Proto Labs (PRLB) COO Michael R. Kenison Receives RSU Awards; 531 Shares Withheld for Taxes

What Happened
Michael R. Kenison, Chief Operations Officer of Proto Labs (PRLB), received equity awards on 2026-02-25 and had 531 shares disposed to satisfy tax withholding. The filing shows an acquisition (award) of 2,415 shares (ordinary shares) and a separate derivative award of 4,404 restricted stock units (RSUs). To cover the tax liability associated with vesting/awarding, 531 shares were withheld/disposed at $62.63 per share, totaling about $33,257.

Key Details

  • Transaction date: February 25, 2026; Form 4 filed February 27, 2026 (appears timely).
  • Awards: 2,415 shares (granted/acquired) + 4,404 RSU derivative award (total 6,819 shares awarded). Transaction code: A (award/grant).
  • Tax withholding: 531 shares disposed/withheld at $62.63 each to cover taxes; proceeds ≈ $33,257. Transaction code: F (tax withholding).
  • Vesting: Footnotes state both awards vest 25% on Feb 25, 2027 and 25% on each Feb 25 thereafter until fully vested.
  • Shares owned after the transaction: not specified in the provided excerpt of the filing.

Context

  • This is primarily an award of RSUs, not an open-market purchase or a sale for investment reasons; the 531-share disposition reflects tax withholding (a routine administrative action).
  • RSUs vest over multiple years (annual 25% tranches), so these shares are subject to future vesting conditions.
  • No 10b5-1 plan, gift, or option exercise details are reported in the provided data.
