Key Details

• Transaction date and price: 2025-12-02, 1,025 shares at $29.34 each.
• Total proceeds: $30,069.
• Transaction code: S (sale); footnote F1 indicates the sale was to cover tax withholding on vested RSUs.
• Shares owned after the transaction: not specified in the filing.
• Filing date vs. transaction date: Form 4 was filed March 16, 2026 for a December 2, 2025 transaction — this filing appears late, which reduces short-term transparency for investors.

Context

• Sales to cover tax withholding on vested restricted stock units are common and typically reflect tax obligations rather than a directional view on the company’s prospects. This was not a purchase or option exercise signaling additional insider accumulation.
