retail investors, purchases are typically more informative than routine vesting/withholding; here the transaction simply reflects scheduled compensation vesting and tax payment.
