REDDY N MOHAN 4

What Happened

• Reddy N. Mohan, a director of MATERION Corp (MTRN), had 2,006 restricted stock units (RSUs) convert to 2,006 shares on May 7, 2026 (transaction code M). The filing shows an acquisition of 2,006 shares on conversion and a simultaneous disposition of 2,006 shares at $0.00 per share. No proceeds are reported from the disposition.

Key Details

• Transaction date: 2026-05-07; Form 4 filed: 2026-05-11 (appears timely).
• Acquisition: 2,006 shares from conversion of RSUs (price N/A).
• Disposition: 2,006 shares at $0.00 (derivative disposition).
• Footnotes: F1—each RSU equals one share; F2—these shares were issued upon vesting of an RSU award granted May 8, 2025 that vested May 7, 2026; F3—expiration date = date exercisable.
• Shares owned after the transaction are not shown in the excerpt of the filing.

Context

• These were RSUs that vested and converted into common shares. The subsequent disposition at $0.00 per share commonly indicates shares were withheld or surrendered to satisfy tax-withholding obligations rather than sold on the open market. This type of conversion/withholding is administrative and does not necessarily signal a buy or sell decision by the insider.
