EDMAN THOMAS T 4

What Happened

• Thomas T. Edman, a director of MATERION Corp (MTRN), received a grant of 758 restricted stock units (RSUs) on 2026-05-08. The grant is reported as a derivative award (transaction code A) at a reported price of $0.00 (no cash paid). Each RSU represents a right to receive one share of MTRN common stock upon vesting.

Key Details

• Transaction date: 2026-05-08; Form 4 filed: 2026-05-11.
• Grant size and price: 758 RSUs at $0.00 (derivative award).
• Shares owned after transaction: not specified in the filing.
• Vesting: RSUs generally vest on the earlier of (1) the first anniversary of the grant date or (2) the next annual meeting of shareholders (per footnote).
• Other footnotes: F1 = each RSU converts to one share; F2 = vesting schedule as noted; F3 = "Expiration Date is the same as the Date Exercisable" (as reported).
• Timeliness: Form 4 was filed three calendar days after the grant (May 11 reporting a May 8 grant); whether this meets the SEC’s two-business-day rule depends on business-day counting.

Context

• RSU grants are a form of compensation for directors and do not transfer actual shares until they vest; they are not an open-market purchase or sale. Such awards are routine for board members and should be interpreted as compensation rather than a direct market sentiment signal.
