Toth Robert B 4

What Happened
Robert B. Toth, a director of MATERION Corp (MTRN), reported derivative activity and an award-related issuance. The Form 4 shows an exercise/conversion of derivative securities for 2,006 shares dated May 7, 2026 (entries include both an acquisition and a corresponding disposition line, each showing $0 price). Separately, 758 shares were issued on May 8, 2026 pursuant to the vesting of restricted stock units (RSUs) that vested May 7, 2026; those RSU shares were reported as granted/acquired at $0. No cash purchase price or sale proceeds are reported in the filing.

Key Details

• Transaction dates: May 7, 2026 (exercise/conversion of derivative for 2,006 shares) and May 8, 2026 (issuance of 758 shares from RSU vesting).
• Reported prices/values: $0 reported for the derivative lines and the RSU issuance; no dollar proceeds or cash paid are shown.
• Footnotes: F1 = each RSU equals one share; F2 = the 758 shares were issued under an RSU grant made May 8, 2025 that vested May 7, 2026; F3–F4 describe vesting/exercise timing.
• Shares owned after transaction: not specified in the provided summary of the filing.
• Filing timeliness: Form 4 filed May 11, 2026 for a May 7 transaction — appears to be filed within the required two business days, so not late.

Context

• RSU issuances are typically compensation vesting events (not open-market purchases) and do not necessarily signal a buy/sell decision by the insider.
• "M" (exercise/conversion of derivative) entries indicate conversion of derivative instruments (e.g., options or similar); because the filing shows $0 prices and includes both acquisition and disposition lines for the 2,006-share entry, it reflects a non‑cash conversion/transfer step rather than a straightforward market purchase or sale.
• No evidence in the reported lines of an open-market sale or purchase of common stock — this looks like routine vesting/conversion activity rather than active trading.
