Key Details

• Transaction date: 2026-03-01; Price: $45.48; Shares disposed: 184; Total value: $8,368.32.
• Transaction type/code: F — payment of exercise price or tax liability (tax withholding).
• Shares owned after transaction: not specified in the Form 4 filing.
• Filing date: 2026-03-03 (filed within the typical two-business-day Form 4 window).
• Relevant footnotes: F1/F3 indicate these were matching/allocated restricted stock units from the Company’s 2018 Management Stock Purchase Plan tied to deferrals of salary/incentive pay. F2/F4 explain vesting/forfeiture and that the RSUs are ultimately payable in cash per plan terms.

Context: This was a routine tax-withholding disposition related to RSUs, a common administrative action when awards vest or become payable. Such transactions are not direct purchases or investment signals; the filing shows tax-related share disposition rather than an open-market sale for investment reasons.
