Fashinpaur Melissa A 4

What Happened

• Melissa A. Fashinpaur, Chief Accounting Officer of MATERION Corp (MTRN), was granted/acquired 1 restricted stock unit (RSU) on 2026-06-12. The RSU was recorded at $0.00 cash consideration (derivative award), and the Form 4 was filed on 2026-06-16.
• This was an award/acquisition (transaction code A), not an open-market purchase or sale. The cash value recorded for the transaction is $0; market value upon vesting or delivery is not disclosed in the filing.

Key Details

• Transaction date: 2026-06-12; Form 4 filed: 2026-06-16 (filed within the SEC two-business-day window).
• Transaction type: Award/Grant of a derivative (1 RSU) at $0.00.
• Shares owned after transaction: not specified in the provided data.
• Footnotes from the filing:
  • F1: Each restricted stock unit represents a right to receive one share of MTRN common stock.
  • F2: These RSUs were acquired upon reinvestment of dividend equivalents and will vest at the same time as the related RSUs.
  • F3: Expiration Date is the same as the Date Exercisable (not typically applicable to standard RSUs but included in the filing).
• Materiality: Single RSU is immaterial in size and typically an administrative/compensation-related entry.

Context

• RSUs are a form of equity compensation that convert to shares (if and when they vest); this award does not indicate a market purchase or sale by the insider.
• Dividend-equivalent RSUs (per F2) are commonly reinvested into additional RSUs and vest on the same schedule as the underlying grant, so this reflects routine compensation mechanics rather than a trading signal.
