Prevost Patrick M. 4

What Happened

• Patrick M. Prevost, a director of MATERION Corp (MTRN), was awarded a total of 17.445 restricted stock units (RSUs) on March 6, 2026 — 15.445 RSUs as an award and 2 RSUs acquired as reinvested dividend equivalents. The units were granted at $0.00 (i.e., awarded as compensation), so no cash was paid by the insider.

Key Details

• Transaction date: 2026-03-06; Form 4 filed 2026-03-10 (timely filing within required business days).
• Award details: 15.445 RSUs (primary award) and 2 RSUs (derivative, from reinvested dividend equivalents).
• Price: $0.00 per unit (awarded, not purchased); total cash cost to insider = $0.
• Shares owned after transaction: not specified in the filing excerpt.
• Footnotes: F1—each RSU represents one share of MTRN common stock; F2—the 2 dividend-equivalent RSUs will vest at the same time as the related RSUs (earlier of May 8, 2026 and the date of the next annual meeting); F3 referenced but not material to these RSUs.

Context

• RSUs are a form of compensation that convert into shares upon vesting; this award is routine compensation (not an open-market purchase or sale) and does not by itself indicate an immediate buy/sell view by the insider.
• The derivative RSUs were created by reinvesting dividend equivalents and will vest on the same schedule as the related RSUs.
