Prajzner Edward J 4

What Happened

• Edward J. Prajzner, Senior EVP and Chief Financial Officer of Mistras Group, was granted 37,202 restricted stock units (RSUs) on Feb 25, 2026 (reported at $0.00 per share). On Feb 28, 2026, 1,303 shares were disposed of to satisfy tax withholding obligations at $15.28 per share, yielding $19,910. The RSU award is a performance-based grant.

Key Details

• Grant date: 2026-02-25 — 37,202 RSUs granted (reported price $0.00).
• Tax withholding sale: 2026-02-28 — 1,303 shares sold at $15.28 each for $19,910 (transaction code F).
• Vesting: The award vests 25% on each December 31 in 2026, 2027, 2028 and 2029 (per filing footnote).
• Shares owned after the transactions: not specified in this Form 4.
• Filing/timeliness: Form 4 filed on 2026-03-06; Form 4s are generally due within two business days of the transaction, so this filing appears later than typical.

Context

• The primary event is an RSU grant (an acquisition/award). The small sale three days later was a tax-withholding disposition — a common administrative step when RSUs vest or are paid out — and doesn’t necessarily signal an investment decision. This is not an open-market purchase or sale for cash liquidity beyond satisfying withholding.
