Insights

TL;DR: Routine tax-withholding on equity vesting; no governance red flags.

The Form 4 shows standard withholding of 1,071 shares to satisfy minimum tax obligations from vesting of PSUs and RSUs. Transactions are coded as F, consistent with share withholding for taxes rather than open-market dispositions. The sequence of beneficial ownership figures confirms incremental withholdings, leaving 28,015 shares beneficially owned. This disclosure is procedural and does not indicate a change in board-level alignment or control.

TL;DR: Compensation-driven withholding of vested equity; expected and non-material.

The explanations tie each withheld lot to specific grant dates and award types (PSUs and RSUs) under the 2015 Stock Incentive Plan and the 2025 Omnibus Plan. The per-share amount shown ($283.36) appears as the valuation used for withholding. Total withheld shares (1,071) are modest relative to institutional holdings and reflect tax-related share retention rather than an intent to monetize holdings.
